    2015-01-01

    This study presents a qualitative investigation of how Muslim Moroccan and Pakistani female immigrants living in Italy conceptualize their cultural identity. Ten Moroccan and 10 Pakistani (adolescent and adult) women were interviewed through in-depth semi-structured interviews. The interviewees expressed a strong attachment to their culture of origin: their religion is a crucial aspect of their identity, along with certain cultural rules and traditional values. At the same time, both Moroccan and Pakistani participants were ambivalent toward and experienced difficulties in developing a connection to the host country, although the two groups exhibit their lack of connection to their host country in different ways: Moroccans’ self-representation is marked by a sense of foreignness and by a lack of an emotional connection with places where they are living while Pakistanis tend to express cultural distance and conflict with the host culture’s values. For both the Moroccan and Pakistani groups, the challenge of integration and biculturalism seems demanding in the Italian context and is marked by a deep feeling of emptiness, a lack of an emotional bond with the new country, and a strong cultural ambivalence. Finally, narrative themes are articulated across four interrelated dimensions (cultural, religious, gendered, spatial), revealing interesting differences based on national origin and generation.

    Polycystic ovary syndrome (PCOS) is the major cause of anovulatory infertility. Although the genetic basis of PCOS is not well understood, it is a common metabolic and endocrine disorder. This study investigates the possible genomic variants associated with PCOS in Pakistani women from the Punjab region. DNA samples from 96 patients with genetically unrelated PCOS and 96 controls were analyzed by direct sequencing to determine the polymorphisms of different loci on follicle-stimulating hormone receptor (fshr), follicle-stimulating hormone β (fshrβ), luteinizing hormone chorionic gonadotropin (lhcgr), luteinizing hormone β (lhβ), estrogen receptor α (esr1), and estrogen receptor β (esr2) genes. Significant associations were observed within the genotype frequencies, allele frequencies, and multi-single-nucleotide polymorphism (SNP) haplotype analysis of most polymorphisms studied. This study identified new SNPs at positions 605+52 Del/T in lhcgr genes occurring in this particular subpopulation. The strong r (2) value suggests that polymorphisms in the fshr and esr1 genes were in linkage disequilibrium. Our study provides evidence of statistically significant associations between susceptibility to PCOS in Pakistani women and the gene polymorphisms mentioned earlier. This suggests that the susceptible loci for PCOS lie within or very close to the chromosomal regions spanning these genes. PMID:25100445

    2014-02-01

    Obesity is a common disorder affecting approximately 1 in 3 women. Assessment should consist of measuring BMI and waist circumference, a thorough history regarding nutrition, physical activity, and prior attempts at weight loss, and identification of obesity-related comorbidities. As a chronic disease, obesity requires management using a chronic care model employing multimodal therapy. Behavioral therapy to bring about changes in nutrition and physical activity can be supplemented with long-term use of medications (lorcaserin, orlistat, phentermine/topiramate) to help patients both achieve and maintain meaningful weight loss.

    Diseases of women that are due to their gender specific roles and responsibilities result from cultural and social factors prevalent in the environs. World Health Organization has put special emphasis on research need regarding gender related factors for diseases disproportionately affecting women in developing countries. The objective of this write up was to determine the prevalence of depression and the associated risk factors among adult women in Pakistan. PubMed was searched using key words depression, risk factors, women and Pakistan. Out of 20 initially retrieved articles, 12 were directly related to depression and its risk factors among Pakistani women within Pakistani geographical context. Women in Pakistan are vulnerable to poor mental health due to marriage related issues, domestic violence, verbal or physical abuse by in-laws, stressful life and poor social conditions. Women in their perinatal period are more at risk of depression due to pregnancy related concerns. PMID:23930875

    We undertook a cross-sectional study in rural Jehlum and urban Karachi to evaluate the prevalence of vitamin D deficiency in Pakistani pregnant women and neonates and to assess any association of serum 25(OH) vitamin D [25(OH)D] concentration with vitamin D binding protein (Gc) genotypes. Altogether, 390 women and 266 neonates were recruited from urban and rural sites, respectively. Serum 25(OH)D was measured by an immunoassay, while Gc genotypes were identified using polymerase chain reaction followed by restriction fragment length polymorphism or PCR-RFLP. One-way analysis of variance or ANOVA and linear regression were used for statistical analysis. In urban Karachi, 99.5% of women and 97.3% of neonates were vitamin D deficient (< 50 nmol/L), while 89% of women and 82% of neonates were deficient in rural Jehlum. Gc genotypes were not associated with serum 25(OH)D concentrations in both women and their neonates. We conclude that vitamin D deficiency is highly prevalent in Pakistani women and their neonates, and Gc genotypes are not associated with serum 25(OH)D concentrations. PMID:26466513

  12. Intimate partner violence against women and its related immigration stressors in Pakistani immigrant families in Germany

    PubMed Central

    2012-01-01

    This paper addresses the issue of intimate partner violence against women and its related immigration stressors in Pakistani immigrant families in Germany. Drawing on 32 in-depth interviews with Pakistani women in three cities in Germany, we found that psychological violence was the commonly reported violence among the study participants. The data showed that the process of immigration exacerbated tensions between spouses because of various immigration stressors such as threats to cultural identity, children’s socialization, and social isolation. In order to cope with the stressful spousal relations, women applied various indigenous strategies, but avoided seeking help from the host country’s formal care-providing institutions. This study also debunks some stereotypes and popular media clichés about the “victimhood of women from conservative developing countries” and provides an understanding of the issue of intimate partner violence within an immigration context. Further research with a larger sample will be helpful to understand immigration-induced stress and intimate partner violence in immigrant families. PMID:23984223

    The aim of the current study was to analyze the effect of six type II diabetes GWAS loci rs3923113 (GRB14), rs16861329 (ST6GAL1), rs1802295 (VPS26A), rs7178572 (HMG20A), rs2028299 (AP3S2) and rs4812829 (HNF4A), and an FTO polymorphism (rs9939609) on obesity. The probable mechanism of action of these SNPs was analyzed by studying their association with various biochemical and anthropometric parameters. A total of 475 subjects (obese=250, controls=225) were genotyped by TaqMan assay and their lipid profile was determined. Allele/genotype frequencies and an unweighted/weighted gene score were calculated. The effect of the gene score on anthropometric and biochemical parameters was analyzed. The minor allele frequencies of all variants were comparable to that reported in the original studies and were associated with obesity in these Pakistani subjects. Subjects with 9 risk alleles differ from those with <3 and overall there is no significant effect (P-value for trend 0.26). None of the SNPs were associated with any of the serum lipid traits. We are the first to report the association of these T2D SNPs with obesity. In the Pakistani population the reported effect of six SNPs for obesity is similar to that reported for T2D and having a combination of risk alleles on obesity can be considerable. The mechanism of this effect is unclear, but appears not to be mediated by changing serum lipid chemistry. PMID:26395551

    2016-03-01

    Postpartum obese women have an increased risk of breastfeeding difficulties and depression. Retaining the pregnancy weight at 6 months postpartum predicts long-term obesity. Risks for weight retention include excessive gestational weight gain, ethnicity, socioeconomic status, diet, exercise, depression, and duration of breastfeeding. Exercise and reducing total caloric intake promote postpartum weight loss. Intrauterine devices and contraceptive implants are the most effective contraceptives for obese women. Contraceptive pills, patches, and vaginal rings are effective options; however, obese women should be made aware of a potential increased risk of venous thromboembolism. Vasectomy and hysteroscopic sterilization carry the least surgical risk for obese women. PMID:26694498

    The prevalence of obesity and overweight are increasing and have become an epidemic worldwide. Obesity has detrimental influences on all systems, including reproductive health. The prevalence of obesity in infertile women is high, and it is well known that there is an association between obesity and infertility. The relationship between obesity and reproductive functions is still being explored. Overweight women have a higher incidence of menstrual dysfunction and anovulation. Overweight and obese women are at a high risk for reproductive health. The risk of subfecundity and infertility, conception rates, miscarriage rates, and pregnancy complications are increased in these women. They have poor reproductive outcomes in natural as well as assisted conception. These poor reproductive outcomes include assisted reproduction such as ovulation induction, in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI), and ovum donation cycles. Weight loss has beneficial effects on the reproductive outcomes in these patients. PMID:26097395

    The latter half of the twentieth century has witnessed rapid advances in cardiovascular epidemiology and medicine. Concurrently, secular trends in lifestyle practices and general improvements in standards of living have resulted in several alarming trends for cardiovascular disease prevention and health promotion. The adoption of unhealthy dietary patterns, growing socio-economic and racial disparities in chronic disease prevalence, low levels of physical activity, and other as yet unidentified genetic and environmental determinants have led to burgeoning rates of both pediatric and adult obesity and diabetes mellitus. Women appear to be at particular risk as the gender advantage for coronary heart disease (CHD) is counterbalanced by an increased incidence of obesity and diabetes. In order to further examine these complex associations, we review the available epidemiological data regarding the impact of obesity and diabetes on cardiovascular health in women. PMID:12478201

    Background Several developing countries like Pakistan step into Sustainable Development Goals period with crucial maternal and child health needs that need to be addressed for improving health outcomes among people. We aim to explore existent socio-economic disparities in use of family planning methods (FPM) among Pakistani women, and compare any such inequalities between the years 2006 and 2013. Setting Pakistan Demographic and Health Surveys (PDHS) 2006–7 (n = 9177) and the most recent 2012–13(n = 13558) data were used to conduct secondary analysis. Participants were ever married women aged between 15 and 49 years. Socio-economic status was assessed by the education level and wealth index. Inequalities were measured through Odds Ratio (OR), Relative Index of inequality (RII), and Slope index of inequality (SII) on non-use of FPM. Results Although the prevalence of FPM use has increased over time (28% in 2006 versus 54% in 2013), the socio-economic inequalities persistently exist. Comparing results of PDHS 2006 with PDHS 2013, education related absolute inequalities among urban dwellers increased from -0.41 (95% CI -0.67, -0.13, p-value < 0.01) to -0.83 (95% CI -1.02, -0.63, p-value < 0.01); and increased from -0.93 (95% CI -1.21, -0.64, p-value < 0.01) to -0.98 (95% CI -1.20, -0.76, p-value < 0.01) among rural dwellers. Similarly wealth related absolute inequalities are also existent. Conclusions Although the FPM use has increased over time, but it is important to note that socio-economic gap in use of FPM persists. Such differences have disadvantaged the poor and the illiterate. Family planning programs may target the disadvantaged subgroups for ensuring well-being of women and children in Pakistan.

    Objectives As a secondary analysis of the BEACHeS study, we hypothesised there would be sex differences in Pakistani and Bangladeshi school children when examining adiposity and their response to an obesity intervention. Design The Birmingham healthy Eating and Active lifestyle for CHildren Study (BEACHeS) was designed as a Phase II feasibility study of a complex intervention. Setting 8 primary schools with predominantly South Asian children in Birmingham, UK Participants 1090 pupils (aged 5–7 years old) from school year 1 and 2 were allocated at school level to receive an intervention. A total of 574 were enrolled in the study with consent. We focused on the 466 children of Pakistani and Bangladeshi origin (50.6% boys). Intervention Delivered between 2007 and 2009, the 1-year obesity prevention intervention targeted school and family-based dietary and physical activities. Primary and secondary outcome measures and analysis Adiposity measures including skinfold thickness were compared by sex at baseline and follow-up. Gains in adiposity measures were compared between control and intervention arms in boys and in girls. Measures were compared using two-sample t tests and Wilcoxon-Mann-Whitney rank sum tests according to normality distribution. Results At baseline, girls had larger skinfold measures at all sites compared to boys although body mass index (BMI) was similar (eg, median subscapular skinfold 6.6 mm vs 5.7 mm; p<0.001). At follow-up, girls in the intervention group gained less weight and adiposity compared to respective controls (p<0.05 for weight, BMI, waist circumference, central and thigh skinfold) with a median total skinfold gain of 7.0 mm in the control group compared to 0.3 mm in the intervention group. Conclusions Our secondary analysis suggests differences in adiposity in Pakistani and Bangladeshi girls and boys and in the effect of the intervention reducing adiposity in girls. These preliminary findings indicate that including sex

    The psychosocial impact of infertility is affected by cultural factors. In this cross-cultural qualitative study we explored the experience of infertility among six women living in Pakistan and eight living in the UK. Although infertile women in the UK and Pakistan had many shared experiences related to their own desires for motherhood and the hopes of others, they also faced unique psychosocial challenges shaped by cultural context. Based on our findings, we suggest a need for further resources and networks to support women, particularly women living in cultures that allow women few fulfilling social roles other than motherhood.

    Background There is no data on diet- and activity-related behaviors associated with overweight and obesity among Pakistani school-aged children. The study aimed to explore dietary behaviors, physical activity and sedentary lifestyle associated with overweight and obesity, and their socio-demographic correlates, among Pakistani primary school children. Methods A population-based cross-sectional study was conducted with a representative multistage random cluster sample of 1860 children aged five to twelve years in Lahore, Pakistan. Overweight (> +1 SD) and obesity (> +2 SD) were defined using the World Health Organization reference 2007. Chi-square test was used as the test of trend. Linear regression was used to examine the predictive power of independent variables in relation to body mass index (BMI). Logistic regression was used to quantify the independent predictors and adjusted odds ratios (aOR) with 95% confidence intervals (CI) were obtained. Statistical significance was considered at P < 0.05. Results Children skipping breakfast (8%), eating fast food and snacks ≥ once a week (43%) and being involved in sedentary lifestyle > one hour a day (49%) were significantly more likely to be overweight and obese while those participating in physical activity > twice a week (53%) were significantly less likely to be overweight and obese (all P < 0.01). Skipping breakfast (P < 0.001), eating fast food and snacks (P = 0.001) and sedentary lifestyle (P < 0.001) showed an independent positive association with BMI while physical activity showed an independent inverse association (P = 0.001). Skipping breakfast (aOR 1.82, 95% CI 1.22-2.71), eating fast food and snacks ≥ once a week (OR 1.41, 95% CI 1.07-1.86), physical activity > twice a week (aOR 0.49, 95% CI 0.34-0.70) and sedentary lifestyle > one hour a day (aOR 1.56, 95% CI 1.19-2.03) were independent predictors of being overweight. Skipping breakfast had independent inverse association with physical activity (aOR 0

    Obesity is characterized by increased adipose tissue mass resulting from a chronic imbalance between energy intake and expenditure. Furthermore, there is a clearly defined relationship among fat mass expansion, chronic low-grade systemic inflammation and reactive oxygen species (ROS) generation; leading to ROS-related pathological events. In the past years, genome-wide association studies have generated convincing evidence associating genetic variation at multiple regions of the genome with traits that reflect obesity. Therefore, the present study aimed to evaluate the relationships among the gene polymorphisms ghrelin (GHRL-rs26802), ghrelin receptor (GHSR-rs572169), leptin (LEP-rs7799039), leptin receptor (LEPR-rs1137101) and fat mass and obesity-associated (FTO-rs9939609) and obesity. The relationships among these gene variants and the amount of DNA damage were also investigated. Three hundred Caucasian morbidly obese and 300 eutrophic (controls) women were recruited. In summary, the results demonstrated that the frequencies of the GHRL, GHSR, LEP and LEPR polymorphisms were not different between Brazilian white morbidly obese and eutrophic women. Exceptions were the AA-FTO genotype and allele A, which were significantly more frequent in obese women than in the controls (0.23% vs. 0.10%; 0.46 vs. 0.36, respectively), and the TT-FTO genotype and the T allele, which were less frequent in morbidly obese women (p<0.01). Furthermore, significant differences in the amount of genetic lesions associated with FTO variants were observed only in obese women. In conclusion, this study demonstrated that the analyzed SNPs were not closely associated with morbid obesity, suggesting they are not the major contributors to obesity. Therefore, our data indicated that these gene variants are not good biomarkers for predicting risk susceptibility for obesity, whereas ROS generated by the inflammatory status might be one of the causes of DNA damage in obese women, favoring

    The health behaviours of pregnant women with very severe obesity are not known, though these women are at high risk of pregnancy complications. We carried out a prospective case-control study including 148 very severely obese (BMI >40 kg/m2) and 93 lean (BMI <25 kg/m2) pregnant women. Diet, physical activity, smoking, alcohol and folic acid consumption were assessed by questionnaire in early and late (16 and 28 weeks gestation) pregnancy. Circulating levels of iron, vitamin B12 and folate and other essential trace elements and minerals were measured in a subset at each time point. The findings biochemically confirmed that very severely obese women consumed diets that were energy-rich but poor in essential micronutrients. A third of all women met physical activity recommendations for pregnancy. A third of very severely obese women and two thirds of lean women took folic acid supplements prior to pregnancy. Very severely obese women were more likely to smoke but less likely to drink alcohol than lean women (all p < 0.05). Women with very severe obesity have low self-reported intakes and circulating levels of essential micronutrients in pregnancy and few follow current recommendations for pregnancy nutrition and lifestyle. These high-risk women represent a group to target for education about health behaviours prior to and during pregnancy. PMID:26457716

    No research has compared expressions of weight bias across different subgroups of obese individuals. This study compared attitudes toward and beliefs about obesity in women with and without binge eating disorder (BED) and examined whether these attitudes are related to psychological factors. Fifty obese women with BED were compared with an age- and body mass index (BMI)-matched group of 50 obese women without BED on a battery of established measures of anti-fat attitudes and beliefs about weight controllability and psychological factors (self-esteem, depression, and eating disorder features). The ageand BMI-matched groups did not differ with respect to beliefs about obesity or attitudes toward obese persons, or in self-esteem or depression. Correlational analyses conducted separately within each group revealed that women with BED who reported more favorable attitudes towards obese persons had higher self-esteem and lower levels of depression, whereas there were no significant associations between these variables among women without BED. In addition, weight controllability beliefs and eating disorder features were unrelated to self-esteem and depression in both groups. These findings suggest that stigmatizing attitudes endorsed by obese persons are neither tempered nor worsened by psychological distress or eating pathology. Given that stigmatizing attitudes did not differ between obese women with and without BED, it may be that obesity itself, rather than psychological features or disordered eating, increases vulnerability to negative weight-based attitudes. Potential implications for stigma reduction efforts and clinical practice are discussed. PMID:20124783

    Background Depression among women is common in developing countries. Gender inequality can contribute to women's risk for depression. Lack of reproductive and sexual rights is an important marker of gender inequality and women do not have the freedom to express their reproductive and sexual needs in many parts of the world. Therefore we designed this study to determine the association of depression with lack of various reproductive rights and domestic violence among married women in Karachi, Pakistan. Methods A case-control study with 152 cases and 152 controls, which included women 15-48 years, recruited from two teaching hospitals from 1st June 2007 through 31st August 2007. The SRQ was administered to all subjects. A cut off score of 8 was used to confirm cases of depression diagnosed by physicians, and to exclude cases of depression from the controls. Self-administered questionnaire was used to assess the risk factors. Results 61% of the cases and 43% of the controls were ever abused by spouse and the frequency of marital rape was 33% in cases and 13% in controls. After adjusting for the effects of other variables in the model, less than 18 years of age at marriage (OR 2.00; 95% CI = 1.07, 3.7), decision for marriage by parents (OR 3.51; 95% CI = 1.67, 7.37), abuse by in laws (OR 4.91; 95% CI = 2.66, 9.06), ≤ 3 hours per day spent with husband (OR 2.33; 95% CI = 1.34, 4.08), frequency of intercourse ≤ 2 times per week (OR 1.85; 95% CI = 1.06, 3.22) and marital rape (OR 3.03; 95% CI = 1.50, 6.11) were associated with depression among women. Conclusion In our study depression in married women was associated with younger age at marriage, lack of autonomy in marriage decisions, marital rape and domestic abuse by in-laws. Efforts should be directed towards creating awareness about the reproductive and sexual rights of women in Pakistan. Physicians should be trained to screen and identify women who may be at risk for psychological distress as a result of denial

    In the United States, adolescent obesity reduces young women's odds of forming romantic and sexual partnerships but increases the likelihood of risky sexual behavior when partnerships occur. This led us to conduct a study examining the relationship between adolescent obesity and adolescent childbearing. Our study has two aims. We draw from prior research to develop and test competing hypotheses about the association between adolescent obesity and young women's risk of an adolescent birth. Drawing from risk regulation theory, we also examine whether the association between obesity and young women's risk of an adolescent birth may vary across high schools with different proportions of obese adolescents. Multilevel logistic regression models are used to analyze data from 4242 female students in 102 U.S. high schools who participated in Wave I (1994-1995) of the National Longitudinal Study of Adolescent Health. Results are the first to show that obesity reduces female adolescents' odds of childbearing, but that this association is not uniform across schools with different proportions of obese students. As the obesity prevalence in a school increases, so do obese young women's odds of childbearing. We conclude that understanding whether and how obesity is associated with young women's odds of having an adolescent birth requires attention to the weight context of high schools. PMID:23702216

    The high rate of obesity among black women in the USA is a significant public health problem. However, there is limited research on the relationship between racial residential segregation and disparities in obesity, and the existing evidence is limited and results are mixed. This study examines the relationship between racial residential segregation and obesity among black and white women. We conducted this cross-sectional study by joining data from the 1999-2004 National Health and Nutrition Examination Survey with data from the 2000 US Census. Multilevel logistic regression models found that for every one-point increase in the black isolation index, there was a 1.06 (95 % confidence interval (CI) = 1.01, 1.11) times higher odds of obesity for black women. In order to address the disparately high rates of obesity among black women, health policies need to address the economic, political, and social forces that produce racially segregated neighborhoods.

    Background Type 2 diabetes (T2D) is a debilitating disease, highly prevalent in UK South Asians, and preventable by lifestyle intervention. The ‘New life, New you’ (NLNY) physical activity (PA) and dietary intervention for T2D prevention was culturally adapted to better engage minority ethnic populations and tested for feasibility. Objectives To investigate Pakistani female participants’ perspectives of their behaviour change and of salient intervention features. Setting A community-based 8-week programme of group delivered PA sessions with behavioural counselling and dietary advice, culturally adapted for ethnic minority populations, in an area of socioeconomic deprivation. Participants to NLNY were recruited through screening events in community venues across the town. Participants Interviews were conducted with 20 Pakistani female NLNY participants, aged 26–45 (mean 33.5) years, from different parts of town. Results Within the a priori Theoretical Domains Framework (intentions and goals, reinforcement, knowledge, nature of the activity, social role and identity, social influences, capabilities and skills, regulation and decision, emotion and environment), we identified the importance of social factors relating to participants’ own PA and dietary behaviour change. We also identified cross-cutting themes as collateral benefits of the intervention including participants’ ‘psychological health’; ‘responsibility’ (for others’ health, especially family members included in the new PA and diet regimes) and ‘inclusion’ (an ethos of accommodating differences). Conclusions Our findings suggest that culturally adapted interventions for Pakistani women at risk of T2D, delivered via group PA sessions with counselling and dietary advice, may encourage their PA and dietary behaviour change, and have collateral health and social benefits. The NLNY intervention appeared to be acceptable. We plan to evaluate recruitment, retention and likely effect of the

    The purpose of this study was to identify new indexes of body composition that characterize the normal weight obese (NWO) women. We measured body composition by dual energy x-ray absorptiometry (DXA) and resting metabolic rate (RMR) by indirect calorimetry in a cohort of seventy-five healthy Italian women, subdivided into three groups (nonobese/controls, NWO, preobese-obese women). Despite a normal body mass index (BMI), the NWO women have a higher body fat mass percentage (FAT %) (38.99 +/- 6.03) associated to a significant (p = 0.02) lower amount of lean mass of legs (12.24 +/- 1.31) and lean mass of left leg (6.07 +/- 0.64) with respect to the control group. The NWO group showed a significant (p = 0.043) lower RMR (1201.25 +/- 349.02) in comparison with nonobese and preobese-obese women. To classify NWO individuals among general population, we identified three significant body composition indexes: abdominal index, leg index and trunk index. The NWO women showed significant increased value in the three indexes (p < 0.001). Our results suggest that, despite a normal BMI, the NWO women displayed a cluster of anthropometric characteristics (body fat mass percentage, leg indexes) not different to obese women ones. An appropriate diet-therapy and physical activity may be protecting NWO individuals from diabetes and cardiovascular diseases associated to preobese-obese women. PMID:16910350

    High-energy diet and sedentary lifestyle fail to completely explain the epidemic of obesity in developing countries. In this cross-sectional survey, the prevalence and patterns of overweight/obesity were assessed among women in a slum in Brazil. Using anthropometric measurements, shorter form of the International Physical Activity Questionnaire (IPAQ), and a 24-hour diet recall questionnaire, data were collected from 632 women aged 20-60 years. The prevalence of overweight and obesity was 29% and 17% respectively. Physical inactivity was found in 17% of the women; 12% of them had short stature, and 44% had energy intake below the recommended dietary allowance. Results of multiple logistic regression showed that overweight/obesity differed significantly (p<0.05) in the following aspects: abdominal circumference, energy intake, and short stature. A high prevalence of overweight/obesity was found in a very poor community associated with high-energy intake and short stature. PMID:21766564

    Obese women are associated with clinical symptoms suggestive of abnormal reproductive functions including irregular menses and infertility. Previous studies of gonadotropin release in obese women, basal or after luteal hormone releasing hormone (LHRH) stimulation, are controversial. Obese women are also often characterized by glucose intolerance and hyperinsulinemia which might relate to their excessive body fat. To understand the link between abnormal gonadotropin release, carbohydrate metabolism and percent body fat, we examined 17 premenopausal morbid obese women with body mass index (BMI) 38.7 +/- 1.6 Kg/m2 (mean +/- SEM) and 16 age-matched lean controls with BMI 19.7 +/- 0.6 Kg/m2. Plasma glucose, insulin and C-peptide values were measured before and 30, 60, 90 and 120 min after a 75 gm oral glucose tolerant test (OGTT). Each individual also received LHRH test which involved determinations of serum LH and FSH values at basal, 15, 30 and 60 min after injection of LHRH for 0.1 mg intravenously. Women with morbid obesity had significantly greater responses of glucose, insulin and C-peptide values as compared with lean women (all p < 0.001, two-way ANOVA). Despite that basal concentrations were not different, serum LH, FSH and ratio of LH to FSH values in response to LHRH test showed significantly lesser increase in obese women than lean controls. Percent body fat, determined by bioelectrical impedance analysis, correlated positively with plasma glucose, insulin and C-peptide responses to OGTT while negatively with ratio of LH to FSH responses (r = -0.418, p < 0.01) to LHRH test. Body mass index also correlated inversely with ratio of LH to FSH responses (r = -0.472, p < 0.01). In conclusion, morbid obese women had glucose intolerance, hyperinsulinemia and lower responses of serum LH and FSH values as compared with lean women. Excessive body fat play an important role in mediating these carbohydrate and gonadotropin abnormalities. PMID:9551249

    Data from recent studies conducted in rodent models and humans suggest that interleukin-17A (IL-17A) plays a role in the induction of inflammation in adipose tissue during obesity. The aim of this study was to assess the gene expression of IL-17A in adipose tissue of morbidly obese patients. We used RT-PCR to evaluate the expression of IL-17A and several adipo/cytokines in the visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) of 10 normal-weight control women (BMI < 25 kg/m2) and 30 morbidly obese women (MO, BMI > 40 kg/m2). We measured serum levels of IL-17A and adipo/cytokines in MO and normal weight women. IL-17A expression was significantly higher in VAT than in SAT in MO patients (p = 0.0127). It was very low in normal-weight controls in both VAT and SAT tissues. We found positive correlations between IL-17A and IL-6, lipocalin-2 and resistin in VAT of MO patients. The circulating level of IL-17A was higher in the normal-weight group than the MO patients (p = 0.032), and it was significantly related to adiponectin and TNFRII levels. In conclusion, IL-17A expression in VAT is increased in morbidly obese women, which suggests a link between obesity and innate immunity in low-grade chronic inflammation in morbidly obese women.

    Background/Objective. Obesity has become a global epidemic due to an increase in the number of obese individuals worldwide. There is little research in the field of obesity genetics in Pakistan. The aim of the current study was to analyze the association of common variants in Fat Mass and Obesity associated (FTO) gene with obesity in Pakistan, to find out the effect of the selected SNPs on anthropometric and biochemical traits, and to observe whether these variants act synergistically. Methods. Samples from 631 subjects were taken after informed consent and were used for serum parameters and genetic analysis. Lipid profile was determined, tetra-ARMS PCR was used for genotyping, and allele/genotype frequencies and genescore were calculated. Results. All FTO variants were associated with obesity, and some biochemical and anthropometric measures and had higher minor allele frequencies than those reported for Asian populations previously. The risk allele of each single nucleotide polymorphism resulted in an increase in BMI in a quantitative manner. Conclusion. Common forms of obesity are due to a combined net effect of many variants presented in same or different genes. The more the number of risk alleles present, the higher the risk and severity of obesity resulting from an increase in BMI. PMID:26357660

    We evaluated pregnancy outcomes in obese women with excessive weight gain during pregnancy. A retrospective study was performed on all obese women. Outcomes included rates of preeclampsia (PEC), gestational diabetes, cesarean delivery (CD), preterm delivery, low birth weight, very low birth weight, macrosomia, 5-minute Apgar score of <7, and neonatal intensive care unit (NICU) admission and were stratified by body mass index (BMI) groups class I (BMI 30 to 35.9 kg/m(2)), class II (36 to 39.9 kg/m(2)), and class III (>or=40 kg/m(2)). Gestational weight change was abstracted from the mother's medical chart and was divided into four categories: weight loss, weight gain of up to 14.9 pounds, weight gain of 15 to 24.9 pounds, and weight gain of more than 25 pounds. A total 20,823 obese women were eligible for the study. Univariate analysis revealed higher rates of preeclampsia, gestational diabetes, Cesarean deliveries, preterm deliveries, low birth weight, macrosomia, and NICU admission in class II and class III obese women when compared with class I women. When different patterns of weight gain were used as in the logistic regression model, rates of PEC and CD were increased. Excessive weight gain among obese women is associated with adverse outcomes with a higher risk as BMI increases. PMID:20013581

    Objectives To describe the design and baseline population characteristics of an adapted lifestyle intervention trial aimed at reducing weight and increasing physical activity in people of Indian and Pakistani origin at high risk of developing type 2 diabetes. Design Cluster, randomised controlled trial. Setting Community-based in Edinburgh and Glasgow, Scotland, UK. Participants 156 families, comprising 171 people with impaired glycaemia, and waist sizes ≥90 cm (men) and ≥80 cm (women), plus 124 family volunteers. Interventions Families were randomised into either an intensive intervention of 15 dietitian visits providing lifestyle advice, or a light (control) intervention of four visits, over a period of 3 years. Outcome measures The primary outcome is a change in mean weight between baseline and 3 years. Secondary outcomes are changes in waist, hip, body mass index, plasma blood glucose and physical activity. The cost of the intervention will be measured. Qualitative work will seek to understand factors that motivated participation and retention in the trial and families’ experience of adhering to the interventions. Results Between July 2007 and October 2009, 171 people with impaired glycaemia, along with 124 family volunteers, were randomised. In total, 95% (171/196) of eligible participants agreed to proceed to the 3-year trial. Only 13 of the 156 families contained more than one recruit with impaired glycaemia. We have recruited sufficient participants to undertake an adequately powered trial to detect a mean difference in weight of 2.5 kg between the intensive and light intervention groups at the 5% significance level. Over half the families include family volunteers. The main participants have a mean age of 52 years and 64% are women. Conclusions Prevention of Diabetes & Obesity in South Asians (PODOSA) is one of the first community-based, randomised lifestyle intervention trials in a UK South Asian population.

Moreover, a significant percentage of women have weight retention in the postpartum period, especially those with excessive weight gain during pregnancy. The recommendations of the 2009 Institute of Medicine were based on observational studies that have consistently shown that women with weight gain within the recommended range had better outcomes during pregnancy. In patients with obesity, however, there is no recommendation for weight gain, according to the class of obesity.

A follow-up survey was conducted of 325 ever-married women aged 20–54 years, systematically selected from 1998–99 National Family Health Survey samples, who were re-interviewed after 4 years in 2003. Information on day-to-day problems, body image dissatisfaction, sexual dissatisfaction, and stigma and discrimination were collected and anthropometric measurements were obtained from women to compute their current body mass index. Three out of four overweight women (BMI between 25 and 29.9 kg/m2) were not happy with their body image, compared to four out of five obese women (BMI of 30 kg/m2 or greater), and almost all (95 percent) morbidly obese women (BMI of 35 kg/m2 or greater) (p < .0001). It was found that morbidly obese and obese women were five times (adjusted odds ratio [aOR] 5.29, 95% confidence interval [CI] 2.02–13.81, p < .001) and two times (aOR 2.30, 95% CI 1.20–4.42, p < .001), respectively, as likely to report day-to-day problems; twelve times (aOR 11.88, 95% CI 2.62–53.87, p < .001) and three times, respectively, as likely (aOR 2.92, 95% CI 1.45–5.88, p = .001) to report dissatisfaction with body image; and nine times (aOR 9.41, 95% CI 2.96–29.94, p < .001) and three times (aOR 2.93, 95% CI 1.03–8.37, p = .001), respectively, as likely to report stigma and discrimination as overweight women.

    The nutrition transition is associated with increased obesity rates and increased desire to be thin. This study evaluates the relationship between actual body size and desired body size among a representative sample of 800 Jordanian women. Using Stunkard's body silhouettes, women were asked to identify their current and ideal body sizes, healthy body size, and their perception of the body size preferred by men. Body mass index (BMI) calculations indicate that 53.8% of the women were overweight or obese. Their mean current body size was 5, which is consistent with the mean BMI of 26 in the sample. Although 66% of the women were dissatisfied with their body size, the desired weight loss was not extreme. Pearson correlation was positive (.858, p <.0001) between measured BMI and body silhouettes chosen as an indicator of current body size. Jordanian women seemed pulled between the traditional and Westernized body preferences. Possible cultural explanations are explored. PMID:21169479

    To determine impact of obesity on recovery parameters and pulmonary functions of women undergoing major abdominal gynecological surgeries. Eighty women undergoing major gynecological surgeries were included in this study. Anesthesia was induced by remifentanil bolus, followed by propofol and cisatracurium to facilitate oro-tracheal intubation and was maintained by balanced anesthesia of remifentanil intravenous infusion and sevoflurane in oxygen and air. Time from discontinuation of maintenance anesthesia to fully awake were recorded at 1-min intervals and time from discontinuation of anesthesia until patient was transferred to post-anesthesia care unit (PACU) and discharged from PACU was also recorded. Pulmonary function tests were performed before surgery and repeated 4 h, days 1, 2 and 3 post-operative for evaluation of forced vital capacity, forced expiratory volume in 1 s and peak expiratory flow rate. Occurrence of post-operative complications, re-admission to ICU, hospital stay and morbidities were also recorded. Induction of anesthesia using remifentanil bolus injection resulted in significant decrease of heart rate and arterial pressures compared to pre-operative and pre-induction values. Recovery times were significantly shorter in obese compared to morbidly obese women. Post-operative pulmonary function tests showed significant deterioration compared to pre-operative measures but showed progressive improvement through first 3 post-operative days. Hospital stay was significantly shorter for obese compared to morbid obese women. Obesity delays recovery from general anesthesia, adversely affects pulmonary functions and increases post-operative complications. Remifentanil infusion and sevoflurane could be appropriate combination for obese and morbidly obese women undergoing major surgeries. PMID:26072156

    Ramadan fasting can be considered as a kind of dietary restriction. Eating restriction is a risk factor for later development of eating disorders. The purpose of this study is to evaluate whether Ramadan fasting changes the eating behaviours of obese women. Our sample consisted of 34 obese women who fasted during the Ramadan month. The data were collected by using Questionnaire Form, Eating Attitude Test (EAT) and Bulimic Investigatory Test, Edinburgh (BITE). No statistically significant differences were found between the scores of EAT, BITE, BMI, which were administered within the weeks before and after Ramadan. According to our results, Ramadan fasting restrictions do not seem to change the eating behaviours of obese women. PMID:22576675

    AIM: Study the association between the total caloric intake, protein, lipid, and some classes of fatty acids of the diet, and their effects on blood pressure in a sample of Egyptian obese women with and without visceral obesity. METHODS: Five hundred forty-nine obese women were included in the study with mean age of 38.1 ± 11.56 years and mean Body mass index [BMI] of 36.17 ± 7.23. They enrolled in a program for losing weight. Visceral fat was determined using ultrasound. Blood pressure was measured 3 times and the mean was recorded. Twenty four hours dietary recall was reported. RESULTS: Thirty point four percentages of samples has visceral obesity ≥ 7cm; they were the older, showed higher values of BMI, visceral obesity and blood pressure. Significant difference was found between groups regarding mean value of BMI, visceral obesity, both systolic blood pressure SBP and diastolic blood pressure DBP and most of the daily macronutrients intake. In groups (2&3) positive significant correlation was recorded between (SBP) & (DBP) and total daily intake of total calories, carbohydrate, total fat, saturated fatty acids and cholesterol, and negative significant correlation with total daily intake of total protein, animal and vegetable protein, linolenic and linoleic fatty acids, while oleic fatty acid showed negative correlation with SBP&DBP in all groups. CONCLUSION: This study emphasizes the hypothesis that the macronutrients composition of diet influences blood pressure in different ways, in obese patients with visceral obesity. PMID:27275219

    The levonorgestrel intrauterine device (LNG-IUD) is a safe, effective, long-acting, reversible contraceptive that reduces unintended pregnancy and decreases heavy menstrual bleeding. Many procedures such as IUD insertion are more challenging in overweight and obese women. The objective of this study was to describe LNG-IUD insertion, continuation, and complications in overweight and obese women in an ethnically diverse population in Hawai‘i. A retrospective cohort study of women who had a LNG-IUD inserted at the University of Hawai‘i, Department of Obstetrics and Gynecology Resident and Faculty practice sites between January 2009 and December 2010 was performed. A total of 149 women were followed. The most commonly reported races were Asian (32%), Native Hawaiian (26%), and non-Hawaiian Pacific Islander (20%). The mean BMI of the study population was 28.4 (standard deviation 7.2) with 37% classified as normal weight, 30% as overweight, and 33% as obese. Overall, 76% of women continued the LNG-IUD 12 months after insertion. No statistically significant difference emerged in 12-month IUD continuation between the BMI groups. Difficult (5%) and failed (3%) IUD insertions were rare for all BMI groups. IUD complications occurred in 9% of women and included expulsion and self-removal. In this diverse population, the majority of women continued to use the LNG-IUD one year after insertion with low rates of difficult insertions and complications. PMID:26568900

    STUDY QUESTION Are certain ethnic groups with polycystic ovary syndrome (PCOS) at increased risk of metabolic disorders? SUMMARY ANSWER Obese Hispanic women with PCOS are at increased risk of metabolic disorders compared with age- and BMI-matched obese non-Hispanic white women with PCOS in the USA. WHAT IS KNOWN ALREADY Ethnic differences in body composition and metabolic risk are well established. PCOS is a common disorder in women of reproductive age and is associated with high rates of insulin resistance, glucose intolerance and dyslipidemia. STUDY DESIGN, SIZE, DURATION A cross-sectional observational study was performed at an Academic Medical Center on 60 women of reproductive age with PCOS. PARTICIPANTS/MATERIALS, SETTING, METHODS Blood was obtained after fasting from 17 Hispanic, 22 non-Hispanic black and 21 non-Hispanic white women with PCOS who were similar in age and BMI. Anthropometric parameters, insulin, lipid and lipoprotein levels (measured by nuclear magnetic resonance) were compared between the three groups. MAIN RESULTS AND THE ROLE OF CHANCE Age and BMI did not differ between the groups. Hispanic women with PCOS had higher waist-to-hip ratio (WHR) (P = 0.02), homeostasis model assessment of insulin resistance (HOMA-IR) (P = 0.03) and a more atherogenic lipid and lipoprotein profile consisting of lower high-density lipoprotein (HDL) (P = 0.02), higher low-density lipoprotein (LDL) particle number (P = 0.02), higher very low-density lipoprotein particle (VLDL) size (P = 0.03) and lower LDL (P = 0.03) and HDL particle size (P = 0.005) compared with non-Hispanic white women. The differences in HDL, HOMA-IR, VLDL and LDL size did not persist after adjustment for WHR while differences in LDL particle number (P = 0.04) and HDL size (P = 0.01) persisted. LIMITATIONS, REASON FOR CAUTION The sample size for the three groups was small but the findings were still significant. The women were mostly obese so the ethnic differences in metabolic disorders may

    Non-Hispanic African-American women have the highest incidence of overweight in the United States, at 48%. For non-Hispanic white females, the prevalence is 32.9%. This striking difference can be expected to have a great impact on morbidity and mortality within this culture. The purpose of this study is to ascertain, by descriptive analysis of data derived from a questionnaire, whether there are modifiable factors specific to African-American women that could lead to an increased prevalence of obesity. Forty adult, African-American obese women were given a questionnaire covering personal socioeconomics, dietary habits, educational level, exercise patterns, childhood exposures, and stress management. Data from the questionnaire were grouped and collated to determine whether specific trends could be discerned. This descriptive evaluation found that hair care issues had some effect on exercise patterns. In addition, a lack of childhood role models for exercise and an adult pattern of sedentary lifestyles appeared to be significant factors contributing to obesity. After this pilot study, a comparative study with a white group of obese women or a group of nonobese African-American women should be the next step in evaluation to further define and understand these observations.

    Leptin is a protein hormone synthesized by adipocytes and is involved in the regulation of food intake and energy expenditure. We hypothesized that any change in the promoter sequence can affect the expression of the gene and hence leptin protein levels in the serum. The aim of the current study was to investigate the relationship of such a promoter variant of the leptin gene, G-2548A polymorphism, with obesity and its effect on various anthropometric and metabolic parameters in a Pakistani cohort consisting of 250 obese and 225 non-obese control subjects. Body weight, height, waist circumference (WC), hip circumference (HC) and blood pressure (BP) were measured by standard methods and levels of fasting blood glucose (FBG), total cholesterol, triglycerides, HDLC, LDLC, and leptin were determined. Genotyping was done by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The results showed that the LEP G-2548A polymorphism showed significant association with obesity in Pakistan. In addition, the polymorphism showed association with weight, height, BMI, WC, HDLC and serum leptin levels. The findings suggest that the leptin promoter G-2548A variant may play its part in the progression to obesity by not only affecting the body's fat distribution but also by changing the serum leptin and HDLC levels.

    The present study assessed food cravings in a cohort of 229 women who differed in smoking history (i.e., never smoker, former smoker, and current smoker) and body weight (i.e., normal weight, overweight, and obese). Each subject completed the Food Craving Inventory (FCI), which measures cravings for sweets, high fats, carbohydrates/starches, and fast-food fats, and the Profile of Mood States (POMS), which measures psychological distress. Smoking and obesity were independently associated with specific food cravings and mood states. Current smokers craved high fats more frequently than former and never smokers. They also craved starches more frequently and felt more depressed and angry than never smokers, but not former smokers. Whereas cravings for starchy foods and some mood states may be characteristic of women who are likely to smoke, more frequent cravings for fat among smokers is related to smoking per se. Similarly, obese women craved high fats more frequently than nonobese women and depression symptoms were intensified with increasing body weights. We hypothesize that the overlapping neuroendocrine alterations associated with obesity and smoking and the remarkable similarities in food cravings and mood states between women who smoke and women who are obese suggest that common biological mechanisms modulate cravings for fat in these women.

    2016-01-01

    We aimed to determine the prevalence and bother from pelvic floor disorders (PFD) by obesity severity, hypothesizing that both would increase with higher degrees of obesity. We performed a secondary analysis of 1,155 females enrolled in an epidemiologic study that used a validated questionnaire to identify PFD. Prevalence and degree of bother were compared across three obesity groups. Logistic regression assessed the contribution of degree of obesity to the odds of having PFD. Prevalence of any PFD was highest in morbidly (57%) and severely (53%) obese compared to obese women (44%). Regression models demonstrated higher prevalence of pelvic organ prolapse, overactive bladder, stress urinary incontinence, and any PFD in morbidly compared to obese women and higher prevalence of stress urinary incontinence in severely obese compared to obese women. Degree of bother did not vary by degree of obesity. Prevalence of PFD increases with higher degrees of obesity. PMID:19002365

    This article provides evidence of a culturally specific dance intervention to decrease obesity as measured by body fat and body mass index (BMI) in African American women. A community partnership was formed with two African American churches to develop an intervention to address the issue of obesity. The culturally specific dance intervention was delivered two times per week for 8 weeks, choreographed to gospel music selected by the experimental group participants, and taught by an African American woman. Body fat and BMI were assessed at three time points and revealed significant differences between the two groups. Attending a minimum of 7 classes was enough to show an observed dose effect and the intervention was found to be culturally specific by understanding their roles as African American women. This community partnership was an effective way to promote a church-based, culturally specific dance intervention to improve the health of African American women. PMID:19098267

    This study uses segmentation analyses to identify five distinct subgroups of U.S. midlife women (n = 200) based on their prevailing attitudes toward food and its preparation and consumption. Mean age of the women is 46 years and they are mostly White (86%), highly educated, and employed. Attitude segments (clusters of women sharing similar attitudes) are a significant predictor of obesity indicators. Mean body mass index and percentage of body fat are lower for the "concerned about nutrition" attitude segment compared with the "guiltridden dieter" and "impulsive eater" attitude segments. Mean waist circumference is highest in "impulsive eater" compared with the "concerned about nutrition" segment. Those in the "busy cooking avoider" segment have a significantly higher energy intake compared with women in other attitude segments. Tailoring a weight management intervention according to attitude segments of midlife women may enhance effectiveness. PMID:19797540

    Abstract The object of this study was to assess the obesity in postmenopausal women, according to age at childbirth. We analyzed the association between age at first childbirth, age at last childbirth, parity, and subject obesity status (general obesity; BMI >25 kg/m2, nongeneral obesity; BMI ≤25 kg/m2, abdominal obesity; waist circumference >85 cm, nonabdominal obesity; waist circumference ≤85 cm), using data from a nationwide population-based survey, the 2010 to 2012 Korean National Health and Nutrition Examination Survey. Data from a total of 4382 postmenopausal women were analyzed using multivariate regression analysis with complex survey design sampling. And, the subjects were subdivided into groups according to obesity or not. Age, smoking, alcohol consumption, exercise, education, income level, number of pregnancies, oral contraceptive uses, breast feeding experience were adjusted as the confounders. The prevalence of general obesity among Korean postmenopausal women was 37.08%. Women with general obesity and abdominal obesity were significantly younger at first childbirth compared with women with nongeneral obesity and no abdominal obesity (23.89 ± 0.1 vs. 23.22 ± 0.1, P <0.001). Age at first childbirth was inversely associated with obesity, while age at last childbirth was not associated with obesity or abdominal obesity. Women with a higher number of pregnancies were also more likely to have obesity and abdominal obesity. Age at first childbirth remained significantly associated with obesity, after adjusting for confounding factors. Obesity in postmenopausal women is associated with first childbirth at a young age, and higher parity. Further research is needed to clarify the association between obesity and reproductive characteristics. PMID:27175656

    The problem of obesity affects all age groups. It is also observed among menopausal women. Menopause is the time in a woman's life when, as a consequence of hormonal changes occurring in the body, the risk of overweight and obesity increases significantly and, therefore, so does the risk of metabolic and cardiovascular diseases. Excess body weight in menopausal women may also be of social and psychological importance since the occurring symptoms may considerably decrease quality of life and sexual activity of these women. Reduction of body weight in obese menopausal women should play a vital role in treatment of this group of patients. Therefore, adequate management seems to be essential, and it should involve dietary, pharmacological and/or surgical treatment, depending on the patient's needs. Following a rational weight loss plan provided by a dietician under medical supervision may contribute to improvement of the health condition and quality of life. It is recommended to observe the guidelines on dietary management described in this article by adjusting a diet plan individually. The following work constitutes a review of articles from 2004-2014 which are available in the PubMed medical knowledge base and the Polish Medical Bibliography (Polska Bibliografia Lekarska). For this purpose, the following controlled vocabulary has been used: menopausal woman, menopausal diet, menopausal weight gain, menopausal weight loss, dietary management in menopause. PMID:26327888

    2010-01-01

    Study Objectives: The aim was to assess associations between sleep duration, sleep stages, and central obesity in women. Design: Cross-sectional study. Setting: City of Uppsala, Sweden. Participants: Population-based sample of 400 women (range 20-70 years). Interventions: Full-night polysomnography and measurement of anthropometric variables. Measurements and Results: Sleep duration was inversely related to both waist circumference and sagittal abdominal diameter. Sleep duration remained inversely related to waist circumference (adj. β = −1.22 cm/h; P = 0.016) and sagittal abdominal diameter (adj. β = −0.46 cm/h; P = 0.001) after adjusting for potential confounders. Duration of slow wave sleep (SWS, adj. β = −0.058 cm/min; P = 0.025) and REM sleep (adj. β = −0.062 cm/min; P = 0.002) were both inversely related to waist circumference after adjustments. Moreover, duration of REM sleep was inversely related to sagittal abdominal diameter (adj. β = −0.021 cm/min; P < 0.0001). These associations were stronger in young women (age < 50 years). Conclusion: An inverse relationship between short sleep duration and central obesity was found in women after adjusting for confounders. Loss of SWS and REM sleep may be important factors in the association between sleep loss and central obesity. Citation: Theorell-Haglöw J; Berne C; Janson C; Sahlin C; Lindberg E.

    Obesity is a major public health concern, and obesity among women of childbearing age can have a negative impact on fertility. The mechanism of action between obesity and infertility is complex and includes hormonal factors, alterations in ovulation, and changes in the menstrual cycle. Maternal obesity has also been linked to spontaneous abortion and poorer maternal and fetal health outcomes. Many interventions exist to help childbearing women achieve a lower body mass index. These include lifestyle modifications (diet/physical activity) and surgical and pharmacologic interventions. This article reviews the pathophysiology of the relationship between obesity and infertility and discusses evidence-based interventions for improving fertility among obese childbearing women.

    During submaximal exercise, some otherwise healthy obese women experience breathlessness, or dyspnea on exertion (+DOE), while others have mild or no DOE (-DOE). We investigated whether weight loss could reduce DOE. Twenty nine obese women were grouped based on their Ratings of Perceived Breathlessness (RPB) during constant load 60 W cycling: +DOE (n = 14, RPB ≥ 4, 34 ± 8 years, and 36 ± 3 kg/m(2)) and -DOE ( n= 15, RPB ≤ 2, 32 ± 8 years, and 36 ± 4 kg/m(2)) and then completed a 12-week weight loss program. Both groups lost a moderate amount of weight (+DOE: 6.6 ± 2.4 kg, -DOE: 8.4 ± 3.5 kg, and p < 0.001). RPB decreased significantly in the +DOE group (from 4.7 ± 1.1 to 3.1 ± 1.6) and remained low in the -DOE (from 1.5 ± 0.7 to 1.6 ± 1.1) (interaction p < 0.002). Most physiological variables measured (i.e. body composition, fat distribution, pulmonary function, oxygen cost of breathing, and cardiorespiratory measures) improved with weight loss; however, the decrease in RPB was not correlated with any of these variables (p > 0.05). In conclusion, moderate weight loss was effective in reducing breathlessness on exertion in obese women who experienced DOE at baseline. PMID:25220695

    Abstract Background: Obese women are at high risk of early breastfeeding cessation, and health professionals (HPs) have a unique opportunity to provide them with breastfeeding support. Our objective was to describe HPs' experiences providing breastfeeding care for obese women during the prenatal, peripartum, and postpartum periods. Materials and Methods: In-depth, qualitative interviews were conducted with 34 HPs (including obstetricians, midwives, pediatricians, nurses, and lactation consultants) who care for pregnant or lactating women. They were recruited from a variety of settings in central New York. Interviews were audio-recorded, transcribed, verified for accuracy, and then analyzed qualitatively. Results: HPs identified obesity in multiple ways, some of which were consistent with standard cutoffs, whereas others implied extreme obesity. Nearly all HPs discussed ways they perceive obese women have challenges with breastfeeding. Some HPs described challenges as specific to obese women (e.g., limited mobility), whereas others described challenges as universal but more likely to occur among obese women (e.g., difficulties positioning the infant to breastfeed). Across professions, HPs described providing breastfeeding care for obese women as requiring more time and physical work and as being more challenging. HPs acknowledged stigma around obesity and discussed treating obese women with dignity and the same as other women. Strategies were suggested for improving breastfeeding support for obese women. Conclusions: HPs identified multiple challenges that obese women encounter with breastfeeding, as well as their own challenges with providing care. Comprehensive strategies are needed to assist obese women with breastfeeding and to alleviate strain on HPs who provide their care. PMID:25347705

    Objective To determine the prevalence of sarcopenia in a population of obese older women and to assess the effect of a diet moderately rich in proteins on lean mass in sarcopenic obese older women. Materials and methods A total of 1,030 females, >65 years old, body mass index >30 kg/m2, were investigated about their nutritional status. Muscle mass (MM) was estimated according to the Janssen equation (MM =0.401× height2/resistance measured at 50 kHz +3.825× sex −0.071× age +5.102). Sarcopenia was defined according to the MM index, MM/height2 (kg/m2), as two standard deviations lower than the obesity-derived cutoff score (7.3 kg/m2). A food-frequency questionnaire was used to measure participants’ usual food intake during the previous 3 months. Moreover, a group of sarcopenic obese older women (n=104) was divided in two subgroups: the first (normal protein intake [NPI], n=50) administered with a hypocaloric diet (0.8 g/kg desirable body weight/day of proteins), and the second treated with a hypocaloric diet containing 1.2 g/kg desirable body weight/day of proteins (high protein intake [HPI], n=54), for 3 months. Dietary ingestion was estimated according to a daily food diary, self-administered, and three reports of nonconsecutive 24-hour recall every month during the follow-up. Results The 104 women were classified as sarcopenic. After dieting, significant reductions in body mass index were detected (NPI 30.7±1.3 vs 32.0±2.3 kg/m2, HPI 30.26±0.90 vs 31.05±2.90 kg/m2; P<0.01 vs baseline). The MM index presented significant variations in the NPI as well as in the HPI sarcopenic group (NPI 6.98±0.1 vs 7.10±0.2 kg/m2, HPI 7.13±0.4 vs 6.96±0.1 kg/m2; P<0.01 vs baseline). Conclusion A diet moderately rich in proteins was able to preserve MM in sarcopenic women. Therefore, adequate protein intake could contribute to the prevention of lean-mass loss associated with weight reduction in obese older people. PMID:26917955

    OBJECTIVE AND AIM: Most studies have detected impairment of gallbladder motility among obese compared with nonobese people. However, the relationship between gallbladder motility and weight loss is not well defined. The aim of this study was to evaluate the relationship between percent of weight loss and gallbladder motility during weight-reducing programs in obese women. PATIENTS AND METHODS: Thirty-four premenopausal obese women (body mass index >30 kg/m2) were included in the study. Following an overnight fast, fasting and postprandial 15-, 30-, 45-, 60-, 75-, 90-, 120- and 150th-minute gallbladder volumes and ejection fractions were evaluated with real-time ultrasonography as baseline and repeated after sixth months of weight-reducing programs. The lowest postprandial gallbladder volume was accepted as the residual volume. Gallstone formation was found in three (8.8%) patients during the study period, and these patients were dropped out. Thirty-one obese women were divided into three groups based on weight loss percent (group 1: 11 patients, weight loss <5%; group 2: 10 patients, weight loss 5-10%; group 3: 10 patients, weight loss >10%). RESULTS: Fasting gallbladder volume and all ejection fractions were not significantly different between baseline and after sixth months in all groups (p>0.05). Residual volume was decreased after sixth months in only group 3 (p=0.005). Difference of fasting and residual volumes, and ejection fractions at baseline and after sixth months was similar in all groups (p>0.05). There was a positive correlation between weight loss and the change of residual volume (r=0.395, p=0.028). CONCLUSION: Our findings suggest no relationship between degree of weight loss and ejection fraction. However, decreased residual volume and late-phase gallbladder volumes indicate gallbladder motility changing in patients who had >10% weight loss. PMID:17052060

    Objective: Subcutaneous (SC) adipose tissue stearic acid (18:0) content and stearoyl-CoA desaturase-1 (SCD1)-mediated production of oleic acid (18:1) have been suggested to be altered in obesity. The objective of our study was to examine abdominal adipose tissue fatty acid content and SCD1 mRNA/protein level in women. Subjects and methods: Fatty acid content was determined by capillary gas chromatography in SC and omental (OM) fat tissues from two subgroups of 10 women with either small or large OM adipocytes. Samples from 10 additional women were used to measure SCD1 mRNA and protein expression, total extracellular signal-regulated kinase 1/2 (ERK1/2) and phosphorylated ERK1/2 protein as well as insulin receptor (IR) expression levels. Results: OM fat 18:0 content was significantly lower in women with large OM adipocytes compared with women who had similar adiposity, but small OM adipocytes (2.37±0.45 vs 2.75±0.30 mg per 100 g adipose tissue, respectively, P⩽0.05). OM fat 18:0 content was negatively related to the visceral adipose tissue area (r=−0.44, P=0.05) and serum triglyceride levels (r=−0.56, P<0.05), while SC fat 18:0 content was negatively correlated with total body fat mass (BFM) (r=−0.48, P<0.05) and fasting insulin concentration (r=−0.73, P<0.005). SC adipose tissue desaturation index (18:1/18:0), SCD1 expression and protein levels were positively correlated with BFM. Moreover, obese women were characterized by a reduced OM/SC ratio of SCD1 mRNA and protein levels. A similar pattern was observed for ERK1/2 and IR expression. Conclusion: The presence of large adipocytes and increased adipose mass in a given fat compartment is related to reduced 18:0 content and increased desaturation index in women, independently of dietary fat intake. The depot-specific difference in ERK1/2 expression and activation, as well as in SCD1 and IR expression in obese women is consistent with the hypothesis that they may predominantly develop SC fat, which

    A series of untrained, healthy, obese women (body mass index 32.5 +/- 0.9 kg.m-2) were subjected to a protocol of intense exercise on a cycloergometer and compared with lean controls (body mass index 20. 9 +/- 0.5 kg.m-2). Physiological parameters, blood lactate, bicarbonate, plasma metabolites, oxygen consumption and CO2 production were measured. Impedance-derived extracellular water and plasma changes in lactate and bicarbonate were used to determine changes in bicarbonate pools and lactate-displaced CO2. From these and respiratory gases, the respiratory quotient was calculated and thence overall fuel consumption. Anaerobic energy during exercise accounted for about 1.8% of all energy consumed in the lean but only 0.7% in the obese. Obese women fatigued at lower workloads and energy expenditure levels than did the lean, and their lactate buildup was similar when compared on the basis of fat-free mass. The data support the postulation of fatigue being triggered by a combination of factors: stretched cardiovascular work would be the main factor for obese women, in part limiting lactate production. For lean women, the triggering factor for fatigue could be the loss of buffering capacity; but it is the combination of stretching cardiovascular capacity, exhaustion of glycogen and available glucose and increase in lactate/loss of bicarbonate buffer that determines the onset of fatigue.

    The use of laparoscopic surgery in the management of gynaecological malignancies has been growing for over a decade. Concomitantly the incidence of obesity has been increasing worldwide. This review summarizes the available studies on minimal invasive surgery in obese women with gynaecological malignancies. We undertook a literature search to identify the differences between traditional open methods and the laparoscopic approach in terms of intra- and postoperative outcome and patient safety. Only eight relevant studies were identified. Six of these focused on endometrial cancer, one study included early stage cervical and ovarian cancers with other benign conditions, while another paper included cervical and endometrial pre-cancers and only a few malignant conditions. Obesity is generally known to increase the risk of intra- and postoperative complications. However, several studies show that obesity, formerly precluding keyhole surgery, seems now to be an indication for the laparoscopic approach. As compared to laparotomy, laparoscopic surgery has a good postoperative outcome, reduced estimated blood loss (EBL) and pain and in some series an increased lymph node count. Laparoscopy has been shown to be cost effective with a shorter hospital stay and return to normal activity. Survival is reported to be the same with both laparotomy and laparoscopy. The benefits of minimal invasive surgery in gynaecological surgery are starting to be found with robotic surgery. PMID:20079589

    Recent research has established a link between disgust sensitivity and stigmatizing reactions to various groups, including obese individuals. However, previous research has overlooked disgust's multiple evolved functions. Here, we investigated whether the link between disgust sensitivity and obesity stigma is specific to pathogen disgust, or whether sexual disgust and moral disgust--two separate functional domains--also relate to negative attitudes toward obese individuals. Additionally, we investigated whether sex differences exist in the manner disgust sensitivity predicts obesity stigma, whether the sexes differ across the subtypes of obesity bias independent of disgust sensitivity, and last, the association between participants' BMI and different subtypes of obesity stigma. In study 1 (N = 92), we established that obesity elicits pathogen, sexual, and moral disgust. In study 2, we investigated the relationship between these types of disgust sensitivity and obesity stigma. Participants (N = 387) reported their level of disgust toward various pathogen, sexual, and moral acts and their attitudes toward obese individuals. For women, but not men, increased pathogen disgust sensitivity predicted more negative attitudes toward obese individuals. Men reported more negative general attitudes toward obese individuals whereas women reported greater fear of becoming obese. The sexes also differed in how their own BMI related to the subtypes of obesity stigma. These findings indicate that pathogen disgust sensitivity plays a role in obesity stigma, specifically for women. Defining the scope of disgust's activation in response to obesity and its relationship with other variables can help identify possible mechanisms for understanding and ultimately alleviating prejudice and discrimination.

    Objective To examine provider adherence to prenatal care (PNC) content in obese and non-obese women and perinatal outcomes in obese women experiencing low and medium versus high adherence to PNC content. Methods Provider adherence to PNC content (low <50%, medium 50–79%, and high ≥80%) was compared between obese (n=69) and non-obese (n=128) women in a linked database of deliveries to low-income, minority women from 2003-2004. Sample content items included procedures delivered at every visit (blood pressure, urinalysis, maternal weight, fetal heart rate check), timed screenings for birth defects and gestational diabetes, prenatal vitamin prescriptions, and depression screening. Weight gain, preterm deliveries, cesareans, and birthweight were compared between obese women with low and medium versus high adherence to PNC content using multivariable logistic regression. Results High provider adherence to an eight-item PNC content score (56.3% vs. 66.5%, p=0.02) and depression screening (2.0% vs. 11.4%, p=0.001) were both lower for obese versus non-obese women. Among obese women, there were no differences by level of provider adherence to PNC content in preterm delivery, cesareans, and low birth weight, but obese women experiencing low and medium versus high adherence were more likely to gain ≥20lbs (aOR 5.5, 95%CI 1.3-23.3). Conclusion Providers may be administering PNC differently to obese and non-obese women. PNC for obese women who are at high risk of adverse perinatal outcomes needs to be addressed especially as it relates to depression screening and gestational weight gain. PMID:23912316

    Obesity is not a single disease, but a variety of conditions resulting from different mechanisms and associated with various types and degrees of risks. To determine who should lose weight, how much weight should be lost, and how to undertake weight loss, the following types of information are needed: personal-demographic data, developmental patterns, family history, energy balance, body composition/fat distribution, psychological/behavioral measures, endocrine/metabolic measures, complications and associated conditions. Weight reduction should be undertaken by women with morbid obesity, with complications secondary to the obesity, with a strong family history of conditions associated with obesity, or with increased abdomen:hip ratios. In contrast, women who have excess weight localized in the hips and thighs and no personal or family history of associated conditions may not benefit from dietary restriction. Low calorie diets result in adaptive changes, "designed" to prolong survival in the face of famine. These include changes in water balance, metabolic rate, and appetite. Metabolic rate declines, allowing the individual to burn fewer and fewer calories. Each time a woman diets she tends to lose weight less rapidly than the time before. "Restrained eating" predisposes binge eating. Indeed, bulimia rarely occurs in the absence of prior caloric restrictions. Current medical definitions of obesity do not consider these nuances. Existing definitions "over-diagnose" obesity in women, in general, and in older women and nonwhite women, in particular. For example, by existing standards, more than 60 percent of black women more than 45 years of age are considered obese. In contrast, the health risks of similar degrees of obesity are substantially greater for men than for women. Part of the problems lies in the fact that many women have pear-shaped fat distribution,a pattern which is not associated with increased health risks.Current cultural definitions of obesity for

    This research examines the influence of messages from religious leaders and congregants on whether Korean women are overweight or obese. Data were drawn from telephone interviews with a probability sample (N=591) of women of Korean descent living in California. Overweight or obese prevalence was measured using World Health Organization standards for Asians (BMI>23). Respondents reported the frequency of messages discouraging “excessive eating” or encouraging “exercise” from religious leaders and congregants during a typical month. When conditioned on leaders’ messages, the frequency of congregants’ messages was associated with a significantly lower probability of being overweight or obese, although messages from either in the absence of the other were unassociated with being overweight or obese. At least for Korean women, religion may help prevent obesity via religious-based social mechanisms. PMID:20886700

    The impact of stress on circulating levels of appetite-regulating hormones remains largely unknown. The aim of this study was to analyze the effect of acute psychosocial stress on the gut hormone peptide YY (PYY) secretion in obese and normal weight women. Therefore, we compared pre- and post-prandial plasma PYY secretion of 42 obese and 43 normal weight women in a repeated measure randomized controlled laboratory experiment. PYY and cortisol concentrations were measured and ratings of stress and satiety were also recorded in response to a psychological stressor (Trier Social Stress Test, TSST). PYY samples were collected in the fasting state both before participating in the TSST and before a control session. Participants had a standardized meal after the TSST and control session, respectively. PYY was measured both 30 and 60 min after the TSST and control session, respectively. Stress inhibited PYY secretion as well as food intake in all women, but did not influence subjective satiety perception. The present data indicate that despite of lower PYY levels the subjects' requirement to overeat was not increased. From an evolutionary perspective this finding is adaptive. After stress the organism is prepared for fight or flight reaction, whereas not primarily necessary functions are inhibited. Therefore, increased food intake during stress would be dysfunctional.

    Obesity is a public health concern worldwide, arising from multifaceted and complex causes that relate to individual choice and lifestyle, and the influences of wider society. In addition to a long-standing focus on both childhood and adult obesity, there has been more recent concern relating to maternal obesity. This review explores the published evidence relating to maternal obesity incidence and associated inequalities, the impact of obesity on maternity services, and associated guidelines. Epidemiological data comprising three national maternal obesity datasets within the UK have identified a significant increase in maternal obesity in recent years, and reflect broad socio-demographic inequalities particularly deprivation, ethnicity and unemployment. Obese pregnancies present increased risk of complications that require more resource intensive antenatal and perinatal care, such as caesarean deliveries, gestational diabetes, haemorrhage, infections and congenital anomalies. Healthcare professionals also face difficulties when managing the care of women in pregnancy as obesity is an emotive and stigmatising topic. There is a lack of good-quality evidence for effective interventions to tackle maternal obesity. Recently published national guidelines for the clinical management and weight management of maternal obesity offer advice for professionals, but acknowledge the limitations of the evidence base. The consequence of these difficulties is an absence of support services available for women. Further evaluative research is thus required to assess the effectiveness of interventions with women before, during and after pregnancy. Qualitative work with women will also be needed to help inform the development of more sensitive risk communication and women-centred services. PMID:21854697

    Obesity is often accompanied by weight stigmatization; subsequently, individuals with obesity frequently face social rejection. It has been shown that recurrent negative social experiences can alter the perception of social cues. However, the way individuals with obesity process social stimuli is not well understood. This study aims to investigate obesity-related alterations in social compared to nonsocial information processing. Women with obesity (n = 14) and without obesity (n = 14) participated in a social and a monetary incentive delay task in which they anticipated and received positive, negative, and neutral outcomes in the form of faces or money. During the experiment, phasic heart rate changes and reaction times were measured. Women with obesity, compared to lean women, exhibited a stronger differentiation during the anticipation of monetary and social reinforcement, showing slower reaction times to social cues compared to monetary cues. During the outcome processing phase, women with obesity relative to controls demonstrated diminished heart rate responses particularly to negative social outcomes. Interestingly, differences in cardiac responses in participants with obesity were moderated by weight-related teasing experiences. In women with obesity, a higher BMI was associated with blunted cardiac responses to social cues relative to monetary cues only if they reported more emotional pain after weight-related teasing. Our results contribute to a better understanding of social information processing in obesity and give first evidence for the role of negative social experiences in reinforcement processing.

    The World Health Organization estimates that nearly 2 billion people worldwide are overweight, 600 million of whom are obese. The increasing prevalence of this condition in women is of particular concern given its impact on reproductive health and mortality. Burgeoning data implicating maternal obesity in fetal programming and the metabolic health of future generations further suggest that obesity in women is one of the most pressing public health concerns of the twenty-first century. However, health care professionals are infrequently engaged in obesity management. This article provides a conceptual understanding of obesity and a rational approach to treatment. PMID:27212089

    Once a low-risk pregnancy has been established, walking in combination with nutritional control may be effective in preventing excessive weight gain in overweight and obese women. Maternal exercise prescription should use the Frequency, Intensity, Time spent and Type of exercise principle, with a frequency of three to four sessions per week as ideal. Intensity based on a target heart-rate zone of 110 to 131 beats per minute for women 20 to 29 years of age and 108 to 127 beats per minute for women 30 to 39 years of age, coupled with use of the rating of perceived exertion scale and the "Talk Test" is suggested. Dieting and exercise together are most effective in reducing weight retention after childbirth and compliance may be improved by incorporating child-care and children into the exercise routine. After medical consultation, postpartum women should begin exercise slowly, starting from 15 minutes, and building to at least 150 minutes of aerobic activity per week, with this activity spread throughout the week.

    Background As a result of the growth of the obese population, the number of obese women of fertile age has increased in the last few years. Obesity in pregnancy is related to greater levels of anxiety, depression and physical harm. However, pregnancy is an opportune moment for the intervention of health care professionals to address obesity. The objective of this study was to describe how obese pregnant women emotionally experience success in adequate weight control. Methods and Findings Using a qualitative design that seeks to understand content in the field of health, the sample of subjects was deliberated, with thirteen obese pregnant women selected to participate in an individual interview. Data was analysed by inductive content analysis and includes complete transcription of the interviews, re-readings using suspended attention, categorization in discussion topics and the qualitative and inductive analysis of the content. The analysis revealed four categories, three of which show the trajectory of body care that obese women experience during pregnancy: 1) The obese pregnant woman starts to think about her body;2) The challenge of the diet for the obese pregnant woman; 3) The relation of the obese pregnant woman with the team of antenatal professionals. The fourth category reveals the origin of the motivation for the change: 4) The potentializing factors for change: the motivation of the obese woman while pregnant. Conclusions During pregnancy, obese women are more in touch with themselves and with their emotional conflicts. Through the transformations of their bodies, women can start a more refined self-care process and experience of the body-mind unit. The fear for their own and their baby's life, due to the risks posed by obesity, appears to be a great potentializing factor for change. The relationship with the professionals of the health care team plays an important role in the motivational support of the obese pregnant woman. PMID:26529600

    Summary Abstract South Africa (SA) is undergoing a rapid epidemiological transition and has the highest prevalence of obesity in sub-Saharan Africa (SSA), with black women being the most affected (obesity prevalence 31.8%). Although genetic factors are important, socio-cultural, environmental and behavioural factors, as well as the influence of socio-economic status, more likely explain the high prevalence of obesity in black SA women. This review examines these determinants in black SA women, and compares them to their white counterparts, black SA men, and where appropriate, to women from SSA. Specifically this review focuses on environmental factors influencing obesity, the influence of urbanisation, as well as the interaction with socio-cultural and socio-economic factors. In addition, the role of maternal and early life factors and cultural aspects relating to body image are discussed. This information can be used to guide public health interventions aimed at reducing obesity in black SA women. PMID:24051701

    Background African American women have the highest rates of obesity in the United States. The prevalence of obesity in this group calls for the identification of psychosocial factors that increase risk. Psychological stress has been associated with obesity in women; however, there is scant literature that has explored the impact of racism on body mass index (BMI) in African American women. Objective The current study aimed to determine whether emotional responses and behavioral coping responses to perceived racism were associated with BMI in African American women. Methods A sample of 110 African American women participated in a community-based study. Height and weight measurements were taken to calculate BMI and participants completed the Perceived Racism Scale and the Perceived Stress Scale. Results Hierarchical regression analyses demonstrated a significant relationship between BMI and behavioral coping responses to perceived racism. Findings for emotional responses to perceived racism and appraisal of one's daily life as stressful were nonsignificant. Mean comparisons of BMI groups showed that obese African American women used more behavioral coping responses to perceived racism as compared to normal-weight and overweight women in the sample. Conclusion Findings suggest that behavioral coping responses better explained increased risk for obesity in African American women. A biobehavioral pathway may explain this finding with a stress-response process that includes cortisol reactivity. Maladaptive behavioral coping responses may also provide insight into obesity risk. Future research is needed to determine which behavioral coping responses place African American women at greater risk for obesity. PMID:21999035

    OBJECTIVES. Although differences in obesity between Blacks and Whites are well documented in adult women, less information is available on potential correlates of these differences, especially in young adults. METHODS. The association between behavioral and demographic factors and body size was assessed in 2801 Black and White women aged 18 to 30 years. RESULTS. Black women had significantly higher age-adjusted mean body mass index and subscapular skinfold thickness than did White women. Obesity had different associations with age and education across racial groups. A positive relationship between age and obesity was seen in Black women but not in White women, whereas a negative association between education and body size was noted only in White women. Potential contributing factors to the increased prevalence of obesity in Black women include a more sedentary lifestyle, higher energy intake, earlier menarche, and earlier age at first childbirth. CONCLUSIONS. The difference in obesity across race could not be explained completely by these factors, since within virtually all strata, Black women had higher body mass indexes. Further investigation is needed to develop interventional strategies to prevent or reduce excess levels of obesity in Black women. PMID:1456336

    Pre-pregnancy overweight and obesity is associated with poor health outcomes for the mother and the child. General population studies suggest that childhood maltreatment is associated with obesity in adulthood. The aim of our study was to examine the association between pre-pregnancy overweight and obesity and a history of childhood abuse or neglect including different stages of severity of abuse and neglect. Three hundred twenty-six normal weight, overweight, or obese pregnant women reported demographic data, height and weight, and general psychological distress at 18-22 weeks of gestation. Childhood maltreatment was assessed using the Childhood Trauma Questionnaire. Associations were examined using logistic regression analyses and a reference group of normal weight women. Fifty percent reported a history of abuse or neglect. After adjusting for age, education, income, marital status, and the number of previous children, pre-pregnancy overweight and obesity were strongly associated with severe physical abuse (overweight: OR = 8.33, 95% CI 1.48-47.03; obesity: OR = 6.31, 95% CI 1.06-37.60). Women with severe physical neglect (OR = 4.25, 95% CI 1.23-14.74) were at increased risk of pregnancy overweight. We found a dose-response relationship between physical abuse and pre-pregnancy overweight and obesity. Whereas other studies report an association between childhood maltreatment and pre-pregnancy obesity, this is the first study that found an association between childhood maltreatment and pre-pregnancy overweight. Considering the severe health risks of pre-pregnancy overweight and obesity and the long-term consequences of childhood maltreatment, affected women constitute a subgroup with special needs in prenatal care. Further research is needed to improve the understanding of the underlying mechanisms. PMID:26386682

Second, the association between obesity and cardiometabolic risk factors in the combined group of Nenets and Russian women. Third, ethnic differences in the association between obesity and cardiometabolic risk factors. Design Cross-sectional study performed in 2008–2009. Subjects: 93 Nenets women, aged 19–77 (the indigenous village, the Nenets Autonomous Area) and 132 Russian women, aged 21–72 (Arkhangelsk city). Obesity was defined as body mass index (BMI)≥30 kg/m2, waist circumference (WC)≥88 cm and or waist-to-hip ratio (WHR)≥0.85%. We assessed associations between obesity and cardiometabolic risk factors by linear and logistic regression models that included covariates of ethnicity, age, smoking and physical activity. We also tested for interaction between obesity measurements and ethnicity. Results Prevalence of obesity estimated through BMI, WC and WHR were 42.5, 45.3 and 41.9% in Nenets and 34.4, 46.4 and 29.5% in Russians, respectively, with no differences found. BMI, WC and WHR associated positively with triglycerides, fasting insulin and Homeostasis Model Assessment of Insulin Resistance index. In addition, BMI and WC correlated negatively with high-density lipoprotein cholesterol and positively with systolic blood pressure and apolipoprotein B/apoliporotein A–I ratio. WC explained significant variation in fasting glucose (FG) level. BMI predicted type 2 diabetes history. FG level associated strongly with ethnicity and was found to be higher in Russians. Conclusions We found no differences in prevalence of obesity between Nenets and Russian females. Obesity was associated with cardiometabolic risk factors independently of ethnicity in the

    The aim of the present study was to assess female sexual function in an obese group (250 women) and to compare it with a control group (100 women), among 25-35-year-old uncircumcised Egyptian women, using female sexual function index (FSFI) score. FSFI total score of ⩽ 26.55 was considered diagnostic of Female Sexual Dysfunction (FSD). The percentage of FSD in the obese group was 73.6% while it was 71% in the control group, which was statistically insignificant (P > 0.05). The difference between both groups regarding the total (FSFI) score was insignificant (P > 0.05), but arousal and satisfaction domains scores were significantly lower in the obese group. In the obese group, a strong negative correlation between body mass index and arousal, orgasm and the total FSFI score was found. Women with excessive obesity had the lowest total FSFI score. In the obese group, college graduates had the highest total scores and all domain scores of FSFI followed by high school graduates while the least educated women had the lowest scores and when these subgroups were compared, significant differences were found among them. We conclude that in uncircumcised 25-35-year-old Egyptian women, obesity is not a major detrimental factor for FSD, but it may affect some sexual domains such as arousal and satisfaction, although excessive obesity is associated with FSD. Also, educational and cultural factors may have an impact on perception of sex and pleasure. PMID:26155831

    This study was designed to obtain baseline data regarding self-reported body image, attitudes toward overweight people, and dietary behaviors of normal-weight and obese women in Taiwan. Fifty obese women (BMI >= 27) and age-matched normal-weight women participated in this study. Written questionnaires were used for data collection. Simple frequency and t-test were used to analyze data. In general, the majority of normal-weight women perceived themselves as being heavier than their actual body weight. The normal-weight group had more high inaccurate images of their bodies than that of the obese group (72% vs. 24%). Obese and normal-weight women had similar attitudes to overweight people, but some of their attitudes showed significant differences. Obese women would prefer to consume more fried foods and drink sugar-containing foods than would normal-weight women (p < 0.05). Education about accurate perceptions of what is normal weight for women and adopting energy-diluted foods for obese women is needed in the future. PMID:17704039

    We examined the hypothesis that postmenopausal women with the beta3-adrenoceptor gene variant (Trp64Arg) have reduced total daily energy expenditure (TEE), altered free fatty acid kinetics, and increased intra-abdominal fat. A secondary objective was to examine whether the obese state masks the effect of the variant on resting metabolic rate (RMR). There were 23 obese heterozygous women with the genetic variant (age 58 +/- 6 years; BMI 36 +/- 7 kg/m2) who were compared with 19 homozygous obese women with the normal allele (age 56 +/- 4 years; BMI 36 +/- 3 kg/m2). Daily energy expenditure was determined from doubly labeled water and indirect calorimetry, lipolysis from infusion of [1-13C]palmitate, and body fat distribution from computed tomography. No significant differences were found in TEE, RMR, energy expenditure of physical activity, the thermic effect of a meal, fat oxidation as estimated by fasting and postprandial respiratory quotients (RQs), or rate of lipolysis. Similarly, no difference was found in visceral adipose tissue and abdominal subcutaneous fat areas. When RMR was compared between obese (n = 23) and never-obese women with the Trp64Arg variant (n = 16), we found a 317 kcal/day lower RMR in never-obese women after controlling for fat mass, fat-free mass, and age (P < 0.0017). These results do not support the hypothesis that already obese women with the Trp64Arg polymorphism of the beta3-adrenergic receptor gene have lower daily energy expenditure, altered lipolysis, and increased abdominal obesity. On the other hand, the lower RMR in never-obese women suggests that the obese state may mask a moderate effect of the Trp64Arg variant on energy expenditure. Although these results need to be confirmed in other populations, the obese state may have been a confounding factor in previous studies of the beta3-adrenoceptor Trp64Arg variant and energy expenditure.

    Objective To determine the prevalence of obesity and evaluate how accurately standard anthropometric measures identify obesity among women with SLE. Methods Dual-energy x-ray absorptiometry (DEXA), height, weight, and waist and hip circumference were collected from 145 women with SLE. Three anthropometric proxies of obesity (body mass index (BMI) ≥30 kg/m2, waist circumference (WC) ≥88 cm, and waist-hip ratio (WHR) ≥0.85) were compared to a DEXA-based obesity criterion. Correspondence between measures was assessed with Cohen’s kappa. Receiver operating characteristic (ROC) curves determined optimal cut-points for each anthropometric measure, relative to DEXA. Framingham cardiovascular risk scores were compared among women who were classified as not obese by both traditional and revised anthropometric definitions, obese by both definitions, and obese only by the revised definition. Results 28%, 29%, 41%, and 50% were classified as obese by WC, BMI, WHR, and DEXA, respectively. Correspondence between anthropometric and DEXA-based measures was moderate. Women misclassified by anthropometric measures had less truncal fat and more appendicular lean and fat mass. Cut-points were identified for anthropometric measures to better approximate DEXA estimates of percent body fat: BMI ≥26.8 kg/m2, waist circumference ≥84.75 cm., and waist-hip ratio ≥0.80. Framingham risk scores were significantly higher in women classified as obese by either traditional or revised criteria. Conclusions A large percentage of this group of women with SLE was obese. Substantial portions of women were misclassified by anthropometric measures. Utility of revised cut-points compared to traditional cut-points in identifying risk of cardiovascular disease or disability remains to be examined in prospective studies, but results from the Framingham risk score analysis suggest that traditional cut-points exclude a significant number of at-risk women with SLE.

    Hypertension is highly prevalent in South Africa, resulting in high stroke mortality rates. Since obesity is very common among South African women, it is likely that obesity contributes to the hypertension prevalence. The aims were to determine whether black African women have higher blood pressures (BPs) than Caucasian women, and whether obesity is related to their cardiovascular risk. African (N=102) and Caucasian (N=115) women, matched for age and body mass index, were included. Correlations between obesity (total body fat, abdominal obesity and peripheral fat) and cardiovascular risk markers (haemodynamic parameters, lipids, inflammatory markers, prothrombotic factors, adipokines, HOMA-IR (homoeostasis model assessment insulin resistance)) were compared between the ethnic groups (adjusted for age, smoking, alcohol and physical activity). Comparisons between low- and high-BP groups were also made for each ethnic group. Results showed that African women had higher BP (P<0.01) with increased peripheral vascular resistance. Surprisingly, African women showed significantly weaker correlations between obesity measures and cardiovascular risk markers when compared to Caucasian women (specifically systolic BP, arterial resistance, cardiac output, fibrinogen, plasminogen activator inhibitor-1, leptin and resistin). Interestingly, the latter risk markers were also not significantly different between low- and high-BP African groups. African women, however, presented significant correlations of obesity with triglycerides, C-reactive protein and HOMA that were comparable to the Caucasian women. Although urban African women have higher BP than Caucasians, their obesity levels are weakly related to traditional cardiovascular risk factors compared to Caucasian women. The results, however, suggest a link with the development of insulin resistance. PMID:18432254

    Historical data from 26 638 20-to 40-year women were used to study the association between obesity and menstrual abnormalities including evidence of infertility. It was found that women with evidence of anovulatory cycles, ie, irregular cycles greater than 36 days, and hirsutism, were more than 30 lb (13.6 kg) heavier than women with no menstrual abnormalities after adjusting for height and age. The percentage of women with evidence of anovulatory cycles was 2.6 per cent for women less than 20 per cent overweight, 4.0 per cent for women 20-49 per cent overweight, 5.8 per cent for women 50-74 per cent overweight., and 8.4 per cent for women more than 74 per cent overweight Women with a single menstrual abnormality including cycles greater than 36 days, irregular cycles, virile hair growth with facial hair, or heavy flow were also significantly heavier than women with normal values for these factors. A longer duration of obesity was associated with facial hair. Another analysis found that teenage obesity was greater for never-pregnant married women than for previously pregnant married women and for women having ovarian surgery for polycystic ovaries than for women having ovarian surgery for other reasons. This also supports an association of obesity with anovulatory cycles. These findings showing evidence of abnormal ovulation, menstrual abnormalities and excess hair growth in obese women may be explained by the recent studies of others demonstrating an association between obesity and hormonal imbalances.

    The purpose of this study was to compare different methods to identify metabolically healthy but obese (MHO) individuals in a cohort of obese postmenopausal women. We examined the anthropometric and metabolic characteristics of 113 obese (age: 57.3 +/- 4.8 years; BMI: 34.2 +/- 2.7 kg/m(2)), sedentary postmenopausal women. The following methods were used to identify MHO subjects: the hyperinsulinemic-euglycemic clamp (MHO: upper quartile of glucose disposal rates); the Matsuda index (MHO: upper quartile of the Matsuda index); the homeostasis model assessment (HOMA) index (MHO: lower quartile of the HOMA index); having 0-1 cardiometabolic abnormalities (systolic/diastolic blood pressure > or =130/85 mm Hg, triglycerides (TG) > or =1.7 mmol/l, glucose > or =5.6 mmol/l, HOMA >5.13, high-sensitive C-reactive protein (hsCRP) >0.1 mg/l, high-density lipoprotein-cholesterol (HDL-C) <1.3 mmol/l); and meeting four out of five metabolic factors (HOMA < or =2.7, TG < or =1.7 mmol/l, HDL-C > or =1.3 mmol/l, low-density lipoprotein-cholesterol < or =2.6 mmol/l, hsCRP < or =3.0 mg/l). Thereafter, we measured insulin sensitivity, body composition (dual-energy X-ray absorptiometry), body fat distribution (computed tomography scan), energy expenditure, plasma lipids, inflammation markers, resting blood pressure, and cardiorespiratory fitness. We found significant differences in body composition (i.e., peripheral fat mass, central lean body mass (LBM)) and metabolic risk factors (i.e., HDL-C, hsCRP) between MHO and at risk individuals using the different methods to identify both groups. In addition, significant differences between MHO subjects using the different methods to identify MHO individuals were observed such as age, TG/HDL, hsCRP, and fasting insulin. However, independently of the methods used, we noted some recurrent characteristics that identify MHO subjects such as TG, apolipoprotein B, and ferritin. In conclusion, the present study shows variations in body composition

    Despite the increase in obesity among women of reproductive ages, few studies have considered maternal obesity as a risk factor for breast-feeding success. We tested the hypothesis that women who are obese (BMI = 30-34.9) and very obese (BMI >or=35) before pregnancy are less likely to initiate and maintain breast-feeding than are their normal-weight counterparts (BMI = 18.5-24.9) among white and black women. Data from 2000 to 2005 South Carolina Pregnancy Risk Assessment Monitoring System (PRAMS) were used. The overall response rate was 71.0%; there were 3,517 white and 2,846 black respondents. Black women were less likely to initiate breast-feeding and breast-fed their babies for a shorter duration than white women. Compared to normal-weight white women, very obese white women were less likely to initiate breast-feeding (odds ratio: 0.63; 95% confidence interval (CI) = 0.42, 0.94) and more likely to discontinue breast-feeding within the first 6 months (hazard ratio (HR) = 1.89; 95% CI: 1.39, 2.58). Among black women, prepregnancy BMI was neither associated with breast-feeding initiation nor with breast-feeding continuation within the first 6 months. Because very obese white women are less likely to initiate or continue breast-feeding than other white women, health professionals should be aware that very obese white women need additional breast-feeding support. Lower rates of breast-feeding among black women suggest that they should continue to be the focus of the programs and policies aimed at breast-feeding promotion in the United States. PMID:19521347

    We examined whether a history of self-reported childhood sexual abuse (CSA) moderates the relationship between obesity and mental health symptoms (depression, anxiety, and posttraumatic stress disorder) in an ethnically diverse sample of low-income women. A community sample of 186 women completed self-report measures and had their weight and height measured. Body mass index and CSA had an interactive effect on all mental health measures, such that obese women with a CSA history reported substantially higher levels of all symptoms. These results give greater specificity to the obesity-mental health link reported in previous studies and provide possible directions for targeted intervention. PMID:26541476

    Garcinia cambogia seems to promote weight reduction and improvement on lipid profile by its major compound, hydroxycitric acid (HCA), blocking ATP-citratelyase, potentially inhibiting lipogenesis. Furthermore, it is suggested that its extract is able to change the adipokine levels. Thus, the aim of this study was to analyse the effect of G. cambogia on the lipid profile, endocrine, calorimetric and anthropometric parameters of obese women. The women (BMI > 25 kg/m(2) ; age 25-60 years), divided in treated (n = 30) and control (n = 13) groups, received 2.4 g (800 mg 3×/day) of garcinia extract (50% of HCA) or placebo during 60 days, respectively, as well as dietary control. Weight, BMI, waist-hip ratio and percentage of fat mass, resting metabolic rate, respiratory coefficient, triglycerides (TG), total cholesterol, HDL and LDL, leptin and insulin serum levels were evaluated. TG was significantly reduced in the treated group (p = 0.0002) and the post-treatment variation was different compared to the placebo group (p = 0.04). No significant response was observed on other variables of the lipid profile, or on the anthropometric and calorimetric parameters. Leptin and insulin levels did not change significantly after the treatment. The short-term treatment with G. cambogia demonstrated a hypotriglyceridemic effect, which does not appear to be related to changes in leptinemia. PMID:24133059

    The object of this study was to assess the obesity in postmenopausal women, according to age at childbirth.We analyzed the association between age at first childbirth, age at last childbirth, parity, and subject obesity status (general obesity; BMI >25 kg/m, nongeneral obesity; BMI ≤25 kg/m, abdominal obesity; waist circumference >85 cm, nonabdominal obesity; waist circumference ≤85 cm), using data from a nationwide population-based survey, the 2010 to 2012 Korean National Health and Nutrition Examination Survey. Data from a total of 4382 postmenopausal women were analyzed using multivariate regression analysis with complex survey design sampling. And, the subjects were subdivided into groups according to obesity or not. Age, smoking, alcohol consumption, exercise, education, income level, number of pregnancies, oral contraceptive uses, breast feeding experience were adjusted as the confounders.The prevalence of general obesity among Korean postmenopausal women was 37.08%. Women with general obesity and abdominal obesity were significantly younger at first childbirth compared with women with nongeneral obesity and no abdominal obesity (23.89 ± 0.1 vs. 23.22 ± 0.1, P <0.001). Age at first childbirth was inversely associated with obesity, while age at last childbirth was not associated with obesity or abdominal obesity. Women with a higher number of pregnancies were also more likely to have obesity and abdominal obesity. Age at first childbirth remained significantly associated with obesity, after adjusting for confounding factors.Obesity in postmenopausal women is associated with first childbirth at a young age, and higher parity. Further research is needed to clarify the association between obesity and reproductive characteristics. PMID:27175656

    Abstract Background It is generally accepted that obesity and depression are positively related in women. Very little prior research, however, has examined potential variation in this relationship across different racial/ethnic groups. This paper examines the association between obesity and depression in non-Hispanic White, non-Hispanic Black, and Mexican American women. Methods The sample included women aged 20 years and older in the 2005–2008 National Health and Nutrition Examination Surveys (n=3666). Logistic regression was used to assess the relationship between obesity and depression syndrome (assessed using the Patient Health Questionnaire-9), after adjusting for covariates. We then investigated whether this association varied by race/ethnicity. Results Overall, obese women showed a 73% greater odds of depression (odds ratio [OR]=1.73; 95% confidence interval [CI]=1.19, 2.53) compared with normal weight women. This association varied significantly, however, by race/ethnicity. The obesity-depression associations for both Black and Mexican American women were different from the positive association found for White women (ORBlack*obese=0.24; 95% CI=0.10,0.54; ORMexican American*obese=0.42; 95% CI=1.04). Among White women, obesity was associated with significantly greater likelihood of depression (OR=2.37; 95% CI=1.41, 4.00) compared to normal weight. Among Black women, although not statistically significant, results are suggestive that obesity was inversely associated with depression (OR=0.56; 95% CI=0.28, 1.12) relative to normal weight. Among Mexican American women, obesity was not associated with depression (OR=1.01; 95% CI=0.59, 1.72). Conclusions The results reveal that the association between obesity and depression varies by racial/ethnic categorization. White, but not Black or Mexican American women showed a positive association. Next research steps could include examination of factors that vary by race/ethnicity that may link obesity to depression

    Using data of the third round of the National Family Health Survey (NFHS) 2005-2006, this study examined the prevalence of overweight and obesity among women from different economic strata in urban India. The study used a separate wealth index for urban India constructed using principal components analysis (PCA). The result shows that prevalence of overweight and obesity is very high in urban areas, more noticeably among the non-poor households. Furthermore, overweight and obesity increase with age, education, and parity of women. The results of multinomial logistic regression show that non-poor women are about 2 and 3 times more at risk of being overweight and obese respectively. Marital status and media exposure are the other covariates associated positively with overweight and obesity. Thus, the growing demand which now appears before the Government or urban health planners is to address this rising urban epidemic with equal importance as given to other issues in the past.

    Studies of social determinants of weight and health in the US have typically relied on self-reported education and incomes as the two primary measures of socioeconomic status (SES). The assessed value of one's home, an important component of wealth, may be a better measure of the underlying SES construct and a better predictor of obesity. The Seattle Obesity Study (SOS), conducted in 2008-9, was a cross-sectional random digit dial telephone survey of 2001 adults in King County, Washington State, US. Participants' addresses were geocoded and residential property values for each tax parcel were obtained from the county tax assessor's database. Prevalence ratios of obesity by property values, education, and household income were estimated separately for women and men, after adjusting for age, race/ethnicity, household size, employment status and home ownership. Among women, the inverse association between property values and obesity was very strong and independent of other SES factors. Women in the bottom quartile of property values were 3.4 times more likely to be obese than women in the top quartile. No association between property values and obesity was observed for men. The present data strengthen the evidence for a social gradient in obesity among women. Property values may represent a novel and objective measure of SES at the individual level in the US. Measures based on tax assessment data will provide a valuable resource for future health studies. PMID:22591823

    Objective To describe the effects of obesity on the pharmacokinetics and dosing of chemotherapies and provide recommendations for chemotherapy management in obese women with gynecologic malignancies. Methods PubMEd and MEDLINE databases were searched for articles published before June 2014. Only English-language articles were considered. 84 manuscripts were reviewed and 66 were included. Search terms included: obesity, overweight, body mass index, body surface area, glomerular filtration rate, chemotherapy, ovarian cancer, endometrial cancer, inflammation, and pharmacokinetics, Results Obese cancer patients have worse clinical outcomes, compared with non-obese patients. This may be because of differences in pharmacokinetics, metabolic dysregulation, or physicians' decisions to reduce chemotherapy dose-intensity during treatment to minimize toxicities. A 2012 American Society of Clinical Oncology Clinical Practice Guideline recommends using actual body weight for chemotherapy dosing in all patients treated with curative intent, irrespective of obesity, to avoid compromising clinical outcomes, including progression free survival (PFS) and overall survival (OS). In women with gynecologic cancers most studies demonstrate no difference in PFS or OS when obese patients receive the same chemotherapy dose intensity as non-obese patients, except perhaps with bevacizumab. Conclusions Chemotherapy dose-intensity is a critical determinant of cancer outcomes and should be maintained in all patients, irrespective of obesity. Future studies should prospectively examine the impact of obesity on clinical outcomes (adverse events, survival) to improve the care of this growing population of patients who are at risk for inferior clinical outcomes.

    Despite intensive focus and interventions at societal and individual levels, more than a third of people in the United States are overweight or obese, and childhood/adolescent obesity rates have dramatically increased during the past three decades. Biomedical research has shown a clear link between the prenatal environment and lifetime adiposity. Children born to overweight and obese women with impaired glucose metabolism show cardiometabolic consequences throughout their life spans that, in turn, affect their children's adiposity. Awareness of this intergenerational cycle of obesity can prompt nurses to intervene in the preconception, prenatal, and postnatal phases. PMID:27287355

Objectives: To find the prevalence and risk factors for obesity in women aged 20-60 years in Ludhiana city. Methods: The present study is a community based cross sectional study carried out in an urban area of Ludhiana among women aged 20-60 years. Among the study population of 324 women, a pre-designed and pre-tested questionnaire was used to record the socio-demographic and anthropometric profile of women. Chi square test and logistic regression was used to find the association of obesity and hypertension with socio-demographic variables. Results: The prevalence of overweight and obesity was 12.7% and 29.6% respectively. Obesity was found to be more common among middle-aged Punjabi housewives belonging to upper socio-economic strata. There was strong association between overweight/obesity and hypertension. PMID:27051092

    PURPOSE: To explore attitudes and perceptions of obesity, and identify preferences for weight-management interventions by African-American and Caucasian women who were followed in general internal medicine clinics. PROCEDURE: Surveys exploring these issues were mailed to African-American (n=240) and Caucasian (n=240) women with a BMI of > or =30. MAIN FINDINGS: Caucasian women felt past weight-loss efforts were helped by weight-loss programs significantly more than African-American women (P<0.001); African-American women were more likely to feel that their cultural background contributed to their weight gain than did Caucasian women (P=0.001). African-American women expressed a higher need for one-on-one counseling with their physician (P<0.001) as well as group meetings with the dietician, physician and other women (P=0.004) than did Caucasian women. African-American women also felt it was more important for weight-loss programs to have information on food common to their culture than did Caucasian women (P<0.001). CONCLUSIONS: Differences in cultural background and preferences about weight loss interventions have important policy implications for how the U.S. healthcare system provides care to an ever-increasing multicultural population with a national epidemic such as obesity.

    The obesity epidemic is of some concern in women of reproductive age. Maternal obesity is associated with many pregnancy complications, especially gestational diabetes and hypertensive disorders of pregnancy. Delivery in obese women is characterized by a high caesarean-section rate and an increased risk of anaesthetic and postoperative complications. Weight retention after birth may increase the risk of type 2 diabetes in the long term. Foetal risks include macrosomia, malformations and increased perinatal mortality, with the long-term infant health marked by a higher risk of obesity and metabolic disorders. Optimal management includes preconception counselling, pregravid weight-loss programmes, monitoring of gestational weight gain, repeated screening for pregnancy complications and long-term follow-up to minimize the social and economic consequences of pregnancy in overweight women.

    The literature has found that eating disorders (ED) patients usually have a depression and anxiety diagnosis. However, not many investigations have studied the relationship between ED and well-being. One of the main problems of patients with ED is their body image. These individuals usually see themselves too big but there are not many investigations that focus on how these patients see people with real weight problems. For this reason in this study it is analyzed how women in risk to develop ED see obese people. 456 female students were selected. It was found that women with high scores in the different subscales of the Eating Attitudes Test 26 (EAT-26; dieting, bulimia and oral control) had lower well-being (both subjective and psychological) and worse attitudes toward obese people (measured with Antifat Attitudes Test, AFA, Beliefs About Obese People Scale, BAOP, and Attitudes Toward Obese People Scale, ATOP) compared with women with low scores in the EAT-26.

    Background: Polycystic ovarian syndrome (PCOS) is one of the most common endocrine diseases of women. Oxidative stress is an important component of the cardio-metabolic risk seen in these women. Oxidative stress has been reported in obese PCOS women. This study is taken up to study oxidative stress in non-obese PCOS women. Materials and Methods: Twenty five non-obese women with PCOS attending the Endocrinology outpatient Department of Sri Venkateswara Institute of Medical Sciences, Tirupati, India along with 25 healthy BMI matched controls were included in the study. The changes in the lipid peroxidation products (MDA), and total anti oxidant capacity (FRAP) as an index of anti oxidant status along with fasting glucose, insulin and uric acid levels were measured in both groups. Insulin resistance was evaluated by using homeostasis model assessment for insulin resistance [HOMA-IR)= [FPG (mg/dl) × insulin (mIU/L)]/ 405] in both groups. Results: Serum MDA and uric acid levels were increased in the study group compared with controls and FRAP levels were decreased in the study group compared to controls though statistically insignificant. Conclusion: Oxidative stress is also present in non-obese women with PCOS. Oxidative stress further increases the CVD risk in these women.Correcting oxidative stress with antioxidants along with monitoring the antioxidant status using a simple assay like FRAP could have a beneficial effect on oxidative stress induced insulin resistance and hyperandrogenism seen in these women.

    Summary A rapid increase in obesity rates worldwide further underscores the importance of better understanding the pharmacokinetic alterations in this sub-population and the subsequent effects on pharmaco-therapeutics. Pharmacokinetics of contraceptive steroids are altered in obese oral contraceptive users which may in turn impact efficacy. Our work has identified several dosing strategies that offset these pharmacokinetic changes and may improve effectiveness for obese OC users. PMID:25354219

    Background: Metabolically healthy obesity may confer lower risk of adverse health outcomes compared with abnormal obesity. Diet and race are postulated to influence the phenotype, but their roles and their interrelations on healthy obesity are unclear. Objective: We evaluated food intakes of metabolically healthy obese women in comparison to intakes of their metabolically healthy normal-weight and metabolically abnormal obese counterparts. Methods: This was a cross-sectional study in 6964 women of the REasons for Geographic And Racial Differences in Stroke (REGARDS) study. Participants were aged 45–98 y with a body mass index (BMI; kg/m2) ≥18.5 and free of cardiovascular diseases, diabetes, and cancer. Food intake was collected by using a food-frequency questionnaire. BMI phenotypes were defined by using metabolic syndrome (MetS) and homeostasis model assessment of insulin resistance (HOMA-IR) criteria. Mean differences in food intakes among BMI phenotypes were compared by using ANCOVA. Results: Approximately one-half of obese women (white: 45%; black: 55%) as defined by MetS criteria and approximately one-quarter of obese women (white: 28%; black: 24%) defined on the basis of HOMA-IR values were metabolically healthy. In age-adjusted analyses, healthy obesity and normal weight as defined by both criteria were associated with lower intakes of sugar-sweetened beverages compared with abnormal obesity among both white and black women (P < 0.05). HOMA-IR–defined healthy obesity and normal weight were also associated with higher fruit and low-fat dairy intakes compared with abnormal obesity in white women (P < 0.05). Results were attenuated and became nonsignificant in multivariable-adjusted models that additionally adjusted for BMI, marital status, residential region, education, annual income, alcohol intake, multivitamin use, cigarette smoking status, physical activity, television viewing, high-sensitivity C-reactive protein, menopausal status, hormone therapy

    This article focuses on the exploration and description of perceptions of patients and community nurses of the phenomenon of obesity as well as any potential problems that could be foreseen if health promotion programs were planned for obese people. Whilst the researcher sought to explore patients' perceptions of obesity as a threat to health it was also necessary to obtain similar information from the community nurses who were giving health services to these patients'. The level of knowledge of obesity as a health problem as well as the nurses personal attitude towards the phenomenon of obesity is crucial in the manner and quality of her interventions. A qualitative, exploratory, descriptive and contextual research design was utilised. Semi-structured interviews were conducted amongst patients and community nurses to collect data regarding perceptions of obesity. Data obtained from patients can be used meaningfully for the planning of health promotion programmes for the obese individuals and families. Some negative and ambivalent statements were also identified as problem areas that need to be worked on. Conclusions drawn from the findings on nurses responses highlighted a number of problem areas which were identified in the cognitive, psychomotor and affective domains of the community nurse as health professional. Certain shortcomings were also identified with the community health structures which may not be supportive to the community nurse, individuals and families with problems of obesity. PMID:11040619

    Success of cricothyroidotomy depends on accurate identification of anatomical neck landmarks. Anaesthetists palpated the cricothyroid membrane of 28 obese and 28 non-obese women in labour (cut-off BMI 30 kg.m(-2) ) and marked the entry point for device insertion with an ultraviolet invisible pen. Ultrasonography was used to mark the midpoint of the cricothyroid membrane and the distance between the two marks was measured. The median (IQR [range]) distance between the two marks was significantly greater in the obese than the non-obese patients (5 (2-9.5 [0-34]) mm vs 1.8 (0.1-6 [0-15]) mm, respectively; p = 0.02). The cricothyroid membrane was accurately identified with digital palpation in only 39% (11/28) of obese compared with 71% (20/28) of non-obese patients (p = 0.03). Increased neck circumference in obese patients was significantly associated with inaccuracy in locating the cricothyroid membrane. Percutaneous identification of the cricothyroid membrane in obese women in labour was poor. Pre-procedural ultrasound may help improved the identification of neck landmarks for cricothyroidotomy.

    Introduction The prevalence of obesity in developing countries especially among women is on the rise. This matter should be taken seriously because it can burden the health care systems and lower the quality of life. Aim The purpose of this study was to determine the prevalence of obesity among adult women in Selangor and to determine factors associated with obesity among these women. Methods This community based cross sectional study was conducted in Selangor in January 2004. Multi stage stratified proportionate to size sampling method was used. Women aged 20–59 years old were included in this study. Data was collected using a questionnaire-guided interview method. The questionnaire consisted of questions on socio-demographic (age, ethnicity, religion, education level, occupation, monthly income, marital status), Obstetric & Gynaecology history, body mass index (BMI), and the Patient Health Questionnaire (PHQ-9). Results Out of 1032 women, 972 agreed to participate in this study, giving a response rate of 94.2%. The mean age was 37.91 ± 10.91. The prevalence of obesity among the respondents was 16.7% (mean = 1.83 ± 0.373). Obesity was found to be significantly associated with age (p = 0.013), ethnicity (p = 0.001), religion (p = 0.002), schooling (p = 0.020), educational level (p = 0.016), marital status (p = 0.001) and the history of suffering a miscarriage within the past 6 months (p = 0.023). Conclusion The prevalence of obesity among adult women in this study was high. This problem needs to be emphasized as the prevalence of obesity keeps increasing, and will continue to worsen unless appropriate preventive measures are taken. PMID:19358728

    Overweight and obese women are at a higher risk for gestational diabetes mellitus. The gut microbiome could modulate metabolic health and may affect insulin resistance and lipid metabolism. The aim of this study was to reveal relationships between gut microbiome composition and circulating metabolic hormones in overweight and obese pregnant women at 16 weeks' gestation. Fecal microbiota profiles from overweight (n = 29) and obese (n = 41) pregnant women were assessed by 16S rRNA sequencing. Fasting metabolic hormone (insulin, C-peptide, glucagon, incretin, and adipokine) concentrations were measured using multiplex ELISA. Metabolic hormone levels as well as microbiome profiles differed between overweight and obese women. Furthermore, changes in some metabolic hormone levels were correlated with alterations in the relative abundance of specific microbes. Adipokine levels were strongly correlated with Ruminococcaceae and Lachnospiraceae, which are dominant families in energy metabolism. Insulin was positively correlated with the genus Collinsella. Gastrointestinal polypeptide was positively correlated with the genus Coprococcus but negatively with family Ruminococcaceae This study shows novel relationships between gut microbiome composition and the metabolic hormonal environment in overweight and obese pregnant women at 16 weeks' gestation. These results suggest that manipulation of the gut microbiome composition may influence pregnancy metabolism. PMID:27217482

    Introduction. Menarche is a critical time point in a woman's reproductive system development; exposures at menarche may influence maternal health. Living in a poorer neighborhood is associated with adult obesity; however, little is known if neighborhood factors at menarche are associated with prepregnancy obesity. Methods. We examined the association of neighborhood-level poverty at menarche with prepregnancy body mass index category in 144 pregnant African-American women. Address at menarche was geocoded to census tract (closest to year of menarche); neighborhood-level poverty was defined as the proportion of residents living under the federal poverty level. Cumulative logistic regression was used to examine the association of neighborhood-level poverty at menarche, in quartiles, with categorical prepregnancy BMI. Results. Before pregnancy, 59 (41%) women were obese. Compared to women in the lowest neighborhood-level poverty quartile, women in the highest quartile had 2.9 [1.2, 6.9] times higher odds of prepregnancy obesity; this was slightly attenuated after adjusting for age, marital status, education, and parity (odds ratio: 2.3 [0.9, 6.3]). Conclusions. Living in a higher poverty neighborhood at menarche is associated with prepregnancy obesity in African-American women. Future studies are needed to better understand the role of exposures in menarche on health in pregnancy. PMID:27418977

    What is the central question of this study? In obesity, the exaggerated blood pressure response to voluntary exercise is linked to hypertension, yet the mechanisms are not fully elucidated. We examined whether involuntary contractions elicit greater haemodynamic responses and altered neural control of blood pressure in normotensive obese versus lean women. What is the main finding and its importance? During involuntary contractions induced by whole-body vibration, there were augmented blood pressure and spontaneous baroreflex responses in obese compared with lean women. This finding is suggestive of an overactive mechanoreflex in the exercise-induced hypertensive response in obesity. Passive contractions did not elicit differential heart rate responses in obese compared with lean women, implying other mechanisms for the blunted heart rate response reported during voluntary exercise in obesity. In obesity, the exaggerated blood pressure (BP) response to exercise is linked to hypertension, yet the mechanisms are not fully elucidated. In this study, we examined whether involuntary mechanical oscillations, induced by whole-body vibration (WBV), elicit greater haemodynamic responses and altered neural control of BP in obese versus lean women. Twenty-two normotensive, premenopausal women (12 lean and 10 obese) randomly underwent a passive WBV (25 Hz) and a control protocol (similar posture without WVB). Beat-by-beat BP, heart rate, stroke volume, systemic vascular resistance, cardiac output, parasympathetic output (evaluated by heart rate variability) and spontaneous baroreceptor sensitivity (sBRS) were assessed. We found that during WBV, obese women exhibited an augmented systolic BP response compared with lean women that was correlated with body fat percentage (r = 0.77; P < 0.05). The exaggerated BP rise was driven mainly by the greater increase in cardiac output index in obese versus lean women, associated with a greater stroke volume index in obese women

    To examine the association between body mass index (BMI), use of menopausal hormone therapy (HT), and incidence of uterine fibroids in postmenopausal women, 610,604 postmenopausal women without prior hysterectomy or diagnosis of fibroids were followed as part of a large United Kingdom prospective cohort study. We used Cox regression models to calculate adjusted relative risks (RRs) of surgically-confirmed fibroids (defined as a hospital admission with uterine fibroids as a primary diagnosis with a related surgical procedure), in relation to BMI and use of HT. During an average of 11.4 years of follow-up, 3561 women were admitted to hospital with surgically-confirmed fibroids. Five-year incidence rates decreased with age, from 0.50% (1 in 200 women) at age 50-54, to 0.11% (1 in 1000 women) at age 75-79. The 5-year rate in postmenopausal women aged 50-54 was about a quarter that seen in premenopausal women of the same age (1 in 200 vs. 1 in 50). Compared with normal weight women, obese women had a RR of surgically-detected fibroids of 1.46 (95% CI 1.33-1.59; p < 0.0001). HT use was associated with a RR of 2.33 (95% CI 2.18-2.49; p < 0.0001) in ever versus never users. When we analysed HT use and BMI together, obese vs. normal weight never users had a RR of 2.00 (95% CI 1.77-2.26): the highest risks were seen in women who were obese and had ever used HT, RR = 3.30 (95% CI 2.88-3.79). Uterine fibroids continue to occur in postmenopausal women; obesity and hormone therapy use are important modifiable risk factors. PMID:25784364

    Background Obesity is a growing problem in lower income countries particularly among women. There are few studies exploring individual socioeconomic status indicators in depth. This study examines the interaction of education and wealth in relation to obesity, hypothesising that education protects against the obesogenic effect of wealth. Methods Four datasets of women of reproductive age from the Egyptian Demographic and Health Surveys spanning the period 1992–2008 are used to examine two distinct time periods: 1992/95 (N = 11097) and 2005/08 (N = 23178). The association in the two time periods between education level and household wealth in relation to the odds of being obese is examined, and the interaction between the two socioeconomic indicators investigated. Estimates are adjusted for age group and area of residence. Results An interaction was found between the association of education and wealth with obesity in both time periods (P-value for interaction <0.001). For women with the lowest education level, moving up one wealth quintile was associated with a 78% increase in the odds of obesity in 1992/95 (OR; 95%CI: 1.78; 1.65,1.91) and a 33% increase in 2005/08 (OR; 95%CI: 1.33; 1.26,1.39). For women with the highest level of education, there was little evidence of an association between wealth and obesity (OR; 95%CI: 0.82; 0.57,1.16 in 1992/95 and 0.95; 0.84,1.08 in 2005/08). Obesity levels increased most in women who were in the no/primary education, poorest wealth quintile and rural groups (absolute difference in prevalence percentage points between the two time periods: 20.2, 20.1, and 21.3 respectively). Conclusion In the present study, wealth appears to be a risk factor for obesity in women with lower education levels, while women with higher education are protected. The findings also suggest that a reversal in the social distribution of obesity risk is occurring which can be explained by the large increase in obesity levels in lower

    Objectives Women with type 2 diabetes (T2D) show greater rates of mortality due to ischemic heart disease than men with T2D. We aimed to examine cardiovascular and autonomic function responses to isometric handgrip (IHG) exercise between men and women with T2D, before and after an exercise training program. Materials/Methods Hemodynamic responses were measured in 22 men and women with T2D during and following a 3-minute IHG test, and before and after 16 wks of aerobic exercise training. Results Women had a smaller decrease in mean arterial pressure (MAP) and systolic blood pressure (BP) during recovery from IHG (ΔMAPREC) than men pre- and post-training (P<0.05). Men showed a greater reduction in diastolic BP during recovery from IHG (P<0.05), and exercise training improved this response in men but not in women (men, pre-training: −13.9±1.8, post-training: −20.5±5.3 mmHg vs. women, pre-training: −10.7±1.7, post-training: −4.1±4.9 mmHg; P<0.05). Men had a greater reduction in sympathetic modulation of vasomotor tone (P<0.05), as estimated by blood pressure variability, following IHG. This response was accentuated after training, while this training effect was not seen in women. Post-training ΔMAPREC was correlated with recovery of low frequency component of the BP spectrum (ΔLFSBPrec, r=0.52, P<0.05). Conclusions Differences in BP recovery immediately following IHG may be attributed to gender differences in cardiovascular autonomic modulation. An improvement in these responses occurs following aerobic exercise training in obese men, but not in obese women with T2D which reflects a better adaptive autonomic response to exercise training.

    BACKGROUND Many observational studies indicate higher oral contraceptive failure among obese women, but most clinical trials and physiological studies do not support these differences. Limited data indicate higher failure rates among obese contraceptive patch users. Data regarding contraceptive vaginal ring (CVR) performance in obese women are needed. METHODS 20 normal weight (BMI 19.0–24.9, median 21.65) and 20 obese (BMI 30.0–39.9, median 33.7) women enrolled in a prospective study of ethinyl estradiol (EE) and etonorgestrel (ENG) pharmacokinetics and of ovarian follicle development, endometrial thickness, and bleeding patterns, all measured biweekly during the second cycle of CVR use. RESULTS Thirty-seven women completed follow-up. Mean day 0–21 EE concentrations were lower among obese versus normal weight women (15.0 versus 22.0 pg/mL, respectively. p = 0.004), while ENG concentrations were similar (1138 versus 1256 pg/mL, respectively. p = 0.39). Follicular development was minimal in both groups, with only five women achieving a maximum follicle diameter > 13mm at any time during 3 weeks follow-up (3 normal weight and 2 obese women); these women had serum progesterone levels < 1.0. Obese women reported more bleeding or spotting than normal weight women (3.6 versus 1.4 days, respectively. p = 0.01). CONCLUSIONS While obese women had lower EE levels during CVR use, they had excellent suppression of ovarian follicle development, similar to normal weight women. This predicts that CVR effectiveness will be similar in women with a BMI up to 39.9. The lower serum EE levels in the obese women may explain the greater reported bleeding or spotting days.

    Background Previous studies have revealed that sleep duration is linked to both obesity and hypertension. Here, we evaluated the association between sleep duration and hypertension in obese and non-obese premenopausal women using representative national survey data from the Korean population. Methods A total of 4,748 subjects over 20 years of age from the Korean National Health and Nutrition Examination Survey from 2010 to 2012 were included. To control for risk factors, multivariable logistic regression was used to calculate the adjusted odds ratios and 95% confidence intervals of hypertension across the following sleep duration categories: <6, 6-8, and >8 h/d. Results Among the participants, 367 subjects (7.7%) had hypertension. Their mean sleep duration was 7 hours. In the non-obese subjects, after controlling for potential confounding variables, the odds ratio for hypertension was 1.86 fold greater in those with a sleep duration of <6 hours (odds ratio, 1.79; 95% confidence interval, 1.05 to 3.03) as compared to those who slept for 6.8 hours. However, there was no association between sleep duration and the risk of hypertension in obese subjects. Long sleep duration (over 8 h/d) was not associated with hypertension in either the non-obese or the obese subjects in this study. Conclusion Short sleep duration (less than 6 h/d) may be a significant risk factor for hypertension in non-obese premenopausal women. However, there is no association between sleep duration and the risk of hypertension in obese women. PMID:27073613

    Introduction. Obesity is common among reproductive age women and disproportionately impacts racial/ethnic minorities. Our objective was to assess racial/ethnic differences in obesity-related dietary behaviors among pregnant and postpartum women, to inform peripartum weight management interventions that target diverse populations. Methods. We conducted a cross-sectional survey of 212 Black (44%), Hispanic (31%), and White (25%) women, aged ≥ 18, pregnant or within one year postpartum, in hospital-based clinics in Baltimore, Maryland, in 2013. Outcomes were fast food or sugar-sweetened beverage intake once or more weekly. We used logistic regression to evaluate the association between race/ethnicity and obesity-related dietary behaviors, adjusting for sociodemographic factors. Results. In adjusted analyses, Black women had 2.4 increased odds of fast food intake once or more weekly compared to White women (CI = 1.08, 5.23). There were no racial/ethnic differences in the odds of sugar-sweetened beverage intake. Discussion. Compared with White or Hispanic women, Black women had 2-fold higher odds of fast food intake once or more weekly. Black women might benefit from targeted counseling and intervention to reduce fast food intake during and after pregnancy. PMID:27298738

Attention to reducing obesity before, during and after pregnancy is essential for mothers and their offspring. Preconception weight loss is difficult given that many pregnancies are unplanned. Interventions aimed at limiting gestational weight gain have produced minimal maternal and infant outcomes. Therefore, increased research to develop evidence-based clinical practice is needed to adequately care for obese pregnant women especially during antenatal care. This review evaluates the current evidence of obesity interventions during pregnancy various including weight loss for safety and efficacy. Recommendations are provided with the end goal being a healthy pregnancy, optimal condition for breastfeeding and prevent the progression of obesity in future generations.

    Obesity in humans has been associated with altered autonomic nervous system activity. The objective of this study was to examine the relationship between autonomic function and body fat distribution in 16 obese, postmenopausal women using power spectrum analysis of heart rate variability. Using this technique, a low frequency peak (0.04-0.12 Hz) reflecting mixed sympathetic and parasympathetic activity, and a high frequency peak (0.22-0.28 Hz) reflecting parasympathetic activity, were identified from 5-minute consecutive heart rate data (both supine and standing). Autonomic activity in upper body (UBO) vs. lower body obesity (LBO)(by waist-to-hip ratio) and subcutaneous vs. visceral obesity (by CT scan) was evaluated. Power spectrum data were log transformed to normalize the data. The results showed that standing, low-frequency power (reflecting sympathetic activity) and supine, high-frequency power (reflecting parasympathetic activity) were significantly greater in UBO than in LBO, and in visceral compared to subcutaneous obesity. Women with combined UBO and visceral obesity had significantly higher cardiac sympathetic and parasympathetic activity than any other subgroup. We conclude that cardiac autonomic function as assessed by heart rate spectral analysis varies in women depending on their regional body fat distribution. PMID:8787938

    Pregnancy is now considered to be an important risk factor for new or persistent obesity among women during the childbearing years. High gestational weight gain is the strongest predictor of maternal overweight or obesity following pregnancy. A growing body of evidence also suggests that both high and low gestational weight gains are independently associated with an increased risk of childhood obesity, suggesting that influences occurring very early in life are contributing to obesity onset. In response to these data, the United States Institute of Medicine (IOM) revised gestational weight gain guidelines in 2009 for the first time in nearly two decades. However, less than one-third of pregnant women achieve guideline-recommended gains, with the majority gaining above IOM recommended levels. To date, interventions to optimize pregnancy weight gains have had mixed success. In this paper, we summarize the evidence from human and animal studies linking over-nutrition and under-nutrition in pregnancy to maternal and child obesity. Additionally, we discuss published trials and ongoing interventions to achieve appropriate gestational weight gain as a strategy for obesity prevention in women and their children. PMID:21851516

    ABSTRACT Background: For many developing countries, obesity and its sequelae have become a challenge of a magnitude similar to hunger and undernutrition. The main objective of this study was, therefore, to investigate the weight status of women in rural Tanzania with reference to season as well as the link between women's weight, food consumption, and attitudes toward obesity. Methods: Three cross-sectional surveys in 3 different seasons within 1 year interviewed the same 210 women, ages 17–45 years, from 3 rural districts of northeastern and central Tanzania. These surveys assessed body mass index (BMI), food intake, and dietary diversity through 24-hour recalls, women's attitudes toward obesity, vegetable production, and socioeconomic status. Results: Although 71% of the women had a normal BMI, 7% were underweight, 16% overweight, and 6% obese. The BMI was correlated with the Dietary Diversity Score (DDS), the Food Variety Score (FVS), with the consumption of foods from the food groups “bread/cakes,” “sugar,” and “tea,” and with the production of exotic vegetables. In a multiple regression model, FVS was directly associated with BMI. When asked to describe the typical characteristics of an obese person, women mentioned more negative than positive characteristics. Conclusion: The prevalence of overweight and obesity was 3 times higher than that of underweight. Apparently, even in rural areas of Tanzania, a nutrition transition is underway. No direct association was identified between vegetable consumption and BMI. Although this study did not assess behavioral factors, such behavioral factors as activity levels as well as attitudes need to be considered, even in rural settings, to address all facets of malnutrition.

    Obesity and type 2 diabetes have been shown to alter the insulin sensitivity of glucose and protein metabolism in middle-aged women. We aimed to determine whether these findings translate to the elderly who are at increased risk of muscle loss. We assessed whole-body protein (1-(13)C-leucine) and glucose (3-(3)H-glucose) kinetics in 10 healthy (age: 71.6±1.8years; BMI: 23.2±0.8kg/m(2)), 8 obese (age: 72.9±1.3; BMI: 33.1±1.0) and 8 obese well-controlled type 2 diabetic (age: 69.8±1.6; BMI: 34.4±1.5) elderly women in the postabsorptive state and during a hyperinsulinemic, euglycemic, isoaminoacidemic clamp. All subjects followed an isoenergetic, protein-controlled diet for 6days preceding the clamp. The net protein anabolic response to hyperinsulinemia was similarly blunted in obese (0.08±0.06) and obese type 2 diabetic women (0.06±0.04) compared to healthy women (0.24±0.05μmol·kg fat free mass(-1)·min(-1); ANOVA p=0.018). In contrast, the insulin-mediated glucose disposal (healthy: 9.72±0.67) was decreased with obesity (6.96±0.86) and further with diabetes (5.23±0.27mg·kg fat free mass(-1)·min(-1); ANOVA p<0.001). Endogenous glucose production was not completely suppressed during the clamp only in diabetic women. Thus, the glucose infusion rate was the lowest in this group. Obese elderly women with and without type 2 diabetes have a similar degree of insulin resistance of protein anabolism, despite worse glucose metabolism in type 2 diabetes. Similar to previous findings in middle-aged women, obesity exerted a blunting effect on protein anabolism, which may contribute to the development of sarcopenic obesity. Our results suggest that the presence of type 2 diabetes at an advancing age does not further aggravate this effect. PMID:26068615

    Heightened food cue-reactivity in overweight and obese individuals has been related to aberrant functioning of neural circuitry implicated in motivational behaviours and reward-seeking. Here we explore the neurophysiology of visual food cue-reactivity in overweight and obese women, as compared with normal weight women, by assessing differences in cortical arousal and attentional processing elicited by food and neutral image inserts in a Stroop task with record of EEG spectral band power and ERP responses. Results show excess right frontal (F8) and left central (C3) relative beta band activity in overweight women during food task performance (indicative of pronounced early visual cue-reactivity) and blunted prefrontal (Fp1 and Fp2) theta band activity in obese women during office task performance (suggestive of executive dysfunction). Moreover, as compared to normal weight women, food images elicited greater right parietal (P4) ERP P200 amplitude in overweight women (denoting pronounced early attentional processing) and shorter right parietal (P4) ERP P300 latency in obese women (signifying enhanced and efficient maintained attentional processing). Differential measures of cortical arousal and attentional processing showed significant correlations with self-reported eating behaviour and body shape dissatisfaction, as well as with objectively assessed percent fat mass. The findings of the present study suggest that heightened food cue-reactivity can be neurophysiologically measured, that different neural circuits are implicated in the pathogenesis of overweight and obesity, and that EEG techniques may serve useful in the identification of endophenotypic markers associated with an increased risk of externally mediated food consumption.

    We investigated the relationship between circulating leptin and osteoprotegerin (OPG) levels and insulin resistance assessed by HOMA-IR in premenopausal obese and normal weight women. Thirty four obese women (age 31 +/- 8 years) (BMI 35 +/- 4 kg/m(2)) with 19 healthy controls (age 31 +/- 7 years) (BMI <25 kg/m(2)) (BMI 21 +/- 2 kg/m(2)) were included in the study. Women were healthy and had no osteoporosis. Circulating leptin levels were significantly higher in obese women (17.11 +/- 2.05 ng/mL vs. 8.38 +/- 4.71 ng/mL, p <0.0001) and decreased OPG levels were found (14.7 +/- 7.15 pg/mL vs. 19.17 +/- 6.37 pg/mL, p = 0.03). Leptin showed a positive correlation with BMI (r = 0.851, p <0.0001), waist-to-hip ratio (r = 0.692, p <0.0001), fasting insulin (r = 0.441, p <0.001), HOMA-IR (r = 0.412, p = 0.002), fibrinogen (r = 0.387, p = 0.004), uric acid (r = 0.293, p = 0.033), hematocrit (r = 0.394, p = 0.003), systolic (r = 0.504, p <0.0001), and diastolic blood pressure (r = 0.363, p = 0.008). OPG showed a negative correlation with insulin (r = -0.341, p = 0.013) and HOMA-IR (r = -0.324, p = 0.018). In obese women group, the regression equation of HOMA-IR was (HOMA-IR = [0.095 x leptin]-[0.051 x OPG] + 1.71). However, there was no relation between leptin and OPG levels. In conclusion, circulating leptin and OPG levels were related to insulin resistance in premenopausal obese women. However, leptin had no interference in OPG in premenopausal women. PMID:17923273

    Small-for-gestational-age (SGA) and large-for gestational-age (LGA) infants are associated with increased adverse outcomes. While studies have estimated the association of gestational weight gain with birth weight in obese women, estimates are lacking by obesity class and diabetic status. A population-based historical cohort study of 66,010 obese pregnant women in Missouri delivering liveborn, singleton, term infants in 2002–2008 was conducted. Adjusted odds ratios for SGA and LGA infants were calculated for gestational weight gain categories with multiple logistic regression using the revised Institute of Medicine(IOM) recommended 11–20 pounds as the reference group. A weight gain of 3–10 pounds was not significantly associated with an increased risk of an SGA infant compared to 11–20 pounds in 5/6 obesity class/diabetic status combinations.The exception was Class I Obese non-diabetic women(adjusted odds ratio = 1.28, 95 % confidence interval 1.07, 1.52). When lower amounts of weight gain were considered, diabetic women who gained ≤2 pounds (including women who lost weight) did not have a significantly increased risk of an SGA infant compared to diabetic women who gained 11–20 pounds in any obesity class. Weight gains less than 11–20 pounds were significantly associated with a decreased risk of an LGA infant in 5/6 obesity class/diabetic status combinations. Weight gains lower than the IOM recommendation of 11–20 pounds during pregnancy for obese women generally were significantly associated with decreased risk of LGA infants without being significantly associated with increased risk of SGA infants and differed by obesity class and diabetic status.

    Background: Obesity is a major health problem worldwide for which conventional therapy efficacy is limited. Traditional Chinese medicine, particularly body acupoint stimulation, provides an alternative, effective, and safe therapy for this medical challenge. The present study was designed to compare the effects of distinct methods to stimulate the same set of acupoints, on anthropometric and biochemical parameters in obese women. Materials and Methods: Ninety-nine obese women were randomly assigned to six groups of treatment: Acupuncture with moxibustion, long needle acupuncture with moxibustion, electroacupuncture (EA), EA with moxibustion, embedded catgut with moxibustion (CGM) and sham acupuncture as control. Obesity-related parameters, including body weight, body mass index (BMI), waist and hip circumferences, waist/hip ratio, biochemical parameters (triglycerides, cholesterol, glucose, insulin) and homeostasis model of assessment - insulin resistance (HOMA-IR) index, were determined before and after each treatment. Results: Body weight and BMI were significantly reduced in response to all treatments. Interestingly, acupoint catgut embedding therapy combined with moxibustion was the only treatment that produced a significant reduction in body weight (3.1 ± 0.2 kg, P < 0.001), BMI (1.3 ± 0.1 kg/m2, P < 0.001), insulin (3.5 ± 0.8 mcU/ml, P < 0.1) and HOMA-IR (1.4 ± 0.2 units, P < 0.01) in comparison with sham group. Furthermore, this treatment was able to bring back obese women to a state of insulin sensitivity, indicating that acupoint catgut embedding therapy combined with moxibustion could be useful as a complementary therapy to reduce the risk of diabetes associated to obesity in women. Conclusion: Overall, our results confirmed the effectiveness of acupoints stimulation to assist in the control of body weight in women. They also highlighted the more favorable effects of embedded catgut-moxibustion combination that may be due to the extended and

    BACKGROUND & AIMS The study of intrinsic fluctuations in the blood oxygen level-dependent signal of functional magnetic resonance imaging can provide insight into the effect of physiologic states on brain processes. In an effort to better understand the brain–gut communication induced by the absorption and metabolism of nutrients in healthy lean and obese individuals, we investigated whether ingestion of nutritive and non-nutritive sweetened beverages differentially engages the hypothalamus and brainstem vagal pathways in lean and obese women. METHODS In a 2-day, double-blind crossover study, 11 lean and 11 obese healthy women underwent functional magnetic resonance imaging scans after ingestion of 2 beverages of different sucrose content, but identical sweetness. During scans, subjects rested with eyes closed. RESULTS Blood oxygen level-dependent fluctuations demonstrated significantly greater power in the highest frequency band (slow-3: 0.073–0.198 Hz) after ingestion of high-sucrose compared with low-sucrose beverages in the nucleus tractus solitarius for both groups. Obese women had greater connectivity between the right lateral hypothalamus and a reward-related brain region and weaker connectivity with homeostasis and gustatory-related brain regions than lean women. CONCLUSIONS In a functional magnetic resonance imaging study, we observed sucrose-related changes in oscillatory dynamics of blood oxygen level-dependent fluctuations in brainstem and hypothalamus in lean and obese women. The observed frequency changes are consistent with a rapid vagally mediated mechanism due to nutrient absorption, rather than sweet taste receptor activation. These findings provide support for altered interaction between homeostatic and reward networks in obese individuals. PMID:24480616

    Studies on small samples or in single units applying specific treatment programmes found an association between some personality traits and attrition and weight loss in individuals treated for obesity. We aimed to investigate whether pre-treatment personality traits were associated with weight loss outcomes in the general population of women with obesity. Attrition and weight loss outcomes after 12 months were measured in 634 women with obesity (mean age, 48; body mass index (BMI), 37.8 kg m(-2)) seeking treatment at eight Italian medical centres, applying different medical/cognitive behavioural programmes. Personality traits were assessed with the Temperament and Character Inventory (TCI), eating disorder features with the Binge Eating Scale (BES) and Night Eating Questionnaire (NEQ). Within the 12-month observation period, 32.3% of cases were lost to follow-up. After adjustment for demographic confounders and the severity of eating disorders, no TCI personality traits were significantly associated with attrition, while low scores of the novelty seeking temperament scale remained significantly associated with weight loss ≥ 10% (odds ratio, 0.983; 95% confidence interval, 0.975-0.992). Additional adjustment for education and job did not change the results. We conclude that personality does not systematically influence attrition in women with obesity enrolled into weight loss programmes in the community, whereas an association is maintained between novelty seeking and weight loss outcome. Studies adapting obesity interventions on the basis of individual novelty seeking scores might be warranted to maximize the results on body weight. PMID:26256916

    Blood levels of glucose and immunoreactive insulin were assessed in women with android and gynoid types of obesity or normal body weight (control group) in the dynamics of oral glucose tolerance test in the morning and in the evening. In the control group, the mean concentrations of glucose and immunoreactive insulin were significantly higher in the evening at all test terms (0, 60 and 120 min), which is indicative of physiological insulin resistance in the evening. In the group of women with gynoid obesity, no difference in the levels of glucose and immunoreactive insulin was revealed in the morning and evening tests, but in the evening tests, glucose (60 and 120 min) and immunoreactive insulin (120 min) levels were lower than in the control group. In the group of women with android obesity, the evening glucose level on minutes 60 and 120 of the test was higher than in the morning, but immunoreactive insulin did not vary throughout the day and on minutes 60 and 120 it surpassed the corresponding parameter in the control group by 2-4 times. In case of gynoid obesity, glucose load was followed by hyperinsulinemia and hypoglycemia; in android obesity, it was followed by hyperinsulinemia, hyperglycemia, and insulin resistance irrespective of the time of the day.

    Physical activity is essential in obesity management, but exercise capacity is compromised in obese individuals due to the excessive body mass, impacting on body movement's energetics, and to the dysfunctions of regulatory mechanisms, affecting cardiovascular responses. This study aims to compare the energetics and cardiovascular responses of walking and cycling in obese women, and to formulate recommendations regarding the most suitable type of exercise for obesity. Fifteen obese (OB) and six normal weight (NW) women exercised on treadmill (TM) and cycle ergometer (CE). During both exercise modalities, metabolic rate was higher in OB than in NW and correlated with measures of body mass. Leg movement metabolic rate during cycling depended upon individual adiposity, and when accounted for, mechanical efficiency was similar in the two groups. When accounting for extra mass, differences in metabolic rate among groups are abolished for CE, indicating no obesity impairment of muscle efficiency, but not for TM, suggesting that differences in biomechanics may explain the higher net cost of transport of OB. In both groups, HR was higher during CE than TM at the same oxygen uptake (VO(2)), but in OB the HR increment over VO(2) was greater for CE than for TM. Therefore, due to different cardiovascular responses to TM and CE in OB, walking is more convenient, enabling OB to attain target energy expenditure at lower HR or in a shorter time. PMID:18496708

    The aim of this study was to determine whether there is an association between leukocyte telomere length (LTL), and estrogen level, oxidative stress, cardiovascular disease (CVD) risk factors, and cardiorespiratory fitness (CRF) in pre- and postmenopausal obese women. Fifty-four obese women (premenopausal, n=25; postmenopausal, n=29) were selected to participate in this study. The outcome measurements in the pre- and postmenopausal groups were compared using independent t-tests and Pearson correlation analysis. The estrogen level (P<0.001), LTL (P<0.05), high-density lipoprotein level (P<0.05), and CRF (P<0.001) were higher in premenopausal women than in postmenopausal women. The body fat percentage (P<0.05) and triglyceride concentration (P<0.05) were lower in premenopausal women than in postmenopausal women. There were no significant associations between LTL, CVD risk, CRF, and oxidative stress and antioxidant enzyme activity in pre-menopausal women. The body mass index (BMI) and body fat percent-age in postmenopausal women were negatively associated with LTL (P<0.05). When all women were considered (i.e., both pre- and post-menopause), the BMI, percentage of fat, and waist circumference had a negative association with LTL (P<0.05), and estrogen levels were positively associated with LTL (P<0.05). Decreased estrogen levels after menopause, a pivotal factor in the biology of aging, and obesity were more associated with shorter telomere lengths in pre- and postmenopausal women than aerobic capacity and other CVD risk factors.

    Stress-related cortisol secretion has been linked to increased appetite and subsequent food intake in overweight individuals. The present study addresses this relationship in a repeated-measures randomized controlled laboratory experiment. Nineteen obese women were compared to 36 normal weight controls with respect to stress-induced salivary cortisol and laboratory eating behavior, measured by a universal eating monitor. The trier social stress test served as stressor. Stress-induced cortisol levels were significantly higher in the obese compared to the normal weight controls. Unexpectedly, a corresponding increase in laboratory food intake was not detected. The results are interpreted and discussed with regard to restrained eating, which was found to be present to a significant degree in the obese women. PMID:25827493

    2013-01-01

    Background The menopause is associated with a tendency to gain weight. Several alterations in fat deposits occur, leading to changes in the distribution of body fat. There are strong indications that, in middle age, obesity is associated with increased mortality. This study set out to determine the factors associated with the prevalence of overweight and abdominal obesity in postmenopausal women in a population-based study in Brazil. Methods The sample included 456 women, aged 45–69 years, residing in the urban area of Maringa, Parana. Systematic sampling, with a probability proportional to the size of the census sector, was performed. Behavioral, economic, and sociodemographic data were collected, and body mass index (BMI) and waist circumference (WC) were determined. Results According to BMI criteria (≥25.0 kg/m2), 72.6% of the women were overweight, and according to WC (≥88 cm), 63.6% had abdominal obesity. Based on logistic regression analysis, the factors that were most closely associated with overweight were: having three or more children (odds ratio (OR): 1.78; 95% confidence interval (CI): 1.06–3.00); and not taking hormone replacement therapy (OR: 1.69; 95% CI: 1.06–2.63). The prevalence of abdominal obesity was positively associated with greater parity (OR: 1.34, 95% CI: 1.05–1.72) and age older than 65 years (OR: 1.50; 95% CI: 1.03–2.19). Conclusions This study found that the prevalences of overweight and abdominal obesity were higher for postmenopausal women who had three or more children. Age over 65 years was also a risk factor for abdominal obesity and no use of hormonal replacement therapy was a risk factor for overweight. PMID:24228934

    Mobile mammography services are typically offered as a means to increase access and adherence to mammography screenings. As mobile mammography becomes a viable strategy to increase screening, a 3 year study of such a state-wide program in WV found surprisingly high rates of obesity within the study population. Thus, the objectives were to: (1) describe the demographic characteristics and comorbidities of women who utilized the WV program, and (2) determine the association between body mass index (BMI) and personal health and screening history, preventive care and wellness behaviors, nutrition and exercise behaviors, and demographics. Data collected from 1,099 women, age 40 and above, were analyzed using descriptive statistics, bivariate analyses, and a multivariate regression model. The majority (60.4 %) were married, had an income <$25,000 (59.2 %), and had health insurance (53.5 %). Major comorbidities were hypertension (49 %) and high cholesterol (43.9 %). Based on BMI scores, 884 participants were either overweight (26.6 %), mildly obese (27.7 %), moderately obese (15.1 %), or severely obese (11.1 %). Bivariate analyses indicated that increasing BMI was significantly associated with factors such as having hypertension or diabetes, limited daily activities, perceived health, and not smoking or drinking. The regression model was significant (p < 0.001; R2 = 0.425) indicating that women who engaged in preventive care behaviors were less likely to be obese than those who did not. The WV mobile mammography program appeared to attract women who were disproportionately obese and had multiple comorbidities, thus providing a great opportunity for targeted interventions related to improving preventive care and screening behaviors.

    Background Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with increased risk of stroke and death. Obesity is an independent risk factor for AF, but modifiers of this risk are not well known. We studied the roles of obesity, physical activity, and their interaction in conferring risk of incident AF. Methods and Results The Women's Health Initiative (WHI) Observational Study was a prospective observational study of 93 676 postmenopausal women followed for an average of 11.5 years. Incident AF was identified using WHI‐ascertained hospitalization records and diagnostic codes from Medicare claims. A multivariate Cox's hazard regression model adjusted for demographic and clinical risk factors was used to evaluate the interaction between obesity and physical activity and its association with incident AF. After exclusion of women with prevalent AF, incomplete data, or underweight body mass index (BMI), 9792 of the remaining 81 317 women developed AF. Women were, on average, 63.4 years old, 7.8% were African American, and 3.6% were Hispanic. Increased BMI (hazard ratio [HR], 1.12 per 5‐kg/m2 increase; 95% confidence interval [CI], 1.10 to 1.14) and reduced physical activity (>9 vs. 0 metabolic equivalent task hours per week; HR, 0.90; 95% CI, 0.85 to 0.96) were independently associated with higher rates of AF after multivariate adjustment. Higher levels of physical activity reduced the AF risk conferred by obesity (interaction P=0.033). Conclusions Greater physical activity is associated with lower rates of incident AF and modifies the association between obesity and incident AF. PMID:25142057

    Objective To describe how maternal obesity prevalence varies by established international and South Asian specific BMI cut-offs in women of Pakistani origin and investigate whether different BMI thresholds can help to identify women at risk of adverse pregnancy and birth outcomes. Design Prospective bi-ethnic birth cohort study (The Born in Bradford Cohort). Setting Bradford, a deprived city in the North of the UK. Participants 8,478 South Asian and White British pregnant women participating in the Born in Bradford cohort study Main outcome measures Maternal obesity prevalence; prevalence of known obesity related adverse pregnancy outcomes: mode of birth, hypertensive disorders of pregnancy (HDP), gestational diabetes, macrosomia, pre-term births. Results Application of South Asian BMI cut-offs increased prevalence of obesity in Pakistani women from 18.8% (95% CI 17.6 to 19.9) to 30.9% (95% CI 29.5 to 32.2). With the exception of pre-term births, there was a positive linear relationship between BMI and prevalence of adverse pregnancy and birth outcomes, across almost the whole BMI distribution. Risk of gestational diabetes and HDP increased more sharply in Pakistani women after a BMI threshold of at least 30kg/m2, but there was no evidence of a sharp increase in any risk factors at the new, lower thresholds suggested for use in South Asian women. BMI was a good single predictor of outcomes (Area Under the Receiver Operating Curve: 0.596 to 0.685 for different outcomes); prediction was more discriminatory and accurate with BMI as a continuous variable than as a binary variable for any possible cut-point. Conclusion Applying the new South Asian threshold to pregnant women would markedly increase those referred for monitoring and lifestyle advice. However, our results suggest that lowering the BMI threshold in South Asian women would not improve the predictive ability for identifying those at risk of adverse pregnancy outcomes. PMID:23797188

    Ghrelin regulates homeostatic food intake, hedonic eating, and is a mediator in the stress response. In addition, ghrelin has metabolic, cardiovascular, and anti-aging effects. This cross-sectional study examined associations between total plasma ghrelin, caloric intake based on 3 day diet diaries, hedonic eating attitudes, stress-related and metabolic factors, and leukocyte telomere length in overweight (n=25) and obese women (n=22). We hypothesized associations between total plasma ghrelin and eating behaviors, stress, metabolic, cardiovascular, and cell aging factors among overweight women, but not among obese women due to lower circulating ghrelin levels and/or central resistance to ghrelin. Confirming previous studies demonstrating lowered plasma ghrelin in obesity, ghrelin levels were lower in the obese compared with overweight women. Among the overweight, ghrelin was positively correlated with caloric intake, giving in to cravings for highly palatable foods, and a flatter diurnal cortisol slope across 3 days. These relationships were non-significant among the obese group. Among overweight women, ghrelin was negatively correlated with insulin resistance, systolic blood pressure, and heart rate, and positively correlated with telomere length. Among the obese subjects, plasma ghrelin concentrations were negatively correlated with insulin resistance, but were not significantly correlated with blood pressure, heart rate or telomere length. Total plasma ghrelin and its associations with food intake, hedonic eating, and stress are decreased in obesity, providing evidence consistent with the theory that central resistance to ghrelin develops in obesity and ghrelin’s function in appetite regulation may have evolved to prevent starvation in food scarcity rather than cope with modern food excess. Furthermore, ghrelin is associated with metabolic and cardiovascular health, and may have anti-aging effects, but these effects may be attenuated in obesity. PMID:24462487

    Despite well-established variations in the health risks posed by visceral vs. subcutaneous abdominal (SCABD) fat depots, surprisingly little is known on the differences within a given adipose tissue (AT) among severely obese patients displaying varying metabolic dysfunction. We thus compared, by quantitative PCR, the expression profile of a number of genes in the SCABD, omental (OME), and mesenteric (MES) depots of severely obese women with (DYS; n = 25) or without (NDYS; n = 23) a dysmetabolic profile. Fasting insulinemia and HOmeostasis Model Assessment-insulin resistance (HOMA-IR) were higher and plasma adiponectin level lower in DYS women (p < 0.05). Among enzymes involved in fatty acid metabolism and local cortisol production, phosphodiesterase-3B expression was lower in SCABD and MES fat, while 11β-hydroxysteroid dehydrogenase type 1 mRNA levels were higher in visceral depots of DYS women (p < 0.05). Regarding vascular homeostasis and inflammation, plasminogen activator inhibitor-1 and interleukin-6 mRNA levels were higher in OME fat, while adiponectin expression was lower in SCABD and OME ATs of DYS women (p < 0.05). Finally, HOMA-IR was positively associated with SCABD AT IL6 mRNA, only in DYS women (r = 0.47; p < 0.05). In conclusion, although metabolic and secretory characteristics of all depots vary with subjects' metabolic profile, we find little evidence for a protective role of SCABD AT and no evidence for a further deleterious role of MES fat in DYS vs. NDYS severely obese women. Regional variation in the overall gene expression revealed that OME and MES fat were more closely related to each other in DYS women, while SCABD and MES depots showed greater resemblance in NDYS women.

    Background Maternal obesity is a well established risk factor for gestational diabetes but it is not known if the pattern of maternal fat distribution predicts adverse pregnancy outcomes. Methods Body composition was assessed by bioimpedance using Inbody 720® in 302 consecutive obese pregnant women attending a weight management clinic. The relation of visceral fat mass and total percentage body fat with the development of gestational diabetes and perinatal outcomes was evaluated. Results Women developing gestational diabetes (Group 1; n = 72) were older, had higher body mass indices and greater central obesity (waist:hip ratio, visceral fat mass) compared with those remaining normoglycaemic. Visceral fat mass, but not percentage body fat, correlated with fasting glucose in all patients (r = 0.2, p < 0.001) and particularly those in Group 1 (r = 0.35, p = 0.002). Visceral fat mass, but not percentage body fat, also correlated strongly with glycaemia, particularly in Group 1 (r = 0.47, p < 0.0001). Visceral fat mass also showed a weak but significant correlation with baby weight (r = 0.17, p = 0.01). Discussion Central obesity, as assessed by early pregnancy waist:hip ratio and particularly by visceral fat mass, is a predictor of gestational diabetes in addition to classical risk factors and may help identify those obese patients at increased risk of complications.

    Anovulatory cycles and endometriosis are the main causes of female infertility. The most frequently anovulatory cycles are related to polycystic ovary syndrome (PCOS) commonly associated with obesity and hormonal disturbances in the course of obesity. Recently published studies revealed that infertility affects about one in six couples during their lifetime and is more frequent in obese. Obesity is also associated with male infertility related to erectile dysfunction, hormonal disturbances and lower semen quality. Any of these above mentioned disorder is the important risk factor of psychological disturbances and poor quality of life among women and men in the reproductive age. On the other hand the mood disorders may exacerbate the hormonal disturbances and worsen the effectiveness of infertility management. Infertility, its therapy with accompanying psychological disturbances may also significantly affect the partners relationships. The review summarize the results described in the current literature on the association between obesity and infertility and psychological disturbances as well as their impact on quality of life and sexual functioning in women and men. Moreover, the impact of infertility and psychological disturbances on partners relationships is discussed. PMID:22844280

    Objective: A major consequence of obesity is the enormous expansion of and enhanced inflammatory response seen in visceral adipose tissue. I hypothesized that the expression of inflammatory markers in visceral omental fat would correlate with the extent of visceral adiposity as measured by waist circumference or body mass index and that diabetes and hypertension, defined as subjects taking anti-hypertensive drugs, would be associated with changes in mRNA expression in visceral fat. Design and methods: The expression of 106 mRNAs by RT-PCR was examined in observational studies using extracts of omental fat of obese women undergoing bariatric surgery as well as the circulating levels of some adipokines. We also compared the mRNA levels of 65 proteins in omental fat removed during gastric bypass surgery of women with and without hypertension and those with type 2 diabetes. Results: Out of 106 mRNAs the expression of 10 mRNAs in omental fat of women not taking anti-hypertensive drugs correlated with waist circumference while 7 different mRNAs had significant correlations with circulating glucose. The correlations of waist circumference with mRNA expression were abolished, except for interleukin (IL)-1 receptor antagonist (IL-1RA), in women taking anti-hypertensive drugs. The correlations of blood glucose with omental fat mRNA expression were abolished, except for that of Akt1 and Akt2, in women taking anti-hypertensive drugs. However, the expression of 4 different mRNAs in omental fat was affected by circulating glucose in subjects taking anti-hypertensive drugs. The circulating levels of IL-1 RA, but not fatty acid binding protein 4, adipsin and phospholipase A2, correlated with both waist circumference and mRNA expression in omental fat. Conclusion: In female bariatric surgery patients, the mRNA expression of some proteins in omental fat was affected by the degree of obesity, whereas hypertension and diabetes affected a separate set of mRNAs.

    Inflammation is elevated in obese pregnant women and is associated with adverse maternal and neonatal outcomes. Maternal lipid metabolism and its relationships with maternal inflammation, insulin resistance and neonatal metabolic health are poorly understood in obese pregnant women. 18 lean (age: 26.1 ± 5.0 years, pre-pregnancy BMI: 21.5 ± 1.9 kg/m2) and 16 obese (age: 25.0 ± 4.8 years, pre-pregnancy BMI: 36.3 ± 4.3 kg/m2) women participated in this case-control study during the third trimester of pregnancy. Maternal plasma markers of insulin resistance (HOMA-IR) and inflammation (C-reactive protein (CRP)) were measured at rest, and lipid concentration and kinetics (lipid oxidation rate and lipolysis) were measured at rest, during a 30-minute bout of low-intensity (40% VO2peak) exercise, and during a recovery period. Umbilical cord blood was collected for measurement of neonatal plasma insulin sensitivity, inflammation, and lipid concentration. Neonatal body composition was measured via air displacement plethysmography. Pregnant obese women had higher plasma CRP (9.1 ± 4.0 mg/L versus 2.3 ± 1.8 mg/L, p<0.001) and higher HOMA-IR (3.8 ± 1.9 versus 2.3 ± 1.5, p=0.009) compared to pregnant lean women. Obese women had higher lipid oxidation rates during recovery from low-intensity exercise (0.13 ± 0.03 g/min versus 0.11 ±0.04 g/min, p=0.02) that was associated with higher maternal CRP (r=0.55, p=0.001). Maternal CRP was positively associated with maternal HOMA-IR (r=0.40, p<0.02) and systolic blood pressure (r=0.40, p<0.02). Maternal lipid metabolism-associated inflammation may contribute to insulin resistance and higher blood pressure in obese women during pregnancy. PMID:27239331

    The present study was planned to investigate differences in psychopathological features, eating behaviour and eating habits between obese women with and without BED. It also aimed to identify specific relationships between affective symptoms and eating behaviour in obese women with BED. Eighty-four obese women were studied (40 with BED, 44 non-BED). Psychiatric comorbidities were assessed with the structured diagnostic interview for DSM-IV (SCID). Depressive symptoms were measured with the Beck Depression Inventory (BDI) and anxiety with the state-trait anxiety inventory (STAI). Eating habits (emotional and restrained eating) were assessed by the Dutch eating behaviour questionnaire (DEBQ). Food diaries were used for assessing naturalistic eating behaviour (food intake) and mood before and after food intake. BED subjects exhibited higher levels of comorbidity (in particular mood disorders, anxiety disorders and substance-related disorders), higher depressive symptoms, trait anxiety, external and emotional eating scores than non-BED subjects. Regression analyses revealed that anxiety and emotional eating were significant predictors for BED status. In the BED group, depressive symptoms were significantly related to emotional eating and food intake and negatively related to restraint. Anxiety was significantly related to emotional eating. In general, food intake significantly enhanced mood. Mood was worse on the days with self-reported binge eating episodes than on nonbinge days. These results are discussed with regard to aetiological models for BED and for BED being a distinct diagnostic category separate from obesity. PMID:21406953

    White and minority women experience different rates of obesity in the United States. Yet our understanding of the dynamics that give rise to this gap remains limited. This article presents a conceptual framework that considers pathways leading to these different rates. It draws upon the life-course perspective, allostatic load, and the weathering hypothesis to identify pathways linking childbearing, stress, and obesity. This conceptual framework extends prior work by identifying age at first birth as an important parameter that influences these pathways. Empirical evidence to test these pathways is needed.

    An elevation in hearing thresholds and decrease in hearing sensitivity in adults, particularly due to aging, are quite common. Recent studies have shown that, apart from aging, various other factors also play a role in auditory changes. Studies on the association of hearing loss (HL) with obesity are limited in advanced age cases and present contradictions. In this study, the association between obesity and hearing thresholds in women aged 18-40 years has been assessed. Forty women diagnosed with obesity (mean age, 31.8 years) and 40 healthy non-obese female controls (mean age, 30.5 years) were included in this prospective study. Each subject was tested with low (250, 500, 1000 and 2000 Hz) and high (4000, 6000 and 8000 Hz) frequency audiometry. In the case and control groups, the average hearing thresholds at low frequencies were 16.03 ± 4.72 and 16.15 ± 2.72 (p = 0.885) for the right ear, respectively, and 16.15 ± 5.92 and 14.71 ± 3.18 (p = 0.180) for the left ear, respectively. The average hearing threshold levels at high frequencies were 20.70 ± 10.23 and 15.33 ± 3.87 (p = 0.003), respectively, for the right ear, and 22.91 ± 15.54 and 15.87 ± 4.35 (p = 0.007), respectively, for the left ear with statistical significance. This is the first report on the association of obesity with hearing threshold in women aged 18-40 years. We have demonstrated that obesity may affect hearing function, particularly that related to high frequencies. Hearing loss can be prevented by avoidance or control of obesity and its risk factors. Moreover, an auditory screening of obese cases at an early stage may provide early diagnosis of HL and may also contribute to their awareness in the fight against obesity. PMID:26429780

    Background Despite the widespread recognition that obesity in pregnant women is associated with adverse outcomes for mother and child, there is no intervention proven to reduce the risk of these complications. The primary aim of this randomised controlled trial is to assess in obese pregnant women, whether a complex behavioural intervention, based on changing diet (to foods with a lower glycemic index) and physical activity, will reduce the risk of gestational diabetes (GDM) and delivery of a large for gestational age (LGA) infant. A secondary aim is to determine whether the intervention lowers the long term risk of obesity in the offspring. Methods/Design Multicentre randomised controlled trial comparing a behavioural intervention designed to improve glycemic control with standard antenatal care in obese pregnant women. Inclusion criteria; women with a BMI ≥30 kg/m2 and a singleton pregnancy between 15+0 weeks and 18+6 weeks’ gestation. Exclusion criteria; pre-defined, pre-existing diseases and multiple pregnancy. Randomisation is on-line by a computer generated programme and is minimised by BMI category, maternal age, ethnicity, parity and centre. Intervention; this is delivered by a health trainer over 8 sessions. Based on control theory, with elements of social cognitive theory, the intervention is designed to improve maternal glycemic control. Women randomised to the control arm receive standard antenatal care until delivery according to local guidelines. All women have a 75 g oral glucose tolerance test at 27+0- 28+6 weeks’ gestation. Primary outcome; Maternal: diagnosis of GDM, according to the International Association of Diabetes in Pregnancy Study Group (IADPSG) criteria. Neonatal; infant LGA defined as >90th customised birth weight centile. Sample size; 1546 women to provide 80% power to detect a 25% reduction in the incidence of GDM and a 30% reduction in infants large for gestational age. Discussion All aspects of this protocol have been

    PubMed Central

    2011-01-01

    Background The increased prevalence of obesity in pregnant women in Australia and other developed countries is a significant public health concern. Obese women are at increased risk of serious perinatal complications and guidelines recommend weight gain restriction and additional care. There is limited evidence to support the effectiveness of dietary and physical activity lifestyle interventions in preventing adverse perinatal outcomes and new strategies need to be evaluated. The primary aim of this project is to evaluate the effect of continuity of midwifery care on restricting gestational weight gain in obese women to the recommended range. The secondary aims of the study are to assess the impact of continuity of midwifery care on: women's experience of pregnancy care; women's satisfaction with care and a range of psychological factors. Methods/Design A two arm randomised controlled trial (RCT) will be conducted with primigravid women recruited from maternity services in Victoria, Australia. Participants will be primigravid women, with a BMI≥30 who are less than 17 weeks gestation. Women allocated to the intervention arm will be cared for in a midwifery continuity of care model and receive an informational leaflet on managing weight gain in pregnancy. Women allocated to the control group will receive routine care in addition to the same informational leaflet. Weight gain during pregnancy, standards of care, medical and obstetric information will be extracted from medical records. Data collected at recruitment (self administered survey) and at 36 weeks by postal survey will include socio-demographic information and the use of validated scales to measure secondary outcomes. Discussion Continuity of midwifery care models are well aligned with current Victorian, Australian and many international government policies on maternity care. Increasingly, midwifery continuity models of care are being introduced in low risk maternity care, and information on their

    Extracellular matrix (ECM) remodeling dynamically occurs to accommodate adipose tissue expansion during obesity. One non-fibrillar component of ECM, biglycan, is released from the matrix in response to tissue stress; the soluble form of biglycan binds to toll-like receptor 2/4 on macrophages, causing proinflammatory cytokine secretion. To investigate the pattern and regulatory properties of biglycan expression in human adipose tissues in the context of obesity and its related diseases, we recruited 21 non-diabetic obese women, 11 type 2 diabetic obese women, and 59 normal-weight women. Regardless of the presence of diabetes, obese patients had significantly higher biglycan mRNA in both visceral and subcutaneous adipose tissue. Biglycan mRNA was noticeably higher in non-adipocytes than adipocytes and significantly decreased during adipogenesis. Adipose tissue biglycan mRNA positively correlated with adiposity indices and insulin resistance parameters; however, this relationship disappeared after adjusting for BMI. In both fat depots, biglycan mRNA strongly correlated with the expression of genes related to inflammation and endoplasmic reticulum stress. In addition, culture of human preadipocytes and differentiated adipocytes under conditions mimicking the local microenvironments of obese adipose tissues significantly increased biglycan mRNA expression. Our data indicate that biglycan gene expression is increased in obese adipose tissues by altered local conditions. PMID:27465988

    We assessed the relation of experiences of racism to the incidence of obesity and the modifying impact of residential racial segregation in the Black Women's Health Study, a follow-up study of US black women. Racism scores were created from 8 questions asked in 1997 and 2009 about the frequency of “everyday” racism (e.g., “people act as if you are dishonest”) and of “lifetime” racism (e.g., unfair treatment on the job). Residential segregation was measured by linking participant addresses to 2000 and 2010 US Census block group data on the percent of black residents. We used Cox proportional hazard models to estimate incidence rate ratios and 95% confidence intervals. Based on 4,315 incident cases of obesity identified from 1997 through 2009, both everyday racism and lifetime racism were positively associated with increased incidence. The incidence rate ratios for women who were in the highest category of everyday racism or lifetime racism in both 1997 and 2009, relative to those in the lowest category, were 1.69 (95% confidence interval: 1.45, 1.96; Ptrend < 0.01) and 1.38 (95% confidence interval: 1.15, 1.66; Ptrend < 0.01), respectively. These associations were not modified by residential segregation. These results suggest that racism contributes to the higher incidence of obesity among African American women. PMID:24585257

These associations were not modified by residential segregation. These results suggest that racism contributes to the higher incidence of obesity among African American women. PMID:24585257

    Background: Habituation is a form of learning in which repeated exposure to a stimulus leads to a decrease in responding. Eating involves repeated presentation of the same food stimulus in a meal, and habituation is reliably observed within a meal such that faster rates of habituation are associated with less energy intake. It is possible that repeated presentation of the same food over days will lead to long-term habituation, such that subjects habituate to foods repeated over meals. However, no research on long-term habituation to food in humans has been conducted. Objective: The current study was designed to assess long-term habituation in 16 obese and 16 nonobese premenopausal women. Design: Obese and nonobese women (aged 20–50 y) were randomly assigned to receive a macaroni and cheese meal presented 5 times, either daily for 1 wk or once per week for 5 wk. Results: In both obese and nonobese women, daily presentation of food resulted in faster habituation and less energy intake than did once-weekly presentation of food. Conclusions: Long-term habituation was observed when the same food was presented at daily meals but not when presented once weekly for 5 wk. These results provide the first evidence of long-term habituation to food in women and show that memory of food over daily meals can increase the rate of habituation and reduce energy intake. This trial was registered at clinicaltrials.gov as NCT01208870. PMID:21593492

    Background: The symptoms of menopause have a negative impact on quality of life, especially in women transitioning to menopause and earlier transitions. This study was conducted with the objective of assessing the effect of obesity on the severity of menopausal symptoms and the clustering of symptoms in postmenopausal women in India. Methodology: The Menopausal Rating Scale (MRS) was used to assess the severity of menopausal symptoms of postmenopausal women of Chennai, visiting Saveetha Medical College, Chennai, India. This cross-sectional study was conducted from August to November 2013 in Chennai, India. Sociodemographic characteristics, anthropometric measurements, blood pressure level, menopausal history, personal health history, and hormonal disorder issues were investigated. Results: The results have shown that 24% of the participants had complaint of mild to severe hot flushes, half of them had reported heart ailments (49%; n = 74), and disturbed sleep (48%; n = 72). The proportion of overweight/obese participants was higher in married (64%) than widows (41%), and this difference was found statistically significant (P = 0.005). There were no significant differences in MRS scores of obese and nonobese postmenopausal participants. Conclusion: There is a need of developing interactive, user friendly, technology based education module for addressing the chronic ailments of postmenopausal women. PMID:27134461

    Background A key issue in the treatment of obesity in older adults is whether the health benefits of weight loss outweigh the potential risks with respect to musculoskeletal injury. Objective To compare change in weight, improvements in metabolic risk factors, and reported musculoskeletal adverse events in middle-aged (50–59 years) and older (65–74 years), obese women. Materials and methods Participants completed an initial 6-month lifestyle intervention for weight loss, comprised of weekly group sessions, followed by 12 months of extended care with biweekly contacts. Weight and fasting blood samples were assessed at baseline, month 6, and month 18; data regarding adverse events were collected throughout the duration of the study. Results Both middle-aged (n = 162) and older (n = 56) women achieved significant weight reductions from baseline to month 6 (10.1 ± 0.68 kg and 9.3 ± 0.76 kg, respectively) and maintained a large proportion of their losses at month 18 (7.6 ± 0.87 kg and 7.6 ± 1.3 kg, respectively); there were no significant differences between the two groups with respect to weight change. Older women further experienced significant reductions in systolic blood pressure, HbA1c, and C-reactive protein from baseline to month 6 and maintained these improvements at month 18. Despite potential safety concerns, we found that older women were no more likely to experience musculoskeletal adverse events during the intervention as compared with their middle-aged counterparts. Conclusion These results suggest that older, obese women can experience significant health benefits from lifestyle treatment for obesity, including weight loss and improvements in disease risk factors. Further investigation of the impact of weight loss on additional health-related parameters and risks (eg, body composition, muscular strength, physical functioning, and injuries) in older adults is needed.

    For women attempting pregnancy, obesity reduces fertility and is an independent risk factor for obstetric and neonatal complications. The aim of this evaluator-blinded, randomized controlled trial was to evaluate a weight loss intervention on pregnancy rates in obese women undertaking fertility treatment. Forty-nine obese women, aged ≤ 37 years, presenting for fertility treatment were randomized to either a 12-week intervention (n = 27) consisting of a very-low-energy diet for the initial 6 weeks followed by a hypocaloric diet, combined with a weekly group multidisciplinary programme; or a control group (n = 22) who received recommendations for weight loss and the same printed material as the intervention. Anthropometric and reproductive parameters were measured at baseline and at 12 weeks. The 22 women who completed the intervention had greater anthropometric changes (-6.6 ± 4.6 kg and -8.7 ± 5.6 cm vs. -1.6 ± 3.6 kg and -0.6 ± 6.3 cm) compared with the control group (n = 17; P < 0.001). The intervention group achieved a pregnancy rate of 48% compared with 14% (P = 0.007), took a mean two fertility treatment cycles to achieve each pregnancy compared with four in the control group (P = 0.002), and had a marked increase in the number of live births (44% vs. 14%; P = 0.02). A group weight loss programme, incorporating dietary, exercise and behavioural components, is associated with a significant improvement in pregnancy rates and live births in a group of obese women undergoing fertility treatment.

    Introduction Obesity is one of the most common nutrition-related disorders worldwide and one of the major health problems in menopausal women, which significantly worsens the quality of life and can lead to severe diseases or even premature death. The aim of the study was to evaluate the relation between physical activity in different domains undertaken by menopausal women while performing daily activities and their body mass index (BMI). Material and methods The study was conducted on a random sample of 400 healthy Polish women aged 45-55. The questionnaire contained questions concerning the respondents’ socio-economic status, medical history and the long format of the International Physical Activity Questionnaire was used. Results Fifty-one percent (50.6%) of women had normal body mass, 43.75% of respondents were overweighed and 5.65% of women were obese. A moderate physical activity level was presented by most midlife women in domestic and garden domain, active transportation and leisure time. Pearson's correlation showed that such factors as age, education and physical activity level in different domains have a significant correlation with BMI. Conclusions Most respondents presented a moderate physical activity level in all domains except work, where the respondents had a high physical activity (PA) level. A high PA level especially at work (r = –0.5788) and during leisure time (r = –0.5175) strongly correlate with lower BMI. PMID:26327883

    Background Benign proliferative breast disease without atypia slightly increases breast cancer risk but there are currently few clinical options for breast cancer prevention in this group of women. Methods We conducted a pilot study of women with a past diagnosis of proliferative breast disease with a goal to determine if the characteristics of cells obtained by breast ductal lavage were related to nutritional factors. Results There were 57 women who enrolled. A total of 39 women yielded nipple aspirate fluid (NAF) samples and 36 underwent breast ductal lavage. Five of the lavage samples were acellular and 28 had at least 200 cells. Surprisingly, atypia was present in 11 women. Presence of atypia was associated with slight changes in morphometric features of the epithelial cells such as measures of circularity) as obtained by image analysis, but the only variable significantly different in women with atypia (versus no atypia) was a higher mean body mass index. Body mass index also was significantly correlated with C-reactive protein (CRP) levels in the nipple aspirate fluid, indicating that obesity might have a pro-inflammatory effect on the breast that can contribute to increased rates of atypia. Conclusions Although the clinical significance of atypia in breast ductal lavage is uncertain, these results support further work on prevention of obesity as a strategy for reducing breast cancer risk.

    2014-01-01

    Background Overweight and obese women have been shown to have an increased risk of recurrent miscarriage as well as other adverse reproductive outcomes, but it is yet unclear whether this is due to an effect on the endometrium, embryo or both. The current study employs proteomic analysis to examine for a potential endometrial defect in obese and overweight women with recurrent miscarriage. Methods Proteomic tissue analysis of 21 endometrial samples obtained In the midluteal phase from 16 women with recurrent miscarriage (obese, n = 12 and lean, n = 4) and 5 fertile volunteers (Obese, n = 2 and Lean, n = 3). Proteins were separated using 2-D gel electrophoresis and principle component analysis was used to quantitatively compare protein expression between groups. Protein spots showing significantly altered expression were identified using mass spectrometry. Results Obese and overweight recurrent miscarriage patients had a significantly increased endometrial expression of haptoglobin compared to their lean counterparts (p = 0.01). These patients also displayed a significant increase in endometrial expression of transthyretin (p = 0.04) and beta- globulin (p = 0.04). Principle Component Analysis (PCA) of the studied groups also demonstrated that endometrial samples could be grouped based on differences in the BMI, suggesting that obesity is an independent factor influencing endometrial protein expression. Conclusions These findings provide preliminary evidence for an alteration in the endometrial protein profile in overweight/obese women with recurrent miscarriage mainly in the form of increased haptoglobin, an inflammatory marker associated with obesity.

    We investigated the influence of SORCS1 polymorphisms on insulin secretion in obese women with PCOS. Metabolic status was recorded in 50 clinically well characterized PCOS patients. Oral glucose tolerance test was performed and laboratory parameters of insulin resistance measured. All patients were genotyped for SORCS1 rs1358030, rs1416406 and rs11192966 polymorphisms. Statistical analysis was performed using the Mann-Whitney test. SORCS1 rs1416406 significantly influenced stimulated glucose plasma levels (p = 0.006) and increased glucose stimulated insulin secretion (p = 0.034). None of the polymorphisms influenced insulin resistance as measured by homeostatic model assessment. We report for the first time the relevance of SORCS1 polymorphisms for glycemic control and glucose stimulated insulin secretion in obese women with PCOS. PMID:27052493

    The present study evaluated the impact of chronic l-citrulline (L-cit) supplementation on resting heart rate variability (HRV) and blood pressure (BP) in obese postmenopausal women. Participants were randomly assign to either an L-cit group (n=12) or a control group (n=11). HRV and BP were measured before and after 8weeks. There were significant decreases (P<0.05) in nLF (sympathetic activity), LnLF/LnHF (sympathovagal balance), and BP as well as a significant increase (P<0.05) in nHF (vagal tone) following L-cit compared with no changes after control. Our findings indicate that L-cit supplementation improves sympathovagal balance in obese postmenopausal women. PMID:27356482

    Objective Body weight and age constitute main determinants of body image in women. We analyzed the role of narcissism as a moderator of body image in young women representing various extremes of body weight. Methods The study included 325 women between 18 and 35 years, qualified into three BMI categories: obese women (BMI > 30.0, n = 72), severely underweight women who did not satisfy the remaining criteria of anorexia (BMI < 17.5, n = 85), and women with normal body weight (21.7 < “ideal BMI” > 22.7, n = 168). Satisfaction with body image was determined with Multidimensional Body-Self Relations Questionnaire and Body Esteem Scale, while narcissism was measured with Narcissistic Personality Inventory. Principal Findings We revealed that narcissism has significant impact on the body image of women who are extremely underweight or obese. Vanity and Leadership were narcissism dimensions which played significant role in slim women, as compared to Vanity and Self-Sufficiency in obese women. Conclusion The role of narcissism as a modulator of self-satisfaction with one’s body varies depending on BMI level: extremely underweight women and obese individuals constitute groups in which narcissism has the strongest impact on the self-satisfaction with body.

    2012-01-01

    Background Since obesity in urban women is prevalent in Kenya the study aimed to determine predictors of overweight and obesity in urban Kenyan women. Methods A cross-sectional study was undertaken in Nairobi Province. The province was purposively selected because it has the highest prevalence of overweight and obesity in Kenya. A total of 365 women aged 25–54 years old were randomly selected to participate in the study. Results Higher age, higher socio-economic (SE) group, increased parity, greater number of rooms in the house, and increased expenditure showed greater mean body mass index (BMI),% body fat and waist circumference (WC) at highly significant levels (p <0.001). Most of the variance in BMI was explained by age, total physical activity, percentage of fat consumed, parity and SE group in that order, together accounting for 18% of the variance in BMI. The results suggest that age was the most significant predictor of all the dependent variables appearing first in all the models, while parity was a significant predictor of BMI and WC. The upper two SE groups had significantly higher mean protein (p <0.05), cholesterol (p <0.05) and alcohol (p <0.001) intakes than the lower SE groups; while the lower SE groups had significantly higher mean fibre (p <0.001) and carbohydrate (p <0.05) intakes. A fat intake greater than 100% of the DRI dietary reference intake (DRI) had a significantly greater mean BMI (p <0.05) than a fat intake less than the DRI. Conclusions The predictors of overweight and obesity showed that urbanization and the nutrition transition were well established in the sample of women studied in the high SE groups. They exhibited a sedentary lifestyle and consumed a diet high in energy, protein, fat, cholesterol, and alcohol and lower in fibre and carbohydrate compared with those in the low SE groups.

    Mongolia is experiencing changes in its unique nomadic lifestyle and dietary habits in the last two decades with accompanying increase in obesity rate. The dietary pattern approach, which investigates the overall diet in relation to obesity risks, has become appealing in nutrition epidemiology. The aim of this study was to identify major dietary patterns of the Mongolian adults in relation to the risk of having obesity. Dietary intake of a total 418 adults aged ? 25 years was assessed by using a food frequency questionnaire with 68 items. An exploratory factor analysis resulted in three dietary patterns: transitional high in processed meat and potato, traditional rich in whole milk, fats and oils and healthy with greater intake of whole grains, mixed vegetables and fruits. Individuals in the upper quintile of the transitional pattern had significantly greater risk of obesity (BMI > or =25 kg/m2: OR=2.47; 95% CI=1.04-5.86) while subjects in the highest quintile of the healthy dietary pattern were found to have significantly decreased risk of obesity (OR: 0.49; 95% CI=0.25-0.95). Men in the highest quintile of the transitional pattern had greater risk of abdominal obesity WC > or =90 cm: OR= 4.08; 95% CI=1.11-14.97) than those in the lowest quintile. Women in the top quintile of the traditional pattern had a greater odds of having abdominal obesity (WC > or =80 cm: OR=4.59; 95% CI=1.58-13.30) than those in the lowest quintile. The study suggests that public health efforts be targeted at adults in Mongolia to address the undesirable aspects of the transitional and the traditional dietary patterns. PMID:19786392

    In 2009, the Institute of Medicine (IOM) revised their pregnancy weight gain guidelines, recommending gestational weight gain of 11-20 pounds for women with prepregnancy BMI >30 kg/m(2). We investigated the potential influence of the new guidelines on perinatal outcomes using a retrospective analysis (n = 691), comparing obese women who gained weight during pregnancy according to the new guidelines to those who gained weight according to traditional recommendations (25-35 pounds). We found no statistical difference between the two weight gain groups in infant birth weight, cesarean delivery rate, pregnancy-related hypertension, low birth weight infants, macrosomia, neonatal intensive care unit admissions, or total nursery days. Despite showing no evidence of other benefits, our data suggest that obese women who gain weight according to new IOM guidelines are no more likely to have low birth weight infants. In the absence of national consensus on appropriate gestational weight gain guidelines, our data provide useful data for clinicians when providing evidence-based weight gain goals for their obese patients.

    The prevalence of excess adiposity is increasing in less developed countries. This study explored the associations of sociodemographic factors with increased BMI among Nigeria women aged 20-49 years using secondary data collected for the 2008 NDHS. Anthropometric and socio-demographic variables of interest were extracted from the data and analyzed with SPSS version 15.0. Chi(2) was used to compare categorical variables and multi-nominal logistic regression was used to examine for correlates. The prevalence of overweight (BMI 25 to 29.9kg/m(2)) and obesity (BMI 30kg/m(2) and above) in this population were 18.1% and 7.1% respectively. The prevalence of overweight/obesity was highest among Igbo women. Multivariable logistic regression revealed increased frequency of watching television, belonging to a particular ethnic group, having a tertiary education and increased parity as risk factors for increased BMI. This study confirms a high prevalence of overweight and obesity among Nigerian women and identifies high risk groups for excessive weight gain. PMID:24558783

    Objective To examine whether obesity modify the effects of endogenous steroid sex hormones on arterial calcification in women at midlife. Methods Associations between estradiol, testosterone, sex hormone binding globulin and free androgen index and the presence and extent of coronary and aortic calcification were evaluated in 187 obese (body mass index ≥30) and 281 non-obese (body mass index <30) women from the Study of Women’s Health Across the Nation. Logistic and linear regressions were used as appropriate. Results Prevalence rates of coronary and aortic calcification were significantly higher among obese compared to non-obese (P <0.001, for both). In multivariable analyses, steroid sex hormones were not associated with presence of coronary calcification. However, for extent of coronary calcification, significant interactions were found between obesity and both sex hormone binding globulin (P<0.0001) and free androgen index (P=0.008). In non-obese women, higher sex hormone binding globulin (P=0.0006) and lower free androgen index (P=0.01) were associated with greater extent of coronary calcification while lower sex hormone binding globulin was associated with greater extent of coronary calcification in obese women (P=0.05). For aortic calcification outcomes, higher sex hormone binding globulin was associated with presence of aortic calcification among non-obese (OR:1.64, 95%CI:1.16, 2.32, for each 1-SD greater sex hormone binding globulin). Conclusions Associations between endogenous steroid sex hormones and arterial calcification vary by obesity status among perimenopausal women. Further research is needed to better understand the possible mechanisms. PMID:21471825

    Abstract Background: Obesity is a risk factor for several cancers in postmenopausal women. We attempted to determine cutoffs of adiposity measures in relation to risk of obesity-related cancers among postmenopausal women and to examine the effects of hormone therapy (HT) use on the cutoffs, neither of which has been broadly studied. Methods: We used data from the Women's Health Initiative cohort (n=144,701) and applied Cox-proportional hazards regressions to each combination of 17 cancer types and 6 anthropometric measures (weight, body mass index [BMI], weight to height ratio, waist circumference, waist to hip ratio [WHR], and waist to height ratio). Interactions between the anthropometric measures and HT use were also examined. Cutoffs were determined by applying a grid search followed by a two-fold cross validation method. Survival ROC analysis of 5- and 10-year incidence followed. Results: Breast, colorectal, colon, endometrium, kidney, and all cancers combined were significantly positively associated with all six anthropometric measures, whereas lung cancer among ever smokers was significantly inversely associated with all measures except WHR. The derived cutoffs of each obesity measure varied across cancers (e.g., BMI cutoffs for breast and endometrium cancers were 30 kg/m2 and 34 kg/m2, respectively), and also depended on HT use. The Youden indices of the cutoffs for predicting 5- and 10-year cancer incidence were higher among HT never users. Conclusion: Using a panel of different anthropometric measures, we derived optimal cut-offs categorizing populations into high- and low-risk groups, which differed by cancer type and HT use. Although the discrimination abilities of these risk categories were generally poor, the results of this study could serve as a starting point from which to determine adiposity cutoffs for inclusion in risk prediction models for specific cancer types.

    Background The increasing prevalence of obesity in pregnant women is associated with adverse maternal and neonatal outcomes, and increased costs to healthcare, the economy and broader society. Objectives To assess the efficacy of behavioural interventions for managing gestational weight gain (GWG) in the pre-conceptual and pregnancy period in overweight, obese and morbidly obese women. Search Methods A search was performed for published studies in the English language, from date? 2000–31 December 2012 in five electronic databases; PubMed, Scopus, Cochrane Library, CINAHL and PsycINFO. Selection criteria Studies were included if they compared the efficacy or effectiveness of a particular behavioural intervention in pregnant or pre-conceptual women with standard maternity care. Studies that included women with co-morbid conditions such as diabetes mellitus and polycystic ovarian syndrome were excluded to help isolate the effect of the intervention. Results Fifteen studies involving 3,426 participants were included. One study (n = 692) focused on the pre-conceptual period and the remaining 14 (n = 2,734) in the pregnancy period. Pooled mean difference for GWG indicated a lower GWG in the intervention groups when compared to standard maternity care groups (n = 1771, mean difference (MD) −1.66 kg, 95% CI −3.12 to −0.21 kg). With respect to the types of participants, considerable heterogeneity between studies was shown in the obese subgroup [Tau2 = 15.61; Chi2 = 40.80, df = 3 (P<0.00001); I2 = 93%]. Conclusions Behavioural interventions in pregnancy may be effective in reducing GWG in obese women without comorbid conditions, but not overweight or morbidly obese women. Behavioural interventions had no effect on postpartum weight loss or retention, gestation week of delivery and infant birth weight in overweight, obese and morbidly obese women. PMID:24827704

    Background and Aims Upper-body, i.e. visceral, obesity is associated with insulin resistance and impaired protein synthesis. It is unclear whether postprandial stimulation of protein synthesis is affected by body fat distribution. We investigated the postprandial protein anabolic response in a cohort of obese women. Methods Participants were studied after an overnight fast and after a mixed meal, grouped as upper-body obese (UBO, waist-to-hip ratio, WHR, >0.85, n=6) vs. lower-body obese (LBO, WHR<0.80, n=7). Lipid and carbohydrate metabolism were assessed by measurements of plasma free fatty acids (FFA), insulin and glucose concentrations, and calculation of the Quicki index from fasting glucose and insulin values. Different labels of stable isotopes of phenylalanine were administered intravenously and orally, and leg and whole-body protein breakdown and synthesis were calculated from phenylalanine/tyrosine isotopic enrichments in femoral arterial and venous blood, using equations for steady-state kinetics. Data are denoted as mean±SD. Results Age (38 vs. 40, p=0.549) and body-mass index (33.7±1.9 vs. 35.0±1.8, p=0.241) were similar in both groups. UBO subjects had more visceral fat (p=0.002) and higher fat-free body mass (FFM) (p=0.015). Plasma insulin concentrations were greater in UBO than LBO women (p=0.013), and UBO were less insulin sensitive (Quicki=0.32±0.01 vs. 0.36±0.02, p=0.005). Protein kinetics across the leg were not different between groups. Fasting whole body protein balance was similarly negative in both groups (UBO −6.5±2.4 vs. LBO −7.6±0.9 μmol/kgFFM/h, p=1.0). Postprandially, whole body protein balance became less positive in UBO than in LBO (14.8±3.7 vs. 20.2±3.7 μmol/kgFFM/h, p=0.017). Conclusions Whole-body protein balance following a meal is less positive in upper-body obese, insulin-resistant, women than in lower-body obese women. PMID:24269078

Estrogens are synthesized from androgens by aromatase in the gonads and in peripheral tissues, principally, adipose tissue. Obesity in women, regardless of their age, leads to more aromatase and more extra-glandular estrogen production. In postmenopausal women, in whom ovarian estrogen production is absent, the increased incidence of breast cancer in women with high body mass index has been attributed to the relatively high plasma levels of estradiol from subcutaneous fat. In contrast, obesity in premenopausal women is associated with a previously unexplained reduced incidence of breast cancer. In obese premenopausal women, the cumulative effect of higher levels of estrogens synthesized in the peripheral tissues, together with ovarian estrogen production, results in a negative feedback on the hypothalamic pituitary controlled release of gonadotrophins and a resultant diminution in ovarian steroid production. As a consequence, the normal balance of estrogen and progesterone levels is disrupted: while estrogen levels are normalized, progesterone production is markedly decreased. Progesterone is a promoter of proliferation in the breast. The low levels of progesterone in obese premenopausal women are consistent with, and we propose, are responsible for, the reduction in breast cancer incidence in these women. PMID:25414027

    The higher rate of obesity among low-income women has widely been attributed to environmental barriers; however, many low-income women are still able to maintain a healthy weight despite obesogenic environments. To better understand personal and behavioral attributes related to food choice and weight, overweight/obese women and lean/normal weight women living in similar low-income environments, participated in focus groups, and taste testing sessions to investigate food liking (n=83). During focus groups, lean/normal weight participants reported that health was influential in food choice, while overweight/obese participants expressed cost as being more of a factor. Both BMI (kg/m(2)) groups reported that taste was of greatest importance. Personal factors, like emotional eating, and overeating were also discussed with differences noted between BMI (kg/m(2)) groups. Quantitative data also showed cost to be more important for overweight/obese women. Taste testing results revealed that overweight/obese participants had a higher overall liking for both healthy and less healthy foods, as well as other food categories. Additionally, these women had a higher liking of fat in the context of spreadable fats. Our results show that a variety of complex factors interact to influence eating behavior and present weight status of women living in similarly impoverished environments. However, findings from this exploratory study should be confirmed through further research. PMID:23428940

    Although there is growing evidence that higher adiposity increases ovarian cancer risk, little is known about its impact in African American (AA) women, the racial/ethnic group with the highest prevalence of obesity. We evaluated the impact of body mass index (BMI) 1 year before diagnosis and weight gain since age 18 years on ovarian cancer risk in a population-based case-control study in AA women in 11 geographical areas in the US. Cases (n = 492) and age and site matched controls (n = 696) were identified through rapid case ascertainment and random-digit-dialing, respectively. Information was collected on demographic and lifestyle factors, including self-reported height, weight at age 18 and weight 1 year before diagnosis/interview. Multivariable logistic regression was used to compute odds ratios (OR) and 95% confidence intervals (CI), adjusting for potential covariates. Obese women had elevated ovarian cancer risk, particularly for BMI ≥ 40 kg/m(2) compared to BMI <25 (OR = 1.72, 95% CI: 1.12-2.66; p for trend: 0.03). There was also a strong association with weight gain since age 18 (OR: 1.52; 95% CI: 1.07-2.16; p for trend: 0.02) comparing the highest to lowest quartile. In stratified analyses by menopausal status, the association with BMI and weight gain was limited to postmenopausal women, with a 15% (95% CI: 1.05-1.23) increase in risk per 5 kg/m(2) of BMI and 6% (95% CI: 1.01-1.10) increase in risk per 5 kg of weight gain. Excluding hormone therapy users essentially did not change results. Obesity and excessive adult weight gain may increase ovarian cancer risk in post-menopausal AA women. PMID:27038123

    Worldwide, the prevalence of obesity has reached epidemic proportions. In Denmark one third of all pregnant women are overweight and 12 % are obese. Perhaps even more concerning, a dramatic rise in the prevalence of childhood overweight and obesity has also been evident over recent decades. The obesity epidemic is not simply a consequence of poor diet or sedentary lifestyles. Obesity is a multifactorial condition in which environmental, biological and genetic factors all play essential roles. The Developmental Origins of Health and Disease (DoHaD) hypothesis has highlighted the link between prenatal, perinatal and early postnatal exposure to certain environmental factors and subsequent development of obesity and non-communicable diseases. Maternal obesity and excessive gestational weight gain, resulting in over-nutrition of the fetus, are major contributors to obesity and metabolic disturbances in the offspring. Pregnancy offers the opportunity to modify the intrauterine environment, and maternal lifestyle changes during gestation may confer health benefits to the child. The overall aim with this PhD thesis was to study the effects of maternal obesity on offspring body size and metabolic outcomes, with special emphasis on the effects of lifestyle intervention during pregnancy. The thesis is based on a literature review, description of own studies and three original papers/manuscripts (I, II and III). In paper I, we used data from the Danish Medical Birth Registry. The aim of this paper was to examine the impact of maternal pregestational Body Mass Index (BMI) and smoking on neonatal abdominal circumference (AC) and weight at birth and to define reference curves for birth AC and weight in offspring of healthy, non-smoking, normal weight women. Data on 366,886 singletons were extracted and analyzed using multivariate linear regressions. We found that birth AC and weight increased with increasing pregestational BMI and decreased with smoking. Reference curves were

    Objective To assess whether obesity is an independent predictor of mortality in women with cervical cancer. Methods This retrospective cohort study of patients with stages IB1-IVA cervical cancer treated with curative intent at MD Anderson Cancer Center from 1980 through 2007 categorized these women as underweight, normal weight, overweight, obese, or morbidly obese according to National Institutes of Health definitions. In addition to weight category, known prognostic factors for survival after a diagnosis of cervical cancer were included in a multivariate model. These known prognostic factors included age, smoking status, race or ethnicity (self-reported), socioeconomic status, comorbidities, tumor histologic subtype, tumor stage, tumor size, presence or absence of hydronephrosis, radiologic evidence of nodal metastasis, and the addition of concurrent chemotherapy with definitive radiation. Results A total of 3,086 patients met the inclusion criteria. The median survival for the entire cohort was 81 months (range, 0–365). The presence of lymph node spread and advancing stage were the most significant predictors of survival. Compared to normal-weight women, morbidly obese women had a significantly higher hazard ratio for both all-cause death (hazard ratio, 1.26; 95% CI, 1.10–1.45) and disease-specific death (hazard ratio, 1.24; 95% CI, 1.06–1.47). Underweight, overweight, and obese women did not have an increased risk for death compared to normal-weight women. Conclusions After controlling for all previously known prognostic factors, morbid obesity remains an independent risk factor for death from cervical cancer. Overweight and obese women have the same prognosis as normal-weight women. PMID:25415160

    Polycystic ovary syndrome (PCOS) is the most common cause for androgen excess in women. It is associated with wide variety of metabolic disorders. The present study assessed morning plasma cortisol in women with PCOS. One hundred and ninety seven cases and 55 controls were enrolled for this study. The mean age of patients and controls were 23 ± 5.6 years and 25 ± 4.3 years. One hundred twelve (56%) women with PCOS had BMI >25. Serum cortisol levels were significantly higher in lean PCOS women compared to controls (13.4 ± 5.1 versus 11.3 ± 4.5, p < 0.01) and over-weight PCOS women group (13.4 ± 5.1 versus 9.3 ± 3.2, p < 0.01). There was a trend for less acne and hirsutism with increase in BMI. Morning plasma cortisol was lower among obese women with PCOS. Morning plasma cortisol correlated negatively with BMI in PCOS women with normal glucose tolerance. PMID:23957781

    Increasing evidence suggests the association between obesity and bone metabolism. However, whether excessive fat accumulation has a beneficial or adverse effect on bone health remains controversial. Chemerin is a novel adipocyte-derived hormone and a chemoattractant cytokine that regulates adipogenesis. This study was performed to investigate the associations of serum chemerin with bone mineral density (BMD) and serum pro-inflammatory cytokine levels in 543 Chinese obese postmenopausal women. BMD of the femoral neck and lumbar spine, lean mass, and fat mass were measured using dual energy X-ray absorptiometry. Anthropometric assessment and laboratory measurements were performed. The age, time after menopause, and fat mass were negatively correlated with femoral and lumbar BMD, whereas lean mass was positively correlated with aforementioned variables. Furthermore, BMD at the lumbar spine was inversely associated with serum chemerin and TNF-α levels (r = -0.155, P = 0.001; r = -0.147, P = 0.001). Multiple linear regression analyses showed that serum chemerin levels were negatively correlated with BMD at the lumbar site after controlling for the age, lean, and fat mass (β = -0.125, P = 0.001). Chronic low-grade inflammation state in obese population has an inverse effect on bone mass. Chemerin as an adipocytokine and chemoattractant negatively affects the bone mass of Chinese obese postmenopausal women. Further studies are needed to confirm the potential role of chemerin in the crosstalk between bone and fat accumulation in obese population. PMID:27583869

    Breastfeeding has been found to have a protective effect on subsequent development of obesity in childhood, particularly in white, non-Hispanic populations. The protective effect of nursing for more than 12 months in children of Latina women is less clear, which may be due to differences in levels of acculturation in previously studied populations. We evaluated the association between breastfeeding for 12 months or more and risk for obesity in a cohort of children of recently immigrated relatively unacculturated Latina mothers. Maternal characteristics at birth, including length of stay in the United States, breastfeeding habits at 4-6 weeks of age, 6 months, and 1 year, and anthropometric measurements were obtained for a cohort of 196 children participating in a prospective study. At 1 year of age 39.0% of infants were being breastfed. Being breastfed at 1 year of age was associated with a decreased risk of obesity in both univariate (odds ratio (OR) 0.49, 95% confidence interval (CI) 0.21-0.83) and multivariate models (OR 0.39, 95% CI 0.02-0.93) adjusting for maternal BMI, marital status, education level, country of origin, age, years of living in the United States, and child's birth weight at 3 years of age, regardless of mother's acculturation status using length of stay in the United States as a proxy for acculturation. The association with breastfeeding persisted at 4 years of age as a protective factor for obesity (OR 0.29, 95% CI 0.11-0.80). Breastfeeding for longer than 12 months provides a significant protective effect on the development of obesity in early childhood in a cohort of children of high-risk recently immigrated Latina women in San Francisco who were relatively unacculturated to the United States.

    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. PMID:25068676

    Non-obese individuals limit energy intake and maintain weight long-term. Knowledge of the mechanism they use to accomplish this could help in weight maintenance after weight loss and prevention of unneeded weight gain. The objective of the present study was to determine whether non-obese women use orosensory cues to limit short-term intake of high-energy density foods. Forty non-obese women consumed two high-energy rice puddings of equal energy density, one with high sugar and one with high fat. There were four study conditions. Participants ate until satisfied (basal), satisfied based on taste (taste), satisfied based on fullness (fullness) and while watching television (distraction). The participants were asked to refrain from eating and drinking after 2200. The treatments were done between 0830 and 0900. The order of treatments was randomized and all subjects completed all treatments. The quantity consumed and variation in hunger and taste intensity were the primary measures. Results were subjected to within subjects analysis of variance (ANOVA). Intake was significantly greater in the high-fat groups than in the high-carbohydrate groups (P = 0.0001). Study condition had a significant effect on intake (P = 0.0000) with the taste condition generally resulting in the lowest intake. Hunger intensity significantly decreased after meal intake (P = 0.0156). There was a significant effect of condition (P = 0.0001) with base and taste conditions showing the greatest decrease. In the taste condition, specifically, the intensity of taste and hunger declined after intake (P = 0.0000). These results indicate that taste satisfaction can limit meal intake in non-obese women. Taste satisfaction could be a mechanism that is used to reduce food intake to compensate for previous excess consumption. PMID:19178789

    Obesity is a chronic disease with a multifaceted treatment approach that includes nutritional counseling, structured exercise training, and increased daily physical activity. Increased body mass elicits higher cardiovascular, ventilatory and metabolic demands to varying degrees during exercise. With functional capacity assessment, this variability can be evaluated so individualized guidance for exercise training and daily physical activity can be provided. The aim of the present study was to compare cardiovascular, ventilatory and metabolic responses obtained during a symptom-limited cardiopulmonary exercise test (CPX) on a treadmill to responses obtained by the incremental shuttle walk test (ISWT) in obese women and to propose a peak oxygen consumption (VO2) prediction equation through variables obtained during the ISWT. Forty obese women (BMI ≥30 kg/m2) performed one treadmill CPX and two ISWTs. Heart rate (HR), arterial blood pressure (ABP) and perceived exertion by the Borg scale were measured at rest, during each stage of the exercise protocol, and throughout the recovery period. The predicted maximal heart rate (HRmax) was calculated (210 – age in years) (16) and compared to the HR response during the CPX. Peak VO2 obtained during CPX correlated significantly (P<0.05) with ISWT peak VO2 (r=0.79) as well as ISWT distance (r=0.65). The predictive model for CPX peak VO2, using age and ISWT distance explained 67% of the variability. The current study indicates the ISWT may be used to predict aerobic capacity in obese women when CPX is not a viable option. PMID:27409333

    PubMed Central

    2011-01-01

    Background Vaspin and omentin are recently described molecules that belong to the adipokine family and seem to be related to metabolic risk factors. The objectives of this study were twofold: to evaluate vaspin and omentin circulating levels and mRNA expression in subcutaneous and visceral adipose tissues in non-diabetic morbidly obese women; and to assess the relationship of vaspin and omentin with anthropometric and metabolic parameters, and other adipo/cytokines. Design We analysed vaspin and omentin circulating levels in 71 women of European descent (40 morbidly obese [BMI ≥ 40 kg/m2] and 31 lean [BMI ≤ 25]). We assessed vaspin and omentin gene expression in paired samples of visceral and subcutaneous abdominal adipose tissue from 46 women: 40 morbidly obese and 6 lean. We determined serum vaspin and plasma omentin levels with an Enzyme-Linked Immunosorbent Assay and adipose tissue mRNA expression by real time RT-PCR. Results Serum vaspin levels in the morbidly obese were not significantly different from those in controls. They correlated inversely with levels of lipocalin 2 and interleukin 6. Vaspin mRNA expression was significantly higher in the morbidly obese, in both subcutaneous and visceral adipose tissue. Plasma omentin levels were significantly lower in the morbidly obese and they correlated inversely with glucidic metabolism parameters. Omentin circulating levels, then, correlated inversely with the metabolic syndrome (MS). Omentin expression in visceral adipose tissue was significantly lower in morbidly obese women than in controls. Conclusions The present study indicates that vaspin may have a compensatory role in the underlying inflammation of obesity. Decreased omentin circulating levels have a close association with MS in morbidly obese women. PMID:21526992

    In polycystic ovary syndrome (PCOS), cardiovascular risk is increased. Peak O2 uptake (V˙O2peak) predicts the cardiovascular risk. We were the first to examine the contribution of systemic O2 delivery and arteriovenous O2 difference to V˙O2peak in overweight and obese women with PCOS. Fifteen overweight or obese PCOS women and 15 age-, anthropometry-, and physical activity-matched control women performed a maximal incremental cycling exercise test. Alveolar gas exchange (volume turbine and mass spectrometry), arterial O2 saturation (pulse oximetry), and cardiac output (CO) (impedance cardiography) were monitored. Hb concentration was determined. Arterial O2 content and arteriovenous O2 difference (C(a-v)O2) (Fick equation) were calculated. Insulin resistance was evaluated by homeostasis model assessment (HOMA-IR). PCOS women had lower V˙O2peak than controls (40 ± 6 vs. 46 ± 5 mL/min/kg fat-free mass [FFM], P = 0.011). Arterial O2 content was similarly maintained in the groups throughout the exercise test (P > 0.05). Linear regression analysis revealed a pronounced response of CO to increasing V˙O2 in PCOS women during the exercise test: A ∆CO/∆V˙O2 slope was steeper in PCOS women than in controls (β = 5.84 vs. β = 5.21, P = 0.004). Eventually, the groups attained similar peak CO and peak CO scaled to FFM (P > 0.05). Instead, C(a-v)O2 at peak exercise was lower in PCOS women than in controls (13.2 ± 1.6 vs. 14.8 ± 2.4 mL O2/100 mL blood, P = 0.044). HOMA-IR was similar in the groups (P > 0.05). The altered cardiorespiratory responses to exercise in overweight and obese PCOS women indicate that PCOS per se is associated with alterations in peripheral adjustments to exercise rather than with limitations of systemic O2 delivery.

    Our aim was to evaluate the influence of the Gln27Glu polymorphism of the β2-adrenergic receptor (ADRβ2) gene, fat intake and physical activity on the energy expenditure (EE) and nutritional status of obese women. Sixty obese women (30-46 years) participated in the study and were assigned to three groups depending on the genotypes: Gln27Gln, Gln27Glu and Glu27Glu. At baseline and after nutritional intervention, the anthropometric and body composition (bioelectrical impedance), dietary, EE (indirect calorimetry) and biochemical variables were measured. All women received a high-fat test meal to determine the postprandial EE (short-term) and an energy-restricted diet for 10 weeks (long term). The frequencies of Gln27Gln, Gln27Glu and Glu27Glu were 36.67, 40.0 and 23.33 %, respectively. Anthropometric and biochemical variables and EE did not differ between groups, although women who had no polymorphism demonstrated decreased carbohydrate oxidation. On the other hand, the Glu27Glu genotype showed a positive relation with EE in physical activity and fat oxidation. The environmental factors and Gln27Glu polymorphism did not influence the nutritional status and EE of obese women, but physical activity in obese women with the polymorphism in the ADRβ2 gene can promote fat oxidation. The results suggest that encouraging the practice of physical exercise is important considering the high frequency of this polymorphism in obese subjects. PMID:25893811

    The adipokines produced from adipose tissues influence energy homeostasis, resulting in alterations of the adipokine concentrations. This process may be associated with fertility impairment, resulting in recurrent miscarriage. The present study investigated whether there was any association between the UCP2 45-bp indel polymorphism and the adipokine gene polymorphisms, namely leptin 2549 (C/A), adeponectin 276 (G/T) and 45 (T/G) and resistin 420 (C/G) in 200 non-obese recurrent miscarriage patients and 300 ethnically matched negative controls. These markers were studied using gene-specific PCR single specific primer and restriction fragment length polymorphism. For leptin 2549 and adeponectin 276, the A allele and G allele showed 3.42-fold (P=0.0001) and 1.36-fold (P=0.036) increased risk of recurrent miscarriage, respectively. Combined analysis of UCP2 45-bp indel and leptin 2549 showed U0-L0 and U1-L0 variants to be at 2- and 3-fold increased associative risk, respectively. Combined analysis of leptin 2549 and adeponectin 276 showed L0-D0 and L0-D1 variants to be at 2- and 4-fold increased associative risk, respectively. The combination U1-L0-D1-A1-R1 was 4.39-fold higher (P=0.0007) among recurrent miscarriage patients. In conclusion, the results highlight the role of the studied adipokine and UCP2 polymorphisms in recurrent miscarriage among the North Indian non-obese population. Pregnancy invokes a large shift in maternal metabolism. The normal concentrations of adipokines, which maintain the integrity of the hypothalamus-pituitary-gonadal axis, regular ovulatory processes and successful embryo implantation, are altered because of the influence of energy homeostasis, which in turn leads to fertility impairment and recurrent miscarriage of unknown aetiology. Recurrent miscarriage is reported in higher frequency among obese women.

    Background/Objectives: Neuroimaging studies in obese subjects have identified abnormal activation of key regions of central reward circuits, including the nucleus accumbens (NAcc), in response to food-related stimuli. We aimed to examine whether women with elevated body mass index (BMI) show structural and resting state (RS) functional connectivity alterations within regions of the reward network. Subjects/Methods: Fifty healthy, premenopausal women, 19 overweight and obese (high BMI=26–38 kg m−2) and 31 lean (BMI=19–25 kg m−2) were selected from the University of California Los Angeles' Oppenheimer Center for Neurobiology of Stress database. Structural and RS functional scans were collected. Group differences in grey matter volume (GMV) of the NAcc, oscillation dynamics of intrinsic brain activity and functional connectivity of the NAcc to regions within the reward network were examined. Results: GMV of the left NAcc was significantly greater in the high BMI group than in the lean group (P=0.031). Altered frequency distributions were observed in women with high BMI compared with lean group in the left NAcc (P=0.009) in a medium-frequency (MF) band, and in bilateral anterior cingulate cortex (ACC) (P=0.014, <0.001) and ventro-medial prefrontal cortex (vmPFC) (P=0.034, <0.001) in a high-frequency band. Subjects with high BMI had greater connectivity of the left NAcc with bilateral ACC (P=0.024) and right vmPFC (P=0.032) in a MF band and with the left ACC (P=0.03) in a high frequency band. Conclusions: Overweight and obese women in the absence of food-related stimuli show significant structural and functional alterations within regions of reward-related brain networks, which may have a role in altered ingestive behaviors.

    OBJECTIVE: The aim of this study was to evaluate the multisegmental static postural balance of active eutrophic and obese elderly women using a three-dimensional system under different sensory conditions. METHODS: A cross-sectional study was conducted on 31 elderly women (16 eutrophic and 15 obese) aged 65 to 75 years. The following anthropometric measurements were obtained: weight, height, waist and hip circumference, and handgrip strength. The physical activity level was evaluated using the International Physical Activity Questionnaire. Body composition was measured using the deuterium oxide dilution technique. The Polhemus® Patriot (three-dimensional) equipment was used to measure the parameters of postural balance along the anteroposterior and laterolateral axes. The data acquisition involved one trial of 60 s to test the limit of stability and four trials of 90 s each under the following conditions: (1) eyes open, stable surface; (2) eyes closed, stable surface; (3) eyes open, unstable surface; and (4) eyes closed, unstable surface. RESULTS: For the limit of stability, significant differences were observed in the maximum anteroposterior and laterolateral displacement (p<0.01) and in the parameter maximum anteroposterior displacement in the eyes closed stable surface condition (p<0.01) and maximum anteroposterior and laterolateral displacement in the eyes open unstable surface (p<0.01 and p = 0.03) and eyes closed unstable surface (p<0.01 and p<0.01) conditions. CONCLUSIONS: Obese elderly women exhibited a lower stability limit (lower sway area) compared with eutrophic women, leaving them more vulnerable to falls. PMID:22666792

    Dyspnea on exertion (DOE) is a common symptom in obesity. We investigated whether aerobic exercise training without weight loss could reduce DOE. Twenty-two otherwise healthy obese women participated in a 12-week supervised aerobic exercise training program, exercising 30 min/day at 70-80% heart rate reserve, 4 days/week. Subjects were grouped based on their Ratings of Perceived Breathlessness (RPB) during constant load 60 W cycling: +DOE (n=12, RPB≥4, 37±7 years, 34±4 kg/m(2)) and -DOE (n=10, RPB≤2, 32±6 years, 33±3 kg/m(2)). No significant differences between the groups in body composition, pulmonary function, or cardiorespiratory fitness were observed pre-training. Post-training,peak was improved significantly in both groups (+DOE: 12±7, -DOE: 14±8%). RPB was significantly decreased in the +DOE (4.7±1.0-2.5±1.0) and remained low in the -DOE group (1.2±0.6-1.3±1.0) (interaction p<0.001). The reduction in RPB was not significantly correlated with the improvement in cardiorespiratory fitness. Aerobic exercise training improved cardiorespiratory fitness and DOE and thus appears to be an effective treatment for DOE in obese women. PMID:26593640

    Background The soluble cell adhesion molecules and adipokines are elevated in patients with obesity, hypertension, type 2 diabetes mellitus, breast cancer and atherosclerosis. Objective To investigate the relationship between anthropometric profile, dietary intake, lipid profile and fasting glycemia with serum levels of adipokines (adiponectin and PAI-1) and adhesion molecules (ICAM-1 and VCAM-1) in women without breast cancer undergoing routine mammographic screening. Design Transversal study. Subjects One hundred and forty-five women over 40-years old participated in this study. Results In 39.3% of cases the BMI was above 30 kg/m2; 46.9% had hypertension, 14.5% had type 2 Diabetes Mellitus, 31.7% had dyslipidemia and 88.3% presented a waist-to-hip ratio ≥ 0.8. A linear correlation was found between serum levels of PAI-1 and triglycerides, between serum levels of PAI-1 and WHR and between serum levels of VCAM-1 and BMI. Conclusion We found a high prevalence of obesity and metabolic syndrome. PAI-1 and VCAM-1 levels were correlated with clinical indicators of obesity and overweight. PMID:23113882

    The effects of variation in odors and thickening agents on sensory properties and acceptability of a model custard dessert were investigated in normal weight and obese women. Subjects rated their liking and the intensity of sensory properties (sweetness, vanilla and butter flavors, and creaminess) of 3 block samples (the first varied in vanilla aroma, the second varied in butter aroma and the third varied in xanthan gum). Significant differences were found in acceptability and intensity ratings in relation to body mass index. The addition of butter aroma in the custard was the most effective way to elicit odor-taste, odor-flavor and odor-texture interactions in obese women. In this group, butter aroma, signaling energy dense products, increased the perception of sweetness, vanilla flavor and creaminess, which are all desirable properties in a custard, while maintaining a high liking degree. Understanding cross-modal interactions in relation to nutritional status is interesting in order to develop new food products with reduced sugar and fat, that are still satisfying for the consumer. This could have important implications to reduce caloric intake and tackle the obesity epidemic. PMID:26911260

    The global obesity epidemic continues unabated, now rapidly expanding to developing countries. Multiple comorbidities and premature mortality are associated with obesity, most frequently diabetes. The associated financial and economical burden is escalating as well. The sedentary lifestyle adopted by many pregnant women because of traditional practices and the current recommendation for gestational weight gain are contributing factors to the obesity and diabetes epidemic. Physical inactivity is recognized as an independent risk factor for obesity insulin resistance and type 2 diabetes; the physiological and hormonal changes associated with pregnancy magnify this risk. Conversely, evidence and accumulated experience indicate that antenatal lifestyle interventions that include physical activity and judicious dieting could improve the pregnancy outcome and reduce the risk of gestational diabetes and is effective as an adjunctive therapy for diabetes in pregnancy. All major professional organizations, among them American Congress of Obstetricians and Gynecologists (ACOG), American Diabetes Association (ADA), Royal College of Obstetricians and Gynaecologists (RCOG), and Society of Obstetricians and Gynaecologists of Canada (SOGC), recommend lifestyle interventions that include diet and exercise to prevent or manage gestational diabetes or diabetes mellitus.

    Background Metabolic syndrome (MetS) is an important health problem which puts individuals at risk for cardiovascular diseases and type 2 diabetes as well as obesity-related cancers such as colon and renal cell in men, and endometrial and oesophageal in women. Objective This study was aimed at examining how obesity indicators and related determinants influence metabolic syndrome, and how the factors can be used to predict the syndrome and its cut-offs in postmenopausal Ghanaian women. Methods Two hundred and fifty (250) Ghanaian subjects were involved in the study with one hundred and forty-three (143) being premenopausal women and one hundred and seven (107) postmenopausal women. The influence of traditional metabolic risk factors including high blood pressure, dyslipidemia and glucose intolerance on obesity and atherogenic indices i.e. body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), Waist-to-thigh ratio (WTR), waist-to-height ratio (WHtR), high density lipoprotein cholesterol to total cholesterol ratio (HDL-C/TC), high density lipoprotein cholesterol to low density lipoprotein ratio (HDL-C/LDL-C) and triglyceride to high density lipoprotein cholesterol ratio (TG/HDL-C) were identified according to the Harmonization (H_MS) criterion. Results The predominant anthropometric marker that significantly influence metabolic risk factors among the pre- and postmenopausal women was waist-to-hip ratio (premenopausal: p- 0.004, 0.026 and 0.002 for systolic blood pressure (SBP), fasting blood glucose (FBG) and HDL-C; postmenopausal: p-0.012, 0.048, 0.007 and 0.0061 for diastolic blood pressure (DBP), FBG, triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) respectively). Using the receiver operating characteristic (ROC) analysis, the area under the curve for WC, WHR, TG/HDL-C and HDL-C/TC among postmenopausal women were estimated at 0.6, 0.6, 0.8 and 0.8 respectively. The appropriate cut-off values for WC, WHR, TG/HDL-C and HDL

    Purpose The primary purpose of this study was to compare maternal plasma inflammation between physically active and inactive obese women during late pregnancy. The secondary purpose was to examine the relationships between maternal plasma inflammation and lipid metabolism and maternal and neonatal metabolic health in these women. Methods A cross-sectional, observational study design was performed in 16 obese-inactive ((OBI) age: 25.0 ± 4.8 years, pre-pregnancy BMI: 36.3 ± 4.3kg/m2, body fat percentage in late gestation: 37.7 ± 3.5%) and 16 obese-active ((OBA) age: 28.9 ± 4.8 years, pre-pregnancy BMI: 34.0±3.7kg/m2, body fat in late gestation: 36.6 ± 3.8%) women during the third trimester of pregnancy. Maternal plasma inflammation (C -reactive protein (CRP)) and insulin resistance (Homeostatic Model Assessment-Insulin Resistance (HOMA-IR)) were measured at rest. Plasma lipid concentration and metabolism (lipid oxidation and lipolysis) were measured at rest, during a 30-minute bout of low-intensity (40% VO2peak) exercise, and during a resting recovery period using indirect calorimetry. Umbilical cord blood was collected for measurement of neonatal plasma insulin resistance, inflammation, and lipid concentration. Neonatal body composition was measured via air displacement plethysmography. Results Maternal plasma CRP concentration was significantly higher in OBI compared to OBA women (9.1 ± 4.0 mg/L versus 6.3 ±2.5mg/L, p=0.02). Maternal plasma CRP concentration was significantly associated with maternal lipolysis (r=0.43, p=0.02), baseline lipid oxidation rate (r=0.39, p=0.03), and baseline plasma free fatty acid concentration (r=0.36, p=0.04). Conclusions Maternal physical activity may reduce inflammation during pregnancy in obese women. Maternal lipid metabolism is related to systemic inflammation. PMID:26799789

    Obesity and osteoporosis are chronic disorders with increasing prevalence worldwide. The aim of this study was to investigate the association between obesity and fracture in postmenopausal women from Santa Maria, Brazil. A cross-sectional study was carried out at Santa Maria (parallel 29° south), Brazil. Postmenopausal women aged ≥55 yr who had at least 1 appointment at the primary care in the 2 years before the study were recruited from March 1, 2013 to August 31, 2013. The Global Longitudinal Study of Osteoporosis in Women study questionnaire was applied with permission of The Center for Outcomes Research, University of Massachusetts Medical School. Height and weight were measured according to the World Health Organization protocol. Bone fractures (excluding hand, feet, and head) that occurred after the age of 45 yr were considered as the outcome. Overall, 1057 women completed the study, of whom 984 had body mass index measured. The mean (standard deviation) age and body mass index of the women included in the study were 67.1 (7.6) yr and 29.2 (5.5) kg/m(2), respectively. The prevalence of fractures in obese and nonobese women was similar (17.3% vs 16.0%); 41.4% of all fractures occurred in obese women. Obese postmenopausal women make a substantial contribution to the overall burden of prevalent fractures in this population. Our results provide further evidence in support of the concept that obesity is not protective against fracture. PMID:25534276

    Abstract Background Sarcopenic obese (SO) individuals are a unique subset of subjects that combines obesity and sarcopenia. Traditional weight loss programmes including aerobic exercises may worsen their condition by further reducing their lean mass. The objective of this observational and retrospective study was to verify the effect of a mixed weight loss programme combining caloric restriction and exercise on body composition, and lipid‐lipoprotein profile of obese women according to their sarcopenic status. Methods One hundred and forty‐six obese women (body mass index ≥ 30 kg/m2 and fat mass ≥ 40%) participated to the 3 week usual and institutionalized weight‐reducing programme combining a dietary plan (1400 ± 200 kcal/day) and aerobic exercise (1 h/day, 6 days/week) of a specialized medical institution. The lean body mass index (LMI; lean mass/height2) was calculated, and women in the lowest tertile of LMI were considered SO. Results At baseline, SO women were older, and their body weight and LMI were lower than non‐sarcopenic obese (N‐SO) women (p < 0.05). N‐SO and SO women similarly lost fat mass and improved their lipid‐lipoprotein profile (p < 0.05), while differences in LMI between groups persisted at the end of the weight‐reducing programme. Indeed, N‐SO women lost lean mass (p < 0.05) while SO did not. Conclusions These findings suggest that a short weight loss programme combining caloric restriction and aerobic exercise may significantly reduce fat mass and improve lipid‐lipoprotein profile in obese women, independently of their sarcopenic status. Such programmes may have deleterious effects on lean mass in N‐SO subjects, only. PMID:27247859

    Accurate methods for assessing body composition in subjects with obesity and anorexia nervosa (AN) are important for determination of metabolic and cardiovascular risk factors and to monitor therapeutic interventions. The purpose of our study was to assess the accuracy of dual-energy X-ray absorptiometry (DXA) for measuring abdominal and thigh fat, and thigh muscle mass in premenopausal women with obesity, AN, and normal weight compared to computed tomography (CT). In addition, we wanted to assess the impact of hydration on DXA-derived measures of body composition by using bioelectrical impedance analysis (BIA). We studied a total of 91 premenopausal women (34 obese, 39 with AN, and 18 lean controls). Our results demonstrate strong correlations between DXA- and CT-derived body composition measurements in AN, obese, and lean controls (r = 0.77-0.95, P < 0.0001). After controlling for total body water (TBW), the correlation coefficients were comparable. DXA trunk fat correlated with CT visceral fat (r = 0.51-0.70, P < 0.0001). DXA underestimated trunk and thigh fat and overestimated thigh muscle mass and this error increased with increasing weight. Our study showed that DXA is a useful method for assessing body composition in premenopausal women within the phenotypic spectrum ranging from obesity to AN. However, it is important to recognize that DXA may not accurately assess body composition in markedly obese women. The level of hydration does not significantly affect most DXA body composition measurements, with the exceptions of thigh fat. PMID:20111013

    Overweight and obesity are associated with increased postmenopausal breast cancer risk; however, it is unclear whether losing excess weight will lower risk. Therefore, we examined the relationship between weight loss and postmenopausal breast cancer among 13,055 overweight and obese, cancer-free women who enrolled in the Cancer Prevention Study-II (CPS-II) Nutrition Cohort in 1992. During the 15 year follow-up, 816 postmenopausal breast cancer cases were diagnosed. Self-reported weight was collected before diagnosis at baseline and 10 years prior to baseline. The median weight loss was 11 lbs, but only 58% of the women maintained this weight loss through the first 5 year follow-up interval (1992-1997). Using both restricted cubic splines and multivariate Cox proportional hazards modeling, we observed no association between weight loss and postmenopausal breast cancer. The hazard ratio for 30+ pounds of weight loss compared to stable weight was 0.95 (95%: CI 0.47-1.95). An inverse association was, however, suggested among women who maintained ten or more pounds of weight loss through the next interval. There was no evidence of effect modification by postmenopausal hormone use, initial BMI, or other factors examined. In summary, weight loss was not associated with postmenopausal breast cancer in this study. Future studies should focus on sustained weight loss and whether the timing of weight loss is important.

    Background: Food reinforcement, ie, motivation to obtain food, is associated with energy intake and obesity. Finding ways to decrease the reinforcing value of unhealthy foods may help with adherence to diets and maintenance of weight loss. Our previous study in nonobese adults showed that daily consumption of the same snack food (food consumed apart from meals) for 14 d significantly decreased its reinforcing value. Objectives: The aims of this study were to replicate and extend these findings to obese individuals and to examine the effects of different portion sizes of snack foods on food reinforcement. Design: Food reinforcement and liking were tested in 31 obese and 27 nonobese women at baseline and after 2 wk of daily consumption of 0, 100, or 300 kcal/d of the same snack food. Results: We found a significant interaction of phase, portion size, and body mass index on the pattern of operant responding for food. Obese women had a significant increase in food reinforcement after consuming the 300-kcal portion of food for 2 wk, whereas nonobese women had the opposite response. No significant differences were found on the reinforcing value with the 0- and 100-kcal portion-size conditions. Women in the 300-kcal group (obese and nonobese) reported a significant decrease in snack food liking from baseline to after daily intake. Conclusions: These findings suggest that obese and nonobese women respond differently to the daily intake of a snack food and that this may not be a viable mechanism for reducing food reinforcement in obese women. This trial was registered at www.clinicaltrials.gov as NCT00837694. PMID:19458018

    Maternal obesity (defined as prepregnancy maternal BMI> or = 30 kg/m2) is a risk factor strongly associated with serious perinatal complications and its prevalence has increased rapidly in a general population during the last decades. Therefore, following international approach to regulate perinatal care in this population, Group of Experts of Polish Gynecological Society developed these new guidelines concerning perinatal care in obese pregnant women, including women after bariatric surgery. The recommendations cover detailed information on specific needs and risks associated with obesity in women of reproductive age, pregnancy planning, antenatal care, screening, prophylaxis and treatment for other pregnancy complications characteristic for maternal obesity fetal surveillance, intrapartum care and post-partum follow-up. Pregnancy planning in these patients should involve dietary recommendations aiming at well balanced diet and daily caloric uptake below 2000 kcal and modest but regular physical activity with sessions every two days starting from 15 min and increased gradually to 40 min. Laboratory work-up should include tests recommended in general population plus fasting glycemia and oral glucose tolerance if necessary thyroid function, lipidprofile, blood pressure and ECG. Patients after bariatric surgery should allow at least one year before they conceive and have their diet fortified with iron, folic acid, calcium and vit. B12. Antenatal care should include monitoring body weight gain with a target increase in body weight less than 7 kg, thromboprophylaxis, strict monitoring of blood pressure and diagnostic for gestational diabetes in early pregnancy. Fetal ultrasonic scans should be arranged following protocols recommended by US section of Polish Gynaecological Society with additional scan assessing fetal growth performed within 7 days before delivery and aiming at assessing a risk for shoulder dystocia in a patient.

    Obesity and its complications constitute a major health problem in postmenopausal women. The identification of the obesity phenotype, especially that of metabolically healthy obese (MHO) patients, is a necessary part of obesity treatment protocols. There are several methods to define MHO, but unfortunately, all of them are arbitrary and inconsistent. The aim of this work was to determine whether lipid accumulation product (LAP) could be used as a marker of the MHO phenotype in postmenopausal women. A sample of 345 Polish postmenopausal women aged 50-60years old participated in the study. Participants were classified as obese when their BMI was >27. Receiver operating characteristic curve analysis was performed to estimate the best cutoff for the LAP index value to identify postmenopausal women without metabolic syndrome components. We found that the best cutoff value was LAP ≤29.9, and this value was used to define MHO individuals. With this definition, the identification of MHO individuals could be made when both of the following criteria were met: LAP index ≤29.9 and no arterial hypertension (SBP<130mmHg, DBP<85mmHg). The anthropometric and body fat distribution measurements, as well as the metabolic characteristics of MHO women identified according to the above definition, were compared with those of MHO women identified by two other methods in the literature. These methods and our definition identified similar proportions of MHO women ranging from 11.6% to 16.9%. We found that MHO women identified by all of the definitions used in this study possessed a similar metabolic status, and they did not differ in anthropometric indices or body fat distribution measurements. We concluded that the combination of LAP estimation and arterial blood pressure measurement appear to constitute a useful method for identifying the MHO phenotype in postmenopausal women.

    Obesity is the fifth leading risk for death globally, and a significant challenge to global health. It is a common, complex, non-malignant disease and develops due to interactions between the genes and the environment. DNA methylation can act as a downstream effector of environmental signals; analysis of this process therefore holds substantial promise for identifying mechanisms through which genetic and environmental factors jointly contribute to disease risk. To assess the effects of excessive weight and obesity on gene-specific methylation levels of promoter regions, we determined the methylation status of four genes involved in inflammation and oxidative stress [interleukin 6 (IL6), tumor necrosis factor α (TNFα), mitochondrial transcription factor A (TFAM), and glucose transport 4 (GLUT4)] in blood cell-derived DNA from healthy women volunteers with a range of body mass indices (BMIs) by methylation-specific PCR. Interestingly, the samples from obese individuals (BMI ≥ 30 kg/m(2)) showed significantly increased hypermethylation for IL6 gene compared to normal weight (BMI < 23 kg/m(2)) and overweight samples (23 kg/m(2) ≤ BMI < 30 kg/m(2)) (P = 0.034 and P = 0.026). However, there was no statistically significant difference in promoter methylation of the other 3 genes between each group. These findings suggest that aberrant DNA methylation of IL6 gene promoter may play an important role in the etiology and pathogenesis of obesity and IL6 methylation could be used as molecular biomarker for obesity risk assessment. Further studies are required to elucidate the potential mechanisms underlying this relationship. PMID:25921605

    Background The effect of moderate weight loss on operational lung volumes during exercise and the oxygen (O2) cost of breathing are unknown in obese women but could have important implications regarding exercise endurance. Methods In twenty-nine obese women (33 ± 8yr, 97 ± 14kg, BMI: 36 ± 4, body fat: 45.6 ± 4.5%; means ± SD), body composition, fat distribution (by MRI), pulmonary function, operational lung volumes during exercise, and the O2 cost of breathing during eucapnic voluntary hyperpnea ( V˙O2 vs. V˙E slope) were studied before and after a 12-week diet and resistance exercise weight loss program. Results Participants lost 7.5 ± 3.1kg or ≈8% of body weight (p < 0.001), but fat distribution remained unchanged. After weight loss, lung volume subdivisions at rest were increased (p < 0.05) and were moderately associated (p < 0.05) with changes in weight. End-expiratory lung volume (%Total Lung Capacity) increased at rest and during constant load exercise (p < 0.05). O2 cost of breathing was reduced by 16% (2.52 ± 1.02 to 2.11 ± 0.72ml/L; P=0.003). As a result, O2 uptake of the respiratory muscles (V˙O2Resp), estimated as the product of O2 cost of breathing and exercise V˙E during cycling at 60W, was significantly reduced by 27 ± 31ml (P<0.001), accounting for 46% of the reduction in total body V˙O2 during cycling at 60W. Conclusions Moderate weight loss yields important improvements in respiratory function at rest and during submaximal exercise in otherwise healthy obese women. These changes in breathing load could have positive effects on the exercise endurance and adherence to physical activity. PMID:26869243

    Neighborhood environment is consistently associated with obesity; changes to modifiable aspects of the neighborhood environment may curb the growth of obesity in the US and other developed nations. However, currently the majority of studies are cross-sectional and thus not appropriate for evaluating causality. The goal of this study was to evaluate the effect of a neighborhood-changing intervention on changes in obesity among older women. Over the past 30 years the Portland, Oregon metropolitan region has made significant investments in plans, regulatory structures, and public facilities to reduce sprawl and increase compact growth centers, transit-oriented development approaches, and green space. We used geocoded residential addresses to link data on land-use mix, public transit access, street connectivity, and access to green space from four time points between 1986–2004, with longitudinal data on body mass index (BMI) from a cohort of 2,003 community-dwelling women aged 66 years and older. Height and weight were measured at clinic visits. Women self-reported demographics, health habits, and chronic conditions, and self-rated their health. Neighborhood socioeconomic status was assessed from census data. Neighborhood walkability and access to green space improved over the 18-year study period. On average there was a non-significant mean weight loss in the cohort between baseline (mean age 72.6 years) and the study’s end (mean age 85.0 years). We observed no association between neighborhood built environment or change in built environment and BMI. Greater neighborhood socioeconomic status at baseline was independently associated with a healthier BMI at baseline, and protected against an age-related decline in BMI over time. BMI decreases with age reflect increased frailty, especially among older adults with complex morbidities. Future research should consider the influence of the neighborhood environment on additional relevant health outcomes and should include

    The prevalence of vitamin D deficiency was reassessed in April and May 1971, 10 years after the discovery of widespread late rickets and osteomalacia in the Glasgow Pakistani community. Evidence of vitamin D deficiency was found in 28 out of 115 adults and children examined (24%). Children at the age of puberty were most severely affected by rickets, whereas most infants and younger children in the survey were protected by vitamin D supplements. Mild biochemical osteomalacia was common in Pakistani women. A total of 21 Pakistani and Indian children with rickets were admitted to Glasgow hospitals during 1968-70. These comprised 10 children with infantile rickets and 11 with late rickets. Four of the latter group required osteotomy for severe rachitic deformity. Late rickets and osteomalacia in Pakistani and Indian immigrants are not primarily due to nutritional deficiency of vitamin D, though the high phytate content of their diet may be of aetiological importance. A combination of environmental, social, and endogenous factors, the relative importance of which is not at present clear, may also be involved. Advice on the prophylaxis of vitamin D deficiency should be given to all Pakistani and Indian communities in the United Kingdom. PMID:5031709

    Background Few studies have examined dietary data or objective measures of physical activity (PA) and sedentary behavior among metabolically healthy overweight/obese (MHO) and metabolically unhealthy overweight/obese (MUO). Thus, the purpose is to determine whether PA, sedentary behavior and/or diet differ between MHO and MUO in a sample of young women. Methods Forty-six overweight/obese (BMI ≥25 kg/m2) African American and Caucasian women 19–35 years were classified by cardiometabolic risk factors, including elevated blood pressure, triglyceride, glucose and C-reactive protein, low high density lipoprotein, and insulin resistance (MUO ≥2; MHO, <2). Time (mins/day) in light, moderate, vigorous PA, and sedentary behavior were estimated using an accelerometer (≥3 days; ≥8 hrs wear time). Questionnaires were used to quantify sitting time, TV/computer use and usual daily activity. The Block Food Frequency Questionnaire assessed dietary food intake. Differences between MHO and MUO for lifestyle behaviors were tested with linear regression (continuous data) or logistic regression (categorical data) after adjusting for age, race, BMI, smoking and accelerometer wear and/or total kilocalories, as appropriate. Results Women were 26.7±4.7 years, with a mean BMI of 31.1±3.7 kg/m2, and 61% were African American. Compared to MUO (n = 9), MHO (n = 37; 80%) spent less mins/day in sedentary behavior (difference: -58.1±25.5, p = 0.02), more mins/day in light PA (difference: 38.2±16.1, p = 0.02), and had higher daily METs (difference: 0.21±0.09, p = 0.03). MHO had higher fiber intakes (g/day of total fiber, soluble fiber, fruit/vegetable fiber, bean fiber) and daily servings of vegetables; but lower daily dairy servings, saturated fat, monounsaturated fat and trans fats (g/day) compared to MUO. Conclusion Compared to MUO, MHO young women demonstrate healthier lifestyle habits with less sedentary behavior, more time in light PA, and healthier dietary quality for fat

    Breast cancer (BC) is considered a global public health problem, and is the most frequently type diagnosed in Mexican women. Therefore, it is important to study the risk factors associated to this neoplasia in order to establish prevention strategies. The aim of this study was to evaluate the effect of hormonal contraceptives and hormone therapy (HT) use and period of use, breastfeeding practice, abdominal obesity and weight gain in adulthood, on the risk of BC in adult women from Northwest Mexico. This was a case-control study that included 162 women (81 cases and 81 controls). A sociodemographic and health questionnaire, and a survey history of body weight were applied to participants. Measurements of body weight, height and waist circumference were performed. To assess the association between BC risk and exposing factors, a multivariate logistic regression model was used. Average age of cases and controls were 51.8 ± 11.7 and 51.4 ± 11.3 years, respectively. No significant association was found between the use and period of use of hormonal contraceptives and HT with the risk of BC. The practice of breastfeeding (OR=0.34, 95%CI: 0.12- 0.92) and the time of exclusive breastfeeding (OR=0.64, 95%CI: 0.42-0.97; crude) were protective against the risk of BC. Abdominal obesity (OR=0.93, 95%CI: 0.90-0.97) and weight gain in early adulthood (OR=0.90, 95%CI: 0.85-0.95) were inversely associated to the risk of BC. In conclusion, the practice of breastfeeding may help prevent BC in Mexican women. PMID:26262729

    Enhanced endometrial proliferation correlates obesity to type-I (estrogen-dependent) endometrial cancer (EC). Our aim was to distinguish obese women (without EC) with differing endometrial proliferation. Endometrial and blood samples were obtained from normal-weight and obese women without EC. Type-I EC samples were obtained from obese patients. On measuring endometrial proliferation (Ki67 and phosphorylated histone H3 (p-H3)), two groups of obese women without EC were identified: obese(High Proliferating) (O(HP)) and obese(Low Proliferating) (O(LP)). Increased Ki67 (88.5%, P<0.001), p-H3 (62.6%, P<0.01), 17β-estradiol/progesterone ratio (46.3%, P<0.01) and endometrial estrogen receptor alpha (ERα) (82.2%, P<0.001) were observed in O(HP) compared with O(LP) patients. ECs possessed similar ERα and enhanced proliferation as O(HP), suggesting that O(HP) women are at higher risk of type-I EC. O(LP) women were indistinguishable from normal-weight women regarding these determinants of endometrial proliferation, ERα and 17β-estradiol/progesterone ratio. Our data may further define the obesity phenotype in regards to type-I EC risk and may help identify obese women more susceptible to develop type-I EC, allowing early intervention and a potential reduction in mortality.

    Background Asians are at increased risk of morbidity at a lower body mass index (BMI) than European Whites, particularly relating to metabolic risk. UK maternal obesity guidelines use general population BMI criteria to define obesity, which do not represent the risk of morbidity among Asian populations. This study compares incidence of first trimester obesity using Asian-specific and general population BMI criteria. Method A retrospective epidemiological study of 502,474 births between 1995 and 2007, from 34 maternity units across England. Data analyses included a comparison of trends over time between ethnic groups using Asian-specific and general population BMI criteria. Logistic regression estimated odds ratios for first trimester obesity among ethnic groups following adjustment for population demographics. Results Black and South Asian women have a higher incidence of first trimester obesity compared with White women. This is most pronounced for Pakistani women following adjustment for population structure (OR 2.19, 95% C.I. 2.08, 2.31). There is a twofold increase in the proportion of South Asian women classified as obese when using the Asian-specific BMI criteria rather than general population BMI criteria. The incidence of obesity among Black women is increasing at the most rapid rate over time (p=0.01). Conclusion The twofold increase in maternal obesity among South Asians when using Asian-specific BMI criteria highlights inequalities among pregnant women. A large proportion of South Asian women are potentially being wrongly assigned to low risk care using current UK guidelines to classify obesity and determine care requirements. Further research is required to identify if there is any improvement in pregnancy outcomes if Asian-specific BMI criteria are utilised in the clinical management of maternal obesity to ensure the best quality of care is provided for women irrespective of ethnicity.

    This study examined the association of autonomy-related variables, including exercise motivation, with psychological well-being and quality of life, during obesity treatment. Middle-aged overweight/obese women (n = 239) participated in a 1-year behavioral program and completed questionnaires measuring need support, general self-determination, and exercise and treatment motivation. General and obesity-specific health-related quality of life (HRQOL), self-esteem, depression, and anxiety were also assessed. Results showed positive correlations of self-determination and perceived need support with HRQOL and self-esteem, and negative associations with depression and anxiety (P < .001). Treatment autonomous motivation correlated positively with physical (P = .004) and weight-related HRQOL (P < .001), and negatively with depression (P = .025) and anxiety (P = .001). Exercise autonomous motivation was positively correlated with physical HRQOL (P < .001), mental HRQOL (P = .003), weight-related HRQOL (P < .001), and self-esteem (P = .003), and negatively with anxiety (P = .016). Findings confirm that self-determination theory's predictions apply to this population and setting, showing that self-determination, perceived need support, and autonomous self-regulation positively predict HRQOL and psychological well-being.

    Obese women with polycystic ovary syndrome (PCOS) may have impairment in the regulation of food intake associated with ghrelin and insulin. In order to compare postprandial ghrelin and insulin responses to an ad libitum meal, we assessed 30 obese women with PCOS and 23 obese women without PCOS (control group). Blood samples were taken under fasting conditions, preprandially, and 15, 45, 75, and 135 minutes after the beginning of an ad libitum meal and ghrelin and insulin concentrations were analyzed. Insulin resistance (IR) was classified using basal insulin, quantitative insulin sensitivity check index, and homeostasis model assessment index. Mean ad libitum food intake was similar between the groups (468 ± 150 vs 444 ± 165 g, P = .60). The IR was found in 56.6% in PCOS group compared with 30.4% in the control group (P < .01). The postprandial ghrelin response was similar in both the groups but the insulin area under the curve (AUC) tend to be greater in the PCOS group (12807 ± 8149.4 vs 8654.4 ± 7232.3 μIU/mL/min; P = .057). The ghrelin AUC was negatively correlated with the insulin AUC (r = -.5138; P = .01) only in the control group. The imbalance in the feedback mechanisms between insulin and ghrelin, present in obese women, especially those with IR, may affect food intake throughout the day and that could be a mechanism for the development of obesity in PCOS.

    Context Obesity is associated with insulin-resistance (IR), the key feature of type 2 diabetes. Although chronic low-grade inflammation has been identified as a central effector of IR development, it has never been investigated simultaneously at systemic level and locally in skeletal muscle and adipose tissue in obese humans characterized for their insulin sensitivity. Objectives We compared metabolic parameters and inflammation at systemic and tissue levels in normal-weight and obese subjects with different insulin sensitivity to better understand the mechanisms involved in IR development. Methods 30 post-menopausal women were classified as normal-weight insulin-sensitive (controls, CT) and obese (grade I) insulin-sensitive (OIS) or insulin-resistant (OIR) according to their body mass index and homeostasis model assessment of IR index. They underwent a hyperinsulinemic-euglycemic clamp, blood sampling, skeletal muscle and subcutaneous adipose tissue biopsies, an activity questionnaire and a self-administrated dietary recall. We analyzed insulin sensitivity, inflammation and IR-related parameters at the systemic level. In tissues, insulin response was assessed by P-Akt/Akt expression and inflammation by macrophage infiltration as well as cytokines and IκBα expression. Results Systemic levels of lipids, adipokines, inflammatory cytokines, and lipopolysaccharides were equivalent between OIS and OIR subjects. In subcutaneous adipose tissue, the number of anti-inflammatory macrophages was higher in OIR than in CT and OIS and was associated with higher IL-6 level. Insulin induced Akt phosphorylation to the same extent in CT, OIS and OIR. In skeletal muscle, we could not detect any inflammation even though IκBα expression was lower in OIR compared to CT. However, while P-Akt/Akt level increased following insulin stimulation in CT and OIS, it remained unchanged in OIR. Conclusion Our results show that systemic IR occurs without any change in systemic and tissues

    Trekking includes downhill walking and enhances lower limb strength. Muscle fitness is a predictor of mortality and is associated with cardiovascular risk factors in adults. The purpose of this study was to investigate the effects of trekking on cardiovascular health and fitness in older obese women. The participants were randomly assigned to an exercise group (EG, n= 32) and a control group (CG, n= 48). The EG participated in the trekking program for 12 weeks, 3 times per week, and 90 min per session, at a moderate intensity. Cardiovascular health (BMI, percentage of body fat, blood pressure, glucose, triglycerides, and total cholesterol) and fitness (muscle strength, muscle endurance, balance, and flexibility) were measured before and after the 12-week program. A twoway repeated ANOVA was used to compare and analyze the group differences. Body weight, systolic blood pressure, and muscle strength were significantly different between the groups. These results indicate that trekking played a significant role in the reduction of weight and systolic blood pressure in obese women. The results of this study can be utilized to reduce cardiovascular risk factors associated with aging. PMID:25210697

    [Purpose] This study investigated the effect of the use of trekking poles on muscle and cartilage damage and fatigue during downhill walking in obese women. [Subjects and Methods] Subjects included eight obese women who had a body fat percentage greater than 30. Subjects performed downhill walking without a trekking pole (NP) and with a trekking pole (TP) at 50% heart rate reserve for 30 minutes on a treadmill. The treadmill was set at a 15% downhill declination. Blood samples were collected to examine muscle damage (serum creatine kinase [CK] and lactate dehydrogenase [LDH] levels), cartilage damage (serum cartilage oligomeric matrix protein [COMP] levels), and fatigue (plasma lactate levels) at the pre-walking baseline (PWB), immediately after walking (IAW), and 2 hours post-walking (2HPW). [Results] The CK, LDH, COMP, and lactate levels were significantly increased IAW when compared with those at the PWB in both trials. In addition, in the NP trial, the CK, LDH, and COMP levels were significantly increased at 2HPW when compared with those at the PWB. [Conclusion] Downhill walking can cause muscle and cartilage damage, and our results suggest that the use of a trekking pole can reduce temporary muscle and cartilage damage after downhill walking.

    Evolution and quality of the diet of women with severe and morbid obesity undergoing gastric bypass. The objective of this study was to evaluate the changes of dietary intake and quality of the diet in patients undergoing gastric bypass. In forty-four women with severe and morbid obesity it was assessed their nutrient intakes before and 6, 12, and 18 months after gastric bypass by using three-day food records. Vitamin and mineral intakes from supplements were strictly controlled though personalized records. With the exceptions of calcium and vitamin A, energy and nutrient intakes were significantly decreased at 6, 12, and 18 month after bypass compared to the pre-surgery period. Dietary intakes of calcium, iron, zinc, copper, folic acid, vitamin C, and vitamin E were below 100% of adequacy from the 6th month after the surgery and thereafter. This situation is reverted when nutrient intakes supplied by supplements are taken into account. Although a "U" shape trend was observed in the nutrient intakes results during the experimental period, in most cases the differences between the observed values at month 12 and 18 were not significant. In conclusion, these patients had important reductions of their energy and nutrient intakes as result of gastric bypass. Routine supplements may correct this situation, nevertheless, the anatomical alterations inherent to this type of surgery may cause that total nutrient intakes reaching adequacy values slightly above 100%, may not necessarily be able to avoid the development of nutritional deficiencies.

[Subjects] The study included 26 obese women aged 30–60 years. [Methods] The subjects were randomly divided into two groups, with 13 subjects in each group: self-selected intensity and imposed intensity (10% above ventilatory threshold) groups. All subjects completed an intervention program that lasted 12 weeks, with three exercise sessions a week. The rating of perceived exertion and affective responses (Feeling Scale and Felt Arousal Scale) were monitored in the first, sixth, and twelfth weeks. [Results] Significant differences were observed between groups in heart rate and rating of perceived exertion. The affective responses during exercise were more negative in the imposed intensity group. [Conclusion] Use of a self-selected exercise intensity can promote smaller negative affective responses during exercise and provide a sufficient stimulus for improvement in cardiorespiratory fitness.

    Background: Polycystic ovary syndrome (PCOS) is of clinical and public health importance, affecting up to one in five women of reproductive age. It has significant and diverse clinical implications including reproductive, metabolic, and psychological features. Aim: The study was to investigate the effect of anti-inflammatory dietary combo on metabolic, endocrine, inflammatory, and reproductive profiles in overweight and obese women with PCOS. Materials and Methods: A total of 100 nonpregnant, overweight, and obese adult females with PCOS according to the Rotterdam criteria, were screened during the year 2012, and 75 completed the trial. At baseline and study end, fasting blood samples were drawn to measure biological markers, body fat percent (BFP), and visceral fat area (VFA) were assessed by the InBody720 device and anthropometric measurements were done for all participants who were subjected to an anti-inflammatory hypocaloric diet and physical activity for 12 weeks. Results: At study completion, we achieved moderate weight loss of (± 7%) and significant improvements in body composition, hormones and menstrual cyclicity, blood pressure, glucose homeostasis, dyslipidemia, C-reactive protein (CRP), and serum amyloid A (SAA) (surrogate measures of cardiovascular risk (CVR)). This was a clinically relevant weight loss that is associated with a reduced prevalence of type 2 diabetes mellitus (DM2) and metabolic syndrome (MS) in the general population and improved fertility outcomes in PCOS. We achieved 63% regain of menstrual cyclicity and 12% spontaneous pregnancy rate within 12 week. Conclusions: We have explored an additional dietary treatment option with good prognostic metabolic and reproductive responses to weight loss that occur in overweight and obese PCOS. PMID:26258078

    Major depressive disorder (MDD) is prevalent in clinical weight-loss settings and predicts poor weight-loss outcomes. It is unknown whether the severity of depressive symptoms among those with MDD is associated with diet quality or physical activity levels. This knowledge is important for improving weight-loss treatment for these patients. It was hypothesized that more severe depression is associated with poorer diet quality and lower physical activity levels among individuals with obesity and MDD. Participants were 161 women with current MDD and obesity enrolled in the baseline phase of a weight-loss trial between 2007 and 2010. Depression severity was measured with the Beck Depression Inventory II. The Alternate Healthy Eating Index was applied to data from three 24-hour diet recalls to capture overall diet quality. Daily metabolic equivalents expended per day were calculated from three 24-hour physical activity recalls. Greater depression severity was associated with poorer overall diet quality (estimate=-0.26, standard error 0.11; P=0.02), but not with physical activity (estimate=0.07, standard error 0.05; P=0.18), in linear regression models controlling for income, education, depression-related appetite change, binge eating disorder, and other potential confounds. Associations with diet quality were primarily driven by greater intake of sugar (r=0.20; P<0.01), saturated fat (r=0.21; P<0.01), and sodium (r=0.22; P<0.01). More severe depression was associated with poorer overall diet quality, but not physical activity, among treatment-seeking women with MDD and obesity. Future studies should identify mechanisms linking depression to diet quality and determine whether diet quality improves with depression treatment. PMID:22709773

    The "time bomb is ticking" because there is an obesity crisis associated with higher rates of chronic diseases such as stroke, hypertension, type 2 diabetes, and some forms of cancer in African-American women compared to White women. African-American women incur higher medical costs from hospitalizations, decreased productivity in the work setting, lost wages, the needfor medical benefits and pharmacy-associated costs, and more time away from family than White women. Numerous factors, such as the socio-cultural context of eating, acceptance of a larger weight status, the emotionally liberating effects offood, and preference for highfat and high caloric, sugary-content, and sodium-laden food influences the obesity crisis in African-American women. The interplay of poverty and lower socioeconomic status, residential segregation, health literacy, availability of fast foods and scarce produce in local convenience food marts, physical inactivity, and conflicting messages from social media public service announcements (PSAs) and ads in national magazines affect the obesity crisis in African-American women. There is an urgent call for sustainable, community-driven health policy initiatives that improve access to healthy foods in lower-income, minority communities. Furthermore, African-American women are challenged to modify their health behaviors by preparing healthy meals for themselves and theirfamilies, and by engaging in physical activity. PMID:27045156

    The objectives of this study were 1) to describe maternal glucose and lipid kinetics and 2) to examine the relationships with infant birth weight in obese women with pregestational type 2 diabetes during late pregnancy. Using stable isotope tracer methodology and mass spectrometry, maternal glucose and lipid kinetic rates during the basal condition were compared in three groups: lean women without diabetes (Lean, n = 25), obese women without diabetes (OB, n = 26), and obese women with pregestational type 2 diabetes (OB+DM, n = 28; total n = 79). Glucose and lipid kinetics during hyperinsulinemia were also measured in a subset of participants (n = 56). Relationships between maternal glucose and lipid kinetics during both conditions and infant birth weight were examined. Maternal endogenous glucose production (EGP) rate was higher in OB+DM than OB and Lean during hyperinsulinemia. Maternal insulin value at 50% palmitate Ra suppression (IC50) for palmitate suppression with insulinemia was higher in OB+DM than OB and Lean. Maternal EGP per unit insulin and plasma free fatty acid concentration during hyperinsulinemia most strongly predicted infant birth weight. Our findings suggest maternal fatty acid and glucose kinetics are altered during late pregnancy and might suggest a mechanism for higher birth weight in obese women with pregestational diabetes.

    Objective To determine the effect of antenatal dietary and lifestyle interventions on health outcomes in overweight and obese pregnant women. Design Multicentre randomised trial. We utilised a central telephone randomisation server, with computer generated schedule, balanced variable blocks, and stratification for parity, body mass index (BMI) category, and hospital. Setting Three public maternity hospitals across South Australia. Participants 2212 women with a singleton pregnancy, between 10+0 and 20+0 weeks’ gestation, and BMI ≥25. Interventions 1108 women were randomised to a comprehensive dietary and lifestyle intervention delivered by research staff; 1104 were randomised to standard care and received pregnancy care according to local guidelines, which did not include such information. Main outcome measures Incidence of infants born large for gestational age (birth weight ≥90th centile for gestation and sex). Prespecified secondary outcomes included birth weight >4000 g, hypertension, pre-eclampsia, and gestational diabetes. Analyses used intention to treat principles. Results 2152 women and 2142 liveborn infants were included in the analyses. The risk of the infant being large for gestational age was not significantly different in the two groups (lifestyle advice 203/1075 (19%) v standard care 224/1067 (21%); adjusted relative risk 0.90, 95% confidence interval 0.77 to 1.07; P=0.24). Infants born to women after lifestyle advice were significantly less likely to have birth weight above 4000 g (lifestyle advice 164/1075 (15%) v standard care 201/1067 (19%); 0.82, 0.68 to 0.99; number needed to treat (NNT) 28, 15 to 263; P=0.04). There were no differences in maternal pregnancy and birth outcomes between the two treatment groups. Conclusions For women who were overweight or obese, the antenatal lifestyle advice used in this study did not reduce the risk delivering a baby weighing above the 90th centile for gestational age and sex or improve maternal

    Weight loss outcomes in overweight and obese individuals may be influenced by individual weight loss expectations (WLEs). Research on these phenomena in older women is lacking. This cross-sectional study compared groups of younger and older women on their WLEs and related attitudes (body dissatisfaction and disordered eating). Twenty-six younger (18-38 years) and 33 older (60-78 years) overweight and obese women were recruited from a weight loss clinic, prior to treatment. Disordered eating attitudes and body dissatisfaction were assessed using validated questionnaires and a pictorial figure-choice scale. Participants reported 10 WLEs categorized according to personal, lifestyle and social factors. Overall, women with a higher body mass index had greater WLEs. Older women reported lower WLEs than younger women (-14.5 kg vs. -22.4 kg) in all categories except past weight. Older women perceived that career success would necessitate the greatest level of weight loss (-18.5 kg), whereas younger women derived their greatest WLEs from mass media (-28.5 kg). Both older and younger groups perceived that their families would be supportive of the smallest amount of weight loss (-8.4 and -17.6 kg, respectively). The groups did not differ on body dissatisfaction, but younger women's disordered eating attitudes were significantly higher (p < .001). Older overweight and obese women have lower WLEs than younger women but experience similar levels of body dissatisfaction and healthier eating attitudes. The attitudinal constructs underlying these differences may be useful in clinical practice to tailor age-specific weight loss interventions. PMID:25872866

    Background Metabolically benign obese individuals have a 10-year cardiovascular disease (CVD) risk comparable to healthy normal weight individuals. However, the burden of subclinical CVD among metabolically benign obese is not well known. Methods In cross-sectional analyses of 475 mid-life women, we compared common carotid artery intima media thickness (CCA-IMT), aortic pulse wave velocity (aPWV) and coronary (CAC) and aortic calcification (AC) among three groups: healthy normal weight, metabolically benign overweight/obese (<3 metabolic syndrome components/elevated CRP), and at-risk overweight/obese (≥3 metabolic syndrome components/elevated CRP). Results The mean (SD) CCA-IMT and aPWV were lowest in the normal weight group (n=145), followed by the benign overweight/obese (n=260) and at-risk overweight/obese (n=70) groups [CCA-IMT: 0.64 (0.08) vs. 0.68 (0.09) vs. 0.73 (0.13) mm, p<0.001; aPWV: 731.0 (176.4) vs. 809.9 (182.3) vs. 875.7 (228.8) cm/s, p<0.001]. Similar results were found for the frequency (%) of women with increased CAC and AC [CAC: 13 (9%) vs. 53(20%) vs. 28(40%), p<0.001; AC: 47(32%) vs. 130 (50%) vs. 55(79%), p<0.001]. These differences remained significant after multivariable adjustment. Further adjustment for BMI attenuated the statistical significance of differences in aPWV and calcification between benign and at-risk overweight/obese women, but had little effect on the magnitude of these differences. Conclusions Metabolically benign overweight/obese women have a significantly greater subclinical CVD burden than normal weight women, despite published data finding similar CVD event rates between the two groups. Prospective studies tracking the progression of subclinical atherosclerosis to clinical CVD in these women are needed. PMID:21310415

    Aims The present study aimed to investigate relationships among abdominal obesity, metabolic abnormalities, and the prevalence of chronic kidney disease (CKD) in relatively lean Japanese men and women. Participants and methods The participants included 8133 men and 15 934 women between 40 and 75 years of age recruited from the government health check-up center in Kanazawa City, Japan. The prevalence of abdominal obesity, high blood pressure, dyslipidemia, and high fasting plasma glucose levels were assessed according to the Japanese criteria for metabolic syndrome. The estimated glomerular filtration rate (eGFR) was calculated using the modified Modification of Diet in Renal Disease equation for the Japanese population, and participants with an eGFR <60 mL/min/1.73 m2 and/or proteinuria were diagnosed with CKD. Results Overall, 23% of males and 14% of females met criteria for CKD. Having more numerous complicated metabolic abnormalities was significantly associated with a higher odds ratio (OR) of CKD for men and women, irrespective of abdominal obesity. However, there was a sex difference in the OR of CKD for obese participants without metabolic abnormalities, such that abdominal obesity without metabolic abnormalities was significantly associated with a higher OR for men (multivariate-adjusted OR 1.63; 95% confidence interval [CI], 1.16–2.28) but not for women (OR 1.01; 95% CI, 0.71–1.44). Conclusions The present findings demonstrated that obesity without metabolic abnormalities was associated with a higher risk of CKD in men but not women in a relatively lean Japanese population.

    This study examined relationships between three measures of park availability and self-reported physical activity (PA), television viewing (TV) time, and overweight/obesity among women from Australia and the United States. Having more parks near home was the only measure of park availability associated with an outcome. Australian women (n=1848) with more parks near home had higher odds of meeting PA recommendations and lower odds of being overweight/obese. In the US sample (n=489), women with more parks near home had lower odds of watching >4h TV per day. A greater number of parks near home was associated with lower BMI among both Australian and US women. Evidence across diverse contexts provides support to improve park availability to promote PA and other health behaviors. PMID:26828409

    Despite their low cost and high nutrient density, the contribution of eggs to nutrient intake and dietary quality among Mexican-American postpartum women has not been evaluated. Nutrient intake and dietary quality, as assessed by the Healthy Eating Index 2010 (HEI-2010), were measured in habitually sedentary overweight/obese (body mass index (BMI) = 29.7 ± 3.5 kg/m2) Mexican-American postpartum women (28 ± 6 years) and compared between egg consumers (n = 82; any egg intake reported in at least one of three 24-h dietary recalls) and non-consumers (n = 57). Egg consumers had greater intake of energy (+808 kJ (193 kcal) or 14%; p = 0.033), protein (+9 g or 17%; p = 0.031), total fat (+9 g or 19%; p = 0.039), monounsaturated fat (+4 g or 24%; p = 0.020), and several micronutrients than non-consumers. Regarding HEI-2010 scores, egg consumers had a greater total protein foods score than non-consumers (4.7 ± 0.7 vs. 4.3 ± 1.0; p = 0.004), and trends for greater total fruit (2.4 ± 1.8 vs. 1.9 ± 1.7; p = 0.070) and the total composite HEI-2010 score (56.4 ± 12.6 vs. 52.3 ± 14.4; p = 0.082). Findings suggest that egg intake could contribute to greater nutrient intake and improved dietary quality among postpartum Mexican-American women. Because of greater energy intake among egg consumers, recommendations for overweight/obese individuals should include avoiding excessive energy intake and incorporating eggs to a nutrient-dense, fiber-rich dietary pattern.

    Self-selected food intake of 15 reduced-obese women living in a metabolic ward was studied for 14 consecutive days to determine the effect of exercise and other metabolic and behavioral variables on energy intake. A choice of prepared food items were offered at breakfast, lunch and dinner, and a variety of additional food items were available continuously 24 h/day. Subjects performed either moderate intensity aerobic exercise (A-EX) (n = 8) expending 354 +/- 76 kcal/session or low intensity resistance weight training (R-EX)(n =7) expending 96 +/- kcal/session, 5 days/week. Mean energy intakes (kcal/day, +/- SEM) of the exercise groups were similar: 1867 +/- 275 for A-EX, 1889 +/- 294 for R-EX. Mean energy intakes of individuals ranged from 49 to 157% of the predetermined level required for weight maintenance. Resting metabolic rate per kg 0.75 and the Eating Inventory hunger score contributed significantly to the between subject variance in energy intake, whereas exercise energy expenditure did not. Regardless of exercise, eight women consistently restricted their energy intake (undereaters), and seven other consumed excess energy (overeaters). Overeaters were distinguished by higher Eating Inventory disinhibition (P = 0.023) and hunger (p = 0.004) scores. The overeaters' diet had a higher fat content 34 +/- 1% (p = 0.007). Also, overeaters took a larger percentage of their daily energy, than that of undereaters, 27 +/- 1 energy intake in the evening, 13 +/- 2%, compared to undereaters, 7 +/- 1% (p = 0.005). We conclude that the Eating Inventory is useful for identifying reduced-obese women at risk of overeating, and these individuals may benefit from dietary counseling aimed at reducing fat intake and evening snacking.

    Background The effectiveness of exercise training for preventing excessive gestational weight gain (GWG) and gestational diabetes mellitus (GDM) is still uncertain. As maternal obesity is associated with both GWG and GDM, there is a special need to assess whether prenatal exercise training programs provided to obese women reduce the risk of adverse pregnancy outcomes. Our primary aim was to assess whether regular supervised exercise training in pregnancy could reduce GWG in women with prepregnancy overweight/obesity. Secondary aims were to examine the effects of exercise in pregnancy on 30 outcomes including GDM incidence, blood pressure, blood measurements, skinfold thickness, and body composition. Methods and Findings This was a single-center study where we randomized (1:1) 91 pregnant women with a prepregnancy body mass index (BMI) ≥ 28 kg/m2 to exercise training (n = 46) or control (standard maternity care) (n = 45). Assessments were done at baseline (pregnancy week 12–18) and in late pregnancy (week 34–37), as well as at delivery. The exercise group was offered thrice weekly supervised sessions of 35 min of moderate intensity endurance exercise and 25 min of strength training. Seventeen women were lost to follow-up (eight in the exercise group and nine in the control group). Our primary endpoint was GWG from baseline testing to delivery. The principal analyses were done as intention-to-treat analyses, with supplementary per protocol analyses where we assessed outcomes in the women who adhered to the exercise program (n = 19) compared to the control group. Mean GWG from baseline to delivery was 10.5 kg in the exercise group and 9.2 kg in the control group, with a mean difference of 0.92 kg (95% CI −1.35, 3.18; p = 0.43). Among the 30 secondary outcomes in late pregnancy, an apparent reduction was recorded in the incidence of GDM (2009 WHO definition) in the exercise group (2 cases; 6.1%) compared to the control group (9 cases; 27.3%), with an odds ratio

    The aim of the present study was to determine the association between the thickness of preperitoneal fat (PFT), utilized as an indicator of visceral fat deposition, and the risk of premalignant and malignant changes of endometrial polyps (EPs) in overweight and obese women. Overweight and obese women who had undergone diagnostic outpatient hysteroscopy and subsequent endometrial polypectomy between January 2010 and May 2013 were analyzed. Each patient underwent a transabdominal ultrasound for the purpose of measuring the thickness of preperitoneal fat. A total of 146 overweight or obese women were analyzed. The overall incidence of malignant or premalignant lesions was 8.2%. Notably, 5 patients (3.4%) received a histopathological diagnosis of complex hyperplasia with atypia, while polyps harboring carcinoma were diagnosed in 7 cases (4.8%). A significantly increased PFT was observed in women exhibiting preneoplastic and neoplastic lesions, compared with women with benign EPs (mean ± SD, 23.2±3.7 vs. 15.9±8.3; P<0.01). Patient age of >60 years was significantly associated with malignant progression of EPs, while body mass index, menopausal status, arterial hypertension, diabetes, abnormal uterine bleeding, hormone replacement therapy and tamoxifen treatment demonstrated no significant association with the development of preneoplastic and neoplastic lesions of the endometrium. In a multivariate analysis, only PFT maintained a significant correlation with the diagnosis of preneoplastic and neoplastic lesions on EPs (odds ratio, 1.14; 95% confidence interval, 1.04–1.26). Ultrasound evaluation of PFT in overweight and obese women may be useful for the identification of a particularly high-risk subgroup of women. Therefore, regardless of symptoms or additional clinical variables, these particularly high-risk women require appropriate counseling and prompt surgical removal of EPs. PMID:26998162

    The small Pacific Island nation of Palau has alarmingly high rates of betel nut with tobacco use and obesity among the entire population including pregnant women. This study aimed to determine the effects of betel nut with tobacco use and pre-pregnancy obesity on adverse birth outcomes. This study used retrospective cohort data on 1171 Palauan women who gave birth in Belau National Hospital in Meyuns, Republic of Palau between 2007 and 2013. The exposures of interest were pre-pregnancy obesity and reported betel nut with tobacco use during pregnancy. The primary outcomes measured were preterm birth and low birth weight among full-term infants. A significantly increased risk for low birth weight among full-term infants was demonstrated among those women who chewed betel nut with tobacco during pregnancy when other known risk factors were controlled for. Additionally, pre-pregnancy obesity was associated with a significantly increased risk for preterm birth when other known risk factors were controlled for. Both betel nut with tobacco use and pre-pregnancy obesity were associated with higher risks for adverse birth outcomes. These findings should be used to drive public health efforts in Palau, as well as in other Pacific Island nations where these studies are currently lacking. PMID:26994610

    Although environmental factors are important, there is considerable evidence that genes also have a significant role in the pathogenesis of obesity. We conducted a population-based study to investigate the relationship between candidate genes for obesity (UCP1, UCP2, ADRA2B, ADRB3, LEPR, VDR and ESR1) and adiposity measures (body mass index, body fat percentage, weight, waist circumference and waist-hip ratio) in terms of individual gene and gene x gene interaction in models unadjusted and adjusted for covariates (age, years since menopause, educational level and total energy intake). Postmenopausal women with TC genotype of ESR1 gene had higher body fat percentage than those with TT genotype in the models unadjusted and adjusted for the covariates (P = 0.006 in adjusted model). In multiple logistic regression analysis, BsmI and ApaI SNPs of VDR genes were significantly associated with overweight and obesity. The UCP2-VDR ApaI interaction to susceptibility of overweight and obesity was first observed from logistic regression analysis, and then confirmed in the multifactor dimensionality reduction method unadjusted and adjusted for the covariates. This interaction had 69.09% prediction accuracy for overweight and obesity (P = 0.001, sign test). In conclusion, the study suggests the significant association of ESR1 and VDR genes with adiposity measures and the UCP2-VDR ApaI interaction to susceptibility to being overweight and obesity in postmenopausal Vietnamese women.

    The purpose of this study was to examine the effects of resistance training (RT) on sarcopenic obesity (SO) in older women. 243 older women underwent body composition measurement using dual-energy X-ray absorptiometry, and the SO index was calculated. This randomized controlled trial adopted from the baseline sample, 113 volunteers (67.0±5.2years) were randomly assigned to a control group (CG, n=64) or an experimental group (EG, n=69). The EG took part in a 24-week RT program, conducted three times per week. Body composition measurements were repeated at the end of the training program. RT induced a significant increase in fat-free mass (P<0.01), but not decrease in fat mass in the EG. Moreover, the SO index was also significantly improved in the EG (P<0.01), while it decreased significantly in the CG (P<0.01). It is concluded that RT is an effective approach to promote body composition alterations in older women, and it might improve SO-related phenotypes. PMID:27057600

    Saliva is a non-invasive source of biomarkers useful in the study of physiological mechanisms. Moreover, this fluid has diverse functions, among which food perception and ingestion, making it particularly suitable for the study of obesity. The aims of this study were to assess changes in salivary proteome among morbidly obese women, with a view to provide information about mechanisms potentially related to the development of obesity, and to evaluate whether these changes persist after weight loss. Mixed saliva samples from morbidly obese women (N = 18) who had been either subjected (group O-BS) or not (group O) to bariatric surgery and women with normal weight (N = 14; group C) were compared for protein profiles, alpha-amylase abundance and enzymatic activity, and carbonic anhydrase (CA) VI abundance. Differences in salivary obese profiles were observed for 23 different spots. Zinc-alpha-2 glycoprotein-containing spots showed higher abundance in group O only, whereas cystatin S-containing spots presented higher abundance in the two groups of obese subjects. Most of the spots identified as salivary amylase were present at lower levels in group O-BS. With regard to the amylase enzymatic activity, increases were observed for group O and decreases for group O-BS. One interesting finding was the high correlation between levels of CA VI and body mass index in group O, which was not observed for groups O-BS or C. The differences between groups, mainly regarding salivary proteins involved in taste sensitivity and metabolism, point to the potential of using saliva in the study of obesity development.

    Objective To analyze in obese women the acute effects of the breath stacking technique on thoraco-abdominal expansion. Design and Methods Nineteen obese women (BMI≥30 kg/m2) were evaluated by anthropometry, spirometry and maximal respiratory muscle pressures and successively analyzed by Opto-Electronic Plethysmography and a Wright respirometer during quiet breathing and breath stacking maneuvers and compared with a group of 15 normal-weighted healthy women. The acute effects of the maneuvers were assessed in terms of total and compartmental chest wall volumes at baseline, end of the breath stacking maneuver and after the maneuver. Obese subjects were successively classified into two groups, accordingly to the response during the maneuver, group 1 = prevalent rib cage or group 2 = abdominal expansion. Results Age was significantly lower in group 1 than group 2. When considering the two obese groups, FEV1 was lower and minute ventilation was higher only in group 2 compared to controls group. During breath stacking, inspiratory capacity was significant differences in obese subjects with a smaller expansion of the pulmonary rib cage and a greater expansion of the abdomen compared to controls and also between groups 1 and 2. A significant inverse linear relationship was found between age and inspiratory capacity of the pulmonary rib cage but not of the abdomen. Conclusions In obese women the maximal expansion of the rib cage and abdomen is influenced by age and breath stacking maneuver could be a possible therapy for preventing respiratory complications.

    This study examined the effects of Korean red ginseng (KRG) on obese women and aimed to confirm that the effects of KRG on obesity differ dependently on a gene. Fifty obese women were recruited and randomized to receive KRG (n=24) or placebo (n=26) for 8 wk. Measurements of blood pressure, height, weight, waist circumference, waist-hip ratio (WHR), total fat mass, percentage of body fat, resting metabolic rate, basal body temperature, and daily food intake (FI), blood test (serum lipid, liver and renal function), Korean version of obesity-related quality of life scale (KOQOL), and a gene examination were performed. Comparisons of subjects before and after the administration of KRG revealed significant improvements of obesity in terms of weight, body mass index (BMI), WHR, FI, and KOQOL. However, in the comparison between KRG group and placebo group, only KOQOL was significantly different. KRG displayed significant efficacy on BMI and KOQOL in the CT genotype of the G protein beta 3 gene, but not in the CC genotype, on blood sugar test in the Trp64/Arg genotype of the beta 3 adrenergic receptor gene, but not in Trp64/ Trp genotype, on KOQOL in the DD genotype of the angiotensin I converting enzyme gene, but not in the ID and DD genotypes. The effects of KRG on obesity were confirmed to some extent. However, a distinct effect compared to placebo was not confirmed. KRG is more effective for improving the secondary issues of the quality of life derived from obesity rather than having direct effects on the obesity-related anthropometric assessment and blood test indices.

    Objective To evaluate prognostic risk factors for survival in women with low grade serous epithelial ovarian cancer (LGSC). Methods A multicenter retrospective analysis of patients with LGSC was conducted. Potential epidemiologic risk factors evaluated included obesity, age, parity, race, smoking, oral contraceptive pill and/or hormonal replacement therapy use, and previous hysterectomy or surgery on fallopian tubes and/or ovaries. Additional factors included stage, extent of debulking, residual disease, and disease status. Results Eighty-one patients were identified, and pathological diagnosis was independently confirmed. Median age of diagnosis was 56 years (range: 21 to 86). Thirty-four percent were obese, and 80% had optimally debulked disease. Forty-six percent were alive, 14% with disease; while 25% were dead of disease; 2% died of intercurrent disease; and 27% had an unknown status. In a univariate analysis, optimal surgical debulking was associated with improved PFS (p=0.01), DSS (p=0.03), and OS (p<0.001 and BMI with worse OS (p=0.05). On multivariate analysis, obesity (HR=2.8; 95% CI=1.05-7.3; p=0.04) and optimal tumor debulking (HR=0.05; 95% CI=0.008-0.29; p=0.001) were a significant predictor of OS. Conclusions In a multivariate analysis, obesity and optimal tumor cytoreduction were significant predictors of OS. However, obesity was not associated with worse DSS, suggesting that mortality of obese patients with LGSC may result from other co-morbidities. Interventions addressing obesity may improve survival for women diagnosed with LGSC and further study is warranted to address the role of obesity in LGSC. PMID:24614825

    The gut microbiota has been implicated in obesity and its progression towards metabolic disease. Dietary interventions that target the gut microbiota have been suggested to improve metabolic health. The aim of the present study was to investigate the effect of interventions with Lactobacillus paracasei F19 or flaxseed mucilage on the gut microbiota and metabolic risk markers in obesity. A total of fifty-eight obese postmenopausal women were randomised to a single-blinded, parallel-group intervention of 6-week duration, with a daily intake of either L. paracasei F19 (9.4 × 1010 colony-forming units), flaxseed mucilage (10 g) or placebo. Quantitative metagenomic analysis of faecal DNA was performed to identify the changes in the gut microbiota. Diet-induced changes in metabolic markers were explored using adjusted linear regression models. The intake of flaxseed mucilage over 6 weeks led to a reduction in serum C-peptide and insulin release during an oral glucose tolerance test (P< 0.05) and improved insulin sensitivity measured by Matsuda index (P< 0.05). Comparison of gut microbiota composition at baseline and after 6 weeks of intervention with flaxseed mucilage showed alterations in abundance of thirty-three metagenomic species (P< 0.01), including decreased relative abundance of eight Faecalibacterium species. These changes in the microbiota could not explain the effect of flaxseed mucilage on insulin sensitivity. The intake of L. paracasei F19 did not modulate metabolic markers compared with placebo. In conclusion, flaxseed mucilage improves insulin sensitivity and alters the gut microbiota; however, the improvement in insulin sensitivity was not mediated by the observed changes in relative abundance of bacterial species.

    Background: Gut microbial gene richness and specific bacterial species are associated with metabolic risk markers in humans, but the impact of host physiology and dietary habits on the link between the gut microbiota and metabolic markers remain unclear. The objective of this study was to identify gut metagenomic markers associated with estimates of insulin resistance, lipid metabolism and inflammation in obesity, and to explore whether the associations between metagenomic and metabolic markers persisted after adjustment for body fat, age and habitual dietary intake. Methods: Faecal DNA from 53 women with obesity was analysed through quantitative metagenomic sequencing and analysis, and a systematic search was performed for bacterial genes associated with estimates of insulin resistance, inflammation and lipid metabolism. Subsequently, the correlations between metagenomic species and metabolic markers were tested by linear regression models, with and without covariate adjustment. Results: One hundred and fourteen metagenomic species correlated with metabolic markers (P<0.001) including Akkermansia muciniphila, Bilophila wadsworthia, Bifidobacterium longum and Faecalibacterium prausnitzii, but also species not previously associated with metabolic markers including Bacteroides faecis and Dorea longicatena. The majority of the identified correlations between bacterial species and metabolic markers persisted after adjustment for differences in body fat, age and dietary macronutrient composition; however, the negative correlation with insulin resistance observed for B. longum and F. prausnitzii appeared to be modified by the intake of dietary fibre and fat, respectively. Conclusions: This study shows that several gut bacterial species are linked to metabolic risk markers in obesity, also after adjustment for potential confounders, such as long-term diet composition. The study supports the use of gut metagenomic markers for metabolic disease prediction and warrants

    Purpose Single-variable analyses have associated physical activity, diet, and obesity with survival after breast cancer. This report investigates interactions among these variables. Patients and Methods A prospective study was performed of 1,490 women diagnosed and treated for early-stage breast cancer between 1991 and 2000. Enrollment was an average of 2 years postdiagnosis. Only seven women were lost to follow-up through December 2005. Results In univariate analysis, reduced mortality was weakly associated with higher vegetable-fruit consumption, increased physical activity, and a body mass index that was neither low weight nor obese. In a multivariate Cox model, only the combination of consuming five or more daily servings of vegetables-fruits, and accumulating 540+ metabolic equivalent tasks-min/wk (equivalent to walking 30 minutes 6 d/wk), was associated with a significant survival advantage (hazard ratio, 0.56; 95% CI, 0.31 to 0.98). The approximate 50% reduction in risk associated with these healthy lifestyle behaviors was observed in both obese and nonobese women, although fewer obese women were physically active with a healthy dietary pattern (16% v 30%). Among those who adhered to this healthy lifestyle, there was no apparent effect of obesity on survival. The effect was stronger in women who had hormone receptor–positive cancers. Conclusion A minority of breast cancer survivors follow a healthy lifestyle that includes both recommended intakes of vegetables-fruits and moderate levels of physical activity. The strong protective effect observed suggests a need for additional investigation of the effect of the combined influence of diet and physical activity on breast cancer survival. PMID:17557947

    Obesity is a prevalent health behavior that is difficult to treat because of its complexity, constraints on provider time, and negligible insurer reimbursement. In this comparative case study the authors describe two obese women's weight loss and lifestyle change efforts while enrolled in a nine-month, multidisciplinary weight loss program. The researchers conducted three semistructured interviews during six months. Eight major themes were identified: (1) support networks. (2) internalization/externalization, (3) routines, (4) relapse, (5) change in perspective, (6) reward/punishment, (7) emotional issues, and (8) life balance. These themes parallel Johnson's three-stage theory of cognitive restructuring. (See Johnson, 1990, "Restructuring: An Emerging Theory on the Process of Losing Weight." Journal of Advanced Nursing, 15, 1289-1296.) Researchers reveal that complex health problems are replete with social and psychological factors that may undermine treatment success. Understanding a client's experience while attempting behavior change is crucial for the development of interventions that address difficult and costly health behaviors. PMID:11813769

    Triglyceride content in the liver is regulated by the uptake, production and elimination of lipoproteins, and derangements in these processes contribute to nonalcoholic fatty liver disease (NAFLD). Previous studies show a direct relationship between intrahepatic fat and production of apolipoprotein B100 (apoB100) containing particles, VLDL and LDL, but little consensus exists regarding changes in lipoprotein production in the development of simple steatosis (SS) versus nonalcoholic steatohepatitis (NASH). Further, ethnic variations in lipoproteins among SS and NASH are unknown as is how such variations might contribute to the differential prevalence of disease among Caucasians versus African Americans. In this study, we assessed plasma lipoprotein profiles by nuclear magnetic resonance (NMR) spectroscopy in 70 non-diabetic class III obese females recruited from the surgical weight loss clinic. Of these, 51 females were stratified by biopsy-staged NAFLD severity (histologically normal, SS, or NASH). NASH females displayed increased circulating triglycerides and increased VLDL particle number and size relative to those with histologically normal livers, while total and large LDL concentration decreased in SS versus NASH and correlated with increased insulin resistance (via HOMA2-IR). When Caucasian women were examined alone (n = 41), VLDL and triglycerides increased between normal and SS, while total LDL and apoB100 decreased between SS and NASH along with increased insulin resistance. Compared to Caucasians with SS, African American women with SS displayed reduced triglycerides, VLDL, and small LDL and a more favorable small to large HDL ratio despite having increased BMI and HOMA2-IR. These findings suggest that ApoB100 and lipoprotein subclass particle number and size can delineate steatosis from NASH in obese Caucasian females, but should be interpreted with caution in other ethnicities as African Americans with SS display relatively improved lipoprotein profiles

    Background The goal of this study was to determine the nature and prevalence of abnormalities in lipids, glucose metabolism, and body composition in behaviorally HIV-infected young women and their relationship to different classes of antiretroviral therapy (ART) regimens. Methods We conducted a cross-sectional multicenter study in behaviorally infected women ages 12-24 years (HIVpos; N=173) and seronegative controls (HIVneg; N=61). HIVpos women were categorized as ART-naïve (N=85), on a non-nucleoside reverse transcriptase inhibitor-containing regimen (NNRTI; N=33), on a protease inhibitor-containing regimen (PI; N=36), or on a non-NNRTI/non-PI containing regimen (N=19). Measurements included fasting lipids; glucose and insulin before and 2 hours after an oral glucose challenge; high-sensitivity C-reactive protein (hsCRP); anthropometry; fat distribution (dual energy X-ray absorptiometry); and ART and medical histories. Race-adjusted results were compared across groups and within HIVpos groups. Results The median age was 20 (range 14-24) years. 77% of HIVpos were African American, 35% smoked cigarettes, and 32% reported exercising regularly. More than 40% had a BMI ≥25 kg/m2. Triglycerides; total, HDL, and non-HDL cholesterol; and hsCRP differed significantly among groups, with higher levels most common among those on ART. Indices of glucose metabolism did not differ among groups. In general, cholesterol, hsCRP, and indices of glucose metabolism worsened as BMI increased. Conclusions Obesity, dyslipidemia, and inflammation were prominent in HIV-infected adolescent women and, coupled with other risk factors, may accelerate the lifetime risk of cardiovascular disease and other adverse events. These results underscore the need for a multifaceted approach to addressing risk reduction in this population. PMID:19947855

    The relationship between the genetic background, adipocytokines, and metabolic state in postmenopausal women has not yet been fully described. The aim of this study was to determine the relationship between PPAR gamma-2 (Pro12Ala, C1431T) and ADRB3 (Trp64Arg) polymorphisms and serum adipocytokines (adiponectin, visfatin, and resistin) and metabolic disorders in 176 postmenopausal women with increased body mass (BMI ≥ 25 kg m(-2)). The distributions of selected alleles and genotype frequencies were determined with the PCR-RFLP method. The bioimpedance method was used to determine nutritional status, and enzyme-linked immunosorbent assays were applied to determine serum concentrations of adipocytokines. Viscerally obese postmenopausal women had higher body mass, body fat content, serum glucose, insulin, total cholesterol, LDL, triglycerides, uric acid, and HOMA-IR and a higher prevalence of the Ala12 allele. In models based on cytokine concentration, higher body mass and glucose concentration (visfatin model, p = 0.008) and higher insulin and triglyceride levels (resistin model, p = 0.002) were observed in visceral fat deposition and this was potentiated by the presence of the T1431 allele. In resistin models, co-existence of Ala12/X polymorphisms with the T1431 allele was associated with higher resistin and triglyceride concentrations (p = 0.045). In postmenopausal women, metabolic parameters are mainly determined by the distribution of body fat, but Ala12/X polymorphism may increase the metabolic disorders and this effect can be enhanced by the T1431 allele.

    Background/Objectives It has been suggested that the association between shift work and chronic disease is mediated by an increase in obesity. However, investigations of the relationship between shift work and obesity reveal mixed findings. Using a recently developed exposure assessment tool, this study examined the association between shift work and obesity among Canadian women from two studies: a cohort of university alumni, and a population-based study. Methods Self-administered questionnaire data were used from healthy, currently employed females in a population-based study, the Ontario Women’s Diet and Health case-control study (n = 1611 controls), and from a subset of a of university alumni from the Canadian Study of Diet, Lifestyle, and Health (n = 1097) cohort study. Overweight was defined as BMI≥25 to <30, and obesity as BMI≥30. Reported occupation was converted to occupational codes and linked to a probability of shift work value derived from Survey of Labour and Income Dynamics data. Regular evenings, nights, or rotating work comprised shift work. Polytomous logistic regression estimated the association between probability of shift work, categorized as near nil, low, medium, and high probability of shift work, on overweight and obesity, controlling for detected confounders. Results In the population-based sample, high probability of shift work was associated with obesity (reference = near nil probability of shift work, OR: 1.88, 95% CI: 1.01–3.51, p = 0.047). In the alumni cohort, no significant association was detected between shift work and overweight or obesity. Conclusions As these analyses found a positive association between high probability of shift work exposure and obesity in a population-based sample, but not in an alumni cohort, it is suggested that the relationship between shift work and obesity is complex, and may be particularly susceptible to occupational and education-related factors within a given population.

    2016-01-01

    Background Dipeptidyl peptidase 4/CD26 (DPP-4) is a widely expressed cell surface serine protease. DPP-4 inhibitors, one of common anti-diabetic agents play a protective role in bone metabolism in recent studies. A soluble form of DPP-4 is found in serum, and exhibits DPP-4 enzymatic activity. However, the physiological role of serum or soluble DPP-4 and its relationship with DPP-4 enzymatic function remain poorly understood. The aims of current study were to determine the association between serum DPP-4 activity and bone mineral density (BMD) in postmenopausal women. Methods We recruited data and serum samples from 124 consecutive healthy postmenopausal women aged >50 years. We divided study subjects into obese (body mass index [BMI] ≥25 kg/m2) and non-obese (BMI <25 kg/m2) postmenopausal women and examined the correlation between serum DPP-4 activity and clinical variables in each groups. Results A total of 124 postmenopausal women was enrolled, with a mean age of 59.9±7.1 years. The mean BMI of the study patients was 24.4±2.8 kg/m2. Regarding bone turnover markers, serum DPP-4 activity was positively correlated with serum calcium concentrations, intact parathyroid hormone, and serum C-telopeptide levels in all of the study subjects. However, there was no association between serum DPP-4 activity and BMD in the spine or femoral neck in all of the study subjects. Serum DPP-4 activity was negatively correlated (R=−0.288, P=0.038) with BMD of the spine in obese postmenopausal women. Conclusion This study demonstrated for the first time that serum soluble DPP-4 activity was negatively correlated with BMD in obese postmenopausal women. PMID:26676330

    Caraway (Carum carvi L.), a potent medicinal plant, is traditionally used for treating obesity. This study investigates the weight-lowering effects of caraway extract (CE) on physically active, overweight and obese women through a randomized, triple-blind, placebo-controlled clinical trial. Seventy overweight and obese, healthy, aerobic-trained, adult females were randomly assigned to two groups (n = 35 per group). Participants received either 30 mL/day of CE or placebo without changing their diet or physical activity. Subjects were examined at baseline and after 90 days for changes in body composition, anthropometric indices, and clinical and paraclinical variables. The treatment group, compared with placebo, showed a significant reduction of weight, body mass index, body fat percentage, and waist-to-hip ratio. No changes were observed in lipid profile, urine-specific gravity, and blood pressure of subjects. The results suggest that a dietary CE with no restriction in food intake, when combined with exercise, is of value in the management of obesity in women wishing to lower their weight, BMI, body fat percentage, and body size, with no clinical side effects. In conclusion, results of this study suggest a possible phytotherapeutic approach for caraway extract in the management of obesity. This trial is registered with NCT01833377. PMID:24319489

    Introduction. Obesity is a condition that causes damage to the respiratory function. However, studies have demonstrated that weight loss due to bariatric surgery has resulted in a huge improvement on some lung volumes, but controversy still persists regarding the behavior of the respiratory muscle strength and IRV (inspiratory reserve volume). Objective. To evaluate the effect of weight loss, after 1 year of the Roux-en-Y gastric bypass surgery (RYGB), on the lung volumes and the respiratory muscle strength in obese women. Methods. 24 obese women candidates were recruited for RYGB. Lung volumes (spirometry) and respiratory muscle strength were evaluated in preoperative period and one year after surgery. Results. There was a significant increase in some lung volumes. However, when examining the components of the VC (vital capacity) separately, an increase in ERV (expiratory reserve volume) and reduction of IRV were observed. Moreover, a statistically significant reduction in the values of respiratory muscle strength was recorded: MIP (maximal inspiratory pressure) and MEP (maximal expiratory pressure). Conclusion. Weight loss induced by bariatric surgery provides an increase in some lung volumes of obese women, but reduction in IRV. Additionally, there was also a reduction in the respiratory muscle strength.

    Household food insecurity (HFI) may increase obesity risk, but results are not consistent across the life course or between developed/underdeveloped settings. The objective of this paper is to review findings from previous analyses in Brazil among adult women, female adolescents, and children up to five. Data were derived from the 2006 Brazilian Demographic and Health Survey. Associations between HFI (measured with the Brazilian Food Insecurity Scale) and excess weight/obesity were investigated through Poisson regression models. While severe HFI was associated with obesity risk among adult women (PR: 1.49; 95%CI: 1.17-1.90), moderate HFI was associated with excess weight among female adolescents (PR: 1.96; 95%CI: 1.18-3.27). There was no association between HFI and obesity among children (either boys or girls). The nutrition transition in Brazil may be shaping the differential deleterious effect of HFI on body fat accumulation across the life course; the association is already evident among female adolescents and adult women but still not among children.

    Background Nutritional research in sub-Saharan Africa has primarily focused on under-nutrition. However, there is evidence of an ongoing nutritional transition in these settings. This study aimed to examine the geographic variation of overweight and obesity prevalence at the state-level among women in Nigeria, while accounting for individual-level risk factors. Methods The analysis was based on the 2008 Nigerian Demographic and Health Survey (NDHS), including 27,967 women aged 15–49 years. Individual data were collected on socio-demographics, but were aggregated to the country's states. We used a Bayesian geo-additive mixed model to map the geographic distribution of overweight and obesity at the state-level, accounting for individual-level risk factors. Results The overall prevalence of combined overweight and obesity (body mass index ≥25) was 20.9%. In multivariate Bayesian geo-additive models, higher education [odds ratio (OR) & 95% Credible Region (CR): 1.68 (1.38, 2.00)], higher wealth index [3.45 (2.98, 4.05)], living in urban settings [1.24 (1.14, 1.36)] and increasing age were all significantly associated with a higher prevalence of overweight/obesity. There was also a striking variation in overweight/obesity prevalence across ethnic groups and state of residence, the highest being in Cross River State, in south-eastern Nigeria [2.32 (1.62, 3.40)], the lowest in Osun State in south-western Nigeria [0.48 (0.36, 0.61)]. Conclusions This study suggests distinct geographic patterns in the combined prevalence of overweight and obesity among Nigerian women, as well as the role of demographic, socio-economic and environmental factors in the ongoing nutritional transition in these settings.

    Background Non-alcoholic fatty liver disease (NAFLD) causes a wide spectrum of liver damage, ranging from simple steatosis to cirrhosis. However, simple steatosis (SS) and steatohepatitis (NASH) cannot yet be distinguished by clinical or laboratory features. The aim of this study was to assess the relationship between alpha-ketoglutarate and the degrees of NAFLD in morbidly obese patients. Materials and Methods We used a gas chromatography-quadruple time-of-flight-mass spectrometry analysis to quantify alpha-ketoglutarate in serum from normal-weight subjects (n = 30) and morbidly obese women (n = 97) with or without NAFLD. Results We found that serum levels of alpha-ketoglutarate were significantly higher in morbidly obese women than in normal-weight women. We showed that circulating levels of alpha-ketoglutarate were lower in lean controls and morbidly obese patients without NAFLD. We also found that alpha-ketoglutarate serum levels were higher in both SS and NASH than in normal liver of morbidly obese patients. However, there was no difference between SS and NASH. Moreover, we observed that circulating levels of alpha-ketoglutarate were associated with glucose metabolism parameters, lipid profile, hepatic enzymes and steatosis degree. In addition, diagnostic performance of alpha-ketoglutarate has been analyzed in NAFLD patients. The AUROC curves from patients with liver steatosis exhibited an acceptable clinical utility. Finally, we showed that the combination of biomarkers (AST, ALT and alpha-ketoglutarate) had the highest accuracy in diagnosing liver steatosis. Conclusion These findings suggest that alpha-ketoglutarate can determine the presence of non-alcoholic fatty liver in morbidly obese patients but it is not valid a biomarker for NASH. PMID:27123846

    AIM(S) While it is known that CYP3A4/5 activity is decreased with combined oral contraceptive (COC) use and obesity suppresses CYP expression, the combined effects of obesity and COC use on CYP3A4/5 activity are unclear. Therefore, our aim was to examine the effect of COC usage on CYP3A4/5 activity in obese women. METHODS Thirty-four, obese (body mass index, BMI > 30 kg m−2) women of reproductive age (18–35 years old) were placed on a COC pill containing 20 µg ethinylestradiol/100 µg levonorgestrel for 21 days starting at the onset of menses. A midazolam pharmacokinetic study was conducted prior to initiation and after 21 days of COC treatment. Serial blood samples were collected and plasma concentrations of midazolam were measured using liquid chromatography tandem mass spectrometry. Pharmacokinetic parameters were estimated using a non-compartmental method. RESULTS Midazolam clearance, a surrogate measure of CYP3A4/5 activity, was significantly decreased upon COC use (63.3 l h−1vs. 53.9 l h−1, P < 0.05). A median decrease of 5.6 l h−1 (95% CI −4.1, 13.3 l h−1) was observed. However, the magnitude of change was similar to that reported in women with normal BMI. CONCLUSIONS Although we hypothesized that obesity might amplify the impact on CYP3A4/5 activity in COC users, we found that this was not the case. This finding is reassuring regarding potential additional drug−drug interactions in obese COC users as CYP3A4/5 is a major enzyme in the metabolism of many marketed drugs. PMID:22299599

    The purpose of this study was to examine the association between sarcopenia and sarcopenic obesity (SO) with cardiometabolic risk factors in postmenopausal women. 149 volunteers (67.17±6.12 years) underwent body composition assessment using dual energy X-ray absorptiometry (DXA) and had analyzed blood samples collected for lipid profile, glucose metabolism and C-reactive protein (CRP). Sarcopenia was defined as an appendicular fat-free mass (AFFM) divided by height squared ≤5.45 kg/m(2) while SO was classified based on the residuals of a regression. Waist circumference (WC) and arterial blood pressure were also measured. Student's t-tests and correlations were used for analyses. Prevalence of sarcopenia and SO were respectively 16.8 and 21.5%. WC was significantly correlated with all the examined risk factors. AFFM relative to height squared was positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP), CRP, insulinaemia, HOMA score, and those classified as sarcopenic presented lower HOMA score when compared to nonsarcopenic. Regarding SO, although volunteers classified presented significantly higher fat mass (FM) and lower AFFM, it was not observed association with the examined risk factors. These findings support the association between WC and cardiometabolic risk factors in older women. In contrast, the approaches used to define sarcopenia and SO are not associated with cardiometabolic impairments. PMID:24766993

    In obese women (n = 16) at their weight, fasting adipose tissue lipoprotein lipase (LPL) activity, obtained by elution with serum and heparin at 4 degrees and 37 degrees C, was inversely correlated to plasma estradiol levels (r = -0.724; P = 0.002) and (r = -0.641; P = 0.010), respectively. Furthermore, fasting postheparin plasma LPL activity during a heparin infusion, showed an even stronger inverse correlation to plasma estradiol when measured at 60 min (r = -0.815; P less than 0.001). None of the above parameters was correlated to the body mass index. Postprandial LPL activity in postheparin plasma, measured 10 min after a heparin injection, showed a strong positive correlation with plasma free testosterone (r = 0.780; P = 0.001). Neither of these parameters was correlated with the body mass index. The origin of this LPL activity is presently unknown but could conceivably represent a pool of LPL from skeletal muscle. Since it has been shown convincingly that estrogen decreases adipose tissue LPL activity in the rat, the present studies strongly suggest that estradiol is a major negative regulator of fasting adipose tissue LPL activity in women.

    We examined the effects of variations in postprandial glycemia and insulinemia on subjective satiety in overweight and obese women. We altered the ingestion rate of a glucose beverage to model the postprandial effects of high- and low-glycemic meals. Fourteen women were tested in a within-subjects' design with two conditions: (1) Rapid, with a large glucose beverage consumed with breakfast and lunch and (2) Slow, with the same volume of glucose beverage consumed in eight portions (one with each meal, and the remaining seven at 20-min intervals after each meal). Meals were identical in the two conditions. Subjective appetitive sensations were measured with visual analog scales before and after meals, and hourly after each meal until 5 pm. Serum glucose and insulin were measured at similar time points. Subjects reported higher ratings of hunger and prospective consumption in the Rapid versus Slow condition at 4h after breakfast and several hours after lunch. Serum glucose was more strongly correlated with the appetitive ratings in the Rapid than the Slow condition, and explained more of the variance (20-31%) than insulin (2-4%). The results of this study support the glucostatic theory linking dynamic changes in blood glucose with appetitive sensations. PMID:17714828

    Abstract Background: Cardiovascular disease (CVD) is a leading cause of preventable death among young women in the United States. Habitual resistance exercise training is known to have beneficial effects on endothelial function and CVD risk factors, including obesity; however, previous studies show that acute resistance exercise impairs endothelial function in obese adults who are sedentary, a response that may be linked to inflammation. We sought to determine if circuit-based resistance training (CRT) attenuates acute resistance exercise-induced reductions in endothelial function in a population of young, obese, sedentary women and whether or not inflammation plays a role in this response. Methods: Eighteen obese [body mass index (BMI) 30.0–40.0 kg·m−2] young premenopausal women were randomly assigned to either a CRT group or a no-exercise control group (CON). Conduit artery endothelial function was assessed using brachial artery flow-mediated dilation (FMD) determined by ultrasound before and after a single bout of strenuous weightlifting (SWL). In addition, circulating inflammatory mediators (tumor necrosis factor-α and C-reactive protein), blood pressure, fasting blood lipids, glucose, waist circumference, body composition, and aerobic capacity were assessed. Results: Among participants randomized to the CRT group, 8 weeks of training led to considerable increases in FMD after SWL (P=0.001) compared to the CON group. However, no significant differences between the groups were observed in circulating inflammatory mediators, blood pressure, fasting blood lipids, or other physical and physiological characteristics. Conclusions: This study shows that CRT alleviates acute exertion-induced reductions in endothelial function among obese sedentary women in the absence of changes in inflammation. PMID:25844686

    Afternoon snacking contributes significantly to total energy intake. Strategies to enhance the satiety value of lunch and reduce afternoon snacking are of interest for body weight management. To assess whether between-meal gum chewing would enhance the satiety response to a fixed lunch meal; and assess the role of cholecystokinin (CCK) as a potential mediator of the response in non-obese healthy weight and obese women. Fifty unrestrained obese (n=25) and non-obese healthy weight (n=25) women participated in a two-arm cross-over study assessing multiple (15min per hour×3h) gum chewing (GUM) occurrences or no gum (Control) on subjective ratings of satiety, subsequent sweet and salty snack intake, CCK and general metabolic responses. GUM compared to Control resulted in significant suppression of hunger, desire to eat and prospective consumption (p<0.05). Total snack energy intake was reduced ~9.3% by GUM, but not significantly different from Control (p=0.08). However, overall carbohydrate intake was reduced by GUM (p=0.03). This was consistent with a reduction in snacks characterized as high carbohydrate, low fat (p=0.02). BMI specific effects indicated GUM reduced pretzel intake in obese women (p=0.05) and Oreo cookie intake in healthy weight women (p=0.03) 3h after lunch. Metabolic responses and CCK did not differ between experimental conditions. Chewing gum intermittently post-lunch enhances perceptions of satiety and may have important implications in reducing afternoon high carbohydrate-snack intake. PMID:26948161

  1. Validation of obesity based on self-reported data in Spanish women participants in breast cancer screening programmes

    2011-01-01

    Background Measurement of obesity using self-reported anthropometric data usually involves underestimation of weight and/or overestimation of height. The dual aim of this study was, first, to ascertain and assess the validity of new cut-off points, for both overweight and obesity, using self-reported Body Mass Index furnished by women participants in breast cancer screening programmes, and second, to estimate and validate a predictive model that allows recalculate individual BMI based on self-reported data. Methods The study covered 2927 women enrolled at 7 breast cancer screening centres. At each centre, women were randomly selected in 2 samples, in a ratio of 2:1. The larger sample (n = 1951) was used to compare the values of measured and self-reported weight and height, to ascertain new overweight and obesity cut-off points with self-reported data, using ROC curves, and to estimate a predictive model of real BMI using a regression model. The second sample (n = 976) was used to validate the proposed cut-off points and the predictive model. Results Whereas reported prevalence of obesity was 19.8%, measured prevalence was 28.2%. The sensitivity and specificity of this classification would be maximised if the new cut-off points were 24.30 kg/m2 for overweight and 28.39 kg/m2 for obesity. The probability of classifying women correctly in their real weight categories on the basis of these points was 82.5% in the validation sample. Sensitivity and specificity for determining obesity using the new cut-off point in the validation sample were 90.0% and 92.3% respectively. The predictive model for real BMI included the self-reported BMI, age and educational level (university studies vs lower levels of education). This model succeeded in correctly classifying 90.5% of women according to BMI categories, but its performance was similar to that obtained with the new cut-off points. Conclusions Quantification of self-reported obesity entails a considerable underestimation of

    Obesity may influence fibromyalgia severity. The present study aimed to examine fibromyalgia (FM) symptomatology, quality of life (QoL), and functional capacity across obesity class categories. A total sample of 208 obese FM patients and 108 obese control women were included in the study. The sample was further categorized following the international criteria for obesity classes: obesity I (BMI 30.0-34.99 kg/m(2)), obesity II (BMI 35.0-39.99 kg/m(2)), and obesity III (BMI ≥40.0 kg/m(2)). QoL was assessed by means of the Short-Form-36 Health Survey (SF-36) and FM symptomatology with the Fibromyalgia Impact Questionnaire (FIQ). Standardized field-based fitness tests were used to assess cardiorespiratory fitness, muscular strength, flexibility, agility, and balance. All the dimensions of QoL, as measured by SF-36, were worse in obese FM patients compared to the obese control group (all p < 0.001). Obese FM patients also scored worse in the entire functional capacity tests studied (all p < 0.001). Except for the higher FIQ-depression across obesity status categories (p < 0.05), no differences between obesity status groups were found in QoL and FM impact. However, upper-body muscular strength and cardiorespiratory fitness were worse across obesity class categories and pairwise comparisons showed differences mainly between obesity I and II (p < 0.05, and p < 0.01, respectively). The absence of clear differences in QoL and FM symptomatology among obesity classes suggests that just avoiding any obese status may be a useful advice for a better management of the disease. Nevertheless, upper-body muscular strength and cardiorespiratory fitness, which are important health indicators highly related to the mortality risk, were worse across obesity categories.

    The objective of the study was to examine the effects of a 16-week walking program on food group preferences and energy balance of sedentary, moderately obese (body mass index, 29-35 kg/m(2)), postmenopausal Caucasian women, aged 60 ± 5 years old. One hundred and fifty-six volunteers were subjected to 3 sessions/week of 45 min of walking at 60% of heart rate reserve. Total energy intake (TEI) and food group preferences (3-day dietary record), total energy expenditure (TEE, 3-day physical activity diary), cardiorespiratory fitness (2-km walking test), anthropometry, and body composition (bioelectrical impedance) were measured before and after walking. Data were statistically analyzed using an ANOVA with repeated measures on 1 factor (time). The modest increase in TEE of 151 ± 24 kcal/day (p < 0.0001) leads to body weight, fat mass losses, and waist girth reduction (p < 0.0001). TEI remained unchanged despite a slight decrease in carbohydrate intake and a minor increase in protein intake (p < 0.05). Analysis of food records revealed a decreased consumption of fruits (p < 0.05) and sweet and fatty foods (p < 0.01), but an increase in oil consumption (p < 0.0001) after walking. Women with the highest body weight loss showed the greatest reduction in the consumption of fruits, sugar, sweet foods, and fatty foods (p < 0.05). Women with the greatest fat mass loss showed the highest decrease in fatty food intake (p < 0.05). In conclusion, although our walking program changed some food group consumption patterns, body weight loss was primarily because of the increased TEE. PMID:26140417

    This study tested the independent and interactive effects of anxiety and dietary restraint on the relative reinforcing value of snack food. Thirty non-obese, female university students were assigned to one of four groups based on median split scores on measures of dietary restraint and state-anxiety: low-restraint/low-anxiety (n=7), low-restraint/high-anxiety (n=7), high-restraint/low-anxiety (n=9), and high-restraint/high-anxiety (n=7). Participants were provided the choice to earn points for palatable snack foods or fruits and vegetables using a computerized concurrent schedules choice task. The behavioural cost to gain access to snack foods increased across trials, whereas the cost to gain access to fruits and vegetables was held constant across trials. The relative reinforcing value of palatable snack food in relation to fruits and vegetables was defined as the total amount of points earned for snack food. Two-way analysis of covariance, with hunger and hedonic snack food ratings as covariates, showed that dietary restraint and anxiety had a significant interactive effect on the relative reinforcing value of snack food, indicating that the effect of anxiety on snack food reinforcement is moderated by dietary restraint. Specifically, the high-anxiety/low-restraint women found snack food significantly less reinforcing than low-anxiety/low-restraint women, but no differences emerged between high- and low-anxiety women with high-restraint. Neither restraint nor anxiety had an independent effect on the relative reinforcing value of snack food. These findings indicate that anxiety may have a suppressive effect on the relative reinforcing value of snack food in low-restrained eaters, but not an enhancing effect on snack food reinforcement in high-restrained eaters. Clinical implications of these findings are discussed. PMID:17056408

    Objective To evaluate inadequate gestational weight gain and fetal growth among overweight and obese women (O/O). Study Design Analysis of prospective singleton term pregnancies in which 1053 O/O gained greater (14.4± 6.2 kg) or 188 who either lost or gained ≤5 kg (1.1± 4.4 kg). Birth weight, fat (FM) and lean mass (LM) were assessed using anthropometry. Small for gestational age (SGA) was defined as ≤ 10th percentile of a standard US population. Univariable and multivariable analysis evaluated the association between weight change and neonatal morphometry. Results There was no significant difference in age, race, smoking, parity, or gestational age between groups. Weight loss or gain ≤ 5 kg was associated with SGA, 18/188 (9.6%) vs. 51/1053 (4.9%); (adjusted OR 2.6, 95% CI 1.4, 4.7; p=0.003). Neonates of women who lost or gained ≤ 5 kg had lower birth weight (3258 ± 443 g vs. 3467 ± 492g, p<0.0001), FM (403±175 vs. 471 ± 193g, p<0.0001), LM (2855±321 vs. 2995 ± 347g, p<0.0001) and smaller length, %FM and head circumference (HC). Adjusting for diabetic status, pre-pregnancy BMI, smoking, parity, study site, gestational age and gender; neonates of women who gained ≤ 5 kg had significantly lower birth weight, LBM, FM, %FM, HC and length. There were no significant differences in neonatal outcomes between those who lost weight and those who gained ≤ 5 kg. Conclusion In O/O weight loss or gain ≤ 5 kg is associated with increased risk of SGA and decreased neonatal FM, LM and HC. PMID:24530820

    Objective Elevated inflammation biomarkers are associated with incident cardiovascular disease. Several studies suggest that childhood abuse may be associated with inflammation later in life. This study examined whether childhood abuse predicted elevated levels of C reactive protein (CRP) and whether the association was due to body size. Methods Participants were 326 (104 Black, 222 White) women from the Pittsburgh site of the Study of Women’s Health Across the Nation (SWAN). SWAN included a baseline assessment of premenopausal or early perimenopausal women in midlife (mean age = 45.7), and CRP, depressive symptoms, body mass index (BMI), and other covariates were measured over 7 annual follow-up visits. The Childhood Trauma Questionnaire, a standardized measure that retrospectively assesses abuse and neglect in childhood and adolescence, was administered at year 8 or 9 of follow-up. Results Approximately 37% of the participants reported a history of abuse or neglect. Generalized estimating equations showed that sexual and emotional abuse, emotional and physical neglect, and the total number of types of abuse were associated with higher CRP levels over 7 years, adjusting for race, age, education, smoking status, use of hormone therapy, depressive symptoms, occurrence of heart attack or stroke, and medications for hypertension. The coefficients for indirect effects for emotional and sexual abuse, physical neglect, and total number of types of abuse on CRP levels through BMI were significant. A history of emotional abuse and neglect was related to percent change in CRP over the 7 years but not through percent change in BMI over the 7 years. Conclusion A history of childhood abuse and neglect retrospectively reported is related to overall elevated inflammation in mid-life women, perhaps through obesity. A history of some types of abuse and neglect (emotional) may be related to change in inflammation, independent of simultaneously measured change in BMI. PMID

    One exercise training session such as walking, running, and resistance can lead to a decrease in blood pressure in normotensive and hypertensive individuals, but few studies have investigated the effects of exercise training in an aquatic environment for overweight and obese hypertensive individuals. We aimed to assess the acute effects of a water aerobics session on blood pressure changes in pharmacologically treated overweight and obese hypertensive women. A randomized crossover study was carried out with 18 hypertensive women, 10 of them were overweight (54.4 ± 7.9 years; body mass index: 27.8 ± 1.7 kg/m(2)) and eight obese (56.4 ± 6.6 years; body mass index: 33.0 ± 2.0 kg/m(2)). The water aerobics exercise session consisted of a 45-minute training at the intensity of 70%-75% of maximum heart rate adjusted for the aquatic environment. The control group did not enter the pool and did not perform any exercise. We measured systolic blood pressure (SBP) and diastolic blood pressure (DBP) before, immediately after, and every 10 minutes up to 30 minutes after the aerobic exercise or control session. Overall (n = 18), DBP did not change after the water aerobic exercise and control session, and SBP decreased at 10 and 20 minutes postexercise compared to the control session. Among overweight women, SBP decreased at 10 and 20 minutes postexercise. In contrast, among obese women, SBP decreased only at 10 minutes postexercise. SBP variation was -2.68 mm Hg in overweight and -1.24 mm Hg in obese women. In conclusion, the water aerobics session leads to a reduction in SBP, but not in DBP, during 10 and 20 minutes postexercise recovery. Thus, it may be safely prescribed to overweight and obese women.

    Overweight/obesity and depression are common among women especially in the elderly and can lead to unfavorable outcomes. We aimed to determine the association of overweight with depression and also to find any correlation of depression with some anthropometric indices in old women. A total of 94 depressed elderly women were compared with 99 non-depressed controls. The structured diagnostic interview based on DSM-IV were performed to diagnose depression, and Geriatric Depression Scale (GDS) was completed to rate it. Anthropometric indices were measured and compared between groups. Pearson correlation coefficients were determined for linear relations between variables. Odds Ratio of obesity and overweight in depressed subjects comparing with normal participants was 1.45 (95%CI=0.63-3.32). A significant correlation was observed between BMI and GDS score (r=0.231, P-value=0.001). Total body fat (P-value=0.001) and BMI (P-value=0.016) were significantly higher in depressed women than non-depressed women. Despite the significantly higher total body fat and BMI among old women with depression, only a weak correlation was seen between BMI and GDS score. PMID:26786989

    With the increasing number of overweight and obese people, there is a growing public health concern and focus on body size and lifestyle issues, especially in the media. Young adult women comprise a vulnerable group regarding issues of weight balance and appearance. The aim of the study was to examine the experiences of young women on how this focus influences their attitudes concerning weight changes, appearance, and health. We conducted 12 interviews with young women from two different weight groups about the attention on overweight issues. The results from the in-depth interviews were scrutinized through content analyses. The main findings indicate that young women experience a considerable focus on overweight issues with a trend towards appearance rather than health. Overweight and obesity are sensitive topics, and participants expressed strong views on the cultural definitions of normal body size and appearance. The squeeze between cultural norms and young women's perceptions of their own body and health was described as a possible negative factor influencing well-being as well as motivation for lifestyle changes. A more relaxed focus on overweight issues and especially on appearance is necessary when addressing weight-balance issues and lifestyle changes in young adult women. PMID:26400463

    Objective To investigate adverse pregnancy outcomes in non-obese women with polycystic ovary syndrome (PCOS) compared with obese-PCOS and control groups. Methods Women with PCOS who underwent assisted reproductive technology (ART) from August, 2003 to December, 2007, were considered. A total of 336 women with PCOS were included in the study group and 1,003 infertile women who had tubal factor as an indication for ART were collected as controls. They were divided into four groups: a non-obese PCOS group, obese-PCOS group, non-obese tubal factor group, and obese tubal factor group, with obesity defined by a body mass index over 25 kg/m2, and reviewed focusing on the basal characteristics, ART outcomes, and adverse pregnancy outcomes. Results There was no difference among the groups' the clinical pregnancy rate or live birth rate. Regarding adverse pregnancy outcomes, the miscarriage rate, multiple pregnancy rate, and prevalence of preterm delivery and pregnancy induced hypertension were not different among the four groups. The incidence of small for gestational age infant was higher in the PCOS groups than the tubal factor groups (p<0.02). On the other hand, the morbidity of gestational diabetes mellitus (GDM) was not high in the non-obese PCOS group but was in the obese groups. And in the obese PCOS group, the newborns were heavier than in the other groups (p<0.02). Conclusion Non-obese PCOS presents many differences compared with obese PCOS, not only in the IVF-parameters but also in the morbidity of adverse pregnancy outcomes, especially in GDM and fetal macrosomia.

In cross-sectional analyses of 699 normal weight and 1294 overweight/obese postmenopausal women enrolled in a nested case-control stroke study ancillary to the Women’s Health Initiative Observational Study, we compared levels of adiponectin, leptin, and resistin among metabolically benign normal weight, at-risk normal weight, metabolically benign obese, and at-risk obese women using components of the ATP III definition of the metabolic syndrome (metabolically benign: ≤1 of the 4 components; at-risk phenotype: ≥2 components or diabetes). Overall, 382/699 normal weight women (54.6%) and 328/1194 overweight/obese women (27.5%) were metabolically benign. Among normal weight women, at-risk women had higher leptin and lower adiponectin levels compared to metabolically benign women; multivariate-adjusted odds ratios were significant for having leptin (OR: 2.51; 95% CI: 1.28–5.01) and resistin (1.46; 1.03–2.07) in the top tertile and adiponectin in the bottom tertile (2.64; 1.81–3.84). Compared to metabolically benign overweight/obese women, at-risk obese women had higher odds of having leptin in the top tertile (1.62; 1.24–2.12) and adiponectin in the bottom tertile (2.78; 2.04–3.77). Overall, metabolically benign overweight/obese women had an intermediate adipokine profile (between at-risk obese and metabolically benign normal weight women), while at-risk normal weight women had a less favorable profile compared to metabolically benign normal weight women. As adiponectin was the only adipokine independent of BMI, it may be most likely to have a role in the etiological pathway of these phenotypes. PMID:24357553

    Among all fruits, berries have shown substantial cardio-protective benefits due to their high polyphenol content. However, investigation of their efficacy in improving features of metabolic syndrome and related cardiovascular risk factors in obesity is limited. We examined the effects of blueberry supplementation on features of metabolic syndrome, lipid peroxidation, and inflammation in obese men and women. Forty-eight participants with metabolic syndrome [4 males and 44 females; BMI: 37.8 ± 2.3 kg/m2; age: 50.0 ± 3.0 y (mean ± SE)] consumed freeze-dried blueberry beverage (50 g freeze-dried blueberries, #126 350 g fresh blueberries) or equivalent amounts of fluids (controls, 960 mL water) daily for 8 wk in a randomized controlled trial. Anthropometric and blood pressure measurements, assessment of dietary intakes, and fasting blood draws were conducted at screening and at wk 4 and 8 of the study. The decreases in systolic and diastolic blood pressures were greater in the blueberry-supplemented group (− 6 and − 4%, respectively) than in controls (− 1.5 and − 1.2%) (P lt 0.05), whereas the serum glucose concentration and lipid profiles were not affected. The decreases in plasma oxidized LDL and serum malondialdehyde and hydroxynonenal concentrations were greater in the blueberry group (− 28 and − 17%, respectively) than in the control group (− 9 and − 9%) (P lt 0.01). Our study shows blueberries may improve selected features of metabolic syndrome and related cardiovascular risk factors at dietary achievable doses. PMID:20660279

    According to systemic-constructivist theory, all psycho-pathological organizations are linked to specific meanings which are developed by the individual within problematic situations in the context of learning, particularly within the family. The aim of this empirical study is to support the theory that eating disorders are linked to the “power semantics,” concept developed by Ugazio. The hypothesis that the bipolar construct “winner/loser” and the associated meanings are predominant for obese people, has been verified by interviewing 44 women (22 obese/overweight; 22 controls) using the Repertory Grid Test developed by Kelly. The participants’ elicited constructs were classified according to their semantic content and the data compared using statistical techniques. The power semantics were more prevalent and important in the Obese Group than in the Control Group. These results are critically discussed, highlighting possible clinical developments. PMID:23267334

    Obese patients have decreased fasting and postprandial levels of peptide YY (PYY), an anorexigenic peptide produced by the L cells of the gastrointestinal mucosa. Fatty nutrients are the most powerful stimulus for PYY release. Cholestyramine, an anion exchanger which adsorbs bile salts, reduces digestion of lipids. The aim of the present study was to investigate the effects of cholestyramine or placebo on PYY secretion in obese women administered a high-fat meal [n=8; age: 30.9±2.7 years; BMI: 47.3±3.3 kg/m2]. Postprandial PYY levels in obese women given placebo significantly increased in plasma at 30, 60, 90, and 120 min after meal ingestion. Cholestyramine administration significantly reduced postprandial PYY response at 15, 30, and 60 min. Percent fat mass (FM%) was negatively correlated with the percent increment of plasma PYY concentrations induced by meal administration at 30 min; conversely, there was a positive correlation between FM% and the percent decrement of plasma PYY concentrations induced by cholestyramine at the same time interval. These correlations failed to reach statistical significance when related to BMI. This study implies that in the obese state the altered PYY response to food consumption is a consequence of a dysfunction of L cells, which become less sensitive to the positive feedback effect of lipids.

    Childhood trauma (CT) is considered a major risk factor for several disorders as well as for the development of eating psychopathology and adult obesity. The main aims of the present study were to assess in overweight and obese women: (i) the independent association between CT and food addiction (FA), and (ii) CT in patients with both FA and clinical-level of binge eating (BE), versus patients who only engage in FA or BE. Participants were 301 overweight and obese women seeking low-energy-diet therapy. All of the patients were administered self-report measures investigating FA, BE, CT, anxiety and depressive symptoms. CT severity was moderately and positively associated with both FA (r=0.37; p<0.001) and BE (r=0.36; p<0.001) severity. The association between FA and CT remained significant after controlling for potential confounding variables. Furthermore, compared to patients without dysfunctional eating patterns, the co-occurrence of FA and BE was associated with more severe CT as well as with more severe psychopathology (i.e., anxiety and depressive symptoms) and higher BMI. Our results suggest that clinicians should carefully assess the presence of CT in individuals who report dysfunctional eating patterns in order to develop treatment approaches specifically for obese and overweight patients with a history of CT.

    Obesity at diagnosis of breast cancer is associated with higher all-cause mortality and treatment-associated toxicities. We evaluated the association between parity and obesity in the Ella study, a population of Mexican and Mexican–American breast cancer patients with high parity. Obesity outcomes included body mass index (BMI) ≥30 kg/m2, waist circumference (WC) ≥35 in (88 cm), and waist-to-hip-ratio (WHR) ≥0.85. Prevalence of obesity ([BMI] ≥30 kg/m2) was 38.9 %. For WC, the multivariate odds ratio (OR) (95 % confidence interval [CI]) for having WC ≥ 35 inches in women with ≥4 pregnancies relative to those with 1–2 pregnancies was 1.59 (1.01–2.47). Higher parity (≥4 pregnancies) was non-significantly associated with high BMI (OR = 1.10; 95 % CI 0.73–1.67). No positive association was observed for WHR. Our results suggest WC is independently associated with high parity in Hispanic women and may be an optimal target for post-partum weight loss interventions. PMID:22618357

    Physical activity (PA) is suggested to increase the peak bone mass and to minimize age-related bone loss, and thereby to reduce the risk of osteoporosis. However, the relation between PA and bone health considering the obesity status is unclear so far. The present study examines the association between PA levels and calcaneal broadband ultrasound attenuation (BUA), particularly under consideration of obesity. Data from a population-based sample of 6776 German women from the EPIC-Potsdam cohort were analyzed. Calibrated PA data were used. Statistical analyses were stratified by menopausal and obesity status. Multiple linear regression was used to model the relationship between PA and BUA levels after adjustment for age, body mass index (BMI), smoking status, education, alcohol and calcium intake, and hormone use. Peri-/premenopausal had higher BUA levels (112.39 ± 10.05 dB/MHz) compared to postmenopausal women (106.44 ± 9.95 dB/MHz). In both groups, BUA levels were higher in the fourth compared to the lowest quartile of PA (p for trend < 0.05). In women with BMI < 30, but not BMI ≥ 30 kg/m(2), PA remained positively associated with BUA levels (p for interaction = 0.03). However, when waist circumference higher than 88 cm or body fat percentage (BF%) measures above the median were used to define obesity, a significant positive relationship was also observed in women with BMI < 30 kg/m(2) but with higher waist circumference or BF%. In conclusion, our results strengthen the hypothesis that PA has a positive influence on BUA levels, though dependent on weight. PMID:26108649

    Objective Low levels of IGF-binding protein 1 (IGFBP1) are associated with metabolic syndrome and predict diabetes development in men. The aim of this study was to determine the levels of IGFBP1 in women who later develop diabetes, in relation to abdominal obesity, and to compare these levels with those of men. Methods IGFBP1 levels were determined at baseline and after 8 years in a case–control, prospective study of Swedish women aged 35–56 years. Individuals with normal oral glucose tolerance test (OGTT) who developed abnormal glucose regulation (n=240) were pair matched to controls for age and family history of diabetes and also compared to men of the same age (n=355). Results Low fasting IGFBP1 and increased waist measurement predicted development of diabetes in women (n=60; odds ratio (OR) 70, 95% confidence interval (CI) 8–661, lowest tertile and OR 27, 95% CI 5–141, highest tertile). In women developing diabetes, baseline IGFBP1 levels were lower than expected for fasting insulin values, were associated with impaired suppression after OGTT and increased during 8 years despite an increase in fasting insulin. All individuals in the highest tertile for waist and with ≤40% suppression of IGFBP1 developed diabetes within 8 years. Circulating IGFBP1 concentrations were higher in women compared to men. Women and men who developed diabetes had a similar degree of abdominal obesity, corrected for height. Conclusions We conclude that low IGFBP1 and elevated waist measurement predict diabetes development and that IGFBP1 production is suppressed by a novel factor(s) in women developing diabetes. Increasing levels of IGFBP1 during the emergence of diabetes in men and women suggest the emergence of hepatic insulin resistance. PMID:20508082

    This study was conducted to examine the effects of combined exercise on health-related fitness, endotoxin concentrations, and immune functions of postmenopausal women with abdominal obesity. 20 voluntary participants were recruited and they were randomly allocated to the combined exercise group (n = 10) or the control group (n = 10). Visceral obesity was defined as a visceral-to-subcutaneous fat ratio ≥0.4 based on computed tomography (CT) results. Body composition, exercise stress testing, fitness measurement, CT scan, and blood variables were analyzed to elucidate the effects of combined exercise. The SPSS Statistics 18.0 program was used to calculate means and standard deviations for all variables. Significant differences between the exercise group and control group were determined with 2-way ANOVA and paired t-tests. The exercise group's abdominal obesity was mitigated due to visceral fat reduction; grip strength, push-ups, and oxygen uptake per weight improved; and HDL-C and IgA level also increased, while TNF-α, CD14, and endotoxin levels decreased. Lowered TNF-α after exercise might have an important role in the obesity reduction. Therefore, we can conclude that combined exercise is effective in mitigating abdominal obesity, preventing metabolic diseases, and enhancing immune function. PMID:26075288

    Background: Sensory properties of foods promote and guide consumption in hunger states, whereas satiation should dampen the sensory activation of ingestive behaviors. Such activation may be disordered in obese individuals. Objective: Using functional magnetic resonance imaging (fMRI), we studied regional brain responses to food odor stimulation in the sated state in obese and normal-weight individuals targeting ventral frontal regions known to be involved in coding for stimulus reward value. Design: Forty-eight women (25 normal weight; 23 obese) participated in a 2-day (fed compared with fasting) fMRI study while smelling odors of 2 foods and an inedible, nonfood object. Analyses were conducted to permit an examination of both general and sensory-specific satiation (satiation effects specific to a given food). Results: Normal-weight subjects showed significant blood oxygen level–dependent responses in the ventromedial prefrontal cortex (vmPFC) to food aromas compared with responses induced by the odor of an inedible object. Normal-weight subjects also showed general (but not sensory-specific) satiation effects in both the vmPFC and orbitofrontal cortex. Obese subjects showed no differential response to the aromas of food and the inedible object when fasting. Within- and between-group differences in satiation were driven largely by changes in the response to the odor of the inedible stimulus. Responses to food aromas in the obese correlated with trait negative urgency, the tendency toward negative affect-provoked impulsivity. Conclusions: Ventral frontal signaling of reward value may be disordered in obesity, with negative urgency heightening responses to food aromas. The observed nature of responses to food and nonfood stimuli suggests that future research should independently quantify each to fully understand brain reward signaling in obesity. This trial was registered at clinicaltrials.gov as NCT02041039. PMID:24695888

    Abstract Background The postpartum period may be critical for the development of midlife obesity. Identifying factors associated with postpartum weight change could aid in targeting women for healthy lifestyle interventions. Methods Data from Active Mothers Postpartum (AMP), a study of overweight and obese postpartum women (n=450), were analyzed to determine the effect of baseline characteristics, breastfeeding, diet, physical activity, and contraception on weight change from 6 weeks to 12, 18, and 24 months postpartum. The repeated measures mixed model was used to test the association of these effects with weight change. Results Although mean weight loss was modest (0.49 kg by 24 months), the range of weight change was striking (+21.5 kg to −24.5 kg, standard deviation [SD] 7.4). Controlling only for baseline weight, weight loss was associated with breastfeeding, hormonal contraception, lower junk food and greater healthy food intake, and greater physical activity. Only junk food intake and physical activity were significant after controlling for all other predictors. Conclusions Eating less healthy foods and being less physically active put overweight and obese women at risk of gaining more weight after a pregnancy. PMID:22092110

    Objective. The aim of this study was to evaluate the impact of two exercise programs, whole body vibration and resistance training on bone mineral density (BMD) and anthropometry in obese postmenopausal women. Material and Methods. Eighty Egyptian obese postmenopausal women were enrolled in this study; their age ranged from 50 to 68 years. Their body mass index ranged (30–36 kg/m2). The exercise prescription consisted of whole body vibration (WBV) and resistance training. Bone mineral density (BMD) and anthropometrical parameters were measured at the beginning and at the end of the study. Changes from baseline to eight months in BMD and anthropometric parameters were investigated. Results. BMD at the greater trochanter, at ward's triangle, and at lumbar spine were significantly higher after physical training, using both WBV and resistive training. Moreover, both exercise programs were effective in BMI and waist to the hip ratio. Simple and multiple regression analyses showed significant associations between physical activity duration and BMD at all sites. The highest values of R2 were found for the models incorporating WBV plus BMI. Conclusion. The study suggests that both types of exercise modalities had a similar positive effect on BMD at all sites in obese postmenopausal women. Significant association was noted between physical activity and anthropometric variables and BMD measures at all sites. PMID:25136473

    Background: This study aimed to determine whether motivational interviewing (MI) could change dietary habit and body mass index (BMI) in obese/overweight women. Methods: A cluster-randomized controlled study was performed in four health centers in Qazvin, central Iran. In total, 327 obese/overweight women were selected by a multi-stage sampling method and randomly assigned into control and experimental groups. Food frequency (using questionnaire; FFQ), BMI, and metabolic markers including blood pressure, total serum cholesterol and fasting blood glucose levels were measured in all participants. Data were collected twice (before and one year after the MI interventions). Data were analyzed using student t-test, and Stepwise Linear Regression. Results: There was a significant increase in daily consumption of dietary fiber, whole grain products, fruits and vegetables in the MI group (P<0.05). The consumption of meat product, total fat, saturated fat, carbohydrate and total energy intake were also significantly reduced after MI intervention (P<0.05). As a result, body weight and BMI were significantly reduced in the intervention group compared to the control group (P<0.05). Conclusion: MI is suggested to be an effective strategy to change life style and reduce BMI in overweight/obese women in the long term. This effect needs to be further investigated in different gender and age populations. PMID:25648690

    The study investigated the dietary habits and foods that are associated with obesity in women from a rural area in Mexico. Anthropometry and body fat were measured in 580 women. Participants answered a socioeconomic and a food-frequency questionnaire; a subsample (n = 80) also answered three 24-hour-recall questionnaires. Results showed that obese women consumed more soft drinks and fat than did overweight and normal-weight women. Women who consumed more energy during a mid-morning meal had higher BMI. A strategy to decrease the prevalence of obesity in rural areas could be to encourage limiting the consumption of soft drinks and eliminating or reducing caloric intake at a mid-morning meal.

    Background/Objectives Short-term studies have suggested beneficial effects of a Palaeolithic-type diet (PD) on body weight and metabolic balance. We now report long-term effects in obese postmenopausal women of a PD on anthropometric measurements and metabolic balance, in comparison with a diet according to the Nordic Nutrition Recommendations (NNR). Subjects/Methods Seventy obese postmenopausal women (mean age 60 years, body mass index 33 kg/m2) were assigned to an ad libitum PD or NNR diet in a 2-year randomized controlled trial. The primary outcome was change in fat mass as measured by dual energy X-ray absorptiometry. Results Both groups significantly decreased total fat mass at 6 months (−6.5 and −2.6 kg) and 24 months (−4.6 and −2.9 kg), with a more pronounced fat loss in the PD group at 6 months (P<0.001), but not at 24 months (P=0.095). Waist circumference and sagittal diameter also decreased in both groups, with a more pronounced decrease in the PD group at 6 months (−11.1 vs. −5.8 cm, P=0.001 and −3.7 vs. −2.0 cm, P<0.001, respectively). Triglyceride levels decreased significantly more at 6 and 24 months in the PD group versus the NNR group (P<0.001 and P=0.004). Nitrogen excretion did not differ between groups. Conclusions A PD has greater beneficial effects versus an NNR diet regarding fat mass, abdominal obesity and triglyceride levels in obese postmenopausal women; effects not fully sustained for anthropometric measurements at 24 months. Adherence to protein intake was poor in the PD group. The long-term consequences of these changes remain to be studied. PMID:24473459

    General obesity, typically measured using body mass index (BMI), has been associated with an increased risk of several cancers. However, few prospective studies have been conducted in Asian populations. Although central obesity, often measured using waist-hip ratio (WHR), is more predictive for type 2 diabetes and cardiovascular diseases (CVD) risk than BMI, knowledge of its association with cancer incidence is limited. In a cohort of 68,253 eligible Chinese women, we prospectively investigated the association of BMI, WHR and weight change during adulthood with risk of overall cancer and major site-specific cancers using multivariate Cox proportional hazard models. Compared to the BMI group of 18.5-22.9 kg/m(2) , obese (BMI ≥ 30 kg/m(2) ) women were at an increased risk of developing overall cancer (hazard ratio = 1.36, 95% confidence interval = 1.21-1.52), postmenopausal breast cancer (HR: 2.43, 95% CI: 1.73-3.40), endometrial cancer (HR: 5.34, 95% CI: 3.48-8.18), liver cancer (HR: 1.93, 95% CI: 1.14-3.27) and epithelial ovarian cancer (HR: 2.44, 95% CI: 1.37-4.35). Weight gain during adulthood (per 5 kg gain) was associated with increased risk of all cancers combined (HR: 1.05, 95% CI: 1.03-1.08), postmenopausal breast cancer (HR: 1.17, 95% CI: 1.10-1.24) and endometrial cancer (HR: 1.37, 95% CI: 1.27-1.48). On the other hand, WHR was not associated with cancer risk after adjustment for baseline BMI. These findings suggest that obesity may be associated with cancer risk through different mechanisms from those for type 2 diabetes and CVD and support measures of maintaining health body weight to reduce cancer risk in Chinese women.

    Maternal preconception diet is proposed to affect fertility. Prior research assessing the effect of altering the fatty acid profile on female fertility is conflicting. The aim of this study was to assess the effect of preconception maternal diet, specifically fatty acid profile, on pregnancies and live births following in vitro fertilisation (IVF). Forty-six overweight and obese women undergoing IVF were randomised to a diet and physical activity intervention (intervention) or standard care (control). Outcome measures included pregnancy, live birth and pre-study dietary intake from food frequency questionnaire. Twenty pregnancies (n = 12/18 vs. n = 8/20, p = 0.12) and 12 live births (n = 7/18 vs. n = 5/20, p = 0.48) occurred following the intervention with no differences between the treatment groups. On analysis adjusted for BMI and smoking status, women who became pregnant had higher levels of polyunsaturated fatty acid (PUFA) intake (p = 0.03), specifically omega-6 PUFA and linoleic acid (LA) (p = 0.045) with a trend for an elevated intake of omega-3 PUFA (p = 0.06). There were no dietary differences for women who did or did not have a live birth. Maternal preconception PUFA, and specifically omega-6 and LA intake, are associated with improved pregnancy rates in overweight and obese women undergoing IVF. This has implications for optimising fertility through preconception nutrition. PMID:26742065

    A shift from home-prepared to away-from-home and ready-to-eat foods has occurred in recent decades, which has implications for obesity and health. This study tested whether delay discounting, a facet of impulsivity reflecting sensitivity to immediate reward, is associated with the frequency of consumption and typical amount consumed of home-prepared, away-from-home, and ready-to-eat foods among overweight and obese women. Seventy-eight participants completed a binary choice task assessing discounting of delayed monetary rewards. Nutrient analysis of weighed food records characterized dietary intake over seven consecutive days. Foods were categorized as home-prepared, away-from-home, or ready-to-eat by a registered dietitian from information provided by participants. Delay discounting was not associated with the frequency of consuming home-prepared, away-from-home, and ready-to-eat foods as reflected in the percentages of recorded foods or total energy intake from each category. However, once consuming away-from-home and ready-to-eat foods (but not home-prepared foods), impulsive women consumed more energy than less impulsive women. Exploratory analyses indicated that more impulsive women chose away-from-home foods with a higher energy density (kcal/g). Impulsivity was associated with the quantity of away-from-home and ready-to-eat foods consumed, but not the frequency of their consumption. Home food preparation may be critical to weight control for impulsive individuals. PMID:22819735

    This secondary analysis describes sleep and health-related factors in healthy overweight and obese mid-life and older rural women enrolled in the" Women Weigh-In for Wellness" randomized clinical trial. The aim of the trial was to promote healthy behaviors and weight-loss. We analyzed demographic, anthropometric, and biomarker variables, self-reported measurements of sleep disturbance and pain interference, and objective 24-h sleep/wake patterns at baseline, 6 months, and the change over time. Although self-reported sleep disturbance reflected normal sleep, pain interference was slightly higher than normal. There were associations between higher self-reported sleep disturbance, pain interference and several other variables. Women who achieved 5 % or more weight loss exhibited positive associations between sleep, pain, and health-related factors. Weight loss and lower pain predicted lower self-reported sleep disturbance. Our results suggest that overweight and obese rural women who adopt healthy behaviors and achieve weight loss also may experience improved sleep and other health benefits.

    Postmenopausal women have increased wave reflection (augmentation pressure (AP) and index (AIx)) and reduced muscle function that predispose them to cardiac diseases and disability. Our aim was to examine the combined and independent effects of whole-body vibration training (WBVT) and l-citrulline supplementation on aortic hemodynamics and plasma nitric oxide metabolites (NOx) in postmenopausal women. Forty-one obese postmenopausal women were randomized to 3 groups: l-citrulline, WBVT+l-citrulline and WBVT+Placebo for 8 weeks. Brachial and aortic systolic blood pressure, diastolic blood pressure, AP, AIx, AIx adjusted to 75 beats/min (AIx@75), and NOx were measured before and after 8 weeks. All groups similarly decreased (P < 0.05) brachial and aortic pressures as well as AP, and similarly increased (P < 0.05) NOx levels. AIx and AIx@75 decreased (P < 0.01) in the WBVT+l-citrulline and WBVT+Placebo groups, but not in the l-citrulline group. The improvement in AIx@75 (-10.5% ± 8.8%, P < 0.05) in the WBVT+l-citrulline group was significant compared with the l-citrulline group. l-Citrulline supplementation and WBVT alone and combined decreased blood pressures. The combined intervention reduced AIx@75. This study supports the effectiveness of WBVT+l-citrulline as a potential intervention for prevention of hypertension-related cardiac diseases in obese postmenopausal women. PMID:26863234

    Developing countries including Indonesia imperatively require an understanding of factors leading to the emerging problem of obesity, especially within low socio-economic groups, whose dietary pattern may contribute to obesity. In this cross-sectional study, we compared the dietary patterns and food consumption of 103 obese and 104 normal-weight women of reproductive age (19-49 years) in urban slum areas in Central Jakarta. A single 24-h food recall was used to assess energy and macronutrient intakes (carbohydrate, protein and fat) and calculate energy density. A principal component analysis was used to define the dietary patterns from the FFQ. Obese women had significantly higher intakes of energy (8436·6 (sd 2358·1) v. 7504·4 (sd 1887·8) kJ (2016·4 (sd 563·6) v. 1793·6 (sd 451·2) kcal)), carbohydrate (263·9 (sd 77·0) v. 237·6 (sd 63·0) g) and fat (83·11 (sd 31·3) v. 70·2 (sd 26·1) g) compared with normal-weight women; however, their protein intake (59·4 (sd 19·1) v. 55·9 (sd 18·5) g) and energy density (8·911 (sd 2·30) v. 8·58 (sd 1·88) kJ/g (2·13 (sd 0·55) v. 2·05 (sd 0·45) kcal/g)) did not differ significantly. Two dietary patterns were revealed and subjectively named 'more healthy' and 'less healthy'. The 'less healthy' pattern was characterised by the consumption of fried foods (snacks, soyabean and roots and tubers) and meat and poultry products, whereas the more healthy pattern was characterised by the consumption of seafood, vegetables, eggs, milk and milk products and non-fried snacks. Subjects with a high score for the more healthy pattern had a lower obesity risk compared with those with a low score. Thus, obesity is associated with high energy intake and unhealthy dietary patterns characterised by consumption of oils and fats through fried foods and snacks. PMID:26931206

    The present study investigated the impact of a Lactobacillus rhamnosus CGMCC1.3724 (LPR) supplementation on weight loss and maintenance in obese men and women over 24 weeks. In a double-blind, placebo-controlled, randomised trial, each subject consumed two capsules per d of either a placebo or a LPR formulation (1.6 × 10(8) colony-forming units of LPR/capsule with oligofructose and inulin). Each group was submitted to moderate energy restriction for the first 12 weeks followed by 12 weeks of weight maintenance. Body weight and composition were measured at baseline, at week 12 and at week 24. The intention-to-treat analysis showed that after the first 12 weeks and after 24 weeks, mean weight loss was not significantly different between the LPR and placebo groups when all the subjects were considered. However, a significant treatment × sex interaction was observed. The mean weight loss in women in the LPR group was significantly higher than that in women in the placebo group (P = 0.02) after the first 12 weeks, whereas it was similar in men in the two groups (P= 0.53). Women in the LPR group continued to lose body weight and fat mass during the weight-maintenance period, whereas opposite changes were observed in the placebo group. Changes in body weight and fat mass during the weight-maintenance period were similar in men in both the groups. LPR-induced weight loss in women was associated not only with significant reductions in fat mass and circulating leptin concentrations but also with the relative abundance of bacteria of the Lachnospiraceae family in faeces. The present study shows that the Lactobacillus rhamnosus CGMCC1.3724 formulation helps obese women to achieve sustainable weight loss. PMID:24299712

    This study examined racial differences in eating-disorder psychopathology, eating/weight-related histories, and biopsychosocial correlates in women (n = 53 Caucasian and n = 56 African American) with comorbid binge eating disorder (BED) and obesity seeking treatment in primary care settings. Caucasians reported significantly earlier onset of binge eating, dieting, and overweight, and greater number of times dieting than African American. The rate of metabolic syndrome did not differ by race. Caucasians had significantly elevated triglycerides whereas African Americans showed poorer glycaemic control (higher glycated haemoglobin A1c [HbA1c]), and significantly higher diastolic blood pressure. There were no significant racial differences in features of eating disorders, depressive symptoms, or mental and physical health functioning. The clinical presentation of eating-disorder psychopathology and associated psychosocial functioning differed little by race among obese women with BED seeking treatment in primary care settings. Clinicians should assess for and institute appropriate interventions for comorbid BED and obesity in both African American and Caucasian patients. PMID:26640009

    Background: Clinic care for morbid obesity is not very effective. Bariatric surgery is being considered the best way of intervention for this kind of obesity. Aim : Evaluate the clinical and nutritional evolution during the first year of obese women submitted to Roux-en-Y gastric bypass. Method : Retrospective series non-concurrent with 61 women. The variables were weight, BMI, weight loss percentage, loss of excessive weight percentage, waist circumference, hip circumference, lipid profile, daily use of supplements, practice of physical exercise, occurrence of sickness, nausea, constipation, diarrhea, asthenia, alopecia, dry skin, cramps and brittle nails. Results : They presented significant weight and IMC reduction as well as improvement in their lipid profile, in all consultations. After one year they presented 36,6% loss of the initial weight and 75% loss of excessive weight. The waist circumference also presented a considerable reduction on all the moments, decreasing from 122,1±13,4 cm to 94,1±10,6 cm. Regarding the intercurrences, the most frequent were alopecia, asthenia, dry skin and cramps. Conclusion : The Roux-en-Y gastric bypass was effective in promoting and maintenance weight loss during the period of the first postoperative year. PMID:26537276

    Obesity is a major health problem in the USA, especially in minority populations over the age of 60 years, and the aging process can cause adverse effects on physical function. Previous research has shown that Tai Chi, resistance training (RT), and diet result in overall health improvements. However, the combination of these specific interventions has yet to be translated to obese older women in an urban setting. The purpose of this study was to examine a combined intervention on the primary outcomes of physical function and body composition. Using a nonrandomized design, 26 obese women (65.2 ± 8.1 years) completed a 12-week intervention; participants were assigned to an intervention (EXD) group or a control (CON) group. The EXD group (n = 17) participated in Tai Chi, RT, and a dietary session. The CON group (n = 9) was asked to continue their normal lifestyle. Timed up and go (TUG) time was reduced by 0.64 ± 2.1 seconds (P = 0.04) in the EXD group while the CON group saw a borderline significant increase of 0.71 sec (P = 0.051). The combined intervention helped improve performance on TUG time, but there were no significant increases in other body composition or function measures. PMID:25614836

    The purpose of this study was to compare the temporal foot rollover data between straight-ahead and side-cut walking and to establish a reference dataset for obese and nonobese postmenopausal women. Pressure data were collected using the two-step protocol. The initial, final, and duration of contact of 10 foot areas were measured, as 5 instants and 4 phases. Significant temporal foot rollover differences were found during walking with and without directional changes; however, most of these differences were common for obese and nonobese subjects.The trailing limb during the side-cut task anticipated the initial and final contact of the lateral forefoot and increased midfoot and toes duration, suggesting a greater role of these areas in the initial break and in foot stability. The leading limb throughout the side-cut task exhibited longer duration of the heel, midfoot, and stance phase probably due to an increase in the stride length of the trailing limb and leaning of the trunk toward the inner side of the turn. Additionally, obese women revealed a later final contact and longer contact duration of some metatarsal areas suggesting that the greater inertia of these subjects demands more time to stabilize and prepare the foot for the next step.

    Obese women with type 2 diabetes mellitus (T2DM) have more inflammation in their subcutaneous white adipose tissue (sWAT) than age-and-BMI similar obese women with normal glucose tolerance (NGT). We aimed to investigate whether WAT fatty acids and/or oxylipins are associated with the enhanced inflammatory state in WAT of the T2DM women. Fatty acid profiles were measured in both subcutaneous and visceral adipose tissue (vWAT) of 19 obese women with NGT and 16 age-and-BMI similar women with T2DM. Oxylipin levels were measured in sWAT of all women. Arachidonic acid (AA) and docosahexaenoic acid (DHA) percentages were higher in sWAT, but not vWAT of the T2DM women, and AA correlated positively to the gene expression of macrophage marker CD68. We found tendencies for higher oxylipin concentrations of the 5-LOX leukotrienes in sWAT of T2DM women. Gene expression of the 5-LOX leukotriene biosynthesis pathway was significantly higher in sWAT of T2DM women. In conclusion, AA and DHA content were higher in sWAT of T2DM women and AA correlated to the increased inflammatory state in sWAT. Increased AA content was accompanied by an upregulation of the 5-LOX pathway and seems to have led to an increase in the conversion of AA into proinflammatory leukotrienes in sWAT. PMID:26378572

    Ecologic models suggest that multiple levels of influencing factors are important for determining physical activity participation and include individual, social, and environmental factors. The purpose of this qualitative study was to use an ecologic framework to gain a deeper understanding of the underlying behavioral mechanisms that influence physical activity adoption among ethnic minority women. Eighteen African American and Hispanic women completed a 1-hour in-depth interview. Verbatim interview transcripts were analyzed for emergent themes using a constant comparison approach. Women were middle-aged (age M = 43.9 ± 7.3 years), obese (body mass index M = 35.0 ± 8.9 kg/m(2)), and of high socioeconomic status (88.9% completed some college or more, 41.2% reported income >$82,600/year). Participants discussed individual factors, including the need for confidence, motivation and time, and emphasized the importance of environmental factors, including their physical neighborhood environments and safety of and accessibility to physical activity resources. Women talked about caretaking for others and social support and how these influenced physical activity behavior. The findings from this study highlight the multilevel, interactive complexities that influence physical activity, emphasizing the need for a more sophisticated, ecologic approach for increasing physical activity adoption and maintenance among ethnic minority women. Community insight gleaned from this study may be used to better understand determinants of physical activity and develop multilevel solutions and programs guided by an ecologic framework to increase physical activity in ethnic minority women.

    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

    Summary Objective To estimate the extent to which varus malalignment, a source of abnormal intra-articular stresses in the medial tibiofemoral compartment and risk factor for progression of knee osteoarthritis (OA), may have diminished the structure-modifying benefit of doxycycline in knee OA. Methods Post hoc treatment group comparisons from a randomized, placebo-controlled trial of the effect of doxycycline (100 mg, twice daily) on medial joint space narrowing (JSN) in subgroups of varus and non-varus OA knees. Subjects (N=379 with x-ray follow-up) were obese 45–64 year old women with unilateral knee OA at baseline. JSN was measured manually in semiflexed anteroposterior radiographs acquired with standardized fluoroscopic positioning. The anatomic-axis angle was measured in each baseline radiograph and transformed to an estimate of the mechanical-axis angle (MAAest) using a validated regression equation. Knees with MAAest <178° were classified as varus. Results In our original comparison with placebo, doxycycline slowed the rate of medial JSN in OA knees by 38% at 16 months and by 33% at 30 months. Among non-varus OA knees, 16-mo JSN in the doxycycline group was 44% slower than in the placebo group (0.09 vs. 0.16 mm/yr, P=0.080), and 39% slower at month 30 (0.10 vs. 0.17 mm/yr, P=0.026). JSN in varus knees (0.20–0.27 mm/yr) was more rapid than in non-varus knees (P=0.083) and unaffected by doxycycline. Conclusion Varus malalignment negated the slowing of structural progression of medial compartment OA by doxycycline. To our knowledge, this is the first report documenting that static varus angulation can negate a pharmacologic structure-modifying effect. PMID:20493957

    Context Black South African women are less insulin sensitive than their white counterparts, despite less central and greater peripheral fat deposition. We hypothesized that this paradox may be explained, in part, by differences in the adipogenic capacity of subcutaneous adipose tissue (SAT). Objective To measure adipogenic and lipogenic gene expression in abdominal and gluteal SAT depots, and determine their relationships with insulin sensitivity (SI) in South African women. Design Cross-sectional. Participants 14 normal-weight (BMI <25 kg/m2) black, 13 normal-weight white, 14 obese (BMI >30 kg/m2) black and 13 obese white premenopausal South African women. Main outcomes SI (frequently sampled intravenous glucose tolerance test) in relation to expression of adipogenic and lipogenic genes in abdominal and gluteal SAT depots. Results With increasing BMI, black women had less visceral fat (P=0.03) and more abdominal (P=0.017) and gynoid (P=0.041) SAT but had lower SI (P<0.01) than white women. The expression of adipogenic and lipogenic genes was proportionately lower with obesity in black, but not white women in the gluteal and deep SAT depots (P<0.05 for ethnicity x BMI effect). In black women only, the expression of these genes correlated positively with SI (all P<0.05), independently of age and fat mass. Conclusions Obese black women have reduced SAT expression of adipogenic and lipogenic genes compared to white women, which associates with reduced SI. These findings suggest that obesity in black women impairs SAT adipogenesis and storage, potentially leading to insulin resistance and increased risk of type 2 diabetes. PMID:21956425

    Nesfatin-1 is cleaved from nucleobindin2 (NUCB2) and implicated in the regulation of hunger and satiety as anorexigenic peptide hormone. Circulating NUCB2/nesfatin-1 is elevated in obesity and decreased in anorexia nervosa. In addition, a role in the regulation of stress, anxiety and depression has been demonstrated. First evidence suggested that NUCB2/nesfatin-1 might be regulated in a sex-specific manner. Thus, we investigated NUCB2/nesfatin-1 plasma levels in association with perceived stress, anxiety and depressiveness in obese men and women. We enrolled 140 inpatients (87 female, 53 male; body mass index, BMI, 30.3-81.7 kg/m(2)) hospitalized due to obesity with mental and somatic comorbidities. Perceived stress (PSQ-20), anxiety (GAD-7), and depressiveness (PHQ-9) were measured psychometrically, and at the same time NUCB2/nesfatin-1 plasma levels by ELISA. Males and females did not differ in terms of age and BMI. NUCB2/nesfatin-1 did not show a correlation with age or BMI. Mean NUCB2/nesfatin-1 levels (+25%, p<0.001) as well as mean scores for perceived stress (+26%, p < 0.01), anxiety (+54%, p < 0.001) and depressiveness (+32%, p = 0.02) were higher in females compared to males. Scores for perceived stress (r = 0.39; p < 0.001) and depressiveness (r = 0.35; p < 0.01) showed a positive correlation with NUCB2/nesfatin-1 in women, while in men no correlation was observed (p>0.19). The strongest association was observed between NUCB2/nesfatin-1 and anxiety with a positive correlation in women (r = 0.54; p < 0.001), while in men even an inverse correlation was found (r = -0.32; p = 0.03). This result was reflected in higher NUCB2/nesfatin-1 levels in women with high versus low anxiety (+51%, p<0.001) and an opposite alteration in men (-17%, p = 0.04) after a median split into two groups with high and low anxiety. In conclusion, circulating NUCB2/nesfatin-1 showed a positive correlation with anxiety, perceived stress, and depressiveness in obese women. In men, no

    Introduction Obesity is rapidly growing problem worldwide. It predisposes to a variety of serious ailments including heart disease, diabetes mellitus, degenerative joint disease, atherosclerosis, etc. This is probably related to proinflammatory state associated with obesity due to release of several inflammatory mediators by the adipose tissue. The mediators are also probably responsible for metabolic syndrome associated with obesity. Besides, they may also induce significant changes in haematological parameters associated with inflammation. Aim Present study was undertaken to ascertain the relationship between obesity and leucocyte counts (particularly TLC and ANC) and find out if the changes induced in them are significant enough to be used as predictors of metabolic syndrome. Materials and Methods This case-control study was carried out on 243 female subjects allocated to four groups based on WHO and IDF criteria: Control, Overweight, Obese and Obese with Metabolic Syndrome. From all the subjects, data pertaining to obesity related anthropometric measurements, lipid profile, fasting plasma glucose levels and complete blood counts were collected. These were analysed statistically. Results There was a strong positive correlation between obesity related anthropometric measurements (BMI, BF, WC) and leucocyte counts – TLC and ANC – which were statistically highly significant; TNC and ANC also showed strong positive correlation with FPG. Mean values for TLC and ANC showed statistically significant difference between each and every group. The difference in the mean values of these parameters between obese and metabolic syndrome was highly significant. Both elevated FPG and BMI were independently associated with relative leucocytosis; when both of them were elevated simultaneously, the effect appeared to be potentiating. Conclusion Increase in obesity associated anthropometric measurements (BMI, WC, BF) is associated with relative leucocytosis within the

Uncovering the mechanisms involved in GH secretion following oral glucose (OG) administration in normal and obese patients is a pending issue. Objective The aim of this study was to investigate GH after OG in relation with adiposity, insulin secretion and action, and ghrelin secretion in obese and healthy women, to further elucidate the mechanism of GH secretion after OG and the altered GH secretion in obesity. Participants and Methods We included 64 healthy and obese women. After an overnight fast, 75 g of OG were administered; GH, glucose, insulin and ghrelin were obtained during 300 minutes. Insulin secretion and action indices and the area under the curve (AUC) were calculated for GH, glucose, insulin and ghrelin. Univariate and multivariate linear regression analyses were employed. Results The AUC of GH (μg/L•min) was lower in obese (249.8±41.8) than in healthy women (490.4±74.6), P=0.001. The AUC of total ghrelin (pg/mL•min) was lower in obese (240995.5±11094.2) than in healthy women (340797.5±37757.5), P=0.042. There were significant correlations between GH secretion and the different adiposity, insulin secretion and action, and ghrelin secretion indices. After multivariate analysis only ghrelin AUC remained a significant predictor for fasting and peak GH. PMID:25782001

  18. Effect of obesity and low back pain on spinal mobility: a cross sectional study in women

    PubMed Central

    2010-01-01

    Background obesity is nowadays a pandemic condition. Obese subjects are commonly characterized by musculoskeletal disorders and particularly by non-specific chronic low back pain (cLBP). However, the relationship between obesity and cLBP remains to date unsupported by an objective measurement of the mechanical behaviour of the spine and its morphology in obese subjects. Such analysis may provide a deeper understanding of the relationships between function and the onset of clinical symptoms. Purpose to objectively assess the posture and function of the spine during standing, flexion and lateral bending in obese subjects with and without cLBP and to investigate the role of obesity in cLBP. Study design Cross-sectional study Patient sample thirteen obese subjects, thirteen obese subjects with cLBP, and eleven healthy subjects were enrolled in this study. Outcome measures we evaluated the outcome in terms of angles at the initial standing position (START) and at maximum forward flexion (MAX). The range of motion (ROM) between START and MAX was also computed. Methods we studied forward flexion and lateral bending of the spine using an optoelectronic system and passive retroreflective markers applied on the trunk. A biomechanical model was developed in order to analyse kinematics and define angles of clinical interest. Results obesity was characterized by a generally reduced ROM of the spine, due to a reduced mobility at both pelvic and thoracic level; a static postural adaptation with an increased anterior pelvic tilt. Obesity with cLBP is associated with an increased lumbar lordosis. In lateral bending, obesity with cLBP is associated with a reduced ROM of the lumbar and thoracic spine, whereas obesity on its own appears to affect only the thoracic curve. Conclusions obese individuals with cLBP showed higher degree of spinal impairment when compared to those without cLBP. The observed obesity-related thoracic stiffness may characterize this sub-group of patients, even

    It has been recognized that obese individuals are intrinsically in a state of chronic inflammation, as indicated by positive correlations between serum levels of C-reactive protein (CRP) and various anthropometric measures of obesity. To explore the hypothesis that a gene(s) may underlie this relationship, we conducted bivariate linkage analyses of BMI and CRP in white and African-American (AA) families of the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study (FHS). Variance components linkage analysis as implemented in SOLAR was performed in 1,825 whites (840 men and 985 women) and 548 AAs (199 men and 351 women). CRP exhibited significant genetic correlations with BMI in women (0.54 ± 0.10 for white and 0.53 ± 0.14 for AA) and the combined samples (0.37 ± 0.09 for white and 0.56 ± 0.13 for AA), but not in men. We detected a maximum bivariate lod score of 3.86 on chromosome 12q24.2–24.3 at 139 cM and a suggestive linkage signal (lod = 2.19) on chromosome 19p13.1 (44 cM) in white women. Both bivariate peaks were substantially higher than their respective univariate lods at the same locus for each trait. No significant lod scores were detected in AAs. Our results indicate that chromosome 12q may harbor quantitative trait loci (QTLs) jointly regulating BMI and CRP in white women. PMID:19238141

    Objective It is unclear why despite a comparable cardiometabolic risk profile, “metabolically benign” overweight/obese individuals show an elevated risk of cardiovascular disease compared to normal weight individuals. Design and Methods In cross-sectional analyses, we compared levels of ectopic fat (epicardial, pericardial, and hepatic fat) and adipokines (leptin, soluble leptin receptor, and high molecular weight [HMW] adiponectin) among metabolically benign (MBOO) and at-risk overweight/obese (AROO), and metabolically benign normal weight (MBNW) women, screened for the Kronos Early Estrogen Prevention Study. We defined “metabolically benign” with ≤ 1, and “at-risk” with ≥2 components of the metabolic syndrome. Results Compared to MBOO women, AROO women had significantly elevated odds of being in the top tertile of epicardial fat (OR:1.76, 95%CI:1.04–2.99), hepatic fat (OR:1.90, 95%CI:1.12–3.24) and leptin (OR:2.15, 95%CI:1.23–3.76), and the bottom tertile of HMW-adiponectin (OR:2.90, 95%CI:1.62–5.19). Compared to MBNW women, MBOO women had significantly higher odds of being in the top tertile of epicardial fat (OR:5.17, 95%CI:3.22–8.29), pericardial fat (OR:9.27, 95%CI:5.52–15.56) and hepatic fat (OR:2.72, 95%CI:1.77–4.19) and the bottom tertile of HMW adiponectin levels (OR:2.51, 95%CI:1.60–3.94). Conclusions Levels of ectopic fat and the adverse adipokine profile increase on a continuum of BMI, suggesting that the metabolically benign phenotype may be a transient state. PMID:23670850

    The aim of this study was to assess energy intake, resting metabolic rate (RMR), appetite sensations, eating behaviours and sleep duration and quality in obese women resistant to body weight loss when subjected to a diet-based weight-reducing programme. A pooled cohort of obese women (n = 75; aged 39 ± 8 years; body mass index: 33 ± 4 kg m(-2)) participated in a 12-16-week diet-based weight loss programme targeting a daily energy deficit of 500-700 kcal d(-1). Women were classified in tertiles a posteriori based on the response of their body weight to dietary supervision (high, moderate and low responders). Post-intervention, mean weight loss was 3.3 ± 2.8 kg and explained by the 2.9 ± 2.6 kg reduction in fat mass. Mean weight loss was 6.2 ± 1.6, 3.4 ± 0.6 and 0.2 ± 1.4 kg in participants classified in the high, middle and low tertiles, respectively. Women in the low tertile reduced their daily energy intake and susceptibility to hunger during the programme to a lesser extent than those in the high tertile and had higher fasting hunger in response to the dietary intervention. Women in the high tertile maintained their RMR, which was in contrast to the significant decrease predicted by their weight loss. They also reported a significant improvement in sleep quality and an increase in sleep duration compared with other tertiles. The differences in the response of body weight to dietary supervision may be explained, in part, by variations in energy intake, eating behaviours, appetite sensations and sleep duration and quality.

    BACKGROUND/OBJECTIVES This is the first study to identify common genetic factors associated with the basal metabolic rate (BMR) and body mass index (BMI) in obese Korean women including overweight. This will be a basic study for future research of obese gene-BMR interaction. SUBJECTS/METHODS The experimental design was 2 by 2 with variables of BMR and BMI. A genome-wide association study (GWAS) of single nucleotide polymorphisms (SNPs) was conducted in the overweight and obesity (BMI > 23 kg/m2) compared to the normality, and in women with low BMR (< 1426.3 kcal/day) compared to high BMR. A total of 140 SNPs reached formal genome-wide statistical significance in this study (P < 1 × 10-4). Surveys to estimate energy intake using 24-h recall method for three days and questionnaires for family history, a medical examination, and physical activities were conducted. RESULTS We found that two NRG3 gene SNPs in the 10q23.1 chromosomal region were highly associated with BMR (rs10786764; P = 8.0 × 10-7, rs1040675; 2.3 × 10-6) and BMI (rs10786764; P = 2.5 × 10-5, rs10786764; 6.57 × 10-5). The other genes related to BMI (HSD52, TMA16, MARCH1, NRG1, NRXN3, and STK4) yielded P <10 × 10-4. Five new loci associated with BMR and BMI, including NRG3, OR8U8, BCL2L2-PABPN1, PABPN1, and SLC22A17 were identified in obese Korean women (P < 1 × 10-4). In the questionnaire investigation, significant differences were found in the number of starvation periods per week, family history of stomach cancer, coffee intake, and trial of weight control in each group. CONCLUSION We discovered several common BMR- and BMI-related genes using GWAS. Although most of these newly established loci were not previously associated with obesity, they may provide new insights into body weight regulation. Our findings of five common genes associated with BMR and BMI in Koreans will serve as a reference for replication and validation of future studies on the metabolic rate. PMID:26865924

    2012-01-01

    Background Overweight and obesity pose a big challenge to pregnancy as they are associated with adverse maternal and perinatal outcome. Evidence of lifestyle intervention resulting in improved pregnancy outcome is conflicting. Hence the objective of this study is to determine the efficacy of antenatal dietary, activity, behaviour or lifestyle interventions in overweight and obese pregnant women to improve maternal and perinatal outcomes. Methods A systematic review and meta-analyses of randomised and non-randomised clinical trials following prior registration (CRD420111122 http://www.crd.york.ac.uk/PROSPERO) and PRISMA guidelines was employed. A search of the Cochrane Library, EMBASE, MEDLINE, CINAHL, Maternity and Infant care and eight other databases for studies published prior to January 2012 was undertaken. Electronic literature searches, study selection, methodology and quality appraisal were performed independently by two authors. Methodological quality of the studies was assessed according to Cochrane risk of bias tool. All appropriate randomised and non-randomised clinical trials were included while exclusions consisted of interventions in pregnant women who were not overweight or obese, had pre-existing diabetes or polycystic ovarian syndrome, and systematic reviews. Maternal outcome measures, including maternal gestational weight gain, gestational diabetes and Caesarean section, were documented. Fetal outcomes, including large for gestational age and macrosomia (birth weight > 4 kg), were also documented. Results Thirteen randomised and six non-randomised clinical trials were identified and included in the meta-analysis. The evidence suggests antenatal dietary and lifestyle intervention in obese pregnant women reduces maternal pregnancy weight gain (10 randomised clinical trials; n = 1228; -2.21 kg (95% confidence interval -2.86 kg to -1.59 kg)) and a trend towards a reduction in the prevalence of gestational diabetes (six randomised clinical trials; n

    Objectives To describe the relationship between minimum wage and overweight and obesity across countries at different levels of development. Methods A cross-sectional analysis of 27 countries with data on the legislated minimum wage level linked to socio-demographic and anthropometry data of non-pregnant 190,892 adult women (24–49 y) from the Demographic and Health Survey. We used multilevel logistic regression models to condition on country- and individual-level potential confounders, and post-estimation of average marginal effects to calculate the adjusted prevalence difference. Results We found the association between minimum wage and overweight/obesity was independent of individual-level SES and confounders, and showed a reversed pattern by country development stage. The adjusted overweight/obesity prevalence difference in low-income countries was an average increase of about 0.1 percentage points (PD 0.075 [0.065, 0.084]), and an average decrease of 0.01 percentage points in middle-income countries (PD -0.014 [-0.019, -0.009]). The adjusted obesity prevalence difference in low-income countries was an average increase of 0.03 percentage points (PD 0.032 [0.021, 0.042]) and an average decrease of 0.03 percentage points in middle-income countries (PD -0.032 [-0.036, -0.027]). Conclusion This is among the first studies to examine the potential impact of improved wages on an important precursor of non-communicable diseases globally. Among countries with a modest level of economic development, higher minimum wage was associated with lower levels of obesity. PMID:26963247

    This study aimed to examine the effects of a training program based on repetition of short-time walk sequences on cardiorespiratory response, physical performance and metabolic parameters in black Cameroonian obese women. One hundred thirty-nine obese women (body mass in-dex [BMI]>30 kg/m2) were divided into three groups: premenopausal (Pre-M; 39.7±7.9 yr; n=48), postmenopausal (Post-M; 55.0±2.5 yr; n=61) and control group (CONT; 48.7±9.4 yr; n=30). Only Pre-M and Post-M completed 24-week repeated short-time walking program. An-thropometric, cardiorespiratory, metabolic parameters, and the 6-min walk distance (6MWD) were measured at baseline (S1), 12 weeks follow-up (S2), and 2 days after the last session (S3). Significant changes were observed in weight, BMI, fatty mass and 6MWD in Pre-M and Post-M after 24 weeks. The waist and hip circumferences, percentages of water, muscle mass and bone mass changed in Post-M. Total cholesterol, triglycerides, low density lipoprotein and forced expiratory volumes in 1 and 6 sec showed significant improvements in Pre-M and Post-M. High density lipoprotein increased only in Post-M (0.5±0.2 g/L vs 0.7±0.1 g/L, P=0.041). In conclusion, this training modality could constitute an option for obese women rehabilitation.

    It was suggested that glucose metabolism and body fat content depend on serum levels of 25-hydroxyvitamin D [25(OH)D]. We studied 320 healthy women at late reproductive age of 40 to 52 years old (mean age 46.1±4.5) from St. Petersburg (North-West region of Russia). 25(OH)D levels were from 19.4 to 134.0 nMol/L (mean 52.9±22.7). Vitamin D deficiency (lower than 50 nMol/L) and insufficiency (50-75 nMol/L) was revealed in 59.1% and 27.8% of women, respectively. The study showed that low 25(OH)D levels were associated with obesity (r=-0.35, p<0.01), increased plasma glucose levels after OGTT (r=-0.31, p<0.01) and decreased insulin sensitivity index (r=-0.28, p<0.01). We found that 25(OH)D levels below 50 nMol/L were associated with obesity risk (OR 2.25[1.05-3.95], CI 95%) but not with risk of impaired glucose metabolism (1.07[0.54-2.12],CI95%). Our results showed that vitamin D insufficiency is highly prevalent in the population of healthy women. Low 25(OH)D levels correlated with high body fat, glucose levels and decreased insulin sensitivity. We conclude that vitamin D deficiency is a potential risk factor for obesity and development of insulin resistance leading to diabetes type 2. PMID:23924693

    The purpose of this study was to examine the relation between insulin sensitivity and cardiorespiratory fitness in overweight and obese postmenopausal women. The study population consisted of 127 overweight and obese postmenopausal women (age, 57.7 +/- 4.8 years; body mass index, 32.7 +/- 4.7 kg/m(2)). Subjects were classified by dividing the entire cohort into tertiles (T) based on insulin sensitivity expressed per kilograms of lean body mass (LBM) (T1, <10.9; T2, 10.9-12.9, T3, >12.9 mg/min per kilogram of LBM, respectively). Outcome measures were body composition (dual-energy x-ray absorptiometry), visceral adipose tissue (computed tomography), insulin sensitivity (hyperinsulinemic-euglycemic clamp), cardiorespiratory fitness (indirect calorimetry), lower-body muscle strength (1 maximal repetition), physical activity energy expenditure (doubly labeled water), fasting lipids, and inflammatory profile. We found a significant positive relationship between insulin sensitivity and cardiorespiratory fitness (r = 0.25, P = .005). Moreover, cardiorespiratory fitness was higher in the T3 group compared to the T1 group (36.2 +/- 6.1 vs 33.1 +/- 5.0 mL/kg LBM per minute, respectively; P = .028). However, the difference was no longer significant after controlling for visceral adipose tissue or muscle strength. Finally, cardiorespiratory fitness was an independent predictor of insulin sensitivity. High levels of cardiorespiratory fitness are associated with higher levels of insulin sensitivity in overweight and obese postmenopausal women. Moreover, visceral adipose tissue accumulation or muscle strength may be potential mediators of this relationship. PMID:18702957

    BACKGROUND: The fundamental cause of obesity and overweight is an energy imbalance between calories consumed and calories expended. AIM: To figure out food habits and different lifestyle pattern among a sample of Egyptian females working at the National Research Centre. METHODS: A cross-sectional, descriptive study, including 138 overweight and obese Egyptian females (BMI ≥ 25 Kg/m2); working at the National Research Centre; was done. A specific questionnaire was used to gather information regarding lifestyle including dietary habits, physical activity and sedentary behaviour. RESULTS: The prevalence of overweight among the studied subjects was 27%, while that of obesity was 38%. Missing and or infrequent intake of breakfast at home, frequent consumption of snacks, low serving per day of fruits and vegetables with frequent consumption of sweets, fried food, eating while watching TV and sedentary behaviour were all predictors of obesity and overweight among the current sample. CONCLUSION: The present study identified several lifestyle factors and improper dietary habits associated with overweight and obesity among Egyptian females. There is a great need to change these habits to avoid the increasing risk of obesity. A national plan of action to overcome obesity is urgently needed to reduce its economic and health burden.

    Childhood obesity is associated with many adverse health effects during childhood and is linked to an increased risk for obesity in adulthood. The objective of this study was to determine the characteristics of early childhood overweight and obesity and assess the impact of breastfeeding. Data from Hawai'i's Special Supplemental Nutrition Program for Women, Infants and Children (WIC) were analyzed for children 2 years of age born between 2005 and 2009 and their mothers. Childhood overweight and obesity was examined using a log-binomial regression model to estimate prevalence ratios. In the sample population, 12.5 % of children were overweight and 8.5 % of children were obese. Significant differences in childhood overweight and obesity were seen between breastfeeding duration and other socio-demographic groups. Children who were breastfed for 6 months or more had a lower risk of childhood obesity at age two compared to those who were never breastfed (APR 0.79, 95 % CI 0.69-0.91) with adjustment for child race/ethnicity, maternal age, trimester of prenatal care entry, maternal smoking status, and child birth weight. The prevalence of early childhood overweight and obesity is associated with shorter durations of breastfeeding. Early and continued breastfeeding support and education for mothers in the WIC program that improves duration of breastfeeding may help reduce the risk of early childhood obesity. PMID:24170508

    Obesity is a strong risk factor for nephrolithiasis, but the role of physical activity and caloric intake remains poorly understood. We evaluated this relationship in 84,225 women with no history of stones as part of the Women's Health Initiative Observational Study, a longitudinal, prospective cohort of postmenopausal women enrolled from 1993 to 1998 with 8 years' median follow-up. The independent association of physical activity (metabolic equivalents [METs]/wk), calibrated dietary energy intake, and body mass index (BMI) with incident kidney stone development was evaluated after adjustment for nephrolithiasis risk factors. Activity intensity was evaluated in stratified analyses. Compared with the risk in inactive women, the risk of incident stones decreased by 16% in women with the lowest physical activity level (adjusted hazard ratio [aHR], 0.84; 95% confidence interval [95% CI], 0.74 to 0.97). As activity increased, the risk of incident stones continued to decline until plateauing at a decrease of approximately 31% for activity levels ≥10 METs/wk (aHR, 0.69; 95% CI, 0.60 to 0.79). Intensity of activity was not associated with stone formation. As dietary energy intake increased, the risk of incident stones increased by up to 42% (aHR, 1.42; 95% CI, 1.02 to 1.98). However, intake <1800 kcal/d did not protect against stone formation. Higher BMI category was associated with increased risk of incident stones. In summary, physical activity may reduce the risk of incident kidney stones in postmenopausal women independent of caloric intake and BMI, primarily because of the amount of activity rather than exercise intensity. Higher caloric intake further increases the risk of incident stones. PMID:24335976

    Background and Aims New methods to measure visceral adipose tissue (VAT) by DEXA may help discern sex, race and phenotype differences in the role of VAT in cardiometabolic risk. This study was designed to: a) compare relationships between cardiometabolic risk factors and DEXA-VAT, anthropometric and body composition measures; b) determine thresholds for DEXA-VAT by race; and c) determine the most robust predictors of impaired glucose tolerance (IGT) and metabolic syndrome (MetSx) in obese women. Methods VAT area (cm2) was measured using Lunar iDXA scanner in 229 obese (BMI 30-49.9) women age 21–69 years of European American (EA = 123) and African American (AA = 106) descent. Linear regression modeling and areas under the curve (AUC) compared relationships with cardiometabolic risk. Bootstrapping with LASSO regression modeling determined thresholds and predictors of IGT and MetSx. Results DEXA-VAT explained more of the variance in triglycerides, blood pressure, glucose and HOMA-IR compared to anthropometric and body composition variables. DEXA-VAT had the highest AUC for IGT (0.767) and MetSx (0.749). Including race and interactionXrace terms in modeling did not significantly change results. Thresholds at which probability was ≥ 50% for IGT or MetSx were lower in AA women (IGT: 2120cm2 AA vs 2550cm2 EA; MetSx: 1320cm2 AA vs 1713cm2 EA). The odds for IGT or MetSx was 3-fold greater with each standard deviation increase in DEXA-VAT. Conclusion DEXA-VAT provides robust clinical information regarding cardiometabolic risk in AA and EA women and has great potential in risk reduction efforts. PMID:25335442

    To compare the utilization pattern of breast reconstruction between obese and non-obese patients and assess the association between obesity and postoperative complications as well as healthcare costs. Using MarketScan databases, we identified 2558 breast cancer patients who underwent mastectomy between 2009 and 2012. Temporal trends in breast reconstruction were assessed using the Cochran-Armitage test. Logistic regression models were performed to determine the association between obesity and the occurrence of postoperative complications. Healthcare costs were compared using a generalized linear model. Among 2558 patients treated with mastectomy, the breast reconstruction rate of non-obese patients (76.2 %) was significantly higher than patients in obese class I and class II&III (63.3 and 60.2 %, respectively; P < 0.001). Compared with non-obese patients, obese patients had significantly higher rates of infection (OR 1.53, for obese class I, and OR 1.60, for obese class II&III, both P < 0.01), wound (OR 1.51, P = 0.01 for obese class I, and OR 1.98, P < 0.001 for obese class II&III), and perfusion complications (OR 1.73, P = 0.01 for obese class I, and OR 2.21, P < 0.01 for obese class II&III). The mean postoperative complication cost for non-obese patients ($4684) was significantly lower than those for obese class I patients ($6250) and obese class II&III patients ($7868; P < 0.001). Our analysis demonstrated a significant gap in breast reconstruction between obese and non-obese patients, and our finding underscores the need for careful preoperative assessment of obese patients and call for additional research to minimize the risk of complications.

    Studies of obesity and related health conditions among the Bhutanese, one of the largest refugee groups resettled in the United States in the past five years, are limited. This study examined the factors associated with excess body weight (body mass index ≥ 23 kg/m2) and abdominal obesity (waist circumference > 80 cm) in a community-based sample of 18–65 year old Bhutanese refugee women in Northeast Ohio. A Nepali-language questionnaire was used to measure socio-demographic and dietary factors. Height, weight, and waist circumference were measured to define excess body weight and abdominal obesity. The mean (±standard deviation) age of the 108 participants was 36.5 (±12.2) years and length of time in the U.S. was 19.4 (±11.9) months. Overall, 64.8% and 69.4% of the women had excess body weight and abdominal obesity, respectively. Age was significantly associated with both excess body weight (odds ratio: 1.10; 95% confidence interval: 1.05–1.16) and abdominal obesity (1.09; 1.04–1.14). Consuming meat (4.01; 1.14–14.60) was significantly associated with excess body weight but not abdominal obesity. These findings suggest the need for lifestyle and dietary change education programs among this new and vulnerable group to reduce the prevalence of excess body weight and abdominal obesity and their health consequences.

    While undernutrition and infectious diseases are still persistent in developing countries, overweight, obesity, and associated comorbidities have become more prevalent. Uganda, a developing sub-Saharan African country, is currently experiencing the public health paradox of undernutrition and overnutrition. We utilized the 2011 Uganda Demographic and Health Survey (DHS) to examine risk factors and hot spots for underweight, overweight, and obesity among adult females (N = 2,420) and their children (N = 1,099) using ordinary least squares and multinomial logit regression and the ArcGIS Getis-Ord Gi* statistic. Overweight and obese women were significantly more likely to have overweight children, and overweight was correlated with being in the highest wealth class (OR = 2.94, 95% CI = 1.99–4.35), and residing in an urban (OR = 1.76, 95% CI = 1.34–2.29) but not a conflict prone (OR = 0.48, 95% CI = 0.29–0.78) area. Underweight clustered significantly in the Northern and Northeastern regions, while overweight females and children clustered in the Southeast. We demonstrate that the DHS can be used to assess geographic clustering and burden of disease, thereby allowing for targeted programs and policies. Further, we pinpoint specific regions and population groups in Uganda for targeted preventive measures and treatment to reduce the burden of overweight and chronic diseases in Uganda. PMID:24157515

  18. Do obese but metabolically normal women differ in intra-abdominal fat and physical activity levels from those with the expected metabolic abnormalities? A cross-sectional study

    PubMed Central

    2010-01-01

    Background Obesity remains a major public health problem, associated with a cluster of metabolic abnormalities. However, individuals exist who are very obese but have normal metabolic parameters. The aim of this study was to determine to what extent differences in metabolic health in very obese women are explained by differences in body fat distribution, insulin resistance and level of physical activity. Methods This was a cross-sectional pilot study of 39 obese women (age: 28-64 yrs, BMI: 31-67 kg/m2) recruited from community settings. Women were defined as 'metabolically normal' on the basis of blood glucose, lipids and blood pressure. Magnetic Resonance Imaging was used to determine body fat distribution. Detailed lifestyle and metabolic profiles of participants were obtained. Results Women with a healthy metabolic profile had lower intra-abdominal fat volume (geometric mean 4.78 l [95% CIs 3.99-5.73] vs 6.96 l [5.82-8.32]) and less insulin resistance (HOMA 3.41 [2.62-4.44] vs 6.67 [5.02-8.86]) than those with an abnormality. The groups did not differ in abdominal subcutaneous fat volume (19.6 l [16.9-22.7] vs 20.6 [17.6-23.9]). A higher proportion of those with a healthy compared to a less healthy metabolic profile met current physical activity guidelines (70% [95% CIs 55.8-84.2] vs 25% [11.6-38.4]). Intra-abdominal fat, insulin resistance and physical activity make independent contributions to metabolic status in very obese women, but explain only around a third of the variance. Conclusion A sub-group of women exists who are metabolically normal despite being very obese. Differences in fat distribution, insulin resistance, and physical activity level are associated with metabolic differences in these women, but account only partially for these differences. Future work should focus on strategies to identify those obese individuals most at risk of the negative metabolic consequences of obesity and on identifying other factors that contribute to metabolic status

    The present study was conducted in order to (i) characterize the adherence to the Mediterranean diet (MD) pattern and fatty acids (FAs) intakes and (ii) explore interactions between TNFA -308 G>A polymorphism and adherence to MD and FAs intakes, respectively, on overweight/obesity risk. From 2010 to 2013, 380 healthy women were enrolled, and MD score (MDS) and FAs intakes were evaluated by a Food Frequencies Questionnaire in relation to nutritional status. TNFA -308 G/A polymorphism was characterized using PCR-RFLP. A total of 32.6% of women were overweight or obese. Lower mean MDS values were more observed in the younger age group than in the older age group (3.60 versus 4.45). The risk of being overweight/obese was 3.5-fold increased due to poor adherence to MD and was about twofold increased in less educated women. Furthermore, younger age was associated with poor adherence to MD. No evidence for an independent effect of the polymorphism on overweight/obesity risk was found. There was no evidence of biological interaction from the gene-diet interaction analyses. Young women, less educated and with poor adherence to MD, are a target group for the nutritional interventions that aimed to control the obesity risk, thus improving the adherence to MD and particularly the intake of unsaturated FAs.

    Overeating is believed to result when the appetitive motivation to consume palatable food exceeds an individual's capacity for inhibitory control of eating. This hypothesis was supported in recent studies involving predominantly normal weight women, but has not been tested in obese populations. The current study tested the interaction between food reward sensitivity and inhibitory control in predicting palatable food intake among energy-replete overweight and obese women (N = 62). Sensitivity to palatable food reward was measured with the Power of Food Scale. Inhibitory control was assessed with a computerized choice task that captures the tendency to discount large delayed rewards relative to smaller immediate rewards. Participants completed an eating in the absence of hunger protocol in which homeostatic energy needs were eliminated with a bland preload of plain oatmeal, followed by a bogus laboratory taste test of palatable and bland snacks. The interaction between food reward sensitivity and inhibitory control was a significant predictor of palatable food intake in regression analyses controlling for BMI and the amount of preload consumed. Probing this interaction indicated that higher food reward sensitivity predicted greater palatable food intake at low levels of inhibitory control, but was not associated with intake at high levels of inhibitory control. As expected, no associations were found in a similar regression analysis predicting intake of bland foods. Findings support a neurobehavioral model of eating behavior in which sensitivity to palatable food reward drives overeating only when accompanied by insufficient inhibitory control. Strengthening inhibitory control could enhance weight management programs. PMID:21475139

    Using a crossover design, 22 normal-weight and 22 obese women completed two free-living sleep conditions: (a) Normal Sleep: night of ~8 hr time in bed; and (b) Reduced Sleep: night of < 5 hr time in bed). Outcome measures were energy intake, physical activity and sedentary time, and mood. Sleep time was 7.7 ± 0.3 and 4.8 ± 0.2 hrs during the Normal Sleep and Reduced Sleep conditions, respectively (F = 1791.94; p < 0.0001). Energy intake did not differ between groups or as a function of sleep condition (F = 2.46; p = 0.1244). Sedentary time was ~ 30 min higher after the Reduced Sleep condition (F = 4.98; p = 0.0318); other physical activity outcomes were not different by condition (p > 0.05). Total mood score, depression, anger, vigor, fatigue, and confusion were worse after Reduced Sleep (p < 0.05). Reducing sleep acutely and negatively influenced sedentary time and mood in normal-weight and obese women. PMID:26485109

    Few studies have assessed physical activity at multiple time points in the postpartum period or used both self-reported and objective measures of assessment. The purpose of this study was to describe physical activity and sedentary behavior at two time points in a cohort of overweight or obese postpartum women using both self-reported and objective measures. In total, 132 women completed physical activity assessments at a median of 24 weeks postpartum and again approximately 10 months later. At both time points, women wore an Actical accelerometer for one week and completed the Kaiser Physical Activity Survey at both time points. Adjusted Poisson regression models were used to determine whether physical activity changed over time for the cohort. Overall counts per minute and moderate to vigorous physical activity increased from baseline to 10-months later, although the absolute levels were modest (median 6.9 to 8.8 minutes/day). A median of 64–71% at baseline and 63–67% at follow-up of their monitored time was sedentary. More intensive interventions are needed to help postpartum women integrate physical activity and reduce sedentary behavior. PMID:23705761

    Background Research demonstrates a link between migraine and obesity. Obesity increases the risk of frequent migraines and is associated with migraine prevalence among reproductive-aged women. These findings are substantiated by several plausible mechanisms and emerging evidence of migraine improvements after surgical and non-surgical weight loss. However, no previous study has examined the effect of weight loss on migraine within a treatment-controlled framework. The WHAM trial is a RCT to test the efficacy of behavioral weight loss as a treatment for migraine. Study design Overweight/obese women (n=140; BMI=25.0–49.9 kg/m2) who meet international diagnostic criteria for migraine and record ≥3 migraines and 4–20 migraine days using a smartphone-based headache diary during a 4-week baseline period, will be randomly assigned to 4 months of either group-based behavioral weight loss (intervention) or migraine education (control). Intervention participants will be taught strategies to increase physical activity and consume fewer calories in order to lose weight. Control participants will receive general education on migraine symptoms/triggers and various treatment approaches. Both groups will use smartphones to record their headaches for 4 weeks at baseline, after the 16-week treatment period, and at the end of a 16-week follow-up period. Changes in weight and other potential physiological (inflammation), psychological (depression), and behavioral (diet and physical activity) mediators of the intervention effect will also be assessed. Conclusion The WHAM trial will evaluate the efficacy of a standardized behavioral weight loss intervention for reducing migraine frequency, and the extent to which weight loss and other potential mediators account for intervention effects.

    Recent studies have indicated that omega-3 (n3) polyunsaturated fatty acids (PUFAs) decrease adipose tissue inflammation in rodents and in morbidly obese humans. We investigated whether a diet rich in n3 PUFAs from both marine and plant sources reduces adipose tissue and systemic inflammation in overweight to moderately obese adults. We conducted a randomized, single-blind, parallel-design, placebo-controlled feeding trial. Healthy men and women with a body mass index between 28 and 33 kg/m2 consumed a diet rich in n3 PUFAs (3.5% of energy intake; n = 11) from plant and marine sources or a control diet (0.5% of energy intake from n3 PUFAs; n = 13). These diets were consumed for 14 wk (ad libitum for 12 wk). All foods were provided for the entire study period. Subcutaneous abdominal adipose tissue and fasting plasma were collected after the first 2 wk with the control diet and again at the end of the 14-wk dietary period. The primary outcome of this ex post analysis was the adipose tissue gene expression of 13 key mediators of inflammation. Adipose tissue gene expression of inflammatory mediators did not differ between the 2 groups, after adjustment for weight change. Furthermore, none of the 5 plasma markers of systemic inflammation differed significantly as an effect of diet treatment. We conclude that a relatively high dose of n3 PUFAs from plant and marine sources did not significantly lower adipose tissue or systemic inflammation in overweight to moderately obese healthy men and women over 14 wk.

    Background Ingestion of sweet food is driven by central reward circuits and restrained by endocrine and neurocrine satiety signals. The specific influence of sucrose intake on central affective and reward circuitry and alterations of these mechanisms in the obese are incompletely understood. For this, we hypothesized that (i) similar brain regions are engaged by the stimulation of sweet taste receptors by sucrose and by non-nutrient sweeteners and (ii) during visual food-related cues, obese subjects show greater brain responses to sucrose compared with lean controls. Methods In a double-blind, crossover design, 10 obese and 10 lean healthy females received a sucrose or a non-nutrient sweetened beverage prior to viewing food or neutral images. BOLD signal was measured using a 1.5 Tesla MRI scanner. Key Results Viewing food images after ingestion of either drink was associated with engagement of similar brain regions (amygdala, hippocampus, thalamus, anterior insula). Obese differed from lean subjects in behavioral and brain responses rating both beverages as less tasteful and satisfying, yet demonstrating greater brain responses. Obese subjects also showed engagement of an additional brain network (including anterior insula, anterior cingulate, hippocampus, and amygdala) only after sucrose ingestion. Conclusions & Inferences Obese subjects had a reduced behavioral hedonic response, yet a greater engagement of affective brain networks, particularly after sucrose ingestion, suggesting that in obese subjects, lingual and gut-derived signaling generate less central hedonic effects than food-related memories in response to visual cues, analogous to response patterns implicated in food addiction.

    Mindfulness-based stress reduction (MBSR) may be beneficial for overweight/obese women, including women with polycystic ovary syndrome (PCOS), as it has been shown to reduce psychological distress and improve quality of life in other patient populations. Preliminary studies suggest that MBSR may also have salutary effects on blood pressure and blood glucose. This paper describes the design and methods of an ongoing pilot randomized controlled trial evaluating the feasibility and effects of MBSR in PCOS and non-PCOS women who are overweight or obese. Eighty six (86) women with body mass index ≥25 kg/m2, including 31 women with PCOS, have been randomized to 8 weeks of MBSR or health education control, and followed for 16 weeks. The primary outcome is mindfulness assessed with the Toronto Mindfulness Scale. Secondary outcomes include measures of blood pressure, blood glucose, quality of life, anxiety and depression. Our overall hypothesis is that MBSR will increase mindfulness and ultimately lead to favorable changes in blood pressure, blood glucose, psychological distress and quality of life in PCOS and non-PCOS women. This would support the integration of MBSR with conventional medical treatments to reduce psychological distress, cardiovascular disease and diabetes in PCOS and non-PCOS women who are overweight or obese.

    Evidence from developing countries demonstrates a mixed relationship of overweight/obesity with socioeconomic status (SES) and place of residence. Theory of nutrition transition suggests that over the course of development, overweight first emerges among rich and urban people before spreading among rural and poor people. India is currently experiencing a rapid rise in the proportion of overweight and obese population especially among adult women. Under the backdrop of huge socio-economic heterogeneity across the states of India, the inter-state scenario of overweight and obesity differs considerably. Hence, this paper investigates the evolution over time of overweight and obesity among ever-married Indian women (15-49 years) from selected 'underweight states' (Bihar, Orissa and Madhya Pradesh, where underweight proportion is predominant) and 'overweight states' (Kerala, Delhi and Punjab, where overweight is the prime concern), in relation to a few selected socio-economic and demographic indicators. This study analysed National Family Health Surveys- NFHS-2 (1998-99) and NFHS-3 (2005-06) following Asian population specific BMI cut-offs for overweight and obesity. The results confirm that within India itself the relationship of overweight and obesity with place of residence and SES cannot be generalized. Results from 'overweight states' show that the overweight problem has started expanding from urban and well-off women to the poor and rural people, while the rural-urban and rich-poor difference has disappeared. On the other hand in 'underweight states' overweight and obesity have remained socially segregated and increasing strongly among urban and richer section of the population. The rate of rise of overweight and obesity has been higher in rural areas of 'OW states' and in urban areas of 'UW states'. Indian policymakers thus need to design state-specific approaches to arrest the rapid growth of overweight and its penetration especially towards under

    The skeletal muscle of obese individuals exhibits an impaired ability to increase the expression of genes linked with fatty acid oxidation (FAO) upon lipid exposure. The present study determined if this response could be attributed to differential DNA methylation signatures. RNA and DNA were isolated from primary human skeletal muscle cells (HSkMC) from lean and severely obese women following lipid incubation. mRNA expression and DNA methylation were quantified for genes that globally regulate FAO [PPARγ coactivator (PGC-1α), peroxisome proliferator-activated receptors (PPARs), nuclear respiratory factors (NRFs)]. With lipid oversupply, increases in NRF-1, NRF-2, PPARα, and PPARδ expression were dampened in skeletal muscle from severely obese compared with lean women. The expression of genes downstream of the PPARs and NRFs also exhibited a pattern of not increasing as robustly upon lipid exposure with obesity. Increases in CpG methylation near the transcription start site with lipid oversupply were positively related to PPARδ expression; increases in methylation with lipid were depressed in HSkMC from severely obese women. With severe obesity, there is an impaired ability to upregulate global transcriptional regulators of FAO in response to lipid exposure. Transient changes in DNA methylation patterns and differences in the methylation signature with severe obesity may play a role in the transcriptional regulation of PPARδ in response to lipid. The persistence of differential responses to lipid in HSkMC derived from lean and obese subjects supports the possibility of stable epigenetic programming of skeletal muscle cells by the respective environments.

    Maternal age at conception has long been demonstrated to have a significant correlation with pregnancy outcome and maternal health. Classically, very young (<20 years old) and old (= or >35 years) women have been classified as high-risk categories for child bearing. Recently, career, education, financial, and other goals have coerced women to delay childbearing all over the world. This trend is also becoming apparent in Pakistan, especially in the upper middle class, wealthy and educated women, as they become increasingly empowered. This review presents the association between maternal age and pregnancy outcome, particularly in the context of statistics of Pakistan, and its possible repercussions. On one hand, physicians need to develop effective counseling strategies for their patients in this regard, and on the other, more studies are required to ascertain the attitudes of Pakistani women, particularly those belonging to the upper and middle classes, regarding delayed childbearing, that can aid physicians in formulating effective counseling strategies.

    Background This study was designed to investigate the effect of metformin and flutamide alone or in combination with anthropometric indices and laboratory tests of obese/overweight PCOS women under hypocaloric diet. Methods This single blind clinical trial was performed on 120 PCOS women. At the beginning, hypocaloric diet was recommended for the patients. After one month while they were on the diet, the patients were randomly divided in 4 groups; metformin (500 mg, 3/day), flutamide (250 mg, 2/day), combined, metformin (500 mg, 3/day) with flutamide (250 mg, 2/day) and finally placebo group. The patients were treated for 6 months. Anthropometric indices and laboratory tests (fasting and glucose-stimulated insulin levels, lipid profile and androgens) were measured. A one-way ANOVA (Post Hoc) and paired t-test were performed to analyze data. A p ≤ 0.05 was considered statistically significant. Results After treatment, reduction in weight, BMI, hip circumference was significantly greater in the metformin group in comparison to other groups (p<0.05). In addition, the fasting insulin was significantly greater in metformin group and flutamide group in comparison to metformin+flutamide and placebo groups after treatment (p<0.05). Within groups, insulin level showed significant changes (before and after treatment) in metformin+flutamide group and LDL reduction was significant in flutamide group before and after treatment. Post hoc tukey and two-tailed with p≤0.05 were used to define statistical significance. Conclusion Using combination of metformin and flutamide improves anthropometric indices and laboratory tests in obese/overweight PCOS women under hypocaloric diet. PMID:25473629

    Introduction The research conducted among patients with depression shows that such patients commit a range of nutritional mistakes which may predispose them to the development of many diseases including obesity and its complications. Aim of the study Aim of the study was to assess the effectiveness of a balanced weight loss diet in a group of women with recurrent depressive disorders. Material and methods 60 women suffering from depression, aged 41-64 (mean 52 ±5.3) on a six-month weight loss diet took part in the study. The patients’ nutrition was assessed both in terms of quality and quantity, they were also subjected to anthropometric tests and their body composition was analysed. Results An average reduction in the women's body weight was 4.1 ±3.1 kg. The percentage content of the fatty tissue was reduced by 2.5 ±1.1% on average after modification of the nutrition (a statistically significant decrease in the frequency of wheat bread, cream, fat pork and eggs was observed). A considerable reduction in the mean energy value of the diet and a decrease in the total fat supply was also implemented. Conclusions It seems that the dietary procedure which is aimed at obtaining the most advantageous effects of the reduction in the body mass of obese patients suffering from depression should be based not only on proper selection of food products and reduction in the energy value of the diet, but it should also take into account actions aimed at introducing permanent lifestyle changes including increased motivation of the patients to undertake physical activity.

    Preproghrelin gene single-nucleotide polymorphisms are possible predisposing factors to obesity and other metabolic syndromes. To study the correlation between genotypes and obesity, we recruited 117 obese Japanese women (BMI, 25.0-41.1; average, 31.1). Minor homozygotes for five preproghrelin gene polymorphisms, namely, -1500C>G (rs3755777), -1062G>C (rs26311), -994C>T (rs26312) (promoter region), Leu72Met (rs696217) (exon 2), and +3056T>C (rs2075356) (intron 2), had high values of total and visceral fat areas, waist circumference, and BMI, indicating significant correlation of the polymorphisms with obesity and fat metabolism. Here, we studied the relationship between the genotypes and dietary tendency. Self-administered Diet History Questionnaire showed that total food intake, sugar, and dairy product intake were low in +3056C/C women. Their energy, protein, fat, and meat intake was also low. Energy balance calculation showed considerably reduced fat and protein consumption. Dietary habits were surveyed using Sakata's Questionnaire on Eating Behavior. Of the genotypes, -1062C/C women showed low scores for "motivation for eating" and "eating because of stress or something else." Thus, surprisingly, it was revealed that minor homozygotes for preproghrelin gene polymorphisms were light eaters, did not prefer fat or protein, and apparently had a poor appetite, although they were predisposed to obesity.

    The purpose of this study was to examine the psychosocial correlates of cardiorespiratory fitness (VO2peak) and muscle strength in overweight and obese sedentary post-menopausal women. The study population consisted of 137 non-diabetic, sedentary overweight and obese post-menopausal women (mean age 57.7 years, s = 4.8; body mass index 32.4 kg.m(-2), s = 4.6). At baseline we measured: (1) body composition using dual-energy X-ray absorptiometry; (2) visceral fat using computed tomography; (3) insulin sensitivity using the hyperinsulinaemic-euglycaemic clamp; (4) cardiorespiratory fitness; (5) muscle strength using the leg press exercise; and (6) psychosocial profile (quality of life, perceived stress, self-esteem, body-esteem, and perceived risk for developing chronic diseases) using validated questionnaires. Both VO2peak and muscle strength were significantly correlated with quality of life (r = 0.29, P < 0.01 and r = 0.30, P < 0.01, respectively), and quality of life subscales for: physical functioning (r = 0.28, P < 0.01 and r = 0.22, P < 0.05, respectively), pain (r = 0.18, P < 0.05 and r = 0.23, P < 0.05, respectively), role functioning (r = 0.20, P < 0.05 and r = 0.24, P < 0.05, respectively), and perceived risks (r = -0.24, P < 0.01 and r = -0.30, P < 0.01, respectively). In addition, VO2peak was significantly associated with positive health perceptions, greater body esteem, and less time watching television/video. Stepwise regression analysis showed that quality of life for health perceptions and for role functioning were independent predictors of VO2peak and muscle strength, respectively. In conclusion, higher VO2peak and muscle strength are associated with a favourable psychosocial profile, and the psychosocial correlates of VO2peak were different from those of muscle strength. Furthermore, psychosocial factors could be predictors of VO2peak and muscle strength in our cohort of overweight and obese sedentary post-menopausal women. PMID:18569559

    The objective of this cross-sectional study was to examine the relationship between the triglyceride-HDL-cholesterol ratio (TG:HDL-C) and insulin sensitivity in overweight and obese sedentary postmenopausal women. The study population consisted of 131 non-diabetic overweight and obese sedentary postmenopausal women (age; 57.7+/-5.0 y; body mass index (BMI), 32.2+/-4.3 kg/m2). Subjects were characterized by dividing the entire cohort into tertiles based on the TG:HDL-C (T1<0.86 vs. T2=0.86 to 1.35 vs. T3>1.35, respectively). We measured (i) insulin sensitivity (using the hyperinsulinenic-euglycemic clamp and homeostasis model assessment (HOMA)), (ii) body composition (using dual-energy X-ray absorptiometry), (iii) visceral fat (using computed tomography), (iv) plasma lipids, C-reactive protein, 2 h glucose concentration during an oral glucose tolerance test (2 h glucose), as well as fasting glucose and insulin, (v) peak oxygen consumption, and (vi) lower-body muscle strength (using weight training equipment). Significant correlations were observed between the TG:HDL-C and the hyperinsulinemic-euglycemic clamp (r=-0.45; p<0.0001), as well as with HOMA (r=0.42; p<0.0001). Moreover, the TG:HDL-C significantly correlated with lean body mass, visceral fat, 2 h glucose, C-reactive protein, and muscle strength. Stepwise regression analysis showed that the TG:HDL-C explained 16.4% of the variation in glucose disposal in our cohort, which accounted for the greatest source of unique variance. Other independent predictors of glucose disposal were 2 h glucose (10.1%), C-reactive protein (CRP; 7.6%), and peak oxygen consumption (5.8%), collectively (including the TG:HDL-C) explaining 39.9% of the unique variance. In addition, the TG:HDL-C was the second predictor for HOMA, accounting for 11.7% of the variation. High levels of insulin sensitivity were associated with low levels of the TG:HDL-C. In addition, the TG:HDL-C was a predictor for glucose disposal rates and HOMA values

    Latina women are vulnerable to poor body image, eating disorders, and obesity, particularly during the college years. This study sought to identify common cultural antecedents of these concerns in order to inform the development of prevention programs for this population. Six groups of university students who identified as Latina (N=27) discussed cultural aspects of body image, eating disorders, and obesity. Thematic analysis identified four main themes: (a) cultural disparities in body-ideal, including the influence of the media and acculturation issues; (b) messages about body shape and weight received by family, peers, and society; (c) difficulties making healthy eating and physical activity choices as a function of college life; and (d) the influence of peers and potential male partners on body satisfaction and body-ideals. These results have implications for the development of programs targeting body dissatisfaction and risk for eating disorders and obesity in Latina college women. PMID:22609033

    Over 80% of African-American (AA) women are overweight or obese. A large racial disparity between AA and European-Americans (EA) in obesity rates exists among women, but curiously not among men. Although socio-economic and/or cultural factors may partly account for this race-by-sex interaction, the potential involvement of genetic factors has not yet been investigated. Among 2814 self-identified AA in the Atherosclerosis Risk in Communities study, we estimated each individual's degree of West-African genetic ancestry using 3437 ancestry informative markers. We then tested whether sex modifies the association between West-African genetic ancestry and body mass index (BMI), waist-circumference (WC), and waist-to-hip ratio (WHR), adjusting for income and education levels, and examined associations of ancestry with the phenotypes separately in males and females. We replicated our findings in the Multi-Ethnic Study of Atherosclerosis (n = 1611 AA). In both studies, we find that West-African ancestry is negatively associated with obesity, especially central obesity, among AA men, but not among AA women (pinteraction = 4.14 × 10−5 in pooled analysis of WHR). In conclusion, our results suggest that the combination of male gender and West-African genetic ancestry is associated with protection against central adiposity, and suggest that the large racial disparity that exists among women, but not men, may be at least partly attributed to genetic factors.

    Suicidal behavior includes ideation, attempts and completed suicides. Information on suicidal behavior from Pakistan, a conservative South Asian Islamic country, is lacking. To address the issue, a pilot study was carried out to assess the prevalence of suicidal ideation in Pakistani college students. Suicidal ideation was assessed on the basis of responses to four questions contained in the depression subscale of the General Health Questionnaire-28. Of the total 217 completed questionnaires, the overall rate of suicidal ideation was 31.4%. While there was no significant difference between genders, more females (33%) than males (29.2%) responded positively. Respondents belonging to single parent families and those living at home, compared to those using hostel facilities, reported higher rates. The reported rate in our sample is higher than similar studies conducted elsewhere. There is the need for more information in this important area of suicidal behavior, including studying such feelings in school going children as well as in a larger community sample. The findings of such studies can contribute to our understanding of the suicidal process in the Pakistani population and to address it at various levels. PMID:16276755

    This study explored the effects of Health at Every Size(®)-based intervention on obese women by qualitatively evaluating participants' perception toward the program and quantitatively evaluating changes related to psychological, behavioral, and body composition assessments. A prospective 1-year quasi-experimental mixed-method trial was conducted. The mixed-method design was characterized by a spiral method, and quantitative and qualitative findings were combined during the interpretation phase. The qualitative data involved three focus groups; and quantitative data comprised physiological, psychological, and behavioral assessments. Initially, 30 participants were recruited; 14 concluded the intervention. From the focus groups, the following interpretative axes were constructed: the intervention as a period of discoveries; shifting parameters: psychological, physical, and behavioral changes; eating changes, and; redefining success. Body weight, body mass index, total body fat mass, and body fat percentage were significantly decreased after the intervention (-3.6, -3.2, -13.0, and -11.1%, respectively; p ≤ 0.05, within-time effect). Participants reported to be more physically active and perceiving better their bodies. Eating-wise, participants reported that the hunger and satiety cues and the consumption of more frequent meals facilitated their eating changes. Finally, participants reported that they could identify feelings with eating choices and refrain from the restrained behavior. These qualitative improvements were accompanied by modest but significant improvements in quantitative assessments. Clinicaltrials.gov registration: NCT02102061. PMID:26579524

    Because obesity is frequently complicated by other cardiovascular risk factors, the impact of a reduction in visceral adiposity on vascular endothelial dysfunction (VED) in obese patients is difficult to determine. In the present study, we evaluated the impact of a reduction in visceral adiposity on VED in obese women. Thirty-six premenopausal obese women (BMI >/= 25 kg/m2) without complications were enrolled in the study. VED was evaluated by determining the augmentation index (AIx) from radial artery pulse waves obtained by applanation tonometry. Changes in AIx in response to nitroglycerin- induced endothelium-independent vasodilatation (DeltaAIx-NTG) and in response to salbutamol administration (DeltaAIx-Salb) were determined before and after weight reduction. After a 12-week weight reduction program, the average weight loss was 7.96 +/- 3.47 kg, with losses of 21.88 +/- 20.39 cm2 in visceral fat areas (p < 0.001). Pulse wave analysis combined with provocative pharmacological testing demonstrated preserved endothelium-independent vasodilation in healthy premenopausal obese women (DeltaAIx-NTG: 31.36 +/- 9.80% before weight reduction vs. 28.25 +/- 11.21% after weight reduction, p > 0.1) and an improvement in endothelial-dependent vasodilation following weight reduction (DeltaAIx-Salb: 10.03 +/- 6.49% before weight reduction vs. 19.33 +/- 9.28% after reduction, p < 0.001). A reduction in visceral adipose tissue was found to be most significantly related to an increase in DeltaAIx-Salb (beta=-0.57, p < 0.001). A reduction in visceral adiposity was significantly related to an improvement in VED. This finding suggests that reduction of visceral adiposity may be as important as the control of other major risk factors in the prevention of atherosclerosis in obese women. PMID:16127776

    Objective This study explored fast food intake as a potential mediator of the relationships among employment status; stress; depression; and fruit, vegetable, and fat intakes by race (African American vs. Non-Hispanic White) and body mass index (BMI category: overweight vs. obesity). Methods Low-income overweight and obese pregnant women (N = 332) were recruited from the Special Supplemental Nutrition Program for Women, Infants and Children in Michigan. Path analysis was performed to explore mediation effects by race and BMI category. Results Fast food intake mediated the relationship between employment status and fat intake (p = 0.02) in Non-Hispanic White women, but no mediation effect was detected in African American women. For overweight women, fast food intake mediated the relationship between employment status and fat intake (p = 0.04) and the relationship between depression and vegetable intake (p = 0.01). Also, fast food intake partially mediated the relationship between depression and fat intake (p = 0.003). For obese women, fast food intake mediated the relationship between employment status and fat intake (p = 0.04). Conclusion Fast food is an important topic for nutrition education for overweight and obese pregnant women. Future interventions may be more successful if they address issues associated with employment status (e.g., lack of time to plan and cook healthy meals) and depressive mood (e.g., inability to plan meals or shop for groceries when coping with negative emotions).

    The incidence of maternal obesity and its co-morbidities (diabetes, cardiovascular disease) continues to increase at an alarming rate, with major public health implications. In utero exposure to maternal obesity has been associated with development of cardiovascular and metabolic diseases in the offspring as a result of developmental programming. The placenta regulates maternal-fetal metabolism and shows significant changes in its function with maternal obesity. Autophagy is a cell-survival process, which is responsible for the degradation of damaged organelles and misfolded proteins. Here we show an activation of autophagosomal formation and autophagosome-lysosome fusion in placentas of males but not females from overweight (OW) and obese (OB) women vs. normal weight (NW) women. However, total autophagic activity in these placentas appeared to be decreased as it showed an increase in SQSTM1/p62 and a decrease in lysosomal biogenesis. A mouse model with a targeted deletion of the essential autophagy gene Atg7 in placental tissue showed significant placental abnormalities comparable to those seen in human placenta with maternal obesity. These included a decrease in expression of mitochondrial genes and antioxidants, and decreased lysosomal biogenesis. Strikingly, the knockout mice were developmentally programmed as they showed an increased sensitivity to high-fat diet-induced obesity, hyperglycemia, hyperinsulinemia, increased adiposity, and cardiac remodeling. In summary, our results indicate a sexual dimorphism in placental autophagy in response to maternal obesity. We also show that autophagy plays an important role in placental function and that inhibition of placental autophagy programs the offspring to obesity, and to metabolic and cardiovascular diseases.

    ABSTRACT Objectives The purpose of the study was to identify the risk of orofacial cleft in the offspring of women with pre-maternal obesity/overweight when compared with pre-maternal normal weight women. Material and Methods MEDLINE and EMBASE were searched from 1980 to July 2014 for cohort, case control and cross sectional studies. BMI were categorized according to WHO recommendation: normal weight (BMI 18.5 - 24.9), overweight (BMI 25 - 29.9) and obese (BMI ≥ 30). Results Six studies were identified; three case control studies which were used for the meta-analysis and two cross sectional studies and one cohort study. Compared with women of recommended BMI, obese women were at increased odds of pregnancy affected by CLP (OR = 1.16; 95% CI 1, 1.34) and CP (OR = 1.14; 95% CI 0.95, 1.37). Overweight women were also at increased odds of pregnancy affected by CLP (OR = 1.06; 95% CI 0.93, 1.21) but not CP (OR = 0.89; 95% CI 0.75, 1.06). The results of the risk ratios reported in the cross sectional and cohort studies were similar to the results of the meta-analysis. Conclusions The results of this study reveal that there is an increased risk of having offspring with orofacial cleft in obese/overweight women. The reason for this association is not known. Although, the risk is small, it is important because of the increasing incidence of obesity. PMID:25937872

    Irisin has recently been proposed to act as a myokine secreted from skeletal muscle following exercise and to exert several health-beneficial effects, although its role is far from being established. In contrast to the growing body of literature on the biological regulation and function of irisin, there is no evidence on potential associations with mental functions. Since physical activity has been reported to have favorable impact on mental functions, we investigated the association of irisin with depressiveness, perceived stress, and anxiety as well as eating disorder symptoms in obese women. We included 98 female obese inpatients (age: mean ± S.D. 43.9 ± 12.5 years; body mass index 49.2 ± 8.3 kg/m(2)) covering a broad spectrum of psychopathology. Depressiveness (PHQ-9), perceived stress (PSQ-20), anxiety (GAD-7), and eating disorder symptoms (EDI-2) were assessed psychometrically. Plasma irisin obtained at the same time was determined by ELISA. Irisin did not correlate with depressiveness (r = -0.03, P = 0.80), anxiety (r = 0.14, P = 0.17) and perceived stress (r = -0.14, P = 0.18) as well as eating disorder symptoms in general (r = -0.09, P = 0.39). No correlation of irisin was observed with any subscales of the PSQ-20 and EDI-2 (after Bonferroni correction). In conclusion, irisin is not associated with depressiveness, anxiety and perceived stress in female obese patients. These results do not support the assumption of irisin being involved in psychoendocrine pathways of the regulation of depression or other mental functions such as anxiety and perceived stress.

    In the Western world, the diagnosis and management of Plasmodium vivax malaria in pregnant women can be challenging, and the pathogenesis of adverse outcomes for both the mother and the foetus is still poorly known. The authors describe the case of a 29-year-old Pakistani woman at the 29th week of her second pregnancy, who was admitted to the Hospital following the abrupt onset of fever. At the time of admission, she had been living in Italy without travelling to any malaria-endemic areas for eight months. She was diagnosed with vivax malaria after a thin blood smear revealed the presence of plasmodial trophozoites and gametocytes and treated accordingly. Due to the onset of oligohydramnios, she underwent caesarian section at the 31st week of pregnancy with no further complications. Histological examination of the placenta showed no evidence of plasmodial infection, but was inconclusive. It is unclear whether oligohydramnios is a complication of pregnancy-related Plasmodium vivax malaria. Given the long latency of hypnozoites, every febrile pregnant patient with a previous stay in an endemic area should be screened for malaria with a thick and a thin blood smear. PMID:24758193

    Gene expression (qPCR) was compared in round ligament (RL), omental (OME) and mesenteric (MES) ATs from 48 severely obese women (BMI, 54±11 kg/m(2); 38±9 yrs). The mRNA levels of enzymes of lipid metabolism (LPL, HSL, and PDE-3B), cortisol production (11βHSD-1), adipogenesis (PPAR-γ1/2), thrombosis and inflammation (PAI-1, IL-6, TNF-α and adiponectin) were determined. AT-LPL mRNA was highest in RL. The highest PDE-3B and lowest PAI-1 mRNA levels were observed in RL and MES. The lowest IL-6 and TNF-α and the highest adiponectin and PPAR-g1/2 mRNA levels were found in RL AT. 11βHSD-1 was highest in RL and OME. A higher lipogenic and adipogenic, and lower pro-inflammatory and pro-thrombotic profiles of the RL suggest a lesser deleterious impact on obesity-related complications. PMID:27144094

    Recent reports suggest a role for the Patatin-like phospholipase domain-containing protein 3 (PNPLA3) in the pathology of non-alcoholic fatty liver disease (NAFLD). Lipid deposition in the liver seems to be a critical process in the pathogenesis of NAFLD. The aim of the present work was to evaluate the association between the liver PNPLA3 expression, key genes of lipid metabolism, and the presence of NAFLD in morbidly obese women. We used real-time polymerase chain reaction (PCR) analysis to analyze the hepatic expression of PNPLA3 and lipid metabolism-related genes in 55 morbidly obese subjects with normal liver histology (NL, n = 18), simple steatosis (SS, n = 20), and non-alcoholic steatohepatitis (NASH, n = 17). Liver biopsies were collected during bariatric surgery. We observed that liver PNPLA3 expression was increased in NAFLD than in NL. It was also upregulated in SS than in NL. Interestingly, we found that the expression of PNPLA3 was significantly higher in severe than mild SS group. In addition, the expression of the transcription factors LXRα, PPARα, and SREBP2 was positively correlated with PNPLA3 liver expression. Regarding rs738409 polymorphism, GG genotype was positive correlated with the presence of NASH. In conclusion, our results show that PNPLA3 could be related to lipid accumulation in liver, mainly in the development and progression of simple steatosis. PMID:27128907

    Recent reports suggest a role for the Patatin-like phospholipase domain-containing protein 3 (PNPLA3) in the pathology of non-alcoholic fatty liver disease (NAFLD). Lipid deposition in the liver seems to be a critical process in the pathogenesis of NAFLD. The aim of the present work was to evaluate the association between the liver PNPLA3 expression, key genes of lipid metabolism, and the presence of NAFLD in morbidly obese women. We used real-time polymerase chain reaction (PCR) analysis to analyze the hepatic expression of PNPLA3 and lipid metabolism-related genes in 55 morbidly obese subjects with normal liver histology (NL, n = 18), simple steatosis (SS, n = 20), and non-alcoholic steatohepatitis (NASH, n = 17). Liver biopsies were collected during bariatric surgery. We observed that liver PNPLA3 expression was increased in NAFLD than in NL. It was also upregulated in SS than in NL. Interestingly, we found that the expression of PNPLA3 was significantly higher in severe than mild SS group. In addition, the expression of the transcription factors LXRα, PPARα, and SREBP2 was positively correlated with PNPLA3 liver expression. Regarding rs738409 polymorphism, GG genotype was positive correlated with the presence of NASH. In conclusion, our results show that PNPLA3 could be related to lipid accumulation in liver, mainly in the development and progression of simple steatosis. PMID:27128907

    Objective To evaluate whether a 12-week supervised exercise program promotes an active lifestyle throughout pregnancy in pregnant women with obesity. Methods In this preliminary randomised trial, pregnant women (body mass index ≥ 30 kg/m2) were allocated to either standard care or supervised training, from 15 to 27 weeks of gestation. Physical activity was measured by accelerometry at 14, 28 and 36 weeks, while fitness (oxygen consumption (VO2) at the anaerobic threshold), nutrition (caloric intake and macronutrients percentage) and anthropometry were assessed at 14 and 28 weeks of gestation. Analyses were performed using repeated measures ANOVA. Results A total of fifty (50) women were randomised, 25 in each group. There was no time-group interaction for time spent at moderate and vigorous activity (pinteraction = 0.064), but the exercise group’s levels were higher than controls’ at all times (pgroup effect = 0.014). A significant time-group interaction was found for daily physical activity (p = 0.023); similar at baseline ((22.0 ± 6.7 vs 21.8 ± 7.3) x 104 counts/day) the exercise group had higher levels than the control group following the intervention ((22.8 ± 8.3 vs 19.2 ± 4.5) x 104 counts/day, p = 0.020) and at 36 weeks of gestation ((19.2 ± 1.5 vs 14.9 ± 1.5) x 104 counts/day, p = 0.034). Exercisers also gained less weight than controls during the intervention period despite similar nutritional intakes (difference in weight change = -0.1 kg/week, 95% CI -0.2; -0.02, p = 0.016) and improved cardiorespiratory fitness (difference in fitness change = 8.1%, 95% CI 0.7; 9.5, p = 0.041). Conclusions Compared with standard care, a supervised exercise program allows pregnant women with obesity to maintain fitness, limit weight gain and attenuate the decrease in physical activity levels observed in late pregnancy.

    1. In the present study, we conducted the first randomized, double-blind, placebo-controlled study of bofu-tsusho-san (BF), an oriental herbal medicine (24 mg/day ephedrine in Ephedrae Herba and an efficacy equivalent of 280 mg caffeine, judging from the phosphodiesterase-inhibitory effect of Glycyrrhizae Radix, Forsythiae Fructus and Schizonepetae Spica and another 14 crude drugs) in obese women with impaired glucose tolerance (IGT). 2. The aim of the present study was to determine whether BF was effective in decreasing visceral adiposity and insulin resistance. Eighty-one Japanese women (body mass index (BMI) 36.5 +/- 4.8 kg/m2) with IGT and insulin resistance (IR), who had been treated with a low-calorie diet (5016 kj/day: 1200 kcal) and an exercise regimen (1254 kj/day: 300 kcal), were randomized to receive either placebo (n=40) or BF treatment (n=41) three times a day. 3. After 24 weeks treatment, the BF group lost significantly (P <0.01) more bodyweight and abdominal visceral fat without a decrease in the adjusted resting metabolic rate (RMR), whereas the placebo group lost bodyweight (P <0.05) and had no significant change in abdominal visceral fat. The BF group had a lower fasting serum insulin level (P <0.05), a lower insulin area under the curve (P <0.05) and a lower level of the homeostasis model assessment of insulin resistance (P <0.01) compared with values before treatment. 4. We conclude that BF could be a useful herbal medicine in treating obesity with IGT. PMID:15479169

  17. Intermittent fasting combined with calorie restriction is effective for weight loss and cardio-protection in obese women

    Background Intermittent fasting (IF; severe restriction 1 d/week) facilitates weight loss and improves coronary heart disease (CHD) risk indicators. The degree to which weight loss can be enhanced if IF is combined with calorie restriction (CR) and liquid meals, remains unknown. Objective This study examined the effects of IF plus CR (with or without a liquid diet) on body weight, body composition, and CHD risk. Methods Obese women (n = 54) were randomized to either the IFCR-liquid (IFCR-L) or IFCR-food based (IFCR-F) diet. The trial had two phases: 1) 2-week weight maintenance period, and 2) 8-week weight loss period. Results Body weight decreased more (P = 0.04) in the IFCR-L group (3.9 ± 1.4 kg) versus the IFCR-F group (2.5 ± 0.6 kg). Fat mass decreased similarly (P < 0.0001) in the IFCR-L and IFCR-F groups (2.8 ± 1.2 kg and 1.9 ± 0.7 kg, respectively). Visceral fat was reduced (P < 0.001) by IFCR-L (0.7 ± 0.5 kg) and IFCR-F (0.3 ± 0.5 kg) diets. Reductions in total and LDL cholesterol levels were greater (P = 0.04) in the IFCR-L (19 ± 10%; 20 ± 9%, respectively) versus the IFCR-F group (8 ± 3%; 7 ± 4%, respectively). LDL peak particle size increased (P < 0.01), while heart rate, glucose, insulin, and homocysteine decreased (P < 0.05), in the IFCR-L group only. Conclusion These findings suggest that IF combined with CR and liquid meals is an effective strategy to help obese women lose weight and lower CHD risk. PMID:23171320

    Overeating is believed to result when the appetitive motivation to consume palatable food exceeds an individual’s capacity for inhibitory control of eating. This hypothesis was supported in recent studies involving predominantly normal weight women, but has not been tested in obese populations. The current study tested the interaction between food reward sensitivity and inhibitory control in predicting palatable food intake among energy-replete overweight and obese women (N=62). Sensitivity to palatable food reward was measured with the Power of Food Scale. Inhibitory control was assessed with a computerized choice task that captures the tendency to discount large delayed rewards relative to smaller immediate rewards. Participants completed an eating in the absence of hunger protocol in which homeostatic energy needs were eliminated with a bland preload of plain oatmeal, followed by a bogus laboratory taste test of palatable and bland snacks. The interaction between food reward sensitivity and inhibitory control was a significant predictor of palatable food intake in regression analyses controlling for body mass index and the amount of preload consumed. Probing this interaction indicated that higher food reward sensitivity predicted greater palatable food intake at low levels of inhibitory control, but was not associated with intake at high levels of inhibitory control. As expected, no associations were found in a similar regression analysis predicting intake of bland foods. Findings support a neurobehavioral model of eating behavior in which sensitivity to palatable food reward drives overeating only when accompanied by insufficient inhibitory control. Strengthening inhibitory control could enhance weight management programs. PMID:21475139

    This review discusses the factors involved in the aetiology of obesity. The effect of dietary macronutrient composition on the metabolic fate of fat (oxidation or storage) is emphasised. Available information on dietary intake in adults from food balance sheets or dietary surveys, show that females eat a relatively low amount of fat (50-70 g/d on average), although this seems to be rising. The increasing prevalence of obesity in our population could be related to the glycemic index of meals, their fatty acid composition and the time interval between meals. This paper compares the oxidation rates of different fatty acids, particularly polyunsaturated fatty acids (PUFA), and among these, the high oxidation rates found for alpha-linolenic and linoleic acids. Medium chain saturated fatty acids (C8 to C12) are more likely to be oxidised in comparison with PUFA and longer chain saturated fatty acids. The latter are more likely to be directed to fat storage, particularly when they are combined with highly glycemic carbohydrates (CHO) in the same meal. Given the large proportion of CHO in the usual diet, the relevance of de-novo lipogenesis from CHO is questioned. It is concluded that this route is not readily used in humans consuming normal diets. Therefore, this mechanism can not be responsible for the rising prevalence of obesity. PMID:10752279

    We surveyed overweight or obese women receiving prenatal care for a singleton pregnancy at a large academic medical center in 2010. During late pregnancy, women reported pregnancy intentionality and pre-conception weight counseling. Participants (N = 82) had a mean age of 29.7 (SD: 6.3) years, 61% were non-Hispanic white, 47% were nulliparous. Before pregnancy, 45% were overweight and 55% were obese. Forty-eight percent reported that the current pregnancy was planned. Of these women, 36% reported a pre-conception visit. Of these, 29% reported pre-conception weight counseling (5% of sample). Unrealized opportunities exist in the clinical setting for promoting weight management during the childbearing years. PMID:25998880

    Maternal obesity is associated to increased fetal risk of obesity and other metabolic diseases. Human amniotic mesenchymal stem cells (hA-MSCs) have not been characterized in obese women. The aim of this study was to isolate and compare hA-MSC immunophenotypes from obese (Ob-) and normal weight control (Co-) women, to identify alterations possibly predisposing the fetus to obesity. We enrolled 16 Ob- and 7 Co-women at delivery (mean/SEM prepregnancy body mass index: 40.3/1.8 and 22.4/1.0 kg/m2, respectively), and 32 not pregnant women. hA-MSCs were phenotyped by flow cytometry; several maternal and newborn clinical and biochemical parameters were also measured. The expression of membrane antigen CD13 was higher on Ob-hA-MSCs than on Co-hA-MSCs (P=0.005). Also, serum levels of CD13 at delivery were higher in Ob- versus Co-pregnant women and correlated with CD13 antigen expression on Ob-hA-MSCs (r2=0.84, P<0.0001). Adipogenesis induction experiments revealed that Ob-hA-MSCs had a higher adipogenic potential than Co-hA-MSCs as witnessed by higher peroxisome proliferator-activated receptor gamma and aP2 mRNA levels (P=0.05 and P=0.05, respectively), at postinduction day 14 associated with increased CD13 mRNA levels from baseline to day 4 postinduction (P<0.05). Adipogenesis was similar in the two sets of hA-MSCs after CD13 silencing, whereas it was increased in Co-hA-MSCs after CD13 overexpression. CD13 expression was high also in Ob-h-MSCs from umbilical cords or visceral adipose tissue of not pregnant women. In conclusion, antigen CD13, by influencing the adipogenic potential of hA-MSCs, could be an in utero risk factor for obesity. Our data strengthen the hypothesis that high levels of serum and MSC CD13 are obesity markers. PMID:23488598

    Poor sleep quality and short sleep duration are associated with increased incidence and progression of a number of chronic health conditions observed at greater frequency among the obese and those experiencing high levels of stress. Accelerated cellular aging, as indexed by telomere attrition in immune cells, is a plausible pathway linking sleep and disease risk. Prior studies linking sleep and telomere length are mixed. One factor may be reliance on leukocytes, which are composed of varied immune cell types, as the sole measure of telomere length. To better clarify these associations, we investigated the relationships of global sleep quality, measured by the Pittsburgh Sleep Quality Index (PSQI), and diary-reported sleep duration with telomere length in different immune cell subsets, including granulocytes, peripheral blood mononuclear cells (PBMCs), CD8+ and CD4+ T lymphocytes, and B lymphocytes in a sample of 87 obese men and women (BMI mean=35.4, SD=3.6; 81.6% women; 62.8% Caucasian). Multiple linear regression analyses were performed adjusting for age, gender, race, education, BMI, sleep apnea risk, and perceived stress. Poorer PSQI global sleep quality was associated with statistically significantly shorter telomere length in lymphocytes but not granulocytes and in particular CD8+ T cells (b=-56.8 base pairs per one point increase in PSQI, SE=20.4, p=0.007) and CD4+ T cells (b=-37.2, SE=15.9, p=0.022). Among separate aspects of global sleep quality, low perceived sleep quality and decrements in daytime function were most related to shorter telomeres. In addition, perceived stress moderated the sleep-CD8+ telomere association. Poorer global sleep quality predicted shorter telomere length in CD8+ T cells among those with high perceived stress but not in low stress participants. These findings provide preliminary evidence that poorer global sleep quality is related to telomere length in several immune cell types, which may serve as a pathway linking sleep and

    The synthesis of serotonin at CNS level is influenced by diet. Moreover, insulin resistance is associated with lower serotonin levels. Visceral obesity, strictly linked to hepatic steatosis is specifically associated with mild to severe somatic affective-depressive symptom clusters. Previous data support the view that depression involves serotonergic systems, reflecting low levels of urinary 5- hydroxy-3-indoleacetic acid (5-HIAA). The 24-h urinary excretion of 5-HIAA was evaluated in 76 dystimic/depressed, obese/overweight females, divided into two groups, i.e., on a hyper-caloric diet, associated with a life style characterized by leisure time sedentary behavior (LTSB, 35 women), or on a normo-caloric diet, assisted by program-based strategies aimed at promoting physical activity participation (PAP, 41 women). Beck Depression Inventory (BDI) was carried out to score the severity of dystimia/depression. Anthropometric measures, metabolic indices, severity of hepatic steatosis at sonography and HOMA were studied. Urinary levels of 5-HIAA in controls and PAP groups were comparable with a great overlap, while in the LTSB group the urinary excretion of 5-HIAA was significantly reduced in respect to that of the PAP group and obviously compared to that of the control group, 3.4±1.4 mg/L versus 6.2±2.7 mg/L and 6.4±2.6 mg/L, respectively, ANOVA test, P= 0.001. Among metabolic indices, cholesterol, HDL-cholesterol, triglycerides and uric acid were not able to predict urinary concentrations of 5-HIAA, which were not associated with hepatic steatosis; vice versa, ferritin levels, and mainly HOMA values, were independent predictors of the urinary excretion of 5-HIAA (β=0.235 and 0.45, respectively). Dystimia/depression severity was negatively predicted by urinary 5-HIAA levels in the sense that the highest BDI values were forecast by the lowest values of urinary 5-HIAA (β= -0.72).The importance of measuring the 24-h urinary excretion of 5-HIAA in follow-ups could rely

    This study was conducted to identify factors that influenced stress, healthy eating and physical activity among low-income overweight or obese pregnant women. We conducted seven focus groups with 96 low-income overweight and obese pregnant women. Common themes were identified from audio tapes and transcripts. Women said that poor communication affected their relationships with spouses or significant others. They were frustrated or upset with significant others for three key reasons: failure to understand or listen to the pregnant women's pregnancy concerns, refusal to be helpful when asked and being overly concerned with the woman's safety. Most women said that they were emotional and took naps throughout the day after becoming pregnant. Many withdrew from their social interactions. They also faced numerous challenges that made healthy eating more difficult, e.g., craving for unhealthy foods and eating foods for comfort. To eat healthier, some reminded themselves to avoid overeating or stop eating in the car. Women were not physically active because of tiredness, lack of motivation, inadequate social support, or bad weather. Some stayed physically active to prevent excessive pregnancy weight gain and have an easier labor. Women equivocally said weighing themselves to manage weight would add to their stress and make them feel more depressed. When designing interventions to help low-income overweight and obese pregnant women avoid excessive pregnancy weight gain, it is important to include information and practical advice on stress management, emphasizing effective communication skills with significant others and helping them plan effective ways to manage negative feelings.

    Objective To highlight the contribution of the gut microbiota to the modulation of host metabolism by dietary inulin-type fructans (ITF prebiotics) in obese women. Methods A double blind, placebo controlled, intervention study was performed with 30 obese women treated with ITF prebiotics (inulin/oligofructose 50/50 mix; n=15) or placebo (maltodextrin; n=15) for 3 months (16 g/day). Blood, faeces and urine sampling, oral glucose tolerance test, homeostasis model assessment and impedancemetry were performed before and after treatment. The gut microbial composition in faeces was analysed by phylogenetic microarray and qPCR analysis of 16S rDNA. Plasma and urine metabolic profiles were analysed by 1H-NMR spectroscopy. Results Treatment with ITF prebiotics, but not the placebo, led to an increase in Bifidobacterium and Faecalibacterium prausnitzii; both bacteria negatively correlated with serum lipopolysaccharide levels. ITF prebiotics also decreased Bacteroides intestinalis, Bacteroides vulgatus and Propionibacterium, an effect associated with a slight decrease in fat mass and with plasma lactate and phosphatidylcholine levels. No clear treatment clustering could be detected for gut microbial analysis or plasma and urine metabolomic profile analyses. However, ITF prebiotics led to subtle changes in the gut microbiota that may importantly impact on several key metabolites implicated in obesity and/or diabetes. Conclusions ITF prebiotics selectively changed the gut microbiota composition in obese women, leading to modest changes in host metabolism, as suggested by the correlation between some bacterial species and metabolic endotoxaemia or metabolomic signatures.

    Recent studies have suggested that excessive intake of dietary fat is associated with obesity. Some obese subjects have been reported to exhibit high thresholds for the gustatory detection of lipids via lipid receptors, such as cluster of differentiation 36 (CD36). We studied lingual detection thresholds for emulsions containing oleic acid in obese Tunisian women (n 203) using a three-alternative forced choice (3-AFC) method. Genotyping of the TNF-α (rs1800629), IL-6 (rs1800795) and CD36 (rs1761667) genes was performed to associate with lipid taste perception thresholds. The CD36 genotype distribution was as follows: GG (n 42), AG (n 102) and AA (n 59). Women with the CD36 GG genotype exhibited oral detection thresholds for oleic acid that were more than three times lower than those with the CD36 AA genotype. The present study confirms a high threshold of gustatory fat detection in obese women with the CD36 AA genotype, but there is no significant association with the IL-6 and TNF-α gene polymorphisms.

    The rapidly increasing prevalence of both obesity and depression represent two major public health concerns worldwide. But the evidence regarding the direction and strength of the association between these two disorders, for both adult men and women, are remain inconclusive. We systematically reviewed publications from five different databases: Pubmed, Embase, BIOSIS, CINAHL and PsychINFO. A total of 21 articles were included for the systematic review and 19 of them for the meta-analysis using a bias-adjusted (quality effect) model. This resulted in the inclusion of approximately 226,063 (33.7% men) participants. Those who were depressed had a 37% (RR: 1.37, 95% CI: 1.17, 1.48) increased risk of being obese, and who were obese had an 18% increased risk of being depressed (RR: 1.18, 95% CI: 1.04, 1.35). Those who were depressed had a 2% (RD: 0.02, 95% CI: 0.01, 0.03) excess risk of obesity, however, the reciprocal associations were not significant. The association between overweight and depression was not found significant in either direction. Both men and women were at risk of obesity and depression bi-directionally. In sensitivity analyses bi-directional associations were more pronounced among young and middle aged adults and in studies with longer follow-up. The findings of this study suggest that the strength of the association is greater for the direction leading from depression to obesity and this link was more pronounced for young and middle aged women.

    The incidence of breast cancer is increasing worldwide, and this seems to be related to an increase in lifestyle risk factors, including physical inactivity and overweight/obesity. We have reported previously that exercise induced a circulating angiostatic phenotype characterized by increased soluble fms-like tyrosine kinase-1 (sFlt-1) and endostatin and decreased unbound vascular endothelial growth factor (VEGF) in men. However, there are no data on women. The present study determines the following: (a) whether moderate exercise increased sFlt-1 and endostatin and decreased unbound VEGF in the circulation of adult female volunteers and (b) whether overweight/obese women have a higher plasma level of unbound VEGF than lean women. A total of 72 African American and White adult women volunteers ranging in age from 18 to 44 years were enrolled in the exercise study. All the participants walked on a treadmill for 30 min at a moderate intensity (55-59% heart rate reserve), and oxygen consumption (VO(2)) was quantified utilizing a metabolic cart. We obtained blood samples before and immediately after exercise from 63 participants. ELISA assays showed that the plasma levels of sFlt-1 were 67.8±3.7 pg/ml immediately after exercise (30 min), significantly higher than the basal levels, 54.5±3.3 pg/ml, before exercise (P<0.01; n=63). There was no significant difference in the % increase in the sFlt-1 levels after exercise between African American and White (P=0.533) women or between lean and overweight/obese women (P=0.892). There was no significant difference in the plasma levels of unbound VEGF (35.28±5.47 vs. 35.23±4.96 pg/ml; P=0.99) or endostatin (111.12±5.48 vs. 115.45±7.15 ng/ml; P=0.63) before and after exercise. The basal plasma levels of unbound VEGF in overweight/obese women were 52.26±9.6 pg/ml, significantly higher than the basal levels of unbound VEGF in lean women, 27.34±4.99 pg/ml (P<0.05). The results support our hypothesis that exercise

    Human ether-a-go-go-related gene (hERG) potassium channels determine cardiac action potential and contraction duration. Human uterine contractions are underpinned by an action potential that also possesses an initial spike followed by prolonged depolarization. Here we show that hERG channel proteins (α-conducting and β-inhibitory subunits) and hERG currents exist in isolated patch-clamped human myometrial cells. We show that hERG channel activity suppresses contraction amplitude and duration before labour, thereby facilitating quiescence. During established labour, expression of β-inhibitory protein is markedly enhanced, resulting in reduced hERG activity that is associated with an increased duration of uterine action potentials and contractions. Thus, changes in hERG channel activity contribute to electrophysiological mechanisms that produce contractions during labour. We also demonstrate that this system fails in women with elevated BMI, who have enhanced hERG activity as a result of low β-inhibitory protein expression, which likely contributes to the weak contractions and poor labour outcomes observed in many obese women necessitating caesarean delivery.

    In Pakistan majority of the consumers do not have information about genetically modified (GM) foods. In developing countries particularly in Pakistan few studies have focused on consumers' acceptability about GM foods. Using comprehensive primary dataset collected from 320 consumers in 2013 from Pakistan, this study analyzes the determinants of consumers' acceptability of GM foods. The data was analyzed by employing the bivariate probit model and censored least absolute deviation (CLAD) models. The empirical results indicated that urban consumers are more aware of GM foods compared to rural consumers. The acceptance of GM foods was more among females' consumers as compared to male consumers. In addition, the older consumers were more willing to accept GM food compared to young consumers. The acceptability of GM foods was also higher among wealthier households. Low price is the key factor leading to the acceptability of GM foods. The acceptability of the GM foods also reduces the risks among Pakistani consumers. PMID:27494790

    Background: The optimal diet for pregnancy that is complicated by excessive weight is unknown. Objective: We aimed to examine the effects of a low–glycemic load (low-GL) diet in overweight and obese pregnant women. Design: We randomly assigned 46 overweight or obese pregnant women to receive a low-GL or a low-fat diet. Participants received carbohydrate-rich foods, fats, and snack foods through home delivery or study visits. The primary outcome was birth weight z score. Other endpoints included infant anthropometric measurements, gestational duration, maternal weight gain, and maternal metabolic parameters. Results: There were no significant differences in birth weight z score or other measures of infant adiposity between groups. However, in the low-GL compared with the low-fat group, gestational duration was longer (mean ± SD: 39.3 ± 1.1 compared with 37.9 ± 3.1 wk; P = 0.05) and fewer deliveries occurred at ≤38.0 wk (13% compared with 48%, P = 0.02; with exclusion of planned cesarean deliveries: 5% compared with 53%; P = 0.002). Adjusted head circumference was greater in the low-GL group (35.0 ± 0.8 compared with 34.2 ± 1.3 cm, P = 0.01). Women in the low-GL group had smaller increases in triglycerides [median (interquartile range): 49 (19, 70) compared with 93 (34, 129) mg/dL; P = 0.03] and total cholesterol [13 (0, 36) compared with 33 (22, 56) mg/dL, P = 0.04] and a greater decrease in C-reactive protein [−2.5 (−5.5, −0.7) compared with −0.4 (−1.4, 1.5) mg/dL, P = 0.007]. Conclusions: A low-GL diet resulted in longer pregnancy duration, greater infant head circumference, and improved maternal cardiovascular risk factors. Large-scale studies are warranted to evaluate whether dietary intervention during pregnancy aimed at lowering GL may be useful in the prevention of prematurity and other adverse maternal and infant outcomes. This trial is registered at clinicaltrials.gov as NCT00364403. PMID:20962162

    A follow-up study was conducted to re-evaluate a group of obese middle-aged women (n = 13), eight of whom had completed an 18-wk supervised (3 d/wk) plus unsupervised (2 d/wk) conditioning intervention program (at least 90 min per day) as the exercise plus diet group; while five of the remainder served as the control group. Each session had included a 25- to 45-min jog/run at intensities between the heart rate (HR) corresponding to lactate threshold (LT) and that slightly above the HR @ LT. During 1 year following the program, the women participated in self-controlled training such as running, aerobic dancing, or jazz dancing 2.6 +/- 1.1 d/wk. Dietary intake averaged approximately 1736 +/- 152 kcal/d at the pre-treatment, 1404 +/- 124 kcal/d at the post-treatment, and 1645 +/- 147 kcal/d 1 year after the post-treatment. Interestingly however, oxygen uptake corresponding to LT (VO2 @ LT), maximal oxygen uptake (VO2max), weight, systolic blood pressure, and the ratio of high-density lipoprotein cholesterol to total cholesterol (HDLC/TC) observed 1 year after the post-treatment were significantly different from the original pre-treatment and/or mid-treatment values. For instance, the significant 42% increase (14.7 +/- 2.4----21.3 +/- 4.2 ml/kg/min) in VO2 @ LT and 18% increase (0.284 +/- 0.106----0.335 +/- 0.093) in HDLC/TC from the pre-test to post-test were maintained throughout the 1-year follow-up period, suggesting no detrimental effect either on a cardiorespiratory fitness factor or on an anti-atherogenic factor. These findings indicate that physiologic status of obese middle-aged women engaged in a conditioning intervention program may not regress to pre-treatment status for at least one year after completion; provided they continue to participate in a 2.6-d/wk self-controlled training program with dietary intake of 1600-1700 kcal/d. Another interesting finding was that significant relationships existed between individual changes (delta) in training frequency

    This study observed the effect of a dietary re-education plus regular physical activity on body composition, risk factors and physical test performance of sedentary overweight/obese women and to correlate these variables one with each other. Fifty women (36 ± 10 yrs; 31 ± 6 body mass index (BMI, kg/m2)) volunteered for the study. Body compositions were obtained by anthropometry and bioimpedance and some body indexes were established. One-repetition maximum (1-RM) and treadmill VO2max tests were carried out and blood samples were obtained for lipid, glucose and uric acid analyses before (T1) and after two months of intervention (T2). Diet was established by indirect calorimetry. Body fat, glucose, uric acid, total cholesterol, HDL-cholesterol and systolic blood pressure were significantly reduced. The 1-RM and VO2max tests were significantly increased. Neck circumference (NC) was correlated with body composition, back muscle 1-MR, HDL and LDL cholesterol, total cholesterol/HDL ratio, uric acid, and resting energy expenditure. BMI was found to be significantly correlated with waist/hip ratio, circumference sum, and body fat percentage by anthropometry and bioimpedance. Body fat percentage determined by bioimpedance and anthropometry was significantly correlated with arm fat area and arm fat area corrected respectively, and both with BMI at T1 and T2. This study suggests that a dietary reeducation plus physical activity around 200 min/week improved body composition and the health of these women. Many anthropometry measurements have correspondence to risk factors and NC could be a simple approach to reflect these results, without other more complex techniques. PMID:18500956

    Unhealthy lifestyle behaviours are known modifiable risk factors for cardiovascular disease (CVD). This cross-sectional analysis aimed to describe lifestyle behaviours and CVD risk markers in young overweight and obese Australian women and explore associations between individual and combined lifestyle behaviours with CVD risk markers. Lifestyle behaviours assessed were diet quality, alcohol intake, physical activity, sitting time and smoking status, and were combined to generate a Healthy Lifestyle Score (HLS) (0-5). Objectively measured CVD risk markers were body mass index (BMI), %body fat, waist circumference, blood pressure, and plasma cholesterol and triglycerides. Analysis included 49 women aged 18-35 years, with BMI 25.0 to 34.9 kg/m². The mean ± SD Australian Recommended Food Score was 33.5 ± 9.3 points, alcohol 3.3 ± 2.4 standard drinks/day, physical activity 207 ± 225 min/week and sitting time 578 ± 213 min/day. All participants were non-smokers. The proportion of participants outside normal reference ranges was 83.7% for waist circumference (n = 41), blood pressure 0% (n = 0), total cholesterol 26.2% (n = 11), HDL cholesterol 38.6% (n = 17), LDL cholesterol 22.7% (n = 10), and triglycerides 4.2% (n = 2). Physical activity was inversely associated with body fat (β = -0.011%, p = 0.005), diastolic blood pressure (β = -0.010 mmHg, p = 0.031) and waist circumference (β = -0.013 cm, p = 0.029). Most participants (59.2%, n = 29) had a HLS ≤ 2. No significant associations were found between HLS and CVD risk markers. Insufficient physical activity was the primary lifestyle factor associated with increased CVD risk markers, which suggests interventions targeting physical activity in young women may potentially improve cardiovascular health.

    BACKGROUND The effect of legume-based hypocaloric diet on cardiovascular disease (CVD) risk factors in women is unclear. This study provides an opportunity to find effects of high-legume diet on CVD risk factors in women who consumed high legumes at baseline. METHODS This randomized controlled trial was undertaken in 34 premenopausal women with central obesity. After 2 weeks of a run-in period on an isocaloric diet, subjects were randomly assigned into two groups: (1) hypocaloric diet enriched with legumes (HDEL) (n = 17) (two servings per day) and (2) hypocaloric diet without legumes (HDWL) (n = 17) for 6 weeks. The following variables were assessed before intervention, 3, and 6 weeks after it: Waist to hip ratio (WHR), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-sensitive-C-reactive protein (hs-CRP), total antioxidant capacity (TAC), nitric oxides (NOx), and Malondialdehyde (MDA). RESULTS Both hypocaloric diets reduced hs-CRP in 3 weeks and returned it to basal values after 6 weeks (P = 0.004). HDWL significantly reduced WHR [P = 0.010 (3.2%)] and increased TC [P < 0.001 (6.3%)]. Despite the significant effect of HDEL on increasing TAC in 3 weeks [P = 0.050 (4%)], the level of TAC remained the same in 6 weeks. None of the diets had any significant effects on NOx and MDA. CONCLUSION The study indicated that beneficial effects of legumes on TC, LDL-C, and hs-CRP were achieved by three servings per week, and consuming more amounts of these products had no more advantages.

    Healthful dietary practices and a return to prepregnancy weight are of significant importance in the prevention of obesity for women. The Eating Stimulus Index (ESI) was used to determine the relationship between motivations to eat and diet quality and food intake in 115 overweight/obese, low-income women in early postpartum. In this cross-sectional design, participants completed the ESI and food frequency questionnaire. Diet quality was assessed using the Dietary Guidelines Adherence Index. Diet quality was related to greater fruit and vegetable availability, convenience eating resistance, and vegetable taste preference. Women with high fruit and vegetable availability consumed more vegetables, as compared to those with low availability. High convenience eating resistance was associated with lower discretionary energy intakes. High taste preference for vegetables was related to greater intakes of these foods. Hierarchical regression analysis indicated that convenience eating resistance was the strongest predictor of diet quality followed by vegetable taste preference, and fruit and vegetable availability. Convenience eating resistance was also the strongest predictor of discretionary energy intake. In conclusion, women who were less vulnerable to environmental eating cues, had greater fruit and vegetable availability, and preferred the taste of vegetables consumed a more healthful diet. Thus, the ESI may be a useful screening tool for the design of personalized weight loss messages in the treatment of obesity. PMID:20600414

    This study investigated the differences in eating disorder psychopathology, appearance satisfaction, and self-esteem between 194 overweight/obese college women with and without binge eating. Participants were categorized as binge eating (BE; n=56) or non-binge eating (NBE; n=138) based on reports of binge eating at least once per week on average for the past 28days and no episodes of vomiting or laxative use in the past 28days. The BE group had significantly greater levels of eating, weight, and shape concerns and lower levels of appearance satisfaction and self-esteem than the NBE group. For the BE group, binge eating frequency was negatively correlated with dietary restraint. Results are generally consistent with studies utilizing clinical and community samples. The findings extend such research by examining binge eating in a sample of overweight and obese college women and indicating that overall appearance satisfaction is lower among women with binge eating. Study findings also highlight potential issues to address in obesity and binge eating intervention efforts for college populations. Future research is needed to replicate these findings in additional samples of college women and men. PMID:25668799

    Objective Food reinforcement and delay discounting (DD) predict Body Mass Index (BMI), but there is no research studying whether these variables interact to improve prediction of BMI. Design and Methods BMI, the relative reinforcing value of high (PMAXHED) and low (PMAXLED) energy dense food, and DD for $10 and $100 future rewards (DD10, DD100) were measured in 199 adult females. Results PMAXHED (p = 0.017), DD10 (p = 0.003) and DD100 (p = 0.003) were independent predictors of BMI. The interaction of PMAXLED X DD10 (p = 0.033) and DD100 (p = 0.039), and PMAXHED X DD10 (p = 0.041) and DD100 (p = 0.045) increased the variance accounted for predicting BMI beyond the base model controlling for age, education, minority status, disinhibition and dietary restraint. Based on the regression model, BMI differed by about 2 BMI units for low versus high food reinforcement, by about 3 BMI units for low versus high DD, and by about 4 BMI units for those high in PMAXHED but low in DD versus high in PMAXHED and high in DD. Conclusions Reducing DD may help prevent obesity and improve treatment of obesity in those who are high in food reinforcement. PMID:24311480

    The incidence of breast cancer is increasing worldwide, and this seems to be related to an increase in lifestyle risk factors, including physical inactivity, and overweight/obesity. We previously reported that exercise induced a circulating angiostatic phenotype characterized by increased sFlt-1 and endostatin and decreased unbound-VEGF in men. However, there is no data on women. The present study determines the following: 1) whether moderate exercise increased sFlt-1 and endostatin and decreased unbound-VEGF in the circulation of adult female volunteers; 2) whether overweight/obese women have a higher plasma level of unbound-VEGF than lean women. 72 African American and Caucasian adult women volunteers aged from 18–44 were enrolled into the exercise study. All the participants walked on a treadmill for 30 minutes at a moderate intensity (55–59% heart rate reserve), and oxygen consumption (VO2) was quantified by utilizing a metabolic cart. We had the blood samples before and immediately after exercise from 63 participants. ELISA assays (R&D Systems) showed that plasma levels of sFlt-1 were 67.8±3.7 pg/ml immediately after exercise (30 minutes), significantly higher than basal levels, 54.5±3.3 pg/ml, before exercise (P < 0.01; n=63). There was no significant difference in the % increase of sFlt-1 levels after exercise between African American and Caucasian (P=0.533) or between lean and overweight/obese women (P=0.892). There was no significant difference in plasma levels of unbound VEGF (35.28±5.47 vs. 35.23±4.96 pg/ml; P=0.99) or endostatin (111.12±5.48 vs. 115.45±7.15 ng/ml; P=0.63) before and after exercise. Basal plasma levels of unbound-VEGF in overweight/obese women were 52.26±9.6 pg/ml, significantly higher than basal levels of unbound-VEGF in lean women, 27.34±4.99 pg/ml (P < 0.05). The results support our hypothesis that exercise-induced plasma levels of sFlt-1 could be an important clinical biomarker to explore the mechanisms of exercise

    2012-01-01

    Background An increase in the number of women with maternal obesity (Body Mass Index [BMI] ≥30 kg/m2) has had a huge impact on the delivery of maternity services. As part of a programme of feasibility work to design an antenatal lifestyle programme for women with a BMI ≥30 kg/m2, the current study explored health professionals’ experiences of caring for women with a BMI ≥30 kg/m2 and their views of the proposed lifestyle programme. Method Semi-structured interviews with 30 health professionals (including midwives, sonographers, anaesthetists and obstetricians) were conducted and analysed using thematic analysis. Recruitment occurred in two areas in the North West of England in early 2011. Results Three themes were evident. Firstly, obesity was seen as a conversation stopper; obesity can be a challenge to discuss. Secondly, obesity was seen as a maternity issue; obesity has a direct impact on maternity care and therefore intervention is needed. Finally, the long-term impact of maternal obesity intervention; lifestyle advice in pregnancy has the potential to break the cyclic obesity relationship. The health professionals believed that antenatal lifestyle advice can play a key role in addressing the public health issue of obesity as pregnancy is a time of increased motivation for women with a BMI ≥30 kg/m2. Conclusions Maternal obesity is a challenge and details of the training content required for health professionals to feel confident to approach the issue of maternal obesity with women are presented. Support for the antenatal lifestyle programme for women with a BMI ≥30 kg/m2 highlights the need for further exploration of the impact of interventions on health promotion. PMID:23253137

    Perturbations of energy balance induce compensatory processes that may alter expected weight loss. In obese patients, our aim was to investigate the relationships that occurred between fasting plasma concentrations of anorexigenic peptides and metabolic parameters, appetite, physical capacity, and weight loss in the 5 first days of a program associating exercise and caloric reduction. Thirteen obese women were monitored from day 1 to day 5 with 2 exercise sessions in day 2 and day 4. We measured, in a fasted state, changes in body weight, hunger ratings, and plasma concentrations of fatty acids, triglycerides, leptin, insulin, amylin, peptide YY, and insulin-resistance index. Physical performance was assessed by a 6-min walking test. The program resulted in significantly reduced body weight (0.75±0.4 kg; p=0.001), of plasma concentrations of triglycerides, insulin, amylin, peptide YY, and the insulin-resistance index, and also increased fatty acids (p<0.05). Hunger ratings were increased (p<0.05). Program-induced changes in fatty acids, leptin, and insulin concentrations were related to physical performance (r(2)=0.45, 0.59, and 0.52; p<0.05, respectively) and to weight loss (r(2)=0.65, 0.57, 0.55; p<0.05, respectively). Five days of diet and exercise induced weight loss, improved lipid profile, and decreased insulin resistance while hunger ratings increased. Subjects with higher physical capacity lost more weight, presented higher increases in fatty acids and lower changes of leptin and insulin concentrations suggesting a better metabolic flexibility. To reduce the compensatory responses that can occur with energy imbalances, our study supports to account for individual activity level before prescribing weight-loss program associating diet and exercise.

  4. Education is associated with lower levels of abdominal obesity in women with a non-agricultural occupation: an interaction study using China’s four provinces survey

    PubMed Central

    2013-01-01

    Background The prevalence of obesity is increasing rapidly in low- and middle-income countries (LMICs) as their populations become exposed to obesogenic environments. The transition from an agrarian to an industrial and service-based economy results in important lifestyle changes. Yet different socioeconomic groups may experience and respond to these changes differently. Investigating the socioeconomic distribution of obesity in LMICs is key to understanding the causes of obesity but the field is limited by the scarcity of data and a uni-dimensional approach to socioeconomic status (SES). This study splits socioeconomic status into two dimensions to investigate how educated women may have lower levels of obesity in a context where labour market opportunities have shifted away from agriculture to other forms of employment. Methods The Four Provinces Study in China 2008/09 is a household-based community survey of 4,314 people aged ≥60  years (2,465 women). It was used to investigate an interaction between education (none/any) and occupation (agricultural/non-agricultural) on high-risk central obesity defined as a waist circumference ≥80 cm. An interaction term between education and occupation was incorporated in a multivariate logistic regression model, and the estimates adjusted for age, parity, urban/rural residence and health behaviours (smoking, alcohol, meat and fruit & vegetable consumption). Complete case analyses were undertaken and results confirmed using multiple imputation to impute missing data. Results An interaction between occupation and education was present (P = 0.02). In the group with no education, the odds of central obesity in the sedentary occupation group were more than double those of the agricultural occupation group even after taking age group and parity into account (OR; 95%CI: 2.21; 1.52, 3.21), while in the group with any education there was no evidence of such a relationship (OR; 95%CI: 1.25; 0.92, 1.70).

    Obesity is typically associated with increased risk factors of cardiovascular diseases (CVDs). Therefore, a therapeutic approach that aims to control body weight and metabolic profile might be effective in preventing CVDs. We aimed to determine the effects of Nigella Sativa (NS) oil with a low-calorie diet on cardiometabolic risk factors in obese women. In this double-blind randomized controlled clinical trial, 90 obese women were recruited. Participants were females aged 25-50 years old with body mass index (BMI) between 30 and 35 kg m(-2). They were randomly assigned to receive a low-calorie diet with 3 g per day (1 g before each meal) NS oil or placebo for 8 weeks. Anthropometric indices, dietary intake and biochemical parameters were measured at the baseline and after the intervention. Eighty-four females completed the trial (intervention n = 43, placebo n = 41). Two groups were similar in the baseline characteristics. After the intervention, dietary intake was changed in both groups compared to the baseline, but the differences were not significant between the two groups. In the NS group, weight (-6.0 vs. -3.6%; p < 0.01) and waist circumference (-6.9 vs. -3.4%; p < 0.01) decreased significantly compared with the placebo group at the end of the trial. Comparison of biochemical parameters presented a significant decline in triglyceride (-14.0 vs. 1.4%; p = 0.02) and very low density lipoprotein (-14.0 vs. 7%; p < 0.01) levels in the NS group compared to the placebo group. NS oil concurrent with a low-calorie diet can reduce cardiometabolic risk factors in obese women. However, more clinical trials are needed to elucidate efficacy of NS as a complementary therapy in obese subjects. PMID:26029855

    The objective of this study was to investigate the impact of grandparental and parental education and parental educational trajectory on their adult offspring's overweight/obesity. We used register data from the Uppsala Birth Cohort Multigenerational Study, based on a representative cohort born in Sweden 1915-1929 (G1). Our sample included 5122 women and 11,204 men who were grandchildren of G1 (G3), their parents (G2), and grandparents. G3's overweight/obesity (BMI≥25 kg/m2) was based on pre-pregnancy weight/height for women before their first birth (average age=26 years), and measured weight/height at conscription for men (average age=18 years). G1's, G2's, and G3's highest educational attainment was obtained from routine registers and classified as low, intermediate, or high based on respective sample distributions. Parental (G2) educational trajectory was defined as change in education between their own and their highest educated parent (G1), classified into 5 categories: always advantaged (AA), upward trajectory (UT), stable-intermediate (SI), downward trajectory (DT), and always disadvantaged (AD). We used hierarchical gender-stratified logistic regression models adjusted for G3's age, education, year of BMI collection, lineage and G2's year of birth and income. Grandparental and parental education were negatively associated with men's odds of overweight/obesity and parental education affected women's overweight/obesity risk. Furthermore, men and women whose parents belonged to the UT, SI, DT, and AD groups had greater odds of overweight/obesity compared to men and women whose parents belonged to the AA group (adjusted for G3's age, year of BMI collection, lineage, and G2's year of birth). These associations were attenuated when further adjusting for parental income and G3's own education. Socioeconomic inequalities can have long-term consequences and impact the health of future generations. For overweight/obesity in concurrent young cohorts, this inequality

    Background Lifestyle interventions targeting obese pregnant women often result in modest reduction in gestational weight gain, pregnancy complications and related risk factors. Examining adherence to the intervention can, however, provide valuable information on the importance of the different factors targeted. Objective To evaluate improvements and relevance of different dietary factors targeted with respect to gestational weight gain in a 3-arm Randomised Controlled Trial (n=342) among obese pregnant women with BMI≥30 kg/m2. Methods Randomisation 1:1:1 to either hypocaloric Mediterranean type of diet and physical activity intervention (D+PA); physical activity intervention alone (PA); or control (C). Diet was assessed at baseline (weeks 11–14) and endpoint (weeks 36–37) using a validated food frequency questionnaire. Results During the intervention women in the D+PA group significantly lowered their intakes of added sugars and saturated fat and increased their protein intake by ~1% of total energy compared to controls. Of these dietary variables only intakes of added sugar appeared to be related to GWG, while no association was observed for saturated fat or protein. Further analyses revealed that foods that contributed to intake of added sugars, including sweets, snacks, cakes, and soft drinks were strongly associated with weight gain, with women consuming sweets ≥2/day having 5.4 kg (95% CI 2.1-8.7) greater weight gain than those with a low (<1wk) intake. The results for soft drinks were more conflicting, as women with high weight gain tended to favour artificially sweetened soft drinks. Conclusion In our sample of obese pregnant women, craving for sweets, snacks, and soft drinks strongly predicts GWG. Emphasis on reducing intakes of these foods may be more relevant for limiting gestational weight gain than encouraging strict compliance to more specific diets.
