To study the effects of lifestyle intervention in pregnancy on weight retention 6 months postpartum among obese women from the "Lifestyle in Pregnancy" (LiP) study, and to determine associations between breastfeeding with postpartum maternal weight. Six months postpartum follow up after a randomized controlled intervention trial. Two university hospitals in Denmark. A total of 360 women with pregestational body mass index ≥30 kg/m(2) . The intervention involved lifestyle changes (diet and exercise) during pregnancy. The control group received routine pregnancy care. Both groups received standard postnatal care. Gestational weight gain, postpartum weight retention and breastfeeding. Follow up was completed in 238 women of whom 46% in the intervention group and 57% in the control group had retained weight 6 months postpartum (p = 0.088). Women with gestational weight gain ≤9 kg, (recommended by the Institute of Medicine), retained less postpartum weight compared with those who exceeded 9 kg (median -0.7 vs. 1.5, p < 0.001). Ninety-two percent in both weight gain groups initiated breastfeeding. The number of breastfeeding mothers was higher among women with postpartum weight retention ≤5 kg compared with those with weight retention > 5 kg (94% vs. 85%, p = 0.034). We could not detect sustained weight control at 6 months postpartum despite a lower gestational weight gain for obese women during pregnancy who received a lifestyle intervention rather than standard care. Women who adhered to gestational weight gain recommendations had significantly lower postpartum weight retention. Breastfeeding for 6 months was negatively associated with postpartum weight retention. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

The objectives of this study were to assess the efficacy of lifestyle intervention on gestational weight gain in pregnant women with normal and above normal body mass index (BMI) in a randomized controlled trial. A total of 116 pregnant women (<20 weeks of pregnancy) without diabetes were enrolled and 113 pregnant women completed the program. Participants were randomized into intervention and control groups. Women in the intervention group received weekly trainer-led group exercise sessions, instructed home exercise for 3-5-times/week during 20-36 weeks of gestation, and dietary counseling twice during pregnancy. Participants in the control group did not receive the intervention. All participants completed a physical activity questionnaire and a 3-day food record at enrolment and 2 months after enrolment. The participants in the intervention group with normal pre-pregnancy BMI (≤24.9 kg/M2, n = 30) had lower gestational weight gain (GWG), offspring birth weight and excessive gestational weight gain (EGWG) on pregnancy weight gain compared to the control group (n = 27, p < 0.05). Those weight related-changes were not detected between the intervention (n = 27) and control group (n = 29) in the above normal pre-pregnancy BMI participants. Intervention reduced total calorie, total fat, saturated fat and cholesterol intake were detected in women with normal or above normal pre-pregnancy BMI compared to the control group (p < 0.05 or 0.01). Increased physical activity and reduced carbohydrate intake were detected in women with normal (p < 0.05), but not above normal, pre-pregnancy BMI at 2 months after the onset of the intervention compared to the control group. The results of the present study demonstrated that the lifestyle intervention program decreased EGWG, GWG, offspring birth weight in pregnant women with normal, but not above normal, pre-pregnancy BMI, which was associated with increased physical activity and decreased carbohydrate intake.

As obesity rates rise, new weight-loss methods are needed. Little is known about the use of podcasting (audio files for a portable music player or computer) to promote weight loss, despite its growing popularity. A 12-week RCT was conducted. The study sample comprised overweight men and women (BMI=25-40 kg/m(2); n=78) in the Raleigh-Durham NC area. In 2008, participants were randomly assigned to receive 24 episodes of a currently available weight-loss podcast (control podcast) or a weight-loss podcast based on social cognitive theory (SCT) designed by the researchers (enhanced podcast) for 12 weeks. Weight was measured on a digital scale at baseline and follow-up. Both groups also completed questionnaires assessing demographic information, food intake, physical activity, and SCT constructs at the introductory and 12-week meetings. Additional questionnaires at the 12-week meeting assessed perceptions of the intervention. Data collection and analysis occurred in 2008 and intention-to-treat was used. Enhanced group participants (n=41) had a greater decrease in weight (-2.9+/-3.5 kg enhanced group vs -0.3+/-2.1 control group; p<0.001 between groups) and BMI (-1.0+/-1.2 kg/m(2) enhanced group vs -0.1+/-0.7 kg/m(2) control group; p<0.001 between groups) than the control group (n=37) and had greater weight-loss-related knowledge (p<0.05), elaboration (p<0.001), and user control (p<0.001) and less cognitive load (p<0.001). The results of this study suggest that the use of behavioral, theory-based podcasting may be an effective way to promote weight loss. NCT00771095.

Background It has not been established whether control conditions with large weight losses (WLs) diminish expected treatment effects in WL or prevention of weight gain (PWG) randomized controlled trials (RCTs). Subjects/Methods We performed a meta-analysis of 239 WL/PWG RCTs that include a control group and at least one treatment group. A maximum likelihood meta-analysis framework is used in order to model and understand the relationship between treatment effects and control group outcomes. Results Under the informed model, an increase in control group WL of one kilogram corresponds with an expected shrinkage of the treatment effect by 0.309 kg [95% CI (−0.480, −0.138), p = 0.00081]; this result is robust against violations of the model assumptions. Conclusions We find that control conditions with large weight losses diminish expected treatment effects. Our investigation may be helpful to clinicians as they design future WL/PWG studies.

Tamarind water extract has been shown to demonstrate an anti-obesity effect. In this research, long-term use of tamarind pulp water extract safety was evaluated. Tamarind pulp was extracted by reflux method, followed by freeze-drying to obtain dry extract. Wistar rats were divided into six groups, with 20 animals of each sex per group. The control group and satellite control group received carboxymethylcellulose sodium (CMC-Na) 0.5% 1 mL/100 g bw (body weight) per day. Treatment groups received tamarind pulp extract at doses of 75, 200, 1000, satellite 1000 mg/kg bw per day for six months. After six months, control groups and the treatment group were sacrificed. Satellite groups were sacrificed one month later. Relative organ weights, hematology and clinical biochemistry profiles were determined. After six months, there were no significant change in body weight, hematologic, and clinical biochemistry profiles of the tested group. Body weight of male rats in the satellite 1000 mg/kg bw group was significantly increased in week 30 compared to the satellite control group ( p < 0.05). The relative spleen weight of female rats of the 200 mg/kg bw group was reduced ( p < 0.05). The relative kidney weight of male rats in the 1000 mg/kg bw group was increased ( p < 0.05). This study showed that tamarind pulp extract was generally safe and well tolerated at the tested dose.

To explore the relationship between mothers' body mass index (BMI) before pregnancy or weight gain during pregnancy and autism in children. From 2013 to 2014, the 181 children with autism and 181 healthy children matched by sex and age from same area were included in this study. According to mothers' BMI before pregnancy, the selected cases were divided into 3 groups: low, normal and high group. Then 3 groups were divided into 3 subgroups based on mother' s weight gain during pregnancy: low, normal and high group, according to the recommendations of Institute of Medicine. Logistic regression analysis and χ(2) test were conducted with SPSS 18.0 software to analysis the relationship between mothers' BMI before pregnancy or weight gain during pregnancy and autism in children. The age and sex distributions of case group and control group were consistent (χ(2)=0.434, P>0.05). The mothers' BMI before pregnancy of case group was higher than that of control group (χ(2)=9.580, P<0.05) ,which was (21.28±3.80) kg/m(2) for case group and (19.87±2.83) kg/m(2) for control group. The proportion of cases in high BMI group (10.5%) was much higher than that in control group (2.8%) . The risk of children with autism in high BMI group was 3.7 times higher than that in normal BMI group (OR=3.71, 95% CI: 1.34-10.24). In normal BMI group, the proportion of mothers who had excessive weight gain during pregnancy was higher in case group (44.1%) than in control group (33.9%). In high BMI group, the proportion of mothers who had excessive weight gain was higher in case group (52.6%) than in control group (20.0%) . In normal BMI group (χ(2) =8.690, P<0.05) and high BMI group (χ(2)=4.775, P<0.05), the weight gain during pregnancy was associated with autism in children. Logistic regression analysis showed that mothers' BMI before pregnancy (unadjusted OR=1.89, 95% CI: 1.26-2.85, adjusted OR=1.52, 95% CI: 1.19-2.27) and weight gain during pregnancy were the risk factors for autism in children (unadjusted OR=1.63, 95% CI: 1.08-1.25, adjusted OR=1.64, 95% CI: 1.21-2.21). Overweight or obesity before pregnancy and excessive weight gain during pregnancy were associated with autism in children, suggesting that women who plan to be pregnant should pay attention to body weight control.

To assess dietary intake, eating patterns, physical activity and eating behaviors, and to explore strategies and perceptions of the experience of weight maintenance in weight loss maintainers (weight loss maintenance (WLM) ≥ 10% weight loss maintained for ≥1 year) and in matched controls with a lifetime stable normal weight. Volunteers (32) were recruited by a snowball procedure in this cross-sectional, mixed-methods study. Diet, physical activity, and eating behaviors were assessed with validated questionnaires. Strategies and experiences were investigated during interviews. Descriptive coding, thematic analysis (qualitative data) as well as descriptive analysis and t-tests (quantitative data) were performed. Both groups had similar energy and macronutrient consumption. Those in the WLM group reported higher levels of exercise and scored higher on several dimensions of eating disorders. Four themes - 'food choices,' 'quantities and portion control,' 'physical activity', and 'burden' - emerged from the qualitative data. Both groups used similar weight maintenance strategies, but those in the WLM group experienced a higher burden, expressing effortful control which contrasted with the control group's confidence in their internal cues. Our results show an additional burden related with maintaining weight loss compared to keeping a stable normal weight. They provide evidence to devise interventions that will address the difficulty of regulating intake. © 2017 The Author(s) Published by S. Karger GmbH, Freiburg.

The aim of this project was to evaluate the effectiveness of using social media to augment the delivery of, and provide support for, a weight management program delivered to overweight and obese individuals during a twenty four week intervention. Participants randomly divided into either one of two intervention groups or a control group. The two intervention groups were instructed to follow identical weight-management program. One group received the program within a Facebook group, along with a support network with the group, and the other intervention group received the same program in a booklet. The control group was given standard care. Participants' weight and other metabolic syndrome risk factors were measured at baseline and at weeks 6, 12, 18 and 24. The Facebook Group reported a 4.8% reduction in initial weight, significant compared to the CG only (p = 0.01), as well as numerically greater improvements in body mass index, waist circumference, fat mass, lean mass, and energy intake compared to the Pamphlet Group and the Control Group. These results demonstrate the potential of social media to assist overweight and obese individuals with respect to dietary and physical activity modifications for weight management, and justify further research into the inclusion of social media in clinical weight management programs. It is anticipated that social media will provide an invaluable resource for health professionals, as a low maintenance vehicle for communicating with patients, as well as a source of social support and information sharing for individuals undergoing lifestyle modifications.

The study evaluates the effectiveness of Compelled Body Weight Shift (CBWS) approach in the rehabilitation of individuals with stroke. CBWS involves a forced shift of body weight towards a person's affected side by means of a shoe insert that establishes a lift of the nonaffected lower extremity. Eleven patients with acute stroke were randomly assigned to experimental and control groups. The experimental group received a two-week conventional physical therapy combined with CBWS and the control group received only a two-week conventional therapy. Weight bearing, Gait velocity, Berg's Balance, and Fugl-Meyer's Scores were recorded before and after the intervention. Weight bearing on the affected side increased in the experimental group and decreased in the control group. The increase in gait velocity with treatment was significant in both the groups ( P < 0.05). However, experimental group ( P = 0.01) demonstrated larger improvements in gait velocity compared to the control group ( P = 0.002). Berg Balance and Fugl-Meyer scores increased for both the groups. The implementation of a two-week intervention with CBWS resulted in the improvement in weight bearing and gait velocity of individuals with acute stroke. The present preliminary study suggests that CBWS technique could be implemented as an adjunct to conventional rehabilitation program for individuals with acute stroke.

Obesity and a sedentary lifestyle are associated with physical impairments and biologic changes in older adults. Weight loss combined with exercise may reduce inflammation and improve physical functioning in overweight, sedentary, older adults. This study tested whether a weight loss program combined with moderate exercise could improve physical function in obese, older adult women. Participants (N = 34) were generally healthy, obese, older adult women (age range 55-79 years) with mild to moderate physical impairments (ie, functional limitations). Participants were randomly assigned to one of two groups for 24 weeks: (i) weight loss plus exercise (WL+E; n = 17; mean age = 63.7 years [4.5]) or (ii) educational control (n = 17; mean age = 63.7 [6.7]). In the WL+E group, participants attended a group-based weight management session plus three supervised exercise sessions within their community each week. During exercise sessions, participants engaged in brisk walking and lower-body resistance training of moderate intensity. Participants in the educational control group attended monthly health education lectures on topics relevant to older adults. Outcomes were: (i) body weight, (ii) walking speed (assessed by 400-meter walk test), (iii) the Short Physical Performance Battery (SPPB), and (iv) knee extension isokinetic strength. Participants randomized to the WL+E group lost significantly more weight than participants in the educational control group (5.95 [0.992] vs 0.23 [0.99] kg; P < 0.01). Additionally, the walking speed of participants in the WL+E group significantly increased compared with that of the control group (reduction in time on the 400-meter walk test = 44 seconds; P < 0.05). Scores on the SPPB improved in both the intervention and educational control groups from pre- to post-test (P < 0.05), with significant differences between groups (P = 0.02). Knee extension strength was maintained in both groups. Our findings suggest that a lifestyle-based weight loss program consisting of moderate caloric restriction plus moderate exercise can produce significant weight loss and improve physical function while maintaining muscle strength in obese, older adult women with mild to moderate physical impairments.

Many overweight people take action to lose weight but most regain this weight. To examine the effectiveness of a weight maintenance intervention focused on regular self-weighing after receiving a 12-week weight loss programme. Quasi-randomized controlled trial of 3768 obese or overweight men and women. The intervention group (n = 3290) received two telephone calls, the offer of free weighing scales, encouragement to weigh themselves weekly and record this on a card. The main outcome was change in weight between 3 and 12 months. Using intention to treat analysis both groups regained weight; however, the intervention group on average regained 1.23 kg, whereas the control group regained 1.83 kg. Adjusting for covariates resulted in a mean difference of 0.68 kg (95% CI 0.12, 1.24) at 12-month follow-up. Encouraging people who have recently lost weight to weigh themselves regularly prevents some weight regain. © The Author 2013.

Our aim is to determine the effect of paced eating, exposure to an educational programme that promotes healthy eating habits and allowing the satiety reflex to limit food intake in controlling weight gain in healthy adolescents. Fifty-four healthy individuals consisting of 18 adolescent girls and 36 boys aged 12 ± 2 years were given recommendations for reducing eating rate without changing diet or meal size according to the educational programme 'good manners for a healthy future'. Each participant was provided with a 30-s portable hourglass to pace time between bites. Individuals using and not using the hourglass were placed either into an 'adhering' or a 'non-adhering' group, respectively. Control data were obtained from a similar population. Initially, the adhering group had higher weight compared with the non-adhering group (64.1 ± 13.2 vs. 56.2 ± 11.7 kg). Control group weight was no different from the study group at baseline (56.3 ± 10.3 kg). Weight in the adhering group decreased after the first semester of participation by 2.0 ± 5.7% and after a year by 3.4 ± 4.8%, while the non-adhering group gained weight by 5.8 ± 4.5% and 12.6 ± 8.3%. The control group increased weight after a year by 8.2 ± 6.5%. In total, 18 non-adhering and 14 adhering adolescents completed the study. This 1-year study shows a statistically significant association between rate of food intake and weight control in adherence to an educational programme directed at developing healthy eating habits. The proposed behavioural training may serve as an option for weight control in adolescents. © 2015 The Authors.

To report the weight loss findings after the first year of a lifestyle intervention trial among women with gestational diabetes mellitus (GDM). A total of 1180 women with GDM were randomly assigned (1:1) to receive a 4-year lifestyle intervention (intervention group, n = 586) or standard care (control group, n = 594) between August 2009 and July 2011. Major elements of the intervention included 6 face-to-face sessions with study dieticians and two telephone calls in the first year, and two individual sessions and two telephone calls in each subsequent year. Among 79% of participants who completed the year 1 trial, mean weight loss was 0.82 kg (1.12% of initial weight) in the intervention group and 0.09 kg (0.03% of initial weight) in the control group (P = .001). In a prespecified subgroup analysis of people who completed the trial, weight loss was more pronounced in women who were overweight (body mass index ≥24 kg/m 2 ) at baseline: mean weight loss 2.01 kg (2.87% of initial weight) in the intervention group and 0.44 kg (0.52% of initial weight) in the control group (P < .001). Compared with those in the control group, women in the intervention group had a greater decrease in waist circumference (1.76 cm vs 0.73 cm; P = .003) and body fat (0.50% vs 0.05% increase; P = .001). The 1-year lifestyle intervention led to significant weight losses after delivery in women who had GDM, and the effect was more pronounced in women who were overweight at baseline. © 2018 John Wiley & Sons Ltd.

Weight reduction programs are not generally designed or adapted for people with physical disabilities. This study examined the effect of a 9-months remote, telephone-based weight management program for people with physical disabilities using a Web-based system (Personalized Online Weight and Exercise Response System [POWERS]). A total of 102 participants (mean ± SD age, 46.5 ± 12.7 yrs; body mass index, 32.0 ± 5.8 kg/m(2)) with a physical disability (spinal cord injury, multiple sclerosis, spina bifida, cerebral palsy, stroke, or lupus) were randomized to one of three conditions: physical activity only (POWERS), physical activity plus nutrition (POWERS(plus)), and control. The POWERS group received a physical activity tool kit and regular coaching telephone calls. The POWERS(plus) group received an intervention identical to that of the POWERS group plus nutritional information. The control group received the physical activity tool kit and self-guided health promotion resources at the completion of the trial but no coaching. Postintervention differences in body weight were found between the groups. There was a significant group × time interaction (P < 0.01) in postintervention body weight, with both the POWERS and POWERS(plus) groups demonstrating greater reduction in body weight compared with the control group (POWERS: -2.1 ± 5.5 kg, -2.4 ± -5.9%; POWERS(plus): -0.5 ± 5.0 kg, -0.6 ± 4.3%; control: +2.6 ± 5.3 kg, 3.1 ± 7.4%). A low-cost telephone intervention supported with a Web-based remote coaching tool (POWERS) can be an effective strategy for assisting overweight adults with physical disabilities in maintaining or reducing their body weight.

Background Being overweight and obese are major risk factors for noncommunicable diseases such as cardiovascular diseases. The prevalence of overweight and obesity is high throughout the world and these issues are very serious in the Shunyi District in China. As mobile technologies have rapidly developed, mobile apps such as WeChat are well accepted and have the potential to improve health behaviors. Objective This study aims to evaluate the effectiveness of a mobile app (WeChat) as an intervention on weight loss behavior. Methods This study was conducted among an occupational population from August 2015 to February 2016 in the Shunyi District of Beijing. Before the intervention, the Shunyi District Government released an official document for weight loss to all 134 government agencies and enterprises in Shunyi District. Participants willing to use our official WeChat account were enrolled in a WeChat group and received 6 months of interventions for weight loss; those who were not willing to use the account were in a control group given routine publicity on weight loss. Results In total, 15,310 occupational participants including 3467 participants (22.65%) in the control group and 11,843 participants (77.35%) in the WeChat group were enrolled. Participants in the WeChat group lost more weight (mean 2.09, SD 3.43 kg) than people in the control group (mean 1.78, SD 2.96 kg), and the difference in mean weight loss between the two groups for males was significant based on the stratification of age and educational level. To control for confounding factors and to explore the effects of WeChat on weight loss, the propensity score method with a multinominal logistic regression was utilized. For males, this showed that the WeChat group (with both active and inactive subgroups) had a higher probability of maintaining weight, weight loss from 1 to 2 kg, or weight loss more than 2 kg than the control group. However, the control group had higher probability of weight loss from 0 to 1 kg. Being active in WeChat was likely to be associated with weight loss. The more active participants were in the weight loss program via WeChat, the more weight they lost. Conclusions The weight loss intervention campaign based on an official WeChat account focused on an occupation-based population in Shunyi District was effective for males. The more active male participants were in using WeChat, the more weight they lost. There might be no effect or there may even be a negative effect on weight loss for females. Future research should focus on how to improve adherence to the WeChat weight loss interventions, to improve and refine the WeChat content such as developing a variety of materials to attract interest, and to protect personal privacy, especially for females.

To investigate the long-term effects of changes in dietary carbohydrate/fat ratio and simple vs complex carbohydrates. Randomized controlled multicentre trial (CARMEN), in which subjects were allocated for 6 months either to a seasonal control group (no intervention) or to one of three experimental groups: a control diet group (dietary intervention typical of the average national intake); a low-fat high simple carbohydrate group; or a low-fat high complex carbohydrate group. Three hundred and ninety eight moderately obese adults. The change in body weight was the primary outcome; changes in body composition and blood lipids were secondary outcomes. Body weight loss in the low-fat high simple carbohydrate and low-fat high complex carbohydrate groups was 0.9 kg (P < 0.05) and 1.8 kg (P < 0.001), while the control diet and seasonal control groups gained weight (0.8 and 0.1 kg, NS). Fat mass changed by -1.3kg (P< 0.01), -1.8kg (P< 0.001) and +0.6kg (NS) in the low-fat high simple carbohydrate, low-fat high complex carbohydrate and control diet groups, respectively. Changes in blood lipids did not differ significantly between the dietary treatment groups. Our findings suggest that reduction of fat intake results in a modest but significant reduction in body weight and body fatness. The concomitant increase in either simple or complex carbohydrates did not indicate significant differences in weight change. No adverse effects on blood lipids were observed. These findings underline the importance of this dietary change and its potential impact on the public health implications of obesity.

Abstract The experiments reported here were conducted to investigate the effect of selection on three quantitative traits, namely cocoon weight, cocoon shell weight, and cocoon shell percentage, during four generations by rearing six pure breeds of domesticated silkworm, Bombyx mori L. (Lepidoptera: Bombycidae) of Chinese and Japanese origin compared with random unselected groups as controls. All stages of rearing and data recording were performed over four rearing periods, with generations 1–3 during successive spring seasons and generation 4 during the autumn season in year 3. Each pure line contained two groups of selected and random (control) groups. Comparisons included the effect of selection methods, pure line, and generation on the phenotypic values. We found strong main effects of pure line, generation, sex, and group and support for nearly all interactions between these main effects for all three response traits. The results indicated that cocoon weight and cocoon shell weight in the selected group were higher than in the control or nonselected group. Both selected and nonselected groups had the lowest cocoon weight, cocoon shell weight, and cocoon shell percentage in the fourth generation when environmental conditions during the autumn season were less favorable than spring. The cocoon weight and cocoon shell weight averages were higher for nonselected groups in the second and third generations, and for the selected group in the first generation due to the direct effect of selection.

Preventing obesity among young adults should be a preferred public health approach given the limited efficacy of treatment interventions. This study examined whether weight gain can be prevented by online approaches using two different behavioral models, one overtly directed at obesity and the other covertly. A three-group parallel randomized controlled intervention was conducted in 2012-2013; 20,975 young adults were allocated a priori to one control and two "treatment" groups. Two treatment groups were offered online courses over 19 weeks on (1) personal weight control ("Not the Ice Cream Van," NTICV) and, (2) political, environmental, and social issues around food ("Goddess Demetra," "GD"). Control group received no contact. The primary outcome was weight change over 40 weeks. Within-group 40-week weight changes were different between groups (P < 0.001): Control (n = 2,134): +2.0 kg (95% CI = 1.5, 2.3 kg); NTICV (n = 1,810): -1.0 kg (95% CI = -1.3, -0.5); and GD (n = 2,057): -1.35 kg (95% CI = -1.4 to -0.7). Relative risks for weight gain vs. NTICV = 0.13 kg (95% CI = 0.10, 0.15), P < 0.0001; GD = 0.07 kg (95% CI = 0.05, 0.10), P < 0.0001. Both interventions were associated with prevention of the weight gain observed among control subjects. This low-cost intervention could be widely transferable as one tool against the obesity epidemic. Outside the randomized controlled trial setting, it could be enhanced using supporting advertising and social media. © 2015 The Obesity Society.

Background: Breakfast is associated with lower body weight in observational studies. Public health authorities commonly recommend breakfast consumption to reduce obesity, but the effectiveness of adopting these recommendations for reducing body weight is unknown. Objective: We tested the relative effectiveness of a recommendation to eat or skip breakfast on weight loss in adults trying to lose weight in a free-living setting. Design: We conducted a multisite, 16-wk, 3-parallel-arm randomized controlled trial in otherwise healthy overweight and obese adults [body mass index (in kg/m2) between 25 and 40] aged 20–65 y. Our primary outcome was weight change. We compared weight change in a control group with weight loss in experimental groups told to eat breakfast or to skip breakfast [no breakfast (NB)]. Randomization was stratified by prerandomization breakfast eating habits. A total of 309 participants were randomly assigned. Results: A total of 283 of the 309 participants who were randomly assigned completed the intervention. Treatment assignment did not have a significant effect on weight loss, and there was no interaction between initial breakfast eating status and treatment. Among skippers, mean (±SD) baseline weight-, age-, sex-, site-, and race-adjusted weight changes were −0.71 ± 1.16, −0.76 ± 1.26, and −0.61 ± 1.18 kg for the control, breakfast, and NB groups, respectively. Among breakfast consumers, mean (±SD) baseline weight-, age-, sex-, site-, and race-adjusted weight changes were −0.53 ± 1.16, −0.59 ± 1.06, and −0.71 ± 1.17 kg for the control, breakfast, and NB groups, respectively. Self-reported compliance with the recommendation was 93.6% for the breakfast group and 92.4% for the NB group. Conclusions: A recommendation to eat or skip breakfast for weight loss was effective at changing self-reported breakfast eating habits, but contrary to widely espoused views this had no discernable effect on weight loss in free-living adults who were attempting to lose weight. This trial was registered at clinicaltrails.gov as NCT01781780. PMID:24898236

Socioeconomic status and weight control practices in British adults

PubMed Central

Wardle, J; Griffith, J

2001-01-01

STUDY OBJECTIVE—Attitudes and practices concerning weight control in British adults were examined to test the hypothesis that variation in concern about weight and deliberate weight control might partly explain the socioeconomic status (SES) gradient in obesity. Higher SES groups were hypothesised to show more weight concern and higher levels of dieting.
SETTING—Data were collected as part of the monthly Omnibus Survey of the Office of National Statistics in March 1999.
PARTICIPANTS—A stratified, probability sample of 2690 households was selected by random sampling of addresses in Britain. One randomly selected person in each household was interviewed at their home.
MAIN RESULTS—As predicted, higher SES men and women had higher levels of perceived overweight, monitored their weight more closely, and were more likely to be trying to lose weight. Higher SES groups also reported more restrictive dietary practices and more vigorous physical activity.
CONCLUSIONS—The results are consistent with the idea that part of the protection against weight gain in higher SES groups could be a higher frequency of weight monitoring, a lower threshold for defining themselves as overweight, and a greater likelihood of deliberate efforts at weight control.

2014-01-01

Background The study evaluates the effectiveness of Compelled Body Weight Shift (CBWS) approach in the rehabilitation of individuals with stroke. CBWS involves a forced shift of body weight towards a person’s affected side by means of a shoe insert that establishes a lift of the nonaffected lower extremity. Methods Eleven patients with acute stroke were randomly assigned to experimental and control groups. The experimental group received a two-week conventional physical therapy combined with CBWS and the control group received only a two-week conventional therapy. Weight bearing, Gait velocity, Berg’s Balance, and Fugl-Meyer’s Scores were recorded before and after the intervention. Results Weight bearing on the affected side increased in the experimental group and decreased in the control group. The increase in gait velocity with treatment was significant in both the groups (P < 0.05). However, experimental group (P = 0.01) demonstrated larger improvements in gait velocity compared to the control group (P = 0.002). Berg Balance and Fugl-Meyer scores increased for both the groups. Conclusion The implementation of a two-week intervention with CBWS resulted in the improvement in weight bearing and gait velocity of individuals with acute stroke. The present preliminary study suggests that CBWS technique could be implemented as an adjunct to conventional rehabilitation program for individuals with acute stroke. PMID:25530888

The portion size of food is a determinant of energy intake, linking with obese traits. A healthy plate for portion control has recently been made in a Japanese style. The aim of the current study was to assess the efficacy of a lifestyle intervention program using the Japanese-style healthy plate on weight reduction in overweight and obese diabetic Japanese subjects. We randomized overweight and obese diabetic subjects (n = 19, 10 women) into an intervention group including educational classes on lifestyle modification incorporating the healthy plate (n = 10) or a waiting-list control group (n = 9). The intervention period was three months, and the educational classes using the healthy plate were conducted monthly in a group session for the intervention group. The body weight, blood glycemic and metabolic measures, and psychosocial variables were measured at the baseline and after the 3-month intervention in both groups. The impression of the intervention was interviewed using a structured questionnaire. There was one drop-out in the control group. No adverse events were reported in the groups. Subjects in the intervention group had a greater weight change from baseline to the end of the 3-month intervention period (-3.7 +/- 2.5 [SD] kg in the intervention group vs. -0.1 +/- 1.4 kg in the control group, P = 0.002). Most subjects recorded that the use of a healthy plate could be recommended to other people. The lifestyle intervention program using the Japanese-style healthy plate, which was developed for portion control, may effectively reduce body weight in overweight and obese diabetic subjects in Japan. Further studies are needed to establish the efficacy of this methodology on weight management.

Weight-loss therapy to improve health in obese older adults is controversial because it causes further bone loss. Therefore, it is recommended that weight-loss therapy should include an intervention to minimize bone loss such as exercise training (ET). The purpose of this study was to determine the independent and combined effects of weight loss and ET on bone metabolism in relation to bone mineral density (BMD) in obese older adults. One-hundred-seven older (age >65 yrs) obese (BMI ≥30 kg/m2) adults were randomly assigned to a control group, diet group, exercise group, and diet-exercise group for 1 year. Body weight decreased in the diet (−9.6%) and diet-exercise (−9.4%) groups, not in the exercise (−1%) and control (−0.2%) groups (between-group P<.001). However, despite comparable weight loss, bone loss at the total hip was relatively less in the diet-exercise group (−1.1%) than in the diet group (−2.6%), whereas BMD increased in the exercise group (1.5%) (between-group P<.001) Serum C-terminal telopeptide (CTX) and osteocalcin concentrations increased in the diet group (31% and 24%) while they decreased in the exercise group (−13% and −15%) (between-group P<.001). In contrast, similar to the control group, serum CTX and osteocalcin concentrations did not change in the diet-exercise group. Serum procollagen propeptide concentrations decreased in the exercise group (−15%) compared with the diet group (9%) (P=.04). Serum leptin and estradiol concentrations decreased in the diet (−25% and −15%) and diet-exercise (−38% and −13%) groups, not in the exercise and control groups (between-group P=.001). Multivariate analyses revealed that changes in lean body mass (β=.33), serum osteocalcin (β= −.24), and 1-RM strength (β=.23) were independent predictors of changes in hip BMD (all P<.05). In conclusion, the addition of ET to weight-loss therapy among obese older adults prevents weight-loss-induced increase in bone turnover and attenuates weight-loss-induced reduction in hip BMD despite weight-loss-induced decrease in bone-active hormones.

The aim of the present study was to investigate the anti-obesity effects of Pereskia grandifolia leaf flour on rats fed a hypercaloric diet. After a hypercaloric diet for 10 weeks, 21 animals were divided into the following groups and were fed the following diets for 4 weeks: control (CH), hypercaloric diet with P. grandifolia flour (PGF) 5%, and hypercaloric diet with PGF 10%. Several measurements were performed including body weight, food consumption, body mass index, Lee index, liver weight, liver and body moisture content, and body and hepatic lipid level. Data were analyzed by Tukey's test at 5% probability. Rats fed PGF diet had decreased food consumption and body weight and showed lower body mass and Lee indices compared to control group. At week 2, weight of the PGF 10% group was statistically lower than the control group (CH). At week 4, the PGF 10% group demonstrated the highest body weight loss compared to the other two groups. There were no significant difference in total lipids and moisture level between the groups; however, rats fed PGF diet had lower hepatic lipids levels than control group and reduced liver weight. This suggests that PGF induced weight loss and decreased hepatic lipid level and may be effective in treating obesity and related metabolic diseases.

Background There is increasing evidence that obesity is related to asthma development and severity. However, it is largely unknown whether weight reduction can influence asthma management, especially in children. Objective To determine the effects of a multifactorial weight reduction intervention on asthma management in overweight/obese children with (a high risk of developing) asthma. Methods An 18-month weight-reduction randomized controlled trial was conducted in 87 children with overweight/obesity and asthma. Every six months, measurements of anthropometry, lung function, lifestyle parameters and inflammatory markers were assessed. Analyses were performed with linear mixed models for longitudinal analyses. Results After 18 months, the body mass index-standard deviation score decreased by -0.14±0.29 points (p<0.01) in the intervention group and -0.12±0.34 points (p<0.01) in the control group. This change over time did not differ between groups (p>0.05). Asthma features (including asthma control and asthma-related quality of life) and lung function indices (static and dynamic) improved significantly over time in both groups. The FVC% predicted improved over time by 10.1 ± 8.7% in the intervention group (p<0.001), which was significantly greater than the 6.1 ± 8.4% in the control group (p<0.05). Conclusions & clinical relevance Clinically relevant improvements in body weight, lung function and asthma features were found in both the intervention and control group, although some effects were more pronounced in the intervention group (FVC, asthma control, and quality of life). This implies that a weight reduction intervention could be clinically beneficial for children with asthma. Trial Registration ClinicalTrials.gov NCT00998413 PMID:27294869

In prevention stage, comparing with normal control group, triglycerides, blood sugar (BG), 24-hour urinary protein and cholesterol (CHO) were higher in T2DM group, but weight and urea nitrogen (BUN) was less in it. 24-hour urinary protein and cholesterol (CHO) were higher in T2DM group than the intervention group. 24-hour urinary protein and BG in the intervention group were higher than normal control group, but BUN is less than normal control group; In the intervention group the weight of kidney and weight of rat were also higher than T2DM group, but CHO and 24-hour urinary protein were less than T2DM group. The expression of TGF-β1 in T2DM group were more than the other groups. In treatment stage, serum creatinine (Cr), weight, BG and CHO, TGand 24-hour urinary protein quantitative were significantly higher in the DN rats than those in the normal control rats (P>0.05). The expression level of TGF-β1 and triglyceride level in the corn silk dihydroxycorn silk3 treated group were obviously lower than those in the DN rats.

The prevalence of overweight and obesity is on the increase the world over, which imposes an ever-increasing burden on societies and health care systems. This study sought to investigate the effect of motivational interviewing (MI) on a weight-loss program based on the protection motivation theory (PMT). This randomized clinical trial study, comprising pretest-posttest with a control group, was conducted on 150 overweight and obese women attending a private nutrition clinic for the first time. Samples were randomly selected using the clinic's records and then allocated to three groups (50 women in each group) receiving: 1) a standard weight-control program; 2) motivational interviewing; and 3) MI plus intention intervention. Data were collected using a researcher-made questionnaire through in-person interviews and were analyzed using SPSS (version 11) and statistical tests, including the Kruskal-Wallis test, one-way analysis of variance, paired t-test, and linear regression model. In the two intervention groups, the PMT construct scores, namely susceptibility (P = 0.001), severity (P = 0.001), rewards (P =0.004), self-efficacy (P = 0.001), response efficacy (P = 0.001), and costs (P = 0.014), were significantly increased compared to those in the control group. The anthropometric status was statistically significant in the MI group (P = 0.001) and the MI plus intention-intervention group (P = 0.001) at 2 months' follow-up, while in the control group, weight was meaningfully different after the intervention (P = 0.027). Weight was different between the groups after the intervention, with the Tukey test demonstrating that the differences were statistically significant between the control group and the MI group. Our results demonstrated that MI, combined with the implementation of intention intervention, increased weight loss and PMT construct scores in our study population.

Web-based treatment programs are attractive in primary care because of their ability to reach numerous individuals at low cost. Our aim of this meta-analysis is to systematically review the weight loss or maintenance effect of the Internet component in obesity treatment programs. MEDLINE and EMBASE literature searches were conducted to identify studies investigating the effect of Web-based individualized advice on lifestyle modification on weight loss. Randomized controlled trials that consisted of a Web-user experimental and non-Web user control group were included. Weight changes in the experimental group in comparison with the control group were pooled with a random-effects model. A total of 23 studies comprising 8697 participants were included. Overall, using the Internet had a modest but significant additional weight-loss effect compared with non-Web user control groups (-0.68 kg, P=0.03). In comparison with the control group, stratified analysis indicated that using the Internet as an adjunct to obesity care was effective (-1.00 kg, P<0.001), but that using it as a substitute for face-to-face support was unfavorable (+1.27 kg, P=0.01). An additional effect on weight control was observed when the aim of using the Internet was initial weight loss (-1.01 kg; P=0.03), but was not observed when the aim was weight maintenance (+0.68 kg; P=0.26). The relative effect was diminished with longer educational periods (P-trend=0.04) and was insignificant (-0.20 kg; P=0.75) in studies with educational periods of 12 months or more. The current meta-analysis indicates that the Internet component in obesity treatment programs has a modest effect on weight control. However, the effect was inconsistent, largely depending on the type of usage of the Internet or the period of its use.

Being overweight and obese are major risk factors for noncommunicable diseases such as cardiovascular diseases. The prevalence of overweight and obesity is high throughout the world and these issues are very serious in the Shunyi District in China. As mobile technologies have rapidly developed, mobile apps such as WeChat are well accepted and have the potential to improve health behaviors. This study aims to evaluate the effectiveness of a mobile app (WeChat) as an intervention on weight loss behavior. This study was conducted among an occupational population from August 2015 to February 2016 in the Shunyi District of Beijing. Before the intervention, the Shunyi District Government released an official document for weight loss to all 134 government agencies and enterprises in Shunyi District. Participants willing to use our official WeChat account were enrolled in a WeChat group and received 6 months of interventions for weight loss; those who were not willing to use the account were in a control group given routine publicity on weight loss. In total, 15,310 occupational participants including 3467 participants (22.65%) in the control group and 11,843 participants (77.35%) in the WeChat group were enrolled. Participants in the WeChat group lost more weight (mean 2.09, SD 3.43 kg) than people in the control group (mean 1.78, SD 2.96 kg), and the difference in mean weight loss between the two groups for males was significant based on the stratification of age and educational level. To control for confounding factors and to explore the effects of WeChat on weight loss, the propensity score method with a multinominal logistic regression was utilized. For males, this showed that the WeChat group (with both active and inactive subgroups) had a higher probability of maintaining weight, weight loss from 1 to 2 kg, or weight loss more than 2 kg than the control group. However, the control group had higher probability of weight loss from 0 to 1 kg. Being active in WeChat was likely to be associated with weight loss. The more active participants were in the weight loss program via WeChat, the more weight they lost. The weight loss intervention campaign based on an official WeChat account focused on an occupation-based population in Shunyi District was effective for males. The more active male participants were in using WeChat, the more weight they lost. There might be no effect or there may even be a negative effect on weight loss for females. Future research should focus on how to improve adherence to the WeChat weight loss interventions, to improve and refine the WeChat content such as developing a variety of materials to attract interest, and to protect personal privacy, especially for females. ©Chao He, Shiyan Wu, Yingying Zhao, Zheng Li, Yanyan Zhang, Jia Le, Lei Wang, Siyang Wan, Changqing Li, Yindong Li, Xinying Sun.

Background: Boric acid is widely used in biology, but its body weight reducing effect is not researched. Methods: Twenty mice were divided into two equal groups. Control group mice drank standard tap water, but study group mice drank 0.28mg/250ml boric acid added tap water over five days. Total body weight changes, major organ histopathology, blood biochemistry, urine and feces analyses were compared. Results: Study group mice lost body weight mean 28.1% but in control group no weight loss and also weight gained mean 0.09% (p<0.001). Total drinking water and urine outputs were not statistically different. Cholesterol, LDL, AST, ALT, LDH, amylase and urobilinogen levels were statistically significantly high in the study group. Other variables were not statistically different. No histopathologic differences were detected in evaluations of all resected major organs. Conclusion: Low dose oral boric acid intake cause serious body weight reduction. Blood and urine analyses support high glucose, lipid and middle protein catabolisms, but the mechanism is unclear.

This study aims to identify subgroups of consumers based on the health motives underlying their food choice in Western Balkan Countries. The survey (n = 2943) was based on the Food Choice Questionnaire (FCQ) and elicited information on socio-demographic characteristics, consumption frequency of healthy food products, nutrition knowledge and impulsiveness. Analysis of the FCQ data focused on items of "health and natural content" and "weight control" factors to identify clusters. The biggest group of the sample was weight control and health-concerned individuals (34 %), mainly urban women older than 50. The second group of respondents (31 %) was moderately motivated about health and weight. A third group was health concerned but paid less attention to weight control (21 %), mainly comprising men and people living with children. The last group consisted of unconcerned young men (14 %) eating less fruit and showing higher impulsiveness. Western Balkan consumers differ in the importance they attach to health and natural content and weight control. This insight is needed to target interventions.

Two groups of adult female rats were chronically centrifuged for 60 days (2.76 G, 4.15 G, controls at 1.00 G). Live weights of centrifugal rats decreased about 20 g (6%) per Delta 1 G above control. This weight loss comprised reductions in both body fat and fat-free body weight (FFBW) as determined by body-composition studies on eight rats per group killed at the end of centrifugation. Of nine components constituting the FFBW, only skeletal muscle, liver, and heart changed significantly in weight. Chemical composition showed reductions (compared with controls) in the fat fraction of most components and increases in the water fraction of liver and gut. Identical measurements were made on the remaining eight rats per group killed 43 days after return to 1 G. Neither centrifuged group had reached the control body-weight level at this time. No statistically significant effect of previous G level was found in any of the body-composition parameters. The possible involvment of physiological regulation was considered.

Nekvasil, N.; Baggio, C.

Pregnant and post-partum rats were given daily doses of 20% alcohol during days 13-21 gestation and postnatal days 3-12, respectively. Following exposure, all rat pups, were tested for balance, blood pressure, right and left cerebral hemisphere weights, and cerebellar weight. Results were grouped according to exposure and gender. The postnatal group was the only one to demonstrate difficulties with balance. The mean arterial pressure in males exposed postnatally was significantly lower than the control and prenatal males. Females exposed postnatally had a significantly higher blood pressure than control females. Within the postnatal group, males had a significantly lower blood pressuremore » than the females. Prenatal and control females differed significantly for left cerebral hemisphere (LCH) weight with the prenatal weighing less. Male pups exposed prenatally had significantly heavier LCH than the postnatal and control males. For both males and females, postnatal LCH weights did not differ from those of the control pups. Within the prenatal group, the LCH weight in females was significantly lower than in males. Mean cerebellar weights were significantly lower in postnatal animals compared to control animals. A major finding of this study is that the effect of alcohol exposure on rat pups depends on gender and developmental age.« less

This study tested a novel group-based, cognitive-behavioral intervention designed to reduce internalized weight stigma among individuals with obesity. A total of eight men and women with obesity who had experienced weight stigma and reported high levels of internalized weight stigma attended the Weight Bias Internalization and Stigma (BIAS) Program. The program provided eight weekly sessions of cognitive-behavioral treatment to cope with weight stigma. Participants completed questionnaires pre- and post-intervention, including the Weight Bias Internalization Scale (WBIS), Fat Phobia Scale, Weight Efficacy Life-Style Questionnaire (WEL), and Beck Depression Inventory-II (BDI-II). Six additional participants were included in a quasi-control group that received no intervention until after completing all study measures. Participants in the Weight BIAS Program reported significantly greater decreases in WBIS and Fat Phobia scores, and greater increases in WEL scores than participants in the quasi-control group (ps < .04). Changes in BDI-II scores did not differ between groups. Treatment-acceptability ratings were high among participants who received the intervention. Including cognitive-behavioral strategies to address weight stigma in weight management programs could potentially reduce internalized weight stigma and enhance treatment outcomes.

Consumption of sugar-sweetened beverages may cause excessive weight gain. We aimed to assess the effect on weight gain of an intervention that included the provision of noncaloric beverages at home for overweight and obese adolescents. We randomly assigned 224 overweight and obese adolescents who regularly consumed sugar-sweetened beverages to experimental and control groups. The experimental group received a 1-year intervention designed to decrease consumption of sugar-sweetened beverages, with follow-up for an additional year without intervention. We hypothesized that the experimental group would gain weight at a slower rate than the control group. Retention rates were 97% at 1 year and 93% at 2 years. Reported consumption of sugar-sweetened beverages was similar at baseline in the experimental and control groups (1.7 servings per day), declined to nearly 0 in the experimental group at 1 year, and remained lower in the experimental group than in the control group at 2 years. The primary outcome, the change in mean body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) at 2 years, did not differ significantly between the two groups (change in experimental group minus change in control group, -0.3; P=0.46). At 1 year, however, there were significant between-group differences for changes in BMI (-0.57, P=0.045) and weight (-1.9 kg, P=0.04). We found evidence of effect modification according to ethnic group at 1 year (P=0.04) and 2 years (P=0.01). In a prespecified analysis according to ethnic group, among Hispanic participants (27 in the experimental group and 19 in the control group), there was a significant between-group difference in the change in BMI at 1 year (-1.79, P=0.007) and 2 years (-2.35, P=0.01), but not among non-Hispanic participants (P>0.35 at years 1 and 2). The change in body fat as a percentage of total weight did not differ significantly between groups at 2 years (-0.5%, P=0.40). There were no adverse events related to study participation. Among overweight and obese adolescents, the increase in BMI was smaller in the experimental group than in the control group after a 1-year intervention designed to reduce consumption of sugar-sweetened beverages, but not at the 2-year follow-up (the prespecified primary outcome).

A trial was performed on a farm in the Coast Province of Kenya to study the effects of East Coast fever immunisation and different acaricidal treatments on the productivity of immunised and unimmunised beef cattle. Eighty cattle were immunised against Theileria parva parva (Marikebuni) by the infection and treatment method and a similar group was left as an unimmunised control. Immunisation had no deleterious effect on the cattle. After immunisation, the immunised and control groups were each subdivided into four groups of 20 and each subgroup was managed under a different tick control regimen. The tick control regimen were, acaricidal spraying twice a week or once every three weeks, the application of acaricide-impregnated ear-tags, and no tick control. During a nine-month exposure period there were 18 cases of East Coast fever among the 80 immunised cattle, three which were severe and the others mild. Among the 80 unimmunised cattle there were 57 cases of East Coast fever, 50 of which were severe. The highest morbidity and mortality occurred in the groups under limited tick control or without tick control. Overall weight gain in the immunised cattle, irrespective of the tick control regimen, was better than the weight gain in the unimmunised groups. Within the immunised groups, the weight gain of the cattle sprayed twice weekly was comparable to the weight gain of the animals with acaricidal ear-tags and was significantly higher than the weight gains in the groups sprayed once every three weeks or with tick control. Preliminary cost/benefit analysis showed that it was uneconomical to maintain unimmunised cattle under limited or no tick control.(ABSTRACT TRUNCATED AT 250 WORDS)

To investigate the effect of dietary weight loss on menstrual regularity in obese adolescent women with polycystic ovary syndrome (PCOS). A randomized controlled trial was held at the Faculty of Nursing, Mansoura University, and the Obesity Clinic of the Rheumatology Department at Mansoura University Hospitals between July 2011 and January 2013. Sixty adolescent women with PCOS, body mass index (BMI) greater than 30, and complaints of menstrual irregularities were included in this study. Enrolled women were divided equally and randomly into 2 groups: intervention and control groups. Women in the intervention group (n = 30) were subject to an intensive dietary educational program with instructions to follow a conventional energy restricted diet, whereas women in the control group were instructed to follow the same healthy diet of the first group without calorie restriction. Menstrual regularity, weight loss, the effect on waist circumference, and hirsutism score. The 2 groups were initially matched in average body weight, BMI, hirsutism score, and waist circumference. Six months later, there were significant decreases in all parameters in the weight reduction group. In addition, more menstrual episodes were recorded in the weight reduction compared with the control group (3.1 ± 1.2 vs. 2.3 ± 1.3; P = .010). Also, BMI, waist circumference, and hirsutism score were all significantly decreased at the end of the study. Dietary weight loss in adolescent women with PCOS resulted in significant improvement in menstrual regularity, BMI, waist circumference, and hirsutism score.

The purpose of this investigation was to assess the effectiveness of variable resistance as provided through elastic plus free weight techniques in college aged males and females. Twenty novice lifters were randomly assigned to a traditional free weight only (6 males and 5 females) or elastic band plus free weight group (5 males and 5 females) and 9 more normally active controls (5 males and 4 females), were recruited to maintain normal activity for the duration of the study. No differences existed between control, free weight and elastic band at baseline for age, body height, body mass, body mass index, and body fat percentage. One-repetition maximums were performed for squat and bench press while both strength and power were assessed using isokinetic dynamometry. Elastic groups and free-weight groups completed 24 weeks of whole body, periodized, high intensity resistance (65-95% of one-repetition maximum) training three times/week. Training programs were identical except that the elastic group trained the barbell squat, bench press and stiff-legged deadlift with 20-35% of their total prescribed training loads coming from band resistance (assessed at the top of the range of motion) with the remainder from free weight resistance. A mixed-model analysis revealed that peak torque, average power and one-repetition maximums for squat were significantly greater after training for the elastic group compared to the control (p<0.05). In addition, the free weight group also showed significantly greater improvements over the control in peak torque and one-repetition maximums for squat and bench press. No significant differences were observed between the elastic band and free weight groups. Combined variable elastic band plus free weight exercises are effective at increasing strength and power similar to free-weights alone in novice college aged males and females. However, due to complexity in set-up and load assignment elastic adoption by novice lifters in an unsupervised situation is not advised.

The objective was to compare weight loss and change in body composition in obese subjects with and without type 2 diabetes mellitus during a very-low-calorie diet (VLCD) program. Seventy weight-matched subjects with diabetes or normal fasting glucose (controls) participated in a 24-week VLCD study. Primary end points were changes in anthropometry, body composition, and fasting plasma insulin and β-hydroxybutyrate concentrations. Fifty-one subjects (24 with diabetes) completed the study. No difference in weight loss between the 2 groups at 24 weeks was found by intention-to-treat analysis. Both groups completing the study per protocol had near-identical weight change during the program, with similar weight loss at 24 weeks (diabetes: 8.5 ± 1.3 kg vs control: 9.4 ± 1.2 kg, P = .64). Change in fat mass index correlated with change in body mass index (BMI) in both groups (diabetes: r = 0.878, control: r = 0.920, both P < .001); but change in fat mass index per unit change in BMI was less in the diabetic group compared with controls (0.574 vs 0.905 decrease, P = .003), which persisted after adjusting for age, sex, and baseline BMI (P = .008). Insulin concentrations remained higher and peak β-hydroxybutyrate concentrations were lower in the diabetic compared with the control group. While following a 24-week VLCD program, obese subjects with and without diabetes achieved comparable weight loss; but the decrease in adiposity per unit weight loss was attenuated in diabetic subjects. Hyperinsulinemia may have inhibited lipolysis in the diabetic group; however, further investigation into other factors is needed. Copyright © 2012 Elsevier Inc. All rights reserved.

In this experiment, we used streptozotocin (STZ) to establish a model of gestational diabetes mellitus (GDM) rats, where Zuogui Wan was given to GDM rats. After pregnancy, offspring rats were divided into 4 groups: control group, high fat and sugar as the control group, GDM group, and Zuogui Wan GDM group. Rats in high fat and sugar as the control group, GDM group, and Zuogui Wan GDM group were fed with high fat and sugar diet. Rats in control group were fed the basic diet. The means of 2hPG were higher than 7.8 mmol·L−1 and lower than 11.1 mmol·L−1 on the rats of GDM group on week 15, and IGT models were successful. Body weight, abdominal fat weight, the ratio of abdominal fat weight and body weight, fasting plasma glucose, 2hPG, insulin, leptin, total cholesterol, and low density lipoprotein (LDL) of Zuogui Wan GDM group were significantly lower than GDM group. The level of adiponectin in Zuogui Wan GDM group was significantly higher than GDM group. And we concluded that giving Zuogui Wan to GDM rats can have a preventive effect on the offsprings' IGT induced by high fat and sugar diet. PMID:27034700

In the Philippines, researchers followed 135 babies born between August 1985-January 1986 to determine the effects of health education on infant health. Mothers in the experimental group learned about infant care, frequent nursing, personal hygiene, waiting until 4-6 months to begin supplementary foods, and the importance of the colostrum. Those in the control group received no such education. Both groups of mothers breast fed. 65% of the babies in the control group were healthy after 1 month, 48% after 4 months, 64% after 6 months, and 25% at 1 year while 57% of those from the experimental group were healthy after 1 month, 52% after 2 months, 3% after 5 months, and non at 1 year. There was a statistical difference in mean weights between the experimental and control groups at birth, 8 and 11 months. The average weights for babies in the experimental group were in the Class II category (weight for age 25th percentile and or = 50% percentile) while the average weight for those in the control group were in the Class I category (weight for age or = 25% percentile). Babies of multigravida mothers were more likely to be in Class III and IV (both classes 50th percentile) categories than those of primigravida mothers. No experimental group 5-7 month old babies had gastroenteritis while 6.1% 5 month olds, 16.1% 6 month olds, and 17.1% 7 months old in the control group had gastroenteritis. The incidence of respiratory infections was higher among control babies than experimental babies, except at 9 months. The incidence of fever was basically the same in both groups, except 9 and 12 month old experimental babies did not have any fever. Results of this study indicate that health education on infant health contributes to a lower incidence of gastroenteritis and respiratory infections and to higher weight gains.

Controversy exists regarding whether increasing dairy intake without energy restriction would lead to weight loss. We aimed to compare the potential weight-reducing effects of kefir drink (a probiotic dairy product) and milk in a dairy-rich non-energy-restricted diet in overweight or obese premenopausal women. One hundred and forty-four subjects were assessed for eligibility in this single-center, multi-arm, parallel-group, randomized controlled trial. Of these, seventy-five eligible women aged 25-45 years were randomly assigned to three groups, labeled as control, milk, and kefir, to receive an outpatient dietary regimen for 8 weeks. Subjects in the control group received a diet providing a maintenance level of energy intake, containing 2 servings/day of low-fat dairy products, while those in the milk and kefir groups received a weight maintenance diet, containing 2 additional servings/day (a total of 4 servings/day) of dairy products from low-fat milk or commercial kefir drink, respectively. Anthropometric outcomes including weight, body mass index (BMI), and waist circumference (WC) were measured every 2 weeks. Fifty-eight subjects completed the study. Using analysis of covariance models in the intention-to-treat population (n = 75), we found that at 8 weeks, subjects in the kefir and milk groups had significantly greater reductions in weight, BMI, and WC compared to those in the control group (all p < 0.01). However, no such significant differences were found between the kefir and milk groups. Kefir drink leads to a similar weight loss, compared with milk, in a dairy-rich non-energy-restricted diet in overweight or obese premenopausal women. However, further studies are warranted.

The National Weight Control Registry (NWCR) is the largest ongoing study of individuals successful at maintaining weight loss; the registry enrolls individuals maintaining a weight loss of at least 13.6 kg (30 lb) for a minimum of 1 year. The current report uses multivariate latent class cluster analysis to identify unique clusters of individuals within the NWCR that have distinct experiences, strategies, and attitudes with respect to weight loss and weight loss maintenance. The cluster analysis considers weight and health history, weight control behaviors and strategies, effort and satisfaction with maintaining weight, and psychological and demographic characteristics. The analysis includes 2,228 participants enrolled between 1998 and 2002. Cluster 1 (50.5%) represents a weight-stable, healthy, exercise conscious group who are very satisfied with their current weight. Cluster 2 (26.9%) has continuously struggled with weight since childhood; they rely on the greatest number of resources and strategies to lose and maintain weight, and report higher levels of stress and depression. Cluster 3 (12.7%) represents a group successful at weight reduction on the first attempt; they were least likely to be overweight as children, are maintaining the longest duration of weight loss, and report the least difficulty maintaining weight. Cluster 4 (9.9%) represents a group less likely to use exercise to control weight; they tend to be older, eat fewer meals, and report more health problems. Further exploration of the unique characteristics of these clusters could be useful for tailoring future weight loss and weight maintenance programs to the specific characteristics of an individual.

The process of atherosclerosis begins at early ages and is closely related to plasma lipid levels, specifically, an increase in low density lipoprotein (LDL), very low density lipoprotein (VLDL), and a decrease in high density lipoprotein (HDL). To determine if high birth weight, or macrosomia, is of predictive value for dyslipidemia in school children. A descriptive study with a case control design was conducted on two groups of children; one group of 140 children with a history of macrosomia, and another group of 100 children with normal weight at birth, born between January 1992 and December 1995. The aim was the early identification of atherosclerotic risk factors in school children with high weight at birth. Anthropometric variables and lipid profile were studied (cholesterol, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol, and triglycerides). There were significant differences between the mean weights of the two groups. There were no significant statistical differences between the two groups in the cholesterol levels (93.57% normal and 6.43% abnormal in the study group, and 90.00% normal and 10.00% abnormal in the control group), or in the values of HDL cholesterol. LDL cholesterol was abnormal in more children in the control group, and abnormal values of triglycerides were observed in 14.00% of cases in the study group 0.00% in the control group. High birth weight is not a predictive factor for hypercholesterolemia or HDL and LDL-cholesterol esters, but is positive for triglycerides in our study.

Acute and chronic toxicities of the water extract from calyces of Hibiscus sabdariffa were studied in male and female rats. After 14 days of a single oral administration of test substance 5,000 mg/kg body weight, measurement of the body and organ weights, necropsy and health monitoring were performed. No signs and differences of the weights or behaviour compared to the control rats were observed. The results indicated that the single oral administration of H. sabdariffa extract in the amount of 5,000 mg/kg body weight does not produce acute toxicity. The chronic toxicity was determined by oral feeding both male and female rats daily with the extract at the doses of 50, 100, and 200 mg/kg body weight for 270 days. The examinations of signs, animal behaviour and health monitoring showed no defects in the test groups compared to the control groups. Both test and control groups (day 270th) and satellite group (day 298th) were analysed by measuring their final body and organ weights, taking necropsy, and examining haematology, blood clinical chemistry, and microanatomy. Results showed no differences from the control groups. Overall, our study demonstrated that an oral administration of H. sabdariffa extract at the doses of 50, 100 and 200 mg/kg body weight for 270 days does not cause chronic toxicity in rat.

Obesity: locus of control, body image, weight loss, and age-at-onset.

In a retrospective investigation designed to measure locus of control, body image, and weight loss in Overeaters Anonymous members who had childhood, adolescence, or adulthood onset of obesity, 116 subjects were grouped according to age at onset of obesity and the year they joined OA. A convenience, volunteer sample of OA members completed a demographic data questionnaire, Rotter's Social Reaction. Inventory, and Secord and Jourard's Body Cathexis Scale. Significant overweight percentage differences were not found when the three age-at-onset groups were compared. Significant differences emerged, however, for adolescent-onset group persons who were categorized as "old" members; they had a larger weight loss and were more satisfied with their body image. A positive linear relationship between greater perception of internal control and a good body image was found in the entire adulthood-onset group. Weight loss and good body image of the oldest adolescent-onset group probably was the outcome of their association with a self-help group i.e., OA. Assessment of developmental issues related to the time of initial weight gain may indicate which treatment regime would be most effective.

To determine the effect of 7 days tactile kinesthetic stimulation (TKS) on preterm infants' weight and hospital stays in Khartoum State, Sudan. This is a quasi-experimental study, it was conducted in 4 hospitals between January and June 2013, Khartoum, Sudan, and it involved 160 preterm infants randomly assigned into the case and control groups (80 neonates in each). Preterm infants in the control group received routine nursing care, while preterm infants in the case group received TKS for 3 periods, 15 minute per day for 7 constitutive days, in addition to routine care. Data was collected using a structured self-designed and validated questionnaire, checklist, and weighting scale. Weight gain and hospital stay were compared between the 2 groups. Over the constitutive 7 days, the case group gained significantly more weight (1071 gm versus 1104 gm) compared with the control group (1077 gm versus 1084 gm) (1084.55±90.74) who gained only 6.9 gm within the same 7 days without TKS treatment. The mean difference in weight gain was significant (p=0.00). The hospital stay for preterm infants in the case group was significantly shorter (18.05±9.36 versus 25.47±10.25; p=0.00). Tactile kinesthetic stimulation for preterm infants has a beneficial effect on weight gain and earlier discharge from hospital, which are sequentially efficient and cost effective.

Objective. The effect of oral boric acid intake on reducing body weight has been previously demonstrated although the mechanism has been unclear. This research study reveals the mechanism. Subjects. Twelve mice were used, in groups of six each in the control and study groups. For five days, control group mice drank standard tap water while during the same time period the study group mice drank tap water which contains 0.28 mg/250 mL boric acid. After a 5-day period, gene expression levels for uncoupling proteins (UCPs) in the white adipose tissue (WAT), brown adipose tissue (BAT), and skeletal muscle tissue (SMT) and total body weight changes were analyzed. Results. Real time PCR analysis revealed no significant change in UCP3 expressions, but UCP2 in WAT (P: 0.0317), BAT (P: 0.014), and SMT (P: 0.0159) and UCP1 in BAT (P: 0.026) were overexpressed in the boric acid group. In addition, mice in the boric acid group lost body weight (mean 28.1%) while mice in the control group experienced no weight loss but a slight weight gain (mean 0.09%, P < 0.001). Conclusion. Oral boric acid intake causes overexpression of thermogenic proteins in the adipose and skeletal muscle tissues. Increasing thermogenesis through UCP protein pathway results in the accelerated lipolysis and body weight loss.

Weight-loss programmes for adults with type 2 diabetes are less effective in the long term owing to regain of weight. Our aim was to determine the 2 year effectiveness of a cognitive behavioural group therapy (group-CBT) programme in weight maintenance after diet-induced weight loss in overweight and obese adults with type 2 diabetes, using a randomised, parallel, non-blinded, pragmatic study design. We included 158 obese adults (median BMI 36.3 [IQR 32.5-40.0] kg/m 2 ) with type 2 diabetes from the outpatient diabetes clinic of Erasmus MC, the Netherlands, who achieved ≥5% weight loss on an 8 week very low calorie diet. Participants were randomised (stratified by weight loss) to usual care or usual care plus group-CBT (17 group sessions). The primary outcomes were the between-group differences after 2 years in: (1) body weight; and (2) weight regain. Secondary outcomes were HbA 1c levels, insulin dose, plasma lipid levels, depression, anxiety, self-esteem, quality of life, fatigue, physical activity, eating disorders and related cognitions. Data were analysed using linear mixed modelling. During the initial 8 week dieting phase, the control group (n = 75) lost a mean of 10.0 (95% CI 9.1, 10.9) kg and the intervention group (n = 83) lost 9.2 (95% CI 8.4, 10.0) kg (p = 0.206 for the between-group difference). During 2 years of follow-up, mean weight regain was 4.7 (95% CI 3.0, 6.3) kg for the control group and 4.0 (95% CI 2.3, 5.6) kg for the intervention group, with a between-group difference of -0.7 (95% CI -3.1, 1.6) kg (p = 0.6). The mean difference in body weight at 2 years was -1.2 (95% CI -7.7, 5.3) kg (p = 0.7). None of the secondary outcomes differed between the two groups. Despite increased treatment contact, a group-CBT programme for long-term weight maintenance after an initial ≥5% weight loss from dieting in obese individuals with type 2 diabetes was not superior to usual care alone.

Osteoarthritis causes severe pain and disability in joints, one of the most prevalent involved joints is the knee joint. There are several therapeutics ways to control pain and disability, but almost none of them are definite treatment. In this article, we tried to reveal the effect of weight loss on improving symptoms of knee osteoarthritis as an effective and permanent therapeutic approach. We chose 62 patients with grade 1-2 (mild to moderate) knee osteoarthritis and divided them equally into case and control groups. Patients should not had used NSAIDs at least for 6 months before study initiation. Symptoms severity was measured by WOMAC and VAS questionnaires before and after 3 months follow up. Weight and BMI were recorded too. Case group was suggested to have weight loss diet of less fat and carbohydrates and control group did not have any limitation. Comparison of variables' average of case and control groups was not logistically meaningful at the initiation and after the end of the study. But there was a meaningful correlation between variables' changes and lifestyle change in both groups, especially in WOMAC and VAS scores. All variables in case group had statistically meaningful differences between their amounts at the beginning and after the end of the study, on the contrary of the control group. In the comparison of our study with similar studies in the world. We deduced that weight loss can improve symptoms of knee osteoarthritis even in short time weight loss diet (3 months).

With technological advances in NICUs the survival rate of preterm infants has been increased. Because NICU environment is a potent source of stress for infants, its modification is an essential measure to decrease infants' morbidity. The purposes of this study were to compare the effects of wearing earmuff and provision silence for infants on their motor responses and gaining weight. In a randomized clinical trial 96 preterm infants were enrolled. Their motor responses were evaluated for two consecutive days in the morning and afternoon shifts, in the groups of earmuff and silence, and at similar time points in the control group. Also their weight was measured at days 1 and 10. In the two intervention groups, means of motor responses in infants were significantly less than in the control group, and weight gain of infants was more than the control group. However weight gain was more pronounced in the earmuff group. Both interventions led to decreasing number of motor responses and improvement of weight gain pattern, but these effects were more pronounced in earmuff group; thus because implementation of silence in NICUs has many barriers, it is suggested to use earmuff for preterm infants in these units. This trial obtained IRCT registration number IRCT2012092010812N2.

Being overweight and obese are significant health concerns for men and women, yet despite comparable needs for effective weight loss and maintenance strategies, little is known about the success of commercial weight loss programs in men. This study tests the hypothesis that men participating in a commercial weight loss program (Weight Watchers) had significantly greater weight loss than men receiving limited support from health professionals for weight loss (controls). A pooled analysis of weight loss and related physiologic parameter data from 2 randomized clinical trials was conducted. After 12 months, analysis of covariance tests showed that men in the commercial program group (n = 85) lost significantly more weight (P < .01) than men in the control group (n = 84); similar significant differences were observed for body mass index and waist circumference. These results suggest that participation in a commercial weight loss program may be a more effective means to lose weight and maintain weight loss. Published by Elsevier Inc.

To perform a cost comparison of a weight gain restriction programme for obese pregnant women with standard antenatal care, and to identify if there were differences in healthcare costs within the intervention group related to degree of gestational weight gain or degree of obesity at programme entry. A comparison of mean healthcare costs for participants of an intervention study at antenatal care clinics with controls in south-east Sweden. In total, 155 women in an intervention group attempted to restrict their gestational weight gain to <7 kg. The control group comprised 193 women. Mean costs during pregnancy, delivery and the neonatal period were compared with the costs of standard care. Costs were converted from Swedish Kronor to Euros (€). Healthcare costs during pregnancy were lower in the intervention group. There was no significant difference in total healthcare costs (i.e. sum of costs during pregnancy, delivery and the neonatal period) between the intervention group and the control group. Within the intervention group, the subgroup that gained 4.5-9.5 kg had the lowest costs. The total cost, including intervention costs, was € 1283 more per woman/infant in the intervention group compared with the control group (P=0.025). The degree of obesity at programme entry had no bearing on the outcome. The weight gain restriction programme for obese pregnant women was effective in restricting gestational weight gain to <7 kg, but had a higher total cost compared with standard antenatal care.

To study the effect of breast milk composition on weight growth velocity of infants fed with exclusive breast milk. One hundred and thirty-eight full-term singleton infants who received regular follow-up visits and fed with exclusive breast milk and their mothers were recruited. Body height, weight and head circumference of these infants were measured at regular visits. Z scores were used to evaluate growth velocity. The subjects were classified into a failure to thrive group (ΔZ scores≤-0.67), a poor growth group (-0.67<ΔZ scores<0) and a normal control group (ΔZ scores≥0). The samples of mature breast milk were collected for composition analysis. The differences in the levels of the protein, fats, energy, carbohydrates and minerals in breast milk were compared among the three groups. ΔZ scores for weight in the failure to thrive and poor growth groups were lower than in the normal control group (P<0.05). There was no significant difference in the levels of protein, fats and energy in breast milk among the failure to thrive, poor growth and normal control groups. However, the levels of carbohydrates and minerals in both the failure to thrive and poor growth groups were lower than in the normal control group (P<0.05). Weight growth velocity of infants can be affected by the composition of breast milk to a certain degree in a short period. In order to maintain a good weight growth velocity of infants, mothers should have a balanced diet to improve the quality of breast milk.

To compare the efficacy of different weight loss regimens on body weight loss and metabolic improvement in breast cancer survivors. Forty-eight obese breast cancer survivors were randomly divided into four groups and were followed for 1 year: 1) the Control group (subjects did not receive specific nutrition counseling); 2) the Weight Watchers group (subjects were given free coupons to attend weekly Weight Watchers meetings); 3) the Individualized group (a registered dietitian provided one-on-one nutritional counseling); and 4) the Comprehensive group (subjects received individualized dietary counseling and free coupons for the weekly Weight Watchers meetings). At baseline and 3-, 6-, and 12-month data collection visits, a fasting blood sample was obtained for assays. A three-day dietary record was kept during the week before these visits and dietary intake was analyzed. Subjects in the three intervention groups lost weight (Control: 1.1 +/- 1.7 kg; Weight Watchers: -2.7 +/- 2.1 kg; Individualized: -8.0 +/- 1.9 kg; Comprehensive: -9.5 +/- 2.7 kg) and percentage body fat, but only the Individualized and Comprehensive groups had significant losses. Subjects in the Comprehensive group showed the most improvement in cholesterol levels and had reductions in blood leptin levels. Because insulin resistance and high blood leptin levels are associated with breast cancer, losing weight to improve these parameters may reduce the risk of recurrence. Only subjects in the Comprehensive group showed significant reductions in body weight and fat, energy intake, and leptin levels. For breast cancer survivors, different weight loss strategies should be considered to assist them in losing weight.

Preventing weight gain in adults: the pound of prevention study.

Jeffery, R W; French, S A

1999-01-01

OBJECTIVES: This study examined whether weight gain with age could be prevented through the use of a low-intensity intervention. METHODS: Participants, 228 men and 998 women recruited from diverse sources, were randomized to one of the following groups: (1) no-contact control, (2) education through monthly newsletters, or (3) education plus incentives for participation. All participants were weighed and completed questionnaires about behaviors and attitudes related to weight at baseline and annually for 3 years thereafter. RESULTS: Individuals in intervention groups reported favorable changes over time in frequency of weighting and healthy dieting practices relative to those in the control group. These behavior changes were in turn related to a reduced rate of weight gain over time. However, weight gain over 3 years did not differ significantly by treatment group. CONCLUSIONS: This low-intensity educational approach to weight gain prevention sustained interest over a lengthy time period and was associated positively with behavior change, but it was not strong enough to significantly reduce weight gain with age.

Nonalcoholic fatty liver disease (NAFLD) is emerging as the most common liver disease. The only effective treatment is 7%-10% weight loss. Mobile technology is increasingly used in weight management. This study was performed to evaluate the effects of text messaging intervention on weight loss in patients with NAFLD. Thirty well-defined NAFLD patients (mean age 52 years, 67% females, mean BMI 38) were randomized 1:1 to control group: counselling on healthy diet and exercise, or intervention group: text messages in addition to healthy life style counselling. NAFLD text messaging program sent weekly messages for 22 weeks on healthy life style education. Primary outcome was change in weight. Secondary outcomes were changes in liver enzymes and lipid profile. Intervention group lost an average of 6.9 lbs. (P = .03) compared to gain of 1.8 lbs. in the control group (P = .45). Intervention group also showed a decrease in ALT level (-12.5 IU/L, P = .035) and improvement in serum triglycerides (-28 mg/dL, P = .048). There were no changes in the control group on serum ALT level (-6.1 IU/L, P = .46) and on serum triglycerides (-20.3 mg/dL P = .27). Using one-way analysis of variance, change in outcomes in intervention group compared to control group was significant for weight (P = .02) and BMI (P = .02). Text messaging on healthy life style is associated with reduction in weight in NAFLD patients. Larger studies are suggested to examine benefits on liver histology, and assess long-term impact of this approach in patients with NAFLD. © 2017 John Wiley & Sons A/S.

Compliance with weight reducing programs can be improved by intensive care and control. We tested a telemetrically-guided weight reduction program in overweight and obese persons. 200 outpatients (62 males) with a mean body mass index of 34 kg/m (2) and a mean age of 47 years participated in a prospective study for one year. During the first six months, telemetrical support (weight-transmission via Bluetooth (short range)-technology, 20-minutes telephone consultation with a nutritionist) was given weekly. After six months, participants were randomly assigned either to a group with further telemonitoring support (telemetric group) or to a group without contact to our clinic (control group). At baseline, and after six and twelve months, body weight, body composition (bioelectrical impedance analysis), and parameters of the metabolic syndrome were assessed at our clinic. 16 participants terminated the study prematurely during the first 6 months and 19 participants (10 from the telemetric group and 9 from the control group) during the second 6 months. According to the intention-to-treat principle, mean weight loss was 6.7 kg (p < 0,001), mean loss of body fat was 5.1 kg (p < 0,001), and mean loss of fat-free mass was 1.6 kg (p < 0,001) within the first six months. Moreover, metabolic and cardiovascular risk markers such as waist circumference, blood pressure, serum triglycerides and blood glucose declined significantly (p < 0,001). Prevalence of the metabolic syndrome fell from 49.5% to 42.0 % (p < 0,05). During the second six months body fat content, waist circumference, and blood glucose increased again in the control group but not in the telemetric group (p < 0,05-0,001). The telemetrically-guided weight loss program was a more efficacious measure than the less intensive support without telemonitoring.

Executive functioning (EF) problems may serve as vulnerability or maintenance factors for Binge-Eating Disorder (BED). However, it is unclear if EF problems observed in BED are related to overweight status or BED status. The current study extends this literature by examining EF in overweight and normal-weight BED compared to weight-matched controls. Participants were normal-weight women with BED (n = 23), overweight BED (n = 32), overweight healthy controls (n = 48), and normal-weight healthy controls (n = 29). The EF battery utilized tests from the National Institutes of Health (NIH) Toolbox and Delis-Kaplan Executive Function System (D-KEFS). After controlling for years of education and minority status, overweight individuals performed more poorly than normal-weight individuals on a task of cognitive flexibility requiring generativity (p < .01), and speed on psychomotor performance tasks (p = .01). Normal-weight and overweight BED performed worse on working memory tasks compared to controls (p = .04). Unexpectedly, normal-weight BED individuals out-performed all other groups on an inhibitory control task (p < .01). No significant differences were found between the four groups on tasks of planning. Regardless of weight status, BED is associated with working memory problems. Replication of the finding that normal-weight BED is associated with enhanced inhibitory control is needed. © 2017 Wiley Periodicals, Inc.

Context Extreme obesity is associated with health and cardiovascular disease risks. Although gastric bypass surgery induces rapid weight loss and ameliorates many of these risks in the short term, long-term outcomes are uncertain. Objective To examine the association of Roux-en-Y gastric bypass (RYGB) with weight loss, diabetes mellitus, and other health risks 6 years after surgery. Design, Setting, and Participants A prospective Utah-based study conducted between July 2000 and June 2011 of 1156 severely obese (body mass index [BMI] ≥35) participants aged 18–72 years (82% women; mean BMI 45.9; 95% CI, 31.2–60.6) who sought and received RYGB surgery (n=418), sought but did not have surgery (n=417; control group 1), or were randomly selected from a population-based sample not seeking weight loss surgery (n=321; control group 2). Main Outcome Measures Weight loss, diabetes, hypertension, dyslipidemia, and health-related quality of life were compared between participants having RYGB surgery and control participants using propensity score adjustment. Results Six years after surgery, patients who received RYGB surgery (with 92.6% follow-up) lost 27.7% (95% CI, 26.6%–28.9%) of their initial body weight compared with 0.2% (95% CI, -1.1% to 1.4%) gain in control group 1 and 0% (95% CI, −1.2 to 1.2%) in control group 2. Weight loss maintenance was superior in patients who received RYGB surgery, with 94% (95% CI, 92%–96%) and 76% (95% CI, 72%–81%) of patients receiving RYGB surgery maintaining at least 20% weight loss 2 and 6 years after surgery, respectively. Diabetes remission rates 6 years after surgery were 62% (95% CI, 49%–75%) in the RYGB surgery group, 8% (95% CI, 0%–16%) in control group 1, and 6% (95% CI, 0%–13%) in control group 2, with remission odds ratios (ORs) of 16.5 (95% CI, 4.7–57.6; P<.001) vs control group 1 and 21.5 (95% CI, 5.4–85.6; P<.001) vs control group 2. The incidence of diabetes throughout the course of the study was reduced after RYGB surgery (2%; 95% CI, 0%–4%; versus 17%; 95% CI, 10%–24%; OR, 0.11; 95% CI, 0.04–0.34 compared with control group 1 and 15%; 95% CI, 9%–21%; OR, 0.21; 95% CI, 0.06–0.67 compared with control group 2; both P<.001). The numbers of participants with bariatric surgery-related hospitalizations were 33 (7.9%), 13 (3.9%), and 6 (2.0%) for RYGB surgery group and 2 control groups, respectively. Conclusion Among severely obese patients, compared with nonsurgical control patients, the use of RYGB surgery was associated with higher rates of diabetes remission and lower risk of cardiovascular and other health outcomes over 6 years.

Smoking cessation often results in weight gain which discourages many smokers from quitting and can increase health risks. Treatments to reduce cessation-related weight gain have been tested in highly controlled trials of in-person treatment, but have never been tested in a real-world setting, which has inhibited dissemination. The Best Quit Study (BQS) is a replication and "real world" translation using telephone delivery of a prior in-person efficacy trial. randomized control trial in a quitline setting. Eligible smokers (n = 2540) were randomized to the standard 5-call quitline intervention or quitline plus simultaneous or sequential weight management. Regression analyses tested effectiveness of treatments on self-reported smoking abstinence and weight change at 6 and 12 months. Study enrollees were from 10 commercial employer groups and three state quitlines. Participants were between ages 18-72, 65.8% female, 68.2% white; 23.0% Medicaid-insured, and 76.3% overweight/obese. The follow-up response rate was lower in the simultaneous group than the control group at 6 months (p = 0.01). While a completers analysis of 30-day point prevalence abstinence detected no differences among groups at 6 or 12 months, multiply imputed abstinence showed quit rate differences at 6 months for:simultaneous (40.3%) vs. sequential (48.3%), p = 0.034 and simultaneous vs. control (44.9%), p = 0.043. At 12 months, multiply imputed abstinence, was significantly lower for the simultaneous group (40.7%) vs. control (46.0%), p < 0.05 and vs. sequential (46.3%), p < 0.05. Weight gain at 6 and 12 months was minimal and not different among treatment groups. The sequential group completed fewer total calls (3.75) vs. control (4.16) and vs. simultaneous group (3.83), p = 0.01, and fewer weight calls (0.94) than simultaneous (2.33), p < 0.0001. The number of calls completed predicted 30-day abstinence, p < 0.001, but not weight outcomes. This study offers a model for evaluating population-level public health interventions conducted in partnership with tobacco quitlines. Simultaneous (vs. sequential) delivery of phone/web weight management with cessation treatment in the quitline setting may adversely affect quit rate. Neither a simultaneous nor sequential approach to addressing weight produced any benefit on suppressing weight gain. This study highlights the need and the challenges of testing intensive interventions in real-world settings. ClinicalTrials.gov Identifier: NCT01867983 . Registered: May 30, 2013.

Objective This analysis focuses on 1-year maternal and infant follow-up of a randomized trial that tested a weight management intervention conducted during pregnancy. Methods We randomly assigned 114 women with obesity (mean BMI 36.7 kg/m2) at a mean of 15 weeks’ gestation to a weight management intervention or usual care control condition. The intervention ended at delivery and resulted in less gestational weight gain and a lower proportion of large-for-gestational age newborns among intervention compared to control participants. The primary outcome at 12 months postpartum was maternal weight. Secondary outcomes included infant weight-for-age and weight-for-length z-scores. Results At 1 year, mothers in the intervention group weighed 96.3±18.6 kg, and in the control group, 99.7±19.2 kg. There was no significant difference between groups in change in weight from randomization to 1-year postpartum (b=-0.47, 95% CI [-4.03, 3.08]. There was a significant main effect of group for infant weight-for-age z-score (b=-0.40, 95% CI [-0.75,-0.05]) but not infant weight-for-length z-scores (b=-0.20, 95% CI [-0.59,0.20]. Conclusions A gestational weight management intervention did not influence maternal weight or infant weight-for-length at 1-year postpartum. Future studies may be warranted to determine if extending prenatal interventions into the postpartum period would be beneficial for maternal and infant outcomes. PMID:27670399

Changes in body weight and food choice in those attempting smoking cessation: a cluster randomised controlled trial

PubMed Central

2012-01-01

Background Fear of weight gain is a barrier to smoking cessation and significant cause of relapse for many people. The provision of nutritional advice as part of a smoking cessation programme may assist some in smoking cessation and perhaps limit weight gain. The aim of this study was to determine the effect of a structured programme of dietary advice on weight change and food choice, in adults attempting smoking cessation. Methods Cluster randomised controlled design. Classes randomised to intervention commenced a 24-week intervention, focussed on improving food choice and minimising weight gain. Classes randomised to control received “usual care”. Results Twenty-seven classes in Greater Glasgow were randomised between January and August 2008. Analysis, including those who continued to smoke, showed that actual weight gain and percentage weight gain was similar in both groups. Examination of data for those successful at giving up smoking showed greater mean weight gain in intervention subjects (3.9 (SD 3.1) vs. 2.7 (SD 3.7) kg). Between group differences were not significant (p = 0.23, 95% CI −0.9 to 3.5). In comparison to baseline improved consumption of fruit and vegetables and breakfast cereal were reported in the intervention group. A higher percentage of control participants continued smoking (74% vs. 66%). Conclusions The intervention was not successful at minimising weight gain in comparison to control but was successful in facilitating some sustained improvements in the dietary habits of intervention participants. Improved quit rates in the intervention group suggest that continued contact with advisors may have reduced anxieties regarding weight gain and encouraged cessation despite weight gain. Research should continue in this area as evidence suggests that the negative effects of obesity could outweigh the health benefits achieved through reductions in smoking prevalence.

High-technology medical care of extremely low-birth-weight (ELBW) infants (< 1001 g) involves repeated medical interventions which are potentially painful and may later affect reaction to pain. At 18 months corrected age (CCA), we examined parent ratings of pain sensitivity and how pain sensitivity ratings related to child temperament and parenting style in 2 groups of ELBW children (49 with a birth weight of 480-800 g and 75 with a birth weight of 801-1000 g) and 2 control groups (42 heavier preterm (1500-2499 g) and 29 full-birth-weight (FBW) children (> 2500 g). Both groups of ELBW toddlers were rated by parents as significantly lower in pain sensitivity compared with both control groups. The relationships between child temperament and pain sensitivity rating varied systematically across the groups. Temperament was strongly related to rated pain sensitivity in the FBW group, moderately related in the heavier preterm and ELBW 801-1000 g groups, and not related in the lowest birth-weight group (< 801 g). Parental style did not mediate ratings of pain sensitivity. The results suggest that parents perceive differences in pain behavior of ELBW toddlers compared with heavier preterm and FBW toddlers, especially for those less than 801 g. Longitudinal research into the development of pain behavior for infants who experience lengthy hospitalization is warranted.

Mice were fed with source water (SW) and tap water (TW) for 90 d to evaluate hepatotoxicity induced by the drinking water. Histopathologic observation showed no obvious damage to hepatic tissue in the SW and TW groups. However, microarray analysis indicated that the SW and TW exposures affected many metabolic pathways, among which PPAR (peroxisome proliferator-activated receptors) signaling was most susceptible. Immunohistochemical staining demonstrated that both PPAR-α and PPAR-γ were significantly increased in the exposure groups compared to control. Enzyme-linked immunosorbent assay revealed that PPAR-α expression level was increased from 23.37±0.53 ng g(-1) liver weight in control group to 26.60±1.43 ng g(-1) liver weight in SW group and 27.68±1.10 ng g(-1) liver weight in TW group (p<0.05). For PPAR-γ, the expression level was also significantly enhanced from 0.83±0.07 ng g(-1) liver weight in control group to 1.11±0.20 ng g(-1) liver weight in SW group and 1.16±0.07 ng g(-1) liver weight in TW group (p<0.05). The SW and DW posed no obvious hepatotoxicity on mice and PPAR-α/-γ could be used as a novel biomarker to assess public health risk induced by slightly contaminated drinking water.

Summary Background The prevalence of male obesity is increasing but few men take part in weight loss programmes. We assessed the effect of a weight loss and healthy living programme on weight loss in football (soccer) fans. Methods We did a two-group, pragmatic, randomised controlled trial of 747 male football fans aged 35–65 years with a body-mass index (BMI) of 28 kg/m2 or higher from 13 Scottish professional football clubs. Participants were randomly assigned with SAS (version 9·2, block size 2–9) in a 1:1 ratio, stratified by club, to a weight loss programme delivered by community coaching staff in 12 sessions held every week. The intervention group started a weight loss programme within 3 weeks, and the comparison group were put on a 12 month waiting list. All participants received a weight management booklet. Primary outcome was mean difference in weight loss between groups at 12 months, expressed as absolute weight and a percentage of their baseline weight. Primary outcome assessment was masked. Analyses were based on intention to treat. The trial is registered with Current Controlled Trials, number ISRCTN32677491. Findings 374 men were allocated to the intervention group and 374 to the comparison group. 333 (89%) of the intervention group and 355 (95%) of the comparison group completed 12 month assessments. At 12 months the mean difference in weight loss between groups, adjusted for baseline weight and club, was 4·94 kg (95% CI 3·95–5·94) and percentage weight loss, similarly adjusted, was 4·36% (3·64–5·08), both in favour of the intervention (p<0·0001). Eight serious adverse events were reported, five in the intervention group (lost consciousness due to drugs for pre-existing angina, gallbladder removal, hospital admission with suspected heart attack, ruptured gut, and ruptured Achilles tendon) and three in the comparison group (transient ischaemic attack, and two deaths). Of these, two adverse events were reported as related to participation in the programme (gallbladder removal and ruptured Achilles tendon). Interpretation The FFIT programme can help a large proportion of men to lose a clinically important amount of weight; it offers one effective strategy to challenge male obesity. PMID:24457205

Jeng, Hueiwang Anna; Yu, Liang

2008-06-01

The objective of this study was to assess whether polycyclic aromatic hydrocarbons (PAHs) affect male reproductive functions in vivo. Male reproductive parameters included testis weight, sperm counts and motility, circulating follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone. The average body weight, testis weight, and epididymis weight in the exposed group were not significantly lower than that in the control group (p < 0.01). The daily numbers of sperm in the PAH-exposed groups were significantly lower than those in the control group. The motility of sperm in the PAH-exposed groups was significantly less than those in the control group. Plasma LH concentrations increased at the end of the exposure period and continued to increase after post-cessation of exposure to PAHs. Testosterone decreased at the end of the exposure period and increased after post-cessation of exposure. However, the follicle-stimulation hormone level remained relatively stable during the study period. The present study showed that PAHs can compromise sperm functions and alter endocrine hormone levels.

Using ovariectomized rats as the model of postmenopausal osteoporosis, the effect of SXGTC on inorganic element content of femur and femoral ash weight of the model rats were surveyed. Animals were divided into model group, SXGTC high dose group, SXGTC low dose group, positive control group (treated with Gushukang) and normal control group. The medication began at one week after operation and lasting for 120 days. The contents of inorganic elements, including Ca, P, Mg, Zn, Cu and Mn in the three medicated groups were higher than those of the model group (P < 0.01). The effect of SXGTC was dose dependent. The difference between the SXGTC groups and the positive control group was insignificant. The femoral ash weight of the SXGTC high dose group and the positive control group was significantly higher than that of the model group (P < 0.01). SXGTC could antagonize the rat's bony change caused by ovariectomy to increase the inorganic contents in bone, which may, in grneral, lead to a bone-strengthening effect.

BACKGROUND Consumption of sugar-sweetened beverages may cause excessive weight gain. We aimed to assess the effect on weight gain of an intervention that included the provision of noncaloric beverages at home for overweight and obese adolescents. METHODS We randomly assigned 224 overweight and obese adolescents who regularly consumed sugar-sweetened beverages to experimental and control groups. The experimental group received a 1-year intervention designed to decrease consumption of sugar-sweetened beverages, with follow-up for an additional year without intervention. We hypothesized that the experimental group would gain weight at a slower rate than the control group. RESULTS Retention rates were 97% at 1 year and 93% at 2 years. Reported consumption of sugar-sweetened beverages was similar at baseline in the experimental and control groups (1.7 servings per day), declined to nearly 0 in the experimental group at 1 year, and remained lower in the experimental group than in the control group at 2 years. The primary outcome, the change in mean body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) at 2 years, did not differ significantly between the two groups (change in experimental group minus change in control group, −0.3; P = 0.46). At 1 year, however, there were significant between-group differences for changes in BMI (−0.57, P = 0.045) and weight (−1.9 kg, P = 0.04). We found evidence of effect modification according to ethnic group at 1 year (P = 0.04) and 2 years (P = 0.01). In a prespecified analysis according to ethnic group, among Hispanic participants (27 in the experimental group and 19 in the control group), there was a significant between-group difference in the change in BMI at 1 year (−1.79, P = 0.007) and 2 years (−2.35, P = 0.01), but not among non-Hispanic participants (P>0.35 at years 1 and 2). The change in body fat as a percentage of total weight did not differ significantly between groups at 2 years (−0.5%, P = 0.40). There were no adverse events related to study participation. CONCLUSIONS Among overweight and obese adolescents, the increase in BMI was smaller in the experimental group than in the control group after a 1-year intervention designed to reduce consumption of sugar-sweetened beverages, but not at the 2-year follow-up (the prespecified primary outcome).

[Purpose] To assess the effects of sensorimotor foot stimulation on the symmetry of weight distribution on the feet of patients in the chronic post-stroke phase. [Subjects and Methods] This study was a prospective, single blind, randomized controlled trial. In the study we examined patients with chronic stroke (post-stroke duration > 1 year). They were randomly allocated to the study group (n=8) or to the control group (n=12). Both groups completed a standard six-week rehabilitation programme. In the study group, the standard rehabilitation programme was supplemented with sensorimotor foot stimulation training. Each patient underwent two assessments of symmetry of weight distribution on the lower extremities with and without visual control, on a treadmill, with stabilometry measurements, and under static conditions. [Results] Only the study group demonstrated a significant increase in the weight placed on the leg directly affected by stroke, and a reduction in asymmetry of weight-bearing on the lower extremities. [Conclusion] Sensorimotor stimulation of the feet enhanced of weight bearing on the foot on the side of the body directly affected by stroke, and a decreased asymmetry of weight distribution on the lower extremities of patients in the chronic post-stroke phase.

Kangaroo mother care (KMC) is associated with positive neonatal outcomes. Studies demonstrated significant influence of maternal factors on the success of applying KMC. To determine maternal factors that influence on anthropometric parameters in low birth weight babies that received kangaroo mother care. This is a randomized controlled study that involved low birth weight newborns. We randomly assigned newborns into two groups; a group who received KMC and a group who received conventional care. Maternal factors were recorded. We followed weight, length, and head circumferences of newborns for thirty days. A total of 40 newborns were included. Weight parameters were significantly higher in the KMC group than the conventional group. From maternal characteristics, only gestational age was found to influence increased head circumference in KMC group (p = 0.035); however, it did not affect the increase in weight or length. Maternal age, parity, education, mode of delivery, fetal sex, and initial Apgar score did not influence growth parameters in either groups. KMC was associated with increased weight gain in LBW infants. Gestational age influences head growth in infants who received KMC.

The aim of the study was to examine whether weight reduction can result in improvement of fibromyalgia impact questionnaire (FIQ) in the patients with fibromyalgia syndrome (FMS). This study was a randomized controlled trial. Obese patients with fibromyalgia were randomly assigned to 6-month dietary weight loss (n = 41) and no weight loss (n = 42) groups. Patients were assessed at baseline and at 6 months. The primary outcome measure was FIQ. Secondary measures included the tender point (TP) examination, Beck Depression Inventory-II, and Pittsburg Sleep Quality Index. Compared to the control group, patients who underwent weight reduction obtained significantly better FIQ (p = 0.007), lower mean TP count (p = 0.015), and lower mean TP pain rating in the lower body (p < 0.001). Patients who lost weight had less depression and better sleep quality than the controls. Patients who lost weight had significantly lower interleukin 6 and C-reactive protein levels than those in the control group (p = 0.034 and p = 0.007, respectively). Weight loss in obese patients with FMS leads to significant improvement in the quality of life as shown by the decrease in the FIQ score. Depression, sleep quality, and tender point count are also significantly improved by weight loss in obese patients with fibromyalgia. Our results suggest that weight reduction should be a part of fibromyalgia treatment.

This study was designed to evaluate the effectiveness of the compelled body weight shift (CBWS) therapy approach in the rehabilitation of individuals with chronic stroke. CBWS involves a forced shift of body weight toward a person's affected side by means of a shoe insert that establishes a lift of the nonaffected lower extremity. Eighteen individuals with chronic, unilateral stroke (mean age 57.7 ± 11.9 years, with a range of 35-75 years; mean time since stroke 6.7 ± 3.9 years, with a range of 1.1-14.1 years) who showed asymmetrical stance were randomly divided into 2 groups: the experimental group received 6 weeks of physical therapy combined with CBWS therapy, and the control group received only physical therapy. Both groups underwent a battery of identical tests (Fugl-Meyer Assessment, Berg Balance Scale, weight bearing, and gait velocity) before the start of the rehabilitation intervention, following its completion, and 3 months after the end of therapy. After the intervention, weight bearing on the affected side (measured with the Balance Master) increased in the experimental group to a larger degree compared to the control group (9.7% vs 6.4%). Similarly, gait velocity increased 10.5% in the experimental group compared to the control group. Improvements in weight bearing and gait velocity were maintained in the experimental group after the 3-month retention period. The study outcome revealed that a 6-week intervention involving CBWS therapy could result in a long-lasting improvement of the symmetry of weight bearing and velocity of gait in individuals with chronic stroke.

To examine psychiatric morbidity and overall functioning in adults born with low birth weight compared with normal birth weight controls at age 26 years and to study longitudinal trajectories of psychiatric morbidity from early adolescence to adulthood. Prospective cohort study wherein 44 preterm very low birth weight (≤1500 g), 64 term small for gestational age (SGA; <10th percentile), and 81 control adults were examined using the MINI-International Neuropsychiatric Interview: M.I.N.I. Plus, Norwegian version, the Global Assessment of Functioning, and questions on daily occupation and level of education. Prevalence of psychiatric disorders from previous follow-ups at age 14 and 19 years were included for longitudinal analysis. From adolescence to adulthood, the term SGA group had a marked increase in the estimated probability of psychiatric disorders from 9% (95% confidence interval, 4-19) to 39% (95% confidence interval, 28-51). At 26 years, psychiatric diagnoses were significantly more prevalent in the preterm very low birth weight group (n = 16, 36%; P = .003) and the term SGA group (n = 24, 38%; P = .019) compared with the control group (n = 11, 14%). Both low birth weight groups had lower educational level and functioning scores than controls and a higher frequency of unemployment and disability benefit. Low birth weight was a substantial risk factor for adult psychiatric morbidity and lowered overall functioning. The results underscore the need for long-term follow-up of low birth weight survivors through adolescence and adulthood, focusing on mental health. The longitudinal increase in psychiatric morbidity in the term SGA group calls for additional investigation. Copyright © 2017 by the American Academy of Pediatrics.

To determine the effects of a low-fat plant-based diet program on anthropometric and biochemical measures in a multicenter corporate setting. Employees from 10 sites of a major US company with body mass index ≥ 25 kg/m(2) and/or previous diagnosis of type 2 diabetes were randomized to either follow a low-fat vegan diet, with weekly group support and work cafeteria options available, or make no diet changes for 18 weeks. Dietary intake, body weight, plasma lipid concentrations, blood pressure and glycated hemoglobin (HbA1C) were determined at baseline and 18 weeks. Mean body weight fell 2.9 kg and 0.06 kg in the intervention and control groups, respectively (P<0.001). Total and low-density lipoprotein (LDL) cholesterol fell 8.0 and 8.1 mg/dl in the intervention group and 0.01 and 0.9 mg/dl in the control group (P<0.01). HbA1C fell 0.6 percentage point and 0.08 percentage point in the intervention and control group, respectively (P<0.01).Among study completers, mean changes in body weight were -4.3 kg and -0.08 kg in the intervention and control groups, respectively (P<0.001). Total and LDL cholesterol fell 13.7 and 13.0 mg/dl in the intervention group and 1.3 and 1.7 mg/dl in the control group (P<0.001). HbA1C levels decreased 0.7 percentage point and 0.1 percentage point in the intervention and control group, respectively (P<0.01). An 18-week dietary intervention using a low-fat plant-based diet in a corporate setting improves body weight, plasma lipids, and, in individuals with diabetes, glycemic control.

To evaluate the short-term impact of portion-controlled food provision in combination with an Internet behavioral weight loss program on weight, blood cholesterol, and blood glucose levels. Fifty participants, mean age 46 ± 10.7 years and mean body mass index 35.1 ± 3.8 kg/m2 , were randomized to one of two study groups, an Internet behavioral weight loss program (Internet-alone; n = 25) or an Internet behavioral weight loss program plus a commercially available portion-controlled diet (Internet + PCD; n = 25) for 12 weeks. An intent-to-treat analysis found that the mean weight change in the Internet + PCD group was -5.7 ± 5.6 kg and in the Internet-alone group (n = 25) was -4.1 ± 4.0 kg (P = 0.26). Participants in the Internet + PCD group achieved significantly greater improvements in blood glucose (-2.6 ± 5.7 vs. 1.4 ± 11.0 mg/dl; P = 0.05) and LDL cholesterol (-8.2 ± 18.0 vs. -0.6 ± 21.0 mg/dl; P = 0.04), compared with Internet-alone group. These data suggest that there may be short-term clinical benefit in using a PCD in conjunction with a behavioral Internet-based weight loss program to enhance weight loss and improve health indicators.

There is a paucity of evidence on the heterogeneous impacts of financial incentives on weight loss. Between March 2010 and January 2012, in a randomized controlled trial, we assigned 700 obese persons to three experimental arms. We test whether particular subgroups react differently to financial incentives for weight loss. Two treatment groups obtained a cash reward (€150 and €300 with 237 and 229 participants, respectively) for achieving an individually-assigned target weight within four months; the control group (234 participants) was not incentivized. Participants and administrators were not blinded to the intervention. We find that monetary rewards effectively induced obese individuals to reduce weight across all subgroups. However, there is no evidence for treatment-effect heterogeneity for those groups that were incentivized. Among those who were in the €300 group, statistically significant and large weight losses were observed for women, singles, and those who are not working (all above 4 kg in four months). In addition, the magnitude of the reward matters only for women and migrants. The effectiveness of financial incentives to reduce weight nevertheless raises sensitive ethical issues that should be taken into consideration by policymakers. Copyright © 2015 Elsevier Ltd.

More publications support the statement that maternal periodontitis may be a risk factor of preterm delivery and low birth-weight, than the number of those that suggest opposing evidence. The proving or rejecting of the questionable relationship may be carried out--among other methods--by analyzing the results of interventional studies. The aim of our study was to investigate whether or not it is possible to decrease the chance of preterm birth and low birth-weight in the case of healthy non-smoking women through the elimination of periodontal inflammation by providing professional oral hygiene treatment during pregnancy. After periodontal examination 80 pregnant women received professional oral hygiene treatment including plaque and calculus removal, root planing, motivation and instruction (treatment group); only the periodontal status was recorded in 79 cases (control group). The mean length of pregnancy and birth-weight in the treatment group were compared with similar data of the control group. Data were assessed using statistical methods. The mean weight of newborns was 3005.3 grams in the treatment group, while 2644.2 grams in the control group (p < 0.0001). The delivery occurred later in the treatment group (37.0 week), than among the control group (36.4 week), although the difference was not significant (p = 0.059). In the periodontal treated group, which had a statistically suitable number of members, the periodontal treatment might have contributed to a more optimal date of delivery and to achieving a larger birth-weight.

Background Web-based programs are a potential medium for supporting weight loss because of their accessibility and wide reach. Research is warranted to determine the shorter- and longer-term effects of these programs in relation to weight loss and other health outcomes. Objective The aim was to evaluate the effects of a Web-based component of a weight loss service (Imperative Health) in an overweight/obese population at risk of cardiovascular disease (CVD) using a randomized controlled design and a true control group. Methods A total of 65 overweight/obese adults at high risk of CVD were randomly allocated to 1 of 2 groups. Group 1 (n=32) was provided with the Web-based program, which supported positive dietary and physical activity changes and assisted in managing weight. Group 2 continued with their usual self-care (n=33). Assessments were conducted face-to-face. The primary outcome was between-group change in weight at 3 months. Secondary outcomes included between-group change in anthropometric measurements, blood pressure, lipid measurements, physical activity, and energy intake at 3, 6, and 12 months. Interviews were conducted to explore participants’ views of the Web-based program. Results Retention rates for the intervention and control groups at 3 months were 78% (25/32) vs 97% (32/33), at 6 months were 66% (21/32) vs 94% (31/33), and at 12 months were 53% (17/32) vs 88% (29/33). Intention-to-treat analysis, using baseline observation carried forward imputation method, revealed that the intervention group lost more weight relative to the control group at 3 months (mean –3.41, 95% CI –4.70 to –2.13 kg vs mean –0.52, 95% CI –1.55 to 0.52 kg, P<.001), at 6 months (mean –3.47, 95% CI –4.95 to –1.98 kg vs mean –0.81, 95% CI –2.23 to 0.61 kg, P=.02), but not at 12 months (mean –2.38, 95% CI –3.48 to –0.97 kg vs mean –1.80, 95% CI –3.15 to –0.44 kg, P=.77). More intervention group participants lost ≥5% of their baseline body weight at 3 months (34%, 11/32 vs 3%, 1/33, P<.001) and 6 months (41%, 13/32 vs 18%, 6/33, P=.047), but not at 12 months (22%, 7/32 vs 21%, 7/33, P=.95) versus control group. The intervention group showed improvements in total cholesterol, triglycerides, and adopted more positive dietary and physical activity behaviors for up to 3 months verus control; however, these improvements were not sustained. Conclusions Although the intervention group had high attrition levels, this study provides evidence that this Web-based program can be used to initiate clinically relevant weight loss and lower CVD risk up to 3-6 months based on the proportion of intervention group participants losing ≥5% of their body weight versus control group. It also highlights a need for augmenting Web-based programs with further interventions, such as in-person support to enhance engagement and maintain these changes.

The objective of this pilot 6-month randomized controlled trial was to determine the effectiveness of an intensive, community-based, group intervention that focused on diet, physical activity, and peer support for reducing weight among urban-dwelling African Americans with comorbid type 2 diabetes and hypertension. Sixty-one participants were randomized into an intervention or control group. The 6-month intervention consisted of 18 group sessions led by a dietitian in a community setting and weekly telephone calls from a peer supporter. The intervention featured culturally tailored nutrition education, behavioral skills training, and social support focused on changes to diet and physical activity. The control group consisted of two 3-hour group sessions of diabetes self-management education taught by a community health worker. Outcome measures were assessed at baseline and 6 months. The primary outcome was achievement of a 5% weight reduction at 6 months. A secondary outcome was achievement of a 0.5 percentage-point reduction in hemoglobin A1c (HbA1c). Groups did not differ in achievement of the weight-loss goal. Intervention participants lost a mean of 2.8 kg (P = .01); control participants did not lose a significant amount of weight. A greater proportion of intervention (50.0%) than control (21.4%) participants reduced HbA1c by 0.5 percentage points or more at 6 months (P = .03). The intervention was more effective than usual care (short-term diabetes education) at improving glycemic control, but not weight, in low-income African Americans with comorbid diabetes and hypertension. A community-based 6-month group class with culturally tailored education, behavioral skills training, and peer support can lead to a clinically significant reduction in HbA1c.

Objective Examine the effect of weekday exposure over six months to different lunch sizes on energy intake and body weight in a free-living sample of working adults. Design and Methods Adults (n=233) were randomly assigned to one of three lunch size groups (400 kcal; 800 kcal; 1600 kcal) or to a no-free lunch control group for six months. Weight and energy intake were measured at baseline, and months 1, 3, and 6. Results Lunch energy was significantly higher in the 800 and 1600 kcal groups compared to the 400 kcal group (p < 0.0001). Total energy was significantly higher for the 1600 kcal group compared to the 400 and 800 kcal groups (p = 0.02). Body weight change at six months did not significantly differ at the 5% level by experimental group (1600 kcal group: +1.1 kg (sd=0.44); 800 kcal group: −0.1 kg (sd=0.42); 400 kcal group: −0.1 kg (sd=0.43); control group: 1.1 (sd=0.42); p=.07). Weight gain over time was significant in the 1600 kcal box lunch group (p < 0.05). Conclusions Weekday exposure for six months to a 1600 kcal lunch caused significant increases in total energy intake and weight gain. PMID:24510841

To assess the effectiveness of a range of weight management programmes in terms of weight loss. Eight arm randomised controlled trial. Primary care trust in Birmingham, England. 740 obese or overweight men and women with a comorbid disorder identified from general practice records. Weight loss programmes of 12 weeks' duration: Weight Watchers; Slimming World; Rosemary Conley; group based, dietetics led programme; general practice one to one counselling; pharmacy led one to one counselling; choice of any of the six programmes. The comparator group was provided with 12 vouchers enabling free entrance to a local leisure (fitness) centre. The primary outcome was weight loss at programme end (12 weeks). Secondary outcomes were weight loss at one year, self reported physical activity, and percentage weight loss at programme end and one year. Follow-up data were available for 658 (88.9%) participants at programme end and 522 (70.5%) at one year. All programmes achieved significant weight loss from baseline to programme end (range 1.37 kg (general practice) to 4.43 kg (Weight Watchers)), and all except general practice and pharmacy provision resulted in significant weight loss at one year. At one year, only the Weight Watchers group had significantly greater weight loss than did the comparator group (2.5 (95% confidence interval 0.8 to 4.2) kg greater loss,). The commercial programmes achieved significantly greater weight loss than did the primary care programmes at programme end (mean difference 2.3 (1.3 to 3.4) kg). The primary care programmes were the most costly to provide. Participants allocated to the choice arm did not have better outcomes than those randomly allocated to a programme. Commercially provided weight management services are more effective and cheaper than primary care based services led by specially trained staff, which are ineffective.

To evaluate whether premature infants who received an exclusive human milk (HM)-based diet and a HM-derived cream supplement (cream) would have weight gain (g/kg/d) at least as good as infants receiving a standard feeding regimen (control). In a prospective noninferiority, randomized, unmasked study, infants with a birth weight 750-1250 g were randomly assigned to the control or cream group. The control group received mother's own milk or donor HM with donor HM-derived fortifier. The cream group received a HM-derived cream supplement if the energy density of the HM tested <20 kcal/oz using a near infrared HM analyzer. Infants were continued on the protocol until 36 weeks postmenstrual age. Primary outcomes included growth velocities and amount of donor HM-derived fortifier used. The hypothesis of noninferiority was established if the lower bound of the one-sided 95% CI for the difference in weight velocities exceeded -3 g/kg/day. There were no differences between groups in baseline demographics for the 78 infants studied except racial distribution (P = .02). The cream group (n = 39) had superior weight (14.0 ± 2.5 vs 12.4 ± 3.0 g/kg/d, P = .03) and length (1.03 ± 0.33 vs 0.83 ± 0.41 cm/wk, P = .02) velocity compared with the control group (n = 39). There were no significant differences in amount of fortifier used between study groups. The 1-sided 95% lower bound of the CI for the difference in mean velocity (cream-control) was 0.38 g/kg/d. Premature infants who received HM-derived cream to fortified HM had improved weight and length velocity compared with the control group. HM-derived cream should be considered an adjunctive supplement to an exclusive HM-based diet to improve growth rates in premature infants. Copyright © 2014 The Authors. Published by Elsevier Inc.

Objectives: This study aimed to examine the effectiveness of an Islamic voluntary fasting intervention to control post-Ramadan weight gain. Methods: This study was conducted between July and November 2011. Two weight loss intervention programmes were developed and implemented among groups of overweight or obese Malay women living in the Malaysian cities of Putrajaya and Seremban: a standard programme promoting control of food intake according to national dietary guidelines (group B) and a faith-based programme promoting voluntary fasting in addition to the standard programme (group A). Participants’ dietary practices (i.e., voluntary fasting practices, frequency of fruit/vegetable consumption per week and quantity of carbohydrates/protein consumed per day), body mass index (BMI), blood pressure, fasting blood high-density lipoprotein cholesterol (HDL-C) and total cholesterol (TC):HDL-C ratio were assessed before Ramadan and three months post-Ramadan. Results: Voluntary fasting practices increased only in group A (P <0.01). Additionally, the quantity of protein/carbohydrates consumed per day, mean diastolic pressure and TC:HDL-C ratio decreased only in group A (P <0.01, 0.05, 0.02 and <0.01, respectively). Frequency of fruit/vegetable consumption per week, as well as HDL-C levels, increased only in group A (P = 0.03 and <0.01, respectively). Although changes in BMI between the groups was not significant (P = 0.08), BMI decrease among participants in group A was significant (P <0.01). Conclusion: Control of post-Ramadan weight gain was more evident in the faith-based intervention group. Healthcare providers should consider faith-based interventions to encourage weight loss during Ramadan and to prevent post-Ramadan weight gain among patients. PMID:25685394

Functional brain response to food images in successful adolescent weight losers compared with normal-weight and overweight controls.

PubMed

Jensen, Chad D; Kirwan, C Brock

2015-03-01

Research conducted with adults suggests that successful weight losers demonstrate greater activation in brain regions associated with executive control in response to viewing high-energy foods. No previous studies have examined these associations in adolescents. Functional neuroimaging was used to assess brain response to food images among groups of overweight (OW), normal-weight (NW), and successful weight-losing (SWL) adolescents. Eleven SWL, 12 NW, and 11 OW participants underwent functional magnetic resonance imaging while viewing images of high- and low-energy foods. When viewing high-energy food images, SWLs demonstrated greater activation in the dorsolateral prefrontal cortex (DLPFC) compared with OW and NW controls. Compared with NW and SWL groups, OW individuals demonstrated greater activation in the ventral striatum and anterior cingulate in response to food images. Adolescent SWLs demonstrated greater neural activation in the DLPFC compared with OW/NW controls when viewing high-energy food stimuli, which may indicate enhanced executive control. OW individuals' brain responses to food stimuli may indicate greater reward incentive processes than either SWL or NW groups. © 2015 The Obesity Society.

The purpose of the present study was to examine the interactions between weight perceptions, weight control behaviours and body fatness in a multiethnic sample of adolescent girls. A cross-sectional study. Girls from European (37.7 %), Pacific Island (21.6 %), East Asian (15.8 %), Maori (10.2 %) and South Asian (9.6 %) populations and from other ethnicities (5.0 %). A sample of 954 girls aged 11-15 years participated in the study. BMI was derived from height and weight, whereas body fat (BF) was determined from hand-to-foot bioimpedance measurements. Weight perceptions, weight control behaviours and pubertal stage were assessed by questionnaire. Body size and fatness varied significantly across ethnic groups. Although few differences in weight perceptions were observed between BMI and %BF percentile groups, a relatively high degree of weight misclassification was evident across all BF categories. The number of girls trying to lose weight exceeded those who perceived themselves as being overweight, with the magnitude of the difference dependent on ethnicity. Of the girls trying to lose weight, the combination of dieting and exercise was the most common weight loss practice; however, a substantial proportion reported neither exercise nor dieting. Weight status perception was a stronger predictor of weight loss intent than actual BF when controlling for all other factors. Interventions and educational campaigns that assist girls in recognising a state of excess BF are a priority for all ethnic groups to increase the likelihood that behavioural changes necessary to combat widespread overweight and obesity are adopted.

Preoperative nutritional counseling provides an opportunity to ameliorate patients' clinical condition and build-up adequate habits and perception of competence. Study aimed to evaluate: (a) the effect of INDIVIDUO on weight and metabolic control; (b) the impact of INDIVIDUO on psychosocial variables associated with successful weight-control. Two-arms randomised controlled single-site study, with six-month duration. Patients were recruited from an Obesity Treatment Unit's waiting list. For the intervention group (IG), an operating procedure manual was used, nutritionists received training/supervision regarding INDIVIDUO's procedures. Control group (CG) received health literacy-promoting intervention. Intention-to-treat and per-control analysis were used. Outcomes included weight, metabolic control variables (blood pressure, glycemia, insulinemia, triglycerides, cholesterol), measures of eating and physical activity patterns, hedonic hunger, autonomous/controlled regulation, perceived competence for diet (PCS-diet) and quality of life. Primary outcomes were weight and metabolic control. Effect size was estimated by odds ratio and Cohens'd coefficient. Overall, 94 patients participated (IG:45; CG:49) and 60 completed the study (IG:29; CG:31). Intervention patients lost an excess 9.68% body weight (%EWL), vs. 0.51% for CG. Adjusting for age and baseline BMI, allocation group remained an independent predictor of %EWL (B=8.43, 95%CI: 2.79-14.06). IG had a six-fold higher probability (OR: 6.35, 95%CI: 1.28-31.56) of having adequate/controlled fasting glycemia at final evaluation. PCS-diet at final evaluation was independently predicted by baseline PCS-diet (B=0.31, 95%CI: 0.06-0.64), variation in autonomous regulation (B=0.43, 95%CI: 0.15-0.71) and allocation group (B=0.26, 95%CI: 0.04-1.36). Results on weight and metabolic control support INDIVIDUO as a valuable clinical tool for obesity surgery candidates counseling. Additionally, intervention associated with perceived competence for weight-control behaviours and autonomous regulation. Copyright © 2016 Asia Oceania Association for the Study of Obesity.

Objectives: To investigate body image and psychosocial adjustment among competitive bodybuilders, non-competitive weight trainers, and athletically active men. Methods: Participants were 40 men in each of the three groups who were assessed on body composition and multiple facets of body image evaluation, investment and anxiety, eating attitudes, and social self esteem. Results: Relative to the other two groups, competitive bodybuilders had greater body mass due to fat-free body mass. Although groups did not differ in their situational body image discomfort, competitive bodybuilders and weight trainers had a more positive global appearance evaluation and were more psychologically invested in their physical appearance. Compared with active controls, men in both weightlifting groups were more satisfied with their upper torso and muscle tone. Competitive bodybuilders reported more mid torso satisfaction than the other two groups. Competitive bodybuilders also wished to be significantly heavier than controls did and reported higher social self esteem but greater eating disturbance. Conclusions: The findings suggest that competitive bodybuilders as a group are not more "muscle dysmorphic" than either non-competitive weight trainers or physically active men who do not train with weights.

Aim: The aim of this study was the assessment of various levels of date palm kernel (DPK) on the growth performance of broilers. Materials and Methods: A 250-day-old broiler chicks were randomly selected and categorized into five groups (50 chicks/group) contained A (control), B, C, D and E fed with 0%, 1%, 2%, 3% and 4% levels of DPK in balanced ration, respectively, for 6 weeks. Feed and water intake were recorded daily in the morning and evening. The data for feed intake, water intake, live body weight, and feed conversion ratio (FCR) were recorded from all birds regularly. The carcass weight and percentage obtained via six slaughtered birds were randomly selected from each group. Finally, economic aspects of the rations evaluated. Results: The most feed intakes of broilers were recorded in Group A (3915.1 g) that was significantly higher than Groups D and E. The highest water intake was in Group E (9067.78 ml) that was significantly higher than Group A and control group. Live body weight was highest in Group E (979.85 g) than Groups B, C, and control group. The best growth weights were determined significantly in Groups D (1921.96 g) and E (1935.95 g). The lowest FCRs were indicated significantly in Groups D (1.97 g/g) and E (1.92 g/g) than Groups B and A. The highest carcass weights were recorded in Groups D (1214.01 g) and E (1230.88 g) that were significantly more than other groups. Dressing percentages in Groups D (61.76%) and E (62.17%) were higher than other groups (p<0.05). The net profits (Rs.) in Groups A, B, C, D and E were indicated 27.01, 32.77, 36.78, 43.47 and 44.51 per broiler, respectively. Conclusion: It was concluded that the high levels of DPK (3-4%) significantly decreased broiler feed intake and increased water intake, live body weight, growth weight, carcass weight, dressing percentage, net profit per bird and also had positive effects on growth of broilers.

Objective To evaluate the effectiveness of the Fuel Your Life program, an adaptation of the Diabetes Prevention Program, utilizing implementation strategies commonly used in worksite programs – telephone coaching, small group coaching and self-study. Methods The primary outcomes of BMI and weight were examined in a randomized control trial conducted with city/county employees. Results Although the majority of participants in all three groups lost some weight, the phone group lost significantly more weight (4.9 lbs.), followed by the small groups (3.4 lbs.) and the self-study (2.7 lbs.). Of the total participants, 28.3% of the phone group, 20.6% of the small group and 15.7 of the self-study group lost 5% or more of their body weight. Conclusions Fuel Your Life (DPP) can be effectively disseminated using different implementation strategies that are tailored to the workplace. PMID:27820761

Intermittent, reversible intraabdominal vagal blockade (VBLOC® Therapy) demonstrated clinically important weight loss in feasibility trials. EMPOWER, a randomized, double-blind, prospective, controlled trial was conducted in USA and Australia. Five hundred three subjects were enrolled at 15 centers. After informed consent, 294 subjects were implanted with the vagal blocking system and randomized to the treated (n = 192) or control (n = 102) group. Main outcome measures were percent excess weight loss (percent EWL) at 12 months and serious adverse events. Subjects controlled duration of therapy using an external power source; therapy involved a programmed algorithm of electrical energy delivered to the subdiaphragmatic vagal nerves to inhibit afferent/efferent vagal transmission. Devices in both groups performed regular, low-energy safety checks. Data are mean ± SEM. Study subjects consisted of 90 % females, body mass index of 41 ± 1 kg/m(2), and age of 46 ± 1 years. Device-related complications occurred in 3 % of subjects. There was no mortality. 12-month percent EWL was 17 ± 2 % for the treated and 16 ± 2 % for the control group. Weight loss was related linearly to hours of device use; treated and controls with ≥ 12 h/day use achieved 30 ± 4 and 22 ± 8 % EWL, respectively. VBLOC® therapy to treat morbid obesity was safe, but weight loss was not greater in treated compared to controls; clinically important weight loss, however, was related to hours of device use. Post-study analysis suggested that the system electrical safety checks (low charge delivered via the system for electrical impedance, safety, and diagnostic checks) may have contributed to weight loss in the control group.

Childhood obesity is one of the most critical public health problems in the world. It is associated with low neuromuscular function and postural deformities. Whether weight loss can improve postural stability and neuromuscular control, benefit daily activities, or prevent injury is unknown. Therefore, this study attempts to investigate the effect of a 6 month weight management program on postural stability and neuromuscular control among obese children. We will conduct a prospective, single-blind, randomized controlled trial with 120 prepubescent obese children. Participants will be randomly assigned to a weight management group or a control group. The weight management group will participate in a dietary and exercise program. The control group will receive health education. After the intervention, participants will be followed for 6 months with no active intervention. The primary and secondary outcomes will be assessed at the baseline, and after 6 months and 12 months. Primary outcome measures will include body weight, body height, body mass index, waist circumference, hip circumference, and body fat percentage. Secondary outcome measures will include three-dimensional functional biomechanics in different tasks, proprioception tests of the knee and ankle, neuromuscular response of the leg muscles, and muscle strength tests of the knee and ankle. Furthermore, adverse events will be recorded and analyzed. An intention-to-treat analysis will be performed if any participants withdraw from the trial. The important features of this trial include the randomization procedures and large sample size. This study attempts to estimate the effect of weight loss intervention on outcomes, including daily life function, postural stability, and neuromuscular control in prepubescent obese children. Therefore, our results can be useful for obese children, medical staff, and healthcare decision makers. Chinese Clinical Trial Registry ChiCTR-IOB-15005874.

This pilot study compared weight loss and serum indicators of coronary artery disease (CAD) risk between 2 weight loss (energy-deficit) diets, one controlled for carbohydrate as a percentage of total calories and the other controlled for fat as percentage of total calories. Participants were randomized to 1 of 2 diets and fed on an outpatient basis for 70 days, after which they followed their diets using their own resources for an additional 70 days. Energy deficit for the diets was determined by indirect calorimetry with a 500- to 750-calorie per day adjustment. Weight and CAD risk indicators and serum lipid and C-reactive protein levels were measured at baseline, day 70, and day 140. The study was completed by 16 of 20 participants who were able to comply with the feeding portion of the study as well as with follow-up appointments during the second (self-management) period of the study. Participants lost weight in both diet groups (24.4 lbs, carbohydrate controlled; 18.5 lbs, fat controlled), and serum CAD risk factors decreased in both groups. There were no significant differences in CAD risk factors between diet groups, although there was a trend toward lighter low-density lipoprotein (LDL) size in the carbohydrate-controlled group. During the self-management portion of the study, weight loss stalled or regained from loss during the previous feeding period. The results, although underpowered, are consistent with recent studies in which macronutrient ratio of total calories in diet did not affect degree of weight loss and in which carbohydrate-controlled diets produced a predominance of lighter LDLs.

Aim To determine the effect of a diet and exercise intervention in pregnant women on total gestational weight gain, weekly weight gain, 42-days postpartum weight retention, mode of delivery, and infant birth weight. One hundred and one eligible Chinese pregnant women whose pre-pregnancy body mass index ranged from 18.5 to 24.9 were recruited between June 2013 and June 2014 from a tertiary hospital. Ninety participants, 45 in each group, completed the study. Intervention women received three face-to-face interventions and three follow-up phone calls which were developed based on the Transtheoretical Model. Gestational weight was measured at each prenatal check. Mode of delivery and infant birth weight were collected from the medical record. The 42-days postpartum weight was measured during the postpartum visits. (1) The total gestational weight gain and mean weight gain per week in the intervention group were significantly less than the control group (P=0.045 and P=0.008 respectively). (2) Infant birth weight was significantly lower in the intervention group (P=0.012). (3) Postpartum weight retention was significantly less in the intervention group (P=0.001). 4) There were not significant differences in mode of delivery. 5) Infant birth weight was significantly less than the control group (P=0.012). The lifestyle intervention significantly reduced gestational weight gain, optimized infant weight and lowered postpartum weight retention. Promotion of gestational weight management is needed and cultural health beliefs about pregnancy and postpartum practices should be considered when developing the intervention plan.

Feeding behavior control and dietetics with consequent weight reduction can be the most efficacious and fundamental methods to normalize fasting blood glucose. However, pioglitazone treatment has been found to incrementally increase body weight. In this study, we investigated whether the combined application of a 5-HT(2A) receptor antagonist, sarpogrelate, with pioglitazone can provide a clinical benefit. Diabetic male KK-A(y) mice were randomly assigned to four groups: those receiving 10 mg/kg/day pioglitazone treatment for 30 days (pioglitazone group, n = 7), those receiving 30 mg/kg/day sarpogrelate treatment for 30 days (sarpogrelate group, n = 7), those receiving both agents for 30 days (pioglitazone + sarpogrelate group, n = 7) and those receiving no treatment (control group, n = 7). Feed intake was lower in the pioglitazone + sarpogrelate group than in the pioglitazone group. Water intake was also significantly lower in the pioglitazone, sarpogrelate and pioglitazone + sarpogrelate groups than in the control group. Combined application (pioglitazone + sarpogrelate) resulted in a 176% increase in leptin concentration compared with vehicle control. Body weight was significantly higher in the pioglitazone group, and there was a trend toward a smaller increment in body weight in the pioglitazone + sarpogrelate group. Mean values, calculated by multiplying insulin concentration and nonfasting glucose concentration, were significantly lower in the pioglitazone + sarpogrelate group than in the control group. These results suggest that the combined application of sarpogrelate with pioglitazone provides therapeutic benefits not only in preventing adverse effects but also in the treatment of diabetes.

This study sought to examine the effectiveness of sibutramine, a weight loss agent, on clozapine-associated weight gain. This was a 12-week double-blind, placebo controlled, randomized trial of sibutramine for weight loss in obese clozapine-treated schizophrenia or schizoaffective disorder subjects. Ten patients were enrolled into the placebo group and 11 patients into the sibutramine group. There were no significant baseline differences between the two groups on age, gender, education, ethnicity, diagnosis, weight, body mass index (BMI), and blood pressure. At week 12, there were no significant differences in changes in weight, BMI, abdominal and waist circumferences, Hba1c, fasting glucose, or cholesterol levels. Sibutramine treatment did not show significant weight loss compared with placebo in clozapine-treated patients with schizophrenia or schizoaffective disorder. Further research with a larger sample size and longer follow-up duration is warranted.

The comparative effects of chronic [28 days] consumption of kola nut and its active constituent, caffeine diets on locomotor behaviour and body weights in mice were investigated. Thirty adult Swiss white mice [15-30 g body weight], were used for the study. The open field-maze was employed for the evaluation of locomotor behaviour. Mice in the control group [n=10] were fed normal rodent chow, mice in the kola nut-fed group [n=10] were fed kola diet [25 % wt/wt of rodent chow] while those in the caffeine-fed group [n=10] were fed caffeine diet [0.66% wt/wt of rodent chow] for 4 weeks. All animals were allowed free access to clean drinking water. Daily food intake, water intake and body weight change were also measured. Daily food intake in the kola nut and caffeine-fed group of mice was significantly [P<0.001 respectively] lower than the control. There was also a significant [P<0.001] decrease in daily water intake in the caffeine-fed group compared to the control whereas, the apparent decrease of water intake in the kola nut-fed group was not significantly different from the control. Body weight change was also significantly [P<0.001 and P<0.05 respectively] lower in the kola nut and caffeine-fed groups of mice when compared to the control. The frequency of rearing in the open field was significantly [P<0.01] lower in the caffeine-fed group of mice when compared to the control. The frequency of grooming was also significantly [P<0.05] lower in the caffeine-fed group of mice when compared to the control. There was also a significant [P<0.05] decrease in the frequency of light-dark transitions in the light/dark transition box for the caffeine-fed group when compared to the control. The results showed that chronic consumption of kola nut and caffeine diets caused decrease in food intake and body weight. Consumption of caffeine-diet also significantly decreased water intake and locomotor activity. The effect of kola nut-diets on water intake and locomotor activity was not significant. Hence, the effect of kola nut on locomotor behaviour and water intake may not be due to caffeine only.

Lessons learned about primary weight maintenance and secondary weight maintenance: results from a qualitative study.

Obesity is now a worldwide problem and Ireland is no exception with approximately two thirds of the adult population now overweight or obese. A recent report has found that 53% of Irish adults aged 50 years and over are classified as centrally obese and at substantially increased risk of metabolic complications. While most studies investigating weight maintenance have been conducted on those who have managed to lose weight and/or achieved weight loss maintenance (secondary weight maintainers), few studies have been undertaken to understand the attitudes, behaviours, motivations and strategies of those who maintain their weight within normal weight ranges over their lifetime, so called primary weight maintainers. This study aims to explore this issue through qualitative exploration of primary weight maintainers in an Irish University. Seven focus groups were conducted (including three single interviews) with 17 participants in total across three different groups, 1) primary weight maintainers, 2) secondary weight maintainers, and 3) those unable to sustain or achieve weight loss. The interviews were transcribed and thematic analysis was applied to interpret the findings. After analyzing the participant's interviews, planning and organization or lack of, emerged as themes across the three groups in varying degrees. Strategizing, perseverance and willpower were seen as integral to weight maintenance and weight loss in groups one and two, these were lacking in group three. Prioritizing exercise and perseverance in maintaining a high level of activity was evident in groups one and two and was lacking in group three. Motivational influences were equal across the groups however, group three found it difficult to turn this into action. Group one had behavioural control of calorie intake maintaining a balance between week and weekend eating. Group three found it difficult to control calorie intake and portion size. Self-image differed across the three groups with cognitive dissonance evident amongst those in group three. This study showed that there are many factors that influence primary weight maintenance. Considering that we live in a society that is predominantly sedentary, predominantly overweight and with poor food choice options facing us every day, fighting our way through to ensure healthy weight maintenance requires active, conscious efforts. The factors identified in this study which are important in healthy weight maintenance are all potentially modifiable with life-coach, nutrition, exercise and cognitive interventions particularly if peer support and a whole family approach are incorporated.

To determine the effects of dairy calcium on changes in body weight and body fat mass in obese women on a weight-loss diet. The non-randomised controlled study was conducted at Sivas Government Hospital, Turkey, between January and March 2010, and comprised obese women outpatients coming to the Nutrition and Diet Clinic. The participants were assigned to three groups according to their intake of dairy products as control, low dairy and high dairy groups. Measurements of anthropometry, blood pressure and analysis of blood chemistry were done before and after the intervention. The mean age of the 65 women was 33.10±6.18 years. There were 20(30.7%) women in control group, 22(33.8%) in high dairy group and 23(35.3%) in low dairy group. At the end of the study, body weight, body mass index, waist and hip circumferences, waist/hip ratio, body fat percentage, and fat mass significantly decreased within the groups (p<0.001) whereas no difference was determined between the groups. Plasma total cholesterol levels decreased (p<0.05, p<0.001) and high-density lipoprotein cholesterol levels increased (p<0.05) in the two intervention groups. Systolic blood pressure was negatively correlated with dairy calcium (?=0.460, p<0.05). In women following a weight-loss programme, increasing the amount of dairy products was not effective in improving weight-loss compared to calorie restriction alone.

Evidence from various epidemiological studies and experimental animal studies has linked adverse intrauterine circumstances with health problems in adult life. This field of investigation is known as Developmental Origins of Health and Disease (DOHaD). Studies investigating the relation between developing polycystic ovary syndrome (PCOS) in adulthood and birth weight have yielded inconsistent results: PCOS is described more often in women with low birth weight and high birth weight, while other studies have failed to establish any relation. In this retrospective case-control study, we evaluated whether women diagnosed with PCOS had lower birth weight compared to women with a regular menstrual cycle (controls). Binary logistic regression models were used to analyze the data and correct for known confounders. About 65 women with PCOS and 96 controls were recruited for this purpose. The average birth weight of PCOS women (3357 g) did not differ from the average birth weight of controls (3409 g). Mean age at menarche differed significantly between groups, 13.7  years and 12.8  years (p = 0.006), respectively, for PCOS women and controls. In conclusion, we could not confirm the effect of adverse intrauterine conditions, reflected in birth weight, on developing PCOS.

A recent study in our laboratory has demonstrated that tetrachloroethylene (TCE) is acutely toxic to Japanese medaka (Oryzias latipes) larvae with a 96 hr-LC50 of 18 (17-19) mg/mL (Spencer et al., 2002). In the present study we hypothesize that TCE exposure induces a developmental effect in Japanese medaka. Growth and age specific sensitivity of Japanese medaka larvae were studied with four age groups (7, 14, 21 and 28 days old) to determine tetrachloroethylene effects on these parameters. The medaka larvae were exposed for 96 hours in a single concentration (10 mg/mL) of TCE. The toxic endpoints evaluated were larvae weight, length, water content and protein concentration. The study revealed that exposure of medaka larvae to this sub-acute concentration of TCE significantly reduced length and weight in the treated group. The difference in growth between control and treated groups was more obvious in age versus length, than in age versus weight. The dry weight-fresh weight ratio (dw/fw) was shown to be higher in the control group. Water content in TCE-treated medaka was higher than in the control group, and younger fry had more water content than older ones. A higher protein concentration was also observed in TCE-treated medaka compared to the control group. These results indicate that TCE has a profound effect on the growth and development of Japanese medaka larvae.

Purpose To evaluate the effectiveness of the Compelled Body Weight Shift (CBWS) therapy approach in the rehabilitation of individuals with chronic stroke. CBWS involves a forced shift of body weight towards a person’s affected side by means of a shoe insert that establishes a lift of the non-affected lower extremity. Method Eighteen individuals with chronic, unilateral stroke (mean age 57.7 ± 11.9 years, with a range of 35–75 years, mean time since stroke 6.7±3.9 years with a range of 1.1–14.1 years) who showed asymmetrical stance were randomly divided into two groups: the experimental group received a six-week physical therapy combined with CBWS therapy and the control group received only physical therapy. Both groups underwent a battery of identical tests (Fugl-Meyer assessment, Berg Balance Scale, weight bearing, and gait velocity) before the start of the rehabilitation intervention, following its completion, and three months after the end of therapy. Results After the intervention, weight bearing on the affected side (measured with the Balance Master®) increased in the experimental group to a larger degree compared to the control group (9.7% vs. 6.4%). Similarly, gait velocity increased 10.5% in the experimental group compared to the control group. Improvements in weight bearing and gait velocity were maintained in the experimental group after the three month retention period. Conclusion The study outcome revealed that a six-week intervention involving CBWS therapy could result in a long-lasting improvement of the symmetry of weight bearing and velocity of gait in individuals with chronic stroke.

To test the effect of a nurse-led intervention on weight gain in people with serious mental illness prescribed and taking second generation antipsychotic medication. Weight gain and obesity has reached epidemic proportions in the general population with the prevalence of Metabolic Syndrome reaching 20-25% of the global population. People with serious mental illness are at even higher risk, particularly those taking second generation antipsychotic medication. An experimental randomized controlled trial was undertaken. The control group received a 12-week healthy lifestyle booklet. In addition to the booklet, the intervention group received weekly nutrition and exercise education, exercise sessions, and nurse support. Participants (n = 101) were assessed at baseline and 12 weeks. Data were collected between March 2008-December 2010. Seven outcome measures were used: body measurements included girth (cm), weight (kg), height (cm), and body mass index (kg/m(2) ); questionnaires included the medication compliance questionnaire, the Drug Attitude Inventory, the Liverpool University Neuroleptic Side Effect Rating Scale, and the Medical Outcomes Study Short Form 36. Differences in primary outcome measures between baseline and 12 weeks follow-up were compared between intervention and control groups using standard bi-variate statistical tests. The study was conducted between 2008-2010. The analysis of outcome measures for the control group (n = 50) and intervention group (n = 51) was not statistically significant. There was a mean weight change of -0·74 kg at 12 weeks for the intervention group (n = 51), while the control group (n = 50) had a mean weight change of -0·17 kg at 12 weeks. The results were not statistically significant. © 2012 Blackwell Publishing Ltd.

To assess the effects of a 50% discount on low-energy density (ED) fruits and vegetables (F&V), bottled water, and diet sodas on shoppers' purchasing, food intake, and body weight. A randomized, controlled trial was conducted at two Manhattan supermarkets, in which a 4-week baseline period (no discounts) preceded an 8-week intervention period (50% discount), and a 4-week follow-up period (no discounts). Twenty-four hour dietary recall, as well as body weight and body composition measures were obtained every 4 weeks. Participants (n = 47, 33f; 14m) were overweight and obese (BMI ≥ 25) shoppers. Purchasing of F&V during intervention was greater in the discount group than in the control group (P < 0.0001). Purchasing of these items by the discount group relative to the control group during follow-up was reduced from intervention (P = 0.002), but still remained higher than during baseline (P = 0.01), indicating a partially sustained effect. Intake of F&V increased from baseline to intervention in the discount group relative to the control group (P = 0.037) and was sustained during follow-up. Body weight change did not differ significantly between groups, although post hoc analysis indicated a change within the discount group (-1.1 kg, P = 0.006) but not within the control group. Discounts of low-ED F&V led to increased purchasing and intake of those foods. Copyright © 2013 The Obesity Society.

Overweight and obesity are globally increasing risk factors for diseases in the context of metabolic syndrome. A randomized controlled trial was conducted to investigate whether there are any existing differences between two lifestyle intervention strategies with respect to weight reduction after 1 year. A total of 166 subjects with a body mass index of 28-35 kg/m 2 were enrolled in this trial at seven study centers; 109 were randomly allocated to the intervention group (comprehensive lifestyle modification program: web-based Individual Health Management [IHM]) with 3-month reduction phase plus 9-month maintenance phase, and 57 were allocated to the control group (written information with advice for healthy food habits: usual care [UC]). Body weight, waist circumference, blood pressure, laboratory findings, and bioimpedance analysis used to determine body composition were measured at baseline and after 3, 6, 9, and 12 months. The primary outcome parameter was body weight at month 12 compared to baseline. With respect to baseline status there were no statistically significant differences between the groups. Based on the intent-to-treat population, body weight showed a mean decrease of 8.7 kg (SD 6.1) in the intervention group (IHM) and 4.2 kg (SD 5) in the control group (UC) at month 12. This statistically significant difference ( P <0.001) was confirmed by various sensitivity analyses. Body mass index, waist circumference, high-density lipid cholesterol, body fat, and the ratio of fat and body cell mass improved to a significantly higher degree in the IHM group. IHM proved to be superior to UC in weight reduction after 1 year. With a mean loss of about 10% of the baseline weight, a clinically high relevant risk reduction for cardio-metabolic diseases is achievable.

Failure to maintain weight losses in lifestyle change programs continues to be a major problem and warrants investigation of innovative approaches to weight control. The goal of this study was to compare two novel group interventions, both aimed at improving weight loss maintenance, with a control group. A total of 103 women lost weight on a meal replacement-supplemented diet and were then randomized to one of three conditions for the 14-week maintenance phase: cognitive-behavioral treatment (CBT); CBT with an enhanced food monitoring accuracy (EFMA) program; or these two interventions plus a reduced energy density eating (REDE) program. Assessments were conducted periodically through an 18-month postintervention. Outcome measures included weight and self-reported dietary intake. Data were analyzed using completers only as well as baseline-carried-forward imputation. Participants lost an average of 7.6 +/- 2.6 kg during the weight loss phase and 1.8 +/- 2.3 kg during the maintenance phase. Results do not suggest that the EFMA intervention was successful in improving food monitoring accuracy. The REDE group decreased the energy density (ED) of their diets more so than the other two groups. However, neither the REDE nor the EFMA condition showed any advantage in weight loss maintenance. All groups regained weight between 6- and 18-month follow-ups. Although no incremental weight maintenance benefit was observed in the EFMA or EFMA + REDE groups, the improvement in the ED of the REDE group's diet, if shown to be sustainable in future studies, could have weight maintenance benefits.

To determine the effects on weight gain and temperature control of transferring preterm infants from incubators to open cots at a weight of 1600 g versus a weight of 1800 g. Randomised controlled trial. One tertiary and two regional neonatal units in public hospitals in Queensland, Australia. 182 preterm infants born with a birth weight less than 1600 g, who were at least 48 h old; had not required ventilation or continuous positive airways pressure within the last 48 h; were medically stable with no oxygen requirement, or significant apnoea or bradycardia; did not require phototherapy; and were enterally fed with an intake (breast milk/formula) of at least 60 ml/kg/day. Transfer into an open cot at 1600 or 1800 g. The primary outcomes were temperature stability and average daily weight gain over the first 14 days following transfer to an open cot. 90 infants in the 1600 g group and 92 infants in the 1800 g group were included in the analysis. Over the first 72 h, more infants in the 1800 g group had temperatures <36.4°C than the 1600 g group (p=0.03). From post-transfer to discharge, the 1600 g group had more temperatures >37.1°C (p=0.02). Average daily weight gain in the 1600 g group was 17.07 (SD±4.5) g/kg/day and in the 1800 g group, 13.97 (SD±4.7) g/kg/day (p=<0.001). Medically stable, preterm infants can be transferred to open cots at a birth weight of 1600 g without any significant adverse effects on temperature stability or weight gain.

Online social networks (OSNs) are a new, promising approach for catalyzing health-related behavior change. To date, the empirical evidence on their impact has been limited. Using a randomized trial, we assessed the impact of a health-oriented OSN with accelerometer and scales on participant's physical activity, weight, and clinical indicators. A sample of 349 PeaceHealth Oregon employees and family members were randomized to the iWell OSN or a control group and followed for 6 months in 2010-2011. The iWell OSN enabled participants to connect with "friends," make public postings, view contacts' postings, set goals, download the number of their steps from an accelerometer and their weight from a scale, view trends in physical activity and weight, and compete against others in physical activity. Both control and intervention participants received traditional education material on diet and physical activity. Laboratory data on weight and clinical indicators (triglycerides, high-density lipoprotein, or low-density lipoprotein), and self-reported data on physical activity, were collected at baseline, 3 months, and 6 months. At 6 months, the intervention group increased leisure walking minutes by 164% compared with 47% in the control group. The intervention group also lost more weight than the controls (5.2 pounds compared with 1.5 pounds). There were no observed significant differences in vigorous exercise or clinical indicators between the 2 groups. Among intervention participants, greater OSN use, as measured by number of private messages sent, was associated with a greater increase in leisure walking and greater weight reduction over the study period. The study provides evidence that interventions using OSNs can successfully promote increases in physical activity and weight loss.

This study investigated the effects of metformin and weight loss on biomarkers associated with breast cancer prognosis. Overweight/obese postmenopausal breast cancer survivors (n = 333) were randomly assigned to metformin vs placebo and to a weight loss intervention vs control (ie, usual care). The 2 × 2 factorial design allows a single randomized trial to investigate the effect of two factors and interactions between them. Outcomes were changes in fasting insulin, glucose, C-reactive protein (CRP), estradiol, testosterone, and sex-hormone binding globulin (SHBG). The trial was powered for a main effects analysis of metformin vs placebo and weight loss vs control. All tests of statistical significance were two-sided. A total of 313 women (94.0%) completed the six-month trial. High prescription adherence (ie, ≥80% of pills taken) ranged from 65.9% of participants in the metformin group to 81.3% of those in the placebo group (P < .002). Mean percent weight loss was statistically significantly higher in the weight loss group (-5.5%, 95% confidence interval [CI] = -6.3% to -4.8%) compared with the control group (-2.7%, 95% CI = -3.5% to -1.9%). Statistically significant group differences (ie, percent change in metformin group minus placebo group) were -7.9% (95% CI = -15.0% to -0.8%) for insulin, -10.0% (95% CI = -18.5% to -1.5%) for estradiol, -9.5% (95% CI = -15.2% to -3.8%) for testosterone, and 7.5% (95% CI = 2.4% to 12.6%) for SHBG. Statistically significant group differences (ie, percent change in weight loss group minus placebo group) were -12.5% (95% CI = -19.6% to -5.3%) for insulin and 5.3% (95% CI = 0.2% to 10.4%) for SHBG. As adjuvant therapy, weight loss and metformin were found to be a safe combination strategy that modestly lowered estrogen levels and advantageously affected other biomarkers thought to be on the pathway for reducing breast cancer recurrence and mortality.

Healthy weight loss represents a real challenge when obesity is increasing in prevalence. Herein, we report a conjugated polymer nanocarrier for smart deactivation of lipase and thus balancing calorie intake. After oral administration, the nanocarrier is sensitive to lipase in the digestive tract and releases orlistat, which deactivates the enzyme and inhibits fat digestion. It also creates negative feedback to control the release of itself. The nanocarrier smartly regulates activity of the lipase cyclically varied between high and low levels. In spite of high fat diet intervention, obese mice receiving a single dose of the nanocarrier lose weight over eight days, whereas a control group continues the tendency to gain weight. Daily intragastric administration of the nanocarrier leads to lower weight of livers or fat pads, smaller adipocyte size, and lower total cholesterol level than that of the control group. Near-infrared fluorescence of the nanocarrier reveals its biodistribution.Healthy weight loss represents a real challenge when obesity is increasing in prevalence.

This study investigated the effect of a low-fat, plant-based diet on body weight, metabolism, and insulin sensitivity, while controlling for exercise in free-living individuals. In an outpatient setting, 64 overweight, postmenopausal women were randomly assigned to a low-fat, vegan diet or a control diet based on National Cholesterol Education Program guidelines, without energy intake limits, and were asked to maintain exercise unchanged. Dietary intake, body weight and composition, resting metabolic rate, thermic effect of food, and insulin sensitivity were measured at baseline and 14 weeks. Mean +/- standard deviation intervention-group body weight decreased 5.8 +/- 3.2 kg, compared with 3.8 +/- 2.8 kg in the control group (P = .012). In a regression model of predictors of weight change, including diet group and changes in energy intake, thermic effect of food, resting metabolic rate, and reported energy expenditure, significant effects were found for diet group (P < .05), thermic effect of food (P < .05), and resting metabolic rate (P < .001). An index of insulin sensitivity increased from 4.6 +/- 2.9 to 5.7 +/- 3.9 (P = .017) in the intervention group, but the difference between groups was not significant (P = .17). Adoption of a low-fat, vegan diet was associated with significant weight loss in overweight postmenopausal women, despite the absence of prescribed limits on portion size or energy intake.

Suboptimal weight loss (SWL) and weight regain (WR) after gastric bypass surgery (GB) remains poorly understood. This study aims to compare GB patients experiencing SWL or significant WR (SigWR) with successful controls, regarding postoperative food intake, eating behavior, physical activity (PA), and psychometrics. Forty-nine patients with >1 year post-surgery were classified as either experiencing SWL (excess body weight loss, EWL, <50%, n = 22) or SigWR (total weight regain ≥15%, n = 38), with respective control groups. Energy intake (EI) was measured with a Food Frequency Questionnaire, eating behavior using the Dutch Eating Behavior Questionnaire and the Three-Factor Eating Questionnaire, and PA using both SenseWear Armbands and the International Physical Activity Questionnaire. Eating disorders, depression, and quality of life (QoL) were measured using the Eating Disorder Examination Questionnaire, Beck Depression Inventory II, and Impact of Weight on Quality of Life, respectively. EI, macronutrient distribution, and meal frequency were similar among groups. However, disinhibited eating behavior score was higher, while most subcategories from IWQOL were significantly lower in both SWL and SigWR groups compared with their respective controls. PA was significantly lower in the SWL and SigWR groups compared with the respective controls. There were no differences between groups regarding depression. Lower PA levels, disordered eating behavior and lower QoL are associated with unsuccessful weigh loss outcome after GB surgery. Longitudinal studies are needed to clarify the potential causal relationship between the previously described variables and SWL/SigWR after GB.

Objective To examine the impact of a weight loss intervention that focused on daily self-weighing for self-monitoring as compared to a delayed control group among 91 overweight adults. Design and Methods The 6-month intervention included a cellular-connected “smart” scale for daily weighing, web-based weight loss graph, and weekly emails with tailored feedback and lessons. An objective measure of self-weighing frequency was obtained. Weight was measured in clinic at 3 and 6 months. Caloric intake and expenditure, and perceptions of daily self-weighing were also measured. Results Using intent-to-treat analyses, the intervention group lost significantly more weight compared to the control group [Mean (95%CI); 3 months: −4.41%(−5.5, −3.3) vs. −0.37%(−1.5, .76); 6 months: −6.55%(−7.7, −5.4) vs. −0.35%(−1.5, .79); group×time interaction: p<.001] and a greater percentage achieved 5% (42.6% vs. 6.8%; p<.0001) and 10% (27.7% vs. 0%; p<.0001) weight loss. On average, the intervention group self-weighed more days/week (6.1±1.1 vs. 1.1±1.5; p<.0001) and consumed fewer calories/day compared to the control group [Mean (95% CI); 6 months: 1509 (1291,1728) vs. 1856 (1637,2074); group×time interaction: p=.006]. Among intervention participants, daily self-weighing was perceived positively. Conclusions These results indicate that an intervention focusing on daily self-weighing can produce clinically significant weight loss. PMID:23512320

The objective of this study was to determine whether a lifestyle intervention with individual counselling was cost-effective for reducing body weight compared with usual care from a company perspective. Overweight employees were recruited and randomly assigned to the intervention groups, either phone or Internet, or the control group. The intervention was based on a cognitive behavioural approach and addressed physical activity and diet. Self-reported body weight was collected at baseline and 12 months follow-up. Intervention costs and costs of sick leave days based on gross and net lost productivity days (GLPDs/NLPDs) obtained from the participating companies were calculated. Missing data were imputed using multiple imputation techniques. Uncertainty surrounding the differences in costs and the incremental cost-effectiveness ratios (ICER) was estimated by bootstrapping techniques, and presented on cost-effectiveness planes and cost-effectiveness acceptability curves. No statistically significant differences in total costs were found between the intervention groups and control group, though mean total costs in both intervention groups tended to be higher than those in the control group. The ICER of the Internet group compared with the control group was €59 per kilogram of weight loss based on GLPD costs. The probability of cost effectiveness of the Internet intervention was 45% at a willingness-to-pay of €0 per extra kilogram weight loss and 75% at a willingness-to-pay of €1500 per extra kilogram body weight loss. Comparable results were found for the phone intervention. The intervention was not cost effective in comparison with usual care from the company perspective. Due to the large amount of missing data, it is not possible to draw firm conclusions.

OBJECTIVE To test whether a weight loss program promotes greater weight loss, glycemic control, and improved cardiovascular disease risk factors compared with control conditions and whether there is a differential response to higher versus lower carbohydrate intake. RESEARCH DESIGN AND METHODS This randomized controlled trial at two university medical centers enrolled 227 overweight or obese adults with type 2 diabetes and assigned them to parallel in-person diet and exercise counseling, with prepackaged foods in a planned menu during the initial phase, or to usual care (UC; two weight loss counseling sessions and monthly contacts). RESULTS Relative weight loss was 7.4% (95% CI 5.7–9.2%), 9.0% (7.1–10.9%), and 2.5% (1.3–3.8%) for the lower fat, lower carbohydrate, and UC groups (P < 0.001 intervention effect). Glycemic control markers and triglyceride levels were lower in the intervention groups compared with UC group at 1 year (fasting glucose 141 [95% CI 133–149] vs. 159 [144–174] mg/dL, P = 0.023; hemoglobin A1c 6.9% [6.6–7.1%] vs. 7.5% [7.1–7.9%] or 52 [49–54] vs. 58 [54–63] mmol/mol, P = 0.001; triglycerides 148 [134–163] vs. 204 [173–234] mg/dL, P < 0.001). The lower versus higher carbohydrate groups maintained lower hemoglobin A1c (6.6% [95% CI 6.3–6.8%] vs. 7.2% [6.8–7.5%] or 49 [45–51] vs. 55 [51–58] mmol/mol) at 1 year (P = 0.008). CONCLUSIONS The weight loss program resulted in greater weight loss and improved glycemic control in type 2 diabetes. PMID:24760261

Hormonal fluctuations during the menstrual cycle influence energy intake and expenditure as well as eating preferences and behavior. We examined the effect in healthy, overweight, premenopausal women of a diet and exercise weight-loss program that was designed to target and moderate the effects of the menstrual cycle compared with the effect of simple energy restriction. A total of 60 healthy, overweight, premenopausal women were included in a 6-mo weight-loss program in which each subject consumed a diet of 1600 kcal/d. Subjects were randomly assigned to either a combined diet and exercise program that was tailored to metabolic changes of the menstrual cycle (Menstralean) or to undergo simple energy restriction (control). Thirty-one women (19 Menstralean and 12 control women) completed the study [mean ± SD body mass index (in kg/m(2)): 32.0 ± 5.2]. Both groups lost weight during the study. In an intention-to-treat analysis, the Menstralean group did not achieve a clinically significant weight loss compared with that of the control group (P = 0.61). In per-protocol analyses, a more-pronounced weight loss of 4.3 ± 1.4 kg (P = 0.002) was shown in adherent Menstralean subjects than in the control group. A differentiated diet and exercise program that is tailored to counteract food cravings and metabolic changes throughout the menstrual cycle may increase weight loss above that achieved with a traditional diet and exercise program in women who can comply with the program.

Five different East Coast Fever (ECF) (Theileria parva infection) control strategies, based on tick control and/or ECF immunization, were tested in groups of traditionally managed Sanga cattle in the Central Province of Zambia over a period of 2.5 years. Two groups were kept under intensive tick control (sprayed weekly), one group immunized and one non-immunized. Two further groups were under no tick control, one group immunized and one non-immunized, while a fifth group was immunized against ECF and maintained under strategic tick control (18 sprays per year). Tick control increased milk production and weight gain but not fertility. Immunization had neither marked detrimental nor beneficial effects on the cattle productivity. The combination of strategic tick control and immunization resulted in the highest level of production and at the same time reduced the potential risk from other tick-borne diseases.

To investigate whether a controlled physical training plan for overweight dogs during a weight loss program would improve cardiorespiratory fitness and better preserve lean body mass, compared with results for dogs undergoing a weight loss program based on caloric restriction alone. Prospective, nonrandomized clinical study. 19 client-owned overweight or obese dogs. All dogs were fed the same calorie-restricted diet rationed to achieve a weight loss rate of 1% to 2%/wk for 12 weeks. The fitness-and-diet (FD) group participated in a training program that included underwater and land-based treadmill exercise 3 times/wk. The diet-only (DO) group had no change in exercise routines. Daily activity before and during the intervention was recorded by accelerometry. Before and after intervention, heart rate during exercise was recorded to assess cardiovascular fitness, and body composition was analyzed by dual-energy x-ray absorptiometry. Differences between groups were evaluated with t tests and multiple regression analysis. Mean weight loss was 13.9% and 12.9% for the FD and DO groups, respectively (n = 8 dogs/group that completed the study). Mean accelerometer counts during intervention were 13% higher than baseline counts for the FD group. Heart rate during exercise declined after intervention in both groups. Lean body mass was preserved in the FD group and lost in the DO group during intervention. The controlled exercise plan used with a dietary weight loss program prevented loss of lean body mass in dogs. This finding supports inclusion of controlled physical training for obesity management in dogs.

The purpose of this study was to compare the efficacy of two home-based weight loss interventions that differ only in the amount of outside support provided. This was a 12-week, randomized, controlled trial. One group received limited support (LWS, n = 35) via a single 10 min phone call each week while another group received no weekly support (NWS, n = 28). Both the LWS and NWS received pre-packaged meals (PM) and shakes. A third group served as control (CON, n = 30) and received no components of the intervention. Weight loss at 12 weeks was the primary outcome. Diet (PM, shake, and fruit/vegetable (F/V) intake) and physical activity (PA) were self-monitored, recorded daily and reported weekly. An exit survey was completed by participants in the intervention groups upon completion of the study. Weight loss and percent weight loss in the LWS, NWS, and CON groups were 7.7 ± 4.4 kg (8.5 ± 4.2%), 5.9 ± 4.1 kg (6.0 ± 4.2%), and 0.3 ± 1.9 kg (0.4 ± 1.2%), respectively. The decrease in body weight and percent weight loss was significantly greater in the LWS and NWS groups when compared to the CON group and the percent weight loss was significantly greater in the LWS when compared to both the NWS and CON groups. A home-based weight loss program utilizing PM and shakes results in clinically significant percent weight loss and the addition of a brief weekly call promotes additional percent weight loss. © 2009 Asian Oceanian Association for the Study of Obesity .

This study investigates the effects of melatonin on the sperm quality and testis weight after the combination of swimming exercise and nandrolone decanoate (DECA). Two groups of male Wistar rats were treated for eight weeks as follows; group A consist of CO (control), Sham, N (DECA), S (swimming) and NS (DECA plus swimming); and group B: Sham M (sham melatonin), M (melatonin), MN (melatonin plus DECA), MS (melatonin plus swimming), MNS (melatonin, DECA plus swimming). The motility of sperm was significantly improved in melatonin groups in comparison to N, S and NS groups (P≤0.05).  The left testes weight was decreased in N, NS and MNS groups, and the right testes weight was decreased in N,S,NS, MS and MNS groups in compare with the control group. This study concluded that melatonin probably could improve the sperm motility and sex organs weight after the combination of DECA and exercise.

To determine the tolerable upper intake level of pyridoxine-HCl in humans, we investigated the effects of excess pyridoxine-HCl administration on body weight gain, food intake, tissue weight, and urinary excretion of water-soluble vitamins in weaning rats. The weaning rats were freely fed ordinary diet containing 0.0007% pyridoxine-HCl (control diet) or the same diet with 0.1%, 0.5%, 0.8% or 1.0% pyridoxine-HCl for 30 days. The body weight gain in the 0.8% and 1.0% groups, and the total food intake in the 1.0% group were significantly lower than those in the control group. The urinary excretion of pantothenic acid in the pyridoxine-HCl added groups were higher than that in the control group, while excessive pyridoxine-HCl intake did not affect the urinary excretion of other water-soluble vitamins. These results showed that the no-observed-adverse-effect-level (NOAEL) for pyridoxine-HCl was 0.1% in diet, corresponding to 90 mg/kg body weight/day, and lowest-observed-adverse-effect-level (LOAEL) was 0.5% in diet, corresponding to 450 mg/kg body weight/day.

Haemodialysis is the most common form of medical management of patients affected by end-stage renal disease (ESRD). For haemodialysis to be successful, strict fluid and weight control is recommended. Education, in terms of self-care activities, is an important intervention for improving patients' outcomes. A self-efficacy promotion training programme can be an effective strategy to bring about behavioural change. The aim of this study was to investigate the effect of a self-efficacy promotion training programme on the body weight changes in patients undergoing haemodialysis. In this single-blind quasi-experimental study, we recruited a convenience sample of 63 patients undergoing haemodialy-sis from two teaching hospitals and allocated them randomly to the experimental or control group. Patients in the experimental group received a six-session self-efficacy promotion training programme while the control group received the routine care of the institute. Mean body weight gain and self-efficacy were measured before, immediately and two months after the study. The groups did not differ significantly regarding the study variable before the study. However, immediately and two months after the study, the mean body weight gain and self-efficacy in the experimental group were significantly lower and higher, respectively, than the control group (p < 0.05). Implementing a self-efficacy promotion training programme is effective in decreasing weight gain and increasing self-efficacy in patients undergoing haemodialysis. Nurses in haemodialysis units can use self-efficacy promotion training programmes as an effective intervention for improving patients' outcomes. © 2012 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Maternal prepregnancy obesity (BMI ≥30 kg/m(2)) and excessive gestational weight gain (GWG) have shown a strong positive association with a higher BMI and risk of obesity in the offspring. The aim of this study is to estimate the effect of a GWG restriction program for obese pregnant women on the children's BMI at 5 years of age and weight-for-length/height (WL/H) development from 2 months of age until 5 years of age. This was a follow-up study of 302 children (137 children in an intervention group and 165 children in a control group) whose mothers participated in a weight gain restriction program during pregnancy. BMI at five years of age did not differ between girls and boys in the intervention and control group. The degree of maternal GWG, <7 kg or ≥7 kg, did not affect the offspring's WL/H. Compared with Swedish reference data, just over half of the children in both the intervention and control group had a BMI within the average range, whereas slightly more than one-third of the children had a higher BMI. Despite a comprehensive gestational intervention program for obese women containing individual weekly visits and opportunity to participate in aqua aerobic classes, there were no differences between BMI or weight development among the offspring at 5 years of age in the intervention and control group.

Overweight and obese youth, who face increased risk of medical complications including heart disease and type II diabetes, can benefit from sustainable physical activity interventions that result in weight loss. This study examined whether a 20-week exergame (i.e. videogame that requires gross motor activity) intervention can produce weight loss and improve psychosocial outcomes for 54 overweight and obese African American adolescents. Participants were recruited from a public high school and randomly assigned to competitive exergame, cooperative exergame, or control conditions. All exergame participants were encouraged to play the Nintendo Wii Active game for 30-60 minutes per school day in a lunch-time or after-school program. Cooperative exergame participants worked with a peer to expend calories and earn points together, whereas competitive exergame participants competed against a peer. Control participants continued regular daily activities. Outcome measures included changes in weight, peer support, self-efficacy, and self-esteem, measured at baseline, and at approximately 10 weeks and 20 weeks. Growth curve analysis revealed that cooperative exergame players lost significantly more weight (M = 1.65 kg; SD = 4.52) than the control group, which did not lose weight. The competitive exergame players did not differ significantly from the other conditions. Cooperative exergame players also significantly increased in self-efficacy compared to the control group, and both exergame conditions significantly increased in peer support more than the control group. Exergames, especially played cooperatively, can be an effective technological tool for weight loss among youth. PMID:23592669

1999-04-01

D-tagatose is a ketohexose, tastes like sugar and is useful as a low-calorie sweetener. To assess D-tagatose's safety, an oral 90-day toxicity study was conducted on male and female Crl:CDBR rats at dietary doses of 5, 10, 15, and 20% D-tagatose. One control group (dietary control) received only lab chow; a second control group received 20% cellulose/fructose in the diet. There were no treatment-related effects at 5% D-tagatose in the diet. At higher doses, treatment-related effects included transient soft stools in male and female animals from the 15 and 20% dose groups. This was anticipated as a result of the osmotic effect of a large dose of relatively undigested sugar and was not considered a toxic effect. All treatment groups gained weight over the study period; however, mean body weights were statistically significantly decreased in the 15 and 20% dose-group males and the 20% dose-group females at selected intervals compared to dietary control animals. No significant reduction in mean food consumption was noted in the treatment groups compared to the dietary control. Statistically significantly increased relative liver weights were noted in male and female animals from the 10, 15, and 20% dose groups compared to the dietary control. No gross pathological findings correlated with these increased liver weights. Minimal hepatocellular hypertrophy was observed in male and female animals from the 15 and 20% dose groups. An independent review of the liver slides concluded that histomorphologic changes associated with D-tagatose were restricted hepatocyte hypertrophy and hepatocyte glycogen accumulation. Therefore, it was concluded that increased liver weights and minimal hypertrophy were the result of adaptation to the high dietary levels (greater than 5% in the diet) of D-tagatose. No adverse effects were seen at 5% D-tagatose in the diet. Copyright 1999 Academic Press.

Resistance training (RT) has been shown to decrease fat mass (FM), and increase fat-free mass (FFM), which can be a useful for weight loss maintenance. To examine the effects of a 1-year RT intervention on weight loss maintenance following a 6-month dietary weight loss intervention. Following a 6-month dietary weight loss intervention (-6% ± 5.8; 5.05 kg ± 4.45), 70 postmenopausal women living with overweight or obesity were randomized to a control group (n = 34) or a RT group (n = 36) (3×/week first 6 months, 2×/week last 6 months, 70-80% of 1-repetition maximum). Body composition (DXA), abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) (CT scan), resting energy expenditure (EE) (indirect calorimetry), physical activity EE and total daily EE were measured (doubly-labelled water). A total of 54 participants completed the study (control group n = 29; RT group n = 25) and compliance to the RT program was on average 64%. Significant regains were noted for body weight 0.98 (3.71) kg vs. 1.33 (3.94) kg and FM regain 1.32 (2.69) kg vs. 0.81 (3.26) kg in control and RT groups after the 1-year weight maintenance phase. No group differences were noted. Resting EE and total daily EE did not change after the weight maintenance phase, and no differences were observed between groups. Both groups had significantly greater than predicted decrease in resting EE after the 6-month dietary intervention and at the end of the 1-year weight-loss maintenance phase. Our results suggest that a 1-year RT intervention following a 6-month dietary weight loss intervention does not improve weight loss maintenance, body composition or EE in post-menopausal women living with overweight or obesity.

Background Combatting over-weight or obesity can lead to large fluctuations in an individual’s body weight, often referred to as weight cycling or “yo-yo” dieting. Current evidence regarding the potentially damaging effects of these changes is conflicting. Methods Here, we assess the metabolic effects of weight cycling in a murine model, comprising three dietary switches to normal or high fat diets at 6 week intervals; male C57BL/6 mice were fed either a control (C) or high fat (F) diet for 6 weeks (n=140/group). C and F groups were then either maintained on their initial diet (CC and FF respectively) or switched to a high fat (CF) or control (FC) diet (n=35/group). For the final 6 week interval, CC and CF groups were returned to the control diet (CCC and CFC groups) while FC and FF groups were placed on a high fat diet (FCF and FFF) (n=28/group). Results For the majority of metabolic outcomes changes aligned with dietary switches; however assessment of neuropeptides and receptors involved in appetite regulation and reward signalling pathways reveal variable patterns of expression. Furthermore, we demonstrate that multiple cycling events leads to a significant increase in internal fat deposition, even when compared to animals maintained on a high fat diet (Internal Fat: FCF: 7.4 ± 0.2g vs. FFF: 5.6 ± 0.2g; p<0.01). Conclusions Increased internal adipose tissue is strongly linked to the development of metabolic syndrome associated conditions such as type 2 diabetes, cardiovascular disease and hypertension. While further work will be required to elucidate the mechanisms underlying the neuronal control of energy homeostasis, these studies provide a causative link between weight cycling and adverse health.

To evaluate the effectiveness of FUEL Your Life, a translation of the Diabetes Prevention Program for worksites. A randomized control group design was conducted in five worksites of a large transportation company. Measures were collected pretest, posttest (6 months), and follow-up (12 months). Railroad maintenance facilities of Union Pacific Railroad. Participants consisted of 362 workers (227 treatment, 135 control). FUEL Your Life was translated from the Diabetes Prevention Program to better fit within the context of the worksite. The primary difference was the use of peer health coaches to provide social support and reinforcement and an occupational nurse to provide lesson content (six sessions of 10 minutes) to participants instead of the lifestyle coaches employed by the Diabetes Prevention Program, resulting in a less structured meeting schedule. The primary outcomes were weight and body mass index (BMI), with secondary outcomes including eating behaviors, physical activity, and social support. Latent growth modeling was used to measure changes in the outcomes over time. Participants in the intervention group maintained weight/BMI (-.1 pounds/-.1 BMI), whereas the control participants gained weight/BMI (+2.6 pounds/+.3 BMI), resulting in a statistically significant difference between groups. Fifty-five percent of intervention participants lost some weight, whereas only 35% of the control group lost weight. FUEL Your Life, a low intensity intervention, was not effective for promoting weight loss, but was effective for helping workers maintain weight over a 12-month period.

This study explored differences in psychosocial and physiological variables in response to being presented with information on weight loss through either reading text on a website or listening to the same information via podcast. Participants were randomized to receive a weight loss website (n = 20) or podcast (n = 20). Participants had skin conductance levels measured and completed questionnaire items assessing demographic characteristics, user control, novelty, and knowledge. Participants in the podcast group exhibited greater levels of physiological arousal and reported the intervention to be more novel than those in the Web group; however, the Web group reported greater user control. There was no difference in knowledge between the groups. This study presents the first step in examining the role that novelty and user control may play in two different weight-loss electronic media, as well as differences in knowledge acquisition. Future research should explore adding additional media features, such as video content, to the podcasts and websites in order to optimize fully the different mediums and to examine whether user control and novelty are potential mediators of weight loss outcomes.

To compare the behaviors of rats with depressions induced by chronic forced swimming stress under two different conditions. Eighteen male rats were randomly divided into 3 groups, with 6 rats in each group. The rats in the control group (C group) were not forced into swimming, while the rats in the stress groups (S1 and S2) were forced to swim for 14 consecutive days. The rats in S1 group and S2 group swam for five minutes every morning, in water with (23 +/- 1) degree C, and (10 +/- 0.5) degree C in temperature, respectively. The weight gain, food intake, open-field test and saccharin solution test were observed on the seventh day and fourteenth day. On the seventh day following chronic swim stress, the rats in the S2 group had significant lower ratio in weight gain and food intake than the controls (P < 0.05). On the fourteenth day, the rats in the S2 group had significant lower ratio in weight gain (12.26 +/- 4.04)%, food intake (9.49 +/- 0.96)%, sucrose intake (28.63 +/- 3.51) g, and preference for saccharin solution (76.25 +/- 2.51)%, and less number of crossing (12.17 +/- 9.00) and times of rearing (3.17 +/- 3.60) than the controls (P < 0.05). The rats in the S1 group had significant lower ratio in weight gain and food intake than the controls on the seventh day following forced swimming. On the fourteenth day, the rats in the S1 group still had lower ratio in weight gain, but had higher ratio in food intake and preference for saccharin solution, and greater number of crossing than the controls. Chronic forced swimming at a lower temperature could induce depression better than at a higher temperature.

Objective: To explore the correlation among the pre-pregnant body mass index (BMI), gestational weight gain (GWG) and umbilical cord blood C peptide, and to investigate the influence of maternal weight management on the incidence of baby long-term metabolic syndrome. Methods: During May to Aug.2015, 485 pregnant women in Zhejiang Taizhou first people's hospital and Taizhou Huangyan maternal &child care service centre were selected in random and divided into four groups according to pre-pregnant BMI: low body mass, normal body mass, over body mass and obese group, and also divided into two groups for getting gestational diabetes mellitus (GDM) or not. According to the gestational weight gain (GWG), all the cases were divided into two groups: above the Institute Of Medicine (IMO) 2009 recommendations or not. According to the outcome, the GDM group which had received weight control treatment, was divided into successful treat group or not. At last, we tested the umbilical cord blood C peptide and birth weight of each newborn and compared the difference in all subgroups. The correlation between the umbilical cord blood C peptide and birth weight were analysed. Results: (1) In the pre-pregnant BMI groups, there were significant differences of incidence of GDM ( P <0.05). But, there were no significant differences of incidence of GWG in four groups ( P >0.05). (2) Newborn birth weight and the umbilical cord blood C peptide were positively correlated ( r =0.673, P <0.05). (3) Umbilical cord blood C peptide showed the correlation in all subgroups for different pre-pregnant BMI, GDM or not, overweight or not ( P <0.05), but only the GDM or not group had relation to newborn birth weight in all subgroups. (4) All groups showed correlations with neonatal umbilical cord blood C peptide, the GDM mostly (β=0.58), pre-pregnant BMI secondly (β: 0.36, 0.38) , and GWG weakly (β=0.17). (5) By stratification analysis, in GDM group, low body mass was negatively correlated with umbilical cord blood C peptide ( P <0.05, β=-1.41); in non-GDM group, over body mass group and obsess group were positively correlated with umbilical cord blood C peptide ( P <0.05, β=0.37, 0.46). Conclusion: There was direct correlation between the pre-pregnant body mass index, the gestational weight gain and umbilical cord blood C peptide. Suitable maternal weight control especially pre-pregnant body mass index control will lower the baby long-term metabolic syndrome incidence.

[Purpose] To compare the effects of treadmill training with partial body weight support (TTPBWS) and conventional physical therapy (PT) on subjects with anterior cruciate ligament reconstructions. [Subjects and Methods] A total of 40 subjects were randomly allocated to either a treatment group or a control group. Subjects received either treadmill training with partial body weight support (treatment group) or conventional physical therapy (control group). The circumferences of the lower extremities, Holden classifications, 10-meter walking times and the International Knee Documentation Committee (IKDC) scores were compared at 12 and 24 weeks post-operation. The knee joint stability was tested at 24 weeks post-operation using a KT-1000. [Results] Significant differences were found between the two groups at the 12 weeks post-operation. For most of the measures, there was no significant difference between the groups at 24 weeks post-operation. Interestingly, for most of the measures, there was no significant difference between their values in the treatment group at 12 weeks and their values in the control group at 24 weeks post-operation. [Conclusion] The function of a subject's lower extremities can be improved and the improvement was clearly accelerated by the intervention of treadmill training with partial body weight support, without compromising the stability of the knee joints in a given follow-up period.

Adenosine triphosphate-binding cassette (ABC) sub-family G member-2 (ABCG-2) is a transporter protein, implicated for multi-drug efflux from tissues. This study evaluated the effect of fluoroquinolones; levofloxacin, pazufloxacin and enrofloxacin, and non-steroidal anti-inflammatory drug, meloxicam; on the immunolocalization of ABCG-2 transporter protein of rabbit retinas. Thirty-two male rabbits were randomly divided in to eight groups. Control group was gavaged, 2% benzyl alcohol in 5% dextrose since these chemicals are excipients of the drug preparations used in the treatment groups of this study. Four groups were exclusively gavaged, levofloxacin hemihydrate (10 mg/kg body weight b.i.d 12 h), pazufloxacin mesylate (10 mg/kg body weight b.i.d 12 h), enrofloxacin (20 mg/kg body weight o.d.), and meloxicam (0.2 mg/kg body weight o.d.), respectively. Three other groups were co-gavaged meloxicam with above fluoroquinolones, respectively. These drugs were administered for 21 days. ABCG-2 immunolocalization was mild in the retinas of control and levofloxacin-alone-treated groups. The immunolocalization intensity was significantly higher in meloxicam-alone-treated group when compared to control and levofloxacin-alone-treated groups. Immunolocalization of this transporter increased in the levofloxacin-meloxicam co-treated group when compared to the levofloxacin-alone-treated group. Highest immunolocalization was observed in the enrofloxacin-meloxicam co-treated group although the immunolocalization of all treatment groups, except the levofloxacin-alone-treated group, was significantly higher than the control and levofloxacin-alone-treated groups.

Pregnancy increases the risk of being overweight at a later time period, particularly when there is excessive gestational weight gain. There remains a paucity of data into the effect of low glycaemic index (GI) pregnancy interventions postpartum. To examine the impact of a low glycaemic index diet during pregnancy on maternal diet 3 months postpartum. This analysis examined the diet, weight and lifestyle of 460 participants of the ROLO study 3 months postpartum. Questionnaires on weight, physical activity, breastfeeding, supplement use, food label reading and dietary habits were completed. The intervention group had significantly greater weight loss from pre-pregnancy to 3 months postpartum than the control group (1.3 vs. 0.1 kg, p = 0.022). The intervention group reported greater numbers following a low glycaemic index diet (p < 0.001) and reading food labels (p = 0.032) and had a lower glycaemic load (GL) (128 vs. 145, p = 0.014) but not GI (55 vs. 55, p = 0.809) than controls. Low GI dietary interventions in pregnancy result in improved health-behaviours and continued reported compliance at 3 months postpartum possibly through lower dietary GL as a result of portion control. Greater levels of weight loss from pre-pregnancy to 3 months postpartum in the intervention group may have important positive implications for overweight and obesity.

Background We studied the impact of the multicomponent interventions on body weight and cardiometabolic risk factors in overweight individuals working in corporate worksites. Methods Overweight (BMI ≥ 23 kg/m2) subjects were recruited from four randomised worksites [two active intervention (n, recruited, 180, completed 156) and two control (n, recruited 130, completed 111)]. Intensive intervention was given at intervention worksite. Results High prevalence (%) of obesity (90.9, 80.2), abdominal obesity (93.5, 84.3), excess skinfold thickness (70.3, 75.9), and low high-density lipoprotein cholesterol (HDL-c) levels (56.8, 63.7) were seen in the intervention and the control group, respectively. At the end of intervention, the following significant changes were observed in the intervention group: decrease in weight, BMI, waist circumference, serum triglycerides, and increase in HDL-c. Weight loss of more than 5% was seen in 12% and 4% individuals in the intervention and control groups, respectively. Most importantly, the sum of all the skinfold measurements (mm) in the intervention group decreased significantly more than the control group (12.51 ± 10.38 versus 3.50 ± 8.18, resp.). Conclusion This multicomponent worksite trial showed a reduction in weight, excess subcutaneous fat, and cardiometabolic risk factors after 6 months of active intervention in overweight Asian Indians.

Emphasis on enhancing baseball pitch velocity has become popular, especially through weighted-ball throwing. However, little is known about the physical effects or safety of these programs. The purpose of this study was to examine the effects of training with weighted baseballs on pitch velocity, passive range of motion (PROM), muscle strength, elbow torque, and injury rates. A 6-week weighted ball training program would result in a change in pitching biomechanical and physical characteristics. Randomized controlled trial. Level 1. During the baseball offseason, 38 healthy baseball pitchers were randomized into a control group and an experimental group. Pitch velocity, shoulder and elbow PROM, shoulder strength, elbow varus torque, and shoulder internal rotation velocity were measured in both groups. The experimental group then performed a 6-week weighted ball throwing program 3 times per week using balls ranging from 2 to 32 ounces while the control group only used a 5-ounce regulation baseball. Both groups performed a strength training program. Measurements were then repeated after the 6-week period. Injuries were tracked over the 6-week training program and the subsequent baseball season. The effect of training with a weighted ball program was assessed using 2-way repeated-measures analysis of variance at an a priori significance level of P < 0.05. Mean age, height, mass, and pretesting throwing velocity were 15.3 ± 1.2 years (range, 13-18 years), 1.73 ± 0.28 m, 68.3 ± 11 kg, and 30.3 ± 0.7 m/s, respectively. Pitch velocity showed a statistically significant increase (3.3%) in the experimental group ( P < 0.001). There was a statistically significant increase of 4.3° of shoulder external rotation in the experimental group. The overall injury rate was 24% in the experimental group. Four participants in the experimental group suffered elbow injuries, 2 during the training program and 2 in the season after training. No pitchers in the control group were injured at any time during the study. Performing a 6-week weighted ball throwing program increased pitch velocity. However, the program resulted in increased shoulder external rotation PROM and increased injury rate. Although weighted-ball training may increase pitch velocity, caution is warranted because of the notable increase in injuries and physical changes observed in this cohort.

Under experimental clinical conditions diet modification has been shown to reduce serum cholesterol levels. This paper reports such a positive response to a nonpharmacologic, behavioral education program at the worksite. Employees at the New York Telephone Company corporate headquarters were assigned randomly to treatment and control groups. Treatment consisted of an 8-week group cholesterol reduction program conducted during employee lunch hours. It comprised a multiple-treatment approach--food behavior change techniques combined with nutrition education, physical activity planning, and self-management skills. The treatment group showed substantial change compared with the control group at the program's completion. Those treated displayed a significant 6.4% reduction in total serum cholesterol (266 mg% average at baseline) as compared with control subjects with a corresponding decrease in high-density lipoprotein levels. A significant increase in nutrition knowledge and moderate weight loss were also documented for this group. The magnitudes of a participant's baseline serum cholesterol level and his/her reduction in percentage of ideal body weight were positively and independently correlated with percentage changes in serum cholesterol levels. Over the same period, decreases in high-density lipoprotein levels and no changes in serum cholesterol, weight, and nutrition knowledge were observed for the control group. Overall, participants in the treatment program successfully reduced the coronary heart disease risk factors of elevated cholesterol and weight. Directions for future study are suggested.

Background/Objectives. Embolization of the left gastric artery (LGA), which preferentially supplies the gastric fundus, has been shown to produce weight loss in animal models. However, weight loss after LGA embolization in humans has not been previously established. The aim of this study was to evaluate postprocedural weight loss in patients following LGA embolization. Subjects/Methods. A retrospective analysis of the medical records of patients who underwent LGA embolization for upper gastrointestinal (GI) bleeding was performed. Postprocedural weight loss in this group was compared to a control group of patients who had undergone embolization of other arteries for upper GI bleeding. Results. The experimental group (N = 19) lost an average of 7.3% of their initial body weight within three months of LGA embolization, which was significantly greater than the 2% weight loss observed in the control group (N = 28) (P = 0.006). No significant differences were seen between the groups in preprocedural body mass index (BMI), age, postprocedural care in the intensive care unit, history of malignancy, serum creatinine, or left ventricular ejection fraction. Conclusions. The current data suggest that body weight in humans may be modulated via LGA embolization. Continued research is warranted with prospective studies to further investigate this phenomenon. PMID:25349724

Body weight loss is an important feature of heart failure (HF) and tumors. It is related to both reduced survival and adverse reactions to therapy in both of these conditions. The mechanisms of body weight loss in patients with HF and tumors are considered to be similar. Yet, studies comparing those two populations are generally lacking. The aim of this study was to compare anthropometric and laboratory data, related to weight loss, between patients with chronic HF and patients with different tumors as well as control population. Laboratory and anthropometric data on 143 consecutive patients with chronic HF and malignant diseases as well as data for 20 controls were collected. Patients with HF had lower levels of C-reactive protein (CRP) and albumin compared to controls. Anthropometric measurements revealed lower body mass index (BMI), muscle strength, mid-arm circumference, and waist circumference in patients with HF compared to controls. Measurements of biceps, triceps, subscapular, and suprailiac skinfolds were also lower in HF group. Compared to solid tumor group, HF patients had lower levels of CRP and higher levels of hemoglobin. Solid tumor patients had lower values of BMI and subscapular skinfold thickness, as well as higher muscle strength compared to HF group. Finally, compared to patients with solid hematological tumors, HF group had lower levels of albumin, lower muscle strength, as well as lower mid-arm circumference. We found differences in anthropometric and laboratory features, related to weight loss, in patients with HF compared to control population that were expected. On the other hand, observed differences in HF group compared to patients with various tumors could imply different pathophysiological mechanisms of weight loss between those groups. Such data could serve as a cornerstone for studies with larger numbers of patients and deeper pathophysiological insight.

[Effect of starvation on blood protein levels in the population of Dobrinja (1992-1995)].

In nutritional protein deficiency, numerous studies verified utilization of amino acids generated from tissue degradation in intensive protein synthesis. Unlike liver, muscle protein synthesis is extremely dependent on external supplies of essential amino acids. Prolonged nutritional protein deficiency results in decrease of body weight as well as total protein concentration, in particular in early days of starvation. In prolonged starvation during the war, significant decrease of body weight was registered in 70 subjects while their total protein concentration remained within the expected range and did not significantly differ the values recorded in the control group. Concentration of serum albumines in the control group was lower than the concentration recorded in the tested group, while the serum globulins concentration was higher in the control group. Although the difference in body weight between the tested and the control group was statistically significant, no significant difference in the concentration of total proteins, albumines and globulines was recorded.

Weight loss in obesity can reduce morbidity and mortality and benefits persist as long as weight loss is maintained. Weight maintenance is difficult in the long term and new strategies need to be developed to achieve this goal. We aimed to evaluate the efficacy of substituting a low-calorie diet formula for a meal in a weight loss program during the maintenance phase. Randomized paralleled clinical trial including 62 adult patients with at least a 5% weight loss with diet alone for 6 months, randomized to two groups: daily replacement of one meal with a low-calorie diet formula, or dieting alone for another 6 months (weight maintenance phase). Weight maintenance or further weight loss occurred in 83.9% of patients in the intervention group, whereas only in 58.1% in the control group (P=0.025). As a whole, patients in the intervention group lost a further 3.2+/-3.7% of initial weight compared with a 1.3+/-3.6% in the control group (P=0.030). Body fat mass diminished in both groups, with no differences between them (1.6+/-3.5 vs 1.0+/-9.3 kg, respectively, P=0.239), and the same happened with free fat mass (0.9+/-3.3 vs 0.4+/-6.7 kg, respectively, P=0.471). A multivariate logistic regression analysis (R (2)=0.114, P=0.023) retained only the intervention as a predictor of the achievement of weight maintenance with an odds ratio (95% confidence interval) of 3.756 (1.138-12.391). Substitution of a low-calorie diet formula for a meal is an effective measure for weight loss maintenance compared with dieting alone.

Purpose Obesity increases risk for all-cause and breast cancer mortality and comorbidities in women who have been diagnosed and treated for breast cancer. The Exercise and Nutrition to Enhance Recovery and Good Health for You (ENERGY) study is the largest weight loss intervention trial among survivors of breast cancer to date. Methods In this multicenter trial, 692 overweight/obese women who were, on average, 2 years since primary treatment for early-stage breast cancer were randomly assigned to either a group-based behavioral intervention, supplemented with telephone counseling and tailored newsletters, to support weight loss or a less intensive control intervention and observed for 2 years. Weight and blood pressure were measured at 6, 12, 18, and 24 months. Longitudinal mixed models were used to analyze change over time. Results At 12 months, mean weight loss was 6.0% of initial weight in the intervention group and 1.5% in the control group (P < .001). At 24 months, mean weight loss in the intervention and control groups was 3.7% and 1.3%, respectively (P < .001). Favorable effects of the intervention on physical activity and blood pressure were observed. The weight loss intervention was more effective among women older than 55 years than among younger women. Conclusion A behavioral weight loss intervention can lead to clinically meaningful weight loss in overweight/obese survivors of breast cancer. These findings support the need to conduct additional studies to test methods that support sustained weight loss and to examine the potential benefit of intentional weight loss on breast cancer recurrence and survival.

OBJECTIVE--To test the short term efficacy of a self directed treatment manual for bulimia nervosa. DESIGN--Randomised controlled trial of the manual against cognitive behavioural therapy and a waiting list. SETTING--Tertiary referral centre. SUBJECTS--81 consecutive referrals presenting with bulimia nervosa or atypical bulimia nervosa. MAIN OUTCOME MEASURES--Frequency of binge eating, vomiting, and other behaviours to control weight as well as abstinence from these behaviours. RESULTS--Cognitive behavioural treatment produced a significant reduction in the frequency of binge eating, vomiting, and other behaviours to control weight. The manual significantly reduced frequency of binge eating and weight control behaviours other than vomiting, and there was no change in the group on the waiting list. Full remission was achieved in five (24%) of the group assigned to cognitive behavioural treatment, nine (22%) of the group who used the manual, and two (11%) of the group on the waiting list. CONCLUSIONS--A self directed treatment manual may be a useful first intervention in the treatment of bulimia nervosa. PMID:8142791

The obesity epidemic has major public health consequences. Expert dietetic and behavioural counselling with intensive follow-up is effective, but resource requirements severely restrict widespread implementation in primary care, where most patients are managed. We aimed to estimate the effectiveness and cost-effectiveness of an internet-based behavioural intervention (POWeR+) combined with brief practice nurse support in primary care. We did this pragmatic, parallel-group, randomised controlled trial at 56 primary care practices in central and south England. Eligible adults aged 18 years or older with a BMI of 30 kg/m(2) or more (or ≥28 kg/m(2) with hypertension, hypercholesterolaemia, or diabetes) registered online with POWeR+-a 24 session, web-based, weight management intervention lasting 6 months. After registration, the website automatically randomly assigned patients (1:1:1), via computer-generated random numbers, to receive evidence-based dietetic advice to swap foods for similar, but healthier, choices and increase fruit and vegetable intake, in addition to 6 monthly nurse follow-up (control group); web-based intervention and face-to-face nurse support (POWeR+Face-to-face [POWeR+F]; up to seven nurse contacts over 6 months); or web-based intervention and remote nurse support (POWeR+Remote [POWeR+R]; up to five emails or brief phone calls over 6 months). Participants and investigators were masked to group allocation at the point of randomisation; masking of participants was not possible after randomisation. The primary outcome was weight loss averaged over 12 months. We did a secondary analysis of weight to measure maintenance of 5% weight loss at months 6 and 12. We modelled the cost-effectiveness of each intervention. We did analysis by intention to treat, with multiple imputation for missing data. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN21244703. Between Jan 30, 2013, and March 20, 2014, 818 participants were randomly assigned to the control group (n=279), the POWeR+F group (n=269), or the POWeR+R group (n=270). Weight loss averaged over 12 months was recorded in 666 (81%) participants. The control group lost almost 3 kg over 12 months (crude mean weight: baseline 104·38 kg [SD 21·11; n=279], 6 months 101·91 kg [19·35; n=136], 12 months 101·74 kg [19·57; n=227]). The primary imputed analysis showed that compared with the control group, patients in the POWeR+F group achieved an additional weight reduction of 1·5 kg (95% CI 0·6-2·4; p=0·001) averaged over 12 months, and patients in the POWeR+R group achieved an additional 1·3 kg (0·34-2·2; p=0·007). 21% of patients in the control group had maintained a clinically important 5% weight reduction at month 12, compared with 29% of patients in the POWeR+F group (risk ratio 1·56, 0·96-2·51; p=0·070) and 32% of patients in the POWeR+R group (1·82, 1·31-2·74; p=0·004). The incremental overall cost to the health service per kg weight lost with the POWeR+ interventions versus the control strategy was £18 (95% CI -129 to 195) for POWeR+F and -£25 (-268 to 157) for POWeR+R; the probability of being cost-effective at a threshold of £100 per kg lost was 88% and 98%, respectively. No adverse events were reported. Weight loss can be maintained in some individuals by use of novel written material with occasional brief nurse follow-up. However, more people can maintain clinically important weight reductions with a web-based behavioural program and brief remote follow-up, with no increase in health service costs. Future research should assess the extent to which clinically important weight loss can be maintained beyond 1 year.

To study the effects of Bushen Huatan Compound (BHC) on the glycolipid metabolism and the expressions of the insulin signal conducting molecules inside ovaries in polycystic ovary syndrome (PCOS) model rats. Female Wistar rats were subcutaneously injected with 2.5 mg/kg testosterone propionate (Their female offspring were randomly divided into the medication group and the model group, 10 in each.) or neutral tea oil of the same dose (Ten female offspring was taken as the control group.) on the 16th day of pregnancy, once daily, for 3 successive days. BHC was given to rats in the medication group by gastrogavage, while equal volume of distilled water was given to rats in the model group and the control group by gastrogavage, both once daily for 20 successive days. The body weight and ovary weight were weighed to calculate the ratio of wet fat weight/body weight. The blood glucose levels were detected at 0, 0.5, 1, and 2 h using oral glucose tolerance test (OGTT). The serum concentrations of high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), fasting blood glucose (FBG), and insulin were detected to calculate homeostasis model assessment of insulin resistance (HOMA-IR). The expressions of protein kinase B (AKT2), glycogen synthase kinase-3beta (GSK3beta), glucose transporter-4 (GLUT4), extracellular signal regulated kinase-1 (ERK1) protein, P-AKT2, P-GSK3beta, and P-ERK1 in ovaries were detected using Western blot. Compared with the control group, the ratio of wet fat weight/ body weight, the blood glucose levels at 0.5 and 2 h in OGTT, and HOMA-IR all obviously increased, and the HDL-C level obviously decreased in the model group (P < 0.05). Compared with the model group, the ratio of wet fat weight/body weight and the blood glucose levels at 2 h in OGTT obviously decreased, and the HDL-C level obviously increased in the medication group (P < 0.05). The expressions of AKT2, P-AKT2, GSK3beta, P-GSK3beta, GLUT4, and ERK1 in the ovary tissue were obviously lower in the model group than in the control group (P < 0.05). The expressions of GSK3beta, P-GSK3beta, and GLUT4 were more obviously enhanced in the medication group than in the model group (P < 0.05). Insulin resistance and glucolipid metabolism dysfunction existed in female PCOS rats. Besides, abnormal insulin signaling pathway existed in the ovary tissue. BHC could remarkably ameliorate the IR degree and glucolipid metabolism functions, and might be correlated with regulating the protein expressions of insulin signal conducting molecules.

Objective: To evaluate the effect of intrahepatic cholestasis of pregnancy (ICP) on neonatal birth weight. Methods: Potential articles were identified by searching PubMed and Web of Science databases on April 30th, 2017. Using the Mantel-Haenszel random-effects or fixed-effects model, outcomes were summarized through weighted mean difference (WMD) and 95% confidence intervals (CI). Potential publication bias was tested using a funnel plot and the methods of Egger’s regression and Begg’s test. Results: A total of eight studies were included in our meta-analysis. Six studies reported data on neonatal birth weight in ICP and control pregnancies. Pooled data from the six studies showed that the birth weight in the ICP group was significantly lighter than in the control group. The overall pooled WMD was -175 g (95% CI: -301, -48). Meanwhile, pooled data from the other two studies indicated that the birth weight in the late-onset ICP group was heavier than in the early-onset ICP group (WMD: 267 g, 95% CI: 168, 366). Conclusion: Neonatal birth weights in ICP pregnancies were lower than in normal pregnancies. Furthermore, early-onset ICP is associated with a lower birth weight than late-onset ICP. PMID:28825589

Stress and negative emotions have been shown to be critical factors in inducing overeating as a form of maladaptive coping in obese people. The present study aimed to evaluate the efficacy of an 8-week stress management programme that includes progressive muscle relaxation (PMR) and diaphragmatic breathing on weight loss and eating behaviour in a sample of overweight and obese women who started a weight-loss programme. A total of 34 women with a mean (SD) body mass index of 38.17 (7.19) kg m(-) ² and mean (SD) age 47.35 (11.64) years were recruited from the outpatients Obesity Clinic of a public hospital in Athens. Participants were randomly assigned into a Stress Management (SM) and a control group. Anthropometric measurements were taken before and after the intervention, and the participants completed the following questionnaires: Dutch Eating Behaviour Questionnaire (DEBQ), Eating Attitudes Test (Eat-26), Health Locus of Control (HLC) and Perceived Stress Scale (PSS) before and after the intervention. The findings indicated a significant improvement in weight loss in the SM group [4.44 (0.83) kg] after intervention compared to the control group [1.38 (0.78) kg] (P < 0.05). A higher restrained eating behaviour was observed in the SM group after intervention compared to the control group, although there was no significant difference in perceived stress levels. The intervention group showed greater weight reduction, possibly because of the stress management programme, and a greater dietary restraint was demonstrated by them compared to the control group. It is likely that stress management could facilitate weight loss in obese women; however, more studies are needed to confirm this hypothesis. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

Protein consumption has been associated with cardio-metabolic benefits, including weight loss and improved insulin sensitivity, and may have potential benefits for individuals with fatty liver disease (FLD). We investigated the effect of increasing dietary protein intake from whey relative to carbohydrate on hepatic steatosis. A two-year randomized, double-blind, placebo-controlled trial of 30 g/day whey protein-supplemented beverage (protein) or an energy-matched low-protein high-carbohydrate beverage (control) for cardio-metabolic and bone health in 219 healthy elderly women, recruited from the Western Australian general population. Hepatic steatosis was quantified using computed tomographic liver-to-spleen (L/S) ratio. FLD was defined as liver-to-spleen difference <10 Hounsfield units. At baseline, FLD prevalence was 11.4%. Control and protein groups were similar in body mass index (BMI), insulin resistance, L/S ratio and FLD prevalence at baseline. At two-years, dietary protein increased by 20 g in the protein, but not the control, group. Total energy intake and physical activity remained similar between groups. At two-years, BMI and FLD prevalence increased in both groups, with no between group differences. L/S ratio increased in control, but not protein, group at two-years, with no between group differences. In a within group comparison, change in BMI correlated with changes in L/S ratio in control (r = 0.37, P = 0.0007), but not with protein group (r = 0.04, P = 0.73). Increasing dietary protein intake from whey relative to carbohydrate does not reduce weight, hepatic steatosis or the prevalence of FLD in elderly women. However, it may prevent worsening of hepatic steatosis associated with weight gain. Australian New Zealand Clinical Trials Registry (Registration no. ACTRN012607000163404).

To determine the effectiveness of therapeutic touch on weight, the presence of postnatal complications, and length of hospital stay in preterm newborns, as well as on parental satisfaction with the care provided. We performed an experimental study in the Neonatal Intensive Care Unit of the Virgen Macarena University Hospital in Seville (Spain). Seventy eight premature neonates were randomly assigned to one of the comparison groups (39 in the control group and 39 in the experimental group). The outcome variables of weight, length of hospital stay, the presence of complications, and parental satisfaction were evaluated. Control variables related to maternal socio-demographic and clinic characteristics were also measured. The intervention was based on the application of therapeutic touch. The mean weight in grams was 1,867.80 (SD=149.72) in the experimental group and 1,860 (SD=181.92) in the control group (t=0.148; p=0.883). Length of hospital stay was 16.82 (SD=6.47) in the experimental group and 20.30 (SD=8.04) in the control group (t=2.100; p=0.039). Complications developed in 5.3% of the premature neonates in the experimental group and in 20% of those in the control group (chi(2)=3.78; p=0.049). The odds ratio for developing complications was 1.673 (CI 1.089-2.571). The application of therapeutic touch reduces the length of hospital stay and the presence of complications. Nevertheless, further research in larger samples is required.

A cognitive/behavioral group intervention for weight loss in patients treated with atypical antipsychotics.

Obesity and diabetes have caused problems for individuals with schizophrenia long before atypical antipsychotic agents. The prevalence of obesity, insulin resistance, impaired glucose tolerance, type 2 diabetes mellitus, dyslipidemia, and the Metabolic Syndrome has increased in people with schizophrenia as compared to the general population. Risk reduction studies for persons with obesity, diabetes, and cardiovascular disease indicate that cognitive/behavioral interventions that promote motivation and provide strategies to overcome the barriers in adherence to diet and activity modification are effective interventions for weight management and risk reduction. In the landmark multi-center randomized-controlled trial study, the Diabetes Prevention Project (DPP), a cognitive/behavioral intervention, was more successful in producing weight loss and preventing diabetes than the drugs metformin, troglitazone or placebo. This pilot study examined the effectiveness of a cognitive/behavioral group intervention, modified after the DPP program, in individuals with schizophrenia or schizoaffective disorder taking atypical antipsychotics in a large urban public mental health system. Outcome measures included body weight, body mass index, waist-hip ratios, and fasting glucose levels. Both groups demonstrated elevated fasting glucose levels and were obese with a mean BMI of 33. The group that received the cognitive/behavioral group intervention lost more weight than the treatment as usual group. The CB group participants lost an average of 5.4 lb or 2.9% of body weight, and those in the control group lost 1.3 lb or 0.6% body weight. The range of weight loss for the treatment group was from 1 to 20 lb. This pilot study has demonstrated that weight loss is possible with cognitive/behavioral interventions in a population with a psychotic disorder.

As overweight continues to rise among children, schools seek effective and sensitive ways to engage parents in promoting healthy weight. To evaluate a school-based health report card on the family awareness of and concern about the child weight status, plans for weight control, and preventive behaviors. Quasi-experimental field trial with a personalized weight and fitness health report card intervention (PI), a general-information intervention (GI), and a control group (CG). Outcomes were assessed using a postintervention telephone survey, including process and outcome measures. The intervention included 1396 ethnically diverse students at 4 elementary schools in an urban area. Telephone surveys were completed by 399 families from an evaluation sample of 793. Intervention Families were randomly assigned to the PI, GI, or CG and mailed intervention materials. The CG was mailed GI materials after the survey. Parent awareness of child weight status, concerns, weight-control plans, and preventive behaviors. Group effects were significantly different by the child's weight status, so results were stratified. Among overweight students, intervention parents were more likely to know their child's weight status (PI, 44%; GI, 41%; CG, 23%) (P =.02). The PI parents planned medical help (PI, 25%; GI, 7%; CG, 9%) (P =.004), dieting activities (PI, 19%; GI and CG, <5 cases) (P =.02) and physical activities (PI, 42%; GI, 27%; CG, 13%) (P<.001) for their overweight children. No group effect on concern or preventive behaviors was detected. Most parents of overweight children who read materials requested annual weight and health information on their child (PI, 91%; GI, 67%). Among overweight children, the PI was associated with increased parental awareness of their child's weight status. Although parents wanted PI for their children, more research is needed to test this approach on children's self-esteem and plans for weight control.

Post-gastrectomy weight loss is associated with deterioration in quality of life, and influences the long-term prognosis of gastric cancer patients. We conducted a prospective, randomized controlled, open-label study to examine whether an oral elemental diet (Elental(®), Ajinomoto Pharmaceuticals, Tokyo, Japan; hereafter referred to as ED) prevents postoperative weight loss in post-gastrectomy patients. Patients were randomly divided to receive the ED or control diet. The ED group received 300 kcal of ED plus their regular diet for 6-8 weeks after surgery, starting from the day the patient started a soft rice or equivalent diet after surgery, while the control group received the regular diet alone. The primary endpoint was the percentage of body weight loss (%BWL) from the presurgical body weight to that at 6-8 weeks after surgery. Secondary endpoints were dietary adherence, nutrition-related blood parameters, and adverse events. This study included 112 patients in eight hospitals. The mean treatment compliance rate in the ED group was 68.7 ± 30.4 % (median 81.2 %). The %BWL was significantly different between the ED and control groups (4.86 ± 3.72 vs. 6.60 ± 4.90 %, respectively; p = 0.047). In patients who underwent total gastrectomy, the %BWL was significantly different between the two groups (5.03 ± 3.65 vs. 9.13 ± 5.43 %, respectively; p = 0.012). In multivariate analysis, ED treatment, surgery type, and preoperative performance status were independently associated with %BWL. No significant differences were observed in the other clinical variables. ED supplementation reduced postoperative weight loss in gastric cancer patients undergoing gastrectomy.

Family meal frequency has been shown to be strongly associated with better dietary intake; however, associations with weight status have been mixed. Family meals-focused randomized controlled trials with weight outcomes have not been previously conducted. Therefore, this study purpose was to describe weight-related outcomes of the HOME Plus study, the first family meals-focused randomized controlled trial to prevent excess weight gain among youth. Families (n = 160 8-12-year-old children and their parents/guardians) were randomized to intervention (n = 81) or control (n = 79) groups. Data were collected at baseline (2011-2012), post-intervention (12-months post-baseline) and follow-up (21-months post-baseline). The intervention included ten monthly group sessions (nutrition education; hands-on meal and snack planning, preparation, and skill development; screen time reductions) and five motivational, goal-setting phone calls. The main outcome was child body mass index (BMI) z-score. General linear models, adjusted for baseline values and demographics, showed no significant treatment group differences in BMI z-scores at post-intervention or follow-up; however, a promising reduction in excess weight gain was observed. Post-hoc stratification by pubertal onset indicated prepubescent children in the intervention group had significantly lower BMI z-scores than their control group counterparts. The study used a strong theoretical framework, rigorous design, quality measurement and a program with high fidelity to test a family meals-focused obesity prevention intervention. It showed a modest decrease in excess weight gain. The significant intervention effect among prepubescent children suggests the intervention may be more efficacious among relatively young children, although more research with appropriately powered samples are needed to replicate this finding. This study is registered at www.clinicaltrials.gov NCT01538615. Registered 01/17/2012.

To test the efficacy of a low-intensive lifestyle education program (DiAlert) for overweight first degree relatives of type 2 diabetes patients aimed at reducing diabetes risk. Overweight first degree relatives of type 2 diabetes patients were randomly assigned to the DiAlert intervention (N=45) or control group who received leaflets (N=51). DiAlert consists of two group sessions and newsletters. Assessments were scheduled at baseline, three and nine months, with weight loss as primary outcome. Secondary outcomes included anthropometric, metabolic, behavioral and psychological measures. Comparisons were made over time and between groups. Both groups showed modest weight loss with no difference between randomization groups. However, after DiAlert significantly more participants lost 5% of their weight compared to controls (P=0.03). Significant improvement of waist circumference sustained after 9 months in the intervention group (intervention: -4.33cm, P<0.01/control: -1.25cm, P=0.08). Systolic blood pressure improved within the intervention group (intervention: -8.77mmHg, P<0.01/control: -1.03mmHg, P=0.60). No effect was observed for biomedical and psychosocial outcomes. Our low-intensive structured lifestyle education program helps overweight relatives to improve waist circumference and supports relevant weight loss. The family approach provides opportunities to reach and engage relatives at risk in diabetes prevention education. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Incorporating meal replacements has been shown to produce a significantly greater weight loss than a conventional reduced calorie diet. Ready-to-eat conventional foods may also be effective in this role and provide additional benefit because of their palatability, acceptance and enjoyment and thus increase dietary compliance. This trial investigated the efficacy of a ready-to-eat food product (Vita-Weat biscuit) that is both high in carbohydrate and high in protein as part of a diet prescription for weight loss in an overweight and obese population group. A total of 76 participants were randomized to a 6-week weight loss intervention including the ready-to-eat food product (intervention group) or advice on the 'Australian Guide to Healthy Eating' (control group). Both groups lost approximately 2 kg weight which equated to a reduction in body mass index of 0.70 kg m(-2) . There was no significant difference in percentage weight loss from screening to 6 weeks between the two groups; mean difference for the intervention vs. -0.20% (95% confidence interval: -0.96, 1.36); P = 0.73. Both diets were nutritionally matched and well-accepted over the 6-week period. This study shows that the inclusion of a ready-to-eat food product can be included as part of a dietary programme to achieve a clinically significant weight loss over a short period. This may have benefit when incorporated into an individual's meal plan intermittently to assist weight control. It also provides support for current public health nutritional guidelines as the participants in this study following such advice were also successful in achieving a clinically meaningful weight loss. © 2016 World Obesity.

We examined the association of body mass index (BMI), body weight perception, and weight control behaviors with problematic Internet use in a nationwide sample of Korean adolescents. Cross-sectional data from the 2010 Korean Youth Risk Behavior Web-based Survey collected from 37,041 boys and 33,655 girls in middle- and high- schools (grades 7-12) were analyzed. Participants were classified into groups based on BMI (underweight, normal weight, overweight, and obese), body weight perception (underweight, normal weight, and overweight), and weight control behavior (no weight control behavior, appropriate weight control behavior, inappropriate weight control behavior). The risk of problematic Internet use was assessed with the Korean Internet Addiction Proneness Scale for Youth-Short Form. Both boys and girls with inappropriate weight control behavior were more likely to have problematic Internet use. Underweight, overweight, and obese boys and girls were more likely to have problematic Internet use. For both boys and girls, subjective perception of underweight and overweight were positively associated with problematic Internet use. Given the negative effect of inappropriate weight control behavior, special attention needs to be given to adolescents' inappropriate weight control behavior, and an educational intervention for adolescents to control their weight in healthy ways is needed.

Stress contributes to physiological changes such as weight loss and hormonal imbalances. The aim of the present study was to investigate antistress effects of high hydrostatic pressure extract of ginger (HPG) in immobilization-stressed rats. Male Sprague-Dawley rats (n = 24) were divided into three groups as follows: control (C), immobilization stress (2 h daily, for 2 weeks) (S), and immobilization stress (2 h daily, for 2 weeks) plus oral administration of HPG (150 mg/kg body weight/day) (S+G). Immobilization stress reduced the body weight gain and thymus weight by 50.2% and 31.3%, respectively, compared to the control group. The levels of serum aspartate transaminase, alanine transaminase, and corticosterone were significantly higher in the stress group, compared to the control group. Moreover, immobilization stress elevated the mRNA levels of tyrosine hydroxylase (Th), dopamine beta-hydroxylase (Dbh), and cytochrome P450 side-chain cleavage (P450scc), which are related to catecholamine and corticosterone synthesis in the adrenal gland. HPG administration also increased the body weight gain and thymus weight by 12.7% and 16.6%, respectively, compared to the stress group. Furthermore, the mRNA levels of Th, Dbh, phenylethanolamine-N-methyltransferase, and P450scc were elevated by the HPG treatment when compared to the stress group. These results suggest that HPG would have antistress effects partially via the reversal of stress-induced physiological changes and suppression of mRNA expression of genes related to corticosterone and catecholamine synthetic enzymes.

Twenty-four 14-day-old weaner Avivastra (Russian MerinoxNali) male lambs were maintained for 180 days on ad libidum Cenchrus (Cenchrus ciliaris) hay and concentrate mixture (CM) contained groundnut meal (control) and mustard meal (MM group) as major protein source. The two CMs were isonitrogenous (21% CP) and isocaloric (2.78McalMEkg(-1) DM), while, CM fed to MM group contained 24.6mg glucosinolatesg(-1) DM. Digestibility of nutrients was similar (P>0.05) in the two groups except for CP and hemicellulose, which was higher (P<0.05) in control. Urinary N loss was higher (P<0.01) in control than in MM group, whereas N retention (% of N intake and absorbed) was higher (P<0.01) in MM group compared to control. Dry matter (gkg(-1)BW) and glucosinolate intakes were higher in MM fed group, whereas DCP and ME intakes were similar (P>0.05) in the two groups. Average daily gain (ADG) was, however, 22% higher (P<0.01) in control than in MM group. Hemoglobin and albumin contents were lower (P<0.01) in MM group than in control. Serum thiocyanate content was 26.7µgg(-1) in MM fed group, while it was not detected in control group. Thyroid weight was higher (P<0.01) while liver and kidney weights were lower (P<0.01) in MM group. Meat from dissected carcass of control group contained more protein and less fat, whereas the reverse was noticed in MM group. It is concluded that feeding mustard meal as protein supplement reduced growth rate and induced iodine deficiency. Carcass of lambs fed mustard meal had more fat and less protein.

The prevalence of male obesity is increasing but few men take part in weight loss programmes. We assessed the effect of a weight loss and healthy living programme on weight loss in football (soccer) fans. We did a two-group, pragmatic, randomised controlled trial of 747 male football fans aged 35-65 years with a body-mass index (BMI) of 28 kg/m(2) or higher from 13 Scottish professional football clubs. Participants were randomly assigned with SAS (version 9·2, block size 2-9) in a 1:1 ratio, stratified by club, to a weight loss programme delivered by community coaching staff in 12 sessions held every week. The intervention group started a weight loss programme within 3 weeks, and the comparison group were put on a 12 month waiting list. All participants received a weight management booklet. Primary outcome was mean difference in weight loss between groups at 12 months, expressed as absolute weight and a percentage of their baseline weight. Primary outcome assessment was masked. Analyses were based on intention to treat. The trial is registered with Current Controlled Trials, number ISRCTN32677491. 374 men were allocated to the intervention group and 374 to the comparison group. 333 (89%) of the intervention group and 355 (95%) of the comparison group completed 12 month assessments. At 12 months the mean difference in weight loss between groups, adjusted for baseline weight and club, was 4·94 kg (95% CI 3·95-5·94) and percentage weight loss, similarly adjusted, was 4·36% (3·64-5·08), both in favour of the intervention (p<0·0001). Eight serious adverse events were reported, five in the intervention group (lost consciousness due to drugs for pre-existing angina, gallbladder removal, hospital admission with suspected heart attack, ruptured gut, and ruptured Achilles tendon) and three in the comparison group (transient ischaemic attack, and two deaths). Of these, two adverse events were reported as related to participation in the programme (gallbladder removal and ruptured Achilles tendon). The FFIT programme can help a large proportion of men to lose a clinically important amount of weight; it offers one effective strategy to challenge male obesity. Scottish Government and The UK Football Pools funded delivery of the programme through a grant to the Scottish Premier League Trust. The National Institute for Health Research Public Health Research Programme funded the assessment (09/3010/06). Copyright © 2014 Hunt et al.

To study the skin prick test (SPT) reactivity to house dust mite allergens in overweight and normal weight children with allergic asthma before and after standard subcutaneous specific immunotherapy. Two hundred and fifteen children with allergic asthma who had positive SPT responses to Dermatophagoides pteronyssinus (DP) and Dermatophagoides farinae (DF) were enrolled. According to the weight index, they were classified into overweight (n=63) and normal weight groups (n=152). Skin indices (SI) to DP and DF were compared between the two groups at 6 months and 1 year after standard subcutaneous specific immunotherapy. The overweight group had a significantly larger histamine wheal diameter than the normal weight group after controlling the variation in testing time (P<0.05). After controlling the variation in weights, there were significant differences in the SIs to DP and DF before specific immunotherapy and at 6 months and 1 year after specific immunotherapy. At 6 months and 1 year after specific immunotherapy, the SIs to DP and DF were significantly reduced in both groups (P<0.05), and the overweight group had greater decreases in the SIs to DP and DF than the normal weight group. The overweight children with allergic asthma have stronger responses to histamine than the normal weight patients. Specific immunotherapy can reduce the reactivity to dust mite allergens in children with allergic asthma. Within one year after specific immunotherapy, the overweight children with allergic asthma have a significantly greater decrease in the reactivity to dust mite allergens than the normal weight patients.

Direct evidence for the effects of vegetable intake on weight loss is qualified. The study aimed to assess the effect of higher vegetable consumption on weight loss. A single blind parallel controlled trial was conducted with 120 overweight adults (mean body mass index=29.98 kg/m(2)) randomised to two energy deficit healthy diet advice groups differing only by doubling the serving (portion) sizes of vegetables in the comparator group. Data were analysed as intention-to-treat using a linear mixed model. Spearmans rho bivariate was used to explore relationships between percentage energy from vegetables and weight loss. After 12 months, the study sample lost 6.5±5.2 kg (P<0.001 time) with no difference between groups (P>0.05 interaction). Both groups increased vegetable intake and lost weight in the first 3 months, and the change in weight was significantly correlated with higher proportions of energy consumed as vegetables (rho=-0.217, P=0.024). Fasting glucose, insulin and triglyceride levels decreased (P<0.001 time) and high-density lipoprotein cholesterol levels increased (P<0.001 time), with no difference between groups. Weight loss was sustained for 12 months by both groups, but the comparator group reported greater hunger satisfaction (P=0.005). Advice to consume a healthy low-energy diet leads to sustained weight loss, with reductions in cardiovascular disease risk factors regardless of an emphasis on more vegetables. In the short term, consuming a higher proportion of the dietary energy as vegetables may support a greater weight loss and the dietary pattern appears sustainable.

To determine whether Kangaroo mother care (KMC) facilitates mother baby attachment in low birth weight infants. Over 16 month period 110 neonates were randomized into kangaroo mother care group and control group using a random number table. The kangaroo group was subjected to Kangaroo mother care for at least 6 hours per day. The babies also received kangaroo care after shifting out from NICU and at home. The control group received standard care (incubator or open care system). After 3 months followup, structured maternal interview was conducted to assess attachment between mothers and their babies. Mean birth weight was 1.69 +/- 0.11 Kg in KMC group compared to 1.690 +/- 0.12 Kg in control group (p>0.05). Mean gestational age was 35.48 +/- 1.20 week in KMC group and 35.04+/-1.09 week in the control group (p>0.05). KMC was initiated at a mean age of 1.72+/-0.45 days. The duration of KMC in first month was 10.21+/-1.50 hour, in the 2nd month was 10.03+/-1.57 hour and in the 3rd month was 8.97+/-1.37 hours. The duration of hospital stay was significantly shorter in the KMC group (3.56+/-0.57 days) compared to control group (6.80+/-1.30 days). The total attachment score (24.46+/-1.64) in the KMC group was significantly higher than that obtained in control group (18.22+/-1.79, p< 0.001). In KMC group, mother was more often the main caretaker of the baby. Mothers were significantly more involved in care taking activities like bathing, diapering, sleeping with their babies and spent more time beyond usual care taking. They went out without their babies less often and only for unavoidable reasons. They derived greater pleasure from their babies. KMC facilitates mother baby attachment in low birth weight infants.

To evaluate the effectiveness and sustainable impact of a multifaceted community-based weight intervention program for children, including exergaming curriculum. Eighty overweight or obese children, aged 8-12 years, were randomly assigned in a 2:1 ratio to an Exergaming for Health intervention group, comprising both exergaming and classroom curriculum, or to a control group with classroom curriculum alone. Outcome measures included body mass index (BMI), z-score change, and shuttle runs to assess cardiorespiratory endurance. Fifty-nine participants took part in the intervention and 21 in the control group, with 35 and 13 completing 6-month follow-up, respectively. Twenty-eight intervention children were followed-up at 1 year. At the end of the 6-month intervention, the intervention group reduced its BMI z-score by -0.06 (±0.12) compared to 0 (±0.09) change for the control group; additionally, intervention subjects were two shuttle runs higher than control. However, these differences were not statistically significant (P = 0.07 and P = 0.09, respectively). Over the 6-month period after the program, the intervention group did not have an increase in weight status (BMI z-score change -0.01 [95% confidence interval -0.08 to +0.06], P = 0.76). Use of exergaming in community pediatric weight management did not improve weight status at the end of programming, and study implementation was limited by small sample and missing data. However, there were clinically promising trends in fitness, screen time, and caloric intake. Weight status of intervention participants did not rebound 6 months after programming. Larger, longer term studies are needed to establish the impact of videogaming interventions.

Brackground:The safety and tolerability of very low-calorie-ketogenic (VLCK) diets are a current concern in the treatment of obese type 2 diabetes mellitus (T2DM) patients. Evaluating the short-term safety and tolerability of a VLCK diet (<50 g of carbohydrate daily) in an interventional weight loss program including lifestyle and behavioral modification support (Diaprokal Method) in subjects with T2DM. Eighty-nine men and women, aged between 30 and 65 years, with T2DM and body mass index between 30 and 35 kg m(-)(2) participated in this prospective, open-label, multi-centric randomized clinical trial with a duration of 4 months. Forty-five subjects were randomly assigned to the interventional weight loss (VLCK diet), and 44 to the standard low-calorie diet. No significant differences in the laboratory safety parameters were found between the two study groups. Changes in the urine albumin-to-creatinine ratio in VLCK diet were not significant and were comparable to control group. Creatinine and blood urea nitrogen did not change significantly relative to baseline nor between groups. Weight loss and reduction in waist circumference in the VLCK diet group were significantly larger than in control subjects (both P<0.001). The decline in HbA1c and glycemic control was larger in the VLCK diet group (P<0.05). No serious adverse events were reported and mild AE in the VLCK diet group declined at last follow-up. The interventional weight loss program based on a VLCK diet is most effective in reducing body weight and improvement of glycemic control than a standard hypocaloric diet with safety and good tolerance for T2DM patients.

The development and use of Web-based programs for weight loss is increasing rapidly, yet they have rarely been evaluated using randomized controlled trials (RCTs). Interestingly, most people who attempt weight loss use commercially available programs, yet it is very uncommon for commercial programs to be evaluated independently or rigorously. To compare the efficacy of a standard commercial Web-based weight-loss program (basic) versus an enhanced version of this Web program that provided additional personalized e-feedback and contact from the provider (enhanced) versus a wait-list control group (control) on weight outcomes in overweight and obese adults. This purely Web-based trial using a closed online user group was an assessor-blinded RCT with participants randomly allocated to the basic or enhanced 12-week Web-based program, based on social cognitive theory, or the control, with body mass index (BMI) as the primary outcome. We enrolled 309 adults (129/309, 41.8% male, BMI mean 32.3, SD 4 kg/m(2)) with 84.1% (260/309) retention at 12 weeks. Intention-to-treat analysis showed that both intervention groups reduced their BMI compared with the controls (basic: -0.72, SD 1.1 kg/m(2), enhanced: -1.0, SD 1.4, control: 0.15, SD 0.82; P < .001) and lost significant weight (basic: -2.1, SD 3.3 kg, enhanced: -3.0, SD 4.1, control: 0.4, SD 2.3; P < .001) with changes in waist circumference (basic: -2.0, SD 3.5 cm, enhanced: -3.2, SD 4.7, control: 0.5, SD 3.0; P < .001) and waist-to-height ratio (basic: -0.01, SD 0.02, enhanced: -0.02, SD 0.03, control: 0.0, SD 0.02; P < .001), but no differences were observed between the basic and enhanced groups. The addition of personalized e-feedback and contact provided limited additional benefits compared with the basic program. A commercial Web-based weight-loss program can be efficacious across a range of weight-related outcomes and lifestyle behaviors and achieve clinically important weight loss. Although the provision of additional personalized feedback did not facilitate greater weight loss after 12 weeks, the impact of superior participant retention on longer-term outcomes requires further study. Further research is required to determine the optimal mix of program features that lead to the biggest treatment impact over time.

To identify and describe homogenous profiles of female college students based on weight-related behaviors and examine differences across 5 sexual orientation groups. Data from the 2009-2013 College Student Health Survey (Minnesota-based survey of 2- and 4-year college students) were used to fit latent class models. Four profiles were identified across all sexual orientation groups: "healthier eating habits," "moderate eating habits," "unhealthy weight control," and "healthier eating habits, more physically active." Differences in patterns and prevalence of profiles across sexual orientation suggest need for interventions addressing insufficient physical activity and unhealthy weight control behaviors. Future interventions should consider the diversity of behavioral patterns across sexual orientation to more effectively address weight-related behavioral disparities.

Overweight and obese youth, who face increased risk of medical complications including heart disease and type II diabetes, can benefit from sustainable physical activity interventions that result in weight loss. This study examined whether a 20-week exergame (i.e., videogame that requires gross motor activity) intervention can produce weight loss and improve psychosocial outcomes for 54 overweight and obese African-American adolescents. Participants were recruited from a public high school and randomly assigned to competitive exergame, cooperative exergame, or control conditions. All exergame participants were encouraged to play the Nintendo Wii Active game for 30-60 min per school day in a lunch-time or after-school program. Cooperative exergame participants worked with a peer to expend calories and earn points together, whereas competitive exergame participants competed against a peer. Control participants continued regular daily activities. Outcome measures included changes in weight, peer support, self-efficacy, and self-esteem, measured at baseline, and at ∼10 and 20 weeks. Growth curve analysis revealed that cooperative exergame players lost significantly more weight (mean = 1.65 kg; s.d. = 4.52) than the control group, which did not lose weight. The competitive exergame players did not differ significantly from the other conditions. Cooperative exergame players also significantly increased in self-efficacy compared to the control group, and both exergame conditions significantly increased in peer support more than the control group. Exergames, especially played cooperatively, can be an effective technological tool for weight loss among youth. Copyright © 2012 The Obesity Society.

This association has been attributed to socialization effects (i.e., membership leads to disordered eating); however, selection effects (i.e., selecting into peer groups based on genetic and/or environmental predispositions toward disordered eating) could contribute to or even account for these associations. The current study was the first to use a co-twin control design to disentangle these types of selection factors from socialization effects. Participants included 610 female twins (ages 8–14) drawn from the Michigan State University Twin Registry. To comprehensively examine a range of eating pathology, several disordered eating attitudes and behaviors (e.g., body dissatisfaction, binge eating) were examined via self-report questionnaires. Questionnaires also were used to assess peer group emphasis on body weight and shape. Replicating previous results, significant individual-level associations were found between membership in weight conscious peer groups and disordered eating. However, co-twin control analyses indicated that these associations were largely due to genetic and/or shared environmental selection factors rather than pure socialization effects. Importantly, results remained unchanged when controlling for pubertal status, suggesting that effects do not vary across developmental stage. Overall, these findings question whether associations between weight conscious peer groups and disordered eating are due entirely to socialization processes. Future studies are needed to identify the specific genetic and/or shared environmental factors that may drive selection into weight conscious peer groups. PMID:27043917

Background: Obesity impairs cognition and health-related quality of life (HRQOL) in older adults; however, the appropriate treatment of obese older adults remains controversial. Objective: The objective was to determine the independent and combined effects of weight loss and exercise on cognition, mood, and HRQOL in obese older adults. Design: One hundred seven frail, obese older adults were randomly assigned to a control, weight-management (diet), exercise, or weight-management-plus-exercise (diet-exercise) group for 1 y. In this secondary analysis, main outcomes were Modified Mini-Mental State Examination (3MS) and total Impact of Weight on Quality of Life-Lite (IWQOL) scores. Other outcomes included Word Fluency Test, Trail Making Test Parts A and B, and Geriatric Depression Scale (GDS) scores. Results: Scores on the 3MS improved more in the diet (mean ± SE: 1.7 ± 0.4), exercise (2.8 ± 0.4), and diet-exercise (2.9 ± 0.4) groups than in the control group (0.1 ± 0.4) (between-group P = 0.0001–0.04); scores in the diet-exercise group improved more than in the diet group but not more than in the exercise group. Scores on the Word Fluency Test improved more in the exercise (4.1 ± 0.8) and diet-exercise (4.2 ± 0.7) groups than in the control group (−0.8 ± 0.8; both P = 0.001). For the Trail Making Test Part A, scores in the diet-exercise group (−11.8 ± 1.9) improved more than in the control group (−0.8 ± 1.9) (P = 0.001); a similar finding was observed for the Trail Making Test Part B. Scores on the IWQOL improved more in the diet (7.6 ± 1.6), exercise (10.1 ± 1.6), and diet-exercise (14.0 ± 1.4) groups than in the control group (0.3 ± 1.6) (P = 0.0001–0.03); scores in the diet-exercise group improved more than in the diet group but not more than in the exercise group. In the diet-exercise group, peak oxygen consumption and strength changes were independent predictors of 3MS changes; weight and strength changes were independent predictors of IWQOL changes. GDS scores did not change. Conclusions: Weight loss and exercise each improve cognition and HRQOL, but their combination may provide benefits similar to exercise alone. These findings could inform practice guidelines with regard to optimal treatment strategies for obese older adults. This trial was registered atclinicaltrials.govas NCT00146107. PMID:24787497

A functional dietary supplement (FDS) containing Coenzyme Q10, branched-chain amino acids and L-carnitine was administered to tumor-bearing mice, investigating its effects on tumor and muscle tissues. Experiment (A): B16 melanoma cells were implanted subcutaneously into the right side of the abdomen of 8- to 9-week-old C57BL/6J mice. The mice were divided into two groups: a FDS group that received oral administration of FDS (n=10), and a control group that received oral administration of glucose (n=10). The moribund condition was used as the endpoint, and median survival time was determined. Experiment (B): On day 21 after tumor implantation, tumors, soleus muscle, gastrocnemius muscle, and suprahyoid muscles were collected. Tumor and muscle weight and other aspects were evaluated in each group: FDS group (n=15) and control group (n=15). The median survival time was comparable (21 d in the FDS group vs. 18 d in the control group, p=0.30). However, cumulative food intake was significantly higher in the FDS group than the control group (p=0.011). Metastasis of melanoma to the lung was observed in the control group but not in the FDS group (p=0.043). The weight of the suprahyoid muscles was significantly higher in the FDS group than in the control group (p=0.0045). The weight of the tumor was significantly lower in the FDS group than in the control group (p=0.013). The results possibly suggest oral administration of FDS in tumor-bearing mice enhances the maintenance of suprahyoid muscles, resulting in an extended feeding period and suppression of tumor growth and metastasis.

Women tend to gain weight at midlife (40-60 years) increasing risk of obesity-related chronic diseases. Within specific eating occasions, needs related to the physical and social environment may result in less healthy eating behavior, which can lead to weight gain over time. The purpose of this study was to determine if a dietitian-delivered nutrition counseling intervention tailored to eating occasion needs could improve diet and prevent weight gain among midlife women over two years. A randomized controlled trial was conducted with healthy midlife women (n = 354) in one U.S. metropolitan area. The intervention group (n = 185) received ten hours of individual nutrition counseling from dietitians over six months, while women in a control group (n = 169) received no counseling. Measured height, weight and waist circumference, and dietary intakes were collected at baseline and every six months over two years. Mixed linear models were used to test for intervention effect on change in outcome variables over time. Dietary intakes of fruit, reduced/low-fat dairy foods and refined grains were significantly improved over time in the intervention compared to control group. However, the intervention had no effect on weight over time (p = 0.48). Nutrition counseling tailored to address eating occasion needs improved self-reported diet but did not significantly affect weight change.

Our objectives were to examine cognitive outcomes for extremely preterm/extremely low birth weight (EPT/ELBW, gestational age <28 weeks and/or birth weight <1000 g) children in kindergarten and the associations of these outcomes with neonatal factors, early childhood neurodevelopmental impairment, and socioeconomic status (SES). The sample comprised a hospital-based 2001-2003 birth cohort of 148 EPT/ELBW children (mean birth weight 818 g; mean gestational age 26 weeks) and a comparison group of 111 term-born normal birth weight (NBW) classmate controls. Controlling for background factors, the EPT/ELBW group had pervasive deficits relative to the NBW group on a comprehensive test battery, with rates of cognitive deficits that were 3 to 6 times higher in the EPT/ELBW group. Deficits on a measure of response inhibition were found in 48% versus 10%, OR (95% CI) = 7.32 (3.32, 16.16), p <.001. Deficits on measures of executive function and motor and perceptual-motor abilities were found even when controlling for acquired verbal knowledge. Neonatal risk factors, early neurodevelopmental impairment, and lower SES were associated with higher rates of deficits within the EPT/ELBW group. The findings document both global and selective cognitive deficits in EPT/ELBW children at school entry and justify efforts at early identification and intervention. PMID:21923973

Broiler eggs were either incubated at 37.8°C during the whole incubation period (control), or at higher (38.8°C, group H) and lower temperatures (36.8°C, group L) from embryonic day (ED) 7 up to ED 10 (ED 7 to 10) or from ED 10 up to ED 13 (ED 10 to 13). Before and after this temperature treatment the eggs were incubated at 37.8°C. The day-old chicks were weighted, sexed and fed up to day 35. On days 1 and 35 samples were taken from the breast and leg muscles for analyzing of the mitochondrial respiratory activity (MRA) and from the breast muscles for analysis of the cross-sectional areas (CSA) and the glycogen phosphorylase (GP), phosphofructokinase (PFK), lactate dehydrogenase (LDH), citrate synthase (CS) and cytochrome oxidase (COX) activities. Statistical analysis showed that treatment (control, group H, group L), sex and their interaction, but not the treatment period (ED 7 to 10; ED 10 to 13), significantly influenced the results. Group H chicks had lower (P⩽0.05) body and heart weights but higher (P⩽0.05) liver weights, CSA values, leg MRA as well as PFK, LDH, CS, GP and COX activities compared with the group L chicks. The results of the control chicks differ (P⩽0.05) from those of the group H (body, heart weight, COX), the group L chicks (liver weight, PFK, LDH, CS, GP) or the birds of both other groups (CSA). The group H broiler had higher (P⩽0.05) body and leg weights as well as LDH, CS, COX and GP activities than the group L broilers. The BWs and the LDH and GP results of the control broiler differ (P⩽0.05) from those of both other groups or from the results of the group H (CS) and group L broiler (COX). Female broilers had lower (P⩽0.05) body, breast and leg weights, but higher (P⩽0.05) CSA, LDH, CS and GP activities than the male animals. Analysis of treatment×sex interaction showed that group H hens had higher (P⩽0.05) body and breast weights, LDH and GP activities compared with the group L hens, whereas in the male broiler no effect of the interaction could be found, except for the lower (P⩽0.05) CSA values in the group H than group L cocks. The treatment effects are probably due to altered embryonic activity and related molecular mechanisms. The sex-related differences in the broiler indicate that these alterations already occur in the embryos and chicks, but become significant with the sexual dimorphism after hatch.

Background. Litramine (IQP-G-002AS) was shown to be effective and safe for weight loss in overweight and obese subjects. However, long-term effectiveness on maintenance of body weight loss has yet to be ascertained. Objective. To assess effect of Litramine on maintenance of body weight loss. Methods. A double-blind, randomised, placebo-controlled trial on overweight and obese patients was conducted over two sites in Germany for 24 weeks. Subjects with documented previous weight loss of 3% over the last 3–6 months were randomised to groups given either Litramine (3 g/day) or a matching placebo. Primary endpoints were difference of mean body weight (kg) between baseline and end of study and maintenance of initially lost body weight in verum group, where maintenance is defined as ≤1% weight gain. Results. Subjects who were taking Litramine lost significantly more body weight compared to the subjects taking placebo who gained weight instead (−0.62 ± 1.55 kg versus 1.62 ± 1.48 kg, p < 0.001). More importantly, 92% of subjects in Litramine group were able to maintain their body weight after initial weight loss, versus 25% in placebo group. No serious adverse events were reported throughout. Conclusion. Litramine is effective and safe for long-term body weight maintenance. Trial Registration. This trial is registered with Clinicaltrials.gov identifier: NCT01505387. PMID:26435849

Background Royal jelly (RJ) is a complementary diet widely prescribed by traditional medicine specialists for treatment of in- fertility. The aim of present study was to evaluate the effects of RJ on a set of reproductive parameters in immature female rats. Materials and Methods In this experimental study, thirty two immature female rats (30-35 g) were divided into four groups (n=8/group): three experimental groups and one control. The experimental groups received 100, 200 and 400 mg/kg/body weight doses of RJ daily for 14 days, and the control group received 0.5 ml distilled water interaperito- nealy (i.p). The treated rats were sacrificed and their ovaries were dissected for histological examination. The serum levels of ovarian hormones, nitric oxide (NO) and ferric reducing antioxidant power (FRAP) were evaluated, and the ratios of the ovarian and uterine weight to body weight were calculated. One-way ANOVA was used for data analysis. Results The body weights were significantly different (P=0.002) among the rat groups, with an increase in all RJ treated animals. Uterine and ovarian weights and the serum levels of progesterone (P=0.013) and estradiol (P=0.004) were significantly increased in experimental groups compared to the control group. In addition, a significant increase in the number of mature follicles and corpora lutea (P=0.007) was seen in RJ recipients compared to the controls. A significant increase in the serum levels of FRAP (P=0.009) and a significant decrease in NO level (P=0.013) were also observed. Conclusion RJ promotes folliculogensis and increases ovarian hormones. This product can be considered as a natural growth stimulator for immature female animals. PMID:29043701

Zn-deficiency has been associated with numerous alterations during pregnancy including low birth weight; however, the research relating neonatal zinc status and birth weight has not produced reliable results. To compare the serum Zn-levels of cord blood in healthy newborns and low birth weight newborns, and to assess a possible relationship between zinc concentration and neonatal birth weight and gestational age. 123 newborns divided in "study group" (n=50) with <2500g birth weight neonates and "control group" (n=73) with ≥2500g birth weight neonates were enrolled. Study group was subdivided according to gestational age in preterm (<37 weeks) and full-term (≥37 weeks). Serum cord blood samples were collected and the Zn-levels were analyzed using flame Atomic Absorption Spectrophotometry method and the result was expressed in μmol/L. The Zn-levels were compared between the groups (Mann-Whitney-U test) and the Zn-levels were correlated with the birth weight and gestational age (Spearman's rank correlations). Statistically significant low positive correlation between Zn-levels and birth weight (ρ=0.283; p=0.005) was found. No statistically significant difference between Zn-levels of study and control groups [17.00±0.43 vs. 18.16±0.32 (p=0.053)] was found. Statistically significant low positive correlation between Zn-levels and gestational age (ρ=0.351; p=0.001) was found. No statistically significant difference between Zn-levels of preterm as compare to full-term newborns [16.33±0.42 vs. 18.43±0.93 (p=0.079)] was found. Zn-level of preterm subgroup was significantly lower compared to control group (p=0.001). Despite low birth weight preterm neonates had significantly lower serum zinc levels of cord blood than healthy term neonates, the correlation between cord blood zinc levels and birth weight and gestational age was lower. The results are not enough to relate the change in cord blood zinc concentration to the birth weight values or gestational period. In relation to complicated pregnancies, further studies regarding zinc levels in blood in our population are required. Copyright © 2015 Elsevier GmbH. All rights reserved.

Asthma and obesity are public health problems with increasing prevalence worldwide. Clinical and epidemiologic studies have demonstrated that obese asthmatics have worse clinical control and health related quality of life (HRQL) despite an optimized medical treatment. Bariatric surgery is successful to weight-loss and improves asthma control; however, the benefits of nonsurgical interventions remain unknown. This is a randomized controlled trial with 2-arms parallel. Fifty-five moderate or severe asthmatics with grade II obesity (BMI ≥ 35 kg/m(2)) under optimized medication will be randomly assigned into either weight-loss program + sham (WL + S group) or weight-loss program + exercise (WL + E group). The weight loss program will be the same for both groups including nutrition and psychological therapies (every 15 days, total of 6 sessions, 60 min each). Exercise program will include aerobic and resistance muscle training while sham treatment will include a breathing and stretching program (both programs twice a week, 3 months, 60 min each session). The primary outcome variable will be asthma clinical control. Secondary outcomes include HRQL, levels of depression and anxiety, lung function, daily life physical activity, body composition, maximal aerobic capacity, strength muscle and sleep disorders. Potential mechanism (changes in lung mechanical and airway/systemic inflammation) will also be examined to explain the benefits in both groups. This study will bring a significant contribution to the literature evaluating the effects of exercise conditioning in a weight loss intervention in obese asthmatics as well as will evaluate possible involved mechanisms.

Strength is a physical quality with a clear influence on quality of life. It is determined by the structure of the musculoskeletal system, and depends on the muscular structure. It has been described that prematurity conditions both qualities. The aims of this study are to determine whether prematurity is associated with strength or body composition and evaluate the relationship between prematurity, strength and muscle mass. Case-control study. Participants were premature 7-to-11 year-old children and full-term birth controls. Strength was measured by a strength gauge and body composition from DEXA (duel-energy X-ray absorptiometry) scans. A total of 89 subjects were included and divided into three groups: 30 prematures with birth-weight ≤ 1500g, 29 prematures with birth-weight 1500-2000g, and 30 controls. Weight and BMI z-score was lower in the premature group. No differences were found in muscular mass or strength between groups. A ratio was established between strength and weight or muscular mass. It was observed that it was possible for them to move four times their weight, without finding any differences between groups or a relationship with birth-weight. Between 7 and 11 years of age, children who were premature have lower weight and BMI than the rest of the children. However, there were no differences in body composition or strength between preterm children and controls. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U.

Physical activity has been shown to have a positive effect on bone metabolism among adolescents. The objective of this study was to determine the effect of swimming on bone metabolism during adolescence. Swimming, as a non-weight-bearing sport, has been considered to be insignificant in the maintenance of bone mass. We studied whether swimming is associated with a higher peak bone mass. Forty swimmers (males aged 10-17 years and females aged 9-16 years) were studied. The control group consisted of the same number of adolescents aged between 10-16 years who did not swim; distribution of male and female gender was similar in the non-swimming control group compared to the swimming group. Adolescents were matched for age, gender and pubertal stages based on Tanner staging. All subjects underwent combined measurement of bone mineral metabolism by dual-energy X-ray absorptiometry of total body calcium content, and specific biochemical markers of turnover including osteocalcin, calcium, phosphorus and alkaline phosphatase. Bone age (determined by Greulich and Pyle's Radiographic Atlas of Skeletal Development of the Hand and Wrist), weight, height, ideal body weight, ideal body weight ratio, body mass index, Tanner classification (rated by examiner), diet, history of tobacco and alcohol exposure, exercise, socioeconomic status and history of chronic illness and medications were recorded to evaluate potential mediators that would affect bone metabolism. Tanner staging was used to assess puberty, and diet was evaluated based on reported consumption of milk, yogurt and cheese and cola/caffeine beverage consumption daily. There was significant difference in bone mineral content between adolescent male swimmers and the control group males. Consumption of cola beverages were significantly higher among the control group compared with the swimmer group. Ideal body weight ratio was significantly high among the female control group compared with female swimmers. Milk consumption was significantly higher for both male and female swimmer groups, whereas yogurt consumption was only significantly higher in the male swimmer group compared with control group. These results indicate that a highly active nonimpact sport such as swimming may lead to increased bone mineral content only for male swimmers. However, dietary behaviors may be more important than swimming on bone metabolism among adolescents.

The ideal nutritional approach for weight regain after bariatric surgery remains unclear. The objective of this study is to assess the effect of whey protein supplementation on weight loss and body composition of women who regained weight 24 or more months after bariatric surgery. This is a 16-week open-label, parallel-group, randomized controlled trial of women who regained at least 5 % of their lowest postoperative weight after a Roux-en-Y gastric bypass (RYGB). A total of 34 participants were treated with hypocaloric diet and randomized (1:1) to receive or not supplementation with whey protein, 0.5 g/kg of the ideal body weight. The primary outcomes were changes in body weight, fat free mass (FFM), and fat mass (FM), evaluated by tetrapolar bioelectrical impedance analysis (BIA). Secondary outcomes included resting energy expenditure, blood glucose, lipids, adiponectin, interleukin 6 (IL-6), and cholecystokinin levels. Statistical analyses included generalized estimating equations adjusted for age and physical activity. Fifteen patients in each group were evaluated: mean age was 45 ± 11 years, body mass index (BMI) was 35.7 ± 5.2 kg/m 2 , and time since surgery was 69 ± 23 months. Protein intake during follow-up increased by approximately 75 % in the intervention group (p = 0.01). The intervention group presented more body weight loss (1.86 kg, p = 0.017), accounted for FM loss (2.78, p = 0.021) and no change in FFM, as compared to controls (gain of 0.42 kg of body weight and 0.6 kg of FM). No differences in secondary outcomes were observed between groups. Whey protein supplementation promoted body weight and FM loss in women with long-term weight regain following RYGB.

Over the last three decades, overweight and obesity and the associated health consequences have become global public health priorities. Methods that have been tried to address this problem have not had the desired impact, suggesting that other approaches need to be considered. One of the lessons learned throughout these attempts is that permanent weight loss requires sustained dietary and lifestyle changes, yet adherence to weight management programs has often been noted as one of the biggest challenges. This trial aims to address this issue by examining whether social media, as a potential health promotion tool, will improve adherence to a weight management program. To test the effectiveness of this measure, the designated program will be delivered via the popular social networking site Facebook, and compared to a standard delivery method that provides exactly the same content but which is communicated through a pamphlet. The trial will be conducted over a period of twelve weeks, with a twelve week follow-up. Although weight loss is expected, this study will specifically investigate the effectiveness of social media as a program delivery method. The program utilised will be one that has already been proven to achieve weight loss, namely The CSIRO Total Wellbeing Diet. This project will be conducted as a 3-arm randomised controlled trial. One hundred and twenty participants will be recruited from the Perth community, and will be randomly assigned to one of the following three groups: the Facebook group, the pamphlet group, or a control group. The Facebook Group will receive the weight management program delivered via a closed group in Facebook, the Pamphlet Group will be given the same weight management program presented in a booklet, and the Control Group will follow the Australian Dietary Guidelines and the National Physical Activity Guidelines for Adults as usual care. Change in weight, body composition and waist circumference will be initial indicators of adherence to the program. Secondary outcome measures will be blood glucose, insulin, blood pressure, arterial stiffness, physical activity, eating behaviour, mental well-being (stress, anxiety, and depression), social support, self-control, self-efficacy, Facebook activity, and program evaluation. It is expected that this trial will support the use of social media - a source of social support and information sharing - as a delivery method for weight management programs, enhancing the reduction in weight expected from dietary and physical activity changes. Facebook is a popular, easy to access and cost-effective online platform that can be used to assist the formation of social groups, and could be translated into health promotion practice relatively easily. It is anticipated in the context of the predicted findings that social media will provide an invaluable resource for health professionals and patients alike.

Responses to life stressors are associated with negative behaviors that may increase risk for illness and injury. The effect of high intensity exercise in reducing reactivity to psychological stress has been well documented among older people. The purpose of this study was to ascertain the effect of weight-training versus aerobic dance on psychological stress in college students. 45 students participated in a weight-training course, 35 students participated in aerobic dance classes, and 34 students served as a control group. The Survey of Recent Life Experiences was used to appraise stressfulness of current experiences before and after exercise intervention. On immediate retest after 8 wk. of weight-training perceived stress was significantly reduced when compared with an 8-wk. aerobic dance program, but there were no significant differences between the control group and the weight-training group or the aerobic dance group. These results suggest that a regular routine of low intensity exercise such as weight-training may reduce perceived stress on an immediate test.

To compare the performance of children born premature with low birth weight (LBW) and very low birth-weight (VLBW) with that of children born at term, within the age range of one to three years, regarding child development in the gross motor, fine motor-adaptive, personal-social and language domains. This is a cross-sectional study in a cohort of 150 infants born premature (experimental group) and at term (control group) divided into eight groups with respect to weight (low birth weight: <2500 grams and very low birth weight: <1500 grams) and age range (aged 12 to 24 and 25 to 36 months). The control groups were paired with the experimental groups as for gender, chronological age, and socioeconomic level. Assessment comprised the application of anamnesis protocol, socioeconomic classification, and Denver Developmental Screening Test (DDST-II). Corrected age was calculated for premature children up to 24 months of age. Descriptive statistical analysis and the Student's t-test were used. No statistically significant difference was found in the comparison between the groups of infants born premature and at term for all domains evaluated. The performance of infants born premature was lower than that of infants born at term regarding the gross motor, fine motor-adaptive, personal-social and language domains. In this study, the preterm groups presented different performances, i.e., normative, average, and below average performances were observed within the same group.

Fear and stigmatization are often used to motivate individuals with higher body weight to engage in healthy behaviors, but these strategies are sometimes counterproductive, leading to undesirable outcomes. In the present study, the impact of weight-based stigma on cognition (i.e., inhibitory control) and food selection (i.e., calories selected) was examined among individuals who consider themselves to be overweight. It was predicted that participants higher in perceived weight stigma would perform more poorly on an inhibitory control task and order more calories on a food selection task when they read about discrimination against individuals with higher weight versus discrimination against an out-group. Participants completed online prescreen measures assessing whether they considered themselves to be overweight and their perceptions of weight stigma. Individuals who considered themselves to be overweight were invited into the laboratory to complete tasks that manipulated weight-based discrimination, then inhibitory control and food selection were measured. The higher participants were in perceived weight stigma, the more poorly they performed on the inhibitory control task and the more calories they ordered when they read about discrimination against individuals with higher body weight. These relationships were not observed when participants read about discrimination against an out-group. The present findings provide evidence that perceptions of weight stigma are critical in understanding the impact of weight-based discrimination. Additionally, these results have theoretical and practical implications for both understanding and addressing the psychological and physical consequences of weight-based stigma.

We examined the association of food cravings with weight loss and eating behaviors in a lifestyle intervention for weight loss in worksites. This research was part of a randomized controlled trial of a 6-month weight loss intervention versus a wait-listed control in 4 Massachusetts worksites. The intervention emphasized reducing energy intake by adherence to portion-controlled menu suggestions, and assessments were obtained in 95 participants at baseline and 6 months including non-fasting body weight, food cravings (Craving Inventory and Food Craving Questionnaire for state and trait) and the eating behavior constructs restraint, disinhibition and hunger (Eating Inventory). There were statistically significant reductions in all craving variables in the intervention group compared to the controls. Within the intervention group, changes in craving-trait were significantly associated with weight loss after controlling for baseline weight, age, gender and worksite. However, in a multivariate model with craving-trait and eating behaviors (restraint, disinhibition and hunger), hunger was the only significant predictor of weight change. In contrast to some previous reports of increased food cravings with weight loss in lifestyle interventions, this study observed a broad reduction in cravings associated with weight loss. In addition, greater reductions in craving-trait were associated with greater weight change, but craving-trait was not a significant independent correlate of weight change when hunger was included in statistical models. Studies are needed to examine the effectiveness of hunger suppressing versus craving-suppressing strategies in lifestyle interventions for obesity. Copyright © 2013 Elsevier Ltd.

To investigate whether high-fat diet induced obesity was associated with variation of glucose absorption in small intestinal mucosa of rats. 46 male SD rats were randomly divided into high-fat diet group (n = 31) and control group (n = 15), fed with high-fat diet and normal diet for 24 weeks, respectively. After 24 weeks, the rats were divided into obese (n = 16) and obesity-resistant group (n = 10) according to their body weight. Rats' body weight, abdominal fat weight, plasma glucose level, maltase, sucrase activity in small intestinal mucosa were measured. SGLT-1 expression in intestinal mucosa was detected by immunohistochemistry, RT-PCR and Western blot. Mean body weight, abdominal fat weight, fast plasma glucose levels, maltase activities and SGLT-1 protein expression in intestinal mucosa of obese rats were significantly higher than those in the control and obesity-resistant rats (P < 0.05). Sucrase activities in intestinal mucosa showed no statistical difference among the three groups (P > 0.05). The SGLT-1 mRNA expression in obese group was increased by 12.5% and 23% when compare with the control and obesity-resistant group, respectively. But the difference was not statistical significant (P > 0.05). High-fat diet induced obesity was associated with the increased intestinal maltase activity and expression of SGLT-1 in rats, the key molecule in glucose absorption.

We examined whether the incorporation of green tea extract enriched rye bread (GTRB) into the diet can improve weight loss (WL) maintenance and control of abnormalities linked to metabolic syndrome (MS). A total of 55 obese men and women (mean age: 53.0±7.0 years, body mass index: 35.0±5.5 kg m(-2)) were recruited. The study had a single-blind randomized study design and consisted of an 8-week WL phase with low-energy calorie diet, followed by a 12-week weight maintenance (WM) phase. During the WM phase, the subjects were randomized into two groups, receiving either the control rye bread (control group) or the GTRB (intervention group). The ingestion of 280 and 360 g GTRB provided daily totals of 123.2 and 158.4 mg caffeine, and 188.3 and 242.1 mg of epigallocatechin gallate, for women and men, respectively. After the WL phase, subjects lost 7.3±3.1 kg of their baseline body weight. GTRB intake did not significantly influence the maintenance of WL, high-density lipoprotein-cholesterol, triglycerides, and glucose concentrations. Although, it resulted in significant differences (mean difference [95% confidence interval]) between the treatment groups in the maintenance of waist circumference (-1.22 cm [-2.4, -0.02; P=.04]), the results were not clinically meaningful. Nevertheless, the ingestion of GTRB led to the maintenance of lower blood pressure (BP), also the proportion of subjects fulfilling the criteria of MS after the WM phase was lower in the intervention group than in the control group. Although GTRB consumption did not improve significantly the WL maintenance, it resulted in a better control of BP.

The aim of this study was to determine whether the implementation of Kangaroo Mother Care (KMC) to low birth weight infants would improve physical growth, breastfeeding and its acceptability. A randomized controlled trial was performed over 16 months in which 110 neonates were randomized into a KMC group and a control group using a random number table. The KMC group was subjected to KMC for at least 6 h per day. The babies also received KMC after moving from the neonatal intensive care unit and at home. The control group received standard care (incubator or open care system). Weight, length and occipitofrontal circumference (OFC) were measured weekly for three months. The acceptability of KMC by mothers and nursing staff was assessed on day 7 after the start of KMC using a questionnaire incorporating the Likert scale. Breastfeeding rates were calculated based on history at end of three months. The mean gestational age was 35.48 ± 1.20 weeks in the KMC group and 35.04 ± 1.09 weeks in the control group (P > 0.05). KMC was initiated at a mean age of 1.72 ± 0.45 days and the duration of KMC was 9.74 ± 1.48 h/day. The mean birth weight was 1.69 ± 0.11 kg in the KMC group compared to 1.69 ± 0.12 kg in the control group (P > 0.05). The mean weight gain in gm/day in the KMC group was 21.92 ± 1.44 compared to 18.61 ± 1.28 in the control group (P < 0.05). The mean length gain in cm/week was 1.03 ± 0.5 in the KMC group compared to 0.74 ± 0.05 in the control group (P < 0.05). The mean OFC gain in cm/week was 0.59 ± 0.04 in the KMC group compared to 0.47 ± 0.03 in the control group (P < 0.05). The exclusive breast-feeding rate at end of three months was 88% in the KMC group compared to 72% in the control group (P < 0.05). KMC improved physical growth, breastfeeding rates and was well accepted by both mothers and nursing staff.

This study investigates the effect of a modest weight loss either by a calorie restricted diet or mainly by increased physical exercise on health related quality of life (HRQoL) in overweight-to-obese and inactive postmenopausal women. We hypothesize that HRQoL improves with weight loss, and that exercise-induced weight loss is more effective for this than diet-induced weight loss. The SHAPE-2 trial was primarily designed to evaluate any additional effect of weight loss by exercise compared with a comparable amount of weight loss by diet on biomarkers relevant for breast cancer risk. In the present analysis we focus on HRQoL. We randomly assigned 243 eligible women to a diet (n = 97), exercise (n = 98), or control group (n = 48). Both interventions aimed for 5-6 kg weight loss. HRQoL was measured at baseline and after 16 weeks by the SF-36 questionnaire. Data of 214 women were available for analysis. Weight loss was 4.9 kg (6.1%) and 5.5 kg (6.9%) with diet and exercise, respectively. Scores of the SF-36 domain 'health change' increased significantly by 8.8 points (95% CI 1.6;16.1) with diet, and by 20.5 points (95% CI 13.2;27.7) with exercise when compared with control. Direct comparison of diet and exercise showed a statistically significantly stronger improvement with exercise. Both intervention groups showed a tendency towards improvements in most other domains, which were more pronounced in the exercise group, but not statistically different from control or each other. In a randomized trial in overweight-to-obese and inactive postmenopausal women a comparable 6%-7% weight loss was achieved by diet-only or mainly by exercise and showed improvements in physical and mental HRQoL domains, but results were not statistically significant in either the diet or exercise group. However, a modest weight loss does lead to a positive change in self-perceived health status. This effect was significantly larger with exercise-induced weight loss than with comparable diet-induced weight loss. ClinicalTrials.gov NCT01511276.

Weight loss among female health care workers- a 1-year workplace based randomized controlled trial in the FINALE-health study

PubMed Central

2012-01-01

Background Weight management constitutes a substantial problem particularly among groups of low socio-economic status. Interventions at work places may be a solution, but high quality worksite interventions documenting prolonged weight loss are lacking. This paper presents results of an intervention aimed to achieve a 12 months weight loss among overweight health care workers. Methods Ninety-eight overweight female health care workers were randomized into an intervention or a reference group. The intervention consisted of diet, physical exercise and cognitive behavioral training during working hours 1 hour/week. The reference group was offered monthly oral presentations. Several anthropometric measures, blood pressure, cardiorespiratory fitness, maximal muscle strength, and musculoskeletal pain were measured before and after the 12-months intervention period. Data were analyzed by intention-to-treat analysis. Results The intervention group significantly reduced body weight by 6 kg (p < 0.001), BMI by 2.2 (p < 0.001) and body fat percentage by 2.8 (p < 0.001). There were no statistical reductions in the control group, resulting in significant differences between the two groups over time. Conclusions The intervention generated substantial reductions in body weight, BMI and body fat percentage among overweight female health care workers over 12 months. The positive results support the workplace as an efficient arena for weight loss among overweight females. Trial registration NCT01015716. PMID:22871173

Although obesity causes many adverse health consequences, modest weight loss reduces the incidence. There are effective interventions that help people to lose weight but weight regain is common and long term maintenance remains a critical challenge. As a high proportion of the population of most high and middle income countries are overweight, there are many people who would benefit from weight loss and its maintenance. Therefore, we need to find effective low cost scalable interventions to help people achieve this. One such intervention that has shown promise is regular self-weighing, to check progress against a target, however there is no trial that has tested this using a randomised controlled design (RCT). The aim of this RCT is to evaluate the effectiveness and cost effectiveness of a brief behavioural intervention delivered by non-specialist staff to promote regular self-weighing to prevent weight regain after intentional weight loss. A randomised trial of 560 adults who have lost ≥ 5 % of their initial body weight through a 12 week weight loss programme. The comparator group receive a weight maintenance leaflet, a diagram representing healthy diet composition, and a list of websites for weight control. The intervention group receive the same plus minimally trained telephonists will ask participants to set a weight target and encourage them to weigh themselves daily, and provide support materials such as a weight record card. The primary outcome is the difference between groups in weight change from baseline to 12 months. If effective, this study will provide public health agencies with a simple, low cost maintenance intervention that could be implemented immediately. ISRCTN52341938 Date Registered: 31/03/2014.

Self-monitoring is part of many weight-loss programs and is widely accepted as effective. However, there is a lack of research related to the efficacy of various self-monitoring instruments in meeting the needs of individuals with limited mobility or access to healthcare providers, especially those with limited education living in rural settings. This study examined the efficacy of using self-monitoring diaries in a weight loss program targeting chronically ill and obese rural-dwelling adults. A community-based intervention program using a pretest and posttest design examined the effect of using self-monitoring diaries on weight loss. Fifty participants were enrolled from the chronic disease clinic of a district health center with limited medical resources in a remote village in southwestern Taiwan. All participants were diagnosed with diabetes and/or hypertension, had body mass indices between 27 and 32 kg/m, and had a minimum educational level of junior high school. Mean participant age was 43.7 years. Participants were randomly assigned to the intervention or control group. All attended a mandatory 12-week weight loss program. The intervention group received instructions on how to record diet and exercise details in a structured, graphics-based diary provided by the researchers. Body weight and percentage of body fat were measured before and after the program, and data were analyzed by chi-square and ANCOVA. The intervention group significantly lost more weight than the control group (5.7 kg vs. 2.1 kg; p < .05). The participants of 88% in the intervention group lost 5% or more of their baseline weight greater than the 23% in the control group. Both groups achieved the mean of body fat reductions by comparing pretest and posttest. Self-monitoring diaries can have a significant impact on weight loss in individuals living in rural communities. Healthcare providers and health promotion agencies can use the suggested checklist method to improve weight loss promotion programs in isolated rural communities with limited medical resources.

To examine whether a preoperative cognitive behavioural therapy (CBT) intervention exceeds usual care in the improvements of dysfunctional eating behaviours, mood, affective symptoms and body weight 1 year after bariatric surgery. This is a 1-year follow-up of a single centre parallel-group randomised controlled trial ( http://clinicaltrials.gov/ct2/show/NCT01403558). A total of 80 (55 females) patients mean (SD) age 44 (10) years were included. The intervention group received 10 weeks of CBT prior to bariatric surgery, and the control group received nutritional support and education. Both groups were assessed at baseline (T0), post CBT intervention/preoperatively (T1), and 1 year postoperatively (T2). Using a mixed modelling statistical approach, we examined if the CBT group improved more across time than the control group. Our hypothesis was not supported as both groups had comparable improvements in all outcomes except for anxiety symptoms. Body weight declined by 30.2 % (37.3 kg) in the CBT group and by 31.2 % (40.0 kg) in the control group from baseline to follow-up, p = 0.82. There were statistically significant reductions in anxiety and depression symptoms in the CBT group between T0 and T1 and between T1 and T2 for depression only. However, in the control group, the anxiety score did not change significantly. The CBT group showed an earlier onset of improvements in all eating behaviours and affective symptoms than the control group. The 10-week CBT intervention showed beneficial effects preoperatively, but the non-significant group differences postoperatively indicate a genuine effect of surgery.

To compare the effects of a low-carbohydrate (LC) diet with those of a low-fat (LF) diet on weight loss and serum lipids in overweight adolescents. A randomized, controlled 12-week trial. Atherosclerosis prevention referral center. Random, nonblinded assignment of participants referred for weight management. The study group (LC) (n = 16) was instructed to consume <20 g of carbohydrate per day for 2 weeks, then <40 g/day for 10 weeks, and to eat LC foods according to hunger. The control group (LF) (n = 14) was instructed to consume <30% of energy from fat. Diet composition and weight were monitored and recorded every 2 weeks. Serum lipid profiles were obtained at the start of the study and after 12 weeks. The LC group lost more weight (mean, 9.9 +/- 9.3 kg vs 4.1 +/- 4.9 kg, P <.05) and had improvement in non-HDL cholesterol levels (P <.05). There was improvement in LDL cholesterol levels (P <.05) in the LF group but not in the LC group. There were no adverse effects on the lipid profiles of participants in either group. The LC diet appears to be an effective method for short-term weight loss in overweight adolescents and does not harm the lipid profile.

Preclinical studies have implicated brain-derived neurotrophic factor (BDNF) in the regulation of eating behavior and body weight. As reviewed in this report, prior studies of BDNF levels in anorexia nervosa have yielded variable results, perhaps reflecting effects of malnutrition and psychiatric comorbidity. The goal of the current report was to assess plasma BDNF as a biomarker in weight-recovered individuals with a history of anorexia nervosa (ANWR). Study groups included women meeting criteria for ANWR and healthy female controls. Participants were in a normal weight range, free of current major psychiatric disorder, and free of medication. Self-ratings included eating disorder symptoms, depression and anxiety. Plasma BDNF levels were measured by enzyme linked immunoassay. Plasma BDNF levels were not significantly different for ANWR and control groups. Plasma BDNF levels were inversely correlated with anxiety ratings in controls (p<0.02) but not in the ANWR group. This report provides new evidence that circulating BDNF concentrations do not differ in healthy controls and ANWR free of psychiatric comorbidity. Additionally, the data provide new information on the relationship between plasma BDNF and anxiety in these two study groups. Copyright © 2016 Elsevier Inc. All rights reserved.

Computer-assisted dieting: effects of a randomised controlled intervention.

Schroder, Kerstin E E

2010-06-01

In this pilot study, the effects of two computer-assisted dieting (CAD) interventions on weight loss and blood chemistry were examined among overweight and obese adults. Participants (91 community members, average age 42.6 years) were randomly assigned to CAD-only (a single-session introduction and provision of a dieting software, n = 30), CAD plus an additional four-session self-management group training (CAD+G, n = 31) and a waitlist control group whose members were randomised into the two interventions at the 3-month follow-up (n = 30). A three (group)-by-two (time) repeated measures ANOVA revealed no significant group by time interaction during the initial 3-month period. However, the two intervention groups combined showed a significant, though moderate weight loss relative to the control group. Further, although a general improvement was found with regard to the lipid panel results during the first 3 months of the trial, the treatment by time interaction was not significant. A comparison of the developments in the two intervention groups during the 3- to 6-month follow-up time period revealed a tendency towards greater weight regain in the CAD-only condition. The evidence suggests that CAD supports initial weight loss; however, additional self-management training might be necessary to support maintenance.

To explore the growth pattern of appropriate for gestational age (AGA) infants of mother with gestational diabetes mellitus (GDM). The objects of this study were offspring of women who delivered in our hospital from January to December 2011. The GDM group included 70 AGA infants (36 male cases and 34 female cases) of mother with GDM. The control group included 154 AGA infants (66 male cases and 88 female cases) of women with normal glucose tolerance. The data of demographic characteristics of mothers of two groups were collected. Body weight and length of infants in two groups were measured at 3, 6 and 12 months age respectively. Body mass index (BMI), weight and height gain during infancy (0-3 months, 3-6 months and 6-12 months) of infants in two groups were also calculated. Body weight, length and BMI of male AGA infants in GDM group were less than that of control group at 3 months and 6 months age, but more than that of control group at 12 months age, however, there were no significant differences between two group(P>0.05). The weight and height gain during infancy (0-3 months, 3-6 months) of male AGA infants in GDM group were lower than that of control group, but the difference was statistically significant only at 3-6 months[(1.1±0.4) vs (1.4±0.4) kg, P=0.040; (4.9±2.3) vs (6.3±1.2) cm, P=0.026]. The weight and height gain during infancy (6-12 months) of male AGA infants of gestational diabetic mothers were higher than that of control group, but the difference was not statistically significant[(2.1±0.5) vs (1.8±0.5) kg, P=0.361; (8.4±1.3) vs (7.8±1.4) cm, P=0.464]. Male infants of gestational diabetic mothers grew slowly during their infancy of 0-6 months, and then their growth became increasingly fast, which suggested that the influence of intrauterine hyperglycemia environment of GDM mothers on fetal growth might continue after birth.

Since the 1950s, the problem of how to evaluate creativity has been addressed in studies on the definition of measurement criteria and on the relationship between intelligence and creative thinking. Many revealed cognitive and relational disorders in preterm infants, particularly in preterm very low birth weight infants (birth weight <1500 g) and in infants with serious complications. This study describes the development of creative thinking in a group of children born preterm. The study sample was 43 children (21 males, 22 females; age range 6-11 years), regularly attending school, born with low birth weight (1050-2450 g) at 29-32 weeks gestational age, and compared with a control group with birth weight >2500 g. The test battery included: Torrance Test of Creative Thinking (TCTT); WISC-R intelligence test; Goodenough Human Figure Drawing Test. Statistical analysis (Mann-Whitney U test) showed a statistically significant difference (P>0.05) between the 2 groups; scores for figure originality, figure fluidity and figure elaboration were consistently higher in the control group. Within the low birth weight group, there was a significant correlation (Spearman r) between verbal IQ and verbal fluidity and verbal flexibility subscale scores and between IQ performance and figure elaboration. Scores on the figure drawing tests showed higher creative ability in the control group. In children born preterm with low birth weight, emotive dynamics and flow of affection may influence the channels of communication between child and family. The low figure originality subscale scores support the hypothesis that psychodynamic and relational factors (worry about the preterm condition, overprotective behaviour by parents and others) could lead to diminished autonomy, flexibility and manipulatory interest in the child.

To determine the effects of dietary consumption of milled flaxseed or flaxseed oil on glycemic control, n-3 fatty acid status, anthropometrics, and adipokines in individuals with type 2 diabetes. Thirty-four participants were randomized into a parallel, controlled trial. The participants were adults with type 2 diabetes (age 52.4 +/- 1.5 years, body mass index 32.4 +/- 1.0 kg/m(2), n = 17 men and 17 women). Participants consumed a selection of bakery products containing no flax (control group [CTL], n = 9), milled flaxseed (FXS, n = 13; 32 g/d), or flaxseed oil (FXO, n = 12; 13 g/d) daily for 12 weeks. The FXS and FXO groups received equivalent amounts of alpha-linolenic acid (ALA; 7.4 g/day). The primary outcome measures were fasting plasma hemoglobin A(1c), glucose, insulin, and phospholipid fatty acid composition. The secondary outcome measures were fasting circulating leptin and adiponectin, as well as body weight, body mass index, and waist circumference. Dietary intake assessment and calculations for homeostasis model assessment for insulin resistance and quantified insulin sensitivity check were also completed. The FXS and FXO groups had increases in plasma phospholipid n-3 fatty acids (ALA, eicosapentaenoic acid [EPA], or decosapentaenoic acid [DPA], but not docosahexaenoic acid), and the FXO group had more EPA and DPA in plasma phospholipids compared to the FXS group. All groups had similar caloric intakes; however, the CTL group experienced a 4% weight gain compared to baseline (p < 0.05), while both flax groups had constant body weights during the study period. All other parameters, including glycemic control, were unchanged by dietary treatment. Milled FXS and FXO intake does not affect glycemic control in adults with well-controlled type 2 diabetes. Possible prevention of weight gain by flax consumption warrants further investigation.

The experiment was conducted to compare the effect of different selenium sources on the expression of glutathione peroxidase 1 (GPx1) and iodothyronine deiodinase 1 (Dio1) mRNA in mice by quantitative real-time PCR. A total of 60 male Kunming mice at average body weight of 20 g were allotted to three groups in a randomized complete block design, namely two treatments and one control. Mice in Group 1 were fed a basal diet as control, while mice in Groups 2 and 3 were fed the basal diet supplemented with 0.1mg/kg selenium as sodium selenite or selenized yeast, respectively. Whole feeding experiment lasted for 30 d. At the end of the feeding trial, liver mRNA levels of GPx1 and Dio1 were determined by quantitative real-time PCR, as well as growth performance, body composition, blood and GPx activity were determined. The results showed that no significant differences in overall growth performance and body composition, including body weight, body length, heart weight, kidney weight and liver weight, were found between the experimental groups (P>0.05). Blood GPx activity increased in all of the selenium supplemented groups compared with control group (P<0.01). However, blood GPx activity in selenized yeast group was higher than that in sodium selenite group (P<0.05). Liver mRNA levels of GPx1 and Dio1 also increased in the two selenium supplemented groups compared with the control group (P<0.05), while there was no significant difference between the sodium selenite and selenized yeast groups (P>0.05). In conclusion, selenium increased the mRNA expression of GPx1 and Dio1 genes in murine liver, and there was no significant difference between the organic or inorganic form of selenium used.

Does an intensive weight reduction programme prior to IVF increase live birth rates for infertile obese women? An intensive weight reduction programme resulted in a large weight loss but did not substantially affect live birth rates in obese women scheduled for IVF. Among obese women, fertility and obstetric outcomes are influenced negatively with increased risk of miscarriage and a higher risk of maternal and neonatal complications. A recent large randomized controlled trial found no effect of lifestyle intervention on live birth in infertile obese women. A prospective, multicentre, randomized controlled trial was performed between 2010 and 2016 in the Nordic countries. In total, 962 women were assessed for eligibility and 317 women were randomized. Computerized randomization with concealed allocation was performed in the proportions 1:1 to one of two groups: weight reduction intervention followed by IVF-treatment or IVF-treatment only. One cycle per patient was included. Nine infertility clinics in Sweden, Denmark and Iceland participated. Women under 38 years of age planning IVF, and having a BMI ≥30 and <35 kg/m2 were randomized to two groups: an intervention group (160 patients) with weight reduction before IVF, starting with 12 weeks of a low calorie liquid formula diet (LCD) of 880 kcal/day and thereafter weight stabilization for 2-5 weeks, or a control group (157 patients) with IVF only. In the full analysis set (FAS), the live birth rate was 29.6% (45/152) in the weight reduction and IVF group and 27.5% (42/153) in the IVF only group. The difference was not statistically significant (difference 2.2%, 95% CI: 12.9 to -8.6, P = 0.77). The mean weight change was -9.44 (6.57) kg in the weight reduction and IVF group as compared to +1.19 (1.95) kg in the IVF only group, being highly significant (P < 0.0001). Significantly more live births were achieved through spontaneous pregnancies in the weight reduction and IVF group, 10.5% (16) as compared to the IVF only group 2.6% (4) (P = 0.009). Miscarriage rates and gonadotropin dose used for IVF stimulation did not differ between groups. Two subgroup analyses were performed. The first compared women with PCOS in the two randomized groups, and the second compared women in the weight reduction group reaching BMI ≤ 25 kg/m2 or reaching a weight loss of at least five BMI units to the IVF only group. No statistical differences in live birth rates between the groups in either subgroup analysis were found. The study was not powered to detect a small increase in live births due to weight reduction and was not blinded for the patients or physician. Further, the intervention group had a longer time to achieve a spontaneous pregnancy, but were therefore slightly older than the control group at IVF. The study only included women with a BMI lower than 35 kg/m2. The study suggests that weight loss for obese women (BMI: 30-34.9 kg/m2) may not rectify the outcome in IVF cycles, although a significant higher number of spontaneous conceptions occurred in the weight loss group. Also, the study suggests that intensive weight reduction with LCD treatment does not negatively affects the results. The study was funded by Sahlgrenska University Hospital (ALFGBG-70 940), Merck AB, Solna, Sweden (an affiliate of Merck KGaA, Darmstadt, Germany), Impolin AB, Hjalmar Svensson Foundation and Jane and Dan Olsson Foundation.

There is a scarcity of resources and studies that utilize targeted weight management interventions to engage parents via mHealth tools targeting obese children and adolescents with mild intellectual disabilities (MIDs) extended from school to a home setting. To test the feasibility and acceptability of a school-based weight program (SBWMP) involving parents via mHealth tools designed to reduce weight, enhance knowledge and adopt healthy lifestyles, and thereby achieve better psychosocial well-being among children and adolescents with MIDs. Four special schools were randomly assigned as intervention or control schools. Students from the intervention group (n = 63) were compared to those in the control group (n = 52), which comprised those with usual school planned activities and no parental involvement. Demographics were considered as covariates in a general linear model, an ordinal regression model and a binary logistic regression model analyzing the relationships between the SBWMP and the outcome variables at baseline (T0) and six months later (T1). Body weight, body mass index, and triceps and subscapular skinfold thickness were lower in the intervention group compared to the control group, although the differences were not statistically significant. There was a positive and direct impact of the SBWMP on students’ health knowledge and psychological impacts in the intervention group. The SBWMP extended to the home involving parents via mHealth tools is a feasible and acceptable program for this group with MIDs and their parents. PMID:28981460

A randomized controlled trial of brief interventions for body dissatisfaction.

PubMed

Wade, Tracey; George, Wing Man; Atkinson, Melissa

2009-10-01

The authors examined the relative effectiveness of 3 different approaches to the experience of body dissatisfaction compared to a control and ruminative attention control condition, with respect to increasing weight and appearance satisfaction. One hundred female undergraduates (mean age = 24.38, SD = 9.39) underwent a body dissatisfaction induction procedure, which significantly decreased levels of weight and appearance satisfaction. Participants were then randomized, 20 to each of 5 groups: control, ruminative attention control, acceptance, distraction, and cognitive dissonance. With the exception of the control group, participants were briefly trained in their assigned technique and were asked to practice this over the next 5 min while repeated measures of weight and appearance satisfaction were recorded. Acceptance, cognitive dissonance, and distraction were superior to both control conditions in increasing weight satisfaction and were superior to a control condition in improving appearance satisfaction. Only acceptance was superior in improving appearance satisfaction compared to a ruminative attention control. The evidence suggests that acceptance is a promising approach to investigate further with respect to its efficacy for reducing body dissatisfaction. (c) 2009 APA, all rights reserved.

Gastric bypass is the most popular technique in obesity therapy. We hypothesize that bypass surgery can help to control the body weight in morbid obesity, and this effect can be enhanced by vagus dissection. Thirty-six Wistar rats were used in this investigation. They were randomly allocated into six groups. Rats in the gastric bypass group (GB1 and GB2) and the bypass with vagus dissection group (VD1 and VD2) received surgery. Rats in the control group (CO1 and CO2) received sham operation. Twenty days later, rats in the CO1, GB1, and VD1 groups were killed and data on body weights, food intakes, fasting glucose, plasma ghrelin and leptin levels, and GHS-R1a and leptin receptor protein expression in the hypothalamus were collected and summarized. One hundred days later, rats in the CO2, GB2, and VD2 groups were also killed and the same experiments were repeated. Body weights of rats were 258 +/- 4.2 and 232 +/- 2.4 g in the GB1 and VD1 groups, respectively, much lower than the CO1 group (303 +/- 6.9 g). Body weights of rats were 316 +/- 12.3 and 315 +/- 10.3 g in the GB2 and VD2 groups, respectively, much lower than the CO2 group. Food intake in the VD1 group was lower than in the GB1 group, while there were no statistical differences between the VD2 and GB2 groups. Fasting glucose in the GB1 and GB2 groups was much lower than the CO1 and CO2 groups. Plasma ghrelin concentrations were much lower in the GB1 and VD1 groups compared to the CO1 group. One hundred days after surgery, the ghrelin concentrations in the GB2 and VD2 groups were also much lower than the CO2 group. Leptin concentrations decreased significantly with weight loss after bypass surgery. GHS-R1a protein expression in the hypothalamus was much lower in the GB1 and VD1 groups compared to the CO1 group. GHS-R1a protein expressions in the GB2 and VD2 groups were lower than the CO2 group. There were no statistical differences in leptin receptor expression in the hypothalamus (not shown). Vagus nerve dissection is effective on body weight control in the early stage, but not in the long term. The hypothalamus is important in weight control by modulating ghrelin and leptin expressions. Bypass surgery can modulate the expression of ghrelin and its receptor. Leptin is also modulated by bypass surgery.

Middle-Eastern immigrants constitute a growing proportion of the Swedish population and are at high risk for Type 2 diabetes. This calls for a more proactive preventive approach for dealing with diabetes risk in this target group. The aim was to test the effect of a culturally adapted lifestyle intervention programme on changes in lifestyle habits and cardio-metabolic outcomes comparing an intervention group with a control group receiving usual care. Citizens of Malmö, Sweden born in Iraq and at high risk for Type 2 diabetes (n=636) were invited. Participation rate was 15.1%. In all, 96 participants were randomized to the intervention group (n=50) or to the control group (n=46). The intervention group was offered seven group sessions addressing healthy diet and physical activity including one cooking class. Changes in body weight, physical activity levels and cardio-metabolic outcomes were evaluated using linear mixed-effects models. The mean follow-up time was 3.9 and 3.5months in the intervention and control groups, respectively. The drop-out rate from baseline to the last visit was 30.0% in the intervention group (n=15) and 30.4% in the control group (n=14). The mean insulin sensitivity index increased significantly at follow-up in the intervention group compared to the control group (10.9% per month, p=0.005). The intervention group also reached a significant reduction in body weight (0.4% per month, p=0.004), body mass index (0.4% per month, p=0.004) and LDL-cholesterol (2.1% per month, p=0.036) compared to the control group. In total, 14.3% in the intervention group reached the goal to lose ≥5% of body weight versus none in the control group. This culturally adapted lifestyle intervention programme shows a beneficial effect on insulin action, body weight reduction, as well as LDL-cholesterol reduction, in Middle-Eastern immigrants. The programme adapted to resources in primary health care provides tools for improved primary prevention and reduced cardio-metabolic risk in this high-risk group for Type 2 diabetes.

In Islamic religion, daytime fasting during the month called Ramadan is an annual practice. In this study, we aimed to investigate the effect of Ramadan fasting and maternal hypoalbuminaemia on neonatal growth parameters. A prospective case-control study was conducted in Diyarbakir and Istanbul, Turkey. The sample size of fasting group was 168 and that of non-fasting group was 170. Demographic characteristics, obstetrics ultrasonographic findings and laboratory parameters of the participants were recorded. Neonatal anthropometric parameters and placental weight were noted. The mean placental weight was significantly higher in the fasting group (p = 0.037). Also, in the fasting group, pregnant women with hypoalbuminaemia had significantly higher placental weight (p = 0.009). In conclusion, the mean placental weight in the fasting group was significantly higher. Also a significant correlation between placental weight and maternal serum albumin level was observed in the fasting group.

Most subjects regain weight after weight loss due to compensatory adaptations finalized to maintain stable body energy stores. Green tea (GT) preparations, which help maintain energy expenditure while dieting could be a useful strategy to facilitate weight maintenance. The usefulness of GT preparations in weight maintenance has been poorly studied so far with conflicting results. This study evaluated if a supplement of GSP and piperine helps obese women to maintain the weight loss obtained with a 3-month lifestyle intervention. In a randomized placebo-controlled study, we examined whether a highly bioavailable GT extract may counteract weight regain after weight loss. Forty obese women (age 50.1 ± 10.1 years, Body Mass Index (BMI) 36.3 ± 2.7 kg/m(2)) underwent a 3-month lifestyle intervention. At the end of the intervention, the women were randomized in two groups for the weight-maintenance phase: 20 of them were prescribed twice a day, for 3 months, with a formula containing 150 mg/dose of Greenselect Phytosome® and 15 mg/dose of pure piperine (GSP group), and 20 were given placebo (P group). Anthropometric measures and body composition were measured before (V-3) and after lifestyle intervention (V0), 1 (V1), 2 (V2), and 3 (V3) months after prescribing supplements and 3 months following the discontinuation of supplements (V6). Lifestyle intervention induced a significant weight reduction in both groups with similar weight change (-6.2 ± 2.6 in GSP group vs. -4.8 ± 3.1 % in P group). In the GSP group, V1 in comparison to V0, had further reduction in weight and fat mass, which remained stable at V2 and V3 and increased at V6. In the P group, weight and fat mass increased from V2 onwards. Weight changes in GSP group and P group from V0 to V3 were -1.0 kg (95 % CI -2.5 to +0.5) and + 0.3 kg (95 % CI -0.9 to +1.6), respectively. The proportion of women with weight loss ≥ 5 % was greater in the GSP group than in the P group (75 % vs. 45 % at V1, and 60 % vs. 30 % at V6, p < 0.05 for both groups). Greenselect Phytosome® devoid of caffeine may have a clinical potential for the maintenance of weight after intentional weight loss. Clinicaltrials.gov NCT02542449 (September 2015).

To investigate whether walking or resistance training improves weight maintenance after weight loss when added to dietary counselling. Two months' weight reduction with very-low-energy-diet (VLED) followed by randomization into three groups (control, walking, resistance training) for 6 months' weight maintenance (WM) program and 23 months' unsupervised follow-up. During VLED and WM all groups received similar dietary counselling. The main inclusion criteria were BMI >30 kg/m(2), waist>100 cm and physical inactivity (exercise < or = once a week). Ninety healthy, obese (mean BMI 32.9 kg/m(2) and waist 112.5 cm), 35-50 y-old men started the study and 68 were measured at the end of the study. Weight and body composition assessed by underwater weighing. Exercise diaries and dietary records to assess energy balance. During VLED the mean body weight decreased from 106.0 (s.d. 9.9) kg to 91.7 (9.4) kg. Weight was regained mostly during follow-up and in the end of the study the mean weight in groups was 99.9-102.0 kg. Exercise training did not improve short or long-term weight maintenance when compared to the control group. However, resistance training attenuated the regain of body fat mass during WM (P=0.0l), but not during follow-up. In the combined groups the estimated total energy expenditure (EE) of reported physical activity was associated with less weight regain during WM. EE of 10.1 MJ/week was associated with maintaining weight after weight loss. EE of physical activity tended to decrease after WM in exercise groups due to poor long-term adherence to prescribed exercise. Energy intake seemed to increase during follow-up. Exercise training of moderate dose did not seem to improve long-term weight maintenance because of poor adherence to prescribed exercise.

THE ABSCOPAL EFFECT OF X IRRADIATION ON BONE GROWTH IN RATS

The abscopal effect of irradiation (that which is evident at a distance from the irradiated volume but within the same organism) was investigated in rats. It was possible to demonstrate the effects on growth locally and abscopally when x-ray doses of 400 and 800 r were delivered to the lower extremity and when 800 r was delivered to the knee alone. A distinction between abscopal effects after local irradiation and systemic effects after whole-body irradiation is discussed. The weights of control and irradiated animals were similar for the first 21 days, during which period they did not exhibit any untowardmore » effects of irradiation. However, after 21 days there was a decrease in weight gain, which persisted until the 72nd day. Group A (controls) was the heaviest group, with a mean weight of 412 g. Group B (800 r to the left hind extremity) had a mean weight of 378. Group C (400 r to the left hind extremity) and Group D (800 r to the left knee) exhibited mean weights of 391 and 394 g, respectively. Roentgenographic measurements revealed that all animals receiving irradiation had retardation in the growth of the irradiated tibiae, which were shorter than both the control and the contralateral (unirradiated) tibiae. Only the animals that had received 800 r to their leff hind extremity showed significant differences in the lengths of their unirradiated bones compared with the bones of the control animals of Group A, that is, a significant abscopal growth retardation. Although the abscopal effect appeared to be associated with the volume of tissue irradiated, the way this effect is mediated is not known. The weight gains of the animals demonstrated a strong association between decrease in weight gain, the volume of tissue irradiated, and the dose administered. The impaired weight gsin roughly paralleled the abscopal retardation of bone growth. The animals which received the highest dose of irradiation, 800 r, to the largest volume of tissue, 10% of the body volume, revealed the greatest deviation from the control group. It is concluded that irradiation effects in animals are composites of the responses of the whole organism to the injury, of the responses of local tissues, and vessels at their level of tissue organization, and of the responses of individual cells. All of these responses may be interdependent. The evidence indicates that a systemic inhibition of all bone growth and weight gain occurs when a sufficient volume of tissue is irradiated at a sufficiently high dosage. (BBB)« less

Adolescence is a critical time for the development of psychological well-being. Weight gain and the emergence of body image concerns during this period can lead to the development of negative psychological states. To explore this issue, we examined the relationship between weight control behavior (WCB; ie, trying to lose, gain, stay the same, or do nothing about weight) and levels of depression and self-esteem. Adolescents (508 boys, 502 girls; Mage  = 12.32 ± .88 years) completed a survey that assessed WCB, depression, and self-esteem. Descriptive discriminant analysis was used to analyze WCB group differences on psychological well-being. Multivariate post hoc analysis further examined group differences. Structure coefficients indicated the relative importance of each dependent variable in boys and girls. Results indicated that, among both sexes, WCB was significantly related to depression and self-esteem. Individuals trying to lose weight had lower levels of psychological well-being than the other groups. Adolescents trying to lose weight reported the lowest psychological well-being scores whereas those not doing anything to control weight reported the highest levels of psychological well-being. These findings have important implications for screening and education programs designed to monitor and support adolescent psychological well-being. © 2016, American School Health Association.

A study was undertaken in FELDA (Federal Land Development Authority) resettlement scheme areas in Pahang, Malaysia, to determine the effectiveness of group dietary counselling in motivating diabetic patients to achieve good dietary habits, and weight and diabetes control. Sixty-one non-insulin dependent diabetes mellitus (NIDDM) patients were randomly assigned to either the experimental or control group. The experimental group received six sessions of group dietary counselling over 5 months and the control group received mass media diabetes-educational program during the same period. The one hour group dietary counselling sessions discussed general knowledge of diabetes, food groups for meal planning, the importance of dietary fibre-rich foods, types of fat in food, exercise and weight control. The experimental group met monthly with a dietitian as a counsellor. Effectiveness was assessed by improvement in food choice, and decline in percentage glycated haemoglobin (total HbA1) or body mass index (BMI). Measurements were made at a baseline visit, every two months during the six month program, and six months afterwards. Patients in the experimental group improved their food choices, resulting in a healthier diet high in unrefined carbohydrates and dietary fibre rich foods, and low in fat. There were significant reductions of their percentage total HbA1 levels and BMI following the counselling sessions, which decreased further six months after the program compared with patients in the control group. Thus group dietary counselling is effective in motivating NIDDM patients to achieve better food choice, and related weight and glycaemic control in a Malaysian setting.

This study was conducted to investigate the effects of Sasa quelpaertensis bamboo and green tea on plasma and liver lipids, platelet aggregation, and erythrocyte membrane Na channels in ovariectomized (OVX) rats. Thirty female rats were OVX, and ten female rats were sham-operated at the age of 6 weeks. The rats were divided into four groups at the age of 10 weeks and fed the experiment diets: sham-control, OVX-control, OVX-bamboo leaves (10%), or OVX-green tea leaves (10%) for four weeks. Final body weight increased significantly in the OVX groups compared with that in the sham-control, whereas body weight in the OVX-green tea group decreased significantly compared with that in the OVX-control (P < 0.01). High density lipoprotein (HDL)-cholesterol level decreased in all OVX groups compared with that in the sham-control rats (P < 0.05) but without a difference in plasma total cholesterol. Plasma triglycerides in the OVX-green tea group were significantly lower than those in the sham-control or OVX-control group (P < 0.05). Liver triglycerides increased significantly in the OVX-control compared with those in the sham-control (P < 0.01) but decreased significantly in the OVX-green tea group compared with those in the OVX-control or OVX-bamboo group (P < 0.01). Platelet aggregation in both maximum and initial slope tended to be lower in all OVX rats compared with that in the sham-control rats but was not significantly different. Na-K ATPase tended to increase and Na-K cotransport tended to decrease following ovariectomy. Na-K ATPase decreased significantly in the OVX-green tea group compared with that in the OVX-control group (P < 0.01), and Na-K cotransport increased significantly in the OVX-bamboo and OVX-green tea groups compared with that in the OVX-control (P < 0.05). Femoral bone mineral density tended to be lower in OVX rats than that in the sham-control, whereas the green tea and bamboo leaves groups recovered bone density to some extent. The results show that ovariectomy caused an increase in body weight and liver triglycerides, and that green tea was effective for lowering body weight and triglycerides in OVX rats. Ovariectomy induced an increase in Na efflux via Na-K ATPase and a decrease in Na efflux via Na-K cotransport. Furthermore, consumption of green tea and bamboo leaves affected Na efflux channels, controlling electrolyte and body water balance. PMID:22586498

It is inconclusive that periodontitis is an independent risk factor for adverse pregnancy outcomes. This study aims to investigate the association between maternal periodontitis and preterm and/or low birth weight babies. This was a prospective cross-sectional study. After prior informed consent, 3500 postpartum mothers were selected from various hospitals in Tamil Nadu and categorized into the following groups: group-1 - Normal term normal birth weight ( n = 1100); Group-2 - Preterm normal birth weight ( n = 400); Group-3 - preterm low birth weight (PTLBW) ( n = 1000); and Group-4 - Normal term low birth weight ( n = 1000). Periodontal examination was done, and risk factors were ascertained by means of questionnaire and medical records. Comparison between case groups and control groups were done, odds ratio (OR) was calculated, and statistical significance were assessed by Chi-square tests. To control for the possible confounders, all variables with P < 0.05 were selected and entered into multivariate regression model, and OR and 95% confidence limits were again estimated. SPSS-15 software was used. Periodontitis was diagnosed in 54.8%, 52.3%, 53.8%, 59.4%, respectively. On comparison between the groups, none of periodontal parameters showed significant association except for the crude association observed in Group-4 for mild periodontitis (OR - 1.561; P = 0.000) and PTLBW. Periodontitis is not a significant independent risk factor, and obstetric factors contribute a major risk for preterm and/or low birth weight babies.

Background/Objectives: Direct evidence for the effects of vegetable intake on weight loss is qualified. The study aimed to assess the effect of higher vegetable consumption on weight loss. Subjects/Methods: A single blind parallel controlled trial was conducted with 120 overweight adults (mean body mass index=29.98 kg/m2) randomised to two energy deficit healthy diet advice groups differing only by doubling the serving (portion) sizes of vegetables in the comparator group. Data were analysed as intention-to-treat using a linear mixed model. Spearmans rho bivariate was used to explore relationships between percentage energy from vegetables and weight loss. Results: After 12 months, the study sample lost 6.5±5.2 kg (P<0.001 time) with no difference between groups (P>0.05 interaction). Both groups increased vegetable intake and lost weight in the first 3 months, and the change in weight was significantly correlated with higher proportions of energy consumed as vegetables (rho=–0.217, P=0.024). Fasting glucose, insulin and triglyceride levels decreased (P<0.001 time) and high-density lipoprotein cholesterol levels increased (P<0.001 time), with no difference between groups. Weight loss was sustained for 12 months by both groups, but the comparator group reported greater hunger satisfaction (P=0.005). Conclusions: Advice to consume a healthy low-energy diet leads to sustained weight loss, with reductions in cardiovascular disease risk factors regardless of an emphasis on more vegetables. In the short term, consuming a higher proportion of the dietary energy as vegetables may support a greater weight loss and the dietary pattern appears sustainable. PMID:24667750

The Stroop colour-naming task was used to investigate selective processing of eating, weight and shape related words in two groups of dieters, patients with anorexia nervosa, patients with bulimia nervosa and a group of non-dieting controls. 'Normal dieters' were not different from the non-dieting controls. Dieters with a history of features of an eating disorder but no diagnosis and the patients with anorexia nervosa, like the patients with bulimia nervosa, showed selective processing of information related to eating, weight and shape.

The aim of this study was to evaluate and compare the changes in body weight, body mass index (BMI), and body fat percentage (BFP) during the initial stages of fixed orthodontic treatment. The sample for this observational prospective study included 68 individuals with fixed orthodontic appliance in the age group of 18-25 years of both the sexes (25 males and 43 females). The control group consisted of 60 individuals (24 males and 36 females). The weight, BMI, and BFP were measured using a Body Composition Monitor at three points of time "T1" initial; "T2" after 1 month; and "T2" after 3 months. The results were tabulated and analyzed with the Statistical Package for the Social Sciences software. The mean changes between different parameters in both the study and control groups and between males and females in the study group was compared by using two-tailed unpaired student's t-test. The statistical significance is set atP ≤ 0.05. There was an overall decrease in the body weight, BMI, and BFP after 1 month in the study cohort, which was statistically significant compared to the control group (P < 0.0001). This was followed by an increase in the parameters after the end of the 3(rd) month. Comparison of the parameters between the study and control group at the start of the treatment and at the end of the 3(rd) month had no statistical significance. There was a marked variation in the changes of these parameters between males and females of the study group, which is statistically significant (<0.0001). There is a definite reduction in the weight, BMP, and BMI at the end of the first month followed by a gain of weight, but not at the initial point by the end of the 3(rd) month.

Abstract Background Pre‐operative weight loss has been consistently associated with increased post‐operative morbidity. The study aims to determine if pre‐operative oral nutritional supplements (ONSs) with dietary advice reduce post‐operative complications. Methods Single‐blinded randomized controlled trial. People with colorectal cancer scheduled for surgery with pre‐operative weight loss >1 kg/3–6 months were randomized by using stratified blocks (1:1 ratio) in six hospitals (1 November 2013–28 February 2015). Intervention group was given 250 mL/day ONS (10.1 KJ and 0.096 g protein per mL) and dietary advice. Control group received dietary advice alone. Oral nutritional supplements were administered from diagnosis to the day preceding surgery. Research team was masked to group allocation. Primary outcome was patients with one or more surgical site infection (SSI) or chest infection; secondary outcomes included percentage weight loss, total complications, and body composition measurements. Intention‐to‐treat analysis was performed with both unadjusted and adjusted analyses. A sample size of 88 was required. Results Of 101 participants, (55 ONS, 46 controls) 97 had surgery. In intention‐to‐treat analysis, there were 21/45 (47%) patients with an infection—either an SSI or chest infection in the control group vs. 17/55 (30%) in the ONS group. The odds ratio of a patient incurring either an SSI or chest infection was 0.532 (P = 0.135 confidence interval 0.232 to 1.218) in the unadjusted analysis and when adjusted for random differences at baseline (age, gender, percentage weight loss, and cancer staging) was 0.341 (P = 0.031, confidence interval 0.128 to 0.909). Pre‐operative percentage weight loss at the first time point after randomization was 4.1% [interquartile range (IQR) 1.7–7.0] in ONS group vs. 6.7% (IQR 2.6–10.8) in controls (Mann–Whitney U P = 0.021) and post‐operatively was 7.4% (IQR 4.3–10.0) in ONS group vs. 10.2% (IQR 5.1–18.5) in controls (P = 0.016). Conclusions Compared with dietary advice alone, ONS resulted in patients having fewer infections and less weight loss following surgery for colorectal cancer. We have demonstrated that pre‐operative oral nutritional supplementation can improve clinical outcome in weight losing patients with colorectal cancer. PMID:28052576

Intentional weight loss in obese older adults is a risk factor for muscle loss and sarcopenia. The objective was to examine the effect of a high whey protein-, leucine-, and vitamin D-enriched supplement on muscle mass preservation during intentional weight loss in obese older adults. We included 80 obese older adults in a double-blind randomized controlled trial. During a 13-wk weight loss program, all subjects followed a hypocaloric diet (-600 kcal/d) and performed resistance training 3×/wk. Subjects were randomly allocated to a high whey protein-, leucine-, and vitamin D-enriched supplement including a mix of other macro- and micronutrients (150 kcal, 21 g protein; 10×/wk, intervention group) or an isocaloric control. The primary outcome was change in appendicular muscle mass. The secondary outcomes were body composition, handgrip strength, and physical performance. Data were analyzed by using ANCOVA and mixed linear models with sex and baseline value as covariates. At baseline, mean ± SD age was 63 ± 5.6 y, and body mass index (in kg/m(2)) was 33 ± 4.4. During the trial, protein intake was 1.11 ± 0.28 g · kg body weight(-1) · d(-1) in the intervention group compared with 0.85 ± 0.24 g · kg body weight(-1) · d(-1) in the control group (P < 0.001). Both intervention and control groups decreased in body weight (-3.4 ± 3.6 kg and -2.8 ± 2.8 kg; both P < 0.001) and fat mass (-3.2 ± 3.1 kg and -2.5 ± 2.4 kg; both P < 0.001), with no differences between groups. The 13-wk change in appendicular muscle mass, however, was different in the intervention and control groups [+0.4 ± 1.2 kg and -0.5 ± 2.1 kg, respectively; β = 0.95 kg (95% CI: 0.09, 1.81); P = 0.03]. Muscle strength and function improved over time without significant differences between groups. A high whey protein-, leucine-, and vitamin D-enriched supplement compared with isocaloric control preserves appendicular muscle mass in obese older adults during a hypocaloric diet and resistance exercise program and might therefore reduce the risk of sarcopenia.

The anti-obesity effects of mushroom chitosan prepared from Flammulina velutipes were investigated using an animal model with diet-induced obesity. In this study, 5-week-old imprinting control region (ICR) mice were divided into six groups of 10 mice each and fed different diets based on the MF powdered diet (standard diet) for 6 weeks: standard diet control group, high-fat diet control group (induced dietary obesity) consisting of the standard diet and 20% lard, and mushroom chitosan groups consisting of the high-fat diet with mushroom chitosan added at 100, 500, 1,000, and 2,000 mg/kg body weight. On the final day of the experiment, mean body weight was 39.1 g in the high-fat control group and 36.3 g in the 2,000 mg/kg mushroom chitosan group, compared to 35.8 g in the standard diet control group. In the mushroom chitosan groups, a dose-dependent suppression of weight gain and marked improvements in serum triglycerides, total cholesterol, LDL-cholesterol, and HDL-cholesterol were found. The mushroom chitosan groups showed fewer and smaller fat deposits in liver cells than the high-fat diet control group, and liver weight was significantly reduced. Glutamic oxaloacetic transaminase (GOT) and glutamate pyruvic transaminase (GPT), which are indices of the hepatic function, all showed dose-dependent improvement with mushroom chitosan administration. These results suggested that mushroom chitosan acts to suppress enlargement of the liver from fat deposition resulting from a high-fat diet and to restore hepatic function. The lipid content of feces showed a marked increase correlated with the mushroom chitosan dose. These findings suggest the potential use of mushroom chitosan as a functional food ingredient that contributes to the prevention or improvement of dietary obesity by inhibiting digestion and absorption of fats in the digestive tract and simultaneously promotes lipolysis in adipocytes.

This open-label randomized controlled clinical trial compared the effect on glycaemic control and weight gain of repaglinide vs. gliclazide combined with bedtime NPH insulin in patients with Type 2 diabetes inadequately controlled with oral hypoglycaemic therapy [HbA1c>7.0% (DCCT aligned assay, normal range 4.6-6.2%)]. Eighty subjects with Type 2 diabetes were randomized to 13 weeks' open-label treatment with repaglinide 4 mg t.i.d. or gliclazide 160 mg b.i.d. in combination with bedtime NPH insulin (initial dose 0.5 units/kg). The fasting blood glucose (FBG) target was < or =6.0 mmol/l. Baseline characteristics were similar for age, sex, weight, BMI, FBG and HbA1c. Glycaemic control improved similarly in both groups-insulin/gliclazide by (mean) 1.0%, from 9.2 to 8.2% (P=0.001) and by 0.9%, from 9.4 to 8.5% in the insulin/repaglinide group (P=0.005) (P=0.83 between groups). Weight gain averaged (mean +/- sem) 4.1 +/- 0.5 and 3.4 +/- 0.4 kg in the insulin/gliclazide and insulin/repaglinide groups, respectively (P<0.0001 for both groups from baseline) (P=0.29 between groups). The mean number of hypoglycaemic episodes experienced per patient was 2.95 +/- 0.82 (insulin/gliclazide) and 2.3 +/- 0.52 (insulin/repaglinide) (P=0.81 between groups). Both treatments were associated with significant improvements in Diabetes Treatment Satisfaction [Diabetes Treatment Satisfaction Questionnaire-potential range 0 (min) to 36 (max)]; in the insulin/gliclazide group, by 4.9 +/- 1.1 points to 33.3 +/- 0.6 (P<0.0001) and by 3.0 +/- 0.9 points to 34.6 +/- 0.4 (P=0.0006) in the insulin/repaglinide group (P=0.29 between groups). Over 13 weeks, both repaglinide and gliclazide, when combined with bedtime NPH insulin produce similar significant improvements in glycaemic control (-1%) and similar weight gain.

The main objective of this study was to determine differences in postural control between obese and non-obese children. The study design was cross-sectional, prospective, between-subjects. Postural control variables were obtained from a group of obese children and a normal-weight control group under two different postural conditions: bipedal standing position with eyes open and bipedal standing with eyes closed. Variables were obtained for each balance condition using time domain and sway-density plot analysis of the center of pressure signals acquired by means of a force plate. Pairwise comparisons revealed significant differences between obese and normal-weight children in mean velocity in antero-posterior and medio-lateral directions, ellipse area and mean distance with both eyes open and eyes closed. Normal-weight subjects obtained lower values in all these variables than obese subjects. Furthermore, there were differences between both groups in mean peaks with eyes open and in mean time with eyes closed. Alterations were detected in the intermittent postural control in obese children. According to the results obtained, active anticipatory control produces higher center of pressure displacement responses in obese children and the periods during which balance is maintained by passive control and reflex mechanisms are of shorter duration.

To look for possible developmental effects in the offspring of jojoba meal-treated Wistar rats, and to distinguish between the effects of reduced food intake and the specific developmental effects of jojoba meal itself, mated female rats were divided into three groups of 20 rats. They received during gestation: (a) normal rodent food (control group); (b) normal rodent food supplemented with 3% defatted jojoba meal (jojoba group); or (c) normal rodent food pair-fed with the jojoba group (pair-fed group). The jojoba meal group showed approximately 30% inhibition of food intake. Ten rats from each group were killed on gestation day 21. Compared to the control group, foetal body weight was reduced in both the jojoba and pair-fed groups, with a greater reduction in the jojoba group. Skeletal ossification was retarded to the same extent in both the jojoba and pair-fed groups. The other 10 rats from each group were left to produce litters. Compared with controls, the body weight of the pups was lower in both the jojoba and pair-fed groups; the reduction was slightly greater in the jojoba group, but this difference disappeared after 1 week. The offspring showed no other abnormalities and reproduced normally. We conclude that, at the dose used, the retardation in foetal skeletal ossification, induced by jojoba meal supplementation during gestation, is due to food intake inhibition. Moreover, the lower birth weight of the young of jojoba-treated dams compared with the pair-fed group is merely due to a lower body weight gain during gestation.

Background Weight gain early after transplant is a risk factor for posttransplant metabolic syndrome (PTMS), cardiovascular events, and renal insufficiency. The impact of mammalian target of rapamycin inhibition on posttransplant weight gain and the development of PTMS components postliver transplantation were examined in a randomized, controlled study. Methods After a run-in period, patients (N = 719) were randomized at 30 ± 5 days posttransplant in a 1:1:1 ratio to 3 treatment groups: (i) everolimus (EVR) + reduced tacrolimus (TAC) (n = 245); (ii) TAC control (n = 243) or (iii) TAC elimination (n = 231). In this post hoc analysis, weight change at 12 and 24 months was compared between groups. Vital signs, lipids, and laboratory parameters at 12 and 24 months and rates of PTMS were assessed. Results Mean increase in weight from baseline was higher at month 12 in the TAC control arm (8.15 ± 9.27 kg) than in the EVR + reduced TAC (5.88 ± 12.60 kg, P = 0.056) and the TAC elimination arms (4.76 ± 9.94 kg, P = 0.007). At month 24, the TAC control arm displayed a significantly greater weight increase (9.54 ± 10.21 kg) than either the EVR + reduced TAC (6.69 ± 8.37 kg, P = 0.011) or the TAC elimination groups (6.01 ± 9.98 kg, P = 0.024). Rates of PTMS were similar for the EVR + reduced TAC (71.8%), TAC elimination (70.3%) and TAC control (67.4%) arms (P = NS). Conclusions EVR with reduced-exposure TAC attenuated weight gain at 1 and 2 years posttransplant compared with a standard TAC immunosuppression regimen. Rates of PTMS were comparable between EVR-containing and TAC control regimens. PMID:28817434

Many patients with schizophrenia suffer from metabolic symptoms and weight gain in which predispose them to obesity, diabetes, and cardiovascular problems. This trial examines the efficacy and safety of zonisamide on weight and body mass index in patients with schizophrenia being administered with atypical antipsychotics. In this 10-week, double blind randomized placebo controlled clinical trial, forty one patients with schizophrenia diagnosed according to DSM-IV-TR criteria who were taking a stable dose of atypical antipsychotic are allocated into one of the two groups of zonisamide or placebo group. Weight, body mass index, waist circumference, and adverse effects were assessed. The two groups were not statistically different regarding baseline characteristics on age, gender, education, diagnosis, weight, body mass index, daily cigarette smoking, and the duration of illness. After 10 weeks, the patients in the placebo group had significantly gained weight, while the patients in the zonisamide group lost weight (mean=1.9, SD=2.2 versus mean=-1.1 kg, SD=1.4). The changes of body mass index in the two groups were significantly different. Body mass index decreased in the zonisamide group (mean=-0.3, SD=0.4) while it increased in the placebo group (mean=2.2, SD=6.9). There was a significance difference between the two groups regarding waist circumference at the end of trial (P<0.0001), too. The waist increased in the placebo group while it decreased in the zonisamide group (mean=1.1, SD=1.7 versus mean=-0.7, SD=1.2, respectively), as well. The frequencies of adverse effects were not significantly different between the two groups and zonisamide was tolerated well. Zonisamide as an adjuvant treatment is tolerated well and markedly affect on the weight loss of patients with schizophrenia being treated with atypical antipsychotics. Copyright © 2013 Elsevier B.V.

In research settings, plant-based (vegan) eating plans improve diabetes management, typically reducing weight, glycemia, and low-density lipoprotein (LDL) cholesterol concentrations to a greater extent than has been shown with portion-controlled eating plans. The study aimed to test whether similar benefits could be found using weekly nutrition classes in a typical endocrinology practice, hypothesizing that a vegan eating plan would improve glycemic control, weight, lipid concentrations, blood pressure, and renal function and would do so more effectively than a portion-controlled eating plan. In a 20-week trial, participants were randomly assigned to a low-fat vegan or portion-controlled eating plan. Individuals with type 2 diabetes treated in a single endocrinology practice in Washington, DC, participated (45 starters, 40 completers). Participants attended weekly after-hours classes in the office waiting room. The vegan plan excluded animal products and added oils and favored low-glycemic index foods. The portion-controlled plan included energy intake limits for weight loss (typically a deficit of 500 calories/day) and provided guidance on portion sizes. Body weight, hemoglobin A1c (HbA1c), plasma lipids, urinary albumin, and blood pressure were measured. For normally distributed data, t tests were used; for skewed outcomes, rank-based approaches were implemented (Wilcoxon signed-rank test for within-group changes, Wilcoxon two-sample test for between-group comparisons, and exact Hodges-Lehmann estimation to estimate effect sizes). Although participants were in generally good metabolic control at baseline, body weight, HbA1c, and LDL cholesterol improved significantly within each group, with no significant differences between the two eating plans (weight: -6.3 kg vegan, -4.4 kg portion-controlled, between-group P=0.10; HbA1c, -0.40 percentage point in both groups, P=0.68; LDL cholesterol -11.9 mg/dL vegan, -12.7 mg/dL portion-controlled, P=0.89). Mean urinary albumin was normal at baseline and did not meaningfully change. Blood pressure changes were not significant. Weekly classes, integrated into a clinical practice and using either a low-fat vegan or portion-controlled eating plan, led to clinical improvements in individuals with type 2 diabetes.

Physical activity and healthy eating are of the utmost importance in treatment of obesity. However obese generally tend to have a sedentary lifestyle. Walking is a form of physical activity that is both simple and can be performed by everyone, but it requires an objective measurement. Number of steps taken during tracking can be recorded with the pedometer, a device used to measure the level of physical activity. We aimed to investigate whether or not using pedometers as a motivational technique to increase the level of physical activity in obese women has an impact on weight loss. Eighty-four obese women who are similar age referring to Ataturk University Faculty of Medicine Healthy Living Clinic, Turkey were randomly divided into two groups. Intervention group were given pedometers, and control group were prescribed similar diet and physical activity with a three-month follow-up plan without pedometers. Mean weight in pedometer group initially was 88.9 ± 8.4 kg, which decreased to 80.2 ± 8.7 kg after the programme. Mean weight in control group was 86.1 ± 9.2 kg at the beginning, and it decreased to 84.7 ± 8.8 kg after three months. It was observed in pedometer group that the mean number of steps 8817 ± 2725 steps/day at the beginning increased to mean 9716 ± 2811 steps/day at the end of the study. Weight, body mass index, body fat percentage and waist circumference measurements decreased more greatly in the pedometer when compared to the control group (p < 0.001). Pedometers may be recommended to obese patients to monitor and increase the level of physical activity and to promote weight loss.

Background Ligation of the left gastric artery (LLGA), which supplies the fundus of the stomach, may reduce the appetite hormone ghrelin, resulting in weight control. The aim of this study was to compare LLGA and sleeve gastrectomy (SG) in terms of postoperative outcomes in a rat model. Material/Methods Fifteen male Wistar albino rats, weighing >350 grams (range 350–525 grams), were enrolled in LLGA (N=5), SG (N=5), and control (N=5) groups. Blood samples were drawn preoperatively and also during the first and fourth week postoperatively to assay ghrelin and leptin hormone levels. Body weight was measured in each group. Results The maximum reduction in ghrelin level (41.5%) was found in the LLGA group. Considerable% total weight loss (TWL) (mean 24.1%) was observed in the SG group, and slight%TWL was noted in the control and LLGA groups (means of 0.1% and 2.1%, respectively). There was no significant difference in mean percent weight change between the LLGA and the SG groups (p=0.08). Blood sample analysis revealed no statistically significant changes in ghrelin or leptin levels between the groups (p=0.9 and p=0.3, respectively). Conclusions We present evidence that LLGA causes the same reduction in ghrelin hormone levels as SG at 4 weeks after surgery in a rat model. However, LLGA did not cause the same%TWL as SG. The mechanism of weight loss in SG is most likely due to restriction and to the effects of the procedure, rather than due to neurohormonal changes. PMID:28339424

A meta-analysis was carried out to (1) study the relation of the variation in feed intake and weight gain in broilers infected with Eimeria acervulina, Eimeria maxima, Eimeria tenella, or a Pool of Eimeria species, and (2) to identify and to quantify the effects involved in the infection. A database of articles addressing the experimental infection with Coccidia in broilers was developed. These publications must present results of animal performance (weight gain, feed intake, and feed conversion ratio). The database was composed by 69 publications, totalling around 44 thousand animals. Meta-analysis followed three sequential analyses: graphical, correlation, and variance-covariance. The feed intake of the groups challenged by E. acervulina and E. tenella did not differ (P>0.05) to the control group. However, the feed intake in groups challenged by E. maxima and Pool showed an increase of 8% and 5% (P<0.05) in relation to the control group. Challenged groups presented a decrease (P<0.05) in weight gain compared with control groups. All challenged groups showed a reduction in weight gain, even when there was no reduction (P<0.05) in feed intake (adjustment through variance-covariance analysis). The feed intake variation in broilers infected with E. acervulina, E. maxima, E. tenella, or Pool showed a quadratic (P<0.05) influence over the variation in weight gain. In relation to the isolated effects, the challenges have an impact of less than 1% over the variance in feed intake and weight gain. However, the magnitude of the effects varied with Eimeria species, animal age, sex, and genetic line. In general the age effect is superior to the challenge effect, showing that age at the challenge is important to determine the impact of Eimeria infection. Copyright © 2013 Elsevier B.V.

Maintaining weight loss is a major challenge in obesity treatment. Individuals often indicate that waning motivation prompts cessation of effective weight management behaviors. Therefore, a novel weight loss maintenance program that specifically targets motivational factors was evaluated. Overweight women (N=338; 19% African American) with urinary incontinence were randomized to lifestyle obesity treatment or control and followed for 18 months. All participants in lifestyle (N=226) received the same initial 6-month group behavioral obesity treatment and were then randomized to (1) a novel motivation-focused maintenance program (N=113) or (2) a standard skill-based maintenance approach (N=113). Weight assessed at baseline, 6 and 18 months. Both treatment groups (motivation-focused and skill-based) achieved comparable 18-month weight losses (-5.48% for motivation-focused vs -5.55% in skill-based, P=0.98), and both groups lost significantly more than controls (-1.51%; P=0.0012 in motivation-focused and P=0.0021 in skill-based). A motivation-focused maintenance program offers an alternative, effective approach to weight maintenance expanding available evidence-based interventions beyond traditional skill-based programs.

Self-weighing seems to have a primary role in weight-loss maintenance. The use of this strategy may help correct even slight weight regain and contribute to long-term weight stability. However, self-weighing has also been associated with negative psychological health consequences in specific subgroups. This study aimed to explore the use and the behavioral and psychological consequences of self-weighing in a group of weight-loss maintainers (WLoMs). We chose a qualitative design to conduct this investigation. Eighteen WLoMs were interviewed and compared to a matched comparison group of 18 participants with a lifelong normal stable weight (NSW). Analyses showed that most WLoMs needed regular self-weighing to be aware of their weight. The weight displayed on the scale helped WLoMs sustain the continuous efforts needed to maintain weight loss and also at times triggered corrective actions that were sometimes drastic. Weight changes generated both negative and positive affect among WLoMs, who could experience anxiety because of self-weighing or have their self-esteem impaired in the case of weight gain. In comparison, the NSW group rarely used self-weighing. They relied on a conscious way of living to control their weight and needed fewer strategies. NSW participants simply went back to their routine when they felt a slight increase in their weight, without experiencing consequences on their mood or self-esteem. Regular self-weighing as a component of weight-loss maintenance should be encouraged to help WLoMs regulate their food and physical activity, provided that potential consequences on psychological well-being, including self-esteem, are screened and addressed when needed.

An attempt was made to evaluate the oral doses of 9 g/kg-body weight of Albizzia anthelmintica Brong. Mimoaseae stem bark water extract and 9 g/kg body weight of B. aegyptiaca (L) Del. (Balanitaceae) fruit mesocarp water extract (traditionally used as an anthelmintic in the Sudan) compared with 20 mg/kg body weight (recommended dose) of albendazole against Fasciola gigantica adult worm (12 weeks old) in five groups each of three goats (6 month old). Group (I) uninfected control, group (II) infected untreated control, group (III, IV and V) infected and treated as mentioned above respectively. Based on the percentage reduction in fluke counts from the liver post mortum 2 weeks after treatment, the efficacy of the mentioned therapeutics was 95.5, 93.2 and 97.7%, respectively. The characteristic lesions of liver fasciolosis, egg/gm of faeces (EPG), packed cell volume (PCV), haemoglobin concentration, total red blood cells count (RBC), total white blood cells count (WBC) and oesinophil% were significantly different from control and treated groups (P<0.05).

Background The interactions between the gut microbiome and obesity have been extensively studied. Although the oral cavity is the gateway to the gut, and is extensively colonized with microbes, little is known about the oral microbiome in people with obesity. In the present study, we investigated the salivary microbiome in obese and normal weight healthy participants using metagenomic analysis. The subjects were categorized into two groups, obesity and normal weight, based on their BMIs. Methods We characterized the salivary microbiome of 33 adults with obesity and 29 normal weight controls using high-throughput sequencing of the V3–V4 region of the 16S rRNA gene (Illumina MiSeq). None of the selected participants had systemic, oral mucosal, or periodontal diseases. Results The salivary microbiome of the obesity group was distinct from that of the normal weight group. The salivary microbiome of periodontally healthy people with obesity had both significantly lower bacterial diversity and richness compared with the controls. The genus Prevotella, Granulicatella, Peptostreptococcus, Solobacterium, Catonella, and Mogibacterium were significantly more abundant in the obesity group; meanwhile the genus Haemophilus, Corynebacterium, Capnocytophaga, and Staphylococcus were less abundant in the obesity group. We also performed a functional analysis of the inferred metagenomes, and showed that the salivary community associated with obesity had a stronger signature of immune disease and a decreased functional signature related to environmental adaptation and Xenobiotics biodegradation compared with the normal weight controls. Discussion Our study demonstrates that the microbial diversity and structure of the salivary microbiome in people with obesity are significantly different from those of normal weight controls. These results suggested that changes in the structure and function of salivary microbiome in people with obesity might reflect their susceptibility to oral diseases. PMID:29576948

Weight loss studies were conducted in children without asthma have demonstrated a reduction in systemic inflammation. However, the impact of weight loss in the obese paediatric population with asthma has not been investigated. To measure the effects of weight loss on markers of systemic inflammation in obese children with bronchial asthma. Eighty obese children with bronchial asthma (42 boys, and 38 girls) with mean age 13.86 ± 3.21 years were divided into two equal groups. The training group received diet regimen, exercise training in addition to the medical treatment for two months, where the control group received the medical treatment only. There was a 17.5%, 15.5%, 22.4%, 14.1% and 15.9% reduction in mean values of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), interleukin-8 (IL-8), Leptin and body mass index (BMI) respectively and 38.7 % increase in mean values of adiponectin in the training group. While, there was a 0.7%, 9.0%, 2.8%, 1.6% and 1.2% increase in mean values of TNF-alpha, IL-6, IL-8, Leptin and BMI respectively and 3.9% decrease in mean values of adiponectin in the control group. The mean values of TNF-alpha, IL-6, IL-8, Leptin and BMI was decreased and adiponectin was increased significantly in the training group, however the results of the control group were not significant. Also, there were significant differences between both groups at the end of the study. Weight loss improves markers of systemic inflammation in obese Saudi children with bronchial asthma.

The purpose of this study was to evaluate the effects of massage on infant weight gain and exclusive maternal breast-feeding of an intervention that involved teaching mothers to massage their full-term infants. The sample included 100 healthy newborn infants who were receiving primary healthcare at 3 health centers in a low-income neighborhood of Santiago, Chile. The control group included 65 infants and the massage group included 35 infants. During their second well-child clinic visit, clinic nurses provided instruction to massage-group mothers about how to massage their infants, based on the methods of the Baby's First Massage program (http://www.babysfirstmassage.com/Scripts/default.asp). Mothers were encouraged to massage their infants for 10 to 15 minutes at least once a day, starting when their infants were 15 days old. There was no difference in the mean weights of the infants between the massage and control groups at baseline, but at age 2 months, massage group infants weighed significantly more than control-group infants. There were no weight differences between the 2 groups at age 4 months. There were no differences between the 2 groups on the incidence of exclusive maternal breast-feeding at age 2 or 4 months. The findings suggest that teaching mothers to massage their newborn infants may have a beneficial effect on the infant's early weight gain. There is a need for additional studies to evaluate the effect of maternal massage on other health and welfare outcomes for both mothers and infants.

Thirty-six crossbred calves (Holstein cross) of 5 days of age were used to study the effect of garlic extract feeding on their performance up to the age of 2 months (pre-ruminant stage). They were randomly allotted into treatment and control groups (18 numbers in each group). Performance was evaluated by measuring average body weight (BW) gain, feed intake (dry matter (DM), total digestible nutrient (TDN) and crude protein (CP)), feed conversion efficiency (FCE; DM, TDN and CP), faecal score, faecal coliform count and feeding cost. Diets were the same for the both groups. In addition, treatment group received garlic extract supplementation at 250 mg/kg BW per day per calf. Body weight measured weekly, feed intake measured twice daily, proximate analysis of feeds and fodders analysed weekly, faecal scores monitored daily and faecal coliform count done weekly. There was significant increase in average body weight gain, feed intake and FCE and significant decrease in severity of scours as measured by faecal score and faecal coliform count in the treatment group compared to the control group (P < 0.01). Feed cost per kilogramme BW gain was significantly lower in the treatment group compared to control group (P < 0.01). The results suggest that garlic extract can be supplemented to the calves for better performance.

Behavioural counselling with intensive follow-up for obesity is effective, but in resource-constrained primary care settings briefer approaches are needed. To estimate the clinical effectiveness and cost-effectiveness of an internet-based behavioural intervention with regular face-to-face or remote support in primary care, compared with brief advice. Individually randomised three-arm parallel trial with health economic evaluation and nested qualitative interviews. Primary care general practices in the UK. Patients with a body mass index of ≥ 30 kg/m 2 (or ≥ 28 kg/m 2 with risk factors) identified from general practice records, recruited by postal invitation. Positive Online Weight Reduction (POWeR+) is a 24-session, web-based weight management intervention completed over 6 months. Following online registration, the website randomly allocated participants using computer-generated random numbers to (1) the control intervention ( n  = 279), which had previously been demonstrated to be clinically effective (brief web-based information that minimised pressure to cut down foods, instead encouraging swaps to healthier choices and increasing fruit and vegetables, plus 6-monthly nurse weighing); (2) POWeR+F ( n  = 269), POWeR+ supplemented by face-to-face nurse support (up to seven contacts); or (3) POWeR+R ( n  = 270), POWeR+ supplemented by remote nurse support (up to five e-mails or brief telephone calls). The primary outcome was a modelled estimate of average weight reduction over 12 months, assessed blind to group where possible, using multiple imputation for missing data. The secondary outcome was the number of participants maintaining a 5% weight reduction at 12 months. A total of 818 eligible individuals were randomised using computer-generated random numbers. Weight change, averaged over 12 months, was documented in 666 out of 818 participants (81%; control, n  = 227; POWeR+F, n  = 221; POWeR+R, n  = 218). The control group maintained nearly 3 kg of weight loss per person (mean weight per person: baseline, 104.4 kg; 6 months, 101.9 kg; 12 months, 101.7 kg). Compared with the control group, the estimated additional weight reduction with POWeR+F was 1.5 kg [95% confidence interval (CI) 0.6 to 2.4 kg; p  = 0.001] and with POWeR+R was 1.3 kg (95% CI 0.34 to 2.2 kg; p  = 0.007). By 12 months the mean weight loss was not statistically significantly different between groups, but 20.8% of control participants, 29.2% of POWeR+F participants (risk ratio 1.56, 95% CI 0.96 to 2.51; p  = 0.070) and 32.4% of POWeR+R participants (risk ratio 1.82, 95% CI 1.31 to 2.74; p  = 0.004) maintained a clinically significant 5% weight reduction. The POWeR+R group had fewer individuals who reported doing another activity to help lose weight [control, 47.1% (64/136); POWeR+F, 37.2% (51/137); POWeR+R, 26.7% (40/150)]. The incremental cost to the health service per kilogram weight lost, compared with the control group, was £18 (95% CI -£129 to £195) for POWeR+F and -£25 (95% CI -£268 to £157) for POWeR+R. The probability of being cost-effective at a threshold of £100 per kilogram was 88% and 98% for POWeR+F and POWeR+R, respectively. POWeR+R was dominant compared with the control group. No harms were reported and participants using POWeR+ felt more enabled in managing their weight. The qualitative studies documented that POWeR+ was viewed positively by patients and that health-care professionals generally enjoyed supporting patients using POWeR+. Maintenance of weight loss after 1 year is unknown. Identifying strategies for longer-term engagement, impact in community settings and increasing physical activity. Clinically valuable weight loss (> 5%) is maintained in 20% of individuals using novel written materials with brief follow-up. A web-based behavioural programme and brief support results in greater mean weight loss and 10% more participants maintain valuable weight loss; it achieves greater enablement and fewer participants undertaking other weight-loss activities; and it is likely to be cost-effective.

Analyses of global trends indicate that childhood undernutrition is more prevalent in rural areas, and also that maternal education and decision-making power are among the key factors significantly associated with child growth. The present study comprised a controlled longitudinal study aiming to assess the effectiveness of nutrition education with respect to improving growth patterns of young children of less-literate, low income caregivers in a rural subsistence farming community. Caregivers in the intervention group (n = 52) attended a structured nutrition education programme, whereas the control group (n = 45) participated in sewing classes. Weights and lengths/heights were measured for children in the intervention and control groups every month for 1 year to assess changes in growth patterns. Repeated measures analysis of covariance was used to access differences between the two groups over time and across age groups. Variability in growth patterns of individual children and clustering of caregiver effects were controlled for during the statistical analysis. After 12 months, children in the intervention group had significant improvements in weight-for-age compared to the controls [mean (SD): 0.61 (0.15) versus -0.99 (0.16), P = 0.038]. Changes in height-for-age, weight-for-height and mid-upper arm circumference-for-age showed a positive trend for children in the intervention group. Changes in weight-for-height were statistically significant across age groups and negatively related to caregiver's age. Educating caregivers has the potential to improve young children's nutritional status and growth, especially among less literate populations where households subsist on what they produce. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

Evidence on the effectiveness of behavioral weight management programs often comes from uncontrolled program evaluations. These frequently make the assumption that, without intervention, people will gain weight. The aim of this study was to use data from minimal intervention control groups in randomized controlled trials to examine the evidence for this assumption and the effect of frequency of weighing on weight change. Data were extracted from minimal intervention control arms in a systematic review of multicomponent behavioral weight management programs. Two reviewers classified control arms into three categories based on intensity of minimal intervention and calculated 12-month mean weight change using baseline observation carried forward. Meta-regression was conducted in STATA v12. Thirty studies met the inclusion criteria, twenty-nine of which had usable data, representing 5,963 participants allocated to control arms. Control arms were categorized according to intensity, as offering leaflets only, a single session of advice, or more than one session of advice from someone without specialist skills in supporting weight loss. Mean weight change at 12 months across all categories was -0.8 kg (95% CI -1.1 to -0.4). In an unadjusted model, increasing intensity by moving up a category was associated with an additional weight loss of -0.53 kg (95% CI -0.96 to -0.09). Also in an unadjusted model, each additional weigh-in was associated with a weight change of -0.42 kg (95% CI -0.81 to -0.03). However, when both variables were placed in the same model, neither intervention category nor number of weigh-ins was associated with weight change. Uncontrolled evaluations of weight loss programs should assume that, in the absence of intervention, their population would weigh up to a kilogram on average less than baseline at the end of the first year of follow-up. © 2016 The Authors Obesity published by Wiley Periodicals, Inc. on behalf of The Obesity Society (TOS).

Rapid infant weight gain is associated with later obesity, but interventions to prevent rapid infant growth and reduce risk for overweight status in infancy are lacking. To examine the effect of a responsive parenting (RP) intervention on infant weight gain between birth and 28 weeks and overweight status at age 1 year. The Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) study is an ongoing randomized clinical trial comparing an RP intervention designed to prevent childhood obesity with a safety control. The study includes primiparous mother-newborn dyads (n = 291) and was conducted at the Penn State Milton S. Hershey Medical Center, Hershey, Pennsylvania, in addition to home visits. Enrollment was initiated in January 2012, and evaluable population analyses for this study were conducted between April 2015 and November 2015. At 2 weeks post partum, initial intervention materials appropriate to the assigned treatment group were mailed to the participant's home. Research nurses conducted home visits at 3 weeks, 16 weeks, 28 weeks, and 40 weeks, and a research center visit occurred at 1 year. The Intervention Nurses Start Infants Growing on Healthy Trajectories curriculum included messages about infant feeding, sleep hygiene, active social play, emotion regulation, and growth record education. The control group received a developmentally appropriate home safety intervention also delivered by nurse home visitors. Conditional weight gain from birth to 28 weeks was calculated. General linear models examined intervention effect on conditional weight gain. The intervention's effect on infant weight-for-length percentiles was tested using analysis of variance. Logistic regression compared the odds of overweight status (weight for length ≥95th percentile) at 1 year as a function of conditional weight gain. Of the mothers included in the study, 246 were white (88%), 260 were non-Hispanic (93%), 210 were married (75%), and 201 were working full time (72%) at time of enrollment. The mean conditional weight gain score was lower among infants in the RP group compared with the control group (-0.18; 95% CI, -0.36 to -0.001), reflecting that the RP infants gained weight more slowly than control group infants (0.18; 95% CI, 0.02-0.34); this effect did not differ by feeding mode (predominantly fed breast milk or not). Infants in the RP group also had lower mean weight-for-length percentiles at 1 year than infants in the control group (57.5%; 95% CI, 52.56%-62.37% vs 64.4%; 95% CI, 59.94%-69.26%; P = .04) and were less likely to be overweight at age 1 year (5.5% vs 12.7%; P = .05). An RP intervention is associated with reduced rapid weight gain during the first 6 months after birth and overweight status at age 1 year. clinicaltrials.gov Identifier: NCT01167270.

Obesity is a significant cause of functional limitations in older adults; yet, concerns that weight reduction could diminish muscle along with fat mass have impeded progress toward an intervention. Meal-based enhancement of protein intake could protect function and/or lean mass but has not been studied during geriatric obesity reduction. In this 6-month randomized controlled trial, 67 obese (body mass index ≥30kg/m(2)) older (≥60 years) adults with a Short Physical Performance Battery score of 4-10 were randomly assigned to a traditional (Control) weight loss regimen or one with higher protein intake (>30g) at each meal (Protein). All participants were prescribed a hypo-caloric diet, and weighed and provided dietary guidance weekly. Physical function (Short Physical Performance Battery) and lean mass (BOD POD), along with secondary measures, were assessed at 0, 3, and 6 months. At the 6-month endpoint, there was significant (p < .001) weight loss in both the Control (-7.5±6.2kg) and Protein (-8.7±7.4kg) groups. Both groups also improved function but the increase in the Protein (+2.4±1.7 units; p < .001) was greater than in the Control (+0.9±1.7 units; p < .01) group (p = .02). Obese, functionally limited older adults undergoing a 6-month weight loss intervention with a meal-based enhancement of protein quantity and quality lost similar amounts of weight but had greater functional improvements relative to the Control group. If confirmed, this dietary approach could have important implications for improving the functional status of this vulnerable population (ClinicalTrials.gov identifier: NCT01715753). © The Author 2016.

Abstract Background: Obesity is a significant cause of functional limitations in older adults; yet, concerns that weight reduction could diminish muscle along with fat mass have impeded progress toward an intervention. Meal-based enhancement of protein intake could protect function and/or lean mass but has not been studied during geriatric obesity reduction. Methods: In this 6-month randomized controlled trial, 67 obese (body mass index ≥30kg/m2) older (≥60 years) adults with a Short Physical Performance Battery score of 4–10 were randomly assigned to a traditional (Control) weight loss regimen or one with higher protein intake (>30g) at each meal (Protein). All participants were prescribed a hypo-caloric diet, and weighed and provided dietary guidance weekly. Physical function (Short Physical Performance Battery) and lean mass (BOD POD), along with secondary measures, were assessed at 0, 3, and 6 months. Results: At the 6-month endpoint, there was significant (p < .001) weight loss in both the Control (−7.5±6.2kg) and Protein (−8.7±7.4kg) groups. Both groups also improved function but the increase in the Protein (+2.4±1.7 units; p < .001) was greater than in the Control (+0.9±1.7 units; p < .01) group (p = .02). Conclusion: Obese, functionally limited older adults undergoing a 6-month weight loss intervention with a meal-based enhancement of protein quantity and quality lost similar amounts of weight but had greater functional improvements relative to the Control group. If confirmed, this dietary approach could have important implications for improving the functional status of this vulnerable population (ClinicalTrials.gov identifier: NCT01715753). PMID:26786203

In the Neurolab mission, we found that spaceflight affects the development of the aortic baroreflex system and the body weight of the flight rats was significantly lighter [correction of lightess] than that of the control group. The aim of this study is to examine the structural and functional development in various tissues and organs. One hundred and eighteen nine-day old rats and seven fifteen-day old rats, which were launched at these ages and nursed by their dams in the space shuttle Columbia for 16 days, were served for this study. Two hundred and twenty one neonates were used as the ground controls (VIV: vivarium and AGC: asynchronous ground controls). On the landing day after they returned to the earth, the rats were perfused with a fixative under deep urethane anesthesia, and the organs were weighed and the ratio of the organ weight to the body weight was calculated. Six animals of the nine-day old group were reared on the ground for 30 more days after landing and also examined in the same protocol as the landing-day-examination. The organs obtained to examine were heart, lung, spleen, thymus, adrenal glands, kidney, liver, small intestine, large intestine, mesentery, pancreas, testis and ovary. Paraffin sections were made from some organ tissues and prepared for HE staining and immunohistochemistry. We compared these organs in the flight rat with those in the ground controls. All organs except the lung of nine-day old group were significantly smaller. In the ratio of organ weight to body weight, the lung and heart were significantly larger. The weight and ratio of the liver showed no significant difference. The thymus, spleen, mesentery and pancreas were smaller in the weight and the ratio. There were no differences in the body weight among 30-day reared groups, but the lung in the flight group is significantly heavier than the control groups and thymus also tends to be relatively heavy. In flight rats of the fifteen-day group, the kidney was heavy and the ovary was light as compared to the controls. The adipose tissue was macroscopically little found around the thoracic and abdominal organs in all rats of the flight group. These results suggest that the organs related to oxygen supply like as the lung and heart have priority in development over the mesentery and immune system organs even during spaceflight. Lightness of the mesentery in space rats is due to small contents of adipose tissues, and may reflect amounts of the food taken by the flight dams. Lightness of the organs like as the thymus, spleen and pancreas suggests that spaceflight may affect the immune system and also affect continuously the lung and thymus development even after landing.

Effect of periodontal therapy on pregnancy outcome in women affected by periodontitis.

There is convincing evidence to suggest that infections affecting the mother during pregnancy may produce alterations in the normal cytokine- and hormone-regulated gestation, which could result in preterm labor, premature rupture of membranes, and preterm birth (PTB). Studies in the late 1990s associated periodontitis with preterm low birth weight (PLBW) deliveries, and this may have similar pathogenic mechanisms as other maternal infections. This study determined the effect of non-surgical periodontal therapy on pregnancy outcome. A total of 200 pregnant women with periodontitis were randomly assigned to treatment and control groups. Detailed data about previous and current pregnancies were obtained. All women received a full-mouth periodontal examination, including oral hygiene index-simplified, bleeding index, and clinical attachment level. The women in the treatment group received non-surgical periodontal therapy during the gestational period, and those in the control group received periodontal treatment after delivery. Periodontal therapy included plaque control instructions and scaling and root planing performed under local anesthesia. The outcome measures assessed were gestational age and birth weight of the infant. PTB was recorded when delivery occurred at <37 weeks of gestation, and low birth weight (LBW) was recorded when the infant weighed<2,500 g. There were 53 PTBs in the treatment group and 68 PTBs in the control group. Twenty-six LBW infants were recorded in the treatment group, and 48 LBW infants were noted in the control group. The mean gestational ages were 33.8+/-2.8 weeks and 32.7+/-2.8 weeks in the treatment and control groups, respectively. The difference was statistically significant at P<0.006. The mean birth weight was 2,565.3+/-331.2 g in the treatment group and 2,459.6+/-380.7 g in the control group, with the difference being statistically significant at P<0.044. A multiple regression model showed a significant effect of periodontal treatment on birth outcomes. Non-surgical periodontal therapy can reduce the risk for preterm births in mothers who are affected by periodontitis. Additional multicentered, randomized, controlled clinical trials are required to confirm this link between periodontitis and PLBW.

To explore the effects of obstructive sleep apnea syndrome (OSAS) on children's growth by the study of identical twins. Seventeen cases of nonobese children with OSAS were included in this study. The control group was their identical twin sibling, who had no signs of OSAS. Data including height, weight, and serum insulin-like growth factor 1 levels were analyzed before tonsillectomy and adenoidectomy (T&A) and at 3, 6, and 12 months after surgery. The mean apnea hyponea index was 3.9 times/hour in patients with OSAS and became normal after surgery. Minimum oxygen saturation gradually increased after T&A. The height and weight of the OSAS group before T&A was lower than the control group. During the follow-up period, height and weight increased but were lower than the control group. Serum insulin-like growth factor 1 levels in the OSAS group before T&A were lower than the control group. The level was significantly increased 3 months after T&A. OSAS impairs growth and development. Significant growth recovery occurs after T&A, and early surgical intervention is an important factor for improvement in growth. Copyright © 2015.

Obesity is associated with poorly differentiated and advanced prostate cancer and increased mortality. In preclinical models, caloric restriction delays prostate cancer progression and prolongs survival. We sought to determine if weight loss (WL) in men with prostate cancer prior to radical prostatectomy affects tumor apoptosis and proliferation, and if WL effects other metabolic biomarkers. In this Phase II prospective trial, overweight and obese men scheduled for radical prostatectomy were randomized to a 5-8 week WL program consisting of standard structured energy-restricted meal plans (1200-1500 Kcal/day) and physical activity or to a control group. The primary endpoint was apoptotic index in the radical prostatectomy malignant epithelium. Secondary endpoints were proliferation (Ki67) in the radical prostatectomy tissue, body weight, body mass index (BMI), waist to hip ratio, body composition, and serum PSA, insulin, triglyceride, cholesterol, testosterone, estradiol, leptin, adiponectin, interleukin 6, interleukin 8, insulin-like growth factor 1, and IGF binding protein 1. In total 23 patients were randomized to the WL intervention and 21 patients to the control group. Subjects in the intervention group had significantly more weight loss (WL:-3.7 ± 0.5 kg; Control:-1.6 ± 0.5 kg; p = 0.007) than the control group and total fat mass was significantly reduced (WL:-2.1 ± 0.4; Control: 0.1 ± 0.3; p = 0.015). There was no significant difference in apoptotic or proliferation index between the groups. Among the other biomarkers, triglyceride, and insulin levels were significantly decreased in the WL compared with the control group. In summary, this short-term WL program prior to radical prostatectomy resulted in significantly more WL in the intervention vs. the control group and was accompanied by significant reductions in body fat mass, circulating triglycerides, and insulin. However, no significant changes were observed in malignant epithelium apoptosis or proliferation. Future studies should consider a longer term or more intensive weight loss intervention.

Challenging Expected Patterns of Weight Loss in Full-Term Breastfeeding Neonates Born by Cesarean.

Thulier, Diane

To determine the mean weight loss (MWL) of newborns and to examine the effect of weight loss > 7% on exclusive breastfeeding rates. A secondary analysis from a retrospective case-control study of maternal hydration and neonatal weight. A Level III maternity hospital in the Northeast region of the United States. A total of 286 women and their term breastfeeding newborns born by cesarean. Data were collected by chart review from birth through Days 3 or 4. Newborns who lost more than 7% of birth weight by Day 3 were included in the case group, and newborns who lost 7% or less by Day 3 were included in the control group. A significance level of .05 was used for all statistical analysis. Day 3 MWL for all newborns was 8% (n = 286, 7.9% ± 2.2%). MWL for the control group (n = 121) was 6% (5.93% ± 1.31%), and MWL for the case group (n = 165) was over 9% (9.35% ± 1.38%). Predominately breastfed newborns were still losing weight on Day 4 (MWL = 7.58%). Newborns who lost 7% or less had little change in exclusive breastfeeding, from 87% to 80% by Day 4. In contrast, exclusive breastfeeding in newborns who lost more than 7% dropped markedly, from 90% to 53% (p < .001). Weight loss of more than 7% appears to be a normal phenomenon among full-term newborns. When weight loss reached 7%, formula supplementation increased markedly. Predominately breastfed newborns are most at risk for continued weight loss after hospital discharge. Copyright © 2017 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

Choline is an essential nutrient utilized for phosphatidylcholine biosynthesis and lipoprotein packaging and secretion. Recently, choline supplementation has been used by athletes and the public for weight loss. However, the potential toxicological impact of choline dietary supplementation requires further investigation. This study examined the effects of choline dietary supplementation in Sprague Dawley rats for 4 weeks. Rats were fed diets containing basal choline levels (control) or 5-, 10-, or 15-fold (5×, 10×, or 15×) basal diet concentration. In groups fed choline-supplemented diets, there were no toxicologically relevant findings in clinical observations, food intake, clinical chemistry, liver weights, or liver histopathology. However, decreased mean body weights (8.5-10.2%) and body weight gains (24-31%) were noted for the 10× choline-supplemented (females only) and 15× choline-supplemented (both sexes) groups relative to the control groups from day 3 onward. These body weight effects were not related to a persistent reduction in average food intake. Serum cholesterol was increased in the 15× choline-supplemented male rats relative to the controls, an expected effect of choline supplementation; however, there were no changes in the serum cholesterol of female rats. Serum choline concentrations were increased in female rats relative to the male rats across all treatment groups. The maximum tolerated dose for male and female rats were the 15× and 10× choline supplements, respectively, based on decreased mean body weight and body weight gains. This study supported the conclusions of a clinical trial that showed a high choline diet can decrease body weight in humans.

Objective: This study examined the efficacy of a commercially available, portion-controlled diet (PCD) on body weight and HbA1c over 6 months in obese patients with type 2 diabetes. Research Design and Methods: One-hundred participants with a mean±s.d. age of 55.6±10.6 year, body weight of 102.9±18.4 kg and HbA1c of 7.7±1.3% were randomly assigned to a 9-session group lifestyle intervention that included a PCD or to a 9-session group program of diabetes self-management education (DSME). Participants in the two groups were prescribed the same goals for energy intake (1250–1550 kcal per day) and physical activity (200 min per week). Results: While both groups produced significant improvements in weight and HbA1c after 6 months of treatment, PCD participants lost 7.3 kg [95% confidence interval (CI): −5.8 to −8.8 kg], compared with 2.2 kg (95% CI: −0.7 to −3.7 kg) in the DSME group (P<0.0001). Significantly more PCD than DSME participants lost ⩾5% of initial weight (54.0% vs 14.0%, P<0.0001) and ⩾10% (26.0% vs 6.0%, P<0.0001). HbA1c declined by 0.7% (95% CI: −0.4 to −1.0%) in the PCD group, compared with 0.4% (95% CI: −0.1 to −0.7%) in DSME (P<0.026). Across both groups, larger weight losses were associated with greater reductions in HbA1c (r=0.52, P<0.0001). Conclusions: These findings demonstrate that a commercially available portion-controlled meal plan can induce clinically meaningful improvements in weight and glycemic control in obese individuals with type 2 diabetes. These data have implications for the management of obesity in primary care, as now provided by the Centers for Medicare and Medicaid Services. PMID:23507967

To compare the effect of Kangaroo mother care (KMC) and conventional methods of care (CMC) on growth in LBW babies (> 2000 g). Randomized controlled trial. Level III NICU of a teaching institution in western India. 206 neonates with birth weight < 2000 g. The subjects were randomized into two groups: the intervention group (KMC-103) received Kangaroo mother care. The control group (CMC: 103) received conventional care. Growth, as measured by average daily weight gain and by other anthropometrical parameters at 40 weeks postmenstrual age in preterm babies and at 2500 g in term SGA infants was assessed. The KMC babies had better average weight gain per day (KMC: 23.99 g vs CMC: 15.58 g, P< 0.0001). The weekly increments in head circumference (KMC: 0.75 cm vs CMC: 0.49 cm, P = 0.02) and length (KMC: 0.99 cm vs CMC: 0.7 cm, P = 0.008) were higher in the KMC group. A significantly higher number of babies in the CMC group suffered from hypothermia, hypoglycemia, and sepsis. There was no effect on time to discharge. More KMC babies were exclusively breastfed at the end of the study (98% vs 76%). KMC was acceptable to most mothers and families at home. Kangaroo mother care improves growth and reduces morbidities in low birth weight infants. It is simple, acceptable to mothers and can be continued at home.

To test the feasibility and effectiveness of a Web-based lifestyle intervention based on the Diabetes Prevention Program modified for women with recent gestational diabetes mellitus to reduce postpartum weight retention. We randomly allocated 75 women with recent gestational diabetes mellitus to either a Web-based lifestyle program (Balance after Baby) delivered over the first postpartum year or to a control group. Primary outcomes were change in body weight at 12 months from 1) first postpartum measured weight; and 2) self-reported prepregnancy weight. There were no significant differences in baseline characteristics between groups including age, body mass index, race, and income status. Women assigned to the Balance after Baby program (n=36, three lost to follow-up) lost a mean of 2.8 kg (95% confidence interval -4.8 to -0.7) from 6 weeks to 12 months postpartum, whereas the control group (n=39, one lost to follow-up) gained a mean of 0.5 kg (-1.4 to +2.4) (P=.022). Women in the intervention were closer to prepregnancy weight at 12 months postpartum (mean change -0.7 kg; -3.5 to +2.2) compared with women in the control arm (+4.0 kg; +1.3 to +6.8) (P=.035). A Web-based lifestyle modification program for women with recent gestational diabetes mellitus decreased postpartum weight retention. ClinicalTrials.gov, www.clinicaltrials.gov, NCT01158131. I.

Extended contact interventions provide support for continued weight management (weight loss/prevention of weight regain) following a weight loss intervention. Text messages offer a medium for delivery in a potentially cost-effective, broad-reach manner. This study aims to examine (i) the effectiveness of extended contact, text message interventions for adults in supporting weight management, and (ii) which intervention characteristics are common to those that are effective. A systematic database search (to 19 September 2016) was conducted. Meta-analyses were performed to quantify the average weight changes (kg) during the extended contact intervention, net of control (if a control group was present) and within-group. Seven studies were eligible for inclusion. The pooled effect of the extended contact intervention compared with control (n = 3 studies) was -0.82 kg (95% confidence interval -1.43, -0.21), while the pooled within-group weight loss (n = 6 studies) during the extended contact interventions was -2.16 kg (95% confidence interval -3.40, -0.91). Interventions considered 'effective' (n = 4) were more likely to be >12 weeks duration, compared with interventions considered 'ineffective' (n = 3). Evidence from the small number of studies reviewed suggests that extended contact, text message-delivered interventions are effective. Further research is required to elucidate effective intervention components and the longer-term impact on weight, diet and physical activity behaviour. © 2017 World Obesity Federation.

Nestling European starlings (Sturnus vulgaris), raised and fed by free-living adults, were given daily oral doses of either distilled water, 193 mg sodium as Na2CO3 per kg of body weight (sodium control group), or 6, 10, 13, 17,23, 30, 40, 80, 160 mg of the fluoride ion as NaF in distilled water per kg of body weight (mg/kg). Dosing began when nestlings were 24-48 hr old and continued for 16 days. The 24-hr LD50 of fluoride for day-old starlings was 50 mg/kg. The 16-day LD50 was 17 mg/kg. The sodium control group did not differ from the water control group with respect to any of the measured variables. Growth rates were significantly reduced in the 13 and 17 mg of fluoride/kg groups; weights of birds given higher dose levels were omitted from growth comparisons because of high, fluoride-induced mortality. Although pre-fledging weights for the 10, 13, and 17 mg of fluoride/kg groups averaged 3.6 to 8.6% less than controls at 17 days, this difference was not significant. Feather and bone growth of the fluoride and control groups were not different, except for keel length measured at 17 days of age which averaged less in the fluoride groups. Liver and spleen weights were not affected by fluoride treatments. No histological damage related to fluoride treatments was found in liver, spleen, or kidney. The logarithm of bone fluoride and magnesium concentration increased with the logarithm of increasing fluoride treatment levels and were significantly correlated with each other. Fluoride treatments had no effect on percent calcium or phosphorus in bone or plasma alkaline phosphatase activity. Oral doses of fluoride appear to be more toxic than equivalent dietary levels. Most birds probably acquire fluoride through their diet. Therefore, the results of the study may overestimate the potential effects of fluorides on songbirds living in fluoride-contaminated environments.

Although the benefits of in-person Diabetes Prevention Program (DPP) classes for diabetes prevention have been demonstrated in trials, effectiveness in clinical practice is limited by low participation rates. This study explores whether text message support enhances weight loss in patients offered DPP classes. English- and Spanish-speaking patients with prediabetes (n = 163) were randomized to the control group, which only received an invitation to DPP classes as defined by the Centers for Disease Control and Prevention, or to the text message-augmented intervention group, which also received text messages adapted from the DPP curriculum for 12 months. Mean weight decreased 0.6 pounds (95% CI -2.7 to 1.6) in the control group and 2.6 pounds (95% CI -5.5 to 0.2) in the intervention group (P value 0.05). Three percent weight loss was achieved by 21.5% of participants in the control group (95% CI 12.5-30.6), compared with 38.5% in the intervention group (95% CI 27.7-49.3) (absolute difference 17.0%; P value 0.02). Mean glycated hemoglobin (HbA1c) increased by 0.19% or 2.1 mmol/mol (95% CI -0.1 to 0.5%) and decreased by 0.09% or 1.0 mmol/mol (95% CI -0.2 to 0.0%) in the control group and intervention participants, respectively (absolute difference 0.28%; P value 0.07). Stratification by language demonstrated a significant treatment effect in Spanish speakers but not in English speakers. Text message support can lead to clinically significant weight loss in patients with prediabetes. Further study assessing effect by primary language and in an operational setting is warranted. © 2016 by the American Diabetes Association.

Objective To compare results of obese patients with knee osteoarthritis (OA) who, after an intensive weight loss regimen, received 1 year of either dietary support (D), a knee-exercise program (E), or “no attention” (C; control group). Methods We conducted a randomized, 2-phase, parallel-group trial. A total of 192 obese participants with knee OA were enrolled; the mean age was 62.5 years and 81% were women with a mean entry weight of 103.2 kg. In phase 1, all participants were randomly assigned to 1 of 3 groups and began a dietary regimen of 400–810 and 1,250 kcal/day for 16 weeks (2 8-week phases) to achieve a major weight loss. Phase 2 consisted of 52 weeks' maintenance in either group D, E, or C. Outcomes were changes from randomization in pain on a 100-mm visual analog scale, weight, and response according to the Outcome Measures in Rheumatology-Osteoarthritis Research Society International criteria. Results Mean weight loss for phase 1 was 12.8 kg. After 1 year on maintenance therapy, the D group sustained a lower weight (11.0 kg, 95% confidence interval [95% CI] 9.0, 12.8 kg) than those in the E (6.2, 95% CI 4.4, 8.1 kg) and C (8.2, 95% CI 6.4, 10.1 kg) groups (P = 0.002 by analysis of covariance [ANCOVA]). Adherence was low in the E group. All groups had statistically significant pain reduction (D: 6.1; E: 5.6; and C: 5.5 mm) with no difference between groups (P = 0.98 by ANCOVA). In each group 32 (50%), 26 (41%), and 33 (52%) participants responded to treatment in the D, E, and C groups, respectively, with no statistically significant difference in the number of responders (P = 0.41). Conclusion A significant weight reduction with a 1-year maintenance program improves knee OA symptoms irrespective of maintenance program. PMID:25370359

To evaluate the beneficial effects of green plantain-based diet on stool volume, frequency and weight gain as compared with a traditional yogurt-based diet in children with persistent diarrhea. In a prospective, in-hospital controlled trial, two different treatments were administered to a sample of 80 children of both sexes, with ages ranging from 1 to 28 months, who had experienced >or= 14 days of persistent diarrhea. The sample was divided into two groups of isocaloric (100 kcal/kg/d) diets: experimental and control, of 40 patients each. The experimental group was randomly given a-week treatment consisting of a 50 g/L of cooked green plantain-based diet. The control group was fed on a yogurt-based diet. Both groups were not statistically different at admission. Pathogens were isolated from stools in 21.2% and 25% of patients in the experimental and control groups respectively; Aeromonas hydrophilia and Shigela flexneri were the most frequently found bacteria. The experimental group fed on a green plantain diet had a significantly better response in: diminishing stool output and consistency (p < 0.002), stool weight, diarrhea duration (p < 0.001), and increasing daily body weight gain (p < 0.001) than the yogurt-based diet group. The average duration of diarrhea in the plantain-based diet group was 18 hours shorter (p < 0.005) and it also had lower cost (p < 0.005). Our results support the benefits of green plantain in the dietary management of persistent diarrhea in hospitalized children, in relation to diarrheal duration, weight gain and costs.

Introduction Obesity is a health disorder and increasing all over the world. It is also a cause for many non-communicable diseases. Yoga practice reduces the stress level which may improve the eating habits and help in weight reduction. Aim To assess the final outcome of the effects after 3 months of the 14 weeks yoga training on obesity of adult male in an urban setting. Materials and Methods This was a randomized controlled trial with parallel groups (Yoga and Control groups) on male obese. Total 80 subjects with Body Mass Index (BMI) between 25 to 35 kg/cm2 were enrolled and randomized into two equal groups in which 72 subjects (yoga n = 37 and control n=35) completed the trial. Yoga group mean age ± SD was 40.03±8.74 and Control group mean age±SD was 42.20±12.06. A 14 weeks special IAYT (Integrated Approach of Yoga Therapy) yoga training was given to the Yoga group and no specific activity was given to Control group. The interim results of this study at 14 weeks were covered in another article which is under process. After the 14 weeks of yoga training the Yoga group was asked to continue the yoga practice for the next 3 months and the Control group was not given any physical activity. The final outcome is covered in this paper. The assessments were anthropometric parameters of body weight (Wt), BMI (Body Mass Index), MAC (Mid-upper Arm Circumferences of left and right arm), WC (Waist Circumference), HC (Hip Circumference), WHR (Waist Hip Ratio), SKF (Skin Fold Thickness) of biceps, triceps, sub scapular, suprailiac and cumulative skin fold thickness value), Percentage body fat based on SKF and Psychological questionnaires of PSS (Perceived Stress Scale) and AAQW (Acceptance and Action Questionnaire for Weight related difficulty). Assessments were taken after 3 months of yoga training, for both Yoga and Control groups. Within group, between group and correlation analyses were carried out using SPSS 21. Results Improvement in anthropometric and psychological parameters such as Wt, Percentage body fat, PSS were observed in the final outcome. Also, some of the improvements such as AAQW score were lost in the final outcome, compared to interim results. Conclusion The yoga practice is effective for obesity control for adult male in an urban setting. PMID:28050422

This is a retrospective study to investigate whether motivational interviewing increases weight loss among obese or overweight women prior to fertility treatment. Women with body mass index (BMI) > 30 kg/m(2) approaching the Fertility Clinic, Regional Hospital Skive, were given advice about diet and physical activity with the purpose of weight loss. In addition, they were asked if they wanted to receive motivational interviewing. Among other data, age, height and weight were obtained. Main outcomes were weight loss measured in kg and decrease in BMI. We studied 187 women: 110 received sessions of motivational interviewing (intervention group, n = 110), 64 received motivational support by phone or e-mail only and 13 women did not wish any motivational support (control group, n = 77). The mean weight loss and decrease in BMI was greater in the intervention group compared with the control group (9.3 kg versus 7.3 kg, difference p = 0.01, 3.3 kg/m(2) versus 2.6 kg/m(2), difference p = 0.02). The mean period of intervention was comparable in the two groups, 7.9 month and 7.3 month, respectively, (difference non significant: NS). The study indicates that motivational interviewing may be a valuable tool in weight loss programs for obese and overweight women prior to fertility treatment.

OBJECTIVE To compare the effects of a 1-year intervention with a low-carbohydrate and a low-fat diet on weight loss and glycemic control in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS This study is a randomized clinical trial of 105 overweight adults with type 2 diabetes. Primary outcomes were weight and A1C. Secondary outcomes included blood pressure and lipids. Outcome measures were obtained at 3, 6, and 12 months. RESULTS The greatest reduction in weight and A1C occurred within the first 3 months. Weight loss occurred faster in the low-carbohydrate group than in the low-fat group (P = 0.005), but at 1 year a similar 3.4% weight reduction was seen in both dietary groups. There was no significant change in A1C in either group at 1 year. There was no change in blood pressure, but a greater increase in HDL was observed in the low-carbohydrate group (P = 0.002). CONCLUSIONS Among patients with type 2 diabetes, after 1 year a low-carbohydrate diet had effects on weight and A1C similar to those seen with a low-fat diet. There was no significant effect on blood pressure, but the low-carbohydrate diet produced a greater increase in HDL cholesterol. PMID:19366978

The aim of the present study was to investigate the protective role of Ginkgo biloba L. leaf extract against the active agent of Roundup® herbicide (Monsanto, Creve Coeur, MO, USA). The Swiss Albino mice were randomly divided into six groups, with each group consisting of six animals: Group I (control) received an intraperitoneal injection of dimethyl sulfoxide (0.2 mL, once only), Group II received glyphosate at a dose of 50 mg/kg of body weight, Group III received G. biloba at a dose of 50 mg/kg of body weight, Group IV received G. biloba at a dose of 150 mg/kg of body weight, Group V received G. biloba (50 mg/kg of body weight) and glyphosate (50 mg/kg of body weight), and Group VI received G. biloba (150 mg/kg of body weight) and glyphosate (50 mg/kg of body weight). The single dose of glyphosate was given intraperitoneally. Animals from all the groups were sacrificed at the end of 72 hours, and their blood, bone marrow, and liver and kidney tissues were analyzed for aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), creatinine, malondialdehyde (MDA), and glutathione (GSH) levels and the presence of micronucleus (MN), chromosomal aberrations (CAs), and pathological damages. The results indicated that serum AST, ALT, BUN, and creatinine levels significantly increased in mice treated with glyphosate alone compared with the other groups (P<.05). Besides, glyphosate-induced oxidative damage caused a significant decrease in GSH levels and a significant increase in MDA levels of the liver and kidney tissues. Moreover, glyphosate alone-treated mice presented higher frequencies of CAs, MNs, and abnormal metaphases compared with the controls (P<.05). These mice also displayed a lower mean mitotic index than the controls (P<.05). Treatment with G. biloba produced amelioration in indices of hepatotoxicity, nephrotoxicity, lipid peroxidation, and genotoxicity relative to Group II. Each dose of G. biloba provided significant protection against glyphosate-induced toxicity, and the strongest effect was observed at a dose of 150 mg/kg of body weight. Thus, in vivo results showed that G. biloba extract is a potent protector against glyphosate-induced toxicity, and its protective role is dose-dependent.

Family variables such as cohesion and nurturance have been associated with adolescent weight-related health behaviors. Integrating family variables that improve family functioning into traditional weight-loss programs can provide health-related benefits. The current study evaluated a family-based psychoeducational and behavioral skill-building weight-loss program for adolescent girls that integrated Family Systems and Social Cognitive Theories. Forty-two overweight (> or = 95th percentile) female adolescent participants and parents participated in a 16-week randomized controlled trial comparing three groups: multifamily therapy plus psychoeducation (n=15), psychoeducation-only (n=16), or wait list (control; n=11) group. Body mass index, energy intake, and family measures were assessed at baseline and posttreatment. Adolescents in the psychoeducation-only group demonstrated a greater decrease in energy intake compared to the multifamily therapy plus psychoeducation and control groups (P<0.01). Positive changes in family nurturance were associated with lower levels of adolescent energy intake (P<0.05). No significant effects were found for body mass index. Results provide preliminary support for a psychoeducational program that integrates family variables to reduce energy intake in overweight adolescent girls. Results indicate that nurturance can be an important family variable to target in future adolescent weight-loss and dietary programs.

Self-monitoring is a cornerstone of behavioral lifestyle interventions for obesity and type 2 diabetes mellitus. Mobile technology has the potential to improve adherence to self-monitoring and patient outcomes. However, no study has tested the use of a smartphone to facilitate self-monitoring in overweight or obese adults with type 2 diabetes mellitus living in the underserved community. The aim of this study was to examine the feasibility of and compare preliminary efficacy of a behavioral lifestyle intervention using smartphone- or paper-based self-monitoring of multiple behaviors on weight loss and glycemic control in a sample of overweight or obese adults with type 2 diabetes mellitus living in underserved communities. We conducted a randomized controlled trial to examine the feasibility and preliminary efficacy of a behavioral lifestyle intervention. Overweight or obese patients with type 2 diabetes mellitus were recruited from an underserved minority community health center in Houston, Texas. They were randomly assigned to one of the three groups: (1) behavior intervention with smartphone-based self-monitoring, (2) behavior intervention with paper diary-based self-monitoring, and (3) usual care group. Both the mobile and paper groups received a total of 11 face-to-face group sessions in a 6-month intervention. The mobile group received an Android-based smartphone with 2 apps loaded to help them record their diet, physical activity, weight, and blood glucose, along with a connected glucometer, whereas the paper group used paper diaries for these recordings. Primary outcomes of the study included percentage weight loss and glycated hemoglobin (HbA 1c ) changes over 6 months. A total of 26 patients were enrolled: 11 in the mobile group, 9 in the paper group, and 6 in the control group. We had 92% (24/26) retention rate at 6 months. The sample is predominantly African Americans with an average age of 56.4 years and body mass index of 38.1. Participants lost an average of 2.73% (mobile group) and 0.13% (paper group) weight at 6 months, whereas the control group had an average 0.49% weight gain. Their HbA 1c changed from 8% to 7 % in mobile group, 10% to 9% in paper group, and maintained at 9% for the control group. We found a significant difference on HbA 1c at 6 months among the 3 groups (P=.01). We did not find statistical group significance on percentage weight loss (P=.20) and HbA 1c changes (P=.44) overtime; however, we found a large effect size of 0.40 for weight loss and a medium effect size of 0.28 for glycemic control. Delivering a simplified behavioral lifestyle intervention using mobile health-based self-monitoring in an underserved community is feasible and acceptable and shows higher preliminary efficacy, as compared with paper-based self-monitoring. A full-scale randomized controlled trial is needed to confirm the findings in this pilot study.

The mobile group received an Android-based smartphone with 2 apps loaded to help them record their diet, physical activity, weight, and blood glucose, along with a connected glucometer, whereas the paper group used paper diaries for these recordings. Primary outcomes of the study included percentage weight loss and glycated hemoglobin (HbA1c) changes over 6 months. Results A total of 26 patients were enrolled: 11 in the mobile group, 9 in the paper group, and 6 in the control group. We had 92% (24/26) retention rate at 6 months. The sample is predominantly African Americans with an average age of 56.4 years and body mass index of 38.1. Participants lost an average of 2.73% (mobile group) and 0.13% (paper group) weight at 6 months, whereas the control group had an average 0.49% weight gain. Their HbA1c changed from 8% to 7 % in mobile group, 10% to 9% in paper group, and maintained at 9% for the control group. We found a significant difference on HbA1c at 6 months among the 3 groups (P=.01). We did not find statistical group significance on percentage weight loss (P=.20) and HbA1c changes (P=.44) overtime; however, we found a large effect size of 0.40 for weight loss and a medium effect size of 0.28 for glycemic control. Conclusions Delivering a simplified behavioral lifestyle intervention using mobile health–based self-monitoring in an underserved community is feasible and acceptable and shows higher preliminary efficacy, as compared with paper-based self-monitoring. A full-scale randomized controlled trial is needed to confirm the findings in this pilot study.

NTP Toxicology and Carcinogenesis Studies of Nitromethane (CAS No. 75-52-5) in F344/N Rats and B6C3F1 Mice (Inhalation Studies).

PubMed

1997-02-01

Nitromethane is used as a rocket and engine fuel; as a synthesis intermediate for agricultural fumigants, biocides, and other products; as a solvent; and as an explosive in mining, oil-well drilling, and seismic exploration. It has been detected in air, in surface and drinking water, and in cigarette smoke. Nitromethane was studied because of the potential for widespread human exposure and because it is structurally related to the carcinogens 2-nitropropane and tetranitromethane. Male and female F344/N rats and B6C3F1 mice received nitromethane (purity 98% or greater) by inhalation for 16 days, 13 weeks, or 2 years. Genetic toxicology studies were conducted in Salmonella typhimurium, cultured Chinese hamster ovary cells, and peripheral blood erythrocytes of mice. 16-DAY STUDY IN RATS: Groups of five male and five female rats were exposed to 0, 94, 188, 375, 750, or 1,500 ppm nitromethane by inhalation, 6 hours per day, 5 days per week, for 16 days. All rats survived until the end of the study. The mean body weight gain of male rats in the 1,500 ppm group was slightly but significantly less than that of the controls; the final mean body weights and mean body weight gains of exposed females were similar to those of the controls. Clinical findings in all male and female rats in the 1,500 ppm groups included increased preening, rapid breathing, hyperactivity early in the study, and hypoactivity and loss of coordination in the hindlimbs near the end of the study. The relative liver weights of all exposed groups of male rats and the absolute and relative liver weights of females exposed to 375 ppm or greater were significantly greater than those of the controls. Minimal to mild degeneration of the olfactory epithelium was observed in the nose of males and females exposed to 375 ppm or greater. Sciatic nerve degeneration was present in all male and female rats exposed to 375 ppm or greater; rats exposed to 750 or 1,500 ppm also had reduced myelin around sciatic axons. 16-DAY STUDY IN MICE: Groups of five male and five female mice were exposed to 0, 94, 188, 375, 750, or 1,500 ppm nitromethane by inhalation, 6 hours per day, 5 days per week, for 16 days. All mice survived to the end of the study. The final mean body weights and weight gains of exposed males and females were similar to those of the controls. Clinical findings included hypoactivity and tachypnea in male and female mice in the 1,500 ppm groups. Absolute and relative liver weights of male mice in the 750 and 1,500 ppm groups and female mice in all exposed groups and the relative liver weight of males in the 375 ppm group were significantly greater than those of the controls. Degeneration of the olfactory epithelium of the nose was observed microscopically in all males and females exposed to 375 ppm or greater; this lesion was of minimal severity in males and minimal to mild severity in females. 13-WEEK STUDY IN RATS: Groups of 10 male and 10 female rats were exposed to 0, 94, 188, 375, 750, or 1,500 ppm nitromethane by inhalation, 6 hours per day, 5 days per week, for 13 weeks. All rats survived to the end of the study. The final mean body weight and weight gain of male rats in the 1,500 ppm group were significantly less than those of the controls. Clinical findings included hindlimb paralysis in rats in the 750 and 1,500 ppm groups. Inhalation exposure of rats to nitromethane resulted in an exposure concentration-dependent, microcytic, responsive anemia; anemia was most pronounced in males and females exposed to 375 ppm or greater. The presence of schistocytes, Heinz bodies, and spherocytes and increased mean cell hemoglobin concentration and methemoglobin concentration were evidence that a hemolytic process was occurring; this hemolytic process could have accounted, in part, for the anemia. Thrombocytosis accompanied the anemia and would be consistent with a reactive bone marrow or could have been due to the erroneous inclusion of small erythrocyte fragments as part of the platelet count. On day 23, transient decreases in serum triiodothyronine, thyroxine, and fr and free thyroxine were observed in male rats exposed to 375 ppm or greater and female rats exposed to 750 or 1,500 ppm. There was little or no pituitary response to the thyroid hormone decreases, as evidenced by the lack of significantly increased concentrations of thyroid-stimulating hormone in exposed rats. No biologically significant differences in organ weights were observed. The forelimb and hindlimb grip strengths of males in the 1,500 ppm group were significantly less than those of the controls. The hindlimb grip strengths of females in the 750 and 1,500 ppm groups were also significantly less than the control value. Minimal to mild hyperplasia of the bone marrow was observed microscopically in male rats in the 750 and 1,500 ppm groups and in females exposed to 188 ppm or greater. Nasal lesions in exposed males and females included olfactory epithelial degeneration in males and females exposed to 375 ppm or greater and in one female exposed to 188 ppm and respiratory epithelial hyaline droplets and goblet cell hyperplasia in males and females in the 750 and 1,500 ppm groups; the severity of nasal lesions in males and females was minimal to mild. Males and females exposed to 375 ppm or greater had minimal to mild degeneration of the sciatic nerve and the lumbar spinal cord. 13-WEEK STUDY IN MICE: Groups of 10 male and 10 female mice were exposed to 0, 94, 188, 375, 750, or 1,500 ppm nitromethane by inhalation, 6 hours per day, 5 days per week, for 13 weeks. All mice survived to the end of the study. The final mean body weights and weight gains of exposed mice were generally similar to those of the controls. There were no treatment-related clinical findings. The absolute right kidney weights of all groups of exposed male mice except the 1,500 ppm group and of females exposed to 188 ppm or greater and the relative right kidney weights of all groups of exposed males and of females in the 750 and 1,500 ppm groups were significantly greater than those of the controls. The absolute liver weight of male mice in the 750 ppm group and the relative liver weights of males exposed to 375 ppm or greater were significantly greater than those of the controls. Olfactory epithelial degeneration and respiratory epithelial hyaline droplets were observed microscopically in all male and female mice exposed to 375 ppm or greater. Degeneration also occurred in females in the 188 ppm group, and hyaline droplets occurred in females in the 94 and 188 ppm groups. The average severity of the nasal lesions ranged from minimal to mild in males. In females, the average severity of olfactory epithelial degeneration ranged from minimal to mild and the severity of respiratory epithelial hyaline droplets ranged from minimal to moderate. All males and nine females in the 1,500 ppm groups also had minimal extramedullary hematopoiesis of the spleen. 2-YEAR STUDY IN RATS: Groups of 50 male and 50 female rats were exposed to 0, 94, 188, or 375 ppm nitromethane by inhalation, 6 hours per day, 5 days per week, for 103 weeks. Survival,Body Weights, and Clinical Findings: There were no significant differences in survival rates between exposed and control male or female rats. The mean body weight of females in the 375 ppm group was slightly greater than that of the control group; the mean body weights of exposed males were generally similar to the mean body weight of the controls throughout the study. Clinical findings were consistent with incidences of mammary gland neoplasms in females exposed to 188 or 375 ppm; no hindlimb paralysis, as occurred in rats in the 13-week study, was observed in male or female rats in the 2-year study. Pathology Findings: The incidences of mammary gland fibroadenoma and fibroadenoma, adenoma, or carcinoma (combined) in female rats in the 188 and 375 ppm groups were significantly greater than those in the controls. Additionally, the incidences of mammary gland carcinoma in the 375 ppm group were significantly greater than those in the controls. 2-YEAR STUDY IN MICE: Groups of 50 male and 50 female mice were exposed to 0, 188, 375, or 750 ppm nitromethane by inhalation, 6 hours per day, 5 days per week, for 103 weeks. Survival,Body Weights, and ClinicalFindings The survival rate of females in the 750 ppm group was marginally greater than that of the controls. The mean body weights of exposed females were generally slightly greater than the mean body weights of the controls during the study but were generally similar to the mean body weight of the controls at the end of the study. The mean body weights of exposed males were similar to those of the controls throughout the study. Clinical findings included swelling around the eyes and exophthalmos in exposed males and females; these findings were coincident with harderian gland neoplasms. Pathology Findings: The incidences of harderian gland adenoma and adenoma or carcinoma (combined) in exposed mice increased with increasing exposure concentration and were significantly greater in males and females in the 375 and 750 ppm groups than those in the controls. The incidences of harderian gland carcinoma in males and females in the 375 and 750 ppm groups were also slightly greater than those in the controls. Female mice in the 188 and 750 ppm groups had significantly greater incidences of hepatocellular adenoma and hepatocellular adenoma or carcinoma (combined) than the controls. The incidences of liver eosinophilic focus increased with increasing exposure concentration, and the incidences in the 375 and 750 ppm groups were significantly greater than the control incidence. The incidences of alveolar/bronchiolar carcinoma in male mice in the 750 ppm group and female mice in the 375 ppm group were significantly greater than those in the controls. Females in the 750 ppm group also had a significantly greater incidence of alveolar/bronchiolar adenoma or carcinoma (combined) and a slightly greater incidence of alveolar/bronchiolar adenoma than the controls. Females in the 375 ppm group had a significantly greater incidence of cellular infiltration of histiocytes in the lung than the controls. The incidences of degeneration and metaplasia of the olfactory epithelium and hyaline degeneration of the respiratory epithelium were significantly greater in exposed male and female mice than those in the controls. Additionally, males in the 375 and 750 ppm groups had significantly greater incidences of inflammation of the nasolacrimal duct than did the controls. GENETIC TOXICOLOGY: Nitromethane was not mutagenic in any tests performed by the NTP. It did not induce mutations in Salmonella typhimurium, with or without S9 metabolic activation, and no induction of sister chromatid exchanges or chromosomal aberrations in cultured Chinese hamster ovary cells exposed to nitromethane was noted with or without S9. No increase in the frequency of micronucleated erythrocytes was observed in peripheral blood samples of male and female mice at the end of the 13-week inhalation study of nitromethane. CONCLUSIONS: Under the conditions of these 2-year inhalation studies, there was no evidence of carcinogenic activity of nitromethane in male F344/N rats exposed to 94, 188, or 375 ppm. There was clear evidence of carcinogenic activity of nitromethane in female F344/N rats based on increased incidences of mammary gland fibroadenomas and carcinomas. There was clear evidence of carcinogenic activity of nitromethane in male B6C3F1 mice based on increased incidences of harderian gland adenomas and carcinomas. There was clear evidence of carcin ogenic activity in female B6C3F1 mice, based on increased incidences of liver neoplasms (primarily adenomas) and harderian gland adenomas and carcinomas. Increased incidences of alveolar/bronchiolar adenomas and carcinomas in male and female mice exposed to nitromethane were also considered to be related to chemical administration. Exposure to nitromethane by inhalation for 2 years resulted in increased incidences of nasal lesions including degeneration and metaplasia of the olfactory epithelium and degeneration of the respiratory epithelium in male and female mice.

We sought to determine whether a behavioral weight reduction intervention would improve nonurinary incontinence lower urinary tract storage symptoms at 6 months, including urinary frequency, nocturia and urgency, compared to a structured education program serving as the control group among overweight and obese women with urinary incontinence. PRIDE (Program to Reduce Incontinence by Diet and Exercise) was a randomized clinical trial performed in 338 overweight or obese women with urinary incontinence. Participants were randomized, including 226 to 6-month behavioral weight loss intervention and 112 to the control group. All participants received a self-help behavioral treatment booklet to improve bladder control. On this secondary data analysis we examined changes in nonurinary incontinence lower urinary tract storage symptoms from baseline to 6 months and the impact of treatment allocation (intervention vs control), weight loss and physical activity. Nonurinary incontinence lower urinary tract storage symptoms were common at baseline, varying from 48% to 62%. In the 2 groups combined women experienced significant improvement in nocturia, urgency and International Prostate Symptom Score at 6 months (all p <0.001). However, lower urinary tract storage symptom outcomes at 6 months did not differ between the intervention and control groups. Similarly no difference was observed in the amount of weight lost (5% or greater vs less than 5%) or physical activity (1,500 kcal or greater expenditure per week compared to less than 1,500 kcal). Lower urinary tract storage symptoms were common among overweight and obese women with urinary incontinence. The prevalence decreased significantly after 6 months independent of treatment group assignment, amount of weight lost or physical activity. These improvements may have been due to self-help behavioral educational materials, trial participation or repeat assessment of symptoms.

Long-term behavioral self-regulation is the hallmark of successful weight control. We tested mediators of weight loss and weight loss maintenance in middle-aged women who participated in a randomized controlled 12-month weight management intervention. Overweight and obese women (N = 225, BMI = 31.3 +/- 4.1 kg/m(2)) were randomly assigned to a control or a 1-year group intervention designed to promote autonomous self-regulation of body weight. Key exercise, eating behavior, and body image variables were assessed before and after the program, and tested as mediators of weight loss (12 months, 86% retention) and weight loss maintenance (24 months, 81% retention). Multiple mediation was employed and an intention-to-treat analysis conducted. Treatment effects were observed for all putative mediators (Effect size: 0.32-0.79, P < 0.01 vs. controls). Weight change was -7.3 +/- 5.9% (12-month) and -5.5 +/- 5.0% (24-month) in the intervention group and -1.7 +/- 5.0% and -2.2 +/- 7.5% in controls. Change in most psychosocial variables was associated with 12-month weight change, but only flexible cognitive restraint (P < 0.01), disinhibition (P < 0.05), exercise self-efficacy (P < 0.001), exercise intrinsic motivation (P < 0.01), and body dissatisfaction (P < 0.05) predicted 24-month weight change. Lower emotional eating, increased flexible cognitive restraint, and fewer exercise barriers mediated 12-month weight loss (R(2) = 0.31, P < 0.001; effect ratio: 0.37), but only flexible restraint and exercise self-efficacy mediated 24-month weight loss (R(2) = 0.17, P < 0.001; effect ratio: 0.89). This is the first study to evaluate self-regulation mediators of weight loss and 2-year weight loss maintenance, in a large sample of overweight women. Results show that lowering emotional eating and adopting a flexible dietary restraint pattern are critical for sustained weight loss. For long-term success, interventions must also be effective in promoting exercise intrinsic motivation and self-efficacy.

Motor skills have previously not been reported in young adults born with very low birth weight (VLBW), although they are commonly reported in children and adolescents. To compare fine and gross motor skills in VLBW young adults with matched term-born controls, and to study longitudinal changes in the VLBW group. A geographically based follow-up study of a VLBW group and a control group. Thirty-six VLBW (birth weight ≤ 1500 g) young adults, including four participants with cerebral palsy (CP), and 37 matched controls (birth weight ≥ 10th centile) were examined at 14 and 23 years of age. Fine and gross motor skills were assessed using Grooved Pegboard test (GP), Trail Making Test-5 (TMT-5), Movement Assessment Battery for Children-2 (Movement ABC-2) and High-level Mobility Assessment Tool (HiMAT). VLBW young adults were slower than controls on GP (p = 0.026) and TMT-5 (p < 0.001). Mean total Movement ABC-2 score was 69.7 ± 20.2 in the VLBW group compared with 74.1 ± 14.4 in the control group (p = 0.017). Differences were also seen in manual dexterity and balance. Additionally, HiMAT showed reduced balance and speed in gross motor skills in the VLBW group. The proportion of participants with motor problems did not change between age 14 and 23. After exclusion of participants with CP, scores were essentially the same. VLBW young adults had overall poorer fine and gross motor skills compared with controls. Reduced speed seemed to be an underlying problem. Longitudinal findings indicate that VLBW children have not outgrown their motor problems when entering adulthood. Copyright © 2013 Elsevier Ltd.

Coriandrum sativum L. (CS) seeds are known to possess therapeutic potentials against a variety of physiological disorders. This study assesses acute and sub-chronic toxicity profile of hydro-methanolic extract of CS seeds using OECD guidelines. In acute toxicity study, mice were once orally administered 1000, 3000 and 5000 mg/kg body weight of CS extract. There were no any behavioral alterations or mortality recorded in CS treated groups. The LD50 value was more than 5000 mg/kg body weight. In the sub-chronic oral toxicity study, the animals were orally administered with CS extract (1000, 2000 and 3000mg/kg body weight) daily for 28 days whereas; vehicle control group received 0.5 % carboxy methyl cellulose. There was significant reduction in food intake, body weight gain and plasma lipid profiles of CS2 and CS3 (2000 and 3000 mg/kg body weight respectively) groups as compared to the control group. However, there were no alterations in haematological profile, relative organ weights, histology and plasma markers of damage of vital organs (heart, liver and kidney). The overall finding of this study indicates that CS extract is non-toxic up to 3000 mg/kg body weight and can be considered as safe for consumption. PMID:27847445

This study aims to investigate the impact of a health belief model (HBM)-based educational intervention on knowledge, beliefs, self-reported practices, gestational and postpartum weight in women with gestational diabetes mellitus (GDM). A cluster randomized controlled trial was performed, with randomization at the level of Primary Health Care centers in three Egyptian cities. Eligible women with GDM were enrolled at 24 weeks pregnancy. The intervention group (n = 103) received health education intervention based on the HBM construct. Control subjects (n = 98) received the usual care. The outcomes measured were: women's knowledge, beliefs, self-reported practices, gestational weight gain (GWG), and postpartum weight retention. Patients were investigated at baseline, at end of pregnancy, and at 6 weeks postpartum. After the intervention, percentages of women who had high knowledge and beliefs scores had significantly increased from less than 50 % to more than 70 % in the intervention group (p < 0.001). More women in the intervention group reported practicing exclusive breast feeding (85.4 %) and screening for T2DM (43.7 %) at 6 weeks postpartum compared to the control group (63.3 and 19.4 % respectively) (p < 0.001). More women with excessive body mass index in the intervention group (65 %) compared to the control group (11.6 %) were meeting recommended GWG (p < 0.001), and postpartum weight (37.7, and 20.3 % respectively) (p < 0.01). This intervention significantly improved knowledge, beliefs, self-reported practices, and gestational and postpartum weight in patients with GDM. Further research is needed for investigating the effectiveness of applying early, multi-phase, and longer intervention.

In observational studies, vegetarians generally have lower body weights compared with omnivores. However, weight changes that occur when vegetarian diets are prescribed have not been well quantified. We estimated the effect on body weight when vegetarian diets are prescribed. We searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials for articles through December 31, 2013. Additional articles were identified from reference lists. We included intervention trials in which participants were adults, interventions included vegetarian diets of ≥4 weeks' duration without energy intake limitations, and effects on body weight were reported. Two investigators independently extracted data using predetermined fields. Estimates of body weight change, comparing intervention groups to untreated control groups, were derived using a random effects model to estimate the weighted mean difference. To quantify effects on body weight of baseline weight, sex, age, study duration, study goals, type of diet, and study authorship, additional analyses examined within-group changes for all studies reporting variance data. We identified 15 trials (17 intervention groups), of which 4 included untreated controls. Prescription of vegetarian diets was associated with a mean weight change of -3.4 kg (95% CI -4.4 to -2.4; P<0.001) in an intention-to-treat analysis and -4.6 kg (95% CI -5.4 to -3.8; P<0.001) in a completer analysis (omitting missing post-intervention values). Greater weight loss was reported in studies with higher baseline weights, smaller proportions of female participants, older participants, or longer durations, and in studies in which weight loss was a goal. Using baseline data for missing values, I(2) equaled 52.3 (P=0.10), indicating moderate heterogeneity. When missing data were omitted, I(2) equaled 0 (P=0.65), indicating low heterogeneity. Studies are relatively few, with variable quality. The prescription of vegetarian diets reduces mean body weight, suggesting potential value for prevention and management of weight-related conditions.

Solutions for Wellness (SfW) is an educational 3-month program concerning nutrition and exercise for persons with psychiatric disorders on psychotropic medication, who have weight problems. This observational study assessed the impact of SfW on subjective well-being, weight and waist circumference (WC). Data was collected at 49 psychiatric clinics. Where the SfW program was offered patients could enter the intervention group; where not, the control group. Subjective well-being was measured by the Subjective Well-being under Neuroleptics scale (SWN), at baseline, at the end of SfW participation, and at a follow-up 6 months after baseline. Demographic, disease and treatment data was also collected. 314 patients enrolled in the SfW group, 59 in the control group. 54% of the patients had schizophrenia, 67% received atypical antipsychotics, 56% were female. They averaged 41 +/- 12.06 years and had a BMI of 31.4 +/- 6.35. There were significant differences at baseline between groups for weight, SWN total score and other factors. Stepwise logistic models controlling for baseline covariates yielded an adjusted non-significant association between SfW program participation and response in subjective well-being (SWN increase). However, statistically significant associations were found between program participation and weight-response (weight loss or gain < 1 kg) OR = 2; 95% CI [1.1; 3.7] and between program participation and WC-response (WC decrease or increase < 2 cm) OR = 5; 95% CI [2.4; 10.3]), at 3 months after baseline. SfW program participation was associated with maintaining or decreasing weight and WC but not with improved subjective well-being as measured with the SWN scale.

Accuracy of body image perception and preferred weight loss strategies in schizophrenia: a controlled pilot study.

Obesity in severely mentally ill (SMI) populations is an increasing problem, but there is no controlled data regarding the relationship between SMI and weight perception. Fifty patients with schizophrenia and 50 demographically matched control participants were recruited. Weight, height, and body image accuracy were assessed for all participants, and assessments of mood, psychotic symptom severity and anxiety, and preferred modes of weight loss were assessed for the schizophrenia sample. Patients with schizophrenia were significantly more likely to be obese than controls (46% vs. 18%, P < 0.005), and most patients expressed an interest in losing weight. Obese participants with schizophrenia underestimated their body size (11.0%) more than controls (4.9%) (P < 0.05). Patients with schizophrenia are more likely to underestimate their body size, independent of the effects of obesity. However, they also express concern about weight issues and willingness to participate in psychoeducational groups targeted at weight loss.

Patients with schizophrenia have a higher prevalence of metabolic syndrome (MetS) than the general population. Minimizing weight gain and metabolic abnormalities in a population with an already high prevalence of obesity is of clinical and social importance. This randomized controlled trial investigated the effect of monthly nutritional education on weight change and metabolic abnormalities among patients with schizophrenia in Japan. From July 2014 to December 2014, we recruited 265 obese patients who had a DSM-IV diagnosis of schizophrenia or schizoaffective disorder. Participants were randomly assigned to a standard care (A), doctor's weight loss advice (B), or an individual nutritional education group (C) for 12 months. The prevalence of MetS and body weight were measured at baseline and 12 months. After the 12-month treatment, 189 patients were evaluated, and the prevalence of MetS based on the ATP III-A definition in groups A, B, and C was 68.9%, 67.2%, and 47.5%, respectively. Group C showed increased weight loss (3.2 ± 4.5 kg) over the 12-month study period, and the change in weight differed significantly from that of group A; additionally, 26.2% of the participants in group C lost 7% or more of their initial weight, compared with 8.2% of those in group A. Individual nutrition education provided by a dietitian was highly successful in reducing obesity in patients with schizophrenia and could be the first choice to address both weight gain and metabolic abnormalities induced by antipsychotic medications.

In recent years, several pharmacological and psychosocial interventions have examined ways to prevent or treat weight gain in people receiving second-generation antipsychotics. While there has been some success, in general, results have not been compelling. Atomoxetine is a selective norepinepherine reuptake inhibitor found to be associated with appetite suppression. Therefore, we examined whether atomoxetine may be of benefit for those who have gained weight on either clozapine or olanzapine. The study was a double-blind, placebo-controlled trial. All participants received the same psychosocial platform: a structured support and exercise group. People with schizophrenia or schizoaffective disorder, on olanzapine or clozapine, who had gained at least 7% of their pre-clozapine or pre-olanzapine weight were eligible for a 24-week, randomized, parallel group, double-blind comparison of adjunctive atomoxetine or placebo. Thirty-seven participants (20 atomoxetine, 17 placebo) were randomized and 26 participants (14 atomoxetine, 12 placebo; 70.2%) completed the study. There were no significant group differences in baseline BMI (atomoxetine: 34.5±4.9; placebo: 35.7±7.0) or weight (atomoxetine: 102.2±15.7 kg; placebo: 104.3±17.5 kg). Both treatment groups showed modest, not significant, trends in weight loss, averaging about 2 kg. Gender or baseline antipsychotic treatment did not modify treatment effects on weight. Secondary outcomes included neuropsychological assessments, symptom assessments (BPRS, SANS) and safety assessments. Of these, only the group difference in Gordon distractibility test scores was statistically significant and favored treatment with atomoxetine. Atomoxetine is not effective for weight loss in this population, but both olanzapine and clozapine participants can lose weight with structured group support and exercise.

Background A challenge in the delivery of intensive obesity treatment is making care scalable. Little is known about whether the outcome of clinician-directed weight loss treatment can be improved by adding mobile technology. Methods We conducted a 2-arm, 12-month study (between October, 2007 and September, 2010). Seventy adults (body mass index [BMI] >25 and ≤ 40 kg/m2) were randomly assigned to either standard of care group treatment alone (Standard) or Standard + connective mobile technology system (+Mobile). Participants attended biweekly weight loss groups held by the VA outpatient clinic. The +Mobile group was provided personal digital assistants (PDAs) to self-monitor diet and physical activity; they also received biweekly coaching calls for 6 months. Weight was measured at baseline, 3, 6, 9, and 12 months follow-up. Results Sixty-nine adults received intervention (mean age 57.7 years, 85.5% male). A longitudinal intent-to-treat analysis indicated that the +Mobile group lost on average 8.6 more pounds (representing 3.1% more weight loss relative to the control) than the Standard group at each post-baseline time point, 95% CI [4.9, 12.2]. As compared to the Standard group, the +Mobile group had significantly greater odds of having lost 5% or more of their baseline weight at each post-baseline time point [OR= 6.5; 95% CI = 2.3, 18.6]. Conclusions The addition of a PDA and telephone coaching can enhance short-term weight loss in combination with an existing system of care. Mobile connective technology holds promise as a scalable delivery mechanism to augment the impact of clinician-delivered weight loss treatment. PMID:23229890

Necropsy of gastrointestinal tract of 125 free-range chickens from a subtropical and humid zone of northwestern India revealed four nematode spp. (Ascaridia galli, Heterakis gallinarum, Capillaria spp. and Cheilospirura hamulosa) and four cestode spp. (Raillietina cesticillus, Raillietina echinobothrida, Raillietina tetragona and Amoebotaenia cuneata) The overall prevalence of the helminth parasites was 72.0%. Amongst various helminth species encountered in the region, A. galli emerged out as the most prevalent, followed by H. gallinarum, R. cesticillus and R. echinobothrida. The impact of helminthic infections on body weight gain in growing chickens was investigated. One hundred growing chickens, aged 40 days were randomly assigned to two groups (treated and untreated controls) of 50 birds each. The birds in treated group were given fenbendazole at 7.5 mg per kg body weight in drinking water, while the birds in other group served as untreated controls. At the end of the 90 days of the field trial, the mean body weight gain of untreated controls was 1232.2 ± 7.28 g (13.7 g/day) compared with 1617.6 ± 5.43 g (18.0 g/day) in the treated group. It was associated with a significantly (P < 0.05) higher mean worm burden (32.92 ± 6.12) in untreated controls than the treated group (2.46 ± 1.14). The prevalences of helminthic species and their impact on body weight gain in growing backyard chickens have been discussed.

The aim of this study was to determine the effect of plant-based diets on weight loss. Participants were enrolled in a 6-mo, five-arm, randomized controlled trial in 2013 in South Carolina. Participants attended weekly group meetings, with the exception of the omnivorous group, which served as the control and attended monthly meetings augmented with weekly e-mail lessons. All groups attended monthly meetings for the last 4 mo of the study. Diets did not emphasize caloric restriction. Overweight adults (body mass index 25-49.9 kg/m(2); age 18-65 y, 19% non-white, and 27% men) were randomized to a low-fat, low-glycemic index diet: vegan (n = 12), vegetarian (n = 13), pesco-vegetarian (n = 13), semi-vegetarian (n = 13), or omnivorous (n = 12). Fifty (79%) participants completed the study. In intention-to-treat analysis, the linear trend for weight loss across the five groups was significant at both 2 (P < 0.01) and 6 mo (P < 0.01). At 6 mo, the weight loss in the vegan group (-7.5% ± 4.5%) was significantly different from the omnivorous (-3.1% ± 3.6%; P = 0.03), semi-vegetarian (-3.2% ± 3.8%; P = 0.03), and pesco-vegetarian (-3.2% ± 3.4%; P = 0.03) groups. Vegan participants decreased their fat and saturated fat more than the pesco-vegetarian, semi-vegetarian, and omnivorous groups at both 2 and 6 mo (P < 0.05). Vegan diets may result in greater weight loss than more modest recommendations. Copyright © 2015 Elsevier Inc. All rights reserved.

The aim of this study was to quantitatively evaluate the change in gait and body weight in the long term in patients with Prader-Willi Syndrome (PWS). Eight adults with PWS were evaluated at baseline and after 7 years. During this period patient participated an in- and out-patient rehabilitation programs including nutritional and adapted physical activity interventions. Two different control groups were included: the first group included 14 non-genetically obese patients (OCG: obese control group) and the second group included 10 age-matched healthy individuals (HCG: healthy control group). All groups were quantitatively assessed during walking with 3D-GA. The results at the 7-year follow-up revealed significant weight loss in the PWS group and spatial-temporal changes in gait parameters (velocity, step length and cadence). With regard to the hip joint, there were significant changes in terms of hip position, which is less flexed. Knee flexion-extension showed a reduction of flexion in swing phase and of its excursion. No changes of the ankle position were evident. As for ankle kinetics, we observed in the second session higher values for the peak of ankle power in terminal stance in comparison to the first session. No changes were found in terms of ankle kinetics. The findings demonstrated improvements associated to long-term weight loss, especially in terms of spatial-temporal parameters and at hip level. Our results back the call for early weight loss interventions during childhood, which would allow the development of motor patterns under normal body weight conditions. Copyright © 2014 Elsevier Ltd.

Ten ewe lambs (median age 11 months and average weight 29.2+/-2.5 kg) were used in the present study. They were divided into two groups: test (n=5) and control (n=5). Housing and all diets were identical. In the test group vitamin A was injected into the thigh muscle at a daily dose of 5000 IU/kg body weight for 16 days. The average final body weight of sheep in the test group was significantly (P<0.05) less than the control group. All animals were slaughtered at day 17. The lambs' feet were X-rayed to evaluate any difference for radiographic signs between test and control groups. No significant differences were seen for PCV, WBC, differential leukocyte count, and total serum protein between groups. There were no significant differences for serum AST, ALT, and ALP activities and serum calcium, inorganic phosphate, and magnesium concentrations between groups. Histological examination revealed an increased number of lipid droplets in the cytoplasm of the stellate cells of the liver in the test group. The results showed that daily administrations of vitamin A approximately 150 times greater than the daily requirement were well tolerated by sheep. Copyright 2009 Elsevier Ltd. All rights reserved.

Poor weight management may relate to a reduction in neurobehavioural control over food intake and heightened reactivity of the brain's neural reward pathways. Here we explore the neurophysiology of food-related visual cue processing in weight reduced and weight relapsed women by assessing differences in cortical arousal and attentional processing using a food-Stroop paradigm. 51 women were recruited into 4 groups: reduced-weight participants (RED, n=14) compared to BMI matched low-weight controls (LW-CTL, n=18); and weight relapsed participants (REL, n=10) compared to BMI matched high-weight controls (HW-CTL, n=9). Eating behaviour and body image questionnaires were completed. Two Stroop tasks (one containing food images, the other containing neutral images) were completed with record of electroencephalography (EEG). Differences in cortical arousal were found in RED versus LW-CTL women, and were seen during food task execution only. Compared to their controls, RED women exhibited lower relative delta band power (p=0.01) and higher relative beta band power (p=0.01) over the right frontal cortex (F4). Within the RED group, delta band oscillations correlated positively with self-reported habitual fat intake and with body shape dissatisfaction. As compared to women matched for phenotype but with no history of weight reduction, reduced-overweight/obese women show increased neurobehavioural control over external food cues and the inhibition of reward-orientated feeding responses. Insight into these self-regulatory mechanisms which attenuate food cue saliency may aid in the development of cognitive remediation therapies which facilitate long-term weight loss.

The aim of this study was to investigate the effect of an organic cannabis extract on β-cell secretory function in an in vivo diet-induced obese rat model and determine the associated molecular changes within pancreatic tissue. Diet-induced obese Wistar rats and rats fed on standard pellets were subcutaneously injected with an organic cannabis extract or the vehicle over a 28-day period. The effect of diet and treatment was evaluated using the intraperitoneal glucose tolerance tests (IPGTTs) and qPCR analysis on rat pancreata harvested upon termination of the experiment. The cafeteria diet induced an average weight difference of 32g and an overall increase in body weight in the experimental groups occurred at a significantly slower rate than the control groups, irrespective of diet. Area under the curve for glucose (AUC(g)) in the obese group was significantly lower compared to the lean group (p<0.001), with cannabis treatment significantly reducing the AUC(g) in the lean group (p<0.05), and remained unchanged in the obese group, relative to the obese control group. qPCR analysis showed that the cafeteria diet induced down-regulation of the following genes in the obese control group, relative to lean controls: UCP2, c-MYC and FLIP. Cannabis treatment in the obese group resulted in up-regulation of CB1, GLUT2, UCP2 and PKB, relative to the obese control group, while c-MYC levels were down-regulated, relative to the lean control group. Treatment did not significantly change gene expression in the lean group. These results suggest that the cannabis extract protects pancreatic islets against the negative effects of obesity.

HIV infection has been associated with low bone mineral density (BMD) in many cross-sectional studies, although longitudinal studies have not demonstrated accelerated bone loss. The cross-sectional studies may have been confounded by the failure to control for low body weight in HIV-infected patients. Our objective was to determine whether low body weight might explain the association of HIV infection with low BMD. MEDLINE and EMBASE were searched for English language studies published from 1966 to March 2007, and conference abstracts prior to 2007 were hand-searched. All studies reporting BMD and weight or body mass index in adult patients with HIV and a healthy age- and sex-comparable control group were included. Nine of 40 identified studies and one of 68 identified abstracts were eligible. We adjusted for the between-groups weight differences using regression coefficients from published cohorts of healthy men and women. On average, HIV-infected patients were 5.1 kg [95% confidence interval (CI), -6.8, -3.4; P < 0.001] lighter than controls. At all skeletal sites, unadjusted BMD was lower by 4.4-7.0% in the HIV-infected groups than the controls (P < 0.01). After adjustment for body weight, residual between-groups differences in BMD were small (2.2-4.7%) [lumbar spine, -0.02 (95% CI, -0.05, 0.01) g/cm2; P = 0.12; total hip, -0.02 (95% CI, -0.04, 0.00) g/cm2; P = 0.031; femoral neck, -0.04 (95% CI, -0.07, -0.01) g/cm2; P = 0.013; and total body, -0.03 (95% CI, -0.07, 0.01) g/cm2, P = 0.11]. HIV-infected patients are lighter than controls and low body weight may largely account for the high prevalence of low BMD reported in HIV-infected patients. However, in the setting of current treatment practice, HIV infection per se is not a risk factor for low BMD.

A stroke patient with hemiplegic gait is generally described as being slow and asymmetric. Body weight-supported treadmill training and backward gait training are recent additions to therapeutic gait trainings that may help improve gait in stroke patient with hemiplegic gait. Therefore, we examined the effect of progressive backward body weight-supported treadmill training on gait in chronic stroke patients with hemiplegic gait. Thirty subjects were divided to the experimental and control groups. The experimental group consisted of 15 patients and underwent progressive backward body weight-supported treadmill training. The control group consisted of 15 patients and underwent general treadmill gait training five times per week, for a total of four weeks. The OptoGait was used to analyze gait kinematics, and the dynamic gait index (DGI) and results of the 6-minute walk test were used as the clinical evaluation indicators. A follow-up test was carried out four weeks later to examine persistence of exercise effects. The experimental group showed statistically significant results in all dependent variables week four compared to the control group. However, until the eighth week, only the dependent variables, of affected step length (ASL), stride length (SL), and DGI differed significantly between the two groups. This study verified that progressive bodyweight-supported treadmill training had a positive influence on the temporospatial characteristics of gait and clinical gait evaluation index in chronic stroke patients.

Physical activity, nutrition, and sedentary behaviour combine to influence the risk of overweight among adolescents. This paper aims to identify psychosocial factors of different health behaviour patterns in adolescents and its association with overweight and weight control behaviours. The 3069 adolescents of both genders (average of 14.8 years old) from the 2010 Portuguese survey of Health Behaviour School-Aged Children (HBSC) answered the 2010 HBSC self-reported questionnaire. It used the cluster k-means (nonhierarchy method), qui-square, one-way ANOVA, and logistic regression. Three clusters with different behavioural patterns (physical activity, sedentary, and eating) composed the results obtained. The sedentary group (34%) had lower self-regulation, body satisfaction, health and wellness, family and classmates relationships, communication with the father than the other two groups. The active gamers (25%) had a smaller BMI but used more unhealthy weight control strategies than the other two groups. The healthy group (41%) was more motivated and more satisfied with school but was not different than the active gamers in most psychosocial variables. Differences were found between clusters for weight control behaviours and psychosocial variables. Different strategies for different patterns were necessary in order to promote obesity prevention and, simultaneously, target healthy lifestyle and wellbeing in adolescents. PMID:22811890

a case-control study was conducted to compare static plantar pressures and distribution of body weight across the two lower limbs, as well as the prevalence of gastrocnemius soleus equinus, in children with and without calcaneal apophysitis (Sever's disease). the participants were 54 boys enrolled in a soccer academy, of which eight were lost to follow-up. Twenty-two boys with unilateral Sever's disease comprised the Sever's disease group and 24 healthy boys constituted a control group. Plantar pressure data were collected using pedobarography, and gastrocnemius soleus equinus was assessed. peak pressure and percentage of body weight supported were significantly higher in the symptomatic feet of the Sever's disease group than in the asymptomatic feet of the Sever's disease group and the control group. Every child in the Sever's disease group had bilateral gastrocnemius equinus, while nearly all children in the control group had no equinus. high plantar foot pressures are associated with Sever's disease, although it is unclear whether they are a predisposing factor or a result of the condition. Gastrocnemius equinus may be a predisposing factor for Sever's disease. Further research is needed to identify other factors involved in the disease and to better understand the factors that contribute to abnormal distribution of body weight in the lower limbs.

Weight gained in young adulthood often persists throughout later life with associated chronic disease risk. Despite this, current population prevention strategies are not specifically designed for young adults. We designed and assessed the efficacy of an mHealth prevention program, TXT2BFiT, in preventing excess weight gain and improving dietary and physical activity behaviors in young adults at increased risk of obesity and unhealthy lifestyle choices. A two-arm, parallel-group randomized controlled trial was conducted. Subjects and analyzing researchers were blinded. A total of 250 18- to 35-year-olds with a high risk of weight gain, a body mass index (BMI) of 23.0 to 24.9 kg/m(2) with at least 2 kg of weight gain in the previous 12 months, or a BMI of 25.0 to 31.9 kg/m(2) were randomized to the intervention or control group. In the 12-week intervention period, the intervention group received 8 text messages weekly based on the transtheoretical model of behavior change, 1 email weekly, 5 personalized coaching calls, a diet booklet, and access to resources and mobile phone apps on a website. Control group participants received only 4 text messages and printed dietary and physical activity guidelines. Measured body weight and height were collected at baseline and at 12 weeks. Outcomes were assessed via online surveys at baseline and at 12 weeks, including self-reported weight and dietary and physical activity measures. A total of 214 participants-110 intervention and 104 control-completed the 12-week intervention period. A total of 10 participants out of 250 (4.0%)-10 intervention and 0 control-dropped out, and 26 participants (10.4%)-5 intervention and 21 control-did not complete postintervention online surveys. Adherence to coaching calls and delivery of text messages was over 90%. At 12 weeks, the intervention group were 2.2 kg (95% CI 0.8-3.6) lighter than controls (P=.005). Intervention participants consumed more vegetables (P=.009), fewer sugary soft drinks (P=.002), and fewer energy-dense takeout meals (P=.001) compared to controls. They also increased their total physical activity by 252.5 MET-minutes (95% CI 1.2-503.8, P=.05) and total physical activity by 1.3 days (95% CI 0.5-2.2, P=.003) compared to controls. The TXT2BFiT low-intensity intervention was successful in preventing weight gain with modest weight loss and improvement in lifestyle behaviors among overweight young adults. The short-term success of the 12-week intervention period shows potential. Maintenance of the behavior change will be monitored at 9 months.

This study aims to describe the association between dietary habits and weight status and the interest in food and science. We examined in a cross-sectional study 525 children aged between 8 and 18 years, who attended the Brussels Food Fair or the Belgian Science Day in 2013. They were divided into three groups: special interest in science, special interest in food, and a general control group. They completed a questionnaire, and body parameters were measured. The weight status of the children was identified using the growth charts and the calculated BMI. In total, 525 children were included: 290 children in the reference group, 194 in the food group, and 41 in the science group. The prevalence of overweight and obesity was 28% in the general control group, 14% in the food group, and 15% in the science group. Breakfast and dinner were skipped more often by children with overweight or obesity. Children from the food and science groups had more sweets and meat, had less fruit, and skipped less meals. In our study, 28% of the reference group had overweight or obesity. The children with special interest in food or science differed from the control group.

Background Obesity exacerbates the age-related decline in insulin sensitivity and is associated with risk for cardiometabolic syndrome in older adults; however, the appropriate treatment for obese older adults is controversial. Objective To determine the independent and combined effects of weight loss and exercise on cardiometabolic risk factors in obese older adults. Design One-hundred-seven obese (BMI≥30 kg/m2) older (≥65 yrs) adults with physical frailty were randomized to control group, diet group, exercise group, and diet-exercise group for 1 year. Outcomes for this study included change in insulin sensitivity index (ISI), glucose tolerance, central obesity, adipocytokines, and cardiometabolic syndrome. Results Although similar increases in ISI occurred in the diet-exercise and diet groups at 6 months, the ISI improved more in the diet-exercise than in the diet group at 12 months (2.4 vs. 1.2; between-group difference, 1.2; 95% CI, 0.2-2.1); no changes in ISI occurred in both exercise and control groups. The diet-exercise and diet groups had similar improvements in insulin area under the curve (AUC) (−2.9 and −2.9 ×103mg.min/dl), glucose AUC (−1.4 and −2.2×103mg.min/dl), visceral fat (−787 and −561 cm3), tumor-necrosis factor (−17.0 and −12.8 pg/mL), adiponectin (5.0 and 4.0 ng/mL), waist circumference (−8.2 and −8.4 cm), triglyceride (−30.7 and −24.3 g/dL), and systolic/diastolic BP (−15.9 and −13.1/−4.9 and −6.7 mmHg), while no changes in these parameters occurred in both exercise and control groups. The cardiometabolic syndrome prevalence decreased by 40% in the diet-exercise and by 15% in the diet group. Body weight decreased similarly in the diet-exercise and diet groups (−8.6 and −9.7kg) but not in the exercise and control groups. Conclusions In frail, obese older adults, lifestyle interventions associated with weight loss improve insulin sensitivity and other cardiometabolic risk factors, but continued improvement in insulin sensitivity is only achieved when exercise training is added to weight loss.

Assessing the prevalence of weight loss attempts in Beirut, Lebanon, a country characterized by a diversity of ethnic and religious groups and examining the interplay between ethnicity, body mass index (BMI) and weight perception and their relationship to weight loss behavior. A school-based survey of risk behaviors conducted among secondary students (grade 10-12) in 1997. Subjects consisted of 827 boys and girls, aged 15 to 23 years, the majority of whom were Moslems (65.4%). Multiple logistic regression was used to estimate the association between ethnicity and weight perception with the likelihood of trying to lose weight controlling for BMI and a number of potential covariates. The prevalence of weight loss attempts was 19.1% and 42.6% in boys and girls respectively. Christians were more likely to perceive themselves as overweight and to attempt weight loss than Moslems across all BMI levels, however this trend was significant in the underweight category. While controlling for BMI did not change appreciably the results observed, after controlling for weight perception, ethnic differences in weight-loss behavior disappeared. Findings of the study suggest that whereas actual weight may constitute only partially the driving force for differentials by ethnicity, the perception of body weight acts as a mediating factor in the relationship between ethnicity and weight loss behavior. Understanding the disparities in weight management behavior across various adolescent groups is key to develop culturally appropriate educational and intervention programs for the youths.

Brackground: The safety and tolerability of very low-calorie-ketogenic (VLCK) diets are a current concern in the treatment of obese type 2 diabetes mellitus (T2DM) patients. Objective: Evaluating the short-term safety and tolerability of a VLCK diet (<50 g of carbohydrate daily) in an interventional weight loss program including lifestyle and behavioral modification support (Diaprokal Method) in subjects with T2DM. Methods: Eighty-nine men and women, aged between 30 and 65 years, with T2DM and body mass index between 30 and 35 kg m−2 participated in this prospective, open-label, multi-centric randomized clinical trial with a duration of 4 months. Forty-five subjects were randomly assigned to the interventional weight loss (VLCK diet), and 44 to the standard low-calorie diet. Results: No significant differences in the laboratory safety parameters were found between the two study groups. Changes in the urine albumin-to-creatinine ratio in VLCK diet were not significant and were comparable to control group. Creatinine and blood urea nitrogen did not change significantly relative to baseline nor between groups. Weight loss and reduction in waist circumference in the VLCK diet group were significantly larger than in control subjects (both P<0.001). The decline in HbA1c and glycemic control was larger in the VLCK diet group (P<0.05). No serious adverse events were reported and mild AE in the VLCK diet group declined at last follow-up. Conclusions: The interventional weight loss program based on a VLCK diet is most effective in reducing body weight and improvement of glycemic control than a standard hypocaloric diet with safety and good tolerance for T2DM patients.

Low-grade inflammation has been repeatedly associated with both excess weight and psychosis. However, no previous studies have addressed the direct effect of body mass index (BMI) on basal serum cytokines in individuals with first-episode psychosis (FEP). The aim of this study is to analyze the effect of BMI on basal serum cytokine levels in FEP patients and control subjects, separating the total sample into two groups: normal-weight and overweight individuals. This is a prospective and open-label study. We selected 75 FEP patients and 75 healthy controls with similar characteristics to patients according to the following variables: sex, age, and cannabis and tobacco consumption. Both controls and patients were separated into two groups according to their BMI: subjects with a BMI under 25 were considered as normal weight and those with a BMI equal to or more than 25 were considered as overweight. Serum levels of 21 cytokines/chemokines were measured at baseline using the Human High Sensitivity T Cell Magnetic Bead Panel protocol from the Milliplex® Map Kit. We compared the basal serum levels of the 21 cytokines between control and patient groups according to their BMI. In the normal-weight group, IL-8 was the only cytokine that was higher in patients than in the control group (p = 0.001), whereas in the overweight group, serum levels of two pro-inflammatory cytokines (IL-6, p = 0.000; IL-1β, p = 0.003), two chemokines (IL-8, p = 0.001; MIP-1β, p = 0.001), four Th-1 and Th-2 cytokines (IL-13, p = 0.009; IL-2, p = 0.001; IL-7, p = 0.001; IL-12p70, p = 0.010), and one Type-3 cytokine (IL-23, p = 0.010) were higher in patients than in controls. Most differences in the basal serum cytokine levels between patients and healthy volunteers were found in the overweight group. These findings suggest that excess weight can alter the homeostasis of the immune system and therefore may have an additive pro-inflammatory effect on the one produced by psychosis in the central nervous system.

Background: Low birth weight (LBW) is an important public health problem in undernourished populations. Objective: We tested whether improving women's dietary micronutrient quality before conception and throughout pregnancy increases birth weight in a high-risk Indian population. Design: The study was a nonblinded, individually randomized controlled trial. The intervention was a daily snack made from green leafy vegetables, fruit, and milk (treatment group) or low-micronutrient vegetables (potato and onion) (control group) from ≥90 d before pregnancy until delivery in addition to the usual diet. Treatment snacks contained 0.69 MJ of energy (controls: 0.37 MJ) and 10–23% of WHO Reference Nutrient Intakes of β-carotene, riboflavin, folate, vitamin B-12, calcium, and iron (controls: 0–7%). The primary outcome was birth weight. Results: Of 6513 women randomly assigned, 2291 women became pregnant, 1962 women delivered live singleton newborns, and 1360 newborns were measured. In an intention-to-treat analysis, there was no overall increase in birth weight in the treatment group (+26 g; 95% CI: −15, 68 g; P = 0.22). There was an interaction (P < 0.001) between the allocation group and maternal prepregnant body mass index (BMI; in kg/m2) [birth-weight effect: −23, +34, and +96 g in lowest (<18.6), middle (18.6–21.8), and highest (>21.8) thirds of BMI, respectively]. In 1094 newborns whose mothers started supplementation ≥90 d before pregnancy (per-protocol analysis), birth weight was higher in the treatment group (+48 g; 95% CI: 1, 96 g; P = 0.046). Again, the effect increased with maternal BMI (−8, +79, and +113 g; P-interaction = 0.001). There were similar results for LBW (intention-to-treat OR: 0.83; 95% CI: 0.66, 1.05; P = 0.10; per-protocol OR = 0.76; 95% CI: 0.59, 0.98; P = 0.03) but no effect on gestational age in either analysis. Conclusions: A daily snack providing additional green leafy vegetables, fruit, and milk before conception and throughout pregnancy had no overall effect on birth weight. Per-protocol and subgroup analyses indicated a possible increase in birth weight if the mother was supplemented ≥3 mo before conception and was not underweight. This trial was registered at www.controlled-trials.com/isrctn/ as ISRCTN62811278. PMID:25332324

The effects of 14 days of space flight on the glucose transporter protein (GLUT-4) were studied in the plantaris muscle of growing 9-week-old, male Sprague Dawley rats. The rats were randomly separated into five groups: pre-flight vivarium ground controls (PF-VC) sacrificed approximately 2 h after launch; flight groups sacrificed either approximately 5 h (F-R0) or 9 days (F-R9) after the return from space; and synchronous ground controls (SC-R0 and SC-R9) sacrificed at the same time as the respective flight groups. The flight groups F-R0 and F-R9 were exposed to micro-gravity for 14 days in the Spacelab module located in the cargo bay of the shuttle transport system - 58 of the manned Space Shuttle for the NASA mission named ''Spacelab Life Sciences 2''. Body weight and plantaris weight of SC-R0 and F-R0 were significantly higher than those of PF-VC. Neither body weight nor plantaris muscle weight in either group had changed 9 days after the return from space. As a result, body weight and plantaris muscle weight did not differ between the flight and synchronous control groups at any of the time points investigated. The GLUT-4 content (cpm/µg membrane protein) in the plantaris muscle did not show any significant change in response to 14 days of space flight or 9 days after return. Similarly, citrate synthase activity did not change during the course of the space flight or the recovery period. These results suggest that 14 days of space flight does not affect muscle mass or GLUT-4 content of the fast-twitch plantaris muscle in the rat.

It has been found that honey ameliorates cardiovascular risk factors in healthy individuals and in patients with elevated risk factors. The present study investigated the effect of natural honey on total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triacylglycerole, C-reactive protein (CRP), fasting blood glucose (FBG), and body weight in overweight individuals. There were 55 patients, overweight or obese, who were randomly recruited into the study and assigned into two groups: control group (17 subjects) and experimental group (38 subjects). Patients in the control group received 70 g of sucrose daily for a maximum of 30 days and patients in the experimental group received 70 g of natural honey for the same period. In the control and experimental groups, body weight, body mass index, body fat weight, total cholesterol, LDL-C, HDL-C, triacylglycerole, FBG, and CRP were measured before treatment and at day 31 after the commencement of treatment. Results showed that honey caused a mild reduction in body weight (1.3%) and body fat (1.1%). Honey reduced total cholesterol (3%), LDL-C (5.8), triacylglycerole (11%), FBG (4.2%), and CRP (3.2%), and increased HDL-C (3.3%) in subjects with normal values, while in patients with elevated variables, honey caused reduction in total cholesterol by 3.3%, LDL-C by 4.3%, triacylglycerole by 19%, and CRP by 3.3% (p < 0.05). It is our conclusion that consumption of natural honey reduces cardiovascular risk factors, particularly in subjects with elevated risk factors, and it does not increase body weight in overweight or obese subjects.

Administering monosodium glutamate (MSG) to neonatal rodents induces obesity and type 2 diabetes. In addition, several studies have shown that MSG administered to pregnant animals can cross the placenta and reach the foetus. The present study was performed to investigate the effects of administering MSG to pregnant ICR mice on dam and neonatal growth. Pregnant mice were treated with 60 or 120 mg MSG once daily from day 5 of pregnancy to one day before parturition by subcutaneous injection. In addition, the body weights of the neonates were determined until nine weeks of age. The birth weights of neonates were not different between the control and MSG-treated groups. However, MSG treatment resulted in a lower body weight gain of neonates during lactation. In addition, this underweight of the MSG-treated group at weaning returned to normal compared with the control group at five weeks of age. Cross-fostering experiments indicated that the lower body weight gain of neonates in the MSG-treated group during lactation was due to its effects on the dam. Serum prolactin levels and mammary gland development of the mice were examined next to determine the reasons for this lactation problem. Although there were no differences in prolactin levels, morphological analyses of the mammary glands revealed apparent differences, including low numbers and altered phenotype of alveoli, between the control and MSG-treated groups. Taken together, our results show that treating pregnant mice with excess MSG induced lower neonate body weight gain during lactation. © The Author(s) 2015.

Worksites are potentially effective locations for obesity control because they provide opportunities for group intervention and social support. Studies are needed to identify effective interventions in these settings. We examined the effects of a multicomponent lifestyle intervention on weight loss and prevention of regain in 4 worksites (2 intervention and 2 control sites). Overweight and obese employees (n = 133) enrolled in this pilot worksite-randomized controlled trial with a 0-6-mo weight-loss phase and a 6-12-mo structured weight-maintenance phase. The intervention combined recommendations to consume a reduced-energy, low-glycemic load, high-fiber diet with behavioral change education. Outcome measurements included changes in body weight and cardiometabolic risk factors. The mean ± SEM weight loss was substantial in intervention participants, whereas control subjects gained weight (-8.0 ± 0.7 compared with +0.9 ± 0.5 kg, respectively; P < 0.001), and 89% of participants completed the weight-loss phase. Intervention effects were not significant at the 0.05 level but would have been at the 0.10 level (P = 0.08) in a mixed model in which the worksite nested within group was a random factor. There were also significant improvements in cardiometabolic risk factors in intervention compared with control subjects regarding fasting total cholesterol, glucose, systolic blood pressure, and diastolic blood pressure (P ≤ 0.02 for each). No significant weight regain was observed in participants who enrolled in the structured weight-maintenance program (0.5 ± 0.7 kg; P = 0.65), and overweight and obese employees in intervention worksites who were not enrolled in the weight-loss program lost weight compared with subjects in control worksites (-1.3 ± 0.5 compared with +0.7 ± 0.2 kg, respectively; P = 0.02). Worksites can be effective for achieving clinically important reductions in body weight and improved cardiometabolic risk factors. This trial was registered at clinicaltrials.gov as NCT01470222.

Resistance exercise using free weights or weight machines improves glycaemic control and strength in people with type 2 diabetes. Resistance band training is potentially less expensive and more accessible, but the effects of resistance band training on glycaemic control and strength in this population are not well understood. This paper aims to systematically review and meta-analyse the effect of resistance band training on haemoglobin A1c (HbA1c) and strength in adults with type 2 diabetes. Database searches were performed in August 2013 (MEDLINE, SPORTDiscus, EMBASE, and CINAHL). Reference lists of eligible articles were hand-searched for additional studies. Randomised trials evaluating the effects of resistance band training in adults with type 2 diabetes on HbA1c or objectively measured strength were selected. Baseline and post-intervention HbA1c and strength were extracted for the intervention and control groups. Details of the exercise interventions and methodological quality were collected. Seven trials met inclusion criteria. Post-intervention-weighted mean HbA1c was nonsignificantly lower in exercise groups compared to control groups [weighted mean difference (WMD) = -0.18 percentage points (-1.91 mmol/mol); P = 0.27]. Post-intervention strength was significantly higher in the exercise groups compared to the control groups in the lower extremities (WMD = 21.90 kg; P < 0.0001), but not in the upper extremities (WMD = 2.27 kg; P = 0.13) or handgrip (WMD = 1.98 kg; P = 0.46). All trials were small and had methodological limitations. Resistance band training did not significantly affect HbA1c, upper extremity, or handgrip strength but significantly increased the strength of the lower extremities in people with type 2 diabetes.

Obesity among Black women continues to exceed that of other women. Most weight loss programs created without reference to specific cultural contexts are less effective for Black than White women. Weight control approaches accessible to Black women and adapted to relevant cultural contexts are important for addressing this problem. This paper reports the final results of SisterTalk, the randomized controlled trial of a cable TV weight control program oriented toward Black women. A five group design included a comparison group and a 2 × 2 factorial comparison of a) interactive vs. passive programming and b) telephone social support vs no telephone support, with 12 weekly initial cable TV programs followed by 4 monthly booster videos. At baseline, 3, 8, and 12 months post randomization, telephone and in person surveys were administered on diet, physical activity, and physical measurements of height and weight were taken to calculate body mass index (BMI). Analysis of variance (ANOVA) was used to examine differences over time, and between treatment and comparison groups. Dose variables reflecting use of the TV/video and written materials were also assessed. At 3 months, BMI, weight, and dietary fat were significantly lower and physical activity significantly higher among women exposed to the Cable TV intervention compared to the wait-list comparison group. Significant dietary fat differences were still observed at 8 and 12 month evaluations, but not BMI or physical activity differences. Main effects were not observed for interactive programming or enhanced social support at any time point. Within the intervention group, higher watching of the TV series and higher reading of educational materials were both (separately) associated with significantly lower dietary fat. Cable TV was an effective delivery channel to assist Black women with weight control, increasing physical activity and decreasing dietary fat during an initial intervention period, but only dietary changes persisted Enhanced social support and the ability to interact with others during the show were not effective complementary intervention components as conducted in this trial. Future research to strengthen the ability of this approach to achieve long term effects may offer even more promising outcomes.

Increased fructose consumption is linked to insulin resistance, weight gain, hyperlipidemia and hypertension. Although the advantages of several dietary restriction regimens have been demonstrated, the effects of alternate-day fasting (ADF) on fructose-induced insulin resistance have not yet been studied. This study is based on a new modification on ADF by combining the fructose-rich solution (10% w/v) and regular mice diet. Mice were randomly allocated into four groups: ADF50% (50% restriction in chow food intake but ad libitum fructose drink), ADF100% (100% restriction for chow food but ad libitum fructose drink), control (ad libitum chow food intake plus tap water) and daily food and fructose (DFF) (had free access to both chow and fructose solution). Biweekly fasting blood sugar (FBS), glucose tolerance test (GTT) and insulin tolerance test (ITT) were conducted. All groups gained weight during the study (p < 0.05). Body weights of DFF and control groups did not differ from that of ADF groups, but ADF50% gained more (p < 0.01) weights than ADF100% through the study. Total calorie intake (feed + fast days) of ADF50% was higher than that of ADF100% (p < 0.001) and control (p < 0.03). In addition, ADF groups consumed more energy than the control and DFF groups in feed (ad libitum) days (p < 0.05). At the end of the study, the mean FBS levels in the control and ADF100% groups were similar and significantly lower in relation to that of DFF and ADF50% groups (p < 0.01). Measurements of area under the curve in GTT and ITT revealed that the ADF100% group was more insulin-sensitive than the DFF and ADF50% groups. In conclusion, these data suggest that the ADF100% improves fructose-induced insulin resistance in mice. © 2013 Blackwell Verlag GmbH.

Explanatory evaluation of interventions for prevention of weight gain is required beyond changes in weight, to determine for whom the intervention works and the underlying mechanisms of change. It was hypothesised that participant characteristics moderate intervention effect on weight change and improved eating and physical activity behaviours during the 3-month program mediate the relationship between intervention and weight. In our randomised controlled trial, young adults at risk of weight gain (n = 250) were assigned either to an intervention group that received a 3-month mHealth (TXT2BFiT) program with 6-month maintenance or to a control group. Data were collected via online self-report surveys. Hypothesised moderators and mediators of the intervention effect on weight were independently assessed in PROCESS macro models for 3 and 9-month weight change. Males (P = 0.01), mid-20s age group (P = 0.04), and higher income earners (P = 0.02) moderated intervention effects on weight change at 3-months and males only at 9-months (P = 0.02). Weight change at 3 (-1.12 kg) and 9-months (-1.38 kg) remained significant when 3-month nutrition and physical activity behaviours were specified as mediators (P <0.01 and P = 0.01 respectively). Indirect paths explained 39% (0.72/1.85 kg) and 40 % (0.92/2.3 kg) of total effect on weight change at 3 and 9-months respectively. Increased vegetable intake by intervention group at 3-months accounted for 19 and 17% and decreased sugar-sweetened beverages accounted for 8 and 13% of indirect weight change effects at 3 and 9-months respectively. TXT2BFiT was effective for both young men and women. Small sustained behavioural changes, including increased vegetable intake and decreased sugar-sweetened beverages consumption significantly mediated the intervention's effects on weight change. Improved eating behaviours and increased physical activity accounted for approximately 40% of the weight change. The trial is registered with the Australian New Zealand Clinical Trials Registry ( ACTRN12612000924853 ).

Affiliation with weight conscious peer groups is theorized to increase thin-ideal internalization through socialization processes. However, selection effects could contribute if genetic and/or environmental predispositions lead to affiliation with weight conscious peers. Co-twin control methodology was used to examine socialization and selection effects in 614 female twins (ages 8–15) from the Michigan State University Twin Registry (MSUTR). Thin-ideal internalization and peer group characteristics were assessed via self-report questionnaires. Results suggested the presence of both socialization and selection effects. In terms of socialization, twins who reported increased exposure to weight conscious peers relative to their co-twins had elevated thin-ideal internalization scores, regardless of zygosity. However, associations between weight conscious peers and thin-ideal internationalization within twin pairs were attenuated, suggesting that genetic and shared environmental selection effects also contribute. Findings significantly extend previous work by confirming the presence of socialization processes and highlighting selection processes to be examined in future longitudinal research. PMID:26859605

to examine the effect of individual counselling on diet and physical activity from pregnancy to six months post partum, or from birth to six months post partum, on weight retention among Taiwanese women. a randomised controlled trial assigned participants to two experimental groups [from pregnancy to six months post partum (EP) and from birth to six months post partum (EPP)] and one comparison group. a 3900-bed medical centre in northern Taiwan with around 3000 births annually. a sample of 189 women who had regular check-ups during pregnancy and gave birth at the medical centre. the comparison group received the routine outpatient department obstetric educational programme. The EP group attended regularly scheduled clinic visits with individualised dietary and physical activity education plans from 16 gestational weeks to six months post partum, and received on brochure. The EPP group received the same educational intervention as the EP group from 24-48 hours after birth to six months post partum. body weight, body mass index, health-promoting behaviour and psycho-social variables (self-efficacy, body image, depression and social support). average gestational weight gain was 14.02, 15.27 and 16.22 kg in the three EP, EPP and comparison groups respectively, and average weight retention at six months post partum was 2.34, 4.06 and 5.08 kg in the three groups, respectively. a diet and physical activity intervention from pregnancy is effective for reducing post-pregnancy weight retention. the findings of the present study should be taken into consideration when incorporating significant others and weight-loss maintenance strategies with interventions for a healthier family lifestyle.

Injuries may cause unilateral deterioration of brain areas related to postural control resulting in lateralized motor disability with abnormal asymmetry in weight-bearing distribution. Although overloading toward the nonaffected limb has been described as the preferred posture among individuals with hemiparesis, characterization of the weight-bearing asymmetry is poorly and indirectly described. Therefore, this study aimed to describe weight-bearing distribution during upright stance, establishing criteria to consider asymmetry in hemiparesis when analyzed within the limits defined by controls matched by age and gender. Forty subjects with (n = 20) or without hemiparesis (n = 20) were included in procedures to record weight-bearing values between hemibodies, and these values were used to calculate a symmetry ratio. Control presented 95% confidence interval (CI) of the mean for symmetry ratio ranging from 0.888 to 1.072, defining limits to symmetry. Four subjects with hemiparesis (20%) had symmetry ratios inside limits defined by controls (i.e., weight-bearing symmetrically distributed), and 11 (55%) subjects without hemiparesis showed symmetry ratios outside the limits, suggesting asymmetrical weight-bearing distribution. It was concluded that asymmetry, when present in a control group, was more frequently overloading nonpredominantly used hemibody (nondominant side), differing from a hemiparesis group commonly forced to assume the nonaffected side as the predominantly used hemibody and where the overload was observed.

Chemicals that occur in vegetal food and known as phytoestrogens, because of their structures similarity to estrogen, have benefits on chronic diseases. Despite this, when they are taken at high amounts, they can cause harmful effects on endocrine system of human and animals. In this study, it has been intended to determine the estrogenic potencies of phytoestrogens apigenin, phloretin and myricetin whose affinities for estrogen receptors in vitro. The female rats divided into 17 groups, each containing six rats. There was a negative control group and there were positive control dose groups which contains ethinyl estradiol, ethinyl estradiol+tamoxifen and genistein. The other dose groups which were tested for estrogenic activity contains apigenin, myricetin and phloretin All chemicals have been given to Wistar immature female rats with oral gavage for 3 consecutive days. By using uterotrophic analysis, uterus wet and blotted weights, vaginal opening, uterus length of female rats has been recorded at the end of the experiment. For detect of cell response, luminal epithelium height, gland number and lactoferrin intensity in luminal epithelium of uterus were evaluated. Biochemical analysises in blood were performed. Relative uterus weights of rats in 100 mg/kg/day dose group of myricetin were statistically increased according to vehicle control and positive control groups. In dose groups of apigenin and phloretin it was found that there were cell responses in uterus. All treatment groups had a significant difference in the high intensity of lactoferrin and uterine gland count compared to oil control group. There was no difference between phloretin and apigenin treatment groups in uterine weight statictically. Uterine heights were increased in positive control groups and 100 mg/kg/day dose group of myricetin. Epithelial cell heights were increased in treatment groups except apigenin and phloretin dose groups. There was no difference between all treatment groups in vaginal opening values according to positive control. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

The transitional period from late adolescence to early adulthood is a vulnerable period for weight gain, with a twofold increase in overweight/obesity during this life transition. In the United States, approximately one-third of young adults have obesity and are at a high risk for weight gain. To describe the design and rationale of a National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) sponsored randomized, controlled clinical trial, the Healthy Body Healthy U (HBHU) study, which compares the differential efficacy of three interventions on weight loss among young adults aged 18-35years. The intervention is delivered via Facebook and SMS Text Messaging (text messaging) and includes: 1) targeted content (Targeted); 2) tailored or personalized feedback (Tailored); or 3) contact control (Control). Recruitment is on-going at two campus sites, with the intervention delivery conducted by the parent site. A total of 450 students will be randomly-assigned to receive one of three programs for 18months. We hypothesize that: a) the Tailored group will lose significantly more weight at the 6, 12, 18month follow-ups compared with the Targeted group; and that b) both the Tailored and Targeted groups will have greater weight loss at the 6, 12, 18month follow-ups than the Control group. We also hypothesize that participants who achieve a 5% weight loss at 6 and 18months will have greater improvements in their cardiometabolic risk factors than those who do not achieve this target. We will examine intervention costs to inform implementation and sustainability other universities. Expected study completion date is 2019. This project has significant public health impact, as the successful translation could reach as many as 20 million university students each year, and change the current standard of practice for promoting weight management within university campus communities.

To determine if community-based, low-cost interventions during third trimester of pregnancy can reduce the incidence of low birth weight babies. In a case control study, 290 pregnant women from a slum area were registered in the beginning of third trimester of pregnancy and provided full antenatal care comprising fortnightly check up, one IFA tablet daily, counseling for minimum one-and-a-half hour post-lunch rest in left lateral position, additional diet to ensure minimum 2,200 kcal per day, and management of clinical conditions, if any. An equal number of pregnant women belonging to the same slum area were registered as control who received routine antenatal services from the existing health care facilities. The birth weight of the babies in the two groups were recorded and compared. Test of significance and correlation coefficient were applied to the data. Mean birth weight of the babies of the Subjects was 2.76 kg (SD 0.39) compared to mean birth weight of 2.57 kg (SD 0.36) of the babies in the Control group. Incidence of low birth weight babies among subjects who consumed minimum 2,400 kcal per day, had one-and-a-half hour post-lunch rest in left lateral position and who consumed one tablet of IFA (100 mg iron and 5 mg folic acid) per day during the last trimester of pregnancy was lower (17.6 %) as compared with women in the Control group (36.2 %). The difference in the mean birth weight of newborns of the two groups was statistically significant (t = 2.52, p < 0.01). Incidence of low birth weight babies can be significantly reduced by providing simple, low-cost care to pregnant women during the last trimester of pregnancy in the community setting.

This study analysed the effects of upright weight bearing and the knee flexion angle on patellofemoral indices, determined using magnetic resonance imaging (MRI), in patients with patellofemoral instability (PI). Healthy volunteers (control group, n = 9) and PI patients (PI group, n = 16) were scanned in an open-configuration MRI scanner during upright weight bearing and supine non-weight bearing positions at full extension (0° flexion) and at 15°, 30°, and 45° flexion. Patellofemoral indices included the Insall-Salvati Index, Caton-Deschamp Index, and Patellotrochlear Index (PTI) to determine patellar height and the patellar tilt angle (PTA), bisect offset (BO), and the tibial tubercle-trochlear groove (TT-TG) distance to assess patellar rotation and translation with respect to the femur and alignment of the extensor mechanism. A significant interaction effect of weight bearing by flexion angle was observed for the PTI, PTA, and BO for subjects with PI. At full extension, post hoc pairwise comparisons revealed a significant effect of weight bearing on the indices, with increased patellar height and increased PTA and BO in the PI group. Except for the BO, no such changes were seen in the control group. Independent of weight bearing, flexing the knee caused the PTA, BO, and TT-TG distance to be significantly reduced. Upright weight bearing and the knee flexion angle affected patellofemoral MRI indices in PI patients, with significantly increased values at full extension. The observations of this study provide a caution to be considered by professionals when treating PI patients. These patients should be evaluated clinically and radiographically at full extension and various flexion angles in context with quadriceps engagement. Explorative case-control study, Level III.

The present study was undertaken to evaluate the protective effect of turmeric powder on arsenic toxicity through mice model. Swiss albino male mice were divided into four groups. The first group was used as control, while groups 2, 3, and 4 were treated with turmeric powder (T, 50 mg/kg body weight/day), sodium arsenite (Sa, 10 mg/kg body weight/day) and turmeric plus Sa (T+Sa), respectively. Results showed that oral administration of Sa reduced the weight gain of the mice compared to the control group and food supplementation of turmeric prevented the reduction of weight gain. Turmeric abrogated the Sa-induced elevation of serum urea, glucose, triglyceride (TG) level and alanine aminotransferase (ALT) activity except the activity of alkaline phosphatase (ALP). Turmeric also prevented the Sa-induced perturbation of serum butyryl cholinesterase activity (BChE). Therefore, ameliorating effect of turmeric on Sa-treated mice suggested the future application of turmeric to reduce or to prevent arsenic toxicity in human.

This study aimed to evaluate coadministration of Duddingtonia flagrans and Monacrosporium thaumasium in a sodium alginate matrix for controlling gastrointestinal helminths in young and adult sheep in the semiarid region of northeastern Brazil. An area of 1ha was divided into two paddocks, in which two experimental groups (fungus and control) were formed, each consisting of six adult females and ten young males. In each group, two subgroups were formed in accordance with the animal category (adult or young). In the fungus group, each animal received 3g of pellets containing 0.6g of fungal mycelium, with 0.3g of D. flagrans and 0.3g of M. thaumasium for each 10 kg of body weight, in their feed twice a week, for six months. In the control group, each animal received 3g of pellets without fungus for each 10 kg of body weight, in their feed twice a week, for six months, serving as a witness group. Reductions in numbers of eggs per gram of feces of 76% among the adult sheep in the fungus group and 83% among the young sheep in the fungus group were observed, in comparison with their respective control subgroups. The groups that received these fungi needed less salvage deworming and presented better packed cell volume percentages, better weight gain and lower levels of L3/kg dry matter in their paddock than the control groups. Thus, it was concluded that coadministration of D. flagrans and M. thaumasium was effective in controlling gastrointestinal helminths of adults and young sheep in the semiarid region of northeastern Brazil.

The purpose of this study was to investigate the protective effects of combined treatment of folate and vitamin B12 against alcoholic liver disease. Male Wistar rats weighing about 160 g were divided into four groups: an ethanol group fed an ethanol liquid diet; a control group pair-fed an isoenergetic diet without ethanol; an ethanol and vitamin group fed an ethanol-containing diet that was supplemented with folate (10 mg/kg of body weight per day) and vitamin B12 (0.5 mg/kg of body weight per day); and a control and vitamin group fed an isoenergetic diet without ethanol, which was supplemented with folate (10 mg/kg of body weight per day) and vitamin B12 (0.5 mg/kg of body weight per day). After 16 wk, the plasma folate concentration in the ethanol group was significantly lower than in the other three groups. The plasma homocysteine concentration in the ethanol group was significantly higher than in the other three groups. The hepatic matrix metalloproteinase-2 concentration in the ethanol group was significantly higher than in the control and ethanol/vitamin groups. Furthermore, the plasma homocysteine concentration at the 16th week and the hepatic matrix metalloproteinase-2 concentration showed a significant positive correlation in rats of each group. In addition, pathologic evidence of liver fibrosis was observed only in the ethanol group. Furthermore, hepatic cytochrome 2E1 protein expression in group E increased significantly. These results suggest that combined treatment of folate and vitamin B12 can alleviate alcoholic liver injury that may be related to normalization of plasma homocysteine levels.

Although it is known that lifestyle behaviors of pregnant women are closely related to maternal and fetal health, number of data concerning efficacy of intervention on lifestyle during pregnancy is limited. The purpose of this study is to determine the effect of lifestyle interventions on improving dietary habits and lifestyle behaviors, ensuring gestational weight gain (GWG) within recommended levels and limiting postpartum weight retention (PWR). The study was conducted as a randomized controlled trial in a family health center located in Istanbul, Turkey, between June 2011 and July 2012. The primary outcomes were GWG, and the proportion of pregnant women whose GWG was within the Institute of Medicine (IOM) guidelines. One hundred two pregnant women with gestation ≤12 weeks, age ≥18 years, gravidity ≤2, and who did not intend to lose weight in prepregnancy period were randomly included in this study as intervention (n = 51) and control (n = 51) groups. The study was completed with 45 women for each group. The control group received routine antenatal care. The intervention group was received an individualized lifestyle intervention focusing on healthy lifestyle, diet, exercise, and weight monitoring as four sessions at 12-15, 16-18, 20-24, and 37 weeks gestation. Lifestyle behaviors were evaluated with Health-Promoting Lifestyle Profile-II. Dietary habits were assessed by 3-day dietary recalls, and weight was followed from pregnancy until 6 weeks postpartum. The lifestyle interventions had a significant effect on improving lifestyle behaviors, protein intake, percentage of energy from protein, calcium, magnesium, iron, zinc, and vegetable intakes when adjusted for confounders (p < 0.05). The proportion of women who were within the IOM recommendations was higher in the intervention group (51.1 %) than in the control group (28.9 %) The odds ratio for GWG within IOM was statistically significant between the groups (OR = 0.59, 95 % CI, 0.45-0.72). There were no difference between groups in terms of the other dietary intakes, total GWG, and PWR (p > 0.05). Lifestyle intervention improves the lifestyle behaviors during pregnancy and increases the appropriate GWG for prepregnancy body mass index (BMI), but it has a limited effect in terms of improving dietary habits and has no effect on PWR.

To assess the efficacy and safety of a green tea meal replacement formula product for the treatment of obesity. A 12-week clinical trial was performed, in which 120 (25 male, 95 female) healthy, overweight and obese persons were included ( each of them occupy one-third of the whole population). The green tea formula was provided in the treatment group and normal diet was provided as control. More weight loss was found in the treatment group than the control (6.8 versus 2.3 kg; P <0.001). Also, the treatment group had a greater changes in total cholesterol (185.2 versus 215.2 mg/dl; P=0.011) and low-density lipoprotein cholesterol (106.7 versus 127.6 mg/dl; P<0.005). Among completers only, the treatment group again lost more weight (6.8 kg; n=54 versus 0.8 kg; n =56; P =0.001) and had a greater reduced total body fat mass (7.6%; n=37 versus 0.5%; P=0.005) This green tea meal replacement formula contributes to the lower body weight and reduced low-density lipoprotein cholesterol level.

The aim of this study was to examine the potential effects of valproate (VPA) and oxcarbazepine (OXC) on testicular development in rats. Forty-two Wistar rats were randomly divided into three groups of 14 rats each. Each group received the following via gavage over 90 days: group 1, tap water (control group); group 2, VPA (300mg/kg/day); group 3, OXC (100mg/kg/day). After sacrifice, body, testicular and epididymidis weights were measured. Testes were sampled, fixed and processed, and quantitative morphometric analysis of Sertoli cells, spermatocytes and spermatids was performed in stages II, V and XII by histopathological examination. Immunohistochemical staining was performed to transform growth factor beta 1 (TGF-β1) and p53, and the apoptotic index was assessed using the TUNEL method. Testis and relative testis weights were significantly lower in the VPA group compared to the control group (p<0.05). Spermatogonia, pachytene spermatocyte and round spermatocyte numbers decreased in all stages in both the VPA and OXC groups compared to the control group, though this was not statistically significant (p>0.05). Apoptotic cell counts and p53 immunoreaction were significantly high and TGF-β1 expression was significantly lower in the VPA group compared to that of the control group (p<0.05). In the OXC group, p53 immunoreaction and TGF-β1 expression decreased compared to the control group, but this difference did not attain statistical significance (p>0.05). Our results show that VPA treatment from prepuberty to adulthood significantly negatively affects spermatogenesis, not only by reducing testicular weight, but also by increasing apoptotic death and p53 and decreasing TGF-β1 activation. OXC has a minimal side effect on testicular development. Copyright © 2010 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

Prospects for changing multiple health behaviors conjointly remain controversial. We compared effects on tobacco abstinence and weight gain of adding diet and exercise concurrently or after smoking treatment. Female regular smokers (n=315) randomized to 3 conditions received 16 weeks of behavioral smoking treatment, quit at week 5, and were followed for 9 months after the quit date. Weight management was added to the first 8 weeks for Early Diet (ED), the final 8 weeks for Late Diet (LD), and omitted for Control. Both Diet groups tended to show greater bio-verified abstinence than Control although differences were nonsignificant. Compared to Control, ED initially suppressed weight gain but lost that effect over time, whereas LD initially lacked but gradually acquired a weight suppression effect that stabilized [p = .004]. Behavioral weight control did not undermine smoking cessation and slowed the rate of weight gain when initiated after the smoking quit date, supporting a sequential approach to multiple behavior change.

A 6-month randomized controlled trial to test the efficacy of a lifestyle intervention for weight gain management in schizophrenia

PubMed Central

2013-01-01

Background Patients with schizophrenia have lower longevity than the general population as a consequence of a combination of risk factors connected to the disease, lifestyle and the use of medications, which are related to weight gain. Methods A multicentric, randomized, controlled-trial was conducted to test the efficacy of a 12-week group Lifestyle Wellness Program (LWP). The program consists of a one-hour weekly session to discuss topics like dietary choices, lifestyle, physical activity and self-esteem with patients and their relatives. Patients were randomized into two groups: standard care (SC) and standard care plus intervention (LWP). Primary outcome was defined as the weight and body mass index (BMI). Results 160 patients participated in the study (81 in the intervention group and 79 in the SC group). On an intent to treat analysis, after three months the patients in the intervention group presented a decrease of 0.48 kg (CI 95% -0.65 to 1.13) while the standard care group showed an increase of 0.48 kg (CI 95% 0.13 to 0.83; p=0.055). At six-month follow-up, there was a significant weight decrease of −1.15 kg, (CI 95% -2.11 to 0.19) in the intervention group compared to a weight increase in the standard care group (+0.5 kg, CI 95% -0.42–1.42, p=0.017). Conclusion In conclusion, this was a multicentric randomized clinical trial with a lifestyle intervention for individuals with schizophrenia, where the intervention group maintained weight and presented a tendency to decrease weight after 6 months. It is reasonable to suppose that lifestyle interventions may be important long-term strategies to avoid the tendency of these individuals to increase weight.

To assess the effects of motivational interviewing for obese children and telephone consultation for parents to promote weight loss in obese children. Childhood obesity is a worldwide health problem that leads to serious metabolic and physiological consequences. An effective intervention to manage obesity is essential. Motivational interviewing is designed to resolve ambivalence, enhance intrinsic motivation and promote confidence in a person's ability to make behaviour changes. It has shown promise in the adult obesity literature as effecting positive health behaviour changes. Motivational interviewing has also been proposed as an effective method for improving the weight loss of obese children. A pre-post quasi-experimental design with repeated measures was used. The study was conducted in four primary schools over an 11-month period in 2010-2011. Obese children (n = 185) were screened from 791 school children studying the equivalent to UK grades 5 and 6 and were divided into three groups: motivational interviewing, motivational interviewing+ and a control group. The motivational interviewing group (n = 70) children were provided with motivational interviewing counselling; the motivational interviewing+ group (n = 66) children were provided with motivational interviewing counselling while telephone consultation was provided for their parents; and the control group did not receive any intervention (n = 49). Children in both the motivational interviewing and motivational interviewing+ groups showed significant improvement in their weight-related behaviour and obesity-related anthropometric measures from the baseline to the end of the 14-week intervention, while the control group had significant deterioration in their anthropometric measures. Motivational interviewing appears to be a promising intervention for promoting weight loss in obese children. Motivational interviewing counselling may be extended to obese children of different age groups. This study indicates that motivational interviewing is a useful method for improving behaviour changes in eating, physical activity and weight loss for obese children, suggesting the benefits of such intervention. © 2013 Blackwell Publishing Ltd.

Functional weight-bearing mobilization may improve repair of Achilles tendon rupture (ATR), but the underlying mechanisms and outcome were unknown. We hypothesized that functional weight-bearing mobilization by means of increased metabolism could improve both early and long-term healing. In this prospective randomized controlled trial, patients with acute ATR were randomized to either direct post-operative functional weight-bearing mobilization (n = 27) in an orthosis or to non-weight-bearing (n = 29) plaster cast immobilization. During the first two post-operative weeks, 15°-30° of plantar flexion was allowed and encouraged in the functional weight-bearing mobilization group. At 2 weeks, patients in the non-weight-bearing cast immobilization group received a stiff orthosis, while the functional weight-bearing mobilization group continued with increased range of motion. At 6 weeks, all patients discontinued immobilization. At 2 weeks, healing metabolites and markers of procollagen type I (PINP) and III (PIIINP) were examined using microdialysis. At 6 and 12 months, functional outcome using heel-rise test was assessed. Healing tendons of both groups exhibited increased levels of metabolites glutamate, lactate, pyruvate, and of PIIINP (all p < 0.05). Patients in functional weight-bearing mobilization group demonstrated significantly higher concentrations of glutamate compared to the non-weight-bearing cast immobilization group (p = 0.045).The upregulated glutamate levels were significantly correlated with the concentrations of PINP (r = 0.5, p = 0.002) as well as with improved functional outcome at 6 months (r = 0.4; p = 0.014). Heel-rise tests at 6 and 12 months did not display any differences between the two groups. Functional weight-bearing mobilization enhanced the early healing response of ATR. In addition, early ankle range of motion was improved without the risk of Achilles tendon elongation and without altering long-term functional outcome. The relationship between functional weight-bearing mobilization-induced upregulation of glutamate and enhanced healing suggests novel opportunities to optimize post-operative rehabilitation.

Weight bearing after total hip arthroplasty is postponed in order to prevent early loosening, but this negatively affects the rehabilitation programme. For the force transfer characteristics of thrust plate prosthesis (TPP), a new type of hip prosthesis used without cement is similar to the normal hip. We evaluated the possibilities of early weight bearing after TPP by comparing early partial with early full weight bearing. Randomized controlled study. Department of orthopaedics and traumatology in a university hospital. Sixty hips of 51 patients who underwent total hip arthroplasty with TPP were randomly assigned into two groups. Both groups received accelerated rehabilitation programmes: group 1 with early partial weight bearing and group 2 with early full weight bearing. Patients were evaluated by a blind observer preoperatively, at three months after surgery by clinical (measurement of range of hip motion (universal goniometry), muscle strength (Manual Muscle Test), functional test (6-minute walk test), hip function (Harris Hip Scoring System)) and radiographical parameters and one year after surgery by clinical (Harris Hip Scoring System) and radiographical parameters. Group 2 performed transfer activities earlier, had more walking distance at the time of discharge and shorter hospital stay than group 1. At three months, Harris Hip Score, muscle strength, 6-minute walk test, and duration of crutch use were significantly (p < 0.05) in favour of group 2. None of the patients in either group showed signs of loosening one year after the operation. These results suggest that patients with TPP can tolerate an accelerated rehabilitation programme with early weight bearing and will gain the goals of rehabilitation earlier.

In Korea, obesity is more prevalent among men and lower socioeconomic groups. To explain this obesity disparity, we compared weight perception and weight control behavior across gender and socioeconomic status (SES). We analyzed data from 16,260 participants aged 20 years or older in a nationally representative cross-sectional survey. SES indicators included education and income levels. Weight under-perception was defined when participants considered themselves lighter than their measured BMI status. Either no active or inappropriate weight control (i.e., trying to gain weight in obese individuals) was considered to be unhealthy patterns. Multivariate prevalence ratios were calculated using log-binomial regressions. Men had a higher prevalence of weight under-perception (24.5 vs. 11.9%) and unhealthy patterns of weight control behavior (57 vs. 40%) than women. Low education level was associated with weight under-perception (ptrend = 0.022 in men, ptrend < 0.001 in women). Both education and income levels were significantly associated with patterns of weight control behavior (for education: ptrend < 0.001 in men and women; for income: ptrend = 0.047 in men, ptrend < 0.001 in women). Weight perception and weight control behavior significantly varied by gender and SES. Public actions should be directed toward improving perception and behavior of high-risk populations.

Beneficial effects of green tea polyphenols (GTP) against obesity have been reported, however, the mechanism of this protection is not clear. Therefore, the objective of this study was to identify GTP-targeted genes in obesity using the high-fat-diet-induced obese rat model. A total of three groups (n = 12/group) of Sprague Dawley (SD) female rats were tested, including the control group (rats fed with low-fat diet), the HF group (rats fed with high-fat diet), and the HF+GTP group (rats fed with high-fat diet and GTP in drinking water). The HF group increased body weight as compared to the control group. Supplementation of GTP in the drinking water in the HF+GTP group reduced body weight as compared to the HF group. RNA from liver samples was extracted for gene expression analysis. A total of eighty-four genes related to obesity were analyzed using PCR array. Compared to the rats in the control group, the rats in the HF group had the expression levels of 12 genes with significant changes, including 3 orexigenic genes (Agrp, Ghrl, and Nr3c1); 7 anorectic genes (Apoa4, Cntf, Ghr, IL-1β, Ins1, Lepr, and Sort); and 2 genes that relate to energy expenditure (Adcyap1r1 and Adrb1). Intriguingly, the HF+GTP group restored the expression levels of these genes in the high-fat-induced obese rats. The protein expression levels of IL-1β and IL-6 in the serum samples from the control, HF, and HF+GTP groups confirmed the results of gene expression. Furthermore, the protein expression levels of superoxide dismutase-1 (SOD1) and catechol-O-methyltransferase (COMT) also showed GTP-regulated protective changes in this obese rat model. Collectively, this study revealed the beneficial effects of GTP on body weight via regulating obesity-related genes, anti-inflammation, anti-oxidant capacity, and estrogen-related actions in high-fat-induced obese rats.

IMPORTANCE Rapid infant weight gain is associated with later obesity, but interventions to prevent rapid infant growth and reduce risk for overweight status in infancy are lacking. OBJECTIVE To examine the effect of a responsive parenting (RP) intervention on infant weight gain between birth and 28 weeks and overweight status at age 1 year. DESIGN, SETTING, AND PARTICIPANTS The Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) study is an ongoing randomized clinical trial comparing an RP intervention designed to prevent childhood obesity with a safety control. The study includes primiparous mother-newborn dyads (n = 291) and was conducted at the Penn State Milton S. Hershey Medical Center, Hershey, Pennsylvania, in addition to home visits. Enrollment was initiated in January 2012, and evaluable population analyses for this study were conducted between April 2015 and November 2015. INTERVENTIONS At 2 weeks post partum, initial intervention materials appropriate to the assigned treatment group were mailed to the participant’s home. Research nurses conducted home visits at 3 weeks, 16 weeks, 28 weeks, and 40 weeks, and a research center visit occurred at 1 year. The Intervention Nurses Start Infants Growing on Healthy Trajectories curriculum included messages about infant feeding, sleep hygiene, active social play, emotion regulation, and growth record education. The control group received a developmentally appropriate home safety intervention also delivered by nurse home visitors. MAIN OUTCOMES AND MEASURES Conditional weight gain from birth to 28 weeks was calculated. General linear models examined intervention effect on conditional weight gain. The intervention’s effect on infant weight-for-length percentiles was tested using analysis of variance. Logistic regression compared the odds of overweight status (weight for length ≥95th percentile) at 1 year as a function of conditional weight gain. RESULTS Of the mothers included in the study, 246 were white (88%), 260 were non-Hispanic (93%), 210 were married (75%), and 201 were working full time (72%) at time of enrollment. The mean conditional weight gain score was lower among infants in the RP group compared with the control group (−0.18; 95% CI, −0.36 to −0.001), reflecting that the RP infants gained weight more slowly than control group infants (0.18; 95% CI, 0.02–0.34); this effect did not differ by feeding mode (predominantly fed breast milk or not). Infants in the RP group also had lower mean weight-for-length percentiles at 1 year than infants in the control group (57.5%; 95% CI, 52.56%–62.37% vs 64.4%; 95% CI, 59.94%–69.26%; P = .04) and were less likely to be overweight at age 1 year (5.5% vs 12.7%; P = .05). CONCLUSIONS AND RELEVANCE An RP intervention is associated with reduced rapid weight gain during the first 6 months after birth and overweight status at age 1 year.

Obstetric and neonatal outcomes of assisted reproduction and control singletons were evaluated after taking into account treatment characteristics and infertility background. The elective single embryo transfer (eSET) group (n = 45) was compared with the compulsory single embryo transfer (cSET; n = 52), double embryo transfer (DET; n = 227) and control (n = 304) groups. Infertility-related prognostic factors for neonatal outcomes were also analysed. Data were collected with structured questionnaires at gestational week 20 and 8 weeks after delivery. Spontaneous onset of delivery was more typical of the eSET group than of cSET and DET groups (68.9 versus 52.0%, P = 0.02). Mean (+/-SD) gestation at birth (39.3 +/- 1.6 weeks) and mean birth weight (3,470 +/- 505 g) of eSET singletons were comparable with other assisted reproduction groups, but gestational duration was lower than in the eSET group than in the control group (39.9 +/- 1.4; P < 0.05). However, numbers of preterm births and low birth weight infants were similar between groups. History of induced abortion increased risk of preterm birth (OR 4.5 and 95% CI 1.2-17.1) in assisted reproduction singletons. A small though clinically unimportant difference in gestational age at birth and birth weight between assisted reproduction and control singletons was found regardless of the number of embryos transferred.

To examine whether premature infants receiving the maternally administered H-HOPE (Hospital to Home Transition-Optimizing Premature Infant's Environment) intervention had more rapid weight gain and growth, improved feeding progression and reduced length of hospital stay, compared with controls. Premature infants born at 29-34 weeks gestational age and their mothers with at least two social-environmental risk factors were randomly assigned to H-HOPE intervention (n=88) or an attention control (n=94) groups. H-HOPE consists of a 15-min multisensory intervention (Auditory, Tactile, Visual and Vestibular stimuli) performed twice daily prior to feeding plus maternal participatory guidance on preterm infant behavioral cues. H-HOPE group infants gained weight more rapidly over time than infants in the control group and grew in length more rapidly than control infants, especially during the latter part of the hospital stay. For healthy preterm infants, the H-HOPE intervention appears to improve weight gain and length over time from birth to hospital discharge.

The ameliorative effect of ascorbic acid (AA) on live weight following transportation is vital in animal husbandry. This study investigated the influence of AA on live weight, rectal temperature (rt), and oxidative status of transport stressed goats in a hot humid tropical environment. Twenty-four goats were divided into four groups, A, B, C and D of six animals each. Group A were administered AA 100 mg/kg intramuscularly 30 min prior to 3.5 h transportation. Group B was administered AA following transportation. Group C were transported but not administered AA as positive controls while group D were not transported but were administered normal saline as negative controls. Live weight, rt and blood samples were collected before, immediately post-transport (pt), 24 h, 3 days, 7 days and 10 days pt. Plasma was used for malondialdehyde (MDA) analysis while hemolysates were used for superoxide dismutase (SOD) analysis. There was minimal live weight loss in group A compared to groups B and C. Group A recorded reduced MDA activities and increased SOD activities compared to groups B and C which recorded significantly high MDA activities. This study revealed that AA administration ameliorated the stress responses induced by transportation in animals in hot humid tropical environments. The administration of AA to goats prior to transportation could ameliorate stress and enhance productivity. © 2014 Japanese Society of Animal Science.

The effects of low-molecular-weight-chitosan (LMWC) on chronic renal failure (CRF) rats induced by adenine were investigated in vivo and in vitro. Chitosan were hydrolyzed using chitosanase at pH 6-7 and 37° for 24 h to obtain LMWC. In vitro, the effect of LMWC on the proliferation of renal tubular epithelial cells (RTEC) showed that it had no cytotoxic effect and could promote cell growth. For the in vivo experiment, chronic renal failure rats induced by adenine were randomly divided into control group, Niaoduqing group, and high-, medium- and low-dose LMWC groups. For each group, we detected serum creatinine (SCR), blood urea nitrogen (BUN), and total superoxide dismutase (T-SOD), glutathione oxidase (GSH-Px) activities of renal tissue, and obtained the ratio of kidney weight/body weight, pathological changes of kidney. The levels of serum SCR, BUN were higher in the adenine-induced rats than those in the control group, indicating that the rat chronic renal failure model worked successfully. The results after treatment showed that LMWC could reduce the SCR and BUN levels and enhance the activities/levels of T-SOD and GSH-PX in kidney compared to control group. Histopathological examination revealed that adenine-induced renal alterations were restored by LMWC at three tested dosages, especially at the low dosage of 100 mg kg-1 d-1.

We conducted a meta-analysis of randomized controlled trials to examine the association of mobile phone intervention with net change in weight-related measures among overweight and obese adults. We searched electronic databases and conducted a bibliography review to identify articles published between the inception date of each database and March 27, 2014. Fourteen trials (including 1,337 participants in total) that met the eligibility criteria were included. Two investigators independently abstracted information on study characteristics and study outcomes. Net change estimates comparing the intervention group with the control group were pooled across trials using random-effects models. Compared with the control group, mobile phone intervention was associated with significant changes in body weight and body mass index (weight (kg)/height (m)2) of −1.44 kg (95% confidence interval (CI): −2.12, −0.76) and −0.24 units (95% CI: −0.40, −0.08), respectively. Subgroup analyses revealed that the associations were consistent across study-duration and intervention-type subgroups. For example, net body weight changes were −0.92 kg (95% CI: −1.58, −0.25) and −1.85 kg (95% CI: −2.99, −0.71) in trials of shorter (<6 months) and longer (≥6 months) duration, respectively. These findings provide evidence that mobile phone intervention may be a useful tool for promoting weight loss among overweight and obese adults. PMID:25673817

The aim of the following study is to evaluate the effect of life-style modification on postmenopausal (PM) overweight and obese Indian women in a randomized controlled 24 week study. Two groups were formed Group I (n = 30) was designated as intervention (dietary and exercise group) and Group II (n = 24) served as control. Comparison of weight, waist circumference (WC) and body mass index (BMI) were made and compared among two groups at 4, 8, 16 and 24 weeks. Mean age at menopause was 48.35 years versus 49.65 years; mean number of menopausal symptoms were 5.70 ± 1.76 versus 5.10 ± 1.56 and mean duration since menopause was 2.70 versus 2.90 years in Groups I and II respectively. When the effect of Group I and control on weight was compared at 4, 8, 16 and 24 weeks, there was no significant difference between them up to 8 week. At 8 weeks Group I caused a significant decrease in weight (P ≤ 0.05) when compared with control arm and which continued throughout the study period (P < 0.05) at both 16 and 24 weeks. Group I produced a significant reduction in WC from 8 weeks onwards up to 24 weeks (P ≤ 0.05). BMI was statistically significant in Group I and the effect started at 4(th) week (P ≤ 0.05) and the differences in BMI reduction were highly significant at 16(th) and 24(th) weeks (P ≤ 0.001). The results of the present study strongly recommend the life-style management to be incorporated in daily style of postmenopausal women under controlled supervision.

Obesity remains a major public health challenge, demanding cost-effective and scalable weight management programs. Delivering key treatment components via mobile technology offers a potential way to reduce expensive in-person contact, thereby lowering the cost and burden of intensive weight loss programs. The ENGAGED study is a theory-guided, randomized controlled trial designed to examine the feasibility and efficacy of an abbreviated smartphone-supported weight loss program. Ninety-six obese adults (BMI 30-39.9 kg/m2) will be randomized to one of three treatment conditions: (1) standard behavioral weight loss (STND), (2) technology-supported behavioral weight loss (TECH); or (3) self-guided behavioral weight loss (SELF). All groups will aim to achieve a 7% weight loss goal by reducing calorie and fat intake and progressively increasing moderate intensity physical activity to 175 minutes/week. STND and TECH will attend 8 group sessions and receive regular coaching calls during the first 6 months of the intervention; SELF will receive the Group Lifestyle Balance Program DVD's and will not receive coaching calls. During months 1-6, TECH will use a specially designed smartphone application to monitor dietary intake, body weight, and objectively measured physical activity (obtained from a Blue-tooth enabled accelerometer). STND and SELF will self-monitor on paper diaries. Linear mixed modeling will be used to examine group differences on weight loss at months 3, 6, and 12. Self-monitoring adherence and diet and activity goal attainment will be tested as mediators. ENGAGED is an innovative weight loss intervention that integrates theory with emerging mobile technologies. We hypothesize that TECH, as compared to STND and SELF, will result in greater weight loss by virtue of improved behavioral adherence and goal achievement. NCT01051713.

To study effects of 50 Hz 1.8 mT sinusoidal electromagnetic fields (SEMFs) on bone mineral density (BMD) in SD rats. Thirty SD rats weighted(110±10) and aged 1 month were randomly divided into control group and electromagnetic field group, 15 in each group. Normal control group of 50 Hz 0 mT density and sinusoidal electromagnetic field group of 50 Hz 1.8 mT were performed respectively with 1.5 h/d and weighted weight once a week, and observed food-intake. Rats were anesthesia by intraperitoneal injection and dual energy X-ray absorptiometry were used to detect bone density of whole body, and detected bone density of femur and vertebral body. Osteocalcin and tartrate-resistant acid phosphatase 5b were detected by ELSA; weighted liver, kidney and uterus to calculate purtenance index, then detected pathologic results by HE. Compared with control group, there was no significant change in weight every week, food-intake every day; no obvious change of bone density of whole body at 2 and 4 weeks, however bone density of whole body, bone density of excised femur and vertebra were increased at 6 weeks. Expression of OC was increased, and TRACP 5b expression was decreased. No change of HE has been observed in liver, kidney and uterus and organic index. 50 Hz 1.8 mT sinusoidal electromagnetic fields could improve bone formation to decrease relevant factors of bone absorbs, to improve peak bone density of young rats, in further provide a basis for clinical research electromagnetic fields preventing osteoporosis foundation.

A blinded, randomized, controlled, multi-centric field study was conducted on French dairy farms (n = 9) to evaluate the long term efficacy of metaphylactic, single oral treatments with either 1 mg/kg body weight (BW) of diclazuril (Vecoxan®), or 15 mg/kg BW of toltrazuril (Baycox®) against natural infections with Eimeria zuernii and/or Eimeria bovis, compared to untreated control animals. A total of 199 calves from nine commercial farms aged between 21 and 55 days old at the start of study were included and randomly allocated to one of three groups. Calves on all farms were observed for a period of 78 days post treatment, using both parasitological (oocyst excretion), and clinical parameters (faecal score and body weight). The assessment of efficacy was based on both control of oocyst excretion, and on the average daily weight gains throughout the study. During the whole study period, the mean number of days with diarrhoea (≥ 2) was similar (0.7 days) between treated groups. Excretion in the untreated group peaked at 21 days after treatment. In both the diclazuril and toltrazuril-treated groups, mean oocyst excretion decreased dramatically in the five days following treatment. Thereafter, particularly towards the end of the study period, oocyst counts and percentage levels of E. zuernii were highest in the toltrazuril-treated group. In pooled data from all trial sites, the average daily weight gain was significantly (p = 0.01) higher (+ 0.057 kg/day) in the diclazuril group when compared to the toltrazuril group, and the average body weight gain of the diclazuril treated group was 4.4 kg higher than the toltrazuril group. On eight of the nine trial sites, the average daily gain was greater in the diclazuril group than in the toltrazuril group. This study demonstrates that, over an extended observation period of 78 days, metaphylactic treatment with both diclazuril and toltrazuril reduces the impact of coccidiosis, but greater performance benefits based on average daily weight gains, were achieved following the use of diclazuril.

The ability of chemists to design and synthesize pi-conjugated organic polymers with precise control remains the key to technological breakthroughs for using polymer materials in electronic and photonic devices. In this communication, the controlled chain-growth polymerization of regioregular poly(3-hexylthiophene) (P3HT) from an external initiator using 1,3-bis(diphenylphosphino)propane (dppp) as a catalyst ligand is reported. The complexes cis-chloro(phenyl)(dppp)nickel(II) and cis-chloro(o-tolyl)(dppp)nickel(II) were synthesized and characterized by (31)P NMR spectroscopy. These complexes served as initiators in the polymerization of 2-bromo-5-chloromagnesio-3-hexylthiophene in THF at room temperature, affording fully regioregular P3HT with controlled molecular weights and narrow molecular weight distributions, as demonstrated by gel-permeation chromatography and (1)H NMR spectroscopy. MALDI-TOF mass spectrometry revealed that the polymers had almost complete incorporation of the initiating aryl group, and when the aryl group was o-tolyl, only Tol/H end groups were observed. Although external initiators have been used previously with a PPh(3) ligand, that methodology led to polymers with broad molecular weight distributions. This is the first example in which complete control over the externally initiated P3HT polymerization has been achieved.

Alternate-day fasting has become increasingly popular, yet, to date, no long-term randomized clinical trials have evaluated its efficacy. To compare the effects of alternate-day fasting vs daily calorie restriction on weight loss, weight maintenance, and risk indicators for cardiovascular disease. A single-center randomized clinical trial of obese adults (18 to 64 years of age; mean body mass index, 34) was conducted between October 1, 2011, and January 15, 2015, at an academic institution in Chicago, Illinois. Participants were randomized to 1 of 3 groups for 1 year: alternate-day fasting (25% of energy needs on fast days; 125% of energy needs on alternating "feast days"), calorie restriction (75% of energy needs every day), or a no-intervention control. The trial involved a 6-month weight-loss phase followed by a 6-month weight-maintenance phase. The primary outcome was change in body weight. Secondary outcomes were adherence to the dietary intervention and risk indicators for cardiovascular disease. Among the 100 participants (86 women and 14 men; mean [SD] age, 44 [11] years), the dropout rate was highest in the alternate-day fasting group (13 of 34 [38%]), vs the daily calorie restriction group (10 of 35 [29%]) and control group (8 of 31 [26%]). Mean weight loss was similar for participants in the alternate-day fasting group and those in the daily calorie restriction group at month 6 (-6.8% [95% CI, -9.1% to -4.5%] vs -6.8% [95% CI, -9.1% to -4.6%]) and month 12 (-6.0% [95% CI, -8.5% to -3.6%] vs -5.3% [95% CI, -7.6% to -3.0%]) relative to those in the control group. Participants in the alternate-day fasting group ate more than prescribed on fast days, and less than prescribed on feast days, while those in the daily calorie restriction group generally met their prescribed energy goals. There were no significant differences between the intervention groups in blood pressure, heart rate, triglycerides, fasting glucose, fasting insulin, insulin resistance, C-reactive protein, or homocysteine concentrations at month 6 or 12. Mean high-density lipoprotein cholesterol levels at month 6 significantly increased among the participants in the alternate-day fasting group (6.2 mg/dL [95% CI, 0.1-12.4 mg/dL]), but not at month 12 (1.0 mg/dL [95% CI, -5.9 to 7.8 mg/dL]), relative to those in the daily calorie restriction group. Mean low-density lipoprotein cholesterol levels were significantly elevated by month 12 among the participants in the alternate-day fasting group (11.5 mg/dL [95% CI, 1.9-21.1 mg/dL]) compared with those in the daily calorie restriction group. Alternate-day fasting did not produce superior adherence, weight loss, weight maintenance, or cardioprotection vs daily calorie restriction. clinicaltrials.gov Identifier: NCT00960505.

Weight reduction improves glycemic control in obese men with glycated hemoglobin (HbA1c) of 5.6-6.4%, suggesting that it can prevent the development of diabetes in these patients. The aim of the present study was to quantify the amount of weight reduction necessary for minimization of diabetes risk in Japanese men with visceral fat accumulation. The study participants were 482 men with an estimated visceral fat area of ≥100 cm(2), HbA1c of 5.6-6.4%, fasting plasma glucose (FPG) of <126 mg/dL or casual plasma glucose <200 mg/dL. They were divided into two groups based on weight change at the end of the 3-year follow-up period (weight gain and weight loss groups). The weight loss group was classified into quartile subgroups (lowest group, 0 to <1.2%: second lowest group, ≥1.2 to <2.5%: second highest group, ≥2.5 to <4.3%: highest group, ≥4.3% weight loss). The development of diabetes at the end-point represented a rise in HbA1c to ≥6.5% or FPG ≥126 mg/dL, or casual plasma glucose ≥200 mg/dL. The cumulative incidence of diabetes at the end of the 3-year follow-up period was 16.2% in the weight gain group and 10.1% in the weight loss group (P not significant). The incidence of diabetes was significantly lower in the highest weight loss group (3.1%), but not in the second highest, the second lowest and the lowest weight loss groups (9.7, 10.1 and 18.3%), compared with the weight gain group. Minimization of the risk of diabetes in Japanese men with visceral fat accumulation requires a minimum of 4-5% weight loss in those with HbA1c of 5.6-6.4%.

Objective To evaluate the effect of Meperidine, commonly administered for labor analgesia, on newborn weight and peripartum breastfeeding during two months after delivery. Materials and methods This pilot cohort study was conducted between October 2010 and October 2011 at the Women Hospital of the Tehran University of Medical Sciences. In this study, we examined the effects of meperidine on breastfeeding and neonatal weight. A total number of 184 full term pregnant women, planned to deliver at this center (normal vaginally delivery or cesarean), participated in this study. The study group included the women who received meperidine in peripartum time to be compared with a control group who did not receive any opioid. Meperidine was administrated to them based on their peripartum breastfeeding behaviour and baby weight, two month after delivery. Results Of the 184 woman recruited to the trial, 38 women had normal vaginal delivery and 146 had ccesarean. Within the first two-month, 4% of mothers in control group and 11% of meperidine group used formula. However, this differences were not statistically significant (p value= 0.07). Furthermore, baby weight distribution was not statistically different between two groups. Conclusion The inhibitory effect of using Meperidine on peripartum breastfeeding and weight of newborn in the first two months was not statistically significant in this study. More research is needed to clarify the association between meperidine and peripartum breastfeeding. PMID:24971099

Comparison of the effects of one year treatment with sibutramine compared to placebo on insulin resistance parameters, body weight, glycemic control, and lipid profile, in type 2 diabetic patients. Two hundred and forty-six patients with uncontrolled type 2 diabetes mellitus in therapy with different oral hypoglycemic agents or insulin were enrolled in this study and randomised to take sibutramine 10 mg or placebo for one year. We evaluated at baseline, and after 3, 6, 9, and 12 months these parameters: homeostasis model assessment insulin resistance index (HOMA-IR), retinol binding protein-4 (RBP-4), resistin, visfatin, and high sensitivity-C reactive protein (Hs-CRP), body weight, body mass index (BMI), glycated hemoglobin (HbA(₁c)), fasting plasma glucose (FPG), post-prandial plasma glucose (PPG), fasting plasma insulin (FPI), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), and triglycerides (T(g)). A faster decrease of HOMA-IR, resistin, and RBP-4 was recorded with sibutramine compared to the control group. We observed a significant decrease of Hs-CRP in both groups, and a faster improvement of HbA(₁c), FPG and PPG with sibutramine compared to the control group; furthermore we recorded a decrease of FPI, TC, LDL-C, body weight, and BMI in the sibutramine group, but not in the control group. Sibutramine gave a faster improvement of insulin resistance parameters and glycemic control compared to placebo; furthermore sibutramine gave also an improvement of lipid profile, and body weight.

The management of obesity is complex and it must be multidisciplinary. Behavioral treatments for control of childhood obesity are based on family; these have a high degree of efficiency. It has been argued that when children and their parents are the main goal of the changes of behavior as a group, results of weight loss generally are better. The objective of this study was to establish the effect of an intervention based on family to reduce weight in students with overweight or obesity. Quasi-experimental study in schoolchildren from 6 to 12 years of age, from a family medicine unit in Ciudad Obregón, Sonora, México. The intervention group corresponded to 30 schoolchildren with overweight or obesity, and one or both of their parents with overweight or obesity; the control group included 30 schoolchildren with overweight or obesity, and normal-weight parents. Weight, height and body mass index (BMI) were measured at baseline, monthly, and at the end of the study. Student t test was used to contrast quantitative variables using the SPSS v.15 program. There were differences in weight, but not in BMI, probably due to the effect of size. Compared with the control group, a higher proportion of schoolchildren showed an improvement with regard to nutritional status. The family intervention is basic for the treatment of overweight and obesity in schoolchildren.

To identify risk factors for adverse pregnancy outcome in women with inflammatory bowel disease (IBD) and to assess the effect of maternal pre-pregnancy weight and weight gain during pregnancy on pregnancy outcome. A retrospective, matched control study of all gravid women with IBD treated in a single tertiary center. Data were compared with healthy controls matched to by age, parity and pre-pregnancy BMI in a 3:1 ratio. Overall, 300 women were enrolled, 75 women in the study group (28 with ulcerative colitis and 47 with Crohn's disease) and 225 in the control group. The rates of preterm delivery and small for gestational age were higher in the study group (13.3 vs. 5.3% p = 0.02 and 6.7 vs. 0.9%, p = 0.004). The rate of cesarean section (36 vs. 19.1%; p = 0.002), NICU admission (10.7 vs. 4.0%, p = 0.03) and low 5-Min Apgar (4.0 vs. 0.4%, p = 0.02) were increased in the study group. Disease activity within 3 months of conception [OR 8.4 (1.3-16.3)] and maternal weight gain of less than 12 kg. [OR 3.6 (1.1-12.2)] were associated with adverse pregnancy outcome. Active disease at conception and inappropriate weight gain during pregnancy are associated with increased adverse pregnancy outcome in patients with IBD.

The aims of this work were to determine whether game-based constraint-induced movement therapy (CIMT) is effective at improving balance ability in patients with stroke, and to provide clinical knowledge of game-based training that allows application of CIMT to the lower extremities. Thirty-six patients with chronic stroke were randomly assigned to game-based CIMT (n = 12), general game-based training (n = 12), and conventional (n = 12) groups. All interventions were conducted 3 times a week for 4 weeks. The static balance control and weight-bearing symmetry were assessed, and the Functional Reach Test (FRT), modified Functional Reach Test (mFRT), and Timed Up and Go (TUG) test were performed to evaluate balance ability. All 3 groups showed significant improvement in anterior-posterior axis (AP-axis) distance, sway area, weight-bearing symmetry, FRT, mFRT, and TUG test after the intervention (P < 0.05). Post hoc analysis revealed significant differences in AP-axis, and sway area, weight-bearing symmetry of the game-based CIMT group compared with the other group (P < 0.05). Although the general game-based training and the game-based CIMT both improved on static and dynamic balance ability, game-based CIMT had a larger effect on static balance control, weight-bearing symmetry, and side-to-side weight shift.

The aim of the study was to analyse body composition of preterm infants fed with either breast milk or formula compared to a control group of full-term newborns. Fifty-three newborns were enrolled: a group of 34 very low birth weight (VLBW) preterm newborns subdivided into a formula-fed (n = 23; group A) and breast milk-fed (n = 11; group B) group, and a control group of 19 full-term infants (group C). Their body composition was assessed by a bioelectrical impedance analysis (BIA) either at the estimated time of birth in the VLBW group or during the 1st week of life in the full-term group. There was no difference in body weight or length between any of the three studied groups. However, we discovered that fat free mass (% FFM) was lower (83.5% vs. 85.5%; p < 0.01), while fat mass (% FM) was higher (16.4% vs.14.5%; p < 0.01) in group A compared to full-term newborns. There were no such differences in FFM (84.3% vs. 85.5%; p = 0.13) or FM (15.7% vs. 14.5%; p = 0.13) between group B and control. To sum up, the VLBW infants fed with breast milk shared similar body composition with the full-term infants, while the formula-fed VLBW developed higher amounts of adipose tissue and lower amounts of fat-free mass. This is the first study to expose differences in fat tissue content attributed to type of provided nutrition, which has become significant as early as estimated time of birth despite the comparable weight.

To assess the association of anthropometric measurements with neonatal complications in macrosomic newborns of non-diabetic mothers. Retrospective cohort study. All liveborn, singleton, full term newborns with birth weight ≥4000 g born to non-diabetic mothers at a tertiary medical centre in 1995-2005 (n=2766, study group) were matched to the next born, healthy, full term infant with a birth weight of 3000-4000 g (control group). Exclusion criteria were multiple birth, congenital infection, major malformations and pregnancy complications. Data collection by file review. Complication rates were compared between study and control groups and between symmetric and asymmetric macrosomic newborns, defined by weight/length ratio (WLR), Body Mass Index and Ponderal Index. The 2766 non-diabetic macrosomic infants identified were matched to 2766 control infants. The macrosomic group had higher rates of hypoglycaemia (1.2% vs 0.5%, p=0.008), transient tachypnoea of the newborn (1.5% vs 0.5%, p<0.001), hyperthermia (0.6% vs 0.1%, p=0.012), and birth trauma (2% vs 0.7%, p<0.001), with no cases of symptomatic polycythaemia, and only one case of hypoglycaemia. Hypoglycaemia was positively associated with birth weight. It was significantly higher in the asymmetric than the symmetric macrosomic newborns, defined by WLR (1.7% vs 0.3%, p<0.001). Macrosomic infants of non-diabetic mothers are at increased risk of neonatal complications. However, routine measurements of haematocrit and calcium may not be necessary. Symmetric macrosomic infants (by WLR) have a similar rate of hypoglycaemia as normal-weight infants. Thus, repeat glucose measurements in symmetric macrosomic infants are not justified.

Weight loss is recommended for overweight or obese patients with type 2 diabetes on the basis of short-term studies, but long-term effects on cardiovascular disease remain unknown. We examined whether an intensive lifestyle intervention for weight loss would decrease cardiovascular morbidity and mortality among such patients. In 16 study centers in the United States, we randomly assigned 5145 overweight or obese patients with type 2 diabetes to participate in an intensive lifestyle intervention that promoted weight loss through decreased caloric intake and increased physical activity (intervention group) or to receive diabetes support and education (control group). The primary outcome was a composite of death from cardiovascular causes, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for angina during a maximum follow-up of 13.5 years. The trial was stopped early on the basis of a futility analysis when the median follow-up was 9.6 years. Weight loss was greater in the intervention group than in the control group throughout the study (8.6% vs. 0.7% at 1 year; 6.0% vs. 3.5% at study end). The intensive lifestyle intervention also produced greater reductions in glycated hemoglobin and greater initial improvements in fitness and all cardiovascular risk factors, except for low-density-lipoprotein cholesterol levels. The primary outcome occurred in 403 patients in the intervention group and in 418 in the control group (1.83 and 1.92 events per 100 person-years, respectively; hazard ratio in the intervention group, 0.95; 95% confidence interval, 0.83 to 1.09; P=0.51). An intensive lifestyle intervention focusing on weight loss did not reduce the rate of cardiovascular events in overweight or obese adults with type 2 diabetes.

Growth hormone deficiency (GHD) patients have lower weight, height, bone age, insulin-like growth factor 1 (IGF-1) levels, GH levels, fat metabolism and skeletal growth. The association of leptin with GHD characteristics and the effect of gene variants of leptin on GHD are unknown. Our aim was to examine the association of circulating leptin levels and common genetic variants in leptin (LEP) and leptin receptor (LEPR) genes with anthropometric measures, circulating hormone concentrations and GHD. A case control study of 125 GHD cases and 159 control subjects were characterized for bone age, body mass index (BMI), height, weight, leptin, IGF-1, GH and their genotype at the leptin promoter G-2548A, and LEPR variants, K109R and Q223R, at Chung Shan Medical University Hospital. Leptin levels were significantly associated with lower bone age, weight and BMI in GHD patients. Leptin levels were also significantly associated with reduced IGF-1 levels in girls but not boys in both groups. The frequency of LEPR223 [A/G or A/A] genotype was significantly higher than the LEPR223 G/G genotype in the GHD group. The LEPR223 [A/G or A/A] genotype was significantly associated with increased weight and BMI in the control group, but not in the GHD group. In conclusion, the GHD group carried a significantly higher frequency of the LEPR [G/A or A/A] genotype and of the A allele (LEPR223R). The LEPR223R polymorphism affected weight and BMI in control, but not in GHD patients, suggesting that the effect of LEPR223 [A/G or A/A] genotype was counteracted by other factor(s) in GHD patients.

Two kinds of oils (i) Polyunsaturated fatty acids (PUFA) rich Safflower oil, and (ii) Medium chain triglyceride (MCT) rich Coconut oil were added to the feeds of 46 very low birthweight (VLBW) babies to see if such a supplementation is capable of enhancing their weight gain. Twenty two well matched babies who received no fortification served as controls. The oil fortification raised the energy density of the feeds from approximately 67 kcal/dl to 79 kcal/dl. Feed volumes were restricted to a maximum of 200 ml/kg/day. The mean weight gain was highest and significantly higher than the controls in the Coconut oil group (19.47 +/- 8.67 g/day or 13.91 g/day). Increase in the triceps skinfold thickness and serum triglycerides were also correspondingly higher in this group. The lead in the weight gain in this group continued in the follow up period (corrected age 3 months). As against this, higher weight gain in Safflower oil group (13.26 +/- 6.58 g/day) as compared to the controls (11.59 +/- 5.33 g/day), failed to reach statistically significant proportions, probably because of increased statistically significant proportions, probably because of increased steatorrhea (stool fat 4+ in 50% of the samples tested). The differences in the two oil groups are presumably because of better absorption of MCT rich coconut oil. However, individual variations in weight gain amongst the babies were wide so that some control babies had higher growth rates than oil fortified ones. The technique of oil fortification is fraught with dangers of intolerance, contamination and aspiration. Long term effects of such supplementation are largely unknown.(ABSTRACT TRUNCATED AT 250 WORDS)

BACKGROUND Behavioural counselling with intensive follow-up for obesity is effective, but in resource-constrained primary care settings briefer approaches are needed. OBJECTIVES To estimate the clinical effectiveness and cost-effectiveness of an internet-based behavioural intervention with regular face-to-face or remote support in primary care, compared with brief advice. DESIGN Individually randomised three-arm parallel trial with health economic evaluation and nested qualitative interviews. SETTING Primary care general practices in the UK. PARTICIPANTS Patients with a body mass index of ≥ 30 kg/m(2) (or ≥ 28 kg/m(2) with risk factors) identified from general practice records, recruited by postal invitation. INTERVENTIONS Positive Online Weight Reduction (POWeR+) is a 24-session, web-based weight management intervention completed over 6 months. Following online registration, the website randomly allocated participants using computer-generated random numbers to (1) the control intervention (n = 279), which had previously been demonstrated to be clinically effective (brief web-based information that minimised pressure to cut down foods, instead encouraging swaps to healthier choices and increasing fruit and vegetables, plus 6-monthly nurse weighing); (2) POWeR+F (n = 269), POWeR+ supplemented by face-to-face nurse support (up to seven contacts); or (3) POWeR+R (n = 270), POWeR+ supplemented by remote nurse support (up to five e-mails or brief telephone calls). MAIN OUTCOME MEASURES The primary outcome was a modelled estimate of average weight reduction over 12 months, assessed blind to group where possible, using multiple imputation for missing data. The secondary outcome was the number of participants maintaining a 5% weight reduction at 12 months. RESULTS A total of 818 eligible individuals were randomised using computer-generated random numbers. Weight change, averaged over 12 months, was documented in 666 out of 818 participants (81%; control, n = 227; POWeR+F, n = 221; POWeR+R, n = 218). The control group maintained nearly 3 kg of weight loss per person (mean weight per person: baseline, 104.4 kg; 6 months, 101.9 kg; 12 months, 101.7 kg). Compared with the control group, the estimated additional weight reduction with POWeR+F was 1.5 kg [95% confidence interval (CI) 0.6 to 2.4 kg; p = 0.001] and with POWeR+R was 1.3 kg (95% CI 0.34 to 2.2 kg; p = 0.007). By 12 months the mean weight loss was not statistically significantly different between groups, but 20.8% of control participants, 29.2% of POWeR+F participants (risk ratio 1.56, 95% CI 0.96 to 2.51; p = 0.070) and 32.4% of POWeR+R participants (risk ratio 1.82, 95% CI 1.31 to 2.74; p = 0.004) maintained a clinically significant 5% weight reduction. The POWeR+R group had fewer individuals who reported doing another activity to help lose weight [control, 47.1% (64/136); POWeR+F, 37.2% (51/137); POWeR+R, 26.7% (40/150)]. The incremental cost to the health service per kilogram weight lost, compared with the control group, was £18 (95% CI -£129 to £195) for POWeR+F and -£25 (95% CI -£268 to £157) for POWeR+R. The probability of being cost-effective at a threshold of £100 per kilogram was 88% and 98% for POWeR+F and POWeR+R, respectively. POWeR+R was dominant compared with the control group. No harms were reported and participants using POWeR+ felt more enabled in managing their weight. The qualitative studies documented that POWeR+ was viewed positively by patients and that health-care professionals generally enjoyed supporting patients using POWeR+. STUDY LIMITATIONS Maintenance of weight loss after 1 year is unknown. FUTURE WORK Identifying strategies for longer-term engagement, impact in community settings and increasing physical activity. CONCLUSION Clinically valuable weight loss (> 5%) is maintained in 20% of individuals using novel written materials with brief follow-up. A web-based behavioural programme and brief support results in greater mean weight loss and 10% more participants maintain valuable weight loss; it achieves greater enablement and fewer participants undertaking other weight-loss activities; and it is likely to be cost-effective.

The aim of this study is to determine the effect of dietary pitamin as an antibiotic replacement in broiler chicken. The treated groups were as follows: 1) the control, 2) the antibiotics (8 mg of avilamycin kg(-1) of diet) and 3) the pitamin (70 mg of pitamin kg(-1) of diet) groups. Body weight gain, feed intake, and feed efficiency were significantly higher in the pitamin group than in the antibiotics and control groups (p<0.05). Carcass weight, dressing percentage, and the weight of breast and thigh muscle recorded significantly higher levels in the pitamin group as compared to the other groups (p<0.05). The addition of pitamin to the diets for broilers reduced abdominal fat by 23.35% and stimulated the growth of the thymus, the spleen, and the bursa of Fabricius. TAG levels of the pitamin group declined by 12.03 and 10.45% as compared to the control and antibiotics groups, and their TC levels were reduced by 15.17 and 14.39%, and LDL. C levels were reduced by 10.56 and 11.24%, respectively. Serum IgG was increased significantly by 137.43 and 36.80% in the pitamin group as compared to the control and antibiotics groups, respectively (p<0.05). The numbers of Bifidobacterium and Lactobacillus on the cecum digesta were significantly higher in the pitamin group than in the antibiotics and control groups and the numbers of Escherichia coli and Salmonella tended to be reduced (p<0.05). In conclusion, when Korean red pine bark extract, pitamin, was added to the broiler diets at a concentration of 70 mg of pitamin kg(-1) of diet, it resulted in better growth performance as compared to the antibiotics by improving immunity and the cecal beneficial microfloral population.

To determine an influence of alpha-lipoic acid to reduction of body weight and regulation of total cholesterol concentration, triglycerides and glucose serum levels in obese patients with diabetes mellitus type 2. A prospective study includes two groups of obese patients with diabetes mellitus and signs of peripheral polyneuropathia: examined group (30 patients; 15 females and 15 males), and control group (30 patients; 12 females and 18 males). All were treated with metformin (850-1700 mg/day). Examined patients were additionally treated with alpha-lipoic acid 600 mg/day during 20 weeks. Body mass index and concentrations of total cholesterol, triglycerides and glucose in serum were compared before and after the treatment. The group treated with 600 mg alpha-lipoic acid lost significantly more weight, and had lower triglyceride level than the control group. There were no significant differences in total cholesterol and glucose serum levels between the groups. Alpha-lipoic acid of 600 mg/day treatment have influenced weight and triglycerides loss in obese patients with diabetes mellitus type 2. It should be considered as an important additive therapy in obese patients with diabetes mellitus type 2. Copyright© by the Medical Assotiation of Zenica-Doboj Canton.

Type 2 diabetes is a chronic disorder that requires lifelong treatment. We aimed to assess whether intensive weight management within routine primary care would achieve remission of type 2 diabetes. We did this open-label, cluster-randomised trial (DiRECT) at 49 primary care practices in Scotland and the Tyneside region of England. Practices were randomly assigned (1:1), via a computer-generated list, to provide either a weight management programme (intervention) or best-practice care by guidelines (control), with stratification for study site (Tyneside or Scotland) and practice list size (>5700 or ≤5700). Participants, carers, and research assistants who collected outcome data were aware of group allocation; however, allocation was concealed from the study statistician. We recruited individuals aged 20-65 years who had been diagnosed with type 2 diabetes within the past 6 years, had a body-mass index of 27-45 kg/m 2 , and were not receiving insulin. The intervention comprised withdrawal of antidiabetic and antihypertensive drugs, total diet replacement (825-853 kcal/day formula diet for 3-5 months), stepped food reintroduction (2-8 weeks), and structured support for long-term weight loss maintenance. Co-primary outcomes were weight loss of 15 kg or more, and remission of diabetes, defined as glycated haemoglobin (HbA 1c ) of less than 6·5% (<48 mmol/mol) after at least 2 months off all antidiabetic medications, from baseline to 12 months. These outcomes were analysed hierarchically. This trial is registered with the ISRCTN registry, number 03267836. Between July 25, 2014, and Aug 5, 2017, we recruited 306 individuals from 49 intervention (n=23) and control (n=26) general practices; 149 participants per group comprised the intention-to-treat population. At 12 months, we recorded weight loss of 15 kg or more in 36 (24%) participants in the intervention group and no participants in the control group (p<0·0001). Diabetes remission was achieved in 68 (46%) participants in the intervention group and six (4%) participants in the control group (odds ratio 19·7, 95% CI 7·8-49·8; p<0·0001). Remission varied with weight loss in the whole study population, with achievement in none of 76 participants who gained weight, six (7%) of 89 participants who maintained 0-5 kg weight loss, 19 (34%) of 56 participants with 5-10 kg loss, 16 (57%) of 28 participants with 10-15 kg loss, and 31 (86%) of 36 participants who lost 15 kg or more. Mean bodyweight fell by 10·0 kg (SD 8·0) in the intervention group and 1·0 kg (3·7) in the control group (adjusted difference -8·8 kg, 95% CI -10·3 to -7·3; p<0·0001). Quality of life, as measured by the EuroQol 5 Dimensions visual analogue scale, improved by 7·2 points (SD 21·3) in the intervention group, and decreased by 2·9 points (15·5) in the control group (adjusted difference 6·4 points, 95% CI 2·5-10·3; p=0·0012). Nine serious adverse events were reported by seven (4%) of 157 participants in the intervention group and two were reported by two (1%) participants in the control group. Two serious adverse events (biliary colic and abdominal pain), occurring in the same participant, were deemed potentially related to the intervention. No serious adverse events led to withdrawal from the study. Our findings show that, at 12 months, almost half of participants achieved remission to a non-diabetic state and off antidiabetic drugs. Remission of type 2 diabetes is a practical target for primary care. Diabetes UK. Copyright © 2018 Elsevier Ltd. All rights reserved.

Horses are hosts to a wide variety of helminthes; the most important are the cyathostomin, or small strongyles. The viability of a fungal formulation (pellets) using the nematode-trapping fungus Monacrosporium thaumasium was assessed in biological control of horse cyathostomin. Two groups (fungus-treated and control) consisted of six mares in each group, crossbred (ages of 2.5 and 3.5 years), were placed in pastures of Cynodon sp. naturally infected with horse cyathostomin larvae. In the treated group, each animal received 1g/10 kg body weight (0.2g/10 kg live weight of fungus) of pellets of sodium alginate matrix containing the fungus M. thaumasium orally, twice a week for 6 months. In the control group, animals received (1g/10 kg body weight) of pellets without fungus. The egg count per gram of feces showed difference (p<0.01) in the animals treated with the fungus in relation to the control animals during all months of the experiment. The EPG percentage decrease were 87.5%, 89.7%, 68.3%, 58.7%, 52.5% and 35.2% during June, July, August, September, October and November, respectively. In faecal cultures, there was difference (p<0.05) among animals treated with fungus was found in relation to the control animals during all the experiment month, with percentage reduction of 67.5%, 61.4% and 31.8% in September, October and November, respectively. Difference (p<0.01) was observed in the recovery of infective larvae from pastures that were collected up to 20 cm from the dung pats in pastures in the group treated with the fungus in relation to the control group with a reduction of 60.9% and between 0-20 and 0-40 cm from the faecal pat reduction (p<0.01) was about 56% in the group treated with the fungus M. thaumasium in relation to the control group pasture. There was no difference (p>0.05) between the average weight gains in both animal groups. The treatment of horses with pellets containing the nematophagous fungus M. thaumasium can be effective in controlling cyathostomin in the tropical region of southeastern Brazil.

Angiotensinogen (AGT) has been shown to have a role in cardiac hypertrophy, while depletion of the AGT gene in spontaneously hypertensive rats (SHR) has not been investigated. The present study investigated the effect of AGT knockdown on cardiac hypertrophy in SHR. For this, small hairpin (sh)RNAs were intravenously injected into SHRs, using a nanoparticle‑mediated transfection system. The experimental rats were divided into the following groups: a) Blank control with water treatment only, b) negative control with biscarbamate‑crosslinked Gal‑polyethylene glycol polyethylenimine nanoparticles (GPE)/negative shRNA, c) AGT‑RNA interference (RNAi) group with GPE/AGT‑shRNA, and 4) normotensive control using Wistar‑Kyoto rats (WKY) with water treatment. Three and five days following the first injection, the levels of hepatic AGT mRNA and AGT protein as well as plasma levels of AGT were markedly decreased in the AGT‑RNAi group (P<0.05). Furthermore, a significant decrease in systolic blood pressure (SBP), left ventricular weight to body weight ratio and heart weight to body weight ratio were observed in the AGT‑RNAi group compared with those in the control groups. The depletion of AGT in SHR led to a reduction in SBP by 30±4 mmHg, which was retained for >10 days. Cardiac hypertrophy was also significantly improved in AGT‑knockdown rats. In conclusion, the present study showed that AGT‑silencing had a significant inhibitory effect on hypertension and hypertensive‑induced cardiac hypertrophy in SHRs.

Cirrhotic animal models are useful in studying complications of chronic liver disease. The authors chronologically investigated the effect of thioacetamide (TAA), administered intraperitoneally and adapted individually to weight changes, focusing on the optimal moment to obtain typical features of cirrhosis. Male Wistar Rats,150-200 g, were intoxicated three times per week with TAA of 200 mg/kg for 4, 8, 12 or 16 weeks (n = 8 per group), respectively and compared with age-matched controls (n = 4 per group). The individual body weight and liver function test were also measured in each group. Liver samples from each group were histologically stained with Sirius red in order to identify the degree of liver fibrosis. Rats intoxicated for 4, 8, 12 or 16 weeks had no mortality and histologically showed hepatitis and advanced fibrosis. At 12 and 16 weeks, all animals showed macronodular cirrhosis with signs of high-grade hepatocellular dysplasia. The weight of the treated groups at different time points was significantly lower than the controls. Routine liver function tests between cirrhotic and control rats showed significantly higher only in alanine transaminase (ALT) and aspartate aminotransferase (AST) at 8 and 12 weeks. However in the cirrhotic rats at 16 weeks, the ALT and AST were much lower than that at 8 and 12 weeks but did not show any difference from the controls. Thioacetamide, adapted to individual weight changes, leads to a model of cirrhosis in the rat at 12 and 16 weeks with zero mortality.

Advanced cancer patients with disease progression develop cachexia. Nevertheless, cancer patients at nutritional risk have shown improved body weight and quality of life with oral nutritional supplements. This was a randomized controlled trial in adult female cancer patients (n = 63) attending palliative clinics, with symptoms of cachexia. Eligible patients were randomly distributed into control (n = 33) and intervention (n = 30) groups. Both groups were provided with nutritional and physical activity counseling, but the intervention group received an additional 100 g of Improved Atta (IAtta) for 6 months daily consumption. This study was designed to assess the efficacy of IAtta (with counseling) in enhancing the health status of cachexic patients. Anthropometric measurements, dietary intake, physical activity level and quality of life parameters were assessed at baseline, after 3 months, and at the end of 6 months. Patients in the control group (n = 15) had significantly decreased body weight ( P = .003), mid-upper-arm circumference ( P = .002), and body fat ( P = .002) by the end of intervention. A trend of body weight gain in the intervention group (n = 17; P = .08) and significant increase of body fat ( P = .002) was observed; moreover, patients reported a significant improvement in fatigue ( P = .002) and appetite scores ( P = .006) under quality-of-life domains at the end of intervention. Embedding a nutrition-sensitive intervention ( IAtta ) within Indian palliative care therapy may improve quality of life and stabilize body weight in cancer cachexia patients.

This study investigated the impact of microalgal oil (MO) on body weight management in C57BL/6J mice. Obesity was induced for 8 weeks and animals were orally supplemented with the following for 8 additional weeks: beef tallow (BT), corn oil, fish oil (FO), microalgal oil (MO), or none, as a high fat diet control group (HD). A normal control group was fed with a normal diet. After completing the experiment, the FO and MO groups showed significant decreases in body weight gain, epididymal fat pad weights, serum triglycerides, and total cholesterol levels compared to the HD and BT groups. A lower mRNA expression level of lipid anabolic gene and higher levels of lipid catabolic genes were observed in both FO and MO groups. Serum insulin and leptin concentrations were lower in the MO group. These results indicated that microalgal oil has an anti-obesity effect that can combat high fat diet-induced obesity in mice.

Fifty mature pony stallions were randomly assigned to one of five treatment groups: Group 1- controls (no treatment), Group 2 - 0.55 mg/kg stanozolol weekly for 13 treatments, Group 3 - 1.1 mg/kg stanozolol every 3 weeks for 5 treatments, Group 4 - 1.1 mg/kg boldenone undecylenate every 3 weeks for 5 treatments, and Group 5 - 0.55 mg/kg boldenone undecylenate weekly for 13 treatments. Scrotal widths (SW), combined testis weights (CTW), and daily sperm productions (DSP) were not different between Groups 1 and 2. Ponies in Group 5 had smaller SW (P<0.01), smaller CTW and decreased DSP compared to controls (P < 0.05). Although SW for ponies in Groups 3 and 4 were less than for controls (P < 0.01), CTW and DSP were not different. The only treatment regime that did not alter SW, CTW, and DSP was Group 2 (0.55 mg/kg stanozolol weekly for 13 treatments).

Background A major challenge following successful weight loss is continuing the behaviors required for long-term weight maintenance. This challenge may be exacerbated in rural areas with limited local support resources. Objective This study describes and compares program costs and cost-effectiveness for 12-month extended care lifestyle maintenance programs following an initial 6-month weight loss program. Design A 1-year prospective controlled randomized clinical trial. Participants/Setting The study included 215 female participants age 50 or older from rural areas who completed an initial 6-month lifestyle program for weight loss. The study was conducted from June 1, 2003, to May 31, 2007. Intervention The intervention was delivered through local Cooperative Extension Service offices in rural Florida. Participants were randomly-assigned to a 12-month extended care program using either individual telephone counseling (n=67), group face-to-face counseling (n=74), or a mail/control group (n=74). Main Outcome Measures Program delivery costs, weight loss, and self-reported health status were directly assessed through questionnaires and program activity logs. Costs were estimated across a range of enrollment sizes to allow inferences beyond the study sample. Statistical Analyses Performed Non-parametric and parametric tests of differences across groups for program outcomes were combined with direct program cost estimates and expected value calculations to determine which scales of operation favored alternative formats for lifestyle maintenance. Results Median weight regain during the intervention year was 1.7 kg for participants in the face-to-face format, 2.1 kg for the telephone format, and 3.1 kg for the mail/control format. For a typical group size of 13 participants, the face-to-face format had higher fixed costs, which translated into higher overall program costs ($420 per participant) when compared to individual telephone counseling ($268 per participant) and control ($226 per participant) programs. While the net weight lost after the 12-month maintenance program was higher for the face-to-face and telephone programs compared to the control group, the average cost per expected kilogram of weight lost was higher for the face-to-face program ($47/kg) compared to the other two programs (approximately $33/kg for telephone and control). Conclusions Both the scale of operations and local demand for programs are important considerations in selecting a delivery format for lifestyle maintenance. In this study, the telephone format had a lower cost, but similar outcomes compared to the face-to-face format. PMID:22818246

To evaluate the efficacy of the five ear acupuncture points (Shen-men, Spleen, Stomach, Hunger, Endocrine), generally used in Korean clinics for treating obesity, and compare them with the Hunger acupuncture point. A randomised controlled clinical trial was conducted in 91 Koreans (16 male and 75 female, body mass index (BMI)≥23), who had not received any other weight control treatment within the past 6 months. Subjects were divided randomly into treatment I, treatment II or sham control groups and received unilateral auricular acupuncture with indwelling needles replaced weekly for 8 weeks. Treatment I group received acupuncture at the five ear acupuncture points, treatment II group at the Hunger acupuncture point only and the sham control group received acupuncture at the five ear acupuncture points used in treatment I, but the needles were removed immediately after insertion. BMI, waist circumference, weight, body fat mass (BFM), percentage body fat and blood pressure were measured at baseline and at 4 and 8 weeks after treatment. For the 58 participants who provided data at 8 weeks, significant differences in BMI, weight and BFM were found between the treatment and control groups. Treatment groups I and II showed 6.1% and 5.7% reduction in BMI, respectively (p<0.004). There were no significant differences between the two treatment groups. This finding suggests that the five ear acupuncture points, generally used in Korean clinics, and the Hunger point alone treatment are both effective for treating overweight people.

Obesity is one of the most common public health problems in the industrialized world as a cause of noncommunicable diseases. Although primarily used for one-on-one communication, email is available for uninterrupted support for weight loss, but little is known about the effects of dietitian group counseling for weight control via the Internet. We developed a Web-based self-disclosure health support (WSHS) system for weight loss. This study aims to compare the effect of weight change between those using the WSHS and those using the email health support (EHS). This study was designed as an open prospective individual randomized controlled trial. Eligible participants were aged 35 to 65 years with a body mass index (BMI) of ≥25.0 in their latest health examination. Participants were randomly assigned to either the WSHS group or the EHS group. Thirteen registered dietitians under the direction of a principal dietitian each instructed 6 to 8 participants from the respective groups. All participants in the WSHS group could receive nutritional advice and calculate their nutritive intake from a photograph of a meal on their computer screen from the Internet sent to them by their dietitian, receive supervision from the registered dietitian, and view fellow participants' weight changes and lifestyle modifications. In the EHS group, a participant could receive one-on-one nutritional advice and calculate his/her nutritive intake from the photograph of a meal on computer screen sent by email from his/her dietitian, without being able to view fellow participants' status. The follow-up period was 12 weeks for both groups. The primary outcome measure was change in body weight. The secondary outcome measure included changes in BMI and waist circumference. The intergroup comparison of the changes before and after intervention was evaluated using analysis of covariance. A total of 193 participants were randomly assigned to either the WSHS group (n=97) or the EHS group (n=96). Ten from the WSHS group and 8 from the EHS group dropped out during the study period, and the remaining 87 in the WSHS group and 88 in the EHS group were followed up completely. Weight loss was significantly greater in the WSHS group than in the EHS group (-1.6 kg vs -0.7 kg; adjusted P=.04). However, there were few differences in waist circumference between the 2 groups. (-3.3 cm vs -3.0 cm; adjusted P=.71). Our newly developed WSHS system using forced self-disclosure had better short-term weight loss results. Further study in a longer-term trial is necessary to determine what effects this type of intervention might have on long-term cardiovascular disease.

Eating and weight/shape criticism as a specific life-event related to bulimia nervosa: a case control study.

PubMed

Gonçalves, Sonia Ferreira; Machado, Bárbara César; Martins, Carla

2014-01-01

The present study aims to evaluate the occurrence of life events preceding the onset of eating problems in bulimia nervosa patients. A case-control design was used involving the comparison of 60 female subjects who meet DSM-IV criteria for bulimia nervosa with 60 healthy control subjects and 60 subjects with other psychiatric disorders. The RFI (Fairburn et al., 1998) subset of factors that represent exposure to life events in the 12 months immediately before the development of eating problems was used. Women with bulimia nervosa reported higher rates of major stress, criticism about eating, weight and shape and also a great number of antecedent life events during the year preceding the development of eating problems than the healthy control group. However, when compared with the general psychiatric control group only the exposure to critical comments about weight, shape, or eating emerged as a specific trigger for bulimia nervosa. Our findings support the fact that eating and shape/weight criticism in the year preceding the development of eating disturbance seems to be specifically related to bulimia nervosa.

In order to determine the tolerable upper intake level of folic acid in humans, we investigated the effects of excessive folic acid administration on the body weight gain, food intake, tissue weight, and metabolism of B-group vitamins in weaning rats. The rats were freely fed ordinary diet containing 0.0002% folic acid (control diet) or the same diet with 0.01%, 0.1%, or 1.0% folic acid for 29 days. The body weight gains and food intakes did not differ among the four groups. Diarrhea was not seen even in the 1.0% group. Excess folic acid did not affect the tissue weights of the brain, heart, liver, kidney, spleen, lung, or testis, or urinary excretion of other B-group vitamins. These results clearly showed that feeding a diet containing up to 1.0% folic acid did not affect the food intake, body weight gain, tissue weight, or urinary excretion of B-group vitamins in weaning rats.

The objective of this study was to determine whether habit-based interventions are clinically beneficial in achieving long-term (12-month) weight loss maintenance and explore whether making new habits or breaking old habits is more effective. Volunteer community members aged 18-75 years who had overweight or obesity (BMI ≥ 25 kg/m 2 ) were randomized in a single-blind, three-arm, randomized controlled trial. Ten Top Tips (TTT), Do Something Different (DSD), and the attention-only waitlist (WL) control groups were conducted for 12 weeks from July to October 2015. Participants were followed up post-intervention (all groups) and at 6 and 12-month post-intervention (Ten Top Tips and Do Something Different only). The primary outcome was weight-loss maintenance at 12-month follow-up. Secondary outcomes included weight loss at all time points, fruit and vegetable consumption, exercise, wellbeing, depression, anxiety, habit strength, and openness to change. Of the 130 participants assessed for eligibility, 75 adults (mean BMI 34.5 kg/m 2 [SD 6.2]), with a mean age of 51 years were recruited. Assessments were completed post-intervention by 66/75 (88%) of participants and by 43/50 (86%) at 12 months. At post-intervention, participants in the Ten Top Tips (-3.3 kg; 95% CI -5.2, -1.4) and Do Something Different (-2.9 kg; 95% CI -4.3, -1.4) interventions lost significantly more weight (P = < .001) than those on the waitlist control (-0.4 kg; 95% CI -1.2, 0.3). Both intervention groups continued to lose further weight to the 12-month follow-up; TTT lost an additional -2.4 kg (95% CI -5.1, 0.4) and DSD lost -1.7 kg (95% CI -3.4, -0.1). At 12-month post-intervention, 28/43 (65%) of participants in both intervention groups had reduced their total body weight by ≥5%, a clinically important change. Habit-based weight-loss interventions-forming new habits (TTT) and breaking old habits (DSD), resulted in clinically important weight-loss maintenance at 12-month follow-up.

Few randomized controlled trials (RCTs) of interventions for the treatment of childhood obesity have taken place outside the Western world. To test whether a good practice intervention for the treatment of childhood obesity would have a greater impact on weight status and other outcomes than a control condition in Kuala Lumpur, Malaysia. Assessor-blinded RCT of a treatment intervention in 107 obese 7- to 11-year olds. The intervention was relatively low intensity (8 hours contact over 26 weeks, group based), aiming to change child sedentary behavior, physical activity, and diet using behavior change counselling. Outcomes were measured at baseline and six months after the start of the intervention. Primary outcome was BMI z-score, other outcomes were weight change, health-related quality of life (Peds QL), objectively measured physical activity and sedentary behavior (Actigraph accelerometry over 5 days). The intervention had no significant effect on BMI z score relative to control. Weight gain was reduced significantly in the intervention group compared to the control group (+1.5 kg vs. +3.5 kg, respectively, t-test p < 0.01). Changes in health-related quality of life and objectively measured physical activity and sedentary behavior favored the intervention group. Treatment was associated with reduced rate of weight gain, and improvements in physical activity and quality of life. More substantial benefits may require longer term and more intensive interventions which aim for more substantive lifestyle changes.

There is a growing concern that food or cash transfer programs may contribute to overweight and obesity in adults. We studied the impact of Mexico's Programa de Apoyo Alimentario (PAL), which provided very poor rural households with cash or in-kind transfers, on women's body weight. A random sample of 208 rural communities in southern Mexico was randomly assigned to 1 of 4 groups: food basket with or without health and nutrition education, cash with education, or control. The impact on women's weight was estimated in a cohort of 3010 women using a difference-in-difference model. We compared the impact between the food basket and cash groups and evaluated whether the impact was modified by women's BMI status at baseline. With respect to the control group, the program increased women's weight in the food basket (550 ± 210 g; P = 0.004) and the cash group (420 ± 230 g; P = 0.032); this was equivalent to 70 and 53% increases in weight gain, respectively, over that observed in the control group in a 23-mo time period. The greatest impact was found in already obese women: 980 ± 290 g in the food basket group (P = 0.001) and 670 ± 320 g in the cash group (P = 0.019). Impact was marginally significant in women with a preprogram BMI between 25 and 30 kg/m2: 490 ± 310 g (P = 0.055) and 540 ± 360 g (P = 0.067), respectively. No program impact was found in women with a BMI <25 kg/m2. Providing households with a considerable amount of unrestricted resources led to excess weight gain in an already overweight population. Research is needed to develop cost-effective behavior change communication strategies to complement cash and in-kind transfer programs such as PAL and to help beneficiaries choose healthy diets that improve the nutritional status of all family members.

Thirty-six Holstein cross calves 5 days of age in their preruminant stage were used to study the effect of feeding prebiotic (mannanoligosaccharide) on their performance up to the age of 2 months. Treatment and control groups consisted of 18 calves each. Treatment group was supplemented with 4 g prebiotic (mannanoligosaccharide)/calf/day. Performance was evaluated by measuring average body weight (BW) gain, feed intake [dry matter (DM), total digestible nutrient (TDN) and crude protein(CP)], feed conversion efficiency (DM, TDN, and CP), fecal score, fecal coliform count and feeding cost. Body weight measured weekly, feed intake measured twice daily, proximate analysis of feeds and fodders analyzed weekly, fecal score monitored daily and fecal coliform count done weekly. There was a significant increase in average body weight gain, feed intake and feed conversion efficiency; and a significant decrease in severity of scours as measured by fecal score and fecal coliform count in the treatment group compared with control group (P < 0.01). Feed cost/kg BW gain was significantly lower in the treatment group compared to control group (P < 0.01). The results suggest that prebiotic (mannanoligosaccharide) can be supplemented to the calves for better performance.

Antipsychotics, especially atypical ones, are in common use in children and adolescents with psychotic or affective spectrum disorders, as well as in various other psychopathologies. The adverse effects of atypical antipsychotics in children and adolescents are similar to those seen in adults, and include weight gain, elevated blood glucose levels, and hyperlipidemia. In this retrospective chart review, we compared these adverse events in children who were treated with typical, atypical, or no antipsychotic treatment. The medical charts of 72 children, 65 boys and 7 girls, were reviewed. All children were 6-13 years old (mean age 9.5±1.7 years). In total, 48 children received antipsychotic treatment, and 24 children were in the control group. Data were extracted from the medical charts, including weight, height, body mass index (BMI), blood pressure, aspartate transaminase (AST), alanine transaminase (ALT), triglycerides, total cholesterol, and glucose blood levels. We examined the values in the beginning of the antipsychotic treatment and at release from the hospital in the study group, and at admission and in the end of the drug-free period or at release from the hospital (a duration of at least 4 weeks) in the control group. The average weight gain was 3.9±3.8 kg in the atypical antipsychotic treatment (AAT) group, 1.1±4.4 kg in the typical antipsychotic treatment (TAT) group, and 0.23±2.9 kg in the control group. The average increase in BMI was 15.1±22.0 percentiles in the AAT group, 6.4±14.2 percentiles in the TAT group, and 1.6±12.5 percentiles in the control group. No statistically significant difference was found in the increase in height percentile. There were no significant differences in the rates of elevated values of serum triglycerides, cholesterol, AST, ALT, or fasting blood glucose. We found a significant increase in both absolute weight gain and BMI percentile following atypical antipsychotic treatment. In contrast, typical antipsychotic treatment did not affect weight gain significantly, and the same was true for the control group. In addition, the rates of elevated values of biochemical parameters (AST, ALT, total cholesterol, triglycerides, and fasting blood glucose levels) were very low at the beginning of the study, and were not significantly altered by the various treatments.

To study the effects of early high fat diet on sugar metaboliam, insulin sensibility and pancreatic β cellularity in young rats. Sixty male weaned young rats were randomly fed with high fat diet (high fat group) and normal diet (control group). The body weight, viscus fattiness and fasting plasma glucose (FPG) were measured after 3, 6 and 9 weeks. Serum insulin level was measured with radioimmunoassay. The ultrastructure of pancreas was observed under an electricmicroscope. The high fat group had significantly higher body weight and visceral fat weight than the control group after 3 weeks. There were no significant differences in the FPG level between the two groups at all time points. The levels of fasting insulin and HOMAIR in the high fat group were significantly higher than those in the control group after 3, 6 and 9 weeks (P<0.01). Dilation of rough endoplasmic reticulum and mild swelling of mitochondria of islet β-cells were observed in the high fat group after 6 weeks. Early high fat diet may induce a reduction in insulin sensitivity and produce insulin resistance in young rats. Endoplasmic reticulum expansion in β-cells may be an early sign of β-cell damage due to obesity.

Intermuscular adipose tissue (IMAT) and visceral adipose tissue (VAT) are associated with insulin resistance. We sought to determine whether exercise-induced weight loss (EX) results in greater reductions in IMAT and VAT compared with similar weight loss induced by calorie restriction (CR) and whether these changes are associated with improvements in glucoregulation. Sedentary men and women (50–60 yr; body mass index of 23.5–29.9 kg/m2) were randomized to 1 yr of CR (n = 17), EX (n = 16), or a control group (CON; n = 6). Bilateral thigh IMAT and VAT volumes were quantified using multi-slice magnetic resonance imaging. Insulin sensitivity index (ISI) was determined from oral glucose tolerance test glucose and insulin levels. Weight loss was comparable (P = 0.25) in the CR (−10.8 ± 1.4%) and EX groups (−8.3 ± 1.5%) and greater than in the control group (−2.0 ± 2.4%; P < 0.05). IMAT and VAT reductions were larger in the CR and EX groups than in the CON group (P ≤ 0.05). After controlling for differences in total fat mass change between the CR and EX groups, IMAT and VAT reductions were nearly twofold greater (P ≤ 0.05) in the EX group than in the CR group (IMAT: −45 ±5 vs. −25 ± 5 ml; VAT: −490 ± 64 vs. −267 ± 61 ml). In the EX group, the reductions in IMAT were correlated with increases in ISI (r = −0.71; P = 0.003), whereas in the CR group, VAT reductions were correlated with increases in ISI (r = −0.64; P = 0.006). In conclusion, calorie restriction and exercise-induced weight loss both decrease IMAT and VAT volumes. However, exercise appears to result in preferential reductions in these fat depots.

The purpose of this study was to investigate the influence of apple pomace (AP) and apple juice concentrate (AC) supplementation on body weight and fat loss as well as lipid metabolism in obese rats fed a high-fat diet. Diet-induced obese rats were assigned to three groups (n=8 for each group): high fat diet (HFD) control, HFD containing 10% (w/w) AP, and HFD containing 10% (w/w) AC. There was also a normal diet group (n=8). After 5 weeks, body weight gain, adipose tissue weight, serum and hepatic lipid profiles, liver morphology, and adipocyte size were measured. Body weight gain, white adipose tissue (WAT) weight, serum total cholesterol, low-density lipoprotein cholesterol and triglyceride concentrations, epididymal adipocyte size, and lesion scores were significantly lower and serum high-density lipoprotein cholesterol concentration and brown adipose tissue weights were significantly higher in the AP and AC groups compared with the HFD group. In addition, atherogenic indices in the AP and AC groups were significantly lower than in the HFD group. These results indicate that supplementing apple products such as AP and AC may help suppress body weight and WAT gain, as well as improve lipid profiles in diet-induced obese rats.

While commercial dietary weight-loss programs typically advise exercise, few provide actual programing. The goal of this study was to compare the Curves Complete 90-day Challenge (CC, n = 29), which incorporates exercising and diet, to programs advocating exercise (Weight Watchers Points Plus (WW, n = 29), Jenny Craig At Home (JC, n = 27), and Nutrisystem Advance Select (NS, n = 28)) or control (n = 20) on metabolic syndrome (MetS) and weight loss. We randomized 133 sedentary, overweight women (age, 47 ± 11 years; body mass, 86 ± 14 kg; body mass index, 35 ± 6 kg/m 2 ) into respective treatment groups for 12 weeks. Data were analyzed using chi square and general linear models adjusted for age and respective baseline measures. Data are means ± SD or mean change ± 95% confidence intervals (CIs). We observed a significant trend for a reduction in energy intake for all treatment groups and significant weight loss for all groups except control: CC (-4.32 kg; 95% CI, -5.75, -2.88), WW (-4.31 kg; 95% CI, -5.82, -2.96), JC (-5.34 kg; 95% CI, -6.86, -3.90), NS (-5.03 kg; 95% CI, -6.49, -3.56), and control (0.16 kg, 95% CI, -1.56, 1.89). Reduced MetS prevalence was observed at follow-up for CC (35% vs. 14%, adjusted standardized residuals (adjres.) = 3.1), but not WW (31% vs. 28% adjres. = 0.5), JC (37% vs. 42%, adjres. = -0.7), NS (39% vs. 50% adjres. = -1.5), or control (45% vs. 55% adjres. = -1.7). While all groups improved relative fitness (mL·kg -1 ·min -1 ) because of weight loss, only the CC group improved absolute fitness (L/min). In conclusion, commercial programs offering concurrent diet and exercise programming appear to offer greater improvements in MetS prevalence and cardiovascular function after 12 weeks of intervention.

Background. There is limited information on the effectiveness of meal replacements (MRs) as a weight-loss strategy in an unsupervised community setting. Aim. To evaluate the use of MR compared with a diet book for 6 months. Subjects and Methods. Obese subjects (n = 120) with type 2 diabetes mellitus were recruited from the community in Adelaide, South Australia, and randomised to intervention or control. Subjects in the intervention were advised to consume 2 MR/day for 3 months and 1 MR/day for 3 months and follow the manufacturers' instructions from printed material and the website. Subjects in the control arm were given a commercially available diet book. Results. Consumption of 2 MR for 3 months and 1 MR for the subsequent 3 months led to weight loss of 5.5 kg (5%) and a 0.26% decrease in HbA1c while the diet book group had a weight loss of 3 kg (3%) (P = 0.027 for difference between groups) and a decrease in HbA1c of 0.15% (between group ns) in those who completed the 6-month study. On intention-to-treat (last observation carried forward) weight loss at 6 months was 3.4 kg in MR and 1.8 kg in control (P = 0.07). Decreases in HbA1c were 0.22% and 0.12%, respectively (P = ns). HDL cholesterol increased by 4% in MR and decreased by 1% in control (P = 0.004). Blood pressure decreased equally in both groups. There were reductions in fasting glucose in both groups at 6 months with no changes in LDL-cholesterol or triglyceride concentrations. Conclusion. MR confers benefits in HbA1C reduction and weight loss at 6 months in those who completed the study.

OBJECTIVE This multicenter non-inferiority study evaluated the safety of infant formulas enriched with bovine milk fat globule membrane (MFGM) fractions. METHODS Healthy, full-term infants (n = 119) age ≤14 days were randomized to standard infant formula (control), standard formula enriched with a lipid-rich MFGM fraction (MFGM-L), or standard formula enriched with a protein-rich MFGM fraction (MFGM-P). Primary outcome was mean weight gain per day from enrollment to age 4 months (non-inferiority margin: −3.0 g/day). Secondary (length, head circumference, tolerability, morbidity, adverse events) and exploratory (phospholipids, metabolic markers, immune markers) outcomes were also evaluated. RESULTS Weight gain was non-inferior in the MFGM-L and MFGM-P groups compared with the control group. Among secondary and exploratory outcomes, few between-group differences were observed. Formula tolerance rates were high (>94%) in all groups. Adverse event and morbidity rates were similar across groups except for a higher rate of eczema in the MFGM-P group (13.9% vs control [3.5%], MFGM-L [1.4%]). CONCLUSION Both MFGM-enriched formulas met the primary safety endpoint of non-inferiority in weight gain and were generally well tolerated, although a higher rate of eczema was observed in the MFGM-P group.

Effects of radiating ostrich eggs before incubation on hatchability, growth performance, and some blood components of ostrich chicks were studied. 72 ostrich eggs were randomly distributed into four groups. The first group was kept without exposure to gamma radiation (control). The 2nd, 3rd, and 4th groups were exposed to 0.8, 1.6, and 3.2 Gy, respectively, of 60 Co gamma rays just before incubation. Total bacterial counts (×10 3  CFU) were significantly increased with the increase in gamma radiation levels before incubation. Feed conversion was lower (P ≤ 0.01) in the control group than those irradiated. Embryonic mortality rate (%), hatchability (%) and chick weight at hatch, body weight, daily body weight gain, feed consumption, and all of hematology parameters studied were insignificantly fluctuated with the doses of gamma rays used. Serum concentrations of total protein, albumen, globulin, glucose, and triiodothyronin of the chicks from eggs of the control and the 1st group were significantly the highest. Chicks of the control group had significantly the lowest values of serum concentrations of uric acid, creatinine, triglyceride, total cholesterol, ALT, and AST when compared with the other groups. In conclusion, radiation of ostrich eggs before incubation with a dose of 0.8 Gy gamma has a stimulative effect upon the metabolism of hatched chicks.

To comprehensively evaluate the effect of a short-term diabetes self-management education (DSME) on metabolic markers and atherosclerotic parameters in patients with type 2 diabetes. 76 patients with type 2 diabetes were recruited in this study. They were divided into the intervention group (n = 36) and control group (n = 40). The patients in the intervention group received a 3-month intervention, including an 8-week education on self-management of diabetes mellitus and subsequent 4 weeks of practice of the self-management guidelines. The patients in the control group received standard advice on medical nutrition therapy. Metabolic markers, carotid intima-media thickness (CIMT), and carotid arterial stiffness (CAS) of the patients in both groups were assessed before and after the 3-month intervention. There was a significant reduction in hemoglobin A1c (HbA1c, -0.2 ± 0.56% versus 0.08 ± 0.741%; P < 0.05) and body weight (-1.19 ± 1.39 kg versus -0.61 ± 2.04 kg; P < 0.05) in the intervention group as compared to the control group. However, no significant improvements were found in other metabolic markers, CIMT and CAS (P > 0.05). DSME can improve HbA1c and body weight in patients with type 2 diabetes.

Both men and women are vulnerable to weight gain during the college years, and this phenomenon is linked to an increased risk of several chronic diseases and mortality. Technology represents an attractive medium for the delivery of weight control interventions focused on college students, given its reach and appeal among this population. However, few technology-mediated weight gain prevention interventions have been evaluated for college students. This study examined a new technology-based, social media-facilitated weight gain prevention intervention for college students. Undergraduates (n =58) in two sections of a public university course were allocated to either a behavioral weight gain prevention intervention (Healthy Weight, HW; N=29) or a human papillomavirus (HPV) vaccination awareness intervention (control; N=29). All students were enrolled, regardless of initial body weight or expressed interest in weight management. The interventions delivered 8 lessons via electronic newsletters and Facebook postings over 9 weeks, which were designed to foster social support and introduce relevant educational content. The HW intervention targeted behavioral strategies to prevent weight gain and provided participants with a Wi-Fi-enabled scale and an electronic physical activity tracker to facilitate weight regulation. A repeated-measures analysis of variance was conducted to examine within- and between-group differences in measures of self-reported weight control practices and objectively measured weight. Use of each intervention medium and device was objectively tracked, and intervention satisfaction measures were obtained. Students remained weight stable (HW: -0.48+1.9 kg; control: -0.45+1.4 kg), with no significant difference between groups over 9 weeks (P =.94). However, HW students reported a significantly greater increase in the number of appropriate weight control strategies than did controls (2.1+4.5 vs -1.1+3.4, respectively; P =.003) and there was no increase in inappropriate weight control behaviors (P =.11). More than 90% of students in the HW arm opened the electronic newsletters each week, and the average number of Facebook interactions (comments and likes) per student each week was 3.3+1.4. Each self-monitoring device was initialized by 90% of HW students. On average, they used their physical activity tracker for 23.7+15.2 days and their Wi-Fi scale for 14.1+13.1 days over the 9 weeks. HW students rated the intervention favorably. The short-term effect of this technology-based weight gain prevention intervention for college students is promising and merits evaluation over a longer duration to determine whether engagement and behavioral improvements positively affect weight outcomes and can be maintained.

To determine the effect of partial Kangaroo Mother Care (KMC) on growth rates and duration of hospital stay of Low Birth Weight (LBW) infants. Unblinded, randomised clinical controlled trial. Kenyatta National Hospital, Nairobi, Kenya. Over a nine month period, consecutive recruitment of eligible LBW infants weighing 1000 g to 1750 g was done until a sample of 166 infants was reached. Kangaroo mother care was practised over an eight hour period per day for the intervention group while the controls remained in incubators or cots. Weight, head circumference, and mid upper arm circumference were monitored for all infants till discharge at 1800 g. Of the 166 infants recruited 157 were followed up to discharge. Baseline characteristics were similar for the two groups except for mother's age, with the KMC group mothers having a mean age of 26.5 years while the control group mothers had a mean age of 24 years, (p = 0.04). The KMC group had significantly higher growth rates as shown by the higher mean weight gain of 22.5 g/kg/day compared with 16.7g/kg/day for the control group, (p < 0.001); higher mean head circumference gain of 0.91 cm/week compared with 0.54 cm/week for the control group, (p < 0.001) and higher mean mid upper arm circumference gain of 0.76 cm/week compared with 0.48 cm/week for the control group, (p = 0.002). Although overall duration of stay was similar between study arms, when infants were stratified into those above or below 1500 g KMC infants' duration of stay was significantly shorter than those in regular care. Using logistic regression, KMCwas the strongest predictor formeanweight, meanhead circumference and mean MUAC gain while mother's age (older) was the strongest predictor for mean duration of stay with KMC being an independent predictor of duration of stay. Low birth weight infants in this cohort achieved rates of growth within the recommended intrauterine growth but babies managed using partial KMC grew faster and were thus discharged earlier than those on standard of care. Since partial KMC was beneficial, it should be fully implemented for all eligible infants.

Weight gain accompanies smoking cessation, but dieting during quitting is controversial as hunger may increase urges to smoke. This is a feasibility trial for the investigation of a very low calorie diet (VLCD), individual modest energy restriction, and usual advice on hunger, ketosis, urges to smoke, abstinence and weight gain in overweight smokers trying to quit. This is a 3 armed, unblinded, randomized controlled trial in overweight (BMI > 25 kg/m2), daily smokers (CO > 10 ppm); with at least 30 participants in each group. Each group receives identical behavioural support and NRT patches (25 mg(8 weeks),15 mg(2 weeks),10 mg(2 weeks)). The VLCD group receive a 429-559 kcal/day liquid formula beginning 1 week before quitting and continuing for 4 weeks afterwards. The modest energy restricted group (termed individual dietary and activity planning(IDAP)) engage in goal-setting and receive an energy prescription based on individual basal metabolic rate(BMR) aiming for daily reduction of 600 kcal. The control group receive usual dietary advice that accompanies smoking cessation i.e. avoiding feeling hungry but eating healthy snacks. After this, the VLCD participants receive IDAP to provide support for changing eating habits in the longer term; the IDAP group continues receiving this support. The control group receive IDAP 8 weeks after quitting. This allows us to compare IDAP following a successful quit attempt with dieting concurrently during quitting. It also aims to prevent attrition in the unblinded, control group by meeting their need for weight management. Follow-up occurs at 6 and 12 months.Outcome measures include participant acceptability, measured qualitatively by semi-structured interviewing and quantitatively by recruitment and attrition rates. Feasibility of running the trial within primary care is measured by interview and questionnaire of the treatment providers. Adherence to the VLCD is verified by the presence of urinary ketones measured weekly. Daily urges to smoke, hunger and withdrawal are measured using the Mood and Physical Symptoms Scale-Combined (MPSS-C) and a Hunger Craving Score (HCS). 24 hour, 7 day point prevalence and 4-week prolonged abstinence (Russell Standard) is confirmed by CO < 10 ppm. Weight, waist and hip circumference and percentage body fat are measured at each visit. Current controlled trials ISRCTN83865809.

Aim This study assessed weight and height changes among underweight children who received a locally produced, cereal-based, ready-to-use supplementary food. Methods We recruited 500 underweight Bangladeshi children aged 6–23 months from a Dhaka slum and individually matched them by sex and neighbourhood with 480 well-nourished controls. The intervention group received the daily food supplement for five months and both groups received daily micronutrient supplements. Their weight, height, mid-upper-arm circumference and head circumference were measured monthly. Results The children’s mean daily weight gain decreased from 1.27 to 0.66 grams per kilogram per day (g/kg/day) in the intervention group and 0.77 to 0.49 g/kg/day in the controls after adjusting for age differences between the two groups from baseline to five months of follow up. The mean monthly height gain decreased from 1.13 to 1.03 millimeters per metre per month in the intervention children and 1.26 to 1.01 in the controls. The weight gain was highest in the intervention children who were most wasted at baseline and the controls who were least stunted. Conclusion The children showed suboptimal growth despite food supplements, highlighting the need for ongoing research to develop inexpensive, locally-sourced food supplements to improve the nutrition of underweight children in Bangladesh.

Intervention studies of developmental care for preterm infants in Western societies have shown early but unsustainable effects on child outcomes, however only a limited of studies have examined if developmental care interventions produce similar effects in Eastern cultural contexts. To examine the effectiveness of in-hospital developmental care on neonatal morbidity, growth and development of preterm infants with very low birth weight (VLBW; birth weight<1500 g) in Taiwan. One hundred and seventy-eight VLBW preterm infants were randomly assigned to the clinical trial during hospitalization at three hospitals in Taiwan; the control group received five sessions of standard child-focused developmental care and the intervention group received five sessions of child- and parent-focused developmental care. Sixty-two normal term infants were also included as a comparison group. Infants were examined for morbidity, growth and developmental outcomes at term age. At study entry, more infants in the intervention group were twins or multiples than those in the control group (29% vs. 16%, p=0.05). After adjusting for birth set, the intervention group had lower incidences of stage II-III retinopathy (odds ratio [OR]=0.34 [95% confidence interval (CI): 0.15-0.79]; p=0.01) and feeding desaturation (OR=0.32 [95% CI: 0.10-1.00]; p=0.05) and had greater daily weight gains (difference=2.0 g/day [95% CI: 0-4.0 g/day]; p=0.05) as compared with the control group. However, the intervention and control groups did not differ in any of the neurodevelopmental measures. In-hospital developmental care has short-term benefits for Taiwanese VLBW preterm infants in reducing the risk of retinopathy and feeding desaturation as well as in enhancing weight gains at term age.

The elemental diet (ED) Elental® reportedly reduces adverse reactions to chemotherapy in digestive system cancer patients; however, the mechanism is unclear. Therefore, we verified the protective effect of ED against gastrointestinal disorders induced by the antineoplastic drug 5-fluorouracil (5-FU). After 5 days of tail vein injections of 40 mg/kg/day 5-FU in female BALB/c mice, the mice were given oral ED (ED group) or dextrin with the same number of calories (control group). We measured the weight of salivary glands and the PAS-positive area of colonic mucosa and verified the antitumor effect in tumor-bearing mice given 5-FU and ED. Although body weight decreased after 5-FU treatment, ED group mice weighed more than control group mice. Additionally, although control mice developed diarrhea after 5-FU treatment, the ED group showed only loose stools. The control group saliva volume was approximately one sixth of the vehicle group volume after 5-FU treatment; this was improved to approximately half in the ED group. The area ratio of PAS-positive cells in the colonic mucosa was reduced by 5-FU treatment, with the ratio being higher in the ED group than that in the control group. Similar tumor growth suppression was observed in the 5-FU and ED groups. ED alleviated adverse reactions to 5-FU without affecting antitumor activity. Protection against 5-FU-induced weight loss was potentially due to both improved nutritional support with combined ingredients and prevention of diarrhea that is associated with reduced colonic goblet cells and decreased saliva production from reduced salivary gland contraction.

To identify the relationship and behaviour of the variables of self-control, self-efficacy and locus control in weight regulation of obese, overweight and normal weight adults. Transversal study undertaken in the Health Centre of El Coto (Gijón) from 1st April to 30th July 2015. Subjects between 18-65 years of age with a body mass index recording within the last two years. serious medical illness, eating disorders or pregnant women. Behavioural variables: self-regulation of body weight (Inventory of self-control of body weight), perceived self-efficacy in weight regulation (Inventory of perceived self-efficacy in weight regulation) and locus control in weight regulation (Inventory of locus control in weight regulation). Anthropometric variables: weight (kg) and height (m), body mass index. One hundred and six participants were included: 32 were obese, 28 overweight and 46 normal weight. Significant differences were found between the 3 study groups for total scale of self-efficacy (F=61.77; p<.01), total scale of self-regulation (F=45.97; p<.01), internal locus control (F=13.92; p=.019), other weighty influences of locus control (F=9.21; p<.01) and random locus control (F=3.50; p=.011). The relationship between body mass index and behavioural variables of self-efficacy, self-regulation and locus control, suggests the need for healthcare professionals to include psychological factors of behaviour in any preventive action and intervention directed at weight control.

Obesity is associated with significant morbidity and mortality rates. Even modest weight loss may be associated with health benefits. Alpha-lipoic acid (ALA) is a naturally occurring antioxidant. Studies have suggested anti-obesity properties of ALA; however, results are inconsistent. The purpose of this study is to conduct a meta-analysis of the effect of ALA on weight and body mass index (BMI). A comprehensive, systematic literature search identified 10 articles on randomized, double-blind, placebo-controlled studies involving ALA. We conducted a meta-analysis of mean weight and BMI change differences between ALA and placebo treatment groups. Alpha-lipoic acid treatment coincided with a statistically significant 1.27 kg (confidence interval = 0.25 to 2.29) greater mean weight loss compared with the placebo group. A significant overall mean BMI difference of -0.43 kg/ m 2 (confidence interval = -0.82 to -0.03) was found between the ALA and placebo groups. Meta-regression analysis showed no significance in ALA dose on BMI and weight changes. Study duration significantly affected BMI change, but not weight change. Alpha-lipoic acid treatment showed small, yet significant short-term weight loss compared with placebo. Further research is needed to examine the effect of different doses and the long-term benefits of ALA on weight management. © 2017 World Obesity Federation.

Heat stress is one of the major causes of a decreased performance of laying quail in tropical and subtropical countries. The aim of this study was to investigate the impact of temperature humidity index (THI) on fertility aspects, external and internal egg quality parameters in Japanese quail. One hundred and forty four (144) Japanese quail, 12 of weeks age, were used. Birds were divided randomly into three equal groups, control (at low THI, lower than 70), H 1 (at moderate THI, 70-75) and H 2 (at high THI, 76-80). Quail in the control and H 1 groups had significant greater fertility (p=0.021) and hatchability % (p=0.037), compared with H 2 group. Quail in the control group (at low THI) laid heavier egg weight with a higher external (egg weight (p=0.03), shell thickness, shell weight, eggshell ratio and eggshell density (p=0.001)) and internal egg quality score (albumin weight (p=0.026), yolk height (p=0.003), yolk index (p=0.039) and Haugh unit (p=0.001)). Otherwise, such quality traits were compromised in heat-stressed quail. At the high THI level, egg weight had a significant positive correlation with albumin weight (r=0.58, p<0.01), yolk weight (r=0.22, p<0.05), albumen ratio (r=0.17, p<0.05), yolk height (r=0.14, p<0.05) and yolk index (r=0.18, p<0.05), but was negatively correlated with yolk ratio (r=-0.15, p<0.05). Japanese quail exposed to heat stress (THI over 75) revealed drop in fertility indices and egg quality traits, indicating a detrimental policy of economic income. Copyright © 2016 Elsevier Ltd.

Whole grain sorghum is a promising ingredient in foods, especially those targeting satiety and weight control. This study aimed to test weight loss effects of a whole grain red sorghum product incorporated into an energy-restricted diet. Sixty subjects (46 females) were randomized to either a sorghum (intervention) or white wheat (control) group, receiving 45 g of flaked cereal biscuits to include daily in their prescribed diets for 12 weeks. Primary outcome was weight loss. Secondary outcomes included plasma glucose, glycosylated hemoglobin (HbA1c), insulin, total cholesterol, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), triacylglycerides (TAG), interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor alpha (TNF-α), high-sensitivity C-reactive protein (hs-CRP), and total antioxidant capacity (TAC; measured at 0 and 12 weeks). After 12 weeks, there were no significant differences in weight loss or any clinical variables between a wheat control and sorghum cereal group in an energy-restricted diet. Equivalent amounts of weight were lost (p = 0.369) in both groups, and the majority of clinical indices such as fasting glucose, insulin, cholesterol, and key inflammatory biomarkers showed significant beneficial changes over time (p < 0.05). Although both groups experienced significant weight loss and general improvement in a number of clinical measures, no effects appeared specifically related to sorghum consumption. Further clinical trials are necessary to establish an evidence base for weight loss effects from chronic sorghum intake. Sorghum represents a viable, gluten-free grain alternative in the formulation of novel food products.

To our knowledge, no meta-analysis to date has assessed the efficacy of mobile phone apps to promote weight loss and increase physical activity. To perform a systematic review and meta-analysis of studies to compare the efficacy of mobile phone apps compared with other approaches to promote weight loss and increase physical activity. We conducted a systematic review and meta-analysis of relevant studies identified by a search of PubMed, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus from their inception through to August 2015. Two members of the study team (EG-F, GF-M) independently screened studies for inclusion criteria and extracted data. We included all controlled studies that assessed a mobile phone app intervention with weight-related health measures (ie, body weight, body mass index, or waist circumference) or physical activity outcomes. Net change estimates comparing the intervention group with the control group were pooled across studies using random-effects models. We included 12 articles in this systematic review and meta-analysis. Compared with the control group, use of a mobile phone app was associated with significant changes in body weight (kg) and body mass index (kg/m(2)) of -1.04 kg (95% CI -1.75 to -0.34; I2 = 41%) and -0.43 kg/m(2) (95% CI -0.74 to -0.13; I2 = 50%), respectively. Moreover, a nonsignificant difference in physical activity was observed between the two groups (standardized mean difference 0.40, 95% CI -0.07 to 0.87; I2 = 93%). These findings were remarkably robust in the sensitivity analysis. No publication bias was shown. Evidence from this study shows that mobile phone app-based interventions may be useful tools for weight loss.

Oligofructose is a prebiotic dietary fibre obtained from chicory root inulin. Oligofructose supplementation may affect satiety, food intake, body weight and/or body composition. The aim was to examine the efficacy of oligofructose-supplemented granola bars on the following weight management outcomes: satiety, energy intake, body weight and body composition in overweight or obese adults. In all, fifty-five adults with overweight or obesity (thirty-six females/nineteen males; age: 41 (sd 12) years; 90·6 (sd 11·8) kg; BMI: 29·4 (sd 2·6) kg/m2) participated in a parallel, triple-blind, placebo-controlled intervention. A total of twenty-nine subjects replaced their snacks twice a day with an equienergetic granola bar supplemented with 8 g of oligofructose (OF-Bar). Subjects in the control group (n 26) replaced their snack with a control granola bar without added oligofructose (Co-Bar). Satiety, 24-h energy intake, body weight and body composition (fat mass and waist circumference) were measured at baseline, weeks 6 and 12. In addition, weekly appetite and gastrointestinal side effects were measured. During the intervention, energy intake, body weight and fat mass remained similar in the Co-Bar and OF-Bar groups (all P>0·05). Both groups lost 0·3 (sd 1·2) kg lean mass (P<0·01) and reduced their waist circumference with -2·2 (sd 3·6) cm (P<0·0001) after 12 weeks. The OF-Bar group reported decreased hunger in later weeks of the intervention (P=0·04), less prospective food consumption (P=0·03) and less thirst (P=0·003). To conclude, replacing daily snacks for 12 weeks with oligofructose-supplemented granola bars does not differentially affect energy intake, body weight and body composition compared with a control bar. However, there was an indication that appetite was lower after oligofructose bar consumption.

Purpose The purpose of the study was to evaluate the feasibility of integrating Community Health Workers (CHWs) as part of the team leading diabetes group visits. Methods This was a randomized controlled study that integrated CHWs as part of the team leading diabetes group visits for low-income Hispanic adults (n = 50). Group visits met for 3 hours each month for a 6-month duration. Main measures included baseline and 6-month clinical outcomes (ie, A1C, lipids), concordance with 8 standard of care guidelines (ie, screens for cervical, breast, and colon cancer) from the US Preventive Task Force and American Diabetes Association, and participant acceptability. Results Compared to control participants, the intervention group resulted in significantly better clinical outcomes or guideline concordance for the following areas: target A1C levels, retinal eye exams, diabetes foot exams, mammograms, and urine microalbumin. Significantly more individuals in the control group gained weight, whereas a greater number of participants in the intervention group lost weight. Intervention participants found the group visits highly acceptable. Conclusions Integrating CHWs as part a comprehensive diabetes group visit program is a feasible and effective system-level intervention to improve glycemic control and achieve guideline concordance.

Low birth weight (LBW, < 2500 g) affects one third of newborn infants in rural south Asia and compromises child survival, infant growth, educational performance and economic prospects. We aimed to assess the impact on birth weight and weight-for-age Z-score in children aged 0-16 months of a nutrition Participatory Learning and Action behaviour change strategy (PLA) for pregnant women through women's groups, with or without unconditional transfers of food or cash to pregnant women in two districts of southern Nepal. The study is a cluster randomised controlled trial (non-blinded). PLA comprises women's groups that discuss, and form strategies about, nutrition in pregnancy, low birth weight and hygiene. Women receive up to 7 monthly transfers per pregnancy: cash is NPR 750 (~US$7) and food is 10 kg of fortified sweetened wheat-soya Super Cereal per month. The unit of randomisation is a rural village development committee (VDC) cluster (population 4000-9200, mean 6150) in southern Dhanusha or Mahottari districts. 80 VDCs are randomised to four arms using a participatory 'tombola' method. Twenty clusters each receive: PLA; PLA plus food; PLA plus cash; and standard care (control). Participants are (mostly Maithili-speaking) pregnant women identified from 8 weeks' gestation onwards, and their infants (target sample size 8880 birth weights). After pregnancy verification, mothers may be followed up in early and late pregnancy, within 72 h, after 42 days and within 22 months of birth. Outcomes pertain to the individual level. Primary outcomes include birth weight within 72 h of birth and infant weight-for-age Z-score measured cross-sectionally on children born of the study. Secondary outcomes include prevalence of LBW, eating behaviour and weight during pregnancy, maternal and newborn illness, preterm delivery, miscarriage, stillbirth or neonatal mortality, infant Z-scores for length-for-age and weight-for-length, head circumference, and postnatal maternal BMI and mid-upper arm circumference. Exposure to women's groups, food or cash transfers, home visits, and group interventions are measured. Determining the relative importance to birth weight and early childhood nutrition of adding food or cash transfers to PLA women's groups will inform design of nutrition interventions in pregnancy.

This study investigated the impact of 2 coccidiosis control systems (vaccine vs anticoccidial) and 2 feeding plans (standard energy vs low energy content, the latter supplemented with threonine and enzymes in the second half of the production cycle) on white striping (WS) prevalence and severity in chicken broiler breasts at commercial slaughter age (51 d). The age of lesion onset was also investigated with the sacrifice of 80 chicks at 12, and 80 chicks at 25 d of age. Seven hundred and twenty ROSS 708 strain male chicks were divided into 4 groups: a non-vaccinated group fed with standard diet (CONTROL); two groups vaccinated against coccidiosis but fed either a standard diet (VACC) or a low-energy diet supplemented with threonine and enzymes (VACC-LE plus); and a fourth group fed a standard diet containing anticoccidial additive except during the finishing period (COX). After live performance, yields, and fillet pH were measured, the breasts were weighed and scored as level 0 (no WS), level 1 (moderate WS), and level 2 (severe WS) at each of the 3 ages; data were covariate for slaughter weight. The results suggest an ameliorative effect of coccidiosis control systems when compared to the control group in terms of live weight, breast yield, and whole breast weight, with heavier fillets characterized by higher pH values. WS appeared at 25 d of age with an average prevalence of 11.5% and with lesions of moderate severity. There were no statistically significant differences due to the experimental treatment at this age. At commercial slaughter age, total average prevalence was 96%, with COX birds showing higher level 2 prevalence (77.6%). This could be related to the higher slaughter weight reached by the COX group (P<0.001) and the treatment effect (P<0.01) that probably adds to the effect of live weight. Diet had no effect on overall live performance of VACC-LE plus chickens, which were similar to those of the VACC group. © 2015 Poultry Science Association Inc.

Background Young adults display substantial weight gain. Preventing this age-related weight gain would reduce overweight and obesity. Objective We evaluated an internet based intervention using Internet-connected scales and graphic email feedback; the Caloric Titration Method (CTM), to reduce age-related weight gain over the course of 1 y among first-year college students. Design First-year college students (n=167) were randomized to (CTM) or control (C) group. Both groups were provided Internet-connected scales. CTM group was instructed to weigh daily, view a weight graph emailed to them after weighing, and try to maintain their weight as indicated in the graph. The C group could weigh at any time, but did not receive feedback. At six months and 1 year the C group were notified to provide weights. Intention to treat analysis, using a mixed model adjusted for baseline weight, BMI and gender was used to analyze the effect of the intervention. Results Baseline Body Mass Index was 22.9 ± 3.0 kg/m2. Frequency of self-weighing (median) was 5 times/week in the CTM group, compared to 1 time/week in C (p<0.001). Ninety-five percent of the CTM participants weighed ≥3 times/week, compared to 15% in C group (p<0.001). After 1 year the C group had gained 1.1 ± 4.4 kg whereas the CTM group lost 0.5 ± 3.7 kg, yielding a significant overall time*group interaction (F=3.39, p=0.035). The difference in weight change between the two groups at 1 year was significant (p=0.004). Weight change of the CTM group was not different from zero whereas weight gain in C group was significant. Retention was 81%. Conclusions The internet based frequent self-weighing CTM system was effective in preventing age-related weight gain in young adults over one year and thus offers promise to reduce overweight and obesity.

Objective To observe the combination effect of doxorubicin and Citrus hystrix (kaffir lime's) peel ethanolic extract (ChEE) on blood serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity and cardio-hepato-histopathology of female Sprague Dawley rats. Methods Doxorubicin and ChEE (5 rats per group) were administered in five groups of 3 rats each for 11 d. Group I: doxorubicin (dox) 4.67 mg/kg body weight; Group II: dox+ChEE 500 mg/kg body weight; Group III: dox+ChEE 1 000 mg/kg body weight; Group IV: ChEE 1 000 mg/kg body weight; Group V: untreated (control). Results ChEE repaired cardiohistopathology profile of doxorubicin induced cardiotoxicity and hepatotoxicity rats, but did not repair neither hepatohistopathology profile nor reduce serum activity of ALT and AST. Conclusion ChEE has potency to be developed as cardioprotector agent in chemotherapy. PMID:23646300

Bariatric surgery is currently the most effective therapy to induce weight loss in morbidly obese patients. Objective. This controlled, clinical trial with a two-year intervention was aimed at comparing the efficacy of two nonsurgical approaches versus bariatric surgery, on body weight changes and metabolic parameters in morbidly obese patients. Methods. Patients were randomized to an Intensive Lifestyle Intervention (ILI) (n = 60) or Conventional Obesity Therapy (COT) (n = 46). The ILI group received behavioral therapy and nutritional counseling. The COT group received standard medical treatment. They were compared with a third group, Surgical Obesity Group (SOG) (n = 37). Results. Patients who received ILI had a greater percentage of weight loss than patients receiving COT (−11.3% versus −1.6%; p < 0.0044). Interestingly 31.4% of patients included in the ILI group were no longer morbidly obese after just six months of intervention, increasing to 44.4% after 24 months of intervention. The percentage weight loss in SOG was −29.6% after that same period of time. Conclusions. ILI was associated with significant weight loss when compared to COT, in a group of patients with obesity. An ILI approach could be an alternative therapy to patients with obesity, who are not candidates to undergo bariatric surgery. This trial is registered with EudraCT 2009-013737-24. PMID:26257780

To investigate the efficacy of water preloading before meals as a weight loss strategy for adults with obesity. A two-group randomized controlled trial was conducted in Birmingham, England. Eighty-four adults with obesity were recruited from general practices. All participants were given a face-to-face weight management consultation at baseline (30 min) and a follow-up telephone consultation at 2 weeks (10 min). At baseline, participants were randomized to either drinking 500 ml of water 30 min before their main meals or an attention control group where participants were asked to imagine their stomach was full before meals. The primary outcome was weight change at 12-week follow-up. Several measures of adherence were also used, including 24 h total urine collections. 41 participants were randomized to the intervention group and 43 to the comparator group. The water preloading group lost -1.3 kg (95% CI -2.4 to -0.1, P = 0.028) more than comparators at follow up. Adjusting for ethnicity, deprivation, age, and gender resulted in the intervention group losing -1.2 kg (95% CI -2.4 to 0.07, P = 0.063) more than the comparator. There is preliminary evidence that water preloading before main meals leads to a moderate weight loss at follow up. ISRCTN33238158. © 2015 The Obesity Society.

A reduction of visceral fat is important for improvement of metabolic risk. This study was designed to compare the effects of a web-based program alone or together with measurement and self-awareness of accumulated visceral fat in Japanese workers. A new noninvasive device to measure visceral fat accumulation was introduced, and efficacy on weight-loss and improvement of healthy behaviors were examined. This study was conducted according to Helsinki declaration and approved by the ethical committee of Japan Hospital Organization, National Kyoto Hospital. Two-hundred and sixteen overweight and obese males with BMI of more than 23 participated from 8 healthcare offices of 3 Japanese private companies. Subjects were randomly allocated into control group, Web-based weight-loss program (Web), or Web + Visceral fat measurement group (Web + VFA). Eighty-one percent of participants completed the study. Reductions of body weight, waist circumference, and BMI were the largest in Web + VFA group, and the differences between groups were significant by ANOVA. Improvements of healthy behaviors were the largest in Web + VFA group, and the differences of healthy eating improvement scores between Web + VFA and control groups were significant. Our findings suggest that measurement and awareness of visceral fat are effective in weight reduction in overweight and obese males in the workplace.

Background Intermittent severe energy restriction is popular for weight management. To investigate whether intermittent moderate energy restriction may improve this approach by enhancing weight loss efficiency, we conducted a study in mice, where energy intake can be controlled. Methods Male C57/Bl6 mice that had been rendered obese by an ad libitum diet high in fat and sugar for 22 weeks were then fed one of two energy-restricted normal chow diets for a 12-week weight loss phase. The continuous diet (CD) provided 82% of the energy intake of age-matched ad libitum chow-fed controls. The intermittent diet (ID) provided cycles of 82% of control intake for 5–6 consecutive days, and ad libitum intake for 1–3 days. Weight loss efficiency during this phase was calculated as (total weight change) ÷ [(total energy intake of mice on CD or ID)–(total average energy intake of controls)]. Subsets of mice then underwent a 3-week weight regain phase involving ad libitum re-feeding. Results Mice on the ID showed transient hyperphagia relative to controls during each 1–3-day ad libitum feeding period, and overall ate significantly more than CD mice (91.1±1.0 versus 82.2±0.5% of control intake respectively, n = 10, P<0.05). There were no significant differences between CD and ID groups at the end of the weight loss or weight regain phases with respect to body weight, fat mass, circulating glucose or insulin concentrations, or the insulin resistance index. Weight loss efficiency was significantly greater with ID than with CD (0.042±0.007 versus 0.018±0.001 g/kJ, n = 10, P<0.01). Mice on the CD exhibited significantly greater hypothalamic mRNA expression of proopiomelanocortin (POMC) relative to ID and control mice, with no differences in neuropeptide Y or agouti-related peptide mRNA expression between energy-restricted groups. Conclusion Intermittent moderate energy restriction may offer an advantage over continuous moderate energy restriction, because it induces significantly greater weight loss relative to energy deficit in mice.

Background The National Weight Control Registry (NWCR) was established to examine characteristics of successful weight loss maintainers. This study compares the diet and behavioral characteristics and weight regain trajectories of NWCR members with differing physical activity (PA) levels at baseline. Methods Participants (n=3591) were divided into 4 levels of self-reported PA at registry entry (<1000, 1000 to <2250, 2250 to <3500, and ≥3500 kcals/week). We compared self-reported energy intake (EI), macronutrient composition, eating behaviors (dietary restraint, hunger, and disinhibition), weight loss maintenance strategies, and 3 year weight regain between these 4 activity groups. Results Those with the highest PA at registry entry had lost the most weight, and reported lower fat intake, more dietary restraint, and greater reliance on several specific dietary strategies to maintain weight loss. Those in the lowest PA category maintained weight loss despite low levels of PA and without greater reliance on dietary strategies. There were no differences in odds of weight regain at year 3 between PA groups. Conclusions These findings suggest that there is not a “one size fits all strategy” for successful weight loss maintenance and that weight loss maintenance may require the use of more strategies by some individuals than others.

The susceptibility to type 2 diabetes of people of south Asian descent is established, but there is little trial-based evidence for interventions to tackle this problem. We assessed a weight control and physical activity intervention in south Asian individuals in the UK. We did this non-blinded trial in two National Health Service (NHS) regions in Scotland (UK). Between July 1, 2007, and Oct 31, 2009, we recruited men and women of Indian and Pakistani origin, aged 35 years or older, with waist circumference 90 cm or greater in men or 80 cm or greater in women, and with impaired glucose tolerance or impaired fasting glucose determined by oral glucose tolerance test. Families were randomised (using a random number generator program, with permuted blocks of random size, stratified by location [Edinburgh or Glasgow], ethnic group [Indian or Pakistani], and number of participants in the family [one vs more than one]) to intervention or control. Participants in the same family were not randomised separately. The intervention group received 15 visits from a dietitian over 3 years and the control group received four visits in the same period. The primary outcome was weight change at 3 years. Analysis was by modified intention to treat, excluding participants who died or were lost to follow-up. We used linear regression models to provide mean differences in baseline-adjusted weight at 3 years. This trial is registered, number ISRCTN25729565. Of 1319 people who were screened with an oral glucose tolerance test, 196 (15%) had impaired glucose tolerance or impaired fasting glucose and 171 entered the trial. Participants were in 156 family clusters that were randomised (78 families with 85 participants were allocated to intervention; 78 families with 86 participants were allocated to control). 167 (98%) participants in 152 families completed the trial. Mean weight loss in the intervention group was 1.13 kg (SD 4.12), compared with a mean weight gain of 0.51 kg (3.65) in the control group, an adjusted mean difference of -1.64 kg (95% CI -2.83 to -0.44). Modest, medium-term changes in weight are achievable as a component of lifestyle-change strategies, which might control or prevent adiposity-related diseases.

Preliminary results obtained in calves, lambs and goat kids infected by Cryptosporidium sp. have indicated a partial prophylactic efficacy of halofuginone lactate when administered at 100 μg/kg body weight (BW). In this study, the efficacy of halofuginone lactate was evaluated in goat neonates experimentally inoculated with Cryptosporidium parvum oocysts per oral route. The trial consisted in 2 replicated experiments carried out successively at 2 months of interval. Twenty-two 2- to 4-day-old kids were experimentally inoculated once, 2-3 days after the arrival in premises, with 10(6)C. parvum oocysts per oral route and were allocated into 2 groups. Animals of group 1 acted as untreated control whereas animals of group 2 received halofuginone lactate for 10 days from the infection day to day 9 post-infection (DPI) at a daily oral dose rate of 100 μg/kg BW. Individual oocyst shedding was monitored by daily examination of faecal smears stained by carbol fuchsin and scored semi-quantitatively (0-5) until 19 DPI. Daily diarrhoea scores, weight gain and mortality were recorded. In the first experiment, oocyst excretion started 1 DPI in the control group, was highest on 4 DPI (mean score 3.6) and became undetectable from 16-19 DPI. In the treated group, oocyst shedding started 1 day later, showed lower scores compared to control on 4, 5, 6, 7 and 10 DPI and vanished from 16 to 19 DPI. No significant difference was seen for weight gains between groups. Five kids died in the control group compared to 1 kid in the treated group. In the second (replicated) experiment, oocyst excretion started 2 DPI in the control group, was highest on 4 DPI (mean score 4.5) and became undetectable 18 and 19 DPI. In the treated group, oocyst shedding started 2 days later, peaked on 13 DPI (mean score 2.3) and persisted until the end of the experiment. No significant difference was seen for weight gains between groups. Ten kids died in the control group compared to 3 kids in the treated group. The results demonstrated the efficacy of halofuginone lactate when given as a prophylactic treatment at 100 μg/kg BW during 10 days in reducing oocyst shedding, diarrhoea and mortality in goat kid cryptosporidiosis.

Neuroscience evidence suggests that adolescent obesity is linked to brain dysfunctions associated with enhanced reward and somatosensory processing and reduced impulse control during food processing. Comparatively less is known about the role of more stable brain structural measures and their link to personality traits and neuropsychological factors on the presentation of adolescent obesity. Here we aimed to investigate regional brain anatomy in adolescents with excess weight vs. lean controls. We also aimed to contrast the associations between brain structure and personality and cognitive measures in both groups. Fifty-two adolescents (16 with normal weight and 36 with excess weight) were scanned using magnetic resonance imaging and completed the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), the UPPS-P scale, and the Stroop task. Voxel-based morphometry (VBM) was used to assess possible between-group differences in regional gray matter (GM) and to measure the putative differences in the way reward and punishment sensitivity, impulsivity and inhibitory control relate to regional GM volumes, which were analyzed using both region of interest (ROI) and whole brain analyses. The ROIs included areas involved in reward/somatosensory processing (striatum, somatosensory cortices) and motivation/impulse control (hippocampus, prefrontal cortex). Excess weight adolescents showed increased GM volume in the right hippocampus. Voxel-wise volumes of the second somatosensory cortex (SII) were correlated with reward sensitivity and positive urgency in lean controls, but this association was missed in excess weight adolescents. Moreover, Stroop performance correlated with dorsolateral prefrontal cortex volumes in controls but not in excess weight adolescents. Adolescents with excess weight have structural abnormalities in brain regions associated with somatosensory processing and motivation.

Background Weight bias is an important clinical issue that the educators of tomorrow's healthcare professionals cannot afford to ignore. This study, therefore, aimed to pilot a randomized controlled trial of the effects of educational films designed to reduce weight stigmatization toward obese patients on trainee dietitians’ and doctors’ attitudes. Methods A pre-post experimental design with a 6-week follow-up, which consisted of an intervention group (n = 22) and a control group (n = 21), was conducted to assess the efficacy of brief anti-stigma films in reducing weight bias, and to test whether future, larger-scale studies among trainee healthcare professionals are feasible. Results Participants at baseline demonstrated weight bias, on both implicit and explicit attitude measures, as well as strong beliefs that obesity is under a person's control. The intervention films significantly improved explicit attitudes and beliefs toward obese people, and participant evaluation was very positive. The intervention did not significantly improve implicit anti-fat bias. Conclusion The current study suggests both that it is possible to conduct a substantive trial of the effects of educational films designed to reduce weight stigma on a larger cohort of trainee healthcare professionals, and that brief educational interventions may be effective in reducing stigmatizing attitudes in this population.

A pre-post experimental design with a 6-week follow-up, which consisted of an intervention group (n = 22) and a control group (n = 21), was conducted to assess the efficacy of brief anti-stigma films in reducing weight bias, and to test whether future, larger-scale studies among trainee healthcare professionals are feasible. Participants at baseline demonstrated weight bias, on both implicit and explicit attitude measures, as well as strong beliefs that obesity is under a person's control. The intervention films significantly improved explicit attitudes and beliefs toward obese people, and participant evaluation was very positive. The intervention did not significantly improve implicit anti-fat bias. The current study suggests both that it is possible to conduct a substantive trial of the effects of educational films designed to reduce weight stigma on a larger cohort of trainee healthcare professionals, and that brief educational interventions may be effective in reducing stigmatizing attitudes in this population.

To determine the effect of a specific diabetes education class (Basics) on hemoglobin A1c values, weight, and systolic blood pressure. In this retrospective study, the researchers compared 2 groups of male veterans with a recent diagnosis of type 2 diabetes. One group received diabetes group education (n = 175) over a 4-month period, and the other received standard diabetes management follow-up (n = 184). Outpatient clinic setting in the Midwest. Basics class compared with standard level of care. Pre- and post-laboratory values for hemoglobin A1c, weight, and systolic blood pressure. Multivariate analysis of covariance and follow-up univariate statistics for significant differences. Findings revealed significant differences in hemoglobin A1c (P < .001) and weight (P < .001) in the treatment group compared with the control group. No significant difference was found in systolic blood pressure readings between the 2 groups. There was a significant difference in weight change between groups, with the treatment group demonstrating greater weight loss. There was an association between participation in the Basics diabetes education curriculum and reduction of hemoglobin A1c values. Some participants also had added benefit of significant weight loss.

Aim In Korea, obesity is more prevalent among men and lower socioeconomic groups. To explain this obesity disparity, we compared weight perception and weight control behavior across gender and socioeconomic status (SES). Methods We analyzed data from 16,260 participants aged 20 years or older in a nationally representative cross-sectional survey. SES indicators included education and income levels. Weight under-perception was defined when participants considered themselves lighter than their measured BMI status. Either no active or inappropriate weight control (i.e., trying to gain weight in obese individuals) was considered to be unhealthy patterns. Multivariate prevalence ratios were calculated using log-binomial regressions. Results Men had a higher prevalence of weight under-perception (24.5 vs. 11.9%) and unhealthy patterns of weight control behavior (57 vs. 40%) than women. Low education level was associated with weight under-perception (ptrend = 0.022 in men, ptrend ℋ 0.001 in women). Both education and income levels were significantly associated with patterns of weight control behavior (for education: ptrend ℋ 0.001 in men and women; for income: ptrend = 0.047 in men, ptrend ℋ 0.001 in women). Conclusion Weight perception and weight control behavior significantly varied by gender and SES. Public actions should be directed toward improving perception and behavior of high-risk populations.

Intensive treatment (INT) of type 1 diabetes reduces the incidence of cardiovascular disease (CVD) events compared with conventional treatment (CONV), but it also results in more weight gain. Our objective was to examine whether excessive weight gain from INT of type 1 diabetes is independently associated with subsequent CVD events. Quartiles (Q) of weight gain in 1,213 participants aged 18 years and older at enrollment in the Diabetes Control and Complications Trial (DCCT) were determined within randomized treatment groups (INT vs. CONV) using change in BMI from baseline to the closeout DCCT visits. Effects of this weight gain on CVD risk factors and outcomes during an additional 20 years of observational follow-up were then determined. The Q4 INT group experienced greater proportional weight gain (median change in BMI, 6.08 kg/m 2 ), increases in CVD risk factors, and need for medications for hypertension and lipids compared with the Q1-3 INT and comparable CONV groups. Over a mean of 26 years of follow-up, the numbers of major and total CVD events were not statistically different in Q4 compared with Q1-3 of either the INT or CONV group. By year 14, however, the incident CVD event curve became significantly higher in the Q4 INT group than in the Q1-3 INT groups ( P = 0.024) and was similar to that for the CONV group. For the first 13 years after DCCT, INT for type 1 diabetes reduced macrovascular events compared with CONV, even when excessive weight gain occurred. After this, total CVD events significantly increased in the Q4 INT group, becoming equivalent to those in the CONV group. Longer follow-up is needed to determine whether this trend continues and results in more major CVD events. © 2017 by the American Diabetes Association.

To determine (1) the most effective of three treatment approaches to retrain seated weight distribution long-term after stroke and (2) whether improvements could be generalized to weight distribution in standing. Inpatient rehabilitation unit. Forty asymmetrical acute stroke subjects were randomly allocated to one of four groups in this pilot study. Changes in weight distribution were compared between the 10 subjects of each of three treatment groups (task-specific reach, Bobath, or Balance Performance Monitor [BPM] feedback training) and a no specific treatment control group. One week of measurement only was followed by two weeks of daily training sessions with the treatment to which the subject was randomly allocated. Measurements were performed using the BPM daily before treatment sessions, two weeks after cessation of treatment and 12 weeks post study. Weight distribution was calculated in terms of mean balance (percentage of total body weight) or the mean of 300 balance points over a 30-s data run. In the short term, the Bobath approach was the most effective treatment for retraining sitting symmetry after stroke (p = 0.004). Training with the BPM and no training were also significant (p = 0.038 and p = 0.035 respectively) and task-specific reach training failed to reach significance (p = 0.26). At 12 weeks post study 83% of the BPM training group, 38% of the task-specific reach group, 29% of the Bobath group and 0% of the untrained group were found to be distributing their weight to both sides. Some generalization of symmetry training in sitting to standing was noted in the BPM training group which appeared to persist long term. Results should be treated with caution due to the small group sizes. However, these preliminary findings suggest that it might be possible to restore postural symmetry in sitting in the early stages of rehabilitation with therapy that focuses on creating an awareness of body position.

Objective To examine the relationship between parent feeding practices (restriction, monitoring, pressure to eat), general parenting behaviors (acceptance, psychological control, firm control), and aberrant child eating behaviors (emotional eating and excessive snacking) among overweight and normal weight children. Methods Overweight and normal weight children between 8 and 12 years old and their mothers (n=79 parent-child dyads) participated in this study. Mothers completed surveys on parent feeding practices (Child Feeding Questionnaire) and child eating behaviors (Family Eating and Activity Habits Questionnaire). Children reported on their mothers’ general parenting behaviors (Child Report of Parent Behavior Inventory). Parent and child height and weight were measured and demographic characteristics assessed. Logistic regression models, stratified by child weight status and adjusting for parent BMI, were used to determine which parenting dimensions and feeding practices were associated with child emotional eating and snacking behavior. Results Overweight children displayed significantly more emotional eating and excessive snacking behavior than normal weight children. Mothers of overweight children used more restrictive feeding practices and psychological control. Restrictive feeding practices were associated with emotional eating in the overweight group (OR = 1.26, 95% CI, 1.02, 1.56) and excessive snacking behavior in the normal weight group (OR = 1.13, 95% CI, 1.01, 1.26). When examining general parenting, firm control was associated with decreased odds of excessive snacking in the overweight group (OR=0.51, 95% CI, 0.28, 0.93). Conclusion Restrictive feeding practices were associated with aberrant child eating behaviors in both normal weight and overweight children. Firm general parenting however, was associated with decreased snacking behavior among overweight children. Longitudinal studies following children from infancy are needed to better understand the direction of these relationships. PMID:25370704

The aim of our study was to examine the changes in hypertransaminasemia after weight reduction in obese patients with and without NAFLD and the relation with insulin resistance. A population of 162 obese patients was randomly allocated to two groups: a) diet I (low fat) and b) diet II (low carbohydrate), dieting along 3 months. Patients were classified as group I (n=112) when serum ALT activity was normal or group II (NAFLD, n=30) when serum ALT activity was (>or=43 UI/L). In control group with diet I, BMI, weight, fat mass, waist to hip ratio, waist circumference, systolic pressure, total cholesterol, LDL cholesterol, HOMA and insulin levels decreased. In NAFLD group with diet I improved the same parameters and glucose, triglycerides, ALT, AST, gamaglutamine transferase levels, too. In control group with diet II, BMI, weight, fat mass, waist to hip ratio, waist circumference, systolic pressure, total cholesterol, LDL cholesterol, HOMA and insulin levels decreased. In NAFLD group with diet II improved the same parameters and glucose, triglycerides, ALT and gamaglutamine transferase levels, without statistical changes in AST. We showed that weight reduction secondary to two hypocaloric diets was associated with improvement in hipertransaminasemia and insulin resistance in NAFLD patients.

To identify the early warning signs of severe preeclampsia (SPE). A case-control (1:2) observational study was conducted. Forty-seven pregnant women with SPE, who attended the prenatal clinics of Peking University Third Hospital regularly from Jan. 2002 to Dec. 2007, were selected as the study group, including 12 early onset and 35 late onset ones. The control group consisted of 94 healthy singleton pregnant women at the same period. Clinical data were collected and analyzed. (1) The basal body mass index (BMI) showed no difference between the study and control group [(23.27 +/- 4.31) kg/m(2) vs (21.52 +/- 3.09) kg/m(2), P > 0.05]. (2) The net increase of BMI in the study group before the onset of SPE was higher than that in the control [(5.60 +/- 2.17) kg/m(2) vs (4.85 +/- 1.52) kg/m(2), P < 0.05] and the increase of BMI per week was also higher [(0.74 +/- 0.41) kg/(m(2).w)(-1) vs (0.23 +/- 0.18) kg/(m(2).w)(-1), P < 0.01]. The sensitivity and specificity of BMI increase per week in predicting SPE was 84% and 81% at a cut-off value of 0.39 kg/(m(2).w)(-1), respectively, and 79% and 91% at 0.41 kg/(m(2).w)(-1) correspondingly. (3) During the third trimester and before the onset of SPE, the weight gain per week in the study group was higher than that of the control [(0.93 +/- 0.70) kg vs (0.63 +/- 0.20) kg, P < 0.01]. Significant difference was also found in the net weight gain between the two groups (P < 0.01), but not in the percentage of women with excessive weight gain (> 0.50 kg/w) [60% (25/42) in the study group vs 63% (53/84) in the control group, P > 0.05]. (4) Higher percentage of women experienced pre-hypertension in the study group than in the controls [17% (8/47) vs 5% (5/94), P < 0.01]. (5) In the study group, 53% (25/47) of the women had edema before SPE onset, but the figure dropped to 18% (17/94) in the controls (P < 0.01). (6) Eight women in the study group and one in the control group suffered from hypoproteinemia before SPE onset with the average level of plasma albumin of (32.6 +/- 1.6) g/L and (38.4 +/- 2.1) g/L (P < 0.01), respectively. (7) Proteinuria was reported in 10 cases (21%) in the study group and 4 (4%) in the controls (P < 0.01). (8) Logistic regression analysis showed that the risk factors for SPE included edema (OR = 6.16, 95%CI: 2.29 - 16.57), pre-hypertension (OR = 6.21, 95%CI: 1.56 - 24.77), proteinuria (OR = 9.68, 95%CI: 1.86 - 50.30), and weight gain > 0.85 kg/w during the third trimester (OR = 11.60, 95%CI: 3.54 - 37.97). Edema, excessive weight gain, pre-hypertension and hypoproteinemia are early warning signs of SPE. Pregnant women with the above signs required close monitoring during prenatal care.

Objective Obesity is related to increased risk of several health complications, including depression. Many studies have reported improvements in mood with weight loss, but results have been equivocal. The present meta-analysis examined changes in symptoms of depression that were reported in trials of weight loss interventions. Between-groups comparisons of different weight loss methods (e.g., lifestyle modification, diet alone, pharmacotherapy) were examined, as were within-group changes for each treatment type. Method MEDLINE was searched for articles published between 1950 and January 2009. Several obesity-related terms were intersected with terms related to depression. Results were filtered to return only studies of human subjects, published in English. Of 5971 articles, 394 were randomized controlled trials. Articles were excluded if they did not report mean changes in weight or symptoms of depression, included children or persons with psychiatric disorders (other than depression), or provided insufficient data for analysis. Thirty-one studies (n = 7937) were included. Two authors independently extracted a description of each study treatment, sample characteristics, assessment methods, and changes in weight and symptoms of depression. Treatments were categorized as: lifestyle modification, non-dieting, dietary counseling, diet-alone, exercise-alone, pharmacotherapy, placebo, or control interventions. Results Random effects models found that lifestyle modification was superior to control and non-dieting interventions for reducing symptoms of depression, and marginally better than dietary counseling and exercise-alone programs. Exercise-alone programs were superior to controls. No differences were found for comparisons of pharmacologic agents and placebos. Within-group analyses found significant reductions in symptoms of depression for nearly all active interventions. A meta-regression found no relationship between changes in weight and changes in symptoms of depression in lifestyle modification interventions. Conclusions On average, obese individuals in weight loss trials experienced reductions in symptoms of depression. Future studies should examine incidence and resolution of clinically significant depressive disorders with weight loss interventions. PMID:21343903

In the UK, thousands of people with high cardiovascular risk are being identified by a national risk-assessment programme (NHS Health Checks). Waste the Waist is an evidence-informed, theory-driven (modified Health Action Process Approach), group-based intervention designed to promote healthy eating and physical activity for people with high cardiovascular risk. This pilot randomised controlled trial aimed to assess the feasibility of delivering the Waste the Waist intervention in UK primary care and of conducting a full-scale randomised controlled trial. We also conducted exploratory analyses of changes in weight. Patients aged 40-74 with a Body Mass Index of 28 or more and high cardiovascular risk were identified from risk-assessment data or from practice database searches. Participants were randomised, using an online computerised randomisation algorithm, to receive usual care and standardised information on cardiovascular risk and lifestyle (Controls) or nine sessions of the Waste the Waist programme (Intervention). Group allocation was concealed until the point of randomisation. Thereafter, the statistician, but not participants or data collectors were blinded to group allocation. Weight, physical activity (accelerometry) and cardiovascular risk markers (blood tests) were measured at 0, 4 and 12 months. 108 participants (22% of those approached) were recruited (55 intervention, 53 controls) from 6 practices and 89% provided data at both 4 and 12 months. Participants had a mean age of 65 and 70% were male. Intervention participants attended 72% of group sessions. Based on last observations carried forward, the intervention group did not lose significantly more weight than controls at 12 months, although the difference was significant when co-interventions and co-morbidities that could affect weight were taken into account (Mean Diff 2.6Kg. 95%CI: -4.8 to -0.3, p = 0.025). No significant differences were found in physical activity. The Waste the Waist intervention is deliverable in UK primary care, has acceptable recruitment and retention rates and produces promising preliminary weight loss results. Subject to refinement of the physical activity component, it is now ready for evaluation in a full-scale trial. Current Controlled Trials ISRCTN10707899 .

Methadone maintenance treatment (MMT) patients are often under-nourished and overweight. The impact of a nutrition intervention program to improve knowledge about healthy food habits and losing weight was studied. Patients were screened for knowledge about nutrition and body mass index (BMI). Those with a low knowledge score or a BMI ≥26 (n=89) were randomly divided into either intervention (two lectures on healthy nutrition followed by weight monitoring over 6weeks), or controls (weighed at baseline, post-lectures and at study closure). The Yale Food Addiction Scale (YFAS), eating behavior rating, and nutrition knowledge questionnaires were used. Knowledge and food habit scores improved in the intervention group (28.4±4.3, 37.2±3.1, 32.5±3.9 pre-, post- and 6-weeks post-lectures, respectively), with no change in the controls (28.6±3.4, 28.2±4.9, 28.1±5.3, repeated measured p(time)=0.001, p(group)=0.001, p(interaction)=0.001); food habit (intervention: 35.0±7.0, 38.4±5.2, 37.5±5.3, controls: 34.0±6.9, 34.7±6.9, 34.6±7.4, p(time)=0.001, p(group)=0.04, p(interaction)=0.06). BMI scores however did not change and were similar in both groups (p=0.9). Of all patients, 10.1% met the criteria of food addiction according to the YFAS, 40.4% lost weight and 28% gained weight, with no group differences. There were more symptoms of food addiction among the patients who gained weight vs. those who lost weight (3.7±2.0 vs. 2.6±1.8, respectively, p=0.04). We concluded that although weight loss was not observed, intervention is recommended for improving knowledge about nutrition and for fostering healthy eating habits with the aim of reducing diet-related morbidity among all MMT patients. Longitudinal program combined with physical activity is needed to study if may lead to weight loss. Copyright © 2017 Elsevier Inc. All rights reserved.

Background: Overweight is epidemic in adolescents and is a major concern because it tracks into adulthood. Evidence supports the efficacy of high-calcium, high-dairy diets in achieving healthy weight in adults. However, no randomized controlled trials of the effect of dairy food on weight and body fat in adolescents have been reported to our knowledge. Objective: The aim was to determine whether increasing calcium intake to recommended amounts with dairy foods in adolescent girls with habitually low calcium intakes would decrease body fat gain compared with girls who continued their low calcium intake. Participants had above-the-median body mass index (BMI; in kg/m 2 ). Design: We enrolled 274 healthy postmenarcheal 13- to 14-y-old overweight girls who had calcium intakes of ≤600 mg/d in a 12-mo randomized controlled trial. Girls were randomly assigned in a 1:1 ratio to 1 of 2 groups within each of 3 BMI percentiles: 50th to <70th, 70th to <85th, and 85th to <98th. The assignments were 1 ) dairy, which included low-fat milk or yogurt servings providing ≥1200 mg Ca/d or 2 ) control, which included the usual diet of ≤600 mg Ca/d. Results: We failed to detect a statistically significant difference between groups in percentage of body fat gain over 12 mo (mean ± SEM: dairy 0.40% ± 0.53% > control; P < 0.45). The effect of the intervention did not differ by BMI percentile stratum. There was no difference in weight change between the 2 groups. Conclusion: Our findings that the dairy group gained body fat similar to the control group provide no support for dairy food as a stratagem to decrease body fat or weight gain in overweight adolescent girls.

To evaluate the effects of exposure to routine magnetic resonance (MR) imaging at 1.5 T during pregnancy on fetal growth and neonatal hearing function in relation to the dose and timing of in utero exposure in a group of newborns at low risk for congenital hearing impairment or deafness. This retrospective case-control study was approved by the local ethics committee, and written informed consent was waived. Between January 2008 and December 2012, a group of 751 neonates exposed to MR imaging in utero and a group of control subjects comprising 10 042 nonexposed neonates, both groups with no risk factors for hearing impairment at birth, were included. Neonatal hearing screening was performed by means of otoacoustic emission testing and auditory brain stem response according to national guidelines, and the prevalence of hearing impairment in the two groups was compared by using a noninferiority test with Wilson score confidence intervals. The effect of MR exposure on birth weight percentile was examined between the singleton neonates in the exposed group and a randomly chosen subset of 1805 singleton newborns of the nonexposed group by performing an analysis of variance. The rate of hearing impairment or deafness was found to be 0% (0 of 751) in the neonates in the exposed group and was not inferior to that in the nonexposed group (34 of 10 042 [0.34%], P < .05). There was no between-group difference in birth weight percentiles (50.6% for exposed vs 48.4% for nonexposed; P = .22). This study showed no adverse effects of exposure to 1.5-T MR imaging in utero on neonatal hearing function or birth weight percentiles. (©) RSNA, 2015.

In this study, we aimed to explain the role of apelin-13 on body weight, food and water intake with serum leptin, ghrelin, neuropeptid Y (NPY) and peptid YY (PYY) levels in male rat. Thirty-two Sprague-Dawley male rats were used for the study. The rats were injected SP (0.9 %) intraperitoneally (i.p) in the control group and 30 (AP30), 100 (AP100) and 300 (AP300) µg/kg apelin-13 in the study groups, respectively, 10 min before the transition to dark period, for 10 days. During the experimental period, with light and dark periods of food and water intake, body weights were recorded in rats. Rats were euthanized and serum samples were obtained. In serum samples leptin, ghrelin, NPY and PYY levels were measured with specific ELISA kit. Apelin-13 was increased body weights in all three (AP30, AP100 and AP300) groups compared with the control group. AP100 and AP300 groups had increased food intake in the dark and the cumulative period, but in the light period food intake values were not significantly increased (p > 0.05). As for the value of water intake, compared with the control group, all dose of apelin-13 increased water intake during the dark and the cumulative period. There was no significant change in water intake in the light period. On the other hand, compared with the control group, serum leptin levels were found to increase in the groups administered 100 and 300 µg/kg of apelin-13 (p < 0.05). Ghrelin levels were found high in all groups treated with apelin-13. Serum levels of NPY decreased only in the 300 µg/kg apelin-13 treated group (p 0.05). Apelin-13 increases body weight in rats as well as food and water intake (dark and cumulative period). Additionally, ghrelin can mediate the orexigenic effect of apelin-13 in the regulation of food intake (Fig. 4, Ref. 37).

The physiological effects of the hydrolysates of white rice protein (WRP), brown rice protein (BRP), and soy protein (SP) hydrolyzed by the food grade enzyme, alcalase2.4 L, were compared to the original protein source. Male Syrian Golden hamsters were fed high-fat diets containing either 20% casein (control) or 20% extracted proteins or their hydrolysates as the protein source for 3 weeks. The brown rice protein hydrolysate (BRPH) diet group reduced weight gain 76% compared with the control. Animals fed the BRPH supplemented diet also had lower final body weight, liver weight, very low density lipoprotein cholesterol (VLDL-C), and liver cholesterol, and higher fecal fat and bile acid excretion than the control. Expression levels of hepatic genes for lipid oxidation, PPARα, ACOX1, and CPT1, were highest for hamsters fed the BRPH supplemented diet. Expression of CYP7A1, the gene regulating bile acid synthesis, was higher in all test groups. Expression of CYP51, a gene coding for an enzyme involved in cholesterol synthesis, was highest in the BRPH diet group. The results suggest that BRPH includes unique peptides that reduce weight gain and hepatic cholesterol synthesis.

Context: Increased prevalence of type 2 diabetes mellitus and prediabetes worldwide is attributed in part to an unhealthy diet. Objective: To evaluate whether 12 weeks of high monounsaturated fatty acid (MUFA) or fiber-rich weight-maintenance diet lowers hepatic fat and improves glucose tolerance in people with prediabetes. Design: Subjects underwent a [6, 6-2H2]–labeled 75-g oral glucose tolerance test to estimate hepatic insulin sensitivity and liver fat fraction (LFF) using magnetic resonance spectroscopy before and after intervention. Setting: Mayo Clinic Clinical Research Trials Unit. Participants: 43 subjects with prediabetes. Intervention: Subjects were randomized into three isocaloric weight-maintaining diets containing MUFA (olive oil), extra fiber, and standard US food (control-habitual diet). Outcome Measures: LFF, glucose tolerance, and indices of insulin action and secretion. Results: Body weight was maintained constant in all groups during the intervention. Glucose and hormonal concentrations were similar in all groups before, and unchanged after, 12 weeks of intervention. LFF was significantly lower after intervention in the MUFA group (P < 0.0003) but remained unchanged in the fiber (P = 0.25) and control groups (P = 0.45). After 12 weeks, LFF was significantly lower in the MUFA than in the control group (P = 0.01), but fiber and control groups did not differ (P = 0.41). Indices of insulin action and secretion were not significantly different between the MUFA and control groups after intervention (P ≥ 0.11), but within-group comparison showed higher hepatic (P = 0.01) and total insulin sensitivity (P < 0.04) with MUFA. Conclusions: Twelve weeks of a MUFA diet decreases hepatic fat and improves both hepatic and total insulin sensitivity. PMID:28323952

Viscous dietary fibers blunt the postprandial rise in blood glucose, however their effect on type 2 diabetes and obesity are not entirely known. This study examined the effect of chronic consumption of the viscous, non-fermentable dietary fiber, hydroxypropyl methylcellulose (HPMC), on glucose control, insulin resistance and liver lipids in an obese diabetic rat model. Three groups of Zucker Diabetic Fatty (ZDF) rats were fed diets containing either 5% non-viscous cellulose (control), low viscosity HPMC (LV-HPMC) or high viscosity HPMC (HV- HPMC) for six weeks. Zucker lean littermates consuming cellulose served as a negative control. Markers of glucose control, including oral glucose tolerance test, glycated hemoglobin and urinary glucose, were measured as well as adiposity and the accumulation of liver lipids. The HPMC diets increased the viscosity of the small intestinal contents and reduced the postprandial rise in blood glucose. The food efficiency ratio was greater with HPMC feeding compared to the obese control and urinary excretion of glucose and ketone bodies was reduced. The two HPMC groups had lower glycated hemoglobin and kidney weights and a reduced area under the curve during a glucose tolerance test, indicating improved glucose control. Epididymal fat pad weight as percent of body weight was reduced in the HV-HPMC group compared to the obese control group. The HV-HPMC group also had lower concentrations of liver lipid and cholesterol and reduced liver weight. However, HV-HPMC feeding did not affect hepatic gene expression of SREBP-1c or FAS. Muscle concentration of acylcarnitines, a lipid intermediate in fatty acid β-oxidation, was not different between the HPMC groups and obese control, suggesting no change in muscle fatty acid oxidation by HPMC. Consumption of the viscous non-fermentable fiber HPMC decreased diabetic wasting, improved glucose control and reduced insulin resistance and fatty liver in a model of obesity with diabetes.

Introduction Obese men have an increased risk of prostate cancer (PCa)-specific mortality. Potential mechanisms include insulin and related proteins. We investigate whether a short-term caloric restriction diet in overweight/obese men with newly diagnosed PCa can lead to measurable changes in patient anthropometrics and insulin-related proteins. Methods Overweight and obese PCa patients choosing active surveillance or radical prostatectomy were randomized to a 6-week, caloric-restricted diet or to continue their current diet. Changes from baseline to end of study in anthropometrics, dietary constituents and serum proteins (insulin, c-peptide, IGF-1, adiponectin, IGF-BP3) were compared between the intervention and control groups using a Generalized Estimating Equation model. Results Nineteen patients were randomized to the intervention (N=10) or control (N=9) group. Men in the intervention group had a 1.7% (3.7 lbs.) mean decline in weight vs. 1.0% (2.0 lbs.) in controls (p<0.05), and a reduced intake of calories, total and saturated fat, protein and starch, (all p<0.1 compared to controls). There was a significant difference (p=0.002) in mean serum IGFBP-3 between the intervention (+2.8%) and control group (−6.9%). Other biomarkers changed with the diet intervention to a degree similar to previous weight loss studies but were not statistically significant compared with controls. Conclusion In this small pilot study, a 6-week caloric restricted diet in men with newly diagnosed PCa produced changes in weight, diet and serum proteins possibly related to prognosis. These results support larger-scale trials testing longer-term weight loss effects on potential PCa progression biomarkers. PMID:23775525

Background and Aim: In today era, broiler industry facing a problem of price hiking of feed of broiler, also in competitive era there should be lower feed cost, lower feed conversion ratio, low feed consumption yet good body weight at marketable age. Materials and Methods: Day-old commercial broiler chicks (n=200) were distributed randomly into 5 dietary treatment groups viz. control (T1), probiotic in the feed @ 100 g/tonne of feed (T2), prebiotic in the feed @ 500 g/tonne of feed (T3), probiotic + prebiotic @ 100 g/tonne and 500 g/tonne of feed, respectively (T4) and probiotic + prebiotic @ 50 g/tonne and 250 g/tonne of feed (T5). The growth of broilers and dressing weight along with the weight of giblet (liver without gall bladder, gizzard without serous layer, and heart without pericardium), Kidney, Abdominal fat, Length of Intestine and dressing percentage were measured. Economics in terms of Return Over Feed Cost (ROFC) and European Performance Efficiency Index (EPEI) was calculated. Results: Among all carcass traits, dressing percentage, abdominal fat weight and abdominal fat percentage (as a percentage of dressed weight) were recorded significant (p<0.05) difference among different treatment groups. The income from selling of the birds was significantly (p<0.05) higher in all treatment groups than the control group but there was a non-significant difference between supplemented groups. Feed cost during whole experimental period was significantly (p<0.05) lower in synbiotic supplemented groups (T4 and T5) than other groups. ROFC of all treatment group found significantly (p<0.05) higher than the control group. Conclusion: It can be concluded that the diet supplemented with synbiotic (100% level) was most efficient in terms of EPEI and synbiotic (50% level) in terms of ROFC. Hence, as feed supplement, synbiotic has a beneficial effect over probiotic and prebiotic when used alone. PMID:27047078

Stephens, Janna D; Yager, Allison M; Allen, Jerilyn

Using smartphone technology and text messaging for health is a growing field. This type of technology is well integrated into the lives of young adults. However, few studies have tested the effect of this type of technology to promote weight loss in young adults OBJECTIVE:: The purpose of this study is to test the effectiveness of a behaviorally based smartphone application for weight loss combined with text messaging from a health coach on weight, body mass index (BMI), and waist circumference in young adults as compared with a control condition. Sixty-two young adults, aged 18 to 25 years, were randomized to receive (1) a smartphone application + health coach intervention and counseling sessions or (2) control condition with a counseling session. All outcome measures were tested at baseline and 3 months. These included weight, BMI, waist circumference, dietary habits, physical activity habits, and self-efficacy for healthy eating and physical activity. The sample was 71% female and 39% white, with an average age of 20 years and average BMI of 28.5 kg/m. Participants in the smartphone + health coach group lost significantly more weight (P = .026) and had a significant reduction in both BMI (P = .024) and waist circumference (P < .01) compared with controls. The results of this weight loss trial support the use of smartphone technology and feedback from a health coach on improving weight in a group of diverse young adults.

Importance Healthcare professionals commonly recommend increased water consumption, typically to 8 cups/d, as part of a weight-reducing diet. However, this recommendation is based on limited evidence and virtually no experimental data in the pediatric age range. Objective The aim of this study was to compare two standard weight-loss diets, either with (Water) or without (Control) additional advice and behavioral support to increase habitual water intake to 8 cups/d. Design 6-month randomized controlled parallel-group design. Setting The trial was conducted at Boston Children’s Hospital, Boston, Massachusetts, between February 2011 and June 2014. Participants 38 overweight and obese adolescents who reported drinking ≤4 cups of water/d. Intervention Both groups received similar weight-reducing interventions, differentiated by water messages but controlled for other dietary recommendations and treatment intensity. The interventions included dietary counseling, daily text messages, and a cookbook with health guides. To support adherence to 8 cups water/d, the Water group received well-defined water messages through counseling and daily text messages, a water bottle, and a water pitcher with filters. The Control group received no specific advice on water consumption. Main Outcome and Measures Primary outcome was 6-month change in body mass index (BMI) z-score. Results All randomized participants completed the study. Both groups reported drinking ~2 cups/d water at baseline. Self-reported change in water intake was greater in the Water Group compared to the Control Group (difference between groups, 1.6; 95% CI, 0.2 to 3.0 cups/d; P=0.03). The 6-month change in BMI z-score did not differ between groups (−0.0; 95% CI, −0.1 to 0.1; P=0.88). Conclusions and Relevance Contrary to hypothesis, advice and behavioral supports to consume 8 cups water/d in the context of a weight-reducing diet did not affect body weight among overweight and obese adolescents. Despite intensive behavior supports, few achieved the 8 cups/d water target. Environmental interventions to reduce barriers to water consumption at school may be necessary in future research of feasibility and effectiveness to achieve the target of an 8-cup/d intake of water in adolescents.

The current study describes detailed eating behaviors, dieting behaviors, and attitudes about shape and weight in 4023 women ages 25 to 45. The survey was delivered on-line and participants were identified using a national quota-sampling procedure. Disordered eating behaviors, extreme weight loss measures, and negative cognitions about shape and weight were widely endorsed by women in this age group and were not limited to White participants. Thirty-one percent of women without a history of anorexia nervosa or binge eating reported having purged to control weight, and 74.5% of women reported that their concerns about shape and weight interfered with their happiness. Unhealthy approaches to weight control and negative attitudes about shape and weight are pervasive even among women without eating disorders. The development of effective approaches to address the impact of these unhealthy behaviors and attitudes on the general well-being and functioning of women is required.

there is a growing concern in the appearance of eating disorders in athletes, especially those that practice sports grouped into weight categories. This affects the way athletes eat, using frequently unhealthy strategies to control weight, especially during the pre-competition period. this study analyses the prevalence of contact sports athletes in developing eating disorders, and how a controlled diet plan can reduce this risk. At the same time, it evaluates the use of the EAT-26 questionnaire to detect such disorders. a randomized frequency study was performed on 244 athletes (158 men, 86 women), who were separated into two groups: those that followed a diet plan given by a nutritionist, and a control group on a free diet. The athletes completed an EAT-26 questionnaire while participating in the University-level National Championships. the free diet group scored significantly higher on the questionnaire. Also, the female athletes controlled diet group scored significantly higher than their male counterparts. the results of the questionnaire indicate that an adequate nutritional program circumvents the use of unhealthy habits to control body weight and therefore avoids developing particular eating disorders. EAT-26 questionnaire does not seem the most appropriate tool to detect these disorders. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

We conducted a study designed to evaluate whether the benefits of intentional weight loss exceed the potential risks in a group of community-dwelling, obese, older adults who were at increased risk for cardiometabolic disease. The CROSSROADS trial used a prospective randomized controlled design to compare the effects of changes in diet composition alone or combined with weight loss with an exercise only control intervention on body composition and adipose tissue deposition (Specific Aim #1: To compare the effects of changes in diet composition alone or combined with weight loss with an exercise only control intervention on body composition, namely visceral adipose tissue (VAT)), cardiometabolic disease risk (Specific Aim #2: To compare the effects of a change in diet composition alone or combined with weight loss with an exercise only control intervention on cardiometabolic disease risk), functional status and quality of life (Specific Aim #3: To compare the effects of a change in diet composition alone or combined with weight loss with an exercise only control intervention on functional status and quality of life). Participants were randomly assigned to one of three groups: Exercise Only (Control) Intervention, Exercise + Diet Quality + Weight Maintenance Intervention, or Exercise + Diet Quality + Weight Loss Intervention. CROSSROADS utilized a lifestyle intervention approach consisting of exercise, dietary, and behavioral components. The development and implementation of the CROSSROADS protocol, including a description of the methodology, detailing specific elements of the lifestyle intervention, assurances of treatment fidelity, and participant retention; outcome measures and adverse event monitoring; as well as unique data management features of the trial results, are presented in this article.

Research suggests that social networks, social support, and social influence are associated with weight trajectories among treatment- and non-treatment-seeking individuals. This study examined the impact of having a social contact who participated in the same group behavioral weight-control intervention in the absence of specific social support training on women engaged in a weight-loss program. Participants (n = 92; 100% female; 54% black; mean age: 46 ± 10 years; mean BMI: 38 ± 6) were grouped based upon whether or not they reported a social contact enrolled previously/concurrently in our behavioral weight-control studies. Primary outcomes were 6-month weight change and treatment adherence (session attendance and self-monitoring). Half of the participants (53%) indicated that they had a social contact; black women were more likely to report a social contact than white women (67.3% versus 39.5%; P < 0.01). Among participants with a social contact, 67% reported at least one contact as instrumental in the decision to enroll in the program. Those with a contact lost more weight (5.9 versus 3.7 kg; P = 0.04), attended more group sessions (74% versus 54%; P < 0.01), and submitted more self-monitoring journals (69% versus 54%; P = 0.01) than those without a contact. Participants' weight change was inversely associated with social contacts' weight change (P = 0.04). There was no association between participant and contact's group attendance or self-monitoring. Social networks may be a promising vehicle for recruiting and engaging women in a behavioral weight-loss program, particularly black women. The role of a natural social contact deserves further investigation.

As morbid obesity increasingly affects Hispanic Americans, the incidence of bariatric procedures among this population is rising. Despite this, prospective research on the effects of comprehensive postoperative education-centered interventions on weight loss and physical activity focused on Hispanic Americans is lacking. To examine whether a comprehensive nutrition education and behavior modification intervention improves weight loss and physical activity in Hispanic Americans with obesity following Roux-en-Y gastric bypass surgery (RYGB). A prospective randomized-controlled trial was conducted between November 2008 and April 2010. At 6 months following RYGB, 144 Hispanic Americans with obesity were randomly assigned to a comprehensive nutrition and lifestyle educational intervention (n=72) or a noncomprehensive approach (comparison group n=72). Those in the comprehensive group received education sessions every other week for 6 weeks in small groups and frequent contact with a registered dietitian. Those in the comparison group received brief, printed healthy lifestyle guidelines. Patients were reassessed at 12 months following surgery. Main outcome measures were excess weight loss and physical activity changes over time. Statistical analyses used t test, ?(2) test, Wilcoxon signed rank, Mann-Whitney U test, and intent-to-treat analysis, significance P<0.05. Participants (mean age 44.5 ± 13.5 years) were mainly Cuban-born women (83.3%). Mean preoperative excess weight and body mass index (calculated as kg/m(2)) were 72.20 ± 27.81 kg and 49.26 ± 9.06, respectively. At 12 months following surgery, both groups lost weight significantly, but comprehensive group participants experienced greater excess weight loss (80% vs 64% from preoperative excess weight; P<0.001) and greater body mass index reduction (6.48 ± 4.37 vs 3.63 ± 3.41; P<0.001) than comparison group participants. Comprehensive group participants were significantly more involved in physical activity (+14 min/wk vs ?4 min/wk; P<0.001) than comparison group participants. Mean protein intake was significantly lower in the comparison group than that in the comprehensive group (P<0.024). Findings support the importance of comprehensive nutrition education for achieving more effective weight reduction in Hispanic Americans following RYGB.

Obesity and overweight have become increasingly a major public health problem across the world. This study aimed at exploring the effects of motivational interviewing on weight efficacy lifestyle among women with obesity and overweight. A single-blind randomized clinical trial study was conducted on 100 overweight and obese women who attended a nutrition clinic. The samples were selected based on the clinical records and assigned into two groups, namely motivational interviewing arm (50 samples) and nutrition education arm (50 samples). Data were collected using a standard validated questionnaire entitled "weight efficacy lifestyle". The intervention was designed according to five motivation sessions and four nutrition education programs, such that the participants of the nutrition education arm were also provided with the nutrition pamphlets related to weight control. Data were finally analyzed using the SPSS statistical software by performing the independent t-test, chi-square, LSD and repeated measures ANOVA tests. P<0.05 were considered statistically significant. The mean age of women was 39.9±9.1 and 36.3±8.9 years in the control and motivational interviewing arms, respectively. Compared with the control group, the score of the motivational interviewing group was statistically significant in terms of weight efficacy lifestyle P=0.0001) and all subscales including social pressure (P=0.0001), physical discomfort (P=0.005), food accessibility (P=0.0001), positive and entertainment activities (P=0.0001), as well as negative emotions (P=0.003). Motivational interviewing appeared to be effective in increasing weight efficacy lifestyle among women with overweight and obesity. IRCT2014051817736N1.

To investigate the potential protective effects of Tualang honey against the toxicity effects induced by Bisphenol A (BPA) on pubertal development of ovaries. This study was conducted on pre-pubertal female Sprague Dawley rats. Animals were divided into four groups (n = 8 in each group). Group I was administered with vehicle 0.2 ml of corn oil (Sigma-Aldrich, USA) using oral gavage daily for six weeks; these animals served as negative control (CO group), Group II was administered with BPA suspended in corn oil at 10 mg/kg body weight and served as positive control (PC group), Group III was administered with 200 mg/kg body weight of Tualang honey 30 min before the administration of BPA at 10 mg/kg (TH group) while Group IV was administered with 200 mg/kg body weight of Tualang honey 30 min before the administration of corn oil (THC group). Body weight of all animals were monitored weekly. The BPA-exposed animals exhibited disruption of their estrus cycle, while those animals treated with BPA together with Tualang honey, exhibited an improvement in percentage of normal estrous cycle. Their ovaries had lower numbers of atretic follicles compared to the PC group but higher than the CO group. Tualang honey has a potential role in reducing BPA-induced ovarian toxicity by reducing the morphological abnormalities of the ovarian follicles and improving the normal estrous cycle.

Gestational diabetes mellitus (GDM) is one of the most common complications of pregnancy and is associated with substantially elevated risk of adverse health outcomes for both mothers and offspring. This quasi-experimental trial was conducted to assess whether a lifestyle intervention in early pregnancy can reduce the incidence of GDM and excessive gestational weight (GWG) gain among Chinese overweight women. Convenience samples of 74 women in gestational weeks 8-12 with a BMI ≥ 24 kg/m(2) were enrolled. They were divided into intervention (N=37) or control group (N=37) according to the time sequence of seeing the doctor. The intervention group was provided with exercise, dietary, weight gain counseling and detailed plans at weeks 8-12 and every month in the second trimester. In addition, each counseling session included a personalized feedback based on their 5-day-records. Follow-up phone calls or emails were conducted every week between antenatal visits. The control group was just provided with exercise, dietary and weight gain counseling at weeks 8-12, besides the usual health education provided at the O&G outpatient department. The lifestyle intervention resulted in a lower incidence of gestational diabetes in the intervention group (9/32, 28.1%) compared with the control group (19/34, 55.9%), p=0.023. Women in the intervention group gained much less weight (6.86 ± 2.31 versus 10.08 ± 3.84 kg, p=0.000) at the end of second trimester. Lifestyle intervention in early pregnancy can reduce the incidence of GDM and prevent excessive maternal weight gain in overweight and obese pregnant women. Copyright © 2015 Elsevier Inc.

Hockey Fans in Training (Hockey FIT) is a gender-sensitized weight loss and healthy lifestyle program. We investigated 1) feasibility of recruiting and retaining overweight and obese men into a pilot pragmatic randomized controlled trial and 2) potential for Hockey FIT to lead to weight loss and improvements in other outcomes at 12 wk and 12 months. Male fans of two ice hockey teams (35-65 yr; body mass index ≥28 kg·m) located in Ontario (Canada) were randomized to intervention (Hockey FIT) or comparator (wait-list control). Hockey FIT includes a 12-wk active phase (weekly, coach-led group meetings including provision of dietary information, practice of behavior change techniques, and safe exercise sessions plus incremental pedometer walking) and a 40-wk minimally supported phase (smartphone app for sustaining physical activity, private online social network, standardized e-mails, booster session/reunion). Measurement at baseline and 12 wk (both groups) and 12 months (intervention group only) included clinical outcomes (e.g., weight) and self-reported physical activity, diet, and self-rated health. Eighty men were recruited in 4 wk; trial retention was >80% at 12 wk and >75% at 12 months. At 12 wk, the intervention group lost 3.6 kg (95% confidence interval, -5.26 to -1.90 kg) more than the comparator group (P < 0.001) and maintained this weight loss to 12 months. The intervention group also demonstrated greater improvements in other clinical measures, physical activity, diet, and self-rated health at 12 wk; most sustained to 12 months. Results suggest feasible recruitment/retention of overweight and obese men in the Hockey FIT program. Results provide evidence for the potential effectiveness of Hockey FIT for weight loss and improved health in at-risk men and, thus, evidence to proceed with a definitive trial.

Abstract Background: Weight reduction without behavioral modification is not sustainable. However, with a technology application such as teledietetics, the recording process could be a cognitive cue for individuals to change their eating behavior. This study tested obese participants to determine whether teledietetics shows better results in weight reduction. Study Design and Methods: We conducted a double-blinded randomized controlled trial. The participants in the food diary (FD) and electronic diary (ED) groups recorded their dietary intakes in logbooks and on an electronic diary system, respectively. The participants in the control group (CG) did nothing. Subjects were adults 20–60 years of age with a body mass index (BMI) of ≥25 kg/m2. The ED and FD groups were the intervention groups and were compared with the CG group. The participants' body weights, BMIs, fat percentages, waist-to-hip ratios (WHRs), and mean arterial pressures (MAPs) were measured before the study, at Week 6, and at Week 12. Demographic data were collected using self-administered questionnaires. A chi-squared test and descriptive statistics were used to describe the demographic and biomeasurement data. Repeated-measures analysis of variance was used to evaluate the effectiveness of the three groups over time. Results: Significant decreases in body weight (F1.705,86.950=20.508, p<0.001) and BMI (F1.657, 84.486=21.256, p<0.001) and insignificant decreases in fat percentage (F2,94=0.547, p=0.581), WHR (F1.785,91.052=2.888, p=0.067), and MAP (F2,94=7.542, p=0.0001) were observed among the three measurement times. Conclusions: Electronic dietary records were better than food diaries in terms of fat percentage reduction in our trials, indicating that teledietetics increases healthy-eating awareness.

Urban bus operators are an occupational group with high rates of overweight and obesity. Understanding methods bus operators use for weight control may be important; there may be increased risk for these workers to engage in less healthy weight management behaviours due to stressful working conditions. To examine the prevalence of unhealthy and healthy weight control behaviours used by bus operators and examine associations between use of unhealthy weight control behaviours and work-related and sociodemographic variables. Bus operators from four different transit garages were invited to complete a self-administered survey; height and weight were measured by research staff. Unhealthy and healthy weight control behaviours, work hours, work schedule and social support were measured with self-report items on the employee survey. Logistic regression analysis was conducted to estimate associations. Nearly 60% of bus operators endorsed at least one unhealthy method; over 50% reported skipping meals, 30% fasted and 10% reported taking diet pills in the past year. Bus operator gender, race, body mass index status and hours worked per week showed significant associations with using at least one unhealthy weight control behaviour. Worksite interventions should emphasize the benefit of healthy eating and physical activity but should also address the use of less healthy methods for weight control for individuals employed in transportation occupations.

Prevalence of multiple health risk behaviors is growing, and obesity and smoking are costly. Weight gain associated with quitting smoking is common and can interfere with quit success. Efficacy of adding weight management to tobacco cessation treatment has been tested with women in group sessions over an extended period of time, but has never been tested in real-world settings with men and women seeking help to quit. This paper describes the Best Quit study which tests the effectiveness of delivering tobacco and weight control interventions via existing quitline infrastructures. Eligible and consenting smokers (n = 2550) who call a telephone quitline will be randomized to one of three groups; the standard quitline or standard quitline plus a weight management program added either simultaneously or sequentially to the tobacco program. The study aims to test: 1) the effectiveness of the combined intervention on smoking cessation and weight, 2) the cost-effectiveness of the combined intervention on cessation and weight and 3) theoretically pre-specified mediators of treatment effects on cessation: reduced weight concerns, increased outcome expectancies about quitting and improved self-efficacy about quitting without weight gain. Baseline, 6 month and 12 month data will be analyzed using multivariate statistical analyses and groups will be compared on treatment adherence, quit rates and change in weight among abstinent participants. To determine if the association between group assignment and primary outcomes (30-day abstinence and change in weight at 6 months) is moderated by pre-determined baseline and process measures, interaction terms will be included in the regression models and their significance assessed. This study will generate information to inform whether adding weight management to a tobacco cessation intervention delivered by phone, mail and web for smokers seeking help to quit will help or harm quit rates and whether a simultaneous or sequential approach is better at increasing abstinence and reducing weight gain post quit. If proven effective, the combined intervention could be disseminated across the U.S. through quitlines and could encourage additional smokers who have not sought cessation treatment for fear of gaining weight to make quit attempts.

This experiment was conducted to investigate the effect of the inclusion of saltbush (Atriplex sp.) on the productive performance and blood mineral profile of fattening lambs. Eighteen Awassi lambs, 70 +/- 3 days of age and 23 +/- 1.8 kg body weights, were randomly selected and divided into three equal groups. Lambs in group one (control) were offered 0.2 kg/day shredded straw of barley (tibin) as the sole source of roughage, while lambs in treatment groups 2 and 3 were provided either 0.2 kg/day Atriplex nummularia or Atriplex halimus as their sole roughage content for 10 weeks. All lambs were also provided 1.1 kg/day of concentrate ration. Although lambs fed A. halimus had significantly (P < 0.05) lower dry matter intake than the control group, the daily weight gain of the two groups of lambs were not significantly different (P > 0.05). Lambs fed either A. nummularia or A. halimus had significantly lower (P < 0.05) calcium and copper levels but significantly higher (P < 0.05) cobalt levels in their blood serum than the control group. Zinc blood serum level was not affected (P > 0.05) by the treatment diets. These results suggested that A. nummularia and A. halimus can substitute for barley straw in the ration of fattening Awassi lambs without compromising lambs weight gain; however, special attention should be given to the mineral status in lambs if saltbush is a major feed component for prolonged periods of time.

Premature infants especially those with birth weight < 1500 g suffer from Anaemia of prematurity (AOP) and associated problems. Erythropoietin therapy is a safe effective way to prevent and to treat anaemia of prematurity. To evaluate the effect of short-term administration of recombinant human erythropoietin (rHuEPO) with iron and folic acid in very low birth weight (VLBW) neonates in the prevention of anaemia of prematurity. A randomized controlled trial was carried out at Dhaka Shishu Hospital. Sixty preterm very low birth weight (PTVLBW) babies were enrolled in this study. Thirty were assigned to rHuEPO group and 30 as control. Baseline haematologic values were estimated before administration of rHuEPO. From day 7 of life rHuEPO-200 IU/kg/dose subcutaneously every alternate day for 2 weeks was administered to rHuEPO group. All infants in both groups have received oral iron, folic acid from day 14. Clinical and haematological assessment was done at 6 and 10 weeks of life. Baseline clinical characteristics and haematologic values were almost similar in both groups. This study has shown increase in haematological values (haemoglobin and haematocrit) and reduction in the number of blood transfusions during both the 1st and 2nd follow up in rHuEPO group in comparison to control group (p < 0.01). Short-term rHuEPO appears to be very effective in prevention of Anaemia of prematurity.

Background: The readiness of mothers to take care for infants at discharge is a critical issue. Poor readiness of mothers in taking care of premature infants at the time of discharge is associated with potential adverse consequences. This study examined the effect of implementing mothers’ empowerment program on the weight gain and duration of hospitalization in premature infants. Materials and Methods: This study was a quasi-experimental before-after study with a control group, in which 80 mothers with premature infants who were hospitalized in NICU Level II of two hospitals were recruited in the study. Mothers’ empowerment program was implemented as a three-stage training program for the intervention group. Mothers’ readiness questionnaire was completed by the mothers before the intervention and at the discharge time. The changes in mean of mothers’ readiness scores were compared in both the groups. Results: The mean of daily weight gain in infants of the intervention group (3.95 g) was significantly higher than that of the infants in the control group (−0.9 g) (P = 0.003). The average duration of hospitalization for infants in the intervention and control groups was 15.45 days and 20.95 days, respectively, showing a statistically significant difference (P = 0.003). Conclusions: Providing training to the mothers regarding how to care for premature infants can be a useful and effective method in the process of weight gain of premature and low-birth newborns, and may shorten the duration of infants’ hospitalization.

Hypothalamic amenorrhea and energy restriction during puberty affect peak bone mass accrual. One hypothesis suggests energy restriction alters hypothalamic function resulting in suppressed estradiol levels leading to bone loss. However, both positive and negative results have been reported regarding energy restriction and bone strength. Therefore, the purpose of this study was to investigate energy restriction and hypothalamic suppression during pubertal onset on bone mechanical strength and the osteogenic capacity of bone marrow-derived cells in two models: female rats treated with gonadotropin releasing hormone antagonists (GnRH-a) or 30% energy restriction. At 23 days of age, female Sprague Dawley rats were assigned to three groups: control group (C, n=10), GnRH-a group (n=10), and Energy Restriction (ER, n=12) group. GnRH-a animals received daily injections for 27 days. The animals in the ER group received 70% of the control animals’ intake. After sacrifice (50 days of age), body weight, uterine and muscle weights were measured. Bone marrow-derived stromal cells were cultured and assayed for proliferation and differentiation into osteoblasts. Outcome measures included bone strength, bone histomorphometry and architecture, serum IGF-1 and osteocalcin. GnRH-a suppressed uterine weight, decreased osteoblast proliferation, bone strength, trabecular bone volume and architecture compared to control. Elevated serum IGF-1 and osteocalcin levels and body weight were found. The ER model had an increase in osteoblast proliferation compared to the GnRH-a group, similar bone strength relative to body weight and increased trabecular bone volume in the lumbar spine compared to control. The ER animals were smaller but had developed bone strength sufficient for their size. In contrast, suppressed estradiol via hypothalamic suppression resulted in bone strength deficits and trabecular bone volume loss. In summary, our results support the hypothesis that during periods of nutritional stress the increased vertebral bone volume may be an adaptive mechanism to store mineral which differs from suppressed estradiol resulting from hypothalamic suppression.

Background Intervention strategies that harness the body's appetite and satiety regulating signals provide a means of countering excessive energy intake. Methods Eighty-two subjects were enrolled (18–60 years, body mass index: 25–40 kg/m2) in a randomized, placebo-controlled, double-blind, parallel trial. During a 12-week period, the effects of Olibra™ fat emulsion (2.1 g twice daily) on food intake, appetite, satiety, weight, and body composition were compared with those of a twice daily administered placebo (1.95 g milk fat). On days -7, 0, and 28, Olibra or the placebo added to 200 g of yogurt was served at breakfast and lunch. Food intake, appetite, and satiety were assessed after lunch and dinner. Body weight was measured on days -7, 0, 14, 28, 56, and 84. Body fat, waist circumference, and waist-hip ratio were determined on days 0 and 84. The Eating Inventory was administered at screening and on day 28. Data relating to 71 subjects were analyzed using analysis of covariance. Results At 12 weeks, body weight was reduced in the test group (2.17 ± 0.46 kg standard error of the mean, p < .0001) and the control group (1.68 ± 0.42 kg, p < .0001). Waist circumference decreased by 2.93 ± 0.85 cm in the test group (p = .001) and by 1.78 ± 0.74 cm in the control group (p = .02). Differential weight and waist circumference reductions were not significant. Hunger scores (Eating Inventory) decreased more in the test group (p = .0082). Differential group effects were not significant for body fat, waist-hip ratio, food intake, appetite, and satiety. Conclusions At this dose, Olibra did not exert a consistent effect on food intake, appetite regulation, body weight, or body composition. PMID:22768902

High viscosity fibre is known to exert many beneficial effects on appetite and metabolism. It could potentially help in weight management, in dieting or nondieting individuals. The present study investigated the effects of the daily intake of a novel high viscosity polysaccharide (HVP) over 3 months in nondieting obese or overweight men and women. The study comprised a double-blind, randomised controlled clinical trial. Participants ingested 5-15 g per day of either HVP (n = 29, experimental group) or inulin (n = 30, control group) for 15 weeks. Changes in anthropometry (weight, waist and hip circumferences), blood lipids and glucose tolerance were studied from the beginning to the end of administration. Compliance and tolerance were examined. Differences appeared between HVP and inulin supplementation in female participants only. Mean (SD) decreases in body weight [1.6 (3.2) kg; approximately 2% of initial weight] and hip circumference [2.8 (3.6 ) cm] occurred in women of the HVP group but not in controls (Time × Group interactions, P ≤ 0.002). Total, high-density lipoprotein and low-density lipoprotein-cholesterol were lower at the end of supplementation in the women of the HVP group compared to controls (P ≤ 0.021). No effect appeared in waist circumference and triacylglycerol. No difference was noted in the number or severity of the adverse effects reported in both groups. Adverse effects were mild and agreed with commonly reported reactions to intake of dietary fibre. Beneficial although modest effects appeared after several weeks of daily HVP intake in nondieting obese or overweight women. The effects of HVP should be investigated in the context of a weight loss programme. © 2011 The Authors. Journal of Human Nutrition and Dietetics © 2011 The British Dietetic Association Ltd.

SisterTalk: final results of a culturally tailored cable television delivered weight control program for Black women

PubMed Central

2013-01-01

Background Obesity among Black women continues to exceed that of other women. Most weight loss programs created without reference to specific cultural contexts are less effective for Black than White women. Weight control approaches accessible to Black women and adapted to relevant cultural contexts are important for addressing this problem. This paper reports the final results of SisterTalk, the randomized controlled trial of a cable TV weight control program oriented toward Black women. Methods A five group design included a comparison group and a 2 × 2 factorial comparison of a) interactive vs. passive programming and b) telephone social support vs no telephone support, with 12 weekly initial cable TV programs followed by 4 monthly booster videos. At baseline, 3, 8, and 12 months post randomization, telephone and in person surveys were administered on diet, physical activity, and physical measurements of height and weight were taken to calculate body mass index (BMI). Analysis of variance (ANOVA) was used to examine differences over time, and between treatment and comparison groups. Dose variables reflecting use of the TV/video and written materials were also assessed. Results At 3 months, BMI, weight, and dietary fat were significantly lower and physical activity significantly higher among women exposed to the Cable TV intervention compared to the wait-list comparison group. Significant dietary fat differences were still observed at 8 and 12 month evaluations, but not BMI or physical activity differences. Main effects were not observed for interactive programming or enhanced social support at any time point. Within the intervention group, higher watching of the TV series and higher reading of educational materials were both (separately) associated with significantly lower dietary fat. Conclusions Cable TV was an effective delivery channel to assist Black women with weight control, increasing physical activity and decreasing dietary fat during an initial intervention period, but only dietary changes persisted Enhanced social support and the ability to interact with others during the show were not effective complementary intervention components as conducted in this trial. Future research to strengthen the ability of this approach to achieve long term effects may offer even more promising outcomes. PMID:24373253

To examine women's weight control practices and their effectiveness in preventing weight gain. Retrospective cohort study of weight control practices and 2-year weight change among mid-age women participating in the Australian Longitudinal Study on Women's Health (ALSWH). 11,589 Australian women (aged 47-52 years). The prevalence and types of self-reported weight control practices used were assessed by a nine-item instrument. Two-year weight change was self-reported and adjusted for baseline body mass index (BMI) and other potential confounders. Seventy-four per cent of the cohort (N=8556) reported actively trying to control their weight. Dietary modification was used more frequently than exercise. Two-thirds of the weight-controlling women used a combination of practices, the two most common being 'decreased food quantity, cut down on fats/sugars and exercise' (32%, baseline BMI 25.87(0.10)), and 'decreased food quantity and cut down on fats/sugars without exercise' (15.6%, baseline BMI 27.04(0.14)). Potentially health-damaging practices (smoking, laxatives, fasting) were relatively uncommon, at 7.9%. Only one combination of practices (decreased food quantity, cut down on fats/sugars, use of a commercial weight loss programme and exercise) prevented mean weight gain (-0.03 kg), whereas the mean (s.d.) weight of the cohort increased (+1.19(4.78)) over the 2-year period. The majority of mid-age women attempting weight control used practices consistent with public health messages. Despite their efforts, the group was mostly unsuccessful in preventing weight gain. Public health authorities and health practitioners may need to make more quantitative recommendations and emphasize the importance of balancing physical activity with dietary intake to achieve successful weight control for women at this life stage.

Short-term weight loss is accompanied by bone loss in postmenopausal women. The longer-term impact of weight loss on bone in reduced overweight/obese women compared with women who regained their weight was examined in this study using a case-control design. Postmenopausal women (N = 42; mean [SD] body mass index, 28.3 [2.8] kg/m; mean [SD] age, 60.7 [5.5] y) were recruited 2 years after the start of a 6-month weight loss trial; those who maintained their weight (weight loss maintainer [WL-M] group) were matched to a cohort of women who regained their weight (weight loss regainer [WL-R] group). Serum hormones and bone markers were measured in a subset. Bone mineral density (BMD) at the femoral neck, trochanter, spine, radius, and total body, and soft-tissue composition were taken at baseline, 0.5 years, and 2 years. During weight loss, both groups lost 9.3% (3.4%) of body weight, with no significant difference between the groups. After weight loss, weight change was -0.1% (2.7%) and 6.0% (3.3%) in the WL-M (n = 22) and WL-R (n = 20) groups, respectively. After 2 years, both groups lost BMD at the femoral neck and trochanter (P ≤ 0.01), whereas only the WL-M group reduced BMD at the 1/3 radius (P < 0.001). There was greater BMD loss at the trochanter (-6.8% [5.7%]) and 1/3 radius (-4.5% [3.3%]) in the WL-M group compared with the WL-R group after 2 years. Multiple linear regression showed that change in leg fat mass (but not trunk fat) contributed to trochanter BMD loss (P < 0.05). After 2 years, there is no BMD recovery of weight reduction-induced bone loss, irrespective of weight regain. These data suggest that the period after weight loss may be an important point in time to prevent bone loss for those who maintain weight and those who regain weight.

The aim of this study was to investigate the effect of a 12-month moderate-to-vigorous exercise program combining aerobic and muscle strength training on body composition among sedentary, postmenopausal women. A randomized controlled trial was conducted. A total of 189 sedentary postmenopausal women (age 50-69 y, body mass index 22-40 kg/m2) were randomly assigned to an exercise (n = 96) or a control group (n = 93). Study parameters measured at baseline, 4 months, and 12 months were as follows: body weight and body height (body mass index), waist and hip circumference (body fat distribution), and dual-energy x-ray absorptiometry (total body fat and lean mass). Differences in changes in study parameters between exercise and control group were examined with generalized estimating equations analysis. The exercise program did not result in significant effects on weight, body mass index, and hip circumference. The exercise group experienced a statistically significant greater loss in total body fat, both absolute (-0.33 kg) (borderline) as in a percentage (-0.43%) compared with the control group. In addition, lean mass increased significantly (+0.31 kg), whereas waist circumference (-0.57 cm) decreased significantly compared with the control group. We conclude that a 12-month exercise program combining aerobic and muscle strength training did not affect weight but positively influenced body composition of postmenopausal women. Affecting body fat distribution and waist circumference may have important health implications because it is an independent risk factor in obese but also in nonobese people. Therefore, this study gives further credence to efforts of public health and general practitioners aiming to increase physical activity levels of postmenopausal women.

Timed-pregnant Sprague-Dawley rats were exposed whole body to N,N-diethylethanolamine vapor for 6 h per day on gestational days (GD) 6-15 at targeted concentrations of 33, 66 or 100 ppm. Dams were sacrificed on GD 21. There was no maternal mortality in any exposed groups. Maternal toxicity observed in the 100 ppm group included dry rales, reduced body weight (9.5%) on GD 15 and reduced weight gain (48%) during exposure. Suppression of body weight gain was also noted in the 66 ppm group during GD 12-15. There were no effects of treatment on gestational parameters, including pre- and post-implantation loss or sex ratio. Mean fetal body weights in treated groups were comparable to controls. There was no increase in the incidence of total malformations (external, visceral or skeletal) or individually by category. The incidence of a single developmental variation (hypoplastic bones of the forepaw) in the 100 ppm groups was statistically significantly decreased relative to that of controls. The no-observed-adverse-effect level was 33 ppm for maternal toxicity but greater than 100 ppm for embryofetal toxicity and teratogenicity.

Constipation is one of the most common gastrointestinal complaints worldwide. This study examined the effects of fig (Ficus carica L.) paste for the treatment of loperamide-induced constipation in a rat model. Animals were divided into one normal control group and four experimental groups (0, 1, 6, and 30 g/kg). Loperamide (2 mg/kg, twice per day) was injected intraperitoneally to induce constipation in the four experimental groups. Fig paste was administered for 4 weeks to assess its anti-constipation effects. Fecal pellet number, weight and water content were increased in the fig-treated groups as compared to the control group. Reductions in body weight and increased intestinal transit length were observed in the fig-treated groups. Fecal pellet number was reduced in the distal colons of the fig-treated rats. Exercise and ileum tension increased in the experimental groups as compared to the control group. According to histological analyses, the thickness of the distal colon and areas of crypt epithelial cells that produce mucin were increased in the fig-treated groups in a dose-dependent manner. Constipation was decreased when fig fruit was fed to rats. Specifically, fecal number, weight, and water content, as well as histological parameters such as thickness and mucin areas in the distal colon were improved. Fig treatment may be a useful therapeutic and preventive strategy for chronic constipation. Copyright © 2011 Elsevier Ltd. All rights reserved.

The purpose of this study was to compare the effect of naringin 100mg/kg in combination with pravastatin 10mg/kg by gavage for 6weeks compared with monotherapy over lipid profiles, glucose levels and weight in murine model of obesity. The study design was planned with 5 groups of 6 male Wistar Albina rats: Group 1: control with balanced food and vehicle (C-); Group 2: control with Obesity and vehicle (C+); Group 3: Obesity+naringin (N); Group 4: Obesity+pravastatin (P); Group 5: Obesity+pravastatin+naringin (NP). Obesity was developed with a food model. The naringin groups showed a decrease in weight gain and low glucose values compared to the control group (weight NP:311.4 vs C+:348.6; glucose NP: 173.12 vs C+:235.56) (p<0.05); the group with naringin+pravastatin combination showed the total cholesterol (TC), LDL and triglycerides (TGs) to normal levels (TC NP:51.6 vs C+:83.4; LDL NP:9.32 vs C+:32.32; TGs NP:39.4 vs C+:89.4) (p<0.05); but was not statistically significant compared with monotherapy. The combination of naringin and pravastatin did not appear to be better than monotherapy on lipids, but its use could generate euglycemic and antiobesogenic effects, in addition to diminishing the adverse hepatic effects of pravastatin in rats.

The aim of the study was to assess the effect of the association of entomopathogenic nematodes and fungi on Rhipicephalus microplus. The nematodes used were Heterorhabditis bacteriophora HP88 and Heterorhabditis indica LPP1 and the fungi were Metarhizium anisopliae IBCB 116 and Beauveria bassiana ESALQ 986. In the groups treated with the fungi, the females were immersed for 3 min in a conidial suspension, while in the groups treated with the nematodes, the ticks were exposed to infective juveniles. To evaluate the interaction between entomopathogens, the females were first immersed in a conidial suspension and then exposed to the nematodes. The egg mass weight and hatching percentage values of the groups treated with M. anisopliae IBCB 116 and B. bassiana ESALQ 986 in the two experiments were statistically similar (p > 0.05) to the values of the control group. In the groups treated only with nematodes, there was a significant reduction (p < 0.05) in the egg mass weight, a fact also observed for the hatching percentage of the group treated with H. indica LPP1. In all the groups treated with nematodes in association with fungi, there was a significant reduction (p < 0.05) in the egg mass weight and hatching percentage. The percentage of control of the groups treated with fungi alone varied from 31 to 55%. In the groups treated with nematodes associated or not with fungi, the control percentage was always greater than 90% and reached 100% in the group treated with H. bacteriophora HP88 associated with the fungus M. anisopliae IBCB 116.

Insulin binding and glucose uptake of adipocytes in rats adapted to hypergravitational force

Kobayashi, M.; Mondon, C. E.; Oyama, J.

1980-01-01

Rats were exposed to 4.15 g for 1 yr and weight and age matched, and lean noncentrifuged rats were used as control groups. Rats exposed to chronic hypergravity (hypergravic rats) were found to show lower ambient insulin levels, greater food intake with smaller body weight gain, and decreased size of isolated adipocytes. The ability of adipocytes from the hypergravic rats to bind insulin was increased. With Scatchard analysis, both number and affinity of receptors were increased. In contrast to the increased binding, glucose transport was found to be decreased in adipocytes from these animals. However, when the data were expressed as a percentage of maximal effect, the half maximal insulin effect for both the hypergravic and lean control groups was produced at an insulin concentration of 0.23 + or - 0.02 ng/ml, which was lower than the insulin concentration of 0.31 + or - 0.02 ng/ml for the weight-matched control group (P less than 0.05). This increased insulin sensitivity in the hypergravic group was accounted for by an increased number of receptors.

Excessive generation of free radicals plays a critical role in the pathogenesis of radiation-induced brain injury. This study was designed to evaluate the protective effect of edaravone, a free radical scavenger, on radiation-induced brain necrosis in patients with nasopharyngeal carcinoma. Eligible patients were randomized 1:1 to the control group and the edaravone group (intravenous 30 mg twice per day for 2 weeks). Both groups received intravenous conventional steroid therapy and were monitored by brain MRI and LENT/SOMA scales prior to the entry of the trial and at 3-months after completing the trial. The primary end point was a 3-month response rate of the proportional changes determined by MRI. The trial is registered at Clinicaltrials.gov Identifier: NCT01865201. Between 2009 and 2012, we enrolled 154 patients. Of whom 137 were eligible for analysis. The volumes of necrosis estimated on T(2)-weighted image showed that 55.6 % edaravone-treated patients (40 out of 72) showed edema decreases ≥25 %, which was significantly higher than that in the control group (35.4 %, 23 out of 65, p = 0.025). Forty-four patients treated with edaravone (61.1 %) reported improvement in neurologic symptoms and signs evaluated by LENT/SOMA scales, while the rate was 38.5 % in the control group (p = 0.006). MRI of the edaravone group showed a significant decrease in area of T(1)-weighted contrast enhancement (1.67 ± 4.69 cm(2), p = 0.004) and the T(2)-weighted edema (5.08 ± 10.32 cm(2), p = 0.000). Moreover, compared with those in control group, patients with edaravone exhibited significantly better radiological improvement measured by T(2)-weighted image (p = 0.042). Administration of edaravone, in adjunct to steroid regimen, might provide a better outcome in patients with radiation-induced brain necrosis.

Background: Home visit program can be effective in infants’ growth and development. The present study aimed to investigate the effect of home visit program on preterm infants’ growth and development within 6 months. Methods: It was a double-blind clinical trial study. The study was conducted in Hafez, Hazrat-e-Zeinab, and Namazee Hospitals affiliated to Shiraz University of Medical Sciences, Shiraz, Iran from 2010 to 2011. Preterm infants were divided into intervention (n=30) and control groups (n=30) through blocked randomization. The intervention group received home visit training program for 6 months, while the control group only received the hospital’s routine care. Then, the infants’ growth indexes, including weight, height, and head circumference, and development criteria were compared on the first day of admission in Neonatal Intensive Care Unit, and then first, second, third, and sixth months. The data were analyzed using Chi-square, independent t-test, and repeated measures ANCOVA. Results: The mean weight of the intervention and control group infants was 7207.3±1129.74 and 6366.7±922.26 gr in the sixth month. Besides, the intervention group infants’ mean weight was higher compared to the control group after six months (t=-3.05, P=0.03). Also, a significant difference was found between the two groups regarding development indexes, such as following moving objects with the head, keeping the head stable when changing the position from lying to sitting,  producing “Agha” sound, and taking objects by hand (P<0.05) during six months of age. Conclusion: The results showed that the home visit program was effective in preterm infants’ weight gain and some development indexes at the sixth month. Considering the importance of infants’ growth and development, healthcare staff is recommended to incorporate home visit training into their programs, so that steps can be taken towards improvement of preterm infants’ health.

Obesity is a significant public health problem that is affecting people and their pets. The human-companion animal bond and the role of pets in providing social support provides a rationale framework for studying the effectiveness of a combined people and pets (PP) exercising together (PPET) weight loss program. Thirty-six pairs of overweight or obese people with an obese pet (PP) and 56 overweight or obese people only (PO) participated in a 1-year prospective controlled weight loss study. In a group format, people received dietary and physical activity counseling, and dogs were fed a calorie-controlled prescription diet. Physical activity was recorded using the physical activity recall questionnaire. Completion rates at 1 year were 61% for the PP group and 58% for the PO group. Mean weight losses at 12 months using last observation carried forward were 4.7% (PP) and 5.2% (PO). Mean weight loss among the dogs was 15%. Time spent in physical activity increased in both groups to 3.9 (PP) and 3.5 (PO) h/wk. Two-thirds of total physical activity in the PP group was spent with the dogs. The PPET study is the first program to demonstrate the effectiveness of a combined PP weight loss program. This fresh approach to the dual obesity epidemic builds on the human-companion animal bond. Consideration of social support for weight loss of family members, friends, and coworkers should be extended to include pets.

To characterise the anthropometric and body composition profile of a sample of fibromyalgia women and men from southern Spain and compare them with non-fibromyalgia controls. The cross-sectional study comprised 566 (51.9 ± 8.3 years) fibromyalgia women vs. 249 (49.3 ± 9.9 years) control women; and 24 (47.0 ± 8.4 years) fibromyalgia men vs. 56 (49.7 ± 11.5 years) control men. Body composition and cardiorespiratory fitness were assessed by means of a bioelectric impedanciometer and the 6-minute walk test, respectively. All body composition para-meters (except muscle mass) differed between fibromyalgia and control women (all, p<0.01) even after controlling for several key variables (all, p<0.05). The effect sizes observed were small-medium. When cardiorespiratory fitness was included as covariate, body composition was no longer different between the women study groups. No differences in body composition were observed between fibromyalgia and control men (all, p>0.05). Weight status differed between women groups, with 11% lower normal-weight and 17% higher obesity prevalence for the fibromyalgia women group (p<0.001), but not between men groups (p=0.711). Seventy-two percent of the fibromyalgia women and 79% of the fibromyalgia men were overweight-obese. Sixty-one percent of the control women and 83% of the control men were overweight-obese. Obesity is a greater common condition among fibromyalgia women compared to their counterparts from southern Spain, which might be explained by lower levels of cardiorespiratory fitness in fibromyalgia. However, fibromyalgia and control men do not differ on either body composition or weight status, in spite of the lower cardiorespiratory fitness found in the fibromyalgia men group.

An aim of weight loss is to reduce the risk of type 2 diabetes (T2D) in obese subjects. However, the relation with long-term glycemic improvement remains unknown. We evaluated the changes in lipid composition during weight loss and their association with long-term glycemic improvement. We investigated the plasma lipidome of 383 obese, nondiabetic patients within a randomized, controlled dietary intervention in 8 European countries at baseline, after an 8-wk low-caloric diet (LCD) (800-1000 kcal/d), and after 6 mo of weight maintenance. After weight loss, a lipid signature identified 2 groups of patients who were comparable at baseline but who differed in their capacities to lose weight and improve glycemic control. Six months after the LCD, one group had significant glycemic improvement [homeostasis model assessment of insulin resistance (HOMA-IR) mean change: -0.92; 95% CI: -1.17, -0.67)]. The other group showed no improvement in glycemic control (HOMA-IR mean change: -0.26; 95% CI: -0.64, 0.13). These differences were sustained for ≥1 y after the LCD. The same conclusions were obtained with other endpoints (Matsuda index and fasting insulin and glucose concentrations). Significant differences between the 2 groups were shown in leptin gene expression in adipose tissue biopsies. Significant differences were also observed in weight-related endpoints (body mass index, weight, and fat mass). The lipid signature allowed prediction of which subjects would be considered to be insulin resistant after 6 mo of weight maintenance [validation's receiver operating characteristic (ROC) area under the curve (AUC): 71%; 95% CI: 62%, 81%]. This model outperformed a clinical data-only model (validation's ROC AUC: 61%; 95% CI: 50%, 71%; P = 0.01). In this study, we report a lipid signature of LCD success (for weight and glycemic outcome) in obese, nondiabetic patients. Lipid changes during an 8-wk LCD allowed us to predict insulin-resistant patients after 6 mo of weight maintenance. The determination of the lipid composition during an LCD enables the identification of nonresponders and may help clinicians manage metabolic outcomes with further intervention, thereby improving the long-term outcome and preventing T2D.

Clinical trials evaluating the use of erythropoietin (Epo) have demonstrated a limited reduction in transfusions; however, long-term developmental follow-up data are scarce. We compared anthropometric measurements, postdischarge events, need for transfusions, and developmental outcomes at 18 to 22 months' corrected age in extremely low birth weight (ELBW) infants treated with early Epo and supplemental iron therapy with that of placebo/control infants treated with supplemental iron alone. The National Institute of Child Health and Human Development Neonatal Research Network completed a randomized, controlled trial of early Epo and iron therapy in preterm infants < or =1250 g. A total of 172 ELBW (< or =1000-g birth weight) infants were enrolled (87 Epo and 85 placebo/control). Of the 72 Epo-treated and 70 placebo/control ELBW infants surviving to discharge, follow-up data (growth, development, rehospitalization, transfusions) at 18 to 22 months' corrected age were collected on 51 of 72 Epo-treated infants (71%) and 51 of 70 placebo/controls (73%) by certified examiners masked to the treatment group. Statistical significance was determined using chi2 analysis. There were no significant differences between treatment groups in weight or length or in the percentage of infants weighing <10th percentile either at the time of discharge or at follow-up, and no difference was found in the mean head circumference between groups. A similar percentage of infants in each group was rehospitalized (38% Epo and 35% placebo/control) for similar reasons. There were no differences between groups with respect to the percentage of infants with Bayley-II Mental Developmental Index <70 (34% Epo and 36% placebo/control), blindness (0% Epo and 2% placebo/control), deafness or hearing loss requiring amplification (2% Epo and 2% placebo/control), moderate to severe cerebral palsy (16% Epo and 18% placebo/control) or the percentage of infants with any of the above-described neurodevelopmental impairments (42% Epo and 44% placebo/control). Treatment of ELBW infants with early Epo and iron does not significantly influence anthropometric measurements, need for rehospitalization, transfusions after discharge, or developmental outcome at 18 to 22 months' corrected age.

Obesity (OB), considered as one of the Non-Transmissible Chronic Diseases, has as its fundamental characteristics that of being prevalent at a global level, increasing in number, affecting developed and developing countries, affecting both genders, and all ages and social groups. To identify if high birth weight is a predictive factor (risk factor) for abdominal obesity in children 7 to 11 years old, and its relationship to gender, age and diet. A case-control descriptive study was carried out with children born between January 1992 and December 1995, in order to identify early risk factors (atherosclerotic accelerators) such as abdominal obesity in children aged 7 to 11, and who have a history of macrosomia or high birth weight, as well as their relationship with gender, age and diet. It was observed that the waist/height value was normal in 60.8% of the study group and in 64.00% in the control group. The difference between groups, gender, and age was not significant (P=.6859). As regards the diet in the study group (macrosomic), there was no significant association between the type of diet and waist circumference/height values, with an χ 2 =0.223 and P=.6373 (not significant). In the control group (with normal weight at birth), it was found that there is a significant statistical association between the type of diet and waist circumference/height values. This means that it can be stated, with 95% reliability, that the type of diet is associated with waist/height values. High birth weight is not a predictive factor (risk factor) for abdominal obesity (increased waist/height index). Gender and age are independent for abdominal obesity (macrosomic and normal weight at birth). The diet in high birth weight children is not related to the index waist-height index, which is not the case in those born with normal weight under the same conditions. The marked increase in abdominal obesity (Waist/height index) in children between 7 and 11 years old in both groups is worrying. Copyright © 2018 Sociedad Española de Arteriosclerosis.

Body height and weight are important indicators of children's health status. There are many evidences that children from disadvantaged families have lower height and weight than children of the same age from families without social risk. The aim of this study was to investigate characteristics of growth and development of children from economically disadvantaged families. The study was partly retrospective and partly prospective. The retrospective study included 509 children from disadvantaged families hospitalized at the Institute of Child and Adolescent Health Care in Novi Sad, during a five-year period. The prospective study included 90 children from disadvantaged families (experimental group) and 132 children from families without social risk (control group) hospitalized at the Institute during a six month period. Height/length, weight, head circumference, and psychomotor/intellectual development have been examined. In the retrospective study results were compared with theoretically expected values, whereas the prospective study results of experimental and control group were compared. In the retrospective study that included only children from disadvantaged families, 136 (26.7%) children had height/length, 173 (34%) had weight, and 86 (16.9%) children had head circumference below 10th percentile. Delay in psychomotor/intellectual development was established in 177 (34.8%) children. Children from families with social risk have significantly more often height/length, weight, head circumference and developmental delay than theoretically expected. In the prospective study 40 (44.4%) children from experimental group had height/length, 29 (32.2%) had weight, 20 (22.2%) children had head circumference below 10th percentile, and 17 (26.2%) had delay in psychomotor/intellectual development. Children from disadvantaged families (experimental group) significantly more often had delay in growth and development comparing with children from families without social risk (control group). Children from disadvantaged families significantly more often exhibit delay in growth and development, comparing with children of the same age from families without social risk. Therefore, pediatricians should consider social risk factors whenever treating children with growth or developmental delay.
