This study characterized the prevalence of overweight and obesity and assessed their cardiometabolic comorbidities in the population aged 21-79 years living in the San Juan metropolitan area of Puerto Rico. We analyzed data from a household survey conducted in Puerto Rico between 2005 and 2007 that used a representative sample of 840 non-institutionalized adults living in the San Juan metropolitan area. Body mass index categories were classified as normal weight, overweight and obese. Poisson regression model with robust variance was used to estimate the prevalence ratio to assess the association of each cardiometabolic comorbidity (hypertension, dyslipidemia, diabetes, prediabetes, systemic inflammation, prothrombotic state, and coronary heart disease) with overweight and obesity. Age-standardized prevalence of overweight and obesity was 35.9 and 41.5%, respectively, figures higher than the combined prevalence for the U.S. adult population (68.8%) but similar to all mainland Hispanics (78.8%). Men were more likely to be overweight than women (40.4 vs. 33.4%), whereas more women than men were obese (43.7 vs. 37.6%). Prevalence of all cardiometabolic comorbidities was significantly (p < 0.05) higher among overweight and obese adults than those of normal weight after adjusting for age, sex, years of education, smoking status, alcohol consumption and physical activity. A considerable proportion of adults in this population are overweight or obese. In view of the wide-ranging effects that overweight and obesity have on health, preventive actions to avert the rise of excess body weight as well as the design of lifestyle interventions are largely needed in this population.

The purpose of this study was to investigate the prevalence of obesity, and the risk factors associated with it, in physically disabled adults living in the city centre of Malatya, Turkey. This research was designed as a cross-sectional study conducted on physically disabled people aged 20-65 years living in the city centre of Malatya. The prevalence of obesity in disabled people was within 95% CIs, the power was calculated as 80%, and the sample size of our population was calculated as 258 individuals. The prevalence of obesity was found to be 13.2%. The relationship between disability type and obesity status was found to be significant. The prevalence of obesity was 21.3% in visually impaired people, 17.9% in speech-impaired people, 17.8% in hearing-impaired people and 6.5% in orthopaedically disabled people. Educational interventions on nutrition and lifestyle can be effective considering the high prevalence of obesity in visually impaired people, the prevalence of weakness in orthopaedically disabled people and the risk related to the area in which body fat is localised even when body mass index is within the normal range. Training disabled people in sports appropriate to their disability type and building appropriate facilities for those sports might have a positive effect.

Childhood obesity is complex and requires a 'systems approach' that collectively engages across multiple community settings. Sustainable Childhood Obesity Prevention through Community Engagement (SCOPE) has implemented Live 5-2-1-0-a multi-sector, multi-component childhood obesity prevention initiative informed by systems thinking and participatory research via an innovative knowledge translation (KT) model (RE-FRAME). This paper describes the protocol for implementing and evaluating RE-FRAME in two 'existing' (>2 years of implementation) and two 'new' Live 5-2-1-0 communities to understand how to facilitate and sustain systems/community-level change. In this mixed-methods study, RE-FRAME was implemented via online resources, webinars, a backbone organization (SCOPE) coordinating the initiative, and a linking system supporting KT. Qualitative and quantitative data were collected using surveys and stakeholder interviews, analyzed using thematic analysis and descriptive statistics, respectively. Existing communities described the consistency of Live 5-2-1-0 and extensive local partnerships/champions as catalysts for synergistic community-wide action; new communities felt that the simplicity of the message combined with the transfer of experiential learning would inform their own strategies and policies/programs to broadly disseminate Live 5-2-1-0. RE-FRAME effectively guided the refinement of the initiative and provided a framework upon which evaluation results described how to implement a community-based systems approach to childhood obesity prevention.

Insulin resistance is common among children with overweight and obesity. However, knowledge about glucose fluctuations in these children is scarce. This study aims to evaluate glycaemic profiles in children with overweight and obesity in free-living conditions, and to examine the association between glycaemic profiles with insulin resistance and cardiovascular risk parameters. One hundred eleven children with overweight and obesity were included. 48-hour sensor glucose concentrations in free-living conditions, fasting plasma and post-glucose load concentrations, serum lipid and lipoprotein concentrations, homeostatic model assessment of insulin resistance (HOMA-IR), and blood pressure were evaluated. Hyperglycaemic glucose excursions (≥7.8 mmol/L) were observed in 25% (n = 28) of the children. The median sensor glucose concentration was 5.0 (2.7-7.3) mmol/L, and correlated with fasting plasma glucose concentrations (rs = 0.190, p = 0.046), serum insulin concentrations (rs = 0.218, p = 0.021), and HOMA-IR (rs = 0.230, p = 0.015). The hyperglycaemic area under the curve (AUC) correlated with waist circumference z-score (rs = 0.455, p = 0.025), triacylglycerol concentrations (rs = 0.425, p = 0.024), and HOMA-IR (rs = 0.616, p < 0.001). In conclusion, hyperglycaemic glucose excursions are frequently observed in children with overweight and obesity in free-living conditions. Children with insulin resistance had higher median sensor glucose concentrations and a larger hyperglycaemic sensor glucose AUC, which are both associated with specific parameters predicting cardiovascular disease risk.

Background Emerging evidence suggests that neighborhood characteristics can have direct and indirect effects on the weight status of the residents. Objectives To assess the relationship between general and central obesity and the neighborhood environment in two ethnic groups (Azeri Turks and Kurds) living in Urmia city, Northwestern Iran. Patients and Methods In this cross-sectional study, 723 participants (427 women and 296 men) aged 20 - 64 years from two ethnic groups (Azeri Turks, n = 445; Kurds, n = 278) were selected from 38 neighborhoods using a combination of cluster, random, and systematic sampling methods. Neighborhood characteristics were obtained by a validated 22-item neighborhood and a health observational checklist. General and central obesity were measured and evaluated using standard methods. Principal component analysis (PCA) was used to define the dominant neighborhood environment. The association of neighborhood characteristics with general and central obesity was analyzed by a logistic regression model. Results Three common neighborhood environments were identified: 1) modern-affluent, 2) central-high access and 3) marginal. These three factors explained 73.2% of the total variance. Overall, the participants living in a higher tertile of the central-high access neighborhoods had an increased chance of central obesity (OR = 1.63, 95% CI: 1.13 - 2.34). Azeri Turks living in the highest tertile of the modern-affluent neighborhoods had a significantly higher likelihood of having general obesity (OR = 2.49, 95% CI: 1.37 - 4.01). Adjustment for age, gender, marital status, socioeconomic status (SES), energy intake, and physical activity did not change the results. However, after adjustment for educational level, the association was not significant. Conclusions The findings point to a relationship between neighborhood characteristics and obesity only in the Azeri Turks. However, educational level was more important than neighborhood quality in

Obesity is a major contributor to the overall burden of disease (also reducing life expectancy) and associated with high medical costs due to obesity-related diseases. However, obesity prevention, while reducing obesity-related morbidity and mortality, may not result in overall healthcare cost savings because of additional costs in life-years gained. Sector-specific financial consequences of preventing obesity are less well documented, for pharmaceutical spending as well as for other healthcare segments. To estimate the effect of obesity prevention on annual and lifetime drug spending as well as other sector-specific expenditures, i.e. the hospital segment, long-term care segment and primary healthcare. The RIVM (Dutch National Institute for Public Health and the Environment) Chronic Disease Model and Dutch cost of illness data were used to simulate, using a Markov-type model approach, the lifetime expenditures in the pharmaceutical segment and three other healthcare segments for a hypothetical cohort of obese (body mass index [BMI] >or=30 kg/m2), non-smoking people with a starting age of 20 years. In order to assess the sector-specific consequences of obesity prevention, these costs were compared with the costs of two other similar cohorts, i.e. a 'healthy-living' cohort (non-smoking and a BMI >or=18.5 and <25 kg/m2) and a smoking cohort. To assert whether preventing obesity results in cost savings in any of the segments, net present values were estimated using different discount rates. Sensitivity analyses were conducted across key input values and using a broader definition of healthcare. Lifetime drug expenditures are higher for obese people than for 'healthy-living' people, despite shorter life expectancy for the obese. Obesity prevention results in savings on drugs for obesity-related diseases until the age of 74 years, which outweigh additional drug costs for diseases unrelated to obesity in life-years gained. Furthermore, obesity prevention will increase

Limited data are available describing donor adverse events (AEs) associated with filgrastim mobilized peripheral blood stem cell (PBSC) collections in unrelated volunteers. We report results in 2408 unrelated PBSC donors prospectively evaluated by the National Marrow Donor Program (NMDP) between 1999 and 2004. Female donors had higher rates of AEs, requiring central line placement more often (17% vs 4%, P < .001), experiencing more apheresis-related AEs (20% vs 7%, P < .001), more bone pain (odds ratio [OR] = 1.49), and higher rates of grades II-IV and III-IV CALGB AEs (OR = 2.22 and 2.32). Obese donors experienced more bone pain (obese vs normal, OR = 1.73) and heavy donors had higher rates of CALGB toxicities (> 95 kg vs < 70 kg, OR = 1.49). Six percent of donors experienced grade III-IV CALGB toxicities and 0.6% experienced toxicities that were considered serious and unexpected. Complete recovery is universal, however, and no late AEs attributable to donation have been identified. In conclusion, PBSC collection in unrelated donors is generally safe, but nearly all donors will experience bone pain, 1 in 4 will have significant headache, nausea, or citrate toxicity, and a small percentage will experience serious short-term adverse events. In addition, women and larger donors are at higher risk for donation-related AEs. PMID:19190248

The objectives of this study are to describe the mechanism of the program and to present initial donor outcome. This is a descriptive study evaluating the performance of a national program for nondirected kidney donation from living unrelated donors (LURDs) in the Philippines in its 3-year implementation. It explains the mechanism of the program and socioeconomic and clinical profiling of donors. Frequencies and percentages were used to measure donor demographic data, medical follow-up compliance rate, and employment predonation and postdonation. Diagnostic laboratory criteria were required to show donor clinical profiles. In 2002, the local Health Department issued an administrative order to create a National Transplant Ethics Committee (NTEC) to address issues of rampant organ sale and donor exploitation. It also set guidelines and intended to oversee transplantation from LURDs. Salient points to the program are as follows: (1) prohibition of sale; (2) accreditation of transplantation centers; (3) enrollment of waitlisted patients in both deceased donor and nondirected LURD program; (4) ethics committee evaluation of LURDs; (5) creation of a national kidney transplant wait list and live donor registry allowing centralized, nondirected kidney allocation; (6) 10% cap on allocation to foreigners; (7) creation of a kidney donor monitoring unit with free 10-year annual medical follow-up for feedback evaluation on donor outcome; and (8) allowance of gratitudinal gifts such as health and life insurance, reimbursement for lost income, educational plan, and job placement to LURDs run by a foundation. From 2004 to 2006, 695 potential donors enrolled; 97 were accepted and deemed medically fit to donate. The remaining 598 were rejected due to demand for outright sale (103), medical unsuitability (77), disapproval by the Ethics Committee (12), and retracted consent (406). Of the 97 qualified donors, 79 had donated, 9 were being evaluated, and 9 await allocation at the end of

The prevalence and incidence of both obesity and disability are projected to increase in the coming decades. The authors examined the relation between obesity and disability in older adults from 6 Latin American cities participating in the Health, Well-Being and Aging in Latin America and the Caribbean (SABE) Study (1999-2000). The sample included 6,166 participants aged 65 years or more. Data on sociodemographic factors, smoking status, medical conditions, body mass index (BMI; weight (kg)/height (m)(2)), and self-reported activities of daily living (ADL) were obtained. The prevalence of obesity (BMI > or = 30) ranged from 13.3% in Havana, Cuba, to 37.6% in Montevideo, Uruguay. Using a BMI of 18.5-<25 as the reference category and controlling for all covariates, the lowest odds ratio for ADL limitation was for a BMI of 25-<30 (odds ratio = 1.10, 95% confidence interval: 0.93, 1.30), and the highest odds ratio for ADL limitation was for a BMI of 35 or higher (odds ratio = 1.63, 95% confidence interval: 1.26, 2.11). The results indicated that obesity is an independent factor contributing to ADL disability in these populations and should be included in future planning to reduce the impact of disability on global health.

To document the changes in BMI and the prevalence of overweight and obesity in young women living in poverty in a semi-urban community in Mexico. Women who had previously participated in a longitudinal research study (1997-2000) were re-assessed in 2005. Anthropometric measurements were obtained using standard procedures, and socio-demographic questionnaires were administered. Total and annual rate of change in BMI and change in the prevalence of overweight and obesity (BMI > or = 25.0 and > or =30.0) were estimated. Mean age in 2005 was 30.0 +/- 5.7 years (n = 683) and time between recruitment and follow-up was 6.4 +/- 1.0 years. Mean change in BMI was +3.6 +/- 2.7 (range -8.2 to +14.6). In 2005, 500 (73.2%) women were overweight, up from 263 (38.5%) in the original assessment. The prevalence of obesity tripled over the follow-up period (from 9.8% to 30.3%). The mean annual rate of change in BMI was +0.6 (+/-0.4). After adjustment for age and parity at baseline, an annual rate of change of BMI above the sample median (>0.5) was associated with lower levels of formal education. The annual increase in the prevalence of overweight and obesity in this sample is double that which was reported at a national level in Mexico. An understanding of the determinants of this rapid increase among the women living in poverty in Mexico is urgently needed.

The greater use of living unrelated donors (LUDs) as kidney donors is a worldwide trend in the current era of organ shortage, and spouses are an important source of LUDs. This study was to compare the long-term outcomes of spousal donor grafts with other LUD grafts. Among 445 LUD grafts, 77 were spouses and 368 were other LUDs. The clinical characteristics and long-term survival rates for spousal transplants were compared with those for other LUD transplants, and risk factors affecting graft survival were assessed. Spousal donors had a significantly higher average number of human leukocyte antigen (HLA) mismatches (4.2 vs. 3.4, p < 0.001) and were older (41 vs. 33 years, p < 0.001) than LUDs. The 10-year survival rates for spousal donor grafts were 60.6%, similar to those for LUD grafts (58.5%, p = 0.61). The 10-year biopsy-proven acute rejection-free survival rates (85.5 vs. 89.6%, p = 0.45) and patient survival rates were also similar (84.3 vs. 79.6%, p = 0.35). The degree of HLA mismatching, the spousal donor type or donor age did not affect the graft survival. Renal transplants from spousal donors show similar long-term outcomes to those from better HLA-matched and younger LUDs. (c) 2009 S. Karger AG, Basel.

In the U.S., there has been a rise in overweight and obesity among persons living with HIV (PLWH). The aim of this study was to examine dietary intake and body mass index (BMI) in PLWH in Atlanta Georgia relative to the U.S. Dietary intake among PLWH was compared with recommended standards as well as estimated dietary intake for adults in the U.S. Over 31% of the study participants were overweight [BMI = 25-29.9 kg/m 2 ], and 33.1% obese [BMI ≥ 30 kg/m 2 ]. Results indicated significant dietary differences between participants in our sample and U.S. daily recommendations for adults as well as estimated intakes of the U.S. Both males and females consumed more percentage of energy from fat and less fiber as well as fruit and vegetables servings than what is recommended. Results suggest that overweight and obesity are an additional health burden to PLWH in our sample and that their daily dietary practices are not meeting the U.S. government-recommended nutritional standards.

Obesity stigma exists within many institutions and cultural settings. Most studies suggest that stigmatising experiences have a negative impact on individuals' health and social behaviours and outcomes. However, some studies indicate that obesity stigma can motivate individuals to lose weight. Limited research has examined weight-based stigma from the perspective of obese individuals, including their perceptions of, and responses to, the different types of weight-based stigma they face in their daily lives. This study advances knowledge about weight-based stigma by documenting how obese adults (mostly female) described the different types of obesity stigma that they faced, how they responded to this stigma, and how different types of stigma impact on health and social wellbeing. Semi-structured, qualitative interviews were conducted between April 2008 and March 2009 with a diverse sample of 141 obese Australian adults. Guided by Link and Phelan's (2006) categorisation of different types of discrimination, participants' experiences could be grouped into three distinct types of stigma: 1) Direct (e.g. being abused when using public transport); 2) Environmental (e.g. not being able to fit into seats on planes); and 3) Indirect (e.g. people staring at the contents of their supermarket trolley). Participants described that more subtle forms of stigma had the most impact on their health and social wellbeing. However, it was the interaction between direct, environmental and indirect stigma that created a barrier to participation in health-promoting activities. Participants rarely challenged stigma and often blamed themselves for stigmatising experiences. They also avoided situations where they perceived they would be stigmatised and constantly thought about how they could find a solution to their obesity. Copyright © 2011 Elsevier Ltd.

In children, abdominal obesity is a better predictor of the presence of cardiovascular risk factors than body mass index (BMI)-defined obesity. We aimed to evaluate the prevalence of abdominal obesity in the Greek pediatric population and to assess the impact of residence on the prevalence of both BMI-defined and abdominal obesity. In the context of the Childhood Obesity Surveillance Initiative of the World Health Organization (WHO) Regional Office for Europe, a national representative sample of 7.0-7.9 and 9.0-9.9-year-old children was evaluated (n = 2,531 and 2,700, respectively). Overweight and obesity according to BMI were estimated using both the WHO and International Obesity Task Force cut-off points. Abdominal obesity was defined as waist circumference/height ratio >0.5. The prevalence of abdominal obesity did not differ between 7-year-old boys and girls (25.2 and 25.3%, respectively; p = NS). Among 9-year-old children, abdominal obesity was more prevalent in boys than in girls (33.2 and 28.2%, respectively; p = 0.005). Among normal weight and overweight children, the prevalence of abdominal obesity was 1.6-6.8 and 21.8-49.1%, respectively. The prevalence of abdominal and BMI-defined obesity did not differ between children living in the mainland, in Crete and in other islands except in 7-year-old girls, where the prevalence of BMI-defined obesity was highest in those living in Crete, intermediate in those living in other islands and lowest in those living in the mainland. In 9-year-old boys and in 7- and 9-year-old girls, the prevalence of abdominal obesity was highest in children living in Athens and lowest in children living in Thessaloniki, whereas children living in other cities and in villages showed intermediate rates. The prevalence of abdominal obesity in 7-year-old boys and the prevalence of BMI-defined obesity did not differ between children living in cities and villages. The prevalence of pediatric abdominal obesity in Greece is among

The aim of this study was to investigate the association between oral health status and central obesity (CO) in Brazilian independent-living elderly. A cross-sectional study was carried out in a sample of 489 elderly, who were participants of the Study on Aging and Longevity, in Londrina, state of Parana. The number of natural teeth and use of prostheses were evaluated according to the World Health Organization criteria. The presence of CO was assessed using measures of waist circumference (WC) and waist-hip ratio (WHR). Information concerning sociodemographic profile and some systemic conditions was also collected. Data were analyzed using stepwise logistic regression, α=5%. According to WC and WHR measures, the prevalence of central obesity was 79.3% and 76.1%, respectively. CO according to WC was not associated with oral status. Considering the WHR measure, the following oral conditions were associated to CO: having fewer natural teeth (OR = 2.61; 95%CI = 1.17-5.80), being edentulous and wearing both upper and lower complete dentures (OR = 2.34; 95%CI = 1.11-4.93), and being edentulous wearing only the upper complete denture (OR = 2.64; 95%CI = 1.01-6.95). Traditional risk factors for CO such as gender, dyslipidemia, hypertension and diabetes were associated with both measures. A poor oral health due to extensive tooth loss, whether partial or complete, even if rehabilitated by removable prostheses, may be considered a good predictor of CO in Brazilian independent-living elderly.

This article presents the history of the debate on organ transplantation in Islam since the 1950s and the key ethical questions. It continues by presenting the opinions of the mainstream ulema such as Tantawi and Qaradawi. The article ends with a conclusion that there must be no compensation made to a non-related live organ donor, not even a symbolic gift of honor (ikramiyya). PMID:23908804

Living donor kidney transplantation: "beauty and the beast"!

PubMed

Danovitch, Gabriel M

2013-01-01

The report by Terasaki and colleagues in 1995 that the outcomes of spousal and biologically unrelated transplants were essentially the same as for 1-haplotype matched living related transplants changed the course of clinical transplantation. This article, entitled metaphorically "Beauty and the Beast", describes the dramatic change in the practice of living donor transplantation that followed. In the ensuing two decades, biologically unrelated living donor transplantation became commonplace in the developed world and reached its apotheosis in cross-country living donor paired exchange programs that have made transplantation accessible to many whose donors were deemed "incompatible". Such exchanges can indeed be thought of as a "thing of beauty". Sadly, the same observation was abused to exploit vulnerable donors, and the "beast" in the form of transplant tourism became a feature of transplantation in the developing world. The responsibility of the transplant community to protect the welfare of living donors and their recipients and the key role of trust in the evaluation of living donors is discussed.

Neighborhoods, Social and Cultural Correlates of Obesity Risk among Latinos living on the U.S.-Mexico border in Southern California.

We explored the relationship between obesity and neighborhood-related, social, and cultural variables and possible moderation by acculturation and cross-national practices. We obtained data from the 2009 San Diego Prevention Research Center's community survey, which used multistage sampling methods to recruit 397 adult respondents and conducted multilevel logistic analytic methods. Nearly half of the respondents were obese. Respondents had low acculturation scores and reported crossing the U.S.-Mexico border about three times per month, mostly to visit family and friends. Neighborhoods where respondents lived were predominantly Latino and had 27% home ownership. A significant cross-level interaction emerged: those who reported crossing the border and reported higher levels of collective efficacy were more likely to be obese than those who had not crossed. Study findings provide evidence of the complex relationship among obesity risk factors in a U.S.-Mexico border community that warrant further examination to prevent and control obesity.

Socioeconomic status has been associated with obesity in children and adolescents. This association may be dependent according with where adolescents lives. The aim of this study was to evaluate the association between different socioeconomic indicators such as parental education and occupation and socioeconomic status with abdominal obesity in adolescents from two observational studies: the Healthy Lifestyle in Europe by Nutrition in Adolescence cross-sectional study (HELENA-CSS) and the Brazilian Cardiovascular Adolescent Health (BRACAH) study. European (n = 3192, aged 12.5-17.5 years, with 53.1% girls from HELENA-CSS) and Brazilian (n = 991, aged 14-18 years, with 54.5% girls from BRACAH study) adolescents from two cross-sectional studies were included in this analysis. Complete data on waist circumference (WC), height, socioeconomic status indicators and several confounders were collected. Socioeconomic indicators were measured using a self-reported questionnaire in order to assess the family social status of the adolescents. Multilevel linear regression models were used to examine associations, and results were adjusted for potential confounders. Adjusted results showed inverse associations between mother's and father's education levels (p < 0.001) and father's occupation level (p < 0.001) with waist-to-height ratio (WHtR) and WC in HELENA-CSS girls. Similarly in European girls, socioeconomic indicators by socioeconomic status and maternal occupation level were associated with WHtR. In HELENA-CSS boys, the same significant association was found between WHtR and WC with maternal occupation level. Moreover, in European boys WHtR was also associated with parental education. In Brazilian adolescents, both indicators of abdominal obesity did not remain associated with the independents variables, after adjustment for potential confounders. Abdominal obesity was associated with socioeconomic indicators in higher-income countries, but this

Poor oral status, represented by partial/complete tooth loss, may lead to changes in food choice, which may ultimately lead to underweight, overweight, or obesity. The aim of this study is to evaluate whether poor oral status is associated with underweight or overweight/obesity, regardless of physical activity. This cross-sectional study is part of a major project, The Frailty in Brazilian Elderly Study, carried out in Campinas, Brazil (2008-2009). The sample was composed of 900 independent-living older adults. Complete data were available for 875 individuals including sociodemographic, self-reported amount of medications used and eating difficulty questionnaire, smoking habit, depressive symptoms, physical activity, oral examination, and anthropometric assessments according to the WHO criteria. Body mass index was used as an outcome. Multinomial logistic regression was adjusted for confounding variables. The mean age of the sample was 72.7 y (± 5.81) and the prevalence of edentulism was 47.7%. Edentate individuals not wearing dentures were more likely to be underweight [odds ratio (OR) = 3.94, 95% confidence interval (CI) 1.14-13.64] and overweight/obese (OR = 2.88, 95%CI 1.12-7.40). Males (OR = 0.56, 95%CI 0.36-0.85) and those not using medications (OR = 0.41 95%CI 0.24-0.70) were less likely to be overweight/obese. Individuals who smoke (OR = 2.62, 95%CI 1.26-5.44) were more likely to be underweight. Older individuals with family income between 3.1 and 5 minimum wage (OR = 1.69, 95%CI 1.00-2.87) were more likely to be overweight/obese. To our knowledge, this is one of the first studies associating poor oral health, represented by edentulism not rehabilitated with dentures, with unfavorable body mass, regardless of the two major confounders, physical activity and depression symptoms.

The current study aimed to determine the prevalence of obesity and overweight among Indian women living in Punjab, India and in Vienna, Austria. A series of 115 women ageing between 17 and 80 years (x = 38.7 yrs; +/- 14.5) was enrolled in the present study. 65 women lived in the district of Jalandhar in Punjab, 50 Punjabi women lived in as migrants in Vienna Austria. Data collection comprised an anthropometric analysis including stature height, body weight and the body mass index (BMI). For classification of the weight status the Indian BMI cutoffs defined by the WHO for Asian Indians were used. Data concerning dietary patterns and lifestyle parameters were collected by structured interviews using a standardized questionnaire. Among both subgroups overweight and obesity were highly prevalent. Underweight (18.5%) was significantly more prevalent in Punjab than in Vienna (6.0 %), while overweight and obesity were more frequently found among Punjabi women in Vienna (26.0%; 54.0%) than among Punjabi women in India (9.2%; 24.6 %). Analysing lifestyle and dietary patterns it turned out that energy dense meals were preferred and fat and sugar were used frequently among both subsamples. A statistically significant relationship between dietary habits and weight status could not be proved.

Sutin, Angelina R; Terracciano, Antonio

2013-01-01

Weight discrimination is prevalent in American society. Although associated consistently with psychological and economic outcomes, less is known about whether weight discrimination is associated with longitudinal changes in obesity. The objectives of this research are (1) to test whether weight discrimination is associated with risk of becoming obese (Body Mass Index≥30; BMI) by follow-up among those not obese at baseline, and (2) to test whether weight discrimination is associated with risk of remaining obese at follow-up among those already obese at baseline. Participants were drawn from the Health and Retirement Study, a nationally representative longitudinal survey of community-dwelling US residents. A total of 6,157 participants (58.6% female) completed the discrimination measure and had weight and height available from the 2006 and 2010 assessments. Participants who experienced weight discrimination were approximately 2.5 times more likely to become obese by follow-up (OR = 2.54, 95% CI = 1.58-4.08) and participants who were obese at baseline were three times more likely to remain obese at follow up (OR = 3.20, 95% CI = 2.06-4.97) than those who had not experienced such discrimination. These effects held when controlling for demographic factors (age, sex, ethnicity, education) and when baseline BMI was included as a covariate. These effects were also specific to weight discrimination; other forms of discrimination (e.g., sex, race) were unrelated to risk of obesity at follow-up. The present research demonstrates that, in addition to poorer mental health outcomes, weight discrimination has implications for obesity. Rather than motivating individuals to lose weight, weight discrimination increases risk for obesity.

The proportion of obese adolescents in Southern Appalachia is among the highest in the nation. Through funding from the National Institute on Minority Health and Health Disparities – National Institutes of Health, the Team Up for Healthy Living project was a cluster-randomized trial targeting obesity prevention in adolescents through a cross-peer intervention. The specific aims of the project were to: 1) develop a peer-based health education program focusing on establishing positive peer norms towards healthy eating and physical activity (PA) among high school students, 2) test program efficacy, and 3) explore mechanisms underlying the program. The study was guided by the Theory of Planned Behavior, which presupposes that human behavior is primarily driven by attitude, subjective norms, perceived behavioral control, and social support. To deliver the intervention, undergraduate students from the disciplines of public health, nutrition, and kinesiology were hired as peer facilitators. Ten area high schools were invited to participate, were matched on demographics and then randomized to intervention or control. The primary outcomes of the study included body mass status, dietary behaviors, PA, and sedentary behaviors which were assessed at baseline and at three and twelve months post baseline. Intervention schools received Team Up for Healthy Living curriculum, which consists of eight 40-minute sessions. The curriculum focused on improving nutrition awareness, PA, leadership and communication. Control schools received their regularly scheduled Lifetime Wellness curriculum. The long-term goal of the study was to establish an effective academia–community partnership program to address adolescent obesity disparity in Southern Appalachia. PMID:25937506

The purpose of this article was to compile all existing data regarding the prevalence of obesity in Austria in all age groups, and to perform additional analyses. Prevalence of obesity in the adult Austrian population varies between 8.3 and 19.9% in men, and 9.0 and 19.8% in women with increasing trends over time. Prevalence of obesity in children and adolescents in Austria varies between 3.1 and 9.0% in boys and between 2.2 and 7.3% in girls. Factors associated with obesity include higher age, lower educational level, profession, migration background, living in eastern parts of Austria, lack of social support, and psycho-social pressure. In women, socio-economic parameters are stronger associated with obesity compared to men. Obesity is associated with hypertension, diabetes mellitus, osteoarthritis, and low back pain, and deteriorated quality of live, in both sexes, and in men additionally with a history of heart attack, and in women additionally with anxiety/depression.

To estimate the potential to reduce childhood obesity through targeted interventions of overweight households. Cross-sectional nationally representative samples of the Scottish population. Households in Scotland during 2008 and 2009. A total of 1651 households with parents and children aged 2-15 years. The WHO cut-off points for adult body mass index (BMI): overweight (25 to <30 kg/m2) and obese (≥30 kg/m2). Overweight and obesity in childhood respectively defined as a BMI 85th to <95th percentile and ≥95th percentile based on 1990 reference centiles. Thirty-two percent (600/1849) of children and 75% (966/1290) of adults were overweight or obese. Seventy-five percent (1606/2128) of all children lived with a parent who was overweight or obese. Among obese children, 58% (185/318) lived with an obese parent. The population attributable risk percentage of child obesity associated with parental obesity was 32.5%. Targeting obese households would require substantial falls in adult weight and need to reach 38% of all children; it might achieve a reduction in the prevalence of childhood obesity of 14% in these households (from 26% to 12%). Targeting parents with BMI ≥ 40 might reduce the overall prevalence of child obesity by 9%. Such an intervention would require large weight loss, consistent with approaches used for morbidly obese adults; it would involve 4% of all children and lead to a reduction in the prevalence of obesity in these households from 57% to 16%. Family-based interventions for obesity would be most efficiently targeted at obese children whose parents are morbidly obese.

Living organ donation: an ethical evolution or evolution of ethics?

PubMed

Ghahramani, N

2010-01-01

The disparity between available and needed organs is rapidly increasing, and the number of patients dying while still on the waiting list is growing exponentially. As a partial solution to this disparity, living unrelated transplantation is being performed more frequently, and some have proposed providing financial incentives to donors. The aim of this discussion is to illustrate that with an ever-increasing number of living unrelated transplantations, society and the transplant community should adopt a more active role in developing specific strategies to scrutinize the process. The current paper will also examine the viewpoint that medical ethics is not separable from the prevailing needs of society and involves a constant balancing of often opposing goods. Issues surrounding living unrelated donor transplantation illustrate ethics as a dynamically evolving field, which is often influenced by necessity and which evolves with progression of science and society. As part of this evolution, it is the collective responsibility of society and the transplant community to devise safeguards to guarantee adherence to basic principles of ethics and to avoid "situational ethics."

Whether the combination of obesity and low muscle strength (dynapenic-obesity) would cause greater impairment of the activities of daily living (ADL)/instrumental activities of daily living (IADL) than obesity alone and low muscle strength alone (dynapenia) remains unclear. The aim of this study was to reveal the possible independent and additive effects of dynapenia and obesity on ADL/IADL disability in an older Chinese population. A cross-sectional study, including 616 community-dwelling older adults, was conducted in China from 2010 to 2012. Based on the World Health Organization Asian Criteria of Obesity and handgrip strength tertiles, 4 independent groups were identified as follows: nondynapenia/nonobesity, dynapenia alone, obesity alone, and dynapenic-obesity. The Katz Index of Independence in ADL was used to assess ADL disability, whereas 6 IADL items of the Older Americans Resources and Services (OARS) multidimensional functional assessment questionnaire were used to assess IADL disability. The prevalence of ADL and IADL disability was 21.1% and 28.9% in the dynapenic-obesity group, 15.5% and 22.6% in the dynapenia alone group, 13.1% and 19.6% in the obesity alone group, and 11.9% and 12.9% in the nondynapenia/nonobesity group, respectively. After adjusting for the covariates, in comparison with the dynapenic-obesity group, the adjusted odds ratios (95% confidence interval) for ADL disability were 0.36 (0.13-0.73) in the nondynapenia/nonobesity group, 0.51 (0.20-0.78) in the dynapenia-alone group, and 0.40 (0.11-0.61) in the obesity-alone group. The corresponding data for IADL disability were 0.55 (0.20-0.93), 0.82 (0.39-0.98), and 0.61 (0.30-0.91), respectively. Dynapenia, obesity, and dynapenic-obesity were associated with an increased risk of ADL/IADL disability. Dynapenic-obesity was associated with a greater risk of ADL/IADL disability in comparison with dynapenia or obesity alone. Copyright © 2014 American Medical Directors Association, Inc

Obesity is a chronic metabolic disorder affecting half a billion people worldwide. Major difficulties in managing obesity are the cessation of continued weight loss in patients after an initial period of responsiveness and rebound to pretreatment weight. It is conceivable that chronic weight gain unrelated to physiological needs induces an allostatic regulatory state that defends a supranormal adipose mass despite its maladaptive consequences. To challenge this hypothesis, we generated a reversible genetic mouse model of early-onset hyperphagia and severe obesity by selectively blocking the expression of the proopiomelanocortin gene (Pomc) in hypothalamic neurons. Eutopic reactivation of central POMC transmission at different stages of overweight progression normalized or greatly reduced food intake in these obesity-programmed mice. Hypothalamic Pomc rescue also attenuated comorbidities such as hyperglycemia, hyperinsulinemia, and hepatic steatosis and normalized locomotor activity. However, effectiveness of treatment to normalize body weight and adiposity declined progressively as the level of obesity at the time of Pomc induction increased. Thus, our study using a novel reversible monogenic obesity model reveals the critical importance of early intervention for the prevention of subsequent allostatic overload that auto-perpetuates obesity.

Strong challenges exist about living kidney transplantation practices worldwide. One of these concerns is based on the observation that in many places women constitute the majority of living kidney donors but the minority of recipients. We studied this issue in Iran by using national data for kidney transplantation. Data of the Iranian national registry for kidney transplantation which comprises data of all renal transplantations performed in the country during a 22 yr period were included in the study. Data of 16,672 living donors (living related [LR]=16%, living unrelated [LUR]=86%) were analyzed. Males received 62.2% of all kidney transplants. From 16,672 living donors, 20% and 80% were women and men, respectively. Recipients were more likely to receive kidney allograft from their own gender groups (p<0.05). In living related donations, mothers, brothers and sons were significantly more often donors than their counterparts of opposite gender. In contrast with previous reports from other countries, this study of Iranian national data revealed that in Iran, most related and unrelated living kidney donors are male and the percentage of recipients who are female exceeds the percentage of donors who are female. Considering previous reports from other countries, our findings suggest that Iran is the only country in which females are more likely to be recipients of a kidney allograft than donors. The reason for the predominance of male kidney donors in Iran is probably multifactorial and associated with economical, social and cultural issues. The financial incentives paid to living unrelated donors may be an attraction for males to donate a kidney although, even in living related donations, males constitute the majority of donors. © 2009 John Wiley & Sons A/S.

Entry into romantic partnership is associated with obesity.

BMI is highly correlated between spouses; however, less is understood about the underlying mechanism(s) by which the development of obesity in one individual increases the risk of obesity in his/her spouse. The objective of this study is to investigate whether romantic partnership and duration of cohabitation are related to incident obesity and obesity-promoting behaviors. We used two data sets from the National Longitudinal Study of Adolescent Health: (i) 6,949 US adolescents (wave II, 1996) followed into adulthood (wave III, 2001-2002) and (ii) 1,293 dating, cohabiting, and married romantic couples from wave III, including measured anthropometry and self-report behavior data. In the longitudinal cohort, we used sex-stratified logistic regression models to examine the risk of incident obesity by longitudinal romantic relationship status and duration of time spent living with a romantic partner. In the Couples Sample, we used multinomial logistic regression to predict concordance in outcomes: obesity, moderate-to-vigorous physical activity, and screen time by romantic partnership and duration of time living with a romantic partner. Individuals who transitioned from single/dating to cohabiting or married were more likely to become obese than those who were dating at both waves. Partner concordance for negative, obesity-related behaviors was strongest for married couples and couples who lived together > or =2 years. The shared household environment may increase the likelihood of becoming obese, influence partner concordance, and may be an important target for obesity intervention.

Background Several studies have identified multiple obesity-associated loci mainly in European populations. However, their contribution to obesity in other ethnicities such as Mexicans is largely unknown. The aim of this study was to examine 26 obesity-associated single-nucleotide polymorphisms (SNP) in a sample of Mexican mestizos. Methods 9 SNPs in biological candidate genes showing replications (PPARG, ADRB3, ADRB2, LEPR, GNB3, UCP3, ADIPOQ, UCP2, and NR3C1), and 17 SNPs in or near genes associated with obesity in first, second and third wave GWAS (INSIG2, FTO, MC4R, TMEM18, FAIM2/BCDIN3, BDNF, SH2B1, GNPDA2, NEGR1, KCTD15, SEC16B/RASAL2, NPC1, SFRF10/ETV5, MAF, PRL, MTCH2, and PTER) were genotyped in 1,156 unrelated Mexican-Mestizos including 683 cases (441 obese class I/II and 242 obese class III) and 473 normal-weight controls. In a second stage we selected 12 of the SNPs showing nominal associations with obesity, to seek associations with quantitative obesity-related traits in 3 cohorts including 1,218 Mexican Mestizo children, 945 Mexican Mestizo adults, and 543 Indigenous Mexican adults. Results After adjusting for age, sex and admixture, significant associations with obesity were found for 6 genes in the case-control study (ADIPOQ, FTO, TMEM18, INSIG2, FAIM2/BCDIN3 and BDNF). In addition, SH2B1 was associated only with class I/II obesity and MC4R only with class III obesity. SNPs located at or near FAIM2/BCDIN3, TMEM18, INSIG2, GNPDA2 and SEC16B/RASAL2 were significantly associated with BMI and/or WC in the combined analysis of Mexican-mestizo children and adults, and FTO locus was significantly associated with increased BMI in Indigenous Mexican populations. Conclusions Our findings replicate the association of 8 obesity-related SNPs with obesity risk in Mexican adults, and confirm the role of some of these SNPs in BMI in Mexican adults and children.

to understand the lived experiences and views of being referred to an antenatal dietetic service from the perspective of pregnant women with obesity. a qualitative, interpretive approach using one-to-one in-depth interviews to explore the lived experience of pregnant women with obesity following referral to an antenatal dietetics service. Thematic content analysis was carried out by two researchers independently to develop data-driven themes. one NHS Trust maternity and dietetic services, North East England, UK. fifteen pregnant women with a booking body mass index ≥30kg/m 2 attending an obesity-specific antenatal dietetic service. All women were White, parity between 0 and 2, and BMI range 30-51kg/m 2 . four themes were identified. (1) Women's overall experience of the service: experiences were predominately positive with only two negative cases identified. (2) Process of referral: women placed importance on informative and in-person communication about the service, with health professionals, at the point of referral. (3) Delivery of the service: dietitians were considered to be the experts and women wanted more frequent contact. (4) Content of the service: tailored advice enabled behaviour change, and women desired increased physical activity support and weight monitoring. women reported an overall positive experience and thought that dietitians were the expert health professionals to support them. Women in this study felt that tailoring advice specific to their personal circumstances helped them implement changes, and had a strong interest in the nutritional benefits for fetal development. Women considered weight monitoring to be a positive element of the service; however, further research is required given the limited and conflicting evidence-base. it is important to incorporate women's experiences in the development and delivery of antenatal weight management services to facilitate person-centred care.

Narrative messages have the potential to convey causal attribution information about complex social issues. This study examined attributions about obesity, an issue characterized by interrelated biological, behavioral, and environmental causes. Participants were randomly assigned to read one of three narratives emphasizing societal causes and solutions for obesity or an unrelated story that served as the control condition. The three narratives varied in the extent to which the character in the story acknowledged personal responsibility (high, moderate, and none) for controlling her weight. Stories that featured no acknowledgment and moderate acknowledgment of personal responsibility, while emphasizing environmental causes and solutions, were successful at increasing societal cause attributions about obesity and, among conservatives, increasing support for obesity-related policies relative to the control group. The extent to which respondents were able to make connections between individual and environmental causes of obesity (complex integration) mediated the relationship between the moderate acknowledgment condition and societal cause attributions. We conclude with a discussion of the implications of this work for narrative persuasion theory and health communication campaigns.

Introduction. Obesity is defined by the World Health Organization (WHO) as a disease characterized by the excessive accumulation of body fat. Obesity is considered a public health problem, leading to serious social, psychological and physical problems. However, the appropriate cut-off point of body mass index (BMI) based on body fat percentage (BF%) for classifying an individual as obese in middle-aged adults living in Rio de Janeiro remains unclear. Materials and methods. This was a prospective cross-sectional study comprising of 856 adults (413 men and 443 women) living in Rio de Janeiro, Brazil ranging from 30-59 years of age. The data were collected over a two year period (2010-2011), and all participants were underwent anthropometric evaluation. The gold standard was the percentage of body fat estimated by bioelectrical impedance analysis. The optimal sensitivity and specificity were attained by adjusting BMI cut-off values to predict obesity based on the WHO criteria: BF% >25% in men and >35% in women, according to the receiver operating characteristic curve (ROC) analysis adjusted for age and for the whole group. Results. The BMI cut-offs for predicting BF% were 29.9 kg/m2 in men and 24.9 kg/m2 in women. Conclusions The BMI that corresponded to a BF% previously defining obesity was similar to that of other Western populations for men but not for women. Furthermore, gender and age specific cut-off values are recommended in this population. Significance for public health World Health Organization (WHO) defines obesity as a disease characterized by the excessive accumulation of body fat. Obesity is considered a public health problem, leading to serious social, psychological and physical problems. The WHO suggested cut-off point for obesity is a body mass index (BMI) of 30 kg/m2, which is associated with morbidity and mortality. An important issue in the debate over measuring obesity concerns the use of BMI to define obesity across different populations. However

Impact of social pressure on stereotypes about obese people.

PubMed

Harper, Jessica; Carels, Robert A

2014-01-01

This study was designed to test the effects of different types of influence on the expression of stereotypes towards people who are obese. It was hypothesized that public social pressure would more significantly impact the expression of stereotypes towards obese people than other types of influence. One-hundred fifty-eight undergraduate students were randomly assigned to one of three conditions or a control condition. Participants completed measures of stereotypes towards obese people prior to and after receiving manipulated feedback depicting purported stereotypes possessed by others (anonymously or publically) or scientific information about the base rates of these stereotypical traits in the obese population (i.e., trait prevalence). Participants also completed a measure of weight bias unrelated to the manipulated feedback. Explicit beliefs were influenced more when people perceived that others' views were inconsistent with their own in a public setting than an anonymous setting or when they received trait prevalence feedback. However, levels of weight bias on a separate measure were unchanged. Strong, public manipulations of social feedback have great potential to impact, at least, the short-term expression of stereotypes towards obese people.

Economic causes and consequences of obesity.

Obesity is not only a health but also an economic phenomenon. This chapter (a) examines underlying economic causes, such as technological advancements, behind the obesity epidemic; (b) describes economic consequences of obesity, including increasing obesity-related medical expenditures; and (c) discusses the role of government in combating the obesity epidemic. Because of the high costs of obesity, and the fact that the majority of these costs are financed by taxpayers, there is a clear motivation for government to try to reduce these costs. However, because obesity may result from poor information and addictive behavior and/or as a result of living in an increasingly obesogenic environment, interventions will need to be multifaceted to ensure the best chance of success.

Personal Conflict Impairs Performance on an Unrelated Self-Control Task: Lingering Costs of Uncertainty and Conflict.

People have the ability to make important choices in their lives, but deliberating about these choices can have costs. The present study was designed to test the hypothesis that writing about conflicted personal goals and values (conflict condition) would impair self-control on an unrelated subsequent task as compared to writing about clear personal goals and values (clarity condition). Personal conflict activates the behavioral inhibition system (BIS; Hirsh, Mar, & Peterson, 2012), which may make it harder for participants to successfully execute self-control. In this large ( N =337), pre-registered study participants in the conflict condition performed worse on anagrams than participants in the clarity condition, and the effect of condition on anagram performance was mediated by a subjective uncertainty measure of BIS activation. This suggests that BIS activation leads to poor self-control. Moreover, given that conflict is inherent in the exercise of self-control, results point to BIS activation as a mechanism for why initial acts of self-control impair self-control on subsequent, unrelated tasks.

Unrelated Helpers in a Primitively Eusocial Wasp: Is Helping Tailored Towards Direct Fitness?

2010-01-01

The paper wasp Polistes dominulus is unique among the social insects in that nearly one-third of co-foundresses are completely unrelated to the dominant individual whose offspring they help to rear and yet reproductive skew is high. These unrelated subordinates stand to gain direct fitness through nest inheritance, raising the question of whether their behaviour is adaptively tailored towards maximizing inheritance prospects. Unusually, in this species, a wealth of theory and empirical data allows us to predict how unrelated subordinates should behave. Based on these predictions, here we compare helping in subordinates that are unrelated or related to the dominant wasp across an extensive range of field-based behavioural contexts. We find no differences in foraging effort, defense behaviour, aggression or inheritance rank between unrelated helpers and their related counterparts. Our study provides no evidence, across a number of behavioural scenarios, that the behaviour of unrelated subordinates is adaptively modified to promote direct fitness interests. PMID:20700463

The perception of brightness of unrelated self-luminous colored stimuli of the same luminance has been investigated. The Helmholtz-Kohlrausch (H-K) effect, i.e., an increase in brightness perception due to an increase in saturation, is clearly observed. This brightness perception is compared with the calculated brightness according to six existing vision models, color appearance models, and models based on the concept of equivalent luminance. Although these models included the H-K effect and half of them were developed to work with unrelated colors, none of the models seemed to be able to fully predict the perceived brightness. A tentative solution to increase the prediction accuracy of the color appearance model CAM97u, developed by Hunt, is presented.

The purpose of this study is to assess the prevalence of overweight/obesity, abdominal obesity and obesity-related risk factors in southern China. A cross-sectional survey of 15,364 participants aged 15 years and older was conducted from November 2013 to August 2014 in Jiangxi Province, China, using questionnaire forms and physical measurements. The physical measurements included body height, weight, waist circumference (WC), body fat percentage (BFP) and visceral adipose index (VAI). Multivariate logistic regression analysis was performed to evaluate the risk factors for overweight/obesity and abdominal obesity. The prevalence of overweight was 25.8% (25.9% in males and 25.7% in females), while that of obesity was 7.9% (8.4% in males and 7.6% in females). The prevalence of abdominal obesity was 10.2% (8.6% in males and 11.3% in females). The prevalence of overweight/obesity was 37.1% in urban residents and 30.2% in rural residents, and this difference was significant (P < 0.001). Urban residents had a significantly higher prevalence of abdominal obesity than rural residents (11.6% vs 8.7%, P < 0.001). Among the participants with an underweight/normal body mass index (BMI), 1.3% still had abdominal obesity, 16.1% had a high BFP and 1.0% had a high VAI. Moreover, among obese participants, 9.7% had a low /normal WC, 0.8% had a normal BFP and 15.9% had a normal VAI. Meanwhile, the partial correlation analysis indicated that the correlation coefficients between VAI and BMI, VAI and WC, and BMI and WC were 0.700, 0.666, and 0.721, respectively. A multivariate logistic regression analysis indicated that being female and having a high BFP and a high VAI were significantly associated with an increased risk of overweight/obesity and abdominal obesity. In addition, living in an urban area and older age correlated with overweight/obesity. This study revealed that obesity and abdominal obesity, which differed by gender and age, are epidemic in southern China. Moreover, there

The foreign textile fibers recovered from one item of evidence from each of 20 unrelated crimes in three categories (bank robbery, kidnapping, and homicide) were cross-compared. The items of evidence were scraped to remove the trace evidence and a sample of the collected fibers was examined using a standard scheme of analysis. The fibers were examined with light microscopy (including polarized light microscopy), fluorescence microscopy, and microspectrophotometry. The fibers were divided into natural and manufactured groups and then categorized by color and generic (polymer) class. Cross-comparing all 2083 fibers resulted in 2,168,403 comparisons, after removing duplicate (same fiber) comparisons. Colorless and denim fibers were excluded from this study. No two fibers were found to exhibit the same microscopic characteristics and analytical properties. Therefore, it is rare to find two unrelated items that have foreign fibers that are analytically indistinguishable. These results corroborate other population studies conducted in Europe and target fiber studies conducted both in the US and in Europe.

Obstructive sleep apnea (OSA) and periodic limb movements during sleep (PLMs) are sleep-related disorders with a high prevalence in type 2 diabetes. Commonly OSA is considered as a consequence of obesity, but several previous studies have shown the presence of OSA in non-obese diabetic patients. A previous study showed higher PLMs prevalence in patients with type 2 diabetes, compared to age-matched controls. We speculated that both OSA and PLMs may reflect the presence of diabetic autonomic neuropathy. To test this hypothesis, we compared a group of 112 non-obese patients with type 2 diabetes with 66 age-, sex-, and body mass index- matched nondiabetic patients. Both groups have been investigated through a set of tests including the Epworth Sleepiness Scale, polysomnography, and the Orthostatic Grading Scale (OGS), a questionnaire to assess the degree of autonomic dysfunction. Diabetic patients with OSA and PLMs scored higher on the OGS than controls. Our results confirm that both OSA and PLMs are related to dysautonomy and may be unrelated to obesity in type 2 diabetes patients.

Trends in unrelated-donor kidney transplantation in the developing world.

Barsoum, Rashad S

2008-11-01

Living unrelated donors (LUDs) constitute an incremental source of kidneys for transplantation at a global level. Excellent outcomes are reported, superior to those of deceased-donor transplantation and comparable to related donor transplantation. LUD include six categories: spouses, distant relatives, paired-exchange, living-deceased exchange, and non-directed and directed donors. Although a financial reward may be involved in any of these categories, it is in the declared selling of organs that ethical concerns have intensified. There are three patterns of paid LUDs in the developing world: organized, erratic and commercial. The only model of organized LUDs is in Iran, where a central agency assigns and compensates the donors. Erratic LUD transplantation has been experienced, and subsequently banned, in the development of transplant programmes in most developing countries. However, the tightness and enforcement of the official ban are geographically different, providing variable room for uncontrolled trafficking. Commercial transplantation has, thus, become phenomenal in a few countries, gradually evolving into an organized business that follows market dynamics, including advertisement, brokerage, commissions, auctions and tourism. While most international organizations and activist groups condemn commercial transplantation, it is often perceived, in certain cultures and under particular socioeconomic standards, as a human right that meets the demands of all stakeholders, and should be organized rather than declined just for the purpose of meeting the values of a third party.

To evaluate the consequences of plasma from individuals with obesity on parameters associated with immunosenescence in unrelated healthy peripheral blood mononuclear cells (PBMC). Freshly isolated PBMC were incubated in media supplemented with 10% of plasma from individuals with obesity or control subjects for the first 4 hours of 24 to 120 hours of culture. Plasma from individuals with obesity modulated the phenotype of healthy PBMC, leading to a higher rate of apoptosis, lower amounts of phospho-γH2AX and -p53, and mitochondrial dysfunction. After 120 hours, there was a higher secretion of inflammatory cytokines IL-1β and IL-8. CD8 + T lymphocytes presented decreased expression of CD28, which is associated with the immunosenescent phenotype. CD14 + macrophages showed increased expression of CD80 and CD206, suggesting a modulation in the activation of macrophages. These results demonstrate that chronic systemic inflammation observed in obesity induces dysfunctional features in PBMC that are consistent with premature immunosenescence. © 2017 The Obesity Society.

HLA matching in unrelated donor bone marrow transplantation.

PubMed

Charron, D J

1996-11-01

The availability of an HLA-matched sibling donor in only 30% to 35% of patients requiring allogeneic bone marrow transplantation (BMT) has led to the proposal of unrelated donors as an alternative source of bone marrow. The greater HLA incompatibility, which, although present, was undetected until recently in many unrelated donor BMT cases, has resulted in a higher rate of posttransplant complications and impaired acturial survival when compared with HLA-matched sibling BMT. Molecular HLA typing enables us to evaluate the impact of incompatibility at each locus in the outcome of unrelated donor BMT. The overall retrospective data would recommend that HLA-A, -B and -C allelic molecular matching should be implemented in addition to HLA-DR allelic matching. Further retrospective analysis is needed in order to assess which incompatibility or combinations are better tolerated than others. Only the definitive knowledge at the sequence level of the donor and the recipient HLA allelic diversity involved in controlling the allogeneic immune response will allow us to understand the precise biologic rationale of the graft-versus-host disease. Knowledge and control of the HLA incompatibilities should allow us to offset the detrimental effects of histoincompatibility while developing strategies to take advantage of the beneficial graft-versus-leukemia effect. Also the role of minor histocompatibility antigens remains largely unknown and will require careful evaluation before minor antigens can be used as a selection criterion in BMT. Carefully designed prospective studies will enable us to test the impact of each HLA locus. HLA typing and BMT represent a successful example of productive cooperation between basic and clinical sciences that should be pursued for the improvement of the clinical outcome of unrelated donor BMT.

Objectives. To investigate the association between walkability and obesity, we studied adults residing in Baltimore City, Maryland, in neighborhoods of varying racial and socioeconomic composition. Methods. We conducted a cross-sectional study of 3493 participants from the study Healthy Aging in Neighborhoods of Diversity across the Life Span. We used the Pedestrian Environment Data Scan to measure neighborhood walkability in 34 neighborhoods of diverse racial and socioeconomic composition in which the study participants lived. Confirmatory factor analysis was used to determine walkability scores. Multilevel modeling was used to determine prevalence ratios for the association between walkability and obesity. Results. Among individuals living in predominately White and high-socioeconomic status (SES) neighborhoods, residing in highly walkable neighborhoods was associated with a lower prevalence of obesity when compared with individuals living in poorly walkable neighborhoods, after adjusting for individual-level demographic variables (prevalence ratio–[PR] = 0.58; P = <.001 vs PR = 0.80; P = .004). Prevalence ratios were similar after controlling for the perception of crime, physical activity, and main mode of transportation. The association between walkability and obesity for individuals living in low-SES neighborhoods was not significant after accounting for main mode of transportation (PR = 0.85; P = .060). Conclusions. Future research is needed to determine how differences in associations by neighborhood characteristics may contribute to racial disparities in obesity. PMID:21164099

Quantitating the frequency of T cell cross-reactivity to unrelated peptides is essential to understanding T cell responses in infectious and autoimmune diseases. Here we used 15 mouse or human CD8+ T cell clones (11 antiviral, 4 anti-self) in conjunction with a large library of defined synthetic peptides to examine nearly 30,000 TCR-peptide MHC class I interactions for cross-reactions. We identified a single cross-reaction consisting of an anti-self TCR recognizing a poxvirus peptide at relatively low sensitivity. We failed to identify any cross-reactions between the synthetic peptides in the panel and polyclonal CD8+ T cells raised to viral or alloantigens. These findings provide the best estimate to date of the frequency of T cell cross-reactivity to unrelated peptides ( approximately 1/30,000), explaining why cross-reactions between unrelated pathogens are infrequently encountered and providing a critical parameter for understanding the scope of self-tolerance.

Four children with vincristine toxicity unrelated to dose are described. Fever, haematological toxicity, and abdominal distension occurred 2-7 days after vincristine was given. Convulsions occurred 6-8 days after vincristine in all 4. Inappropriate secretion of antidiuretic hormone was thought to have occurred in 3 patients. 2 patients died during the acute toxicity phase. Necropsy findings did not show neuronal changes which could be directly ascribed to vincristine. PMID:179476

Safety of living donors is critical to the success of blood, tissue and organ transplantation. Structured and robust vigilance and surveillance systems exist as part of some national entities, but historically no global systems are in place to ensure conformity, harmonisation and the recognition of rare adverse events (AEs). The World Health Assembly has recently resolved to require AE/reaction (AE/R) reporting both nationally and globally. The World Marrow Donor Association (WMDA) is an international organisation promoting the safety of unrelated donors and progenitor cell products for use in haematopoietic progenitor cell (HPC) transplantation. To address this issue, we established a system for collecting, collating, analysing, distributing and reacting to serious adverse events and reactions (SAE/R) in unrelated HPC donors. The WMDA successfully instituted this reporting system with 203 SAE/R reported in 2011. The committee generated two rapid reports, reacting to specific SAE/R, resulting in practice changing policies. The system has a robust governance structure, formal feedback to the WMDA membership and transparent information flows to other agencies, specialist physicians and transplant programs and the general public.

The prevalence of obesity in the United States has increased significantly and is a particular concern for minority men. Studies focused at the community and national levels have reported that geography can play a substantial role in contributing to obesity, but little is known about how regional influences contribute to obesity among men. The objective of this study is to examine the association between geographic region and obesity among men in the United States and to determine if there are racial/ethnic differences in obesity within these geographic regions. Data from men, aged 18 years and older, from the National Health Interview Survey were combined for the years 2000 to 2010. Obesity was defined as body mass index (BMI) ≥30 kg/m(2) Logistic regression models were specified to calculate the odds ratio (OR) and 95% confidence interval (CI) for the association between geographic region and obesity and for race and obesity within geographic regions. Compared to men living in the Northeast, men living in the Midwest had significantly greater odds of being obese (OR = 1.09, 95% CI [1.02, 1.17]), and men living in the West had lower odds of being obese (OR = 0.82, 95% CI [0.76, 0.89]). Racial/ethnic differences were also observed within geographic region. Black men have greater odds of obesity than White men in the South, West, and Midwest. In the South and West, Hispanic men also have greater odds of obesity than White men. In all regions, Asian men have lower odds of obesity than White men. © The Author(s) 2015.

Obesity and the lifestyle characteristic of Indian society lead young people to conditions of potential cardiovascular risk. The purpose of this study was to assess the prevalence of overweight/obesity and central obesity and its associated factors in a sample of Indian university students. In a cross-sectional survey assessed anthropometric measurements and a self-administered questionnaire among a sample of randomly selected university students. The sample included 800 university students from non health (mainly sciences) courses Gitam University in India. The students were 541 (67.6%) males and 259 (32.4%) females in the age range of 17-20 years (M age 18.2 years, SD=1.0). 37.5% were overweight or obese, 26.8% overweight (≥23-27.4 BMI) and 10.7% obese (≥27.5 kg/m(2)), 11.7% underweight (<18.5 kg/m(2)) and 16.4% central obesity (WC ≥90 cm for men and ≥80 cm for women). In multivariate analysis among men lack of non-organised religious activity (odds ratio=OR 0.85, confidence interval=CI 0.77-0.95), lower dietary risk knowledge (OR=0.64, CI=0.41-0.99), tobacco use (OR=2.23, CI=1.14-4.38), and suffering from depression (OR=1.59, CI=1.00-2.47) were associated with overweight/obesity, and younger age (OR=0.32, CI=0.12-0.90), lives away from parents or guardians (OR=1.79, CI=1.04-3.07), healthy dietary practices (OR=1.95, CI=1.02-3.72) and 9 or more hours sleep duration (OR=0.28, CI=0.09-0.96) were associated with central obesity. In bivariate analysis among women, lack of social support, lower dietary risk knowledge, tobacco use, and 9 or more hours sleep duration were associated with overweight/obesity and lives away from parents or guardians and abstinence from alcohol associated with central obesity. The study found a high prevalence of overweight/obesity and central obesity. Several gender specific health risk practices were identified including lack of dietary risk knowledge, shorter sleep duration, living away from parents or guardians, tobacco use and

Obesity is prevalent in rural communities in Canada, however little is known about the social determinants of health and obesity in rural populations. Socioeconomic status has been found to be inversely associated with the risk of obesity in developed countries. This study investigated the relationship between income adequacy, education and obesity in a rural setting. The study used data from 5391 adults aged 18-69 who participated in the Saskatchewan Rural Health Study in 2010. Participants completed a survey that included questions about location of residence, body weight, height, and socio-demographic and behavioral factors. Obesity was defined as body mass index being ≥ 30 kg/m(2). Logistic regression using generalized estimating equation was conducted to assess the associations of income adequacy and education level with the prevalence of obesity taking covariates into consideration. Approximately a third of the participants were obese and the prevalence of obesity was similar for men and women. The prevalence of obesity was significantly higher for rural residents not living on farm compared with those living on farm (p < 0.05). After adjustment for potential confounders, the risk of obesity was increased for those with ≤ 12 years of education compared with those with > 12 years of education (aOR: 1.18; 95% CI: 1.05-1.34). Low income adequacy was significantly associated with an increased risk of obesity but only among those not living on farm (aOR: 1.80; 95% CI: 1.16-2.79). Home location was associated with obesity prevalence in rural Saskatchewan and modified the influence of income adequacy, but not the influence of education, on obesity. Adults not living on farm had an increased risk of obesity and showed a significant impact of income adequacy on obesity.

This study recorded maternal perceptions of preschool children's weight in Chinese mothers living in Australia and China. A survey was undertaken of 1951 mothers living in Chengdu and Wuhan, China and 89 Chinese mothers living in Perth, Australia. All participants were mothers with children aged 2-4 years. The children's weight and height were measured and their weight status were classified using the International Obesity Task Force 2012 revised international child body mass index cut-offs. The prevalence of overweight or obese in children was 16.7% in China and 8% in Australia. The overall percentages of correct maternal perception of the child's weight were 35% in underweight children, 69.2% in normal weight children but only 10.8% in overweight/ obese children. Among the overweight/obese children, only 14% in Australia and 10.8% in China were classified as overweight/obese by their mothers. Within the group of underweight children, normal weight mothers (p=0.004) and mothers with older age children (p=0.015) were more likely to correctly classify children's weight status. A higher percentage of overweight/obese mothers (p=0.002) and mothers who over-estimated her own weight status (p<0.001) have correct perception of the weight status of their overweight/obese children, compared to their counterparts. There was a high prevalence of incorrect maternal perception of preschool children's weight status in Chinese mothers, especially those with overweight/obese children. To address the obesity epidemic in children, future health promotion programs should put improved efforts to educate parents about obesity and its health consequences in order to reduce misperceptions.

Differences in obesity by sex, age group, race and Hispanic origin among US adults have been reported, but differences by urbanization level have been less studied. To provide estimates of obesity by demographic characteristics and urbanization level and to examine trends in obesity prevalence by urbanization level. Serial cross-sectional analysis of measured height and weight among adults aged 20 years or older in the 2001-2016 National Health and Nutrition Examination Survey, a nationally representative survey of the civilian, noninstitutionalized US population. Sex, age group, race and Hispanic origin, education level, smoking status, and urbanization level as assessed by metropolitan statistical areas (MSAs; large: ≥1 million population). Prevalence of obesity (body mass index [BMI] ≥30) and severe obesity (BMI ≥40) by subgroups in 2013-2016 and trends by urbanization level between 2001-2004 and 2013-2016. Complete data on weight, height, and urbanization level were available for 10 792 adults (mean age, 48 years; 51% female [weighted]). During 2013-2016, 38.9% (95% CI, 37.0% to 40.7%) of US adults had obesity and 7.6% (95% CI, 6.8% to 8.6%) had severe obesity. Men living in medium or small MSAs had a higher age-adjusted prevalence of obesity compared with men living in large MSAs (42.4% vs 31.8%, respectively; adjusted difference, 9.8 percentage points [95% CI, 5.1 to 14.5 percentage points]); however, the age-adjusted prevalence among men living in non-MSAs was not significantly different compared with men living in large MSAs (38.9% vs 31.8%, respectively; adjusted difference, 4.8 percentage points [95% CI, -2.9 to 12.6 percentage points]). The age-adjusted prevalence of obesity was higher among women living in medium or small MSAs compared with women living in large MSAs (42.5% vs 38.1%, respectively; adjusted difference, 4.3 percentage points [95% CI, 0.2 to 8.5 percentage points]) and among women living in non-MSAs compared with women living in

Factors contributing to adolescent obesity.

Obesity in children is a significant public health concern. The prevalence of overweight and obesity in Jordanian children, and adolescents has increased in the last decade. The consequences of obesity to health in childhood and adulthood have both medical, and economic cost to individuals and society. This paper reviews the factors that contribute to adolescent obesity and emphasizes behavioral and environmental factors. An individual's behaviors such as increased consumption of high caloric foods, increased sedentary activity while decreasing physical activity has been identified as key issues in the development of obesity. Additionally, the current environment in homes, schools, and neighborhoods tend to discourage a healthy lifestyle. A comprehensive approach that involves the whole community is the best strategy for preventing adolescent obesity. Nurses are in a unique position to provide leadership in developing programs for healthier lifestyle choices for adolescents' and adoption of these goals into their daily lives.

Identifying faces is a process central for social interaction and a relevant factor in eyewitness theory. False recognition is a critical mistake during an eyewitness's identification scenario because it can lead to a wrongful conviction. Previous studies have described neural areas related to false facial recognition using the standard Deese/Roediger-McDermott (DRM) paradigm, triggering related false recognition. Nonetheless, misidentification of faces without trying to elicit false memories (unrelated false recognition) in a police lineup could involve different cognitive processes, and distinct neural areas. To delve into the neural circuitry of unrelated false recognition, we evaluated the memory and response confidence of participants while watching faces photographs in an fMRI task. Functional activations of unrelated false recognition were identified by contrasting the activation on this condition vs. the activations related to recognition (hits) and correct rejections. The results identified the right precentral and cingulate gyri as areas with distinctive activations during false recognition events suggesting a conflict resulting in a dysfunction during memory retrieval. High confidence suggested that about 50% of misidentifications may be related to an unconscious process. These findings add to our understanding of the construction of facial memories and its biological basis, and the fallibility of the eyewitness testimony.

To compare the contribution of "trial-sibling" and "unrelated" qualitative studies in complex intervention reviews. Researchers are using qualitative "trial-sibling" studies undertaken alongside trials to provide explanations to understand complex interventions. In the absence of qualitative "trial-sibling" studies, it is not known if qualitative studies "unrelated" to trials are helpful. Trials, "trial-sibling," and "unrelated" qualitative studies looking at three health system interventions were identified. We looked for similarities and differences between the two types of qualitative studies, such as participants, intervention delivery, context, study quality and reporting, and contribution to understanding trial results. Reporting was generally poor in both qualitative study types. We detected no substantial differences in participant characteristics. Interventions in qualitative "trial-sibling" studies were delivered using standardized protocols, whereas interventions in "unrelated" qualitative studies were delivered in routine care. Qualitative "trial-sibling" studies alone provided insufficient data to develop meaningful transferrable explanations beyond the trial context, and their limited focus on immediate implementation did not address all phenomena of interest. Together, "trial-sibling" and "unrelated" qualitative studies provided larger, richer data sets across contexts to better understand the phenomena of interest. Findings support inclusion of "trial-sibling" and "unrelated" qualitative studies to explore complexity in complex intervention reviews. Copyright © 2016 Elsevier Inc. All rights reserved.

Objective To test how genomic loci identified in genome-wide association studies influence the development of obesity. Design A 38-year prospective longitudinal study of a representative birth cohort. Setting The Dunedin Multidisciplinary Health and Development Study, Dunedin, New Zealand. Participants One thousand thirty-seven male and female study members. Main Exposures We assessed genetic risk with a multilocus genetic risk score. The genetic risk score was composed of single-nucleotide polymorphisms identified in genome-wide association studies of obesity-related phenotypes. We assessed family history from parent body mass index data collected when study members were 11 years of age. Main Outcome Measures Body mass index growth curves, developmental phenotypes of obesity, and adult obesity outcomes were defined from anthropometric assessments at birth and at 12 subsequent in-person interviews through 38 years of age. Results Individuals with higher genetic risk scores were more likely to be chronically obese in adulthood. Genetic risk first manifested as rapid growth during early childhood. Genetic risk was unrelated to birth weight. After birth, children at higher genetic risk gained weight more rapidly and reached adiposity rebound earlier and at a higher body mass index. In turn, these developmental phenotypes predicted adult obesity, mediating about half the genetic effect on adult obesity risk. Genetic associations with growth and obesity risk were independent of family history, indicating that the genetic risk score could provide novel information to clinicians. Conclusions Genetic variation linked with obesity risk operates, in part, through accelerating growth in the early childhood years after birth. Etiological research and prevention strategies should target early childhood to address the obesity epidemic. PMID:22665028

Context The relationship between obesity and osteoporosis has been widely studied, and epidemiological evidence shows that obesity is correlated with increased bone mass. Previous analyses, however, did not control for the mechanical loading effects of total body weight on bone mass and may have generated a confounded or even biased relationship between obesity and osteoporosis. Objective To re-evaluate the relationship between obesity and osteoporosis by accounting for the mechanical loading effects of total body weight on bone mass. Methods We measured whole body fat mass, lean mass, percentage fat mass (PFM), body mass index (BMI), and bone mass in two large samples of different ethnicity: 1,988 unrelated Chinese subjects and 4,489 Caucasian subjects from 512 pedigrees. We first evaluated the Pearson correlations among different phenotypes. We then dissected the phenotypic correlations into genetic and environmental components, with bone mass unadjusted, or adjusted, for body weight. This allowed us to compare the results with and without controlling for mechanical loading effects of body weight on bone mass. Results In both Chinese and Caucasians, when the mechanical loading effect of body weight on bone mass was adjusted for, the phenotypic correlation (including its genetic and environmental components) between fat mass (or PFM) and bone mass was negative. Further multivariate analyses in subjects stratified by body weight confirmed the inverse relationship between bone mass and fat mass, after mechanical loading effects due to total body weight was controlled. Conclusions Increasing fat mass may not have a beneficial effect on bone mass. PMID:17299077

To investigate the mediation effects of physical activity (PA) on the relationship between the perceived neighborhood aesthetic environment and overweight/obesity in free-living South Africans. A cross-sectional study of 671 adults aged ≥ 35 years was analyzed. PA was assessed using the validated International Physical Activity Questionnaire. Perceived neighborhood aesthetics was assessed using the Neighborhood Environment Walkability Scale Questionnaire. Of 671 participants, 76.0% were women, 34.1% aged 45-54 years, and 69.2% were overweight or obese. In adjusted logistic regression models, overweight/obesity was significantly associated with neighborhood aesthetics [odds ratio (OR) = 0.68; 95% confidence interval (CI), 0.50-0.93] and PA (OR = 0.65; 95% CI, 0.65-0.90). In expanded multivariable models, overweight/obesity was associated with age 45-55 years (OR = 1.59; 95% CI, 1.05-2.40), female gender (OR = 6.24; 95% CI, 3.95-9.86), tertiary education (OR = 4.05; 95% CI, 1.19-13.86), and urban residence (OR = 2.46; 95% CI, 1.66-3.65). Aesthetics was positively associated with PA; both aesthetics and PA were negatively associated with overweight and obesity. There was no evidence to support a significant mediating effect of PA on the relationship between aesthetics and overweight/obesity. Future studies should consider objective assessment of aesthetics and PA. In addition, future studies should consider using longitudinal design to evaluate food-related environments, which are related to overweight or obesity.

Background Renal transplantation is the ideal method for management of end-stage renal disease. The use of living donors for renal transplantation was critical for early development in the field and preceded the use of cadaveric donors. Most donors are related genetically to the recipients, like a parent, a child, or a sibling of the recipient, but there are an increasing percentage of cases where donors are genetically unrelated like spouses, friends, or altruistic individuals. Donor shortages constitute the major barrier for kidney transplantation, and much effort has been made to increase the supply of living donors. The impact of donor source on the outcome of renal transplantation is not adequately studied in our country. Objectives The aim of the study was to evaluate the impact of donor source on the outcome of live donor kidney transplantation. Patients and Methods From March 1976 to December 2013, the number of patients that underwent living renal transplantation sharing at least one HLA haplotype with their donors was 2,485. We divided these patients into two groups: (1) 2,075 kidney transplant recipients (1,554 or 74.9% male and 521 or 25.1% female) for whom the donors were living related, (2) 410 kidney transplant recipients (297 or 72.4% male and 113 or 27.6% female) for whom the donors were living unrelated. All patients received immunosuppressive therapy, consisting of a calcineurin inhibitor, mycophenolate mofetil, or azathioprine and prednisolone. We compared acute rejection and complication rates, as well as long-term graft and patient survival of both groups. Demographic characteristics were compared using the chi-square test. Graft survival and patient survival were calculated using the Kaplan-Meier method. Results The percentages of patients with acute vascular rejection were significantly higher in the unrelated group, while percentages of patients with no rejection were significantly higher in the related group, but there were no significant

Although surveillance data are limited in the US Affiliated Pacific, Alaska, and Hawaii, existing data suggest that the prevalence of childhood obesity is similar to or in excess of other minority groups in the contiguous US. Strategies for addressing the childhood obesity epidemic in the region support the use of community-based, environmentally targeted interventions. The Children's Healthy Living Program is a partnership formed across institutions in the US Affiliated Pacific, Alaska, and Hawaii to design a community randomized environmental intervention trial and a prevalence survey to address childhood obesity in the region through affecting the food and physical activity environment. The Children's Healthy Living Program community randomized trial is an environmental intervention trial in four matched-pair communities in American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, and Hawaii and two matched-pair communities in Alaska. A cross-sectional sample of children (goal n = 180) in each of the intervention trial communities is being assessed for outcomes at baseline and at 24 months (18 months post-intervention). In addition to the collection of the participant-based measures of anthropometry, diet, physical activity, sleep and acanthosis nigricans, community assessments are also being conducted in intervention trial communities. The Freely Associated States of Micronesia (Federated States of Micronesia, and Republics of Marshall Islands and Palau) is only conducting elements of the Children's Healthy Living Program sampling framework and similar measurements to provide prevalence data. In addition, anthropometry information will be collected for two additional communities in each of the 5 intervention jurisdictions to be included in the prevalence survey. The effectiveness of the environmental intervention trial is being assessed based on the RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework. The Children

2016-06-01

The number of older adults living in the USA, 65 years of age and older, has been steadily increasing. Data from the National Health and Nutrition Examination Survey (NHANES), 2007-2010, indicate that more than one-third of older adults, 65 years of age and older, were obese. With the increased rate of obesity in older adults, the purpose of this paper is to present research on different methods to prevent or manage obesity in older adults, namely dietary interventions, physical activity interventions, and a combination of dietary and physical activity interventions. In addition, research on community assistance programs in the prevention of obesity with aging will be discussed. Finally, data on federal programs for older adults will also be presented.

Quantitating the frequency of T cell cross-reactivity to unrelated peptides is essential to understanding T cell responses in infectious and autoimmune diseases. Here we used 15 mouse or human CD8+ T cell clones (11 antiviral, 4 anti-self) in conjunction with a large library of defined synthetic peptides to examine nearly 30,000 TCR-peptide MHC class I interactions for cross-reactions. We identified a single cross-reaction consisting of an anti-self TCR recognizing a poxvirus peptide at relatively low sensitivity. We failed to identify any cross-reactions between the synthetic peptides in the panel and polyclonal CD8+ T cells raised to viral or alloantigens. These findings provide the best estimate to date of the frequency of T cell cross-reactivity to unrelated peptides (∼1/30,000), explaining why cross-reactions between unrelated pathogens are infrequently encountered and providing a critical parameter for understanding the scope of self-tolerance.

Unrelated business income tax: an update.

PubMed

Fama, A J

1984-02-01

To meet spiraling costs, tax-exempt hospitals increasingly are operating businesses unrelated to direct patient care. Knowing which activities may be open to challenge by the Internal Revenue Service (IRS) is essential to avoid the unrelated business income (UBI) tax. Three criteria must be met for an activity to be taxable as UBI: It must constitute a trade or business; It must be regularly carried on; and It must be unrelated to the organization's exempt purpose. The Internal Revenue Code and IRS rulings clearly exclude the following areas from UBI taxation: Activities performed by unpaid volunteers (e.g., hospital auxiliaries' fund-raising dinners and bazaars and the operation of thrift stores); Operations conducted for the convenience of the organization's members, students, patients, or employees (e.g., gift shops, cafeterias, coffee shops, parking lots, lounges, vending machines, pharmaceutical sales to inpatients and emergency room outpatients, and research activities for students' benefit; The sale of merchandise that has been received by gift (e.g., flea markets, baked goods sales, book sales, and rummage sales); Investment income such as dividends, interest, annuities, royalties, certain rents, and capital gains from the sale of investment assets; Gifts or contributions made directly to the facility; and Bingo games that are conducted commercially. Areas which may be subject to UBI taxation, or in which there have been controversial or contradictory court rulings, include: Pharmaceutical sales to the public or private physicians' patients; and Laboratory services provided to private physicians for treating their patients. IRS private letter rulings, though not precedential, have excluded from UBI taxation the x-ray income from a hospital's branch facility and rental income from property leased for use as a clinic or medical office building that is substantially related to the hospital's exempt functions. Private letter rulings have subjected to UBI

The prevalence of obesity among Mexicans is alarming in both the child and adult populations. The objective of this study was to determine the levels of overweight, obesity and abdominal obesity in pre-school (PS), elementary (ES), and middle high (MHS) public school children from Tijuana. From February to April of 2011, a bietapic random sample was selected by cluster method of 30 PS, 30 ES, and 30 MHS children. And a sample of 30 groups for each level was chosen. Twenty elementary teachers and eight graduate students were trained at one central location on how to take anthropometric measurements using a portable scale, a stadiometer, and a measuring tape to determine weight, height, and waist circumference. Body Mass Index values were computed and compared to age/gender BMI percentiles according to WHO criteria. Waist circumference for-age at the 90th percentile from NHANES III (Mexican-American) was used to define abdominal obesity. The sample was composed of 646 PS children, 961 ES children, and 1,095 MHS children. Their ages ranged from 4- 16 years. Results showed an overall prevalence of overweight and obesity in younger than 5y preschool children (> 2 SD) of 23.1%, in ≥ 5 y PS (> 1 SD) of 33.8%, in ES children of 46.3%, and in MHS children of 41.9%. Abdominal obesity in PS children was 18%, in ES children was 16.7%, and in MHS children was 15.2%. These results warrant immediate and comprehensive actions to prevent a critical public health problem in Mexico. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA.

People living with HIV are surviving longer on successful antiretroviral therapy and obesity rates are increasing. We sought to determine the prevalence of being overweight or obese in a regional population of people living with HIV and to explore the demographic and clinical characteristics associated with obesity or being overweight. Data on patients attending three Northeast England clinics were collected including body mass index and demographics. The prevalence of being overweight (body mass index ≥ 25 kg/m 2 ) or obese (body mass index ≥ 30 kg/m 2 ) was determined and compared with regional population data. Associations between being overweight or obese and demographic and other data were further explored using logistic regression models. In 560 patients studied (median age 45 years, 26% Black-African and 69% male), 65% were overweight/obese and 26% obese, which is similar to the local population. However, 83% and 48% of Black-African women were overweight/obese or obese, respectively, with 11% being morbidly obese (body mass index > 40 kg/m 2 ). In the multivariate analyses, the only factors significantly associated with obesity were Black-African race (adjusted odds ratio 2.78, 95% confidence interval 1.60-4.85) and type 2 diabetes (adjusted odds ratio 4.23, 95% confidence interval 1.81-9.91). Levels of obesity and overweight in people living with HIV are now comparable to the levels in the local population of Northeast England; however, the prevalence is significantly higher in Black-African women. Given the additional risk factors for cardiovascular disease inherent in people living with HIV, better strategies to prevent, identify and manage obesity in this population are needed.

Developing obesity prevention interventions among minority ethnic children in schools and places of worship: The DEAL (DiEt and Active Living) study

2009-01-01

Background Childhood obesity is a major public health concern with serious implications for the sustainability of healthcare systems. Studies in the US and UK have shown that ethnicity is consistently associated with childhood obesity, with Black African origin girls in particular being more vulnerable to overweight and obesity than their White peers. Little is known, however, about what promotes or hinders engagement with prevention programmes among ethnic minority children. Methods/Design This paper describes the background and design of an exploratory study conducted in London, UK. The aim of the study was to assess the feasibility, efficacy and cultural acceptability of child- and family-based interventions to reduce risk factors for childhood and adolescent obesity among ethnic minorities. It investigated the use of a population approach (in schools) and a targeted approach (in places of worship). We used a mixture of focus group discussions, in-depth interviews and structured questionnaires to explore what children, parents, grandparents, teachers and religious leaders think hinder and promote engagement with healthy eating and active living choices. We assessed the cultural appropriateness of validated measures of physical activity, dietary behaviour and self efficacy, and of potential elements of interventions informed by the data collected. We are also currently assessing the potential for wider community support (local councils, community networks, faith forums etc) of the intervention. Discussion Analysis of the data is ongoing but the emergent findings suggest that while the school setting may be better for the main implementation of healthy lifestyle interventions, places of worship provide valuable opportunities for family and culturally specific support for implementation. Tackling the rise in childhood and adolescent obesity is a policy priority, as reflected in a range of government initiatives. The study will enhance such policy by developing the

Homeostatic theory of obesity

PubMed Central

2015-01-01

Health is regulated by homeostasis, a property of all living things. Homeostasis maintains equilibrium at set-points using feedback loops for optimum functioning of the organism. Imbalances in homeostasis causing overweight and obesity are evident in more than 1 billion people. In a new theory, homeostatic obesity imbalance is attributed to a hypothesized ‘Circle of Discontent’, a system of feedback loops linking weight gain, body dissatisfaction, negative affect and over-consumption. The Circle of Discontent theory is consistent with an extensive evidence base. A four-armed strategy to halt the obesity epidemic consists of (1) putting a stop to victim-blaming, stigma and discrimination; (2) devalorizing the thin-ideal; (3) reducing consumption of energy-dense, low-nutrient foods and drinks; and (4) improving access to plant-based diets. If fully implemented, interventions designed to restore homeostasis have the potential to halt the obesity epidemic. PMID:28070357

Religiosity has been associated with greater body weight. Less is known about South Asian religions and associations with weight. Cross-sectional analysis of the MASALA study (n = 906). We examined associations between religious affiliation and overweight/obesity after controlling for age, sex, years lived in the USA, marital status, education, insurance status, health status, and smoking. We determined whether traditional cultural beliefs, physical activity, and dietary pattern mediated this association. The mean BMI was 26 kg/m 2 . Religious affiliation was associated with overweight/obesity for Hindus (OR 2.12; 95 % CI: 1.16, 3.89), Sikhs (OR 4.23; 95 % CI: 1.72, 10.38), and Muslims (OR 2.79; 95 % CI: 1.14, 6.80) compared with no religious affiliation. Traditional cultural beliefs (7 %), dietary pattern (1 %), and physical activity (1 %) mediated 9 % of the relationship. Interventions designed to promote healthy lifestyle changes to reduce the burden of overweight/obesity among South Asians need to be culturally and religiously tailored.

Emergence of an Israel faith-based community organization facilitating live donor kidney transplantation.

The 2014 Consensus Conference on Best Practices in Living Kidney Donations recognized live donor kidney transplantation as the best treatment for late-stage kidney disease, yielding superior graft and patient survival, improved quality of life, fewer requirements for dialysis and increased cost-effectiveness compared to deceased donor kidney transplantation. Yet in spite of the excellent results of living kidney donation, the annual number of living kidney donors is declining in many countries, including the United States. In Israel, a non-profit organization, Matnat Chaim ("Gift of Life" in Hebrew), a faith-based initiative, has emerged as a major force for arranging living donor kidney transplantation mainly by facilitating altruistic living unrelated donor transplantation. A retrospective review of the records of live kidney donations facilitated by the Matnat Chaim organization and referred to Israel transplant centers, since the organization's inception in 2009, was performed and compared to published data from the Israel Ministry of Health. Matnat Chaim has facilitated 494 live kidney donations since its founding in February 2009 until the end of 2017. Of the 124 live kidney transplants performed in 2016, 111 (90%) were shown to be altruistic and unrelated. This large number of donations was associated with a doubling of the total number of kidney transplantations, performed in Israel (data published by the Israel Ministry of Health). The success of an Israel community organization in the promotion of kidney transplantation may serve as a model for other religious and non-religious communities worldwide.

Obesity is a pandemic in Mexico. The purpose of this study was to assess the environmental factors that have the strongest association with obesity and abdominal obesity among adults in Tijuana. Four neighborhoods differing in socioeconomic status were chosen. A questionnaire for weekly walking, social cohesion, satisfaction with their community, weekly income, and convenience store, education, family income, crime safety, pedestrian safety, street connectivity, walking/cycling facilities, and sociodemographic characteristics was administered. Weight, height, and waist circumference were measured. Univariate and multivariate binomial logistic regressions were conducted. Three hundred and twenty-two (322) individuals, 70% females with a mean age of 39 years, were assessed. The prevalence of obesity and abdominal obesity was 27% and 43.5% respectively. The odds ratio for obesity and abdominal obesity among those living in the lowest-income neighborhood was 2.4 and 7.8 respectively, compared with those living in a middle-class neighborhood. Residence in a low-income neighborhood was a predictor for obesity.

Modifiable behaviors during the first 1000 days (conception age 24 months) mediate Hispanic children's obesity disparities. We aimed to examine underlying reasons for early life obesity risk factors and identify potential early life intervention strategies. We conducted 7 focus groups with 49 Hispanic women who were pregnant or had children < age 24 months. Domains included influences on childhood obesity risk factors and future intervention ideas. We analyzed data with immersion-crystallization methods until no new themes emerged. Themes included coping with pregnancy may trump healthy eating and physical activity; early life weight gain is unrelated to later life obesity; fear of infant hunger drives bottle and early solids introduction; beliefs about infant taste promote early solids and sugary beverage introduction; and belief that screen time promotes infant development. Mothers identified physicians, nutritionists, and relatives as important health information sources and expressed interest in mobile technology and group or home visits for interventions. Opportunities exist in the first 1000 days to improve Hispanic mothers' understanding of the role of early life weight gain in childhood obesity and other obesity risk factors. Interventions that link health care and public health systems and include extended family may prevent obesity among Hispanic children.

This paper presents a new, comprehensive tool for communities to assess opportunities for active living and healthy eating and to mobilize all sectors of society to conquer obesity and chronic disease. Relevant existing tools and input from an expert panel were considered to draft the Community Healthy Living Index (CHLI). CHLI covers five major sectors where people live, work, learn, and play: schools, afterschools, work sites, neighborhoods, and the community-at-large. CHLI and the accompanying procedures enable community teams to assess programs, the physical environment, and policies related to healthy living and to plan improvement strategies. In 2008, with local YMCAs acting as conveners, community assessment teams from six US communities pilot-tested CHLI for cognitive response testing, inter-rater reliability, and implementation feasibility. CHLI was revised to reflect the test results. Pilot analyses demonstrated that the process was feasible, with most questions being interpreted as intended and showing substantial to almost perfect agreement between raters. The final CHLI is being disseminated nationally. Preliminary data illustrate CHLI obtains reliable results and is feasible to implement. CHLI is a promising tool for community-based prevention efforts to draw attention to opportunities for healthy living and create impetus for community changes.

In this paper we propose approaches to optimal scheduling of unrelated parallel machines with release dates. One approach is based on the scheme of dynamic programming modified with adaptive narrowing of search domain ensuring its computational effectiveness. We discussed complexity of the exact schedules synthesis and compared it with approximate, close to optimal, solutions. Also we explain how the algorithm works for the example of two unrelated parallel machines and five jobs with release dates. Performance results that show the efficiency of the proposed approach have been given.

Abstract Obesity is a major global public health concern. Immune responses implicated in obesity also control certain infections. We investigated the effects of high‐fat diet‐induced obesity (DIO) on infection with the Lyme disease bacterium Borrelia burgdorferi in mice. DIO was associated with systemic suppression of neutrophil‐ and macrophage‐based innate immune responses.

Obesity is a major global public health concern. Immune responses implicated in obesity also control certain infections. We investigated the effects of high-fat diet-induced obesity (DIO) on infection with the Lyme disease bacterium Borrelia burgdorferi in mice. DIO was associated with systemic suppression of neutrophil- and macrophage-based innate immune responses. These included bacterial uptake and cytokine production, and systemic, progressive impairment of bacterial clearance, and increased carditis severity. B. burgdorferi-infected mice fed normal diet also gained weight at the same rate as uninfected mice fed high-fat diet, toll-like receptor 4 deficiency rescued bacterial clearance defects, which greater in female than male mice, and killing of an unrelated bacterium (Escherichia coli) by bone marrow-derived macrophages from obese, B. burgdorferi-infected mice was also affected. Importantly, innate immune suppression increased with infection duration and depended on cooperative and synergistic interactions between DIO and B. burgdorferi infection.

Recent research has shown that neighborhood characteristics are associated with obesity prevalence. While food advertising in periodicals and television has been linked to overweight and obesity, it is unknown whether outdoor advertising is related to obesity. To test the association between outdoor food advertising and obesity, we analyzed telephone survey data on adults, aged 18-98, collected from 220 census tracts in Los Angeles and Louisiana. We linked self-reported information on BMI and soda consumption with a database of directly observed outdoor advertisements. The higher the percentage of outdoor advertisements promoting food or non-alcoholic beverages within a census tract, the greater the odds of obesity among its residents, controlling for age, race and educational status. For every 10% increase in food advertising, there was a 1.05 (95% CI 1.003 - 1.093, p<0.03) greater odds of being overweight or obese, controlling for other factors. Given these predictions, compared to an individual living in an area with no food ads, those living in areas in which 30% of ads were for food would have a 2.6% increase in the probability of being obese. There is a relationship between the percentage of outdoor food advertising and overweight/obesity.

An increase in the prevalence of pediatric type 2 diabetes mellitus (T2DM) has been reported by numerous studies in the United States during the past two decades. Available data from Europe are scarce, but also suggest the rising prevalence of this disease in overweight children. The aim of this study was to determine the prevalence of previously undiagnosed T2DM, impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) in a clinic cohort of otherwise healthy overweight and obese Caucasian children and adolescents living in Serbia. The study group consisted of 301 subjects (176 girls, 125 boys) aged 5.2-18.9 years, with body mass index >90th percentile. Oral glucose tolerance test was performed in all subjects. Previously undiagnosed T2DM was discovered in 0.3% (n=1) and impaired glucose regulation in 15.9% (n=48) of the subjects. Isolated IFG was detected in 4.3% (n=13), isolated IGT in 8.3% (n=25) and combined IFG and IGT in 3.3% (n=10) of the subjects. Disturbances of glucose metabolism were present in a substantial number of the subjects, which emphasizes the need for prevention and treatment of childhood obesity.

Most of the studies and interventions are targeted to address undernutrition, but childhood obesity has become a silent killer among children. Developing countries, including Turkey, could recognize the importance of the issue now and have begun to discuss the necessity of studies on this subject. Therefore, this study aims to examine the prevalence of obesity among pre-school children in Turkey. The data source of this study is the Turkey Demographic and Health Survey (TDHS)-2013. The TDHS-2013 was a sample study to gather information about the fertility levels and changes in them, infant and child mortality, family planning, and maternal and infant health at the national level. Overweight/obesity for height was 8.6% and 6.6% for age. Overweight/obesity problems are mostly observed in the West and are higher in urban areas. Overweight/obesity decreases with increasing age. There is a positive correlation between overweight/obesity and maternal educational level. As the household welfare level increases, overweight/obesity increases in pre-school children. Female children are at higher risk of overweight/obesity than males. As birth order increases, overweight/obesity decreases. Children living in other regions have overweight/obesity problems more than the pre-school children living in the East. This study speculates that obesity appears to be a major problem among pre-school children in Turkey. Based on the findings, the current situation of overweight/obesity among pre-school children is so close to many developing and developed countries, whose obesity levels are a greater concern. This finding demonstrates that effective interventions of obesity should begin as early as infancy in Turkey, as it is a developing country.

The effects of environmental temperature on blood pressure and hormones in obese subjects in Japan were compared in two seasons: summer vs winter. Five obese (BMI, 32 ± 5 kg/m2) and five non-obese (BMI, 23 ±3 kg/m2) men participated in this experiment at latitude 35°10' N and longitude 136°57.9' E. The average environmental temperature was 29 ± 1 °C in summer and 3 ± 1 °C in winter. Blood samples were analyzed for leptin, ghrelin, catecholamines, thyroid stimulating hormone (TSH), free thyroxine (fT4), free triiodothyronine (fT3), total cholesterol, triglycerides, insulin and glucose. Blood pressure was measured over the course of 24 h in summer and winter. A Japanese version of the Profile of Mood States (POMS) questionnaire was also administered each season. Systolic and diastolic blood pressures in obese men were significantly higher in winter (lower environmental temperatures) than in summer (higher environmental temperatures). Noradrenaline and dopamine concentrations were also significantly higher at lower environmental temperatures in obese subjects, but ghrelin, TSH, fT3, fT4, insulin and glucose were not significantly different in summer and winter between obese and non-obese subjects. Leptin, total cholesterol and triglyceride concentrations were significantly higher in winter in obese than non-obese men. Results from the POMS questionnaire showed a significant rise in Confusion at lower environmental temperatures (winter) in obese subjects. In this pilot study, increased blood pressure may have been due to increased secretion of noradrenaline in obese men in winter, and the results suggest that blood pressure control in obese men is particularly important in winter.

Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder associated with maladaptive social behavior, hyperphagia and morbid obesity. Orexin A is a hypothalamic neuropeptide important as a homeostatic regulator of feeding behavior and in energy metabolism through actions in the lateral hypothalamus. Dysregulation of orexin signaling may contribute to behavioral problems and hyperphagia seen in PWS and we sought to assess orexin A levels in PWS relative to controls children. Morning fasting plasma orexin A levels were analyzed in 23 children (aged 5-11 years) with genetically confirmed PWS and 18 age and gender matched healthy unrelated siblings without PWS. Multiplex immune assays utilized the Milliplex Human Neuropeptide Magnetic panel and the Luminex platform. Natural log-transformed orexin A data were analyzed using general linear model adjusting for diagnosis, gender, age, total body fat, and body mass index (BMI). Plasma orexin A levels were significantly higher (P < 0.006) in children with PWS (average ±SD = 1,028 pg/ml ± 358) compared with unrelated siblings (average ±SD = 609 pg/ml ± 351; P < 0.001). Orexin A levels correlated with age in females and were significantly elevated in PWS even after these effects were controlled. These findings support the hypothesis that dysregulation of orexin signaling may contribute to behavioral problems and hyperphagia in PWS. Further studies are warranted to better understand the complex relationship between orexin A levels and the problematic behaviors consistently found in individuals with PWS. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

South Asian men living in the UK have higher rates of central obesity and Type 2 Diabetes Mellitus (T2DM) compared with their white British counterparts. Physical activity (PA) and sedentary time (ST) are important risk factors for the development of T2DM. The purpose of this study was to objectively measure PA, ST, and to explore the factors influencing these behaviours in this high-risk population. A mixed-methods cross-sectional research design was employed, including the quantification of PA and ST using the self-report International Physical Activity Questionnaire (IPAQ)-long form and accelerometry in overweight and obese UK South Asian men (n = 54), followed by semi-structured interviews in a purposive sub-sample to explore the factors influencing PA and ST (n = 31). Accelerometer-derived moderate-to-vigorous PA (MVPA) and ST were 298.9 ± 186.6 min/week and 551.4 ± 95.0 min/day, respectively. IPAQ-derived MVPA was significantly lower than accelerometer-derived MVPA (p < 0.001). IPAQ-derived ST was significantly higher than accelerometer-derived ST (p < 0.001). Lack of time and family commitments were identified as the main barriers to being more physically active, with group exercise identified as an important facilitator to being more active. A cultural norm of focusing on promoting education over sport participation during childhood was identified as an important factor influencing long-term PA behaviours. Work commitments and predominantly sedentary jobs were identified as the main barriers to reducing ST. Healthcare professionals and researchers need to consider the socio-cultural factors which affect PA engagement in overweight and obese South Asian men living in the UK, to ensure that advice and future interventions are tailored to address the needs of this population.

Several studies have examined associations between the food retail environment and obesity, though virtually no work has been done in the urban South, where obesity rates are among the highest in the country. This study assessed associations between access to food retail outlets and obesity in New Orleans. Data on individual characteristics and body weight were collected by telephone interviews from a random sample of adults (N = 3,925) living in New Orleans in 2004-2005. The neighborhood of each individual was geo-mapped by creating a 2-km buffer around the center point of the census tract in which they lived. Food retailer counts were created by summing the total number of each food store type and fast food establishment within this 2-km neighborhood. Hierarchical linear models assessed associations between access to food retailers and obesity status. After adjusting for individual characteristics, each additional supermarket in a respondent's neighborhood was associated with a reduced odds for obesity (OR 0.93, 95% CI 0.88-0.99). Fast food restaurant (OR 1.01, 95% CI 1.00-1.02) and convenience store (OR 1.01, 95% CI 1.00-1.02) access were each predictive of greater obesity odds. An individual's access to food stores and fast food restaurants may play a part in determining weight status. Future studies with longitudinal and experimental designs are needed to test whether modifications in the food environment may assist in the prevention of obesity.

Globally, older people are living independently either alone or with their spouse, population continues to age. In Singapore, some may live with an unrelated older person in a public rental apartment. In Asia, these older people are associated with increased risks of poor health and social isolation, have poorer social support and a poor quality of life. Few studies have explored why these older people choose such living arrangements, the challenges they encountered and what has helped or may help them overcome these challenges. To explore older people's experiences of living independently or with an unrelated older person. This descriptive qualitative study involved face-to-face interviews with 25 informants, 65 years or older in Singapore. Thematic analysis was adopted. Five themes emerged: (1) making own choice--participants decided to live apart from their families, (2) contending with concerns--the availability of external resources for participants was shrinking, (3) coping with the available assistance--depending on available external resources from the community, (4) holding on to their values--participants rely on their internal resources to manage, and (5) preparing for the inevitable--participants were planning for their final years of life and for their death. Older people have such living arrangements for many reasons. They attain well-being and quality of life by devising strategies, tapping on their limited external resources and relying on their values to manage their diminishing resources and the foreseeable death. Understanding older people's experiences may help nurses and health professionals to develop health promotion programmes that support older people's everyday needs and help them to stay healthy. Public health policy must support older people to live in a safe environment near their extended family to reduce their need to relocate. © 2015 International Council of Nurses.

Cross-sectional analysis of the Validity and Reliability of Korean Frailty Index and the Validity and Reliability of the Kaigo-Yobo Checklist in Korean Elderly studies. Six welfare facilities operated by government in South Korea. Four hundred eighty-seven community-dwelling individuals (157 males, 330 females) >65 years of age. Dynapenic component of the EWGSOP sarcopenia was defined as usual gait speed <0.8 m/s or grip strength lower than cut-off value (male <25.3 kg, female <12.0 kg). Obesity was defined as body mass index ≥27.5 kg/m(2). ADL were assessed using the Barthel index. There were 14 obese with dynapenic component cases (2 males, 12 females) of the 487 participants. Interaction of dynapenia and obesity was significant on multivariate generalized linear model analysis (P = .015). Dynapenic component of the EWGSOP sarcopenia and obesity in the elderly is associated with multiplicative interactions rather than additive interactions in ADL.

OBJECTIVE To examine the incidence and reverse of obesity among young low-income children and variations across population subgroups. METHODS We included 1.2 million participants in federally funded child health and nutrition programs who were 0 to 23 months old in 2008 and were followed up 24 to 35 months later in 2010–2011. Weight and height were measured. Obesity at baseline was defined as gender-specific weight-for-length ≥95th percentile on the 2000 Centers for Disease Control and Prevention growth charts. Obesity at follow-up was defined as gender-specific BMI-for-age ≥95th percentile. We used a multivariable log-binomial model to estimate relative risk of obesity adjusting for gender, baseline age, race/ethnicity, duration of follow-up, and baseline weight-for-length percentile. RESULTS The incidence of obesity was 11.0% after the follow-up period. The incidence was significantly higher among boys versus girls and higher among children aged 0 to 11 months at baseline versus those older. Compared with non-Hispanic whites, the risk of obesity was 35% higher among Hispanics and 49% higher among American Indians (AIs)/Alaska Natives (ANs), but 8% lower among non-Hispanic African Americans. Among children who were obese at baseline, 36.5% remained obese and 63.5% were nonobese at follow-up. The proportion of reversing of obesity was significantly lower among Hispanics and AIs/ANs than that among other racial/ethnic groups. CONCLUSIONS The high incidence underscores the importance of early-life obesity prevention in multiple settings for low-income children and their families. The variations within population subgroups suggest that culturally appropriate intervention efforts should be focused on Hispanics and AIs/ANs. PMID:24276843

Pathophysiology and Genetics of Bronchiectasis Unrelated to Cystic Fibrosis.

PubMed

Nikolic, Aleksandra

2018-05-12

Bronchiectasis is characterized by deregulated inflammatory response and recurrent bacterial infection resulting in progressive lung damage and an irreversible dilatation of bronchi and bronchioles. Generally accepted model of the development of bronchiectasis is the "vicious cycle hypothesis" that proposes compromising of the mucociliary clearance by an initial event, which leads to the infection of the respiratory tract followed by further impairment of mucociliary function, bacterial proliferation, and more inflammation. Bronchiectasis is a very common symptom in patients with cystic fibrosis (CF), while bronchiectasis unrelated to CF is heterogeneous pathology of unknown cause with a large number of potential contributory factors and poorly understood pathogenesis. It is presumed that bronchiectasis unrelated to CF is a multifactorial condition predisposed by genetic factors. Different molecules have been implicated in the onset and development of idiopathic bronchiectasis, as well as modulation of the disease severity and response to therapy. Most of these molecules are involved in the processes that contribute to the homeostasis of the lung tissue, especially mucociliary clearance, protease-antiprotease balance, and immunomodulation. Evaluation of the studies performed towards investigation of the role these molecules play in bronchiectasis identifies genetic variants that may be of potential importance for clinical management of the disease, and also of interest for future research efforts. This review focuses on the molecules with major roles in lung homeostasis and their involvement in bronchiectasis unrelated to CF.

Allogeneic hematopoietic cell transplantation has an established role in the treatment of adults with acute lymphoblastic leukemia whose survival when recipients of grafts from adult unrelated donors approaches that of recipients of grafts from sibling donors. Our aim was to determine the role of mismatched unrelated cord blood grafts in transplantation for 802 adults with acute lymphoblastic leukemia in first or second complete remission. Using Cox regression we compared outcomes after 116 mismatched single or double cord blood transplants, 546 peripheral blood progenitor cell transplants and 140 bone marrow transplants. The characteristics of the recipients and their diseases were similar except cord blood recipients were younger, more likely to be non-Caucasians and more likely to have a low white blood cell count at diagnosis. There were differences in donor-recipient human leukocyte antigen-match depending on the source of the graft. Most adult donor transplants were matched at the allele-level considering human leukocyte antigens-A, -B, -C and –DRB1. In contrast, most cord blood transplants were mismatched and considered antigen-level matching; 57% were mismatched at two loci and 29% at one locus whereas only 29% of adult donor transplants were mismatched at one locus and none at two loci. There were no differences in the 3-year probabilities of survival between recipients of cord blood (44%), matched adult donor (44%) and mismatched adult donor (43%) transplants. Cord blood transplants engrafted slower and were associated with less grade 2–4 acute but similar chronic graft-versus-host disease, relapse, and transplant-related mortality. The survival of cord blood graft recipients was similar to that of recipients of matched or mismatched unrelated adult donor grafts and so cord blood should be considered a valid alternative source of stem cells for adults with acute lymphoblastic leukemia in the absence of a matched unrelated adult donor.

The present study reports findings from a study of preschool-age Inuit children living in the Arctic regions of Canada and Greenland. We compare stature and obesity measures using cutoffs from the Centers for Disease Control and the International Obesity Task Force references. The sample is comprised of 1121 Inuit children (554 boys and 567 girls) aged 3-5 years living in Nunavut (n=376) and Nunavik (n=87), Canada, in the capital city of Nuuk, Greenland (n=86), and in Greenland's remaining towns and villages (n=572). Greenland Inuit children were significantly taller than their Canadian counterparts, with greatest height and weight observed among children from Nuuk. Overall prevalence of stunting was low with the three cutoffs yielding similar values for height-for-age z-scores. Obesity prevalence was higher among Canadian Inuit children than their Greenland counterparts. Inuit children have stature values consistent with those of the Centers for Disease Control reference and low prevalence of stunting, though geographic variability in mean stature values between Canadian and Greenlandic samples likely reflects differences in both socioeconomic status and genetic admixture. Obesity prevalence is high among both Canadian and Greenland Inuit preschoolers, with children living in the city of Nuuk exhibiting lower obesity prevalence than children living in either Nunavut or Nunavik, Canada or Greenland's towns and villages. Varying obesity prevalence may reflect varying degrees of food security in remote locations as well as the influence of stature and sitting height which have not been well studied in young Inuit children.

The balanced mind: the variability of task-unrelated thoughts predicts error monitoring

Self-generated thoughts unrelated to ongoing activities, also known as “mind-wandering,” make up a substantial portion of our daily lives. Reports of such task-unrelated thoughts (TUTs) predict both poor performance on demanding cognitive tasks and blood-oxygen-level-dependent (BOLD) activity in the default mode network (DMN). However, recent findings suggest that TUTs and the DMN can also facilitate metacognitive abilities and related behaviors. To further understand these relationships, we examined the influence of subjective intensity, ruminative quality, and variability of mind-wandering on response inhibition and monitoring, using the Error Awareness Task (EAT). We expected to replicate links between TUT and reduced inhibition, and explored whether variance in TUT would predict improved error monitoring, reflecting a capacity to balance between internal and external cognition. By analyzing BOLD responses to subjective probes and the EAT, we dissociated contributions of the DMN, executive, and salience networks to task performance. While both response inhibition and online TUT ratings modulated BOLD activity in the medial prefrontal cortex (mPFC) of the DMN, the former recruited a more dorsal area implying functional segregation. We further found that individual differences in mean TUTs strongly predicted EAT stop accuracy, while TUT variability specifically predicted levels of error awareness. Interestingly, we also observed co-activation of salience and default mode regions during error awareness, supporting a link between monitoring and TUTs. Altogether our results suggest that although TUT is detrimental to task performance, fluctuations in attention between self-generated and external task-related thought is a characteristic of individuals with greater metacognitive monitoring capacity. Achieving a balance between internally and externally oriented thought may thus aid individuals in optimizing their task performance. PMID:24223545

Chronic bystander infections and immunity to unrelated antigens

2012-01-01

Chronic infections with persistent pathogens such as helminths, mycobacteria, Plasmodium and hepatitis viruses affect more than a third of the human population and are associated with increased susceptibility to other pathogens as well as reduced vaccine efficacy. Although these observations suggest an impact of chronic infections in modulating immunity to unrelated antigens, little is known regarding the underlying mechanisms. Here, we summarize evidence of the most prevalent infections affecting immunity to unrelated pathogens and vaccines, and discuss potential mechanisms of how different bystander chronic infections might impact immune responses. We suggest that bystander chronic infections affect different stages of host responses and may impact transmission of other pathogens, recognition and innate immune responses, priming and differentiation of adaptive effector responses, as well as the development and maintenance of immunological memory. Further understanding of the immunological effects of co-infection should provide opportunities to enhance vaccine efficacy and control infectious diseases. PMID:23084915

The Latin American (LA) population in Spain is ever increasing in size and is perfectly integrated into the social structure. The objectives were to analyze the attitude of citizens, born in Latin America and living in Spain, toward living kidney donation (LKD) and to determine the psychosocial variables affecting this attitude. A sample of LA residents living in Spain was obtained randomly in 2010 and stratified according to the respondent's nationality (n = 1314). Attitude was evaluated using a validated questionnaire ("Proyecto Colaborativo Internacional Donante sobre Donación de Vivo Renal" Ríos). The survey was self-administered and completed anonymously. The questionnaire completion rate was 86% (n = 1.132). A total of 89% (n = 1003) were in favor of related living donation, and 30% if the donation were unrelated. The variables associated with attitude toward LKD were as follows: sex (p = 0.043); marital status (p = 0.013); previous experience of organ donation (p = 0.009); attitude toward deceased organ donation (p < 0.001); a respondent's belief that he or she could be a possible recipient of a future transplant (p < 0.001); knowledge of a partner's opinion (p = 0.021); family discussion about organ donation (p = 0.001); knowledge of the view of one's religion toward donation (p < 0.001); concern about "mutilation" after donation (p = 0.004); and evaluation of the risk from living donation (p = 0.036). The attitude of LA citizens residing in Spain was favorable both toward related LKD and unrelated living donation. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Minimum nonuniform graph partitioning with unrelated weights

2017-12-01

We give a bi-criteria approximation algorithm for the Minimum Nonuniform Graph Partitioning problem, recently introduced by Krauthgamer, Naor, Schwartz and Talwar. In this problem, we are given a graph G=(V,E) and k numbers ρ_1,\\dots, ρ_k. The goal is to partition V into k disjoint sets (bins) P_1,\\dots, P_k satisfying \\vert P_i\\vert≤ ρi \\vert V\\vert for all i, so as to minimize the number of edges cut by the partition. Our bi-criteria algorithm gives an O(\\sqrt{log \\vert V\\vert log k}) approximation for the objective function in general graphs and an O(1) approximation in graphs excluding a fixed minor. The approximate solution satisfies the relaxed capacity constraints \\vert P_i\\vert ≤ (5+ \\varepsilon)ρi \\vert V\\vert. This algorithm is an improvement upon the O(log \\vert V\\vert)-approximation algorithm by Krauthgamer, Naor, Schwartz and Talwar. We extend our results to the case of 'unrelated weights' and to the case of 'unrelated d-dimensional weights'. A preliminary version of this work was presented at the 41st International Colloquium on Automata, Languages and Programming (ICALP 2014). Bibliography: 7 titles.

2014-02-01

To compare the associations between food environment at the individual level, socioeconomic status (SES) and obesity rates in two cities: Seattle and Paris. Analyses of the SOS (Seattle Obesity Study) were based on a representative sample of 1340 adults in metropolitan Seattle and King County. The RECORD (Residential Environment and Coronary Heart Disease) cohort analyses were based on 7131 adults in central Paris and suburbs. Data on sociodemographics, health and weight were obtained from a telephone survey (SOS) and from in-person interviews (RECORD). Both studies collected data on and geocoded home addresses and food shopping locations. Both studies calculated GIS (Geographic Information System) network distances between home and the supermarket that study respondents listed as their primary food source. Supermarkets were further stratified into three categories by price. Modified Poisson regression models were used to test the associations among food environment variables, SES and obesity. Physical distance to supermarkets was unrelated to obesity risk. By contrast, lower education and incomes, lower surrounding property values and shopping at lower-cost stores were consistently associated with higher obesity risk. Lower SES was linked to higher obesity risk in both Paris and Seattle, despite differences in urban form, the food environments and in the respective systems of health care. Cross-country comparisons can provide new insights into the social determinants of weight and health.

Are parents aware that their children are overweight or obese?

2007-01-01

OBJECTIVE To compare children’s actual weight status with their parents’ perceptions of their weight status. DESIGN Cross-sectional study, including a self-administered questionnaire. SETTING Seven elementary schools in Middlesex-London, Ont. PARTICIPANTS A convenience sample of pupils in grades 4 to 6 and their parents. Of the 770 child-parent pairs targeted, 355 pairs participated in the study. MAIN OUTCOME MEASURES Children’s weight, height, and body mass index (BMI). Parents’ perceptions of their children’s weight status, family demographics, and parents’ self-reported body weight and height. The United States Centers for Disease Control’s BMI-for-age references were used to define children’s weight status (underweight, overweight, or obese). RESULTS Response rate was 46%. Children’s actual weight status (ie, 29.9% overweight or obese and 1.4% underweight) was different from their parents’ perceptions of their weight status (ie, 18.3% overweight or obese and 17.2% slightly underweight or underweight). Factors suchas children’s sex and ethnicity and mothers’ weight influenced parents’ ability to recognize their children’s weight status. Parents’ misperceptions of their children’s weight status seemed to be unrelated to their levelsof education, their family income, or their children’s ages. CONCLUSION A large proportion of parents did not recognize that their children were overweight or obese. Effective public health strategies to increase parents’ awareness of their children’s weight status could be the first key steps in an effort to prevent childhood obesity. PMID:17872878

In this study the prevalence of obesity and the demographic factors associated with it were analysed on 290 adult Bahraini individuals, of whom 137 were males and 153 were females. The overweight and obesity prevalence rates, using the Body Mass Index (BMI) as a criterion, were 26% and 16% in males and 29% and 31% in females, respectively. The prevalence of underweight (BMI < 20) was 16.8% and 11.8% in the males and females respectively. The mean body fat percentage of females, calculated from the skinfold measurements, was 35%; the fat percentage of males was 18.6%. Bahraini women had greater fat deposition in the subscapular region than the amount reported for American women. Females and males living in urban areas had a greater tendency to be obese than those residing in rural areas. Marriage, ownership of a car as well as a large family ( > 7 members) were positively associated with obesity; unmarried women were more likely to be underweight than married women. The educational level was not associated with obesity in either the males or females. The age of adult females was not found to be associated with obesity, whereas in males the incidence of obesity was more frequent among those who were 50 years of age and above than under 50 years of age. Family monthly income was not associated with the incidence of obesity. The high prevalence of overweight and obesity in the women reported in this study and the difference in the distribution of body fat suggest that genetics may be a determinant factor of this disorder in Bahrainis but certainly social factors are also important.

We studied adults with acute myeloid leukemia (AML) after haploidentical (n = 192) and 8/8 HLA-matched unrelated donor (n = 1982) transplantation. Haploidentical recipients received calcineurin inhibitor (CNI), mycophenolate, and posttransplant cyclophosphamide for graft-versus-host disease (GVHD) prophylaxis; 104 patients received myeloablative and 88 received reduced intensity conditioning regimens. Matched unrelated donor transplant recipients received CNI with mycophenolate or methotrexate for GVHD prophylaxis; 1245 patients received myeloablative and 737 received reduced intensity conditioning regimens. In the myeloablative setting, day 30 neutrophil recovery was lower after haploidentical compared with matched unrelated donor transplants (90% vs 97%, P = .02). Corresponding rates after reduced intensity conditioning transplants were 93% and 96% (P = .25). In the myeloablative setting, 3-month acute grade 2-4 (16% vs 33%, P < .0001) and 3-year chronic GVHD (30% vs 53%, P < .0001) were lower after haploidentical compared with matched unrelated donor transplants. Similar differences were observed after reduced intensity conditioning transplants, 19% vs 28% (P = .05) and 34% vs 52% (P = .002). Among patients receiving myeloablative regimens, 3-year probabilities of overall survival were 45% (95% CI, 36-54) and 50% (95% CI, 47-53) after haploidentical and matched unrelated donor transplants (P = .38). Corresponding rates after reduced intensity conditioning transplants were 46% (95% CI, 35-56) and 44% (95% CI, 0.40-47) (P = .71). Although statistical power is limited, these data suggests that survival for patients with AML after haploidentical transplantation with posttransplant cyclophosphamide is comparable with matched unrelated donor transplantation.

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

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

Genomic copy number variations (CNVs) have been strongly implicated as important genetic factors for obesity. A recent genome-wide association study identified a novel variant, rs12444979, which is in high linkage disequilibrium with CNV 16p12.3, for association with obesity in Europeans. The aim of this study was to directly examine the relationship between the CNV 16p12.3 and obesity phenotypes, including body mass index (BMI) and body fat mass. Subjects were a multi-ethnic sample, including 2286 unrelated subjects from a European population and 1627 unrelated Han subjects from a Chinese population. Body fat mass was measured using dual energy X-ray absorptiometry. Using Affymetrix Genome-Wide Human SNP Array 6.0, we directly detected CNV 16p12.3, with the deletion frequency of 27.26 and 0.8% in the European and Chinese populations, respectively. We confirmed the significant association between this CNV and obesity (BMI: P=1.38 × 10(-2); body fat mass: P=2.13 × 10(-3)) in the European population. Less copy numbers were associated with lower BMI and body fat mass, and the effect size was estimated to be 0.62 (BMI) and 1.41 (body fat mass), respectively. However, for the Chinese population, we did not observe significant association signal, and the frequencies of this deletion CNV are quite different between the European and Chinese populations (P<0.001). Our findings first suggest that CNV 16p12.3 might be ethnic specific and cause ethnic phenotypic diversity, which may provide some new clues into the understanding of the genetic architecture of obesity.

To determine the prevalence of and factors associated with childhood overweight and obesity among a cohort of children 7-8 years of age in Peru. This was a cross-sectional secondary analysis of data from the Young Lives longitudinal study of childhood poverty. The sample was a cohort of 1 737 children 7-8 years of age in 2009. Prevalence of overweight and obesity was assessed using body mass index-forage Z-scores. Logistic regression was used to determine associations with a number of individual, household, and community factors. Prevalences of overweight and obesity were 19.2% and 8.6%, respectively. A prevalence of 32.0% and 23.5% overweight and obesity was found among males and females, respectively. High socioeconomic status, living in Lima, having a mother who was overweight or obese, being male, and being an only child or having only one sibling were associated with being overweight and obese at this age. This study shows a high prevalence of childhood and maternal overweight and obesity in Peru. In contrast to findings in many high-income countries, the findings in Peru indicate that children from wealthier households were more likely to be overweight or obese than those from poorer households. In addition, there is something particularly obesogenic about the Lima environment that merits further investigation, and several key issues to consider when targeting future interventions and research.

2015-01-01

Objective To explore outcomes and measures of success that matter most to 'positive outlier' children who improved their body mass index (BMI) despite living in obesogenic neighborhoods. Methods We collected residential address and longitudinal height/weight data from electronic health records of 22,657 children ages 6–12 years in Massachusetts. We defined obesity “hotspots” as zip codes where >15% of children had a BMI ≥95th percentile. Using linear mixed effects models, we generated a BMI z-score slope for each child with a history of obesity. We recruited 10–12 year-olds with negative slopes living in hotspots for focus groups. We analyzed group transcripts and discussed emerging themes in iterative meetings using an immersion/crystallization approach. Results We reached thematic saturation after 4 focus groups with 21 children. Children identified bullying and negative peer comparisons related to physical appearance, clothing size, and athletic ability as motivating them to achieve a healthier weight, and they measured success as improvement in these domains. Positive relationships with friends and family facilitated both behavior change initiation and maintenance. Conclusions The perspectives of positive outlier children can provide insight into children’s motivations leading to successful obesity management. Practice implications: Child/family engagement should guide the development of patient-centered obesity interventions. PMID:26166630

Urban green space and obesity in older adults: Evidence from Ireland.

PubMed

Dempsey, Seraphim; Lyons, Seán; Nolan, Anne

2018-04-01

We examine the association between living in an urban area with more or less green space and the probability of being obese. This work involves the creation of a new dataset which combines geo-coded data at the individual level from the Irish Longitudinal Study on Ageing with green space data from the European Urban Atlas 2012. We find evidence suggestive of a u-shaped relationship between green space in urban areas and obesity; those living in areas with the lowest and highest shares of green space within a 1.6 km buffer zone have a higher probability of being classified as obese (BMI [Formula: see text]). The unexpected result that persons in areas with both the lowest and highest shares of green space have a higher probability of being obese than those in areas with intermediate shares, suggests that other characteristics of urban areas may be mediating this relationship.

The purpose of this study was to investigate the association between mean body mass index (BMI) and prevalence of obesity in adult populations living in Brazilian State capitals. An ecological study was conducted, using data from the National Household Budget Survey conducted in July 2002 through June 2003, including a representative sample of 48.470 households. Pearson's correlation and linear regression coefficients were estimated in order to define the relationships of mean BMI and sex-specific, age standardized obesity prevalence (BMI ≥ 30.0 kg/m(2)) in adults aged 20 to 59 years. Stronger correlations between BMI and prevalence of obesity were observed in women (r = 0.9; p < 0.001) than in men (r = 0.6; p = 0.001) in all analyzes. A reduction of one unit in mean BMI predicted a decline in the prevalence of obesity of about 4.0% (95% CI: 1.7-6.3) in men, and 3.4% (95% CI: 2.6-4.3) in women. We found a correlation between BMI and prevalence of obesity, particularly among women, suggesting that population-based strategies would be effective to reduce the prevalence of obesity in adult populations living in Brazilian state capitals.

Lim, Weonjeong; Thomas, Kamala S.; Bardwell, Wayne A.; Dimsdale, Joel E.

2009-01-01

The authors asked which obesity measurements were associated with depressive symptoms, whether this relationship differed by gender, and whether controlling for fatigue and response bias affected the relationship. A sample of 129 subjects (66 men, 63 women), with a mean age of 36.9 years and a mean Body Mass Index (BMI) of 26.4 participated in the study. Depressive symptoms, levels of fatigue, response bias, and anthropometrics were assessed. In women, but not men, BMI and percent of ideal body weight were related to depression. However, percent of body fat did not show a relationship with depression after controlling for fatigue and response bias. These findings suggest that women’s depressive symptoms are more influenced by body size than body fat composition, whereas men’s depressive symptoms seem to be unrelated to obesity. PMID:18212172

Gene-Diet Interaction and Precision Nutrition in Obesity

Heianza, Yoriko; Qi, Lu

2017-01-01

The rapid rise of obesity during the past decades has coincided with a profound shift of our living environment, including unhealthy dietary patterns, a sedentary lifestyle, and physical inactivity. Genetic predisposition to obesity may have interacted with such an obesogenic environment in determining the obesity epidemic. Growing studies have found that changes in adiposity and metabolic response to low-calorie weight loss diets might be modified by genetic variants related to obesity, metabolic status and preference to nutrients. This review summarized data from recent studies of gene-diet interactions, and discussed integration of research of metabolomics and gut microbiome, as well as potential application of the findings in precision nutrition.

Objective. To investigate whether obesity alters the sensory motor integration process and movement outcome during a visual rhythmic coordination task. Methods. 88 participants (44 obese and 44 matched control) sat on a chair equipped with a wrist pendulum oscillating in the sagittal plane. The task was to swing the pendulum in synchrony with a moving visual stimulus displayed on a screen. Results. Obese participants demonstrated significantly ( p < 0.01) higher values for continuous relative phase (CRP) indicating poorer level of coordination, increased movement variability ( p < 0.05), and a larger amplitude ( p < 0.05) than their healthy weight counterparts. Conclusion. These results highlight the existence of visual sensory integration deficiencies for obese participants. The obese group have greater difficulty in synchronizing their movement with a visual stimulus. Considering that visual motor coordination is an essential component of many activities of daily living, any impairment could significantly affect quality of life.

Genetic determinants of Alzheimer disease (AD) have not been comprehensively examined in Caribbean Hispanics, a population in the United States in whom the frequency of AD is higher compared with non-Hispanic whites. To identify variant alleles in genes related to familial early-onset AD among Caribbean Hispanics. Family-based case series conducted in 1998-2001 at an AD research center in New York, NY, and clinics in the Dominican Republic. Among 206 Caribbean Hispanic families with 2 or more living members with AD who were identified, 19 (9.2%) had at least 1 individual with onset of AD before the age of 55 years. The entire coding region of the presenilin 1 gene and exons 16 and 17 of the amyloid precursor protein gene were sequenced in probands from the 19 families and their living relatives. A G-to-C nucleotide change resulting in a glycine-alanine amino acid substitution at codon 206 (Gly206Ala) in exon 7 of presenilin 1 was observed in 23 individuals from 8 (42%) of the 19 families. A Caribbean Hispanic individual with the Gly206Ala mutation and early-onset familial disease was also found by sequencing the corresponding genes of 319 unrelated individuals in New York City. The Gly206Ala mutation was not found in public genetic databases but was reported in 5 individuals from 4 Hispanic families with AD referred for genetic testing. None of the members of these families were related to one another, yet all carriers of the Gly206Ala mutation tested shared a variant allele at 2 nearby microsatellite polymorphisms, indicating a common ancestor. No mutations were found in the amyloid precursor protein gene. The Gly206Ala mutation was found in 8 of 19 unrelated Caribbean Hispanic families with early-onset familial AD. This genetic change may be a prevalent cause of early-onset familial AD in the Caribbean Hispanic population.

Maple syrup urine disease (MSUD) is an inherited disorder of branched chain ketoacid (BCKA) oxidation associated with episodic and chronic brain disease. Transplantation of liver from an unrelated deceased donor restores 9-13% whole-body BCKA oxidation capacity and stabilizes MSUD. Recent reports document encouraging short-term outcomes for MSUD patients who received a liver segment from mutation heterozygous living related donors (LRDT). To investigate effects of living related versus deceased unrelated grafts, we studied four Brazilian MSUD patients treated with LRDT who were followed for a mean 19 ± 12 postoperative months, and compared metabolic and clinical outcomes to 37 classical MSUD patients treated with deceased donor transplant. Patient and graft survival for LRDT were 100%. Three of 4 MSUD livers were successfully domino transplanted into non-MSUD subjects. Following LRDT, all subjects resumed a protein-unrestricted diet as mean plasma leucine decreased from 224 ± 306 μM to 143 ± 44 μM and allo-isoleucine decreased 91%. We observed no episodes of hyperleucinemia during 80 aggregate postoperative patient-months. Mean plasma leucine:isoleucine:valine concentration ratios were ~2:1:4 after deceased donor transplant compared to ~1:1:1.5 following LRDT, resulting in differences of predicted cerebral amino acid uptake. Mutant heterozygous liver segments effectively maintain steady-state BCAA and BCKA homeostasis on an unrestricted diet and during most catabolic states, but might have different metabolic effects than grafts from unrelated deceased donors. Neither living related nor deceased donor transplant affords complete protection from metabolic intoxication, but both strategies represent viable alternatives to nutritional management.

The recent World Health Organization (WHO) agreement on the standardized classification of overweight and obese, based on body mass index (BMI), allows a comparable analysis of prevalence rates worldwide for the first time. In Asia, however, there is a demand for a more limited range for normal BMIs (i.e., 18.5 to 22.9 kg/m(2) rather than 18.5 to 24.9 kg/m(2)) because of the high prevalence of comorbidities, particularly diabetes and hypertension. In children, the International Obesity Task-Force age-, sex-, and BMI-specific cutoff points are increasingly being used. We are currently evaluating BMI data globally as part of a new millennium analysis of the Global Burden of Disease. WHO is analyzing data in terms of 20 or more principal risk factors contributing to the primary causes of disability and lost lives in the 191 countries within the WHO. The prevalence rates for overweight and obese people are different in each region, with the Middle East, Central and Eastern Europe, and North America having higher prevalence rates. In most countries, women show a greater BMI distribution with higher obesity rates than do men. Obesity is usually now associated with poverty, even in developing countries. Relatively new data suggest that abdominal obesity in adults, with its associated enhanced morbidity, occurs particularly in those who had lower birth weights and early childhood stunting. Waist measurements in nationally representative studies are scarce but will now be needed to estimate the full impact of the worldwide obesity epidemic.

The prevalences of overweight and obesity have increased dramatically in the last two decades in the adult and children population. The Organization for Cooperation and Economic Development reported in 2010 that Mexico ranks first worldwide in childhood obesity. The 2006 National Health and Nutrition Survey reported that one of every three teenagers are overweight and obese. In the last decades, pediatric hospitals in different parts of the world reported the prevalence of secondary malnutrition, since in those days overweight and obesity did not represent health problems. Currently, the prevalence of overweight and obesity has been scarcely studied in pediatric hospitals. In the Hospital de Pediatría (Children's Hospital) of the Instituto Mexicano del Seguro Social's Centro Médico Nacional de Occidente it is reported a prevalence of overweight of 15.4 % and obesity of 12.2 %, which reflects a nutritional transition.Due to the high prevalence of overweight and obesity in this pediatric hospital of reference, one could conclude that the pediatrician should be able to make a correct evaluation of the nutritional state, because, if he does not detect these problems, we will be condemning children to suffer from a chronic disease for the rest of their lives, and with all the implications in the short, medium and long term.

Explaining Racial Disparities in Obesity Among Men: Does Place Matter?

National data indicate that Black men have higher rates of obesity than White men. Black men also experience earlier onset of many chronic conditions and premature mortality linked to obesity. Explanations for these disparities have been underexplored, and existing national-level studies may be limited in their ability to explicate these long-standing patterns. National data generally do not account for race differences in risk exposures resulting from racial segregation or the confounding between race and socioeconomic status. Therefore, these differences in obesity may be a function of social environment rather than race. This study examined disparities in obesity among Black and White men living in the same social and environmental conditions, who have similar education levels and incomes using data from the Exploring Health Disparities in Integrated Communities-SWB (EHDIC-SWB) study. The findings were compared with the 2003 National Health Interview Survey (NHIS). Logistic regression was used to examine the association between race and obesity adjusting for demographics, socioeconomic status, and health conditions. In the NHIS, Black men had a higher odds of obesity (odds ratio=1.29, 95% confidence interval=1.12-1.49) than White men. However in the EHDIC-SWB, which accounts for social and environmental conditions of where these men live, Black men had similar odds of obesity (odds ratio=1.06, 95% confidence interval=0.70-1.62) compared with White men. These data highlight the importance of the role that setting plays in understanding race disparities in obesity among men. Social environment may be a key determinant of health when seeking to understand race disparities in obesity among Black and White men. © The Author(s) 2014.

The causes and health risks associated with obesity in young people have been extensively documented, but elderly obesity is less well understood, especially in sub-Saharan Africa. This study examines the relationship between obesity and the risk of chronic diseases, cognitive impairment, and functional disability among the elderly in Ghana. It highlights the social and cultural dimensions of elderly obesity and discusses the implications of related health risks using a socio-ecological model. We used data from wave 1 of the Ghana Study on Global Ageing and Adult Health (SAGE) survey-2007/8, with a restricted sample of 2,091 for those 65 years and older. Using random effects multinomial, ordered, and binary logit models, we examined the relationship between obesity and the risk of stage 1 and stage 2 hypertension, arthritis, difficulties with recall and learning new tasks, and deficiencies with activities of daily living and instrumental activities of daily living. Elderly Ghanaians who were overweight and obese had a higher risk of stage 1 and stage 2 hypertension, and were more likely to be diagnosed with arthritis and report severe deficiencies with instrumental activities of daily living. Those who were underweight were 1.71 times more likely to report severe difficulties with activities of daily living. A sub analysis using waist circumference as a measure of body fat showed elderly females with abdominal adiposity were relatively more likely to have stage 2 hypertension. These findings call for urgent policy initiatives geared towards reducing obesity among working adults given the potentially detrimental consequences in late adulthood. Future research should explore the gendered pathways leading to health disadvantages among Ghanaian women in late adulthood.

Diffuse large B-cell lymphoma (DLBCL) in the bypassed stomach after obesity surgery.

Laparoscopic Roux-en-Y gastric bypass is the most commonly performed surgical procedure for obesity and, consequently, post-operative patients are increasingly encountered by all specialties. This is a case of a patient presenting with abdominal pain, nausea and fever 9 months following gastric bypass surgery caused by diffuse large B-cell lymphoma (DLBCL) in the bypassed stomach. It demonstrates well that symptoms that may normally be considered 'red-flags' may not be as obvious or specific following an operation. The case also indicates the importance of considering diagnoses unrelated to surgery presenting in the post-operative period (especially when conventional investigation methods are not feasible), and the potential danger of assuming they are due to the operation alone; had this occurred in this patient then a malignancy may have been missed. This is only the second reported case of DLBCL in the bypassed stomach, and the third for lymphoma of any type. © 2014 The Authors.

Body Mass Index (BMI) offers a simple and reasonable measure of obesity that, with the use of the appropriate reference, can help in the early detection of children with weight problems. Our aim was to compare the two most commonly used international BMI references and the national Greek BMI reference in identifying Greek children being overweight and obese. A group of 1557 children (820 girls and 737 boys, mean age: 11.42 ± 3.51 years) were studied. Weight and height was measured using standard methods, and BMI was calculated. Overweight and obesity were determined using the International Obesity Task Force (IOTF) standards, the Centers for Disease Control and Prevention (CDC) BMI-forage curves and the most recent Greek BMI-for-age curves. RESULTS showed that the IOTF's cut-off limits identifies a significantly higher prevalence of overweight (22.4%) compared with both the CDC's (11.8%, p=0.03) and the Greek's (7.4%, p=0.002) cut-off limits. However, the prevalence of obesity was generally increased when it was determined using the CDC's cut-off limits (13.9%) compared to the prevalence calculated with both the IOTF's (6.5%, p=0.05) and the Greek's (6.9%, n.s.) cut off limits. The use of the national Greek reference standards for BMI underestimates the true prevalence of overweight and obesity. On the contrary, both the IOTF and the CDC standards, although independently, detect an increased number of overweight and obese children and thus they should be adopted in the clinical practice for an earlier identification and a timelier intervention.

Alternative Donor/Unrelated Donor Transplants for the β-Thalassemia and Sickle Cell Disease.

Fitzhugh, Courtney D; Abraham, Allistair; Hsieh, Matthew M

2017-01-01

Considerable progress with respect to donor source has been achieved in allogeneic stem cell transplant for patients with hemoglobin disorders, with matched sibling donors in the 1980s, matched unrelated donors and cord blood sources in the 1990s, and haploidentical donors in the 2000s. Many studies have solidified hematopoietic progenitors from matched sibling marrow, cord blood, or mobilized peripheral blood as the best source-with the lowest graft rejection and graft versus host disease (GvHD), and highest disease-free survival rates. For patients without HLA-matched sibling donors, but who are otherwise eligible for transplant, fully allelic matched unrelated donor (8/8 HLA-A, B, C, DRB1) appears to be the next best option, though an ongoing study in patients with sickle cell disease will provide data that are currently lacking. There are high GvHD rates and low engraftment rates in some of the unrelated cord transplant studies. Haploidentical donors have emerged in the last decade to have less GvHD; however, improvements are needed to increase the engraftment rate. Thus the decision to use unrelated cord blood units or haploidentical donors may depend on the institutional expertise; there is no clear preferred choice over the other. Active research is ongoing in expanding cord blood progenitor cells to overcome the limitation of cell dose, including the options of small molecule inhibitor compounds added to ex vivo culture or co-culture with supportive cell lines. There are inconsistent data from using 7/8 or lower matched unrelated donors. Before routine use of these less matched donor sources, work is needed to improve patient selection, conditioning regimen, GvHD prophylaxis, and/or other strategies.

Origins of Balance Disorders during a Daily Living Movement in Obese: Can Biomechanical Factors Explain Everything?

Obese people suffer from postural deficits and are more subject to falls than their lean counterpart. To improve prevention and post-fall rehabilitation programs, it seems important to better understand the posturo-kinetic disorders in daily life situations by determining the contribution of some key factors, mainly morphological characteristics and physical activity level, in the apparition of these disorders. Twelve severe android obese and eight healthy non obese adults performed a reaching task mobilizing the whole body. To further determine the origin of the postural and motor behavior differences, non obese individuals also performed an experimental session with additional constraints which simulated some of the obese morphological characteristics. Impact of the sedentary lifestyle was also studied by dissociation of the obese in two subgroups: physically « active » and physically « inactive ». Movement kinetics and kinematics were characterized with an optoelectronic system synchronized to a force platform. The mechanical equilibrium pattern was evaluated through the displacements of the Centre of Mass (CoM) and the centre of foot pressure within the Base of Support (BoS). Results showed that obesity decreased movement speed (≈−23%, p<0.01), strongly increased CoM displacement (≈+30%, p<0.05) and induced an important spatio-temporal desynchronization (≈+40%, p<0.05) of the focal and postural components of the movement during the transition between the descending and ascending movements. The role of some morphological characteristics and of physical activity on obese patients' postural control disorder is discussed and set back in the more general context of overall factors contributing to postural deficits with obesity.

Underserved minority populations in the US Affiliated Pacific Islands (USAPI), Hawaii, and Alaska display disproportionate rates of childhood obesity. The region's unique circumstance should be taken into account when designing obesity prevention interventions. The purpose of this paper is to (a), describe the community engagement process (CEP) used by the Children's Healthy Living (CHL) Program for remote underserved minority populations in the USAPI, Hawaii, and Alaska (b) report community-identified priorities for an environmental intervention addressing early childhood (ages 2-8 years) obesity, and (c) share lessons learned in the CEP. Four communities in each of five CHL jurisdictions (Alaska, American Samoa, Commonwealth of the Northern Mariana Islands, Guam, Hawai'i) were selected to participate in the community-randomized matched-pair trial. Over 900 community members including parents, teachers, and community leaders participated in the CEP over a 14 month period. The CEP was used to identify environmental intervention priorities to address six behavioral outcomes: increasing fruit/vegetable consumption, water intake, physical activity and sleep; and decreasing screen time and intake of sugar sweetened beverages. Community members were engaged through Local Advisory Committees, key informant interviews and participatory community meetings. Community-identified priorities centered on policy development; role modeling; enhancing access to healthy food, clean water, and physical activity venues; and healthy living education. Through the CEP, CHL identified culturally appropriate priorities for intervention that were also consistent with the literature on effective obesity prevention practices. Results of the CEP will guide the CHL intervention design and implementation. The CHL CEP may serve as a model for other underserved minority island populations.

The prevalence of cardiovascular risk factors is increasing in aboriginal populations in Chile. To study the prevalence of obesity, type 2 diabetes and serum lipids in two aboriginal populations, Mapuche and Aymara, that were transferred from a rural to a urban environment. Two groups of subjects over 20 years were analyzed, Mapuche and Aymara. The Mapuche group was formed by 42 men and 105 women, living in four urban communities of Santiago, and an Aymara group formed by 42 men and 118 women, living in Arica, in Northern Chile. Anthropometric measurements, blood pressure, lipid profile, oral glucose tolerance test, fasting insulin and serum leptin were determined. The prevalence of type 2 diabetes was 6.9% in Aymara and 8.2% in Mapuche subjects. The frequency of glucose intolerance was similar in both groups, but greater among men. A total blood cholesterol over 200 mg/dl was observed in 43.1% of Aymara and 27.9% of Mapuche subjects (p <0.008). Serum triglycerides over 150 mg/dl were observed in 16.9 and 23.1% of Aymara and Mapuche individuals, respectively (p= NS). The prevalence of type 2 diabetes and dyslipidemia in turban aboriginal populations is higher than that of their rural counterparts. A possible explanation for these results are changes in lifestyles that come along with urbanization, characterized by a high consumption of saturated fat and refined sugars and a low level of physical activity.

Passive smoke exposure (PSE) may be a risk factor for childhood overweight and obesity and is associated with worse neurocognitive development, cognition, and sleep in children. The purpose of the study is to examine the effects of PSE on adiposity, cognition, and sleep in overweight and obese children using an objective measure of PSE. Overweight or obese children (n = 222) aged 7-11 (9.4 ± 1.1 years; 58% black; 58% female; 85% obese) were recruited from schools near Augusta, Georgia, over the course of the school year from 2003-2006 for a clinical trial, with data analyzed in 2009-2010. Passive smoke exposure was measured with plasma cotinine. Health, cognitive, and sleep measures and parent report of smoke exposure were obtained. Overweight and obese children with PSE had greater overall and central adiposity than nonexposed overweight and obese children (p < 0.03). However, PSE was unrelated to prediabetes, insulin resistance, or visceral fat. PSE was linked to poorer cognitive scores (p < 0.04) independent of adiposity, but was not related to sleep-disordered breathing. PSE is associated with fatness and poorer cognition in children. Tailored interventions that target multiple health risk factors including nutrition, physical activity, and tobacco use in children and families are needed to prevent adverse health outcomes related to tobacco use and obesity.

Abstract Background: “Living High-Training Low” (LHTL) is effective for the improvement of athletic ability; however, little is known about the effect of LHTL on obese individuals. The present study determined whether LHTL would have favorable influence on body composition, rebalance the appetite hormones, and explore the underlying mechanism. Methods: Adolescents with obesity [body mass index (BMI) >30 kg/m2] were randomly assigned to “Living Low-Training Low” (LLTL, n = 19) group that slept in a normobaric normoxia condition and the LHTL (n = 16) group slept in a normobaric hypoxia room (14.7% PO2 ∼2700 m). Both groups underwent the same aerobic exercise training program. Morphological, blood lipids, and appetite hormones were measured and assessed. Results: After the intervention, the body composition improved in both groups, whereas reductions in body weight (BW), BMI, and lean body mass increased significantly in the LHTL group (all, P < .05). In the LLTL group, cholecystokinin (CCK) decreased remarkably (P < .05) and CCK changes were positively associated with changes in BW (r = 0.585, P = .011) and BMI (r = 0.587, P = .010). However, in the LHTL group, changes in plasma glucagon-like peptide-1 (GLP-1) and interleukin-6 (IL-6) levels, positively correlated with each other (r = 0.708, P = .015) but negatively with BW changes (r = −0.608, P = .027 and r = −0.518, P = .048, respectively). Conclusion: The results indicated that LHTL could induce more weight loss safely and efficiently as compared to LLTL and increase the plasma GLP-1 levels that may be mediated by IL-6 to rebalance the appetite. Thus, an efficient method to treat obesity and prevent weight regain by appetite rebalance in hypoxia condition was established. PMID:29465583

Satiety mechanisms in genetic risk of obesity.

A better understanding of the cause of obesity is a clinical priority. Obesity is highly heritable, and specific genes are being identified. Discovering the mechanisms through which obesity-related genes influence weight would help pinpoint novel targets for intervention. One potential mechanism is satiety responsiveness. Lack of satiety characterizes many monogenic obesity disorders, and lower satiety responsiveness is linked with weight gain in population samples. To test the hypothesis that satiety responsiveness is an intermediate behavioral phenotype associated with genetic predisposition to obesity in children. Cross-sectional observational study of a population-based cohort of twins born January 1, 1994, to December 31, 1996 (Twins Early Development Study). Participants included 2258 unrelated children (53.3% female; mean [SD] age, 9.9 [0.8] years), one randomly selected from each twin pair. Genetic predisposition to obesity. We created a polygenic risk score (PRS) comprising 28 common obesity-related single-nucleotide polymorphisms identified in a meta-analysis of obesity-related genome-wide association studies. Satiety responsiveness was indexed with a standard psychometric scale (Child Eating Behavior Questionnaire). Using 1990 United Kingdom reference data, body mass index SD scores and waist SD scores were calculated from parent-reported anthropometric data for each child. Information on satiety responsiveness, anthropometrics, and genotype was available for 2258 children. We examined associations among the PRS, adiposity, and satiety responsiveness. The PRS was negatively related to satiety responsiveness (β coefficient, -0.060; 95% CI, -0.019 to -0.101) and positively related to adiposity (β coefficient, 0.177; 95% CI, 0.136-0.218 for body mass index SD scores and β coefficient, 0.167; 95% CI, 0.126-0.208 for waist SD scores). More children in the top 25% of the PRS were overweight than in the lowest 25% (18.5% vs 7.2%; odds ratio, 2.90; 95% CI, 1

There are few data regarding the prevalence of obesity and its socioeconomic determinants among elderly individuals, particularly in Iran. We wished to determine the prevalence of overweight and obesity in free-living elderly people and the relationship to nutritional and socioeconomic factors in the Razavi-Khorasan province of Iran. Free-living elderly persons (917 males/1045 females), aged > or =60 years, were recruited using cluster sampling. Overweight and obesity were evaluated using body mass index (BMI) and subjects were categorized as thin (BMI <18.5 kg/m2), normal (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), and obese (> or =30 kg/m2). The association between the prevalence of overweight or obesity with socioeconomic and demographic factors, including gender, place of residence, literacy, type of living, source of income, use of supplements during the past 3 months, and employment status, was examined using regression analysis. The distribution of BMI values indicated that 13, 46.5, 28.9, and 11.7% of the total population were thin, normal, overweight, and obese, respectively. The prevalence of central obesity was higher among Iranian women than men (63.1 vs. 18.6%, respectively). Regression analysis results indicated that gender (p < 0.001), place of residence (p < 0.001), literacy (p = 0.01), and source of income (p < 0.001) were significantly associated with the incidence of overweight or obesity. This study showed that 40.6% of elderly subjects were overweight or obese. Results reinforce the need to plan strategies for primary prevention of this fast-growing public health problem.

Obesity and Sexuality Among Older Couples.

We investigate whether obesity is associated with sexual activity, sexual frequency, and the range of sexual behaviors in heterosexual older couples. We assess to what extent associations between obesity and sexuality are explained by physical, psychological, and sexual health, and by relationship quality. We use data from 1,698 older adults in 849 partnered dyads in the 2010-2011 wave of the National Social Life, Health, and Aging Project and conduct couple-level analysis featuring women's and men's characteristics. Women's obesity-particularly at severe levels-is negatively associated with coupled sexual activity, and that the association is not mediated by hypothesized mediators. Men's obesity did not have any association with sexual activity. There was no significant difference between overweight and normal weight adults across all three sexuality measures. The growing number of older adults with high levels of body mass index, particularly women, may face certain difficulties in maintaining active sexual lives.

Introduction Obesity is a chronic, complex, and multifactorial disease, characterized by excess body fat. Diverse studies of the human genome have led to the identification of susceptibility genes that contribute to obesity. However, relatively few studies have addressed specifically the association between the level of expression of these genes and obesity. Material and methods We studied 160 healthy and obese unrelated Mexican children aged 6 to 14 years. We measured the transcriptional expression of 20 genes associated with obesity, in addition to the biochemical parameters, in peripheral white blood cells. The detection of mRNA levels was performed using the OpenArray Real-Time PCR System (Applied Biosystems). Results Obese children exhibited higher values of fasting glucose (p = 0.034), fasting insulin (p = 0.004), low-density lipoprotein (p = 0.006), triglycerides (p < 0.001), systolic blood pressure and diastolic blood pressure (p < 0.001), and lower values of high-density lipoprotein (p < 0.001) compared to lean children. Analysis of transcriptional expression data showed a difference for ADRB1 (p = 0.0297), ADIPOR1 (p = 0.0317), GHRL (p = 0.0060) and FTO (p = 0.0348) genes. Conclusions Our results suggest that changes in the expression level of the studied genes are involved in biological processes implicated in the development of childhood obesity. Our study contributes new perspectives for a better understanding of biological processes involved in obesity. The protocol was approved by the National Committee and Ethical Committee Board from the Mexican Social Security Institute (IMSS) (IMSS FIS/IMSS/PRIO/10/011). PMID:27695486

Swedish school children living in rural areas and in areas with low education are at excess risk of becoming overweight. This study examines influences of societal and individual characteristics (children and their parents) on prevalence of overweight and obesity, in a national sample of 7-9-year-old children. Anthropometric and lifestyle data were collected in a nationally representative sample of 3636 Swedish children. Overweight and obesity (International Obesity Task Force (IOTF)) data were analyzed in relation to lifestyle factors, parental weight, education and breast-feeding. The prevalence of overweight was 15.6% including 2.6% obese. Urbanization level and parental characteristics (weight status and education) were related to risk of overweight. Overall less favorable lifestyle characteristics were observed in rural areas and for children of low/medium educated mothers. Boys had greater risk of obesity in semi-urban and rural areas but this was not true for girls. For children's overweight, the living area effect was attenuated in multivariate analysis, while there was an association with origin of parents, high parental weight and medium maternal education. For obesity, the living area effect remained in boys while having two non-Nordic parents predicted obesity in girls. Parental weight status was associated with obesity in both girls and boys. Individual and societal factors influence children's weight status, and parental weight status is a strong determinant. Including overweight and obese parents in future health promoting interventions could be a strategy to prevent children from becoming overweight, but identifying those parents may prove difficult. To ensure reaching children with the greatest needs, targeting high risk areas might be a more effective approach.

To test how genomic loci identified in genome-wide association studies influence the development of obesity. A 38-year prospective longitudinal study of a representative birth cohort. The Dunedin Multidisciplinary Health and Development Study, Dunedin, New Zealand. One thousand thirty-seven male and female study members. We assessed genetic risk with a multilocus genetic risk score. The genetic risk score was composed of single-nucleotide polymorphisms identified in genome-wide association studies of obesity-related phenotypes. We assessed family history from parent body mass index data collected when study members were 11 years of age. Body mass index growth curves, developmental phenotypes of obesity, and adult obesity outcomes were defined from anthropometric assessments at birth and at 12 subsequent in-person interviews through 38 years of age. Individuals with higher genetic risk scores were more likely to be chronically obese in adulthood. Genetic risk first manifested as rapid growth during early childhood. Genetic risk was unrelated to birth weight. After birth, children at higher genetic risk gained weight more rapidly and reached adiposity rebound earlier and at a higher body mass index. In turn, these developmental phenotypes predicted adult obesity, mediating about half the genetic effect on adult obesity risk. Genetic associations with growth and obesity risk were independent of family history, indicating that the genetic risk score could provide novel information to clinicians. Genetic variation linked with obesity risk operates, in part, through accelerating growth in the early childhood years after birth. Etiological research and prevention strategies should target early childhood to address the obesity epidemic.

Cardiovascular disease (CVD) is a major global health problem and the leading cause of death in Europe. Risk factors such as obesity and hypertension that accelerate the development of CVD begin in childhood. Ethnicity is a known risk factor for CVD in adults. The aim of this study is to explore differences in the prevalence of hypertension and dyslipidemia among overweight/obese and normal-weight children/adolescents of three different ethnic origins living in Central Europe. Prevalence of hypertension and dyslipidemia was calculated among obese/overweight children/adolescents (n = 25,986; mean age 12.7 ± 3.0 years; range: 0-18 years; 46% males) documented in the German-Austrian-Swiss APV (Prospective Documentation of Overweight Children and Adolescents) registry and among normal-weight subjects (n = 14,935; mean age: 8.8 ± 5.1 years; range 0-18 years; 51% males) from the population-based cross-sectional German Health Interview and Examination Survey for Children and Adolescents (KiGGS) study. In both cohorts, subjects were categorized into three ethnic groups (Central European: Germany, Austria, Switzerland; Southeastern European: Turkish; Southern European: Spain, Portugal, Italy, Greece, Cyprus, Malta) based on the country of birth of both parents. Regression models were used to examine ethnic differences after adjustment for age and gender and body mass index (BMI) category. Age-, gender- and BMI category-adjusted prevalence of hypertension were 38% and 39% for the ethnic minority groups, compared with 35% among German/Austrian/Swiss counterparts. Turkish ethnicity was significantly associated with hypertension (odds ratio (OR) 1.14; 95% confidence interval: 1.02-1.27; P = 0.0446). No significant ethnic differences were found in lipid levels. Prevalence of hypertension found among normal-weight subjects (Central European vs Southeastern vs Southern European: 6.8% vs 6.3% vs 7.2%) did not differ significantly.

Obesity, which has become an increasing problem worldwide, poses a risk for kidney transplant recipients both before and after surgery. In this literature review, we studied the effects of obesity before and after kidney transplant. There are numerous studies and different opinions on the effects of obesity on graft function before and after transplant. Obesity prolongs surgery time and the ischemic process. A large cohort study of 11 836 recipients noted a close association between body mass index and delayed renal transplant and delayed graft function. However, another study found that being overweight or obese before transplant did not have any effects over the medium and long term. A 20-year follow-up study indicated that the firstyear body mass index in recipients after renal transplant had a greater effect on graft function and survival than body mass index before transplant. Still, another study found that body mass index had no effects on graft function and survival. In the study, 3-year graft function and mortality rates of morbidly obese people without diabetes, the functional status without dialysis, and living-donor transplant were reported to be much lower than in those with normal weight. In conclusion, there is no consensus on the effects of obesity before and after transplant, and it has been pointed out that more research should be done on this subject.

Health-equity issues related to childhood obesity: a scoping review.

2017-06-01

The purpose of this scoping review was to determine the health-equity issues that relate to childhood obesity. Health-equity issues related to childhood obesity were identified by analyzing food environment, natural and built environment, and social environment. The authors searched Medline, PubMed, and Web of Science, using the keywords "children" and "obesity." Specific terms for each environment were added: "food desert," "advertising," "insecurity," "price," "processing," "trade," and "school" for food environment; "urban design," "land use," "transportation mode," "public facilities," and "market access" for natural and built environment; and "financial capacity/poverty," "living conditions," "transport access," "remoteness," "social support," "social cohesion," "working practices," "eating habits," "time," and "social norms" for social environment. Inclusion criteria were studies or reports with populations under age 12, conducted in the United States, and published in English in 2005 or later. The final search yielded 39 references (16 for food environment, 11 for built environment, and 12 for social environment). Most food-environment elements were associated with obesity, except food insecurity and food deserts. A natural and built environment that hinders access to physical activity resources and access to healthy foods increased the risk of childhood obesity. Similarly, a negative social environment was associated with childhood obesity. More research is needed on the effects of food production, living conditions, time for shopping, and exercise, as related to childhood obesity. Most elements of food, natural and built, and social-environments were associated with weight in children under age 12, except food insecurity and food deserts. © 2017 American Association of Public Health Dentistry.

Friends and family: A software program for identification of unrelated individuals from molecular marker data.

The identification of related and unrelated individuals from molecular marker data is often difficult, particularly when no pedigree information is available and the data set is large. High levels of relatedness or inbreeding can influence genotype frequencies and thus genetic marker evaluation, as well as the accurate inference of hidden genetic structure. Identification of related and unrelated individuals is also important in breeding programmes, to inform decisions about breeding pairs and translocations. We present Friends and Family, a Windows executable program with a graphical user interface that identifies unrelated individuals from a pairwise relatedness matrix or table generated in programs such as coancestry and genalex. Friends and Family outputs a list of samples that are all unrelated to each other, based on a user-defined relatedness cut-off value. This unrelated data set can be used in downstream analyses, such as marker evaluation or inference of genetic structure. The results can be compared to that of the full data set to determine the effect related individuals have on the analyses. We demonstrate one of the applications of the program: how the removal of related individuals altered the Hardy-Weinberg equilibrium test outcome for microsatellite markers in an empirical data set.

Obesity causes substantial morbidity and mortality in the United States. Evidence shows that primary care physician (PCP) supply correlates positively with improved health, but its association with obesity in the United States as not been adequately characterized. Our purpose was to characterize the association between PCP supply in US counties and adult obesity. We performed a multivariate logistic regression analysis to examine the relationship between county-level PCP supply and individual obesity status. We controlled for individual variables, including sex, race, marital status, income, and insurance status, and county-level variables, including rurality and poverty. Higher county-level PCP supply was associated with lower adult obesity after controlling for common confounders. Individuals living in counties with the most robust PCP supply were about 20% less likely to be obese (P ≤ .01) than those living in counties with the lowest PCP supply. While the observed association between the supply of PCPs and lower rates of obesity may not be causal, the association warrants further investigation. This may have important implications for restructuring the physician workforce in the context of the current PCP shortage and implementation of the Affordable Care Act and the patient-centered medical home. © Copyright 2016 by the American Board of Family Medicine.

The Effects of Physically Unrelated Near Neighbors on the Weak Galaxy-Galaxy Lensing Signal

NASA Astrophysics Data System (ADS)

Brainerd, Tereasa

2018-01-01

The effects of physically unrelated near neighbors on the weak galaxy-galaxy lensing signal are explored. Physically unrelated near neighbors are galaxies that are close to a given lens galaxy in projection on the sky, but are located at substantially different redshifts. Typically, the effects of such physically unrelated near neighbors are assumed to cancel. If that were truly the case, these objects would not contribute to the mean tangential shear around the lenses and they can be ignored when using an observed weak lensing signal to infer the excess surface mass density surrounding a set of lens galaxies. Here, observed galaxies with known redshifts and luminosities are used as the basis of a suite of Monte Carlo simluations of weak galaxy-galaxy lensing. The simulations incorporate the intrinsic clustering of the lens galaxies, as well as the intrinsic distribution of the lens galaxy masses. Dark matter halos of appropriate sizes and masses are assigned to each of the lens galaxies, and the net effect of all lenses on a set of background source galaxies is determined. The net weak lensing signal (i.e., the mean tangential shear due to all lenses along the line of sight) is computed and then compared to the excess surface mass density surrounding the lenses. Due to the broad redshift and mass distributions of the lenses, the effects of physically unrelated near neighbors in the simulations do not cancel. On scales equal to or greater than the scale for which the two-halo term contributes substantially to the shear, this non-cancellation of the effects of physically unrelated near neighbors significantly affects the accuracy with which the excess surface mass density may be inferred from the mean tangential shear via the standard formula: < ΔΣ > = < Σc γt > . The effects of physically unrelated near neighbors are greatest for the least massive lens galaxies but can also be important for the most massive lens galaxies.

[Clinical impact of HLA disparities in transplants from unrelated donors].

The search for an unrelated donor must be based on the HLA typing of the donor and the host. PCR techniques have facilitated high-resolution HLA typing, but they have also elicited questions about the real impact of the various disparities on the progress of the graft Thus, whereas a donor used to be accepted based on HLA-A and B Identity determined by serology and HLA-DRB1 through molecular biology techniques, now a donor is required to have a 70/70 Identity for loci HLA-A, B, C, DRB7, and DQB7. Furthermore, the real effect of the disparities in the sixth locus of the major histocompatibility complex-HLA-DPBT-is still in doubt. This study intends to conduct a literature review of the clinical impact of the various HLA disparities In transplants from unrelated donors.

Although peripheral blood stem cells (PBSCs) have replaced bone marrow (BM) as the most common unrelated donor progenitor cell product collected, a direct comparison of concurrent PBSC versus BM donation experiences has not been performed. We report a prospective study of 2726 BM and 6768 PBSC donors who underwent collection from 2004 to 2009. Pain and toxicities were assessed at baseline, during G-CSF administration, on the day of collection, within 48 hours of donation, and weekly until full recovery. Peak levels of pain and toxicities did not differ between the 2 donation processes for most donors. Among obese donors, PBSC donors were at increased risk of grade 2 to 4 pain as well as grade 2 to 4 toxicities during the pericollection period. In contrast, BM donors were more likely to experience grade 2 to 4 toxicities at 1 week and pain at 1 week and 1 month after the procedure. BM donors experienced slower recovery, with 3% still not fully recovered at 24 weeks, whereas 100% of PBSC donors had recovered. Other factors associated with toxicity included obesity, increasing age, and female sex. In summary, this study provides extensive detail regarding individualized risk patterns of PBSC versus BM donation toxicity, suggesting donor profiles that can be targeted with interventions to minimize toxicity.

Relationship between obesity, negative affect and basal heart rate in predicting heart rate reactivity to psychological stress among adolescents.

Park, Andres E; Huynh, Pauline; Schell, Anne M; Baker, Laura A

Reduced cardiovascular responses to psychological stressors have been found to be associated with both obesity and negative affect in adults, but have been less well studied in children and adolescent populations. These findings have most often been interpreted as reflecting reduced sympathetic nervous system response, perhaps associated with heightened baseline sympathetic activation among the obese and those manifesting negative affect. However, obesity and negative affect may themselves be correlated, raising the question of whether they both independently affect cardiovascular reactivity. The present study thus examined the separate effects of obesity and negative affect on both cardiovascular and skin conductance responses to stress (e.g., during a serial subtraction math task) in adolescents, while controlling for baseline levels of autonomic activity during rest. Both obesity and negative affect had independent and negative associations with cardiovascular reactivity, such that reduced stress responses were apparent for obese adolescents and those with high levels of negative affect. In contrast, neither obesity nor negative affect was related to skin conductance responses to stress, implicating specifically noradrenergic mechanisms rather than sympathetic mechanisms generally as being deficient. Moreover, baseline heart rate was unrelated to obesity in this sample, which suggests that heightened baseline of sympathetic activity is not necessary for the reduced cardiovascular reactivity to stress.

Obesity and cardiovascular disease: friend or foe?

Kim, Seong Hwan; Després, Jean-Pierre; Koh, Kwang Kon

2016-12-21

Obesity is currently one of the greatest public health issues worldwide. However, despite its known deleterious effects on the cardiovascular system and its association with numerous cardiovascular diseases (CVD), recent findings leading to the development of concepts such as metabolically healthy obesity, the obesity paradox, and protective subcutaneous fat depots have raised a lively debate on the disparate effects of obesity on health outcomes. Regarding the concept of metabolically healthy obesity, by presumably labelling a subset of obese people as metabolically healthy, physicians may not feel pressed to curb the current obesity epidemic and prevent the next generation of people from becoming obese. Another issue is that the most commonly used anthropometric index to define obesity, the body mass index, is at the core of the controversy because of its limitations including its inability to discriminate between fat mass and muscle mass. Many recent epidemiological and metabolic studies have used other indices such as waist-hip ratio, waist circumference, and imaging (computed tomography or magnetic resonance imaging) measurements of visceral adiposity and of ectopic fat depots. In addition, emerging evidence supports the importance of cardiorespiratory fitness, skeletal muscle mass and strength in patients with obesity as useful variables to predict CVD risk beyond adiposity. In this review, we will discuss the complex and disparate effects of obesity on CVD, particularly focusing on whether, under given circumstances, it could be harmful, potentially harmless or neutral, or even possibly protective.

Research contributions on childhood obesity from a public-private partnership

PubMed Central

2015-01-01

Background Childhood obesity remains a significant global problem with immediate and long-term individual health and societal consequences. Targets for change should include the most potent and predictive factors for obesity at all levels of the personal, social and physical environments. The Michael & Susan Dell Center for Healthy Living (‘the Center’) is a public-private partnership that was developed to address child health issues through research, service, and education. This overview paper introduces a special issue of seven articles on childhood obesity from the Center, and the implications of this research for obesity prevention. Methods and results A review of the literature on public-private partnerships was undertaken and key components of the partnership between the Michael & Susan Dell Foundation and the Center were compared for compatibility. The conceptual framework for Center research, based on social cognitive theory and the social-ecological model, is explained. An overview of papers in this special issue, relative to the conceptual framework, and the implications of this research for childhood obesity prevention, are provided. Conclusions The public-private partnership that created the Michael & Susan Dell Center for Healthy Living has been instrumental in motivating the Center’s academic faculty to focus their research on improvements in child, family and community health through etiologic, epidemiologic, methodologic and intervention research. This special issue extends this work and places particular emphasis on socioeconomic inequalities in addressing the obesity problem in the U.S. and worldwide. PMID:26222489

Background/Objectives In animal studies, exposure to multi-vitamins may be associated with obesity in the offspring; however, data in humans is sparse. We therefore examined the association between prenatal vitamin intake during pregnancy and offspring obesity. Subjects/Methods We investigated the association between prenatal vitamin intake and obesity among 29 160 mother-daughter dyads in the Nurses’ Health Study II. Mothers of participants provided information on prenatal vitamin use during pregnancy with the nurse daughter. Information on body fatness at ages 5 and 10, body mass index (BMI) at age 18, weight in 1989 and 2009, waist circumference, and height was obtained from the daughter. Polytomous logistic regression was used to predict BMI in early adulthood and adulthood, and body fatness in childhood. Linear regression was used to predict waist circumference in adulthood. Results In utero exposure to prenatal vitamins was not associated with body fatness, either in childhood or adulthood. Women whose mothers took prenatal vitamins during pregnancy had a covariate-adjusted odds ratio of being obese in adulthood of 0.99 (95% CI 0.92 – 1.05, P-value = 0.68) compared to women whose mothers did not take prenatal vitamins. Women whose mothers took prenatal vitamins during pregnancy had a covariate-adjusted odds ratio of having the largest body shape at age 5 of 1.02 (95% CI 0.90 – 1.15, P-value = 0.78). In additional analyses, in utero exposure to prenatal vitamins was also unrelated to adult abdominal adiposity. Conclusions Exposure to prenatal vitamins was not associated with body fatness either in childhood or in adulthood. PMID:24942869

ENSANUT 2012 showed a combined prevalence of overweight and obesity of 34.4% in Mexican children. Single nucleotide polymorphisms (SNPs) of the ADIPOQ and ADIPOR2 genes have been reported in many populations, but their association with obesity has not been confirmed in other studies. Our aim was to determine the association of SNPs from ADIPOQ and ADIPOR2 genes with obesity in Mexican children. A total of 2,634 children from 6 to 12 years old were enrolled in the study from four IMSS Units in Mexico City. We selected 1,469 unrelated children (745 normal weight and 724 overweight/obese). Phenotype characterization included anthropometric measurements, blood pressure, biochemical parameters, insulin concentrations and presence of acanthosis nigricans (AN). Analysis of the SNPs rs182052, rs266729, rs2241766, rs822393 of ADIPOQ and rs11061971 of ADIPOR2 was carried out in the DNA samples. The study showed significant differences (p <0.05) between groups in waist circumference, blood pressure, presence of AN, insulin concentrations, HOMA-IR, fasting glucose and lipid parameters, being higher in obese children. No associations in ADIPOQ variants with the presence of overweight/obesity were found. The presence of the variant rs11061971 of ADIPOR2 in children had a significant association with protection of overweight/obesity (OR 0.79, 95% CI 0.68-0.93, p = 0.003). Also, the log-additive model confirmed the association by codominant and dominant models (p <0.05). The presence of rs11061971 of ADIPOR2 variant confers protection against obesity and could be used as a marker in Mexican children. Copyright © 2014 Hospital Infantil de México Federico Gómez.

To evaluate the association between men's body mass index (BMI), early embryo quality, and clinical outcomes in couples undergoing in vitro fertilization (IVF). Prospective cohort study. Fertility clinic in an academic medical center. 114 couples who underwent 172 assisted reproduction cycles. None. Fertilization rate, embryo quality, implantation rate, clinical pregnancy rate, and live birth rate. The fertilization rate was higher among obese men than among normal weight men in conventional IVF cycles. No statistically significant associations were found between men's BMI and the proportion of poor-quality embryos on day 3, slow embryo cleavage rate, or accelerated embryo cleavage rate. Men's BMI was unrelated to positive β-human chorionic gonadotropin rate, clinical pregnancy rate, or live-birth rate per embryo transfer. Among couples undergoing intracytoplasmic sperm injection, the odds of live birth in couples with obese male partners was 84% lower than the odds in couples with men with normal BMI. Our data suggest a possible deleterious effect of male obesity on the odds of having a live birth among couples undergoing intracytoplasmic sperm injection.

Background Allografts from living donors survive longer than those from deceased donors but the role of HLA mismatching in living kidney donation is still in question. We examined the effect of HLA compatibility on kidney allograft survival from living donors by studying all first adult kidney transplants performed in the United States over 25 years. Methods Using the United Network for Organ Sharing data, we identified first kidney transplants between October 1, 1987, and December 31, 2013. Recipients were classified by their number of HLA mismatches and stratified by donor origin. Cox multivariate regression analyses adjusting for recipient and donor transplant characteristics were performed to determine impact of HLA compatibility on kidney allograft survival for all living donors and for living related and living unrelated subsets. Results There were 66 596 first adult transplants from living donors with 348 960 years of follow-up. We found a linear relationship between HLA mismatch and allograft survival. In adjusted analyses, among all living donors, 1 mismatch conferred a 44% higher risk, whereas 6 mismatches conferred a twofold higher risk of allograft failure. When using 0-mismatched full siblings as a reference, living-donor kidneys reduce the hazard of failure by approximately 34% when compared with deceased donors. Twenty-five years of transplant experience, stratified by donor source, was summarized and presented as a guide for allocation. Conclusions These data reinforce the importance of optimizing HLA matching to further improve survival in first adult kidney allografts in the future, especially in living unrelated donations, when possible.

We investigated the differences in the meal patterns of normal weight vs. overweight/obese individuals occurring at home vs. other locations. The location of meals and their size in free-living participants were continuously recorded for 7 consecutive days. Study 1: 81 males and 84 females recorded their intake in 7-d diet diaries and wore a belt that contained a GPS Logger to record their location continuously for 7 consecutive days. Study 2: 388 males and 621 females recorded their intake in diet diaries for 7 consecutive days. In both studies, compared to eating at home, overweight/obese participants ate larger meals away from home in both restaurants and other locations than normal weight participants. Overweight/obese individuals appear to be more responsive to environmental cues for eating away from home. This suggests that the influence of the built environment on the intake of overweight/obese individuals may contribute to the obesity epidemic. PMID:22565154

Gestures are an important part of interpersonal communication, for example by illustrating physical properties of speech contents (e.g., "the ball is round"). The meaning of these so-called iconic gestures is strongly intertwined with speech. We investigated the neural correlates of the semantic integration for verbal and gestural information. Participants watched short videos of five speech and gesture conditions performed by an actor, including variation of language (familiar German vs. unfamiliar Russian), variation of gesture (iconic vs. unrelated), as well as isolated familiar language, while brain activation was measured using functional magnetic resonance imaging. For familiar speech with either of both gesture types contrasted to Russian speech-gesture pairs, activation increases were observed at the left temporo-occipital junction. Apart from this shared location, speech with iconic gestures exclusively engaged left occipital areas, whereas speech with unrelated gestures activated bilateral parietal and posterior temporal regions. Our results demonstrate that the processing of speech with speech-related versus speech-unrelated gestures occurs in two distinct but partly overlapping networks. The distinct processing streams (visual versus linguistic/spatial) are interpreted in terms of "auxiliary systems" allowing the integration of speech and gesture in the left temporo-occipital region.

2017-04-01

Maternal obesity has been shown to affect reproductive function and pregnancy outcomes following in vitro fertilization. More recently, studies have demonstrated lower live birth rates after single blastocyst transfer (SBT) in patients who are overweight or obese. However, the impact of morbid obesity on pregnancy outcomes after SBT has not been well elucidated. The present study aimed to determine whether morbid obesity has a detrimental impact on pregnancy outcomes after SBT in a North American population. A retrospective, cohort study including 520 nulliparous and multiparous women undergoing top-quality SBT between August 2010 and March 2014 at a University Health Centre in North America was conducted. Primary outcomes included: miscarriage rate, clinical pregnancy rate, and live birth rate. Subjects were divided into different BMI categories (kg/m 2 ), including <20, 20-24.9, 25.0-29.9, 30-40, and 40 or more. The miscarriage rate per pregnancy for each group, respectively, was 36, 64, 59, 61, and 50% (p = 0.16); the clinical pregnancy (per patient) rate per group was 36, 52, 38, 26, and 10% (p = 0.009); and the live birth rate (per patient) per group was 35, 50, 38, 26 and 10% (p = 0.03). Morbid obesity is a strong and independent predictor of poor pregnancy outcomes in patients undergoing top-quality SBT.

Weather adjustment using seemingly unrelated regression

Seemingly unrelated regression (SUR) is a system estimation technique that accounts for time-contemporaneous correlation between individual equations within a system of equations. SUR is suited to weather adjustment estimations when the estimation is: (1) composed of a system of equations and (2) the system of equations represents either different weather stations, different sales sectors or a combination of different weather stations and different sales sectors. SUR utilizes the cross-equation error values to develop more accurate estimates of the system coefficients than are obtained using ordinary least-squares (OLS) estimation. SUR estimates can be generated using a variety of statistical software packagesmore » including MicroTSP and SAS.« less

To evaluate the maternal perception of their child's weight (MPCW) and perception of unrelated children's weight. Cross-sectional. Maternal and Child Nursing Health Department at 6 Units of Family Medicine. 486 dyads (mother and child under 1 year). The following question was applied: "I think my child is", and images were provided according the child's gender. Children's weight and height were measured. A total of 20.5% of the mothers of overweight (OW) children accurately perceived this situation, while none of the mothers of obese (OB) children did (κ=0.14±0.03, Z=5.36, p=.001). By images, 63.3% of mothers of OW children and 33.3% of mothers of OB children perceived this situation (κ=0.01±0.02, Z=0.73, p=.46). Most mothers selected the image of OW child as the image of a healthy child (κ=-0.04±0.01, Z=-2.65, p=.008), the image of a child under 1 year (κ=-0.01±0.02, Z=-0.86, p=.38) and the image that they would like their child to look like (κ=0.0004±0.01, Z=0.02, p=.98). The mothers do not perceive the OW-OB of their children. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

Public health campaigns and obesity - a critique.

Controlling obesity has become one of the highest priorities for public health practitioners in developed countries. In the absence of safe, effective and widely accessible high-risk approaches (e.g. drugs and surgery) attention has focussed on community-based approaches and social marketing campaigns as the most appropriate form of intervention. However there is limited evidence in support of substantial effectiveness of such interventions. To date there is little evidence that community-based interventions and social marketing campaigns specifically targeting obesity provide substantial or lasting benefit. Concerns have been raised about potential negative effects created by a focus of these interventions on body shape and size, and of the associated media targeting of obesity. A more appropriate strategy would be to enact high-level policy and legislative changes to alter the obesogenic environments in which we live by providing incentives for healthy eating and increased levels of physical activity. Research is also needed to improve treatments available for individuals already obese.

To compare the effect of obesity and related risk factors on 10-year mortality in two cohorts of older adults of African descent; one from the United States and one from Nigeria. Study participants were community residents aged 70 or older of African descent living in Indianapolis, Indiana (N = 1,269) or Ibadan, Nigeria (1,197). We compared survival curves between the two cohorts by obesity class and estimated the effect of obesity class on mortality in Cox proportional hazards models controlling for age, gender, alcohol use, and smoking history, and the cardiometabolic biomarkers blood pressure, triglycerides, high-density lipoprotein, low-density lipoprotein, and C-reactive protein. We found that underweight was associated with an increased risk of death in both the Yoruba (hazards ratio = 1.35, 95% confidence interval: 1.12-1.63) and African American samples (hazards ratio = 2.49, 95% confidence interval: 1.40-4.43) compared with those with normal weight. The overweight and obese participants in both cohorts experienced survival similar to the normal weight participants. Controlling for cardiometabolic biomarkers had little effect on the obesity-specific hazard ratios in either cohort. Despite significant differences across these two cohorts in terms of obesity and biomarker levels, overall 10-year survival and obesity class-specific survival were remarkably similar. © The Author 2014.

Seminomas occur infrequently in birds. Two cases of bilateral malignant seminomas in unrelated trumpeter hornbills (Bycanistes buccinator) are described. Case 1 was a 22-year-old trumpeter hornbill submitted for necropsy because of sudden death at a zoo in California. Postmortem examination revealed multiple masses within the body cavity, 2 of which replaced both testes. Case 2 was a 19-year-old trumpeter hornbill at a zoo in North Carolina that underwent exploratory surgery for a suspected gastrointestinal obstruction. Both testes were diffusely enlarged, compressing and replacing the adjacent kidneys. In both birds, the masses were composed of discrete, round to polyhedral cells, typical of seminomas. Examination of the ancestry of the hornbills showed they were unrelated to each other, suggesting a potential predisposition for these birds to develop seminomas.

Obesity in the elderly is associated with exacerbation of functional decline (dependency), that occurs with aging, because of decreased muscle mass and strength, and increased joint dysfunction. Consequently, there is progressive loss of independence, autonomy, chronic pain and impaired quality of life. The weight loss can bring benefits in all these aspects, especially when accompanied by exercises. Elderly patients with morbid obesity may be submitted to surgical treatment, taking into account that the massive weight loss, eventually caused by bariatric surgery, may exacerbate the loss of muscle mass and nutritional complications that may bring harm to the overall health and quality of life of these patients. The functional assessment of elderly patients, candidates for bariatric surgery and the extent to which surgery can bring benefits to the patients, in the field of functionality, has still to be determined. To describe profile functionality in obese elderly referred to a bariatric surgery program. Patients with age ≥ 60 and BMI ≥ 35 underwent comprehensive geriatric assessment that evaluates co morbidities, medication use, ability to perform basic activities of daily living and instrumental activities of daily living, and the "Timedupandgo" test to evaluate mobility, whose cut-off point was ≤ 10 seconds. Statistical analysis was performed in order to see if there is a positive correlation of dependency with BMI and age (over or under 65 years). Results Forty subjects have completed evaluation. The mean age was 64.1 years (60-72) and 75% were women. They had an average weight of 121.1 kg (72.7-204) and a mean BMI of 47.2 kg/m2 (35.8-68.9). 16 patients (40%) have shown dependency for activities of daily living, 19 (47,5%) for instrumental activities of daily living and 20 patients (50%) had a "Timedupandgo" test over 10 seconds. Statistical analysis (t-Student, Mann-Whitney, Binary Logistic Regression) has shown positive correlation of dependency in

Mediation of the bidirectional relations between obesity and depression among women.

Vittengl, Jeffrey R

2018-06-01

Past research established that obesity increases risk for development of depression, and depression increases risk for development of obesity. The current study tested physical impairment (difficulty with instrumental activities of daily living), social dysfunction (low social support and high social strain), and emotional eating (using food to cope with stress) as mediators of the bidirectional, longitudinal relations between depression and obesity. A national sample of mid-life adults in the United States (N = 7108) was assessed at three time points over 18 years. Depression predicted increases in obesity, and obesity predicted increases in depression, for women but not for men. Among women, path analyses revealed that physical impairment, social dysfunction, and emotional eating mediated development of obesity from depression, and that physical impairment and emotional eating mediated development of depression from obesity. These results suggest that prevention or treatment of obesity-linked depression and depression-linked obesity in women may need to address multiple connections between these disorders.

Adolescent obesity is a chronic disease that is impacted from each patient's biopsychosocial milieu. Successfully treating pediatric obesity requires long-term, innovative, systematic involvement to facilitate patient and family engagement and change. Extensive chart review was done for three obese adolescents who underwent comprehensive weight management in an adolescent clinic seen within the past 5 years. The charts were reviewed starting from the time of initial contact through the last visit in the clinic. The patients are no longer receiving care within the clinic. The patients presented with BMI>99th percentile, family history of obesity, severe psychosocial stressors, and multiple obesity-related comorbidities. Their treatment involved comprehensive multidisciplinary intervention in an adolescent weight management clinic within a tertiary care center. In addition to rigorous support through frequent office visits, these patients all eventually required temporary, alternative living arrangements to successfully implement recommendations. One patient resided with another family member; two went to inpatient weight management program care for 2-3 months. All subjects successfully lost weight when away from their primary residence, and they demonstrated improvement or resolution of comorbidities. This case series of three adolescents who underwent comprehensive obesity evaluation and treatment demonstrates multidisciplinary care across interconnected treatment programs and active engagement of family. Those who maintained successful weight loss reduced sedentary time, demonstrated family support (e.g., key members attending follow-up visits), and altered their living environment and were committed to their own health goals.

New PHA products using unrelated carbon sources

2011-01-01

Polyhydroxyalkanoates (PHA) are natural polyesters stored by a wide range of bacteria as carbon source reserve. Due to its chemical characteristics and biodegradability PHA can be used in chemical, medical and pharmaceutical industry for many human purposes. Over the past years, few Burkholderia species have become known for production of PHA. Aside from that, these bacteria seem to be interesting for discovering new PHA compositions which is important to different industrial applications. In this paper, we introduce two new strains which belong either to Burkholderia cepacia complex (Bcc) or genomovar-type, Burkholderia cepacia SA3J and Burkholderia contaminans I29B, both PHA producers from unrelated carbon sources. The classification was based on 16S rDNA and recA partial sequence genes and cell wall fatty acids composition. These two strains were capable to produce different types of PHA monomers or precursors. Unrelated carbon sources were used for growth and PHA accumulation. The amount of carbon source evaluated, or mixtures of them, was increased with every new experiment until it reaches eighteen carbon sources. As first bioprospection experiments staining methods were used with colony fluorescent dye Nile Red and the cell fluorescent dye Nile Blue A. Gas chromatography analysis coupled to mass spectrometry was used to evaluate the PHA composition on each strain cultivated on different carbon sources. The synthesized polymers were composed by short chain length-PHA (scl-PHA), especially polyhydroxybutyrate, and medium chain length-PHA (mcl-PHA) depending on the carbon source used. PMID:24031764

The prevention of obesity in children with DD is a pressing public health issue, with implications for health status, independent living, and quality of life. Substantial evidence suggests that children with developmental disabilities (DD), including those with intellectual disabilities (ID) and autism spectrum disorder (ASD), have a prevalence of obesity at least as high if not higher than their typically developing peers. The paper reviews what is known about the classic and unique risk factors for childhood obesity in these groups of children, including dietary, physical activity, sedentary behavior, and family factors, as well as medication use. We use evidence from the literature to make the case that primary prevention at the individual/family, school and community levels will require tailoring of strategies and adapting existing intervention approaches.

"Living High-Training Low" (LHTL) is effective for the improvement of athletic ability; however, little is known about the effect of LHTL on obese individuals. The present study determined whether LHTL would have favorable influence on body composition, rebalance the appetite hormones, and explore the underlying mechanism. Adolescents with obesity [body mass index (BMI) >30 kg/m] were randomly assigned to "Living Low-Training Low" (LLTL, n = 19) group that slept in a normobaric normoxia condition and the LHTL (n = 16) group slept in a normobaric hypoxia room (14.7% PO2 ∼2700 m). Both groups underwent the same aerobic exercise training program. Morphological, blood lipids, and appetite hormones were measured and assessed. After the intervention, the body composition improved in both groups, whereas reductions in body weight (BW), BMI, and lean body mass increased significantly in the LHTL group (all, P < .05). In the LLTL group, cholecystokinin (CCK) decreased remarkably (P < .05) and CCK changes were positively associated with changes in BW (r = 0.585, P = .011) and BMI (r = 0.587, P = .010). However, in the LHTL group, changes in plasma glucagon-like peptide-1 (GLP-1) and interleukin-6 (IL-6) levels, positively correlated with each other (r = 0.708, P = .015) but negatively with BW changes (r = -0.608, P = .027 and r = -0.518, P = .048, respectively). The results indicated that LHTL could induce more weight loss safely and efficiently as compared to LLTL and increase the plasma GLP-1 levels that may be mediated by IL-6 to rebalance the appetite. Thus, an efficient method to treat obesity and prevent weight regain by appetite rebalance in hypoxia condition was established.

A sample of Malaysians in the Klang Valley indicating their decision on becoming unrelated living kidney donors was surveyed regarding huge amounts of financial incentives to be rewarded to them. From the 1310 respondents, 72.1% said "no" on becoming a living donor. The reason "I don't think humans can live with only one kidney" scored the highest (35.6%), and from the 27.9% of the respondents who are willing to donate their organ with the right financial incentive, most of the respondents picked the reasons "I want to do something noble in life" (50%), and monetary reason scored the lowest (6.2%), indicating that financial incentive is not a major reason guiding individuals' decision on becoming living donors. We suggest that the government should put priority at targeting public education to raise the understanding on the risk, safety and the quality of life of donation and transplantation, and improving the public trust on the donation and the surgical methods to carry out transplantation. © 2014 John Wiley & Sons A/S.

Male obesity and subfertility, is it really about increased adiposity?

PubMed Central

McPherson, Nicole O; Lane, Michelle

2015-01-01

The prevalence of overweight and obesity in reproductive-aged men is increasing worldwide, with >70% of men >18 years classified as overweight or obese in some western nations. Male obesity is associated with male subfertility, impairing sex hormones, reducing sperm counts, increasing oxidative sperm DNA damage and changing the epigenetic status of sperm. These changes to sperm function as a result of obesity, are further associated with impaired embryo development, reduced live birth rates and increased miscarriage rates in humans. Animal models have suggested that these adverse reproductive effects can be transmitted to the offspring; suggesting that men's health at conception may affect the health of their children. In addition to higher adiposity, male obesity is associated with comorbidities, including metabolic syndrome, hypercholesterolemia, hyperleptinemia and a pro-inflammatory state, all which have independently been linked with male subfertility. Taken together, these findings suggest that the effects of male obesity on fertility are likely multifactorial, with associated comorbidities also influencing sperm, pregnancy and subsequent child health.

The cases of gigantism sisters with somatotroph adenomas unrelated to multiple endocrine neoplasia (MEN) Type 1 are reported. The sisters grew rapidly since they were 5 or 6 years old and were diagnosed to have gigantism with pituitary adenoma by computed tomographic scan and magnetic resonance imaging. A serum endocrinological examination showed the elevated growth hormone values. After thyroxine-releasing hormone stimulation, growth hormone values exhibited a paradoxical rise. They were supposed to be unrelated to MEN Type 1, because analysis of the 11th chromosomes and the other endocrine functions were normal. They were operated on by the transphenoidal method. Immunohistochemical staining of both tumor specimens confirmed somatotroph adenomas. Pituitary adenoma associated with MEN Type 1 is a well-recognized entity. However, the sporadic occurrence of pituitary adenoma unrelated to MEN Type 1, especially in siblings, is extremely rare. Fifteen cases of pituitary adenomas in siblings were described in the literature. As for gigantism, only two brothers were reported. Our case of gigantism sisters is the second sporadic case. In our review of the isolated cases of pituitary adenoma in siblings described in the literature, 12 (70%) of 17 cases including ours are acromegaly or gigantism. This incidence is much higher than that of MEN Type 1 patients with pituitary adenomas. The cause of the familial occurrence of pituitary adenomas is still unclear, although autosomal recessive inheritance has been suggested. It has been stated that point mutations in codon 201 or 227 of the Gs alpha gene located in chromosome 20 were found in about 35 to 40% of somatotroph adenomas.(ABSTRACT TRUNCATED AT 250 WORDS)

Our current generation of young people could become the first generation to live shorter lives than their parents. Families need resources in their community to address this issue. Identifying barriers and facilitators of community organizations to offer obesity-related services is a first step in understanding sustainable community programs. The objective of this study is to identify common barriers and facilitators in community organizational programs designed to prevent or reduce pediatric obesity. We conducted an exploratory qualitative research study based on grounded theory. Thirty-six community organizations were identified based on self-descriptions of goals involving pediatric obesity. Semi-structured, systematic, face-to-face interviews among program directors (n = 24) were recorded, transcribed, and coded for recurrent themes. Relevant themes were abstracted from interviews by a standardized iterative process by two independent reviewers between December 2007 and November 2008. Theme discordance was reconciled by a third reviewer. Seventy percent of organizations indicated that obesity prevention/treatment was their explicit goal with remaining groups indicating healthy lifestyles as a more general goal. Facilitators to provision of these programs included: programmatic enhancements such as improved curriculums (73%), community involvement such as volunteers (62.5%), and partnerships with other programs (54.2%). Barriers that threatened sustainability included lack of consistent funding (43.8%), lack of consistent participation from the target population (41.7%) and lack of support staff (20.8%). New approaches in fostering partnerships between organizations need to be developed. Building coalitions and engaging community members in developing community based programs may be a helpful strategy to strengthen community-based programs to address the pediatric obesity epidemic.

Effects of urban sprawl on obesity.

Zhao, Zhenxiang; Kaestner, Robert

2010-12-01

In this paper, we examine the effect of changes in population density-urban sprawl-between 1970 and 2000 on BMI and obesity of residents in metropolitan areas in the U.S. We address the possible endogeneity of population density by using a two-step instrumental variables approach. We exploit the plausibly exogenous variation in population density caused by the expansion of the U.S. Interstate Highway System, which largely followed the original 1947 plan for the Interstate Highway System. We find a negative association between population density and obesity, and estimates are robust across a wide range of specifications. Estimates indicate that if the average metropolitan area had not experienced the decline in the proportion of population living in dense areas over the last 30 years, the rate of obesity would have been reduced by approximately 13%.

Obesity and the built environment at different urban scales: examining the literature.

PubMed

Garfinkel-Castro, Andrea; Kim, Keuntae; Hamidi, Shima; Ewing, Reid

2017-01-01

The majority of people now live in an urban (or suburban) environment. The built (material) environment, its vehicular and pedestrian infrastructure, buildings, and public realm places, are the places used for working, living, and recreating. The environment currently favors and facilitates motorized vehicles generally, and private automobiles especially. The prioritization given to vehicles reduces opportunities for other, more active modes of travel such as walking and bicycling. Though the built environment cannot be said to directly affect human obesity, the built environment clearly has a relationship to obesity as a consequence of physical activity. Most concerning is that rates of obesity have risen as cars have become increasingly privileged, leading to places that favor driving over walking or bicycling. This review examines current empirical literature on the environment and obesity at 3 key urban scales: macro, meso, and micro. Other key issues examined include longitudinal studies and self-selection bias. Evidence for a relationship between urban and suburban environments and obesity is found in the literature, but the lack of longitudinal research and research controlling for self-selection bias remains underrepresented. © The Author(s) 2016.

Commercial living non-related organ transplantation: a viewpoint from a developed country.

PubMed

Hoyer, Peter F

2006-10-01

In developed countries, the use of living unrelated donors is restricted to purely altruistic donors who have a close and emotional relationship with the recipients. By law, commercial transplantation is illegal. Increasing shortness of donors, the excellent results of kidney transplants from spousal and living unrelated donors as well as the very low risk for the donor has been used as an argument for paid organ donation. Arguments in favour are the relief of donor-organ shortage, short waiting times for renal transplantation, economic benefits for the donor as well as the economic benefits for society by reducing the costs of dialysis by more transplants. Major arguments against are exploitation of the donor, coercion, and a growing black market. Despite the fact that different societies have different norms or reproaches that we are failing our patients and accept the death of thousands, kidney trade has created an environment of corruption and commercialisation, which brings even the cadaver transplant program into disrepute. However, denying the existence of paid organ donation does not contribute to solve the problem. A public discussion about consequences of changing ethics and human rights, rather than pragmatic solutions, is needed.

Incident HNSCCs at HPV-related and HPV-unrelated anatomic sites were detected in HIV-infected participants from pooled data from 17 prospective studies in the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) between 1996 and 2009. HNSCC cases were validated using chart review or cancer registry matching. Risk factors for incident HPV-related and HPV-unrelated HNSCC were explored using mixed effects Poisson regression in a full prospective analysis, and the effect of CD4 prior to cancer diagnosis was examined in a nested case control analysis. 66 HPV-related and 182 HPV-unrelated incident HNSCCs were detected among 82,375 HIV-infected participants. Standardized incidence ratios (SIRs) for both HPV-related (SIR=3.2, 95%CI=2.5-3.4) and HPV-unrelated (SIR=3.0, 95%CI=2.5-4.1) HNSCC were significantly elevated in HIV-infected individuals compared with the US general population. Between 1996 and 2009, the age-standardized HPV-related HNSCC incidence increased non-significantly from 6.8 to 11.4per 100,000 person-years (p-trend=0.31) while the age-standardized incidence of HPV-unrelated HNSCC decreased non-significantly from 41.9 to 29.3 per 100,000 person-years (p-trend=0.16). Lower CD4 cell count prior to cancer diagnosis was significantly associated with increased HPV-related and HPV-unrelated HNSCC risk. The standardized incidence of HPV-related and HPV-unrelated HNSCC are both elevated in HIV-infected individuals. Immunosuppression may have a role in the development of both HPV-related and HPV-unrelated HNSCC. Copyright © 2014 Elsevier Ltd. All rights reserved.

Obesity in children and youth is a major public health concern known to have a significant impact on physical and mental health. Although traditional approaches to obesity have emphasized diet and exercise at the individual level, broader attention to the mental health consequences of obesity is crucial. Individuals who are obese live in a world where they are often less accepted resulting in social exclusion and discrimination. A public health multi-tiered approach to obesity focusing on mental health promotion, prevention, and individualized intervention is presented.

Obesity: a disease or a biological adaptation? An update.

Chaput, J-P; Doucet, E; Tremblay, A

Obesity is characterized by the accumulation of excess body fat and can be conceptualized as the physical manifestation of chronic energy excess. An important challenge of today's world is that our so-called obesogenic environment is conducive to the consumption of energy and unfavourable to the expenditure of energy. The modern, computer-dependent, sleep-deprived, physically inactive humans live chronically stressed in a society of food abundance. From a physiological standpoint, the excess weight gain observed in prone individuals is perceived as a normal consequence to a changed environment rather than a pathological process. In other words, weight gain is a sign of our contemporary way of living or a 'collateral damage' in the physiological struggle against modernity. Additionally, substantial body fat loss can complicate appetite control, decrease energy expenditure to a greater extent than predicted, increase the proneness to hypoglycaemia and its related risk towards depressive symptoms, increase the plasma and tissue levels of persistent organic pollutants that promote hormone disruption and metabolic complications, all of which are adaptations that can increase the risk of weight regain. In contrast, body fat gain generally provides the opposite adaptations, emphasizing that obesity may realistically be perceived as an a priori biological adaptation for most individuals. Accordingly, prevention and treatment strategies for obesity should ideally target the main drivers or root causes of body fat gain in order to be able to improve the health of the population. © 2012 The Authors. obesity reviews © 2012 International Association for the Study of Obesity.

Although peripheral blood stem cells (PBSCs) have replaced bone marrow (BM) as the most common unrelated donor progenitor cell product collected, a direct comparison of concurrent PBSC versus BM donation experiences has not been performed. We report a prospective study of 2726 BM and 6768 PBSC donors who underwent collection from 2004 to 2009. Pain and toxicities were assessed at baseline, during G-CSF administration, on the day of collection, within 48 hours of donation, and weekly until full recovery. Peak levels of pain and toxicities did not differ between the 2 donation processes for most donors. Among obese donors, PBSC donors were at increased risk of grade 2 to 4 pain as well as grade 2 to 4 toxicities during the pericollection period. In contrast, BM donors were more likely to experience grade 2 to 4 toxicities at 1 week and pain at 1 week and 1 month after the procedure. BM donors experienced slower recovery, with 3% still not fully recovered at 24 weeks, whereas 100% of PBSC donors had recovered. Other factors associated with toxicity included obesity, increasing age, and female sex. In summary, this study provides extensive detail regarding individualized risk patterns of PBSC versus BM donation toxicity, suggesting donor profiles that can be targeted with interventions to minimize toxicity.

All age, sex, and racial groups are affected by the obesity epidemic in the United States, although disparities exist among these groups. The Seventh-day Adventists are a religious group of people who are believed to live longer and healthier lives than do their non-Adventist counterparts because they do not smoke or drink alcohol and they eat a healthier diet. This study assessed the prevalence of overweight and obesity among Seventh-day Adventist college students attending 2 private universities in the southern United States. Most students' body mass index (65.8%) was within the normal weight category, 3.7% were underweight, 20.6% were overweight, and 9.9% were obese. Body mass index > or = 25 kg/m2 was more prevalent among men and African Americans. In all ethnic subgroups, the prevalence of overweight and obesity was lower than that among non-Adventist students reported in other studies.

We estimated overweight and obesity (OWOB) prevalence of children in US-Affiliated Pacific jurisdictions (USAP) of the Children's Healthy Living Program compared with the contiguous United States. We searched peer-reviewed literature and government reports (January 2001-April 2014) for OWOB prevalence of children aged 2 to 8 years in the USAP and found 24 sources. We used 3 articles from National Health and Nutrition Examination Surveys for comparison. Mixed models regressed OWOB prevalence on an age polynomial to compare trends (n = 246 data points). In the USAP, OWOB prevalence estimates increased with age, from 21% at age 2 years to 39% at age 8 years, increasing markedly at age 5 years; the proportion obese increased from 10% at age 2 years to 23% at age 8 years. The highest prevalence was in American Samoa and Guam.

Objectives: To determine the prevalence of hypertension, obesity, hematuria, and proteinuria among healthy adolescents and to determine the associated risk factors. Methods: This is a cross-sectional study of 8 intermediate schools in Jeddah, Saudi Arabia between March 2015 and June 2015. Samples were selected randomly and equal proportions from each school for both genders were ensured. Both blood pressure and body mass index were measured and a brief questionnaire was filled out for the specified studied group. Urine dipstick analysis was carried out for 294 children. A second questionnaire was completed for hypertensive and obese subjects in addition to those with hematuria and proteinuria. Results: A total of 401 children (200 males) with a mean (SD) age of 13.87 (1.27) were included. Hypertension was found in 17.2% with a male to female ratio of 1.4:1. Pre-hypertension was found in 4.2% of our sample with a male to female ratio of 2.1:1. Obesity was found in 19.2% with a male to female ratio of 1.5:1. Obesity was found to be the most significant risk factor for hypertension with a related risk: 2.87, 95% and confidence interval: 1.9-4.3. For urine abnormalities, 10.2% of samples were positive for proteinuria, 17% for hematuria, and 3.1% for both. Conclusion: It was found that there is a positive correlation between the incidence of obesity and hypertension in adolescents. Hematuria and proteinuria were also found to be high. Screening and prevention programs are therefore recommended. PMID:27652364

Thoughts in flight: automation use and pilots' task-related and task-unrelated thought.

The objective was to examine the relationship between cockpit automation use and task-related and task-unrelated thought among airline pilots. Studies find that cockpit automation can sometimes relieve pilots of tedious control tasks and afford them more time to think ahead. Paradoxically, automation has also been shown to lead to lesser awareness. These results prompt the question of what pilots think about while using automation. A total of 18 airline pilots flew a Boeing 747-400 simulator while we recorded which of two levels of automation they used. As they worked, pilots were verbally probed about what they were thinking. Pilots were asked to categorize their thoughts as pertaining to (a) a specific task at hand, (b) higher-level flight-related thoughts (e.g.,planning ahead), or (c) thoughts unrelated to the flight. Pilots' performance was also measured. Pilots reported a smaller percentage of task-at-hand thoughts (27% vs. 50%) and a greater percentage of higher-level flight-related thoughts (56% vs. 29%) when using the higher level of automation. However, when all was going according to plan, using either level of automation, pilots also reported a higher percentage of task-unrelated thoughts (21%) than they did when in the midst of an unsuccessful performance (7%). Task-unrelated thoughts peaked at 25% when pilots were not interacting with the automation. Although cockpit automation may provide pilots with more time to think, it may encourage pilots to reinvest only some of this mental free time in thinking flight-related thoughts. This research informs the design of human-automation systems that more meaningfully engage the human operator.

Saldívar-Cerón, Héctor Iván; Garmendia Ramírez, Alberto; Rocha Acevedo, Marco Antonio; Pérez-Rodríguez, Pedro

In Mexico, the prevalence of overweight and obesity is 34.4% in school-age children (ENSANUT 2012), which may induce a vicious cycle of flatfoot-plantalgia-sedentarism-obesity, although the presence and degree of flatfoot in school-age children with obesity has not yet been described in a Mexican population. The objective of the study was to determine the prevalence of flatfoot and its association with obesity in school-age children living in Tampico. An analytical and cross-sectional study with 1128 students, 48.8% male and 51.2% female, 9- to 11-years of age. Anthropometric measurements (weight and height) were performed. Body mass index (BMI) was calculated and obesity was considered a BMI percentile >95. Plantar footprint was photographed via a podoscope using Denis classification to diagnose flatfoot grades. The prevalence of overweight/obesity was 49.1% and of flatfoot was 12.1% (male: 8.1%, female: 4%, p = 0.28). The association between obesity and flatfoot was significant (p <0.001) and there was a 2.5 times higher risk of overweight-obese children compared to those of normal weight. There is an association between obesity and flatfoot. We suggest implementing secondary prevention measures in this population. Copyright © 2014 Hospital Infantil de México Federico Gómez.

DIDS is a unique form of combined immune deficiency characterized by an unusual susceptibility to cutaneous viral infections, severe allergies with eosinophilia and elevated immunoglobulin E titers, autoimmunity, and cancer. HSCT is considered the standard of care for this deadly disease. We have retrospectively analyzed the outcome of allogeneic HSCT from unrelated donors in patients with DIDS. Data from four patients, with five transplants, are presented. All patients received transplants from unrelated donors' BM, except for one patient who received a cord blood transplant. The conditioning regimens were based on myeloablative protocols for BM derived transplants; a NM regimen was pursued for the patient who received a cord blood transplant, which resulted in graft rejection. Although recurrent pneumonia and skin infections resolved immediately after transplantation, all patients subsequently developed human herpesvirus infection, including cutaneous herpetic lesions, cytomegalovirus reactivation, and zona zoster, which could be attributed to the use of ATG. Despite the presence of serious morbidities prior to transplantation, all patients recovered successfully. DIDS can be successfully treated with allogeneic HSCT from unrelated donors following a myeloablative conditioning regimen, with a reasonable safety profile. © 2017 John Wiley & Sons A/S.

Background Obesity is a major risk factor for emerging non-communicable diseases (NCDS) in middle income countries including South Africa (SA). Understanding the multiple and complex determinants of obesity and their true population attributable impact is critical for informing and developing effective prevention efforts using scientific based evidence. This study identified contextualised high impact factors associated with obesity in South Africa. Methods Analysis of three national cross sectional (repeated panel) surveys, using a multilevel logistic regression and population attributable fraction estimation allowed for identification of contextualised high impact factors associated with obesity (BMI>30 kg/m2) among adults (15years+). Results Obesity prevalence increased significantly from 23.5% in 2008 to 27.2% in 2012, with a significantly (p-value<0.001) higher prevalence among females (37.9% in 2012) compared to males (13.3% in 2012). Living in formal urban areas, white ethnicity, being married, not exercising and/or in higher socio-economic category were significantly associated with male obesity. Females living in formal or informal urban areas, higher crime areas, African/White ethnicity, married, not exercising, in a higher socio-economic category and/or living in households with proportionate higher spending on food (and unhealthy food options) were significantly more likely to be obese. The identified determinants appeared to account for 75% and 43% of male and female obesity respectively. White males had the highest relative gain in obesity from 2008 to 2012. Conclusions The rising prevalence of obesity in South Africa is significant and over the past 5 years the rising prevalence of Type-2 diabetes has mirrored this pattern, especially among females. Targeting young adolescent girls should be a priority. Addressing determinants of obesity will involve a multifaceted strategy and requires at individual and population levels.

The authors compare the prevalence of obesity for National Core Indicators (NCI) survey participants with intellectual disability and the general U.S. adult population. In general, adults with intellectual disability did not differ from the general population in prevalence of obesity. For obesity and overweight combined, prevalence was lower for males with intellectual disability than for the general population but similar for women. There was higher prevalence of obesity among women with intellectual disability, individuals with Down syndrome, and people with milder intellectual disability. Obesity prevalence differed by living arrangement, with institutional residents having the lowest prevalence and people living in their own home the highest. When level of intellectual disability was taken into account, these differences were reduced, but some remained significant, especially for individuals with milder disability.

Knowledge of haplotype phase is valuable for many analysis methods in the study of disease, population, and evolutionary genetics. Considerable research effort has been devoted to the development of statistical and computational methods that infer haplotype phase from genotype data. Although a substantial number of such methods have been developed, they have focused principally on inference from unrelated individuals, and comparisons between methods have been rather limited. Here, we describe the extension of five leading algorithms for phase inference for handling father-mother-child trios. We performed a comprehensive assessment of the methods applied to both trios and to unrelated individuals, with a focus on genomic-scale problems, using both simulated data and data from the HapMap project. The most accurate algorithm was PHASE (v2.1). For this method, the percentages of genotypes whose phase was incorrectly inferred were 0.12%, 0.05%, and 0.16% for trios from simulated data, HapMap Centre d'Etude du Polymorphisme Humain (CEPH) trios, and HapMap Yoruban trios, respectively, and 5.2% and 5.9% for unrelated individuals in simulated data and the HapMap CEPH data, respectively. The other methods considered in this work had comparable but slightly worse error rates. The error rates for trios are similar to the levels of genotyping error and missing data expected. We thus conclude that all the methods considered will provide highly accurate estimates of haplotypes when applied to trio data sets. Running times differ substantially between methods. Although it is one of the slowest methods, PHASE (v2.1) was used to infer haplotypes for the 1 million–SNP HapMap data set. Finally, we evaluated methods of estimating the value of r2 between a pair of SNPs and concluded that all methods estimated r2 well when the estimated value was ⩾0.8. PMID:16465620

Overweight or obesity may cause many chronic illnesses. Furthermore, several studies have shown that high body mass index is associated with mortality and morbidity among the elderly. Therefore, obesity or being overweight could adversely affect the performance of activities of daily living. In this study our aim was to investigate the association between Body Mass Index and Activity of Daily Living in Homecare Patients. The records of 2016 from the homecare unit of Sisli Hamidiye Etfal Training and Research Hospital were retrospectively reviewed. During this period, 1105 patients visited this facility. Unconscious or bedridden patients (hemiplegia, hemiparesia, and tetraparesis) and patients with incomplete data were excluded from the study. Therefore, the survey was completed with 250 files, which included all the data needed for our research. Age, gender, Body Mass Index and Barthel Index scores were recorded to the statistical program; p≤0.05 was considered as statistically significant. One hundred fifty one (60.4%) were women, and 99 (39.6%) were men. The relations between gender and age, weight, and Barthel index scores were not statistically significant. There was a significant positive correlation between weight and Barthel index scores as well as between Body Mass Index and Barthel index scores (r = 0.190; p = 0.003). The patients were divided into two groups: Group-I (underweight and normal weight) and Group-II (overweight and obese). Group-II exhibited a much higher ability to perform Activity of Daily Living than Group-I (p = 0.002). Some studies report that obesity is protective against Activity of Daily Living, but the opposite is reported in some others. Our study showed increased values of Body Mass Index and Activity of Daily Living ability, which are indicative of protective effects. The relationship between Body Mass Index and physical disability is not yet proven to be linear.

Eating in the absence of hunger: a genetic marker for childhood obesity in prepubertal boys?

Eating in the absence of hunger (EAH) may be a behavioral trait through which obesity-promoting genes promote positive energy balance. The primary aim of this study was to compare children born at high vs. low risk for obesity with respect to EAH at 5 years of age. This was an observational investigation of families enrolled in the University of Pennsylvania and The Children's Hospital of Philadelphia's Infant Growth Study. Five-year-old children born at high (N = 28) or low (N = 25) risk for obesity on the basis of maternal prepregnancy body weight were evaluated at a hospital-based laboratory. Children consumed 11 snack foods ad libitum after consuming an ad libitum dinner and reporting fullness. Parents reported on snack foods at home and their own eating styles. Nutritive sucking at 3 months of age was evaluated by computerized apparatus. EAH in high-risk boys (mean +/- standard error = 326 +/- 66 kJ] was more than twice that of low-risk boys (mean +/- standard error = 151 +/- 39 kJ), p = 0.03. Among girls, there was a trend for EAH to be associated with increased parental limitations on daughter snack food consumption at home (p = 0.06). EAH was unrelated to 3-month sucking behavior. Genes that promote childhood obesity may partially exert their influence through EAH, an effect that was limited to boys born at risk for obesity. The unique influences of genes and home environment on this trait should be disaggregated in subsequent studies.

Using whole-exome sequencing, we have identified novel de novo heterozygous pleckstrin homology domain-interacting protein ( PHIP ) variants that are predicted to be deleterious, including a frameshift deletion, in two unrelated patients with common clinical features of developmental delay, intellectual disability, anxiety, hypotonia, poor balance, obesity, and dysmorphic features. A nonsense mutation in PHIP has previously been associated with similar clinical features. Patients with microdeletions of 6q14.1, including PHIP , have a similar phenotype of developmental delay, intellectual disability, hypotonia, and obesity, suggesting that the phenotype of our patients is a result of loss-of-function mutations. PHIP produces multiple protein products, such as PHIP1 (also known as DCAF14), PHIP, and NDRP. PHIP1 is one of the multiple substrate receptors of the proteolytic CUL4-DDB1 ubiquitin ligase complex. CUL4B deficiency has been associated with intellectual disability, central obesity, muscle wasting, and dysmorphic features. The overlapping phenotype associated with CUL4B deficiency suggests that PHIP mutations cause disease through disruption of the ubiquitin ligase pathway.

U.S. policy initiatives have sought to improve health through attracting neighborhood supermarket investment. Little evidence exists to suggest that these policies will be effective, in particular where there are socioeconomic barriers to healthy eating. We measured the independent associations and combined interplay of supermarket access and socioeconomic status with obesity. Using data on 9702 UK adults, we employed adjusted regression analyses to estimate measured BMI (kg/m2), overweight (25 ≥ BMI < 30) and obesity (≥30), across participants’ highest educational attainment (three groups) and tertiles of street network distance (km) from home location to nearest supermarket. Jointly-classified models estimated combined associations of education and supermarket distance, and relative excess risk due to interaction (RERI). Participants farthest away from their nearest supermarket had higher odds of obesity (OR 1.33, 95% CI: 1.11, 1.58), relative to those living closest. Lower education was also associated with higher odds of obesity. Those least-educated and living farthest away had 3.39 (2.46–4.65) times the odds of being obese, compared to those highest-educated and living closest, with an excess obesity risk (RERI = 0.09); results were similar for overweight. Our results suggest that public health can be improved through planning better access to supermarkets, in combination with interventions to address socioeconomic barriers. PMID:29068365

During the past decade, the use of umbilical cord blood (CB) as a source of transplantable hematopoietic stem cells has been increasing. Little is known about the psychosocial consequences that later affect parents after unrelated CB donation. The objective of this study was to evaluate the attitudes of mothers toward unrelated donation of umbilical CB for transplantation 6 months after giving birth. A prospective study was performed with a standardized, anonymous questionnaire distributed to 131 women 6 months after CB donation. The questionnaire included topics concerning views about the ethical accuracy of having donated CB, emotional responses after donation, concerns about genetic testing and research with CB samples, attitude toward anonymity between her child and possible unrelated CB recipient, and willingness to repeatedly donate umbilical CB in a next pregnancy. The vast majority (96.1%) stated that they would donate umbilical CB again, and all respondents were certain that their decision to have donated umbilical CB was ethical. With regard to the potential risks of genetic testing and "experimentation" of umbilical CB, a significant correlation (p = 0.01) was found between negative attitudes and the decision not to donate umbilical CB again. Additionally, it was observed that women who had a negative experience concerning the donation of CB would not donate again (p = 0.004). This study shows a high degree of satisfaction of unrelated umbilical CB donation for banking in women 6 months after delivery. Despite a well-performed and detailed informed consent procedure, one of the ongoing issues for the donators in CB banking involves the concern regarding of improper use of the cells, such as genetic testing or experimentation. Accurate and detailed counseling of pregnant women and their partners therefore maximizes the likelihood that they will donate CB for unrelated banking. These data provide a basis for the improvement of donor selection procedures

To examine whether there is an association between neighbourhood deprivation and diagnosed childhood obesity, after accounting for family- and individual-level socio-demographic characteristics. An open cohort of all children aged 0-14 years was followed between January 1, 2000 and December 31, 2010. Childhood residential locations were geocoded and classified according to neighbourhood deprivation. Data were analysed by multilevel logistic regression, with family- and individual-level characteristics at the first level and level of neighbourhood deprivation at the second level. During the study period, among a total of 948,062 children, 10,799 were diagnosed with childhood obesity. Age-adjusted cumulative incidence for diagnosed childhood obesity increased with increasing level of neighbourhood deprivation. Incidence of diagnosed childhood obesity increased with increasing neighbourhood-level deprivation across all family and individual-level socio-demographic categories. The odds ratio (OR) for diagnosed childhood obesity for those living in high-deprivation neighbourhoods versus those living in low-deprivation neighbourhoods was 2.44 (95% confidence interval (CI) = 2.22-2.68). High neighbourhood deprivation remained significantly associated with higher odds of diagnosed childhood obesity after adjustment for family- and individual-level socio-demographic characteristics (OR = 1.70, 95% CI = 1.55-1.89). Age, middle level family income, maternal marital status, low level education, living in large cities, advanced paternal and maternal age, family history of obesity, parental history of diabetes, chronic obstructive pulmonary disease, alcoholism and personal history of diabetes were all associated with higher odds of diagnosed childhood obesity. Our results suggest that neighbourhood characteristics affect the odds of diagnosed childhood obesity independently of family- and individual-level socio-demographic characteristics. © 2014 S.

Infants born at less than  34 weeks' gestational age are at higher risk for morbidity and mortality. Data are limited on the impact of maternal obesity on the very preterm infant. This study reviewed whether maternal obesity further increases the intensive care needs of very preterm infants of less than 34 weeks' gestation. Maternal and neonatal data for live-born singleton births of 23 0/7 to 33 6/7 weeks' gestation delivering in upstate New York were reviewed. BMI categorization followed the National Institutes of Health BMI classification that subdivides obesity into three ascending BMI groups. Records were obtained on 1,224 women, of whom 31.6% were classified with obesity. Despite similar mean gestational age (31 to 31.6 weeks, P = 0.57) and birth weight (1,488 to 1,569 g, P = 0.51) of the infants in the BMI categories, delivery room (DR) resuscitation was more common for infants of women with level III obesity (63.2%, P = 0.04) with a trend toward the continued need for assisted ventilation (54.7%, P = 0.06). Preterm infants of women with level III obesity were more likely to require DR resuscitation with a trend to continued need for ventilatory support beyond 6 hours of age. This could impact utilization of DR resources at delivering hospitals. © 2017 The Obesity Society.

Oportunidades to reduce overweight and obesity in Mexico?

PubMed

Andalón, Mabel

2011-09-01

This paper investigates the causal effect of Oportunidades, a conditional cash-transfer program in Mexico, on overweight and obesity of adolescents living in poor rural areas. Affecting youth weight was not a goal of this program. However, health economics research suggests that the provision of schooling, health information sessions and sizable cash transfers to Oportunidades participants could have substantially changed their overweight and obesity rates. Exploiting an exogenous jump in program participation by means of a fuzzy Regression Discontinuity (RD) design, the evidence of this paper suggests that Oportunidades decreased obesity among participant women. The identified local average treatment effect (LATE) at the threshold for program eligibility suggests that female obesity would decrease if the program was expanded to cover slightly better-off households. The design of the program does not allow disentangling the causal pathways that contributed to the lower prevalence of obesity among women, but the effect likely resulted from increased access to information and schooling, improved dietary quality, increased monitoring of health outcomes and (possibly) increased physical activity. Suggestive evidence shows that teen pregnancy rates were higher among non-participants. Therefore, weight gain after childbirth might also explain higher obesity rates among non-participant females.

A Review of Adult Obesity Research in Malaysia.

PubMed

Lim, K G

2016-06-01

A literature search of articles as detailed in the paper Bibliography of clinical research in Malaysia: methods and brief results, using the MESH terms Obesity; Obesity, Abdominal; and Overweight; covering the years 2000 till 2015 was undertaken and 265 articles were identified. Serial population studies showed that the prevalence of obesity increased rapidly in Malaysia in the last decade of the twentieth century. This follows the rising availability of food per capita which had been begun two to three decades previously. Almost every birth cohort, even up to those in their seventh decade increased in prevalence of overweight and obesity between 1996 and 2006. However, the rise in prevalence in obesity appears to have plateaued after the first decade of the twentieth century. Women are more obese than men and Malays and Indians are more obese than Chinese. The Orang Asli (Aborigines) are the least obese ethnic group in Malaysia but that may change with socioeconomic development. Neither living in rural areas nor having low income protects against obesity. On the contrary, a tertiary education and an income over RM4,000/month is associated with less obesity. Malaysians are generally not physically active enough, in the modes of transportation they use and how they use their leisure time. Other criteria and measures of obesity have been investigated, such as the relevance of abdominal obesity, and the Asian criteria or Body Mass Index (BMI) cut-offs value of 23.0 kg/m 2 for overweight and 27.0 kg/m 2 for obesity, with the view that the risk of diabetes and other chronic diseases start to increase at lower values in Asians compared to Europeans. Nevertheless the standard World Health Organization (WHO) guidelines for obesity are still most widely used and hence is the best common reference. Guidelines for the management of obesity have been published and projects to combat obesity are being run. However, more effort needs to be invested. Studies on intervention

We estimated overweight and obesity (OWOB) prevalence of children in US-Affiliated Pacific jurisdictions (USAP) of the Children’s Healthy Living Program compared with the contiguous United States. We searched peer-reviewed literature and government reports (January 2001–April 2014) for OWOB prevalence of children aged 2 to 8 years in the USAP and found 24 sources. We used 3 articles from National Health and Nutrition Examination Surveys for comparison. Mixed models regressed OWOB prevalence on an age polynomial to compare trends (n = 246 data points). In the USAP, OWOB prevalence estimates increased with age, from 21% at age 2 years to 39% at age 8 years, increasing markedly at age 5 years; the proportion obese increased from 10% at age 2 years to 23% at age 8 years. The highest prevalence was in American Samoa and Guam. PMID:25393168

Migrant Networks and Pathways to Child Obesity in Mexico

2011-01-01

The purpose of this paper is twofold: 1) to assess the link between migrant networks and becoming overweight or obese and 2) to explore the pathways by which migrant networks may contribute to the increasing overweight and obese population of children in Mexico. Using two waves of the Mexican Family Life Survey (MxFLS), we find that children and adolescents (ages 3 to 15) living in households with migrant networks are at an increased risk of becoming overweight or obese over the period of observation, relative to their peers with no migrant networks. Sedentary behavior and household-level measures of economic wellbeing explain some of the association between networks and changes in weight status, but the role of extended networks remains significant. Community-level characteristics related to migration do not account for any of the observed relationship between household-level networks and becoming overweight or obese. PMID:21277058

The human distal gut harbours a vast ensemble of microbes (the microbiota) that provide important metabolic capabilities, including the ability to extract energy from otherwise indigestible dietary polysaccharides. Studies of a few unrelated, healthy adults have revealed substantial diversity in their gut communities, as measured by sequencing 16S rRNA genes, yet how this diversity relates to function and to the rest of the genes in the collective genomes of the microbiota (the gut microbiome) remains obscure. Studies of lean and obese mice suggest that the gut microbiota affects energy balance by influencing the efficiency of calorie harvest from the diet, and how this harvested energy is used and stored. Here we characterize the faecal microbial communities of adult female monozygotic and dizygotic twin pairs concordant for leanness or obesity, and their mothers, to address how host genotype, environmental exposure and host adiposity influence the gut microbiome. Analysis of 154 individuals yielded 9,920 near full-length and 1,937,461 partial bacterial 16S rRNA sequences, plus 2.14 gigabases from their microbiomes. The results reveal that the human gut microbiome is shared among family members, but that each person's gut microbial community varies in the specific bacterial lineages present, with a comparable degree of co-variation between adult monozygotic and dizygotic twin pairs. However, there was a wide array of shared microbial genes among sampled individuals, comprising an extensive, identifiable 'core microbiome' at the gene, rather than at the organismal lineage, level. Obesity is associated with phylum-level changes in the microbiota, reduced bacterial diversity and altered representation of bacterial genes and metabolic pathways. These results demonstrate that a diversity of organismal assemblages can nonetheless yield a core microbiome at a functional level, and that deviations from this core are associated with different physiological states (obese

Obesity is a serious health problem with strong genetic determination. Copy number variation (CNV) is a common type of genomic variant associated with some complex human diseases. However, it is not clear how CNVs contribute to the etiology of obesity. In this study, we examined 1,000 unrelated US whites to search for CNVs that may predispose to obesity. We focused our analyses on the Prader-Willi syndrome (PWS) critical region (chromosome 15q11-q13), because the PWS region is a hotspot for CNV generation and obesity is one of the major clinical manifestations for chromosome abnormalities at this region. We constructed a map containing 39 CNVs at the PWS critical region with CNV occurrence rates higher than 1%. Among them, three CNVs were significantly associated with body fat mass (P < 0.05), with a higher copy number (CN) associated with an increase of 5.08-9.77 kg in body fat mass. These three CNVs are close to two known PWS genes, NDN (necdin homolog) and C15orf2 (chromosome 15 open reading frame 2), and partially overlap with another obesity gene PWRN1 (Prader-Willi region nonprotein-coding RNA 1). Interestingly, our recently published whole genome association scan study using the same sample by examining single-nucleotide polymorphisms (SNPs) did not find any significant associations at these CNV regions, suggesting the importance of examining both CNVs and SNPs for better understanding of genetic basis of obesity. Further studies are warranted to validate these CNVs and their importance to obesity.

Neighborhoods (and people) are not static, and are instead shaped by dynamic long-term processes of change (and mobility). Using the Geographic Research on Wellbeing survey, a population-based sample of 2339 Californian mothers, we characterize then investigate how long-term latent neighborhood poverty trajectories predict the likelihood of obesity, taking into account short-term individual residential mobility. We find that, net of individual and neighborhood-level controls, living in or moving to tracts that experienced long-term low poverty was associated with lower odds of being obese relative to living in tracts characterized by long-term high poverty.

The goal of this study was to investigate depression and anxiety levels of mothers whose child (7-11 years) and adolescent (12-18 years) offspring had obesity, as well as those mothers' attitudes toward their children and their family relationships. This is a cross-sectional, case-control study of 100 dyads. All mothers completed the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Parental Attitude Research Instrument, and the Family Assessment Device. Maternal state anxiety in the group with obesity was significantly higher than controls (p = 0.03). As measured by Family Assessment Device, affective involvement (p = 0.05) and behavior control (p = 0.00) scores were significantly higher for those with obesity. Obesity and adolescence have independent effects on maternal state anxiety; affective involvement domain of family function is affected by both obesity and its interaction with adolescence, while behavior control domain is singularly affected by obesity. Our results may demonstrate that, for the mothers of children who have obesity, this condition may have an adverse effect on their lives and their family relationships. Pediatric obesity and developmental stage of offspring may have different effects on maternally reported psychometric variables. Cross-sectional design may hinder causal explanations. Further studies with longitudinal designs are needed. © The Author(s) 2015.

Maternal pre-pregnancy obesity and risk for inattention and negative emotionality in children.

PubMed

Rodriguez, Alina

2010-02-01

This study aimed to replicate and extend previous work showing an association between maternal pre-pregnancy adiposity and risk for attention deficit hyperactivity disorder (ADHD) symptoms in children. A Swedish population-based prospective pregnancy-offspring cohort was followed up when children were 5 years old (N = 1,714). Mothers and kindergarten teachers rated children's ADHD symptoms, presence and duration of problems, and emotionality. Dichotomized outcomes examined difficulties of clinical relevance (top 15% of the distribution). Analyses adjusted for pregnancy (maternal smoking, depressive symptoms, life events, education, age, family structure), birth outcomes (birth weight, gestational age, infant sex) and concurrent variables (family structure, maternal depressive symptoms, parental ADHD symptoms, and child overweight) in an attempt to rule out confounding. Maternal pre-pregnancy overweight and obesity predicted high inattention symptom scores and obesity was associated with a two-fold increase in risk of difficulties with emotion intensity and emotion regulation according to teacher reports. Means of maternal ratings were unrelated to pre-pregnancy body mass index (BMI). Presence and duration of problems were associated with both maternal over and underweight according to teachers. Despite discrepancies between maternal and teacher reports, these results provide further evidence that maternal pre-pregnancy overweight and obesity are associated with child inattention symptoms and extend previous work by establishing a link between obesity and emotional difficulties. Maternal adiposity at the time of conception may be instrumental in programming child mental health, as prenatal brain development depends on maternal energy supply. Possible mechanisms include disturbed maternal metabolic function. If maternal pre-pregnancy obesity is a causal risk factor, the potential for prevention is great.

Computation of ancestry scores with mixed families and unrelated individuals.

The issue of robustness to family relationships in computing genotype ancestry scores such as eigenvector projections has received increased attention in genetic association, and is particularly challenging when sets of both unrelated individuals and closely related family members are included. The current standard is to compute loadings (left singular vectors) using unrelated individuals and to compute projected scores for remaining family members. However, projected ancestry scores from this approach suffer from shrinkage toward zero. We consider two main novel strategies: (i) matrix substitution based on decomposition of a target family-orthogonalized covariance matrix, and (ii) using family-averaged data to obtain loadings. We illustrate the performance via simulations, including resampling from 1000 Genomes Project data, and analysis of a cystic fibrosis dataset. The matrix substitution approach has similar performance to the current standard, but is simple and uses only a genotype covariance matrix, while the family-average method shows superior performance. Our approaches are accompanied by novel ancillary approaches that provide considerable insight, including individual-specific eigenvalue scree plots. © 2017 The Authors.

Obesity is a major threat to public health worldwide, and there is now mounting evidence favoring a role for the central nervous system (CNS) in weight control. A causal relationship has been recognized in both monogenic (e.g., BDNF, TRKB, and SIM1 deficiencies) and syndromic forms of obesity [e.g., Prader-Willi syndrome (PWS)]. Syndromic obesity arising from chromosomal abnormalities, that typically also affect learning and development, are often associated with congenital malformations and behavioral characteristics. We report on nine unrelated patients with a diagnosis of learning disability and/or developmental delay (DD) in addition to obesity that were found to have copy number variants (CNVs) by single nucleotide polymorphism array-based analysis. Each patient also had a distinct and complex phenotype, and most had hypotonia and other neuroendocrine issues, such as hyperphagia and hypogonadism. Molecular and clinical characterization of these patients enabled us to determine with confidence that the CNVs we observed were pathogenic or likely to be pathogenic. Overall, the CNVs reported here encompassed a candidate gene or region (e.g., SIM1) that has been reported in patients associating obesity and DD and/or intellectual disability (ID) and novel candidate genes and regions.

A scoping review of weight bias by community pharmacists towards people with obesity and mental illness.

PubMed

Murphy, Andrea L; Gardner, David M

2016-07-01

Community pharmacists are accessible health care professionals who are increasingly offering weight management programs. People living with serious mental illness have markedly higher rates of obesity and associated illness outcomes than the general population, providing pharmacists who are interested in offering weight management services with an identifiable patient subgroup with increased health needs. Issues with stigma within obesity and mental illness care are prevalent and can lead to inequities and reduced quality of care. We conducted a scoping review to map and characterize the available information from published and grey literature sources regarding community pharmacists and weight bias towards obese people with lived experience of mental illness. A staged approach to the scoping review was used. Six articles and 6 websites were abstracted after we removed duplicates and applied our inclusion and exclusion criteria. The published studies that we found indicated that pharmacists and pharmacy students do demonstrate implicit and explicit weight bias. Very limited research is available regarding weight bias in pharmacists and stigma towards people with obesity, and we found no information on these phenomena relating to people with lived experience of mental illness. Investigations are needed to characterize the extent and nature of anti-fat bias and attitudes by pharmacists and the consequences of these attitudes for patient care.

Is it acceptable to use animals to model obese humans? A critical discussion of two arguments against the use of animals in obesity research.

2014-05-01

Animal use in medical research is widely accepted on the basis that it may help to save human lives and improve their quality of life. Recently, however, objections have been made specifically to the use of animals in scientific investigation of human obesity. This paper discusses two arguments for the view that this form of animal use, unlike some other forms of animal-based medical research, cannot be defended. The first argument leans heavily on the notion that people themselves are responsible for developing obesity and so-called 'lifestyle' diseases; the second involves the claim that animal studies of obesity's causes and therapies distract attention from preventive efforts. Drawing on both empirical data and moral reasoning, we argue that the relevant attributions of responsibility and claims about distraction are not plausible, and that, therefore, there is no reason to single out the use of animals in obesity research as especially problematic.

2009-01-01

Rural youth are at greater risk than urban youth for obesity and physical inactivity. Active living research incorporates an ecological approach to promoting physical activity (PA) by recognizing that individual behavior, social environments, physical environments, and policies contribute to behavior change. Active living research and interventions have been limited primarily to urban settings. Because rural communities have unique environmental features and sociocultural characteristics, this project combines insights from current active living models with more focused consideration of the physical and social realities of rural areas. In this study, we report on our efforts to develop, test, and refine a conceptual model describing the interaction between the individual and the environment as it enhances or thwarts active living in rural communities. Our findings revealed a host of relevant "predisposing" and "enabling" factors, including sociodemographic, environmental, policy, and programmatic elements, that extend across the four domains of active living--transportation, recreation, occupation, and household. A one-size approach to PA promotion will not fit the needs of rural youth. Given the unique challenges that rural communities face, efforts to combat childhood obesity must consider rural residents a priority population. More research, interventions, and evaluations on ways to promote rural PA are needed.

To investigate whether the gender gap in obesity prevalence is greater among U.S. blacks than whites in a study designed to account for racial differences in socioeconomic and environmental conditions. We estimated age-adjusted, race-stratified gender gaps in obesity (% female obese - % male obese, defined as body mass index ≥30 kg/m(2)) in the National Health Interview Survey 2003 and the Exploring Health Disparities in Integrated Communities-Southwest Baltimore 2003 study (EHDIC-SWB). EHDIC-SWB is a population-based survey of 1381 adults living in two urban, low-income, racially integrated census tracts with no race difference in income. In the National Health Interview Survey, the obesity gender gap was larger in blacks than whites as follows: 7.7 percentage points (ppts; 95% confidence interval (CI): 3.4-11.9) in blacks versus -1.5 ppts (95% CI: -2.8 to -0.2) in whites. In EHDIC-SWB, the gender gap was similarly large for blacks and whites as follows: 15.3 ppts (95% CI: 8.6-22.0) in blacks versus 14.0 ppts (95% CI: 7.1-20.9) in whites. In a racially integrated, low-income urban community, gender gaps in obesity prevalence were similar for blacks and whites. Copyright © 2015 Elsevier Inc. All rights reserved.

To calculate the prevalence of maternal obesity and to determine the relation between obesity and cesarean delivery in an urban hospital in Djibouti. In an observational cohort study, all women who had a live birth or stillbirth between October 2012 and November 2013 were considered for inclusion. Body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) was calculated throughout pregnancy, and women with a BMI of at least 30.0 were deemed to be obese. Multivariate logistic regression analyses were used to evaluate the relation between cesarean and obesity. Overall, 100 (24.8%) of 404 women were obese before 14 weeks of pregnancy, as were 112 (25.2%) of 445 before 22 weeks, and 200 (43.2%) of 463 at delivery. Obesity before 22 weeks was associated with a 127% excess risk of cesarean delivery (adjusted odds ratio 2.27; 95% CI 1.07-4.82; P=0.032). Similar trends were found when the analyses were limited to the subgroup of women without a previous cesarean delivery or primiparae. Prevalence of maternal obesity is high in Djibouti City and is related to an excess risk of cesarean delivery, even after controlling for a range of medical and socioeconomic variables.

Overweight and obesity lead to higher probability of individuals accessing primary care but adiposity estimates are rarely available at regional levels to inform health service planning. This paper analyses a large, community-derived clinical database of objectively measured body mass index (BMI) to explore relationships with area-level socioeconomic disadvantage for informing regional level planning activities. The study included 91776 adults who had BMI objectively measured between 1 July 2009 and 30 June 2011 by a single pathology provider. Demographic data and BMI were extracted and matched to 2006 national census socioeconomic data using geocoding. Adjusted odds-ratios for overweight and obesity were calculated using sex-stratified logistic regression models with socioeconomic disadvantage of census collection district of residence as the independent variable. The prevalence of overweight or obesity was 79.2% (males) and 65.8% (females); increased with age to 74 years; and was higher in rural (74%) versus urban areas (71.4%) (p<0.001). Increasing socioeconomic disadvantage was associated with increasing prevalence of overweight (p<0.0001), obesity (p<0.0001) and overweight or obesity (p<0.0001) in women and obesity (p<0.0001) in men. Socioeconomic disadvantage was unrelated to overweight (p = 0.2024) and overweight or obesity (p = 0.4896) in males. It is feasible to link routinely-collected clinical data, representative of a discrete population, with geographic distribution of disadvantage, and to obtain meaningful area-level information useful for targeting interventions to improve population health. Our results demonstrate novel area-level socioeconomic gradients in overweight and obesity relevant to regional health service planning.

African American adolescent females have the highest prevalence rates of obesity among those age 18 and under. The long-term health effects and associated comorbidities of obesity within this cohort threaten the health and well-being of a major section of the U.S. population. There is a need to understand the influence of parental support in reducing obesity related health disparities. Using a social ecological framework to explore parental influence on adolescent obesity interventions allows for greater insight into the complex and dynamic influences affecting the lives of African American adolescent females who are obese.

This study aims to determine the frequency of behaviour change and related factors generated in the population through the "Fighting Obesity Campaign" of the Turkish Ministry of Health. Twelve statistical regions from NUTS-1 and 18 provinces were selected for the study sample. At least one province from each region was randomly selected, and stratawere defined as urban or rural. Of the sample selected, 2,038 respondents completed a face-to-face survey. Logistic regression analysis was used to analyse the data. Changing behaviour as result of the campaign was defined as the dependent variable. Behaviour change was defined as an individual taking at least one action to increase physical activity, calculate her/his Body Mass Index (BMI) or minimise meal portions. Of the sample selected, 84% of participants lived in urban areas. Of total sample selected, 49.8% were men and 50.2% were women. According to BMI categorisation, 41.4% of participants were underweight or normal weight, 34.3% were overweight and 24.3% were obese. Of the total participants, 85.2% learned about the "Fighting-Obesity Campaign" through television, 28.1% through radio, 11.0% from newspapers, 6.0% from billboards, and 19.2% from other sources. This study revealed that 28.5% of the participants adopted desired behavioural changes after exposure to the campaign. Logistic regression results demonstrated that behaviour change is greater among women, individuals living in urban settings, group of persons approving public spots, obese individuals, and among the 20-39 age group. Media campaigns may cause behavioural changes by increasing motivation to prevent obesity within the target population. Con- tinuing these campaigns can lead to success at the national level.

[Psychological consequences of obesity].

Müller, Roland

2013-02-01

Overweight and obesity is associated with a broad variety of stigmatization and discrimination in every day live. Obese people have more difficulties in finding a job, have a lower income, and are less often seen in leadership positions. In society, responsibility for the weight situation in seen as lying by the individuals affected altogether, leading to chronic stress, problems with self esteem and perception of loss of control. As a consequence, there is an increased risk for developing serious psychological problems such as affective and anxiety disorders. As a reaction, coping strategies to deal with the psychological pressure such as dysfunctional eating behavior, binge eating and physical inactivity are used. Females, people belonging to another ethnic or social minority, adolescents and people with eating disorders are considered at increased risk of psychological distress. Psychological vulnerabilities and the consequences of stigmatization need to be considered. Moreover, perceived behavioral control and self esteem are key aspects of to be addressed on the treatment.

Food Retailers and Obesity.

PubMed

Stanton, Rosemary A

2015-03-01

We live in an 'obesogenic environment' where we are constantly bombarded with choices that encourage us to move less and eat more. Many factors influence our dietary choices, including the expert marketers who advise manufacturers on ways to encourage the population to buy more, especially profitable, palatable 'ultra-processed' foods. Supermarkets themselves have become skilled in manipulating buying behaviour, using their layout and specific product placement as well as advertising to maximise purchases of particular foods. Increasingly, supermarkets push their own 'house' brands. Those marketing fast foods also use persuasive tactics to attract customers, especially children who they entice with non-food items such as promotional or collectable toys. There is no mystery to the increase in obesity: our energy intake from foods and drinks has increased over the same period that energy output has decreased. Obesity has a range of relevant factors, but there is little doubt that marketing from supermarkets and fast food retailers has played a role.

In the context of a worldwide obesity epidemic, healthcare providers play a key role in obesity management. Knowledge of current guidelines and attitudes to prevent stigmatization are especially important. This study aimed to assess knowledge, attitudes, beliefs, perception of opportunity for intervention, declared practices and need for training and material of nurses and physicians about obesity in a Swiss University Hospital. A total of 834 physicians and nurses filled an online survey. The questionnaire was based on literature, exploratory interviews and expert committee review. It was pre-tested with 15 physicians and nurses. Participants declared a low level of negative attitudes towards individuals living with obesity. However, the results highlighted a lack of knowledge to diagnose obesity in adults and children, as well as confidence and training to care of patients with obesity. One-third of providers did not know how to calculate body mass index. Half of providers felt it was part of their role to take care of patients with obesity, even if 55% of them had the feeling that they did not have adequate training. Nurses and physicians working in a university hospital showed a low level of negative attitudes but a lack of knowledge and skills on obesity management. Training should be improved in this population to insure adequate and coherent messages and equal access to evidence-based treatment for patients living with obesity. © 2018 World Obesity Federation.

Fingerprinting of HLA class I genes for improved selection of unrelated bone marrow donors.

The degree of matching of HLA genes between the selected donor and recipient is an important aspect of the selection of unrelated donors for allogeneic bone marrow transplantation (UBMT). The most sensitive methods currently used are serological typing of HLA class I genes, mixed lymphocyte culture (MLC), IEF and molecular genotyping of HLA class II genes by direct sequencing of PCR products. Serological typing of class I antigenes (A, B and C) fails to detect minor differences demonstrated by direct sequencing of DNA polymorphic regions. Molecular genotyping of HLA class I genes by DNA analysis is costly and work-intensive. To improve compatibility between donor and recipient, we have set up a new rapid and non-radioisotopic application of the 'fingerprinting PCR' technique for the analysis of the polymorphic second exon of the HLA class I A, B and C genes. This technique is based on the formation of specific patterns (PCR fingerprints) of homoduplexes and heteroduplexes between heterologous amplified DNA sequences. After an electrophoretic run on non-denaturing polyacrylamide gel, different HLA class I types give allele-specific banding patterns. HLA class I matching is performed, after the gel has been soaked in ethidium bromide or silver-stained, by visual comparison of patients' fingerprints with those of donors. Identity can be confirmed by mixing donor and recipient DNAs in an amplification cross-match. To assess the technique, 10 normal samples, 22 related allogeneic bone marrow transplanted pairs and 10 unrelated HLA-A and HLA-B serologically matched patient-donor pairs were analysed for HLA class I polymorphic regions. In all the related pairs and in 1/10 unrelated pairs, matched donor-recipient patterns were identified. This new application of PCR fingerprinting may confirm the HLA class I serological selection of unrelated marrow donors.

Eating styles in the morbidly obese: restraint eating, but not emotional and external eating, predicts dietary behaviour.

Brogan, Amy; Hevey, David

2013-01-01

The research explored (1) the relationships between self-reported eating style (restraint, emotional and external eating) and dietary intake and (2) emotional eater status as a moderator of food intake when emotional, in a morbidly obese population. A sample of 57 obese participants (BMI: M = 51.84, SD = 8.66) completed a five-day food diary together with a reflective diary, which assessed eating style and positive and negative affect daily. A dietician-scored food pyramid analysis of intake. Restraint eating was the only predictor (negative) of overall food intake and the variable most strongly associated with the consumption of top-shelf foods. Emotional and external eating were unrelated to food intake. Emotional eater status did not moderate food intake in response to positive and negative mood states. The findings indicated largely analogous relationships between eating style and dietary intake in this obese sample compared with previous results from healthy populations. The lack of predictive validity for emotional eating scales (when emotional) raises questions over people's ability to adequately assess their eating style and consequently, the overall validity of emotional eater scales.

Alternative allogeneic donor sources for transplantation for childhood diseases: unrelated cord blood and haploidentical family donors.

Allogeneic stem cell transplantation has been demonstrated to be curative in a wide variety of pediatric malignant and nonmalignant diseases, and can be traced back over 50 years ago to the original report of Thomas et al. HLA matched sibling donors have been the gold standard for pediatric recipients requiring allogeneic donors for both nonmalignant and malignant conditions. However, only 25% of potential pediatric recipients possesses an HLA-matched sibling donor, and the frequency is even less in those with genetic nonmalignant conditions because of genetically affected other siblings within the family. Therefore, 75% to 90% of potential pediatric recipients require alternative allogeneic donor cells for treatment of their underlying conditions. Potential alternative allogeneic donor sources include unrelated cord blood donors, unrelated adult donors, and haploidentical family donors. In this article we review the experience of both unrelated cord blood donor and haploidentical family donor transplants in selected pediatric malignant and nonmalignant conditions.

Socio-economics, food habits and the prevalence of childhood obesity in Spain.

PubMed

Gil, J M; Takourabt, S

2017-03-01

In 2012, the prevalence of obesity and overweight statuses among children in Spain was 9% and 26%, respectively. Concerns about childhood obesity have increased over the past few years, as obesity developed during childhood can persist throughout an individual's lifetime (cohort effect). This study aims to develop a better understanding of the factors influencing the prevalence of obesity in Spain. Microdata from the 2012 National Health Survey are used, and the methodological framework is based on the estimation of a sample selection model. Results suggest that the prevalence of obesity increases among children who live in households of a lower socio-economic status and households in which parents are obese. Lower levels of childhood physical activity are positively related to the probability of being obese. Finally, there exists a positive relationship between children's body mass index and an inappropriate intake of fresh fruits, fish, pasta and rice, legumes, sweets and soft drinks. The methodological framework used in this study is flexible enough to be used in traditional longitudinal studies. Children's and households' lifestyles play a pivotal role in the prevalence of obesity. Policies should be oriented toward changing lifestyles, which would require more multidisciplinary research in the future to reduce childhood obesity. © 2016 John Wiley & Sons Ltd.

Previous efforts to forecast future trends in obesity applied linear forecasts assuming that the rise in obesity would continue unabated. However, evidence suggests that obesity prevalence may be leveling off. This study presents estimates of adult obesity and severe obesity prevalence through 2030 based on nonlinear regression models. The forecasted results are then used to simulate the savings that could be achieved through modestly successful obesity prevention efforts. The study was conducted in 2009-2010 and used data from the 1990 through 2008 Behavioral Risk Factor Surveillance System (BRFSS). The analysis sample included nonpregnant adults aged ≥ 18 years. The individual-level BRFSS variables were supplemented with state-level variables from the U.S. Bureau of Labor Statistics, the American Chamber of Commerce Research Association, and the Census of Retail Trade. Future obesity and severe obesity prevalence were estimated through regression modeling by projecting trends in explanatory variables expected to influence obesity prevalence. Linear time trend forecasts suggest that by 2030, 51% of the population will be obese. The model estimates a much lower obesity prevalence of 42% and severe obesity prevalence of 11%. If obesity were to remain at 2010 levels, the combined savings in medical expenditures over the next 2 decades would be $549.5 billion. The study estimates a 33% increase in obesity prevalence and a 130% increase in severe obesity prevalence over the next 2 decades. If these forecasts prove accurate, this will further hinder efforts for healthcare cost containment. Copyright © 2012 Elsevier Inc. All rights reserved.

GROWING UP IN PORTUGAL: CAPE VERDEAN ANCESTRY CHILDREN EXHIBIT LOW OVERWEIGHT AND OBESITY COMPARED WITH PORTUGUESE IN URBAN LISBON.

Portugal has one of the highest rates of childhood overweight and obesity in Europe. However, little is known about the health of ethnic minorities living in its capital city, Lisbon. The Cape Verdean community in Lisbon tend to have low educational levels, material deprivation and struggle with discrimination and racism, factors that would probably be associated with a higher prevalence of overweight and obesity. Data for the Cape Verdean population were collected in three different time periods by three different research teams in 1993, 2009 and 2013 and included children aged 6-12 years living in the Cova da Moura neighbourhood of the Greater Lisbon Metro Area. The Portuguese national survey was conducted between 2009 and 2010 at public and private schools in mainland Portugal and included height, weight, skinfolds and arm and waist circumferences. From these survey data body mass index (BMI) and prevalence of stunting (chronic malnutrition - low height-for-age) and underweight (low weight-for-age) were calculated according to reference values proposed by Frisancho (2008). Overweight and obesity prevalence values were defined based on the references established by the International Obesity Task Force. The results show significant differences in height between Cape Verdean and Portuguese boys and girls. Generally, Cape Verdeans' growth falls within the healthy range of international growth references across all of the survey data collected. Cape Verdean rates for combined overnutrition (overweight and obesity) in 2013 (9.8% for boys and 16.7% for girls) were lower than those of the Portuguese (33% for boys and 31.7% for girls). Logistic regression models showed that Cape Verdean children had a lower risk of being overweight or obese when accounting for breast-feeding, birth weight, maternal education and occupation. Despite living in a deprived neighbourhood these Cape Verdean children seemed to have grown more healthily than Portuguese ancestry children. The

In recent years, there has been a paralleled increase between male obesity and infertility rates. Obesity is associated with impaired hypothalamic-pituitary-gonadal axis, aberrant semen parameters, and subfertility or infertility. Weight loss is strongly recommended for the management of obesity-associated infertility. Lifestyle modifications that include caloric restriction and increased physical activity have a short-lived impact. Bariatric surgery is a better and more durable weight loss alternative. Comprehensive information about the benefits of weight loss on obesity-associated male infertility following bariatric surgery is still emerging. In this review, we discuss the hormonal, physical and environmental mechanism contributing to obesity-associated infertility. We then assess weight loss approaches, which include lifestyle modification, medical and surgical approaches, that can improve fertility in obese men. This review focuses also on bariatric surgery for the management of obese men seeking fertility treatment. Anecdotal evidence suggesting that bariatric surgery can impair fertility is also discussed.

While neighborhood environments are increasingly recognized as important contributors to obesity risk, less has been reported on the socio-cultural aspects of neighborhoods that influence obesity development. This is especially true among immigrants, who may lack the necessary language skills to navigate their new living environments. In this study, we tested the hypothesis that young children of immigrants would be at lower obesity risk if they lived in neighborhoods where neighbors share the same language and culture. Using 2000 Census data and 2003-2009 data from the Special Supplemental Nutrition Program for Women, Infants and Children in Los Angeles County, we examined the relation between BMI z-scores in low-income children aged 2-5 years (N = 250,029) and the concentration of neighborhood residents who spoke the same language as the children's mothers. Using multi-level modeling and adjusting for child's gender and race/ethnicity, household education, neighborhood socioeconomic status, and year the child was examined, we found that percent of neighborhood residents who spoke the same language as the child's mother was negatively associated with BMI z-scores. This relation varied by child's race/ethnicity and mother's preferred language. The relation was linear and negative among children of English-speaking Hispanic mothers and Chinese-speaking mothers. However, for Hispanic children of Spanish-speaking mothers the relation was curvilinear, initially exhibiting a positive relation which reversed at higher neighborhood concentrations of Spanish-speaking residents. Our findings suggest that living in neighborhoods where residents share the same language may influence obesity-related behaviors (namely diet and physical activity) possibly through mechanisms involving social networks, support, and norms.

Large registries of potential unrelated stem cell donors have been established in order to enable stem cell transplantation for patients without HLA-identical related donors. Donor search is complicated by the fact that the stored HLA information of many registered donors is incomplete. We carried out a project that was aimed to improve chances of patients with ongoing donor searches to find an HLA-matched unrelated donor. For that purpose, we carried out additional donor center-initiated HLA-DRB1 typing of donors who were only typed for the HLA loci A and B so far and were potential matches for patients in need of a stem cell transplant. In total, 8,861 donors were contacted for donor center-initiated HLA-DRB1 typing within 1,089 donor searches. 12 of these donors have donated stem cells so far, 8 thereof for their respective target patients. We conclude that chances of patients with ongoing donor searches to find an HLA-matched unrelated donor can indeed be improved by donor-center initiated typing that is carried out in addition to the standard donor search process. Our results also raise questions regarding the appropriate use of incompletely typed donors within unrelated donor searches. PMID:21625451

Using a large social media database, Yahoo Answers, we explored postings to an online forum in which posters asked whether their height and weight qualify themselves as "skinny," "thin," "fat," or "obese" over time and across forum topics. We used these data to better understand whether a higher-than-average body mass index (BMI) in one's county might, in some ways, be protective for one's mental and physical health. For instance, we explored whether higher proportions of obese people in one's county predicts lower levels of bullying or "am I fat?" questions from those with a normal BMI relative to his/her actual BMI. Most women asking whether they were themselves fat/obese were not actually fat/obese. Both men and women who were actually overweight/obese were significantly more likely in the future to ask for advice about bullying than thinner individuals. Moreover, as mean county-level BMI increased, bullying decreased and then increased again (in a U-shape curve). Regardless of where they lived, posters who asked "am I fat?" who had a BMI in the healthy range were more likely than other posters to subsequently post on health problems, but the proportions of such posters also declined greatly as county-level BMI increased. Our findings suggest that obese people residing in counties with higher levels of BMI may have better physical and mental health than obese people living in counties with lower levels of BMI by some measures, but these improvements are modest.

On the role of attention and emotion in morality: attentional control modulates unrelated disgust in moral judgments.

PubMed

Van Dillen, Lotte F; van der Wal, Reine C; van den Bos, Kees

2012-09-01

The emotion of disgust can influence people's moral judgments, even if this emotion objectively is unrelated to the moral judgment in question. The present work demonstrates that attentional control regulates this effect. In three studies, disgust was induced. In an unrelated part of the studies, participants then judged a moral transgression. Disgust resulted in more severe moral judgments when attentional control (either measured by means of individual predisposition or manipulated with experimental control) was weak as opposed to strong (Studies 1-3). Findings further showed that attentional control mediated the positive relation between the intensity of participants' disgust responses and the severity of their moral judgments (Study 2). Moreover, attentional control has its effects through the regulation of affective processing (Study 3). Taken together, the findings suggest that unrelated influences of disgust on moral judgments are contingent on the attention system.

SCN is an inherited hematological disorder with severe neutropenia and recurrent infections. Although there are some reports that recombinant rhG-CSF improves clinical outcome, allogeneic HSCT appears to be the only curative treatment for these patients. We report here two children with SCN successfully treated by CBT from unrelated donors. They were refractory to rhG-CSF treatment and have no identical family donor. Bu + CY were given as conditioning. Case 1 and Case 2 received 6/6 and 5/6 HLA-matched unrelated umbilical cord blood, respectively. The number of infused nucleated cells was 6, 18 x 10(7)/kg and CD34(+) cell number was 3, 74 x 10(5)/kg in Case 1. Those cell numbers were 8, 8 x 10(7)/kg and 5, 34 x 10(5)/kg for Case 2, respectively. Neutrophil/platelet engraftments were 45/49 days in Case 1 and 24/36 days in Case 2. Grade II cutaneous acute GVHD was seen in Case 2 that was treated successfully with prednisolone. Both patients are well with normal hematological findings and full donor chimerism for post-transplant 20 and 24 months, respectively. We conclude that UCB can be considered as a safe source of stem cell in patients with SCN who need urgent HSCT.

Objective Self-stigma in overweight and obese individuals has strong associations with impairment in mental and global health. This study sought to explore self-compassion as a psychological resource in the self-stigma process. Methods In a 2012 representative German population survey of N = 1,158 overweight and obese individuals, self-compassion was examined as a mediator between self-stigma and mental and physical health outcomes, including BMI (kg/m2), using structural equation modeling and controlling for sociodemographic factors. Results Psychological variables were assessed using validated self-report questionnaires. Self-compassion partially mediated the relationships between self-stigma and depression, somatic symptoms, and health status / quality of life, lowering the predictive effect of self-stigma on the outcomes by approximately one-third. In contrast, self-compassion, because it was unrelated to BMI, did not mediate the association between self-stigma and BMI. Conclusion Self-compassion has the potential to act as a buffer against the mental and global health detriments of self-stigma in overweight and obesity and could thus represent a target for interventions to reduce self-stigma and prevent these health impairments. In order to influence the association between self-stigma and BMI, self-compassion should conceptually be linked to weight management. PMID:26422226

Circulating Irisin Levels Are Not Regulated by Nutritional Status, Obesity, or Leptin Levels in Rodents.

2015-01-01

Irisin is a cleaved and secreted fragment of fibronectin type III domain containing 5 (FNDC5) that is mainly released by skeletal muscle and was proposed to mediate the beneficial effects of exercise on metabolism. In the present study we aim to investigate the regulation of the circulating levels of irisin in obese animal models (diet-induced obese (DIO) rats and leptin-deficient (ob/ob) mice), as well as the influence of nutritional status and leptin. Irisin levels were measured by Enzyme-Linked Immunosorbent Assay (ELISA) and Radioimmunoassay (RIA). Serum irisin levels remained unaltered in DIO rats and ob/ob mice. Moreover, its circulating levels were also unaffected by fasting, leptin deficiency, and exogenous leptin administration in rodents. In spite of these negative results we find a negative correlation between irisin and insulin in DIO animals and a positive correlation between irisin and glucose under short-term changes in nutritional status. Our findings indicate that serum irisin levels are not modulated by different physiological settings associated to alterations in energy homeostasis. These results suggest that in rodents circulating levels of irisin are not involved in the pathophysiology of obesity and could be unrelated to metabolic status; however, further studies should clarify its precise role in states of glucose homeostasis imbalance.

Perceived Environmental Factors Associated with Obesity in Libyan Men and Women

Papadopoulos, Chris

2018-01-01

Background: There is a lack of research pertaining to the links between built environment attributes and obesity in adults in the Eastern Mediterranean Region. In the Libyan context, no previous studies have been conducted to investigate this relationship. Therefore, the aim of this study was to examine associations between perceived neighbourhood built environmental attributes and obesity among Libyan men and women. The prevalence of overweight and obesity was also assessed. Methods: A cross-sectional study design was used for the population-based survey in Benghazi, Libya. A multi-stage cluster sampling technique was used to select Libyan adults from the Benghazi electoral register. The Physical Activity Neighbourhood Environment Scale (PANES) was used to measure participants’ perception of neighbourhood environmental factors. Using the Tanita BC-601 Segmental Body Composition Monitor and a portable stadiometer, anthropometric measurements were taken at a mutually agreeable place by qualified nurses. Results: Four hundred and one Libyan adults were recruited (78% response rate). Participants were aged 20–65 years, 63% were female, and all had lived in Benghazi for over 10 years. The prevalence of obesity and overweight was 42.4% and 32.9% respectively. A significant association was found between BMI and 6 neighbourhood environment attributes, specifically: street connectivity, unsafe environment and committing crimes at night, and neighbourhood aesthetics. For men only, these were: access to public transport, access to recreational facilities, and unsafe environment and committing crimes during the day. The attribute ‘residential density zones’ was only significant for women. Conclusions: The study suggests that Libyan people are at risk of living in neighbourhoods with unsupportive environmental features of physical activity, which are likely to promote obesity of both genders. The findings of this study could inform Libyan health policies about

Childhood-Adolescent Obesity in the Cardiorenal Syndrome: Lessons from Animal Models

Hayden, Melvin R.; Sowers, James R.

2011-01-01

Background/Aims Childhood-adolescent overweight and obesity have grown to pandemic proportions during the past decade. The onset of obesity in younger adults will likely be manifested as earlier onset of myocardial and renal end-organ disease in younger adults. For the first time, it is estimated that the current generation may not live to be as old as their parents. Thus, it is important to develop animal models of childhood obesity to understand fundamental pathological organ changes. Methods In this regard, we utilize transmission electron microscopy evaluation to evaluate early remodeling changes of two adolescent rodent obesity models: the Zucker obese (fa/fa) rat and the db/db mouse models of obesity. We have concentrated on the initial ultrastructural remodeling (obese adipose tissue, skeletal muscle, and islet remodeling) and the associated changes in target end organs (including the myocardium and kidney) in young rodent models of obesity and insulin resistance, collectively manifesting as the cardiorenal metabolic syndrome (CRS). Results Briefly, tissues revealed the following ultrastructural remodeling abnormalities: inflammation, hypertrophy, and early fibrosis in adipose tissue; loss of mitochondria in skeletal muscles, hyperplasia, fibrosis, and depletion of insulin-secretory granules in pancreatic islets; increased intramyocardial lipid accumulation, fibrosis, and mitochondrial deposition in the myocardium, and obesity-related glomerulopathy and tubulopathy in the kidney. Conclusion Based on the current knowledge and ultrastructural observations of organ pathology, we propose mechanisms whereby obesity appears to be the driving force behind the development of the CRS.

Limited data exist regarding the association between binge eating and quality of life (QOL) in obese adolescent girls and boys. We, therefore, studied binge eating and QOL in 158 obese (BMI ≥ 95th percentile) adolescents (14.5 ± 1.4 years, 68.0% female, 59% African-American) prior to weight-loss treatment. Youth completed an interview to assess binge eating and a questionnaire measure of QOL. Controlling for body composition, binge eating youth (n = 35), overall, reported poorer QOL in domains of health, mobility, and self-esteem compared to those without binge eating (ps < 0.05). Also, girls, overall, reported poorer QOL than boys in activities of daily-living, mobility, self-esteem, and social/interpersonal functioning (ps < 0.05). Girls with binge eating reported the greatest impairments in activities of daily living, mobility, self-esteem, social/interpersonal functioning, and work/school QOL (ps < 0.05). Among treatment-seeking obese adolescents, binge eating appears to be a marker of QOL impairment, especially among girls. Prospective and treatment designs are needed to explore the directional relationship between binge eating and QOL and their impact on weight outcomes. PMID:22666544

What is the cost-effectiveness of lifestyle intervention preceding infertility treatment in obese infertile women? Lifestyle intervention preceding infertility treatment as compared to prompt infertility treatment in obese infertile women is not a cost-effective strategy in terms of healthy live birth rate within 24 months after randomization, but is more likely to be cost-effective using a longer follow-up period and live birth rate as endpoint. In infertile couples, obesity decreases conception chances. We previously showed that lifestyle intervention prior to infertility treatment in obese infertile women did not increase the healthy singleton vaginal live birth rate at term, but increased natural conceptions, especially in anovulatory women. Cost-effectiveness analyses could provide relevant additional information to guide decisions regarding offering a lifestyle intervention to obese infertile women. The cost-effectiveness of lifestyle intervention preceding infertility treatment compared to prompt infertility treatment was evaluated based on data of a previous RCT, the LIFEstyle study. The primary outcome for effectiveness was the vaginal birth of a healthy singleton at term within 24 months after randomization (the healthy live birth rate). The economic evaluation was performed from a hospital perspective and included direct medical costs of the lifestyle intervention, infertility treatments, medication and pregnancy in the intervention and control group. In addition, we performed exploratory cost-effectiveness analyses of scenarios with additional effectiveness outcomes (overall live birth within 24 months and overall live birth conceived within 24 months) and of subgroups, i.e. of ovulatory and anovulatory women, women <36 years and ≥36 years of age and of completers of the lifestyle intervention. Bootstrap analyses were performed to assess the uncertainty surrounding cost-effectiveness. Infertile women with a BMI of ≥29 kg/m2 (no upper limit) were

This paper empirically examines the effect of parents' and individuals' own socioeconomic status on overweight and obesity, and investigates how this effect changes over the life cycle. The impact of individuals' health behaviours on their obesity status later in life is also studied. We use data from Denmark, Finland, France, Greece, the Netherlands and the U.K. in which 4595 individuals aged 50-65 are surveyed and where individuals' height and weight at different ages (25, 35, 45 and current age) are available. We perform "repeated cross-sections" analyses as well as dynamic probit analyses of the individuals' obesity histories. We contribute to the literature by examining the role of a variety of obesity determinants over the whole life cycle, not only over a certain portion of individuals' lives. Key findings are: (i) parents' socioeconomic status predicts obesity in early adulthood whereas the individual's own socioeconomic status as adult is more important in explaining obesity at later stages of the life cycle, (ii) changes in obesity status are associated with changes in health behaviours, (iii) obesity in late adulthood is strongly and positively correlated with overweight and obesity in younger ages, and (iv) cross-country differences in obesity and overweight largely remain after controlling for parental and childhood factors and individuals' health behaviours.

We used cross-sectional data on 2,660 black and 2,611 Mexican-American adult participants in the National Health and Nutrition Examination Survey (1999–2006) to investigate the association between metropolitan-level racial/ethnic residential segregation and obesity and to determine whether it was mediated by the neighborhood socioeconomic environment. Residential segregation was measured using the black and Hispanic isolation indices. Neighborhood poverty and negative income incongruity were assessed as mediators. Multilevel Poisson regression with robust variance estimates was used to estimate prevalence ratios. There was no relationship between segregation and obesity among men. Among black women, in age-, nativity-, and metropolitan demographic-adjusted models, high segregation was associated with a 1.29 (95% confidence interval (CI): 1.00, 1.65) times higher obesity prevalence than was low segregation; medium segregation was associated with a 1.35 (95% CI: 1.07, 1.70) times higher obesity prevalence. Mexican-American women living in high versus low segregation areas had a significantly lower obesity prevalence (prevalence ratio, 0.54; 95% CI: 0.33, 0.90), but there was no difference between those living in medium versus low segregation areas. These associations were not mediated by neighborhood poverty or negative income incongruity. These findings suggest variability in the interrelationships between residential segregation and obesity for black and Mexican-American women. PMID:23337312

Childhood obesity has become a significant problem in the United States, especially in poor communities, and we know that children who have at least 1 obese parent have a much higher risk of being obese. Combined behavioral lifestyle interventions and family-based intervention programs to address pediatric obesity have the strongest evidence of effectiveness. In this pilot study, we delineate our collaborative model of family group medical visits at a community health center combined with healthy living workshops involving families with at least 1 child and 1 parent or guardian who are obese as a unique approach to address obesity in children.

Several studies have documented increased prevalence of overweight and obesity in inhabitants of rural regions, but determinants of their prevalence are complex and not always in one direction. The aim of this study was to estimate both the prevalence and extent of overweight and obesity among rural girls in Poland between 1987 and 2001, as well as to assess differentiation of the phenomenon between regions of different social structures. The data come from two series of cross-sectional studies; the first in 1987 included 7764 girls, and the second in 2001 included 9431 girls aged 9-18. Body mass index (according to the International Obesity Task Force, IOTF) and the EOW index (extent of overweight), which shows by what mean BMI value the overweight boundaries are exceeded, were calculated. Overweight and obesity prevalences in the whole sample, were, respectively, 14.9% and 2.7% in 1987 and 15.5% and 2.5% in 2001, but significant differentiation in the direction of the changes was observed between the examined regions. In one of them, characterized by sudden, mass and long-term unemployment, there was a considerable decrease in overweight and obesity prevalence, whereas in a relatively wealthier region no changes were observed during the 14-year period. Two other regions with a relatively low standard of living and low incomes and education status presented a significant increase in overweight and obesity prevalence. The EOW index increased from 1.9 to 2.1 in the whole examined sample, and it also confirmed significant differences in expansion of overweight and obesity between the examined regions. The complex character of political and socioeconomic changes in Poland during the 1990 s has resulted in two-directional changes in biological measures of living conditions. The analysis of the whole sample led to different results in comparison to separate analyses of each of the examined regions.

Induction therapy is mostly recommended for deceased-donor transplantation, whereas it has some controversies in live-donor transplantation. In this study, we described the outcomes of live-donor renal transplant recipients who received ATG-Fresenius (ATG-F) induction. Live-donor transplantations in patients over 18 years old with ATG-F induction between 2009 and 2015 were included. All patients received quadruple immunosuppression, one of which was ATG-F induction. Biopsies after the artery anastomosis (zero hour) and protocol biopsies at the 6th month and at the 1st first year were obtained. Acute graft dysfunction was defined as a 20% to 25% increase in creatinine level from baseline. All acute rejection episodes were biopsy-confirmed. All episodes were initially treated with intravenous methyl prednisolone (MP) or ATG-F if resistant to MP. Four hundred twenty-two patients with live-donor transplantation were evaluated. The mean age was 40 ± 13 (18-73) years. The mean panel-reactive antibody levels were 42% ± 30% and 45% ± 30% for class I and II, respectively. The mean mismatch number for living unrelated donors (n = 112) was 4.6 ± 1.0. Acute rejection rate was 29.1% (123 patients) within the first year. The mean cumulative ATG-F doses for per patient and per kilogram were 344 ± 217 mg and 5.1 ± 2.7 mg, respectively. Patient survival rates were 98.3% and 96.7% for 12 months and 60 months, respectively. Death-censored graft survival rates were 97.6% and 92.1% for 12 months and 60 months, respectively. ATG-F induction provided excellent graft and patient survival rates without any significantly increased side effects. Increasing sensitized patient numbers, more unrelated donors, increasing re-transplantation numbers, and more desensitization protocols make ATG-F more favorable in an induction regimen.

Obesity and depression are among the leading causes of disability in Mexico, but their association has not been explored yet. The aim of the current study was to investigate the association between obesity and depression in Mexican population. We used data from the health and nutrition survey (ENSANUT 2012), which is representative of the Mexican population. Obesity was determined using the body mass index (BMI) and abdominal obesity by measuring waist circumference. Depressive symptoms were reported using the Center for Epidemiological Studies Depression Scale Short-Form (CES-D-SF, scale 0-21). Regression analyses were performed between obesity and depression, adjusting for gender, age, living with a partner, education, and diabetes history. Obese women had 1.28 (95% CI 1.07-1.53) times the odds of having depression in comparison with normal-weight women, whereas no association was found for men (OR 0.94; 95% CI 0.74-1.19). A significant association between BMI and depressive symptoms score (β = 0.05, 95% CI 0.02-0.07) was present in women, but no association was found for men (β = - 0.02, 95% CI - 0.05 to 0.00). There was a statistically significant association between waist circumference and depression scores again for women (β = 0.03, 95% CI 0.01-0.04) but not for men (β = 0.00, 95% CI - 0.01 to 0.01). No associations were found between abdominal obesity and depression for both genders. No association was found between different obesity severity levels and depression for both genders. Obesity was associated with depression in Mexican women, whereas no association was found between obesity and depression in men.

Exercise intervention for management of obesity.

Deusinger, Susan S

2012-01-01

Obesity touches the lives of most Americans regardless of age. In adults, accrual of co-morbidities, including frank disability, impacts health in ways that mandate aggressive public health action. In children, the rising prevalence of overweight and obesity raises serious prospective concerns for life as these children enter adulthood. Action is imperative to provide medical interventions and preventive strategies to reduce the threat this condition poses to future generations. Obesity primarily results from an energy regulation imbalance within the body; understanding its origin and effects requires considering both the intake (via eating) and output (via moving) of energy. This article focuses on how exercise and physical activity (i.e., energy output) can influence the primary condition of obesity and its health sequelae. Components, strategies, and expected outcomes of exercise and lifestyle activity are addressed. Successful long-term participation in daily movement requires matching exercise regimens and physical activity outlets to individual preferences and environmental conditions. Activity habits of Americans must change at home and in the workplace, schools and the community to positively influence health. Although the goals of Healthy People 2010 to reduce sedentary behavior have not been met, success of other public health interventions (e.g., immunizations, use of bicycle helmets) suggests that social change to alter activity habits can be achieved. Failure to reach our public health goals should serve as a catalyst for broad-based action to help children, adolescents, and adults attain and maintain behaviors that reduce the risk of obesity and its health insults.

Conceptualizing Obesity as a Chronic Disease: An Interview With Dr. Arya Sharma.

PubMed

Sharma, Arya M; Goodwin, Donna L; Causgrove Dunn, Janice

2018-03-23

Dr. Arya M. Sharma challenges the conventional wisdom of relying simply on "lifestyle" approaches involving exercise, diet, and behavioral interventions for managing obesity, suggesting that people living with obesity should receive comprehensive medical interventions similar to the approach taken for other chronic diseases such as Type 2 diabetes or hypertension. He purports that the stigma-inducing focus on self-failing (e.g., coping through food, laziness, lack of self-regulation) does not address biological processes that make obesity a lifelong problem for which there is no easy solution. Interdisciplinary approaches to obesity are advocated, including that of adapted physical activity. Physical activity has multifaceted impacts beyond increasing caloric expenditure, including improved sleep, better mood, increased energy levels, enhanced self-esteem, reduced stress, and an enhanced sense of well-being. The interview with Dr. Sharma, transcribed from a keynote address delivered at the North American Adapted Physical Activity Symposium on September 22, 2016, in Edmonton, AB, Canada, outlines his rationale for approaching obesity as a chronic disease.

Trends in the Relationship Between Obesity and Disability, 1988-2012.

Rising obesity rates, coupled with population aging, have elicited serious concern over the impact of obesity on disability in later life. Prior work showed a significant increase in the association between obesity and disability from 1988 to 2004, calling attention to disability as a cost of longer lifetime exposure to obesity. It is not known whether this trend has continued. We examined functional impairment and impairment in activities of daily living (ADL) (defined as severe or moderate to severe) for adults aged 60 years or older (n = 16,770) over 3 time periods in the National Health and Nutrition Examination Survey. The relative odds of impairment for obese individuals versus normal-weight individuals significantly increased from period 1 (1988-1994) to period 2 (1999-2004) for all outcomes. In period 3 (2005-2012), this association remained stable for functional and severe ADL impairment and decreased for moderate-to-severe ADL impairment. The fraction of population disability attributable to obesity followed a similar trend. The trend of an increasing association between obesity and disability has leveled off in more recent years, and is even improving for some measures. These findings suggest that public health and policy concerns that obesity would continue to become more disabling over time have not been borne out. © The Author(s) 2017.

Historically in developing countries, the prevalence of obesity has been greater in more advantaged socioeconomic groups. However, in recent years the association between socioeconomic status (SES) and obesity has changed and varies depending on the country’s development stage. This study examines the relationship between SES and obesity using two indicators of SES: education or possession assets. Using the cross-sectional 2008 National Demographic and Family Health Survey of Peru (ENDES 2008) we investigated this relationship in women aged 15 to 49 years living in rural and urban settings. Descriptive, linear and logistic regressions analyses were conducted accounting for the multi-staged nature of the sampling design. The overall prevalence of obesity in this study was 14.1% (95%CI: 13.3–14.8); 8.4% (95%CI: 7.5–9.3) in rural areas and 16.2% (95%CI: 15.2–17-2) in urban areas. Wealthier women were more likely to be obese, and this association was stronger in rural areas. Conversely, more educated women were less likely to be obese, especially in urban areas. The distribution of obesity in Peruvian women is strongly related to socioeconomic position, and differs whether measured as possession assets or by level of education. These findings could have important implications for policy development in Peru. PMID:21959344

The tyranny of the gift: sacrificial violence in living donor transplants.

Scheper-Hughes, N

2007-03-01

Medical anthropology can bring to living donor transplant useful insights on the nature of gifting, family obligations, reciprocity and invisible sacrifice. Whereas, ethical reflections and debates on the marketing of tissues and organs, especially sales by living strangers, have proliferated to the point of saturation, the larger issue of the ethics of "altruistic" donation by and among family members is more rarely the focus of bio-ethical scrutiny and discussion today, though of course it was much debated in the early decades of kidney transplant. As the proportion of living over deceased donors (especially of kidneys) has increased markedly in the past decade, the time is ripe to revisit the topic, which I shall do via three vignettes, all of them informed by my 10 years as founding Director of Organs Watch, an independent, university-based, anthropological and ethnographic field-research and medical human rights project. Whereas living-related (altruistic) and living-unrelated (commercial) donation are often treated as very different phenomena, I will illustrate what social elements are shared. In both instances, paid kidney sellers and related donors, are often responding to family pressures and to a call to "sacrifice".

This paper examined whether the reported health impacts of frequent eating at a fast food or quick service restaurant on health were related to having such a restaurant near home. Logistic regressions estimated associations between frequent fast food or quick service restaurant use and health status, being overweight or obese, having a cardiovascular disease or diabetes, as binary health outcomes. In all, 2001 participants in the 2008-2009 Seattle Obesity Study survey were included in the analyses. Results showed eating ⩾2 times a week at a fast food or quick service restaurant was associated with perceived poor health status, overweight and obese. However, living close to such restaurants was not related to negative health outcomes. Frequent eating at a fast food or quick service restaurant was associated with perceived poor health status and higher body mass index, but living close to such facilities was not.

The purpose of this cross-sectional observational study was to identify ethnic differences in body composition and obesity-related risk factors between Chinese and white males living in China. 115 Chinese and 114 white male pilots aged 28–63 years were recruited. Fasting body weight, height and blood pressure were measured following standard procedures. Whole-body and segmental body composition were measured using an 8-contact electrode bioimpedance analysis (BIA) system. Fasting serum glucose, fasting plasma total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, and triglycerides (TG) were assessed using automatic biochemistry analyzer. After adjusting for age and body mass index (BMI), Chinese males had significantly higher percentage of body fat (PBF) both with respect to whole body (Chinese: 23.7%±0.2% vs. Whites: 22.4%±0.2%) and the trunk area (Chinese: 25.0%±0.3% vs. Whites: 23.2%±0.3%) compared to their white counterparts. At all BMIs, Chinese males had significantly higher fasting glucose levels (Chinese: 5.7±1.0 mmol/L vs. Whites: 5.2±1.0 mmol/L) but lower high-density lipoprotein levels (Chinese: 0.8±1.0 mmol/L vs. Whites: 1.0±1.0 mmol/L) than white males. In addition, a marginally significantly higher diastolic blood pressure was found among Chinese men than that among white men (Chinese: 80±1.0 mmHg vs. Whites: 77±1.0 mmHg). Chinese males had more body fat and a greater degree of central fat deposition pattern than that seen in white males in the present study. Furthermore, data on blood pressure, fasting glucose and blood lipids suggest that Chinese men may be more prone to obesity-related risk factors than white men. PMID:21625549

The contribution of applied social sciences to obesity stigma-related public health approaches.

PubMed

Bombak, Andrea E

2014-01-01

Obesity is viewed as a major public health concern, and obesity stigma is pervasive. Such marginalization renders obese persons a "special population." Weight bias arises in part due to popular sources' attribution of obesity causation to individual lifestyle factors. This may not accurately reflect the experiences of obese individuals or their perspectives on health and quality of life. A powerful role may exist for applied social scientists, such as anthropologists or sociologists, in exploring the lived and embodied experiences of this largely discredited population. This novel research may aid in public health intervention planning. Through these studies, applied social scientists could help develop a nonstigmatizing, salutogenic approach to public health that accurately reflects the health priorities of all individuals. Such an approach would call upon applied social science's strengths in investigating the mundane, problematizing the "taken for granted" and developing emic (insiders') understandings of marginalized populations.

To compare physical activity (PA) measured by 4 methods in adults under free-living conditions in relation to selected demographic and anthropometric variables. Cohort study. Department of Sports Medicine. Clinically healthy men (81) and women (69) aged 45 to 64 years. Physical activity monitoring for 7 consecutive days under free-living conditions by pedometer (P) and accelerometer (A) simultaneously and PA questionnaires: International Physical Activity Questionnaire (IPAQ) and Seven-Day Physical Activity Questionnaire Recall (SDPAR) completed after the 7-day PA. Comparison of PA measured by pedometer, IPAQ, and SDPAR with accelerometer with regard to age, body mass, gender, and obesity type. Total energy expenditure (EE) by IPAQ was higher than A (P < 0.001) in both groups regardless of age, body mass, or obesity type. Mean EE value by P was greater than A (P < 0.001) in central-obesity males and lower than A (P < 0.001) in central-obesity females. There were differences in step counts in women, unnoticed in men. SDPAR overestimated total EE in gynoid-obesity males and in central-obesity females compared with A. Ninety-five percent CI was the largest around IPAQ compared with P and SDPAR, with SDPAR showing the best agreement with A. Body mass and obesity type influenced PA measurements. To monitor PA, it is recommended to use pedometer in normal bodyweight and overweight groups while accelerometer is advisable in obese subjects. A combined approach of objective and subjective PA monitoring tools is preferable.

Disadvantaged communities provide adverse psychosocial exposures that have been linked to high levels of stress, and this may provide one explanatory pathway linking socioeconomic disadvantage to obesity. This study used hair cortisol analysis to quantify associations between stress and body mass index (BMI), and between hair cortisol and perceived psychological stress levels, in women and children living in socioeconomically disadvantaged neighborhoods. Participants were a volunteer sample of 70 women from the Resilience for Eating and Activity Despite Inequality study, including 30 maternal-child pairs. Women self-reported body weight, height and perceived psychological stress using the Perceived Stress Scale (PSS), and provided hair samples for themselves and their child. Children's body weight and height were measured. Following extraction, hair cortisol levels were measured using enzyme-linked immunosorbent assay. Multiple linear regression models examined associations between stress and BMI, and between hair cortisol and perceived stress levels in women and children. Women's hair cortisol levels were not associated with their BMI or PSS scores. Women's PSS scores were positively associated with their BMI (p = 0.015). Within maternal-child pairs, mothers and children's hair cortisol levels were strongly positively associated (p = 0.006). Maternal hair cortisol levels and PSS scores were unrelated to their child's zBMI. Children's hair cortisol levels were not associated with their zBMI or with their mother's PSS score. Findings suggest that cortisol-based and perceived psychological measures of stress may be distinct among women and children living in disadvantaged neighborhoods. Perceived psychological measures may be more important predictors of weight-related risk.

Prevalence of overweight and obesity is rising. Hence, it is likely that a higher proportion of women undergoing assisted reproduction treatment are overweight or obese. In a retrospective cross-sectional analysis using routinely collected data of an IVF Unit and maternity hospital in a tertiary care setting in the UK, direct costs were assessed for all weight classes. Costs for underweight, overweight and obese were compared with those for women with normal body mass index (BMI). Of 1756 women, who underwent their first cycle of IVF between 1997 and 2006, 43 (2.4%) were underweight; 988 (56.3%) had normal BMI; 491 (28.0%) were overweight; 148 (8.4%) were obese (class I) and 86 (4.9%) were obese (class II). The mean (95% CI) cost of each live birth resulting from IVF was pound 18,747 (13 864-27 361) in underweight group; pound 16,497 (15 374-17 817) in women with normal BMI; pound 18,575 (16,648-21,081) in overweight women; pound 18,805 (15 397-23 554) in obese class I; pound 20,282 (15 288-28 424) in obese class II or over. The cost of a live birth resulting from IVF is not different in underweight, overweight and obese class I when compared with women with normal BMI. However, due to increased obstetric complications weight loss should still be recommended prior to commencing IVF even in overweight or obese (class I) women.

Aberrant mesolimbic dopamine-opiate interaction in obesity.

Dopamine and opioid neurotransmitter systems share many functions such as regulation of reward and pleasure. μ-Opioid receptors (MOR) modulate the mesolimbic dopamine system in ventral tegmental area and striatum, key areas implicated in reward. We hypothesized that dopamine and opioid receptor availabilities correlate in vivo and that this correlation is altered in obesity, a disease with altered reward processing. Twenty lean females (mean BMI 22) and 25 non-binge eating morbidly obese females (mean BMI 41) underwent two positron emission tomography scans with [(11)C]carfentanil and [(11)C]raclopride to measure the MOR and dopamine D2 receptor (DRD2) availability, respectively. In lean subjects, the MOR and DRD2 availabilities were positively associated in the ventral striatum (r=0.62, p=0.003) and dorsal caudate nucleus (r=0.62, p=0.004). Moreover, DRD2 availability in the ventral striatum was associated with MOR availability in other regions of the reward circuitry, particularly in the ventral tegmental area. In morbidly obese subjects, this receptor interaction was significantly weaker in ventral striatum but unaltered in the caudate nucleus. Finally, the association between DRD2 availability in the ventral striatum and MOR availability in the ventral tegmental area was abolished in the morbidly obese. The study demonstrates a link between DRD2 and MOR availabilities in living human brain. This interaction is selectively disrupted in mesolimbic dopamine system in morbid obesity. We propose that interaction between the dopamine and opioid systems is a prerequisite for normal reward processing and that disrupted cross-talk may underlie altered reward processing in obesity.

Parents play a critical role in their children's lifestyle habits. The objective was to assess the effect of parenting style on the risk of childhood obesity, and to determine whether poverty was a moderator of the association. Participants were from the 1994-2008 cross-sectional samples of the National Longitudinal Survey of Children and Youth (NLSCY), a nationally representative survey of Canadian youth. Factor and cluster analyses identified four parenting styles consistent with Baumrind's parenting style prototypes. Multivariable logistic regression assessed the risk of obesity based on parenting style after adjusting for covariates. Analyses were stratified by age (preschool: 2-5years of age, n=19,026; school-age: 6-11years of age, n=18,551) and the moderating effect of poverty (household incomeobese, respectively. In preschool children, poverty moderated this association: authoritarian and negligent parenting was associated with 44% (CI: 1.3-1.7) and 26% (CI: 1.1-1.4) increased likelihood of obesity, respectively, but only among the children not living in poverty. In school-age children, poverty was not a moderator. Parenting style is associated with childhood obesity, but may be moderated by poverty. Successful strategies to combat childhood obesity should reflect the independent and interactive associations of sociodemographic and social-familial influences on health especially in early childhood.

Interest in the assignment and frequency analysis of haplotypes in samples of unrelated individuals has increased immeasurably as a result of the emphasis placed on haplotype analyses by, for example, the International HapMap Project and related initiatives. Although there are many available computer programs for haplotype analysis applicable to samples of unrelated individuals, many of these programs have limitations and/or very specific uses. In this paper, the key features of available haplotype analysis software for use with unrelated individuals, as well as pooled DNA samples from unrelated individuals, are summarised. Programs for haplotype analysis were identified through keyword searches on PUBMED and various internet search engines, a review of citations from retrieved papers and personal communications, up to June 2004. Priority was given to functioning computer programs, rather than theoretical models and methods. The available software was considered in light of a number of factors: the algorithm(s) used, algorithm accuracy, assumptions, the accommodation of genotyping error, implementation of hypothesis testing, handling of missing data, software characteristics and web-based implementations. Review papers comparing specific methods and programs are also summarised. Forty-six haplotyping programs were identified and reviewed. The programs were divided into two groups: those designed for individual genotype data (a total of 43 programs) and those designed for use with pooled DNA samples (a total of three programs). The accuracy of programs using various criteria are assessed and the programs are categorised and discussed in light of: algorithm and method, accuracy, assumptions, genotyping error, hypothesis testing, missing data, software characteristics and web implementation. Many available programs have limitations (eg some cannot accommodate missing data) and/or are designed with specific tasks in mind (eg estimating haplotype frequencies rather than

Relative body weight is typically inversely associated with social status in affluent societies but studies comparing the social patterning of relative body weight and obesity in different countries have only seldom been conducted. The aim of this study was to analyse and compare the social patterning of relative weight and obesity by occupational status, educational attainment and marital status between Danish and Finnish women and men. Data from the Finnish Survey on Living Conditions and the Danish Health and Morbidity Survey, both collected in 1994, were compared. Relative weight was studied by using body mass index (BMI), and those with BMI > or =30 kg/m(2) were regarded as obese. Logistic regression analysis was used to examine the social patterning of obesity in the pooled dataset. Two-variable interaction effects were tested separately. Compared with their Danish counterparts, Finnish women and men had higher average relative weight and they were more often obese. There were no country differences in the socio-economic patterning of obesity by educational attainment, but a stronger patterning of obesity by occupational status was found among Danish women. Moreover, non-married women in Denmark were more likely to be obese than their married counterparts. Finns have higher relative weight and they are more often obese than Danes. The social patterning of obesity was similar in both studied countries but stronger in Denmark.

Nowadays, it is an evidence that maternal obesity is an important predictor of obesity in the descendants, not being consensual if that influence comes from the interaction between genes and facilitators family contexts or both. 1) To determinate the prevalence of the child overweight; 2) to classify the nutritional status and metabolic risk of the progenitors; 3) to analyze the effect of the markers of the family metabolic risk in the expression of the illness in the child. Descriptive study composed by 1424 children, average age 4.58 years old and their mothers, average age 34.47 years old, living in several parts of Portugal. The children's anthropometric measures were evaluated and classified according to the NCHS referential (CDC, 2000)(1) and of the progenitors by the orientations of the WHO (2000)(2) and Portugal, DGS (2005).(3) Social demographic data was obtained by filling in the Food Frequency Questionnaire adapted from Rito (2007).(4) The overweight affected 34.3% of the children, (including 17.4% obesity), being the higher values on boys (36.8%) and in 5 year old children (39.5). In 41.9% of the progenitors overweight was noted (12.1% obesity), being higher in mothers with low scholarship, low income, older and living in a rural area. The probability of the child to be overweighted was 1.4 times higher when mothers were overweight, and close to 2 times in the relationship mother/daughter. Others enabling factors were revealed, like weight gain above recommended during pregnancy and a higher weight at birth. Due to the obtained interferences, it is accepted the existence of enabling factors of maternal and child markers in the development of overweight in the child, so that the prevention of child obesity should consider not only the environmental dimension but also the genetic heritage.

Patients with blood, immune, or metabolic diseases may require a stem cell transplant as part of their treatment. However, 70% of patients do not have a suitable human leukocyte antigen match in their family, and need an unrelated donor. Individuals can register as potential donors at stem cell drives, where they provide consent and a tissue sample for human leukocyte antigen typing. The ideal donors are young, male, and from a diversity of ethnic backgrounds. However, in Canada, non-Caucasian males ages 17 to 35 years represent only 8.8% of listed donors. The Stem Cell Club is a non-profit organization founded in 2011 in Canada that aims to augment recruitment of the most needed donors. The initiative published a recruitment toolkit online (www.stemcellclub.ca). Currently, there are 12 chapters at universities across Canada. To date, the Stem Cell Club has recruited 6585 potential registrants, representing 1.63% of donors on Canada's donor-database. Of the recruited registrants, 58.3% were male; 60.3% of males self-reported as non-Caucasian, and 78.5% were ages 17 to 25 years. From 2015 to 2016, the initiative recruited 13.7% of all ethnically diverse males ages 17 to 35 years listed in Canada's donor database. Data from this initiative demonstrate sustainability and performance on key indicators of stem cell drive quality. The Stem Cell Club has developed a capacity to recruit 2600 donors annually, with the majority being males with a high degree of ethnic diversity. The initiative enhances the quality of Canada's unrelated donor-database, improving the chances that patients in need of an unrelated donor will find a match for transplant. The Stem Cell Club is a model relevant to recruitment organizations around the world. © 2017 AABB.

Nielson, Kristy A; Yee, Douglas; Erickson, Kirk I

2005-07-01

It has been well established that moderate physiological or emotional arousal modulates memory. However, there is some controversy about whether the source of arousal must be semantically related to the information to be remembered. To test this idea, 35 healthy young adult participants learned a list of common nouns and afterward viewed a semantically unrelated, neutral or emotionally arousing videotape. The tape was shown after learning to prevent arousal effects on encoding or attention, instead influencing memory consolidation. Heart rate increase was significantly greater in the arousal group, and negative affect was significantly less reported in the non-arousal group after the video. The arousal group remembered significantly more words than the non-arousal group at both 30 min and 24 h delays, despite comparable group memory performance prior to the arousal manipulation. These results demonstrate that emotional arousal, even from an unrelated source, is capable of modulating memory consolidation. Potential reasons for contradictory findings in some previous studies, such as the timing of "delayed" memory tests, are discussed.

Background: This paper examined whether the reported health impacts of frequent eating at a fast food or quick service restaurant on health were related to having such a restaurant near home. Methods: Logistic regressions estimated associations between frequent fast food or quick service restaurant use and health status, being overweight or obese, having a cardiovascular disease or diabetes, as binary health outcomes. In all, 2001 participants in the 2008–2009 Seattle Obesity Study survey were included in the analyses. Results: Results showed eating ⩾2 times a week at a fast food or quick service restaurant was associated with perceived poor health status, overweight and obese. However, living close to such restaurants was not related to negative health outcomes. Conclusions: Frequent eating at a fast food or quick service restaurant was associated with perceived poor health status and higher body mass index, but living close to such facilities was not.

As of 2013, 65% of the world's population lived in countries where overweight/obesity kills more people than being underweight. Evolutionary perspectives provide a holistic understanding of both how and why obesity develops and its long-term implications. To test whether the maternal capital hypothesis, an evolutionary perspective, is viable for explaining the development of obesity in adulthood. Restricted-use data from the National Longitudinal Study of Adolescent Health (Add Health; n = 11 403) was analysed using logistic regressions. The sample included adolescents and their biological mothers. The odds of obesity in adulthood increased by 22% for every standard deviation increase in lack of maternal capital (Exp (B) = 1.22, p < .001). That is, individuals whose mothers were young, of an ethnic minority and had short breastfeeding durations were more likely to be obese in adulthood, even after controlling for other factors in infancy, adolescence and adulthood. The results showed that those whose mothers had lower capital were more prone to later life disease (specifically, obesity). The maternal capital perspective is useful for explaining how and why early life characteristics (including maternal resources) predict obesity in adulthood. Implications of the findings are discussed.

In China, the prevalence of overweight and obesity appears to be increasing at unacceptable levels among young people living in major cities undergoing rapid economic growth. To report the prevalence of overweight and obesity among Shanghai inner city youth using the recently published International Obesity Task Force (IOTF) Asian definition. Secondary analysis of children aged 8-15 years who participated in the Shanghai Schools' Physical Fitness Examinations, a representative school-based survey. Height and weight were measured and body mass index (kg/m(2)) was calculated. The prevalence of overweight and obesity was determined using the IOTF children's BMI cut-points for Asian populations, equivalent to an adult BMI of 23 g/m(2) (overweight) and 27 kg/m(2) (obese). The prevalence of combined overweight and obesity was 49.1% for boys and 30.8% for girls aged 8-15-years. Almost one-in-five boys were obese, compared with 8.4% of girls. In boys the prevalence of overweight appeared to increase from age 10 years. The high prevalence of combined overweight and obesity among urban Chinese youth, especially among boys, requires immediate health promotion intervention.

We propose a method to analyze family-based samples together with unrelated cases and controls. The method builds on the idea of matched case–control analysis using conditional logistic regression (CLR). For each trio within the family, a case (the proband) and matched pseudo-controls are constructed, based upon the transmitted and untransmitted alleles. Unrelated controls, matched by genetic ancestry, supplement the sample of pseudo-controls; likewise unrelated cases are also paired with genetically matched controls. Within each matched stratum, the case genotype is contrasted with control pseudo-control genotypes via CLR, using a method we call matched-CLR (mCLR). Eigenanalysis of numerous SNP genotypes provides a tool for mapping genetic ancestry. The result of such an analysis can be thought of as a multidimensional map, or eigenmap, in which the relative genetic similarities and differences amongst individuals is encoded in the map. Once constructed, new individuals can be projected onto the ancestry map based on their genotypes. Successful differentiation of individuals of distinct ancestry depends on having a diverse, yet representative sample from which to construct the ancestry map. Once samples are well-matched, mCLR yields comparable power to competing methods while ensuring excellent control over Type I error. PMID:20862653

The Behavior Screening Questionnaire (BSQ) was used to determine whether 2 1/2-3 1/2 yr old children living near the TMI nuclear reactor were more disturbed than children living near another nuclear plant or near a fossil-fuel facility in Pennsylvania when assessed 2 1/2 yr later. The prevalence of behavior problems was 11%. Differences among the sites in overall rates and individual symptoms were small. Perceptions of environmental stress among the TMI sample of mothers were unrelated to BSQ scores, whereas in the comparison sites, where unemployment was rising, economic concerns were meaningfully related to the BSQ.

Background Various aspects of the environment are correlated with obesity. Most of the previous work in this area centers on the built environment. We sought to better understand the association of the natural environment with obesity. Methods We used the Natural Amenities Scale to characterize the attractiveness of 2,545 US counties based on access to open water, varied topography, and mild climate. We obtained the height, weight, age, sex, and address of adults from three different sources. The Departments of Motor Vehicles from seven US states provided over 38 million records. A web survey contributed 3,012 from 48 states and the District of Columbia. A clinical study of adults with diabetes from four states provided 974 more for a total of 38,159,046 analyzable records. We used logistic regression to model the association of obesity with natural amenities while controlling for age, sex, year of data collection, and various socioeconomic characteristics of the county. Results Natural amenities were inversely associated with obesity in all three populations. Over 20% of residents of low amenity areas were obese, but less than 10% of those living with the best natural amenities were obese. Conclusions The natural environment may affect health. Residing in areas with access to open water and a variety of topographic features as well as cool, dry summers and warm, sunny winters is associated with lower rates of obesity. PMID:26719821

Obesity is the nutritional disorder which has shown the greatest increase in prevalence, even in those countries in which deficiency diseases represent a severe public health problem. The goal of the present study was to analyse the anthropometric profile of a community living in the outskirts of Maceió, capital of Alagoas (northeastern Brazil), and to investigate the hypothesis of a coexistence of undernutrition and obesity in a very low-income population. The survey was conducted on 315 families (1247 individuals). Among the children (aged < or =10 years), the prevalence of wasting, stunting and wasting plus stunting was 3.8, 8.3 and 8.7 % respectively. Wasting (10.2 %) was the most prevalent form of undernutrition among adolescents; nonetheless, a higher frequency of stunting (11 %) and overweight-obesity (5.5 %) was seen specifically in girls, in agreement with trends found in other studies. Adults exhibited a high prevalence of overweight-obesity (25 %), but stunting was also present (22 %). Of the stunted individuals, 30 % were overweight-obese and 16.3 % were underweight. There were eighty-six families with at least one parent who was underweight (27 %) and 104 families with at least one parent who was overweight (33 %). Underweight and overweight-obesity were both present in ninety-six households (30 %). These results may indicate that better living conditions in urban areas in a population 'adapted' to chronic famine might increase the susceptibility to obesity. Considering the harm caused by the cumulative effect of these two conditions (undernutrition in childhood and obesity in adult life) there is a clear need for new studies to uncover the determinant factors so that preventive measures can be implemented.

Public policy to prevent childhood obesity, and the role of pediatric endocrinologists.

PubMed

Friedman, Roberta R; Schwartz, Marlene B

2008-08-01

Childhood overweight and obesity prevalence rates in the United States are steadily increasing. Public health experts consider a host of overarching and powerful influences beyond any one person's control to be the pivotal causes of childhood obesity. Consequently, it is more useful from a prevention and policy standpoint to examine the increasingly 'toxic environments' in which we live, consider a comprehensive strategy, and introduce, implement, and enforce public health policy to change those environments. In this paper we give an overview of different types of public policies that have been proposed as pieces of the complex solution to the growing problem of childhood obesity. We review some of the strategies needed, and the barriers to overcome, in order to pass effective policy, and discuss the important role pediatric endocrinologists can play in the fight to win effective policy campaigns to reverse the epidemic of childhood obesity.

The key to unlocking the virtual body: virtual reality in the treatment of obesity and eating disorders.

Riva, Giuseppe

2011-03-01

Obesity and eating disorders are usually considered unrelated problems with different causes. However, various studies identify unhealthful weight-control behaviors (fasting, vomiting, or laxative abuse), induced by a negative experience of the body, as the common antecedents of both obesity and eating disorders. But how might negative body image--common to most adolescents, not only to medical patients--be behind the development of obesity and eating disorders? In this paper, I review the "allocentric lock theory" of negative body image as the possible antecedent of both obesity and eating disorders. Evidence from psychology and neuroscience indicates that our bodily experience involves the integration of different sensory inputs within two different reference frames: egocentric (first-person experience) and allocentric (third-person experience). Even though functional relations between these two frames are usually limited, they influence each other during the interaction between long- and short-term memory processes in spatial cognition. If this process is impaired either through exogenous (e.g., stress) or endogenous causes, the egocentric sensory inputs are unable to update the contents of the stored allocentric representation of the body. In other words, these patients are locked in an allocentric (observer view) negative image of their body, which their sensory inputs are no longer able to update even after a demanding diet and a significant weight loss. This article discusses the possible role of virtual reality in addressing this problem within an integrated treatment approach based on the allocentric lock theory. © 2011 Diabetes Technology Society.

Obesity in infertile women increases the costs of fertility treatments, reduces their effectiveness and increases significantly the risks of many complications of pregnancy and for the newborn. Studies suggest that even a modest loss of 5-10 % of body weight can restore ovulation. However, there are gaps in knowledge regarding the benefits and cost-effectiveness of a lifestyle modification program targeting obese infertile women and integrated into the fertility clinics. This study will evaluate clinical outcomes and costs of a transferable interdisciplinary lifestyle intervention, before and during pregnancy, in obese infertile women. We hypothesize that the intervention will: 1) improve fertility, efficacy of fertility treatments, and health of mothers and their children; and 2) reduce the cost per live birth, including costs of fertility treatments and pregnancy outcomes. Obese infertile women (age: 18-40 years; BMI ≥30 kg/m(2) or ≥27 kg/m(2) with polycystic ovary syndrome) will be randomised to either a lifestyle intervention followed by standard fertility treatments after 6 months if no conception has been achieved (intervention group) or standard fertility treatments only (control group). The intervention and/or follow-up will last for a maximum of 18 months or up to the end of pregnancy. Evaluation visits will be planned every 6 months where different outcome measures will be assessed. The primary outcome will be live-birth rates at 18 months. The secondary outcomes will be sub-divided into four categories: lifestyle and anthropometric, fertility, pregnancy complications, and neonatal outcomes. Outcomes and costs will be also compared to similar women seen in three fertility clinics across Canada. Qualitative data will also be collected from both professionals and obese infertile women. This study will generate new knowledge about the implementation, impacts and costs of a lifestyle management program in obese infertile women. This information

Social jetlag, obesity and metabolic disorder: investigation in a cohort study.

Obesity is one of the leading causes of preventable death worldwide. Circadian rhythms are known to control both sleep timing and energy homeostasis, and disruptions in circadian rhythms have been linked with metabolic dysfunction and obesity-associated disease. In previous research, social jetlag, a measure of chronic circadian disruption caused by the discrepancy between our internal versus social clocks, was associated with elevated self-reported body mass index, possibly indicative of a more generalized association with obesity and metabolic dysfunction. We studied participants from the population-representative Dunedin Longitudinal Study (N=1037) to determine whether social jetlag was associated with clinically assessed measurements of metabolic phenotypes and disease indicators for obesity-related disease, specifically, indicators of inflammation and diabetes. Our analysis was restricted to N=815 non-shift workers in our cohort. Among these participants, we found that social jetlag was associated with numerous clinically assessed measures of metabolic dysfunction and obesity. We distinguished between obese individuals who were metabolically healthy versus unhealthy, and found higher social jetlag levels in metabolically unhealthy obese individuals. Among metabolically unhealthy obese individuals, social jetlag was additionally associated with elevated glycated hemoglobin and an indicator of inflammation. The findings are consistent with the possibility that 'living against our internal clock' may contribute to metabolic dysfunction and its consequences. Further research aimed at understanding that the physiology and social features of social jetlag may inform obesity prevention and have ramifications for policies and practices that contribute to increased social jetlag, such as work schedules and daylight savings time.

Introduction This randomized pilot trial evaluated two training modalities for first-line, evidence-based pediatric obesity services (screening and goal-setting) among nursing students. Method Participants (N=63) were randomized to Live Interactive Training (Live) or Web-facilitated Self-study Training (Web). Pre-training, post-training, and one-month follow-up assessments evaluated training feasibility, acceptability, and impact (knowledge, and skill via simulation). Moderator (previous experience) and predictor (content engagement) analyses were conducted. Results Nearly-all (98%) participants completed assessments. Both trainings were acceptable, with higher ratings for Live and participants with previous experience (p’s<.05). Knowledge and skill improved from pre-training to post-training and follow-up in both conditions (p’s<.001). Live demonstrated greater content engagement (p’s<.01). Conclusions The training package was feasible, acceptable, and efficacious among nursing students. Given that Live had higher acceptability and engagement, and online training offers greater scalability, integrating interactive Live components within Web-based training may optimize outcomes, which may enhance practitioners’ delivery of pediatric obesity services.

Knowledge of cross-reactivity between foods is useful so that potentially cross-reactive allergens can be avoided in diet trials. To evaluate allergenic cross-reactivity in related foods. Sera from 469 dogs with suspected adverse food reactions. An IgE-based serological assay using 19 food allergens was performed in 469 dogs. Pairwise comparisons were used to calculate the odds ratios (ORs) for each food pair, with significance at P < 0.0002 by Holm-Bonferroni correction, both in all 469 dogs and in the 261 of 469 dogs with at least one positive reaction. One-way ANOVA with Tukey's post hoc tests (significance at P < 0.05) were used to test for differences between mean logE ORs in different food groups. Inhibition enzyme-linked immunosorbent assays (ELISAs) were performed to assess allergenic cross-reactivity between beef, lamb and cow's milk. Significant associations were observed between both related and unrelated food pairs. Associations were, however, more frequent and stronger among related than unrelated foods. In all 469 dogs, 38 of 43 related food pairs were significantly associated [mean (SD) logE OR 3.4 (0.9)] compared with 79 of 128 unrelated pairs [2.7 (1.0)], P < 0.0002. In positive dogs, 32 of 43 related pairs were significantly associated [2.7 [1.0)] compared with 49 of 128 unrelated pairs [1.8 (1.0)], P < 0.0002. Inhibition ELISAs confirmed the presence of cross-reactive IgE-binding epitopes in beef, lamb and cow's milk. The results suggest that related and potentially cross-reactive foods should be avoided in elimination diets. © 2016 ESVD and ACVD.

Socioeconomic inequality and obesity prevalence trends in Luxembourg, 1995-2007.

Overweight and obesity are becoming increasingly critical problems in most developed countries. Approximately 20% of adults in most European countries are obese. This study examines the prevalence of overweight and obesity in Luxembourg and their association with different demographic, socioeconomic (SES), and behavioural factors. The data used in this study were taken from 2 surveys on household income and living conditions conducted in 1995 and 2007. The target population was household residents aged 16 years and older, and body mass index (BMI) data were self-reported. Average BMI, overweight, and obesity prevalence rates were calculated according to each demographic (gender, nationality, marital status), SES (educational level, profession, and place of residence), and behavioural (physical activity and diet) factors. A multivariate logistic regression analysis was conducted to measure the relationship between obesity and demographic, SES, and behavioural factors. All analyses were conducted according to gender, and data used were weighted. Between 1995 and 2007, the average BMI remained nearly constant among men and women in the entire study population. Obesity prevalence increased by 24.5% through the study period (14.3% in 1995 to 17.8% in 2007). Obesity prevalence increased by 18.5% for men (15.1% in 1995 to 17.9% in 2007) and by 30% for women (13.6% in 1995 to 17.7% in 2007). Between 1995 and 2007, obesity increased sharply by 48.2% (from 11% to 16.3%) in Portuguese men, 76.7% (from 13.3% to 23.5%) in Portuguese women, 79.7% (from 17.2% to 30.9%) in widowed men, and 84.3% (from 12.1% to 22.3%) in divorced women. Multivariate logistic regression analysis showed that the relationship between the educational level and obesity was not statistically significant for men, but was significant for women. The prevalence of overweight and obesity is high in Luxembourg and has changed slightly in recent years. SES inequalities in obesity exist and are most compelling

Poor lifestyle habits, such as unhealthy eating and physical inactivity, are major contributors to increased adult morbidity and mortality from chronic diseases. Over the past decade there has been an increase in sedentary lifestyle and obesity in children and adolescents, both in North America and worldwide. Physicians need to be aware of the scope of this problem, provide anticipatory guidance to families and promote healthy active living in their practices.

Currently 67 % of the US population is overweight or obese and obesity is associated with several chronic medical conditions. Geographic areas where individuals lack access to healthy foods have been termed ‘food deserts’. The study aim was to examine if area of residence within Metro Detroit was associated with dietary intake, food and shopping behaviours, and BMI. Cross-sectional study. Participants were recruited in the waiting area of four primary-care clinics. Individuals (n 1004) completed a questionnaire comprising four sections: demographics; personal health status including self-reported height and weight; a modified diet, transportation and shopping survey; and a subscale from the Diet and Health Knowledge Survey. Seventy-four per cent of participants were female and the mean age was 46·7 (sd 15·0) years. In univariate analyses, living in Detroit was associated with being African American, unemployment, less education, no regular exercise, worse health self-rating and obesity (P < 0·0005 for all). Participants living in Detroit had a 3·06 (95 % CI 1·91, 4·21) kg/m2 larger BMI compared with people living outside the city (P < 0·0005) in univariate analyses, but the effect was attenuated when adjusted for demographics, disease status, shopping and eating behaviours, dietary intakes and diet knowledge (β = −0·46 kg/m2, 95 % CI −2·23, 1·30 kg/m2, P = 0·60). Overweight and obesity are highly prevalent both inside (82·9 %) and outside (72·8 %) the city of Detroit, presenting a major public health problem. However, living in this food desert was not significantly associated with BMI after potential covariates were considered.

To investigate the effect of five dimensions of social relationships on obesity and potential sex differences in these associations. This study used longitudinal data from the Swedish Level of Living Surveys (LNU) in 1991 and 2000. The sample included 3,586 individuals. The dimensions of social relationships examined in this study include emotional support, frequency of visiting friends, marital status, marital status changes, and a Social Relationships Index (SRI). Obesity status was based on BMI (kg/m(2)) and calculated with self-reported measurements. The association between social relationships and the incidence of obesity after 9 years of follow-up was evaluated through Poisson regressions. After controlling for confounders, we found that the lack of emotional support (RR = 1.98; 95% CI, 1.1-4.6) influenced the incidence of obesity among men. In addition, men with the lowest levels of SRI (RR = 2.22; 95% CI, 1.1-4.4) had an increased risk of being obese. Among women, SRI was not significantly associated with obesity. Women who changed their marital status from married to unmarried had lower risk of obesity (RR = 0.39; 95% CI, 0.2-0.9). This study provides evidence for the effect of social relationships on the incidence of obesity, with significant differences by sex. Copyright © 2013 The Obesity Society.

Specific Suppressor of Cytokine Signaling (SOCS) members, such as SOCS7, may play a role in the development of insulin resistance (IR) owing to their ability to inhibit insulin signaling pathways. The objective was to explore the association between common variants and related haplotypes in SOCS7 gene and metabolic traits related to obesity, lipid metabolism and IR. 780 unrelated men were included in a cross-sectional study. We selected three tagged SNPs that capture 100% of SNPs with minor allele frequency ≥ 0.10. Analyses were done separately for each SNP and followed up by haplotype analysis. rs8074124C was associated with both obesity (p = 0.005) and abdominal obesity (p = 0.002) and allele C carriers showed, in comparison with TT carriers, lower BMI (p = 0.001) and waist circumference (p = 0.001). rs8074124CC- carriers showed lower fasting insulin (p = 0.017) and HOMA-IR (p = 0.018) than allele T carriers. rs12051836C was associated with hypertriglyceridemia (p = 0.009) and hypertriglyceridemic waist (p = 0.006). rs12051836CC- carriers showed lower fasting insulin (p = 0.043) and HOMA-IR (p = 0.042). Haplotype-based association analysis (rs8074124 and rs12051836 in that order) showed associations with lipid and obesity -related phenotypes, consistent with single locus analysis. Haplotype analysis also revealed association between haplotype CT and both decreased HDL-C (p = 0.026) and HDL-C (p = 0.014) as a continuous variable. We found, for the first time, significant associations between SOCS7 common variants and related haplotypes and obesity, IR and lipid metabolism disorders. Crown Copyright © 2011.

2015-01-01

Prevalence rates of cardiometabolic risk factors vary largely among overweight children. This study investigated the relationships between dietary habits and cardiometabolic health among obese children living in a city of Northern Italy. Dietary habits were collected in 448 obese subjects aged 6-18 years, attending an obesity outpatient center in Milan. Anthropometry, blood pressure (BP), lipids, fasting and post-load glucose, and insulin were measured. Physical activity was assessed in adolescents using a questionnaire. Frequency of glucose intolerance, hypertension and dyslipidemia was 0.7%, 13% and 27.2%, respectively. Plausible reporters consumed more animal protein and sodium and less legumes than recommended in nutritional recommendations and adequate amounts of fiber mainly derived from whole grains. Subjects skipping breakfast had unhealthy diets and greater body fatness. After adjustment for confounders, waist/height and fasting glucose were associated with sodium intake (r =0.149 and r = 0.142, respectively; p < 0.05), 2-hour glucose with fiber (r = -0.172; p < 0.01), and BP with vegetable protein intake (systolic r = -0.120 (p < 0.05); diastolic r = -0.267 (p < 0.01)). Hypertensive children consumed less vegetable protein than normotensive children. The cardiometabolic health of obese children improves with vegetable protein and whole grain intake, whereas dysglycemia and adiposity increase with sodium intake.

The role of obesity in the development of polycystic ovary syndrome.

Polycystic Ovary Syndrome (PCOS) is one of the common endocrine diseases that affects women in their reproductive age. PCOS has diverse clinical implications that include reproductive (infertility, hyperandrogenism, hirsutism), metabolic (insulin resistance, impaired glucose tolerance, type 2 diabetes mellitus, cardiovascular diseases) and psychological features (increased anxiety, depression and worsened quality of life). The exact patho-physiology of PCOS is complex and remains largely unclear. The prevalence of PCOS is estimated at 4-18%, depending on diverse factors discussed ahead. The phenotype varies widely depending on life stage, genotype, ethnicity and environmental factors including lifestyle and body weight. During the last decades, obesity and excess weight are major chronic diseases all around the word. Obesity increases some features of PCOS such as hyperandrogenism, hirsutism, infertility and pregnancy complications. Both obesity and insulin resistance increase diabetes mellitus type 2 and cardiovascular diseases. Moreover, obesity impairs insulin resistance and exacerbates reproductive and metabolic features of PCOS. It is well known that obesity is associated with anovulation, pregnancy loss and late pregnancy complications (pre-eclampsia, gestational diabetes). Obesity in PCOS is also linked to failure or delayed response to the various treatments including clomiphene citrate, gonadotropins and laparoscopic ovarian diathermy. It has been reported that, after losing as little as 5 % of initial body weight obese women with PCOS improved spontaneous ovulation rates and spontaneous pregnancy. Therefore, the weight loss prior to conception improves live birth rate in obese women with or without PCOS. The treatment of obesity may include lifestyle therapy (diet and exercise), pharmacological treatment and bariatric surgery. In summary, weight loss is considered the first-line therapy in obese women with PCOS. In the present review, the consequence and

Prior research has identified numerous factors contributing to increased rates of childhood obesity. However, few studies have focused explicitly on the experience of community stakeholders in low-income communities. This study sought to capture the perspectives of these on-the-ground experts regarding major factors contributing to childhood obesity as well as gaps in current prevention and control efforts. We conducted semi-structured interviews with 39 stakeholders from different community sectors (e.g., healthcare providers, childcare providers, teachers). Data were drawn from the Massachusetts Childhood Obesity Research Demonstration project, a multi-level, multi-sector intervention designed to reduce childhood obesity being implemented in two low-income communities in Massachusetts. Interviews were conducted at baseline, transcribed, coded using grounded theory approach, and analyzed in NVivo 10.0. The vast majority of stakeholders had recently participated in obesity prevention strategies, and nearly all of them identified gaps in prevention efforts either within their organizations or in the broader community. In addition to factors previously identified in the literature, several themes emerged including the need to change policies to increase physical activity during school, offer healthier snacks in schools and afterschool programs, and increase communication and collaboration within the community in prevention efforts. Community stakeholders can impact the success of interventions by bridging the gap between science and lived experience. The results of this study can guide future research by highlighting the importance of including stakeholders' frontline experiences with target populations, and using information on identified gaps to augment intervention planning efforts.

Some marine mammals are so rarely seen that their life history and social structure remain a mystery. Around New Zealand, Gray's beaked whales (Mesoplodon grayi) are almost never seen alive, yet they are a commonly stranded species. Gray's are unique among the beaked whales in that they frequently strand in groups, providing an opportunity to investigate their social organization. We examined group composition and genetic kinship in 113 Gray's beaked whales with samples collected over a 20-year period. Fifty-six individuals stranded in 19 groups (2 or more individuals), and 57 whales stranded individually. Mitochondrial control region haplotypes and microsatellite genotypes (16 loci) were obtained for 103 whales. We estimated pairwise relatedness between all pairs of individuals and average relatedness within, and between, groups. We identified 6 mother-calf pairs and 2 half-siblings, including 2 whales in different strandings 17 years and 1500 km apart. Surprisingly, none of the adults stranding together were related suggesting that groups are not formed through the retention of kin. These data suggest that both sexes may disperse from their mothers, and groups consisting of unrelated subadults are common. We also found no instances of paternity within the groups. Our results provide the first insights into dispersal, social organization, and the mating system in this rarely sighted species. Why whales strand is still unknown but, in Gray's beaked whales, the dead can tell us much about the living. © The American Genetic Association 2017. All rights reserved.

Living donation is increasingly necessary to address the shortage of organs for transplantation. Analyzing attitudes and influences toward living donation is essential. This study sought to analyze the attitude toward living donation in the population of Bolivians residing in Spain, and the variables that influence their attitude. We selected a sample of Bolivians living in Spain. Respondents were selected using a stratified sampling by age and sex. We used a validated questionnaire of psychosocial aspects (the questionnaire of Proyecto Colaborativo Internacional Donante about Living Kidney Donation [Donación de Vivo Renal in Spanish]), which is self-administered and anonymous. The Student t test, χ(2), and Fisher tests, as well as logistic regression analysis, were used to analyze the gathered data. Of all respondents (n = 206), 83% (n = 170) were in favor of living-related donation, and 32% (n = 66) were in favor of living-unrelated donation. The rest, 8.5% (n = 18) were not in favor of living donation and 8.5% (n = 18) were undecided. Acceptance of the living donation was associated with the religious beliefs of the respondent (P = .014), with no worry about the scars that may remain after the donation (P = .016), and with the risk evaluation of living donation (P = .029). On multivariate analysis, the most important variable was the risk associated with living donation (odds ratio, 6.329; 95% CI, 30.303-1.328; P = .021). Attitudes toward living donation among the Bolivian population residing in Spain is favorable, and represents a group that may be encouraged to become donors. Copyright © 2015 Elsevier Inc.

Obesity and chronic diseases disproportionately affect African-American women in the rural South (US) and may be influenced by adherence to a typical Southern-style diet. There is a need to examine dietary patterns of this population and to determine if consumption of nutritionally rich foods like nuts is associated with consumption of other nutritious foods. The objectives of this study were to identify (1) dietary patterns of overweight/obese African-American women in the rural South; (2) the role that nuts play in the diet; (3) and adherence to federal food group recommendations across dietary patterns. Secondary data analysis of two baseline 24-h dietary recalls was performed on 383 overweight/obese African-American women enrolled in a weight loss intervention in Alabama and Mississippi between 2011 and 2013. Cluster analysis identified dietary patterns. t tests and chi-square tests tested demographic and dietary differences across clusters. The proportion of women in each cluster who met federal recommendations for fruit, vegetable, nuts, added sugar, and sodium intake was calculated. Two dietary patterns were found. Nut intake frequency was higher in cluster 2 (P < .001), which was characterized by a higher intake frequency of fruits and vegetables, but high mean daily intake of added sugar (12.26 ± 7.67 tsp) and sodium (2800 ± 881 mg). Ninety-two percent of participants in this cluster consumed red/processed meats daily. Even among women in this population who consume a more plant-based dietary pattern containing nuts, there is still a need to decrease intake of added sugar, sodium, and red meat.

Objective To examine whether the cross-sectional association between food insecurity and overweight/obesity varied according to birthplace and length of residence in the US among California women. Design Using cross-sectional, population-based data from the California Women’s Health Survey (CWHS) 2009–2012, we examined whether the association between food insecurity and overweight or obesity varied by birthplace-US length of residence. Setting California, US Subjects Women (n=16,259) 18 years and older Results Among US-born women, very low food security (PR 1.21, 95% CI 1.11–1.31) and low food security (PR 1.19, 95% CI 1.10–1.28) were significantly associated with higher prevalence of overweight/obesity, after controlling for age, marital status, race/ethnicity, poverty, and education. Among immigrant women who lived in the US for 10 years or longer, very low food security was significantly associated with higher prevalence of overweight/obesity, after controlling for covariates (PR 1.16, 95% CI 1.07–1.27). Among immigrant women who had lived in the US for less than 10 years, low and very low food security were not significantly associated with obesity, after controlling for covariates. Conclusions Food insecurity may be an important pathway through which weight may increase with longer US residence among immigrant women. Public health programs and policies should focus on increasing food security for all women, including immigrant women, as one strategy to reduce the prevalence of overweight/obesity. PMID:27890021

2013-01-01

Using a large social media database, Yahoo Answers, we explored postings to an online forum in which posters asked whether their height and weight qualify themselves as “skinny,” “thin,” “fat,” or “obese” over time and across forum topics. We used these data to better understand whether a higher-than-average body mass index (BMI) in one’s county might, in some ways, be protective for one’s mental and physical health. For instance, we explored whether higher proportions of obese people in one’s county predicts lower levels of bullying or “am I fat?” questions from those with a normal BMI relative to his/her actual BMI. Most women asking whether they were themselves fat/obese were not actually fat/obese. Both men and women who were actually overweight/obese were significantly more likely in the future to ask for advice about bullying than thinner individuals. Moreover, as mean county-level BMI increased, bullying decreased and then increased again (in a U-shape curve). Regardless of where they lived, posters who asked “am I fat?” who had a BMI in the healthy range were more likely than other posters to subsequently post on health problems, but the proportions of such posters also declined greatly as county-level BMI increased. Our findings suggest that obese people residing in counties with higher levels of BMI may have better physical and mental health than obese people living in counties with lower levels of BMI by some measures, but these improvements are modest.

Although a substantial body of literature has provided evidence supporting the positive effects of natural environments on well-being, little has been known about the specific spatial patterns of urban nature in promoting health-related quality of life (HRQOL) among children. This study assessed the association that the urban natural environment measured by landscape spatial patterns may have with obesity and HRQOL among Hispanic children. Ninety-two 4th and 5th grade students were recruited from Houston, Texas, and the Pediatric Quality of Life Inventory (PedsQL) was used to capture the children’s HRQOL. The quality of urban natural environments was assessed by quantifying the landscape spatial patterns, using landscape indices generated by Geographic Information Systems and remote sensing. From the bivariate analyses, children’s body mass index showed a significantly negative association with their HRQOL. After controlling for socio-demographic factors, the results revealed that larger and more tree areas were positively correlated with children’s HRQOL. In addition, those children living in areas with tree patches further apart from each other showed higher HRQOL. This research adds to the current multi-disciplinary area of research on environment-health relationships by investigating the roles of urban greeneries and linking their spatial structures with children’s HRQOL.

An unfavorable psychosocial environment has been associated with an increased prevalence of obesity among children. However, the available evidence on the association of low socioeconomic status and parent-child relationships with childhood obesity is scarce. The aim of our study was to conduct a simultaneous evaluation of the risks associated with pathological mother-child relationships, education level, and overweight/obesity among 4-6 year-old children. This cross-sectional study included 1489 mother-child pairs living in Kaunas city, Lithuania. The Parenting Stress Index was measured using the Parent-Child Dysfunctional Interaction subscale. Children's overweight/obesity was defined as the body mass index ≥18kg/m 2 . Logistic regression models as well as crude and adjusted odds ratios (OR) and their 95% confidence intervals (CI) were used to indicate the strength of the associations between childhood overweight/obesity, maternal education level, and psychosocial stress. The percentage of children with overweight/obesity rose with an increasing Parenting Stress Index score. The percentage of children with overweight/obesity in the group of parents with better education and normal mother-child relations was 6.0%, while in the group of less educated parents and pathological mother-child relations, this percentage reached 13.9%. The stratified multivariable model showed that, with reference to the group of better educated parents and normal mother-child relations, lower education level and pathological mother-child relations were statistically significant risk factors for overweight/obesity in 4-6 year-old children, increasing the OR of overweight/obesity (aOR: 2.43; 95% CI: 1.31-4.51). Pathological mother-child relations and maternal smoking mediated the effect of low maternal education level on children's BMI z-scores. Pathological mother-child relations, lower parental education levels, and smoking may be predictors of children's overweight/obesity. Measures

Obesity and metabolic comorbidities represent increasing health problems. Endocrine disrupting compounds (EDCs) are exogenous agents that change endocrine function and cause adverse health effects. Most EDCs are synthetic chemicals; some are natural food components as phytoestrogens. People are exposed to complex mixtures of chemicals throughout their lives. EDCs impact hormone-dependent metabolic systems and brain function. Laboratory and human studies provide compelling evidence that human chemical contamination can play a role in obesity epidemic. Chemical exposures may increase the risk of obesity by altering the differentiation of adipocytes. EDCs can alter methylation patterns and normal epigenetic programming in cells. Oxidative stress may be induced by many of these chemicals, and accumulating evidence indicates that it plays important roles in the etiology of chronic diseases. The individual sensitivity to chemicals is variable, depending on environment and ability to metabolize hazardous chemicals. A number of genes, especially those representing antioxidant and detoxification pathways, have potential application as biomarkers of risk assessment. The potential health effects of combined exposures make the risk assessment process more complex compared to the assessment of single chemicals. Techniques and methods need to be further developed to fill data gaps and increase the knowledge on harmful exposure combinations. PMID:23577225

Obesity is a risk factor in the development of several respiratory diseases. Lung volumes tend to be decreased, especially expiratory reserve volume, increasing expiratory flow limitation during tidal breathing. Barometric whole-body plethysmography is a non-invasive pulmonary function test that allows a dynamic study of breathing patterns. The objective of this study was to compare pulmonary function variables between obese and non-obese cats through the use of barometric whole-body plethysmography. Nine normal-weight and six obese cats were placed in the plethysmograph chamber, and different respiratory variables were measured. There was a significant decrease in tidal volume per kilogram (P = 0.003), minute volume per kilogram (P = 0.001) and peak inspiratory and expiratory flows per kilogram (P = 0.001) in obese cats compared with non-obese cats. Obesity failed to demonstrate a significant increase in bronchoconstriction index variable enhanced pause (Penh), as previously reported in humans and dogs. The results show that feline obesity impairs pulmonary function in cats, although a significant increase in bronchoconstriction indexes was not observed. Non-invasive barometric whole-body plethysmography can help characterise mechanical dysfunction of the airways in obese cats. © ISFM and AAFP 2014.

Childhood obesity continues to be a prominent health concern in the United States. Certain demographics of youth have a higher prevalence of obesity, including those living in rural settings, and African American females. Multiple determinants contribute to the childhood obesity epidemic, yet few studies have partnered with youth to investigate community-level determinants and solutions. This study involved youth to assess contextual determinants of childhood obesity in a community, create an action plan for the community, and report findings and actions pursued in partnership with a community-based organization (CBO) and a university. Seven African American female high school students were recruited to investigate factors that contribute to childhood obesity using photovoice, a methodology used in community-based participatory research (CBPR). Through photography and guided discussion, youth partners found a lack of access to healthy food and lack of safe recreation as primary contributors to obesity within their community. Social support from friends was believed to help prevent obesity. In response to findings, two projects were envisioned and implemented in the community, a walkability assessment and an intergenerational community garden. Throughout this study, youth proved to be reliable partners in research, provided unique perspectives while examining local factors perceived to contribute to childhood obesity, and offered thoughtful solutions.

Stepping towards causation: do built environments or neighborhood and travel preferences explain physical activity, driving, and obesity?

Evidence documents associations between neighborhood design and active and sedentary forms of travel. Most studies compare travel patterns for people located in different types of neighborhoods at one point in time adjusting for demographics. Most fail to account for either underlying neighborhood selection factors (reasons for choosing a neighborhood) or preferences (neighborhoods that are preferred) that impact neighborhood selection and behavior. Known as self-selection, this issue makes it difficult to evaluate causation among built form, behavior, and associated outcomes and to know how much more walking and less driving could occur through creating environments conducive to active transport. The current study controls for neighborhood selection and preference and isolates the effect of the built environment on walking, car use, and obesity. Separate analyses were conducted among 2056 persons in the Atlanta, USA based Strategies for Metropolitan Atlanta's Regional Transportation and Air Quality (SMARTRAQ) travel survey on selection factors and 1466 persons in the SMARTRAQ community preference sub-survey. A significant proportion of the population are "mismatched" and do not live in their preferred neighborhood type. Factors influencing neighborhood selection and individual preferences, and current neighborhood walkability explained vehicle travel distance after controlling for demographic variables. Individuals who preferred and lived in a walkable neighborhood walked most (33.9% walked) and drove 25.8 miles per day on average. Individuals that preferred and lived in car dependent neighborhoods drove the most (43 miles per day) and walked the least (3.3%). Individuals that do not prefer a walkable environment walked little and show no change in obesity prevalence regardless of where they live. About half as many participants were obese (11.7%) who prefer and live in walkable environments than participants who prefer car dependent environments (21.6%). Findings

Childhood obesity among the poor in Peru: Are there implications for cognitive outcomes?

PubMed

Wisniewski, Suzanne L

2017-08-01

This paper exploits three rounds of panel data provided by the Peruvian dataset of the Young Lives study to investigate the relationship between child cognition and obesity status among the poor. Child weight status is measured by a full distribution of child weight, from severely thin to obese, using data from a z-score for body mass index and cognition is measured by the Spanish version of the Picture Peabody Vocabulary Test (PPVT). This relationship is studied at age five and age eight (school age), and disaggregated across socioeconomic factors of gender, urban/rural setting and indigenous/nonindigenous status. The initial results suggests that obese children have higher cognitive scores and that this result is driven by those who are female, non-indigenous and live in an urban region. However, after correcting for possible bias due to unobservable heterogeneity, there is little evidence of this relationship. The one exception is for a weakly significant relationship between obese female children and higher cognition, a relationship which tends to weaken between the ages of five and eight. On the other end of the weight distribution, indigenous children who are severely thin or thin have significantly lower cognitive scores, a relationship that holds after correcting for possible bias and appears to strengthen between ages of five and eight. This paper contributes to a very small set of literature on child cognition and obesity, points to the importance of controlling for unobserved heterogeneity in estimation, and is the first of its kind to study this relationship in a developing country.

Genetic evolution of bacteriophage. I. Hybrids between unrelated bacteriophages P22 and Fels 2.

PubMed

Yamamoto, N

1969-01-01

A new bacteriophage species, designated F22, was isolated from phage P22 stocks grown on Salmonella typhimurium Q1 lysogenic for Fels 2 at a frequency of less than 10(-11). P22 has a very short tail with a hexagonal base plate and six spikes. Phage Fels 2 is morphologically similar to E. coli T-even phages, having a long tail with a contractile sheath and carrying no genetic region related to P22. Phage F22 is morphologically and serologically indistinguishable from Fels 2, but carries the c(c(1), c(2), and c(3)) markers of P22. The color markers h(21), g, and m(3) of P22 do not appear in F22. Thus, F22 is evidently a recombinant between the unrelated bacteriophages P22 and Fels 2. The recombination between unrelated bacteriophages could play an important role in the evolution of bacteriophages.

Obesity is a chronic disease of increasing prevalence reaching epidemic proportions. Genetic defects as well as epigenetic effects contribute to the obesity phenotype. Investigating gene (e.g. MC4R defects)-environment (behavior, infectious agents, stress) interactions is a relative new field of great research interest. In this study, we have made an effort to create an interactome (henceforth referred to as "obesidome"), where extrinsic stressors response, intrinsic predisposition, immunity response to inflammation and autonomous nervous system implications are integrated. These pathways are presented in one interactome network for the first time. In our study, obesity-related genes/gene products were found to form a complex interactions network.

Predictors of breastfeeding in overweight and obese women: data from Active Mothers Postpartum (AMP).

Excess maternal weight has been negatively associated with breastfeeding. We examined correlates of breastfeeding initiation and intensity in a racially diverse sample of overweight and obese women. This paper presents a secondary analysis of data from 450 women enrolled in a postpartum weight loss intervention (Active Mothers Postpartum [AMP]). Sociodemographic measures and body mass index (BMI), collected at 6 weeks postpartum, were examined for associations with breastfeeding initiation and lactation score (a measure combining duration and exclusivity of breastfeeding until 12 months postpartum). Data were collected September 2004-April 2007. In multivariable analyses, BMI was negatively associated with both initiation of breastfeeding (OR: .96; CI: .92-.99) and lactation score (β -0.22; P = 0.01). Education and infant gestational age were additional correlates of initiation, while race, working full-time, smoking, parity, and gestational age were additional correlates of lactation score. Some racial differences in these correlates were noted, but were not statistically significant. Belief that breastfeeding could aid postpartum weight loss was initially high, but unrelated to breastfeeding initiation or intensity. Maintenance of this belief over time, however, was associated with lower lactation scores. BMI was negatively correlated with breastfeeding initiation and intensity. Among overweight and obese women, unrealistic expectations regarding the effect of breastfeeding on weight loss may negatively impact breastfeeding duration. In general, overweight and obese women may need additional encouragement to initiate breastfeeding and to continue breastfeeding during the infant's first year.

To describe current prevalence of obesity and related non-communicable diseases (NCDs) in expatriates living in the United Arab Emirates (UAE). We used data from the cross-sectional UAE National Diabetes and Lifestyle Study (UAEDIAB), which surveyed adult expatriates living in the UAE for at least 4 years. We report crude prevalence of overweight and obesity, indicated by gender and ethnicity-specific body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) cut-offs, by lifestyle and biomedical characteristics, as well as age and sex-adjusted odds ratios. Out of a total of 3064 recruited expatriates (response rate 68%), 2724 had completed all stages of the UAEDIAB study. Expatriates were; 81% men, mean age 38 years (range 18-80), 71% South East Asians, and 36% university graduates. In this sample, the prevalence of overweight and obesity, by BMI, were 43.0 and 32.3%, respectively. 52.4 and 56.5% of participants were at a substantially increased risk according to WC and WHR, respectively. The prevalence of diabetes, hypertension and hypercholesterolemia were 15.5, 31.8, and 51.7%, respectively, with the prevalence of each being higher in those with obesity. Prevalence of obesity and associated NCDs are extremely high in UAE expatriates. Without comprehensive prevention and management, levels of disease will continue to increase and productivity will fall.

Food choice, eating behavior, and food liking differs between lean/normal and overweight/obese, low-income women.

PubMed

Dressler, Heidi; Smith, Chery

2013-06-01

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. Copyright © 2013 Elsevier Ltd. All rights reserved.

Therapeutic profile of single-fraction radiosurgery of vestibular schwannoma: unrelated malignancy predicts tumor control

Radiosurgery has become an accepted treatment option for vestibular schwannomas. Nevertheless, predictors of tumor control and treatment toxicity in current radiosurgery of vestibular schwannomas are not well understood. To generate new information on predictors of tumor control and cranial nerve toxicity of single-fraction radiosurgery of vestibular schwannomas, we conducted a single-institution long-term observational study of radiosurgery for sporadic vestibular schwannomas. Minimum follow-up was 3 years. Investigated as potential predictors of tumor control and cranial nerve toxicity were treatment technology; tumor resection preceding radiosurgery; tumor size; gender; patient age; history of cancer, vascular disease, or metabolic disease; tumor volume; radiosurgical prescription dose; and isodose line. Three hundred eighty-six patients met inclusion criteria. Treatment failure was observed in 27 patients. History of unrelated cancer (strongest predictor) and prescription dose significantly predicted tumor control. The cumulative incidence of treatment failure was 30% after 6.5 years in patients with unrelated malignancy and 10% after ≥15 years in patients without such cancer (P < .02). Tumor volume was the only predictor of trigeminal neuropathy (observed in 6 patients). No predictor of facial nerve toxicity was found. On the House and Brackmann scale, 1 patient had a permanent one-level drop and 7 a transient drop of 1 to 3 levels. Serviceable hearing was preserved in 75.1%. Tumor hearing before radiosurgery, recurrence, and prescription isodose predicted ototoxicity. Unrelated malignancy is a strong predictor of tumor control. Tumor recurrence predominantly predicts ototoxicity. These findings potentially will aid future clinical decision making in ambiguous cases. PMID:22561798

Living kidney donation: outcomes, ethics, and uncertainty.

PubMed

Reese, Peter P; Boudville, Neil; Garg, Amit X

2015-05-16

Since the first living-donor kidney transplantation in 1954, more than half a million living kidney donations have occurred and research has advanced knowledge about long-term donor outcomes. Donors in developed countries have a similar life expectancy and quality of life as healthy non-donors. Living kidney donation is associated with an increased risk of end-stage renal disease, although this outcome is uncommon (<0·5% increase in incidence at 15 years). Kidney donation seems to elevate the risks of gestational hypertension and pre-eclampsia. Many donors incur financial expenses due to factors such as lost wages, need for sick days, and travel expenses. Yet, most donors have no regrets about donation. Living kidney donation is practised ethically when informed consent incorporates information about risks, uncertainty about outcomes is acknowledged when it exists, and a donor's risks are proportional to benefits for the donor and recipient. Future research should determine whether outcomes are similar for donors from developing countries and donors with pre-existing conditions such as obesity. Copyright © 2015 Elsevier Ltd.

Previous studies have demonstrated that obese patients (BMI >30) undergoing laparoscopic colectomy have longer operative times and increased complications when compared to non-obese cohorts. However, there is little data that specifically evaluates the outcomes of obese patients based on the degree of their obesity. The aim of this study was to evaluate the impact of increasing severity of obesity on patients undergoing laparoscopic colectomy. A retrospective review was performed of all patients undergoing laparoscopic colectomy between 1996 and 2013. Patients were classified according to their BMI as obese (BMI 30.0-39.9), morbidly obese (BMI 40.0-49.9), and super obese (BMI >50). Main outcome measures included conversion rate, operative time, estimated blood loss, post-operative complications, and length of stay. There were 923 patients who met inclusion criteria. Overall, 604 (65.4%), 257 (27.9%), and 62 (6.7%) were classified as obese (O), morbidly obese (MO), and super obese (SO), respectively. Clinicopathologic characteristics were similar among the three groups. The SO group had significantly higher conversion rates (17.7 vs. 7 vs. 4.8%; P = 0.031), longer average hospital stays (7.1 days vs. 4.9 vs. 3.4; P = 0.001), higher morbidity (40.3 vs. 16.3 vs. 12.4%; P = 0.001), and longer operative times (206 min vs. 184 vs. 163; P = 0.04) compared to the MO and O groups, respectively. The anastomotic leak rate in the SO (4.8%; P = 0.027) and MO males (4.1%; P = 0.033) was significantly higher than MO females (2.2%) and all obese patients (1.8%). Increasing severity of obesity is associated with worse perioperative outcomes following laparoscopic colectomy.

Prevalences of overweight and obesity among children in remote Aboriginal communities in central Australia.

2012-01-01

The chronic diseases associated with overweight and obesity are major contributors to the excess disease burden of Aboriginal Australians. Surveillance of overweight and obesity is required to monitor these conditions, and to develop and evaluate interventions to improve health and wellbeing. Remote Aboriginal communities in Australia's Northern Territory (NT) are where approximately two-thirds of the NT Aboriginal people live, a proportion which has been stable over many years. However the remote communities suffer significant socioeconomic disadvantage including limited education and employment opportunities, and poor quality and overcrowded housing. Approximately one-third of Aboriginal people in NT live in central Australia, which consists of the Alice Springs and Barkly districts. The Healthy School-Aged Kids Program includes health promotion and child health screening, and is run in remote Aboriginal communities of NT. This report provides estimates of prevalences of overweight and obesity among children in central Australia who participated in health checks as part of Healthy School-Aged Kids Program in 2010. All children in remote central Australian Aboriginal communities were invited to participate in health checks. Children who attended were weighed and measured. Date of birth, sex, height and weight for each child were used to determine prevalence of overweight (≥+1 standard deviation [SD] BMI-for-age) and obesity (≥+2 SD BMI-for-age) according to WHO Growth standards. Differences in proportions of overweight and obesity by age group and sex, and their statistical significance were calculated. Weight, height, sex and age data were available for 996 children from a population of 1764. It was found that 22.1% of girls and 20.7% of boys were overweight; and 5.1% of girls and 5.8% of boys were obese as defined by BMI-for-age. Prevalence of overweight but not obesity increased with age (for overweight z=3.28, p=0.0011; for obesity z=0.68; p=0.50). The

Obesity and the obesity paradox in heart failure.

Obesity has reached epidemic proportions in the general population and is associated with an increased risk for the development of new-onset heart failure (HF). However, in acute and chronic HF, overweight and mild to moderate obesity is associated with substantially improved survival compared with normal weight. This phenomenon has been termed the "obesity paradox" in HF. The majority of data pertaining to the obesity paradox identifies obesity with body mass index; however, the reliability of this method has been questioned. Newer studies have explored the use of other measures of body fat and body composition, including waist circumference, waist-to-hip ratio, skinfold thickness, and bioelectrical impedance analysis of body composition. The relationship between the obesity paradox and cardiorespiratory fitness in HF is also discussed in this review, and we explore the various potential explanations for the obesity paradox and summarize the current evidence and guidelines for intentional weight loss treatments for HF in the obese population.

Aquaporin 7 (AQP7) belongs to the aquaglyceroporin family, which transports glycerol and water. AQP7-deficient mice develop obesity, insulin resistance, and hyperglyceroluria. However, AQP7's pathophysiologic role in humans is not yet known. Three children with psychomotor retardation and hyperglyceroluria were screened for AQP7 mutations. The children were from unrelated families. Urine and plasma glycerol levels were measured using a three-step enzymatic approach. Platelet morphology and function were studied using electron microscopy, aggregations, and adenosine triphosphate (ATP) secretion tests. The index patients were homozygous for AQP7 G264V, which has previously been shown to inhibit transport of glycerol in Xenopus oocytes. We also detected a subclinical platelet secretion defect with reduced ATP secretion, and the absence of a secondary aggregation wave after epinephrine stimulation. Electron microscopy revealed round platelets with centrally located granules. Immunostaining showed AQP7 colocalization, with dense granules that seemed to be released after strong platelet activation. Healthy relatives of these patients, who were homozygous (not heterozygous) for G264V, also had hyperglyceroluria and platelet granule abnormalities. The discovery of an association between urine glycerol loss and a platelet secretion defect is a novel one, and our findings imply the involvement of AQPs in platelet secretion. Additional studies are needed to define whether AQP7 G264V is also a risk factor for mental disability.

Attending to unrelated targets boosts short-term memory for color arrays.

Detecting a target typically impairs performance in a second, unrelated task. It has been recently reported however, that detecting a target in a stream of distractors can enhance long-term memory of faces and scenes that were presented concurrently with the target (the attentional boost effect). In this study we ask whether target detection also enhances performance in a visual short-term memory task, where capacity limits are severe. Participants performed two tasks at once: a one shot, color change detection task and a letter-detection task. In Experiment 1, a central letter appeared at the same time as 3 or 5 color patches (memory display). Participants encoded the colors and pressed the spacebar if the letter was a T (target). After a short retention interval, a probe display of color patches appeared. Performance on the change detection task was enhanced when a target, rather than a distractor, appeared with the memory display. This effect was not modulated by memory load or the frequency of trials in which a target appeared. However, there was no enhancement when the target appeared at the same time as the probe display (Experiment 2a) or during the memory retention interval (Experiment 2b). Together these results suggest that detecting a target facilitates the encoding of unrelated information into visual short-term memory. Copyright © 2010 Elsevier Ltd. All rights reserved.

Reproductive concessions between related and unrelated members promote eusociality in bees.

Andrade, Aline C R; Miranda, Elder A; Del Lama, Marco A; Nascimento, Fábio S

2016-05-23

Animal societies exhibit remarkable variation in their breeding strategies. Individuals can maximize their fitness by either reproducing or by helping relatives. Social hymenopterans have been key taxa for the study of Hamilton's inclusive fitness theory because the haplodiploid sex-determination system results in asymmetric relatedness among breeders producing conflict over the partitioning of reproduction. In small cooperative groups of insects, totipotent individuals may maximize their inclusive fitness by controlling reproduction despotically rather than helping their relatives. Here, we demonstrate that the dominant females of the primitively eusocial bee Euglossa melanotricha (Apidae: Euglossini) control reproduction, but concede part of the reproductive output with their related and unrelated subordinates. As expected, a dominant female capitalizes on the direct reproduction of related subordinates, according to her interests. We found that reproductive skew was positively correlated with relatedness. The concessions were highly reduced in mother-daughter and sibling nests (relatedness r ± s.d. = 0.54 ± 0.02 and 0.79 ± 0.02, respectively) but much more egalitarian in unrelated associations (r = -0.10 ± 0.01). We concluded that reproductive skew in these primitively eusocial bees is strongly related to the genetic structure of associations, and also that females are able to assess pairwise relatedness, either directly or indirectly, and use this information to mediate social contracts.

The lived experiences of being physically active when morbidly obese: A qualitative systematic review

The aim is to identify facilitators and barriers for physical activity (PA) experienced by morbidly obese adults in the Western world. Inactivity and a sedentary lifestyle have become a major challenge for health and well-being, particularly among persons with morbid obesity. Lifestyle changes may lead to long-term changes in activity level, if facilitators and barriers are approached in a holistic way by professionals. To develop lifestyle interventions, the perspective and experiences of this group of patients are essential for success. The methodology of the systematic review followed the seven-step procedure of the Joanna Briggs Institute and was published in a protocol. Six databases were searched using keywords and index terms. Manual searches were performed in reference lists and in cited citations up until March 2015. The selected studies underwent quality appraisal in the Joanna Briggs-Qualitative Assessment and Review Instrument. Data from primary studies were extracted and were subjected to a hermeneutic text interpretation and a data-driven coding in a five-step procedure focusing on meaning and constant targeted comparison through which they were categorized and subjected into a meta-synthesis. Eight papers were included for the systematic review, representing the experiences of PA among 212 participants. One main theme developed from the meta-data analysis: “Identity” with the three subthemes: “considering weight,” “being able to,” and “belonging with others.” The theme and subthemes were merged into a meta-synthesis: “Homecoming: a change in identity.” The experiences of either suffering or well-being during PA affected the identity of adults with morbid obesity either by challenging or motivating them. A change in identity may be needed to feel a sense of “homecoming” when active. PMID:26400462

We investigated associations of acculturation with various types of activity (moderate-vigorous leisure-time physical activity [LTPA], moderate-vigorous work- and transportation-related physical activity, and sedentary activity), and whether these activities mediated the acculturation-obesity association among Mexican-Americans. Cross-sectional. National Health and Nutrition Examination Survey (NHANES) 2007-2010. Mexican-American NHANES participants aged ≥20 years (n = 1902). Demographic characteristics, physical activity, sedentary behavior, acculturation, and body mass index. Multinomial logistic regression was used to estimate associations of acculturation with categories of self-reported activity. Path analysis was used to test whether the activity measures mediated acculturation-obesity associations. In adjusted models, compared to U.S.-born Mexican-Americans, foreign-born Mexican-Americans living in the United States for less than 10 years were significantly less likely to be in the highest LTPA and sedentary activity categories, and more likely to be in the highest total and transportation activity categories. Foreign-born Mexican-Americans living in the United States for 10 years or more were significantly less likely to engage in high sedentary activity but more likely to engage in high transportation activity. Sedentary behavior was the strongest mediator of the acculturation-obesity association, accounting for 40.7% and 57.1% of the total effect of acculturation on obesity among foreign-born Mexican-Americans living in the United States for less than 10 years and for 10 years or more, respectively, compared to U.S.-born Mexican-Americans. Reducing sedentary behavior may lower the negative impact of acculturation on obesity.

A cross-sectional study was designed to understand the impacts of “hikikomori” lifestyle on physical health. A total of 104 eligible hikikomori cases were recruited from the social services network of Hong Kong with a mean age of 19.02 ± 3.62 (ranged 13–31) year-old, and had completed the set of questionnaires and a series of anthropometric and physical health measurements. Despite SF36 score of 84.0 indicated good physical functioning in general, participants were lived sedentarily with high incidence of hypertension at 15.4% and prehypertension at 31.7%. Occurrence of hypertension and prehypertension in cases living as hikikomori >6 months were 3 times and 1.5 times higher than those newly onset cases, respectively. The blood pressure levels were correlated with age and all obesity index parameters measured including waist circumference and body mass index. Results also observed a shift of body weight from underweight to overweight and obesity along the hikikomori duration. Half of the hypertensive cases involved the elevation of systolic blood pressure, which suggested higher odds of cardiovascular complications. In conclusion, the hikikomori lifestyle could be a risk behavior that may harm the younger generation physically by promoting obesity and hypertension and probably other chronic illnesses.

This article describes how the Children's Healthy Living (CHL) Program used the ANGELO (Analysis Grid for Environments/Elements Linked to Obesity) model to design a regional intervention to increase fruit and vegetable intake, water consumption, physical activity, and sleep duration and decrease recreational screen time and sugar-sweetened beverage consumption in young children ages 2–8 years. Methods: Using the ANGELO model, CHL (1) engaged community to identify preferred intervention strategies, (2) reviewed scientific literature, (3) merged findings from community and literature, and (4) formulated the regional intervention. Results: More than 900 community members across the Pacific helped identify intervention strategies on importance and feasibility. Nine common intervention strategies emerged. Participants supported the idea of a regional intervention while noting that cultural and resource differences would require flexibility in its implementation in the five jurisdictions. Community findings were merged with the effective obesity-reducing strategies identified in the literature, resulting in a regional intervention with four cross-cutting functions: (1) initiate or strengthen school wellness policies; (2) partner and advocate for environmental change; (3) promote CHL messages; and (4) train trainers to promote CHL behavioral objectives for children ages 2–8 years. These broad functions guided intervention activities and allowed communities to tailor activities to maximize intervention fit. Conclusions: Using the ANGELO model assured that the regional intervention was evidence based while recognizing jurisdiction context, which should increase effectiveness and sustainability.

Obesity prevalence in the United States appears to be leveling, but the reasons behind the plateau remain unknown. Mechanistic insights can be provided from a mathematical model. The objective of this study is to model known multiple population parameters associated with changes in body mass index (BMI) classes and to establish conditions under which obesity prevalence will plateau. A differential equation system was developed that predicts population-wide obesity prevalence trends. The model considers both social and nonsocial influences on weight gain, incorporates other known parameters affecting obesity trends, and allows for country specific population growth. The dynamic model predicts that: obesity prevalence is a function of birthrate and the probability of being born in an obesogenic environment; obesity prevalence will plateau independent of current prevention strategies; and the US prevalence of overweight, obesity, and extreme obesity will plateau by about 2030 at 28%, 32%, and 9% respectively. The US prevalence of obesity is stabilizing and will plateau, independent of current preventative strategies. This trend has important implications in accurately evaluating the impact of various anti-obesity strategies aimed at reducing obesity prevalence. Copyright © 2013 The Obesity Society.

Promoting active living in healthy cities of Europe.

Faskunger, Johan

2013-10-01

Local governments in Europe have a vital role in promoting physical activity in the daily life of citizens. However, explicit investment in active living has been limited. One of the four core themes for Phase IV (2003-2008) of the World Health Organization (WHO) European Healthy Cities Network (WHO-EHCN) was to encourage local governments and their partners to implement programs in favor of active living. This study analyzes the performance of network cities during this period. Responses to a general evaluation questionnaire are analyzed by content according to a checklist, and categorized into themes and dimensions. Most cities viewed "active living" as an important issue for urban planning; to improve visual appeal, enhance social cohesion, create a more sustainable transport system to promote walkability and cyclability and to reduce inequalities in public health. Almost all member cities reported on existing policies that support the promotion of active living. However, only eight (of the 59) responding cities mentioned an integrated framework specific for active living. Many efforts to promote active living are nested in programs to prevent obesity among adults or children. Future challenges include establishing integrated policies specifically for active living, introducing a larger range of actions, as well as increasing funding and capacity to make a difference at the population level.

A Unified Approach to Genotype Imputation and Haplotype-Phase Inference for Large Data Sets of Trios and Unrelated Individuals

Browning, Brian L.; Browning, Sharon R.

2009-01-01

We present methods for imputing data for ungenotyped markers and for inferring haplotype phase in large data sets of unrelated individuals and parent-offspring trios. Our methods make use of known haplotype phase when it is available, and our methods are computationally efficient so that the full information in large reference panels with thousands of individuals is utilized. We demonstrate that substantial gains in imputation accuracy accrue with increasingly large reference panel sizes, particularly when imputing low-frequency variants, and that unphased reference panels can provide highly accurate genotype imputation. We place our methodology in a unified framework that enables the simultaneous use of unphased and phased data from trios and unrelated individuals in a single analysis. For unrelated individuals, our imputation methods produce well-calibrated posterior genotype probabilities and highly accurate allele-frequency estimates. For trios, our haplotype-inference method is four orders of magnitude faster than the gold-standard PHASE program and has excellent accuracy. Our methods enable genotype imputation to be performed with unphased trio or unrelated reference panels, thus accounting for haplotype-phase uncertainty in the reference panel. We present a useful measure of imputation accuracy, allelic R2, and show that this measure can be estimated accurately from posterior genotype probabilities. Our methods are implemented in version 3.0 of the BEAGLE software package. PMID:19200528

Childhood obesity in rural communities is a serious but understudied problem. The current experiment aims to assess a wide range of obesity risk factors among rural youth and to offer an 8-month intervention program for parents to reduce obesity risk in their preteen child. A two-group, repeated measures design is used to assess the effectiveness of the 4-Health intervention program. Assessments include anthropometric measures, child self-evaluations, parent self-evaluations, and parent evaluations of child. County Extension agents from 21 rural Montana counties recruit approximately 150 parent-child dyads and counties are semi-randomly assigned to the active intervention group (4-Health Educational Program) or a "best-practices" (Healthy Living Information) control group. This study will shed light on the effectiveness of this parent-only intervention strategy in reducing obesity risk factors among rural preteens. The 4-Health program is designed to provide information and skills development for busy rural parents that will increase healthy lifestyles of their preteen children and improve the parents' ability to intervene effectively in the lives of their families during this critical developmental period.

To evaluate the role of a second allogeneic hematopoietic stem-cell transplantation (HSCT2) given for relapsed acute leukemia (AL) after related or unrelated first hematopoietic stem-cell transplantation (HSCT1) and to analyze the role of donor change for HSCT2 in both settings. We performed a retrospective registry study on 179 HSCT2s given for relapse after HSCT1 from matched related donors (n = 75) or unrelated donors (n = 104), using identical or alternative donors for HSCT2. Separate analyses were performed according to donor at HSCT1. Independent of donor, 74% of patients achieved complete remission after HSCT2, and half of these patients experienced relapse again. Overall survival (OS) at 2 years was 25% ± 4% (39% ± 7% after related HSCT2; 19% ± 4% after unrelated HSCT2). Long-term survivors were observed even after two unrelated HSCT2s. Multivariate analysis for OS from HSCT2 confirmed established risk factors (remission duration after HSCT1: hazard ratio [HR], 2.37; 95% CI, 1.61 to 3.46; P < .001; stage at HSCT2: HR, 0.53; 95% CI, 0.34 to 0.83; P = .006). Outcome of HSCT2 was better after related HSCT1 than after unrelated HSCT1 (2-year OS: 37% ± 6% v 16% ± 4%, respectively; HR, 0.68; 95% CI, 0.47 to 0.98; P = .042, multivariate Cox regression). After both related and unrelated HSCT1, selecting a new donor for HSCT2 did not result in a relevant improvement in OS compared with HSCT2 from the original donor; however, donor change was not detrimental either. After relapse from allogeneic HSCT1, HSCT2 can induce 2-year OS in approximately 25% of patients. Unrelated HSCT2 is feasible after related and unrelated HSCT1. Donor change for HSCT2 is a valid option. However, a clear advantage in terms of OS could not be demonstrated.

Predicting adult obesity from childhood obesity: a systematic review and meta-analysis.

2016-02-01

A systematic review and meta-analysis was performed to investigate the ability of simple measures of childhood obesity such as body mass index (BMI) to predict future obesity in adolescence and adulthood. Large cohort studies, which measured obesity both in childhood and in later adolescence or adulthood, using any recognized measure of obesity were sought. Study quality was assessed. Studies were pooled using diagnostic meta-analysis methods. Fifteen prospective cohort studies were included in the meta-analysis. BMI was the only measure of obesity reported in any study, with 200,777 participants followed up. Obese children and adolescents were around five times more likely to be obese in adulthood than those who were not obese. Around 55% of obese children go on to be obese in adolescence, around 80% of obese adolescents will still be obese in adulthood and around 70% will be obese over age 30. Therefore, action to reduce and prevent obesity in these adolescents is needed. However, 70% of obese adults were not obese in childhood or adolescence, so targeting obesity reduction solely at obese or overweight children needs to be considered carefully as this may not substantially reduce the overall burden of adult obesity. © 2015 World Obesity.

GENETIC EVOLUTION OF BACTERIOPHAGE, I. HYBRIDS BETWEEN UNRELATED BACTERIOPHAGES P22 AND FELS 2*

PubMed Central

Yamamoto, Nobuto

1969-01-01

A new bacteriophage species, designated F22, was isolated from phage P22 stocks grown on Salmonella typhimurium Q1 lysogenic for Fels 2 at a frequency of less than 10-11. P22 has a very short tail with a hexagonal base plate and six spikes. Phage Fels 2 is morphologically similar to E. coli T-even phages, having a long tail with a contractile sheath and carrying no genetic region related to P22. Phage F22 is morphologically and serologically indistinguishable from Fels 2, but carries the c(c1, c2, and c3) markers of P22. The color markers h21, g, and m3 of P22 do not appear in F22. Thus, F22 is evidently a recombinant between the unrelated bacteriophages P22 and Fels 2. The recombination between unrelated bacteriophages could play an important role in the evolution of bacteriophages. Images PMID:4890254

Background Prevalence rates of cardiometabolic risk factors vary largely among overweight children. This study investigated the relationships between dietary habits and cardiometabolic health among obese children living in a city of Northern Italy. Methods Dietary habits were collected in 448 obese subjects aged 6-18 years, attending an obesity outpatient center in Milan. Anthropometry, blood pressure (BP), lipids, fasting and post-load glucose, and insulin were measured. Physical activity was assessed in adolescents using a questionnaire. Results Frequency of glucose intolerance, hypertension and dyslipidemia was 0.7%, 13% and 27.2%, respectively. Plausible reporters consumed more animal protein and sodium and less legumes than recommended in nutritional recommendations and adequate amounts of fiber mainly derived from whole grains. Subjects skipping breakfast had unhealthy diets and greater body fatness. After adjustment for confounders, waist/height and fasting glucose were associated with sodium intake (r =0.149 and r = 0.142, respectively; p < 0.05), 2-hour glucose with fiber (r = −0.172; p < 0.01), and BP with vegetable protein intake (systolic r = −0.120 (p < 0.05); diastolic r = −0.267 (p < 0.01)). Hypertensive children consumed less vegetable protein than normotensive children. Conclusions The cardiometabolic health of obese children improves with vegetable protein and whole grain intake, whereas dysglycemia and adiposity increase with sodium intake. PMID:26087840

Can exclusive breastfeeding reduce the likelihood of childhood obesity in some regions of Canada?

The prevalence of childhood obesity in Canada is a major concern. Studies report a small but significant inverse relationship between exclusive breastfeeding and childhood obesity. The study objectives were to determine the prevalence of overweight and obesity in a preschool population living in Newfoundland and Labrador (NL) and to examine the relationship between exclusive breastfeeding and preschool obesity. This was a cross-sectional analysis of 1,026 children born in 2001 who participated in the Pre Kindergarten Health Fairs in 2005. Heights and weights were collected and body mass index (BMI) calculated. The BMI-for-age references used by the Centers for Disease Control (CDC) in the United States were used to classify the weight status of children. Infant feeding information was collected through a survey. The relationship between breastfeeding and childhood obesity was examined using logistic regression models controlling for child's age and gender, mother's education and smoking status, and whether the baby was preterm or full-term. In 2005, 65%, 19% and 16% of preschool children were normal, overweight and obese, respectively. 74% of women initiated breastfeeding and 43% exclusively breastfed to 3 months. Exclusive breastfeeding to 3 months was protective of preschool obesity (adjusted odds ratio (AOR) 0.65, 95% CI 0.45-0.96). Obesity is prevalent in preschool children in NL. Exclusive breastfeeding appeared to be a protective factor for obesity in preschoolers. Given the known benefits of breastfeeding and the adverse health consequences of obesity, efforts should be made to increase exclusive breastfeeding which may help to prevent the development of obesity in young children.

Obesity management: what brings success?

The upward trend in obesity prevalence across regions and continents is a worldwide concern. Today a majority of the world’s population live in a country where being overweight or obese causes more deaths than being underweight. Only a portion of those qualifying for treatment will get the health care they need. Still, a minor weight loss of 5–10% seems to be sufficient to provide a clinically significant health benefit in terms of risk factors for cardiovascular disease and diabetes. Diet, exercise and behavior modifications remain the current cornerstones of obesity treatment. Weight-loss drugs play a minor role. Drugs which were available and reasonably effective have been withdrawn because of side effects. The fact that the ‘old’ well known, but pretty unexciting tools remain the basic armamentarium causes understandable concern and disappointment among both patients and therapists. Hence, bariatric surgery has increasingly been recognized and developed, as it offers substantial weight loss and prolonged weight control. The present review highlights the conventional tools to counter obesity, lifestyle modification, pharmacotherapy and bariatric surgery, including some of the barriers to successful weight loss: (1) unrealistic expectations of success; (2) high attrition rates; (3) cultural norms of self-acceptance in terms of weight and beliefs of fat being healthy; (4) neighborhood attributes such as a lack of well-stocked supermarkets and rather the presence of convenience stores with low-quality foods; and (5) the perception of the neighborhood as less safe and with low walkability. Prevention is the obvious key. Cost-effective societal interventions such as a tax on unhealthy food and beverages, front-of-pack traffic light nutrition labeling and prohibition of advertising of junk food and beverages to children are also discussed.

Semantic relation vs. surprise: the differential effects of related and unrelated co-verbal gestures on neural encoding and subsequent recognition.

Speech-associated gesturing leads to memory advantages for spoken sentences. However, unexpected or surprising events are also likely to be remembered. With this study we test the hypothesis that different neural mechanisms (semantic elaboration and surprise) lead to memory advantages for iconic and unrelated gestures. During fMRI-data acquisition participants were presented with video clips of an actor verbalising concrete sentences accompanied by iconic gestures (IG; e.g., circular gesture; sentence: "The man is sitting at the round table"), unrelated free gestures (FG; e.g., unrelated up down movements; same sentence) and no gestures (NG; same sentence). After scanning, recognition performance for the three conditions was tested. Videos were evaluated regarding semantic relation and surprise by a different group of participants. The semantic relationship between speech and gesture was rated higher for IG (IG>FG), whereas surprise was rated higher for FG (FG>IG). Activation of the hippocampus correlated with subsequent memory performance of both gesture conditions (IG+FG>NG). For the IG condition we found activation in the left temporal pole and middle cingulate cortex (MCC; IG>FG). In contrast, for the FG condition posterior thalamic structures (FG>IG) as well as anterior and posterior cingulate cortices were activated (FG>NG). Our behavioral and fMRI-data suggest different mechanisms for processing related and unrelated co-verbal gestures, both of them leading to enhanced memory performance. Whereas activation in MCC and left temporal pole for iconic co-verbal gestures may reflect semantic memory processes, memory enhancement for unrelated gestures relies on the surprise response, mediated by anterior/posterior cingulate cortex and thalamico-hippocampal structures.

How Effective Are Antioxidant Supplements in Obesity and Diabetes?

PubMed Central

Abdali, Daniyal; Samson, Sue E.; Grover, Ashok Kumar

2015-01-01

Obesity is a central health issue due to its epidemic prevalence and its association with type 2 diabetes and other comorbidities. Obesity is not just being overweight. It is a metabolic disorder due to the accumulation of excess dietary calories into visceral fat and the release of high concentrations of free fatty acids into various organs. It represents a state of chronic oxidative stress and low-grade inflammation whose intermediary molecules may include leptin, adiponectin and cytokines. It may progress to hyperglycemia, leading to type 2 diabetes. Whether or not dietary antioxidant supplements are useful in the management of obesity and type 2 diabetes is discussed in this review. Only the benefits for obesity and diabetes are examined here. Other health benefits of antioxidants are not considered. There are difficulties in comparing studies in this field because they differ in the time frame, participants' ethnicity, administration of antioxidant supplements, and even in how obesity was measured. However, the literature presents reasonable evidence for marginal benefits of supplementation with zinc, lipoic acid, carnitine, cinnamon, green tea, and possibly vitamin C plus E, although the evidence is much weaker for omega-3 polyunsaturated fatty acids, coenzyme Q10, green coffee, resveratrol, or lycopene. Overall, antioxidant supplements are not a panacea to compensate for a fast-food and video-game way of living, but antioxidant-rich foods are recommended as part of the lifestyle. Such antioxidant foods are commonly available. PMID:25791371

Context: Obese men with normal semen parameters exhibit reduced fertility but few prospective data are available. Objective: This study aimed to determine the effect of male factors and body mass among the Pregnancy in Polycystic Ovary Syndrome II (PPCOS II) participants. Methods: This is a secondary analysis of the PPCOS II trial. A total of 750 infertile women with polycystic ovary syndrome (PCOS) were randomly assigned to up to receive five cycles of letrozole or clomiphene citrate. Females were 18–39-years-old and had a male partner with sperm concentration of at least 14 million/mL who consented to regular intercourse. Analysis was limited to couples with complete male partner information (n = 710). Results: Male body mass index (BMI) was higher in couples who failed to conceive (29.5 kg/m2 vs 28.2 kg/m2; P = .039) as well as those who did not achieve a live birth (29.5 kg/m2 vs 28.1 kg/m2; P = .047). At least one partner was obese in 548 couples (77.1%). A total of 261 couples were concordant for obesity (36.8%). After adjustment for female BMI, the association of male BMI with live birth was no longer significant (odds ratio [OR] = 0.85; 95 % confidence interval [CI], 0.68–1.05; P = .13). Couples in which both partners smoked had a lower chance of live birth vs nonsmokers (OR = 0.20; 95 % CI, 0.08–0.52; P = .02), whereas there was not a significant effect of female or male smoking alone. Live birth was more likely in couples with at least three sexual intercourse attempts over the previous 4 weeks (reported at baseline) as opposed to couples with lesser frequency (OR = 4.39; 95 % CI, 1.52–12. 4; P < .01). Conclusions: In this large cohort of obese women with PCOS, effect of male obesity was explained by female BMI. Lower chance of success was seen among couples where both partners smoked. Obesity and smoking are common among women with PCOS and their partners and contribute to a decrease in fertility treatment success. PMID:25856211

Childhood obesity is an increasing concern for parents and health professionals alike. Parents' perception of obesity as a current health issue for their children is important for the everyday parenting and health choices parents make. As parents are frequently going online to seek and exchange information about parenting and child health, asynchronous online discussion forums provide an opportunity to investigate their perceptions and concerns. Understanding parents' perceptions, beliefs and attitudes is important in any childhood obesity prevention and intervention. To explore parents' perceptions, perspectives and concerns regarding childhood obesity expressed on asynchronous online discussion forums. A qualitative descriptive approach using template analysis to analyse a novel data collection strategy of 34 purposefully sampled threads from two Australian-based asynchronous online discussion forums. Parents on the discussion forum displayed an understanding of childhood obesity as a public health concern, the discussion incorporated issues such as providing a healthy diet and lifestyle for children. Parents shared their own opinions and experiences that challenged or conceded to the status quo of the discussion. Parents discussed the role of health professionals in obesity prevention. There were varied opinions on the relevance of health professionals, particularly nurses, monitoring of growth and risk of obesity. This exploratory study highlights that parents perceive childhood obesity as an important public health concern, and that they understand the key public health messages of prevention and intervention. Yet, for many it is difficult to successfully implement these messages into their everyday lives. Health professionals need to play a key role in providing non-judgemental, innovative support and advice to parents to successfully implement prevention and intervention strategies.

People who are overweight or have obesity are estimated to comprise 30% of the global population and up to 59% of companion dogs and cats are estimated to be above their optimal body weight. The prevalence of human and companion obesity is increasing. The direct and indirect costs of obesity and associated comorbidities are significant for human and veterinary healthcare. There are numerous similarities between obesity in people and companion animals, likely related to the shared environmental and lifestyle elements of this multifactorial disease. While the study of human obesity is relatively robust, research conducted in pets is generally limited to small studies, studies with cross-sectional designs or reports that have yet to be replicated. Greater understanding of human obesity may elucidate some of the factors driving the more recent rise in pet obesity. In particular, there are overlapping features of obesity in children and pets that are, in part, related to dependency on their 'parents' for care and feeding. When feeding is used in a coercive and controlling fashion, it may lead to undesirable feeding behaviour and increase the risk for obesity. A 'responsive parenting' intervention teaches parents to respond appropriately to hunger-satiety cues and to recognize and respond to others' distress. Such interventions may impact on childhood overweight and obesity and have the potential to be adapted for use with companion animals. Social behaviour towards people with obesity or owners of pets with obesity is often driven by beliefs about the cause of the obesity. Educating healthcare professionals and the public about the multifactorial nature of this complex disease process is a fundamental step in reducing the bias and stigma associated with obesity. Children living in low-income households have particularly high rates of obesity and as household income falls, rates of obesity also rise in pets and their owners. There are risk regulators (i.e. dynamic

Objective Obesity, which is frequently associated with diabetes, hypertension, and cardiovascular diseases, is primarily the result of a net excess of caloric intake over energy expenditure. Human obesity is highly heritable, but the specific genes mediating susceptibility in non-syndromic obesity remain unclear. We tested candidate genes in pathways related to food intake and energy expenditure for association with body mass index (BMI). Methods We re-analyzed 355 common genetic variants of 30 candidate genes in 7 molecular pathways related to obesity in 1,982 unrelated European Americans from the New York Health Project. Data were analyzed by using a Bayesian hierarchical generalized linear model. The BMIs were log-transformed and then adjusted for covariates including age, age2, gender, and diabetes status. The single nucleotide polymorphisms (SNPs) were modeled as additive effects. Results With the stipulated adjustments, nine SNPs in eight genes were significantly associated with BMI: GHRL (rs35683), AGRP (rs5030980), CPE (rs1946816 and rs4481204), GLP1R (rs2268641), HTR2A (rs912127), NPY5R (Y5R1c52), SOCS3 (rs4969170), and STAT3 (rs4796793). We also found a gender-by-SNP interaction (rs1745837 in HTR2A), which indicated that variants in the gene HTR2A had a stronger association with BMI in males. In addition, NPY1R was detected as having a significant gene effect even though none of the SNPs in this gene was significant. Conclusion Variations in genes AGRP, CPE, GHRL, GLP1R, HTR2A, NPY1R, NPY5R, SOCS3, and STAT3 showed modest associations with BMI in European Americans. The pathways in which these genes participate regulate energy intake and thus these associations are mechanistically plausible in this context. PMID:23900445

Obesity is more prevalent and its consequences severe among middle-aged and older adults. Efforts to understand and address neighborhood-level causes of obesity in this population offer the potential to enhance health and reduce the costs of obesity for everyone. The accompanying paper by Li et al. (Am J Epidemiol. 2009;169(4):401–408) presents new data on the apparently significant interaction between neighborhood and individual characteristics on 1-year change in body weight and waist circumference. Despite methodological limitations in measurement, this paper supports the importance of future research that considers the complex relation between people and where they live. Efforts to design neighborhood-level policy interventions to effectively address the problem of obesity will require greater interdisciplinary collaboration. PMID:19153213

Latinos are the largest and fastest-growing ethnically diverse group in the U.S.; they are also the most overweight. Mexico is now second to the U.S. in experiencing the worst epidemic of obesity in the world. Objectives of this study were to (1) conduct a systematic review of obesity-related interventions targeting Latinos living in the U.S. and Latin America and (2) develop evidence-based recommendations to inform culturally relevant strategies targeting obesity. Obesity-related interventions, published between 1965 and 2010, were identified through searches of major electronic databases in 2010-2011. Selection criteria included evaluation of obesity-related measures; intervention conducted in a community setting; and at least 50.0% Latino/Latin American participants, or with stratified results by race/ethnicity. Body of evidence was based on the number of available studies, study design, execution, and effect size. Of 19,758 articles, 105 interventions met final inclusion criteria. Interventions promoting physical activity and/or healthy eating had strong or sufficient evidence for recommending (1) school-based interventions in the U.S. and Latin America; (2) interventions for overweight or obese children in the healthcare context in Latin America; (3) individual-based interventions for overweight or obese adults in the U.S.; (4) individual-based interventions for adults in Latin America; and (5) healthcare-based interventions for overweight or obese adults in Latin America. Most intervention approaches combined physical activity and healthy eating to address both sides of the energy-balance equation. Results can help guide comprehensive evidence-based efforts to tackle the obesity epidemic in the U.S. and Latin America. Copyright © 2013 American Journal of Preventive Medicine.

Adulthood overweight and obesity are multifaceted conditions influenced by a combination of biological, environmental and socio-cultural factors across the lifespan. Using a longitudinal study design, we aimed to identify determinants of adulthood overweight and obesity, in relation to: 1) childhood and life course factors, 2) geographical differences in air quality, and 3) gender-specific factors, in a cohort followed from childhood into adulthood. Childhood data were acquired (1978-1986) from children residing in four distinct Hamilton neighbourhoods (Ontario, Canada), including air-quality assessments. Adulthood data were obtained (2006-2007) from successfully retraced participants (n = 315) using comprehensive self-administered questionnaires. Multivariate logistic regressions were used to evaluate determinants of adulthood overweight (BMI: 25-29.9 kg/m2) and obesity (BMI: ≥30). The prevalence of normal weight decreased drastically at follow-up in adulthood, while that of overweight and obesity increased. Both overweight and obesity in adulthood were associated with male gender and occupational exposures to contaminants. Childhood residence in Hamilton neighbourhoods with better air quality was associated with lesser odds of adulthood overweight, whereas adulthood obesity was strongly linked to childhood weight gain (overweight or obesity). Among females, childhood weight status predicted overweight and obesity in adulthood, with always living in Hamilton, lack of additional health insurance, negative self-appraisal and high blood pressure during adulthood identified as other significant predictors. Among males, prolonged occupational exposures to contaminants emerged as a unique determinant of adulthood weight gain. Adulthood overweight and obesity are associated with childhood and life course determinants, including childhood weight status, residential air quality and occupational contaminant exposures, in a gender-specific manner.

U.S. adults with intellectual and developmental disabilities (IDD) have poorer health status and greater risks for being overweight and obese, which are major drivers of health care expenditures in the general population. Health care expenditures and IDD have not been studied using nationally representative samples, and the impact of overweight and obesity have not been examined. Using nationally representative data, we aimed to compare the health care expenditures of not-overweight, overweight and obese U.S. adults with IDD, and calculate model-adjusted expenditures. Pooled data from the 2002-2011 Medical Expenditure Panel Survey linked to National Health Interview Survey (n = 1224) were analyzed. Two-part model regressions were conducted, with covariates being year of survey, age, sex, race/ethnicity, household income status, geographical region, urban/rural, marital status, insurance coverage, perceived health status, and perceived mental health status. Overall, obese adults with intellectual and developmental disabilities had higher expenditures than their non-obese peers. Being obese was associated with an estimated additional $2516 in mean expenditures and $1200 in median expenditures compared with the reference group, who were neither overweight nor obese. Obesity is an important predictor of higher health care costs among community-living adults with IDD Finding effective strategies and interventions to address obesity in this population has great financial and policy significance.

Objective To examine whether the adverse effect of obesity on psychological well‐being can be explained by weight discrimination. Methods The study sample included 5056 older (≥50 y) men and women living in England and participating in the English Longitudinal Study of Ageing. Participants reported experiences of weight discrimination in everyday life and completed measures of quality of life (CASP‐19 scale), life satisfaction (Satisfaction With Life Scale), and depressive symptoms (eight‐item CES‐D scale). Height and weight were objectively measured, with obesity defined as BMI ≥30 kg/m2. Mediation analyses were used to test the role of perceived weight discrimination in the relationship between obesity and each psychological factor. Results Obesity, weight discrimination, and psychological well‐being were all significantly inter‐related. Mediation models revealed significant indirect effects of obesity through perceived weight discrimination on quality of life (β = −0.072, SE = 0.008), life satisfaction (β = −0.038, SE = 0.008), and depressive symptoms (β = 0.057, SE = 0.008), with perceived weight discrimination explaining approximately 40% (range: 39.5‐44.1%) of the total association between obesity and psychological well‐being. Conclusions Perceived weight discrimination explains a substantial proportion of the association between obesity and psychological well‐being in English older adults. Efforts to reduce weight stigma in society could help to reduce the psychological burden of obesity. PMID:25809860

This cross-sectional study examined the: (1) association between food store environment (FSE), fruit and vegetable (FV) availability and access, and prevalence of early childhood overweight/obesity (COWOB); and (2) influence of young child actual FV intake on the relationship between the FSE and early COWOB prevalence. Anthropometric and socio-demographic data of children (2 to 8 years; N=466) in baseline communities on Guam participating in the Children's Healthy Living (CHL) Program community trial were included. CDC year 2000 growth charts were used to calculate BMI z-scores and categories. FSE factors (fresh FV scores, store type) were assessed using the CX3 Food Availability and Marketing Survey amended for CHL. ArcGIS maps were constructed with geographic coordinates of participant residences and food stores to calculate food store scores within 1 mile of participant's residences. A sub-sample of participants (n = 355) had Food and Activity Log data to calculate FV and energy intakes. Bivariate correlations and logistic regression evaluated associations. Of 111 stores surveyed, 73% were small markets, 16% were convenience stores, and 11% were large grocery/supermarkets. Supermarkets/large grocery stores averaged the highest FV scores. Most participants did not meet FV intake recommendations while nearly half exceeded energy intake recommendations. Living near a small market was negatively correlated with BMI z-score (r = - 0.129, P < .05) while living near a convenience store was positively correlated with BMI z-score (r = 0.092, P < .05). Logistic regression analysis yielded non-significant associations. The high density of small markets may be an opportunity for FSE intervention but further investigation of Guam's FSE influence on health is needed. PMID:28808612

In search of the silver bullet: regulatory models to address childhood obesity.

Rothenberg, Joan R

2010-01-01

The concern over obesity today has evolved beyond an issue of personal vanity to a serious national health issue affecting millions of Americans. Obesity in children is especially alarming. Overweight children and adolescents are at risk for health problems throughout their lives. While under-nutrition or diet insufficiencies were once major obstacles in the development of healthy infants and children, the epidemic of childhood obesity marks the start of the 21st century with equally menacing health consequences. Childhood obesity creates an increased burden of disease on our economy with increased indirect economic costs of time lost from work for parents and time lost from school for the child. Data raise the possibility that the current generation of children could suffer greater illness or experience a shorter lifespan than that of their parents. Some experts believe that government mandated restrictions on dietary choices would alleviate the obesity problem, while others find such actions to be an unwarranted government intrusion. Still, as concerns about obesity continue to grow, especially regarding children, some say government intervention of some type is necessary to solve the problem. This paper examines the history and factors involved in the childhood obesity epidemic, explores regulatory options for its resolution, and provides an overview of obesity as a serious challenge to public health, and the health of children in particular. The federal agencies who share the responsibility for regulating food in the United States and their efforts to address the obesity problem are discussed as a background to various state and federal regulatory models influencing dietary choices. The effectiveness of proposed regulations and alternatives to government intervention suggest that the resolution of the childhood obesity issue requires a coordinated, multilevel approach.

Background Outside of the United States, evidence for associations between exposure to fast-food establishments and risk for obesity among adults is limited and equivocal. The purposes of this study were to investigate whether the relative availability of different types of food retailers around people's homes was associated with obesity among adults in Edmonton, Canada, and if this association varied as a function of distance between food locations and people's homes. Methods Data from a population health survey of 2900 adults (18 years or older) conducted in 2002 was linked with geographic measures of access to food retailers. Based upon a ratio of the number of fast-food restaurants and convenience stores to supermarkets and specialty food stores, a Retail Food Environment Index (RFEI) was calculated for 800 m and 1600 m buffers around people's homes. In a series of logistic regressions, associations between the RFEI and the level of obesity among adults were examined. Results The median RFEI for adults in Edmonton was 4.00 within an 800 m buffer around their residence and 6.46 within a 1600 m buffer around their residence. Approximately 14% of the respondents were classified as being obese. The odds of a resident being obese were significantly lower (OR = 0.75, 95%CI 0.59 – 0.95) if they lived in an area with the lowest RFEI (below 3.0) in comparison to the highest RFEI (5.0 and above). These associations existed regardless of the covariates included in the model. No significant associations were observed between RFEI within a 1600 m buffer of the home and obesity. Conclusion The lower the ratio of fast-food restaurants and convenience stores to grocery stores and produce vendors near people's homes, the lower the odds of being obese. Thus the proximity of the obesogenic environment to individuals appears to be an important factor in their risk for obesity. PMID:19538709

Neighbourhood economic deprivation explains racial/ethnic disparities in overweight and obesity among children and adolescents in the U.S.A.

PubMed

Rossen, Lauren M

2014-02-01

Low-income and some racial and ethnic subpopulations are more likely to suffer from obesity. Inequities in the physical and social environment may contribute to disparities in paediatric obesity, but there is little empirical evidence to date. This study explored whether neighbourhood-level socioeconomic factors attenuate racial and ethnic disparities in obesity among youth in the U.S.A. and whether individual-level socioeconomic status (SES) interacts with neighbourhood deprivation. This analysis used data from 17,100 youth ages 2-18 years participating in the 2001-2010 National Health and Nutrition Examination Survey linked to census tract-level socioeconomic characteristics. Multilevel logistic regression models were used to examine neighbourhood deprivation in association with odds of obesity (age-specific and sex-specific body mass index percentile ≥95). The unadjusted prevalence of obesity was 15% among non-Hispanic white children and 21% among non-Hispanic black and Mexican-American children. Adjustment for individual-level SES neighbourhood deprivation and the interaction between these two factors resulted in a 74% attenuation of the disparity in obesity between non-Hispanic black and non-Hispanic white children and a 49% attenuation of the disparity between Mexican-American and non-Hispanic white children. There was a significant interaction between individual-level SES and neighbourhood deprivation where higher individual-level income was protective for children living in low-deprivation neighbourhoods, but not for children who lived in high-deprivation areas. Conversely, area deprivation was associated with higher odds of obesity, but only among children who were above the poverty threshold. Future research on disparities in obesity and other health outcomes should examine broader contextual factors and social determinants of inequities.

To see if obesity, deaths from diabetes, and daily calorie intake are associated with income inequality among developed countries. Ecological study of 21 developed countries.Countries: Countries were eligible for inclusion if they were among the top 50 countries with the highest gross national income per capita by purchasing power parity in 2002, had a population over 3 million, and had available data on income inequality and outcome measures. Percentage of obese (body mass index >30) adult men and women, diabetes mortality rates, and calorie consumption per capita per day. Adjusting for gross national per capita income, income inequality was positively correlated with the percentage of obese men (r = 0.48, p = 0.03), the percentage of obese women (r = 0.62, p = 0.003), diabetes mortality rates per 1 million people (r = 0.46, p = 0.04), and average calories per capita per day (r = 0.50, p = 0.02). Correlations were stronger if analyses were weighted for population size. The effect of income inequality on female obesity was independent of average calorie intake. Obesity, diabetes mortality, and calorie consumption were associated with income inequality in developed countries. Increased nutritional problems may be a consequence of the psychosocial impact of living in a more hierarchical society.

Obesity, particularly abdominal obesity, is currently considered a chronic low-grade inflammatory condition that plays an active role in the development of the pathophysiologic phenomena responsible for metabolic syndrome and cardiovascular disease through the secretion of proinflammatory adipokines and cytokines. In recent years clear genetic, pathogenic, and epidemiologic links have been established between psoriasis and obesity, with important implications for health. The relationship between the 2 conditions is probably bidirectional, with obesity predisposing to psoriasis and psoriasis favoring obesity. Obesity also has important implications in the treatment of psoriasis, such as a greater risk of adverse effects with conventional systemic drugs and reduced efficacy and/or increased cost with biologic agents, for which dosage should be adjusted to the patient's weight.

Obesity and sexual abuse in American Indians and Alaska Natives.

Mainstream American culture frequently minimizes the prevalence and significance of sexual abuse. Unfortunately, this denial of extensive victimization of women is also present in many underserved populations. In June 2007, Amnesty International released its report on sexual abuse in indigenous women, which states that, "One in three Native American or Alaska Native women will be raped at some point in their lives. Most do not seek justice because they know they will be met with inaction or indifference." This report highlighted an infrequently discussed issue namely, very high levels of sexual abuse in Native American and Alaska Native women. The relationship between sexual abuse and obesity has been delineated in several studies; overall about one quarter to one half of women with high levels of obesity have been sexually abused and it has been postulated that weight-gain serves as an adaptive response for many survivors of sexual abuse. It is also well known in Native American and Alaskan Native women that there is a high prevalence of obesity (about 40% greater than the population average) and that this obesity is associated with a many-fold greater risk of diabetes and increased risks of hypertension, cancer and cardiovascular disease. The link between the concomitantly high rates of sexual abuse and obesity in this population may or may not be partial causality but the issue is nonetheless important. If approaches are to succeed in reversing the trend of increasing levels of obesity in Native American and Alaskan Native women, the high prevalence of sexual abuse will need to be specifically and comprehensively addressed.

Obesity and Outcome of Assisted Reproduction in Patients With Polycystic Ovary Syndrome

2018-01-01

Assisted reproduction, including in vitro fertilization and intracytoplasmic sperm injection, is increasingly being used for the management of infertility in patients with polycystic ovary syndrome (PCOS). However, there are limited data regarding the association between obesity and the outcome of assisted reproduction in this specific population as well as on the effects of weight loss. The aim of the present review is to summarize the existing evidence on the association between obesity and the outcome of assisted reproduction in patients with PCOS. Accumulating data suggest that obesity is associated with lower pregnancy and live birth rates in patients with PCOS who are undergoing assisted reproduction therapy. However, it remains unclear whether weight loss improves the outcome of this therapy. Notably, recent guidelines state that the health benefits of postponing pregnancy to achieve weight loss must be balanced against the risk of declining fertility with advancing age. Therefore, if weight loss is not achieved within a reasonable time period, assisted reproduction therapy should be offered in adequately selected patients with PCOS, regardless of the presence of obesity.

First, to study the difference between two groups of postmenopausal women living in different population centres (rural vs urban) in the prevalence of osteoporosis, fragility fractures and factors which may influence them: hypovitaminosis D, bone mineral density, coexistence of other diseases which predispose to their appearance; secondly, to observe the influence of low socioeconomic status, categorised as poverty. 1229 postmenopausal women were studied, of whom 390 (31.7%), were living in rural areas and 839 (68.3%), in urban areas. Data regarding risk factors related to osteoporosis were obtained, and, among other biochemical measures, 25 hydroxyvitamin D and parathyroid hormone were determined. Bone densitometry was carried out in the lumbar spine and proximal femur, as well as lateral X-rays of the dorsal and lumbar spine. The women who lived in rural areas were older, shorter, heavier and had a higher body mass index than those from urban areas. Among the women from rural areas there was a higher prevalence of poverty, and higher levels of obesity, arterial hypertension and diabetes mellitus were observed, as well as a higher prevalence of densitometric osteoporosis. The rural women had lower values of bone mineral density in the lumbar spine and a higher prevalence of vertebral fractures and hypovitaminosis D. The variables which were associated independently with living in rural areas were poverty, obesity, vertebral fractures, BMD in the lumbar spine and levels of 25 hydroxyvitamin D. In our study, postmenopausal women who live in rural populations have more poverty, lower values of vitamin D, lower BMD in the lumbar spine and a higher prevalence of vertebral fractures and of osteoporosis. The higher prevalence of obesity, arterial hypertension and diabetes mellitus observed in these women may be adjuvant factors, all fostered by their socioeconomic state of poverty. Copyright © 2014.

The level of fatness at which morbidity increases is determined on an acturial basis. Direct measurements of body fat content, eg hydrodensitometry, bioimpedance or DEXA, are useful tools in scientific studies. However, body mass index (BMI) is easy to calculate and is frequently used to define obesity clinically. An increased risk of death from cardiovascular disease in adults has been found in subjects whose BMI had been greater than the 75th percentile as adolescents. Childhood obesity seems to increase the risk of subsequent morbidity whether or not obesity persists into adulthood. The genetic basis of childhood obesity has been elucidated to some extent through the discovery of leptin, the ob gene product, and the increasing knowledge on the role of neuropeptides such as POMC, neuropeptide Y (NPY) and the melanocyte concentrating hormone receptors (MC4R). Environmental/exogenous factors contribute to the development of a high degree of body fatness early in life. Twin studies suggest that approximately 50% of the tendency toward obesity is inherited. There are numerous disorders including a number of endocrine disorders (Cushing's syndrome, hypothyroidism, etc) and genetic syndromes (Prader-Labhard-Willi syndrome, Bardet-Biedl syndrome etc) that can present with obesity. A simple diagnostic algorithm allows for the differentiation between primary or secondary obesity. Among the most common sequelae of primary childhood obesity are hypertension, dyslipidemia and psychosocial problems. Therapeutic strategies include psychological and family therapy, lifestyle/behavior modification and nutrition education. The role of regular exercise and exercise programs is emphasized. Surgical procedures and drugs used as treatments for adult obesity are still not recommended for children and adolescents with obesity. As obesity is the most common chronic disorder in the industrialized societies, its impact on individual lives as well as on health economics has to be

To examine the association of total animal protein intake and protein derived from different dietary sources (meat; fish and shellfish; eggs; milk products) with global and abdominal obesity among adults in Luxembourg. Binary logistic regression analysis was used to assess the relationship between animal protein intake (as a percentage of total energy intake) and global obesity (BMI ≥ 30.0 kg/m(2)) and abdominal obesity (waist circumference ≥ 102 cm for men and ≥ 88 cm for women), after controlling for potential confounders. Observation of Cardiovascular Risk Factors in Luxembourg (ORISCAV-LUX) study. The study population was derived from a national cross-sectional stratified sample of 1152 individuals aged 18-69 years, recruited between November 2007 and January 2009. There was an independent positive association between total animal protein intake and both global (OR = 1.18; 95% CI 1.12, 1.25) and abdominal obesity (OR = 1.14; 95% CI 1.08, 1.20) after adjustment for age, gender, education, smoking, physical activity and intakes of total fat, carbohydrate, fibre, and fruit and vegetables. Protein intakes from meat, fish and shellfish were positively associated with global and abdominal obesity with further adjustment for vegetal protein and other sources of animal-derived protein (all P < 0.01). Protein derived from eggs or milk products was unrelated to global or abdominal obesity. Our findings suggest that protein derived from animal sources, in particular from meat, fish and shellfish, may be associated with increased risk of both global and abdominal obesity among presumably healthy adults in Luxembourg. These findings suggest that lower animal protein intakes may be important for maintenance of healthy body weight.

Homozygosity for a novel missense mutation in the leptin receptor gene (P316T) in two Egyptian cousins with severe early onset obesity.

Congenital deficiency of the leptin receptor is a very rare cause of severe early-onset obesity. To date, only 9 families have been reported in the literature to have mutations in the leptin receptor gene. The clinical features include severe early onset obesity, severe hyperphagia, hypogonadotropic hypogonadism, and T cell and neuroendocrine/metabolic dysfunction. Here we report two cousins with severe early onset obesity and recurrent respiratory tract infections. Their serum leptin levels were elevated but they were within the range predicted by the elevated fat mass in both cousins. Direct sequencing of the entire coding sequence of the leptin receptor gene revealed a novel homozygous missense mutation in exon 6, P316T. The mutation was found in the homozygous form in both cousins and in the heterozygote state in their parents. This mutation was not found in 200 chromosomes from 100 unrelated normal weight control subjects of Egyptian origin using PCR-RFLP analysis. In conclusion, finding this new mutation in the LEPR beside our previous mutation in the LEP gene implies that monogenic obesity syndromes may be common in the Egyptian population owing to the high rates of consanguineous marriages. Further screening of more families for mutations in LEP, LEPR, and MC4 might confirm this assumption. Copyright © 2010 Elsevier Inc. All rights reserved.

Matched unrelated donor transplants-State of the art in the 21st century.

Hematopoietic stem cell transplantation (HSCT) is the therapy of choice in many hematological malignant and non-malignant diseases by using human leukocyte antigen (HLA)-matched siblings as stem cell source but only one third of the patients will have HLA-matched siblings. Hence, physicians rely on the availability of matched unrelated donors (URD). The possibility of finding a matched URD is now more than 70% due to continuous expansion of URD registries around the world. The use of URD in adult patients is steadily increasing and in the last 8 years has superseded the numbers of matched sibling donor transplants and has become the most commonly used stem cell source. There is also an increasing trend to use peripheral blood (PB) stem cells rather than bone marrow (BM) stem cells. Outcomes following URD transplants depend mainly upon the indication and urgency of transplant, age and comorbidities of recipients, cytomegalovirus (CMV) matching/mismatching between donor and the recipient, and degree of HLA matching. In some studies outcome of unrelated stem cell transplants in terms of treatment-related mortality (TRM), disease-free survival (DFS), and overall survival (OS) is comparable to sibling donors.

The objective of this study was to (a) to examine whether the association between obesity and physical functioning among older adults is moderated by physical activity (PA) and (b) to test whether this moderating effect varies by gender. Data from adults (aged >60 years) who participated in the National Health and Nutrition Examination Surveys (2005-2010) were analyzed. Using multivariate logistic regression, we estimated the prevalence ratio (PR) of functional limitations and impairment in activities of daily living and instrumental activities of daily living, by body mass index and PA, while adjusting for age, educational level, and a comorbidity index. The sample included 5,304 subjects (mean age = 70.4 years), and 50.5% were female. Overweight and obesity were associated with higher levels of functional limitations when compared with normal weight individuals regardless of the PA status (PR = 1.47, 95% confidence interval [CI] [1.17, 1.85], and PR = 2.71, 95% CI [2.00, 3.67], respectively) even after adjustment for confounders. Overweight and obesity are associated with impairment in functional outcomes irrespective of PA. © The Author(s) 2014.
