    Childhood obesity continues to escalate despite considerable efforts to reverse the current trends. Childhood obesity is a leading public health concern because overweight-obese youth suffer from comorbidities such as type 2 diabetes mellitus, nonalcoholic fatty liver disease, metabolic syndrome, and cardiovascular disease, conditions once considered limited to adults. This increasing prevalence of chronic health conditions in youth closely parallels the dramatic increase in obesity, in particular abdominal adiposity, in youth. Although mounting evidence in adults demonstrates the benefits of regular physical activity as a treatment strategy for abdominal obesity, the independent role of regular physical activity alone (e.g., without calorie restriction) on abdominal obesity, and in particular visceral fat, is largely unclear in youth. There is some evidence to suggest that, independent of sedentary activity levels (e.g., television watching or playing video games), engaging in higher-intensity physical activity is associated with a lower waist circumference and less visceral fat. Several randomized controlled studies have shown that aerobic types of exercise are protective against age-related increases in visceral adiposity in growing children and adolescents. However, evidence regarding the effect of resistance training alone as a strategy for the treatment of abdominal obesity is lacking and warrants further investigation.

    Rapidly rising childhood obesity rates constitute a public health priority in Latin America which makes it imperative to develop evidence-based strategies. Schools are a promising setting but to date it is unclear how many school-based obesity interventions have been documented in Latin America and what level of evidence can be gathered from such interventions. We performed a systematic review of papers published between 1965 and December 2010. Interventions were considered eligible if they had a school-based component, were done in Latin America, evaluated an obesity related outcome (body mass index [BMI], weight, %body fat, waist circumference, BMI z-score), and compared youth exposed vs not exposed. Ten studies were identified as having a school-based component. Most interventions had a sample of normal and overweight children. The most successful interventions focused on prevention rather than treatment, had longer follow-ups, a multidisciplinary team, and fewer limitations in execution. Three prevention and 2 treatment interventions found sufficient improvements in obesity-related outcomes. We found sufficient evidence to recommend school-based interventions to prevent obesity among youth in Latin America. Evidence-based interventions in the school setting should be promoted as an important component for integrated programs, policies, and monitoring frameworks designed to reverse the childhood obesity in the region.

    Youth advocacy has been successfully used in substance use prevention but is a novel strategy in obesity prevention. As a precondition for building an evidence base for youth advocacy for obesity prevention, the present study aimed to develop and evaluate measures of youth advocacy mediator, process, and outcome variables. The Youth Engagement and Action for Health (YEAH!) program (San Diego County, CA) engaged youth and adult group leaders in advocacy for school and neighborhood improvements to nutrition and physical activity environments. Based on a model of youth advocacy, scales were developed to assess mediators, intervention processes, and proximal outcomes of youth advocacy for obesity prevention. Youth (baseline n = 136) and adult group leaders (baseline n = 47) completed surveys before and after advocacy projects. With baseline data, we created youth advocacy and adult leadership subscales using confirmatory factor analysis (CFA) and described their psychometric properties. Youth came from 21 groups, were ages 9-22, and most were female. Most youth were non-White, and the largest ethnic group was Hispanic/Latino (35.6%). The proposed factor structure held for most (14/20 youth and 1/2 adult) subscales. Modifications were necessary for 6 of the originally proposed 20 youth and 1 of the 2 adult multi-item subscales, which involved splitting larger subscales into two components and dropping low-performing items. Internally consistent scales to assess mediators, intervention processes, and proximal outcomes of youth advocacy for obesity prevention were developed. The resulting scales can be used in future studies to evaluate youth advocacy programs.

  4. Obesity, Overweightness, and Depressive Symptomology Among American Indian Youth.

    Despite evidence that American Indian adolescents are at a heightened risk of obesity/overweightness and experiencing depression, relative to other groups, there exists a dearth of studies that have examined the association between objective and perceptual measures of obesity and overweightness and depression with this understudied group. Our study represents one of the first studies to examine this association among American Indian youth. Using a subsample of American Indian youth from waves I and II of the National Longitudinal Study of Adolescent Health (a survey of schools and students in the USA, with wave I collected in 1994 and wave II collected in 1995), we explore this association. We examine three measures of weight: obesity, body mass index, and weight perception. We also consider gender-specific models and a subsample of non-Hispanic whites, in order to assess race differences in the obesity and overweightness-depression relationship. Our findings reveal that neither of our objective measures of weight, obesity, nor body mass index are significant predictors of depressive symptoms for either American Indian or white youth. However, we find evidence that the subjective measure of weight perception is a significant predictor of depressive symptoms for white females, but not for American Indian females. Our results contribute to past findings that measures of obesity/overweightness weight may be more important to white female's mental health than females from other racial groups, although additional research is warranted.

    Introduction. Given the high prevalence of childhood obesity in the United States, we aimed to investigate youth's understanding of obesity and to investigate gaps between their nutritional knowledge, dietary habits, and perceived susceptibility to obesity and its co-morbidities. Methods. A marketing firm contracted by Children's Healthcare of Atlanta facilitated a series of focus group discussions (FGD) to test potential concepts and sample ads for the development of an obesity awareness campaign. Data were collected in August and September of 2010 with both overweight and healthy weight 4th-5th grade and 7th-8th grade students. We conducted a secondary analysis of the qualitative FGD transcripts using inductive thematic coding to identify key themes related to youth reports of family eating habits (including food preparation, meal frequency, and eating environment), perceived facilitators and barriers of healthy diet, and knowledge about obesity and its complications. Results. Across focus group discussions, mixed attitudes about healthy eating, low perceived risk of being or becoming obese, and limited knowledge about the health consequences of obesity may contribute to the rising prevalence of obesity among youth in Georgia. Most youth were aware that obesity was a problem; yet most overweight youth felt that their weight was healthy and attributed overweight to genetics or slow metabolism. Conclusions. Our analysis suggests that urban youth in Georgia commonly recognize obesity as a problem, but there is less understanding of the link to lifestyle choices or the connection to future morbidities, suggesting a need for education to connect lifestyle behaviors to development of obesity.

    Weight status on children and youth with autism spectrum disorder is limited. We examined the prevalence of overweight/obesity in children and youth with autism spectrum disorder, and associations between weight status and range of factors. Children and youth with autism spectrum disorder aged 2-16 years (n = 208) and their parents participated in this study. Body mass index was calculated using the Centers for Disease Control and Prevention growth charts and the International Obesity Task Force body mass index cut-offs. The Autism Diagnostic Observation Schedule was administered. Parents completed questionnaires about socio-demographics, diagnosed comorbidities, sleep disturbances, social functioning and medication of youth with autism spectrum disorder. The prevalence of overweight/obesity in participants with autism spectrum disorder was 35%. One quarter of obese children and youth (25.6%) had obese parents. There was a significant association between children and youth's body mass index and maternal body mass index (r = 0.25, n = 199, p < 0.001). The gender and age, parental education, family income, ethnicity, autism spectrum disorder severity, social functioning, psychotropic and complementary medication use of children and youth with autism spectrum disorder were not statistically associated with their weight status. Findings suggest the need for clinical settings to monitor weight status of children and youth with autism spectrum disorder in a bid to manage or prevent overweight/obesity in this population. Incorporating a family system approach to influence health behaviours among children and youth with autism spectrum disorder especially for specific weight interventions is warranted and should be further explored. © The Author(s) 2016.

    This study explores differences in weight status, obesity and patterns of physical activity (PA) in relation to gender and age of youth from two culturally, environmentally and geographically diverse countries, the United Kingdom (UK) and Saudi Arabia (SA). A total of 2,290 males and females (15–17 years) volunteered to participate in this study. Participants completed a validated self-report questionnaire that contained 47 items relating to patterns of PA, sedentary activity and eating habits. The questionnaire allows the calculation of total energy expenditure in metabolic equivalent (MET-min) values per week. Significant differences in percentage of overweight/obese and levels of PA were evident between the youth from the two countries, with males being generally more physically active than females. Additionally, there were significant associations between Body Mass Index (BMI), PA and sedentary behaviors; the youth with higher BMI reported lower levels of PA and higher amounts of sedentary time. These findings highlight the diverse nature of lifestyle of youth living in different geographical areas of the world and the need for further research to explore the socio-cultural factors that impact on the prevalence of obesity and patterns of PA of youth in different populations.

    School nurses are well aware of the childhood obesity epidemic in the United States, as one in three youth are overweight or obese. Co-morbidities found in overweight or obese adults were not commonly found in youth three decades ago but are now increasingly "normal" as the obesity epidemic continues to evolve. This article is the second of six related articles discussing the co-morbidities of childhood obesity and discusses the complex association between obesity and insulin resistance, metabolic syndrome, and polycystic ovary syndrome. Insulin resistance increases up to 50% during puberty, which may help to explain why youth are more likely to develop co-morbidities as teens. Treatment of these disorders is focused on changing lifestyle habits, as a child cannot change his or her pubertal progression, ethnicity, or family history. School nurses and other personnel can assist youth with insulin resistance, metabolic syndrome, and polycystic ovary syndrome by supporting their efforts to make changes, reinforcing that insulin resistance is not necessarily type 2 diabetes even if the child is taking medication, and intervening with negative peer pressure. © 2015 The Author(s).

    Obesity among the Mexican-origin adult population in the US has been associated with longer stays in the US and with being US- vs. Mexican-born, two proxies for acculturation. This pattern is less clear for Mexican-origin children and young adults: recent evidence suggests that it may be reversed, with foreign-born Mexican youth in the US at higher risk of obesity than their US-born Mexican–American counterparts. The objective of this study is to evaluate the hypothesis that the immigrant advantage in obesity prevalence for Mexican-origin populations in the US does not hold for children and young adults. We use data from the Los Angeles Family and Neighborhood Survey (N = 1143) and the California Health Interview Survey (N = 25,487) for respondents ages 4–24 to calculate the odds of overweight/obesity by ethnicity and nativity. We find support for the hypothesis that overweight/obesity prevalence is not significantly lower for first-generation compared to second- and third-generation Mexican-origin youth. Significantly higher obesity prevalence among the first generation was observed for young adult males (ages 18–24) and adolescent females (ages 12–17). The previously-observed protective effect against obesity risk among recent adult immigrants does not hold for Mexican-origin youth. PMID:23273875

    To assess the interaction of parent and child characteristics with feeding practices and mealtime functioning. Longitudinal, predictive study comparing baseline characteristics with follow-up assessments. The caregivers of 52 persistently obese youth and 32 nonoverweight comparison youth completed measurements of child temperament, parental feeding practices, parenting styles, and interactions during mealtimes. Adolescents with persistent obesity were significantly more likely to be parented using problematic feeding practices when parents also reported difficult child temperaments. Additionally, adolescents with persistent obesity and difficult temperaments were significantly more likely to have lower levels of positive mealtime interactions. Persistently obese youth are at increased risk for problematic parental feeding practices and mealtime functioning, particularly when youth are described as having difficult temperaments. These results indicate that further investigations are needed to better understand the mechanisms linking parent and child characteristics with health-related behaviors for adolescents with obesity.

    Despite careful planning and implementation, overweight/obesity prevention interventions in children and adolescents typically show no, inconsistent or merely weak effects. Such programs usually aim at behavior changes, rarely also at environmental changes, that draw upon conventional wisdom regarding the commonly accepted determinants of childhood overweight/obesity. This paper evaluates the evidence base of the apparently overweight-/obesity-related determinants diet, physical activity and stress. The results of international intervention studies are discussed against this background. Based on the mediating-moderating variable model, we investigate the effect of theory specified mediating variables and how potential moderating variables may impact these relationships. Contrary to common beliefs, recent research has revealed inconsistent evidence regarding associations between potentially obesogenic behaviors and overweight/obesity in youth. Moreover, the evidence for strong and causal relationships between mediating variables and targeted behaviors seems to be inconsistent. In addition, inadequate attention is paid to moderating effects. The etiology of overweight/obesity in youth is likely the result of a complex interplay of multi-causal influences. Future prevention interventions would benefit from a more thorough understanding of the complex relationships that have been hypothesized and of the mechanisms of suspected behaviors for affecting overweight/obesity. Only if substantial change can be demonstrated in mediators with reasonable effort under real world circumstances, it will make sense to progress to community behavior change trials.

    Nurturing environments within the context of families, schools, and communities all play an important role in enhancing youth's behavioral choices and health outcomes. The increasing prevalence rates of obesity among youth, especially among low income and ethnic minorities, highlight the need to develop effective and innovative intervention approaches that promote positive supportive environments across different contexts for at-risk youth. We propose that the integration of Social Cognitive Theory, Family Systems Theory, and Self-Determination Theory offers a useful framework for understanding how individual, family, and social-environmental-level factors contribute to the development of nurturing environments. In this paper, we summarize evidence-based randomized controlled trials that integrate positive parenting, motivational, and behavioral skills strategies in different contexts, including primary care, home, community, and school-based settings. Taken together, these studies suggest that youth and parents are most likely to benefit when youth receive individual-level behavioral skills, family-level support and communication, and autonomous motivational support from the broader social environment. Future investigators and healthcare providers should consider integrating these evidence-based approaches that support the effects of positive social climate-based interventions on promoting healthy eating, physical activity, and weight management in youth.

    A growing number of childhood obesity interventions involve children and youth in participatory roles, but these types of interventions have not been systematically reviewed. We aimed to identify child and youth participatory interventions in the peer-reviewed literature in order to characterize the approaches and examine their impact on obesity and obesity-related lifestyle behaviours. We searched PubMed/Medline, psychINFO and ERIC for quasi-experimental and randomized trials conducted from date of database initiation through May 2015 that engaged children or youth in implementing healthy eating, physical activity or weight management strategies. Eighteen studies met our eligibility criteria. Most (n = 14) trained youth to implement pre-defined strategies targeting their peers. A few (n = 4) assisted youth to plan and implement interventions that addressed environmental changes. Thirteen studies reported at least one statistically significant weight, physical activity or dietary change outcome. Participatory approaches have potential, but variation in strategies and outcomes leave questions unanswered about the mechanisms through which child and youth engagement impact childhood obesity. Future research should compare child-delivered or youth-delivered to adult-delivered health promotion interventions and more rigorously evaluate natural experiments that engage youth to implement environmental changes. With careful attention to theoretical frameworks, process and outcome measures, these studies could strengthen the effectiveness of child and youth participatory approaches. © 2016 World Obesity Federation.

    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.

    Sport is a promising setting for obesity prevention among youth, but little is known about whether it prevents obesity. We reviewed research comparing sport participants with nonparticipants on weight status, physical activity, and diet. Among 19 studies, we found no clear pattern of association between body weight and sport participation. Among 17 studies, we found that sport participants are more physically active than those who do not participate. We found seven studies that compared the diet of sport participants with non-participants. These studies reported that youth involved in sport were more likely to consume fruits, vegetables, and milk, and also more likely to eat fast food and drink sugar-sweetened beverages and consume more calories overall. It is unclear from these results whether sports programs, as currently offered, protect youth from becoming overweight or obese. Additional research may foster understanding about how sport, and youth sport settings, can help promote energy balance and healthy body weight.

    Obesity and overweight prevalence in African American (AA) youth continues to be one of the highest of all major ethnic groups, which has led researchers to pursue culturally based approaches as a means to improve obesity prevention interventions. The purpose of this systematic review was to evaluate culturally adapted obesity prevention interventions targeting AA youth. A search of electronic databases, limited to multicomponent culturally adapted obesity prevention controlled trials from 2003 to 2013, was conducted for key terms. Eleven studies met inclusion criteria. We used the PEN-3 model to evaluate the strengths and weaknesses of interventions as well as to identify cultural adaptation strategies. The PEN-3 model highlighted the value of designing joint parent-youth interventions, building a relationship between AA mentors and youth, and emphasizing healthful activities that the youth preferred. The PEN-3 model shows promise as an overarching framework to develop culturally adapted obesity interventions. © The Author(s) 2015.

    To examine maternal parenting behaviors, child temperament and their potential interactions in families of obese children and demographically similar families of nonoverweight children. A total of 77 obese youth (M body mass index (BMI) z-score values, zBMI=2.4; ages 8-16, 59% female, 50% African American) and their parents were recruited from a pediatric weight management clinic and compared to 69 families of nonoverweight youth (M zBMI=-0.03). Comparison youth were classmates of each obese participant matched on gender, race and age. Maternal report of child temperament, parenting style and anthropometric assessments were obtained. Compared to nonoverweight youth, mothers of obese youth described their child as having a more difficult temperament and their parenting style as lower in behavioral control. A logistic regression model indicated that difficult temperament, lower behavioral control and the interaction of low maternal warmth and difficult child temperament were associated with increased odds of a child being classified as obese. Treatment-seeking obese youth and their parents are characterized by different parent and child factors when compared to nonoverweight comparison families. These findings direct investigators to test more complex models of the relation between parent and child characteristics and their mutual role in the weight-related behavior change process.

    The current study examined self-worth and body size dissatisfaction, and their association with maternal acculturation among obese Latino youth enrolled in a community-based obesity intervention program. Upon entry to the program, a sample of 113 participants reported global self-worth comparable to general population norms, but lower athletic competence and perception of physical appearance. Interestingly, body size dissatisfaction was more prevalent among younger respondents. Youth body size dissatisfaction was associated with less acculturated mothers and higher maternal dissatisfaction with their child's body size. By contrast, although global self-worth was significantly related to body dissatisfaction, it was not influenced by mothers’ acculturation or dissatisfaction with their own or their child’s body size. Obesity intervention programs targeted to Latino youth need to address self-worth concerns among the youth as well as addressing maternal dissatisfaction with their children’s body size.

    Though bivariate relationships between childhood obesity, physical activity, friendships and television viewing are well documented, empirical assessment of the extent to which links between obesity and television may be mediated by these factors is scarce. This study examines the possibility that time with friends and physical activity are potential mechanisms linking overweight/obesity to television viewing in youth. Data were drawn from children ages 10-18 years old (M = 13.81, SD = 2.55) participating in the 2002 wave of Child Development Supplement (CDS) to the Panel Study of Income Dynamics (PSID) (n = 1,545). Data were collected both directly and via self-report from children and their parents. Path analysis was employed to examine a model whereby the relationships between youth overweight/obesity and television viewing were mediated by time spent with friends and moderate-to-vigorous physical activity (MVPA). Overweight/obesity was directly related to less time spent with friends, but not to MVPA. Time spent with friends was directly and positively related to MVPA, and directly and negatively related to time spent watching television without friends. In turn, MVPA was directly and negatively related to watching television without friends. There were significant indirect effects of both overweight/obesity and time with friends on television viewing through MVPA, and of overweight/obesity on MVPA through time with friends. Net of any indirect effects, the direct effect of overweight/obesity on television viewing remained. The final model fit the data extremely well (χ2 = 5.77, df = 5, p<0.0001, RMSEA = 0.01, CFI = 0.99, TLI =0.99).

Height and weight were measured; body mass index (BMI) was calculated. Overweight and obesity were defined by international (International Obesity Task Force [IOTF]) and United States (Centers for Disease Control [CDC]) criteria. Prevalence and 95% confidence interval were calculated. Player age, height, and weight and midparent height were used to predict mature height; current height was expressed as a percentage of predicted mature height as an estimate of maturity status. Overall 45.0% (41.2% to 48.9%) and 42.6% (38.8% to 46.5%) of players were overweight or obese by CDC and IOTF criteria, respectively. Prevalence was highest in early maturing boys. Based on position-activity at time of injury (n = 180), overweight and obesity were more common among offensive and defensive linemen. Overweight and obesity were more prevalent in youth football players than in national samples of American boys. Allowing for limitations of the BMI and the relative stability of the BMI from adolescence into adulthood, a relatively large number of football participants may be at risk for later overweight or obesity, and the risk appears to be greater for offensive and defensive line positions.

    Nurturing environments within the context of families, schools, and communities all play an important role in enhancing youth’s behavioral choices and health outcomes. The increasing prevalence rates of obesity among youth, especially among low income and ethnic minorities, highlight the need to develop effective and innovative intervention approaches that promote positive supportive environments across different contexts for at risk youth. We propose that the integration of Social Cognitive Theory, Family Systems Theory, and Self-Determination Theory offers a useful framework for understanding how individual, family and social-environmental level factors contribute to the development of nurturing environments. In this paper, we summarize evidence-based randomized controlled trials that integrate positive parenting, motivational, and behavioral skills strategies in different contexts, including primary care, home, community, and school-based settings. Taken together, these studies suggest that youth and parents are most likely to benefit when youth receive individual-level behavioral skills, family-level support and communication, and autonomous motivational support from the broader social environment. Future investigators and health care providers should consider integrating these evidence-based approaches that support the effects of positive social climate-based interventions on promoting healthy eating, physical activity, and weight management in youth.

    Objective To examine maternal parenting behaviors, child temperament and their potential interactions in families of obese children and demographically similar families of nonoverweight children. Design A total of 77 obese youth (M body mass index (BMI) z-score values, zBMI = 2.4; ages 8–16, 59% female, 50% African American) and their parents were recruited from a pediatric weight management clinic and compared to 69 families of nonoverweight youth (M zBMI = − 0.03). Comparison youth were classmates of each obese participant matched on gender, race and age. Measurements Maternal report of child temperament, parenting style and anthropometric assessments were obtained. Results Compared to nonoverweight youth, mothers of obese youth described their child as having a more difficult temperament and their parenting style as lower in behavioral control. A logistic regression model indicated that difficult temperament, lower behavioral control and the interaction of low maternal warmth and difficult child temperament were associated with increased odds of a child being classified as obese. Conclusions Treatment-seeking obese youth and their parents are characterized by different parent and child factors when compared to nonoverweight comparison families. These findings direct investigators to test more complex models of the relation between parent and child characteristics and their mutual role in the weight-related behavior change process.

    Sport is a promising setting for obesity prevention among youth, but little is known about whether it prevents obesity. We reviewed research comparing sport participants with non-participants on weight status, physical activity and diet. Among nineteen studies we found no clear pattern of association between body weight and sport participation. Among seventeen studies we found that sport participants are more physically active than those who do not participate. Seven studies examined the relationship between sport participation and diet and found that sport participation is associated with more fruit, vegetable and milk consumption, but also more fast food and sugar sweetened beverage consumption and greater overall calorie intake. It is unclear from these results whether sports programs, as currently offered, protect youth from becoming overweight or obese. Additional research may foster understanding about how sport, and youth sport settings, can help promote energy balance and healthy body weight. PMID:22071397

    2014-09-01

    The aim of this study was to determine the type and the number of accelerometer monitoring days needed to predict weekly sedentary behaviour and physical activity in obese youth. Fifty-three obese youth wore a triaxial accelerometer for 7 days to measure physical activity in free-living conditions. Analyses of variance for repeated measures, Intraclass coefficient (ICC) and regression linear analyses were used. Obese youth spent significantly less time in physical activity on weekends or free days compared with school days. ICC analyses indicated a minimum of 2 days is needed to estimate physical activity behaviour. ICC were 0·80 between weekly physical activity and weekdays and 0·92 between physical activity and weekend days. The model has to include a weekday and a weekend day. Using any combination of one weekday and one weekend day, the percentage of variance explained is >90%. Results indicate that 2 days of monitoring are needed to estimate the weekly physical activity behaviour in obese youth with an accelerometer. Our results also showed the importance of taking into consideration school day versus free day and weekday versus weekend day in assessing physical activity in obese youth. © 2013 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

    Youth sport participation plays an important role in promoting physical activity among children and may be a possible venue for the prevention of pediatric obesity. To design effective physical activity interventions, it is imperative to understand how different aspects of sport participation influence physical activity (PA). The purpose of this article is to present a comprehensive review of the impact of youth sport participation on children's PA and obesity status. A total of 44 studies published up to January 2014 concerning youth sport participation, PA, and obesity status were identified. Inclusion criteria were studies comparing PA levels of sport participants to nonparticipants or those comparing PA levels in different sport types and settings. Studies with the outcome variables of obesity status (e.g., body mass index, fat percentage, waist circumference) were also included. Participation in youth sport was positively associated with children's PA levels, and youth participating in sports were more likely to persist in their PA. However, the relationship between youth sport participation and obesity status was inconclusive. Educators and sports professionals should find ways to involve children in various sports settings and policies and help obese children engage more in sports.

    Youth with high BMI who become nonobese adults have the same cardiovascular risk factor burden as those who were never obese. However, the early-life BMI trajectories for overweight or obese youth who avoid becoming obese adults have not been described. We aimed to determine and compare the young-childhood BMI trajectories of participants according to their BMI status in youth and adulthood. Bayesian hierarchical piecewise regression modeling was used to analyze the BMI trajectories of 2717 young adults who had up to 8 measures of BMI from childhood (ages 3-18 years) to adulthood (ages 34-49 years). Compared with those with persistently high BMI, those who resolved their high youth BMI by adulthood had lower average BMI at age 6 years and slower rates of BMI change from young childhood. In addition, their BMI levels started to plateau at 16 years old for females and 21 years old for males, whereas the BMI of those whose high BMI persisted did not stabilize until 25 years old for male subjects and 27 years for female subjects. Compared with those youth who were not overweight or obese and who remained nonobese in adulthood, those who developed obesity had a higher BMI rate of change from 6 years old, and their BMI continued to increase linearly until age 30 years. Efforts to alter BMI trajectories for adult obesity should ideally commence before age 6 years. The natural resolution of high BMI starts in adolescence for males and early adulthood for females, suggesting a critical window for secondary prevention.

    Background Advertisement of fast food on TV may contribute to youth obesity. Purpose The goal of the study was to use cued recall to determine whether TV fast-food advertising is associated with youth obesity. Methods A national sample of 2541 U.S. youth, aged 15–23 years, were surveyed in 2010–2011; data were analyzed in 2012. Respondents viewed a random subset of 20 advertisement frames (with brand names removed) selected from national TV fast-food restaurant advertisements (n=535) aired in the previous year. Respondents were asked if they had seen the advertisement, if they liked it, and if they could name the brand. A TV fast-food advertising receptivity score (a measure of exposure and response) was assigned; a 1-point increase was equivalent to affirmative responses to all three queries for two separate advertisements. Adjusted odds of obesity (based on self-reported height and weight), given higher TV fast-food advertising receptivity, are reported. Results The prevalence of overweight and obesity, weighted to the U.S. population, was 20% and 16%, respectively. Obesity, sugar-sweetened beverage consumption, fast-food restaurant visit frequency, weekday TV time, and TV alcohol advertising receptivity were associated with higher TV fast-food advertising receptivity (median=3.3 [interquartile range: 2.2–4.2]). Only household income, TV time, and TV fast-food advertising receptivity retained multivariate associations with obesity. For every 1-point increase in TV fast-food advertising receptivity score, the odds of obesity increased by 19% (OR=1.19, 95% CI=1.01, 1.40). There was no association between receptivity to televised alcohol advertisements or fast-food restaurant visit frequency and obesity. Conclusions Using a cued-recall assessment, TV fast-food advertising receptivity was found to be associated with youth obesity. PMID:24139768

    Island Puerto Rican (PR) youth experience disproportionately high asthma and obesity rates compared with other racial/ethnic groups on the U.S. mainland. Previous research has demonstrated associations of chronic disease with psychiatric disorders. We examined the relationship among anxiety/depressive disorders, asthma, and obesity in an epidemiologic community sample of youth. The sample (n = 656) was derived from the second wave of an island-wide probabilistic representative household sample of PR youth stratified and based on whether or not they had a diagnosis of asthma and/or depressive/anxiety disorder. For this study, we used the subpopulation ages 10-19 years. Asthma and obesity were significantly related to higher odds of depressive/anxiety disorders in youth. Obesity moderated the relationship between asthma attacks and depressive/anxiety disorders. The relationship between asthma attack and higher odds for depressive/anxiety disorders was only present in the non-obese group. Among the obese, females show a significant increase from 11% to 36% in the prevalence of anxiety/depressive disorders. Asthma and obesity were highly prevalent and a significant association was found between asthma attack and depressive/anxiety disorders. The effects of asthma and obesity were not additive; the prevalence for psychiatric disorder for those having both conditions did not increase above the prevalence associated having only one of the conditions. Future studies should consider including longitudinal designs and examine the extent to which important variables not included in this study, such as body image dissatisfaction (particularly among females), teasing, and discrimination may moderate the relationship among obesity and depressive and anxiety disorders in youth.

    Overweight and obesity have become major public health concerns in the United States, reaching epidemic proportions among adults and children in recent years. According to the most recent national surveys, American adults have experienced a 50% increase in the prevalence of overweight and obesity. Moreover, an alarming 100% increase has been observed among children and adolescents since the 1970s. To assess the status of overweight and obesity prevalence among youth in the Carolinas, weight, height, waist, and hip circumferences were monitored during routine cholesterol screenings among 11- to 14-year-olds in two school districts. Of the twelve hundred students screened, 32.4% percent were overweight and 16.4% were obese, exceeding national averages of 22% and 11%, respectively. The overweight and obesity prevalence rates were even more dramatic when broken down by gender and ethnic/racial groups. For instance, 54% of black girls and 45% of black boys were overweight, and better than half of these students were obese. Overweight and obesity prevalence rates among black girls were nearly twice the rates observed for white girls. Ethnic differences in percentage of overweight and obese boys were not as great as those observed among girls. A number of factors may contribute to the unprecedented levels of overweight and obesity observed among American youth, including physical inactivity, poor nutritional habits (i.e., high-fat meals and snacks, and super-sizing), economic, and social factors. Consequently, the coordinated efforts of physicians, school nurses, teachers, parents, and students will be necessary to effectively address the growing problem of childhood obesity.

    Obese youth clinically diagnosed with type 2 diabetes mellitus (T2DM) frequently have evidence of islet cell autoimmunity. We investigated the clinical and biochemical differences, and therapeutic modalities among autoantibody positive (Ab+) vs. autoantibody negative (Ab-) youth at the time of diagnosis and over time in a multi-provider clinical setting. Chart review of 145 obese youth diagnosed with T2DM from January 2003 to July 2012. Of these, 70 patients were Ab+ and 75 Ab-. The two groups were compared with respect to clinical presentation, physical characteristics, laboratory data, and therapeutic modalities at diagnosis and during follow up to assess the changes in these parameters associated with disease progression. At presentation, Ab+ youth with a clinical diagnosis of T2DM were younger, had higher rates of ketosis, higher hemoglobin A1c (HbA1c) and glucose levels, and lower insulin and c-peptide concentrations compared with the Ab- group. The Ab- group had a higher body mass index (BMI) z-score and cardiometabolic risk factors at diagnosis and such difference remained over time. Univariate analysis revealed that treatment modality had no effect on BMI in either group. Generalized estimating equations for longitudinal data analysis revealed that (i) BMI z-score and diastolic blood pressure (DBP) were significantly affected by duration of diabetes; (ii) systolic blood pressure (SBP) and ALT were affected by changes in BMI z-score; and (iii) changes in HbA1c had an effect on lipid profile and cardiometabolic risk factors regardless of antibody status. Irrespective of antibody status and treatment modality, youth who present with obesity and diabetes, show no improvement in obesity status over time, with the deterioration in BMI z-score affecting blood pressure (BP) and ALT, but the lipid profile being mostly impacted by HbA1c and glycemic control. Effective control of BMI and glycemia are needed to lessen the future macrovascular complications irrespective

    Most studies on the role of family environment in developing risk of obesity among youth have focused on parenting behaviors that are directly involved in energy balance in regional, non-representative White samples. Using a national sample of ethnically diverse Black youth, the current study tested the association between low family support and risk of obesity. We also tested the heterogeneity of this association based on gender, ethnicity, and their intersection. We used data from the National Survey of American Life-Adolescent Supplement (NSAL-A), a national survey of Black adolescents in the United States. The study enrolled 1170 African American and Caribbean Black 13–17 year old youth. Obesity was defined based on the cutoff points of body mass index (BMI) appropriate for age and gender of youth. Family support was measured using a five-item measure that captured emotional and tangible social support. Age, gender, and ethnicity were also measured. Logistic regressions were utilized in the pooled sample, and also based on gender, ethnicity, and their intersection, to test the link between low family support and risk for obesity. Results: In the pooled sample, low family support was not associated with an increased risk of obesity (OR = 1.35, 95% Confidence Interval (CI) = 0.96–1.89). The association between low family support and risk of obesity was, however, significant among African American females (OR = 1.60, 95% CI = 1.01–2.55). There was no association for African American males (OR = 1.26, 95% CI = 0.82–1.92), Caribbean Black males (OR = 0.68, 95% CI = 0.01–54.85), and Caribbean Black females (OR = 0.78, 95% CI = 0.42–1.44). In conclusion, policies and programs that enable African American families to provide additional family support may prevent obesity among African American female youth. Future research should test the efficacy of promoting family support as a tool for preventing obesity among African American female youth. PMID:28498351

    Variation in the existing literature on the psychosocial benefits of weight loss in obese youth results, in part, from methodological limitations and modest weight loss. Accordingly, this research assessed perceived self-competence and low self-esteem during an intensive weight loss programme in a large sample of obese youth and related these to starting weight, gender and weight loss. Over 4 years, 303 obese male and female adolescents (body mass index [BMI] 34.3 kg m -2 , BMI standard deviation score 2.99; 14.7 years) attended a residential weight loss camp for a mean duration of 31 d. Outcome variables included dimensional self-esteem (Harter) and weight change over the camp. At the start of camp, obese youth scored highest on social acceptance and lowest on physical appearance and athletic competence. Global self-worth and most domains of self-competence improved significantly over the intervention. The proportion with low global self-worth reduced from 35% to 16%, but there was little change in the proportion reporting high self-competence (23%). Mean weight loss was -5.5 kg (BMI standard deviation scores -0.25) with boys and those heaviest at the start losing most. Weight loss was significantly correlated with improved physical appearance (r = 0.13) and athletic competence (r = 0.19), but not global self-worth. This intensive weight loss intervention yielded significant psychological benefit, especially in self-competence and among individuals achieving most weight loss. The weak association with weight loss suggests the influence of other contributing environmental or social features that should be the focus of further research. © 2016 World Obesity Federation.

    Little is known about the suitability of three commonly used body mass index (BMI) classification systems for Indigenous youth. We estimated overweight and obesity prevalence among Cree youth of Eeyou Istchee according to three BMI classification systems, assessed the level of agreement between them, and evaluated their accuracy through body fat and cardiometabolic risk factors. Data on 288 youth (aged 8-17 years) were collected. Overweight and obesity prevalence were estimated with Centers for Disease Control and Prevention (CDC), International Obesity Task Force (IOTF) and World Health Organization (WHO) criteria. Agreement was measured with weighted kappa (κw). Associations with body fat and cardiometabolic risk factors were evaluated by analysis of variance. Obesity prevalence was 42.7% with IOTF, 47.2% with CDC, and 49.3% with WHO criteria. Agreement was almost perfect between IOTF and CDC (κw = 0.93), IOTF and WHO (κw = 0.91), and WHO and CDC (κw = 0.94). Means of body fat and cardiometabolic risk factors were significantly higher (P trend  < 0.001) from normal weight to obesity, regardless of the system used. Youth considered overweight by IOTF but obese by CDC or WHO exhibited less severe clinical obesity. IOTF seems to be more accurate in identifying obesity in Cree youth.

Heights and weights were measured in cross-sectional samples of school children 6-14 years in the 1970s (2 897) and 2007 (4 305); BMI was calculated. International Obesity Task Force cutoffs for weight status were used. BMI and prevalence of severe and moderate thinness, overweight and obesity were compared by year. BMI increased significantly across time. Primary change in weight status occurred in overweight, 1970s, <2%; 2007, 7 to 12%. Little change occurred in thinness (<2%) and obesity (≤ 1%) in both surveys, except in children 6-9 years (obesity=4% in 2007). BMI and prevalence of overweight increased across all ages from the 1970s to 2007, but children 6-9 years appeared to be more at risk for obesity than youth 10-14 years. Prevalence of thinness was unchanged.

    Childhood obesity rates in minority populations continue to rise despite leveling national trends. Although interventions that address social and environmental factors exist, processes that create demand for policy and environmental change within communities have not been identified. We developed a pilot program in South Omaha, a Nebraska Latino community, based on the community readiness model (CRM), called SaludableOmaha. We used CRM to explore the potential of youth advocacy to shift individual and community norms regarding obesity prevention in South Omaha and to advocate for health-promoting community environments. We used CRM to assess supply and demand for health programs, engage the community, determine the community's baseline readiness to address childhood obesity, and guide youth advocacy program development. We conducted our project in 2 phases. In the first, we trained a cohort of youth. In the second, the youth cohort created and launched a Latino health movement, branded as SaludableOmaha. A third phase, which is currently under way, is directed at institutionalizing youth advocacy in communities. At baseline, the community studied was at a low stage of readiness for change. Our program generated infrastructure and materials to support the growth and institutionalization of youth advocacy as a means of increasing community readiness for addressing obesity prevention. CRM is an important tool for addressing issues such as childhood obesity in underserved communities because it provides a framework for matching interventions to the community. Community partnerships such as SaludableOmaha can aid the adoption of obesity prevention programs.

    Background The prevalence of obesity among youths has become a public health problem. The trend in the prevalence of obesity among high school students in Mississippi has not been examined in the last 17 years. Methods The data from the Mississippi High School Youth Risk Behavior Survey from 1999 to 2015 were used to determine the prevalence of obesity. The definition of obesity was based on age- and sex-specific body mass index (BMI) of more than 95th percentile, according to 2000 Centers for Disease Control and Prevention (CDC) growth charts. The differences in the groups were examined using the univariate t-test statistical analysis at p < 0.05 and frequency distribution to determine the percentage differences. Results There was a decline in the prevalence of obesity from 1999 to 2015 among Whites but no significant decrease among Blacks. The prevalence based on race in 2105 was 18.9%, which is higher than 14.4% in 1999 and remaining years. The rate of obesity based on race and sex was 27.7% among Blacks and 15.9% among White males in 2015. The Black females had prevalence of 20.6%, which is higher than their White counterpart (12.1%) in 2015 and previous years. Conclusion The prevalence of obesity among Blacks was higher when compared to White students. There was an increased prevalence of obesity in males over females. Students in 9th and 10th grade had a higher prevalence of obesity than those in 11th and 12th grade.

    Research suggests that overweight and obese youths are stigmatized in contemporary society, and are more likely than normal-weight youths to become the victims of bullying. In the current study, meta-analyses were performed to analyze to what extent overweight and obese youths are more likely than normal-weight youths to be the victims of bullying. The databases Psychinfo, ERIC and Medline were searched for relevant articles. Retrieved articles were scanned to find further articles. Language was not used as an exclusion criterion. A total of 14 articles (N=55 231) were included in a meta-analysis on bullying and overweight youths, and a total of 16 articles (N=58 520) were included in a meta-analysis on bullying and obese youths. The results suggested that both overweight and obese youths were more likely to be victims of bullying. The results were not moderated by gender, overweight and obese boys and girls were equally likely to be victimized. Results remained significant after adjustment for publication bias. Both overweight and obesity are risk factors for being a victim of bullying.

    Our focus was on the determination of the growing number of youths of every race and ethnicity, diagnosed with obesity and its co-morbidities in the Caribbean. We reviewed the causes and strategies to combat obesity, and the implications of the fast food industry in enabling the escalation of obesity. We consulted several databases such as PubMed, MEDLINE, the Obesity Gene Map Database, and the USEPA Toxicity Reference Database. Organizations such as the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), Organization for Economic Co-operation and Development (OECD) and the Pan American Health Organization (PAHO) were used as information sources. Transgenerational effects and triggers like obesogens, pathogens, environmental stress, antibiotics and gut microbiota are some of the causes of obesity, and some of these triggers are imprinted epigenetically early in embryonic development, leading to lifelong obesity. With an estimated population of 42 million in the Caribbean, the economic cost of obesity, including medical, absenteeism, presenteeism, insurance, disability, direct and indirect cost, was estimated cost of 68.5 billion USD with 88.2 million quality-adjusted life years lost. Genome-wide association studies have established that genetics play a role in the aetiology of this "non-communicable" disease. While the development of personalized interventions according to genotype is futuristic, we must focus on effective nutrition and physical education classes in schools and establishing monitoring programmes using simple tools such as scales and tape measures as suggested intervention. A Pigovian tax to control the fast food industry is mandatory. Nevertheless, lifestyle adjustment, including alterations in diet and increased physical activity, continues to be a sound recommendation.

    Effective school-based obesity prevention programs are needed to prevent and reduce the growing obesity risk among youth. Utilizing the evidence-rich areas of violence and substance use prevention, translation science may provide an efficient means for developing curricula across multiple health behaviors. This paper introduces Pathways to Health, a school-based obesity prevention program that was developed by translating from evidence-based violence and drug use prevention programs, Promoting Alternative THinking Strategies and the Midwestern Prevention Project STAR (STAR). We illustrate how a hypothesized underlying behavior change mechanism in two domains of risk behavior, violence and substance use, can be applied to obesity prevention. A 4-step translational process is provided and may be relevant for use in developing other curricula to address multiple health risk behaviors. Practical application and decision points are also provided.

    Background Childhood obesity rates in minority populations continue to rise despite leveling national trends. Although interventions that address social and environmental factors exist, processes that create demand for policy and environmental change within communities have not been identified. Community Context We developed a pilot program in South Omaha, a Nebraska Latino community, based on the community readiness model (CRM), called SaludableOmaha. We used CRM to explore the potential of youth advocacy to shift individual and community norms regarding obesity prevention in South Omaha and to advocate for health-promoting community environments. Methods We used CRM to assess supply and demand for health programs, engage the community, determine the community’s baseline readiness to address childhood obesity, and guide youth advocacy program development. We conducted our project in 2 phases. In the first, we trained a cohort of youth. In the second, the youth cohort created and launched a Latino health movement, branded as SaludableOmaha. A third phase, which is currently under way, is directed at institutionalizing youth advocacy in communities. Outcome At baseline, the community studied was at a low stage of readiness for change. Our program generated infrastructure and materials to support the growth and institutionalization of youth advocacy as a means of increasing community readiness for addressing obesity prevention. Interpretation CRM is an important tool for addressing issues such as childhood obesity in underserved communities because it provides a framework for matching interventions to the community. Community partnerships such as SaludableOmaha can aid the adoption of obesity prevention programs. PMID:23217590

    Abstract Background: Currently, over 30% of US youth are overweight and 1 in 6 have metabolic syndrome, making youth obesity one of the major global health challenges of the 21st century. Few enduring treatment strategies have been identified in youth populations, and the majority of standard weight loss programs fail to adequately address the impact of psychological factors on eating behavior and the beneficial contribution of parental involvement in youth behavior change. Methods: A critical need exists to expand treatment development efforts beyond traditional education and cognitive-behavioral programs and explore alternative treatment models for youth obesity. Meditation-based mindful eating programs represent a unique and novel scientific approach to the current youth obesity epidemic given that they address key psychological variables affecting weight. Results: The recent expansion of mindfulness programs to include family relationships shows the immense potential for broadening the customarily individual focus of this intervention to include contextual factors thought to influence youth health outcomes. Conclusions: This article provides an overview of how both mindful eating and family systems theory fits within a conceptual framework in order to guide development of a comprehensive family-based mindful eating program for overweight youth.

    Obesity in children has increased in recent years throughout the world and is associated with adverse health consequences. Early interventions, including appropriate pedagogy strategies, are important for a successful intervention program. The aim of this study was to assess changes in body mass index, the ability to perform sport activities, behavior in the classroom and academic performance following one year of a health-wellness intervention program in obese youth. The CEMHaVi program included 37 obese children (19 girls and 18 boys). Participants received an intervention program consisting of physical activity and health education. Assessment included body mass index, academic performance, classroom performance and ability to perform sport activities. Paired t tests were used to assess the effects of intervention, and chi square was used to assess inter-action between measures. Findings of the study suggest significant decrease in Z scores of Body Mass Index and an improvement of academic performance, classroom behavior and the ability to perform sport activities (p < 0.05). Chi square testing showed significant positive inter-actions between body mass index, classroom behavior and academic performance. Results following year one of CEMHaVi showed that a program of physical activity and health education had positive effects on obesity, behavior in the classroom and the ability to perform sport activities in obese adolescents. Significant inter-action in changes between variables was observed. Findings are important for designing intervention models to improve health in obese youth.

    The Family Nutrition and Physical Activity Screening Tool (FNPA) evaluates family behavioural and environmental factors associated with pediatric obesity, but it is unknown if FNPA scores differ among youth across obesity severities. Our aim was to determine the association between the FNPA and obesity severity in youth referred to weight management. Upon initiating treatment, height, weight, and the FNPA were collected according to standard procedures. Cut-points for overweight/obesity, severe obesity (SO) class 2, and SO class 3 were calculated. FNPA scores were compared across weight status groups using analysis of covariance, and odds of SO across FNPA quartiles were evaluated with multiple logistic regression. Participants included 564 5-18year old who initiated treatment and completed the FNPA. After adjustment, FNPA scores differed by weight status with higher/healthier scores in youth with overweight/obesity (56.6±8.5) when compared to those with SO class 2 (55.0±7.1; p=0.015) or SO class 3 (53.6±9.0; p<0.001). Compared to those in the highest FNPA quartile, youth in the 2nd quartile had 1.8 (95% CI: 1.1, 2.9) times higher odds of SO, and those in the lowest FNPA quartile had 2.1 (95% CI: 1.3, 3.4) times higher odds of SO. Youth with SO had unhealthier subscale scores among 6 of 10 constructs, including nutritional, physical activity, sedentary, and sleep behaviours. Results suggest a consistent inverse relationship between the FNPA and adiposity among youth presenting for weight management. The FNPA is a useful metric for programs and clinicians targeting family behaviours and the home environment to combat obesity. Copyright © 2016 Asia Oceania Association for the Study of Obesity.

    The current increase in childhood type 1 diabetes (T1D) and obesity has led to two conflicting hypotheses and conflicting reports regarding the effects of overweight on initiation and spreading of islet cell autoimmunity vs earlier clinical manifestation of preexisting autoimmune β-cell damage driven by excess weight. The objective of the study was to address the question of whether the degree of β-cell autoimmunity and age are related to overweight at diabetes onset in a large cohort of T1D youth. This was a prospective cross-sectional study of youth with autoimmune T1D consecutively recruited at diabetes onset. The study was conducted at a regional academic pediatric diabetes center. Two hundred sixty-three consecutive children younger than 19 years at onset of T1D participated in the study. Relationships between body mass index and central obesity (waist circumference and waist to height ratio) and antigen spreading (islet cell autoantibody number), age, and cardiovascular (CVD) risk factors examined at onset and/or 3 months after the diagnosis were measured. There were no significant associations between number of autoantibodies with measures of adiposity. Age relationships revealed that a greater proportion of those with central obesity (21%) were in the youngest age group (0-4 y) compared with those without central obesity (6%) (P = .001). PATIENTS with central obesity had increased CVD risk factors and higher onset C-peptide levels (P < .05). No evidence was found to support the concept that obesity accelerates progression of autoantibody spreading once autoimmunity, marked by standard islet cell autoantibody assays, is present. Central obesity was present in almost one-third of the subjects and was associated with early CVD risk markers already at onset.

    Prior studies indicate that chronic stress is associated with obesity in adults. However, whether parental/caregiver stress is associated with obesity in their offspring has not been widely examined in Hispanic/Latino populations. In this study, we evaluated the role of caregiver chronic stress on child obesity and whether home food environment or child lifestyle behaviors explained the association. The study included a sample of Hispanic/Latino youth and their caregivers (n = 473) from the Study of Latinos (SOL) Youth study and the Hispanic Community Health Study/SOL Sociocultural Study, which enrolled children aged 8-16 years from four cities (Bronx, Chicago, Miami, and San Diego), and provided assessments of adult chronic stress. Poisson regression models were used to assess the association between parental/caregiver stress and child obesity, adjusting for potential confounders. Twenty-two percent of caregivers did not report any chronic stressors, 48% reported 1-2, and 29% reported ≥3 stressors. The prevalence of obesity in youth increased with number of caregiver stressors from 23% among those without caregiver stressors to 35% among those with ≥3 stressors (p for trend 0.03). After model adjustment, youths whose caregivers reported ≥3 stressors were more likely to be obese than youths whose caregivers reported no stressors (prevalence ratio = 1.53; 95% confidence interval 1.01-2.32). This association was independent of food home environment, child diet quality, and child physical activity, but it was not independent of caregiver obesity. These findings suggest that parental/caregiver chronic stress is related to obesity in their children. Future research is needed to confirm this association in longitudinal studies and in other population groups.

    Although High-intensity interval training (HIIT) has shown its effectiveness in improving body composition, cardio-respiratory fitness and lipid profile in obese adults, evidences remain limited in overweight/obese youth. This study was conducted to investigate the effect of a 12-week HIIT program without caloric restriction on body composition and lipid profile among young overweight/obese men. Twenty healthy obese youth were randomly allocated into two groups; experimental group (HIIT) and control group. The HIIT program consisted in 3 exercises sessions per week (30 sec of work at 100% maximal aerobic velocity [MAV]) interspersed by 30 sec of active recovery at 50% MAV, starting by 15 repetitions to reach 27 by the end of the program. Aerobic capacity (MAV and maximum oxygen uptake [VO2max]), body composition (body mass index [BMI], waist circumference [WC], and fat mass percent) and lipid profile (triglycerides [TG] and total, high-density lipoprotein [HDL] and low-density lipoprotein [LDL] cholesterol) were determined before and after the HIIT program. Following 12 weeks of HIIT, WC, BMI (P<0.01), and fat mass percent (P<0.05) were significantly decreased. MAV and VO2max were significantly improved in the HIIT group, only. Total cholesterol (P<0.05) and TG (P<0.05) decreased significantly in the HIIT group, while LDL and HDL cholesterol levels remained unchanged in both groups. HIIT may be particularly useful in overweight/obese youth to improve body composition, aerobic fitness and lipid profile. PMID:29511662

    Prospective patient registries have been successfully utilized in several disease states with a goal of improving treatment approaches through multi-institutional collaboration. The prevalence of youth with severe obesity is at a historic high in the United States, yet evidence to guide effective weight management is limited. The Pediatric Obesity Weight Evaluation Registry (POWER) was established in 2013 to identify and promote effective intervention strategies for pediatric obesity. Sites in POWER provide multicomponent pediatric weight management (PWM) care for youth with obesity and collect a defined set of demographic and clinical parameters, which they regularly submit to the POWER Data Coordinating Center. A program profile survey was completed by sites to describe characteristics of the respective PWM programs. From January 2014 through December 2015, 26 US sites were enrolled in POWER and had submitted data on 3643 youth with obesity. Ninety-five percent were 6-18 years of age, 54% female, 32% nonwhite, 32% Hispanic, and 59% publicly insured. Over two-thirds had severe obesity. All sites included a medical provider and used weight status in their referral criteria. Other program characteristics varied widely between sites. POWER is an established national registry representing a diverse sample of youth with obesity participating in multicomponent PWM programs across the United States. Using high-quality data collection and a collaborative research infrastructure, POWER aims to contribute to the development of evidence-based guidelines for multicomponent PWM programs.

    Behavioral and psychiatric disorders are common in youth with rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD). We outline a rational approach to psychiatric treatment of a patient with a complex medical condition. We report the course of symptoms in a teen with ROHHAD, the inpatient treatment, and review current evidence for use of psychopharmacologic agents in youth with sleep and anxiety disturbances. A 14-year-old female began rapidly gaining weight as a preschooler, developed hormonal imbalance, and mixed sleep apnea. Consultation was requested after a month of ROHHAD exacerbation, with severe anxiety, insomnia, and auditory hallucinations. Olanzapine and citalopram were helpful in controlling the symptoms. Following discharge, the patient gained weight and olanzapine was discontinued. Lorazepam was started in coordination with pulmonary service. Relevant pharmacologic considerations included risk of respiratory suppression, history of paradoxical reaction to hypnotics, hepatic isoenzyme interactions and side effects of antipsychotics. Core symptoms of ROHHAD may precipitate psychiatric disorders. A systematic evidence-based approach to psychopharmacology is necessary in the setting of psychiatric consultation.

  10. Cardiovascular consequences of childhood obesity.

    McCrindle, Brian W

    2015-02-01

    Childhood and adolescent overweight and obesity is an important and increasingly prevalent public health problem in Canada and worldwide. High adiposity in youth is indicated in clinical practice by plotting body mass index on appropriate percentile charts normed for age and sex, although waist measures might be a further tool. High adiposity can lead to adiposopathy in youth, with associated increases in inflammation and oxidative stress, changes in adipokines, and endocrinopathy. This is manifest as cardiometabolic risk factors in similar patterns to those in noted in obese adults. Obesity and cardiometabolic risk factors have been shown to be associated with vascular changes indicative of early atherosclerosis, and ventricular hypertrophy, dilation, and dysfunction. These cardiovascular consequences are evident in youth, but childhood obesity is also predictive of similar consequences in adulthood. Childhood obesity and risk factors have been shown to track into adulthood and worsen in most individuals. The result is an exponential acceleration of atherosclerosis, which can be predicted to translate into an epidemic of premature cardiovascular disease and events. A change in paradigm is needed toward preventing and curing atherosclerosis and not just preventing cardiovascular disease. This would necessarily create an imperative for preventing and treating childhood obesity. Urgent attention, policy, and action are needed to avoid the enormous future social and health care costs associated with the cardiovascular consequences of obesity in youth.

    Objective To explore parental and home environmental facilitators of sugar-sweetened beverage (SSB) and water consumption among obese/overweight Latino youth. Methods Semi-structured interviews were conducted with 55 overweight/obese Latino youth aged 10-18 and 55 parents, recruited from school-based clinics and a school in one West-coast district. All youth consumed SSBs regularly and lived in a home where SSBs were available. We used qualitative methods to examine key themes around beliefs about SSBs and water, facilitators of SSB and water consumption, and barriers to reducing SSB consumption. Results A few parents and youth believed that sports drinks are healthy. Although nearly all felt that water is healthy, most parents and about half of youth thought that tap water is unsafe. About half of parent-child dyads had discordant beliefs regarding their perceptions of tap water. About half of parents believed that home-made culturally relevant drinks (e.g., aguas frescas), which typically contain sugar, fruit, and water, were healthy due to their “natural” ingredients. Participants cited home availability as a key factor in SSB consumption. About half of parents set no rules about SSB consumption at home. Among those with rules, most parent-child pairs differed on their beliefs about the content of the rules, and youth reported few consequences for breaking rules. Conclusions Obesity programs for Latino youth should address misconceptions around water, and discuss culturally relevant drinks and sports drinks as potential sources of weight gain. Healthcare providers can help parents set appropriate rules by educating about the risks of keeping SSBs at home. PMID:23680295

This descriptive study explores community-based risks for overweight and obesity among African American youth in a rural town in the Deep South. We used ecological theory in conjunction with embodiment theory to explore how upstream ecological factors may contribute to risk of overweight and obesity for African American youth in a rural town in the Deep South. We conducted and analyzed in-depth interviews with African American community members who interact with youth in varying contexts (home, school, church, community). Participants most commonly stated that race relations, poverty, and the built environment were barriers to maintaining a healthy weight. Findings suggested the need for rural, community-based interventions that target obesity at multiple ecological levels and incorporate issues related to race, poverty, and the built environment. More research is needed to determine how disparities in obesity are created and perpetuated in specific community contexts.

    Obesity in children has increased in recent years. Many studies with differing methodologies have been undertaken to treat obesity. The Control, Evaluation, and Modification of Lifestyles in Obese Youth (CEMHaVi) program is a unique 2-year health-wellness program of physical activity and health education for obese youth. Findings of this study represent results at 1-year follow-up. The purpose of this study was to evaluate the effects of the CEMHaVi program. Physician-referred subjects (N = 26) participated in the study, 14 girls (13.4 +/- 2.9 years) and 12 boys (12.3 +/- 2.8 years). Measurements included height, weight, body mass index (BMI), academic performance, sleep habits, and health knowledge. The intervention consisted of a unique program of physical activity, including a variety of games specifically selected to be enjoyable, maintain interest, and motivate subjects to adhere. Activity sessions were offered once per week, 2 hours each session, for 12 months. A health education program was offered once every 3 months for 2 hours per session. Health knowledge, academic performance, self-esteem, and sleep were assessed before and after the intervention. Means were calculated at baseline and following intervention and were compared by paired t tests. Findings suggest significant improvements in academic performance (P < .001), quality and quantity of sleep (P < .05), and obesity (P < .05). The program reduced BMI and improved health knowledge, sleep, and academic performance in obese children. The feasibility of a beneficial lifestyle intervention program is encouraging in addressing obesity and related issues in young boys and girls.

    Physical activity (PA) promotes health in obese youth and is an important adjunct to medical weight management. Access to structured fitness programmes for obese, low-income youth is limited and potential benefits of such programmes are poorly understood. We describe an urban afterschool fitness programme for obese youth and participants' changes in fitness and body composition. A case series of 30 youth (age: 11.5 ± 2.5 years) with BMI ≥95th percentile and physician referral received a 24-wk programme scholarship. The programme, offered 4 times a week for 90-min.session, included aerobic, strength, and self-organised PA. Primary outcomes, measured at baseline (BL) time 1 (4-8 wk) and time 2 (12-16 wk) were BMI, per cent body fat (%BF), fat-free mass (FFM), heart rate during a treadmill test, and muscular strength (one repetition maximum (1RM)) and endurance (reps at 70% of 1RM) on the leg press (LP) and chest press (CP). Average participation was 1.5 ± 0.6 visits per week for 18.7 ± 6.5 weeks. Between BL and time 2, LP and CP 1RM and endurance significantly improved (P < 0.05). Additionally, there was a significant interaction for %BF with boys losing 5.2% (P > 0.05) while girls lost 0% (>0.05). Obese youth attending an urban fitness programme for at least three months improved strength and body composition, but average attendance was below planned levels.

    Obesity and regional fat distribution, measured by neck fat mass percentage using dual-energy X-ray absorptiometry (DXA), correlate with obstructive sleep apnea (OSA) severity in adults. In obese children, neck-to-waist-circumference ratio predicts OSA. This study examined associations between body fat percentage and distribution and sleep-disordered breathing (SDB) severity in obese youth, measured with DXA. Cross-sectional retrospective study conducted at a tertiary children's hospital. Participants were aged 6 to 18 years with obesity (body mass index [BMI] > 99th percentile [BMI z-score 2.35] or > 95th percentile with comorbidity). They underwent polysomnography and DXA to quantify body fat percentage and distribution ratios (neck-to-abdominal fat percentage [NAF % ratio]). SDB was defined as apnea-hypopnea index (AHI) > 5 and OSA as obstructive AHI (OAHI) > 1 event/h. Relationships of BMI z-score and NAF % ratio to log AHI and log OAHI were evaluated. Thirty individuals participated; 18 male; median age 14.1 years. Twenty-four individuals had BMI z-scores > 2.35. Ten had AHI > 5 events/h. NAF % ratio was significantly associated with log AHI in males and with log OAHI in all, whereas total fat mass percent was not. The association between log OAHI and NAF % ratio was significant in males, but not females. NAF % ratio was significantly associated with log OAHI in those with BMI z-score above 2.35. NAF % ratio was associated with OSA severity in males and youth with BMI > 99th percentile; however, total fat mass percentage was not, suggesting that body fat distribution is associated with OSA risk in youth. © 2017 American Academy of Sleep Medicine

    Examine relations between depressive symptoms, ethnic identity, and health-related quality of life (HRQOL) in overweight or obese (OV/OB) children. A total of 166 OV/OB 8- to 17-year-olds (M = 12.94 years; 86.7% obese; 50.6% racial/ethnic minority) attending an outpatient pediatric obesity medical clinic participated. Children completed the Children's Depression Inventory-Short Form, Multigroup Ethnic Identity Measure (MEIM), and Pediatric Quality of Life Inventory. Increased depressive symptoms significantly predicted reduced total, physical, and psychosocial HRQOL. For minority OV/OB youth only, MEIM Affirmation/Belonging moderated depressive symptoms and total HRQOL (effect = -2.59, t = -2.24, p = .027; R(2) overall model = 0.315) and depressive symptoms and psychosocial HRQOL (effect = -3.01, t = -2.47, p = .015; R(2) overall model = 0.331). Depressive symptoms are negatively associated with HRQOL. In minority OV/OB youth, high ethnic identity may be protective when depressive symptoms are minimal. Ethnic identity and other cultural factors are important to consider in psychosocial treatments for pediatric obesity. © The Author 2015.

    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.

    Investigators developed a review system to evaluate the growing literature on policy and environmental strategies to prevent childhood obesity. Over 2000 documents published between January 2000 and May 2009 in the scientific and grey literature were identified (2008–2009) and systematically analyzed (2009–2012). These focused on policy or environmental strategies to reduce obesity/overweight, increase physical activity, and/or improve nutrition/diet among youth (aged 3–18 years). Guided by the RE-AIM framework, investigators abstracted studies of 24 intervention strategies and assessed evidence for their effectiveness (i.e., study design, intervention duration, and outcomes) and population impact (i.e., effectiveness and reach – participation or exposure, and representativeness) in 142 evaluation study groupings and 254 associational study groupings (n=396 groupings of 600 peer-reviewed studies). The 24 strategies yielded 25 classifications (school wellness policies yielded nutrition and physical activity classifications): 1st-tier effective (n=5); 2nd-tier effective (n=6); “promising” (n=5); or “emerging” (n=9). Evidence for intervention effectiveness was reported in 56% of the evaluation, and 77% of the associational, study groupings. Among the evaluation study groupings, only 49% reported sufficient data for population impact ratings, and only 22% qualified for a rating of high population impact. Effectiveness and impact ratings were summarized in graphic evidence maps, displaying effects/associations with behavioral and obesity/overweight outcomes. This paper describes the results and products of the review, with recommendations for policy research and practice. PMID:24355679

    This study aimed to determine the prevalence of and risk factors associated with elevated alanine aminotransferase (ALT) levels among a sample of normal weight, overweight and obese youth from two urban populations in Central Mexico. Baseline data from 1262 youth aged 8-19 years who participated in the Mexican Health Worker Cohort Study from March 2004 to April 2006 were reviewed, including 680 girls and 582 boys, with a total of 83 participants with elevated ALT level (>40 U/L). Information was obtained from self-administered questionnaires, anthropometric results and clinical measurements. Associations of interest were examined using multivariate logistic regression models. A total of 3.8% of girls and 9.8% of boys had elevated ALT levels. Elevated ALT was observed in 28.9% of the obese and 14.2% of the overweight participants. Metabolic syndrome (MS) occurred in 6.1% of the study population and those with MS had a high percentage of elevated ALT (14.5% of girls and 40.0% of boys, respectively). Abdominal obesity and insulin resistance were also associated with a greater risk of elevated ALT. Obesity and certain metabolic risk factors are important predictors for elevated ALT. Screening for ALT levels in obese youth could help to identify those at risk and reduce the possibility of future liver diseases. © 2013 Wiley Publishing Asia Pty Ltd and Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine.

    Abstract Background: Type 2 diabetes mellitus (T2DM) and prediabetes have increased in prevalence among overweight and obese children, with significant implications for long-term health. There is little published evidence on the best approaches to care of prediabetes among overweight youth or the current practices used across pediatric weight management programs. Methods: This article reviews the literature and summarizes current practices for screening, diagnosis, and treatment of prediabetes at childhood obesity treatment centers. Findings regarding current practice were based on responses to an online survey from 28 pediatric weight management programs at 25 children's hospitals in 2012. Based on the literature reviewed, and empiric data, consensus support statements on prediabetes care and T2DM prevention were developed among representatives of these 25 children's hospitals' obesity clinics. Results: The evidence reviewed demonstrates that current T2DM and prediabetes diagnostic parameters are derived from adult-based studies with little understanding of clinical outcomes among youth. Very limited evidence exists on preventing progression of prediabetes. Some evidence suggests that a significant proportion of obese youth with prediabetes will revert to normoglycemia without pharmacological management. Evidence supports lifestyle modification for children with prediabetes, but further study of specific lifestyle changes and pharmacological treatments is needed. Conclusion: Evidence to guide management of prediabetes in children is limited. Current practice patterns of pediatric weight management programs show areas of variability in practice, reflecting the limited evidence base. More research is needed to guide clinical care for overweight youth with prediabetes. PMID:25055134

    The purpose of this meta-analysis was to examine the evidence for the effectiveness of aerobic exercise interventions on reducing insulin resistance markers in obese children and/or adolescents. A secondary outcome was change in percentage of body fat. A computerized search was made from seven databases: CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, ERIC, MEDLINE, PsycINFO, and Science Citation Index. The analysis was restricted to randomized controlled trials that examined the effect of aerobic exercise on insulin resistance markers in obese youth. Two independent reviewers screened studies and extracted data. Effect sizes (ES) and 95% confidence interval (CI) were calculated, and the heterogeneity of the studies was estimated using Cochran's Q-statistic. Nine studies were selected for meta-analysis as they fulfilled the inclusion criteria (n=367). Aerobic exercise interventions resulted in decreases in fasting glucose (ES=-0.39; low heterogeneity) and insulin (ES=-0.40; low heterogeneity) and in percentage of body fat (ES=-0.35; low heterogeneity). These improvements were specifically accentuated in adolescents (only in fasting insulin), or through programs lasting more than 12 weeks, three sessions per week, and over 60 min of aerobic exercise per session. This meta-analysis provides insights into the effectiveness of aerobic exercise interventions on insulin resistance markers in the obese youth population. © 2014 European Society of Endocrinology.

    Physical activity (PA), television time (TV), and sleep duration (SLP) are considered individual risk factors for adolescent obesity. Our aim was to investigate the concurrent influence of meeting PA, SLP, and TV recommendations on adolescent obesity utilizing 2011 Youth Risk Behavior Surveillance Survey (YRBSS) data. Subjects included 9589 (4874 females) high school students. PA, SLP, and TV were categorized utilizing established national recommendations and youth were cross-tabulated into 1 of 8 groups based on meeting or not meeting each recommendation. Logistic models were used to examine the odds of obesity for each group. Youth meeting the PA recommendation were not at increased odds of obesity, regardless of SLP or TV status. However, not meeting any single recommendation, in general, led to increased odds of not meeting the other two. In boys, 11.8% met all recommendations while 14.1% met 0 recommendations. In girls, only 5.0% met all recommendations while 17.8% met none. Boys and girls not meeting any of the recommendations were 4.0 and 3.8 times more likely to be obese compared with their respective referent groups. Further research considering the simultaneous influence these risk factors may have on obesity and on one another is warranted.

    Youth advocacy for obesity prevention is a promising but under-evaluated intervention. The aims of this study are to evaluate a youth advocacy program's outcomes related to youth perceptions and behaviors, develop an index of youth advocacy readiness, and assess potential predictors of advocacy readiness. Youth ages 9-22 in an advocacy training program (n = 92 matched pairs) completed surveys before and after training. Youth outcomes and potential predictors of advocacy readiness were assessed with evaluated scales. All 20 groups who completed the evaluation study presented their advocacy projects to a decision maker. Two of six perception subscales increased following participation in the advocacy program: self-efficacy for advocacy behaviors (p < .001) and participation in advocacy (p < .01). Four of five knowledge and skills subscales increased: assertiveness (p < .01), health advocacy history (p < .001), knowledge of resources (p < .01), and social support for health behaviors (p < .001). Youth increased days of meeting physical activity recommendations (p < .05). In a mixed regression model, four subscales were associated with the advocacy readiness index: optimism for change (B = 1.46, 95 % CI = .49-2.44), sports and physical activity enjoyment (B = .55, 95 % CI = .05-1.05), roles and participation (B = 1.81, 95 % CI = .60-3.02), and advocacy activities (B = 1.49, 95 % CI = .64-2.32). The youth advocacy readiness index is a novel way to determine the effects of multiple correlates of advocacy readiness. Childhood obesity-related advocacy training appeared to improve youths' readiness for advocacy and physical activity.

    Parks and park features are important for promoting physical activity and healthy weight, especially for low-income and racial/ethnic minority youth who have disproportionately high obesity rates. This study 1) examined associations between neighborhood park and playground availability and youth obesity, and 2) assessed whether these associations were moderated by youth race/ethnicity and socioeconomic status (SES). In 2013, objectively measured height and weight were collected for all 3rd-5th grade youth (n=13.469) in a southeastern US county to determine body mass index (BMI) percentiles. Enumeration and audits of the county's parks (n=103) were concurrently conducted. Neighborhood park and playground availability were calculated as the number of each facility within or intersecting each youth's Census block group. Multilevel linear regression models were utilized to examine study objectives. For boys, no main effects were detected; however, SES moderated associations such that higher park availability was associated with lower BMI percentile for low-SES youth but higher BMI percentile for high-SES youth. For girls, the number of parks and playgrounds were significantly associated with lower BMI (b=-2.2, b=-1.1, p<0.05, respectively) and race/ethnicity and SES moderated associations between playground availability and BMI percentile. Higher playground availability was associated with lower BMI percentile for White and high-SES girls but higher BMI percentile for African American and low-SES girls. Considerable variation was detected in associations between park and playground availability and youth obesity by SES and race/ethnicity, highlighting the importance of studying the intersection of these characteristics when exploring associations between built environment features and obesity.

    To examine the effect of participation in a summer camp focused on nutrition and fitness among low-income youth. In 2011-2012, overweight and obese youth (n = 126) from Fresno, CA participated in a free 6-week summer program, Healthy Lifestyle Fitness Camp (HLFC), which included 3 h/wk of nutrition education provided by University of California CalFresh and 3 hours of daily physical activity through Fresno Parks and Recreation. The researchers used repeated-measures ANOVA to examine changes in weight, waist circumference, and waist-to-height ratio (WHtR) between HLFC and the comparison group (n = 29). Significant pre-post WHtR reductions were observed in HLFC: 0.64 to 0.61 (P < .001). In addition, WHtR reductions were maintained in HLFC 2 months afterward whereas an increase occurred in the comparison group (P < .007). Understanding the impact of nutrition- and fitness-themed summer camps during unstructured months of summer is integral to obesity prevention among low-income youth.

    This longitudinal study identified common summer care arrangements for adolescents and examined whether those arrangements predicted risk for obesity (Body Mass Index (BMI) ≥ 85th percentile for age and gender) the following school year. Participants were a nationally representative sample of 1,766 adolescents ages 10–18 from the Panel Study of Income Dynamics-Child Development Supplement. Results showed that, beyond measures of BMI taken before the summer and several demographic aspects known to predict obesity, youth whose summer arrangements involved regular participation in organized activities (e.g., sports) showed significantly lower risk for obesity than other youth. This was most evident during early adolescence. Youth whose regular summer arrangement was predominated by parent care without organized activity participation showed the greatest risk for obesity.

    OBJECTIVE—To estimate the prevalence and incidence of diabetes, clinical characteristics, and risk factors for chronic complications among Navajo youth, using data collected by the SEARCH for Diabetes in Youth Study (SEARCH study). RESEARCH DESIGN AND METHODS—The SEARCH study identified all prevalent cases of diabetes in 2001 and all incident cases in 2002–2005 among Navajo youth. We estimated denominators with the user population for eligible health care facilities. Youth with diabetes also attended a research visit that included questionnaires, physical examination, blood and urine collection, and extended medical record abstraction. RESULTS—Diabetes is infrequent among Navajo youth aged <10 years. However, both prevalence and incidence of diabetes are high in older youth. Among adolescents aged 15–19 years, 1 in 359 Navajo youth had diabetes in 2001 and 1 in 2,542 developed diabetes annually. The vast majority of diabetes among Navajo youth with diabetes is type 2, although type 1 diabetes is also present, especially among younger children. Navajo youth with either diabetes type were likely to have poor glycemic control, high prevalence of unhealthy behaviors, and evidence of severely depressed mood. Youth with type 2 diabetes had more metabolic factors associated with obesity and insulin resistance (abdominal fat deposition, dyslipidemia, and higher albumin-to-creatinine ratio) than youth with type 1 diabetes. CONCLUSIONS—Our data provide evidence that diabetes is an important health problem for Navajo youth. Targeted efforts aimed at primary prevention of diabetes in Navajo youth and efforts to prevent or delay the development of chronic complications among those with diabetes are warranted.

    2012-01-01

    The frequency of overweight and obesity among North American Indian children and youth exceeds that of other ethnic groups in the United States. This observation is based on studies using body mass index as the primary measure of overweight and obesity. In the mid-20th century, there were regional differences among North American Indian groups in sub-adults’ size and shape and only a few Southwestern groups were characterized by high rates of overweight and obesity. In most populations, the high prevalence of overweight and obesity developed in the last decades of the 20th century. Childhood obesity may begin early in life as many studies report higher birth weights and greater weight-for-height in the preschool years. Contributing factors include higher maternal weights, a nutritional transition from locally caught or raised foods to store bought items, psychosocial stress associated with threats to cultural identity and national sovereignty, and exposure to obesogenic pollutants, all associated to some degree with poverty. Obesity is part of the profile of poor health among Native Americans in the US and Canada, and contributes to woefully high rates of diabetes, cardiovascular disease, and early mortality. Interventions that are culturally appropriate are needed to reduce weights at all points in the lifespan. PMID:22378356

    This study aims to validate an obesity-specific health-related quality of life (HRQOL) measure, Sizing Me Up (SMU), in treatment-seeking Latino youth. Pediatric obesity has been associated with reduced HRQOL; therefore, valid measures are important for use in diverse populations that may be at increased risk for obesity and related comorbidities. Structural equation modeling tested the fit of the 5-subscale, 22-item SMU measure in Latino youth, 5-13 years of age, with obesity ( N = 204). Invariance testing was conducted to examine equivalence between Latino and non-Latino groups ( N = 250). SMU achieved acceptable fit in a Latino population [χ 2 = 428.33, df = 199, p < .001, Root Mean Squared Error of Approximation = 0.072 (0.062-0.082), Comparative Fit Index = 0.915, Tucker-Lewis Index = 0.901, Weighted Root Mean Square Residual = 1.2230]. Additionally, factor structure and factor loadings were invariant across Latino and non-Latino groups, but thresholds were not invariant. SMU is a valid measure of obesity-specific HRQOL in treatment-seeking Latino youth with obesity. © The Author 2016.

    This paper reports the process data on program fidelity, best practices for intervention implementation, youth and coach engagement, and youth application of knowledge and skills for the two-year WAVE~Ripples for Change (WAVE) obesity prevention intervention program focused on healthy eating, physical activity, and life skills with high school (HS) soccer players aged 14⁻19 years. Internal (staff: n = 7; volunteers: n = 27) and external (youth: n = 100; coaches: n = 9) stakeholders were interviewed/ surveyed. Staff rated program fidelity as high (94%), as did volunteers (85%). Best practices included coach encouragement for athlete participation, use of on-line consent for enrollment, building relationships with HS staff to complete assessments, sending text reminders, and providing incentives. Study results showed an enrollment rate of 72%, completion of baseline assessments of 89⁻98%, attendance of sports nutrition lessons in Year 1 and Year 2 of 90% and 39%, respectively, and team-building workshop (TBW) attendance of 25⁻31%. Activities exceeding youth expectations (>90%) included, (1) activities with their soccer team; (2) the TBW-cooking; and (3) sports nutrition lessons. The obesity prevention skills most applied by youth were obtained from the TBW-gardening and harvesting (49%), the TBW-cooking (43%), and sports nutrition lessons (44%). Coaches also rated the sports nutrition lessons highly and reported increased awareness for hydration/fueling during sport by the athletes. Using sport teams/clubs to engage youth in obesity prevention is a feasible model for future study.

    Obesity and morbid obesity are associated with many physiological changes affecting pharmacokinetics, such as increased blood volume, cardiac output, splanchnic blood flow, and hepatic blood flow. In obesity, drug absorption appears unaltered, although recent evidence suggests that this conclusion may be premature. Volume of distribution may vary largely, but the magnitude and direction of changes seem difficult to predict, with extrapolation on the basis of total body weight being the best approach to date. Changes in clearance may be smaller than in distribution, whereas there is growing evidence that the influence of obesity on clearance can be predicted on the basis of reported changes in the metabolic or elimination pathways involved. For obese children, we propose two methods to distinguish between developmental and obesity-related changes. Future research should focus on the characterization of physiological concepts to predict the optimal dose for each drug in the obese population.

    We evaluated whether the triglyceride-to-HDL cholesterol (TG/HDL-C) ratio is associated with insulin resistance (IR) in a large multiethnic cohort of obese youths. Obese youths (1,452) had an oral glucose tolerance test and a fasting lipid profile. Insulin sensitivity was estimated using the whole body insulin sensitivity index (WBISI) and homeostasis model assessment (HOMA)-IR and evaluated, in a subgroup of 146 obese youths, by the hyperinsulinemic-euglycemic clamp. The cohort was divided by ethnicity (612 whites, 357 Hispanics, and 483 African Americans) and then stratified into ethnicity-specific tertiles of TG/HDL-C ratio. Differences across tertiles were evaluated, and the association between the TG/HDL-C ratio and insulin sensitivity (WBISI) was defined by a multiple stepwise linear regression analysis. The area under the receiver operating characteristic (ROC) curve (AUC) was determined to calculate the TG/HDL-C ratio cutoff to identify insulin-resistant subjects by ethnicity. In each ethnic group and across rising tertiles of TG/HDL-C ratio, insulin sensitivity (WBISI) progressively decreased, whereas 2-h glucose and the AUC-glucose progressively increased. The cutoff for TG/HDL-C ratio was 2.27, and the odds of presenting with IR, in youths with TG/HDL-C ratio higher than the cutoff, was 6.023 (95% CI 2.798-12.964; P < 0.001) in white girls and boys, whereas for both Hispanics and African Americans the AUC-ROCs were not significant, thus not allowing the calculation of an optimal cutoff TG/HDL-C value. The TG/HDL-C ratio is associated with IR mainly in white obese boys and girls and thus may be used with other risk factors to identify subjects at increased risk of IR-driven morbidity.

    This review considers the epidemiologic evidence of an increasing incidence of type 2 diabetes in youth, the classification and diagnostic issues related to diabetes in young populations, pathophysiologic mechanisms relevant to the increasing incidence, the role of genetics and environment, and the community challenge for prevention and treatment. Type 2 diabetes in youth has been recognized to be frequent in populations of native North Americans and to comprise some 30 percent of new cases of diabetes in the 2nd decade of life, largely accounted for by minority populations and associated with obesity. Among Japanese schoolchildren, type 2 diabetes is seven times more common than type 1, and its incidence has increased more than 30-fold over the past 20 years, concomitant with changing food patterns and increasing obesity rates. The forms of diabetes seen in children and youth include typical type 1, occurring in all races; type 2, seen predominantly in minority youth; atypical diabetes, seen as an autosomal dominantly transmitted disorder in African-American populations; and maturity-onset diabetes of the young (MODY), seen rarely and only in Caucasians. Of the nonautoimmune forms of diabetes seen in youth, only type 2 diabetes is increasing in incidence. Proper classification requires consideration of onset (acute/severe versus insidious), ethnicity, family history, presence of obesity, and if necessary, studies of diabetes related autoimmunity. Insulin resistance predicts the development of diabetes in Pima Indians, in offspring of parents with type 2 diabetes, and in other high-risk populations. African-American children and youth have greater insulin responses during glucose tolerance testing and during hyperglycemic clamp study than do whites. There is also evidence of altered beta-cell function preceding the development of hyperglycemia. Of particular interest is the evidence that abnormal fetal and infantile nutrition is associated with the development of

    Low-income youth are at increased risk for excess weight gain. Although evidence-based prevention programs exist, successful adaptation to provide wide dissemination presents a challenge. Hip-Hop to Health (HH) is a school-based obesity prevention intervention that targets primarily preschool children of low-income families. In a large randomized controlled trial, HH was found to be efficacious for prevention of excessive weight gain. The Expanded Food and Nutrition Education Program (EFNEP) and the Supplemental Nutrition Assistance Program-Education (SNAP-Ed) are USDA-funded nutrition education programs offered to low-income families, and may provide an ideal platform for the wide dissemination of evidence-based obesity prevention programs. A research-practice partnership was established in order to conduct formative research to guide the adaptation and implementation of HH through EFNEP and SNAP-Ed. We present the design and method of a comparative effectiveness trial that will determine the efficacy of HH when delivered by peer educators through these programs compared to the standard EFNEP and SNAP-Ed nutrition education (NE) curriculum. Results from this trial will inform larger scale dissemination. The dissemination of HH through government programs has the potential to increase the reach of efficacious obesity prevention programs that target low-income children and families.

    Child and adolescent overweight and obesity are independent risk factors for poor social outcomes. Whether children who are overweight display greater bullying behaviors than normal weight peers, controlling for demographic and other social-ecological factors, was examined. The influence of child (e.g., mental health), family (e.g., income, parent mental health, and exposure to domestic violence), and community (e.g., exposure to neighborhood violence, unfair treatment based on race or ethnic group) factors on bullying risk in the subset of children who are overweight and obese was explored. We conducted a secondary data analysis of the 2011-2012 National Survey of Children's Health, a cross-sectional study providing a nationally representative sample of participants, using a series of multinomial logistic regressions in Mplus software (Muthén & Muthén, Los Angeles, CA). Participants were 41,361 youth ages 10-17 years. Despite statistically significant differences in unadjusted analyses, no differences were found in bullying behavior by weight status once controlling for other factors. Child, family, and neighborhood factors predicted bullying behavior in both the overall sample and the subset of overweight and obese youth. However, some risk factors were unique to children who were overweight or obese. Children who are overweight or obese are not at greater risk for engaging in bullying behavior than normal weight peers. Health professionals targeting bullying behavior should be aware of the impact child, family, and neighborhood factors have on bullying by overweight and obese children and adolescents.

    Recently, there has been growing interest in high-intensity interval training (HIT) as a strategy to improve health. In this pilot study, we examined the feasibility of a 4-week low-volume HIT and its effects on cardiorespiratory fitness (CRF), blood pressure (BP) and enjoyment in overweight and obese youth. Twelve adolescents (body mass index (BMI): 34.8 ± 3.9 kg · m ‒ 2 , 14.9 ± 1.5 years) participated in 12 sessions of HIT (10 × 60 s cycling bouts eliciting ~90% maximal heart rate, interspersed with 90 s recovery, 30 min/session, 3 sessions/week) over ~4 weeks. All the participants completed the study and exercise attendance averaged 92%. Despite no changes in body weight and total fat, HIT resulted in significant (P < 0.01) increases in CRF (pre: 20.1 versus post: 22.2 ml · kg ‒1 · min ‒1 ) and exercise time (pre: 425 versus post: 509 s) during peak oxygen uptake test, and a reduction in resting systolic BP (pre: 115.8 versus post: 107.6 mmHg). The majority of study participants (83%) enjoyed HIT and more than half of the participants (58%) reported that HIT is a more enjoyable form of exercise compared to other types of exercises. Low-volume HIT is a useful strategy to promote exercise participation and improve cardiovascular health in overweight and obese youth.

    Objectives To examine concurrent and prospective associations between perceptions of teasing and health-related quality of life (HRQOL) over the course of a behavioral/educational intervention and the subsequent year in a sample of overweight and obese children and adolescents. Method A clinical sample of 93 overweight or obese youths (ages 7–17 years) and 1 parent/guardian completed measures of teasing and HRQOL at pre- and posttreatment and follow-up assessments. Structural equation modeling was used to examine the factor structure of the measures and to assess prospective associations over a 15-month period. Results Results indicate that, concurrently, weight-related teasing is inversely associated with HRQOL and that, prospectively, HRQOL is inversely associated with subsequent teasing. Conclusions Study findings are suggestive of a directional relationship with lower quality of life predicting subsequent higher levels of teasing. Results suggest the potential for interventions designed to improve HRQOL to reduce teasing experiences for overweight and obese youth. PMID:22262915

    To investigate food assistance participation as a risk factor for overweight and obesity in youth, and food insecurity as an effect modifier. The sample included youth ages 4-17, in families ≤200% of the federal poverty line in the 2007-2008 National Health and Nutrition Examination Survey (n = 1321). Food insecurity was measured with the US Department of Agriculture survey module. Food assistance participation was assessed for Supplemental Nutrition Assistance Program, Special Supplemental Nutrition Program for Women, Infants and Children and school meals. Body size was classified by age- and sex-specific body mass index (BMI) percentile, BMI z-score and waist circumference percentile. Regression models with direct covariate adjustment and programme-specific propensity scores, stratified by food insecurity, estimated associations between food assistance participation and body size. Food assistance participation was not associated with increased body size among food-insecure youth in models with direct covariate adjustment or propensity scores. Compared with low-income, food-secure youth not participating in food assistance, BMI z-scores were higher among participants in models with direct covariate adjustment (0.27-0.38 SD and 0.41-0.47 SD, for boys and girls, respectively). Using propensity scores, results were similar for boys, but less so for girls. Food assistance programme participation is associated with increased body size in food-secure youth, but not food-insecure youth. Using both direct covariate adjustment and a propensity score approach, self-selection bias may explain some, but not all, of the associations. Providing healthy food assistance that improves diet quality without contributing to excessive intake remains an important public health goal. © 2013 The Authors.

    Severe obesity (SO) in pediatrics has become increasing prevalent in recent decades.The objective of our study was to examine differences in demographic, anthropometric, cardiometabolic, and lifestyle variables in children and youth with SO versus their less overweight/obese (OW/OB) peers. A retrospective medical record review of 6-19 year old participants enrolled in an outpatient pediatric weight management clinic was conducted. SO (body mass index [BMI] ≥99(th) percentile) and OW/OB (BMI ≥85(th) and <99(th) percentile) groups were created according to Centers for Disease Control and Prevention definitions. Demographic, anthropometric, cardiometabolic and lifestyle data reported at baseline (pre-intervention) were retrieved. Of the 345 participants, most were girls (56.2%), Caucasian (78.7%), and had family incomes > $50,000/year (65.7%). The SO group (n = 161) had lower HDL-cholesterol and higher liver enzymes, insulin resistance and blood pressure than the OW/OB group (n = 184; all p < 0.01). They also reported higher total energy intakes, fewer steps/day, less moderate-to-vigorous physical activity, and more leisure time screen time (all p < 0.02) than their leaner peers. Compared to the OW/OB group, a higher proportion of individuals in the SO group possessed cardiometabolic risk factors, including high triglycerides (45.8% vs 58.5%), alanine aminotransferase (55.4% vs 81.4%), insulin resistance (55.6% vs 82.1%), systolic blood pressure (11.5% vs 27.3%), diastolic blood pressure (17.8% vs 30.0%), and low HDL-cholesterol (44.6% vs 64.6%; all p < 0.02). Aside from the ~75% of participants (groups combined) who met the daily recommended intakes of grain and meat products, <50% of boys and girls met any of the remaining nutrition and physical activity-related recommendations. Compared to the OW/OB group, greater proportions of children and youth in the SO group failed to meet moderate-to-vigorous physical activity (48.4% vs 31.9%) and leisure

    Over the last decade, the evidence linking obesity to impaired reproductive function has grown. In this article, we review this evidence and discuss the underlying pathophysiology. Obese women are less likely than normal-weight women to achieve pregnancy. Female obesity adversely affects reproductive function through alterations in the hypothalamic-pituitary-ovarian axis, oocyte quality, and endometrial receptivity. It is unclear which mechanism contributes the most to subfecundity, and it is likely a cumulative process. Emerging data highlight the contribution of male obesity to impaired reproductive function and that couple obesity has synergistic adverse effects. Once pregnant, obese women are at higher risk for adverse pregnancy outcomes. Weight loss improves reproductive potential in obese patients. As obese women surpass 35 years of age, age may be more important than body mass index in determining reproductive potential. Obstetrician gynecologists need to be aware of the negative impact of obesity on reproductive function so that they appropriately counsel their patients. Further work is needed to clarify the underlying pathophysiology responsible for adverse effects of obesity on reproduction so that novel treatment approaches may be developed.

    Type 2 diabetes (T2D) disproportionately impacts Latino youth yet few diabetes prevention programs address this important source of health disparities. To address this knowledge gap, we describe the rationale, design, and methodology underpinning a culturally-grounded T2D prevention program for obese Latino youth. The study aims to: 1) to test the efficacy of the intervention for reducing T2D risk, 2) explore potential mediators and moderators of changes in health behaviors and health outcomes and, 3) examine the incremental cost-effectiveness for reducing T2D risk. Latino adolescents (N=160, age 14-16) will be randomized to either a 3-month intensive lifestyle intervention or a control condition. The intervention consists of weekly health education delivered by bilingual/bicultural promotores and 3 moderate-to-vigorous physical activity (PA) sessions/week. Control youth receive health information and results from their laboratory testing. Insulin sensitivity, glucose tolerance, and weight-specific quality of life are assessed at baseline, 3-months, 6-months, and 12-months. We will explore whether enhanced self-efficacy and/or social support mediate improvements in nutrition/PA behaviors and T2D outcomes. We will also explore whether effects are moderated by sex and/or acculturation. Cost-effectiveness from the health system perspective will be estimated by the incremental cost-effectiveness ratio using changes in insulin sensitivity at 12-months. The results of this study will provide much needed information on how T2D prevention interventions for obese Latino youth are developed, implemented and evaluated. This innovative approach is an essential step in the development of scalable, cost-effective, solution oriented programs to prevent T2D in this and other high-risk populations.

    Obesity prevalence varies by income and education level, although patterns might differ among adults and youths (1-3). Previous analyses of national data showed that the prevalence of childhood obesity by income and education of household head varied across race/Hispanic origin groups (4). CDC analyzed 2011-2014 data from the National Health and Nutrition Examination Survey (NHANES) to obtain estimates of childhood obesity prevalence by household income (≤130%, >130% to ≤350%, and >350% of the federal poverty level [FPL]) and head of household education level (high school graduate or less, some college, and college graduate). During 2011-2014 the prevalence of obesity among U.S. youths (persons aged 2-19 years) was 17.0%, and was lower in the highest income group (10.9%) than in the other groups (19.9% and 18.9%) and also lower in the highest education group (9.6%) than in the other groups (18.3% and 21.6%). Continued progress is needed to reduce disparities, a goal of Healthy People 2020. The overall Healthy People 2020 target for childhood obesity prevalence is <14.5% (5).

    The global pandemic of childhood obesity has led to increased risk for prediabetes and type 2 diabetes mellitus (T2DM). Studies have shown decreased insulin sensitivity and/or secretion with increasing adiposity and consistently observed greater risk for T2DM in obese, non-Caucasian youth. In the current review we describe recent advances in understanding how obesity and metabolic status in children and adolescents confers various risk profiles for T2DM among Latinos, African-Americans, Caucasians, Asians and Native Americans. These possible determinants include ectopic fat distribution, adipose tissue inflammation and fibrosis, and elevated plasma levels of non-esterified free fatty acids. Future work should aim to elucidate the ethnic-specific pathophysiology of T2DM in order to develop and implement appropriate prevention and treatment strategies based on different ethnic profiles of diabetes risk.

    This review aims to determine if acute exercise affects subsequent energy and macronutrients intake in obese and non-obese children and adolescents. Databases were searched between January 2015 and December 2015 for studies reporting energy and/or macronutrients intake immediately after an acute exercise and control condition, in children and adolescents. From the initial 118 references found, 14 were included for subsequent analysis after screening representing 31 acute exercise conditions that varied in intensity, duration and modality. One study found increased energy intake after exercise, seven decreased and 23 revealed no change. The meta-analysis revealed a significant effect of acute exercise on intake in obese but not in lean youth by a mean difference of -0.430 (95% confidence interval=-0.703 to -0.157, P=0.002) displaying low heterogeneity (I 2 =0.000; Q=5.875; d f =9, P=0.752). The analysis showed that intense exercise only reduces intake in obese children (no intensity effect in lean). Unchanged macronutrients intake was reported in nine studies as opposed to three which found modified lipids, protein and/or carbohydrate intake. Although acute exercise does not affect energy intake in lean, it appears to reduced food intake in obese youth when intense, without altering the macronutrients composition of the meal.

    The prevalence and severity of pediatric obesity have dramatically increased since the late 1980s, raising concerns about a subsequent increase in cardiovascular outcomes. Strong evidence, particularly from autopsy studies, supports the concept that precursors of adult cardiovascular disease (CVD) begin in childhood, and that pediatric obesity has an important influence on overall CVD risk. Lifestyle patterns also begin early and impact CVD risk. In addition, obesity and other CVD risk factors tend to persist over time. However, whether childhood obesity causes adult CVD directly, or does so by persisting as adult obesity, or both, is less clear. Regardless, sufficient data exist to warrant early implementation of both obesity prevention and treatment in youth and adults. In this Review, we examine the evidence supporting the impact of childhood obesity on adult obesity, surrogate markers of CVD, components of the metabolic syndrome, and the development of CVD. We also evaluate how obesity treatment strategies can improve risk factors and, ultimately, adverse clinical outcomes. PMID:21670745

    2009-03-01

    Type 2 diabetes mellitus (T2DM) in children and adolescents is an important Public Health problem against the backdrop of the epidemic of childhood obesity. The clinical presentation of T2DM in youth is heterogeneous from minimal symptomatology to diabetic ketoacidosis. The increasing rates of youth T2DM have paralleled the escalating rates of obesity, which is the major risk factor impacting insulin sensitivity. Additional risk factors include minority race, family history of diabetes mellitus, maternal diabetes during pregnancy, pubertal age group and conditions associated with insulin resistance (IR) - such as polycystic ovary syndrome (PCOS). The pathophysiology of T2DM has been studied extensively in adults, and it is widely accepted that IR together with beta-cell failure are necessary for the development of clinical diabetes mellitus in adulthood. However, pathophysiologic studies in youth are limited and in some cases conflicting. Similar to adults, IR is a prerequisite, but beta-cell failure is necessary for progression from normal glucose tolerance to prediabetes and frank diabetes in youth. Even though rates of T2DM in youth are increasing, the overall prevalence remains low if compared with type 1 diabetes mellitus (T1DM). However, as youth with T1DM are becoming obese, the clinical distinction between T2DM and obese T1DM has become difficult, because of the overlapping clinical picture with evidence of islet cell autoimmunity in a significant proportion of clinically diagnosed youth with T2DM. The latter are most likely obese children with autoimmune T1DM who carry a misdiagnosis of T2DM. Further research is needed to probe the pathophysiological, immunological, and metabolic differences between these two groups in the hopes of assigning appropriate therapeutic regimens. These challenges combined with the evolving picture of youth T2DM and its future complications provide unending opportunities for acquisition of new knowledge in the field of childhood

    To prevent the intergenerational transfer of obesity and end the current epidemic, interventions are needed across the early life stages, from preconception to prenatal to infancy through the age of 2 years. The foundation for obesity is laid in early life by actions and interactions passed from parent to child that have long-lasting biologic and behavioral consequences. The purpose of this paper is to examine the best evidence about (a) factors in parents and offspring that promote obesity during the early life stages, (b) the social determinants and dimensions of obesity in early life, (c) promising and effective interventions for preventing obesity in early life, and (d) opportunities for future research into strategies to disrupt the intergenerational cycle of obesity that begins early in life. The pathway for halting the intergenerational obesity epidemic requires the discovery and development of evidence-based interventions that can act across multiple dimensions of influence on early life.

    To prevent the intergenerational transfer of obesity and end the current epidemic, interventions are needed across the early life stages, from preconception to prenatal to infancy through the age of 2 years. The foundation for obesity is laid in early life by actions and interactions passed from parent to child that have long-lasting biologic and behavioral consequences. The purpose of this paper is to examine the best evidence about (a) factors in parents and offspring that promote obesity during the early life stages, (b) the social determinants and dimensions of obesity in early life, (c) promising and effective interventions for preventing obesity in early life, and (d) opportunities for future research into strategies to disrupt the intergenerational cycle of obesity that begins early in life. The pathway for halting the intergenerational obesity epidemic requires the discovery and development of evidence-based interventions that can act across multiple dimensions of influence on early life.

    In the field of youth violence prevention, there has been increasing emphasis on "evidence based" programs and principles shown through scientific research as reaching their intended outcomes. Community mobilization and engagement play a critical role in many evidence-based programs and strategies, as it takes a concerted effort among a wide range of people within a community to alter behavior and maintain behavioral change. How do concerned individuals and groups within a community engage others within and outside of that community to effectively plan, develop and implement appropriate EB programs as well as evaluate the outcomes and impacts of locally developed programs yet to be proven? The authors discuss five elements essential for community engagement in evidence-based youth violence prevention based on their work in a university-community partnership through the Asian/Pacific Islander Youth Violence Prevention Center (API Center), a National Academic Center for Excellence on Youth Violence Prevention Center supported by the Centers for Disease Control and Prevention. They include: (a) aligning EBPs with a community's shared vision and values; (b) establishing an inclusive environment for the planning, implementation and evaluation of EBPs; (c) nurturing collaboration for increased effectiveness and efficacy of EBPs; (d) building adequate leadership and community capacity to develop and sustain EBPs; and (e) building a learning community for evaluation and self-reflection. The authors propose placing greater emphasis on "evaluative thinking" and organizational capacity for evaluation as we pursue evidence-based practices for youth violence prevention. This is especially important for ethnic groups for which an evidence base is not well established.

    To determine how the homeostasis model assessment of insulin resistance (HOMA-IR) is related to metabolic risk in a sample of overweight and obese Chilean youths accounting for Tanner stage. A cross-sectional study assessing 486 overweight and obese youths (aged 5-15 years) recruited from the University of Chile, Pediatric Obesity Clinic. We measured anthropometry, Tanner stage, HOMA-IR, and laboratory tests related to metabolic risk. HOMA-IR was categorized by quartile for children (Tanner stages I and II) and adolescents (Tanner stage III and above) from a normative Chilean sample. Children and adolescents with HOMA-IR in the highest quartile were likely to have higher body mass index (BMI) Z-scores, elevated waist circumference, systolic and diastolic blood pressure, and triglycerides and low high-density lipoprotein. HOMA-IR had good negative predictive value for characteristics of the metabolic syndrome (MetS; 0.82). In a multivariate regression model, BMI Z-score [odds ratio (OR) 1.5] and HOMA-IR (OR 3.3) predicted 22% of the variance for the MetS, with 36% of the explained variance attributed to HOMA-IR. In a large clinical sample of overweight and obese Chilean youths, HOMA-IR ≥ 75th percentile was significantly associated with the cluster of factors referred to as the MetS. We emphasize the importance of establishing percentiles for HOMA-IR based on a normative sample and taking Tanner stage into account. Although BMI is easy to assess and interpret with minimal costs in a clinical setting, adding HOMA-IR explains more of the variance in the MetS than BMI Z-score alone. © 2011 John Wiley & Sons A/S.

    Pediatric obesity is a worldwide health epidemic affecting both developed and developing countries. Mexico ranks second to the United States in rates of pediatric obesity. Obesity among youth has immediate and long-term consequences on physical and psychosocial development, including cardiovascular, respiratory, and health-related quality of life. Eventual amelioration of this epidemic will require change at the level of the family and community, along with policy initiatives to support healthier eating and activity habits. Evidence-based interventions for overweight/obese youth include family-based lifestyle programs that incorporate attention to diet quantity and quality, physical activity, sedentary behavior, and behavioral strategies to support change. While much of this research has been conducted in the United States, several recent studies suggest the efficacy of similar approaches for youth in Mexico. © The Author(s) 2016.

    To determine the prevalence of underweight, overweight and obesity in French youth from 2009 to 2013 and to determine if there are differences in weight categories according to socio-economic status. Cross-sectional study performed in different regions of France. Physical measures included weight, height and BMI. Underweight, overweight and obesity were defined according to age- and sex-specific BMI cut-off points from the International Obesity Task Force. France. Children and adolescents (n 9670; 4836 boys, 4834 girls) from the French national BOUGE Program between 2009 and 2013. The prevalence of obesity was higher in boys than girls (P0·05) and remained unchanged in boys (7·1-7·3 %) between 2009 and 2013. Overweight and obesity were higher in low socio-economic families (P<0·0001). Findings suggest that the prevalence of overweight was stable although high in French children and adolescents, while the prevalence of obesity increased significantly. Changes in underweight, although not significant, were high in girls and merit further attention. Improving public health interventions, especially in high-risk low socio-economic populations, may help to modify the behaviour that contributes to underweight, overweight and obesity in young boys and girls.

    The increasing prevalence of paediatric obesity and related metabolic complications has been mainly associated with lower aerobic fitness while less is known regarding potential musculoskeletal impairments. The purpose of the present systematic review was to report the evidence regarding muscular fitness in children and adolescents with obesity. A systematic article search was conducted between November 2014 and June 2015 using MEDLINE, EMBASE, CINAHL psycINFO, SPORTDiscus and SocINDEX. Articles published in English and reporting results on muscle strength and muscular fitness in children and adolescents aged 6 to 18 years were eligible. Of 548 identified titles, 36 studies were included for analyses. While laboratory-based studies described higher absolute muscular fitness in youth with obesity compared with their lean peers, these differences are negated when corrected for body weight and lean mass, then supporting field-based investigations. All interventional studies reviewed led to improved muscular fitness in youth with obesity. Children and adolescents with obesity display impaired muscular fitness compared to healthy-weight peers, which seems mainly due to factors such as excessive body weight and increased inertia of the body. Our analysis also points out the lack of information regarding the role of age, maturation or sex in the current literature and reveals that routinely used field tests analysing overall daily muscular fitness in children with obesity provide satisfactory results when compared to laboratory-based data.

    Urban sprawl is a potential environmental influence on youth overweight/obesity. However, little is known about the association between urban sprawl and behaviours that influence obesity such as active transportation and physical activity. The study population consisted of 7,017 respondents aged 12 to 19 to the 2007/2008 Canadian Community Health Survey, living in Canada's 33 census metropolitan areas (CMAs). Factor analysis was used to obtain an urban sprawl score for each CMA, incorporating dwelling density, percentage of single or detached dwelling units, and percentage of the population living in the urban core. Multi-level logistic regression examined whether urban sprawl was associated with frequent active transportation (30 or more minutes a day), moderate-to-vigorous physical activity (MVPA) (60 or more minutes a day), and overweight/obesity. Urban sprawl was associated with active transportation among 12- to 15-year-olds, with the relative odds of engaging in at least 30 minutes of active transportation per day increasing by 24% (95% CI: 10-39%) for each standard deviation (SD) increase in the urban sprawl score. For the entire sample aged 12 to 19, higher urban sprawl was associated with MVPA (odds ratio per SD increase = 1.10, 95% CI: 1.01-1.20), but not with overweight/obesity (odds ratio per SD increase = 1.06, 95% CI: 0.94-1.18). Urban sprawl was associated with active transportation and MVPA in Canadian youth, although in the opposite direction to what has been reported in the literature for adults.

    Mexico is a developing country with one of the highest youth obesity rates worldwide; >34% of children and adolescents between 5 and 19 years of age are overweight or obese. The current review seeks to compile, describe, and analyze dietary conditions, physical activity, socioeconomic status, and cultural factors that create and exacerbate an obesogenic environment among Mexican youth. A narrative review was performed using PubMed and the Cochrane Library databases, as well as grey literature data from the Mexican government, academics, and statistical reports from nongovernmental organizations, included in electronic formats. The recent socioeconomic and nutritional transition has resulted in reduced healthy meal options at public schools, high rates of sedentary lifestyles among adolescents, lack of open spaces and playgrounds, socioeconomic deprivation, false or misunderstood sociocultural traditional beliefs, misconceptions about health, a high percentage of overweight or obese adults, and low rates of maternal breastfeeding. Some of the factors identified are exacerbating the obesity problem in this population. Current evidence also shows that more policies and health programs are needed for prevention of childhood and adolescent obesity. Mexico presents alarming obesity levels, which need to be curtailed and urgently reversed. The present narrative review presents an overview of dietary, physical activity, societal and cultural preconceptions that are potentially modifiable obesity-promoting factors in Mexican youth. Measures to control these factors need to be implemented in all similar developing countries by governments, policy makers, stakeholders, and health care professionals to tackle obesity in children and young people.

    Context: The use of social marketing to modify lifestyle choices could be helpful in reducing youth obesity. Some or all of the 8 domains of the National Social Marketing Centre’s social marketing benchmark criteria (SMBC) are often used but not always defined in intervention studies. Objective: The aim of this review is to assess the effectiveness of European school-based interventions to prevent obesity relative to the inclusion of SMBC domains in the intervention. Data Sources: The PubMed, Cochrane, and ERIC databases were used. Study Selection: Nonrandomized and randomized controlled trials conducted from 1990 to April 2014 in participants aged 5 to 17 years were included. Data Extraction: After the study selection, the 8 domains of the SMBC were assessed in each included study. Results: Thirty-eight publications were included in the systematic review. For the meta-analysis, randomized controlled trials (RCTs) reporting body mass index or prevalence of overweight and obesity were considered. Eighteen RCTs with a total of 8681 participants included at least 5 SMBC. The meta-analysis showed a small standardized mean difference in body mass index of −0.25 (95%CI, −0.45 to −0.04) and a prevalence of overweight and obesity odds ratio of 0.72 (95%CI, 0.5–0.97). Conclusion: Current evidence indicates that the inclusion of at least 5 SMBC domains in school-based interventions could benefit efforts to prevent obesity in young people.

    Obese youth demonstrate the same obesity-associated morbidities observed in obese adults, including poor cardiorespiratory fitness, poor quality of life, and reports of musculoskeletal pain. The purposes of this study were to compare the prevalence of cardiovascular risk factors and evaluate the odds of metabolic syndrome in obese youth based on measures of cardiorespiratory fitness, quality of life, and pain. A medical chart review of 183 obese youth in a medical weight management program was conducted. Measures of cardiovascular risk and metabolic syndrome were recorded. Groups were categorized based on Progressive Aerobic Cardiovascular Endurance Run (PACER) score, Pediatric Quality of Life (PedsQL)-Physical Function score, PedsQL-Psychosocial Health score, and reports of musculoskeletal pain. Statistical analysis included independent t-tests, Mann-Whitney U-test, chi-squared test, and logistic regression. Thirty-three percent of the entire sample had C-reactive protein (CRP) levels >3.0 mg/dL and 30% were categorized as having metabolic syndrome. Patients with lower PACER scores demonstrated a greater prevalence of CRP levels >3.0 mg/dL versus those with higher PACER scores (45% vs. 12%; P=0.01). There were no other differences in the prevalence of cardiovascular risk factors or metabolic syndrome when categorized by PACER, PedsQL, or pain. Those with CRP levels >3.0 mg/dL demonstrated increased odds of metabolic syndrome-[odds (95% confidence interval, CI): 4.93 (1.24-19.61); P=0.02]. Overall, results do not show differences in cardiovascular risk in obese youth when categorized by PACER, PedsQL, or reports of MSK pain. Elevated CRP may be a useful predictor of metabolic syndrome in obese youth and warrants further investigation.

    Dietary determinants of hepatic steatosis, an important precursor for nonalcoholic fatty liver disease, are undefined. We explored the roles of sugar and fat intake as determinants of hepatic steatosis and visceral obesity in overweight adolescents at risk of type 2 diabetes. This was a cross-sectional study of dietary patterns and adipose tissue distribution in 74 overweight adolescents (aged: 15.4 ± 1.8 y; body mass index z score: 2.2 ± 0.4). Main outcome measures were hepatic steatosis (≥5.5% fat:water) measured by magnetic resonance spectroscopy and visceral obesity (visceral-to-subcutaneous adipose tissue ratio ≥0.25) measured by magnetic resonance imaging. Main exposure variables were dietary intake and habits assessed by the Harvard Youth Adolescent Food Frequency Questionnaire. Hepatic steatosis and visceral obesity were evident in 43% and 44% of the sample, respectively. Fried food consumption was more common in adolescents with hepatic steatosis than in adolescents without hepatic steatosis (41% compared with 18%; P = 0.04). Total fat intake (β = 0.51, P = 0.03) and the consumption of >35% of daily energy intake from fat (OR: 11.8; 95% CI: 1.6, 86.6; P = 0.02) were both positively associated with hepatic steatosis. Available carbohydrate (β = 0.54, P = 0.02) and the frequent consumption of soda were positively associated with visceral obesity (OR: 6.4; 95% CI: 1.2, 34.0; P = 0.03). Daily fiber intake was associated with reduced odds of visceral obesity (OR: 0.82; 95% CI: 0.68, 0.98; P = 0.02) but not hepatic steatosis. Hepatic steatosis is associated with a greater intake of fat and fried foods, whereas visceral obesity is associated with increased consumption of sugar and reduced consumption of fiber in overweight and obese adolescents at risk of type 2 diabetes.

    We explored family processes in adolescence that may influence the likelihood of obesity in early adulthood using a randomized trial of a family-based intervention (the Family CheckUp, or FCU). The FCU has been shown to reduce escalations in antisocial behavior and depression in adolescence by supporting positive family management practices, but no research has examined the mechanisms by which the FCU could influence health-related attitudes and behaviors linked to obesity. Participants were 998 adolescents (n = 526 male; n = 423 European American; M age 12.21 yrs) and their families, recruited in 6th grade from 3 middle schools in the Pacific Northwest. We used structural equation modeling (SEM) and an Intent-To-Treat (ITT) design to evaluate the direct and indirect effects of the FCU on parent–youth relationship quality (ages 12–15), healthy lifestyle behaviors, eating attitudes, depressive symptoms (all measured at age 17), and obesity (age 22). We found that the FCU led to greater parent–youth relationship quality, which predicted enhanced health-related behaviors, reduced maladaptive eating attitudes, and reduced depression. In turn, reduced maladaptive eating attitudes predicted reduced odds of obesity. The indirect effect of the FCU on obesity by way of parent–youth relationship quality and eating attitudes was significant. Our findings illustrate how family processes may influence adolescent health and suggest that family functioning may be an additional factor to consider when developing intervention programs for obesity.

    Objectives. We describe how scientific evidence about obesity has been used in Minnesota legislative materials to understand how research evidence might more effectively be translated into policymaking. Methods. We selected 13 obesity-related bills introduced from 2007 to 2011 in Minnesota. Using state archives, we collected all legislative committee meeting materials and floor testimony related to each bill. We used a coding instrument to systematically analyze the content of a sample of 109 materials for their use of research evidence and non–research-based information. Results. Research evidence was mentioned in 41% of all legislative materials. Evidence was often used to describe the prevalence or consequences of obesity or policy impacts but not to describe health disparities. In 45% of materials that cited evidence, no source of evidence was indicated. By contrast, 92% of materials presented non–research-based information, such as expert beliefs, constituent opinion, political principles, and anecdotes. Conclusions. Despite an abundance of available research evidence on obesity, less than half of legislative materials cited any such evidence in discussions around obesity-related bills under consideration in Minnesota.

    Childhood obesity is a growing concern, and while progress has been made to understand the association between multiple biological factors (i.e., genetics, nutrition, exercise etc.), little is known about the relationship between mental health and childhood obesity. In this paper, we offer a review of current evidence about the association between mental health and childhood obesity. A systematic literature search of peer-reviewed, English-language studies published between January 2000 and January 2011 was undertaken and resulted in 759 unique records, of which 345 full-text articles were retrieved and 131 articles were included. A theoretical model is proposed to organize the paper and reflect the current state of the literature and includes psychological factors (i.e., depression and anxiety, self-esteem, body dissatisfaction, eating disordered symptoms, and emotional problems); psychosocial mediating variables (i.e., weight-based teasing and concern about weight and shape), and wellness factors (i.e., quality of life and resiliency/protective factors). We conclude with a number of recommendations to support the creation of solutions to the rise in childhood obesity rates that do not further marginalize overweight and obese children and youth and that can potentially improve the well-being of all children and youth regardless of their weight status.

    The epidemic of overweight/obesity affects youth with type 1 diabetes mellitus (T1DM) and their families. In youth with T1DM and their parents, we examined weight status with reported and expected energy intake and with youth hemoglobin A1c (HbA1c). In 243 youth (48% female, 13 ± 3 years) and their parents (84% female, 45 ± 6 years), we assessed body mass index (BMI), prevalence of overweight/obesity, reported energy intake (REI), and youth glycemic control (HbA1c). The REI was compared with predicted daily energy requirements (DER; based on age, weight, sex, and physical activity). Youth had diabetes duration of 6.3 ± 3.4 years and HbA1c of 8.5% ± 1.3%; 69% used insulin pump therapy. Overweight and obesity affected 23% and 11% of youth and 30% and 24% of parents, respectively. Youth and parent BMI (r = 0.38; p < .001) and weight status (overweight/obese; p < .001) were significantly associated. The ratio of REI:DER was significantly lower in overweight/obese compared with underweight/normal weight parents (1.0 ± 0.4 versus 1.2 ± 0.5; p = .001) but did not differ among youth by weight status. Both youth and parent BMI were positively correlated with youth HbA1c (r = 0.14, p = .02; r = 0.16, p = .01, respectively). Hemoglobin A1c tended to be higher in obese than in overweight and normal weight youth (mean ± standard deviation [SD] 8.4 ± 1.4, 8.4 ± 1.3, and 8.8 ± 1.0, respectively; p = .06) and was significantly higher in youth whose parents were obese versus overweight or underweight/normal weight (mean ± SD 8.2 ± 1.2, 8.5 ± 1.4, and 8.9 ± 1.5, respectively; p < .001). Similar to the general population, overweight and obesity are prevalent among families of youth with T1DM. Weight status appears to influence self-REI in parents and glycemic control in youth with T1DM, suggesting the need for family-based dietary interventions. © 2012 Diabetes Technology Society.

    Rates of overweight in youth have reached epidemic proportions and are associated with adverse health outcomes. Family-based programs have been widely used to treat overweight in youth. However, few programs incorporate a theoretical framework for studying a family systems approach in relation to youth health behavior change. Therefore, this review provides a family systems theory framework for evaluating family-level variables in weight loss, physical activity, and dietary approaches in youth. Studies were reviewed and effect sizes were calculated for interventions that manipulated the family system, including components that targeted parenting styles, parenting skills, or family functioning, or which had novel approaches for including the family. Twenty-one weight loss interventions were identified, and 25 interventions related to physical activity and/or diet were identified. Overall, family-based treatment programs that incorporated training for authoritative parenting styles, parenting skills, or child management, and family functioning had positive effects on youth weight loss. Programs to improve physical activity and dietary behaviors that targeted the family system also demonstrated improvements in youth health behaviors; however, direct effects of parent-targeted programming is not clear. Both treatment and prevention programs would benefit from evaluating family functioning and parenting styles as possible mediators of intervention outcomes. Recommendations are provided to guide the development of future family-based obesity prevention and treatment programs for youth. PMID:20689989

    To evaluate the claim that the tobacco industry does not market its products to youth. The data for this study come from tobacco industry documents collected from the tobacco industry's document websites, presently linked at http://www.tobaccoarchives.com. The websites were searched using "request for production" (RFP) codes, specified keyword searches, and serendipitous terms identified in document citations found with RFP and keyword searches. Industry documents show that the cigarette manufacturers carefully monitored the smoking habits of teenagers over the past several decades. Candid quotes from industry executives refer to youth as a source of sales and as fundamental to the survival of the tobacco industry. The documents reveal that the features of cigarette brands (that is, use of filters, low tar, bland taste, etc), packaging (that is, size, colour and design), and advertising (that is, media placements and themes and imagery) were developed specifically to appeal to new smokers (that is, teenagers). Evidence also indicates that relevant youth oriented marketing documents may have been destroyed and that the language used in some of the more recent documents may have been sanitised to cover up efforts to market to youth. The tobacco industry's internal documents reveal an undeniable interest in marketing cigarettes to underage smokers. The industry's marketing approaches run counter to and predicate methods for tobacco prevention: (1) keep the price of the product high; (2) keep product placements and advertising away from schools and other areas with a high volume of youth traffic; (3) make cigarette advertising (that is, themes and visual images) unappealing to youth; (4) make product packaging unappealing to youth; and (5) design the product so it is not easy to inhale.

    Background Mexico is a developing country with one of the highest youth obesity rates worldwide; >34% of children and adolescents between 5 and 19 years of age are overweight or obese. Objectives The current review seeks to compile, describe, and analyze dietary conditions, physical activity, socioeconomic status, and cultural factors that create and exacerbate an obesogenic environment among Mexican youth. Design A narrative review was performed using PubMed and the Cochrane Library databases, as well as grey literature data from the Mexican government, academics, and statistical reports from nongovernmental organizations, included in electronic formats. Results The recent socioeconomic and nutritional transition has resulted in reduced healthy meal options at public schools, high rates of sedentary lifestyles among adolescents, lack of open spaces and playgrounds, socioeconomic deprivation, false or misunderstood sociocultural traditional beliefs, misconceptions about health, a high percentage of overweight or obese adults, and low rates of maternal breastfeeding. Some of the factors identified are exacerbating the obesity problem in this population. Current evidence also shows that more policies and health programs are needed for prevention of childhood and adolescent obesity. Mexico presents alarming obesity levels, which need to be curtailed and urgently reversed. Conclusions The present narrative review presents an overview of dietary, physical activity, societal and cultural preconceptions that are potentially modifiable obesity-promoting factors in Mexican youth. Measures to control these factors need to be implemented in all similar developing countries by governments, policy makers, stakeholders, and health care professionals to tackle obesity in children and young people.

    Evidence shows a high incidence of insulin resistance, inflammation and dyslipidemia in adult obesity. The aim of this study was to assess the relevance of inflammatory markers, circulating lipids, and insulin sensitivity in overweight/obese children. We enrolled 45 male children (aged 6 to 13 years, lean control = 16, obese = 19, overweight = 10) in this study. The plasma total cholesterol, HDL cholesterol, triglyceride, glucose and insulin levels, the circulating levels of inflammatory factors, such as TNF-α, IL-6, and MCP-1, and the high-sensitive CRP level were determined using quantitative colorimetric sandwich ELISA kits. Compared with the lean control subjects, the obese subjects had obvious insulin resistance, abnormal lipid profiles, and low-grade inflammation. The overweight subjects only exhibited significant insulin resistance and low-grade inflammation. Both TNF-α and leptin levels were higher in the overweight/obese subjects. A concurrent correlation analysis showed that body mass index (BMI) percentile and fasting insulin were positively correlated with insulin resistance, lipid profiles, and inflammatory markers but negatively correlated with adiponectin. A factor analysis identified three domains that explained 74.08% of the total variance among the obese children (factor 1: lipid, 46.05%; factor 2: obesity-inflammation, 15.38%; factor 3: insulin sensitivity domains, 12.65%). Our findings suggest that lipid, obesity-inflammation, and insulin sensitivity domains predominantly exist among obese children. These factors might be applied to predict the outcomes of cardiovascular diseases in the future.

    The use of social marketing to modify lifestyle choices could be helpful in reducing youth obesity. Some or all of the 8 domains of the National Social Marketing Centre's social marketing benchmark criteria (SMBC) are often used but not always defined in intervention studies. The aim of this review is to assess the effectiveness of European school-based interventions to prevent obesity relative to the inclusion of SMBC domains in the intervention. The PubMed, Cochrane, and ERIC databases were used. Nonrandomized and randomized controlled trials conducted from 1990 to April 2014 in participants aged 5 to 17 years were included. After the study selection, the 8 domains of the SMBC were assessed in each included study. Thirty-eight publications were included in the systematic review. For the meta-analysis, randomized controlled trials (RCTs) reporting body mass index or prevalence of overweight and obesity were considered. Eighteen RCTs with a total of 8681 participants included at least 5 SMBC. The meta-analysis showed a small standardized mean difference in body mass index of -0.25 (95%CI, -0.45 to -0.04) and a prevalence of overweight and obesity odds ratio of 0.72 (95%CI, 0.5-0.97). Current evidence indicates that the inclusion of at least 5 SMBC domains in school-based interventions could benefit efforts to prevent obesity in young people.

    The severity and frequency of childhood obesity has increased significantly over the past three to four decades. The health effects of increased body mass index as a child may significantly impact obese youth as they age. However, many of the long-term outcomes of childhood obesity have yet to be studied. This article examines the currently available longitudinal data evaluating the effects of childhood obesity on adult outcomes. Consequences of obesity include an increased risk of developing the metabolic syndrome, cardiovascular disease, type 2 diabetes and its associated retinal and renal complications, nonalcoholic fatty liver disease, obstructive sleep apnea, polycystic ovarian syndrome, infertility, asthma, orthopedic complications, psychiatric disease, and increased rates of cancer, among others. These disorders can start as early as childhood, and such early onset increases the likelihood of early morbidity and mortality. Being obese as a child also increases the likelihood of being obese as an adult, and obesity in adulthood also leads to obesity-related complications. This review outlines the evidence for childhood obesity as a predictor of adult obesity and obesity-related disorders, thereby emphasizing the importance of early intervention to prevent the onset of obesity in childhood.

    The optimal screening test for diabetes and prediabetes in obese youth is controversial. We examined whether glycosylated hemoglobin (HbA1c) or the oral glucose tolerance test (OGTT) is a better predictor of free-living glycemia as measured by continuous glucose monitoring (CGM). This was a cross-sectional study of youth 10-18 years old, body mass index (BMI) 85th percentile or greater, with diabetes risk factors. Participants (n = 118) with BMI 85th percentile or greater, not on medications for glucose management, were recruited from primary care and pediatric endocrinology clinics around Denver, Colorado. HbA1c, fasting plasma glucose, and 2-hour glucose were collected and all participants wore a blinded CGM for 72 hours. CGM outcomes were determined and descriptive statistics calculated. Performance characteristics at current American Diabetes Association cutpoints were compared with CGM outcomes. CGM data were successfully collected on 98 obese youth. Those with prediabetes had significantly higher average glucose, area under the curve (AUC), peak glucose, and time greater than 120 and greater than 140 mg/dL (P < .01) on CGM than youth with normal HbA1c or OGTT. HbA1c had a greater magnitude of correlation to CGM average glucose, AUC, and minimum glucose; 2-hour glucose had a greater magnitude of correlation to CGM SD, peak glucose, and time greater than 140 and greater than 200 mg/dL. However, there were no overall differences in the strength comparisons between 2-hour glucose and HbA1c correlations to CGM outcomes. In obese youth, HbA1c and 2-hour glucose performed equally well at predicting free-living glycemia on CGM, suggesting that both are valid tests for dysglycemia screening.

    Obesity is a topic on which many views are strongly held in the absence of scientific evidence to support those views, and some views are strongly held despite evidence to contradict those views. We refer to the former as “presumptions” and the latter as “myths”. Here we present nine myths and ten presumptions surrounding the effects of rapid weight loss; setting realistic goals in weight loss therapy; stage of change or readiness to lose weight; physical education classes; breast-feeding; daily self-weighing; genetic contribution to obesity; the “Freshman 15”; food deserts; regularly eating (versus skipping) breakfast; eating close to bedtime; eating more fruits and vegetables; weight cycling (i.e. yo-yo dieting); snacking; built environment; reducing screen time in childhood obesity; portion size; participation in family mealtime; and drinking water as a means of weight-loss. For each of these, we describe the belief and present evidence that the belief is widely held or stated, reasons to support the conjecture that the belief might be true, evidence to directly support or refute the belief, and findings from randomized controlled trials, if available. We conclude with a discussion of the implications of these determinations, conjecture on why so many myths and presumptions exist, and suggestions for limiting the spread of these and other unsubstantiated beliefs about obesity domain.

    This article reviews research on evidence-based treatments (EBTs) for ethnic minority youth using criteria from Chambless et al. (1998), Chambless et al. (1996), and Chambless and Hollon (1998). Although no well-established treatments were identified, probably efficacious or possibly efficacious treatments were found for ethnic minority youth with anxiety-related problems, attention-deficit/hyperactivity disorder, depression, conduct problems, substance use problems, trauma-related syndromes, and other clinical problems. In addition, all studies met either Nathan and Gorman's (2002) Type 1 or Type 2 methodological criteria. A brief meta-analysis showed overall treatment effects of medium magnitude (d = .44). Effects were larger when EBTs were compared to no treatment (d = .58) or psychological placebos (d = .51) versus treatment as usual (d = .22). Youth ethnicity (African American, Latino, mixed/other minority), problem type, clinical severity, diagnostic status, and culture-responsive treatment status did not moderate treatment outcome. Most studies had low statistical power and poor representation of less acculturated youth. Few tests of cultural adaptation effects have been conducted in the literature and culturally validated outcome measures are mostly lacking. Recommendations for clinical practice and future research directions are provided. PMID:18444061

    Previous studies have found that obesity could influence academic performance. The aim of this study was to systematically review the scientific evidence on the association between obesity and academic performance in school children. A systematic review of English articles was undertaken by using databases PubMed/Medline, ERIC, LILACS, SciELO and Web of Science. Cross-sectional and longitudinal studies examining the association between obesity and academic performance in children and adolescents, published between January 1990 and December 2016, were included. Risk of bias was assessed by using Strengthening the Reporting of Observational Studies in Epidemiology. Thirty-four studies (23 cross-sectional and 11 longitudinal) matched all inclusion criteria and were included. Seven studies were classified as low risk of bias, 23 as medium risk and four as high risk. After controlling for covariates such as socio-economic status, parental education and physical activity, the association between obesity and academic performance becomes uncertain for most of the studies (55.9%). Therefore, at present, there is insufficient evidence to support a direct link between obesity and poor academic performance in school age children. In order to clarify this issue, we need more longitudinal studies with adequate sample sizes and that control for potential confounders. © 2017 World Obesity Federation.

  9. Obesity in Children and the 'Myth of Psychological Maladjustment': Self-Esteem in the Spotlight.

    PubMed

    Hill, Andrew J

    2017-03-01

    There are contrasting views regarding the psychological well-being of children with obesity. Responding to limitations of existing evidence, Jane Wardle in 2005 argued for a 'myth of psychological maladjustment'. This review looks again at self-esteem. The different characterisations of self-esteem each offer value. Global self-esteem is reduced in nearly all studies of youth with obesity. Dimensional self-esteem reveals physical appearance, athletic and social competence as the most affected areas, confirmed by research that has operationalised low self-competence. Children with obesity are also more likely to be victimised by their peers, generally and for their fatness. Victims who bully others appear to preserve some aspects of self-esteem. A relatively small proportion of youth with obesity has low self-esteem, but those with severe and persistent obesity are especially compromised. Weight loss is only weakly associated with improved self-competence suggesting the value of resilience and asset approaches to improving well-being.

    Obesity may lead to depression or be one of its consequences. We reviewed population-based studies in order to, first, identify the most commonly used research methods, and, second, to evaluate the strength of evidence for prospective associations among obesity and depression. We examined 25 studies, of which 10 tested 'obesity-to-depression' pathways, and 15 tested 'depression-to-obesity' pathways. Descriptive statistics summarized the frequency with which various measurements, designs and data analytic strategies were used. We tallied the number of studies that reported any vs. no statistically significant associations, and report on effect sizes, identified moderating variables within reports, and sought common findings across studies. Results indicated considerable methodological heterogeneity in the literature. Depression was assessed by clinical interview in 44% of studies, weight and height were directly measured in 32%, and only 12% used both. In total, 80% of the studies reported significant obesity-to-depression associations, with odds ratios generally in the range of 1.0 to 2.0, while only 53% of the studies reported significant depression-to-obesity associations. Sex was a common moderating variable. Thus, there was good evidence that obesity is prospectively associated with increased depression, with less consistent evidence that depression leads to obesity.

    Youth with type 1 diabetes (T1D) are at risk for weight gain due to the epidemic of childhood overweight/obesity and common use of intensive insulin therapy; the latter resulted in weight gain in the Diabetes Control and Complications Trial. To assess overweight/obesity prevalence and intensive insulin therapy use in youth with T1D over a decade and identify factors associated with weight status and glycemic control. We obtained cross-sectional data from four unique cohorts (1999, 2002, 2006, and 2009). Youth (N = 507, 49% male) were 8-16 yr old with T1D duration ≥6 months, A1c 6.0-12.0% (42-108 mmol/mol), and daily insulin dose ≥0.5 U/kg. Across cohorts, age, body mass index (BMI) percentile, and A1c ranged from 12.0 ± 2.2 to 12.8 ± 2.3 yr, 70 ± 22 to 72 ± 21, and 8.3 ± 1.0 (67 ± 11) to 8.5 ± 1.1% (69 ± 12 mmol/mol), respectively. Intensive insulin therapy use increased from 52 to 97% (p < 0.001) between 1999 and 2009. However, prevalence of overweight/obesity remained similar, 27% (1999), 36% (2002), 33% (2006), and 31% (2009) (p = 0.54), as did z-BMI. In multivariate analysis, higher A1c was related to higher insulin dose (p < 0.01), less frequent blood glucose monitoring (p < 0.001), and non-white race (p < 0.001); A1c was not related to z-BMI, intensive insulin therapy, or cohort. z-BMI was related to insulin dose (p < 0.005) but not intensive insulin therapy or cohort. Despite near-universal implementation of intensive insulin therapy, overweight/obesity prevalence in youth with T1D remained stable over a decade, similar to the general pediatric population. However, A1c remained suboptimal, underscoring the need to optimize T1D treatment to reduce future complication risk. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    This study examines the prevalence of overweight and obesity and a panel of potential determinants among French youths and adults with an intellectual disability (ID). The sample used consisted of 1120 youths and adults with an ID, from 5 to 28 years old, attending a French special education school. The results indicated that 19.8% of the participants with an ID are classified as overweight and 8.6% as obese. Multivariate logistic regression analyses revealed that there are nearly three times more girls/women classified as overweight than boys/men. Additionally, they showed that there are nearly two times more participants from southern France classified as overweight than from northern France, and that the risk of being classified as overweight significantly increases with seniority in the school. Next, the interaction effects observed indicated first that there are nearly two times more boys/men on psychotropic medication classified as overweight than boys/men not on psychotropic medication. Second, they revealed that the odds of being classified as overweight for boys/men not on psychotropic medication are 47% lower than for girls/women not on psychotropic medication. Third, they indicated that there are nearly two times more boys/men from southern France classified as obese than boys/men from northern France. Fourth, they showed that the odds of being classified as obese for boys/men from northern France are 52% lower than for girls/women from northern France. In conclusion, these results should be viewed as preliminary and need to be replicated since, to our knowledge, this study is the first one to examine this topic while simultaneously controlling for all of the potential determinants and relying on a sample of youths and adults.

    2017-05-01

    As a consequence of the global rise in the prevalence of adolescent obesity, an unprecedented phenomenon of type 2 diabetes has emerged in pediatrics. At the heart of the development of type 2 diabetes lies a key metabolic derangement: insulin resistance (IR). Despite the widespread occurrence of IR affecting an unmeasurable number of youths worldwide, its pathogenesis remains elusive. IR in obese youth is a complex phenomenon that defies explanation by a single pathway. In this review we first describe recent data on the prevalence, severity, and racial/ethnic differences in pediatric obesity. We follow by elucidating the initiating events associated with the onset of IR, and describe a distinct "endophenotype" in obese adolescents characterized by a thin superficial layer of abdominal subcutaneous adipose tissue, increased visceral adipose tissue, marked IR, dyslipidemia, and fatty liver. Further, we provide evidence for the cellular and molecular mechanisms associated with this peculiar endophenotype and its relations to IR in the obese adolescent. Copyright © 2017 AGA Institute.

    2014-01-01

    This study sampled 2872 obesity-relevant comments from three years of interest from a multi-topic online message board. An inductive thematic analysis was conducted and three themes were evident: reactions and responses to obesity and obese bodies, diminished status of overweight/obese persons, and narrative resistance to an overweight/obese identity. Obesity stigma was pervasive and the discussion of the issue revealed it to be highly acceptable. Consistent with previous research, dominant representations of obese persons as lazy and unintelligent with poor self-control were evident. The analysis provided valuable insight into experiences of explicit stigma, the social and psychological repercussions of overt stigma and norms regarding the perception of obese bodies. There was a prevailing notion that the opinions and insights of overweight and obese persons on the issue of weight were not credible and were perceived as biased. Furthermore, individuals sought to distance themselves from the undesirable labels of 'overweight' and 'obese' by enacting narrative resistance to negotiate the social meaning of excess weight and endeavouring to place themselves on the 'safe' side of this boundary. These results highlight the pervasive nature of weight stigma and the social acceptability of such attitudes and beliefs. Furthermore, it highlights the richness of data that may be obtained by examining social media interactions as a window into the naturally-occurring discourse on obesity and stigma.

    Introduction: Indigenous children are twice as likely to be classified as obese and three times as likely to experience household food insecurity when compared with non- Indigenous Canadian children. The purpose of this study was to explore the relationship between food insecurity and weight status among Métis and off-reserve First Nations children and youth across Canada. Methods: We obtained data on children and youth aged 6 to 17 years (n = 6900) from the 2012 Aboriginal Peoples Survey. We tested bivariate relationships using Pearson chisquare tests and used nested binary logistic regressions to examine the food insecurity− weight status relationship, after controlling for geography, household and school characteristics and cultural factors. Results: Approximately 22% of Métis and First Nations children and youth were overweight, and 15% were classified as obese. Over 80% of the sample was reported as food secure, 9% experienced low food security and 7% were severely food insecure. Off-reserve Indigenous children and youth from households with very low food security were at higher risk of overweight or obese status; however, this excess risk was not independent of household socioeconomic status, and was reduced by controlling for household income, adjusted for household size. Negative school environment was also a significant predictor of obesity risk, independent of demographic, household and geographic factors. Conclusion: Both food insecurity and obesity were prevalent among the Indigenous groups studied, and our results suggest that a large proportion of children and youth who are food insecure are also overweight or obese. This study reinforces the importance of including social determinants of health, such as income, school environment and geography, in programs or policies targeting child obesity. PMID:28273035

Both food insecurity and obesity were prevalent among the Indigenous groups studied, and our results suggest that a large proportion of children and youth who are food insecure are also overweight or obese. This study reinforces the importance of including social determinants of health, such as income, school environment and geography, in programs or policies targeting child obesity.

    Both substance use and obesity are prevalent among youth. As youth age, substance use rates increase and over the past three decades, obesity rates among youth have tripled. While these two factors have both short- and long-term health impacts, little research has explored how substance use and obesity among youth may be related. This study…

    Obesity is associated with increased risk for chronic diseases, and affects both developed and developing nations. Yogurt is a nutrient-dense food that may benefit individuals with lactose intolerance, constipation and diarrheal diseases, hypertension, cardiovascular diseases, diabetes, and certain types of cancer. Emerging evidence suggests that yogurt consumption might also improve the health of obese individuals. Obesity is often accompanied by chronic, low-grade inflammation perpetuated by adipose tissue and the gut. In the gut, obesity-associated dysregulation of microbiota and impaired gut barrier function may increase endotoxin exposure. Intestinal barrier function can be compromised by pathogens, inflammatory cytokines, endocannabinoids, diet, exercise, and gastrointestinal peptides. Yogurt consumption may improve gut health and reduce chronic inflammation by enhancing innate and adaptive immune responses, intestinal barrier function, lipid profiles, and by regulating appetite. While this evidence suggests that yogurt consumption is beneficial for obese individuals, randomized-controlled trials are needed to further support this hypothesis.

    This paper describes the strategic efforts of six National Centers of Excellence in Youth Violence Prevention (YVPC), funded by the U.S. Centers for Disease Control and Prevention, to work in partnership with local communities to create comprehensive evidence-based program packages to prevent youth violence. Key components of a comprehensive evidence-based approach are defined and examples are provided from a variety of community settings (rural and urban) across the nation that illustrate attempts to respond to the unique needs of the communities while maintaining a focus on evidence-based programming and practices. At each YVPC site, the process of selecting prevention and intervention programs addressed the following factors: (1) community capacity, (2) researcher and community roles in selecting programs, (3) use of data in decision-making related to program selection, and (4) reach, resources, and dosage. We describe systemic barriers to these efforts, lessons learned, and opportunities for policy and practice. Although adopting an evidence-based comprehensive approach requires significant upfront resources and investment, it offers great potential for preventing youth violence and promoting the successful development of children, families and communities.

  3. [Scientific Evidence on Preventive Interventions in Childhood Obesity].

    Alba-Martín, Raquel

    The increasing prevalence of obesity or overweight at all ages, their associated morbidity and mortality associated, and the increased perception of the problem by the society have generated several hypotheses in response to the scientific and the international community. Investigate the preventive interventions in childhood obesity so far. Integrative review during the study period from April 2013 to November 2014. The MEDLINE international database was used, including PubMed, the Cochrane Library (Issue 4 2002), the national database Isooc (CSIC) national database, as well as the Internet. The review included health articles published in Spanish and English between 1990 and 2014 that focused on or included education, prevention, diagnostic, and treatment of obesity interventions. Of the 726 articles identified, 34 of most relevant (peer reviewed) were selected. It was noted that there is limited generisable evidence on interventions that could be implemented in Primary Care or referral services available, although numerous studies suggest that improvements in the overweight are possible. Despite the abundant literature and that many institutions place childhood obesity as one of the priorities of Public Health, we face the paradox that the evidence on cost-effectiveness of prevention interventions is sparse. Knowing these gaps in knowledge should lead to filling them with rigorous and well-designed studies. Copyright © 2016 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

    Obesity has reached epidemic proportions. Public health practitioners are distinctly positioned to promote the environmental changes essential to addressing obesity. The Centers for Disease Control and Prevention (CDC) and other entities provide evidence and technical assistance to support this work, yet little is known about how practitioners use evidence and support as they intervene to prevent obesity. The study's purpose was to describe how practitioners and CDC project officers characterized the obesity prevention task, where practitioners accessed support and evidence, and what approaches to support and evidence they found most useful. APPROACH OR DESIGN: Mixed-methods, cross-sectional interviews, and survey. State-level public health obesity prevention programs. Public health practitioners and CDC project officers. We conducted 10 in-depth interviews with public health practitioners (n = 7) and project officers (n = 3) followed by an online survey completed by 62 practitioners (50% response rate). We applied content analysis to interview data and descriptive statistics to survey data. Practitioners characterized obesity prevention as uncertain and complex, involving interdependence among actors, multiple levels of activity, an excess of information, and a paucity of evidence. Survey findings provide further detail on the types of evidence and support practitioners used and valued. We recommend approaches to tailoring evidence and support to the needs of practitioners working on obesity prevention and other complex health problems.

We searched Wanfang Data and PubMed databases for published studies on health hazards of childhood obesity in China during 2000-2015. From the evidence of the Chinese population studies, we know childhood obesity brings not only cardiovascular, endocrine and respiratory system health hazards, but also other health hazards to liver, moving skeleton, psychological behavior and cognition intelligence, et al. Only to understand the health hazards of childhood obesity, and put the key preventable period of chronic diseases forward to childhood, can pandemic of chronic diseases be controlled from the sources.

    Youth nutrition and their nutritional status are conditioned by many factors, some of the main ones being: economic, social, climatic, cultural, and psychological factors as well as nutritional knowledge. With the growing problem of overweight and obesity among children and young people, the incidence of the metabolic syndrome is also increasing. The aim of the study was to assess the impact of demographic, sociological and psychological factors on the incidence of obesity among 17-18-year-old adolescents from Wroclaw and vicinity as a major risk factor for the development of the metabolic syndrome. The study was conducted in three upper-secondary schools in Wroclaw, Poland. In the surveyed group (17-18 years old, n = 269) girls accounted for 59.5% and boys constituted 40.5%. Majority of young people were Wroclaw citizens (72.9%). Centile charts elaborated by the Children's Memorial Health Institute were adopted for the evaluation of anthropometric parameters. Evaluation of the impact of non-dietary factors on the manner of nutrition was carried out using own questionnaire. Based on the tests, abdominal obesity was determined among 34.5% of adolescents aged 17 years and among 65.5% of these aged 18 years. Obesity was more common in girls carrying genetic burden of the disease. Youth with the largest waist circumference most often declared to use slimming diets - 6.7%, and the lowest hunger sensation in stress - 3.4%. In addition, 30.5% of the adolescents with the smallest waist circumference and 11.5% with the largest waist circumference declared to be non-smoking. Occasional alcohol consumption was declared by 30.1% of young people with the smallest waist circumference, and 13.4% with the largest waist circumference. Youth with abdominal obesity significantly more likely than those with normal waist circumference applied slimming diets. Significant impact on the formation of abdominal obesity among girls had inherited disease burden.

    There is a paucity of recent data on Chinese childhood overweight and underweight prevalence especially since 2004. The purpose of this study was to examine trends in underweight and overweight/obesity ("overweight" hereafter) prevalence and energy balance-related behaviors of Chinese youth from 2004 to 2009. Data from the China Health and Nutrition Survey, 2004-2009 (N = 4,061 students aged 6-18 years), were analyzed. Trained health workers took anthropometric measures at the participant's house or at a local clinic following a reference protocol recommended by the World Health Organization. The international age- and sex-specific body mass index reference standard proposed by the International Obesity Task Force was used to define underweight and overweight children in this study. Among 6- to 11-year-old boys, underweight prevalence increased from 14.5% (2004) to 20.1% (2009, p = 0.068). Among 12- to 18-year-old boys, however, overweight prevalence increased from 7.5 to 12.6% (p = 0.034). From 2004 to 2009, after-school sedentary behavior increased from 2.3 to 3.4 h/day for 6- to 11-year-olds (p < 0.001) and from 2.2 to 3.1 h/day for 12- to 18-year-olds (p < 0.01). Meanwhile, the total energy intake decreased 7% for 6- to 11-year-olds (p < 0.05) and 10% for 12- to 18-year-olds (p < 0.01). Both underweight and overweight Chinese students are increasing, with underweight increases more pronounced in 6- to 11-year-olds and overweight increases more pronounced in 12- to 18-year-olds. Nationwide efficacious interventions are needed that improve the diet, decrease sedentary behavior, and encourage a healthy and realistic body image in Chinese youth.

    After nearly a decade of concern over the role of food and beverage marketing to youth in the childhood obesity epidemic, American children and adolescents - especially those from communities of color - are still immersed in advertising and marketing environments that primarily promote unhealthy foods and beverages. Despite some positive steps, the evidence shows that the food and beverage industry self-regulation alone is not likely to significantly reduce marketing of unhealthy foods and beverages to youth. A variety of research is needed to monitor industry marketing of unhealthy products to young people, and identify the most promising approaches to improve children's food marketing environments. The continued presence of unhealthy marketing toward children despite years of industry self-regulation suggests it is time for stronger action by policymakers to protect young people from harmful marketing practices.

  9. Oportunidades to reduce overweight and obesity in Mexico?

    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.

    We sought to assess the association between age and the prevalence of obesity among children with and without autism spectrum disorder (ASD) in the 2011-2012 National Survey of Children's Health. Analyses were restricted to 43,777 children, ages 10-17, with valid measures of parent-reported weight, height, and ASD status. Exploratory analyses describe the impact of sex, race/ethnicity, and household income on the relationship between age and obesity in ASD. Although the overall prevalence of obesity among children with ASD was significantly (p < 0.001) higher than among children without ASD (23.1% vs. 14.1%, 95% confidence interval for difference 3.6 to 14.4), child age significantly (p = 0.035) modified this difference. In a multivariable logistic regression analysis, adjusted for sex, race/ethnicity, and household income, the odds of obesity among children with ASD compared with children without ASD increased monotonically from ages 10 to 17 years. This pattern arose due to a consistently high prevalence of obesity among children with ASD and a decline in prevalence with advancing age among children without ASD. These findings were replicated using a propensity score analysis. Exploratory analyses suggested that the age-related change in obesity disparity between children with and without ASD may be further modified by sex, race/ethnicity, and household income. The patterns of prevalence observed with increasing age among children with and without ASD were unexpected. A better understanding of the etiological and maintenance factors for obesity in youth with ASD is needed to develop interventions tailored to the specific needs of these children.

    The Physical Activity Research Center developed a research agenda that addresses youth physical activity (PA) and healthy weight, and aligns with the Robert Wood Johnson Foundation's Culture of Health. This paper summarizes prioritized research studies with a focus on youth at higher risk for inactive lifestyles and childhood obesity in urban and rural communities. Systematic literature reviews, a survey, and discussions with practitioners and researchers provided guidance on research questions to build evidence and inform effective strategies to promote healthy weight and PA in youth across race, cultural, and economic groups. The research team developed a matrix of potential research questions, identified priority questions, and designed targeted studies to address some of the priority questions and inform advocacy efforts. The studies selected examine strategies advocating for activity-friendly communities, Play Streets, park use, and PA of youth in the summer. A broader set of research priorities for youth PA is proposed. Establishing the Physical Activity Research Center research agenda identified important initial and future research studies to promote and ensure healthy weight and healthy levels of PA for at-risk youth. Results will be disseminated with the goal of promoting equitable access to PA for youth.

    Population-level intervention is required to prevent cancer and other chronic diseases. It also promotes health for those living with established risk factors and illness. In this article, the authors describe a vision and approach for continuously improving population-level programs and policies within and beyond the health sector. The vision and approach are anchored in contemporary thinking about what is required to link evidence and action in the field of population and public health. The authors believe that, as a cancer prevention and control community, organizations and practitioners must be able to use the best available evidence to inform action and continually generate evidence that improves prevention policies and programs on an ongoing basis. These imperatives require leaders in policy, practice, and research fields to work together to jointly plan, conduct, and act on relevant evidence. The Propel Center and colleagues are implementing this approach in Youth Excel-a pan-Canadian initiative that brings together national and provincial organizations from health and education sectors and capitalizes on a history of collaboration. The objective of Youth Excel is to build sustainable capacity for knowledge development and exchange that can guide and redirect prevention efforts in a rapidly evolving social environment. This goal is to contribute to creating health-promoting environments and to accelerate progress in preventing cancer and other diseases among youth and young adults and in the wider population. Although prevention is the aim, health-promoting environments also can support health gains for individuals of all ages and with established illness. In addition, the approach Youth Excel is taking to link evidence and action may be applicable to early intervention and treatment components of cancer control. © 2011 American Cancer Society

    Point-of-sale (POS) tobacco advertising has been linked to youth smoking susceptibility and experimental smoking. However, there is limited evidence of the association between POS advertising bans and youth smoking participation. This study aims to examine how such bans are associated with current smoking, daily smoking, and regular smoking (≥ 1 cigarettes per day) participation among youth. one to two waves (primarily one wave) of the Global Youth Tobacco Survey were conducted in 130 countries between 2007 and 2011. These surveys were linked to the WHO "MPOWER" data using country and year identifiers to analyze the association between POS advertising bans (a dichotomous measure of the existence of such bans) and smoking participation in the past month. Weighted logistic regressions were employed to analyze this association while controlling for age, gender, parents' smoking status, 6 MPOWER policy scores, and GDP per capita. We find that in countries with POS advertising bans, current smoking (OR = 0.73, p ≤ 0.1), daily smoking (OR = 0.70, p ≤ 0.1), and regular smoking (OR = 0.75, p ≤ 0.05) participation in the past month is significantly lower, suggesting that POS promotion bans can potentially reduce youth smoking. This study provides evidence to support the implementation of POS promotion regulations by the US FDA and implementation of the WHO FCTC guidelines regarding restrictions on tobacco POS promotion.

Cross-sectional study of 7,759 children at age 7 years in the Avon Longitudinal Study of Parents and Children (ALSPAC) in the UK. In addition, longitudinal analyses were conducted between age 7 and 9 years. BMI at age 7 and 9 years was calculated from clinic-measured weight and height and standardised in reference to 1990 UK data. Dog ownership data were collected by carer questionnaire at various time points. After adjustment for confounding factors associated with dog ownership or obesity, there was no evidence of an association between obesity and dog ownership at 7 years OR = 1.18, 95% confidence interval = 0.88-1.59, p = 0.27), or dog ownership history. There was also no evidence for an effect of dog ownership on BMI change between 7 and 9 years, nor acquisition of a dog on the change in weight status of obese children between 7 and 9 years. This study provides no evidence for a protective effect of dog ownership on the development of childhood obesity. Further investigation is required to determine the impact of dog ownership on physical activity in overweight and obese children. Copyright © 2012 S. Karger GmbH, Freiburg

    Overweight and obesity are established risk factors for insulin resistance in youth. A number of behavioral recommendations have been publicized with the goal of improving glycemic control. However, there is limited information about whether meeting these behavioral recommendations actually reduces insulin resistance. 92 youths 11 - 16 years with BMI ≥ 85% underwent oral glucose tolerance testing. HOMA-IR and AUCInsulin/AUCGlucose were calculated as measures of insulin resistance. Dietary and physical activity (PA) measures were performed. Assessments included whether or not participants met recommended levels of diet, PA and sedentary behaviors.62% youths met criteria for insulin resistance. 82% (75/92) met at least one behavioral recommendation. Participants who met ≥ 1 dietary, sedentary, or PA recommendations had significantly reduced insulin resistance as compared with youth who did not. This relationship remained significant in multivariate modeling of insulin resistance adjusting for age, sex, and BMI. Even relatively minor behavior change may reduce insulin resistance in youth at risk for diabetes. Our findings support the relevance of current behavioral interventions for glycemic control.

    Engaging youth from racial and ethnic minority communities as leaders for change is a potential strategy to mobilize support for addressing childhood obesity, but there are limited curricula designed to help youth understand the complex influences on obesity. Our aim was to develop and pilot test a systems science curriculum to elicit rural African American youth perspectives on childhood obesity and enhance their understanding of and support for obesity prevention solutions. The curriculum was designed so it could be integrated with existing positive youth development curricula that help youth advocate for and implement identified solutions. We conducted four workshop sessions with youth that engaged them in systems learning activities such as guided systems diagramming activities. The participants ( n = 21) completed validated surveys presession and postsession that assessed their causal attributions of obesity and support for obesity prevention policies. The youths' perception that environmental factors cause obesity increased ( p < .05), and perceptions that individual behavior and biology cause obesity did not change. Their support for policies that addressed food access and food pricing significantly increased ( p < .05). The youths' system diagrams elucidated links between multilevel factors such as personal attitudes, social influence, and the built environment, which provides important information for designing synergistic solutions. The changes we observed in youths' perceptions of obesity and support for policy changes have important implications for youths' interest and willingness to advocate for social and environmental changes in their community. The strategies have a promising role in supporting community mobilization to address childhood obesity.

    Ethnic differences in lipid profiles exist in children and adolescents. This study assessed whether variations in lipid profiles present in overweight and obese youth were also observed in severely obese youth. Variations could explain the lower prevalence of the metabolic syndrome in certain ethnic groups at even severe levels of obesity. Data were obtained from the National Health and Nutrition Examination Survey for the years of 2001 through 2012. Subjects were divided into groups according to BMI classification. Normal weight was defined as a BMI less than the 85th percentile. Overweight was defined as a BMI between the 85th and 95th percentile. Class 1 obesity was defined as a BMI greater than the 95th percentile up to 120% of the 95th percentile. A BMI between 120% and 140% of the 95th percentile was defined as Class 2 obesity. Class 3 was defined as a BMI above 140% of the 95th percentile. Primary outcomes were mean total cholesterol, triglyceride, low-density lipoprotein, and high-density lipoprotein levels (HDL). The sample included 14,481 non-Hispanic black (NHB) (N = 4710), non-Hispanic white (N = 4910), and Mexican American (N = 4861) subjects. Across all BMI categories, the NHB group had significantly lower mean TG and higher mean HDL levels (p < 0.0001). Ethnic variations in lipid profiles were found in severely obese youth. These findings could explain the lower prevalence of the metabolic syndrome in NHB youth. Ethnic-specific guidelines are necessary for improved identification of those at risk at all levels of obesity.

    The Nigerian Report card on Physical Activity (PA) in Children and Youth was first developed in 2013 to inform practice and policy on healthy living and prevention of noncommunicable diseases among Nigerian children and youth. This article summarizes the results of the 2016 report card and provides updated evidence on the current situation in Nigeria. A comprehensive review of literature was undertaken by the Report Card Working Group. Grades were assigned to 10 PA indicators based on the criteria used for the 2013 edition. Grades assigned to the indicators were Overall PA, D; Active Play and Leisure, C; Active Transportation, B; Sedentary Behaviors (screen-based, F and nonscreen-based, D); Overweight and Obesity, A; PA in Schools, C-; Government/Nongovernment Organizations/Private Sector/Policy, B. The following indicators were graded as Incomplete: Organized Sport and PA, Community and Built Environment, and Family and Peers. The overall PA levels of Nigerian children and youth seemed to be declining compared with the 2013 Report card but with slight improvement in active play and leisure, and PA in school settings. A substantial number of Nigerian children and youth still have high sedentary behaviors, overweight and obesity. Efforts are needed to promote PA among them.

    There is emerging evidence suggesting the role of peripheral blood leukocytes in the pathogenesis of obesity and related diseases. However, few studies have taken a genome-wide approach to investigating gene expression profiles in peripheral leukocytes between obese and lean individuals with the consideration of obesity-related shifts in leukocyte types. We conducted this study in 95 African Americans (AAs) of both genders (age 14-20 years, 46 lean and 49 obese). Complete blood count with differential test (CBC) was performed in whole blood. Genome-wide gene expression analysis was obtained using the Illumina HumanHT-12 V4 Beadchip with RNA extracted from peripheral leukocytes. Out of the 95 participants, 64 had neutrophils stored. The validation study was based on real-time PCR with RNA extracted from purified neutrophils. CBC test suggested that, in males, obesity was associated with increased neutrophil percentage (P=0.03). Genome-wide gene expression analysis showed that, in males, the majority of the most differentially expressed genes were related to neutrophil activation. Validation of the gene expression levels of ELANE (neutrophil elastase) and MPO (myeloperoxidase) in purified neutrophils demonstrated that the expression of these two genes--important biomarkers of neutrophils activation--were significantly elevated in obese males (P=0.01 and P=0.02, respectively). The identification of increased neutrophil percentage and activation in obese AA males suggests that neutrophils have an essential role in the pathogenesis of obesity-related disease. Further functional and mechanistic studies on neutrophils may contribute to the development of novel intervention strategies reducing the burden associated with obesity-related health problems.

    OBJECTIVE We compared acylcarnitine (AcylCN) species, common amino acid and fat oxidation (FOX) byproducts, and plasma amino acids in normal weight (NW; n = 39), obese (OB; n = 64), and type 2 diabetic (n = 17) adolescents. RESEARCH DESIGN AND METHODS Fasting plasma was analyzed by tandem mass spectrometry, body composition by dual energy X-ray absorptiometry and computed tomography, and total-body lipolysis and substrate oxidation by [2H5]glycerol and indirect calorimetry, respectively. In vivo insulin sensitivity (IS) was assessed with a 3-h hyperinsulinemic-euglycemic clamp. RESULTS Long-chain AcylCNs (C18:2-CN to C14:0-CN) were similar among the three groups. Medium- to short-chain AcylCNs (except C8 and C10) were significantly lower in type 2 diabetes compared with NW, and when compared with OB, C2-, C6-, and C10-CN were lower. Amino acid concentrations were lower in type 2 diabetes compared with NW. Fasting lipolysis and FOX were higher in OB and type 2 diabetes compared with NW, and the negative association of FOX to C10:1 disappeared after controlling for adiposity, Tanner stage, and sex. IS was lower in OB and type 2 diabetes with positive associations between IS and arginine, histidine, and serine after adjusting for adiposity, Tanner stage, and sex. CONCLUSIONS These metabolomics results, together with the increased rates of in vivo FOX, are not supportive of defective fatty acid or amino acid metabolism in obesity and type 2 diabetes in youth. Such observations are consistent with early adaptive metabolic plasticity in youth, which over time—with continued obesity and aging—may become dysfunctional, as observed in adults. PMID:22266733

    Hispanic/Latinos have a high burden of cardiovascular disease (CVD) risk factors which may begin at young ages. We tested the association of CVD risk factors between Hispanic/Latino parents and their children. We conducted a cross-sectional study in the Hispanic Community Health Study/Study of Latinos Youth study. Girls (n = 674) and boys (n = 667) aged 8 to 16 years (mean age 12.1 years) and their parents (n = 942) had their CVD risk factors measured. CVD risk factors in parents were significantly positively associated with those same risk factors among youth. After adjustment for demographic characteristics, diet and physical activity, obese parents were significantly more likely to have youth who were overweight (odds ratios [ORs], 2.39; 95% confidence interval [CI], 1.20-4.76) or obese (OR, 6.16; 95% CI, 3.23-11.77) versus normal weight. Dyslipidemia among parents was associated with 1.98 higher odds of dyslipidemia among youth (95% CI, 1.37-2.87). Neither hypertension nor diabetes was associated with higher odds of high blood pressure or hyperglycemia (prediabetes or diabetes) in youth. Findings were consistent by sex and in younger (age <12 years) versus older (≥12 years) youth. Hispanic/Latino youth share patterns of obesity and CVD risk factors with their parents, which portends high risk for adult CVD. Copyright © 2017 Elsevier Inc. All rights reserved.

    Background: Point-of-sale (POS) tobacco advertising has been linked to youth smoking susceptibility and experimental smoking. However, there is limited evidence of the association between POS advertising bans and youth smoking participation. This study aims to examine how such bans are associated with current smoking, daily smoking, and regular smoking (≥1 cigarettes per day) participation among youth. Methods: one to two waves (primarily one wave) of the Global Youth Tobacco Survey were conducted in 130 countries between 2007 and 2011. These surveys were linked to the WHO “MPOWER” data using country and year identifiers to analyze the association between POS advertising bans (a dichotomous measure of the existence of such bans) and smoking participation in the past month. Weighted logistic regressions were employed to analyze this association while controlling for age, gender, parents’ smoking status, 6 MPOWER policy scores, and GDP per capita. Results and Conclusions: We find that in countries with POS advertising bans, current smoking (OR = 0.73, p ≤ 0.1), daily smoking (OR = 0.70, p ≤ 0.1), and regular smoking (OR = 0.75, p ≤ 0.05) participation in the past month is significantly lower, suggesting that POS promotion bans can potentially reduce youth smoking. This study provides evidence to support the implementation of POS promotion regulations by the US FDA and implementation of the WHO FCTC guidelines regarding restrictions on tobacco POS promotion.

    We examine the effect of food prices on clinical measures of obesity, including body mass index (BMI) and percentage body fat (PBF) measures derived from bioelectrical impedance analysis (BIA) and dual energy X-ray absorptiometry (DXA), among youths ages 12 through 18 in the National Health and Nutrition Examination Survey. This is the first study to consider clinically measured levels of body composition rather than BMI to investigate the effects of food prices on obesity outcomes among youths classified by gender and race/ethnicity. Our findings suggest that increases in the real price per calorie of food for home consumption and the real price of fast-food restaurant food lead to improvements in obesity outcomes among youths. We also find that a rise in the real price of fruits and vegetables leads to increased obesity. Finally, our results indicate that measures of PBF derived from BIA and DXA are no less sensitive and in some cases more sensitive to the prices just mentioned than BMI, and serve an important role in demonstrating that rising food prices (except fruit and vegetable prices) are indeed associated with reductions in obesity rather than with reductions in body size proportions alone.

    Violence, including its occurrence among youth, results in considerable physical, emotional, social, and economic consequences in the U.S. Youth violence prevention work at the Division of Violence Prevention (DVP) at the Centers for Disease Control and Prevention (CDC) emphasizes preventing youth violence-related behaviors, injuries, and deaths by collaborating with academic and community partners and stakeholders. Since 2000, DVP has funded three rounds of CDC's National Centers of Excellence in Youth Violence Prevention (YVPCs) in 5-year cycles, with the goal of supporting university-community partnerships so that the best science can be utilized in order to prevent youth violence. The current YVPCs focus on: (a) partnering with communities to identify community needs; (b) selecting and implementing the best comprehensive evidence-based programs to meet those needs; and (c) rigorously evaluating whether those efforts have a community-level impact on youth violence rates. The introduction to this special issue on the current YVPCs provides a brief historical overview on the YVPC Program; outlines the YVPCs' accomplishments to date; and describes the current YVPCs, their community partners, and their activities. The introduction concludes with an overview of the special issue.

    Background Individuals with Prader–Willi syndrome (PWS) have extremely regulated diets to prevent the development of morbid obesity. Objective This study evaluated potential deficiencies in macro and micronutrients in a cohort of youth with PWS and compared them to a group of children with non-congenital obesity and to US national recommendations. Design Participants were 32 youth with PWS (age=10.8±2.6 years, body fat=46.7±10.1%) and 48 children without PWS but classified as obese (age=9.7±1.2 years, body fat=43.4±5.7%). Participants’ parents completed a training session on food recording before completing a 3-day food record during a typical week including a weekend day and two weekdays, as well as a screening form indicating nutritional supplements use. Results Youth with PWS reported less calories (1,312±75 vs. 1,531±61 kcal, p=0.03), carbohydrate (175±10 vs. 203±8 g), and sugars (67±5 vs. 81±4 g; p=0.04 for both) than obese. Youth with PWS consumed more vegetables (1.1±0.1 vs. 0.6±0.1 cups) and more of them met the daily recommendation (p<0.01 for both). Likewise, youth with PWS consumed more calcium than obese (899±53 vs. 752±43 mg) and more of them met the recommended daily dose (p=0.04 for both). The majority of participants in this study did not meet the vitamin D recommendation. Conclusion Despite consuming less calories, youth with PWS had a similar proportion of macronutrients in their diet as children with obesity. Micronutrient deficiencies in calcium and vitamin D in youth with PWS were noted despite a third of youth with PWS consuming multivitamin supplements. Special attention must be paid to the diets of youth with PWS and with obesity to ensure they are meeting micronutrient needs during this period of growth and development. PMID:26652260

    The scientific interest in high-intensity interval training (HIIT) has greatly increased during recent years. The objective of this meta-analysis was to determine the effectiveness of HIIT interventions on cardio-metabolic risk factors and aerobic capacity in overweight and obese youth, in comparison with other forms of exercise. A computerized search was made using seven databases. The analysis was restricted to studies that examined the effect of HIIT interventions on cardio-metabolic and/or aerobic capacity in pediatric obesity (6-17 years old). Nine studies using HIIT interventions were selected (n = 274). Standarized mean difference (SMD) and 95% confidence intervals were calculated. The DerSimonian-Laird approach was used. HIIT interventions (4-12 week duration) produced larger decreases in systolic blood pressure (SMD = 0.39; -3.63 mmHg) and greater increases in maximum oxygen uptake (SMD = 0.59; 1.92 ml/kg/min) than other forms of exercise. Also, type of comparison exercise group and duration of study were moderators. HIIT could be considered a more effective and time-efficient intervention for improving blood pressure and aerobic capacity levels in obese youth in comparison to other types of exercise. © 2016 World Obesity. © 2016 World Obesity.

    2012-01-01

    Youth onset type 2 diabetes (T2DM) continues to increase worldwide, concomitant with the rising obesity epidemic. There is evidence to suggest that youth with T2DM are affected by the same comorbidities and complications as adults diagnosed with T2DM. This review highlights specifically the kidney disease associated with youth onset T2DM, which is highly prevalent and associated with a high risk of end-stage kidney disease in early adulthood. A general understanding of this complex disease by primary care providers is critical, so that at-risk individuals are identified and managed early in the course of their disease, such that progression can be modified in this high-risk group of children and adolescents. A review of the pediatric literature will include a focus on the epidemiology, risk factors, pathology, screening, and treatment of kidney disease in youth onset T2DM. PMID:22315622

    2018-02-09

    Youth with Serious Emotional Disturbance (SED) have high rates of overweight/obesity. Factors influencing mental health provider intentions to deliver weight-related advice are unclear. This study used qualitative methodology and Theory of Planned Behavior (TPB) constructs to examine these factors. Community mental health providers serving youth with SED were recruited via convenience sampling and an online provider list. Participants completed an open-ended TPB-based questionnaire online. Content analysis identified thematic beliefs. Twenty-one providers completed the questionnaire. Providers identified behavioral beliefs (e.g., client defensiveness), normative beliefs (e.g., medical professionals), and control beliefs (e.g., limited resources) that impact decisions to provide weight-related advice. Knowledge of factors that may influence providers' delivery of weight-related advice may lead to more effective healthy lifestyle programming for youth with SED.

    It is well known that inflammation is associated with diabetes, but it is unclear whether obesity mediates this association in individuals with youth-onset type 2 diabetes mellitus (T2DM-Y). We recruited individuals with T2DM-Y (age at onset <25 years) and age-matched normal glucose tolerance (NGT) subjects. Participants were further classified using Asia-Pacific body mass index cut-points for obesity and categorized as: nonobese NGT (n = 100), Obese NGT (n = 50), nonobese T2DM-Y (n = 50), and obese T2DM-Y (n = 50). We compared adipokines (adiponectin and leptin) and proinflammatory cytokines (tumor necrosis factor alpha [TNF-α] and monocyte chemotactic protein-1 [MCP-1]) across groups. Compared to nonobese NGT, the other 3 groups (obese NGT, nonobese T2DM-Y, and obese T2DM-Y) were found to have lower adiponectin (7.7 vs. 5.7, 4.2, 3.8 μg/mL, P<.01), and higher leptin (3.6 vs. 5.4, 5.7, 7.9 μg/mL, P<.001) and MCP 1 (186 vs. 272, 340, 473 pg/mL, P<.001) respectively. However, TNF-α levels were higher only among nonobese T2DM-Y (112 pg/mL) and obese T2DM-Y (141 pg/mL, P<.01 for each). After adjusting for age, sex, waist, hypertension, homeostatic model assessment of insulin resistance (HOMA-IR), serum cholesterol, triglycerides, and family history of diabetes, adiponectin was associated with 33% and 41% lower odds of being nonobese T2DM and obese T2DM, respectively. However, adjusted for same factors, leptin, TNF-α, and MCP-1 were associated with markedly higher odds (5- to 14-fold) of nonobese and obese T2DM. In young Asian Indians, leptin and proinflammatory cytokines are positively, and adiponectin negatively, associated with both nonobese and obese T2DM-Y compared to nonobese NGT individuals.

    Considering the controversies existent on the subject, the aim of this review is to discuss adherence to diet in obese adolescents. The selection of articles was made in the SCOPUS, COCHRANE, APA Psyc Net, SciELO, LILACS, CAPES Journals, PUBMED/MEDLINE and GOOGLE ACADEMIC databases. Studies published between 2002 and 2012 were selected. There was lack of evidence of conceptual discussion about adherence to diet in obesity in the child-youth context, in addition to scarcity of data on adherence to diet itself in obese adolescents and the methods of evaluating this. Lastly, multiple interdependent factors were found which both facilitated and made the process of adherence to diet difficult for obese youngsters. The majority of these (factors) belong to the socioeconomic and cultural dimension, in addition to pointing out cognitive and psychological factors and those associated with health services and professionals.

    Little is known about longitudinal associations between added sugar consumption (solid and liquid sources) and glucose-insulin homeostasis among youth. Caucasian children (8-10 y) with at least one obese biological parent were recruited in the QUébec Adipose and Lifestyle InvesTigation in Youth (QUALITY) cohort (n = 630) and followed-up 2 y later (n = 564). Added sugars were assessed by 3 24-h dietary recalls at baseline. Two-year changes were examined in multivariate linear regression models, adjusting for baseline level, age, sex, Tanner stage, energy intake, fat mass (dual-energy X-ray absorptiometry), and physical activity (7 d accelerometer). Added sugar intake in either liquid or solid sources was not related to changes in adiposity measures (fat mass, body mass index, or waist circumference). However, a higher consumption (10 g/d) of added sugars from liquid sources was associated with 0.04 mmol/L higher fasting glucose, 2.3 pmol/L higher fasting insulin, 0.1 unit higher homeostasis model assessment of insulin resistance (HOMA-IR), and 0.4 unit lower Matsuda-insulin sensitivity index (Matsuda-ISI) in all participants (P < 0.01). No associations were observed with consumption of added sugars from solid sources. Overweight/obese children at baseline had greater increases in adiposity indicators, fasting insulin, and HOMA-IR and decreases in Matsuda-ISI during those 2 y than normal-weight children. Consumption of added sugars from liquid or solid sources was not associated with changes in adiposity, but liquid added sugars were a risk factor for the development of impaired glucose homeostasis and insulin resistance over 2 y among youth at risk of obesity.

    Overweight and obesity affects 1 in 3 US children and adolescents. Clinical recommendations have largely focused on screening guidelines and counseling strategies. However, the physical examination of the child or adolescent with obesity can provide the clinician with additional information to guide management decisions. This expert-based review focuses on physical examination findings specific to children and adolescents with obesity. For each physical examination element, the authors define the finding and its prevalence among pediatric patients with obesity, discuss the importance and relevance of the finding, describe known techniques to assess severity, and review evidence regarding the need for additional evaluation. The recommendations presented represent a comprehensive review of current evidence as well as expert opinion. The goal of this review is to highlight the importance of conducting a targeted physical examination during pediatric weight management visits.

  2. Modulation of obesity-induced inflammation by dietary fats: mechanisms and clinical evidence

    PubMed Central

    2014-01-01

    Obesity plays a pivotal role in the development of low-grade inflammation. Dietary fatty acids are important modulators of inflammatory responses. Saturated fatty acids (SFA) and n-6 polyunsaturated fatty acids (PUFA) have been reported to exert pro-inflammatory effects. n-3 PUFA in particular, possess anti-inflammatory properties. Numerous clinical studies have been conducted over decades to investigate the impact of dietary fatty acids on inflammatory response in obese individuals, however the findings remained uncertain. High fat meals have been reported to increase pro-inflammatory responses, however there is limited evidence to support the role of individual dietary fatty acids in a postprandial state. Evidence in chronic studies is contradictory, the effects of individual dietary fatty acids deserves further attention. Weight loss rather than n-3 PUFA supplementation may play a more prominent role in alleviating low grade inflammation. In this context, the present review provides an update on the mechanistic insight and the influence of dietary fats on low grade inflammation, based on clinical evidence from acute and chronic clinical studies in obese and overweight individuals.

    The pattern of infant feeding during the first 1000-day period-from conception to the second birthday-has a significant influence on the child's growth trajectory. The relationship between exclusive breastfeeding and lower risk of childhood obesity has elicited much scientific interest, given the fact that this form of malnutrition is becoming a global epidemic. This narrative review aims to examine the evidence in the literature linking exclusive breastfeeding with reduction in obesity in children. Using appropriate search terms, PubMed database was searched for relevant articles that met the review objective. Evidence for the protective effect of exclusive breastfeeding against childhood obesity have been provided by studies which explored 5 physiologic mechanisms and those that established the causality between breastfeeding and lower risk of obesity. The few studies that disputed this relationship highlighted the influence of confounding factors. A new insight on molecular mechanisms, however, points to a direct and indirect effect of human milk oligosaccharides on the prevention of overweight and obesity. The preponderance of current evidence strongly suggests that exclusivity in breastfeeding can prevent the development of obesity in children.

    2017-08-01

    This review provides a rationale for the use of pharmacotherapy in pediatric weight management, summarizes results of some of the key pediatric clinical trials of approved and "off-label" obesity medications, introduces new options in the pediatric pipeline, and offers a glimpse into the future of pediatric obesity medicine. Despite the need for adjunctive treatments to enhance the outcomes of lifestyle modification therapy among youth with obesity, none of the obesity medications evaluated to date have been shown to meaningfully reduce BMI or cardiometabolic risk factors. Promising medications recently approved for the treatment of obesity in adults will soon be tested in pediatric trials, offering hope that new therapeutic options will soon be available. As new medications are approved to treat pediatric obesity, it will be important to evaluate the safety and efficacy of combination pharmacotherapy and investigate predictors of response. Application of precision medicine approaches to the field of pediatric obesity management will improve the long-term outlook for the tens of millions of youth afflicted with this serious and recalcitrant disease.

    Colorado’s adult obesity rate has more than doubled since 1995, prompting its Department of Public Health and Environment to list obesity as its top prevention priority. To initiate comprehensive and effective action, the department used a well-known evidence-based public health framework developed by Brownson and others. This article describes the tools and process developed to conduct 2 of the 7 stages in this framework that challenge public health organizations: reviewing the literature and prioritizing effective strategies from that literature. Forty-five department staff participated in an intensive literature review training to identify physical activity and nutrition strategies that effectively address obesity and worked with external stakeholders to prioritize strategies for the state. Divided into 8 multidisciplinary teams organized by the setting where public health could exert leverage, they scanned the scientific literature to identify potential strategies to implement. These teams were trained to use standardized tools to critique findings, systematically abstract key information, and classify the evidence level for each of 58 identified strategies. Next, departmental subject matter experts and representatives from local public health and nonprofit health agencies selected and applied prioritization criteria to rank the 58 strategies. A team charter, group facilitation tools, and 2 web-based surveys were used in the prioritization stage. This process offered the staff a shared experience to gain hands-on practice completing literature reviews and selecting evidence-based strategies, thereby enhancing Colorado’s obesity prevention efforts and improving public health capacity. Practitioners can use these tools and methodology to replicate this process for other health priorities. PMID:23806801

    Youth-adult partnerships (e.g., youth leading programs, participating as members of advisory boards) are a common and widely recommended practice in youth work and youth-serving program settings. Although researchers have suggested that these opportunities contribute to youth's identity development, empirical evidence is lacking. In the current study, we tested associations between identity style and degree of youth voice, collaborative youth-adult relationships, and youth's program engagement in 194 youth participating in youth-adult partnerships (M age  = 17.6, 62 % female). We found that these characteristics of youth-adult partnerships predicted higher informational identity style, although only program engagement emerged as a unique predictor. Furthermore, exploratory analysis indicated that these associations were moderated by the type of organization. The findings suggest the need for more research on the multiple dimensions of youth-adult partnerships and their association with youth functioning, as well as pointing to the importance of the broader organizational context of youth-adult partnerships.

    B’More Healthy Community for Kids (BHCK) is an ongoing multi-level intervention to prevent childhood obesity in African-American low-income neighborhoods in Baltimore city, MD. Although previous nutrition interventions involving peer mentoring of youth have been successful, there is a lack of studies evaluating the influence of cross-age peers within interventions targeting youth. This article evaluates the implementation of the BHCK intervention in recreation centers, and describes lessons learned. Sixteen youth leaders delivered bi-weekly, interactive sessions to 10- to 14-y olds. Dose, fidelity and reach are assessed, as is qualitative information regarding what worked well during sessions. Dose is operationalized as the number of interactive sessions, and taste tests, giveaways and handouts per session; fidelity as the number of youth leaders participating in the entire intervention and per session and reach as the number of interactions with the target population. Based on a priori set values, number of interactive sessions was high, and number of taste tests, giveaways and handouts was moderate to high (dose). The number of participating youth leaders was also high (fidelity). Of the 14 planned sessions, the intervention was implemented with high/moderate reach. Data suggest that working with cross-age peers is a promising nutritional intervention for recreation centers. PMID:26936480

    Increasing rates of childhood obesity in the USA and other Western countries are a cause for serious public health concern. Neighborhood and community environments are thought to play a contributing role in the development of obesity among youth, but it is not well understood which types of physical environmental characteristics have the most potential to influence obesity outcomes. This paper reports the results of a systematic review of quantitative research examining built and biophysical environmental variables associated with obesity in children and adolescents through physical activity. Literature searches in PubMed, PsychInfo and Geobase were conducted. Fifteen quantitative studies met the inclusion criteria for this systematic review. The majority of studies were cross-sectional and published after 2005. Overall, few consistent findings emerged. For children, associations between physical environmental variables and obesity differed by gender, age, socioeconomic status, population density and whether reports were made by the parent or child. Access to equipment and facilities, neighborhood pattern (e.g. rural, exurban, suburban) and urban sprawl were associated with obesity outcomes in adolescents. For most environmental variables considered, strong empirical evidence is not yet available. Conceptual gaps, methodological limitations and future research directions are discussed.

    In June 2008, the Medical Advisory Secretariat began work on the Diabetes Strategy Evidence Project, an evidence-based review of the literature surrounding strategies for successful management and treatment of diabetes. This project came about when the Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the Ministry's newly released Diabetes Strategy.After an initial review of the strategy and consultation with experts, the secretariat identified five key areas in which evidence was needed. Evidence-based analyses have been prepared for each of these five areas: insulin pumps, behavioural interventions, bariatric surgery, home telemonitoring, and community based care. For each area, an economic analysis was completed where appropriate and is described in a separate report.To review these titles within the Diabetes Strategy Evidence series, please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/masabout.html,DIABETES STRATEGY EVIDENCE PLATFORM: Summary of Evidence-Based AnalysesContinuous Subcutaneous Insulin Infusion Pumps for Type 1 and Type 2 Adult Diabetics: An Evidence-Based AnalysisBehavioural Interventions for Type 2 Diabetes: An Evidence-Based AnalysisBARIATRIC SURGERY FOR PEOPLE WITH DIABETES AND MORBID OBESITY: An Evidence-Based SummaryCommunity-Based Care for the Management of Type 2 Diabetes: An Evidence-Based AnalysisHome Telemonitoring for Type 2 Diabetes: An Evidence-Based AnalysisApplication of the Ontario Diabetes Economic Model (ODEM) to Determine the Cost-effectiveness and Budget Impact of Selected Type 2 Diabetes Interventions in Ontario The purpose of this evidence-based analysis was to examine the effectiveness and cost-effectiveness of bariatric surgery for the management of diabetes in morbidly obese people.

    To review the effects of resistance training programs on pre- and early-pubertal youth in the context of response, potential influence on growth and maturation, and occurrence of injury. Evidence-based review. Twenty-two reports dealing with experimental resistance training protocols, excluding isometric programs, in pre- and early-pubertal youth, were reviewed in the context of subject characteristics, training protocol, responses, and occurrence of injury. Experimental programs most often used isotonic machines and free weights, 2- and 3-day protocols, and 8- and 12-week durations, with significant improvements in muscular strength during childhood and early adolescence. Strength gains were lost during detraining. Experimental resistance training programs did not influence growth in height and weight of pre- and early-adolescent youth, and changes in estimates of body composition were variable and quite small. Only 10 studies systematically monitored injuries, and only three injuries were reported. Estimated injury rates were 0.176, 0.053, and 0.055 per 100 participant-hours in the respective programs. Experimental training protocols with weights and resistance machines and with supervision and low instructor/participant ratios are relatively safe and do not negatively impact growth and maturation of pre- and early-pubertal youth.

    About 3.5% Americans identify themselves as lesbian, gay, or bisexual while 0.3% identify themselves as transgender. The LGBT (lesbian, gay, bisexual, and transgender) community belongs to almost every race, ethnicity, religion, age, and socioeconomic group. The LGBT youth are at a higher risk for substance use, sexually transmitted diseases (STDs), cancers, cardiovascular diseases, obesity, bullying, isolation, rejection, anxiety, depression, and suicide as compared to the general population. LGBT youth receive poor quality of care due to stigma, lack of healthcare providers’ awareness, and insensitivity to the unique needs of this community. The main objective of this literature review is to highlight the challenges faced by the LGBT youth and to enhance the awareness among physicians about the existing disparities in order to provide a more comprehensive, evidence-based, and humane medical care to this community.

    Potential obesity-related policy approaches have recently been receiving more attention. While some have been implemented and others only proposed, few have been formally evaluated. We discuss the relevance, and in some cases irrelevance, of some of the types of evidence that are often brought to bear in considering obesity-related policy decisions. We discuss major methods used to generate such evidence, emphasizing study design and the varying quality of the evidence obtained. Third, we consider what the standards of evidence should be in various contexts, who ought to set those standards, as well as the inherent subjectivity involved in making policy decisions. Finally, we suggest greater transparency from both academics and policymakers in the acknowledgment of subjectivities so they can distinguish and communicate the roles played by empirical evidence and subjective values in the formulation of policy.

    Background: The pattern of infant feeding during the first 1000-day period—from conception to the second birthday—has a significant influence on the child’s growth trajectory. The relationship between exclusive breastfeeding and lower risk of childhood obesity has elicited much scientific interest, given the fact that this form of malnutrition is becoming a global epidemic. Aim: This narrative review aims to examine the evidence in the literature linking exclusive breastfeeding with reduction in obesity in children. Literature search: Using appropriate search terms, PubMed database was searched for relevant articles that met the review objective. Results: Evidence for the protective effect of exclusive breastfeeding against childhood obesity have been provided by studies which explored 5 physiologic mechanisms and those that established the causality between breastfeeding and lower risk of obesity. The few studies that disputed this relationship highlighted the influence of confounding factors. A new insight on molecular mechanisms, however, points to a direct and indirect effect of human milk oligosaccharides on the prevention of overweight and obesity. Conclusions: The preponderance of current evidence strongly suggests that exclusivity in breastfeeding can prevent the development of obesity in children. PMID:28469518

    OBJECTIVE. This study examined the relationship between childhood obesity and overweight and functional activity and its enjoyment. METHOD. A cross-sectional design was used to analyze data from the 2012 National Health and Nutrition Examination Survey National Youth Fitness Survey. Multivariate logistic regression models were used. RESULTS. Data for 1,640 children ages 3–15 yr were retrieved. Physical activity was negatively associated with risk of obesity (odds ratio [OR] = 0.93; 95% confidence interval [CI] [0.87, 0.98]). Although children who were obese and overweight were more likely to have functional limitations (ORs = 1.58–1.61), their enjoyment of physical activity participation was not significantly different from that of the healthy-weight group. CONCLUSION. Physical activity lowered the risk of obesity. Children who were obese had functional limitations compared with healthy-weight children, but both groups enjoyed physical activity equally. Future studies are needed to determine barriers to participation among these children in recreation and sporting activities. PMID:27548862

    As evidence grows about the benefits of policy and environmental changes to support active living and healthy eating, effective tools for implementing change must be developed. Youth advocacy, a successful strategy in the field of tobacco control, should be evaluated for its potential in the field of obesity prevention. San Diego State University collaborated with the San Diego County Childhood Obesity Initiative to evaluate Youth Engagement and Action for Health! (YEAH!), a youth advocacy project to engage youth and adult mentors in advocating for neighborhood improvements in physical activity and healthy eating opportunities. Study objectives included documenting group process and success of groups in engaging in community advocacy with decision makers. In 2011 and 2012, YEAH! group leaders were recruited from the San Diego County Childhood Obesity Initiative's half-day train-the-trainer seminars for adult leaders. Evaluators collected baseline and postproject survey data from youth participants and adult group leaders and interviewed decision makers. Of the 21 groups formed, 20 completed the evaluation, conducted community assessments, and advocated with decision makers. Various types of decision makers were engaged, including school principals, food service personnel, city council members, and parks and recreation officials. Eleven groups reported change(s) implemented as a result of their advocacy, 4 groups reported changes pending, and 5 groups reported no change as a result of their efforts. Even a brief training session, paired with a practical manual, technical assistance, and commitment of adult leaders and youth may successfully engage decision makers and, ultimately, bring about change.

    The Canadian Society for Exercise Physiology (CSEP), in partnership with the Healthy Active Living and Obesity Research Group (HALO) at the Children's Hospital of Eastern Ontario Research Institute, and in collaboration with ParticipACTION, and others, has developed the Canadian Sedentary Behaviour Guidelines for Children (aged 5-11 years) and Youth (aged 12-17 years). The guidelines include a preamble to provide context, followed by the specific recommendations for sedentary behaviour. The entire development process was guided by the Appraisal of Guidelines for Research Evaluation (AGREE) II instrument, which is the international standard for clinical practice guideline development. Thus, the guidelines have gone through a rigorous and transparent developmental process and the recommendations are based on evidence from a systematic review and interpretation of the research evidence. The final guidelines benefitted from an extensive online consultation process with 230 domestic and international stakeholders and key informants. The final guideline recommendations state that for health benefits, children (aged 5-11 years) and youth (aged 12-17 years) should minimize the time that they spend being sedentary each day. This may be achieved by (i) limiting recreational screen time to no more than 2 h per day - lower levels are associated with additional health benefits; and (ii) limiting sedentary (motorized) transport, extended sitting time, and time spent indoors throughout the day. These are the first evidence-based Canadian Sedentary Behaviour Guidelines for Children and Youth and provide important and timely recommendations for the advancement of public health based on a systematic synthesis, interpretation, and application of the current scientific evidence.

    Family relationships have been linked to obesity and related disorders in youth, but few studies have provided causal evidence of this association. This study tested the impact of a family psychosocial intervention on components of metabolic syndrome-a condition driven largely by abdominal obesity-in African American youth. In particular, the study tested whether effects were strongest among those who started at highest risk, that is, with high levels of unsupportive parenting at baseline. Randomized clinical trial of a community sample of 391 African American youth (mean age=11.2 years) conducted in 2001-2002, with follow-up metabolic syndrome assessment in 2014-2015. Participants were assigned either to receive a weekly family intervention or to a control group. The primary study outcome was the number of components of metabolic syndrome that were clinically elevated at age 25, including central adiposity, blood pressure, triglycerides, glucose and low high-density lipoproteins. Unsupportive parenting was measured by questionnaires at baseline. Significant interaction effects were found between group assignment and baseline unsupportive parenting on counts of metabolic syndrome components in youth (beta=-0.17, P=0.03). Among those who started with higher levels of unsupportive parenting at age 11, participation in the family intervention reduced the number of clinically elevated components of the metabolic syndrome at age 25 relative to the control group. No such effect was seen among those who started with good parenting. Mediation analyses suggested that changes in the psychosocial targets of the parenting intervention partially accounted for the effects amongst those high in unsupportive parenting at baseline (effect size=-0.350, s.e.=0.178). These findings suggest that efforts to improve family relationships may be able to ameliorate the detrimental effects that harsh and unsupportive parenting have on obesity-related outcomes such as metabolic syndrome in

    The efficiency of traditional anthropometric measurements such as body mass index (BMI) or waist circumference (Waist C) used to replace biomedical imaging for assessing visceral adipose tissue (VAT) is still highly controversial in youth. We evaluated the most accurate model predicting VAT in overweight/obese youth, using various anthropometric measurements and their correlation with different body fat compartments, especially by testing, for the first time in youth, the hypothesis that subtracting the anthropometric measurement the most highly correlated with subcutaneous abdominal adipose tissue (SAAT) and less correlated possible with VAT from an anthropometric abdominal measurement highly correlated with visceral and total abdominal adipose tissue (TAAT), predicts VAT with higher accuracy. VAT and SAAT data resulted from magnetic resonance imaging (MRI) analysis performed on 181 boys and girls (7-17 y) from Diabetes & Endocrinology Care Paediatrics Clinic in Luxembourg. Height, weight, abdominal diameters, waist, hip, and thigh circumferences were measured with a view to developing the anthropometric VAT predictive algorithms. In girls, subtracting proximal thigh circumference (Proximal Thigh C), the most closely correlated anthropometric measurement with SAAT, from Waist C, the most closely correlated anthropometric measurement with VAT was instrumental in improving VAT prediction, in comparison with the most accurate single VAT anthropometric surrogate. [Formula: see text] Residual analysis showed a negligible estimation error (5 cm 2 ). In boys, Waist C was the best VAT predictor. Subtraction of abdominal subcutaneous fat is important to predict VAT in overweight/obese girls. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Purpose To examine differences in self-reported perceived mental and physical health status (PHS), as well as known cardiometabolic risk factors in a sample of normal weight, overweight, and obese Mexican youths. Methods Cross-sectional analysis of 164 youths aged 11-18 years recruited in Cuernavaca, Mexico. Participants completed a self-administered questionnaire that included measures of generic and weight-specific quality of life (QoL), perceived health, physical function, depressive symptoms, and body shape satisfaction. Height, weight and waist circumference were measured and body mass index (BMI) was determined. Fasting blood samples from participants yielded levels of glucose, triglycerides, and cholesterol (total, HDL and LDL). Results Nearly 50% of participants were female, 21% had a normal BMI, 39% were overweight, and 40% were obese. Obese youths reported significantly lower measures of PHS and showed an increase in cardiometabolic risk, compared to normal weight youths. Physical functioning, generic and weight-specific QoL were inversely associated with BMI, waist circumference and glucose. Depressive symptoms were positively correlated with BMI, waist circumference, glucose levels and HDL cholesterol. No correlation was found between PHS and cardiometabolic risk measures after controlling for BMI. Conclusions In this sample of Mexican youths, obesity was associated with a significantly lower PHS and increased cardiometabolic risk. PMID:25648756

    2017-06-01

    Despite accumulating evidence linking screen-based sedentary behaviours (i.e. screen time) with poorer health outcomes among children and youth <18 years of age, the prevalence of these behaviours continues to increase, with roughly half of children and youth exceeding the public health screen time recommendation of 2 h per day or less. The purpose of this article is to provide an overview of key research initiatives aimed at understanding the associations between screen time and health indicators including physical health, quality of life and psychosocial health. Available evidence suggests that screen time is deleteriously associated with numerous health indicators in child and youth populations, including adiposity, aerobic fitness, quality of life, self-esteem, pro-social behaviour, academic achievement, depression and anxiety. However, few longitudinal or intervention studies have been conducted, with most of these studies focusing on physical health indicators. While most studies have used self-reported assessments of screen time, the availability of more objective assessment methods presents important opportunities (e.g. more accurate and precise assessment of sedentary time and screen time) and challenges (e.g. privacy and participant burden). Novel statistical approaches such as isotemporal substitution modelling and compositional analysis, as well as studies using longitudinal and experimental methodologies, are needed to better understand the health impact of excessive screen time, and to develop strategies to minimise or reverse the negative impacts of these behaviours. The evidence to date suggests a clear need for policy aimed at minimising the hazardous health consequences associated with screen time among children and youth.

    Antipsychotic-treated youth have increased risk for the development of obesity and type 2 diabetes. Behavioral weight loss treatments show promise in reducing obesity and diabetes risk in antipsychotic treated adults, but have received no study in antipsychotic treated youth. We describe a rationale for behavioral weight loss interventions in high-weight antipsychotic treated youth, and report behavioral, anthropomorphic, and metabolic findings from a case series of obese antipsychotic-treated adolescents participating in a short-term, family-based behavioral weight loss intervention. We adapted the Traffic Light Plan, a 16-week family-based weight loss intervention that promotes healthy energy balance using the colors of the traffic light to categorize the nutritional value of foods and intensity of physical activity, adapting a social ecological framework to address health behavior change in multiple social contexts. The intervention was administered to three obese adolescents with long-term antipsychotic medication exposure. Efficacy of the intervention was evaluated with a battery of anthropomorphic and metabolic assessments including weight, body mass index percentile, whole body adiposity, liver fat content, and fasting plasma glucose and lipids. Participants and their parents also filled out a treatment satisfaction questionnaire upon study completion. Two males and 1 female (all aged 14 years) participated. All 3 participants attended all 16 sessions, and experienced beneficial changes in adiposity, fasting lipids and liver fat content associated with weight stabilization or weight loss. Adolescents and their parents all reported a high level of satisfaction with the treatment. Family-based behavioral weight loss treatment can be feasibly delivered and is acceptable to antipsychotic-treated youth and their families. Randomized controlled trials are needed to fully evaluate the effectiveness and acceptability of behavioral weight loss interventions in

    Assessing energy requirements is a fundamental activity in clinical dietetics practice. A study was designed to determine whether published linear regression equations were accurate for predicting resting energy expenditure (REE) in fasted Hispanic children with obesity (aged 7 to 15 years). REE was measured using indirect calorimetry; body composition was estimated with whole-body air displacement plethysmography. REE was predicted using four equations: Institute of Medicine for healthy-weight children (IOM-HW), IOM for overweight and obese children (IOM-OS), Harris-Benedict, and Schofield. Accuracy of the prediction was calculated as the absolute value of the difference between the measured and predicted REE divided by the measured REE, expressed as a percentage. Predicted values within 85% to 115% of measured were defined as accurate. Participants (n=58; 53% boys) were mean age 11.8±2.1 years, had 43.5%±5.1% body fat, and had a body mass index of 31.5±5.8 (98.6±1.1 body mass index percentile). Measured REE was 2,339±680 kcal/day; predicted REE was 1,815±401 kcal/day (IOM-HW), 1,794±311 kcal/day (IOM-OS), 1,151±300 kcal/day (Harris-Benedict), and, 1,771±316 kcal/day (Schofield). Measured REE adjusted for body weight averaged 32.0±8.4 kcal/kg/day (95% confidence interval 29.8 to 34.2). Published equations predicted REE within 15% accuracy for only 36% to 40% of 58 participants, except for Harris-Benedict, which did not achieve accuracy for any participant. The most frequently accurate values were obtained using IOM-HW, which predicted REE within 15% accuracy for 55% (17/31) of boys. Published equations did not accurately predict REE for youth in the study sample. Further studies are warranted to formulate accurate energy prediction equations for this population.

    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.

    Experts recommend that clinicians assess motivational factors before initiating care for pediatric obesity. Currently, there are no well-established clinical tools available for assessing motivation in youth with obesity or their families. This represents an important gap in knowledge since motivation-related information may shed light on which patients might fail to complete treatment programs. Our study was designed to evaluate the measurement properties and utility of the Readiness and Motivational Interview for Families (RMI-Family), a structured interview that utilizes a motivational interviewing approach to (i) assess motivational factors in youth and their parents, and (ii) examine the degree to which motivation and motivation-related concordance between youth and parents are related to making changes to lifestyle habits for managing obesity in youth. From 2016 to 2020, this prospective study will include youth with obesity (body mass index [BMI] ≥97th percentile; 13-17 years old; n = 250) and their parents (n = 250). The study will be conducted at two primary-level, multidisciplinary obesity management clinics based at children's hospitals in Alberta, Canada. Participants will be recruited and enrolled after referral to these clinics, but prior to initiating clinical care. Each youth and their parent will complete the RMI-Family (~1.5 h) at baseline, and 6- and 12-months post-baseline. Individual (i.e., youth or parent) and family-level (i.e., across youth and parent) responses to interview questions will be scored, as will aspects of interview administration (e.g., fidelity to motivational interviewing tenets). The RMI-Family will also be examined for test-retest reliability. Youth data collected at each time point will include demography, anthropometry, lifestyle habits, psychosocial functioning, and health services utilization.

    There is evidence to suggest that excessive television viewing is an independent determinant of obesity in young people. However, the pathways between television viewing and obesity are not fully understood. Therefore, the purpose of this study was to examine whether the relationship between television and body mass index (BMI) is mediated by television snacking and junk food consumption. Results are based on 15,973 youth in grades 6-10 who participated in the Canadian 2009/2010 health behaviour in school-aged children survey (HBSC). Participants self-reported their weight and height and BMI z-scores were calculated based on World Health Organization growth standards. Participants reported the frequency of snacking while watching television and the frequency of eating junk food (sweets, soft drinks, baked goods, French fries, potato chips). Total hours per week of television were calculated. A contemporary multiple mediation analysis was used to examine associations. A modest positive relationship was observed between television viewing and BMI. The mean BMI z-score was 0.15 units higher in youth in the highest television viewing quartile by comparison with the youth in the lowest quartile. However, contrary to our hypothesis, television snacking and junk food consumption were not significant positive mediators of the television and BMI relationship. The pathways between television viewing and obesity are complicated and remain poorly understood. Future research using longitudinal or experimental designs, more precise measurement tools and formal mediation analyses is needed. This research should consider mediators related to both energy intake and expenditure. © 2012 The Authors. Pediatric Obesity © 2012 International Association for the Study of Obesity.

    We examined the associations among daily cortisol, physical activity (MVPA) and continuous metabolic syndrome score (cMetS) in obese youth. Fifty adolescents (mean age 14.8 ± 1.9 years) were recruited from medical clinics. Daily MVPA (min/day) was assessed by accelerometry. Saliva was sampled at prescribed times: immediately upon waking; 30 min after waking; and 3, 6 and 9 h after waking. Fasting lipids, glucose, waist circumference and blood pressure were used to calculate a continuous metabolic syndrome score (cMetS). Multiple linear regression analysis was used to examine associations among variables. The mean cMetS score was 4.16 ± 4.30 and did not differ by clinic or sex. No significant relationship was found between cortisol area under the curve (cAUC) and cMetS, nor did the interaction of MVPA with cAUC significantly predict cMetS. Physical activity, cortisol, and metabolic risk were not associated in this sample of obese adolescents. Future research should examine the role of insulin sensitivity in these relationships.

    To identify factors which limit the ability of local governments to make appropriate investments in the built environment to promote youth health and reduce obesity outcomes in Atlantic Canada. Policy-makers and professionals participated in focus groups to discuss the receptiveness of local governments to introducing health considerations into decision-making. Seven facilitated focus groups involved 44 participants from Atlantic Canada. Thematic discourse analysis of the meeting transcripts identified systemic barriers to creating a built environment that fosters health for youth aged 12-15 years. Participants consistently identified four categories of barriers. Financial barriers limit the capacities of local government to build, maintain and operate appropriate facilities. Legacy issues mean that communities inherit a built environment designed to facilitate car use, with inadequate zoning authority to control fast food outlets, and without the means to determine where schools are built or how they are used. Governance barriers derive from government departments with distinct and competing mandates, with a professional structure that privileges engineering, and with funding programs that encourage competition between municipalities. Cultural factors and values affect outcomes: people have adapted to car-oriented living; poverty reduces options for many families; parental fears limit children's mobility; youth receive limited priority in built environment investments. Participants indicated that health issues have increasing profile within local government, making this an opportune time to discuss strategies for optimizing investments in the built environment. The focus group method can foster mutual learning among professionals within government in ways that could advance health promotion.

    Group sports interventions have been developed to improve health-related physical fitness of overweight/obese youth. However, its benefits are not systematically documented. This study synthesizes the evidence about the effects of group sports on health-related physical fitness of overweight/obese youth. Pubmed, Web of Knowledge, Scopus, Medline, CINAHL, SportDiscus, and Academic Search Complete were searched in February 2016. Studies assessing the effects of group sports on body composition, cardiorespiratory endurance, muscle strength, flexibility, and neuromotor fitness of overweight/obese youth (aged <18 years) were included. Effect sizes (ES) were calculated with Cohen's d and its 95% confidence intervals (CI). Improvements were found in (i) body composition - percentage of fat body mass (pooled ES = 0.67; 95% CI = 0.24-1.10) and waist circumference (ES = 0.69; P = 0.004); (ii) cardiorespiratory endurance - peak oxygen consumption (pooled ES = 0.53; 95% CI = 0.13-0.92) and (iii) muscle strength - hand grip strength (ES = 0.72; P = 0.003). No significant effects were found for body mass index (pooled ES = 0.27; 95% CI = -0.14 to 0.69), percentage of lean body mass (ES = 0.01; P > 0.05), maximal power output (ES from 0 to 0.06; P > 0.05), sit-and-reach test (pooled ES = 0.26; 95% CI = -0.16 to 0.68) and agility test (ES = 0; P = 0.48). Group sports improve body composition, cardiorespiratory endurance, and hand grip strength of overweight/obese youth.

    Nearly 40% of US women of childbearing age are obese. Obesity during pregnancy is associated with multiple risks for both the woman and fetus, yet clinicians often feel unprepared to provide optimal antepartum care for this group of women. We collected and reviewed current evidence concerning antepartum care of women who are obese during pregnancy. We conducted a systematic review using PRISMA guidelines. Current evidence relating to the pregnancy care of women with a prepregnancy body mass index of 30kg/m 2 or higher was identified using MEDLINE databases via PubMed, Embase, and Web of Science Core Collection between January 2012 and February 2018. A total of 354 records were located after database searches, of which 63 met inclusion criteria. Topic areas for of included studies were: pregnancy risk and outcomes related to obesity, communication between women and health care providers, gestational weight gain and activity/diet, diabetic disorders, hypertensive disorders, obstructive sleep apnea, mental health, pregnancy imaging and measurement, late antepartum care, and preparation for labor and birth. Midwives and other health care providers can provide better antepartum care to women who are obese during pregnancy by incorporating evidence from the most current clinical investigations. © 2018 by the American College of Nurse-Midwives.

    The specific eating pattern of Binge Eating Disorder (BED) patients has provoked the assumption that BED might represent a phenotype within the obesity spectrum that is characterized by increased impulsivity. Following the guidelines of the PRISMA statement (preferred reporting items for systematic reviews and meta-analyses), we here provide a systematic update on the evidence on food-related impulsivity in obese individuals, with and without BED, as well as normal-weight individuals. We separately analyzed potential group differences in the impulsivity components of reward sensitivity and rash-spontaneous behavior. Our search resulted in twenty experimental studies with high methodological quality. The synthesis of the latest evidence consolidates conclusions drawn in our initial systematic review that BED represents a distinct phenotype within the obesity spectrum that is characterized by increased impulsivity. Rash-spontaneous behavior in general, and specifically towards food, is increased in BED, while food-specific reward sensitivity is also increased in obese individuals without BED, but potentially to a lesser degree. A major next step for research entails the investigation of sub-domains and temporal components of inhibitory control in BED and obesity. Based on the evidence of impaired inhibitory control in BED, affected patients might profit from interventions that address impulsive behavior.

    American Indian and Alaska Native (AI/AN) youth face multiple health challenges compared to other racial/ethnic groups, which could potentially be ameliorated by the dissemination of evidence-based adolescent health promotion programs. Previous studies have indicated that limited trained personnel, cultural barriers, and geographic isolation may hinder the reach and implementation of evidence-based health promotion programs among AI/AN youth. Although Internet access is variable in AI/AN communities across the United States, it is swiftly and steadily improving, and it may provide a viable strategy to disseminate evidence-based health promotion programs to this underserved population. We explored the potential of using the Internet to disseminate evidence-based health promotion programs on multiple health topics to AI/AN youth living in diverse communities across 3 geographically dispersed regions of the United States. Specifically, we assessed the Internet's potential to increase the reach and implementation of evidence-based health promotion programs for AI/AN youth, and to engage AI/AN youth. This randomized controlled trial was conducted in 25 participating sites in Alaska, Arizona, and the Pacific Northwest. Predominantly AI/AN youth, aged 12-14 years, accessed 6 evidence-based health promotion programs delivered via the Internet, which focused on sexual health, hearing loss, alcohol use, tobacco use, drug use, and nutrition and physical activity. Adult site coordinators completed computer-based education inventory surveys, connectivity and bandwidth testing to assess parameters related to program reach (computer access, connectivity, and bandwidth), and implementation logs to assess barriers to implementation (program errors and delivery issues). We assessed youths' perceptions of program engagement via ratings on ease of use, understandability, credibility, likeability, perceived impact, and motivational appeal, using previously established measures.

    From 1999-2014, obesity prevalence increased among adults and youth. Obese individuals may be uniquely susceptible to the proinflammatory effects of ozone because obese humans and animals have been shown to experience a greater decline in lung function than normal-weight subjects. Obesity is independently associated with limitations in lung mechanics with increased ozone dose. However, few epidemiologic studies have examined the interaction between excess weight and ozone exposure among adults. Using PubMed keyword searches and reference lists, we reviewed epidemiologic evidence to identify potential response-modifying factors and determine if obese or overweight adults are at increased risk of ozone-related health effects. We initially identified 170 studies, of which seven studies met the criteria of examining the interaction of excess weight and ozone exposure on cardiopulmonary outcomes in adults, including four short-term ozone exposure studies in controlled laboratory settings and three community epidemiologic studies. In the studies identified, obesity was associated with decreased lung function and increased inflammatory mediators. Results were inconclusive about the effect modification when data were stratified by sex. Obese and overweight populations should be considered as candidate at-risk groups for epidemiologic studies of cardiopulmonary health related to air pollution exposures. Air pollution is a modifiable risk factor that may decrease lung function among obese individuals with implications for environmental and occupational health policy.

  1. Autonomic Dysfunction: A Possible Pathophysiological Pathway Underlying the Association Between Sleep and Obesity in Children At-Risk for Obesity

    While mounting evidence suggests that sleep plays an important role in the etiology of obesity, the underlying pathogenic pathways are complex and unresolved. Experimental sleep deprivation studies demonstrate sympathovagal imbalance, indicative of diminished parasympathetic activity and/or heightened sympathetic activity, is consequent to poor sleep. Further, obese children exhibit sympathovagal imbalance, particularly during the night, compared to non-obese children. The question remains whether sympathovagal imbalance is one potential pathophysiological pathway underlying the association between sleep and obesity. The aim of the present study was to examine whether sympathovagal imbalance contributed to the association between sleep and obesity in children. Participants included 564 children aged 10 to 12 years (M = 11.67, SD = 0.95; 43.5 % girls) from the QUALITY Cohort, a longitudinal study of children at-risk for the development of obesity. While children were at-risk due to confirmed parental obesity status, 57.7 % of children were of normal body mass index (5–85th percentile). Sleep duration, sleep timing, and sleep disturbances were based on child- and parent-report. Anthropometrics were measured for central adiposity (waist circumference) and body composition (body mass index, fat mass index). Sympathovagal imbalance was derived from heart rate variability spectral analyses. Estimated path coefficients revealed that sympathovagal imbalance partially contributed to the association between poor sleep (later bedtimes, sleep-disordered breathing) and obesity. These findings highlight the importance of better understanding sympathovagal imbalance and its role in the etiology and maintenance of obesity. Future research should consider investigating nocturnal sympathovagal balance in youth. PMID:25480401

    Long-term solutions to the childhood obesity epidemic will require concerted interdisciplinary efforts that are sensitive to both individual and social determinants of health. The Junior Doctors of Health© (JDOH) program involves interprofessional education (IPE) with university students from health science fields (e.g., medicine, pharmacy, social work, public health) who deliver an interactive program in teams to at-risk school-aged youth. The purpose of this study was to assess the impact of participation in the JDOH IPE program on university students' beliefs about childhood obesity. Fifty-three of the 71 health sciences students enrolled in the JDOH IPE program between 2011 and 2013 participated in this study. Pre- and post-surveys assessed students' beliefs about the importance, causes of, and responsibility for reducing childhood obesity with both closed- and open-ended questions. In 2013, quantitative data were analyzed using Wilcoxon matched-pairs signed-rank tests and qualitative data were analyzed through open coding to identify emergent themes. Results indicate that after participation in the JDOH IPE program, students' identification of social and environmental causes of childhood obesity increased significantly. Further, students' ranking of the importance of obesity was initially higher than those of different issues typically portrayed as social or environmental (e.g., youth violence) but it was similarly ranked after participation in JDOH. This suggests a greater sensitivity to social and environmental challenges faced by youth. Findings suggest that IPE experiences that bring clinical and community-oriented health professions together to engage with disadvantaged youth foster sensitivity to the complexities of childhood obesity in low-income settings.

    Context Peripubertal obesity is associated with abnormal sex steroid concentrations, but the timing of onset and degree of these abnormalities remain unclear. Objective To assess the degree of hyperandrogenemia across puberty in obese girls, and to assess overnight sex steroid changes in Tanner 1–3 girls. Design Cross-sectional analysis. Setting General Clinical Research Centers. Subjects Thirty normal weight (BMI-for-age < 85%) and 74 obese (BMI-for-age ≥ 95%) peripubertal girls. Intervention Blood samples (circa 0500–0700 h) while fasting. Samples from the preceding evening (circa 2300 h) were obtained in 23 Tanner 1–3 girls. Main outcome measures Hormone concentrations stratified by Tanner stage. Results Compared to normal weight girls, mean free testosterone (T) was elevated 2- to 9-fold across puberty in obese girls, while fasting insulin was 3-fold elevated in obese Tanner 1–3 girls (P < 0.05). Mean LH was lower in obese Tanner 1 and 2 girls (P < 0.05), but not in more mature girls. In a subgroup of normal weight Tanner 1–3 girls (n = 17), mean progesterone (P) and T increased overnight 2.3- and 2.4-fold, respectively (P ≤ 0.001). In obese Tanner 1–3 girls (n = 6), evening P and T were elevated, and both tended to increase overnight (mean 1.4- and 1.6-fold, respectively [P = 0.06]). Conclusions Peripubertal obesity is associated with hyperandrogenemia and hyperinsulinemia throughout puberty, being especially marked shortly before and during early puberty. Progesterone and testosterone concentrations in normal weight Tanner 1–3 girls increase overnight, with similar but less evident changes in obese girls. PMID:17118995

    Homeless youth are a growing, vulnerable population with specific primary health care (PHC) requirements. There are no systematic reviews of evidence to guide the delivery of PHC interventions to best address the needs of homeless youth in Australia. We present a narrative synthesis of peer reviewed research designed to determine: (1) the PHC services homeless youth access; (2) experiences of services, reported outcomes and barriers to use; and, (3) the PHC service needs of homeless youth. Findings show that homeless youth access a variety of services and delivery approaches. Increased PHC use is associated with youth who recognise they need help. Street-based clinic linked services and therapy and case management alongside improved housing can positively impact upon mental health and substance use outcomes. Barriers to service use include knowledge; provider attitudes, financial constraints and inappropriate environments. Findings support targetted, co-ordinated networks of PHC and housing services with nurses working alongside community workers.

    Reducing childhood obesity remains a public health priority given its high prevalence and its association with increased risk of adult obesity and chronic diseases. The objective of this study was to examine the joint influence of multiple risk factors on adolescent overweight status. We conducted a random-digit-dialed telephone survey of adolescents aged 12 to 19 years in fall 2008 in a Midwestern city in Nebraska. On the basis of survey data for 791 youths aged 12 to 18 years, we conducted latent class analysis to group youths by the joint occurrence of dietary behavior, physical activity, parenting practices, and physician advice. We then examined the association between the groups and overweight status by using logistic regression, controlling for age, sex, race/ethnicity, and parent and family information. Youths were clustered into 3 groups. Group I (52%) were youths with healthy dietary behavior and physical activity, less permissive parenting practices, and physician advice; Group II (30%) were youths with moderately healthy dietary behavior and physical activity, less permissive parenting practices, and no physician advice; and Group III (18%) were youths with unhealthy dietary behavior and physical activity, permissive parenting practices, and physician advice. Youths in Groups I and II were less likely to be overweight than youths in Group III. Youths with healthier behavior and less permissive parenting practices were less likely to be overweight. Study findings highlight the need to address obesity risk factors among youths with unhealthy dietary behavior, inadequate exercise, permissive parenting practices, and some physician advice. Tailored interventions should be used to target youths with different obesity risk factors.

    Children with Down syndrome (DS) are more likely to be overweight or obese than the general population of youth without DS. To review the prevalence of overweight and obesity and their determinants in youth with DS. The health consequences and the effectiveness of interventions were also examined. A search using MEDLINE, Embase, Web of Science, Scopus, CINAHL, PsycINFO, SPORTDiscus, LILACS, and COCHRANE was conducted. From a total of 4280 studies, we included 45 original research articles published between 1988 and 2015. The combined prevalence of overweight and obesity varied between studies from 23% to 70%. Youth with DS had higher rates of overweight and obesity than youths without DS. Likely determinants of obesity included increased leptin, decreased resting energy expenditure, comorbidities, unfavorable diet, and low physical activity levels. Obesity was positively associated with obstructive sleep apnea, dyslipidemia, hyperinsulinemia, and gait disorder. Interventions for obesity prevention and control were primarily based on exercise-based programs, and were insufficient to achieve weight or fat loss. Population-based research is needed to identify risk factors and support multi-factorial strategies for reducing overweight and obesity in children and adolescents with DS.

    In New Zealand, the burden of obesity is greatest among Pacific people, especially in children and adolescents. We investigated the factors of the obesogenic environment that were indigenous to Pasifika youths' social-cultural context, their food purchasing behaviours, and associated anthropometric measures. An exploratory study of 30 Pasifika youth aged 16-24 years in Wellington and Auckland, New Zealand. A large proportion of the participants were obese (mean body mass index: 31.0kg/m2; waistto-hip ratio: 0.84; waist-to-height ratio: 0.6), suggesting that the future health and wellbeing trajectory of the studied Pasifika youth is poor. Purchasing behaviours of food and snacks over a 7-day period provided meaningful insights that could be a useful future research tool to examine the role of their physical environment on food access and availability. From this exploratory study, we highlight the following: (i) the future health trajectory of Pasifika youth is poor. Developing the youths' healthy lifestyle knowledge may lend itself to developing culturally relevant intervention programmes; (ii) identifying the enablers and barriers within the Pasifika ontext of an obesogenic environment can provide very useful information; (iii) use of spatial analysis using purchased food receipts adds to the current knowledge base of obesity-related research, although this was an exploratory investigation. We need to address these highlights if we are to reverse the trend of obesity for this population.

  8. Food Prices and Obesity: Evidence and Policy Implications for Taxes and Subsidies

    Context: Pricing policies have been posited as potential policy instruments to address the increasing prevalence of obesity. This article examines whether altering the cost of unhealthy, energy-dense foods, compared with healthy, less-dense foods through the use of fiscal pricing (tax or subsidy) policy instruments would, in fact, change food consumption patterns and overall diet enough to significantly reduce individuals' weight outcomes. Methods: This article examined empirical evidence regarding the food and restaurant price sensitivity of weight outcomes based on a literature search to identify peer-reviewed English-language articles published between 1990 and 2008. Studies were identified from the Medline, PubMed, Econlit, and PAIS databases. The fifteen search combinations used the terms obesity, body mass index, and BMI each in combination with the terms price, prices, tax, taxation, and subsidy. Findings: The studies reviewed showed that when statistically significant associations were found between food and restaurant prices (taxes) and weight outcomes, the effects were generally small in magnitude, although in some cases they were larger for low–socioeconomic status (SES) populations and for those at risk for overweight or obesity. Conclusions: The limited existing evidence suggests that small taxes or subsidies are not likely to produce significant changes in BMI or obesity prevalence but that nontrivial pricing interventions may have some measurable effects on Americans' weight outcomes, particularly for children and adolescents, low-SES populations, and those most at risk for overweight. Additional research is needed to be able to draw strong policy conclusions regarding the effectiveness of fiscal-pricing interventions aimed at reducing obesity. PMID:19298422

This article examined empirical evidence regarding the food and restaurant price sensitivity of weight outcomes based on a literature search to identify peer-reviewed English-language articles published between 1990 and 2008. Studies were identified from the Medline, PubMed, Econlit, and PAIS databases. The fifteen search combinations used the terms obesity, body mass index, and BMI each in combination with the terms price, prices, tax, taxation, and subsidy. The studies reviewed showed that when statistically significant associations were found between food and restaurant prices (taxes) and weight outcomes, the effects were generally small in magnitude, although in some cases they were larger for low-socioeconomic status (SES) populations and for those at risk for overweight or obesity. The limited existing evidence suggests that small taxes or subsidies are not likely to produce significant changes in BMI or obesity prevalence but that nontrivial pricing interventions may have some measurable effects on Americans' weight outcomes, particularly for children and adolescents, low-SES populations, and those most at risk for overweight. Additional research is needed to be able to draw strong policy conclusions regarding the effectiveness of fiscal-pricing interventions aimed at reducing obesity.

    Children with overweight/obesity and congenital heart disease (CHD) are at increased cardiovascular risk. A lifestyle intervention may help reduce these risks. We sought to determine the feasibility of a smartphone-based lifestyle intervention to improve cardiovascular health outcomes in children with overweight/obesity and CHD. We examined the effect of bi-weekly nutrition and fitness counseling delivered via smartphone over 12 months. Thirty-four youth, previously diagnosed with CHD and with overweight or obesity, participated in the intervention. They were divided into two groups depending on whether the heart disease required surgical correction (operated, n  = 19) or not (non-operated, n  = 15). Anthropometry, body composition cardiorespiratory exercise capacity, and cardio-metabolic risk factors were assessed at baseline, 6 months, and 12 months. Statistically significant decreases in waist circumference (WC), body mass index z -score, WC z -score, and waist to height ratio z -score were observed at 6 and 12 months in the operated group. A significant linear increase in lean body mass was observed in both groups. The study also had a high retention rate and a low attrition rate. The observed changes in anthropometry were positive with significant improvement to some cardiovascular and metabolic risk indicators. However, this was only observed in the operated group suggesting that other factors, such as perception of condition and self-efficacy, may influence lifestyle behaviors. The results from this pilot study clearly demonstrate the feasibility to perform a larger controlled study on remote lifestyle intervention in children with congenital heart defects and overweight or obesity.

    The complexity of the childhood obesity epidemic requires the application of community-based participatory research (CBPR) in a manner that can transcend multiple communities of stakeholders, including youth, the broader community, and the community of health care providers. To (a) describe participatory processes for engaging youth within context of CBPR and broader community, (b) share youth-engaged research findings related to the use of digital communication and implications for adolescent obesity intervention research, and (c) describe and discuss lessons learned from participatory approaches. CBPR principles and qualitative methods were synergistically applied in a predominantly African American part of the city that experiences major obesity-related issues. A Youth Research Advisory Board was developed to deeply engage youth in research that was integrated with other community-based efforts, including an academic-community partnership, a city-wide obesity coalition, and a primary care practice research network. Volunteers from the youth board were trained to apply qualitative methods, including facilitating focus group interviews and analyzing and interpreting data with the goal of informing a primary care provider-based obesity reduction intervention. The primary results of these efforts were the development of critical insights about adolescent use of digital communication and the potential importance of messaging, mobile and computer apps, gaming, wearable technology, and rapid changes in youth communication and use of digital technology in developing adolescent nutrition and physical activity health promotion. The youth led work helped identify key elements for a digital communication intervention that was sensitive and responsive to urban youth. Many valuable lessons were also learned from 3 years of partnerships and collaborations, providing important insights on applying CBPR with minority youth populations.

    The incidence of obesity and overweight has reached epidemic proportions in the developed world as well as in those countries transitioning to first world economies, and this represents a major global health problem. Concern is rising over the rapid increases in childhood obesity and metabolic disease that will translate into later adult obesity. Although an obesogenic nutritional environment and increasingly sedentary lifestyle contribute to our risk of developing obesity, a growing body of evidence links early life nutritional adversity to the development of long-term metabolic disorders. In particular, the increasing prevalence of maternal obesity and excess maternal weight gain has been associated with a heightened risk of obesity development in offspring in addition to an increased risk of pregnancy-related complications. The mechanisms that link maternal obesity to obesity in offspring and the level of gene-environment interactions are not well understood, but the early life environment may represent a critical window for which intervention strategies could be developed to curb the current obesity epidemic. This paper will discuss the various animal models of maternal overnutrition and their importance in our understanding of the mechanisms underlying altered obesity risk in offspring. PMID:21969822

    To improve systems of care to advance implementation of the U.S. Preventive Services Task Force recommendations for childhood obesity treatment (i.e., clinicians offer/refer children with obesity to intensive, multicomponent behavioral interventions of >25 h over 6 to 12 months to improve weight status) and to expand payment for these services. In July 2015, 43 cross-sector stakeholders attended a conference supported by the Agency for Healthcare Research and Quality, American Academy of Pediatrics Institute for Healthy Childhood Weight, and The Obesity Society. Plenary sessions presenting scientific evidence and clinical and payment practices were interspersed with breakout sessions to identify consensus recommendations. Consensus recommendations for childhood obesity treatment included: family-based multicomponent behavioral therapy; integrated care model; and multidisciplinary care team. The use of evidence-based protocols, a well-trained healthcare team, medical oversight, and treatment at or above the minimum dose (e.g., >25 h) are critical components to ensure effective delivery of high-quality care and to achieve clinically meaningful weight loss. Approaches to secure reimbursement for evidence-based obesity treatment within payment models were recommended. Continued cross-sector collaboration is crucial to ensure a unified approach to increase payment and access for childhood obesity treatment and to scale up training to ensure quality of care. © 2016 The Obesity Society.

    To evaluate the relationships of depression and anxiety symptoms with cardiovascular disease (CVD) risk factors and measures of vascular health in youth. Major depressive disorder and bipolar disorder are considered CVD risk factors in youth. Participants (n = 202) were 8- to 18-year-olds from a cross-sectional study evaluating cardiovascular health across a wide range of body mass index values (normal weight to severe obesity). CVD risk measurement included blood pressure, fasting lipids, glucose, insulin, carotid artery intima-media thickness, compliance and distensibility, brachial artery flow-mediated dilation, carotid-radial artery pulse wave velocity, body fat percentage, and a metabolic syndrome cluster score. Anxiety and depression symptoms were self-reported on the Screen for Child Anxiety Related Disorders and Center for Epidemiological Studies Depression Scale for Children. Two sets of adjustment variables were used in evaluation of differences between those with and without anxiety or depression symptomatology for the CVD risk factor and vascular outcomes. The first set included adjustment for Tanner stage, sex, and race; the second was additionally adjusted for percent body fat. Anxiety was not significantly associated with CVD risk factors or vascular health in either model. Depression was associated with high-density lipoprotein cholesterol, triglycerides, and metabolic syndrome cluster score; these relationships were attenuated when accounting for percent body fat. When accounting for body fat, we found no clear relationship of self-reported depression or anxiety symptoms with CVD risk factors or vascular health in youth. Copyright © 2018 Elsevier Inc.

    To assess the effects of a 12-week gardening, nutrition, and cooking intervention ("LA Sprouts") on dietary intake, obesity parameters, and metabolic disease risk among low-income, primarily Hispanic/Latino youth in Los Angeles. The randomized controlled trial involved four elementary schools [two schools randomized to intervention (172 third-through fifth-grade students); two schools randomized to control (147 third-through fifth-grade students)]. Classes were taught in 90-minute sessions once a week to each grade level for 12 weeks. Data collected at pre- and postintervention included dietary intake via food frequency questionnaire (FFQ), anthropometric measures [BMI, waist circumference (WC)], body fat, and fasting blood samples. LA Sprouts participants had significantly greater reductions in BMI z-scores (0.1-vs. 0.04-point decrease, respectively; P = 0.01) and WC (-1.2 cm vs. no change; P < 0.001). Fewer LA Sprouts participants had the metabolic syndrome (MetSyn) after the intervention than before, while the number of controls with MetSyn increased. LA Sprouts participants had improvements in dietary fiber intake (+3.5% vs. -15.5%; P = 0.04) and less decreases in vegetable intake (-3.6% vs. -26.4%; P = 0.04). Change in fruit intake before and after the intervention did not significantly differ between LA Sprouts and control subjects. LA Sprouts was effective in reducing obesity and metabolic risk. © 2015 The Obesity Society.

    The literature on childhood and adolescent obesity is vast. In addition to producing a general overview, this paper aims to highlight gender differences or similarities, an area which has tended not to be the principal focus of this literature. Databases were searched using the terms 'obesity' and 'child', 'adolescent', 'teenager', 'youth', 'young people', 'sex', 'gender', 'masculine', 'feminine', 'male', 'female', 'boy' and 'girl' (or variations on these terms). In order to limit the potential literature, the main focus is on other reviews, both general and relating to specific aspects of obesity. The findings of genetic studies are similar for males and females, and differences in obesity rates as defined by body mass index are generally small and inconsistent. However, differences between males and females due to biology are evident in the patterning of body fat, the fat levels at which health risks become apparent, levels of resting energy expenditure and energy requirements, ability to engage in certain physical activities and the consequences of obesity for the female reproductive system. Differences due to society or culture include food choices and dietary concerns, overall physical activity levels, body satisfaction and the long-term psychosocial consequences of childhood and adolescent obesity. This review suggests differences between males and females in exposure and vulnerability to obesogenic environments, the consequences of child and adolescent obesity, and responses to interventions for the condition. A clearer focus on gender differences is required among both researchers and policy makers within this field.

    Both cardiorespiratory fitness (CRF) and measures of muscular fitness are associated with metabolic syndrome in adults. However, limited information exists about these relationships in youth with severe obesity who are at increased risk of metabolic dysfunction. The purpose of this study was to examine the relationship between fitness and metabolic health in treatment-seeking youth with obesity. Data for this analysis were collected at the time of baseline visits at a stage 3 pediatric weight management center. Maximal voluntary contractions were obtained by using isometric hand-grip dynamometry, and CRF was obtained from a maximal treadmill test. Resting blood pressure and fasting measures of blood lipids, glucose, and insulin were used to calculate a continuous metabolic syndrome score (cMetS); homeostasis model assessment of insulin resistance (HOMA-IR) was calculated from fasting insulin and glucose. Relationships between measures of fitness and metabolic health were evaluated by using partial correlations adjusted for age. Sixty-nine participants (21 boys, 48 girls) were included in this analysis. Of these, 46% (n = 32) met the criteria for metabolic syndrome. No differences were found between boys and girls for any variable analyzed. Muscular strength was positively associated with cMetS (r = 0.35), though this association weakened after adjustment for body mass index percentile. CRF was inversely associated with homeostasis model assessment of insulin resistance (HOMA-IR) (r = -0.26) and fasting insulin (r = -0.27). Body fat percentage was positively associated with insulin (r = 0.36). No significant relationship was found between CRF and cMetS. Contrary to previous studies, CRF was not associated with metabolic syndrome in this group. Muscular strength, however, was associated with cMetS. Notably, CRF was associated with elevated HOMA-IR, which may be seen as a precursor to metabolic syndrome. These results suggest that CRF and muscular

    Evaluate whether participation in Choose Health: Food, Fun, and Fitness (CHFFF), a hands-on, experiential curriculum aimed at third- to sixth-graders, resulted in improvements in the targeted obesity and chronic disease prevention behaviors. The researchers evaluated CHFFF in low-income youth participating in 2 federal programs in New York State during 2013-2015. Food and activity behaviors were assessed using the Expanded Food and Nutrition Education Program third- through fifth- and sixth- through eighth-grade pre-post surveys, along with 2 sets of added CHFFF-specific items completed by subsamples. Educators trained in CHFFF had youth complete the surveys as they delivered the curriculum, primarily in schools and after-school programs. Paired t tests showed significant (P < .01) positive changes before to after CHFFF education for consumption of vegetables, fruits, sweetened drinks, nutrition label reading, and other food and activity behaviors. Results provide practice-based evidence that CHFFF promotes positive behavior change in participating youth. Copyright © 2017 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    Youth violence is a costly social problem. This study compared the risk and needs of nonviolent youth offenders, with those who had committed violent offenses only (violent only) and those who had committed violent and nonviolent offenses (violent plus) to determine whether violent youth were a different "type" from nonviolent youth. The case files of 3,744 youth offenders (3,327 males and 417 females, between 12 and 18 years old) were retrospectively coded, before official recidivism records were obtained. Multivariate analysis of variance (MANOVA), χ 2 , and Cox regressions were conducted. Violent-plus youth were younger; higher in their total risk and all criminogenic needs; more likely to have several noncriminogenic needs; and at higher risk of any reoffending, violent reoffending, and nonviolent reoffending than nonviolent youth. Violent-only youth had the same total risk and risk of general and violent recidivism as nonviolent offenders but presented different criminogenic and noncriminogenic needs and risk of nonviolent recidivism. Compared to violent-only youth, violent-plus youth were younger, had higher total risk and criminogenic needs on five domains, were more likely to have several noncriminogenic needs, and were at higher risk of all types of reoffending (except sexual reoffending), suggesting subtypes of violent youth offenders. The implication is that nonviolent and violent youth offenders require different dosage and types of intervention.

    Youth violence is among the most serious health threats in the nation today. Violence disproportionately affects young people and people of color. Although the national rates of violent injury and homicide have shown a decline in most regions of the United States over the past 15 years, the rates of violence and related injuries among youth remain unacceptably high. The prevention of youth violence has been a priority of health departments nationwide, including the Cook County Department of Public Health. The goal of this project was to provide key community leaders, social service workers, and nurses within suburban Cook County with educational sessions on Blueprints for Violence Prevention, an initiative to promote evidence-based youth violence prevention programs.

    To compare the prevalence of thinness, overweight and obesity with IOTF and WHO criteria among indigenous school youth from the state of Oaxaca, southern Mexico. The sample included 11 454 indigenous youth (6216 boys, 5238 girls) 6-14 years of age. Heights and weights were measured in 2007 by trained staff. BMIs were calculated and classified as severely thin, moderately thin, normal, overweight or obese using age- and sex-specific IOTF and WHO cut-offs. Prevalence, percentage agreement between classifications, Spearman rank order correlations and Kappa coefficients were calculated. Prevalence of overweight and obesity was higher with WHO than IOTF criteria, while prevalence of severe and moderate thinness did not appreciably differ between criteria. Weight status with the two criteria was discordant in 839 boys (13.5%) and 383 girls (7.3%) and more often for overweight and obesity than thinness. Percentage agreement, correlations and Kappa coefficients were moderate-to-high and were higher in girls than boys. Prevalence of overweight and obesity among indigenous youth in Oaxaca was higher with WHO than IOTF criteria, whereas prevalence of severe and moderate thinness was similar. Differences in estimates for overweight and obesity have implications for surveillance.

    Rising rates of obesity are a public health concern in every industrialized country. This study investigates the relationship between obesity and health care expenditure in Australia, where the rate of obesity has tripled in the last three decades. Now one in four Australians is considered obese, defined as having a body mass index (BMI, kg/m(2)) of 30 or over. The analysis is based on a random sample survey of over 240,000 adults aged 45 and over that is linked at the individual-level to comprehensive administrative health care claims for the period 2006-2009. This sub-population group has an obesity rate that is nearly 30% and is a major consumer of health services. Relative to the average annual health expenditures of those with normal weight, we find that the health expenditures of those with a BMI between 30 and 35 (obese type I) are 19% higher and expenditures of those with BMI greater than 35 (obese type II/III) are 51% higher. We find large and significant differences in all types of care: inpatient, emergency department, outpatient and prescription drugs. The obesity-related health expenditures are higher for obese type I women than men, but in the obese type II/III state, obesity-related expenditures are higher for men. When we stratify further by age groups, we find that obesity has the largest impact among men over age 75 and women aged 60-74 years old. In addition, we find that obesity impacts health expenditures not only through its link to chronic diseases, but also because it increases the cost of recovery from acute health shocks.

    Context Research across four decades has produced numerous empirically-tested evidence-based psychotherapies (EBPs) for youth psychopathology, developed to improve upon usual clinical interventions. Advocates argue that these should replace usual care; but do the EBPs produce better outcomes than usual care? Objective This question was addressed in a meta-analysis of 52 randomized trials directly comparing EBPs to usual care. Analyses assessed the overall effect of EBPs vs. usual care, and candidate moderators; multilevel analysis was used to address the dependency among effect sizes that is common but typically unaddressed in psychotherapy syntheses. Data Sources The PubMed, PsychINFO, and Dissertation Abstracts International databases were searched for studies from January 1, 1960 – December 31, 2010. Study Selection 507 randomized youth psychotherapy trials were identified. Of these, the 52 studies that compared EBPs to usual care were included in the meta-analysis. Data Extraction Sixteen variables (participant, treatment, and study characteristics) were extracted from each study, and effect sizes were calculated for all EBP versus usual care comparisons. Data Synthesis EBPs outperformed usual care. Mean effect size was 0.29; the probability was 58% that a randomly selected youth receiving an EBP would be better off after treatment than a randomly selected youth receiving usual care. Three variables moderated treatment benefit: Effect sizes decreased for studies conducted outside North America, for studies in which all participants were impaired enough to qualify for diagnoses, and for outcomes reported by people other than the youths and parents in therapy. For certain key groups (e.g., studies using clinically referred samples and diagnosed samples), significant EBP effects were not demonstrated. Conclusions EBPs outperformed usual care, but the EBP advantage was modest and moderated by youth, location, and assessment characteristics. There is room for

  8. The obesity epidemic in children and adults: current evidence and research issues.

    PubMed

    Flegal, K M

    1999-11-01

    The term "epidemic" of obesity implies that obesity is a characteristic of populations, not only of individuals. The purpose of this paper is to review evidence on obesity in populations and to identify future research issues. To examine recent increases in the population prevalence of overweight or obesity, a literature search was undertaken. Trends in overweight or obesity among adults showed considerable variability internationally. Some countries, including Canada, Finland (men), New Zealand, the United Kingdom, the United States, and Western Samoa showed large increases in prevalence (>5 percentage points), whereas several other countries showed smaller or no increases. Overweight is also increasing among children and adolescents, at least in some countries. It is not clear what the expected prevalence of overweight or obesity might be in the current environment, and these findings may be most usefully viewed as shifts in the distribution of a population characteristic. The reasons for these shifts are not clear. The health implications of these shifts are also not clear, in part because trends in cardiovascular risk factors do not always parallel trends in obesity. Of the classic epidemiologic triad of host, agent, and environment, the environment has often received the least attention. The economic, social, and cultural factors that influence the distribution of body mass index in a population are not well understood. Future research needs include continued monitoring of trends in obesity and in related health conditions and observational studies to examine the causes of these trends. Public health research should aim at defining realistic goals and strategies to improve health in an environment conducive to high levels of overweight and obesity.

    Increasing globally, particularly in children, obesity is a serious public health issue and risk factor for overweight and metabolic disease in later life. Both in experimental animal and human studies, advances in gene sequencing technologies have yielded intriguing possibilities for the role of the gut microbiome in later development of overweight status. Before translating study findings into practice, we must first reconcile inconsistencies between animal experimentation, and human adult and infant studies. Recent evidence for associations with gut microbiota and infant weight gain or child weight status, implicate Bacteroides and Lactobacillus species. Dietary manipulation with human milk and pre/probiotic formulations holds promise for preventing obesity. PMID:25835047

    While generalized cerebral atrophy and neurodegenerative change following traumatic brain injury (TBI) is well recognized in adults, it remains comparatively understudied in the pediatric population, suggesting that research should address the potential for neurodegenerative change in children and youth following TBI. This focused review examines original research findings documenting evidence for neurodegenerative change following TBI of all severities in children and youth. Our relevant inclusion and exclusion criteria identified a total of 16 articles for review. Taken together, the studies reviewed suggest there is evidence for long-term neurodegenerative change following TBI in children and youth. In particular both cross-sectional and longitudinal studies revealed volume loss in selected brain regions including the hippocampus, amygdala, globus pallidus, thalamus, periventricular white matter, cerebellum, and brain stem as well as overall decreased whole brain volume and increased CSF and ventricular space. Diffusion Tensor Imaging (DTI) studies also report evidence for decreased cellular integrity, particularly in the corpus callosum. Sensitivity of the hippocampus and deep limbic structures in pediatric populations are similar to findings in the adult literature and we consider the data supporting these changes as well as the need to investigate the possibility of neurodegenerative onset in childhood associated with mild traumatic brain injury (mTBI).

  11. Anaesthetic management of obese parturients: what is the evidence supporting practice guidelines?

    Increasing rates of obesity in western populations present management difficulties for clinicians caring for obese pregnant women. Various governing bodies have published clinical guidelines for the care of obese parturients. These guidelines refer to two components of anaesthetic care: anaesthetic consultation in the antenatal period for women with a body mass index (BMI) ≥ 40 kg/m 2 and the provision of early epidural analgesia in labour. These recommendations are based on the increased incidence of obstetric complications and the predicted risks and difficulties in providing anaesthetic care. The concept behind early epidural analgesia is logical-site the epidural early, use it for surgical anaesthesia and avoid general anaesthesia if surgery is required. Experts support this recommendation, but there is weak supporting evidence. It is known that the management of labour epidurals in obese women is complicated and that women with extreme obesity require higher rates of general anaesthesia. Anecdotally, anaesthetists view and apply the early epidural recommendation inconsistently and the acceptability of early epidural analgesia to pregnant women is variable. In this topic review, we critically appraise these two practice recommendations. The elements required for effective implementation in multidisciplinary maternity care are considered. We identify gaps in the current literature and suggest areas for future research. While prospective cohort studies addressing epidural extension ('top-up') in obese parturients would help inform practice, audit of local practice may better answer the question "is early epidural analgesia beneficial to obese women in my practice?".

    One of the most commonly measured markers of inflammation in clinical settings is C-reactive protein (CRP). The purpose of this meta-analysis was to examine the evidence for the effectiveness of physical exercise interventions on modifying the levels of serum CRP in children and adolescents with excess of weight. Two independent reviewers assessed articles from seven databases. Studies were limited to physical exercise interventions in children and adolescents diagnosed as overweight or obese, and including a comparison control group. Weighted mean difference (WMD) was calculated using random-effects model and potential moderators were explored (i.e., weight status, ages, duration of study, frequency of exercise per week, and duration of session). The heterogeneity of the studies was estimated using Cochran's Q-statistic and I(2). Nine randomized controlled trials met the inclusion criteria (n = 427 youths). Overall, results suggest a nonsignificant trend toward a reduction CRP levels (WMD = -0.72 mg/l; 95% confidence interval: -1.52 to 0.08; P = 0.077). Also, there were not significant moderators of exercise effects on CRP. These results suggest that exercise programs in children and adolescents not mitigate the inflammatory effects of excess weight, although there was a trend toward reduction.

    Seasonality in youth suicide has been speculated to be associated with the school calendar, as it tends to increase at the beginning of the academic year or after a long break, but robust empirical evidence remains scarce. We examined the nationwide death records in the Vital Statistics of Japan to investigate the seasonal patterns of suicide among youth. Our data set included 108 968 suicides by individuals who died at 6-26 years of age between 1974 and 2014 in Japan. The daily frequencies of death were plotted against the Japanese school calendar, which has little regional and temporal variations. We also estimated a Poisson regression model to uncover the cyclical patterns of suicide deaths. We found that the frequencies of suicide by middle school students (ages 12-15 years) and high school students (ages 15-18 years) sharply increased around the dates when a school session began in April and September. These tended to be low during school breaks. The results of regression analysis suggested middle school students were more than twice as likely to die by suicide when the summer break ended and the second semester began, compared with the baseline week in July. Similarly, the frequency of suicide for high school students also increased by ∼40% at the end of the summer break. Importantly, no such pattern was found for those aged 18-26 years. Our findings strongly indicate that the cyclical pattern of youth suicide is closely related to the school calendar. Published by the BMJ Publishing Group Limited.

    Increased adiposity increases leptin and decreases adiponectin concentrations, resulting in an increased leptin:adiponectin ratio (LAR). In adults, components of the metabolic syndrome and other cardiometabolic risk factors, what we classify here as "metabolic dysfunction," are associated with both a high LAR and a history of being breast-fed. The relation among breast-feeding, LAR, and degree of metabolic dysfunction in obese youth is unknown. The purpose of our pilot study was to explore this relation and estimate the effect size of the relations to determine the sample size needed to power future prospective studies. We obtained fasting levels of leptin, adiponectin, lipids, insulin, and glucose from obese youth (aged 8-17 years). Weight, height, waist circumference, blood pressure, and breast-feeding history also were assessed. Of 96 participants, 78 were breast-fed as infants, 54% of whom were breast-fed for >6 months. Wide variation was observed in LARs among children who were and were not breast-fed (>100% coefficient of variation). Overall, prevalence of metabolic dysfunction in the cohort was 94% and was not proven to be associated with higher LAR. In this cohort of obese youth, we found a high prevalence of breast-feeding, metabolic dysfunction, and wide variation in the LARs. Based on the effect size estimated, future studies would need to enroll >1500 patients or identify, stratify, and selectively enroll obese patients without metabolic dysfunction to accurately determine whether breast-feeding in infancy influences LARs or metabolic dysfunction among obese youth.

    In the past, interventions aimed at reducing obesity have mainly targeted at weight loss treatment in obese adults, with limited long-term effects. With the increasing number of people being obese and being at risk for obesity, there has been a shift in focus towards prevention of obesity. We conducted a systematic review of the peer-reviewed literature on the efficacy of obesity prevention interventions in adults in order to identify effective interventions and intervention elements. Pubmed, OVID, and Web of Science databases were searched from January 1996 to June 2006. Interventions aimed at primary prevention of weight gain among adults achieved by focusing on dietary intake, physical activity or the combination of both were included. The outcome measure had to be difference in change in body mass index or body weight between the intervention and the control groups. Nine studies were included, five long-term studies (at least 1 year) and four short-term (3 months to 1 year). Seven studies evaluated an intervention that focused on a combination of diet and physical activity to prevent weight gain, one on diet only and one on physical activity only. One dietary intervention (long-term), and three combined dietary and physical activity interventions (one long-term and two short-term) produced significantly positive results at end of follow-up. The two long-term, effective interventions consisted of intensive and long-term intervention implementation, including groups sessions designed to promote behavioural changes. The current evidence of efficacy of obesity prevention interventions is based on a very small number of studies. Some studies showed a positive impact on body mass index or weight status, but there was too much heterogeneity in terms of study design, theoretical underpinning and target population to draw firm conclusions about which intervention approaches are more effective than others. More research is urgently needed to extend the body of evidence.

    Among a group of First Nations youth, this research aimed to obtain objective measures of anthropometry, physical activity (PA) and fitness; to identify any group-level differences by sex, body mass index, waist circumference and body fat categories; to assess the barriers and supports to PA. Youth participated in anthropometric measures (BMI, waist circumference, body fat percentage), PA assessment (3 days of accelerometry) and fitness testing (guided by the Canadian Physical Activity, Fitness and Lifestyle Approach). Barriers and supports were assessed via environmental scan and focus groups. Descriptive statistics were compared to reference data. Group differences by sex, BMI status, waist circumference and body fat categories were tested using Mann-Whitney U and Chi square tests (p ≤ 0.05). Qualitative data were assembled into one file and coded manually for categories and themes. Seventy-two youth (12.1 ± 1.1 years, 61.1% male) participated in at least one measure; 36 completed the accelerometry. Sixty-three percent were overweight or obese, 51% were abdominally obese and 21% had excess body fat. Most (86.1%) met Canada's PA guidelines. Boys were more active than girls (p = 0.025) and had greater cardiorespiratory endurance (p = 0.003). Overweight, obese, or abdominally obese youth had lower cardiorespiratory endurance than normal weight youth (p < 0.001). Barriers and supports fell under the main themes: motivation, role models, personnel and facilities, environment and programs. Based on this assessment, youth in this community are active, but not sufficiently physically fit, especially among those affected by obesity and abdominal obesity. The findings, in addition to the numerous barriers to PA, support the community's desire for school-based PA programming.

    Overweight and obesity in children and adolescents is often accompanied by obesity-related comorbidities. An integrative review of the literature was performed to create a comprehensive algorithm to help primary care providers manage the common comorbidities associated with childhood overweight and obesity. The Cumulative Index to Nursing and Allied Health Literature, ProQuest Nursing and Allied Health Source, and PubMed databases were searched. Evidence from 2002 to present was reviewed. Guidelines and algorithms from the American Academy of Pediatrics, National Association of Pediatric Nurse Practitioners, American Heart Association, American Diabetes Association, Centers for Disease Control and Prevention, National Heart, Lung, and Blood Institute, Agency for Healthcare and Research Quality, U.S. Department of Health and Human Services, and the International Diabetes Federation were also reviewed. Key information was extracted and data sources ranked according to the Polit and Beck evidence hierarchy. Highest level evidence guided the selection and development of recommendations to formulate a comprehensive resource for the recognition and management of pediatric hypertension, sleep apnea, vitamin D deficiency, nonalcoholic fatty liver disease, dyslipidemia, thyroid disease, diabetes mellitus, insulin resistance, metabolic syndrome, and polycystic ovarian syndrome. The Childhood Overweight and Obesity Comorbidities Resource provides a consistent, convenient point-of-care reference to help primary care providers improve pediatric health outcomes. ©2016 American Association of Nurse Practitioners.

  19. Resolved: There is sufficient scientific evidence that decreasing sugar-sweetened beverage consumption will reduce the prevalence of obesity and obesity-related diseases

    Sugar-sweetened beverages (SSBs) are the single largest source of added sugar and the top source of energy intake in the US diet. In this review, we evaluate whether there is sufficient scientific evidence that decreasing SSB consumption will reduce the prevalence of obesity and its related diseases. Since prospective cohort studies address dietary determinants of long-term weight gain and chronic diseases, whereas randomized controlled trials (RCTs) typically evaluate short-term effects of specific interventions on weight change, both types of evidence are critical in evaluating causality. Findings from well-powered prospective cohorts have consistently shown a significant association, established temporality, and demonstrated a direct dose-response relationship between SSB consumption and long-term weight gain and risk of type 2 diabetes (T2D). A recently published meta-analysis of RCTs commissioned by the World Health Organization (WHO) found that decreased intake of added sugars significantly reduced body weight (0.80 kg, 95% CI 0.39 to 1.21; P<0.001), whereas increased sugar intake led to a comparable weight increase (0.75 kg, 0.30 to 1.19; P=0.001). A parallel meta-analysis of cohort studies also found that higher intake of SSBs among children was associated with 55% (95% CI 32%-82%) higher risk of being overweight or obese compared to those with lower intake. Another meta-analysis of eight prospective cohort studies found that 1–2 servings/day of SSB intake was associated with a 26% (95% CI 12–41%) greater risk of developing T2D compared to occasional intake (< 1 serving/month). Recently, two large RCTs with a high degree of compliance provided convincing data that reducing consumption of SSBs significantly decreases weight gain and adiposity in children and adolescents. Taken together, the evidence that decreasing SSBs will decrease the risk of obesity and related diseases such as T2D is compelling. Several additional issues warrant further discussion

    2008-01-01

    Background The literature on childhood and adolescent obesity is vast. In addition to producing a general overview, this paper aims to highlight gender differences or similarities, an area which has tended not to be the principal focus of this literature. Methods Databases were searched using the terms 'obesity' and 'child', 'adolescent', 'teenager', 'youth', 'young people', 'sex', 'gender', 'masculine', 'feminine', 'male', 'female', 'boy' and 'girl' (or variations on these terms). In order to limit the potential literature, the main focus is on other reviews, both general and relating to specific aspects of obesity. Results The findings of genetic studies are similar for males and females, and differences in obesity rates as defined by body mass index are generally small and inconsistent. However, differences between males and females due to biology are evident in the patterning of body fat, the fat levels at which health risks become apparent, levels of resting energy expenditure and energy requirements, ability to engage in certain physical activities and the consequences of obesity for the female reproductive system. Differences due to society or culture include food choices and dietary concerns, overall physical activity levels, body satisfaction and the long-term psychosocial consequences of childhood and adolescent obesity. Conclusion This review suggests differences between males and females in exposure and vulnerability to obesogenic environments, the consequences of child and adolescent obesity, and responses to interventions for the condition. A clearer focus on gender differences is required among both researchers and policy makers within this field. PMID:18194542

    A community's readiness for change is a precursor to the effective application of evidence-based practices for health promotion. Research is lacking regarding potential strategies to improve readiness to address obesity-related health issues in underserved communities. This case study describes SaludABLEOmaha, an initiative to increase readiness of residents in a Midwestern Latino community to address obesity and adopt healthy lifestyles. SaludABLEOmaha emphasized 2 core approaches, youth activism and collaboration among public and private institutions, which we applied to planning and implementing tactics in support of 3 interconnected strategies: 1) social marketing and social media, 2) service learning in schools (ie, curricula that integrate hands-on community service with instruction and reflection), and 3) community and business engagement. Following the Community Readiness Model protocol (http://triethniccenter.colostate.edu/communityReadiness.htm), structured interviews were conducted with community leaders and analyzed before and 2.5 years after launch of the program. The community increased in readiness from stage 3 of the Community Readiness Model, "vague awareness," at baseline to stage 5, "preparation," at follow-up. SaludABLEOmaha improved community readiness (eg, community knowledge, community climate), which probably contributed to the observed increase in readiness to address obesity through healthy lifestyle. Community mobilization approaches such as youth activism integrated with social marketing and social media tactics can improve community responsiveness to obesity prevention and diminish health disparities.

    We examined sexual orientation disparities in physical activity, sports involvement, and obesity among a population-based adolescent sample. We analyzed data from the 2012 Dane County Youth Assessment for 13,933 students in grades 9 through 12 in 22 Wisconsin high schools. We conducted logistic regressions to examine sexual orientation disparities in physical activity, sports involvement, and body mass index among male and female adolescents. When we accounted for several covariates, compared with heterosexual females, sexual minority females were less likely to participate in team sports (adjusted odds ratio [AOR] = 0.44; 95% confidence interval [CI] = 0.37, 0.53) and more likely to be overweight (AOR = 1.28; 95% CI = 1.02, 1.62) or obese (AOR = 1.88; 95% CI = 1.43, 2.48). Sexual minority males were less likely than heterosexual males to be physically active (AOR = 0.62; 95% CI = 0.46, 0.83) or to participate in team sports (AOR = 0.26; 95% CI = 0.20, 0.32), but the 2 groups did not differ in their risk of obesity. Sexual orientation health disparities in physical activity and obesity are evident during adolescence. Culturally affirming research, interventions, and policies are needed for sexual minority youths.

    2008-05-01

    This review seeks to examine the effectiveness of school-based programs for reducing childhood overweight or obesity. A systematic review of the research literature published since 1990 was conducted to identify experimental or quasi-experimental school-based curricular or environmental preventive interventions, with evaluation>or=6 months after baseline, which reported outcomes in terms of a measure of overweight. Fourteen studies were identified, including one involving a nutrition-only program, two physical activity promotion interventions and eleven studies combining nutrition and physical activity components. Most studies (n=10) offered weak (grade 2) quality evidence. One study offered strong (grade 4) evidence reducing the odds ratio for overweight in girls only, while four grade 2 studies reported significant improvements in BMI or at-risk-for overweight or overweight prevalence in boys, girls, or both. Twelve studies reported significant improvement in at least one measure of dietary intake, physical activity, and/or sedentary behavior. Our ability to draw strong conclusions as to the efficacy of school-based obesity prevention programs is limited by the small number of published studies and by methodological concerns. Qualitative analysis suggests programs grounded in social learning may be more appropriate for girls, while structural and environmental interventions enabling physical activity may be more effective for boys. High-quality evaluation protocols should be considered essential components of future programs.

    Objectives To improve systems of care to advance implementation of the U.S. Preventive Services Task Force recommendations for childhood obesity treatment (i.e. clinicians offer/refer children with obesity to intensive, multicomponent behavioral interventions of >25 hours over 6–12 months to improve weight status) and to expand payment for these services. Methods In July 2015, forty-three cross-sector stakeholders attended a conference supported by the Agency for Healthcare Research and Quality, American Academy of Pediatrics Institute for Healthy Childhood Weight, and The Obesity Society. Plenary sessions presenting scientific evidence and clinical and payment practices were interspersed with breakout sessions to identify consensus recommendations. Results Consensus recommendations for childhood obesity treatment included: family-based multicomponent behavioral therapy; integrated care model; and multi-disciplinary care team. The use of evidence-based protocols, a well-trained healthcare team, medical oversight, and treatment at or above the minimum dose (e.g. >25 hours) are critical components to ensure effective delivery of high-quality care and to achieve clinically meaningful weight loss. Approaches to secure reimbursement for evidence-based obesity treatment within payment models were recommended. Conclusion Continued cross-sector collaboration is crucial to ensure a unified approach to increase payment and access for childhood obesity treatment and to scale-up training to ensure quality of care.

    2010-12-01

    Within the field of evidence-based practice, a process termed 'evidence mapping' is emerging as a less exhaustive yet systematic and replicable methodology that allows an understanding of the extent and distribution of evidence in a broad clinical area, highlighting both what is known and where gaps in evidence exist. This article describes the general principles of mapping methodology by using illustrations derived from our experience conducting an evidence map of interventions for youth mental-health disorders. Evidence maps are based on an explicit research question relating to the field of enquiry, which may vary in depth, but should be informed by end-users. The research question then drives the search for, and collection of, appropriate studies utilizing explicit and reproducible methods at each stage. This includes clear definition of components of the research question, development of a thorough and reproducible search strategy, development of explicit inclusion and exclusion criteria, and transparent decisions about the level of information to be obtained from each study. Evidence mapping is emerging as a rigorous methodology for gathering and disseminating up-to-date information to end-users. Thoughtful planning and assessment of available resources (e.g. staff, time, budget) are required by those applying this methodology to their particular field of clinical enquiry given the potential scope of the work. The needs of the end-user need to be balanced with available resources. Information derived needs to be effectively communicated, with the uptake of that evidence into clinical practice the ultimate aim. © 2010 The Authors.

    There is growing evidence that the experience of being ostracized can impair individuals' abilities to self-regulate, which in turn, leads to negative health behaviors, such as increased unhealthy eating. Research has focused on adults, but deficits in eating regulation in response to ostracism may be particularly detrimental for overweight or obese youth. This study examines the effects of a brief episode of ostracism on the motivation to eat and food intake of overweight and normal-weight young adolescents (M age=13.6 years). A computerized ball-tossing game (Cyberball) was used to induce ostracism or inclusion. Following the inclusion/ostracism manipulation, all participants completed an operant computer task to earn points exchangeable for portions of food or for time socializing with an unfamiliar peer. Participants' responses for food and their subsequent energy intake were recorded. As hypothesized, ostracized overweight participants responded more for food and had a greater energy intake than overweight participants in the inclusion/control condition; whereas this was not the case for normal-weight participants. These results are important as studies indicate that overweight and obese youth may be at risk of social isolation and peer difficulties. Social adversity, if left unchanged, may increase the difficulty of promoting long-term changes in overweight youths' health behaviors. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Many youth with significant mental health (MH) and/or substance use (SU) difficulties do not receive specialized services. Collaboration between service providers, researchers, and other stakeholders is essential to improve youth service system capacity to provide evidence-based services to meet the complex array of needs of youth. Facilitators and barriers of implementing evidence-based practice have been identified, but few studies provide examples of the processes of collaboration and implementation for youth MH services. This study explicates the design features and implementation processes of a project to improve screening activities in youth services. These processes supported the building of 16 collaborative networks of service providers from diverse youth-serving sectors (e.g., MH, youth justice, child welfare) in urban, rural, suburban, and remote Canadian communities. These cross-sectoral networks implemented an evidence-based practice (screening youth aged 12-24 years for MH and SU problems using the Global Assessment of Individual Needs-Short Screener [GAIN-SS]) across their services. Materials and resources were provided by a centralized research team. Core project components were standardized and adherence to these components was monitored. Over 800 service providers participated in cross-sectoral networks, capacity-building events, joint data analysis, or interpretation and recommendation sessions. Across the 89 participating agencies, service providers for 84% of participating youth implemented the evidence-based practice accurately in accordance with project protocols, with 98% of positive screens reviewed and addressed according to organizational protocols. Service provider feedback is reported. Facilitators, barriers, and implications of promoting implementation of evidence-based practices across sites and sectors are discussed.

    Many programmes for children that involve gardening and nutrition components exist; however, none include experimental designs allowing more rigorous evaluation of their impact on obesity. The objective of this study is to explore the effects of a novel 12-week gardening, nutrition and cooking intervention {'LA Sprouts'} on dietary intake, obesity parameters and metabolic disease risk among low-income, primarily Hispanic/Latino youth in Los Angeles.. This study used a randomized control trial involving four elementary schools [two randomized to intervention {172, 3rd-5th grade students}; two randomized to control {147, 3rd-5th grade students}]. Classes were taught in 90-min sessions once per week for 12 weeks. Data collected at pre-intervention and post-intervention included dietary intake via food frequency questionnaire, anthropometric measures {body mass index, waist circumference}, body fat, and fasting blood samples. LA Sprouts participants compared with controls had significantly greater reductions in body mass index z-scores {-0.1 vs. -0.04, respectively; p = 0.01} and waist circumference {-1.2 vs. 0.1 cm; p < 0.001}. Fewer LA Sprouts participants had the metabolic syndrome after the intervention than before, while controls with metabolic syndrome increased. LA Sprouts participants compared with controls increased dietary fiber intake {+3.4% vs. -16.5%; p = 0.04}. All participants decreased vegetable intake, but decreases were less in LA Sprouts than controls {-3.7% vs. -26.1%; p = 0.04}. Change in fruit intake did not differ between LA Sprouts and controls. LA Sprouts was effective in reducing obesity and metabolic risk; however, additional larger and longer-term studies are warranted. © 2016 World Obesity Federation.

    Obesity-associated chronic diseases persist in Samoan populations in the United States. Samoans and African Americans share cultural similarities such as church affiliation, perceptions of weight and body size, and obesity-related health risks. Adapting an effective energy balance intervention originally designed for African Americans—Body and Soul— might be useful in reducing obesity among U.S. Samoans. To determine potential attractiveness and adaptations, we used aspects of grounded theory to analyze key-informant and focus group interviews with 31 purposively selected Samoans in Hawaii. We incorporated participatory features into the research with Samoan community members conducting parts of the study. From interview narratives, we identified relevant themes from Samoan culture, such as fa’aSamoa or the Samoan way, and specific energy balance activities to include in an obesity and cancer prevention intervention for U.S.-dwelling Samoans. Our findings describe methods to address health disparities by incorporating culturally appropriate health concepts into existing evidence-based interventions. PMID:25212854

  15. Addressing the policy cacophony does not require more evidence: an argument for reframing obesity as caloric overconsumption.

    PubMed

    Shelley, Jacob J

    2012-11-30

    Numerous policies have been proposed to address the public health problem of obesity, resulting in a policy cacophony. The noise of so many policy options renders it difficult for policymakers to determine which policies warrant implementation. This has resulted in calls for more and better evidence to support obesity policy. However, it is not clear that evidence is the solution. This paper argues that to address the policy cacophony it is necessary to rethink the problem of obesity, and more specifically, how the problem of obesity is framed. This paper argues that the frame "obesity" be replaced by the frame "caloric overconsumption", concluding that the frame caloric overconsumption can overcome the obesity policy cacophony. Frames are important because they influence public policy. Understood as packages that define issues, frames influence how best to approach a problem. Consequently, debates over public policy are considered battles over framing, with small shifts in how an issue is framed resulting in significant changes to the policy environment. This paper presents a rationale for reframing the problem of obesity as caloric overconsumption. The frame "obesity" contributes to the policy cacophony by including policies aimed at both energy output and energy input. However, research increasingly demonstrates that energy input is the primary cause of obesity, and that increases in energy input are largely attributable to the food environment. By focusing on policies that aim to prevent increases in energy input, the frame caloric overconsumption will reduce the noise of the obesity policy cacophony. While the proposed frame will face some challenges, particularly industry opposition, policies aimed at preventing caloric overconsumption have a clearer focus, and can be more politically palatable if caloric overconsumption is seen as an involuntary risk resulting from the food environment. The paper concludes that policymakers will be able to make better sense

    We assessed nationwide trends in extreme obesity prevalence and its impact on metabolic syndrome in Korean youth. Data from 19,593 youth (10,271 boys) aged 2-19 were obtained from the Korean National Health and Nutrition Examination Surveys (2001-2014). The prevalence of extreme obesity and the odds ratio of metabolic syndrome were calculated. Questionnaires on body weight perceptions and weight control behaviors were administered. The prevalence of extreme obesity increased significantly among boys (p<0.05). The odds ratios of extreme obesity on metabolic syndrome compared with obesity were 3.781 and 1.979 in boys and girls, respectively. Obese teenage girls with appropriate weight perception attempted to lose weight more frequently than obese teenage boys did. Although the prevalence of childhood obesity in Korea was similar since early 2000s, extreme obesity prevalence has increased, especially among teenage boys. Considering greater morbidity risks, preventing progression to extreme obesity is crucial.

    Objectives Increased adiposity increases leptin and decreases adiponectin concentrations, resulting in an increased leptin:adiponectin ratio (LAR). In adults, components of the metabolic syndrome and other cardiometabolic risk factors, what we classify here as “metabolic dysfunction,” are associated with both a high LAR and a history of being breast-fed. The relation among breast-feeding, LAR, and degree of metabolic dysfunction in obese youth is unknown. The purpose of our pilot study was to explore this relation and estimate the effect size of the relations to determine the sample size needed to power future prospective studies. Methods We obtained fasting levels of leptin, adiponectin, lipids, insulin, and glucose from obese youth (aged 8–17 years). Weight, height, waist circumference, blood pressure, and breast-feeding history also were assessed. Results Of 96 participants, 78 were breast-fed as infants, 54% of whom were breast-fed for >6 months. Wide variation was observed in LARs among children who were and were not breast-fed (>100% coefficient of variation). Overall, prevalence of metabolic dysfunction in the cohort was 94% and was not proven to be associated with higher LAR. Conclusions In this cohort of obese youth, we found a high prevalence of breast-feeding, metabolic dysfunction, and wide variation in the LARs. Based on the effect size estimated, future studies would need to enroll >1500 patients or identify, stratify, and selectively enroll obese patients without metabolic dysfunction to accurately determine whether breast-feeding in infancy influences LARs or metabolic dysfunction among obese youth.

    American Indian youth experience a greater prevalence of obesity compared with the general U.S. population. One avenue to reverse the trend toward increasing obesity prevalence is through promoting physical activity. The goal of this project was to understand tribal youths' current patterns of physical activity behavior and their beliefs and preferences about physical activity. This assessment used a community-based participatory research approach. Sample included 35 Native youth aged 8-18. A Community Advisory Board was created that specifically developed an exercise survey for this assessment to explore physical activity patterns, preferences, and determinants. Twenty-six youth completed the survey. Descriptive statistics were analyzed, exploring differences by age group. Nine youth participated in 2 focus groups. Qualitative data were analyzed with thematic analysis. Youth distinguished between sports and exercise, with each possessing different determinants. Common motivators were friends, coach, and school, and barriers were lack of programs and school or work. None of the youth reported meeting the recommended 60 min of strenuous exercise daily. This tribal academic partnership responded to a tribal concern by developing an exercise survey and conducting focus groups that addressed tribal-specific questions. The results are informing program development.

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

    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.

    Certain subgroups of youth are at high risk for depression and elevated depressive symptoms, and experience limited access to quality mental health care. Examples are socioeconomically disadvantaged, racial/ethnic minority, and sexual minority youth. Research shows that there are efficacious interventions to prevent youth depression and depressive symptoms. These preventive interventions have the potential to play a key role in addressing these mental health disparities by reducing youth risk factors and enhancing protective factors. However, there are comparatively few preventive interventions directed specifically to these vulnerable subgroups, and sample sizes of diverse subgroups in general prevention trials are often too low to assess whether preventive interventions work equally well for vulnerable youth compared to other youth. In this paper, we describe the importance and need for "scientific equity," or equality and fairness in the amount of scientific knowledge produced to understand the potential solutions to such health disparities. We highlight possible strategies for promoting scientific equity, including the following: increasing the number of prevention research participants from vulnerable subgroups, conducting more data synthesis analyses and implementation science research, disseminating preventive interventions that are efficacious for vulnerable youth, and increasing the diversity of the prevention science research workforce. These strategies can increase the availability of research evidence to determine the degree to which preventive interventions can help address mental health disparities. Although this paper utilizes the prevention of youth depression as an illustrative case example, the concepts are applicable to other health outcomes for which there are disparities, such as substance use and obesity.

    Key Points The microbiome has been implicated in the development of obesity.Conventional therapeutic methods have limited effectiveness for the treatment of obesity and prevention of related complications.Gut microbiome transplantation may represent an alternative and effective therapy for the treatment of obesity. Obesity has reached epidemic proportions. Despite a better understanding of the underlying pathophysiology and growing treatment options, a significant proportion of obese patients do not respond to treatment. Recently, microbes residing in the human gastrointestinal tract have been found to act as an “endocrine” organ, whose composition and functionality may contribute to the development of obesity. Therefore, fecal/gut microbiome transplantation (GMT), which involves the transfer of feces from a healthy donor to a recipient, is increasingly drawing attention as a potential treatment for obesity. Currently the evidence for GMT effectiveness in the treatment of obesity is preliminary. Here, we summarize benefits, procedures, and issues associated with GMT, with a special focus on obesity.

    The ongoing epidemics of obesity is one main health concern of the present time. Overeating in some obese individuals shares similarities with the loss of control and compulsive behavior observed in drug-addicted subjects, suggesting that obesity may involve food addiction. Here, we review the contributions provided by the use of positron emission tomography to the current understanding of the cerebral control of obesity and food intake in humans. The available studies have shown that multiple areas in the brain are involved with the reward properties of food, such as prefrontal, orbitofrontal, somatosensory cortices, insula, thalamus, hypothalamus, amygdala, and others. This review summarizes the current evidence, supporting the concepts that i) regions involved in the somatosensory response to food sight, taste, and smell are activated by palatable foods and may be hyperresponsive in obese individuals, ii) areas controlling executive drive seem to overreact to the anticipation of pleasure during cue exposure, and iii) those involved in cognitive control and inhibitory behavior may be resistant to the perception of reward after food exposure in obese subjects. All of these features may stimulate, for different reasons, ingestion of highly palatable and energy-rich foods. Though these same regions are similarly involved in drug abusers and game-addicted individuals, any direct resemblance may be an oversimplification, especially as the heterogeneities between studies and the prevalent exclusion of sensitive groups still limit a coherent interpretation of the findings. Further work is required to comprehensively tackle the multifaceted phenotype of obesity and identify the role of food dependency in its pathophysiology. Copyright © 2012 S. Karger GmbH, Freiburg.

    Type 2 diabetes has increased in prevalence among youth, paralleling the increase in pediatric obesity. Helping youth achieve energy balance by changing diet and physical activity behaviors should decrease the risk for type 2 diabetes and obesity. Goal setting and goal review are critical components of behavior change. Theory-informed video games that emphasize development and refinement of goal setting and goal review skills provide a method for achieving energy balance in an informative, entertaining format. This article reports alpha-testing results of early versions of theory-informed goal setting and reviews components of two diabetes and obesity prevention video games for preadolescents. Two episodes each of two video games were alpha tested with 9- to 11-year-old youth from multiple ethnic groups. Alpha testing included observed game play followed by a scripted interview. The staff was trained in observation and interview techniques prior to data collection. Although some difficulties were encountered, alpha testers generally understood goal setting and review components and comprehended they were setting personal goals. Although goal setting and review involved multiple steps, youth were generally able to complete them quickly, with minimal difficulty. Few technical issues arose; however, several usability and comprehension problems were identified. Theory-informed video games may be an effective medium for promoting youth diabetes and obesity prevention. Alpha testing helps identify problems likely to have a negative effect on functionality, usability, and comprehension during development, thereby providing an opportunity to correct these issues prior to final production.

    Who pays the healthcare costs associated with obesity? Among workers, this is largely a question of the incidence of the costs of employer-sponsored coverage. Using data from the National Longitudinal Survey of Youth and the Medical Expenditure Panel Survey, we find that the incremental healthcare costs associated with obesity are passed on to obese workers with employer-sponsored health insurance in the form of lower cash wages. Obese workers without employer-sponsored insurance do not have a wage offset relative to their non-obese counterparts. A substantial part of the lower wages among obese women attributed to labor market discrimination can be explained by their higher health insurance premiums. PMID:19433210

    To explore the role of MTNR1B rs10830963 and G6PC2 rs560887 variants in the pathogenesis of impaired fasting glucose (IFG) in obese adolescents. A total of 346 Caucasians, 218 African-Americans, and 217 Hispanics obese children and adolescents underwent an oral glucose tolerance test (OGTT) and 518 underwent the evaluation of insulin secretion by the oral minimal model (OMM). Also, 274 subjects underwent a second OGTT after 3.0 ± 2.1 years. The MTNR1B rs10830963 variant was associated with higher fasting glucose levels and lower dynamic beta-cell response in Caucasians and Hispanics (P < 0.05) and conferred an increased risk of showing IFG to Caucasians (P = 0.05), African-Americans (P = 0.0066), and Hispanics (P = 0.024). Despite the association between the G6PC2 rs560887 and higher fasting glucose levels (P < 0.05), there was no association between this variant and IFG at baseline or at follow-up (all P > 0.10). It has been shown for the first time in obese youth that the MTNR1B variant is associated with an increased risk of IFG. © 2015 The Obesity Society.

    OBJECTIVE The shape of the glucose response curve during an oral glucose tolerance test (OGTT), monophasic versus biphasic, identifies physiologically distinct groups of individuals with differences in insulin secretion and sensitivity. We aimed to verify the value of the OGTT-glucose response curve against more sensitive clamp-measured biomarkers of type 2 diabetes risk, and to examine incretin/pancreatic hormones and free fatty acid associations in these curve phenotypes in obese adolescents without diabetes. RESEARCH DESIGN AND METHODS A total of 277 obese adolescents without diabetes completed a 2-h OGTT and were categorized to either a monophasic or a biphasic group. Body composition, abdominal adipose tissue, OGTT-based metabolic parameters, and incretin/pancreatic hormone levels were examined. A subset of 106 participants had both hyperinsulinemic-euglycemic and hyperglycemic clamps to measure in vivo insulin sensitivity, insulin secretion, and β-cell function relative to insulin sensitivity. RESULTS Despite similar fasting and 2-h glucose and insulin concentrations, the monophasic group had significantly higher glucose, insulin, C-peptide, and free fatty acid OGTT areas under the curve compared with the biphasic group, with no differences in levels of glucagon, total glucagon-like peptide 1, glucose-dependent insulinotropic polypeptide, and pancreatic polypeptide. Furthermore, the monophasic group had significantly lower in vivo hepatic and peripheral insulin sensitivity, lack of compensatory first and second phase insulin secretion, and impaired β-cell function relative to insulin sensitivity. CONCLUSIONS In obese youth without diabetes, the risk imparted by the monophasic glucose curve compared with biphasic glucose curve, independent of fasting and 2-h glucose and insulin concentrations, is reflected in lower insulin sensitivity and poorer β-cell function, which are two major pathophysiological biomarkers of type 2 diabetes in youth.

    We use National Longitudinal Survey of Youth (NLSY) data to examine the effects of obesity on wages by gender. Sample means indicate that both men and women experience a persistent obesity wage penalty over the first two decades of their careers. We then control for a standard set of socioeconomic and familial variables but find that standard covariates do not explain why obese workers experience persistent wage penalties. This suggests that other variables -- including job discrimination, health-related factors and/or obese workers' behavior patterns -- may be the channels through which obesity adversely affects wages. The study closes with a discussion of the public policy implications suggested by these findings.

    The purpose of this article is to provide a review of the existing literature for the comanagement of depression and obesity in the pediatric population. A review of the current literature was conducted using EBSCOhost and EMBASE to identify evidence and recommendations for the comanagement of depression and obesity among children and adolescents (aged 2-18 years). Additional search criteria included peer-reviewed, English language-only full-text articles published before August 2015. Multiple factors contribute to and influence the interplay of obesity and depression in the pediatric population. These 2 chronic conditions are affected by multiple factors, including the roles of the family, school, health care practitioners, and access to health care. In addition, there are no formal recommendations for the treatment of depression in the setting of obesity for pediatric or adult populations, and there is only medication approved by the Food and Drug Administration (orlistat) for the treatment of obesity in the adolescent population. Bariatric surgery may play a role in some adolescents, but larger and long-term clinical studies with the use of therapeutic agents in conjunction with lifestyle modification need to be conducted to support this. The interrelatedness of these 2 separate diseases is not well understood; the presence of 1 of the diseases clearly contributes to the manifestation of the other and likely to the ability to treat the other disease. Current focus is on modifying behavior to decrease weight. Weight loss is associated with improvement in depressive symptoms but may not be adequate to treat depression. Copyright © 2015.

    The objective of this study was to examine the independent and combined association of physical activity and body mass index (BMI) with blood pressure in youth. Youth aged 8-18 years from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) with BMI, blood pressure, and physical activity (accelerometer) were included in the analyses. A total of 2585 subjects (1303 males; 47% of all 8- to 18-year-olds) met these criteria. Obese youth had a systolic blood pressure that was 8 mm Hg higher than normal weight youth. A significant interaction between BMI and physical activity on blood pressure was found (P < .001), and group differences among the BMI/activity groups showed that the 3 obese groups and the overweight/least active group had significantly higher systolic blood pressure than the normal weight/active group across all analyses. The overweight/least active and normal weight/least active groups had significantly higher diastolic blood pressure than the normal weight/active group as well. This study showed a significant independent and combined association of BMI and physical activity with blood pressure in youth. Interventions need to focus on the reduction of fatness/BMI as a way to reduce the cardiovascular risk in youth.

    Hawai'i Youth Services Network (HYSN) was founded in 1980 and is incorporated as a 501(c) (3) organization. HYSN plays a key role in the planning, creation, and funding of local youth services. One of HYSN's focuses is teen pregnancy and sexually transmitted infections (STI) prevention among foster youth. Foster youth are at a greater risk for teen pregnancy and STI due to a variety of complex factors including instability, trauma, and emancipation from the foster care system. This article highlights how HYSN is leveraging both federal and local funding, as well as other resources, in order to implement an evidence-based teen pregnancy and STI prevention program adapted for foster youth.

    2013-01-01

    Chronic inflammation is a characteristic of obesity and is associated with accompanying insulin resistance, a hallmark of type 2 diabetes mellitus (T2DM). Although proinflammatory cytokines are known for their detrimental effects on adipose tissue function and insulin sensitivity, their beneficial effects in the regulation of metabolism have not drawn sufficient attention. In obesity, inflammation is initiated by a local hypoxia to augment angiogenesis and improve adipose tissue blood supply. A growing body of evidence suggests that macrophages and proinflammatory cytokines are essential for adipose remodeling and adipocyte differentiation. Phenotypes of multiple lines of transgenic mice consistently suggest that proinflammatory cytokines increase energy expenditure and act to prevent obesity. Removal of proinflammatory cytokines by gene knockout decreases energy expenditure and induces adult-onset obesity. In contrast, elevation of proinflammatory cytokines augments energy expenditure and decreases the risk for obesity. Anti-inflammatory therapies have been tested in more than a dozen clinical trials to improve insulin sensitivity and glucose homeostasis in patients with T2DM, and the results are not encouraging. One possible explanation is that anti-inflammatory therapies also attenuate the beneficial effects of inflammation in stimulating energy expenditure, which may have limited the efficacy of the treatment by promoting energy accumulation. Thus, the positive effects of proinflammatory events should be considered in evaluating the impact of inflammation in obesity and type 2 diabetes. PMID:23269411

    The news media has substantial influence on public perceptions of social and health issues. This study conducted a video content analysis to examine portrayals of obese persons in online news reports about obesity. The authors downloaded online news videos about obesity (N = 371) from 5 major news websites and systematically coded visual portrayals of obese and nonobese adults and youth in these videos. The authors found that 65% of overweight/obese adults and 77% of overweight/obese youth were portrayed in a negative, stigmatizing manner across multiple obesity-related topics covered in online news videos. In particular, overweight/obese individuals were significantly more likely than were nonoverweight individuals to be portrayed as headless, with an unflattering emphasis on isolated body parts, from an unflattering rear view of their excess weight, eating unhealthy foods, engaging in sedentary behavior, and dressed in inappropriately fitting clothing. Nonoverweight individuals were significantly more likely to be portrayed positively. In conclusion, obese children and adults are frequently stigmatized in online news videos about obesity. These findings have important implications for public perceptions of obesity and obese persons and may reinforce negative societal weight bias.

    Epidemiological studies suggested that obesity increases the risk of colorectal cancer (CRC). The genetic connection between CRC and obesity is multifactorial and inconclusive. In this study, we hypothesize that the study of shared comorbid diseases between CRC and obesity can offer unique insights into common genetic basis of these two diseases. We constructed a comorbidity network based on mining health data for millions of patients. We developed a novel approach and extracted the diseases that play critical roles in connecting obesity and CRC in the comorbidity network. Our approach was able to prioritize metabolic syndrome and diabetes, which are known to be associated with obesity and CRC through insulin resistance pathways. Interestingly, we found that osteoporosis was highly associated with the connection between obesity and CRC. Through gene expression meta-analysis, we identified novel genes shared among CRC, obesity and osteoporosis. Literature evidences support that these genes may contribute in explaining the genetic overlaps between obesity and CRC.

  16. Carbohydrates and obesity: from evidence to policy in the UK.

    PubMed

    Jebb, Susan A

    2015-08-01

    Carbohydrates provide the major source of energy in the diet and hence the type and amount of carbohydrate consumed is an important consideration for weight control. Recent risk assessments have shown that there is no consistent association between the proportions of energy consumed as carbohydrate and body weight and reinforce the dominance of total energy intake as the primary determinant of body weight. However, they have highlighted evidence that different types of carbohydrate have specific effects on the risk of obesity. Short-term experimental studies suggest that some types of dietary fibre may be linked to increased satiation and cohort studies are supportive of an association between low intakes of fibre-rich, whole-grain foods and weight gain. But these observations are not supported by evidence of effects on body weight in randomised controlled trials, suggesting that high-fibre or whole-grain intake may simply be a marker of a broader dietary pattern. Recent attention has focused on the growing evidence of a positive association between the intake of free sugars and weight gain and particularly the risks linked to consumption of sugar-sweetened beverages (SSB). Given the high population-level intake of free sugars the challenge is to identify actions that will successfully reduce consumption to contribute to reductions in the prevalence of obesity. The present paper considers the range of policy options available, using the Nuffield ladder of intervention to provide a framework for risk management, with a focus on the consumption of SSB. Current policy interventions are largely based around consumer education and encouragement to industry to renovate products to reduce the sugar content of food and drinks and/or reduce portion size, but dietary change has been slow. Further measures, including the use of specific incentives/disincentives may be needed to change consumption patterns, some of which may infringe personal or commercial freedom. For these

    Increasing school-day physical activity through policy and programs is commonly suggested to prevent obesity and improve overall child health. However, strategies that focus on school-day physical activity may not increase total physical activity if youth compensate by reducing physical activity outside of school. Objectively measured, nationally representative physical activity data were used to test the hypothesis that higher school-day physical activity is associated with higher overall daily physical activity in youth. Accelerometer data from 2003-2004/2005-2006 National Health and Nutrition Examination Surveys were analyzed in 2012 to estimate physical activity levels during the school day (8AM-3PM) among youth aged 6-19 years (n=2548). Fixed-effects regressions were used to estimate the impact of changes in school-day minutes of moderate-to-vigorous physical activity (MVPA) on changes in total daily MVPA. Each additional minute of school-day MVPA was associated with an additional 1.14 minutes (95% CI=1.04, 1.24; p<0.001) of total daily MVPA, or 0.14 additional minutes (95% CI=0.04, 0.24; p=0.008) outside the school day, controlling for total daily accelerometer wear time and age, gender, race/ethnicity, and other non-time varying covariates. There were no differences in the effect of school-day MVPA on total MVPA by age group, gender, race/ethnicity, poverty status, or degree of change in MVPA. Higher school-day MVPA was associated with higher daily MVPA among U.S. youth with no evidence for same-day "compensation." Increasing school-based physical activity is a promising approach that can improve total daily physical activity levels of youth. Copyright © 2013 American Journal of Preventive Medicine.

    Obesity is a major cardiovascular risk factor. In Spain, few studies have physically measured height and weight to estimate the magnitude of the problem. The aim of this study was to determine the prevalence of child and adolescent obesity in Spain in 2012. We performed a cross-sectional probability sample of 1018 children, representative of the Spanish population aged between 8 and 17 years old, with objectively measured height and weight, along with other sociodemographic variables. We calculated the prevalence of overweight and obesity according to the criteria of the World Health Organization, the International Obesity Task Force, and the enKid study. In the group aged 8 to 17 years old, the prevalence of overweight and obesity was 26% and 12.6%, respectively; 4 in 10 young people were overweight or obese. Excess weight was found in 45% of the group aged 8 to 13 years and in 25.5% of that aged 14 to 17 years. This cardiovascular risk factor was associated with lower social class and lower educational level. The prevalence of overweight and obesity in children and adolescents in Spain remains high (close to 40%), but has not increased in the last 12 years.

    The problem of substance use among older youth is of great concern, but has received little attention in prevention research. This may be due to the perception that prevention programming is developmentally inappropriate for older youth who are actively experimenting with substances. This project examined the differential effectiveness of youth-driven adaptations of the evidence-based prevention program, keepin' it REAL (KiR). The participating sites included a juvenile justice day program, a homeless shelter, four alternative high schools, low-income housing programs, an LGBTQ youth center, and a youth group on the Texas-Mexico border. In the project's first phase, high risk youth in community settings tailored KiR workbooks and videos to increase the relevance for their peers, older adolescents who are likely to have already initiated drug use. The second phase of the study, discussed here in detail, evaluates the effectiveness of the adapted versions of KiR compared with the original version and a comparison condition. The study employed a quasi-experimental pretest posttest design with a 6-week follow-up. Youth also participated in focus groups. Both qualitative and quantitative data suggest that participants receiving the adapted version of the curriculum experienced greater improvement in acceptance and use of substances than youth in the other two groups.

    Contingency management (CM) interventions, which use operant conditioning principles to encourage completion of target behavioral goals, may be useful for improving adherence to behavioral skills training (BST). Research-to-date has yet to explore CM for weight loss in minority adolescents. To examine the effects of CM in improving adolescent weight loss when added to BST. The study utilized an innovative experimental design that builds upon multiple baseline approaches as recommended by the National Institutes of Health. Six obese African-American youth and their primary caregivers living in Detroit, Michigan, USA. Adolescents received between 4 and 12 weeks of BST during a baseline period and subsequently received CM targeting weight loss. Youth weight. Linear mixed effects modeling was used in the analysis. CM did not directly affect adolescent weight loss above that of BST (p=0.053). However, when caregivers were involved in CM session treatment, contingency management had a positive effect on adolescent weight loss. The estimated weight loss due to CM when caregivers also attended was 0.66 kg/week (p<0.001, [95% CI; -1.96, -0.97]) relative to the baseline trajectory. This study demonstrates application of a novel experimental approach to intervention development and demonstrated the importance of parent involvement when delivering contingency management for minority youth weight loss. Lessons learned from contingency management program implementation are also discussed in order to inform practice.

    Observational studies have indicated that high levels of serum uric acid are associated with the risk of cardiovascular disease. The aim of the present study is to investigate the association of uric acid with individual cardiometabolic risk factors, as well as their degree of clustering, in overweight and moderate obese youth. Three hundred and thirty-three Caucasians of both sexes (149 women), from 5-18 years of age from those who underwent an assessment of overweight/obesity. Anthropometric parameters, office and 24-h blood pressure measurements and metabolic profile, including HDL-cholesterol, triglycerides, insulin, HOMA index and uric acid were assessed. Uric acid was significantly higher in boys than in girls. A positive significant association between uric acid, and office, daytime and night-time SBP, insulin and triglycerides was observed. When boys and girls were grouped by sex-specific uric acid tertiles, a progressive increment was observed in BMI, BMI z-score and waist circumference as well as fasting insulin and HOMA index. In boys, this was also present in office and ambulatory SBP. Likewise, the number of abnormal metabolic risk factors also increases with the uric acid values and the higher the number of metabolic components the higher the uric acid values. Moreover, in a multiple regression analysis, uric acid was significantly related with male sex, waist circumference, both office and night-time SBP and birth weight. The present study found a positive association between uric acid and blood pressure, insulin and triglycerides. As uric acid levels increase there is a relevant clustering of metabolic risk factors, whereas elevated blood pressure is the risk factor less frequently present. Further studies need to assess the mechanistic link between uric acid and the cardiometabolic risk factors.

    Background Type 2 diabetes has increased in prevalence among youth, paralleling the increase in pediatric obesity. Helping youth achieve energy balance by changing diet and physical activity behaviors should decrease the risk for type 2 diabetes and obesity. Goal setting and goal review are critical components of behavior change. Theory-informed video games that emphasize development and refinement of goal setting and goal review skills provide a method for achieving energy balance in an informative, entertaining format. This article reports alpha-testing results of early versions of theory-informed goal setting and reviews components of two diabetes and obesity prevention video games for preadolescents. Method Two episodes each of two video games were alpha tested with 9- to 11-year-old youth from multiple ethnic groups. Alpha testing included observed game play followed by a scripted interview. The staff was trained in observation and interview techniques prior to data collection. Results Although some difficulties were encountered, alpha testers generally understood goal setting and review components and comprehended they were setting personal goals. Although goal setting and review involved multiple steps, youth were generally able to complete them quickly, with minimal difficulty. Few technical issues arose; however, several usability and comprehension problems were identified. Conclusions Theory-informed video games may be an effective medium for promoting youth diabetes and obesity prevention. Alpha testing helps identify problems likely to have a negative effect on functionality, usability, and comprehension during development, thereby providing an opportunity to correct these issues prior to final production.

    The objective of this study was to investigate the associations between potassium and obesity/metabolic syndrome. We identified eight relevant studies and applied meta-analysis, and nonlinear dose-response analysis to obtain the available evidence. The results of the pooled analysis and systematic review indicated that high potassium intake could not reduce the risk of obesity (pooled OR = 0.78; 95% CI: 0.61-1.01), while serum potassium and urinary sodium-to-potassium ratio was associated with obesity. Potassium intake was associated with metabolic syndrome (pooled OR = 0.75; 95% CI: 0.50-0.97). Nonlinear analysis also demonstrated a protective effect of adequate potassium intake on obesity and metabolic syndrome. Adequate intake of fruits and vegetables, which were the major sources of potassium, was highly recommended. However, additional pertinent studies are needed to examine the underlying mechanism.

    Background In South Africa, HIV prevalence among youth aged 15-24 is among the world's highest. Given the urgent need to identify effective HIV prevention approaches, this review assesses the evidence base for youth HIV prevention in South Africa. Methods Systematic, analytical review of HIV prevention interventions targeting youth in South Africa since 2000. Critical assessment of interventions in 4 domains: 1) study design and outcomes, 2) intervention design (content, curriculum, theory, adaptation process), 3) thematic focus and HIV causal pathways, 4) intervention delivery (duration, intensity, who, how, where). Results Eight youth HIV prevention interventions were included; all were similar in HIV prevention content and objectives, but varied in thematic focus, hypothesised causal pathways, theoretical basis, delivery method, intensity and duration. Interventions were school- (5) or group-based (3), involving in- and out-of-school youth. Primary outcomes included HIV incidence (2), reported sexual risk behavior alone (4), or with alcohol use (2). Interventions led to reductions in STI incidence (1), and reported sexual or alcohol risk behaviours (5), although effect size varied. All but one targeted at least one structural factor associated with HIV infection: gender and sexual coercion (3), alcohol/substance use (2), or economic factors (2). Delivery methods and formats varied, and included teachers (5), peer educators (5), and older mentors (1). School-based interventions experienced frequent implementation challenges. Conclusions Key recommendations include: address HIV social risk factors, such as gender, poverty and alcohol; target the structural and institutional context; work to change social norms; and engage schools in new ways, including participatory learning.

    Peer-led interventions may be an effective means of addressing the childhood obesity epidemic; however, few studies have looked at the long-term sustainability of such programs. As part of a multilevel obesity prevention intervention, B’More Healthy Communities for Kids, 16 Baltimore college students were trained as youth-leaders (YLs) to deliver a skill-based nutrition curriculum to low-income African American children (10–14 years old). In April 2015, formative research was used to inform sustainability of the YL program in recreation centers. In-depth interviews were conducted with recreation center directors (n = 4) and the YLs (n = 16). Two focus groups were conducted with YLs (n = 7) and community youth-advocates (n = 10). Barriers to this program included difficulties with transportation, time constraints, and recruiting youth. Lessons learned indicated that improving trainings and incentives to youth were identified as essential strategies to foster continuity of the youth-led program and capacity building. High school students living close to the centers were identified as potential candidates to lead the program. Based on our findings, the initial intervention will be expanded into a sustainable model for implementation, using a train-the-trainer approach to empower community youth to be change agents of the food environment and role models.

    Background A community’s readiness for change is a precursor to the effective application of evidence-based practices for health promotion. Research is lacking regarding potential strategies to improve readiness to address obesity-related health issues in underserved communities. Community Context This case study describes SaludABLEOmaha, an initiative to increase readiness of residents in a Midwestern Latino community to address obesity and adopt healthy lifestyles. Methods SaludABLEOmaha emphasized 2 core approaches, youth activism and collaboration among public and private institutions, which we applied to planning and implementing tactics in support of 3 interconnected strategies: 1) social marketing and social media, 2) service learning in schools (ie, curricula that integrate hands-on community service with instruction and reflection), and 3) community and business engagement. Following the Community Readiness Model protocol (http://triethniccenter.colostate.edu/communityReadiness.htm), structured interviews were conducted with community leaders and analyzed before and 2.5 years after launch of the program. Outcome The community increased in readiness from stage 3 of the Community Readiness Model, “vague awareness,” at baseline to stage 5, “preparation,” at follow-up. Interpretation SaludABLEOmaha improved community readiness (eg, community knowledge, community climate), which probably contributed to the observed increase in readiness to address obesity through healthy lifestyle. Community mobilization approaches such as youth activism integrated with social marketing and social media tactics can improve community responsiveness to obesity prevention and diminish health disparities.

    Although a negative association between obesity and labour market outcomes is commonly reported in many studies, the causal nature of this relationship remains unclear. Using nationally representative longitudinal data from the last six confidential master files (2000/2001-2010/2011) of the National Population Health Survey, we examine the association between obesity and employment participation and earnings among working-age adults in Canada. After controlling for demographic and socioeconomic characteristics, lifestyle factors and time-invariant individual heterogeneity, our results show that obesity is not significantly associated with employment participation but is associated with reduced hourly wage rate and annual income among women by about 4% and 4.5%, respectively. The corresponding results for men show that obesity is associated with about 2% reduction in wage rate and income, but significant at 10% level. However, after controlling for the potential reverse causality bias using the lagged measure of obesity, the effect of obesity on wage rate and income became positive or statistically non-significant. Our findings suggest that obesity is not causally associated with negative labour market outcomes among working-age men in Canada. For working-age women, we find limited evidence of negative labour market outcomes. Copyright © 2015 Elsevier B.V. All rights reserved.

    Obesity and physical inactivity are known to be risk factors for many chronic diseases including hypertension, coronary artery disease, diabetes, and cancer. We sought to explore the association between an indicator of transportation data (Vehicle Miles of Travel, VMT) at the county level as it relates to obesity and physical inactivity in California. Data from the California Health Interview Survey 2001 (CHIS 2001), the US 2000 Census, and the California Department of Transportation were merged to examine ecological correlations between vehicle miles of travel, population density, commute time, and county indicators of obesity and physical inactivity. Obesity was measured by body mass index (BMI). Physical inactivity was based on self-reported behaviors including walking, bicycling, and moderate to vigorous activity. The unit of analysis was the county. Thirty-three counties in California with population size greater than 100,000 persons per county were retained in the analyses. CHIS 2001 statewide obesity prevalence ranged from 11.2% to 28.5% by county. Physical inactivity ranged from 13.4% to 35.7%. Daily vehicle miles of travel ranged from 3.3 million to 183.8 million per county. By rank bivariate correlation, obesity and physical inactivity were significantly associated (p<0.01). Furthermore, by rank analysis of variance, the highest mean rank obesity was associated with the highest rank of VMT (p<0.01). Similar rank patterns were observed between obesity and physical inactivity and commute time. Associations between VMT and physical inactivity were examined but failed to reach statistical significance. This analysis adds to the growing evidence supporting the association between VMT (a measure of automobile transportation) and obesity. An urban design characterized by over dependence on motorized transportation may be related to adverse health effects.

    In several developed countries, as obesity prevalence doubles it has quadrupled for morbid obesity (BMI ≥ 40 kgm -2 ). As more individuals with morbid obesity present for weight loss treatment there is a greater need to understand their dietary habits. No reviews were found in the literature, therefore this systematic review aims to identify and describe the existing evidence on the usual dietary intake of individuals with morbid obesity including those from a general population and those seeking treatment such as weight loss surgery. A literature search of ten databases from 1980 to June 2014 was conducted to identify original research of adults with morbid obesity (aged 18-60 years) that reported a usual dietary intake. Ten studies met all inclusion criteria and reported energy intake, most reported macronutrient composition, two assessed micronutrient intake, and one reported food-based outcomes. Other dietary outcomes were related to surgical intervention. The most plausible energy intake data suggest high intakes, >4000 Kcal/day for those weight stable at the highest levels of morbid obesity (up to BMI 97 kgm -2 ). Fat intakes are also high, around 40% of energy intake and up to 57% for some individuals. Suboptimal intakes of iron and calcium are reported. This review draws attention to a limited evidence base, offers preliminary insight suggesting individuals with morbid obesity are prone to consuming poor quality diets similar to those reported for obese populations, and highlights challenges for future research.

  19. Effectiveness of sugar-sweetened beverages taxes to reduce obesity: evidence brief for policy

    PubMed

    Bascuñán, Josefina; Cuadrado, Cristóbal

    2017-10-25

    The high prevalence of obesity in Chile, along with the increasing consumption of sugary drinks in the country, has made apparent the need to propose fiscal measures, through taxes on specific foods, as a complementary alternative to approach this problem. Since 2014, an additional 5% increase in the tax on sugar-sweetened nonalcoholic beverages has been in effect in Chile, an amount that may be insufficient to produce an impact on obesity levels. The evidence of the effectiveness of fiscal measures upon sugary beverages, in terms of price modification, generally reflects a high transfer of the tax to the final consumers, which is variable according to local conditions. After the analysis of the literature, a sensitivity of the demand to the changes in prices of sugary drinks was evidenced, by means of negative elasticity close to -1, for different groups observed, besides a decrease in the consumption of these products. On the other hand, effects on body weight after the application of these taxes were analyzed by several simulation studies, reporting a decrease on prevalence of obesity between 0.99% and 2.4%. Within the acceptability of a fiscal measure of this nature, there were variable support figures between 36% and 60% among general population. Regarding possible negative effects on employment, an international study even evidenced a rise in the figures for employment in two locations following the application of a tax on sugary drinks. The research showed that there is evidence to support the implementation of a fiscal measure upon sugary beverages in Chile; however, there is a lack of local simulation studies to explore the possible effects and implications of a new tax of this kind in the country. Taxation measures upon foods seem to be both viable and effective alternatives to address the problem of obesity in Chile, but they should be considered as part of an overall strategy with the clear goal of reducing the prevalence of national obesity.

    Despite much effort, obesity prevalence and disease severity continues to worsen. The purpose of this review is to describe the leading government supported food and nutrition interventions and policies to prevent and address obesity in the USA. The review also summarizes obesity interventions and policies that the government plays a role in, but further development is warranted. The government's role in obesity has largely focused on interventions and policies such as national surveillance, obesity education and awareness, grant-based food subsidy programs, zoning for food access, school-based nutrition programs, dietary guidelines, nutrition labeling, and food marketing and pricing policies. The government has played a lesser role in obesity interventions and policies that provide access to evidence-based obesity care to people affected by the disease. Given the magnitude of the obesity epidemic, the government should explore multiple evidence-based interventions and policies across prevention and clinical care.

  1. Sugar-sweetened and artificially-sweetened beverages in relation to obesity risk.

    PubMed

    Pereira, Mark A

    2014-11-01

    The goal of this review was to critically evaluate the scientific evidence in humans on the potential effect of sweetened beverages on weight gain and risk of obesity in youth and adults. Two categories of these beverages were reviewed. Sugar-sweetened beverages (SSBs) include soft drinks, colas, other sweetened carbonated beverages, and fruit drinks with added sugar. Artificially sweetened beverages (ASBs), also referred to as non-nutritive sweetened beverages, are marketed and used as a replacement for SSBs for those who want to reduce sugar and caloric intake. The totality of evidence to date demonstrates a pattern across observational and experimental studies of an increased risk of weight gain and obesity with higher intake of SSBs. However, it remains difficult to establish the strength of the association and the independence from other potentially confounding factors. The primary reason for unclear conclusions regarding the robustness of any effect of SSBs is due to the heterogeneity and methodologic limitations of both observational and experimental studies on this topic. Although some observational studies have suggested that ASBs may cause increased risk of obesity and cardiometabolic diseases, there is no clear mechanism for this pathway, and the epidemiologic studies are highly inconsistent. An important issue with the observational studies on ASBs and obesity or disease risk is reverse causality bias, with higher-quality studies demonstrating this possibility. The field needs higher-quality experimental studies in humans, with relevant direct comparisons between sweetened beverages and their sweetened solid-food alternatives. © 2014 American Society for Nutrition.

    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.

    BACKGROUND Obesity is a major concern among American Indians and Hispanics. The Child Health Initiative for Lifelong Eating and Exercise (CHILE) is an evidence-based intervention to prevent obesity in children enrolled in 16 Head Start (HS) Centers in rural communities. The design and implementation of CHILE are described. METHODS CHILE uses a socio-ecological approach to improve dietary intake and increase physical activity. The intervention includes: a classroom curriculum; teacher and food service training; family engagement; grocery store participation; and health care provider support. RESULTS Lessons learned from CHILE include: the need to consider availability of recommended foods; the necessity of multiple training sessions for teachers and food service; the need to tailor the family events to local needs; consideration of the profit needs of grocery stores; and sensitivity to the time constraints of health care providers. CONCLUSIONS HS can play an important role in preventing obesity in children. CHILE is an example of a feasible intervention that addresses nutrition and physical activity for preschool children that can be incorporated into HS curricula and aligns with HS national performance standards.

    In this article, we review theory and evidence on stigma and minority stress as social/structural determinants of health among lesbian, gay, bisexual, and transgender (LGBT) youth. We discuss different forms of stigma at individual (eg, identity concealment), interpersonal (eg, victimization), and structural (eg, laws and social norms) levels, as well as the mechanisms linking stigma to adverse health outcomes among LGBT youth. Finally, we discuss clinical (eg, cognitive behavioral therapy) and public health (eg, antibullying policies) interventions that effectively target stigma-inducing mechanisms to improve the health of LGBT youth.

    The prevalence of childhood obesity has been increasing but the causes are not fully understood. Recent public health interventions and guidance aiming to reduce childhood obesity have focused on the whole family, as opposed to just the child but there remains a lack of empirical evidence examining this relationship. Using data from the longitudinal Millennium Cohort Study (MCS), we investigate the dynamic relationship between underlying family lifestyle and childhood obesity during early childhood. The MCS interviewed parents shortly after the birth of their child and follow up interviews were carried out when the child was 3, 5 and 7 years. We use a dynamic latent factor model, an approach that allows us to identify family lifestyle, its evolution over time (in this case between birth and 7 years) and its influence on childhood obesity and other observable outcomes. We find that family lifestyle is persistent, 87.43% of families which were above the 95th percentile on the lifestyle distribution, remained above the 95th percentile when the child was 7 years old. Family lifestyle has a significant influence on all outcomes in the study, including diet, exercise and parental weight status; family lifestyle accounts for 11.3% of the variation in child weight by age 7 years. The analysis suggests that interventions should therefore be prolonged and persuasive and target the underlying lifestyle of a family as early as possible during childhood in order to have the greatest cumulative influence. Our results suggest that children from advantaged backgrounds are more likely to be exposed to healthier lifestyles and that this leads to inequalities in the prevalence of obesity. To reduce inequalities in childhood obesity, policy makers should target disadvantaged families and design interventions specifically for these families.

    The Institute of Medicine's Food and Nutrition Board had a productive year, with important expert committee reports on the Supplemental Food Assistance Program, physical fitness, and accelerating obesity prevention efforts that provided grounding for dietary guidance and nutrition policies and programs. This summary describes Food and Nutrition Board activities, including current thinking on dietary reference intakes. The summary also highlights consensus reports on defining and measuring Supplemental Food Assistance Program benefit adequacy and on physical fitness and health outcomes in youth. In addition, current and new activities related to obesity prevention and care are addressed. What do these activities have in common? All adhere to the Institute of Medicine report model by filling gaps and by being analytical, evidence-based, and challenging.

    There is evidence that overweight and obese children tend to remain overweight or obese into adolescence and adulthood. However, little is known about the long-term psychosocial outcomes of childhood overweight and obesity. This study aimed to investigate the course of psychosocial difficulties over a 2-year period for children who were overweight or obese at baseline, and a sample of children who were a healthy weight at baseline. Participants were 212 children aged 8 to 13 years at baseline, who were participating in the Childhood Growth and Development (GAD) Study. Questionnaire and interview measures were used to assess children's self-esteem, depressive symptoms, body image, eating disorder symptoms, experiences with bullying, family satisfaction and quality of life. Linear mixed models were used to consider longitudinal changes in psychosocial variables. Overweight and obese children reported greater psychosocial distress than healthy weight children, and these differences were more pronounced for girls than boys. Weight and psychosocial impairment showed stability from baseline to 2-year follow-up. The results of this study suggest that psychosocial difficulties show considerable stability in childhood, for overweight/obese and healthy weight children. What is Known: • Childhood obesity tracks into adolescence and adulthood. • Physical health problems associated with childhood obesity also persist to adulthood. What is New: • Overweight and obese children are at risk of ongoing psychosocial distress from childhood into early adolescence.

    In paediatric patients, obstructive sleep apnoea is associated with adiposity, especially visceral adiposity. In adults, obstructive sleep apnoea is also associated with a higher prevalence of cardiovascular disease and type 2 diabetes. There are limited and conflicting paediatric studies examining the association between obstructive sleep apnoea and biomarkers of risk for cardiovascular disease and type 2 diabetes in youth. Obstructive sleep apnoea is linked with greater cardiometabolic risk markers in obese adolescents. Fasting insulin and homeostasis model assessment-insulin resistance may be especially linked with obstructive sleep apnoea among obese male Hispanic adolescents. The relationship between obstructive sleep apnoea and cardiometabolic abnormalities in obese adolescents should be considered when evaluating patients found to have obstructive sleep apnoea. Paediatric studies examining the association between obstructive sleep apnoea (OSA) and insulin sensitivity/cardiometabolic risk are limited and conflicting. This study aims to determine if cardiometabolic risk markers are increased among obese youth with obstructive sleep apnoea as compared with their equally obese peers without OSA. We performed a retrospective analysis of 96 patients (age 14.2 ± 1.4 years) who underwent polysomnography for suspected OSA. Fasting lipids, glucose, insulin and haemoglobin A1 c (HbA1 c) were performed as part of routine clinical evaluation. Patients were categorized into two groups by degree of OSA as measured by the apnoea-hypopnoea index (AHI): none or mild OSA (AHI < 5) and moderate or severe OSA (AHI ≥ 5). Despite the similar degrees of obesity, patients with moderate or severe OSA had higher fasting insulin (P = 0.037) and homeostasis model assessment-insulin resistance (HOMA-IR [P = 0.0497]) as compared with those with mild or no OSA. After controlling for body mass index, there was a positive association between the AHI and log

    The encouragement of healthy lifestyles for obesity prevention in young people is a public health priority. The European Youth Tackling Obesity (EYTO) project is a multicentric intervention project with participation from the United Kingdom, Portugal, the Czech Republic and Spain. The general aim of the EYTO project is to improve lifestyles, including nutritional habits and physical activity practice, and to prevent obesity in socioeconomically disadvantaged and vulnerable adolescents. The EYTO project works through a peer-led social marketing intervention that is designed and implemented by the adolescents of each participating country. Each country involved in the project acts independently. This paper describes the "Som la Pera" intervention Spanish study that is part of the EYTO project. In Spain, the research team performed a cluster randomised controlled intervention over 2 academic years (2013-2015) in which 2 high-schools were designated as the control group and 2 high-schools were designated as the intervention group, with a minimum of 121 schoolchildren per group. From the intervention group, 5 adolescents with leadership characteristics, called "Adolescent Challenge Creators" (ACCs), were recruited. These 5 ACCs received an initial 4 h training session about social marketing principles and healthy lifestyle theory, followed by 24 sessions (1.30 h/session) divided in two academic years to design and implement activities presented as challenges to encourage healthy lifestyles among their peers, the approximately 180-200 high-school students in the intervention group. During the design of the intervention, it was essential that the ACCs used the 8 social marketing criteria (customer orientation, behaviour, theory, insight, exchange, competition, segmentation and methods mix). The expected primary outcomes from the Spanish intervention will be as follows: increases in the consumption of fruits and vegetables and physical activity practice along with

    Children classified as overweight or obese and those with disabilities are at a greater risk of not meeting the minimum recommendation of 60 min a day of moderate to vigorous physical activity (PA). Youth with Prader-Willi Syndrome (PWS) appear to participate in less PA compared to nonsyndromal children, likely due to syndrome-related factors. However, description of PA patterns in youth with PWS is lacking. The purpose of this study was to characterize PA in youth with PWS and to compare it to PA in children with nonsyndromal obesity. Twenty-four youth with PWS (ages 8-16 years) and 40 obese children without PWS (OB) (ages 8-11 years) wore accelerometers for eight consecutive days. Data were screened for compliance and classified into PA intensities: sedentary behavior (SED), light (LPA), moderate (MPA), vigorous (VPA) and moderate plus vigorous (MVPA). Youth with PWS spent 19.4% less time in weekly LPA (p=0.007) and 29.8% less time in weekly VPA compared to OB controls (p=0.036). All other intensities were similar between groups. In addition, PWS participated in less LPA and VPA during the weekends compared to OB, and less LPA on weekdays when compared to OB. There was also a trend towards PWS participating in less MVPA during the weekends and less VPA during the weekends than OB controls. There was a trend towards PWS participating in less VPA on weekends compared to weekdays, while OB participated similarly in VPA on weekdays and weekend days. On average, neither PWS nor OB children met minimum MVPA recommendations. The results suggest there is a need to design exercise programs for PWS youth that focus on integrating vigorous intensity activities, especially during the weekends when structured PA may not be available.

    The ability of different obesity indices to predict cardiovascular risk is still debated in youth and few data are available in sub Saharan Africa. We compared the associations between several indices of obesity and cardiovascular risk factors (CVRFs) in late adolescence in the Seychelles. We measured body mass index (BMI), waist circumference, waist/hip ratio (WHiR), waist/height ratio (WHtR) and percent fat mass (by bioimpedance) and 6 CVRFs (blood pressure, LDL-cholesterol, HDL-cholesterol, triglycerides, fasting blood glucose and uric acid) in 423 youths aged 19-20 years from the general population. The prevalence of overweight/obesity and several CVRFs was high, with substantial sex differences. Except for glucose in males and LDL-cholesterol in females, all obesity indices were associated with CVRFs. BMI consistently predicted CVRFs at least as well as the other indices. Linear regression on BMI had standardized regression coefficients of 0.25-0.36 for most CVRFs (p<0.01) and ROC analysis had an AUC between 60%-75% for most CVRFs. BMI also predicted well various combinations of CVRFs: 36% of male and 16% of female lean subjects (BMI P90). There was an elevated prevalence of obesity and of several CVRFs in youths in Seychelles. BMI predicted single or combined CVRFs at least as well as other simple obesity indices.

    Worksites provide multiple advantages to prevent and treat obesity and to test environmental interventions to tackle its multiple causal factors. We present a literature review of group-randomized and non-randomized trials that tested worksite environmental, multiple component interventions for obesity prevention and control paying particular attention to the conduct of formative research prior to intervention development. The evidence on environmental interventions on measures of obesity appears to be strong since most of the studies have a low (4/8) and unclear (2/8) risk of bias. Among the studies reviewed whose potential risk of bias was low, the magnitude of the effect was modest and sometimes in the unexpected direction. None of the four studies describing an explicit formative research stage with clear integration of findings into the intervention was able to demonstrate an effect on the main outcome of interest. We present alternative explanation for the findings and recommendations for future research.

    With the growing prevalence of childhood obesity and type 2 diabetes mellitus (T2DM) in youth, the challenge of cardiovascular disease risk management has entered the paediatric realm, affecting specialists, family physicians and allied healthcare professionals alike. Currently, there is little evidence to support optimal strategies for management of T2DM in youth and the associated cardiovascular complications. Physical activity plays a powerful role in the prevention and management of T2DM and cardiovascular disease in adults. This review will focus on the role of physical activity for the prevention of T2DM in youth and its associated cardiovascular complications. The first part describes the prevalence of cardiovascular risk factors in this cohort. The second part focuses on the role of physical activity in the prevention and management of T2DM in youth. Collectively, the limited intervention and observation studies published to date suggest that daily targets of 60-90 minutes of physical activity and less than 60 minutes of screen time (i.e. time spent in front of a television, computer or video games) are required for the prevention and management of T2DM in youth. Large-scale intervention studies are needed to determine the most effective physical activity strategies for the prevention and management of T2DM in youth.

    The worrisome rise in pediatric type 2 diabetes (T2DM) is most prevalent among minority ethnic/racial populations. Typically, T2DM occurs during puberty in high risk obese adolescents with evidence of insulin resistance. Screening for T2DM in obese youth can be a daunting task for pediatricians and differentiating between pediatric T1DM and T2DM in obese youth can be challenging for pediatric endocrinologists. There is very limited data regarding the prevalence of T2DM among youth < 10 years of age. Here we present the case of a 5-year-old Hispanic male diagnosed with T2DM after referral by his pediatrician for abnormal weight gain, acanthosis nigricans and an elevated HbgA1c. He subsequently became symptomatic for diabetes with confirmed hyperglycemia and HbgA1c of 9.7% (83 mmol/mol) at the time of formal diagnosis. Type 1 diabetes autoantibodies (GAD65, Islet, and ZincT8) and monogenic diabetes genetic tests were negative. Due to elevated liver enzymes and baseline HbgA1c, he received basal insulin as his initial therapy. In this paper, we will discuss this case and present an IRB approved retrospective review of the characteristics of the 20 T2DM patients <10 years of age identified to date in our pediatric diabetes center. This review highlights that while uncommon, the diagnosis of T2DM merits consideration even in prepubertal children. This is especially true when working with a high risk population, such as our Hispanic South Texas youth. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Recent studies indicate that fractures in obese postmenopausal women and older men contribute significantly to the overall fracture burden. The effect of obesity is to some extent site-dependent, the risk being increased for some fractures and decreased for others, possibly related to different patterns of falling and the presence or absence of soft tissue padding. Risk factors for fracture in obese individuals appear to be similar to those in the nonobese population, although falls may be particularly important in the obese. There is some evidence that the morbidity associated with fractures in obese individuals is greater than in the nonobese; however, a recent study indicates that the mortality associated with fracture is lower in obese and overweight people than in those of normal weight. The evidence base for strategies to prevent fractures in obese individuals is weak and is an important area for future research.

    Both obesity and congenital heart disease (CHD) are risk factors for the long-term cardiovascular health of children and adolescents. The addition of smart mobile technology to conventional lifestyle counseling for weight management offers great potential to appeal to technologically literate youth and can address a large geographical area with minimal burden to participants. This pilot study seeks to examine the influence of a 1-year lifestyle intervention on nutrition and physical activity-related health outcomes in overweight or obese children and adolescents with CHD. This is a pilot and feasibility study which utilizes a single-arm, prospective design with a goal to recruit 40 overweight and obese patients. The feasibility metrics will evaluate the integrity of the study protocol, data collection and questionnaires, recruitment and consent, and acceptability of the intervention protocol and primary outcome measures. The primary clinical outcome metrics are anthropometry, body composition, and cardiorespiratory exercise capacity. The secondary clinical metrics include quality of life, nutrition and physical activity behavior, lung and muscle function, and cardio-metabolic risk factors. Outcomes are assessed at baseline, 6 months, and 1 year. To date, a total of 36 children and youth (11 girls), aged 7-17 years (mean = 14.4 years), have commenced the intervention. Recruitment for the study was initiated in June 2012 and is currently ongoing. The information provided in this paper is intended to help researchers and health professionals with the development and evaluation of similar lifestyle intervention programs. Since the application of smartphones to pediatric cardiac health and obesity management is a novel approach, and continued research in this area is warranted, this paper may serve as a foundation for further exploration of this health frontier and inform the development of a broader strategy for obesity management in pediatric cardiology.

    The promotion of family planning and birth control in Pacific countries is often frustrated by traditional and religious beliefs, if not deterred by tremendous funding and logistics problems. In the central Pacific republic of the Marshall Islands, however, youthful health workers are taking a unique approach to health promotion that has spurred acceptance of the once controversial subjects of family planning and birth control. A group known as Youth to Youth in Health is spearheading a family planning outreach drive in the schools and community in the Marshall Islands. Coupling health presentations with traditional island music and dance to produce lively health shows, the group's programs on family planning, birth control, nutrition, and cancer have struck a responsive chord in a culture known for its religious and traditional conservatism. The group makes creative use of puppet shows, skits, health songs, and pantomimes, interspersed with contemporary renditions of Marshall Islands music and traditional dances. These have rekindled pride in their culture among the group and sparked a sense of urgency about the need to improve health conditions in the islands. As evidence of the group's impact, family planning staff point to a nearly 4-fold rise in the number of youth clients under 19 years since the Youth to Youth started in mid-1986. Their combination of traditional custom with family planning and other health information has proved to be an innovative and needed program for the islands.

    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.

    Adolescence and young adulthood, a period essential for determining exposures over the life-course, is an ideal time to intervene to lower cancer risk. This demographic group can be viewed as both the target audience and generator of messages for cancer prevention, such as skin cancer, obesity-, tobacco-, and human papillomavirus-related cancers. The purpose of this paper is to encourage innovative health communications that target youth; youth behavior; and the structural, environmental, and social determinants of youth behavior as critical areas of focus for cancer prevention and disparities reduction. The authors describe the rationale, processes, products, and early impacts of an award-winning youth diabetes prevention communication campaign model (The Bigger Picture) that harnesses spoken-word messages in school-based and social media presentations. The campaign supports minority adolescent and young adult artists to create content that aligns with values held closely by youth-values likely to resonate and affect change, such as defiance against authority, inclusion, and social justice. This campaign can be leveraged to prevent obesity, which is a cancer risk factor. Then, the authors propose concrete ways that The Bigger Picture's pedagogical model could be adapted for broader cancer prevention messaging for youth of color and youth stakeholders regarding tobacco-related cancers, skin cancers, and human papillomavirus-related cancers. The goal is to demonstrate how a youth-generated and youth-targeted prevention campaign can: (1) reframe conversations about cancer prevention, (2) increase awareness that cancer prevention is about social justice and health equity, and (3) catalyze action to change social norms and confront the social and environmental drivers of cancer disparities.

    Among United States youth there is an obesity epidemic with potential life-long health implications. To date, relationships between the built environment and body mass index (BMI) have not been evaluated for youth, and have not been evaluated longitudinally. To determine if urban sprawl is associated with BMI for U.S. youth. Using data from the 1997 National Longitudinal Survey of Youth (NLSY97), both cross-sectional and longitudinal analyses were conducted. Hierarchical modeling was used to relate characteristics of individuals, households, and places to BMI. Individual and household data were extracted from the NLSY97. The independent variable of interest was the county sprawl index, which was derived with principal components analyses from census and other data. In a cross-sectional analysis, the likelihood of U.S. adolescents (aged 12-17 years) being overweight or at risk of overweight (> or =85th percentile relative to the Centers for Disease Control growth charts) was associated with county sprawl (p=0.022). In another cross-sectional analysis, after controlling for sociodemographic and behavioral covariates, the likelihood of young adults (aged 18-23 years) being obese was also associated with county sprawl (p=0.048). By contrast, in longitudinal analyses, BMI growth curves for individual youth over the 7 years of NLSY97, and BMI changes for individual youth who moved between counties, were not related to county sprawl (although coefficient signs were as expected). Cross-sectional analyses suggest that urban form is associated with being overweight among U.S. youth. The strength of these relationships proved comparable to those previously reported for adults. Longitudinal analyses show no such relationship. It is unclear why these approaches give different results, but sample sizes, latent effects, and confounders may contribute.

    First Nations people are experiencing increasing rates of obesity and type 2 diabetes but no anthropometric information exists from before the 1950s to provide context to these epidemics. To compare anthropometric indices of First Nations children and youth on first entering residential schools with historical and contemporary reference groups. This observational cross-sectional study used archival records from the Department of Indian Affairs to calculate body mass index (BMI), height for age (HA) and weight for age (WA) of all known children and youth undergoing physical examinations on first entering residential schools in Saskatchewan and Manitoba from 1919 to 1953. Proportions of children and youth in each BMI category were determined by age, sex, time period and residential school. Z-scores for HA and WA were determined by age group and sex. Finally, median heights and weights were compared with a non-Indigenous cohort from the 1953 Canadian survey. On admission to residential schools, 1,767 First Nations children and youth (847 boys, 920 girls) were more likely to have normal BMIs (79.8%) than Canadian children and youth today (66.5%), but lower rates of overweight/obesity (10.9% vs. 32.0%) and higher rates of underweight (9.3% vs. <2.0%). There was an overall trend of diminishing levels of underweight and increasing levels of overweight/obesity over time. Although 6.6% of boys and 7.9% of girls had HA Z-scores >-2, age-specific median heights tended to be higher than Canadian children and youth in 1953. Under 3% of children and youth had WA Z-scores of >-2. A large majority of First Nations children and youth exhibited normal anthropometric indices on first entering residential schools in Manitoba and Saskatchewan from 1919 to 1953. These historical findings provide an important context to the current epidemics of obesity and type 2 diabetes and suggest that the nutritional conditions in these First Nations children's communities were satisfactory during

  6. Is sleep deprivation a contributor to obesity in children?

    2016-03-01

    Chronic lack of sleep (called "sleep deprivation") is common in modern societies with 24/7 availability of commodities. Accumulating evidence supports the role of reduced sleep as contributing to the current obesity epidemic in children and youth. Longitudinal studies have consistently shown that short sleep duration is associated with weight gain and the development of obesity. Recent experimental studies have reported that sleep restriction leads to weight gain in humans. Increased food intake appears to be the main mechanism by which insufficient sleep results in weight gain. Voluntary sleep restriction has been shown to increase snacking, the number of meals eaten per day, and the preference for energy-dense foods. Although the causes of sleep loss in the pediatric population are numerous, more research looking at screen exposure before bedtime and its effects on sleep is needed given the pervasiveness of electronic media devices in today's environment. Health professionals should routinely ask questions about sleep and promote a good night's sleep because insufficient sleep impacts activity and eating behaviors. Future research should examine the clinical benefits of increasing sleep duration on eating behaviors and body weight control and determine the importance of adequate sleep to improve the treatment of obesity.

Associations between three adversity exposures before age 18 years (history of physical abuse, alcohol problems, or mental illness in the household) and two maternal weight outcomes (prepregnancy obesity and excessive gestational weight gain) were modeled separately using survey-adjusted log-binomial models. After adjusting for race/ethnicity and early-life socioeconomic factors, childhood physical abuse was associated with a 60% increase in the risk of prepregnancy obesity (adjusted risk ratio=1.6, 95% CI=1.1, 2.2). Household alcohol abuse was associated with a 30% increase in prepregnancy obesity (adjusted risk ratio=1.3, 95% CI=1.0, 1.7), as was household mental illness (adjusted risk ratio=1.3, 95% CI=0.8, 1.9), but the mental illness exposure was not significant. Physical abuse and household alcohol abuse were associated with a significant 20% increase in the risk of excessive gestational weight gain; mental illness was not. Adversity in early life may affect maternal weight before and during pregnancy. Screening and treating women of reproductive age for childhood adversity and its negative effects could significantly reduce obesity-related health outcomes for women and their children.

  8. Reaching the healthy people goals for reducing childhood obesity: closing the energy gap.

    The federal government has set measurable goals for reducing childhood obesity to 5% by 2010 (Healthy People 2010), and 10% lower than 2005-2008 levels by 2020 (Healthy People 2020). However, population-level estimates of the changes in daily energy balance needed to reach these goals are lacking. To estimate needed per capita reductions in youths' daily "energy gap" (calories consumed over calories expended) to achieve Healthy People goals by 2020. Analyses were conducted in 2010 to fit multivariate models using National Health and Nutrition Examination Surveys 1971-2008 (N=46,164) to extrapolate past trends in obesity prevalence, weight, and BMI among youth aged 2-19 years. Differences in average daily energy requirements between the extrapolated 2020 levels and Healthy People scenarios were estimated. During 1971-2008, mean BMI and weight among U.S. youth increased by 0.55 kg/m(2) and by 1.54 kg per decade, respectively. Extrapolating from these trends to 2020, the average weight among youth in 2020 would increase by ∼1.8 kg from 2007-2008 levels. Averting this increase will require an average reduction of 41 kcal/day in youth's daily energy gap. An additional reduction of 120 kcal/day and 23 kcal/day would be needed to reach Healthy People 2010 and Healthy People 2020 goals, respectively. Larger reductions are needed among adolescents and racial/ethnic minority youth. Aggressive efforts are needed to reverse the positive energy imbalance underlying the childhood obesity epidemic. The energy-gap metric provides a useful tool for goal setting, intervention planning, and charting progress. Copyright © 2012 American Journal of Preventive Medicine. Published by Elsevier Inc.

    To examine the current extent of the obesity problem in 2 large pediatric clinical registries in the US and Europe and to examine the hypotheses that increased body mass index (BMI) z-scores (BMIz) are associated with greater hemoglobin A1c (HbA1c) and increased frequency of severe hypoglycemia in youth with type 1 diabetes (T1D). International (World Health Organization) and national (Centers for Disease Control and Prevention/German Health Interview and Examination Survey for Children and Adolescents) BMI references were used to calculate BMIz in participants (age 2-<18 years and ≥ 1 year duration of T1D) enrolled in the T1D Exchange (n = 11,435) and the Diabetes Prospective Follow-up (n = 21,501). Associations between BMIz and HbA1c and severe hypoglycemia were assessed. Participants in both registries had median BMI values that were greater than international and their respective national reference values. BMIz was significantly greater in the T1D Exchange vs the Diabetes Prospective Follow-up (P < .001). After stratification by age-group, no differences in BMI between registries existed for children 2-5 years, but differences were confirmed for 6- to 9-, 10- to 13-, and 14- to 17-year age groups (all P < .001). Greater BMIz were significantly related to greater HbA1c levels and more frequent occurrence of severe hypoglycemia across the registries, although these associations may not be clinically relevant. Excessive weight is a common problem in children with T1D in Germany and Austria and, especially, in the US. Our data suggest that obesity contributes to the challenges in achieving optimal glycemic control in children and adolescents with T1D. Copyright © 2015 Elsevier Inc. All rights reserved.

    During childhood, excessive weight is negatively associated with the development of motor skills, with children with overweight or obesity having poorer motor skills compared to children with normal weight. The objectives of the current study are to identify the differences in motor skills between children and adolescent with obesity and severe obesity and the extent of this difference. To do so, we examined cross-sectionally 165 subjects. Physical fitness was analyzed in both participants with obesity (>97-99.9 BMI percentile) and severe obesity (>99.9 BMI percentile) using eight standardized tests: sit-and-reach, grip force, sit-ups, push-ups, balance, hand-eye coordination, standing long jump and 5-meter shuttle run. Poorer performance were observed in participants with severe obesity in sit-ups (children: 59%; 18.6±17.0 percentile value vs. 29.5±23.2 percentile value, p=0.008), balance (adolescent: 59%; 12.1±12.2 sec. v. 19.3±13.9 sec., p=0.034) and in the 5-meter shuttle run (children: 49%; 14.0±13.9 percentile value vs. 20.8 ± 19.4 percentile value, p=0.046; adolescents: 11%; 13.2±2.2 sec. vs. 11.8±1.6 sec., p=0.008) compared to obese counterparts. In conclusion, while physical performance was found to be similar between the different obesity levels for the majority of tests, youth with severe obesity demonstrated impairments ranging from 11 to 59% in specific tests.

    Little research has been performed to examine patient perceptions of weight-related language, especially related to childhood obesity. In this study we assessed parental perceptions of weight-based terminology used by health care providers to describe a child's excess weight and assessed perceived connotations associated with these terms including stigma, blame, and motivation to reduce weight. A national sample of American parents with children aged 2 to 18 years (N = 445) completed an online survey to assess their perceptions of 10 common terms to describe excess body weight in youth (including "extremely obese," "high BMI," "weight problem," "unhealthy weight," "weight," "heavy," "obese," "overweight," "chubby," and "fat"). Parents were asked to use a 5-point rating scale to indicate how much they perceived each term to be desirable, stigmatizing, blaming, or motivating to lose weight. Regression models revealed that the terms "weight" and "unhealthy weight" were rated as most desirable, and "unhealthy weight" and "weight problem" were rated as the most motivating to lose weight. The terms "fat," "obese," and "extremely obese" were rated as the most undesirable, stigmatizing, blaming, and least motivating. Parents' ratings were consistent across sociodemographic variables, body weight, and child's body weight. The results of this study have important implications for the improvement of health care for youth with obesity; it may be advantageous for health care providers to use or avoid using specific weight-based language during discussions about body weight with families. Pediatricians play a key role in obesity prevention and treatment, but their efforts may be undermined by stigmatizing or offensive language that can hinder important discussions about children's health.

  13. Gender-specific effects of early nutritional restriction on adult obesity risk: evidence from quasi-experimental studies.

    PubMed

    Robinson, Whitney R

    2012-12-01

    In countries undergoing nutrition transition and historically poor minority groups in wealthy countries, obesity tends to be more common in women than men. A potential contributor to this female excess of obesity is a mismatch between perinatal nutritional restriction and a later calorie-rich environment. Several epidemiologic and quasi-experimental studies support a gender-differential effect of early nutritional deprivation on adult obesity. The quasi-experimental studies are of particular interest because results of quasi-experimental studies are typically less vulnerable to confounding bias than observational studies. Four quasi-experimental studies-exploiting 20th century famines that occurred in Europe, Africa, and Asia-provide evidence that perinatal nutritional restriction followed by relative caloric abundance may increase adult obesity risk to a greater extent in women than men. If the findings are accurate and generalizable to contemporary food environments, they suggest that the female offspring of poor, or otherwise nutritionally restricted, women in rapidly developing and wealthy countries may be at particularly high risk of adult obesity. Research into gender-specific effects of early life nutritional deprivation and its interactions with later environmental exposures may provide insight into global gender differences in obesity prevalence.

  14. Decomposing socioeconomic inequalities in childhood obesity: evidence from Ireland.

    The objective of this paper is to quantify and decompose the socioeconomic gradient in childhood obesity in the Republic of Ireland. The analysis is performed using data from the first wave of the Growing Up in Ireland survey, a nationally representative survey of 8568 nine-year-old children conducted in 2007 and 2008. We estimate concentration indices to quantify the extent of the socioeconomic gradient in childhood obesity and undertake a subsequent decomposition analysis to pinpoint the key factors underpinning the observed inequalities. Overall the results confirm a strong socioeconomic gradient in childhood obesity in the Republic of Ireland. Concentration indices of obesity (CI=-0.168) and overweight/obese (CI=-0.057) show that the gradient is more pronounced in obese children, while results from the decomposition analysis suggest that the majority of the inequality in childhood obesity is explained by parental level variables. Our findings suggest that addressing childhood obesity inequalities requires coordinated policy responses at both the child and parental level. Copyright © 2014 Elsevier B.V. All rights reserved.

    There is evidence that hypertension is frequently associated with overweight/obesity even in kids and adolescents. Either conditions influence development of left ventricular (LV) hypertrophy (LVH), through different biological and hemodynamic mechanisms: obesity is conventionally thought to elicit a coherent growth of LV chamber dimensions and myocardial wall thickness (eccentric LV geometry), whereas a more accentuated increase in wall-thickness (concentric LV geometry) is attributed to hypertension. While during youth these differences are visible, proportion of LV concentric geometry, the most harmful LV geometric pattern, sharply raises in obese individuals during middle age, and becomes the most frequent geometric patterns among obese-hypertensive individuals. Two conditions with elevated hemodynamic impact, severe obstructive sleep apnea and masked hypertension contribute to the development of such a geometric pattern, but non-hemodynamic factors, and specifically body composition, also influence prevalence of concentric LV geometry. Contrasting a general belief, it has been observed that adipose mass strongly influences LV mass, particularly in women, especially when fat-free mass is relatively deficient. Thus, though blood pressure control is mandatory for prevention and reduction of LVH in obese hypertensive patients, without reduction of visceral adiposity regression of LVH is difficult. Future researches should be addressed on (1) assessing whether LVH resulting from alteration of body composition carries the same prognosis as pressure overload LVH; (2) defining tissue characterization of the hypertrophic heart in obese-hypertensive patients; (3) evaluating whether assessment of hemodynamic loading conditions and biological markers can help defining management of the association of obesity with hypertension.

    Background: Childhood obesity has been becoming a worldwide public health problem. We conducted a community-based physical activity (PA) intervention program aiming at childhood obesity prevention in general student population in Nanjing of China, the host city of the 2nd World Summer Youth Olympic Games (YOG-Obesity study). Methods: This was a cluster randomized controlled intervention study. Participants were the 4th (mean age±s.e.: 9.0±0.01) and 7th (mean age±s.e.: 12.0±0.01) grade students (mean age±s.e.: 10.5±0.02) from 48 schools and randomly allocated (1:1) to intervention or control groups at school level. Routine health education was provided to all schools, whereas the intervention schools additionally received an 1-year tailored multi-component PA intervention program, including classroom curricula, school environment support, family involvement and fun programs/events. The primary outcome measures were changes in body mass index, obesity occurrence and PA. Results: Overall, 9858 (97.7%) of the 10091 enrolled students completed the follow-up survey. Compared with the baseline, PA level increased by 33.13 min per week (s.e. 10.86) in the intervention group but decreased by 1.76 min per week (s.e. 11.53) in the control group (P=0.028). After adjustment for potential confounders, compared with the control group, the intervention group were more likely to have increased time of PA (adj. Odds ratio=1.15, 95% confidence interval=1.06–1.25), but had a smaller increase in mean body mass index (BMI) (0.22 (s.e. 0.02) vs 0.46 (0.02), P=0.01) and BMI z-score (0.07 (0.01) vs 0.16 (0.01), P=0.01), and were less likely to be obese (adj. Odds ratio=0.7, 95% confidence interval=0.6, 0.9) at study end. The intervention group had fewer new events of obesity/overweight but a larger proportion of formerly overweight/obese students having normal weight by study end. Conclusions: This large community-based PA intervention was feasible and effective in promoting PA

    To describe efforts to implement evidence-based interventions (EBIs) within multicomponent, community-wide initiatives to reduce teen pregnancy. During 2011-2014, we collected information about the capacity (i.e., knowledge, confidence, training, and experience) of state and community-based organizations to support implementation of the following: EBIs, number and characteristics of youth served by EBIs, type of EBIs implemented, EBI settings, hours of training, and technical assistance provided. State and community-based organizations reported these data annually; however, training and technical assistance was reported monthly. We used aggregated data from these annual and monthly reports to describe the implementation of EBIs in the community-wide initiative project. From baseline in 2011-2014, state and community-based organizations increased their capacities to support program partners in delivering EBIs. They provided 5,015 hours of technical assistance and training on topics, including ensuring adequate capacity, process and outcome evaluation, program planning, and continuous quality improvement. Program partners increased the number of youth reached by an EBI in targeted communities by 349%, from 4,304 in the first year of implementation in 2012 to 19,344 in 2014. Most youth in 2014 received sexuality education programs (59%), whereas smaller percentages received abstinence-based, youth development, and clinic-based programs. Most youth were reached through schools (72%) and community-based organizations (16%), and smaller numbers were reached in other settings (e.g., faith-based organizations, health centers). Building and monitoring the capacity of program partners to deliver EBIs through technical assistance and training is important. In addition, partnering with schools leads to reaching more youth.

    We examined the relationship between fast-food restaurants near schools and obesity among middle and high school students in California. We used geocoded data (obtained from the 2002-2005 California Healthy Kids Survey) on over 500,000 youths and multivariate regression models to estimate associations between adolescent obesity and proximity of fast-food restaurants to schools. We found that students with fast-food restaurants near (within one half mile of) their schools (1) consumed fewer servings of fruits and vegetables, (2) consumed more servings of soda, and (3) were more likely to be overweight (odds ratio [OR] = 1.06; 95% confidence interval [CI] = 1.02, 1.10) or obese (OR = 1.07; 95% CI = 1.02, 1.12) than were youths whose schools were not near fast-food restaurants, after we controlled for student- and school-level characteristics. The result was unique to eating at fast-food restaurants (compared with other nearby establishments) and was not observed for another risky behavior (smoking). Exposure to poor-quality food environments has important effects on adolescent eating patterns and overweight. Policy interventions limiting the proximity of fast-food restaurants to schools could help reduce adolescent obesity.

    With the rise of type 2 diabetes in youth, it is critical to investigate factors such as physical activity (PA) and time spent sedentary that may be contributing to this public health problem. This article describes PA and sedentary time in a large cohort of youth with type 2 diabetes and compares these levels with other large-scale investigations. The Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) trial is a study in 699 youth, recruited from 15 US clinical centers, aged 10 to 17 years with <2 years of type 2 diabetes and a BMI ≥85th percentile. In comparison with the subset of the NHANES cohort who were obese (BMI ≥95th percentile), TODAY youth spent significantly more time being sedentary (difference averaging 56 minutes per day; P < .001) as assessed by accelerometry. Although moderate to vigorous activity levels in both obese cohorts for all age groups were exceptionally low, younger TODAY boys were still significantly less active than similarly aged NHANES youth. Comparisons between the TODAY girls and other investigations suggest that the TODAY girls also had relatively lower PA and fitness levels. Adolescents with type 2 diabetes from the large TODAY cohort appear to be less physically active and tend to spend more time being sedentary than similarly aged youth without diabetes identified from other large national investigations. Treatment efforts in adolescents with type 2 diabetes should include decreasing sitting along with efforts to increase PA levels.

    An uncontrolled study was conducted to evaluate the effects of a group-based program on weight control, metabolic profiles, and obesity-related complications in obese youth. The program consisted of an initial in-patient session and five group sessions, one, two, three, six, and nine months into the study, providing participants and their parents with information about the consequences of obesity and lifestyle modifications. The severity of obesity and obesity-related complications were evaluated at baseline and 12 months after the intervention. The participants' and their parents' perceptions of the program were assessed. Of the obese youth recruited (n=126), 115 completed the study. Their percentage weight for height and percentage body fat decreased significantly (both p<0.001), and their insulin resistance, lipid profiles, and transaminases levels improved (all p<0.01). The prevalence of prediabetes, dyslipidemia, and elevated transaminases decreased significantly (all p<0.05). The participants and their parents perceived the program as valuable. A group-based program is effective in managing childhood obesity, improving metabolic profiles, and alleviating certain obesity-related complications. A group-based program that provides education and raises the awareness of obese children and their parents about the consequences of obesity is an effective model for treating childhood obesity.

    2013-06-01

    A growing body of research has examined callous-unemotional (CU) traits among samples of antisocial youth. Debate surrounds the malleability of CU traits and their responsiveness to parenting and parent-focused interventions. This review examines evidence from studies that have investigated various relationships between parenting, CU traits, and antisocial behavior (AB). Studies were categorized according to five distinct research questions each addressing associations among parenting, CU traits, and AB in a different way. The results suggest that dimensions of parenting are prospectively related to changes in CU traits. Subgroups of youth with both high levels of CU traits and AB also appear to have experienced negative parenting practices. However, negative parenting is not consistently related to AB in cross-sectional studies for youth with high levels of CU traits. At the same time, parenting-focused interventions appear effective in reducing the level of AB and CU traits in youth. The findings and implications for future studies are critically discussed as they pose challenges for current etiological theories of AB. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Objective To assess the effects of a 12-week gardening, nutrition, and cooking intervention (“LA Sprouts”) on dietary intake, obesity parameters and metabolic disease risk among low-income, primarily Hispanic/Latino youth in Los Angeles. Methods Randomized control trial involving four elementary schools [2 schools randomized to intervention (172, 3rd–5th grade students); 2 schools randomized to control (147, 3rd–5th grade students)]. Classes were taught in 90-minute sessions once a week to each grade level for 12 weeks. Data collected at pre- and post-intervention included dietary intake via food frequency questionnaire (FFQ), anthropometric measures [BMI, waist circumference (WC)], body fat, and fasting blood samples. Results LA Sprouts participants had significantly greater reductions in BMI z-scores (0.1 versus 0.04 point decrease, respectively; p=0.01) and WC (−1.2 cm vs. no change; p<0.001). Fewer LA Sprouts participants had the metabolic syndrome (MetSyn) after the intervention than before, while the number of controls with MetSyn increased. LA Sprouts participants had improvements in dietary fiber intake (+3.5% vs. −15.5%; p=0.04) and less decreases in vegetable intake (−3.6% vs. −26.4%; p=0.04). Change in fruit intake before and after the intervention did not significantly differ between LAS and control subjects. Conclusions LA Sprouts was effective in reducing obesity and metabolic risk.

    This systematic review evaluates the relationship between resistance training and metabolic function in youth. PubMed, Embase, Cochrane Library, Web of Science, CINAHL, and ClinicalTrials. gov were searched for articles that (1): studied children (2); included resistance training (3); were randomized interventions; and (4) reported markers of metabolic function. The selected studies were analyzed using the Cochrane Risk-of-Bias Tool. Thirteen articles met inclusion criteria. Mean age ranged from 12.2 to 16.9 years, but most were limited to high school (n = 11) and overweight/obese (n = 12). Sample sizes (n = 22-304), session duration (40-60min), and intervention length (8-52 wks) varied. Exercise frequency was typically 2-3 d/wk. Resistance training was metabolically beneficial compared with control or resistance plus aerobic training in 5 studies overall and 3 out of the 4 studies with the fewest threats to bias (p ≤ .05); each was accompanied by beneficial changes in body composition, but only one study adjusted for change in body composition. Limited evidence suggests that resistance training may positively affect metabolic parameters in youth. Well-controlled resistance training interventions of varying doses are needed to definitively determine whether resistance training can mitigate metabolic dysfunction in youth and whether training benefits on metabolic parameters are independent of body composition changes.

  5. Intended and unintended effects of restrictions on the sale of cigarillos to youth: evidence from Canada.

    Youth consumption of cigarillos (ie, little cigars) has increased markedly in recent years. In July 2010, the Canadian government banned the sale of flavoured cigarillos and required unflavoured cigarillos to be sold in packs of at least 20 units. This paper assesses changes in young persons' use of cigarillos and regular cigars, which are potential substitutes, following the policy. To investigate of the change in cigar smoking following the policy, we constructed a segmented regression model that allowed the policy to change the height and the slope of the trend in the outcome variables. The model was estimated using data from the 2007-2011 Canadian Tobacco Use Monitoring Surveys. We obtained visual and regression-based evidence that use of cigarillos among youth declined following the policy. We also found a small, gradual increase in their use of regular cigars, possibly due to their compensatory switching from cigarillos to regular cigars. Overall, there was a net reduction in cigar use among youth after the intervention. The policy achieved its goal of reducing youth's consumption of cigarillos, but may have an unintended consequence of increasing their use of regular cigars. Policymakers should address the possibility that youth switch to regular cigars in response to restricted access to cigarillos. Possible ways of discouraging this substituting behaviour include extending the ban to cover all flavoured cigars and mandating a minimum pack size for all cigars, or raising taxes on flavoured cigars.

    The increased prevalence of obesity in children and its complications have led to a greater interest in studying baroreflex sensitivity (BRS) in children. This review of BRS in children and adolescents includes subtopics on: 1. Resting values of BRS and their reproducibility, 2. Genetics of BRS, 3. The role of a primarily low BRS and obesity in the development of hypertension, and 4. Association of diabetes mellitus, BRS, and obesity. The conclusions specific to this age follow from this review: 1. The mean heart rate (HR) influences the measurement of BRS. Since the mean HR decreases during adolescence, HR should be taken into account. 2. A genetic dependency of BRS was found. 3. Low BRS values may precede pathological blood-pressure elevation in children with white-coat hypertension. We hypothesize that low BRS plays an active role in the emergence of hypertension in youth. A contribution of obesity to the development of hypertension was also found. We hypothesize that both factors, a primarily low BRS and obesity, are partially independent risk factors for hypertension in youths. 4. In diabetics, a low BRS compared to healthy children can be associated with insulin resistance. A reversibility of the BRS values could be possible after weight loss.

    The last two decades have witnessed dramatic increases in obesity and family instability. To the extent that the social stigma of obesity is a risk factor and family instability represents the potential compromise of important protective factors, their convergence may disrupt socioemotional health, especially during periods of heightened social uncertainty. Drawing on data from the National Longitudinal Study of Adolescent Health, this study found that obese youth at the start of high school had higher levels of internalizing symptoms and lower levels of perceived social integration in school only when they had also experienced multiple family transitions since birth. This pattern, however, did not hold for boys, and it did not extend to overweight (as opposed to obese) adolescents of either gender. PMID:22640529

    Cyberbullying is a new risk factor for the well-being of pediatric populations. Consequences of cyberbullying include both physical and mental health concerns such as depression, anxiety, and somatic concerns. Adolescents who have been victims of cyberbullying and developed secondary symptoms are often recommended to visit a healthcare provider to obtain effective, evidence-based treatment. To date, no interventions exist in the healthcare setting for adolescents who are victims of cyberbullying. The purpose of this project is to review interventional studies on cyberbullying that have components for adolescents who have been involved with cyberbullying and their parents and to provide recommendations on effective intervention components with the goal of guiding clinical practice. A systematic review was conducted using the Institute of Medicine guidelines. A comprehensive electronic literature search was completed targeting interventions of cyberbullying in any setting. No date limits were used. Literature was searched in MEDLINE, Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, Communication and Mass Media Complete, Education Information Resource Center (ERIC), and PsycINFO databases. The following search terms were applied "cyberbullying" + "intervention" or "treatment" or "therapy" or "program." Only articles with a pediatric population were selected for review. Seventeen cyberbullying intervention programs in 23 articles were found to meet the search criteria. The most frequently used intervention components included education on cyberbullying for the adolescent, coping skills, empathy training, communication and social skills, and digital citizenship. Parent education on cyberbullying was also found to be important and was included in programs with significant outcomes. As youth present to healthcare providers with symptoms related to cyberbullying, effective interventions are needed to guide evidence-based practice. This review

    This article describes a pilot youth advocacy initiative for obesity prevention informed by social cognitive theory, social network theory, and theories of community mobilization. With assistance from school and health leaders, adolescent-aged youth led a cafeteria food labeling and social marketing campaign. We implemented an anonymous survey 2 weeks prior to and again at the conclusion of the campaign, and used cafeteria records to track servings of fruits and vegetables. The campaign resulted in a significant increase in youths' confidence to identify healthy foods (OR 1.97, 95 % CI 1.01, 3.84, p = .048), and a significant increase in per person per day servings of fruits (0.02, p = .03) and vegetables (0.01, p = .02). The results of our pilot were promising, and the integration of concepts from multiple theories benefited the implementation process. Obesity prevention initiatives should include strategies that encourage youth to create health promotion community networks and lead changes to their social and physical environments.

    Introduction Overweight and obesity remain significant public health risks for youth in the United States, particularly among racial/ethnic minority groups. Efforts at obesity prevention and control have targeted youth and family members in diverse settings. Although involving parents in obesity prevention programs for youth may improve the potential of these programs, less is known about parents’ preferred methods of engagement, especially among racial/ethnic minority parents and parents whose primary language is not English. In this qualitative study, parents of middle-school–aged children were asked how best to engage their children in obesity prevention and control efforts. Methods We recruited 38 parents whose children attended Los Angeles middle schools to participate in focus groups. Two English-language focus groups with 14 parents of different racial/ethnic backgrounds and 2 Spanish language groups with 24 Latino parents were conducted from 2010 through 2011. We analyzed focus group transcripts by using content analysis using inductive and deductive techniques. Results Findings from focus groups confirmed that parents want to help their children avoid obesity but feel constrained in their ability to take action. Participants identified an overarching desire to become better parents as a potential incentive to engage in obesity prevention efforts. Parents advocated for family-focused approaches in obesity prevention programs, including family sports leagues and cooking classes. Most findings were consistent between language groups, but parents in the Spanish language groups cited language-related barriers. Conclusion The development and testing of simple programs that are sustainable, community-based, and family-focused may empower families to address obesity prevention and control. PMID:24698532

    Objective The purpose of this study was to examine the association of knee injuries with subsequent changes in body mass index and body composition during maturation in young females. Methods A prospective longitudinal study design was employed to evaluate young females active in soccer or basketball (N=862). Participants who completed at least 1-year follow-up to provide consecutive annual measures of BMIZ and %fat were included in the study analysis to determine the effect of knee injuries on the trajectory of these obesity markers in youth. Results Of the 71 reported knee injuries, 12 (17%) occurred in athletes at the prepubertal stage, 24 (34%) in athletes at the pubertal stage, and 35 (49%) in postpubertal athletes. Controlling for the effects of maturation, female athletes who reported knee injury demonstrated a greater yearly increase in BMIZ (LS means and 95% CI for the injured group=0.039 (−0.012 to 0.089), for the non-injured group=−0.019 (−0.066 to 0.029), and group difference=0.057 (0.005 to 0.11), p=0.03) and in %body fat (LS means and 95% CI for the injured group=1.05 (0.45 to 1.65), for the non-injured group=0.22 (−0.21 to 0.064), and group difference=0.83 (0.21 to 1.45), p=0.009), compared to those without knee injuries. This indicates that the athletes with knee injuries will increase their body mass index percentile by up to 5 units more than someone of the same age without an injury, and in body fat by up to 1.5%, compared to their non-injured peers. Conclusions The present findings indicate that knee injury during the growing years may be associated with unfavourable changes in body composition. PMID:23673521

    Childhood obesity rates have risen dramatically over the past few decades. Although obesity has been linked to poorer neurocognitive functioning in adults, much less is known about this relationship in children and adolescents. Therefore, we conducted a systematic review to examine the relationship between obesity and obesity-related behaviors with neurocognitive functioning in youth. We reviewed articles from 1976 to 2013 using PsycInfo, PubMed, Medline and Google Scholar. Search terms included cognitive function, neurocognitive function/performance, executive function, impulsivity, self-regulation, effortful control, cognitive control, inhibition, delayed gratification, memory, attention, language, motor, visuo-spatial, academic achievement, obesity, overweight, body mass index, waist-hip ratio, adiposity and body fat. Articles were excluded if participants had health problems known to affect cognitive functioning, the study used imaging as the only outcome measure, they were non-peer-reviewed dissertations, theses, review papers, commentaries, or they were non-English articles. Sixty-seven studies met inclusion criteria for this review. Overall, we found data that support a negative relationship between obesity and various aspects of neurocognitive functioning, such as executive functioning, attention, visuo-spatial performance, and motor skill. The existing literature is mixed on the effects among obesity, general cognitive functioning, language, learning, memory, and academic achievement. Executive dysfunction is associated with obesity-related behaviors, such as increased intake, disinhibited eating, and less physical activity. Physical activity is positively linked with motor skill. More longitudinal research is needed to determine the directionality of such relationships, to point towards crucial intervention time periods in the development of children, and to inform effective treatment programs.

    Abstract Background Addressing socio-economic inequalities in obesity is a public health priority and the workplace is seen as a potential health promotion site. However, there is a lack of evidence on what works. This article systematically reviews studies of the effects of workplace interventions on socio-economic inequalities in obesity. Methods Following PRISMA guidelines, we searched for published or unpublished experimental and observational evaluation studies. Nine electronic databases were searched as well as websites and bibliographies. Included studies were data extracted, quality assessed and narratively synthesized. Results Eighteen studies were included of which 14 examined behavioural interventions and 4 mixed or environmental ones. While most studies (n = 12) found no effects on inequalities in obesity—and a minority found increases (n = 3), there was also some evidence of potentially effective workplace interventions (n = 3) especially in terms of physical activity interventions targeted at lower occupational groups. Conclusion There is experimental evidence that workplace delivered physical activity interventions have the potential to reduce inequalities in obesity by targeting lower occupational groups. However, overall, the evidence base is small, largely from the USA, and of a low quality. More high-quality, experimental study designs are required. PMID:25316262

    The aim of this article is to show selected psychological mechanisms involved in the onset and maintenance of obesity in children and youth. This work presents a review of the literature related to the psychological determinants of obesity from different theoretical approaches. The role of the mother-child relationship, as well as the specific characteristics of the relationships within the family, have been emphasized in the onset of the disorder. Another topic discussed were the specifics of the body experience and certain body image distortions that promote the maintenance of the obese state. The control deficit caused by family relationships was also described.

    In Pakistan, the disease pattern is facing a huge changeover from acute and communicable diseases to the non-communicable diseases. Moreover, an emerging epidemic of obesity is still under recognized in Pakistan. A detailed review and dissemination of the existing knowledge to determine the extent of burden of obesity can help understand this important public health issue. A detailed literature review was conducted through PubMed search engines, regarding obesity burden in Pakistan. The original peer reviewed research articles, reports of WHO in English language, non-government organizations reports were included in the review. "Obesity AND Pakistan" were used as a search terms. Pakistan is suffering from epidemic of obesity, affecting all age groups. Urban population, particularly women shows considerable higher burden of obesity as compared to men and women from rural population. However, among children and adolescents there is variation in prevalence of obesity. Girls from all age groups are predominantly more obese as compared to boys. Most of the studies have estimated child obesity among school going children of different age groups and need careful interpretation. Pakistan is currently suffering from an emerging epidemic of obesity. The rising burden of obesity is widespread among adults (man and women) and children. The burden of obesity is higher among females in all age groups as compare to males. Effective interventions are required at population level to prevent and control this emerging public health issue.

  1. Effects of exercise training on chronic inflammation in obesity : current evidence and potential mechanisms.

    2013-04-01

    Chronic, systemic inflammation is an independent risk factor for several major clinical diseases. In obesity, circulating levels of inflammatory markers are elevated, possibly due to increased production of pro-inflammatory cytokines from several tissues/cells, including macrophages within adipose tissue, vascular endothelial cells and peripheral blood mononuclear cells. Recent evidence supports that adipose tissue hypoxia may be an important mechanism through which enlarged adipose tissue elicits local tissue inflammation and further contributes to systemic inflammation. Current evidence supports that exercise training, such as aerobic and resistance exercise, reduces chronic inflammation, especially in obese individuals with high levels of inflammatory biomarkers undergoing a longer-term intervention. Several studies have reported that this effect is independent of the exercise-induced weight loss. There are several mechanisms through which exercise training reduces chronic inflammation, including its effect on muscle tissue to generate muscle-derived, anti-inflammatory 'myokine', its effect on adipose tissue to improve hypoxia and reduce local adipose tissue inflammation, its effect on endothelial cells to reduce leukocyte adhesion and cytokine production systemically, and its effect on the immune system to lower the number of pro-inflammatory cells and reduce pro-inflammatory cytokine production per cell. Of these potential mechanisms, the effect of exercise training on adipose tissue oxygenation is worth further investigation, as it is very likely that exercise training stimulates adipose tissue angiogenesis and increases blood flow, thereby reducing hypoxia and the associated chronic inflammation in adipose tissue of obese individuals.

    Cigarette smoking is the leading cause of premature morbidity and mortality in the United States. The majority of children smoke their first cigarette in early adolescence, and many older teens have well-established dependence on nicotine. Efforts to promote and support smoking cessation among these youth smokers are critical. The available experimental studies of youth cessation interventions find that behavioral interventions increase the chances of youth smokers achieving successful cessation. Currently there is insufficient evidence for the effectiveness of pharmacological treatments with youth smokers. Many innovative studies have been compromised by challenges in recruiting sufficient numbers of youth, obtaining approval for waivers of parental consent, and high attrition in longitudinal studies. Key areas for future work include bridging the fields of adolescent development and treatment design, matching treatments to developmental trajectories of smoking behavior, better understanding treatment processes and treatment moderators, and building demand for evidence-based cessation treatments.

    Research investigating the body weight perceptions and eating-related weight control behaviors of First Nations (FN) youth living on reserve in Canada has been scarce. Knowledge of body weight perceptions may help to improve the relevance of initiatives promoting healthy weights. The purpose of this study was to examine the body weight perceptions and eating-related weight control behaviors of grade 6-8 on-reserve FN youth from seven Ontario communities. Data were collected from December 2003 to June 2010 from a convenience sample of FN youth (aged 10-14 years) using the Waterloo Web-based Eating Behaviour Questionnaire (WEB-Q). Participants were categorized into body mass index (BMI) categories based on International Obesity Task Force (IOTF) cut points. Frequency statistics were computed in the comparison of measured BMI and weight perceptions and weight control behaviors. Differences by BMI category were tested using Pearson Χ2 tests. A total of 267 youth from seven Ontario FN communities participated in the study (48.6% male). Overall, 36.3% of youth were overweight and 21.3% were obese (combined total of 57.6%). Similar to non-Aboriginal youth, a greater proportion of FN girls who were at a normal weight were concerned that their weight was too high compared to boys. However, one-third of normal weight boys were currently trying to lose weight. A greater proportion of obese girls were trying to lose weight compared to boys. Overall, a large proportion of both overweight boys and girls were attempting to gain weight. The present study provides a unique investigation into the weight perceptions and weight control behaviors of on-reserve FN youth living in isolated communities in Ontario, Canada. Many of the perceptions elucidated in this study are similar to those observed in non-Aboriginal youth, while others differed. The knowledge of these perceptions and further research to investigate what factors influences them will help to customize health promoting

    Reducing automobile dependence and improving rates of active transport may reduce the impact of obesogenic environments, thereby decreasing population prevalence of obesity and other diseases where physical inactivity is a risk factor. Increasing the relative cost of driving by an increase in fuel taxation may therefore be a promising public health intervention for obesity prevention. A scoping review of the evidence for obesity or physical activity effect of changes in fuel price or taxation was undertaken. Potential health benefits of an increase in fuel excise taxation in Australia were quantified using Markov modelling to simulate obesity, injury and physical activity related health impacts of a fuel excise taxation intervention for the 2010 Australian population. Health adjusted life years (HALYs) gained and healthcare cost savings from diseases averted were estimated. Incremental cost-effectiveness ratios (ICERs) were reported and results were tested through sensitivity analysis. Limited evidence on the effect of policies such as fuel taxation on health-related behaviours currently exists. Only three studies were identified reporting associations between fuel price or taxation and obesity, whilst nine studies reported associations specifically with physical activity, walking or cycling. Estimates of the cross price elasticity of demand for public transport with respect to fuel price vary, with limited consensus within the literature on a probable range for the Australian context. Cost-effectiveness modelling of a AUD0.10 per litre increase in fuel excise taxation using a conservative estimate of cross price elasticity for public transport suggests that the intervention would be cost-effective from a limited societal perspective (237 HALYs gained, AUD2.6 M in healthcare cost savings), measured against a comparator of no additional increase in fuel excise. Under "best case" assumptions, the intervention would be more cost-effective (3181 HALYs gained, AUD34.2

    Given the alarming prevalence of obesity worldwide and the need for interventions to halt the growing epidemic, more evidence on the role and impact of transport interventions for obesity prevention is required. This study conducts a scoping review of the current evidence of association between modes of transport (motor vehicle, walking, cycling and public transport) and obesity-related outcomes. Eleven reviews and thirty-three primary studies exploring associations between transport behaviours and obesity were identified. Cohort simulation Markov modelling was used to estimate the effects of body mass index (BMI) change on health outcomes and health care costs of diseases causally related to obesity in the Melbourne, Australia population. Results suggest that evidence for an obesity effect of transport behaviours is inconclusive (29% of published studies reported expected associations, 33% mixed associations), and any potential BMI effect is likely to be relatively small. Hypothetical scenario analyses suggest that active transport interventions may contribute small but significant obesity-related health benefits across populations (approximately 65 health adjusted life years gained per year). Therefore active transport interventions that are low cost and targeted to those most amenable to modal switch are the most likely to be effective and cost-effective from an obesity prevention perspective. The uncertain but potentially significant opportunity for health benefits warrants the collection of more and better quality evidence to fully understand the potential relationships between transport behaviours and obesity. Such evidence would contribute to the obesity prevention dialogue and inform policy across the transportation, health and environmental sectors. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aortic pulse wave velocity (PWV) measured via cardiac magnetic resonance (CMR) can be used to non-invasively assess changes in arterial stiffness and potential underlying vascular dysfunction. This technique could unmask early arterial dysfunction in overweight and obese youth at risk for cardiovascular disease. We sought to determine the association between vascular stiffness, percentage body fat, body mass index (BMI), and cardiac function in adolescents across the weight spectrum through both CMR and standard applanation tonometry (AT)-based PWV measurements. PWV and left-ventricular cardiac function were assessed using 3.0 T CMR in obese and overweight (OB/OW) participants (n = 12) and controls (n = 7). PWV was also estimated via carotid-femoral AT. OB/OW participants did not differ from healthy-weight controls regarding cardiometabolic risk factors or physical activity levels, but there was a trend towards higher levels of triglycerides in obese/overweight participants (P = 0.07). Mean PWV was higher in obese participants when corrected for age and sex (P = 0.01), and was positively associated with BMI (β = 0.51, P = 0.02). PWV estimated through AT was not significantly different between groups. Cardiac function measured by left-ventricular ejection fraction z-score was inversely associated with mean PWV (β = -0.57, P = 0.026). Increasing arterial stiffness and decreasing cardiac function were evident among our overweight and obese cohort. PWV estimated by CMR could detect early increases in arterial stiffness vs. traditional AT measurements of PWV. © 2017 World Obesity Federation.

    Women's experience of childhood adversity may contribute to their children's risk of obesity. Possible causal pathways include higher maternal weight and gestational weight gain, which have been associated with both maternal childhood adversity and obesity in offspring. This study included 6718 mother-child pairs from the National Longitudinal Survey of Youth 1979 in the United States (1979-2012). We applied multiple log-binomial regression models to estimate associations between three markers of childhood adversity (physical abuse, household alcoholism, and household mental illness) and offspring obesity in childhood. We estimated natural direct effects to evaluate mediation by prepregnancy BMI and gestational weight gain. Among every 100 mothers who reported physical abuse in childhood, there were 3.7 (95% confidence interval: -0.1 to 7.5) excess cases of obesity in 2- to 5-year olds compared with mothers who did not report physical abuse. Differences in prepregnancy BMI, but not gestational weight gain, accounted for 25.7% of these excess cases. There was no evidence of a similar relationship for household alcoholism or mental illness or for obesity in older children. In this national, prospective cohort study, prepregnancy BMI partially explained an association between maternal physical abuse in childhood and obesity in preschool-age children. These findings underscore the importance of life-course exposures in the etiology of child obesity and the potential multi-generational consequences of child abuse. Research is needed to determine whether screening for childhood abuse and treatment of its sequelae could strengthen efforts to prevent obesity in mothers and their children.

    The study evaluated the profile of circulating fatty acids (FA) in obese youth with and without metabolic syndrome (MetS) to determine its association with nutritional status, lifestyle and metabolic variables. A cross-sectional study was conducted in 96 young people, divided into three groups: obese with MetS (OBMS), obese (OB) and appropriate weight (AW). FA profiles were quantified by gas chromatography; waist circumference (WC), fat folds, lipid profile, high-sensitivity C-reactive protein, glucose, insulin, the homeostasis model assessment (HOMA index), food intake and physical activity (PA) were assessed. The OBMS group had significantly greater total free fatty acids (FFAs), palmitic-16:0 in triglyceride (TG), palmitoleic-16:1n-7 in TG and phospholipid (PL); in the OB group, these FAs were higher than in the AW group. Dihomo-gamma-linolenic (DHGL-20:3n-6) was higher in the OBMS than the AW in PL and FFAs. Linoleic-18:2n-6 in TG and PL had the lowest proportion in the OBMS group. WC, PA, total FFA, linoleic-18:2n-6 in TG and DHGL-20:3n-6 in FFAs explained 62% of the HOMA value. The OB group presented some higher proportions of FA and biochemical values than the AW group. The OBMS had proportions of some FA in the TG, PL and FFA fractions that correlated with disturbances of MetS.

    More educated adults have lower average body mass index (BMI). This may be due to selection, if adolescents with lower BMI attain higher levels of education, or it may be due to causation, if higher educational attainment reduces BMI gain in adulthood. We test for selection and causation in the National Longitudinal Survey of Youth 1979, which has followed a representative US cohort from age 14-22 in 1979 through age 47-55 in 2012. Using ordinal logistic regression, we test the selection hypothesis that overweight and obese adolescents were less likely to earn high school diplomas and bachelor's degrees. Then, controlling for selection with individual fixed effects, we estimate the causal effect of degree completion on BMI and obesity status. Among 18-year-old women, but not among men, being overweight or obese predicts lower odds of attaining higher levels of education. At age 47-48, higher education is associated with lower BMI, but 70-90% of the association is due to selection. Net of selection, a bachelor's degree predicts less than a 1 kg reduction in body weight, and a high school credential does not reduce BMI. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Marketing on television showcases less-healthful options, with emerging research suggesting movies promote similar products. Given the obesity epidemic, understanding advertising to youth should be a public health imperative. The objective of this study was to estimate youth impressions to food and beverages delivered through movies. Impressions were calculated by dividing US receipts annually into average movie ticket prices, then multiplying this by the number of brand appearances. Examination by ratings, product types and ages were conducted by Spearman rank correlation coefficient tests. Youth in the USA saw over 3 billion food, beverage or food-retail establishment (FRE) impressions on average, annually from 1996 to 2005. Those aged 12-18 viewed over half of all impressions, with PG-13-rated movies containing 61.5% of impressions. There were no significant trends in brand appearances by food, beverage or FRE impressions over the decade, although there was a decreasing trend in R-rated impressions for both foods (P< 0.01) and beverages (P< 0.01), but not FREs (P= 0.08). Movies promote billions of food and beverage impressions annually to youth. Given the public health crisis of obesity, future research should further investigate these trends, as well as the potential association of these unhealthy exposures in youth.

    Tobacco and obesity are leading contributors to mortality in the United States. Due to emerging changes in youth tobacco use, further examination of co-occurrence of these issues is warranted. This study examined associations between body mass index (BMI) and tobacco-product use and whether these varied by gender in a nationally representative sample of 12,416 Wave 1 (2013-2014) U.S. youth (12-17 years) from the Population Assessment of Tobacco and Health Study. Multivariable logistic regression analyses examined the odds of past 30-day tobacco-product use according to BMI. BMI was analyzed categorically using the Centers for Disease Control and Prevention (CDC) BMI-for-age weight status categories (underweight/healthy weight, overweight, and obese) and as a continuous variable. Youth classified as overweight or obese were not more likely to use any tobacco, cigarettes, e-cigarettes, any cigar, or hookah. However, youth who were obese were more likely to use smokeless tobacco (Adjusted Odds Ratio (AOR) = 1.68, 95% Confidence Interval (CI): 1.01, 2.81). There were no significant gender interactions for these associations. When BMI was analyzed continuously, a 5-unit and 10-unit increase was significantly associated with using any tobacco, cigarettes, any cigar, and smokeless tobacco. This linear association was supported by similar results for a log-transformed BMI variable. Findings suggest a continuum between weight increase and tobacco-product use among American youth. Clinicians should consider screening for tobacco use among youth who gain weight within any weight class, not just those considered overweight or obese. Copyright © 2018 Elsevier Ltd.

    Background Pediatric studies examining the association between obstructive sleep apnea (OSA) and insulin sensitivity/cardiometabolic risk are limited and conflicting. Objective To determine if cardiometabolic risk markers are increased among obese youth with obstructive sleep apnea as compared with their equally obese peers without OSA. Methods We performed a retrospective analysis of 96 patients (age 14.2 ± 1.4 years) who underwent polysomnography for suspected OSA. Fasting lipids, glucose, insulin, and hemoglobin A1c (HbA1c) were performed as part of routine clinical evaluation. Patients were categorized into two groups by degree of OSA as measured by the apnea hypopnea index (AHI): none or mild OSA (AHI < 5) and moderate or severe OSA (AHI ≥ 5). Results Despite similar degrees of obesity, patients with moderate or severe OSA had higher fasting insulin (p = 0.037) and homeostasis model assessment-insulin resistance [HOMA-IR (p = 0.0497)], as compared with those with mild or no OSA. After controlling for body mass index, there was a positive association between the AHI and log HOMA-IR (p = 0.005). There was a positive relationship between arousals plus awakenings during the polysomnography and fasting triglycerides. Conclusions OSA is linked with greater cardiometabolic risk markers in obese youth. PMID:24106092

    Objectives. We examined the relationship between fast-food restaurants near schools and obesity among middle and high school students in California. Methods. We used geocoded data (obtained from the 2002–2005 California Healthy Kids Survey) on over 500 000 youths and multivariate regression models to estimate associations between adolescent obesity and proximity of fast-food restaurants to schools. Results. We found that students with fast-food restaurants near (within one half mile of) their schools (1) consumed fewer servings of fruits and vegetables, (2) consumed more servings of soda, and (3) were more likely to be overweight (odds ratio [OR] = 1.06; 95% confidence interval [CI] = 1.02, 1.10) or obese (OR = 1.07; 95% CI = 1.02, 1.12) than were youths whose schools were not near fast-food restaurants, after we controlled for student- and school-level characteristics. The result was unique to eating at fast-food restaurants (compared with other nearby establishments) and was not observed for another risky behavior (smoking). Conclusions. Exposure to poor-quality food environments has important effects on adolescent eating patterns and overweight. Policy interventions limiting the proximity of fast-food restaurants to schools could help reduce adolescent obesity. PMID:19106421

    Evidence suggests that parenting attitudes are transmitted within families. However, limited research has examined this prospectively. The current prospective study examined direct effects of early maternal attitudes toward parenting (as measured at child age 4 by the Adult-Adolescent Parenting Inventory [AAPI]) on later youth parenting attitudes (as measured by the AAPI at youth age 18). Indirect effects via child maltreatment (physical abuse, sexual abuse, neglect, and emotional maltreatment), parent involvement, and youth functioning (internalizing and externalizing problems) were also assessed. Analyses were conducted on data from 412 families enrolled in the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). There were significant direct effects for three of the four classes of mother parenting attitudes (appropriate developmental expectations of children, empathy toward children, and appropriate family roles) on youth attitudes but not for rejection of punishment. In addition, the following indirect effects were obtained: Mother expectations influenced youth expectations via neglect; mother empathy influenced youth empathy via both parental involvement and youth externalizing problems; and mother rejection of punishment influenced youth rejection of punishment via youth internalizing problems. None of the child or family process variables, however, affected the link between mother and youth attitudes about roles. PMID:25113632

    Evidence is emerging that obesity-associated cardiovascular disorders (CVD) show variations across regions and ethnicities. However, it is unclear if there are distinctive patterns of abdominal obesity contributing to an increased CVD risk in South Asians. Also, potential underlying mechanistic pathways of such unique patterns are not comprehensively reported in South Asians. This review sets out to examine both. A comprehensive database search strategy was undertaken, namely, PubMed, Embase and Cochrane Library, applying specific search terms for potentially relevant published literature in English language. Grey literature, including scientific meeting abstracts, expert consultations, text books and government/non-government publications were also retrieved. South Asians have 3-5% higher body fat than whites, at any given body mass index. Additional distinctive features, such as South Asian phenotype, low adipokine production, lower lean body mass, ethno-specific socio-cultural and economic factors, were considered as potential contributors to an early age-onset of obesity-linked CVD risk in South Asians. Proven cost-effective anti-obesity strategies, including the development of ethno-specific clinical risk assessment tools, should be adopted early in the life-course to prevent premature CVD deaths and morbidity in South Asians.

    Objectives Explore the effects of a novel 12-week gardening, nutrition, and cooking intervention (“LA Sprouts”) on dietary intake, obesity parameters and metabolic disease risk among low-income, primarily Hispanic/Latino youth in Los Angeles. Methods Randomized control trial involving four elementary schools [2 randomized to intervention (172, 3rd–5th grade students); 2 randomized to control (147, 3rd–5th grade students)]. Classes were taught in 90-minute sessions once/week for 12 weeks. Data collected at pre- and post-intervention included dietary intake via food frequency questionnaire (FFQ), anthropometric measures [BMI, waist circumference (WC)], body fat, and fasting blood samples. Results LA Sprouts participants compared to controls had significantly greater reductions in BMI z-scores (−0.1 vs. −0.04, respectively; p=0.01) and WC (−1.2 vs. 0.1cm; p<0.001). Fewer LA Sprouts participants had the metabolic syndrome (MetSyn) after the intervention than before, while controls with MetSyn increased. LA Sprouts participants compared to controls increased dietary fiber intake (+3.4% vs. −16.5%; p=0.04). All participants decreased vegetable intake, but decreases were less in LA Sprouts than controls (−3.7% vs. −26.1%; p=0.04). Change in fruit intake did not differ between LA Sprouts and controls. Conclusions LA Sprouts was effective in reducing obesity and metabolic risk, however, additional larger and longer term studies are warranted. PMID:26909882

  20. Environmental influences on childhood obesity: ethnic and cultural influences in context.

    PubMed

    Kumanyika, Shiriki K

    2008-04-22

    Ethnicity is associated with differences in food-related beliefs, preferences, and behaviors, and cultural influences may contribute to the higher than average risk of obesity among children and youth in U.S. ethnic minority populations. However, cultural attitudes and beliefs are not the only potential source of ethnic variation in childhood obesity prevalence and should not be studied in isolation. Demographic, socio-structural, and environmental variables must also be considered. Available evidence indicates ethnic differences along several pathways that may increase risks of obesity development during gestation, infancy, childhood and adolescence. These include above-average prevalence of obesity in adult females and of maternal diabetes during pregnancy, parental attitudes and practices that may lead to overfeeding children, above-average levels of consumption of certain high calorie foods and beverages, and inadequate physical activity. Environments with lower than average neighborhood availability of healthful foods and higher than average availability of fast food restaurants, along with exposure to ethnically targeted food marketing may contribute to reliance on high calorie foods and beverages, and these foods may be socially and culturally valued. Attitudes about and environmental contexts for physical activity are also relevant. Increasingly, it is acknowledged that individual behaviors and lifestyles, e.g. food choices or child feeding practices, are responsive to the ecological contexts in which they are practiced. Focusing attention on the fluid interactions of cultural influences with contextual factors, of recognized importance for the study of childhood undernutrition, can also lead to further understanding of how to address ethnic disparities in childhood obesity.

    Despite accumulating evidence of the important health benefits of bariatric surgery in morbidly obese patients in general, bariatric surgery outcomes are less clear in higher-risk, high-priority populations of patients with BMI ≥ 50 kg/m 2 . To help the Department of Veterans Affairs (VA) Health Services Research & Development Service (HSR&D) develop a research agenda, we conducted a rapid evidence review to better understand bariatric surgery outcomes in adults with BMI ≥ 50 kg/m 2 . We searched MEDLINE ® , the Cochrane Database of Systematic Reviews, the Cochrane Central Registry of Controlled Trials, and ClinicalTrials.gov through June 2016. We included trials and observational studies. We used pre-specified criteria to select studies, abstract data, and rate internal validity and strength of the evidence (PROSPERO registration number CRD42015025348). All decisions were completed by one reviewer and checked by another. Among 1892 citations, we included 23 studies in this rapid review. Compared with usual care, one large retrospective VA study provided limited evidence that bariatric surgery can lead to increased mortality in the first year, but decreased mortality long-term among super obese veterans. Studies that compared different bariatric surgical approaches suggested some differences in weight loss and complications. Laparoscopic gastric bypass generally resulted in greater short-term proportion of excess weight loss than did other procedures. Duodenal switch led to greater long-term weight loss than did gastric bypass, but with more complications. The published literature that separates the super obese is insufficient for determining the precise balance of benefits and harms of bariatric surgery in this high-risk subgroup. Future studies should evaluate a more complete set of key outcomes with longer follow-up in larger samples of more broadly representative adults.

  2. Belief beyond the evidence: using the proposed effect of breakfast on obesity to show 2 practices that distort scientific evidence1234

    Brown, Andrew W; Bohan Brown, Michelle M

    2013-01-01

    Background: Various intentional and unintentional factors influence beliefs beyond what scientific evidence justifies. Two such factors are research lacking probative value (RLPV) and biased research reporting (BRR). Objective: We investigated the prevalence of RLPV and BRR in research about the proposition that skipping breakfast causes weight gain, which is called the proposed effect of breakfast on obesity (PEBO) in this article. Design: Studies related to the PEBO were synthesized by using a cumulative meta-analysis. Abstracts from these studies were also rated for the improper use of causal language and biased interpretations. In separate analyses, articles that cited an observational study about the PEBO were rated for the inappropriate use of causal language, and articles that cited a randomized controlled trial (RCT) about the PEBO were rated for misleadingly citing the RCT. Results: The current body of scientific knowledge indicates that the PEBO is only presumed true. The observational literature on the PEBO has gratuitously established the association, but not the causal relation, between skipping breakfast and obesity (final cumulative meta-analysis P value <10−42), which is evidence of RLPV. Four examples of BRR are evident in the PEBO literature as follows: 1) biased interpretation of one's own results, 2) improper use of causal language in describing one's own results, 3) misleadingly citing others’ results, and 4) improper use of causal language in citing others’ work. Conclusions: The belief in the PEBO exceeds the strength of scientific evidence. The scientific record is distorted by RLPV and BRR. RLPV is a suboptimal use of collective scientific resources.

    2014-01-01

    Obesity, diabetes, and metabolic syndrome are growing worldwide health concerns, yet their causes are not fully understood. Research into the etiology of the obesity epidemic is highly influenced by our understanding of the evolutionary roots of metabolic control. For half a century, the thrifty gene hypothesis, which argues that obesity is an evolutionary adaptation for surviving periods of famine, has dominated the thinking on this topic. Obesity researchers are often not aware that there is, in fact, limited evidence to support the thrifty gene hypothesis and that alternative hypotheses have been suggested. This review presents evidence for and against the thrifty gene hypothesis and introduces readers to additional hypotheses for the evolutionary origins of the obesity epidemic. Because these alternate hypotheses imply significantly different strategies for research and clinical management of obesity, their consideration is critical to halting the spread of this epidemic.

  4. Obesity and body image.

    PubMed

    Schwartz, Marlene B; Brownell, Kelly D

    2004-01-01

    Modern western culture emphasizes thinness, denigrates excess weight, and stigmatizes obese individuals, making it likely that obese people internalize these messages and feel badly about the physical presence that brands them. There is clear evidence that obesity is linked with poor body image, but not all obese persons suffer from this problem or are equally vulnerable. Risk factors identified thus far are degree of overweight, being female, and binge eating, with some evidence of risk increasing with early age of onset of obesity, race, and several additional factors. Treatments do exist for improving body image in overweight individuals. Key questions are how to identify those in need of body image intervention, how such programs can be integrated with weight loss treatments, and ultimately, how body image distress can be prevented.

    'feeling healthy' as a determinant of maintaining a healthy weight. Despite these beliefs, many teens had unrealistic and unhealthy perceptions of weight. Female participants were more concerned with weight than males, some to the point of obsession. Both males and females expressed a social stigma associated with overweight. Issues of guilt and diminished self-esteem were prevalent. When asked about the extensiveness of the problem of childhood overweight, the students indicated that a degree of familiarity with being overweight has developed and 'you just get used to [seeing] it.' Because of the rising rates of chronic disease in this region, a fear was evident in these youth about the increased risk of developing these conditions in those who are overweight. Experiences with family members with diabetes and cardiovascular disease fueled these concerns, which instilled a fear of becoming overweight in many of the students. Many perceptions of healthy weight and appropriate body size were shaped by the media and entertainment industry. Additionally, some participants admitted to performing unsafe practices to reduce body mass, such as very low calorie diets or fasting. Youth in rural Appalachia present similar perceptions about weight as other children; however, differences in perceived healthy lifestyle habits and a general acceptance of a higher average body weight present additional challenges to addressing the increasing problem of child overweight. Despite the relative isolation of many of these communities, the media has a profound impact on weight valuation that has been intertwined with school-based health education and cultural values of health. These data will provide valuable information for the development of obesity prevention programs in rural Appalachia.

    2012-05-01

    Obesity disproportionately affects African American (AA) children and adolescents and leads to an increased risk of adult chronic diseases. Eating few meals at home has been implicated as a cause of obesity among youth, but to our knowledge, previous studies have not specifically investigated this relationship in AA adolescents or looked at both the healthfulness and frequency of home meals in AA households. The objective of the present study was to investigate the relationship between home food preparation and adolescent BMI in a sample of 240 AA adolescents aged 10-15 y and their caregivers. Multiple linear regressions were used to model psychosocial characteristics, household factors, and adolescent and caregiver food preparation behaviors as predictors of adolescent BMI, and psychosocial and household factors as predictors of food preparation behavior. Adolescents in the sample had a mean BMI-for-age percentile of 70.4, and >90% of the sample families received at least one form of food assistance. Adolescent children of caregivers who used healthier cooking methods were more likely to use healthy cooking methods themselves (P = 0.02). Having more meals prepared by a caregiver was predictive of higher BMI-for-age percentile in adolescents (P = 0.02), but healthier cooking methods used by the caregiver was associated with reduced risk of adolescent overweight or obesity (P < 0.01). Meals prepared at home in AA households do not necessarily promote healthy BMI in youth. Family meals are a promising adolescent obesity prevention strategy, but it is important to target both frequency and healthfulness of meals prepared at home for effective health promotion in AA families.

    Obesity is a highly burdensome public health issue associated with premature death, multiple comorbid disabilities and staggering healthcare costs. Between 1980-2000, the prevalence of obesity among children and adolescents nearly tripled. Obesity subjects youth to social stigmatization and discrimination. These economic and personal burdens mandate targeted prevention and detection educational programs for all individuals at risk. The most cost-effective method of approaching this obesity epidemic is through education of health professionals. As part of an "Obesity Prevention in Pediatrics" curriculum, postgraduate-year (PGY)-2 residents first observed and then participated in the dietary evaluation and counseling of pediatric patients and their families. Attitudinal questionnaires, multiple-choice knowledge examinations and a pre-established checklist of desired skills and behaviors provided evaluation of the curriculum's effect on the participants' ability and willingness to manage actually obese or at-risk pediatric patients and their families. Attitudinal survey and knowledge test scores from control PGY-3 residents generally confirmed that their knowledge and counseling skills on obesity prevention and management were well below expectation. Following participation in the curriculum, study residents' knowledge tended to improve, as did their level of comfort in counseling obese and at-risk children, adolescents and their parents. Implementation of an "Obesity Prevention in Pediatrics" curriculum appears to improve participants' knowledge base as well as their skills and level of personal comfort in the recognition, evaluation and management, including counseling, of both obese and at-risk pediatric patients and their families.

    2009-01-01

    A qualitative assessment was completed of overweight/obese youths' perceptions of the meaning of "healthy body weight," barriers and facilitators to healthy body weight attainment, and what would effectively enhance and support their healthy body weight behaviours. This qualitative study targeted a sample of overweight and obese youth, aged 14 to 16 years. An experienced interviewer conducted 11 in-depth interviews. Interviews were audio-recorded and transcribed verbatim. Three qualitative researchers conducted independent and simultaneous inductive content analysis to facilitate confirmability. Data trustworthiness was supported via member checking, peer debriefing, and reflexive journalling. Most participants characterized healthy body weight as a combination of healthy eating and regular physical activity. Some included a psychological dimension in the definition. Perceived facilitators of a healthy body weight included family support, access to nutritious food at home, physical activity encouragement, and a physical activity environment at school. Perceived barriers included lack of family support, a poor nutrition environment, an unsupportive school environment, time, self-esteem, and bullying. Participants identified preferences for an intervention that would include opportunities for unstructured coeducational recreational activities, coeducational nutrition education sessions, and a gender-specific discussion forum. Participants provided a wealth of information to form the foundation of future youth-focused efficacious healthy body weight interventions.

    The authors use examples of youth civic engagement from Chile, South Africa, Central/Eastern Europe, and the United States--and also emphasize diversities among youth from different subgroups within countries--to illustrate common elements of the civic domain of youth development. These include the primacy of collective activity for forming political identities and ideas and the greater heterogeneity of civic compared to other discretionary activities, the groupways or accumulated opportunities for acting due to the groups (social class, gender, ethnic, caste, etc.) to which a young person belongs, and the role of mediating institutions (schools, community-based organizations, etc.) as spaces where youths' actions contribute to political stability and change.

    PubMed

    2018-03-01

    Rising rates of childhood obesity over the past 2 decades have spurred a number of public- and private-sector initiatives aimed at halting or even reversing this trend. Recognizing common interests in this issue, the Centers for Disease Control and Prevention, NIH, and the Robert Wood Johnson Foundation began conversations about creating a formal collaboration aimed at accelerating efforts to address childhood obesity by coordinating research agendas and providing support for evidence-building activities. The National Collaborative on Childhood Obesity Research (NCCOR) was launched in February 2009, and the U.S. Department of Agriculture joined in 2010. Using the model provided by other previously successful collaborations, such as the Youth Tobacco Cessation Collaborative, NCCOR has emphasized several principles suggested by Petrovich as key elements for successful partnerships: (1) delineate a common purpose by identifying key knowledge gaps in the field; (2) create a shared identity around that common purpose; (3) develop structures for democratic and respectful collaboration so as to strategically coordinate efforts for maximum national impact; (4) identify effective leaders capable of articulating challenges in the field and inspiring a commitment of minds and the resolve to address identified needs; (5) facilitate continuous knowledge exchange and synthesis to keep the field informed; and (6) support assessment of progress and feedback loops for ensuring continual progress. This paper examines how NCCOR has used these principles to help build the field of research, evaluation, and surveillance for childhood obesity prevention and management. Published by Elsevier Inc.

    Context Sex education/family life education (FLE) has been one of the highly controversial issues in Indian society. Due to increasing incidences of HIV/AIDS, RTIs/STIs and teenage pregnancies, there is a rising need to impart sex education. However, introducing sex education at school level always received mixed response from various segments of Indian society. Data and Methods We attempt to understand the expectations and experiences of youth regarding family life education in India by analysing the data from District Level Household and Facility Survey (DLHS-3: 2007–08) and Youth Study in India (2006–07). We used descriptive methods to analyse the extent of access to FLE and socio demographic patterning among Indian youth. Results and Discussions We found substantial gap between the proportion of youth who perceived sex education to be important and those who actually received it, revealing considerable unmet need for FLE. Youth who received FLE were relatively more aware about reproductive health issues than their counterparts. Majority among Indian youth, irrespective of their age and sex, favoured introduction of FLE at school level, preferably from standard 8th onwards. The challenge now is to develop a culturally-sensitive FLE curriculum acceptable to all sections of society. PMID:23951197

    Weight-based bullying is a prevalent problem among youth with overweight and obesity, but remains neglected in existing policy-level strategies to address youth bullying. Parental support is an influential catalyst motivating political will for policy decisions affecting youth, but has received limited research attention. To assess levels of, and predictors of, parental support for school-based policies and state/federal legal measures to address weight-based bullying in 2014 and 2015. Identical online questionnaires were completed by two independent national samples of parents in 2014 and 2015 (N = 1804). Parental support for all policy actions was high (at least 81%) and significantly increased from 2014 to 2015 for legal measures that would a) require state anti-bullying laws to add protections against weight-based bullying, and b) enact a federal anti-bullying law that includes weight-based bullying. These findings can inform policy discourse about remedies for youth bullying, and suggest that parental support for improved legal protections against weight-based bullying is present, consistent, and strong. © 2016 World Obesity Federation.

  15. Social influence and obesity.

    PubMed

    Hammond, Ross A

    2010-10-01

    To review a selection of research published in the last 12 months on the role of social influence in the obesity epidemic. Recent papers add evidence to previous work linking social network structures and obesity. Social norms, both eating norms and body image norms, are identified as one major source of social influence through networks. Social capital and social stress are additional types of social influence. There is increasing evidence that social influence and social network structures are significant factors in obesity. Deeper understanding of the mechanisms of action and dynamics of social influence, and its link with other factors involved in the obesity epidemic, is an important goal for further research.

    The Ho Chi Minh Youth cohort study aimed to assess the change in nutritional status; indicators of adiposity; diet; physical activity and sedentary behaviours; home, neighbourhood and school microenvironments and their complex relationships in adolescents in urban areas of Ho Chi Minh City. Prospective 5-year cohort. Systematic random sampling was used to select 18 schools in urban districts. Children were followed up over 5 years with an assessment in each year. Consent, from both adolescents and their parents, was required. At baseline, 759 students were recruited into the cohort, and of these students, 740 remained in the cohort for the first round, 712 for the second round, 630 for the third round and 585 for the last round of follow-up. Anthropometric measurements were taken using established guidelines. Six main groups of exposure factors including dietary intake and behaviours, physical activity and sedentary behaviours, family social and physical environment, school environment, socioeconomic status and parental characteristics were measured. Retention rate was high (77%). Within 5-year period, the prevalence of combined overweight and obesity using International Obesity Task Force cut-off values increased from 14.2% to 21.8%. Time spent on physical activity decreased significantly in the 5-year period from 87 to 50 min/day. Time spent on sedentary behaviours increased in the 5-year period from 512 to 600 min/day. The complete data analysis of this cohort study will allow a full exploration of the role of environmental and lifestyle behaviours on adolescent overweight and obesity and also identify the factors most strongly associated with excess weight gain and the appearance of overweight and obesity in different age groups of adolescents from this large city in Vietnam.

    In response to recent calls for programs that can prevent multiple types of youth violence, the current study examined whether Safe Dates, an evidence-based dating violence prevention program, was effective in preventing other forms of youth violence. Using data from the original Safe Dates randomized controlled trial, this study examined (1) the effectiveness of Safe Dates in preventing peer violence victimization and perpetration and school weapon carrying 1 year after the intervention phase was completed and (2) moderation of program effects by the sex or race/ethnicity of the adolescent. Ninety percent (n = 1,690) of the eighth and ninth graders who completed baseline questionnaires completed the 1-year follow-up assessment. The sample was 51 % female and 26 % minority (of whom 69 % was black and 31 % was of another minority race/ethnicity). There were no baseline treatment group differences in violence outcomes. Treatment condition was significantly associated with peer violence victimization and school weapon carrying at follow-up; there was 12 % less victimization and 31 % less weapon carrying among those exposed to Safe Dates than those among controls. Treatment condition was significantly associated with perpetration among the minority but not among white adolescents; there was 23 % less violence perpetration among minority adolescents exposed to Safe Dates than that among controls. The observed effect sizes were comparable with those of other universal school-based youth violence prevention programs. Implementing Safe Dates may be an efficient way of preventing multiple types of youth violence.

    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.

    The limited success of youth violence prevention interventions suggests that effective prevention needs to address causes at multiple levels of analysis and empower youth in developing and implementing prevention programs. In this article, we review published studies of youth violence prevention efforts that engage youth in developing or implementing violence prevention activities. The reviewed studies suggest the promise of youth empowerment strategies and the need for systematic outcome studies of empowerment programs. After reviewing empowerment theory applied to youth violence prevention programs, we present a case study of the Youth Empowerment Solutions (YES) for Peaceful Communities program. YES engages middle-school youth in an after-school and summer program that includes a culturally tailored character development curriculum and empowers the youth to plan and implement community improvement projects with assistance from adult neighborhood advocates. The case study focuses on outcome evaluation results and presents evidence of the YES program effects on community-level outcomes (eg, property improvements, violent crime incidents) and on individual-level outcomes (eg, conflict avoidance, victimization). The literature review and the case study suggest the promise of engaging and empowering youth to plan and implement youth violence prevention programs.

    Evidence suggests that parenting attitudes are transmitted within families. However, limited research has examined this prospectively. The current prospective study examined direct effects of early maternal attitudes toward parenting (as measured at child age 4 by the Adult-Adolescent Parenting Inventory [AAPI]) on later youth parenting attitudes (as measured by the AAPI at youth age 18). Indirect effects via child maltreatment (physical abuse, sexual abuse, neglect, and emotional maltreatment), parent involvement, and youth functioning (internalizing and externalizing problems) were also assessed. Analyses were conducted on data from 412 families enrolled in the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). There were significant direct effects for three of the four classes of mother parenting attitudes (appropriate developmental expectations of children, empathy toward children, and appropriate family roles) on youth attitudes but not for rejection of punishment. In addition, the following indirect effects were obtained: Mother expectations influenced youth expectations via neglect; mother empathy influenced youth empathy via both parental involvement and youth externalizing problems; and mother rejection of punishment influenced youth rejection of punishment via youth internalizing problems. None of the child or family process variables, however, affected the link between mother and youth attitudes about roles. © The Author(s) 2014.

    Young obese youth are generally stronger than lean youth. This has been linked to the loading effect of excess body mass, acting as a training stimulus comparable to strength training. Whether this triggers specific adaptations of the muscle architecture (MA) and voluntary activation (VA) that could account for the higher strength of obese subjects remains unknown. MA characteristics (that is, pennation angle (PA), fascicle length (FL) and muscle thickness (MT)) and muscle size (that is, anatomical cross-sectional area (ACSA)) of the knee extensor (KE) and plantar flexor (PF) muscles were evaluated in 12 obese and 12 non-obese adolescent girls (12-15 years). Maximal isometric torque and VA of the KE and PF muscles were also assessed. Results revealed higher PA (P<0.05), greater MT (P<0.001), ACSA (P<0.01), segmental lean mass (P<0.001) and VA (P<0.001) for KE and PF muscles in obese girls. Moreover, obese individuals produced a higher absolute torque than their lean counterparts on the KE (224.6±39.5 vs 135.7±32.7 N m, respectively; P<0.001) and PF muscles (73.3±16.5 vs 44.5±6.2 N m; P<0.001). Maximal voluntary contraction (MVC) was correlated to PA for the KE (r=0.46-0.57, P<0.05-0.01) and PF muscles (r=0.45-0.55, P<0.05-0.01). MVC was also correlated with VA (KE: r=0.44, P<0.05; PF: r=0.65, P<0.001) and segmental lean mass (KE: r=0.48, P<0.05; PF: r=0.57, P<0.01). This study highlighted favorable muscular and nervous adaptations to obesity that account for the higher strength of obese youth. The excess of body mass supported during daily activities could act as a chronic training stimulus responsible for these adaptations.

    The aim of this communication is to provide some evidence linking the overweight/obesity and their impacts on different dimensions of health. We reviewed the related studies published from 1990 up till now through PubMed Central/Medline, which provide evidence linking obesity with health related issues. It is a risk factor for metabolic disorders and leads to serious health consequences for individuals and burden for the health care system as a whole. Literature search showed that it is related to at least 18 co-morbidities which are attributable to overweight and obesity. Moreover obese individuals more often suffer from significant joint pains, disorders and it also has social as well as psychological impairments. It is high time that countries facing the problems of obesity initiate some intervention measures to monitor and control this growing epidemic. PMID:25878654

    Suicide is currently the second leading cause of death in the U.S. among youth ages 10 to 24. Sexual and gender minority (SGM) youth face heightened risk for suicide and report greater odds of attempting suicide than their heteronormative peers. Contributing factors of experience, which are distinctly different from the experiences of heteronormative youth, place SGM youth at heightened risk for suicide. While interventions aimed at addressing suicide risk factors for all youth are being implemented and many have proven effective in the general population, no evidence-based intervention currently exists to reduce suicide risk within this special population. This perspective article discusses this need and proposes the development of an evidence-based suicide risk reduction intervention tailored to SGM youth. Creating a supportive school climate for SGM youth has been shown to reduce suicide risk and may provide protective effects for all youth while simultaneously meeting the unique needs of SGM youth.

    We investigated, in a sample of 112 unemployed parents of adolescents aged 10-19 years, the links between parental distress and change in youth emotional problems related to parental unemployment, and the moderation roles of parent-youth relationship and financial deprivation. Data were analyzed using descriptive statistics and correlations. Further, simple moderation, additive moderation, and moderated moderation models of regression were performed to analyze the effects of parental distress, parent-youth relationship and financial deprivation in predicting change in youth emotional problems related to parental unemployment. Results show that parental distress moderated by parent-youth relationship predicted levels of change in youth emotional problems related to parental unemployment. This study provides evidence that during job loss, parental distress is linked to youth emotional well-being and that parent-youth relationships play an important moderation role. This raises the importance of further researching parental distress impacts on youth well-being, especially during periods of high unemployment rates.

    To provide an in-depth analysis of the relationship between obesity and fast-food consumption by comparing urban obese and normal-weight Saudi Arabian children. A multicentre cross-sectional study was conducted from December 2015 to March 2016. Participants were divided into two groups (normal weight and obese) and further stratified by sex. Groups were randomly selected using a multistage stratified cluster-sampling technique. A self-paced questionnaire was used to collect data relating to food consumption. Weight height and waist circumference were measured and bioelectrical impedance analysis was performed in all children. Capital of Saudi Arabia, Riyadh. Children aged 9·00-11·99 years (n 1023). Compared with normal-weight groups, intake frequency of fast food/week was higher among the obese groups (P<0·001), irrespective of fast-food consumption outside (P<0·001) or inside (P<0·001) the home; and larger portion sizes were preferred in obese groups (P<0·001). Families eating fast-food meals together was a protective factor against obesity (OR; 95 % CI: 2·67; 1·44, 4·96, P<0·001), with similar results for families ordering from a 'healthy meals menu' for their children (1·90; 1·24, 2·90, P=0·002). Taste of fast foods (P=0·021), child-friendly menu (P=0·020) and meal cost (P<0·001) were identified as main reasons why parents took their children to fast-food restaurants; these data were replicated for parents with obese boys, but not girls. Development of effective interventions to reduce fast-food consumption in Saudi Arabian schoolchildren requires greater research-based evidence of fast-food consumption habits and practices associated with increased childhood obesity.

    Re-evaluation of adult obesity thresholds in some ethnic groups has led to the questioning of childhood obesity thresholds. An expert group was convened to examine the representativeness of childhood obesity definitions, evidence for ethnic differences in body composition in UK children and the extent of misclassification of adiposity by current body mass index (BMI) thresholds in south Asian and black groups. The group concluded that the current International Obesity Task Force (IOTF) definitions remained the most appropriate for use in the United Kingdom, but further research was needed on the relationship of body shape, fat mass, metabolic markers and ethnicity in children and adolescents.

    2015-02-01

    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.

    Youth aging out of foster care face a challenging road to independence. Following exposure to myriad risk factors such as abuse, neglect, parental substance use, and severe housing mobility, supportive services decrease upon exit from care, often increasing risk for substance use, homelessness, and unemployment. Although tobacco use is also highly prevalent, little attention has been paid to screening, assessment, and treatment of tobacco use in this vulnerable group. The current study (N = 116) reports on tobacco use prevalence, consequences, and co-occurrence with other substances in a sample of youth (ages 18 to 19) exiting the foster care system. In the face of an overall decrease in tobacco use among general population adolescents and young adults, results suggest disproportionate levels of lifetime, recent, and daily use among foster youth. Prevalence of recent tobacco use (46%) is nearly triple national rates, while daily smoking (32%) is almost four times that of general population young adults. Tobacco users were more likely than non-users to drink (70% vs. 40%) and to smoke marijuana (72% vs. 25%). We strongly encourage researchers and practitioners to increase attention to this tobacco-related health disparity. PMID:26478645

    Hemoglobin A1c (HbA1c) is increasingly performed over the oral glucose tolerance test (OGTT) as the initial screening test for type 2 diabetes in youth. However, the optimal strategy for identifying type 2 diabetes in youth remains controversial. Alternate glycemic markers have been proposed as potentially useful tools for diabetes screening. We examined the relationships among fructosamine (FA), glycated albumin (GA), and 1,5-anhydroglucitol (1,5-AG) with traditional screening tests, HbA1c and OGTT. Youth 10-18 yrs, BMI ≥85th‰, and HbA1c <7.5% had a single visit with measurement of HbA1c, 1,5-AG, FA, GA, and a standard OGTT. Distributions of FA, GA, and 1,5-AG by HbA1c and 2-hour glucose (2hG) categories were compared. Receiver operating characteristic (ROC)-curves were generated to determine the cut points at which alternate markers maximized sensitivity and specificity for predicting prediabetes and diabetes. One hundred and seventeen, 62% female, 59% Hispanic, 22% White, 17% black, median 14.1 yr, and body mass index (BMI) z-score 2.3 participated. Median values of each alternate marker differed significantly between prediabetes and diabetes HbA1c and 2hG categories (p < 0.017). Only GA medians differed (p = 0.006) between normal and prediabetes HbA1c. Area under the receiver operating characteristic curves (ROC-AUCs) for alternate markers as predictors of prediabetes (0.5-0.66) were low; however, alternate marker ROC-AUCs for identifying diabetes (0.82-0.98) were excellent. Although the alternate markers were poor predictors of prediabetes, they all performed well predicting diabetes by 2hG and HbA1c. Whereas the usefulness of these markers for identifying prediabetes is limited, they may be useful in certain scenarios as second line screening tools for diabetes in overweight/obese youth. © 2015 John Wiley & Sons A/S.

    OBJECTIVE To determine the frequency of islet cell autoimmunity in youth clinically diagnosed with type 2 diabetes and describe associated clinical and laboratory findings. RESEARCH DESIGN AND METHODS Children (10–17 years) diagnosed with type 2 diabetes were screened for participation in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study. Measurements included GAD-65 and insulinoma-associated protein 2 autoantibodies using the new National Institute of Diabetes and Digestive and Kidney Diseases/National Institutes of Health (NIDDK/NIH) standardized assays, a physical examination, and fasting lipid, C-peptide, and A1C determinations. RESULTS Of the 1,206 subjects screened and considered clinically to have type 2 diabetes, 118 (9.8%) were antibody positive; of these, 71 (5.9%) were positive for a single antibody, and 47 were positive (3.9%) for both antibodies. Diabetes autoantibody (DAA) positivity was significantly associated with race (P < 0.0001), with positive subjects more likely to be white (40.7 vs. 19%) (P < 0.0001) and male (51.7 vs. 35.7%) (P = 0.0007). BMI, BMI z score, C-peptide, A1C, triglycerides, HDL cholesterol, and blood pressure were significantly different by antibody status. The antibody-positive subjects were less likely to display characteristics clinically associated with type 2 diabetes and a metabolic syndrome phenotype, although the range for BMI z score, blood pressure, fasting C-peptide, and serum lipids overlapped between antibody-positive and antibody-negative subjects. CONCLUSIONS Obese youth with a clinical diagnosis of type 2 diabetes may have evidence of islet autoimmunity contributing to insulin deficiency. As a group, patients with DAA have clinical characteristics significantly different from those without DAA. However, without islet autoantibody analysis, these characteristics cannot reliably distinguish between obese young individuals with type 2 diabetes and those with autoimmune diabetes. PMID

    An important theory of attention suggests that there are three separate networks that execute discrete cognitive functions: alerting, orienting and conflict networks. Recent studies showed that there was a dysfunction of attention in Internet Addiction. In order to investigate the underlying mechanism of attention dysfunction in Internet Addiction, we recorded performance related to the Attentional Network Test (ANT) in youth. The ANT, a behavioral assay of the functional integrity of attention networks, was used to examine the performance in Internet Addiction and healthy controls. Performance on the ANT clearly differentiated the participants with and without Internet Addiction in terms of mean reaction times (RTs). Compared with control group, the Internet Addiction group detected targets more slowly and this effect was evident only for spatial cue condition. The Internet Addiction group demonstrated deficits in the orienting network in terms of slower RT. There was no demonstration of a deficit in both the alerting and conflict network in Internet Addiction on this task. The youth with Internet Addiction demonstrated deficits in the orienting network but normal functioning of the alerting and conflict attention networks. Copyright © 2017 Elsevier B.V.

    Since pathophysiologic evidence has been raised to suggest that obesity could facilitate an allergic reaction, obesity has been known as an independent risk factor for allergic disease such as asthma. However, the relationship between sedentary behavior and lifestyle which could lead to obesity, and those allergic diseases remains unclear. We analyzed the relations between physical activity, including sitting time for study, sitting time for leisure and sleep time, and obesity, asthma, allergic rhinitis, and atopic dermatitis using the Korea Youth Risk Behavior Web-based Survey, which was conducted in 2013. Total 53769 adolescent participants (12 through 18 years old) were analyzed using simple and multiple logistic regression analyses with complex sampling. Longer sitting time for study and short sitting time for leisure were associated with allergic rhinitis. High physical activity and short sleep time were associated with asthma, allergic rhinitis, and atopic dermatitis. Underweight was negatively associated with atopic dermatitis, whereas overweight was positively correlated with allergic rhinitis and atopic dermatitis. High physical activity, and short sleep time were associated with asthma, allergic rhinitis, and atopic dermatitis. © Copyright: Yonsei University College of Medicine 2017

    Sedentary behaviour (SB) has emerged as a potential risk factor for metabolic health in youth. Knowledge on the determinants of SB in youth is necessary to inform future intervention development to reduce SB. A systematic review was conducted to identify predictors and determinants of SB in youth. Pubmed, Embase, CINAHL, PsycINFO and Web of Science were searched, limiting to articles in English, published between January 2000 and May 2014. The search strategy was based on four key elements and their synonyms: (a) sedentary behaviour, (b) determinants, (c) types of sedentary behaviours, (d) types of determinants. The full protocol is available from PROSPERO (PROSPERO 2014:CRD42014009823). Cross-sectional studies were excluded. The analysis was guided by the socio-ecological model. 37 studies were selected out of 2654 identified papers from the systematic literature search. Most studies were conducted in Europe (n = 13), USA (n = 11), and Australia (n = 10). The study quality, using the Qualsyst tool, was high with a median of 82% (IQR: 74-91%). Multiple potential determinants were studied in only one or two studies. Determinants were found at the individual, interpersonal, environmental and policy level but few studies examined a comprehensive set of factors at different levels of influences. Evidence was found for age being positively associated with total SB, and weight status and baseline assessment of screen time being positively associated with screen time (at follow-up). A higher playground density and a higher availability of play and sports equipment at school were consistently related to an increased total SB, although these consistent findings come from single studies. Evidence was also reported for the presence of safe places to cross roads and lengthening morning and lunch breaks being associated with less total SB. Future interventions to decrease SB levels should especially target children with overweight or obesity and should start at a

    The purpose of this study was to examine the association of knee injuries with subsequent changes in body mass index and body composition during maturation in young females. A prospective longitudinal study design was employed to evaluate young females active in soccer or basketball (N=862). Participants who completed at least 1-year follow-up to provide consecutive annual measures of BMIZ and %fat were included in the study analysis to determine the effect of knee injuries on the trajectory of these obesity markers in youth. Of the 71 reported knee injuries, 12 (17%) occurred in athletes at the prepubertal stage, 24 (34%) in athletes at the pubertal stage, and 35 (49%) in postpubertal athletes. Controlling for the effects of maturation, female athletes who reported knee injury demonstrated a greater yearly increase in BMIZ (LS means and 95% CI for the injured group=0.039 (-0.012 to 0.089), for the non-injured group=-0.019 (-0.066 to 0.029), and group difference=0.057 (0.005 to 0.11), p=0.03) and in %body fat (LS means and 95% CI for the injured group=1.05 (0.45 to 1.65), for the non-injured group=0.22 (-0.21 to 0.064), and group difference=0.83 (0.21 to 1.45), p=0.009), compared to those without knee injuries. This indicates that the athletes with knee injuries will increase their body mass index percentile by up to 5 units more than someone of the same age without an injury, and in body fat by up to 1.5%, compared to their non-injured peers. The present findings indicate that knee injury during the growing years may be associated with unfavourable changes in body composition. Published by the BMJ Publishing Group Limited.

    Recent findings suggest that the mental health costs of unemployment are related to both short- and long-term mental health scars. The main policy tools for dealing with young people at risk of labor market exclusion are Active Labor Market Policy programs for youths (youth programs). There has been little research on the potential effects of participation in youth programs on mental health and even less on whether participation in such programs alleviates the long-term mental health scarring caused by unemployment. This study compares exposure to open youth unemployment and exposure to youth program participation between ages 18 and 21 in relation to adult internalized mental health immediately after the end of the exposure period at age 21 and two decades later at age 43. The study uses a five wave Swedish 27-year prospective cohort study consisting of all graduates from compulsory school in an industrial town in Sweden initiated in 1981. Of the original 1083 participants 94.3% of those alive were still participating at the 27-year follow up. Exposure to open unemployment and youth programs were measured between ages 18-21. Mental health, indicated through an ordinal level three item composite index of internalized mental health symptoms (IMHS), was measured pre-exposure at age 16 and post exposure at ages 21 and 42. Ordinal regressions of internalized mental health at ages 21 and 43 were performed using the Polytomous Universal Model (PLUM). Models were controlled for pre-exposure internalized mental health as well as other available confounders. Results show strong and significant relationships between exposure to open youth unemployment and IMHS at age 21 (OR = 2.48, CI = 1.57-3.60) as well as at age 43 (OR = 1.71, CI = 1.20-2.43). No such significant relationship is observed for exposure to youth programs at age 21 (OR = 0.95, CI = 0.72-1.26) or at age 43 (OR = 1.23, CI = 0.93-1.63). A considered and consistent active labor

    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.

  2. International Youth Justice Systems: Promoting Youth Development and Alternative Approaches: A Position Paper of the Society for Adolescent Health and Medicine.

    2016-10-01

    Youth incarceration is an international public health concern among developed and developing countries. Worldwide, youth are held in incarceration, detention, and other secure settings that are inappropriate for their age and developmental stages, jeopardizing their prosocial development, and reintegration into society. Youth incarceration lacks evidence and cost-effectiveness. The well-being of youth is a key indicator of the welfare of families, communities, and society at large; therefore, the Society for Adolescent Health and Medicine (SAHM) supports a paradigm shift in the role of the justice system as it relates to treatment of youth. SAHM recommends justice systems focus greater attention and resources on identifying and reducing the antecedents of high-risk and criminal behaviors, recognizing the rights and freedom of young persons, and prioritizing the well-being of youth over punitive measures that may harm and disrupt healthy adolescent development. SAHM supports the following positions: (1) incarceration is a last option for selected offenders who have committed the most serious violent crimes and are unable to remain safely in the community; (2) youth justice policies, programs, and practices affecting youth be evidence based and trauma informed; (3) youth justice policies, programs, and practices must incorporate research and ongoing program evaluation; (4) youth justice policies shall protect the privacy and dignity of children younger than 18 years; and (5) health care professionals and media will promote positive portrayals of youth in healthy relationships within their communities and reduce representations and images of youth that are negative, violent, deviant, and threatening.

    cannot be primarily attractive to youth versus adults. But we do not yet have a sound scientific tool to assess what would be primarily attractive to youth. This manuscript uses a new tool, the CAY index, and two large, nationally representative datasets of youth and adult drinking patterns and shows that alcohol brands’ use of such content in their advertisements is not associated with adult brand consumption but is positively associated with youth brand consumption over and above the influence of adult brand preferences. This is critical evidence for supporting revised industry guidelines in order to protect youth from the effect of advertising on underage drinking. PMID:29780765

    The purpose of the study is to examine the associations of youth physical activity and screen time with weight status and cardiorespiratory fitness in children and adolescents, separately, utilizing a nationally representative sample. A total of 1,113 participants (692 children aged 6–11 yrs; 422 adolescents aged 12–15 yrs) from the 2012 NHANES National Youth Fitness Survey. Participants completed physical activity and screen time questionnaires, and their body mass index and cardiorespiratory fitness (adolescents only) were assessed. Adolescents completed additional physical activity questions to estimate daily MET minutes. Children not meeting the screen time guideline had 1.69 times the odds of being overweight/obese compared to those meeting the screen time guideline, after adjusting for physical activity and other control variables. Among adolescent, screen time was significantly associated with being overweight/obese (odds ratio = 1.82, 95% confidence interval: 1.06–3.15), but the association attenuated toward the borderline of being significant after controlling for physical activity. Being physically active was positively associated with cardiorespiratory fitness, independent of screen time among adolescents. In joint association analysis, children who did not meet physical activity nor screen time guidelines had 2.52 times higher odds of being overweight/obese than children who met both guidelines. Adolescents who did not meet the screen time guideline had significantly higher odds ratio of being overweight/obese regardless of meeting the physical activity guideline. Meeting the physical activity guideline was also associated with cardiorespiratory fitness regardless of meeting the screen time guideline in adolescents. Screen time is a stronger factor than physical activity in predicting weight status in both children and adolescents, and only physical activity is strongly associated with cardiorespiratory fitness in adolescents.

    PubMed

    Casanello, Paola; Krause, Bernardo J; Castro-Rodríguez, José A; Uauy, Ricardo

    Current evidence supports the notion that exposure to various environmental conditions in early life may induce permanent changes in the epigenome that persist throughout the life-course. This article focuses on early changes associated with obesity in adult life. A review is presented on the factors that induce changes in whole genome (DNA) methylation in early life that are associated with adult onset obesity and related disorders. In contrast, reversal of epigenetic changes associated with weight loss in obese subjects has not been demonstrated. This contrasts with well-established associations found between obesity related DNA methylation patterns at birth and adult onset obesity and diabetes. Epigenetic markers may serve to screen indivuals at risk for obesity and assess the effects of interventions in early life that may delay or prevent obesity in early life. This might contribute to lower the obesity-related burden of death and disability at the population level. The available evidence indicates that epigenetic marks are in fact modifiable, based on modifications in the intrauterine environment and changes in food intake, physical activity and dietary patterns patterns during pregnancy and early years of adult life. This offers the opportunity to intervene before conception, during pregnancy, infancy, childhood, and also in later life. There must be documentation on the best preventive actions in terms of diet and physical activity that will modify or revert the adverse epigenetic markers, thus preventing obesity and diabetes in suceptible individuals and populations.

    Early signs of renal complications can be common in youths with type 1 diabetes (T1D). Recently, there has been an increasing interest in potential renal complications associated with obesity, paralleling the epidemics of this condition, although there are limited data in children. Obese children and adolescents present signs of early alterations in renal function similar to non-obese peers with T1D. Eighty-three obese (age: 11.6 ± 3.0 yr), 164 non-obese T1D (age: 12.4 ± 3.2 yr), and 71 non-obese control (age: 12.3 ± 3.2 yr) children and adolescents were enrolled in the study. Anthropometric parameters and blood pressure were measured. Renal function was assessed by albumin excretion rate (AER), serum cystatin C, creatinine and estimated glomerular filtration rate (e-GFR), calculated using the Bouvet's formula. Obese and non-obese T1D youths had similar AER [8.9(5.9-10.8) vs. 8.7(5.9-13.1) µg/min] and e-GFR levels (114.8 ± 19.6 vs. 113.4 ± 19.1 mL/min), which were higher than in controls [AER: 8.1(5.9-8.7) µg/min, e-GFR: 104.7 ± 18.9 mL/min]. Prevalence of microalbuminuria and hyperfiltration was similar between obese and T1D youths and higher than their control peers (6.0 vs. 8.0 vs. 0%, p = 0.02; 15.9 vs. 15.9 vs. 4.3%, p = 0.03, respectively). Body mass index (BMI) z-score was independently related to e-GFR (r = 0.328; p < 0.001), and AER (r = 0.138; p = 0.017). Hemoglobin A1c (HbA1c) correlated with AER (r = 0.148; p = 0.007) but not with eGFR (r = 0.041; p = 0.310). Obese children and adolescents show early alterations in renal function, compared to normal weight peers, and they have similar renal profiles than age-matched peers with T1D. © 2014 John Wiley & Sons A/S.

    Nonalcoholic fatty liver disease (NAFLD) has become a worldwide epidemic because of the greater prevalence of obesity. Despite implications for youth with severe mental disorders, little has been published in the psychiatric literature about this increasingly common medical comorbidity. The goals of this article are to: 1) provide an overview of the epidemiology and pathophysiology of NAFLD, including progression to nonalcoholic steatohepatitis (NASH); 2) describe two clinical cases illustrating difficulties faced in management; and 3) review screening recommendations, differential diagnosis, and monitoring and intervention approaches. A literature review was conducted, including guidelines and recommendations, with case presentations including case and control liver histology biopsy photographs. NAFLD in childhood and adolescence, as a precursor to NASH, progresses to fibrosis in a small percentage of youth, leading to risk for early onset cirrhosis and the need for transplantation. The cases presented raise concern that youth with severe mental health disorders, already at greater risk for obesity and its sequelae, may be at higher risk for progression to NASH, potentially because of greater rates of weight gain on top of overweight or obese status, and to liver metabolism changes from psychotropic medications favoring fat deposition. Patients with rapid weight gain into the overweight or obese categories, or who develop elevated liver transaminases that persist across 3-6 months, should be screened or referred for screening by their psychotropic-providing clinicians for early detection, diagnosis, and co-management by a pediatric gastroenterologist, to decrease risk of progression to NASH, which is reversible if early and sufficient lifestyle change results in significant weight loss. There is urgent need for controlled research on the relationships among weight gain, psychotropic medications, ultrasound and biopsy findings, and rates of progression to NAFLD and

    No cross-national studies have examined public perceptions about weight-based bullying in youth. To conduct a multinational examination of public views about (i) the prevalence/seriousness of weight-based bullying in youth; (ii) the role of parents, educators, health providers and government in addressing this problem and (iii) implementing policy actions to reduce weight-based bullying. A cross-sectional survey of adults in the United States, Canada, Iceland and Australia (N = 2866). Across all countries, weight-based bullying was identified as the most prevalent reason for youth bullying, by a substantial margin over other forms of bullying (race/ethnicity, sexual orientation and religion). Participants viewed parents and teachers as playing major roles in efforts to reduce weight-based bullying. Most participants across countries (77-94%) viewed healthcare providers to be important intervention agents. Participants (65-87%) supported government augmentation of anti-bullying laws to include prohibiting weight-based bullying. Women expressed higher agreement for policy actions than men, with no associations found for participants' race/ethnicity or weight. Causal beliefs about obesity were associated with policy support across countries. Across countries, strong recognition exists of weight-based bullying and the need to address it. These findings may inform policy-level actions and clinical practices concerning youth vulnerable to weight-based bullying. © 2015 World Obesity.

    The aim of this study is to determine whether access to fast food outlets and supermarkets is associated with overweight and obesity in New York City neighborhoods. We use a Bayesian ecologic approach for spatial prediction. Consistent with prior research, we find no association between fast food density and overweight or obesity. Consistent with prior research, we find that supermarket access has a salutary impact on overweight and obesity. Given the lack of empirical evidence linking fast food retailers with adverse health outcomes, policymakers should be encouraged to adopt policies that incentivize the establishment of supermarkets and the modification of existing food store markets and retailers to offer healthier choices. Reaching within neighborhoods and modifying the physical environment and public health prevention and intervention efforts based on the characteristics of those neighborhoods may play a key role in creating healthier communities.

    2015-02-01

    Evidence suggests that at a population level, childhood and adolescent obesity increase the long-term risk of chronic diseases such as type 2 diabetes and CVD. At an individual level, however, the metabolic consequences of obesity in youth vary immensely. Despite comparable BMI, some adolescents develop impaired glucose tolerance while others maintain normal glucose homeostasis. It has been proposed that the variation in the capacity to store lipid in the subcutaneous adipose tissue (SAT) may partially discriminate metabolically healthy from unhealthy obesity. In positive energy balance, a decreased capacity to expand SAT may drive lipid accumulation to visceral adipose tissue, liver and skeletal muscle. This state of lipotoxicity is associated with chronic low-grade inflammation, insulin resistance and dyslipidaemia. The present review examines the differential adipose tissue development and function in children and adolescents who exhibit metabolic dysregulation compared with those who are protected. Additionally, the role of manipulating dietary fat quality to potentially prevent and treat metabolic dysfunction in obesity will be discussed. The findings of the present review highlight the need for further randomised controlled trials to establish the effect of dietary n-3 PUFA on the metabolic phenotype of obese children and adolescents. Furthermore, using a personalised nutrition approach to target interventions to those at risk of, or those with established metabolic dysregulation may optimise the efficacy of modifying dietary fat quality.

    2013-01-01

    Background Sex and individual differences in biological maturity status can influence height, weight, and body fat. Thus, the rigorous control of these variables seems necessary for estimating overweight and obesity in adolescents. The aims of this study were to estimate the prevalence of overweight and obesity and over-fatness in Azorean adolescents and to examine the contributions of chronological age, sex, estimated maturity status, and cardiorespiratory fitness (CRF) to the risk of overweight and obesity and over-fatness. Methods The sample comprised 1,206 youth aged 11–15 years (626 boys and 580 girls) from the Azores Islands, Portugal. Body mass, stature, and skinfolds (triceps and subscapular) were measured. Body mass index (BMI) was calculated and percent fat was predicted from skinfolds. Age- and sex-specific IOTF cut-off values of the BMI defined nutritional status. Biological maturation was estimated as present height expressed as a percentage of predicted adult (mature) stature. The CRF was analyzed from the 20-m shuttle run test. Results The total prevalence rates of overweight/obesity and over-fatness were of 31% and 27%, respectively. Low CRF (unfit) and being average and advanced in maturity status were positively and significantly associated with overweight/obesity and with risk of being over-fatness in both sexes. Conclusions High prevalence rates of overweight/obesity and over-fatness were identified in Azorean youth, and low CRF and advanced biological maturation were positively associated with overweight/obesity and over-fatness in our sample of adolescents.

    In Hispanic children and adolescents, the prevalence of obesity and insulin resistance is considerably greater than in non-Hispanic white children. A low-glycemic load diet (LGD) has been proposed as an effective dietary intervention for pediatric obesity, but to our knowledge, no published study has examined the effects of an LGD in obese Hispanic children. We compared the effects of an LGD and a low-fat diet (LFD) on body composition and components of metabolic syndrome in obese Hispanic youth. Obese Hispanic children (7-15 y of age) were randomly assigned to consume an LGD or an LFD in a 2-y intervention program. Body composition and laboratory assessments were obtained at baseline and 3, 12, and 24 mo after intervention. In 113 children who were randomly assigned, 79% of both groups completed 3 mo of treatment; 58% of LGD and 55% of LFD subjects attended 24-mo follow-up. Compared with the LFD, the LGD decreased the glycemic load per kilocalories of reported food intakes in participants at 3 mo (P = 0.02). Both groups had a decreased BMI z score (P < 0.003), which was expressed as a standard z score relative to CDC age- and sex-specific norms, and improved waist circumference and systolic blood pressure (P < 0.05) at 3, 12, and 24 mo after intervention. However, there were no significant differences between groups for changes in BMI, insulin resistance, or components of metabolic syndrome (all P > 0.5). We showed no evidence that an LGD and an LFD differ in efficacy for the reduction of BMI or aspects of metabolic syndrome in obese Hispanic youth. Both diets decreased the BMI z score when prescribed in the context of a culturally adapted, comprehensive weight-reduction program.

    This paper elucidates the challenges surrounding the economics of some popular obesity-related policy proposals. Solid economic justifications for anti-obesity policies are often lacking, and evidence suggests policies like fat and soda taxes or restrictions on food stamp spending are unlikely to substantively affect obesity prevalence. In short, many of the same factors that make obesity such a complicated and multifaceted issue extend to the economic analysis of public health policies.

    2014-07-01

    Although physical activity has been considered as an important modifiable risk factor for obesity, the empirical evidence on the relationship between physical activity and obesity is mixed. Observational studies in the public health literature fail to account for time-invariant unobserved heterogeneity and dynamics of weight, leading to biased estimation of the effect of physical activity on obesity. To overcome this limitation, we propose dynamic fixed-effects models to account for unobserved heterogeneity bias and the dynamics of obesity. We use nationally representative longitudinal data on the cohort of adults aged 18-50 years in 1994/95 from Canada's National Population Health Survey and followed them over 16 years. Obesity is measured by BMI (body mass index). After controlling for a wide range of socio-economic factors, the impact of four alternative measures of leisure-time physical activity (LTPA) and work-related physical activity (WRPA) are analyzed. The results show that each measure of LTPA exerts a negative effect on BMI and the effects are larger for females. Our key results show that participation in LTPA exceeding 1.5 kcal/kg per day (i.e., at least 30 min of walking) reduces BMI by about 0.11-0.14 points in males and 0.20 points in females relative to physically inactive counterparts. Compared to those who are inactive at workplace, being able to stand or walk at work is associated with a reduction in BMI in the range of 0.16-0.19 points in males and 0.24-0.28 points in females. Lifting loads at workplace is associated with a reduction in BMI by 0.2-0.3 points in males and 0.3-0.4 points in females relative to those who are reported sedentary. Policies aimed at promotion of LTPA combined with WRPA like walking or climbing stairs daily would help reduce adult obesity risks. Copyright © 2014 Elsevier B.V. All rights reserved.

    Background Even though the obesity epidemic continues to grow in various parts of the world, recent reports have highlighted disparities in obesity trends across countries. There is little empirical evidence on the development and growth of obesity in Lebanon and other countries of the Eastern Mediterranean Region. Acknowledging the need for effective obesity preventive measures and for accurate assessment of trends in the obesity epidemic, this study aims at examining and analyzing secular trends in the prevalence of overweight and obesity over a 12-year period in Lebanon. Methods Based on weight and height measurements obtained from two national cross-sectional surveys conducted in 1997 and 2009 on subjects 6 years of age and older, BMI was calculated and the prevalence of obesity was determined based on BMI for adults and BMI z-scores for children and adolescents, according to WHO criteria. Age -and sex- adjusted odds ratios for overweight and obesity were determined, with the 1997 year as the referent category. Annual rates of change in obesity prevalence per sex and age group were also calculated. Results The study samples included a total of 2004 subjects in the 1997 survey and 3636 in the 2009 survey. Compared to 1997, mean BMI values were significantly higher in 2009 among all age and sex groups, except for 6–9 year old children. Whereas the prevalence of overweight appeared stable over the study period in both 6–19 year old subjects (20.0% vs. 21.2%) and adults aged 20 years and above (37.0% vs. 36.8%), the prevalence of obesity increased significantly (7.3% vs. 10.9% in 6–19 year olds; 17.4% vs. 28.2% in adults), with the odds of obesity being 2 times higher in 2009 compared to 1997, in both age groups (OR = 1.96, 95% CI:1.29-2.97 and OR = 2.01, 95% CI: 1.67-2.43, respectively). The annual rates of change in obesity prevalence ranged between +4.1% in children and adolescents and +5.2% in adults. Conclusion The study’s findings highlight an

    Available data on metabolically healthy obese (MHO) phenotype in children suggest that gender, puberty, waist circumference, insulin sensitivity, and other laboratory predictors have a role in distinguishing these children from metabolically unhealthy obese (MUO) youth. The goal of this study was to identify predictors of MHO phenotype and to analyze glucose and insulin metabolism during oral glucose tolerance test (OGTT) in MHO children. OGTT was performed in 244 obese children and adolescents aged 4.6-18.9 years. Subjects were classified as MHO in case of no fulfilled criterion of metabolic syndrome except anthropometry or as MUO (≥2 fulfilled criteria). Among the subjects, 21.7 % had MHO phenotype, and they were more likely to be female, younger, and in earlier stages of pubertal development, with lower degree of abdominal obesity. Insulin resistance was the only independent laboratory predictor of MUO phenotype (OR 1.59, CI 1.13-2.25), with 82 % sensitivity and 60 % specificity for diagnosing MUO using HOMA-IR cutoff point of ≥2.85. Although no significant differences were observed in glucose regulation, MUO children had higher insulin demand throughout OGTT, with 1.53 times higher total insulin secretion. Further research is needed to investigate the possibility of targeted treatment of insulin resistance to minimize pubertal cross-over to MUO in obese children. • Substantial proportion of the obese youth (21-68 %) displays a metabolically healthy (MHO) phenotype. • Gender, puberty, waist circumference, insulin sensitivity, and lower levels of uric acid and transaminases have a possible role in distinguishing MHO from metabolically unhealthy obese (MUO) children. • Insulin resistance was found to be the only significant laboratory predictor of MUO when adjusted for gender, puberty, and the degree of abdominal obesity. • Besides basal insulin resistance, MUO children were found to have a significantly higher insulin secretion throughout OGTT in

    The aim of this work is analyse perceptions, intentions and actions related with own proportions of body conections with assessment to actual weight and height proportions (BMI) children and youth from Polkowice. Material examination includes measurement from research conducted in autumn of 2008 of Polkowice (Lower Silesia). Refine material includes measurement and survey 816 pupils (362 boys and 454 girls) aged 10 - 15 of primary schools and secondary school. Body height and weight were measured and calculated on the basis of Body Mass Index (BMI). According to the international standards--cut off points for overweight and obesity by Cole et al. (2000). Estimate the frequency of overweight and obesity among the examined population. Some information about self-body proportions and activities undertaken to change them was obtained from a survey titled Youth Risk Behavior Survey (YRBS). The frequency of overweight among the examined population is more common by boys (17.7%) than by girls (12.8%). Obesity was observed among 4.7% of boys and 4.4% of girls. In the group of children and youth with overweight 42.2% boys and 67.2% girls correctly describes to actual weight and height proportions. Among the children and young people classified as overweight 88.9% boys and 75% girls perceived themselves as "too fat". Among the respondents with overweight and obesity 67.9% boys and 85.9% have declared trying to lose weight. The most popular methods used to regulating body weight are physical exercises and low-calories diet. Girls in comparing to boys they more often declare for lowering the body weight. The most popular method used to accomplish this aim is physical activity. One should explain to pupils of the appropriate body mass for the health and acquaint objective methods of estimation of the weight and height proportions and safe methods of their regulation.

    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.

    What advice should I give parents of overweight children about physical activity? How can we encourage these children to become more physically active? The Canadian Paediatrics Society 2002 position statement on healthy living for children and youth, which is currently being revised, recommends that physicians advise children and adolescents to increase the time they spend on physical activities by at least 30 minutes a day, with at least 10 minutes involving vigorous activities, and that goals should be reset to reach at least 90 minutes a day of total physical activity. The extent to which children and youth are physically active is influenced by a multitude of complex, interrelated factors. Addressing physical inactivity and its contribution to childhood obesity requires a comprehensive and holistic approach.

    Research indentifies that a significant proportion of youth within the justice system possess some form of mental health disorder, and that the presence of an emotional disorder can provide important explanatory value regarding the causes of crime. Evidence is now overwhelming that services within the youth justice system need to account for the causes of crime in order to effectively reduce the likelihood of reoffending. Such an ethic within youth justice service delivery not only reduces symptoms and risk within the youth and their families but also is linked to increasing community safety through reductions in reoffending. This review characterizes the relevance of mental health disorder in considering the needs of anti-social youth, and how this appreciation is linked to the delivery of effective services as well as what constitutes supportive youth justice legislation.

    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

Youth violence prevention work at the Division of Violence Prevention (DVP) at the Centers for Disease Control and Prevention (CDC) emphasizes preventing youth violence-related behaviors, injuries, and deaths by collaborating with academic and community partners and stakeholders. In 2000 and 2005, DVP funded the National Academic Centers of Excellence (ACE) for Youth Violence Prevention. Most ACE Centers focus on building community capacity and competence so that evidence-based programs for youth violence prevention can be successfully implemented through effective and supportive research-community partnerships. This commentary provides historical information about the ACE Program, including the development, goals, accomplishments of the Centers, and the utilization of a community-based participatory research approach to prevent youth violence.

    In early 2000, the American Legacy Foundation launched the national "truth" campaign, the first national antismoking campaign to discourage tobacco use among youths. We studied the impact of the campaign on national smoking rates among US youths (students in grades 8, 10, and 12). We used data from the Monitoring the Future survey in a pre/post quasi-experimental design to relate trends in youth smoking prevalence to varied doses of the "truth" campaign in a national sample of approximately 50000 students in grades 8, 10, and 12, surveyed each spring from 1997 through 2002. Findings indicate that the campaign accounted for a significant portion of the recent decline in youth smoking prevalence. We found that smoking prevalence among all students declined from 25.3% to 18.0% between 1999 and 2002 and that the campaign accounted for approximately 22% of this decline. This study showed that the campaign was associated with substantial declines in youth smoking and has accelerated recent declines in youth smoking prevalence.

    Obesity is a significant and increasing public health concern in the United States and worldwide. Clinical and epidemiological evidence clearly shows that genetic and environmental factors contribute to the increased susceptibility of humans to obesity and its associated comorbidities; the interplay of these factors is explained by the concept of epigenetics. The impact of maternal obesity goes beyond the newborn period; fetal programming during the critical window of pregnancy, can have long term detrimental effects on the offspring as well as future generations. Emerging evidence is uncovering a link between the clinical and molecular findings in the offspring with epigenetic changes in the setting of maternal obesity. Research targeted towards reducing the transgenerational propagation and developmental programming of obesity is vital in reducing the increasing rates of disease.

    Although several genomewide scans have identified quantitative-trait loci influencing several obesity-related traits in humans, genes influencing normal variation in obesity phenotypes have not yet been identified. We therefore performed a genome scan of body mass index (BMI) on Mexican Americans, a population prone to obesity and diabetes, using a variance-components linkage analysis to identify loci that influence BMI. We used phenotypic data from 430 individuals (26% diabetics, 59% females, mean age +/- SD = 43 +/- 17 years, mean BMI +/- SD = 30.0 +/- 6.7, mean leptin (ng/ml) +/- SD = 22.1 +/- 17.1) distributed across 27 low-income Mexican American pedigrees who participated in the San Antonio Family Diabetes Study (SAFDS) for whom a 10-15-cM map is available. In this genomewide search, after accounting for the covariate effects of age, sex, diabetes, and leptin, we identified a genetic region exhibiting the most highly significant evidence for linkage (LOD 4.5) with BMI on chromosome 4p (4p15.1) at 42 cM, near marker D4S2912. This linkage result has been confirmed in an independent linkage study of severe obesity in Utah pedigrees. Two strong positional candidates, the human peroxisome proliferator-activated receptor gamma coactivator 1 (PPARGC1) and cholecystokinin A receptor (CCKAR) with major roles in the development of obesity, are located in this region. In conclusion, we identified a major genetic locus influencing BMI on chromosome 4p in Mexican Americans.

    Lopomo, A; Burgio, E; Migliore, L

    2016-01-01

    Obesity is a metabolic disease, which is becoming an epidemic health problem: it has been recently defined in terms of Global Pandemic. Over the years, the approaches through family, twins and adoption studies led to the identification of some causal genes in monogenic forms of obesity but the origins of the pandemic of obesity cannot be considered essentially due to genetic factors, because human genome is not likely to change in just a few years. Epigenetic studies have offered in recent years valuable tools for the understanding of the worldwide spread of the pandemic of obesity. The involvement of epigenetic modifications-DNA methylation, histone tails, and miRNAs modifications-in the development of obesity is more and more evident. In the epigenetic literature, there are evidences that the entire embryo-fetal and perinatal period of development plays a key role in the programming of all human organs and tissues. Therefore, the molecular mechanisms involved in the epigenetic programming require a new and general pathogenic paradigm, the Developmental Origins of Health and Disease theory, to explain the current epidemiological transition, that is, the worldwide increase of chronic, degenerative, and inflammatory diseases such as obesity, diabetes, cardiovascular diseases, neurodegenerative diseases, and cancer. Obesity and its related complications are more and more associated with environmental pollutants (obesogens), gut microbiota modifications and unbalanced food intake, which can induce, through epigenetic mechanisms, weight gain, and altered metabolic consequences.

    Restorative sleep is clearly linked with well-being in youth with chronic health conditions. This review addresses the methodological quality of non-pharmacological sleep intervention (NPSI) research for youth with chronic health conditions. The Guidelines for Critical Review (GCR) and the Effective Public Health Practice Project Quality Assessment Tool (EPHPP) were used in the review. The search yielded 31 behavioural and 10 non-behavioural NPSI for review. Most studies had less than 10 participants. Autism spectrum disorders, attention deficit/hyperactivity disorders, down syndrome, intellectual disabilities, and visual impairments were the conditions that most studies focused upon. The global EPHPP scores indicated most reviewed studies were of weak quality. Only 7 studies were rated as moderate, none were strong. Studies rated as weak quality frequently had recruitment issues; non-blinded participants/parents and/or researchers; and used outcome measures without sound psychometric properties. Little conclusive evidence exists for NPSIs in this population. However, NPSIs are widely used and these preliminary studies demonstrate promising outcomes. There have not been any published reports of negative outcomes that would preclude application of the different NPSIs on a case-by-case basis guided by clinical judgement. These findings support the need for more rigorous, applied research. • Methodological Quality of Sleep Research • Disordered sleep (DS) in youth with chronic health conditions is pervasive and is important to rehabilitation therapists because DS contributes to significant functional problems across psychological, physical and emotional domains. • Rehabilitation therapists and other healthcare providers receive little education about disordered sleep and are largely unaware of the range of assessment and non-pharmacological intervention strategies that exist.

    Mentally ill youth are at risk for developing obesity, especially when they require antipsychotic treatment; moreover, they may face unique challenges in adhering to behavioral weight loss interventions. The aims of this project were to characterize the challenges families of youth with psychiatric disorders face when engaging in weight loss treatment and to gather information on attitudes and preferences for weight management interventions in this population. We devised a telephone survey to evaluate caregiver-perceived barriers/challenges to and preferences for behavioral weight loss treatment in overweight or obese mentally ill youth ages 6-18 treated with an antipsychotic agent in an outpatient setting. A total of 26 parents or primary caregivers completed the survey. The most commonly cited barriers to participation in physical activity (PA) and maintaining a healthy diet were child's dislike of PA and child's preference for energy-dense foods, respectively, which were impacted by psychiatric symptoms. Preferences for weight loss treatment included individualized, prescribed meal plans and shopping lists, and exercise support/demonstration, with a preference for Internet or cell phone applications to help with monitoring food intake and exercise. These results suggest that targets for obesity treatment in this population include individualized, specific support that takes into account the child's motivation, which is effected by psychiatric symptoms. Tools for providing support may include the use of telehealth visits and mobile device applications for self-monitoring.

    To ascertain whether pediatric obesity without clinically significant insulin resistance (IR) impacts brain structure and function. Thirty obese and 30 matched lean adolescents, all without clinically significant IR or a diagnosis of metabolic syndrome (MetS), received comprehensive endocrine, neuropsychological, and MRI evaluations. Relative to lean adolescents, obese non-IR adolescents had significantly lower academic achievement (i.e., arithmetic and spelling) and tended to score lower on working memory, attention, psychomotor efficiency, and mental flexibility. In line with our prior work on adolescent MetS, memory was unaffected in uncomplicated obesity. Reductions in the thickness of the orbitofrontal and anterior cingulate cortices as well as reductions of microstructural integrity in major white matter tracts without gross volume changes were also uncovered. It was documented, for the first time, that adolescents with uncomplicated obesity already have subtle brain alterations and lower performance in selective cognitive domains. When interpreting these preliminary data in the context of our prior reports of similar, but more extensive brain findings in obese adolescents with MetS and T2DM, it was concluded that "uncomplicated" obesity may also result in subtle brain alterations, suggesting a possible dose effect with more severe metabolic dysregulation giving rise to greater abnormalities.

    Mexican American youth (N = 146; age range: 14-19 years) living in an immigrant enclave who resided with both parents reported depression symptoms, paternal and maternal acceptance, paternal and maternal harsh parenting, and economic stress. Despite lower levels of youth-reported paternal parenting relative to maternal parenting, paternal acceptance was significantly related to youth depression symptoms in a path model that accounted for parenting intercorrelations as well as other significant correlates of youth depression symptoms. We found evidence suggesting that the relation between youth-reported paternal acceptance and depression might be stronger for girls than for boys. Using an ecological analytic framework, we found that: (a) the link between economic stress and youth depression was robust, and (b) only one parenting variable (paternal acceptance) may partially mediate the link between economic stress and depression symptoms. Our results suggest that paternal parenting and youth gender deserve further consideration in longitudinal research and intervention research addressing depression among Latino youth. Ecological models that highlight the influence of settings where Latino youth and families live should be considered in research on the family relationship context of youth depression.
