    The high prevalence of obesity in the pediatric age groups draws attention to lifestyle factors including diet and physical activity. Data on obesity in adolescents and their snacking behavior are conflicting. This study aimed to assess the association of snacking behavior and obesity among female adolescents in Isfahan, Iran. This cross-sectional study was carried out on 265 female Isfahanian students who were chosen by systematic cluster random sampling. Dietary intake was assessed using a validated self-administered semiquantitative food frequency questionnaire that included 53 food items. Snacking behavior was defined by healthy snack score in combination with the frequency of snack intake. Individuals who consumed more healthy snacks and those with snacking frequency of 4 times a day or more had significantly lower weight, body mass index (BMI), and waist circumference (p associated with a greater chance of being overweight, generally obese, and abdominally obese among adolescents (odds ratio [OR] = 1.98; 95% confidence interval [CI], 1.00-3.14, ptrend = 0.04 and OR = 2.10; 95% CI, 1.01-3.13, ptrend = 0.04, respectively). Frequency of snack intake was inversely related to overweight, general obesity, and abdominal obesity (OR = 3.23; 95% CI, 1.73-5.61, ptrend = 0.03 and OR = 1.84; 95% CI, 1.05-3.20, ptrend = 0.04, respectively). Healthy snack score in combination with frequency of snacking showed that those in the lowest tertile of snacking who consumed snacks less than 4 times/day had the highest risk of obesity compared to other categories (OR = 2.09, 95% CI, 1.11-3.20, p associated with decreased prevalence of overweight, general obesity, and abdominal obesity in adolescents. Further studies, in particular of a prospective nature, are required to examine this association in other populations.

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

    Full Text Available Introduction: Nutritional obesity is the most common cause of obesity (95% in childhood and adolescence. Morbid obesity (5%, which usually begins at an early age, can be caused by monogenic disorders, various genetic syndromes, endocrine diseases-disorders, central nervous system lesions or iatrogenic causes. Presentation of the patient: A female adolescent aged 13 is presented who was due to obesity referred to the Center for the Prevention and Treatment of Obesity in children and adolescents at the Special Hospital “Cigota” at Mt. Zlatibor. Low height/stature and dysmorphic features: a face with a narrow bifrontal diameter, almond-shaped eyes, strabismus, small hands and feet, delay in puberty development and lagging in psychomotor development have indicated the morbid obesity. Anamnestic data on hypotonia and difficulty in feeding, psychomotor lagging behind, obesity since the third year of age, triggered a suspicion of Prader Willy’s syndrome. The suspicion of this syndrome was confirmed by a molecular DNA analysis which indicated a deletion on the long arm 15q11.2. Conclusion: Obesity, endocrinolopathies, retardation in psychomotor development and behavioral disorders in people with Prader Willy’s syndrome require a complex multidisciplinary treatment. Early diagnosis and adequate treatment prevent the occurrence of complications and improve the quality and length of life of the patients.

    Full Text Available Objective: the study identifies the presence of the signs of depression, teasing and self-esteem in obese female adolescents compared to a control group. Methods: the studied group consisted of female subjects (N= 106 obese adolescents and 106 control group aged from 12 to 18. In the study, the subjects were administered measures of body image, Montgomery Asberg depression rating scale (MADRS, Scale of perceived Teasing, Self-Liking (SL and Self-competence (SC to appraise self-esteem. Results: the comparative assessment highlighted that obese adolescents are significantly depressed. Regarding the teasing, the adolescents were affected from a physical viewpoint. A significant difference also emerged in relation to self-esteem. Conclusion: the emotional consequences should be carefully weighed  in consideration of the possible psychopathologies that may arise, i.e. mood signs. In relation to the signs, the prevention  with psychological interventions is important for eating disorders and  improve psychosocial health.

    Objective Severe obesity is the fastest growing pediatric subgroup of excess weight levels. Psychological dysregulation (i.e., impairments in regulating cognitive, emotional, and/or behavioral processes) has been associated with obesity and poorer weight loss outcomes. The present study explored associations of dysregulation with weight-related variables among adolescent and young adult (AYA) females with severe obesity. Methods Fifty-four AYA females with severe obesity (MBMI=48.71 kg/m2; Mage=18.29, R=15–21 years; 59.3% White) completed self-report measures of psychological dysregulation and weight-related constructs including meal patterns, problematic eating behaviors, and body and weight dissatisfaction, as non-surgical comparison participants in a multi-site study of adolescent bariatric surgery outcomes. Pearson and bivariate correlations were conducted and stratified by age group to analyze associations between dysregulation subscales (affective, behavioral, cognitive) and weight-related variables. Results Breakfast was the most frequently skipped meal (consumed 3–4 times/week). Eating out was common (4–5 times/week) and mostly occurred at fast-food restaurants. Evening hyperphagia (61.11%) and eating in the absence of hunger (37.04%) were commonly endorsed, while unplanned eating (29.63%), a sense of loss of control over eating (22.22%), eating beyond satiety (22.22%), night eating (12.96%), and binge eating (11.11%) were less common. Almost half of the sample endorsed extreme weight dissatisfaction. Dysregulation was associated with most weight-related attitudes and behaviors of interest in young adults but select patterns emerged for adolescents. Conclusions Higher levels of psychological dysregulation are associated with greater BMI, problematic eating patterns and behaviors, and body dissatisfaction in AYA females with severe obesity. These findings have implications for developing novel intervention strategies for severe obesity in AYAs that may

    RTI International is acknowledged for supporting the time of Susan McRitchie, Keeley Pratt and Susan Sumner to participate in the design, execution, or analysis of this study. East Carolina University would like to acknowledge Brittney France for being a triangulated investigator for the qualitative analysis and to the Pitt Memorial Hospital Foundation for financial support of the healthy lifestyles camp. Our purpose was to evaluate the views of obese African-American (AA) female adolescents concerning parent and family factors relating to obesity and a healthy lifestyle. Obese AA female adolescents enrolled in a residential healthy lifestyle program completed inventories measuring family functioning and perceptions of parenting styles, and participated in focus groups to identify themes regarding parent and family involvement in healthy lifestyle change. The majority of participants' mothers were scored as "inductive/authoritative" and fathers were "indulgent". Mothers reportedly were seen as more likely to encourage dieting to control weight than fathers. Common themes of the focus groups included a desire for family involvement, identification of family behaviors that were supportive as well as those which were perceived as unhelpful. Though generalizability of these results is limited by a homogenous small sample size, our results suggest that obese adolescents seeking weight loss treatment desire significant family involvement in their efforts. © 2015 National Medical Association.

    To determine the prevalence of pain, musculoskeletal syndromes, orthopedic disorders and using computers and playing videogames among obese adolescents. This was a cross-sectional study that investigated 100 consecutive obese adolescents and 100 healthy-weight controls using a confidential, self-report questionnaire covering demographic data, sports participation, painful musculoskeletal system symptoms and using computers and playing videogames. The questionnaire's test-retest reliability was tested. Physical examination covered six musculoskeletal syndromes and seven orthopedic disorders. The kappa index for test-retest was 0.724. Pain and musculoskeletal syndromes were equally prevalent in both groups (44 vs. 56%, p = 0.09; 12 vs. 16%, p = 0.541; respectively). Notwithstanding, orthopedic disorders (98 vs. 76%, p = 0.0001), tight quadriceps (89 vs. 44%, p = 0.0001) and genu valgum (87 vs. 24%, p = 0.0001) were significantly more prevalent in obese adolescents than in controls. Median time spent using a computer the day before, on Saturdays and on Sundays were all lower among the obese subjects (30 vs. 60 minutes, p = 0.0001; 1 vs. 60 minutes, p = 0.001; and 0 vs. 30 minutes, p = 0.02; respectively). Obese adolescents were less likely to play handheld videogames (2 vs. 11%, p = 0.003) and there was no difference in the two groups' use of full-sized videogames (p > 0.05). Comparing obese adolescents with pain to those free from pain revealed that pain was more frequent among females (59 vs. 39%, p = 0.048) and was associated with greater median time spent playing on Sundays [0 (0-720) vs. 0 (0-240) minutes, p = 0.028]. Obesity can cause osteoarticular system damage at the start of adolescence, particularly to the lower limbs. Programs developed specifically for obese female adolescents with musculoskeletal pain are needed.

    The increased prevalence of adolescent obesity and associated short-term and long-term complications emphasize the need for effective treatment. In this Review, we aim to describe the evidence for, and elements of, behaviour management and adjunctive therapies and highlight the opportunities and challenges presented by obesity management in adolescence. The broad principles of treatment include management of obesity-associated complications; a developmentally appropriate approach; long-term behaviour modification (dietary change, increased physical activity, decreased sedentary behaviours and improved sleep patterns); long-term weight maintenance strategies; and consideration of the use of pharmacotherapy, more intensive dietary therapies and bariatric surgery. Bariatric surgery should be considered in those with severe obesity and be undertaken by skilled bariatric surgeons affiliated with teams experienced in the medical and psychosocial management of adolescents. Adolescent obesity management strategies are more reliant on active participation than those for childhood obesity and should recognize the emerging autonomy of the patient. The challenges in adolescent obesity relate primarily to the often competing demands of developing autonomy and not yet having attained neurocognitive maturity.

    While pediatric anti-obesity lifestyle interventions have received considerable attention, few show sustained impact on body mass index (BMI). Using the Information-Motivation-Behavioral Skills Theory as a framework, we examined the effects of a satiety-focused mindful eating intervention (MEI) on BMI, weight and mindful awareness. Utilizing a two-group, repeated measures design, 37 adolescent females with a BMI >90th percentile, recruited from a public high school in a Latino community in the Southwestern United States, were randomized 2:1, one third to the group receiving a 6-week MEI and two thirds to the comparison group (CG) receiving the usual care (nutrition and exercise information). During six weekly 90-min after school MEI group sessions, the behavioral skills of slow intentional eating were practiced with foci on satiety cues and triggers to overeat. Feasibility and acceptability were measured as participant retention (goal ≥55%) and evaluative comments from those in the MEI group, respectively. BMI and mindful awareness were measured on site at baseline, immediately post intervention, and at 4-week follow-up (week 10). Fifty-seven and 65% of those in the MEI and CG were retained throughout the study, respectively. MEI participants showed significantly lowered BMI compared with CG participants, whose weight increased (p90th percentile standard growth projections). Initial and sustained decline of BMI in the MEI group supports further study of this theory-guided approach, and the value of practicing satiety-focused mindful eating behavioral skills to facilitate health behavior change.

    The prevalence of obesity has continued to rise at an alarming rate worldwide to such an extent that it has been described as a global epidemic. Our study aims to investigate the pattern and determinants of obesity among adolescent females in private and public schools in the Olorunda Local Government Area of Osun State, Nigeria. This is a cross-sectional descriptive study. Using the multistage sampling technique, 520 pre-tested, semi-structured questionnaires were administered to 257 girls from private schools and 263 girls from public schools. Most of the respondents from private schools (65.2%) had good knowledge about obesity and related matters while most of those from public schools (65.9%) had poor knowledge. The dietary practice of the majority of the girls from private schools (60.2%) was unhealthy while most of the girls from public schools (68.7%) had healthy dietary practices. Most of the respondents from private schools (64.2%) lived sedentary lifestyles while most from public schools (64.0%) lived active lifestyles. Using the BMI, the majority of the girls from private schools were underweight (52%), 10 (4.0%) were overweight and 3 (1.2%) were obese. For public schools, the majority (55.4%) fell within the normal group, 6 (2.3%) were overweight and none was obese. The prevalence of being overweight and of obesity was higher among the girls in private schools than among girls attending public schools. We concluded that awareness should be created to promote a healthy balance of food, drink and physical activity within and outside the school.

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

    Obesity and major depressive disorder (MDD) are associated, but evidence about how they relate over time is conflicting. The goal of this study was to examine prospective associations between depression and obesity from early adolescence through early adulthood. Participants were drawn from a statewide, community-based, Minnesota sample. MDD and obesity with onsets by early adolescence (by age 14), late adolescence (between 14 and 20) and early adulthood (ages 20-24) were assessed via structured interview (depression) and study-measured height and weight. Cross-sectional results indicated that depression and obesity with onsets by early adolescence were concurrently associated, but the same was not true later in development. Prospective results indicated that depression by early adolescence predicted the onset of obesity (odds ratio (OR)=3.76, confidence interval =1.33-10.59) during late adolescence among female individuals. Obesity that developed during late adolescence predicted the onset of depression (OR=5.89, confidence interval=2.31-15.01) during early adulthood among female individuals. For girls, adolescence is a high-risk period for the development of this comorbidity, with the nature of the risk varying over the course of adolescence. Early adolescent-onset depression is associated with elevated risk of later onset obesity, and obesity, particularly in late adolescence, is associated with increased odds of later depression. Further investigation into the mechanisms of these effects and the reasons for the observed gender and developmental differences is needed. Prevention programs focused on early-onset cases of depression and adolescent-onset cases of obesity, particularly among female individuals, may help in reducing risk for this form of comorbidity.

The HIIT and MIIT groups showed improved (p HIIT group showed decreased waist circumference (WC) (p = 0.017). The effect of exercise on maximal oxygen uptake (VO2max) was significant (p = 0.019, ES = 0.48 and p = 0.010, ES = 0.57, HIIT and MIIT, respectively). The decrease of rate-pressure product (RPP) (p HIIT and MIIT, respectively) followed the positive changes in resting heart rate and blood pressures. Blood glucose, insulin level and the homeostasis model assessment index for insulin decreased (p HIIT and MIIT, respectively. In the post-intervention period, blood leptin was strongly associated with %BF (p HIIT and MIIT groups, respectively, while RPE was strongly associated with BM (p HIIT group. The results suggest that high-intensity interval training may produce more positive effects on health determinants in comparison with the same training mode at a moderate intensity.

    Full Text Available Abstract 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.

    Conclusions: These findings suggest that adolescent obesity is linked to disrupted functional connectivity in brain networks relevant to maintaining balance between reward, emotional memories and cognitive control. Our findings may contribute to reconceptualization of obesity as a multi-layered brain disorder leading to compromised motivation and control, and provide a biological account to target prevention strategies for adolescent obesity.

    ABSTRACT The nutrition transition with associated lifestyle-related non-communicable diseases has rapidly reached many developing countries, including Saudi Arabia. Therefore, the objective of this study was to examine the prevalence of overweight, obesity, and abdominal obesity among Saudi adolescents. This school-based multicentre cross-sectional study was conducted during 2009-2010 in three major cities in Saudi Arabia: Al-Khobar, Jeddah, and Riyadh. Participants included 2,908 students of secondary schools (1,401 males and 1,507 females) aged 14 to 19 years, randomly selected using a multistage stratified cluster-sampling technique. Weight, height, and waist-circumference were measured; prevalence of overweight and obesity was determined using age- and sex-specific BMI cutoff reference standards of the International Obesity Task Force (IOTF). Abdominal obesity was determined using waist-to-height ratio (WHtR) cutoffs (above 0.5). The prevalence of overweight was 19.5% in males and 20.8% in females while that of obesity was 24.1% in males and 14% in females. The prevalence of abdominal obesity in males and females was 35.9% and 30.3% respectively. Higher prevalence of obesity was observed among adolescents in private schools. Across all ages, overweight and obesity ranged from 39.9% to 45.6% in males and from 30.4% to 38.7% in females. ANCOVA, controlling for age, showed significant interaction effects (city by gender). It is concluded that the proportions of overweight, obesity, and abdominal obesity, observed among Saudi adolescents were remarkably high. Such high prevalence of overweight and obesity is a major public-health concern. PMID:25895197

    Consumer health technologies (CHTs) are a growing part of the continuum of care for self-management of overweight and obesity. Parents positively or negatively influence adolescent weight-management efforts and are especially important throughout continuum of care settings. User-centered design (UCD) applications have been developed to assist primary users, such as adolescents, with their weight management, but less is known about the influence of parents as secondary users across many socio-ecological environments. The purpose of this study was to use the Unified Theory of Acceptance and Use of Technology (UTAUT) to inform the design of a UCD application in a qualitative study that sought to determine parental views on how technology can support previously learned behaviors that require ongoing management and support beyond formal lifestyle interventions. Parents of overweight and obese adolescents (n=14) were interviewed about perceived usefulness and planned user-intent of CHT that was designed for adolescents. UTAUT provided theoretical parental constructs (intention, performance and effort expectancy, and social influence) interactions within several socio-ecological contexts, including the home food environment and restaurant dining experiences. Although generalizations of this qualitative study are limited by a small sample size with predominantly mothers (n=13) of overweight and obese daughters (n=12), the exploratory inquiry using a parent as a secondary consumer user can complement the adoption of applications designed by adolescents.

    This article describes the life conditions of female adolescents in India and issues such as health, discrimination in nutrition and literacy, child labor, early marriage, juvenile delinquency, and violence against girls in rural areas of India. Data are obtained from interview samples conducted among 12 villages in north India. Female adolescents suffer from a variety of poverty-ridden village life conditions: caste oppression, lack of facilities, malnutrition, educational backwardness, early marriage, domestic burden, and gender neglect. Girls carry a heavy work burden. Adolescence in rural areas is marked by the onset of puberty and the thrust into adulthood. Girls have no independent authority to control their sexuality or reproduction. Girls are expected to get married and produce children. Control of female sexuality is shifted from the father to the husband. There is a strong push to marry girls soon after menstruation, due to the burden of imposing strict restrictions on female sexuality, the desire to reduce the burden of financial support, and the need to ensure social security for daughters. Girls may not go out alone or stay outside after dark. Many rural parents fear that education and freedom would ruin their daughter. Girls develop a low self-image. Rural villages have poor sanitation, toilet facilities, and drainage systems. Girls are ignorant of health and sex education and lack access to education. The neglect of female children includes malnutrition, sex bias, and early marriage. In 1981, almost 4 out of every 100 girls had to work. 5.527 million girls 5-14 years old were child laborers. Girls are veiled, footbound, circumcised, and burnt by dowry hungry in-laws. Female delinquents are subjected to sexual harassment and sometime to sexual abuse while in custody. Cows are treated better in rural India than women. Gender disparity is caused by the perpetuation of patriarchal masculine values.

    The role of gastrointestinal peptides in eating disorders has yet to be determined. Methods: In this study we examined plasma levels of gastrin (G), cholecystokinin (CCK), and pancreatic polypeptide (PP) in adolescent anorexic, and obese female subjects hospitalized for feeding behavior disorders. Six anorexic, six obese and six control young females (ages 13-26) were studied after an overnight fast and after consuming a liquid test meal. The liquid test meal (Ensure, Ross Laboratories; Columbus OH) consisted of 14% calories as protein, 31.5% calories as fat and 54.5% calories as carbohydrate in a 240ml volume. Plasma levels of gastrointestinal peptides, G, CCK and PP were determined by specific radioimmunoassay. The data were analyzed by one way analysis of variance and the Student's t-test. Results: show that fasting levels of G were greater in control and obese groups than the anorexic subjects. Postprandial G levels for controls were higher than the anorexic, and obese groups respectively. When fasting and postprandial G levels were compared among the same groups only the controls increased after eating. Fasting CCK levels were lower in control and anorexic groups than the obese group. Postprandial CCK levels were higher among control patients compared to anorexic and obese subjects. When fasting and postprandial CCK levels were compared among groups, only control levels increased after eating. Fasting and postprandial PP levels were not different between groups. Postprandial PP levels increased over fasting PP levels only in controls

    Full Text Available This study examined the effects of high- vs. moderate-intensity interval training on cardiovascular fitness, leptin levels and ratings of perceived exertion (RPE in obese female adolescents. Forty-seven participants were randomly assigned to one of three groups receiving either a 1:1 ratio of 15 s of effort comprising moderate-intensity interval training (MIIT at 80% maximal aerobic speed: MAS or high-intensity interval training (HIIT at 100% MAS, with matched 15 s recovery at 50% MAS, thrice weekly, or a no-training control group. The HIIT and MIIT groups showed improved (p˂0.05 body mass (BM, BMI Z-score, and percentage of body fat (%BF. Only the HIIT group showed decreased waist circumference (WC (p=0.017. The effect of exercise on maximal oxygen uptake (VO2max was significant (p=0.019, ES=0.48 and p=0.010, ES=0.57, HIIT and MIIT, respectively. The decrease of rate-pressure product (RPP (p<0.05, ES=0.53 and ES=0.46, HIIT and MIIT, respectively followed the positive changes in resting heart rate and blood pressures. Blood glucose, insulin level and the homeostasis model assessment index for insulin decreased (p<0.05 in both training groups. Significant decreases occurred in blood leptin (p=0.021, ES=0.67 and p=0.011, ES=0.73 and in RPE (p=0.001, ES=0.76 and p=0.017, ES=0.57 in HIIT and MIIT, respectively. In the post-intervention period, blood leptin was strongly associated with %BF (p<0.001 and VO2max (p<0.01 in the HIIT and MIIT groups, respectively, while RPE was strongly associated with BM (p<0.01 in the HIIT group. The results suggest that high-intensity interval training may produce more positive effects on health determinants in comparison with the same training mode at a moderate intensity.

    We studied the effect of metformin or placebo in a lifestyle modification program (LSM) combined with oral contraceptives (OC) on quality of life parameters measured by the PCOS questionnaire (PCOSQ) in obese adolescent women with validated PCOS. The quality of life indicators were measured at baseline and conclusion for 5 domains on the PCOSQ, with equal improvement in scores in both placebo and Metformin groups, suggesting metformin addition does not add improvement to quality of life measures above those observed with lifestyle modification and oral contraceptive treatment.

    The worldwide upward trend in obesity has been dramatic, now affecting more than 20% of American women of reproductive age. Obesity is associated with many adverse maternal and fetal effects prenatally, but it also exerts a negative influence on female fertility. Obese women are more likely to have ovulatory dysfunction due to dysregulation of the hypothalamic-pituitary-ovarian axis. Women with polycystic ovarian syndrome who are also obese demonstrate a more severe metabolic and reproductive phenotype. Obese women have reduced fecundity even when eumenorrheic and demonstrate poorer outcomes with the use of in vitro fertilization. Obesity appears to affect the oocyte and the preimplantation embryo, with disrupted meiotic spindle formation and mitochondrial dynamics. Excess free fatty acids may have a toxic effect in reproductive tissues, leading to cellular damage and a chronic low-grade inflammatory state. Altered levels of adipokines, such as leptin, in the obese state can affect steroidogenesis and directly affect the developing embryo. The endometrium is also susceptible, with evidence of impaired stromal decidualization in obese women. This may explain subfecundity due to impaired receptivity, and may lead to placental abnormalities as manifested by higher rates of miscarriage, stillbirth, and preeclampsia in the obese population. Many interventions have been explored to mitigate the effect of obesity on infertility, including weight loss, physical activity, dietary factors, and bariatric surgery. These data are largely mixed, with few high quality studies to guide us. As we improve our understanding of the pathophysiology of obesity in human reproduction we hope to identify novel treatment strategies. Copyright © 2017 American Society for Reproductive Medicine.

    Full Text Available Background: The behavior and dietary treatments are not so successful for extremely obese adolescents. Therefore, using drugs to treat extremely obese children and adolescents are among the modern approaches. This research aims to study the pharmaceutical interventions performed for treatment of obese children. Materials and Methods: The strategy of research was using of key words ‘obesity’, ‘adolescence’, ‘treatment’ and ‘anti-obesity drugs’ were searched in websites of PubMed, Iranian Medical Digital Library, SID, Iran Medex, Magiran. This study reviewed all the available published papers in English and Farsi languages during 2000-2010. The Criteria for exclusion was The papers that had been published on interventions and treatment of eating disorders, type II diabetes or the obesity caused by the secondary syndromes. Results: Twelve papers were found as short-term clinical trials and/or long-term follow-ups. In these studies, the positive effects of ‘sibutramine’ in some studies are shown; although some other side effects are reported as well. A significant weight-loss had been reported on ‘orlistat’ medicine, but digestive complications had been observed as well. None of the studies had followed up patients for more than one year. Apparently, ‘Metformin’ requires further studies.Conclusion: The FDA has only approved ‘sibutramine’ and ‘orlistat’ drugs. But side effects of long-term these drugs have already been unknown. However, it seems that ‘orlistat’ is applied for ≥12-year-old children and ‘sibutramine’ for ≥ 16-year-old children.

    Firstly, essential developmental aspects of the focused periods of life, namely childhood and adolescence, are discussed. Furthermore, different issues of overweight and obesity in childhood and adolescence are highlighted. Besides the definition and the assessment, possibilities of classification and epidemiological aspects are of interest. Physical and psychiatric consequences, which can be associated with obesity are also presented. In the context of a model of multifactorial genesis of obesity, different causing and maintaining factors are described. In addition to genetic and biological risk factors, the significance of several psychosocial factors is illustrated. Finally, the focus is on the therapy of obesity in childhood and adolescence.

    Obesity and overweight are a pandemic phenomenon in the modern world. Childhood and adolescent obesity often ends up in obesity in adults. The costs of obesity and its consequences are staggering for any society, crippling for countries in development. The etiology is complex, but most often idiopathic. Hormonal, syndromic and medication-induced obesity are well investigated. Genetic causes are increasingly described. Novel technologies such as whole exome sequencing identify ever more candidate genes influencing or causing obesity. All insights into the complex problem of obesity in a team approach to treatment: diet, psychology, medications and surgery. We briefly review epidemiology, etiology, consequences and treatment approaches in childhood and adolescent obesity, with special emphasis on emerging knowledge of its genetics.

    The current impact of adolescent obesity on educational attainment is not clear. The objectives of our study were to determine whether adolescent obesity is associated with college degree attainment and how this association may have changed over time. We used data from a contemporary national cohort of over 4,000 persons who were adolescents (aged 14-18) in 1997 to assess the relationship between adolescent obesity and education. To assess for changes in this relationship over time, we also analyzed an older, similarly structured cohort of over 3,000 persons who were adolescents (aged 16-18) in 1981. Our primary outcome was college degree completion. We found that in the older cohort (adolescents in 1979), there were no differences in college degree attainment by adolescent weight status before and after adjustment. However, unadjusted analysis of the contemporary cohort (adolescents in 1997) demonstrated that those who were normal weight as adolescents had a higher prevalence of college degree attainment at follow-up compared to obese adolescents (24% vs. 10%). After adjustment for socio-demographic variables (age, sex, race, height, parental income-to-poverty ratio, parental education, aptitude test scores), obese adolescents were less likely to have attained a college degree compared to normal weight peers (adjusted risk ratio 0.61 95% confidence interval 0.38-0.83). Expectations for a future college degree did not vary by weight status and did not explain this observation. In conclusion, adolescent obesity is associated with lower likelihood of college completion. This relationship was not observed in an older cohort of adolescents.

    Low IQ is associated with high BMI in childhood. There are inconsistent findings on the association between low SES and high BMI. Youth with low IQ have been reported to have poorer health behaviors, such as poor nutrition and less physical activity. Low IQ is significantly associated with obesity for both male and female adolescents, though more strongly for female adolescents. Physical activity has a mediating effect on the association between low IQ and obesity among both male and female adolescents, though more strongly for male adolescents. The association between low IQ and obesity is strongest among adolescents from high SES backgrounds. Previous studies have shown an association between low intelligence quotient (IQ), high body mass index and low socioeconomic status (SES). This study examined the cross-sectional association between IQ and obesity, exploring the roles of gender, SES and physical activity in this association. Subjects were 235,663 male and 169,259 female adolescents assessed by the Israeli military draft board. Low IQ was significantly associated with increased odds of obesity among male (odds ratio [OR] = 1.44, 95% confidence interval [CI] = 1.36-1.52) and female adolescents (OR = 1.61, 95% CI = 1.51-1.73); this association was significantly stronger among female adolescents. Sobel tests indicated that physical activity had a significant mediating effect on this association for male and female adolescents, although more strongly for male adolescents. Dividing the sample according to SES, the association between low IQ and obesity was strongest in the high SES group (male adolescents: OR = 1.26, 95% CI = 1.10-1.43, female adolescents: OR = 1.61, 95% CI = 1.38-1.89), even when controlling for physical activity. The findings suggest that low IQ is associated with increased odds of obesity, particularly in female adolescents and in adolescents with high SES. Physical activity has a mediating effect on this

    Full Text Available Obesity has become a global issue. Previous studies in Bali reveal an increase in the proportionof obesity in adolescents. Obesity causes hypertension; hence there should also be an increase inthe prevalence of hypertension as well in Bali. Hypertension in obese adolescents could be causedby various factors, hence identification of the risks factors is crucial as a preventive approach.The aim of this study was to prove an association between obesity and hypertension in adolescents,and to look for the risk factors. We used an analitical cross sectional design conducted to 12-14years old samples. We took body weight, height, waist circumference, hip circumference, andblood pressure measurements with appropriate devices and asked for information regarding lifestyle and familial history by a questionnare filled in by the samples. The association of obeseadolescents with hypertension and their risk factors was analyzed by Chi-square and multivariatetests. A total of 225 subjects from Santo Yoseph junior high school students, west Denpasar,Bali, met the inclusion criteria. The proportion of obese subjects in this study was 25.7%. Wefound that proportion in familial history of obesity was greater in obese than non-obese subjects(70.7 % vs 41.3%. Logistic regression test revealed that obese subjects with hypertension had abody mass index (BMI > 30 with odds ratio of 7.3 (CI 95% = 1.8 to 28.8 and P = 0.005. Weconcluded that there was an association between obesity and adolescents with hypertension,and BMI > 30 could be a risk factor for obese adolescents with hypertension.

    Severe obesity is increasing in adolescents and is associated with cardiovascular disease, type 2 diabetes mellitus, obstructive sleep apnoea, polycystic ovarian syndrome and a range of musculoskeletal problems. Premature death is the inevitable outcome of persistent severe obesity in adolescents. In adults with severe obesity, medical and lifestyle interventions have been shown to be expensive and less effective in terms of weight loss than has bariatric surgery. The single completed randomised controlled trial in adolescents shows the same outcome. This is supported by meta analyses of bariatric surgery in adolescent subjects. A more aggressive approach to severe obesity, utilising bariatric surgery in selected cases, within the context of a multi-disciplinary team, is required. Copyright © 2014.

    Obesity in adolescence will probably have major implications not only for the affected adolescents but also for society. Those who have obesity during adolescence usually have obesity into adulthood, which causes many medical and psychological issues that can result in premature death. Furthermore, obesity in adolescents is associated with a range of social problems, including difficulties securing an apprenticeship or a job or finding a partner. Adolescents with obesity are also at increased risk of having children with obesity later in life. All these consequences lead to high costs for the health-care system. Although efficient treatment options are available that have been proven in randomized controlled trials, such as lifestyle interventions for adolescents with obesity and bariatric surgery for adolescents with severe obesity, these interventions frequently fail in clinical practice as treatment adherence is low in adolescents and most adolescents with obesity do not seek medical care. Therefore, improving treatment adherence and identifying treatment barriers are necessary.

    Obesity and excess weight are a pandemic phenomenon in the modern world. Childhood and adolescent obesity often ends up in obesity in adults. The costs of obesity and its consequences are staggering for any society, crippling for countries in development. Childhood obesity is also widespread in Macedonia. Metabolic syndrome, dyslipidemia and carbohydrate intolerance are found in significant numbers. Parents and grandparents are often obese. Some of the children are either dysmorphic, or slightly retarded. We have already described patients with Prader-Willi syndrome, Bardet-Biedl syndrome or WAGR syndrome. A genetic screening for mutations in monogenic obesity in children with early, rapid-onset or severe obesity, severe hyperphagia, hypogonadism, intestinal dysfunction, hypopigmentation of hair and skin, postprandial hypoglycaemia, diabetes insipidus, abnormal leptin level and coexistence of lean and obese siblings in the family discovers many genetic forms of obesity. There are about 30 monogenic forms of obesity. In addition, obesity is different in ethnic groups, and the types of monogenic obesity differ. In brief, an increasing number of genes and genetic mechanisms in children continue to be discovered. This sheds new light on the molecular mechanisms of obesity and potentially gives a target for new forms of treatment.

    Full Text Available Background: Obesity is a fast growing problem in the developing countries like India and is now known to be associated with increased health risk. Realizing the fact that the obesity in adolescent age group does not receive the deserved attention in the prevention and control programme, the present study was undertaken on 585 adolescent subjects studying in one college and three schools. Aims and Objectives: 1. To study the prevalence of overweight and obesity in adolescent population. 2. To find the association of body mass index (BMI with important parameters like skin fold thickness, waist circumference and waist to hip ratio. Methods: It was a cross sectional observational study. The study population was school and college going adolescents in the age group of 11-19 years. The estimated sample size for present study is 585 students. The subjects were screened by body mass index, skin fold thickness, waist circumference and waist to hip ratio. Results: The prevalence of overweight and obesity was 19.14% and 4.44% respectively. It was found that there was strong association between the waist circumference with overweight and obesity. Similarly a strong association between waist to hip ratio with overweight and obesity has been found. Also it was found that there was a strong association between skin fold thickness with overweight and obesity. Skin-fold thickness has more sensitivity as compared to waist circumference and waist to hip ratio. Waist to hip ratio has got maximum specificity amongst all but when both sensitivity and specificity criteria are considered together waist circumference stands out. Conclusion: It was found that the prevalence of overweight and obesity was 19.14% and 4.44% respectively. Skin-fold thickness has more sensitivity as compared waist circumference and waist to hip ratio. Waist to hip ratio has got maximum specificity.

    Obesity is an increasingly important worldwide health problem, representing the major risk factor for coronary heart disease. The increase in the prevalence of obesity, particularly among younger age groups, is likely to have long-term implications for cardiovascular disease (CVD) in the years to come, especially at a young age. Obesity plays a central role in the insulin resistance (IR) syndrome and increases the risk of atherosclerotic CVD. The present review will examine the relationships among cardiovascular risk (CVR) factors during the childhood-adolescence-adulthood transition. In fact, the relation between obesity, in particular visceral obesity and CVD, appears to develop at a relatively young age. The foremost physical consequence of obesity is atherosclerotic CVD, and an intriguing example of obesity-related cardiovascular complications affecting young women is the polycystic ovary syndrome (PCOS).

    The increasing prevalence and severity of obesity in children and adolescents has provided greater emphasis on the wide variety of comorbid conditions and complications that can be experienced as a consequence of obesity. These complications can occur both in the short term and in the long term. Some complications, earlier thought to be long-term issues, which would only occur in adulthood, have now been shown to occur in children and adolescents. These findings have raised concerns about the overall health experience of those who develop obesity early in life and have even raised questions about whether the obesity epidemic might shorten the life span of the current generation of children. In this paper, I will examine current knowledge regarding the different organ systems that may be impacted by childhood obesity.

    This paper investigates the relationships between body weight, race, and attractiveness in appearance and personality among adolescents. We study a sample of 5947 (non-Hispanic) white and black girls age 12 to 18 who were interviewed by a group of 338 interviewers. We find that overweight and obese white female adolescents are, respectively, 23% and 40% less likely, on average, to be perceived as physically attractive compared to normal-weight white girls. The physical appearance penalties are significantly smaller for overweight and obese black girls compared to white girls. These findings suggest that being overweight or obese is costly due to its negative impact on inner and outer perceived beauty, providing an explanation for the observed stigmatization of overweight and obesity among women in labor and relationship markets. The smaller beauty penalties for black girls above the normal-weight range suggest that the range of body sizes considered attractive may be wider for black females. Published by Elsevier Ltd.

    Full Text Available Objective. The aim of this study was to find out the prevalence of overweight and obesity among adolescents in seven Arab countries using similar reference standard. Methods. A school-based cross-sectional study was carried out in seven cities in Arab countries, namely, Algeria, Jordan, Kuwait, Libya, Palestine, Syria, and United Arab Emirates. A multistage stratified random sampling technique was used. The total sample included was 4698 adolescents aged from 15 to 18 years (2240 males, 2458 females. The International Obesity Task Force (IOTF reference standard was used to classify the adolescents as nonobese, overweight, and obese. Results. Among males, overweight was highest among Kuwaiti adolescents (25.6%, followed by Jordanian (21.6%, and Syrian (19.7% adolescents. Among females, the highest prevalence of overweight was reported in Libyan adolescents (26.6%, followed by Kuwaiti (20.8%, and Syrian (19.7% adolescents. As for obesity, Kuwaiti adolescents showed the highest prevalence of obesity for both males (34.8% and females (20.6%. Conclusion. There is an urgent need to establish a plan of action to combat obesity in schoolchildren in these countries.

    Profound hypokalemia with paralysis usually poses a diagnostic and therapeutic challenge. We report on a 28-y-old obese Chinese female presenting with sudden onset of flaccid quadriparesis upon awaking in the morning. There is no family history of hyperthyroidism. She experienced body weight loss of 7 kg in 2 months. The most conspicuous blood biochemistry is marked hypokalemia (1.8 mmol/l) and hypophosphatemia (0.5 mmol/l) associated with low urine K(+) and phosphate excretion. Surreptitious laxatives and/or diuretics abuse-related hypokalemic paralysis were tentatively made. However, her relatively normal blood acid-base status and the absence of low urine Na(+) and/or Cl(-) excretion made these diagnoses unlikely. Furthermore, she developed rebound hyperkalemia (5.7 mmol/l) after only 80 mmol K(+) supplementation. Thyroid function test confirmed hyperthyroidism due to Graves' disease. Control of the hyperthyroidism completely abolished her periodic paralysis. Thyrotoxic periodic paralysis (TPP) should be kept in mind as a cause of paralysis in female, even with obesity, despite its predominance in adult males. Copyright © 2012 Elsevier B.V.

    The rise in adolescent obesity has become a public health concern, especially because of its impact on disadvantaged youth. This article examines the role of disadvantage at the family-, peer-, school-, and neighborhood-level, to determine which contexts are related to obesity in adolescence and young adulthood. We analyzed longitudinal data from Waves I (1994-1995), II (1996), and III (2001-2002) of the National Longitudinal Study of Adolescent Health, a nationally representative population-based sample of adolescents in grades 7-12 in 1995 who were followed into young adulthood. We assessed the relationship between obesity in adolescence and young adulthood, and disadvantage (measured by low parent education in adolescence) at the family-, peer-, school-, and neighborhood-level using multilevel logistic regression. When all levels of disadvantage were modeled simultaneously, school-level disadvantage was significantly associated with obesity in adolescence for males and females and family-level disadvantage was significantly associated with obesity in young adulthood for females. Schools may serve as a primary setting for obesity prevention efforts. Because obesity in adolescence tracks into adulthood, it is important to consider prevention efforts at this stage in the life course, in addition to early childhood, particularly among disadvantaged populations. © 2013, American School Health Association.

    Little is known about how interpersonal friend relationships are associated with obesity in young people, particularly with regard to how race/ethnicity, type of friendship, and sex affect the association between friends' and adolescents' weight status. This study examined associations in weight status among adolescents and their friends, exploring magnitudes of associations across friendship type, sex, and race/ethnicity. As part of EAT-2010 (Eating and Activity in Teens), friend nominations and anthropometrics were obtained from adolescents (n = 2099: 54% female; 80% nonwhite; mean age: 14.2 ± 1.9 years). Generalized estimating equation logistic regression models were used to test associations between adolescents' overweight/obese status and friends' (i.e., friend group, female friends, male friends, female best friends, and male best friends) overweight/obese status. Interactions by adolescent race/ethnicity were examined. The majority of significant associations were observed among white female adolescents' who had a 22-40% higher prevalence of overweight/obesity if their friends were overweight compared to white females whose friends were not overweight. In contrast, there were few significant differences for other adolescent female and male racial/ethnic groups for girls and boys. Results for friend groups and best friends were generally similar to one another. The association between friend and adolescent overweight/obese status depended on adolescents' sex, race/ethnicity, and friendship type. Given the similarities among friends, obesity interventions targeting youth, especially white females, should consider involving friends.

    Over the past 30 years, the prevalence of overweight and obesity in children and adolescents has nearly tripled. Physical inactivity, unbalanced diet, and unhealthy lifestyles may cause lifelong obesity. A representative, national cross-sectional study was carried out between 2006 and 2007 with 40 middle high schools with 384 classes. We used a three-stage stratified systematic sampling design with a probability proportionate to the size from the northern, middle, southern, and eastern areas in Taiwan. Questionnaires were completed by 8640 students (51.7% boys and 48.3% girls) aged between 13 and 16 years. Obesity was identified in 7.2% of the participants and 16.1% were overweight. Using stepwise logistic regression, we found that those whose fathers or mothers were obese, watched television for more than 2 hours/day on weekdays and slept for less than 7.75 hours/day at weekends had a statistically significantly greater risk of obesity (females: ORs = 3.4, 4.2, 1.8, and 4.2, respectively; P leisure time and help them have sufficient sleep.

    Pediatric obesity is a growing public health concern that contributes to high rates of negative long-term physical and mental health outcomes. Research focused on identifying risk for pediatric obesity has linked delay discounting, or an inclination for immediate rewards, as well as weight concern to individuals with greater Body Mass Index (BMI). The current study seeks to fill a void in the literature by examining how these two variables interact to promote higher BMI in female adolescents. Adolescent (n=60) females between the ages of 13-19years (mage=17.45, SD=1.74) of age completed the Eating Disorder Examination Questionnaire (EDE-Q) and the Delay Discounting Questionnaire. A mediation model examined whether delay discounting accounted for the relationship between weight concern and BMI. Results indicate that in the current study weight concern was negatively related to delay discounting and delay discounting was negatively related to BMI. The overall model revealed that a partial mediation occurred [b=1.28, t(60)=4.92, pconcerns contribute to greater BMI. Nevertheless, the results indicate that prevention and interventions should identify females with high levels of both weight concern and impulsivity as an increased risk for experiencing pediatric obesity and long-term negative health outcomes.

    The main purpose of this study was to explore some of the social, dietary and lifestyle factors that could be related to the risk of obesity among adolescents in Bahrain. A multistage stratified method was used to select secondary school students (15-18years old) from governmental schools in Bahrain. The total sample selected was 735 (339 males and 396 females). A pre-validated self-report questionnaire was used to obtain information on socio-demographics, food and the lifestyle habits of adolescents. Weight and height were taken and percentiles of Body Mass Index for age and gender were used to classify the adolescents as non-obese and obese (overweight and obese), using NHANES-1 growth standard. In general, the prevalence of overweight and obesity was 29.5% and 36.8% among males and females, respectively. The risk of obesity was not consistent among male and female adolescents. Mothers' education was found to be a risk factor for obesity among both males and females (p=0.0167 and p=0.007, respectively). Bringing food from home to school (odds ratio (OR)=0.54, confidence interval (CI) 0.35-0.81) was protective factor for obesity among females but not among males. Fathers' education (p=0.0167), rank among siblings (p=0.009), place where breakfast is eaten (p=0.0398), eating between lunch and dinner (p=0.0152), fruit intake (p=0.042), sweet intake (p=0.0192), size of burger (p=0.002) and hours of watching television per day (p=0.004) were significantly associated with the risk of obesity among males, but not among females. Various social, dietary and lifestyle factors were found to contribute to obesity among adolescents in Bahrain. These factors should be considered in school health policy in the country.

    The implications of obesity in childhood and adolescence resonate into adulthood and have implications at different levels that include psychosocial and health issues that impact beyond reproductive performance. This chapter explores the various facets and consequences on gynaecological issues of increased Body Mass Index in childhood, including the link with puberty, pubertal menorrhagia (also affecting children with complex needs) and the all too common problems surrounding hyperandrogenism, insulin resistance and the polycystic ovarian syndrome in particular which need to be seen in the specific context of the adolescent years. The wider ramifications of obesity on the psychosocial welfare of adolescents merits special attention. Finally management strategies are considered in the context of the needs of adolescents.

    Obesity among children, adolescents and adults has emerged as one of the most serious public health concerns in the 21st century. The worldwide prevalence of childhood obesity has increased remarkably over the past 3 decades. The growing prevalence of childhood obesity has also led to appearance of obesity-related comorbid disease entities at an early age. Childhood obesity can adversely affect nearly every organ system and often causes serious consequences, including hypertension, dyslipidemia, insulin resistance, dysglycemia, fatty liver disease and psychosocial complications. It is also a major contributor to increasing healthcare expenditures. For all these reasons, it is important to prevent childhood obesity as well as to identify overweight and obese children at an early stage so they can begin treatment and attain and maintain a healthy weight. At present, pharmacotherapy options for treatment of pediatric obesity are very limited. Therefore, establishing a comprehensive management program that emphasizes appropriate nutrition, exercise and behavioral modification is crucial. The physician’s role should expand beyond the clinical setting to the community to serve as a role model and to advocate for prevention and early treatment of obesity. PMID:25241606

    Few studies have examined age or cultural differences in the stereotypes adolescents have of persons with obesity. The present research explored the hypotheses that American adolescents have more negative obesity stereotypes than Chinese adolescents and that the effects of culture are mediated by weight attributions and thin idealization. Participants (N = 335; 181 female; M age = 14.83 years, SD = 1.57 years) completed measures of thin idealization and causal attributions and made generalizations from and attributions of stereotypical personality characteristics to obese figures. Not only did stereotypes differ between countries, but generalizations of negative characteristics from obese figures increased with age. In addition, American adolescents more firmly endorsed the 'thin ideal' and were more likely to attribute obesity to internal causes that Chinese adolescents. As anticipated, between-country differences in stereotyping were mediated by thin idealization and causal attributions. Findings are discussed in terms of the 'doctrine of the mean', social identity theory, and dual-process theories. Statement of Contribution The development of obesity stereotypes has been the subject of a number of recent studies. Although scarce, research on adolescents' obesity stereotypes indicates that the strength of these stereotypes increases with age and that these increases are mediated by thin idealization and causal attributions. The current research adds to this growing literature that differences between Chinese adolescents' and American adolescents' obesity stereotypes - in terms of the assignment of stereotypical traits to people with obesity and the generalization of negative traits from an individual person with obesity to people with obesity as a group - are mediated by thin idealization and attributions about obesity's causes. The research also indicates that (1) age differences in obesity stereotyping vary as a function of the method used to measure

    This study aimed to investigate the association between obesity and major depression disorder (MDD) in a nationally representative sample of Black adolescents in the USA. The study also tested the effects of ethnicity and gender as possible moderators. Data came from the National Survey of American Life (NSAL)-Adolescents, a representative household mental health survey of Black adolescents in the USA. Participants consisted of 1170 Black adolescents (810 African Americans and 360 Caribbean Blacks). Obesity was defined determined by the cutoff points based on the body mass index (BMI) appropriate for age and gender. Twelve-month MDD was measured using the World Mental Health Composite International Diagnostic Interview (CIDI). In the first step, the association between obesity and MDD in the pooled sample, controlling for the main effects of gender and ethnicity. In the next steps, two interactions were tested: (1) obesity and ethnicity and (2) obesity and gender. Although any associations between obesity and MDD in the pooled sample of Blacks were not found, there was a significant interaction between ethnicity and obesity on MDD. Upon testing the associations across intersections of ethnicity and gender, a positive association was found among Caribbean Black females but not Caribbean Black males, African American males, or African American female. The link between BMI and MDD among Blacks depends on ethnicity and gender, and risk of comorbid depression among Black youth with obesity is highest among Caribbean Black females.

    Full Text Available Obesity is currently one of the major public health problems, in both developed and developing countries. Obesity is a risk factor for metabolic syndrome. Increasing rates of childhood obesity and more sedentary lifestyles has led to an age shift in metabolic syndrome which now occurs at an earlier age. Thus, the present study was conducted to get an idea about the occurrence of obesity among adolescent school children, risk factors associated with the condition and the related morbidity among them. MATERIALS AND METHODS: A cross-sectional descriptive study carried out in two higher secondary government girl schools with the help of a pre- designed and pre-tested questionnaire. RESULTS: Out of 245 students 16.73% were overweight and 6.54% were obese. Among overweight students, 59.65% exercised less than 4 hours a week, 61.4% watched TV ≥ 4 hours per week, 87.72% consumed junk food ≥ 4 days per week and 45.61% skipped meals. Puberty related menstrual irregularities, hypothyroidism, acne and stria were more commonly found in overweight students CONCLUSION: The rapidly increasing prevalence of obesity accompanied by unhealthy lifestyle habits among adolescents is one of the most challenging dilemmas of public health importance.

    Full Text Available Obesity, especially upper body fat distribution, has become an increasingly important medical problem in children and adolescents. Outcomes related to childhood obesity include, as in adult population, hypertension, type 2 diabetes mellitus, dyslipidemia, left ventricular hypertrophy, obstructive sleep apnea, orthopedic and socio-psychological problems. Obese children are at approximately 3-fold higher risk for hypertension from non-obese ones. Obesity-hypertension appears to be characterized by a preponderance of isolated systolic hypertension, increased heart rate and blood pressure variability, increased levels of plasma catecholamine and aldosterone, and salt-sensitivity. Lifestyle changes of weight loss, healthier diet and regular physical exercise are effective in obesity-hypertension control, though pharmacological treatment is frequently necessary. Screening for dyslipidemia and impaired glucose tolerance should be performed in paediatric patients with obese hypertension on regular basis, at least once annually or semiannually to discover metabolic syndrome and to prevent its increased cardiovascular risk. Of course, prevention of obesity is the primary goal. .

Fully adjusted linear regression models of the total sample produced results indicating that obesity was associated with BP (SBP: β = 7.08, P obesity were associated with SBP (overweight: β = 6.77, P obese: β = 11.65, P obesity was correlated with DBP (β = 9.86, P obesity was associated with DBP (β = 6.98, P obesity was significantly associated with SBP among adolescent females but not males. The relationship between weight status, familial hypertension and obesity status, and BP among adolescents vary by sex. This study underscores the need for additional research investigating the relationship between individual sex, weight status, BP and familial BP, and obesity status on risk among African American adolescents. © American Journal of Hypertension, Ltd 2017.

    The objective of this study was to assess the predictive value of body mass index (BMI) at earlier ages on risk of overweight/obesity at age of 11 years. This is a longitudinal study of 907 children from birth to age of 11 years. Predictors include BMI at earlier ages and outcome is overweight/obesity status at age of 11 years. Analyses were adjusted for covariates known to affect BMI. At 11 years, 17% were overweight and 25% were obese. Children whose BMI was measured as ≥85th percentile once at preschool age had a twofold risk for overweight/obesity at 11 years of age. Risk increased by 11-fold if a child's BMI measured was noted more than once during this age. During early elementary years, if a child's BMI was>85th percentile once, risk for overweight/obesity at 11 years was fivefold and increased by 72-fold if noted more than two times. During late elementary years, if a child's BMI was>85th percentile once, risk for overweight/obesity was 26-fold and increased by 351-fold if noted more than two times. Risk of overweight/obesity at 11 years was noted with higher maternal prepregnancy weight, higher birth weight, female gender and increased television viewing. Children in higher BMI categories at young ages have a higher risk of overweight/obesity at 11 years of age. Effect size was greater for measurements taken closer to 11 years of age. Pediatricians need to identify children at-risk for adolescent obesity and initiate counseling and intervention at earlier ages.

    Children and adolescents today are the first generation raised in a society in which technological literacy is essential for effective citizenship in the 21st century. With many more youth using digital technologies for educational and recreational purposes, there has been an increase in social problems in cyberspace, exposing them to different forms of cyberviolence. This article gives an overview of the developments in cyberspace, describes different types of cyberviolence, and focuses on cyberbullying among girls and adolescent females as both victims and perpetrators of cyberbullying. At-risk online activities among girls and adolescent females as well as strategies to promote cybersafety are presented. Current research and future directions for research are reviewed.

    Childhood and adolescent obesity has been increasing in most middle- and high-income countries, and, as with adult obesity, this has been driven by increasingly obesogenic environments, especially the food environment. This constitutes a "market failure," signaling the need for government interventions with policies, programs, and social marketing. Population prevention strategies are critical, and children and adolescents should be the priority populations. Food marketing to children is a central policy issue for governments to address, and comprehensive regulations are needed to provide substantive protection for children. Community-based intervention programs show some real promise in reducing childhood obesity, but the 2 big challenges ahead are to ensure that there is substantial ongoing funding so that the community capacity to promote healthy weights can be scaled up to a national level and to ensure that policies are in place to support these efforts. The social and cultural shifts that support healthy eating and physical activity occur differentially, and special efforts are needed to reduce the socioeconomic gradients associated with childhood obesity. A positive public health approach encompassing environmental, regulatory, sociocultural, and educational strategies offer the best chance of reducing obesity without increasing disordered eating patterns.

In a cross-sectional study of 174 girls, height, weight, waist circumference, Tanner stage, reproductive hormones, carbohydrate and lipid markers, drug use, and menstrual history were obtained at baseline. Exclusion criteria were menarcheal age PCOS or MeS classification. University medical center outpatient clinic. Ninety-eight girls ages 13-19.6 years, Tanner 5, average body mass index of 46.6 kg/m(2), menarche at 11.4 years, and average menarcheal age of 5 years. None. Polycystic ovary syndrome and MeS. Ninety-eight girls were divided into four groups: PCOS by National Institutes of Health criteria (PCOSN, n = 24), irregular menses only (n = 25), elevated T (≥55 ng/dL) only (n = 6), and obese controls (n = 43). Metabolic syndrome by modified Cook criteria affected 32 girls or 33% overall: 6 of 24 PCOSN, 7 of 25 irregular menses only, 4 of 6 elevated T only, and 15 of 43 obese controls. Polycystic ovary syndrome by National Institutes of Health criteria and its individual components were not associated with MeS after adjusting for body mass index. Unlike obese adults, PCOSN and its individual components were not associated with MeS in the untreated morbidly obese adolescent population.

    2011-04-01

    The increase in obesity among women in the lower income bracket in Brazil has been singled out as a priority issue in the field of Public Health today. Concern about future repercussions of obesity in the less privileged groups calls for an in-depth theoretical approach and the energetic definition of public policy for prevention and control of the affliction in these segments. In this respect, the scope of this work is to attempt to pinpoint some analytical categories in the phenomenon of obesity among the underprivileged female population in Brazil. Biological, socioeconomic and cultural factors appear to interact in the dynamics of female obesity in the context of poverty revealing the complexity of this problem. Public policies of job creation, social inclusion and gender equality in the labor market would appear to be more promising ways of tackling obesity in underprivileged females in Brazil.

    Severe obesity is the fastest growing subgroup of obesity in youth. We sought to explore the association between severe obesity and subclinical measures of cardiac and vascular structure and function in adolescents and young adults. This was a cross-sectional comparison of 265 adolescents and young adults with severe obesity (defined as body mass index [BMI] ≥120% of the 95th percentile) to 182 adolescents and young adults with obesity (defined as BMI ≥100-119th of the 95th percentile) at tertiary medical center. Noninvasive measures of cardiac and vascular structure and function were assessed. Participants were a mean age of 17.9 years, 62% were non-Caucasian, and 68% were female. Systolic blood pressure, fasting insulin, C-reactive protein, IL-6, and frequency of type 2 diabetes were higher in participants with severe obesity (all P obesity as measured by higher left ventricular mass index, worse diastolic function, higher carotid intima media thickness, and pulse wave velocity and lower brachial distensibility (all P obesity (compared with obesity) was independently associated with each of the above outcomes after adjustment for age, race, sex, blood pressure, lipids, and inflammatory markers (P young adults with severe obesity have a more adverse cardiovascular risk profile and worse cardiac and vascular structure and function. More importantly, severe obesity is independently associated with these subclinical cardiac and vascular changes.

    Because prenatal alcohol exposure is associated with growth deficiency, little attention has been paid to the potential for overweight and obesity in children with fetal alcohol spectrum disorders (FASD). This study examined the prevalence of overweight/obesity (body mass index [BMI]) in a large clinical sample of children with FASD. Children, aged 2 to 19 years, who were evaluated for FASD at University Clinics, included 445 with an FASD diagnosis and 171 with No-FASD diagnosis. Prevalence of overweight/obesity (BMI ≥ 85 percentile) was compared to national and state prevalence. BMI was examined in relation to FASD diagnosis, gender, and age. Dietary intake data were examined for a young subsample (n = 42). Thirty-four percent with any FASD diagnosis were overweight or obese, which did not differ from the No-FASD group or U.S. prevalence. Underweight was prevalent in those with fetal alcohol syndrome (FAS) (17%). However, increased rates of overweight/obesity were seen in those with partial FAS (40%). Among adolescents, those with any FASD diagnosis had increased overweight/obesity (42%), particularly among females (50%). The rate in adolescent females with FASD (50%) was nearly 3 times higher than state prevalence for adolescent females (17 to 18%), p overweight/obese consumed more calories, protein, and total fat per day than those who were not overweight or obese. Rates of overweight/obesity are increased in children with partial FAS. In adolescents, rates are increased for any FASD diagnosis (particularly in females). Results are suggestive of possible metabolic/endocrine disruption in FASD-a hypothesis for which there is evidence from animal models. These data suggest that clinicians may consider prenatal alcohol exposure as a risk factor for metabolic/endocrine disruption, should evaluate diet as a risk in this population, and may need to target interventions to females prior to puberty to effect changes in overweight-related outcomes.

    To report a retrospective analysis of data routinely collected in the course of healthcare services at a rural health clinic and to assess obesity incidence and associated interventions among rural Mexican-American adolescents. Two hundred and twelve charts reviewed; 98 (46.2%) males and 114 (53.8%) females. Data extracted included Medicaid exams conducted at the clinic within 5 years. Equal overweight or obese (n = 105, 49.5%), versus normal BMI categorizations (n = 107, 50.5%) documented overall and by gender. Female obesity higher (25.4%) than national norms (17.4%); male rates (25.5%) were within national norm. Interventions provided by nurse practitioners (94%) for 34.8%-80% of overweight/obese had limited follow-up (4%). Obesity incidence markedly increased between 13 and 18 years of age without associated interventions; 51.4%-75.6% without interventions. Obesity is a healthcare problem among rural Mexican-American adolescents accessing care at the rural health clinic. Obesity intervention and follow-up was suboptimal within this setting. Rural and ethnic minority adolescents experience health disparities concerning obesity prevalence and remote healthcare access. Obesity prevention and treatment during adolescence is a national health priority given physiologic and psychological tolls on health and potential for obesity into adulthood. Obesity assessment and translation of evidence-based interventions for rural Mexican-American adolescents at rural health clinics is implicated. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

    Full Text Available OBJECTIVE: To study anthropometrical and body composition variables as predictors of risk for metabolic alterations and metabolic syndrome in female adolescents.METHODS: Biochemical, clinical and corporal composition data of 100 adolescents from 14 to 17 years old, who attended public schools in Viçosa, Southeastern Brazil, were collected.RESULTS: Regarding nutritional status, 83, 11 and 6% showed eutrophia, overweight/obesity and low weight, respectively, and 61% presented high body fat percent. Total cholesterol presented the highest percentage of inadequacy (57%, followed by high-density lipoprotein (HDL - 50%, low-density lipoprotein (LDL - 47% and triacylglycerol (22%. Inadequacy was observed in 11, 9, 3 and 4% in relation to insulin resistance, fasting insulin, blood pressure and glycemia, respectively. The highest values of the fasting insulin and the Homeostasis Model Assessment-Insulin Resistance(HOMA-IR were verified at the highest quartiles of body mass index (BMI, waist perimeter, waist-to-height ratio and body fat percent. Body mass index, waist perimeter, and waist-to-height ratio were the better predictors for high levels of HOMA-IR, blood glucose and fasting insulin. Waist-to-hip ratio was associated to arterial hypertension diagnosis. All body composition variables were effective in metabolic syndrome diagnosis.CONCLUSIONS: Waist perimeter, BMI and waist-to-height ratio showed to be good predictors for metabolic alterations in female adolescents and then should be used together for the nutritional assessment in this age range.

    Full Text Available Obesity is a multifactorial disease. The aim of this study was to investigate the etiological factors contributing to the formation of obesity in children and adolescents. Study included two groups of children. Main group: 101 children with obesity aged 10 to 17 years, body mass index (BMI 31,27±0,51 kg/m 2. Comparison group: of 14 children aged 10 to 17 years, without obesity, BMI 18,54±0,11 kg/m 2. In all children we evaluated perinatal and family history, lifestyle and diet, anthropometric parameters, assessed the progress of sexual development. We found that the manifestation of the disease occurred in the early school years, and in boys significantly earlier than in girls. Mothers of obese children had complications during pregnancy (such as toxaemia, the risk of miscarriage, hypertension, previous medical abortions. The children in the majority of cases were early nursed on milk formula, had violations in feeding regime, and hypokinesia. The disease was shown to run in families.

    This study examines individual and family characteristics of a population of 29 adolescent females charged with homicide or attempted homicide in the juvenile justice system. The purpose of this study is to contribute to the limited knowledge about adolescent females charged with homicide. Data were collected including the MAYSI-2, a risk classification instrument, and social, educational and family histories. Findings include high rates of reported substance use, delinquent peers, early indicators of mental health problems, and limited control and supervision by parents. The most common weapon used was a car and the most common victim was a known person. A comparison was conducted on girls charged with homicide during the commission of another crime or committed during a conflict. The conflict group was found to victimize friends and family significantly more often than the crime group. The crime group showed higher use of alcohol and drugs, used a gun more and had co-offenders at a higher rate. A profile was developed to describe the typical adolescent female homicide offender found in this study. Treatment recommendations and future research were discussed.

    Individual behaviour change to reduce obesity requires awareness of, and concern about, weight. This paper therefore describes how young adults, known to have been overweight or obese during early adolescence, recalled early adolescent weight-related awareness and concerns. Associations between recalled concerns and weight-, health- and peer-related survey responses collected during adolescence are also examined. Qualitative semi-structured interviews with young adults; data compared with responses to self-report questionnaires obtained in adolescence. A total of 35 participants, purposively sub-sampled at age 24 from a longitudinal study of a school year cohort, previously surveyed at ages 11, 13 and 15. Physical measures during previous surveys allowed identification of participants with a body mass index (BMI) indicative of overweight or obesity (based on British 1990 growth reference) during early adolescence. Overall, 26 had been obese, of whom 11 had BMI99.6th centile, whereas 9 had been overweight (BMI=95th-97.9th centile). Qualitative interview responses describing teenage life, with prompts for school-, social- and health-related concerns. Early adolescent self-report questionnaire data on weight-worries, self-esteem, friends and victimisation (closed questions). Most, but not all recalled having been aware of their overweight. None referred to themselves as having been obese. None recalled weight-related health worries. Recollection of early adolescent obesity varied from major concerns impacting on much of an individual's life to almost no concern, with little relation to actual severity of overweight. Recalled concerns were not clearly patterned by gender, but young adult males recalling concerns had previously reported more worries about weight, lower self-esteem, fewer friends and more victimisation in early adolescence; no such pattern was seen among females. The popular image of the unhappy overweight teenager was not borne out. Many obese

  11. Weight Misperceptions and Racial and Ethnic Disparities in Adolescent Female Body Mass Index

    2012-01-01

    Full Text Available This paper investigated weight misperceptions as determinants of racial/ethnic disparities in body mass index (BMI among adolescent females using data from the National Survey of Youth 1997. Compared to their white counterparts, higher proportions of black and Hispanic adolescent females underperceived their weight status; that is, they misperceived themselves to have lower weight status compared to their clinically defined weight status. Compared to their black counterparts, higher proportions of white and Hispanic adolescent females misperceived themselves to be heavier than their clinical weight status. Oaxaca-Blinder decomposition analysis showed that accounting for weight misperceptions, in addition to individual and contextual factors, increased the total explained portion of the black-white female BMI gap from 44.7% to 54.3% but only slightly increased the total explained portion of the Hispanic-white gap from 62.8% to 63.1%. Weight misperceptions explained 13.0% of the black-white female BMI gap and 3.3% of the Hispanic-white female BMI gap. The regression estimates showed that weight underperceptions were important determinants of adolescent female BMI, particularly among black and Hispanic adolescents. Education regarding identification and interpretation of weight status may play an important role to help reduce the incidence and racial disparity of female adolescent obesity.

    Obesity is increasing in developed as well as in developing countries. This analytical cross sectional study was carried out to document the relation between blood pressure, serum creatinine and body mass index in female and to assess potential health differences among obese female and normal weight female. This study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2012 to June 2013. Seventy female persons volunteered as subjects. Among them 35 were within normal weight (BMI 18.5-24.9kg/m²) and 35 were obese (BMI≥30kg/m²). Non probability purposive type of sampling technique was used to select the subjects. Measurement of body mass index and blood pressure were done as per procedure. Serum creatinine level was estimated by enzymatic colorimetric method. The results were calculated and analyzed by using SPSS (statistical package for social science, version 17.0), scientific electronic calculator and simultaneously with a computer assisted program like Microsoft excel. Unpaired 't' test was applied to find the significance of difference regarding serum creatinine and blood pressure levels in obese female. The value of p was 1% to indicate highly significant and 5% to indicate simply significant or statistically significant. The mean±SE of systolic blood pressure, diastolic blood pressure and serum creatinine levels were 135.71±1.58mmHg, 88.74±0.95mmHg and 1.03±0.01mg/dl respectively; significant at 1% level for obese group of BMI (phigh BMI is significantly related to increased levels of serum creatinine & blood pressure in obese female which indicate the obese subjects are prone to cardiovascular & metabolic risk.

    To determine if adolescent obesity is associated with parenting characterized by lower sensitivity and lower monitoring of adolescent activities. We used data from 744 adolescents in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Height and weight were measured at age 15½ years and obesity defined as body mass index ≥ 95th percentile for age and sex. Maternal and paternal sensitivity were assessed by direct observation of a parent-adolescent interaction task. Maternal and paternal monitoring were assessed by parent report. Lower sensitivity and lower monitoring were each defined as the lowest quartiles. Two separate multivariate logistic regression models were created to evaluate, individually for mothers and fathers, associations of sensitivity and monitoring with adolescent obesity, controlling for adolescent sex and race, family income-to-needs ratio, and parental obesity. Fourteen percent of the adolescents were obese. Lower sensitivity was associated with adolescent obesity in the maternal parenting model (adjusted odds ratio [AOR] 2.36, 95% confidence interval [CI] 1.44-3.86, n = 709), but not paternal parenting model (AOR = 0.79, 95% CI 0.38-1.63, n = 460). Neither maternal nor paternal monitoring was associated with adolescent obesity (AOR = 1.03, 95% CI 0.63-1.68; AOR = 1.07, 95% CI 0.52-2.22, respectively). Lower maternal sensitivity, measured by direct observation of parent-adolescent interactions, was associated with adolescent obesity. Efforts to prevent and treat childhood obesity, both at the practitioner level and the community level, may be enhanced by educating parents that their reactions to their children's behaviors may have consequences related to obesity.

    Full Text Available Abstract Background The joint impact of sedentary behavior and physical activity on obesity has not been assessed in a large cohort followed from adolescence to adulthood. Methods Nationally representative longitudinal data from Waves II (1995; mean age: 15.9 and III (2001; mean age: 21.4 of the National Longitudinal Study of Adolescent Health (n = 9,155 were collected. Sex-stratified multivariate logistic regression analysis assessed the odds of obesity associated with Wave II MVPA and screen time, controlling for sociodemographic characteristics and change in MVPA and screen time from Wave II to III. Obesity was defined using body mass index (BMI, kg/m2 International Obesity Task Force cut-points at Wave II and adult cut-points at Wave III (BMI ≥ 30. Results In males, adjusted odds of prevalent obesity was strongly predicted by MVPA bouts [OR (95% CI: OR6 vs. 1 MVPA bouts = 0.50 (0.40, 0.62; OR4 vs. 40 hrs screen time = 0.83 (0.69, 1.00]. In females, greater MVPA bouts and lower screen time correlated with lower prevalent obesity [OR (95% CI: OR6 vs. 1 MVPA bouts = 0.67 (0.49, 0.91; OR4 vs. 40 hrs screen time = 0.67 (0.53, 0.85]. Longitudinally, adolescent screen time hours had a stronger influence on incident obesity in females [OR (95% CI: OR4 vs. 40 hrs = 0.58 (0.43, 0.80] than males [OR (95% CI: OR4 vs. 40 hrs = 0.78 (0.61, 0.99]. Longitudinal activity patterns were not predictive of incident obesity. Conclusion Reducing screen time during adolescence and into adulthood may be a promising strategy for reducing obesity incidence, especially in females.

    The objective was to explore obese adolescents perceptions about obesity among students in the seventh to ninth grade of a public school in Tamaulipas, Mexico. This is a qualitative study. Participants were 24 adolescents with a body mass index equal to or greater than the 95th percentile. Semistructured interviews were conducted until data saturation was reached and the meaning was understood. The adolescents defined obesity according to standards of measurement. They identified the hereditary factor as the main obesity cause, tended to underestimate obesity and had low self-esteem. They reported problems to do physical exercise and get clothes in order to improve their image, and feel rejected by their peers in school. It was identified that these adolescents have psychological defense mechanisms against obesity and that some of them are making efforts to lose weight. Obesity entails social and psychological health implications for persons suffering from this problem. Interventions should be put in practice.

    The aim of this study was to investigate fat distribution, mainly abdominal fat, and its relationship with metabolic risk variables in a group of 126 children and adolescents (60 males and 66 females) aged 5.0 to 14.9. According to IOTF criteria, 46 were classified as normal weight, 28 overweight and 52 obese. Weight, height, waist (WC) and hip circumferences were measured. The body mass index (BMI) was calculated. Total body fat, trunkal and abdominal fat were also assessed by dual energy x-ray absorptiometry (DXA). Glucose, insulin, HDL-Cholesterol, triglycerides (TG), ferritine, homocystein and C-reactive protein (CRP) were measured. Obesity status was related with insulin concentrations, CRP, TG and HDL. Obese patients had higher abdominal fat and higher CRP values than overweight and normal subjects. All markers of central body adiposity were related with insulin and lipid metabolism; however, they were not related with homocystein or ferritin. A simple anthropometric measurement, like waist circumference, seems to be a good predictor of the majority of the obesity related metabolic risk variables.

    Aim: To determine the influence of physical activity (PA) and sedentary behavior (SB) on obesity profiles of 454 Malaysian adolescents aged 12 to 19. Methods: Validated PA and SB questionnaires were used and body composition assessed using anthropometry and dual-energy X-ray absorptiometry (DXA). Results: Gender-specific multivariate analyses showed boys with high levels of total PA and moderate-to-vigorous physical activity (MVPA) exhibited significantly lower levels of total body fat, percent body fat and android fat mass compared with low PA and MVPA groups, after adjusting for potential confounders. Girls with high SB levels showed significantly higher BMI, waist circumference and DXA-derived body fat indices than those at lower SB level. Multiple logistic analyses indicated that boys with low levels of total PA and MVPA had significantly greater obesity risk, 3.0 (OR 3.0; 95% CI, 1.1–8.1; p obesity, 2.9 times higher than girls at low SP levels (OR 2.8; 95% CI, 1.0–7.5; p obesity risk while high screen-based sedentary behaviors significantly adversely influenced body fat mass, particularly amongst girls when the PA level was low.

    To evaluate the presence of insulin resistance and its association with other metabolic abnormalities in obese children and adolescents. Retrospective study of 220 children and adolescents aged 5-14 years. Anthropometric measurements were performed (weight, height, and waist circumference) and clinical (gender, age, pubertal stage, and degree of obesity) and biochemical (glucose, insulin, total cholesterol, and fractions, triglycerides) data were analyzed. Insulin resistance was identified by the homeostasis model assessment for insulin resistance (HOMA-IR) index. The analysis of the differences between the variables of interest and the HOMA-IR quartiles was performed by ANOVA or Kruskal-Wallis tests. Insulin resistance was diagnosed in 33.20% of the sample. It was associated with low levels of high-density lipoprotein cholesterol (HDL-C; p=0.044), waist circumference measurement (p=0.030), and the set of clinical and metabolic (p=0.000) alterations. Insulin-resistant individuals had higher mean age (p=0.000), body mass index (BMI; p=0.000), abdominal circumference (p=0.000), median triglycerides (p=0.001), total cholesterol (p≤0.042), and low-density lipoprotein cholesterol (LDL-C; p≤0.027); and lower HDL-C levels (p=0.005). There was an increase in mean BMI (p=0.000), abdominal circumference (p=0.000), and median triglycerides (p=0.002) as the values of HOMA -IR increased, with the exception of HDL-C, which decreased (p=0.001). Those with the highest number of simultaneous alterations were between the second and third quartiles of the HOMA-IR index (p=0.000). The results confirmed that insulin resistance is present in many obese children and adolescents, and that this condition is associated with alterations that represent an increased risk for developing metabolic disorders in adulthood.

    Full Text Available This article came from the monographic study “Resilience and Sexual Violence: a study of adolescents victimized by sexual abuse assistance” (MARANHÃO, 2008, in which was investigated the building resilience in victimized adolescents. Resilience is characterized as overcoming adversity, setting up as something procedural, promoted by the interaction of personal and collective protection, in particular context of risk or social vulnerability. We made the trimming about the meanings and feelings of sexual victimization within the family from the perception of adolescents between 12 and 16 years of age that received care in a Specialized Reference Social Assistance in 2010. The research is qualitative, having as theoretical-methodological referential the Historic-Cultural Theory. Data collection was used by semi-structured interview. We realize that the profile of the victims are set up by females, the beginning of sexual abuse occurred between childhood and preadolescence. The profile of perpetrators are men, adults, acting the role of the stepfather, father and uncle. Despite an abject sense, adolescents could not break the cycle of violence. Friends, extended family, and the work of professionals emerged as support for the redefinition of the abusive relationships.

    To analyse the relationship between the frequency of family meals and the body weight of 13-year-olds and its selected determinants. The study was conducted in 2008 as the last stage in a prospective cohort study of 605 children. Questionnaires containing questions about the frequency of family meals, the general regularity of meals, fruit and vegetable consumption, physical activity and the number of hours spent watching television or at the computer were sent to 13-year-olds by mail. School nurses performed anthropometric measurements of the pupils' weight and height. Statistical analyses were performed, i.e. Pearson's correlations, the two-step cluster analysis and the logistic regression analysis. Most of the young people (80-90%) eat each of the main meals in the company of their parents at least once a week, 21% have breakfast with their parents every day, 41% - dinner, and 45% - supper. The frequency of family meals correlated negatively with the girls' BMI and the number of hours they spent watching television or at the computer, while positively with physical activity, regular meals and vegetable consumption in adolescents of both genders. The lowest mean values of BMI were found in a group of adolescents often eating family meals, the highest - in the group of young people who rarely ate family meals (over 20% of young people in this group were overweight), but the differences were statistically significant only for girls (p=0.025). The probability of less than 2 hours of sedentary behaviour daily, physical activity of at least 60 minutes per day and everyday vegetable and fruit consumption is twice as high in adolescents often consuming meals with their parents, and with the daily consumption of all the meals in this way - more than fourfold higher than in other groups. Family meals treated as a predictor of a healthy lifestyle can indirectly protect adolescents from overweight and obesity. Promoting family meals should be an important method of

    Full Text Available Being overweight or obese is one of the most common reasons that children and adolescents are teased at school. We carried out a study in order to investigate: i the relation between weight status and school bullying and ii the relation between weight status categories and types of victimization and bullying in an outpatient sample of Italian children and adolescents with different degrees of overweight from minimal overweight up to severe obesity.Nine-hundred-forty-seven outpatient children and adolescents (age range 6.0-14.0 years were recruited in 14 hospitals distributed over the country of Italy. The participants were classified as normal-weight (N = 129, overweight (N = 126, moderately obese (N = 568, and severely obese (N = 124. The nature and extent of verbal, physical and relational bullying and victimization were assessed with an adapted version of the revised Olweus bully-victim questionnaire. Each participant was coded as bully, victim, bully-victim, or not involved.Normal-weight and overweight participants were less involved in bullying than obese participants; severely obese males were more involved in the double role of bully and victim. Severely obese children and adolescents suffered not only from verbal victimization but also from physical victimization and exclusion from group activities. Weight status categories were not directly related to bullying behaviour; however severely obese males perpetrated more bullying behaviour compared to severely obese females.Obesity and bullying among children and adolescents are of ongoing concern worldwide and may be closely related. Common strategies of intervention are needed to cope with these two social health challenges.

    In the past few decades, there has been an overwhelming increase in childhood and adolescent obesity worldwide. Besides the well recognized cardiometabolic complications and other physical conditions associated with obesity, during adolescence, it causes psychological and social distress in a period of life that is already sensitive for a girl. This in turn increases their risk of low self-esteem and depression. Furthermore, obesity diminishes health-related quality of life and years of life. Overweight and obese teenagers are more likely to have gynecologic and obstetric complications, during adolescence and also later in life. Consequences of obese and overweight childhood and adolescence include sexual maturation and reproductive dysfunction, alterations in menstruation, dysmenorrhea, risky sexual behavior, and inefficient use of contraception, polycystic ovary syndrome, bone density abnormalities, macromastia, and an increased risk of breast and endometrial cancer. Obese adolescents are at greater risk of pregnancy and perinatal complications, such as preeclampsia, gestational hypertension and preeclampsia, gestational diabetes mellitus, primary cesarean delivery, and induction of labor, to mention a few. Evidence shows that infants born to obese teenagers are also more likely to have complications including preterm or post-term delivery, small-for-gestational age newborns, macrosomia, meconium aspiration, respiratory distress, and even stillbirth, among others. This comprehensive review focuses on the gynecological and obstetric consequences of obesity in adolescent girls. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

    Background Weight loss does not necessarily decrease the negative appraisal of a formerly overweight individual. Since past weight history tends to be disclosed in several contexts, this study aims to investigate whether negative appraisals are gender-specific and if they are modulated by the evaluators’ own BMI. Methods 202 young adults (106 male and 96 female) viewed a picture of a young attractive female (target) accompanied by one of two statements about her past weight (overweight (OW) or always kept a normal weight (NW)), and then rated her using the Fat Phobia Scale (FPS). Results Female evaluators rated the target with the OW statement more negatively than the target with the NW statement. In contrast, males exposed to the OW statement rated the target as having fewer emotional/psychological problems and being less stupid/uncreative. BMI only influenced ratings in males, where those with higher BMI ascribed more negative attributes to the target with the NW statement than the OW statement. Conclusion Information on weight history impacts upon the appraisal of peers. These effects are dependent on gender and BMI. Knowing that a young female was overweight triggered negative evaluations from females but did not appear to impact the judgment of males. PMID:24107842

    Requests for assistance in menstrual management and menstrual suppression are a common, emotive and sometimes controversial aspect of adolescent disability care. To review the uptake and outcomes of menstrual suppression among adolescent patients with developmental delay. A retrospective review of the medical records of adolescent females with intellectual disability referred for menstrual management to the Paediatric and Adolescent Gynaecology Clinic, Children's Hospital at Westmead, Sydney, for the three-year period between January 1, 2010 and January 1, 2013. Eighty adolescent patients with developmental delay were identified. A third (n = 28) of the patients were pre-menarcheal at first review with parent/caregivers seeking anticipatory advice. Of the post-menarcheal patients, the median age of menarche was 12 years (range 10-15 years). First and second line interventions were documented as were reasons for change where applicable. The combined oral contraceptive pill (COCP) was the most frequently used therapy (67%), and 19 patients in total had a levonorgestrel releasing intrauterine system (LNG-IUS) inserted (31%). Our study population differs from similar previously published groups in the marked absence of the use of depot medroxyprogesterone acetate or the subdermal etonogestrel releasing device. As a paediatrician, it is important to address menstrual management issues and allay caregiver concerns with appropriate advice. Our study supports the use of the COCP as sound first line management in achieving menstrual suppression. The LNG-IUS appears to be a favourable second line option. Further investigation into longer-term outcomes and potential complications of device insertion is recommended. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Full Text Available Background Obesity is a global problem. Even in poor and developing countries, obesity has reached alarming levels. In childhood, obesity may lead to insulin resistance. Retinol binding protein (RBP4, secreted primarily by liver and adipose tissues, was recently proposed as a link between obesity and insulin resistance. The role of RBP4 in pediatric obesity and its relationship with insulin resistance have not been well elucidated. Objective To compare RBP4 levels in obese and lean adolescents and to assess for a relationship between RBP4 levels and insulin resistance. Method This cross-sectional study was conducted in three senior high schools in Padang, West Sumatera, Indonesia. Subjects were adolescents aged 14-18 years, who were obese or normal weight (n=56. We measured subjects’ body mass index (BMI and serum RBP4 concentrations. Insulin resistance was assessed using the homeostasis model assessment of insulin resistance (HOMA-IR index. Results Similar RBP4 levels were found in the obese and normoweight groups (P>0.05. Higher RBP4 levels were found in the insulin resistant compared to the non-insulin resistant group, but the difference was not significant (P > 0.05. Conclusion There is no significant difference in mean RBP4 levels in obese adolescents compared to normoweight adolescents. Nor are mean RBP4 levels significantly different between obese adolescents with and without insulin resistance.

    Obesity levels have been dramatically increased in the United Arab Emirates over the last few years. High levels of body Mass Index, waist circumference, and percent of total body fat as a measure of obesity have found to be related to cardiovascular risk factors and other diseases. Neck circumference is a new tool that has been linked to obesity. However, no studies in UAE have been conducted yet. The purpose of this study was to measure the obesity levels in a college population and to correlate them with NC and other anthropometrical indexes. Two hundred forty three (243) female students aged 18-25 were conveniently selected to participate in the study. Anthropometrical indexes were obtained from all subjects e after fasting. The prevalence of overweight and obesity together was found to be 28.4 % (n = 69). Pearson correlation showed that WC, NC and BF (%) were significantly positively related to obesity, (r = 0.790; r = 0.758; r = 0.767, p obesity. NC was found to be independently associated with obesity levels in Emirati college students.

    To evaluate adolescents' perception of the causes of obesity, with emphasis on differences according to nutritional status and socioeconomic position. We conducted qualitative research including 80 adolescents belonging to the 1993 Pelotas (Brazil) Birth Cohort Study, and their mothers. We classified adolescent boys and girls into four groups (girls-obese, girls-eutrophic, boys-obese, and boys-eutrophic) according to body mass index for age and sex, and systematically selected them according to family income at age 15 years. Research techniques included semistructured interviews and history of life. Topics covered in the interviews included early experiences with weight management, effect of weight on social relationships, family history, eating habits, and values. Low-income obese adolescents and their mothers perceive obesity as a heritage, caused by family genes, side effects of medication use, and stressful life events. However, low-income eutrophic adolescents emphasize the role of unhealthy diets on obesity development. Among the high-income adolescents, those who are obese attribute it to genetic factors and emotional problems, whereas those who are eutrophic mention unhealthy diets and lack of physical activity as the main causes of obesity. Perceptions of the causes of obesity in adolescents from a middle-income setting vary by gender, socioeconomic position, and nutritional status. Whereas some blame genetics as responsible for obesity development, others blame unhealthy diets and lifestyles, and others acknowledge the roles of early life experiences and family traditions in the process of obesity development.

    In spite of the lack of a uniform definition for metabolic syndrome in pediatry, recent studies have shown that it develops during childhood and is highly prevalent among children and adolescents who suffer from obesity. In light of the current epidemic of obesity in this age category in western countries, and specifically in Mexico, it becomes essential to know the means to prevent, detect and treat this syndrome. Nurses play an important role in promoting childhood health with regards to metabolic syndrome. To put into practice the strategies which resolve underlying problems related with this syndrome is a priority for the well-being of this age group. These strategies should include the application and management of public policies; the collaboration by health services, social services and schools; but, furthermore, the prevention and the management of this syndrome require a family commitment, while the changes in living habits benefit the entire family. This review article proposes to introduce prevention, diagnostic and treatment strategies which nursing personnel can carry out while dealing with metabolic syndrome in adolescents.

    In Western countries, obesity is a common problem in children with congenital heart disease (CHD). However, this problem may have racial difference, and little is known about the shift of this trend as patients grow up. The present study sought to investigate the prevalence and trends of being underweight, overweight and obesity in an Asian CHD cohort using a 5-year citywide school survey database. Patient group consisted of 705 first grade elementary school students (children) and 219 first grade senior high school students (adolescents), while 18753 healthy children and 15014 healthy adolescents served as controls. Body mass index (BMI) percentile was calculated to define underweight (BMI obesity (BMI ≥ 95(th) percentile). In CHD children, the prevalence of underweight and overweight/obesity was 21.0% (control 16%, P obese than children with non-cyanotic CHD. The prevalence of underweight (23.3%) and overweight/obesity (26.5%) in CHD adolescents became close to that in controls. From childhood to adolescence, different shifts in BMI distribution were noted; controls became more underweight and overweight/obese for males and more underweight and less overweight/obese for females, while CHD patients became more overweight/obese for both genders, including cyanotic CHD. In this Asian CHD cohort, we demonstrates a shift of BMI distribution from more underweight and less overweight/obese compared with healthy children, to a pattern similar to that in healthy adolescents. © 2012 Blackwell Publishing Ltd.

    The prevalence of obesity in childhood and adolescence has increased in Mexico. This increase can be explained partly by a decrease in physical activity. The objective of this study was to assess the association between the prevalence of obesity and overweight with physical activity and inactivity among Mexican adolescents. We analyzed data from a longitudinal study with baseline and follow-up measures in 446 adolescents 12 to 17 years old, attending public schools in Cuernavaca, Morelos, Mexico. We collected information on weight, physical activity and demographic characteristics. Obesity and overweight were determined using as indicador the body mass index, and the cutoff points proposed by the International Obesity Task Force. The baseline prevalence of obesity or overweight was 37.22% (42.99% for males and 30.95% for females), and in the final measure 34.30% (38.46% for males and 32.28% for females). The median time of TV viewing was 3.90 h/d, with 0.73 h/d dedicated to vigorous physical activity and 0.58 h/d to moderate physical activity. Using logistic regression, after adjustment for obesity in the baseline measure, sex and clustering by school, we found no significant associations between the prevalence of obesity or overweight with time dedicated to TV viewing, vigorous or moderate physical activity. However, when conducting the analysis with an interaction term by sex, we found significantly lower risk of obesity or overweight associated with an increase in vigorous physical activity among males only (beta = 0.22, 95% CI (0.05, 0.89). Results suggest that vigorous physical activity may reduce the risk of obesity or overweight among male adolescents.

    Evidence shows that surgery for severe obesity in adults improves health and psychological functioning, and is cost-effective. Data on bariatric surgery for adolescents with severe obesity are extremely limited, with no evidence on cost-effectiveness. We evaluated the lifetime cost-effectiveness of bariatric surgery compared with no surgery in adolescents with severe obesity from the UK's National Health Service perspective. Eighteen adolescents with body mass index ≥40 kg m -2 who underwent bariatric surgery (laparoscopic Roux en Y Gastric Bypass [RYGB] [N = 9], and laparoscopic Sleeve Gastrectomy [SG] [N = 9]) at University College London Hospitals between January 2008 and December 2013 were included. We used a Markov cohort model to compare the lifetime expected costs and quality-adjusted life years (QALYs) between bariatric surgery and no surgery. Mean cost of RYGB and SG procedures were £7100 and £7312, respectively. For RYGB vs. no surgery, the incremental cost/QALY was £2018 (95% CI £1942 - £2042) for males and £2005 (95% CI £1974 - £2031) for females. For SG vs. no surgery, the incremental cost/QALY was £1978 (95% CI £1954 - £2002) for males and £1941 (95% CI £1915 - £1969) for females. Bariatric surgery in adolescents with severe obesity is cost-effective; it is more costly than no surgery however it markedly improved quality of life. © 2017 World Obesity Federation.

    Severe obesity affects 4% to 6% of US youth and is increasing in prevalence. Bariatric surgery for the treatment of adolescents with severe obesity is becoming more common, but data on cost-effectiveness are limited. To assess the cost-effectiveness of bariatric surgery for adolescents with obesity using recently published results from the Teen-Longitudinal Assessment of Bariatric Surgery study. A state-transition model was constructed to compare 2 strategies: no surgery and bariatric surgery. In the no surgery strategy, patients remained at their initial body mass index (calculated as weight in kilograms divided by height in meters squared) over time. In the bariatric surgery strategy, patients were subjected to risks of perioperative mortality and complications as well as initial morbidity but also experienced longer-term quality-of-life improvements associated with weight loss. Cohort demographic information-of the 228 patients included, the mean (SD) age was 17 (1.6) years, the mean (range) body mass index was 53 (34-88), and 171 (75.0%) were female-surgery-related outcomes, and base case time horizon (3 years) were based on data from the Teen-Longitudinal Assessment of Bariatric Surgery study. One-way and probabilistic sensitivity analyses were performed. Quality-adjusted life-years (QALYs), total costs (in US dollars adjusted to 2015-year values using the Consumer Price Index), and incremental cost-effectiveness ratios (ICERs). A willingness-to-pay threshold of $100 000 per QALY was used to assess cost-effectiveness. After 3 years, surgery led to a gain of 0.199 QALYs compared with no surgery at an incremental cost of $30 747, yielding an unfavorable ICER of $154 684 per QALY. When the clinical study results were extrapolated to 4 years, the ICER decreased to $114 078 per QALY and became cost-effective by 5 years with an ICER of $91 032 per QALY. Outcomes were robust in most 1-way and probabilistic sensitivity analyses. Bariatric surgery incurs

    Full Text Available The global prevalence of overweight and obesity in children and adolescents has increased substantially over the past several decades. These trends are also visible in developing economies like India. Childhood obesity impacts all the major organ systems of the body and is well known to result in significant morbidity and mortality. Obesity in childhood and adolescence is associated with established risk factors for cardiovascular diseases and accelerated atherosclerotic processes, including elevated blood pressure (BP, atherogenic dyslipidemia, atherosclerosis, metabolic syndrome, type II diabetes mellitus, cardiac structural and functional changes and obstructive sleep apnea. Probable mechanisms of obesity-related hypertension include insulin resistance, sodium retention, increased sympathetic nervous system activity, activation of the renin-angiotensin-aldosterone system and altered vascular function. Adiposity promotes cardiovascular risk clustering during childhood and adolescence. Insulin resistance has a strong association with childhood obesity. A variety of proinflammatory mediators that are associated with cardiometabolic dysfunction are also known to be influenced by obesity levels. Obesity in early life promotes atherosclerotic disease in vascular structures such as the aorta and the coronary arteries. Childhood and adolescent adiposity has strong influences on the structure and function of the heart, predominantly of the left ventricle. Obesity compromises pulmonary function and increases the risk of sleep-disordered breathing and obstructive sleep apnea. Neglecting childhood and adolescent obesity will compromise the cardiovascular health of the pediatric population and is likely to result in a serious public health crisis in future.

    Full Text Available Aim: To determine the influence of physical activity (PA and sedentary behavior (SB on obesity profiles of 454 Malaysian adolescents aged 12 to 19. Methods: Validated PA and SB questionnaires were used and body composition assessed using anthropometry and dual-energy X-ray absorptiometry (DXA. Results: Gender-specific multivariate analyses showed boys with high levels of total PA and moderate-to-vigorous physical activity (MVPA exhibited significantly lower levels of total body fat, percent body fat and android fat mass compared with low PA and MVPA groups, after adjusting for potential confounders. Girls with high SB levels showed significantly higher BMI, waist circumference and DXA-derived body fat indices than those at lower SB level. Multiple logistic analyses indicated that boys with low levels of total PA and MVPA had significantly greater obesity risk, 3.0 (OR 3.0; 95% CI, 1.1–8.1; p < 0.05 and 3.8-fold (OR 3.8; 95% CI, 1.4–10.1; p < 0.01, respectively, than more active boys. Only in girls with high SB level was there a significantly increased risk of obesity, 2.9 times higher than girls at low SP levels (OR 2.8; 95% CI, 1.0–7.5; p < 0.05.  Conclusions: The present findings indicate that higher PA duration and intensity reduced body fat and obesity risk while high screen-based sedentary behaviors significantly adversely influenced body fat mass, particularly amongst girls when the PA level was low.

    Obesity in adolescents is prevalent worldwide. Polycystic ovary syndrome (PCOS) is often associated with obesity in women, and it has serious metabolic and reproductive health implications. Although PCOS does not become clinically visible until early adolescence, its origins are likely much earlier....... Therefore, we reviewed the recent literature regarding the mechanisms linking the development of PCOS and obesity in adolescent girls. We found that excess abdominal adipose tissue (AT) initiates metabolic and endocrine aberrations that are central in the progression of PCOS. As an example, abdominal...

    To investigate the inter-relationships between adipocytokines, oxidative stress, insulin, Zn and Cu and obesity among Egyptian obese non-diabetic children and adolescents. 72 obese children and adolescents of both sexes (5-17 years) were recruited for the study. 40 healthy normal non-obese persons of matched ages and sexes were used as control group. Lipid profile, tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6) and leptin levels were measured. Malondialdehyde (MDA) and reduced glutathione (GSH) concentrations and superoxide dismutase (SOD) activity were estimated. Micronutrients (Zn and Cu) concentrations in addition to insulin and fasting blood sugar (FBS) levels were also evaluated. Estimation of insulin resistance (homeostatic model assessment (HOMA-IR)) was derived from FBS measurements. Significant elevations (Pobese individuals as compared with control group. Insulin and triglyceride levels were significantly increased in obese male children and HDL-cholesterol level was increased significantly in obese adolescent females compared to controls. However, total cholesterol and LDL-cholesterol levels were significantly high in all obese cases as compared with controls. Insulin resistance was detected in 100% of the patients. We concluded that obesity with pro-inflammatory adipocytokines and hypozincemia together by many mechanisms participate in excessive oxidative stress and are highly associated with inflammation and the development of obesity-related complications. Obesity represents a critical risk factor for development of insulin resistance status. Copyright © 2015 Medical University of Bialystok. Published by Elsevier Urban & Partner Sp. z o.o.

    Obesity is a serious public health problem especially among adolescents. Understanding adolescents' attitudes toward obesity and healthy lifestyle is a crucial step to develop effective health programs to treat and prevent obesity. To examine the attitudes toward overweight and obesity among Jordanian adolescent students and to identify the components of obesity prevention program that the students perceive as important. A sample of 1000 students in 8 th to 10 th grades was randomly selected from 16 schools in Irbid, Jordan. A self-reported questionnaire including attitude related questions was used in a descriptive, cross-sectional study. Generally, the students expressed positive attitudes toward obesity; which means that their attitudes were consistent with societal norms in terms of health and social functioning (mean= 3.5, SD=0.39). Furthermore, the students expressed positive attitudes toward lifestyle; which means that their attitudes were consistent with healthy behaviors (mean=3.7, SD=0.58). However, boys had significantly more positive attitudes than girls (p =0.04). The prevalence of overweight and obesity was 23.8%, while obese and non-obese students had similar attitudes toward lifestyle and obesity. Finally, around 20% to 30% of students desired a prevention program out of school time shared with their families and friends and involves eating healthy food and getting more exercise. More efforts are needed to build effective obesity prevention programs that focus on eating healthy diet and getting more exercise considering gender differences.

    Full Text Available Manoj Sharma, Paul BranscumHealth Promotion and Education and Public Health Sciences, University of Cincinnati, Cincinnati, OH, USAAbstract: Overweight and obesity continue to be health concerns facing today’s adolescent population. Along with metabolic and physical problems associated with obesity, today’s obese adolescents also face many psychological issues such as high rates of depression, anxiety, and social discrimination. Obesity is commonly recognized as having many causes, such as genetic, lifestyle and environmental. There are four major modalities for management of overweight and obesity in adolescents: dietary management, increasing physical activity, pharmacological therapy, and bariatric surgery. The purpose of this study was to conduct a review of novel and emerging approaches for preventing and managing adolescent obesity. It was found that while not always the case, theory driven approaches are being better utilized in newer interventions especially by those directed toward prevention. New theories that are being used are the theories of reasoned action, planned behavior, intervention mapping, and social marketing. Schools are found to be the most common place for such interventions, which is appropriate since virtually all children attend some form of private or public school. Limitations found in many studies include the underuse of process evaluations, the low number of studies attempted, environmental or policy changes, and that not all studies used a similar control group for comparison.Keywords: adolescent overweight, adolescent obesity, interventions

    Studies from a number of countries have indicated an increased risk of obesity in adolescents with intellectual disability. Whether risk factors for adults with intellectual disability apply to adolescents however is uncertain. This study examines obesity in a community sample of adolescents with intellectual disability in Australia, and investigates risk factors associated with obesity and overweight. A cross-sectional survey and medical record review on 261 adolescents with intellectual disability attending special education facilities in South-East Queensland, Australia between January 2006 and September 2010 was conducted. Information on age, gender, weight, height, syndrome specific diagnoses, problematic behaviours, mobility, taking psychotropic or epileptic medication, and perceived household financial difficulties was collected. Body mass index (BMI) was calculated and participants categorised as normal/underweight, overweight or obese according to the International Obesity Taskforce definitions. Overall 22.5% (95% CI: 17.8-28.0%) of adolescents were obese, and 23.8% (95% CI: 19.0-29.4%) were overweight, a marked increase compared to Australian norms. Adolescents with Down syndrome were more likely to be obese than other participants (odds ratio=3.21; 95% CI: 1.41-7.30). No association was found with other risk factors examined. Prevalence of obesity and overweight were increased compared to general Australian adolescents. The only significant risk factor was the presence of Down syndrome. These findings reinforce the need for a health policy and practice response to obesity that is inclusive of individuals with intellectual disability.

    To test the hypothesis that individuals who are active but who decrease physical activity (PA) over time have a higher risk of becoming obese in young adulthood, when compared to individuals who are consistently active throughout childhood and adolescence. Iowa Bone Development Study cohort members (242 males and 251 females) participated in accelerometry assessments, dual-energy X-ray absorptiometry scans, and dietary questionnaire surveys at ages 5, 8, 11, 13, 15, 17, and 19 years. Group-based trajectory analyses identified distinct trajectory patterns of moderate- to vigorous-intensity PA (MVPA), percentage of body fat, and energy intake. A multivariable logistic regression model was fit to estimate the odds of "becoming obese" based on the MVPA trajectories, adjusted for mother's education, somatic maturation, and energy intake. Among males, 74.7% had a "normal" body fat pattern, 14.6% had a "becoming obese" pattern, and 10.7% had a "consistently obese" pattern, while among females, the percentages were 58.6%, 28.6%, and 12.8%, respectively. Participants who were active (≥45 min MVPA) as children but decreased MVPA with age were more likely to become obese, compared to consistently active participants (adjusted OR = 2.77; 95% CI = 1.16, 6.58). An active lifestyle throughout childhood and adolescence could prevent obesity development in young adulthood. © 2015 The Obesity Society.

    2005-01-01

    To study the relationship between plasma leptin, adiponectin, insulin, cortisol, aldosterone and BMI in simple obese females, leptin, adiponectin, insulin, cortisol and aldosterone were tested in 48 fat women with BMI ranging 23-24.9 kg/m 2 and another 40 with BMI≥ 25 kg/m 2 by radioimmunoassay and immunoradiometric assay. Besides, 42 healthy women(BMI ranging 18-22.9 kg/m 2 )were also tested as controls. Pearson's correlation and other statistic methods were used in data processing. The results showed that the levels of leptin, insulin, cortisol and aldosterone were linearily postively correlated with BMI in obesity groups, and were higher than those in controls remarkably (P<0.01). Meanwhile, the levels of adiponectin were linearily nagatively correlated with BMI in obesity groups. Our conclusion is that along with increase of BMI, the plasma levels of insulin and leptin increase in obese women, whereas the level of adiponectin decreases. The increasing levels of leptin, insulin, cortisol, aldosterone and decreasing level of adiponectin may be partly indicative of the etiology of diabetes, hyper- tension and nephrosis in obese females.

    Full Text Available Obesity and sleep disorders in adolescence are strongly associated, and they impact both on the health and on quality of life (QL in this age group. OBJECTIVE: To comparatively assess QL and sleep in obese and eutrophic adolescents, who are older than ten years of age. METHODS: Cross-sectional study including obese adolescents. This analysis was carried out between August 2009 and August 2010. The Control (eutrophic Group comprised schoolchildren recruited from State schools in the city of Americana, in São Paulo State, Brazil. Instruments applied included a standardized questionnaire, the Sleep Behavior Questionnaire (SBQ, and the Pediatric QL Inventory (PedsQL TM 4.0. RESULTS: The obese adolescents had poorer QL on physical (p<0.001, emotional (p=0.03, and social (p=0.002 functioning domains. A difference in mean psychosocial functioning was found between the groups (p=0.009 with obese subjects having a mean score of 69.5 (±16.0 and in eutrophic individuals of 76.2 (±16.7. A greater number of sleep problems was evident in the Obese Group (p=0.03. Conclusions: The obese adolescents had an impaired QL and a higher frequency of sleep problems compared to the eutrophic subjects.

    Obesity and cigarette smoking are two of the most frequent and preventable causes of disease and death in the United States; both are often established during youth. We hypothesized that obese, adolescent girls would be at higher risk for nicotine addiction in young adulthood, and that particular individual and social factors would mediate this association. Students surveyed in the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative school-based and in-home survey conducted in three waves, comprised the sample. More than 4,000 respondents were used for the multivariate linear and logistic regression analyses used to determine the association between obesity and level of nicotine addiction. Potential mediation effects of the association were also examined. Obesity doubled the risk of the highest level of nicotine addiction after controlling for demographic factors, parent and friend smoking, and baseline smoking (OR, 2.12; 95% CI, 1.22-3.68). Family smoking was the strongest predictor of nicotine addiction (OR, 4.72; 95% CI, 2.89-7.72). Grade point average was a partial mediator of this relationship (OR, .48; 95% CI, .32-.74). Obese, adolescent females are at increased risk for high-level nicotine addiction in young adulthood as compared with their nonobese peers. Grade point average partially mediates the association, and may represent a confluence of factors including increased absenteeism, social marginalization, biases, and lack of confidence in academic ability. Obese, adolescent females may require targeted interventions to address their risk of subsequent high-level nicotine addiction, especially if risk factors such as parental smoking and poor school performance are present.

    During the development of obesity, adipose tissue undergoes major expansion and remodeling, but the biological processes involved in this transition are not well understood. The objective of this study was to analyze global gene expression profiles of adipose tissue in dogs, fed a high-fat diet, during the transition from a lean to obese phenotype. Nine female beagles (4.09 ± 0.64 yr; 8.48 ± 0.35 kg) were randomized to ad libitum feeding or body weight maintenance. Subcutaneous adipose tissue biopsy, blood, and dual x-ray absorptiometry measurements were collected at 0, 4, 8, 12, and 24 wk of feeding. Serum was analyzed for glucose, insulin, fructosamine, triglycerides, free fatty acids, adiponectin, and leptin. Formalin-fixed adipose tissue was used for determination of adipocyte size. Adipose RNA samples were hybridized to Affymetrix Canine 2.0 microarrays. Statistical analysis, using repeated-measures ANOVA, showed ad libitum feeding increased (P obesity development.

    Overweight children are growing problem as in the pediatric, as well in the diabetic population. The aim of the study was to research the percentage of overweight and obesity in a group of adolescents with type 1 diabetes, and to analyzethe lipid parameters, as well risk factors of these abnormalities. The study group consist of 60 type 1 diabetic adolescents (including 32 girls, 53.3%), aged above 12 years (mean age for girls 14.6+/-0,3years, boys 15.6+/-0.4 years) with diabetes duration (girls 5.7+-0.6 years, boys 4.4+/-0.8 years). Statistical analysis was performed using Statistica v 9.0 and SPSS v20. The study revealed that boys with type 1 diabetes are significantly higher than healthy population, with weight, waist circumference and BMI comparable to the healthy counterparts. However, diabetic girls are more likely to be overweight and have bigger waist circumference, and higher BMI than the healthy population. Overweight were 12 adolescents (20%) using BMI ≥1SD criterion, and 10 (16%) using waist circumference as obesity parameter. Logistic regression revealed that the most important factors for obesity and abdominal obesity are female gender (OR=2.43 and OR=4.56for obesity and abdominal, respectively), diabetes duration above 5 years (respectively OR=1.96 and OR=3.27) and poor metabolic control (respectively OR=1.74 and OR=2.89). The most important risk factor for obesity in adolescents with type 1 diabetes is female gender. Lipids profile is closely dependent on metabolic control and mass excess. Diabetes duration, metabolic control and lipids profile are significant risk factors for overweight and abdominal obesity. © Polish Society for Pediatric Endocrinology and Diabetology.

    Celiac disease (CD) usually presents with diarrhea and growth retardation in childhood. Obesity is one of the paradoxical conditions in children with CD. We present two adolescents with CD and obesity. One of these patients was diagnosed as CD with malnutrition. His body weight had returned to normal after a gluten-free diet, and after stopping the diet, he had become obese. The second patient was an obese adolescent presenting with dyspeptic symptoms who was diagnosed as CD. Although rare, pediatricians should remember that obesity might be seen in CD before or after the diagnosis.

    Full Text Available Vigorous aerobic exercise may improve aerobic capacity (VO2max and cardiometabolic profiles in adolescents with obesity, independent of changes to weight. Our aim was to assess changes in estimated VO2max in obese adolescents following a 6-week exercise program of varying intensities. Adolescents with obesity were recruited from an American mid-west children’s hospital and randomized into moderate exercise (MOD or high intensity interval exercise (HIIE groups for a 6-week exercise intervention, consisting of cycle ergometry for 40 minutes, 3 days per week. Heart rate was measured every two minutes during each exercise session.  Estimated VO2max measured via Åstrand cycle test, body composition, and physical activity (PA enjoyment evaluated via questionnaire were assessed pre/post-intervention. Twenty-seven adolescents (age 14.7±1.5; 17 female, 10 male completed the intervention. Estimated VO2max increased only in the HIIE group (20.0±5.7 to 22.7±6.5 ml/kg/min, p=0.015. The HIIE group also demonstrated increased PA enjoyment, which was correlated with average heart rate achieved during the intervention (r=0.55; p=0.043. Six weeks of HIIE elicited improvements to estimated VO2max in adolescents with obesity. Furthermore, those exercising at higher heart rates demonstrated greater PA enjoyment, implicating enjoyment as an important determinant of VO2max, specifically following higher intensity activities.

Updated definitions of elevated BP and hypertension in adolescents are now similar to definitions of BP status in adults. For adolescents ≥13 years of age, elevated BP is 120 to 129/<80 mm Hg. Hypertension, stage 1, is ≥130 to 139/80 to 89 mm Hg, and hypertension, stage 2, is ≥140/90 mm Hg. BP measurements over separate clinic visits are necessary to verify the diagnosis of elevated BP or hypertension. Ambulatory BP monitoring, when available, provides confirmatory data on BP status. Causal mechanisms for obesity associated hypertension include increased sympathetic nervous system activity, increased renal sodium retention secondary to insulin resistance/hyperinsulinemia, and obesity mediated inflammation. The primary treatment for obesity associated hypertension is weight reduction with lifestyle changes in diet and physical activity. Although difficult to achieve, even modest weight reduction can be beneficial. The diet should be rich in fruits, vegetables, fiber, and low-fat dairy with reduction in salt intake. When lifestyle changes are insufficient to achieve BP control, pharmacologic therapy is indicated to achieve a goal BP of <130/80 mm Hg or <90th percentile, whichever is lower. Regular BP monitoring is necessary for ongoing management of obesity associated hypertension in adolescents. Keywords: adolescents, obesity, blood pressure, hypertension

    Objective This study aimed to analyse the psychological conditions and behaviour of a group of Chinese children and adolescents with obesity, and to develop an intervention for these young patients. Methods A group of 72 patients aged from 4 to 15 years were recruited from an obesity clinic. Patients, or the parents of children younger than 12 years, filled out a series of self-report questionnaires, and the responses were recorded and analysed. Results The 72 children and adolescents with obesity had a mean age of 9.14 ± 2.18 years. The body mass index-z scores of children with obesity showed a significant positive correlation with the level of impulsive behaviour, motivational impulses, and cognitive instability (inattention). Children with obesity quickly responded with extreme emotions, and these responses were positively correlated with the degree of obesity (slight, intermediate, or severe obesity). Conclusion Children and adolescents being treated for obesity have many underlying psychological problems, including emotional instability and impulsivity, and are prone to extreme emotional-psychological problems. These difficulties are positively correlated with the degree of obesity. Therefore, clinical treatment of these problems requires not only use of medication, improved nutrition, and healthy exercise, but also addressing underlying psychologic problems.

    Independent associations of physical activity (PA) and sedentary behavior (SB) with obesity are well documented. However, little is known about the combined associations of these behaviors with obesity in adolescents. The present study examines the prevalence of concurrent levels of PA and SB, and their associations with obesity among US adolescents. Data from a total of 12 081 adolescents who participated in the Youth Risk Behaviors Survey during 2012-2013 were analyzed. A latent class analysis was performed to identify latent subgroups with varying combined levels of subjectively measured PA and screen-based SB. Follow-up analysis examined the changes in the likelihood of being obese as determined by the Center for Disease Control and Prevention Growth Chart between latent subgroups. Four latent subgroups with varying combined levels of PA and SB were identified across gender. The likelihood of being obese was significantly greater for the subgroups featuring either or both Low PA or High SB when compared with High PA/Low SB across genders (odds ratio [OR] ranges, 2.1-2.7 for males and 9.6-23.5 for females). Low PA/High SB showed the greater likelihood of being obese compared to subgroups featuring either or both High PA and Low SB (OR ranges, 2.2-23.5) for female adolescents only. The findings imply that promoting sufficient levels of PA while reducing SB should be encouraged in order to reduce obesity risk among adolescents, particularly for males. The risk of obesity for female adolescents can be reduced by engaging in either high levels of PA or low levels of SB.

    The aim of this study was to describe the prevalence of biochemical markers and associate with obesity in Brazilian adolescents enrolled in public schools in a rural area. The sample consisted of 199 adolescents between 10 to 14 years old from Piracicaba, Brazil. The obesity was measured by body mass index (BMI and according to the World Health Organization curves. We collected blood for biochemical markers analysis (total cholesterol, high density lipoprotein, low density lipoprotein, triacylglycerol, insulin and glycemia. Mann Whitney test was used to compare continuous variables between sexes. Chi-square test was used to compare proportions. To investigate the association between the independent variables and biochemical markers a multiple logistic regression model was performed. Among 199 adolescents, 23.1% was obese and 65.8% were insufficiently active. A high prevalence of dyslipidemia (71.4% was observed, whereas the low levels of high density lipoprotein (40.7% were the most prevalent. An association between obesity and undesirable values for high density lipoprotein, triacylglycerol and insulin resistance was found. Obese adolescents were less likely to present a desirable value for high density lipoprotein. It is understood that obesity is detrimental to metabolic profile and should be prevented and treated even in adolescence.

    To assess the impact of obesity on carotid intima media thickness and left ventricular (LV) mass in obese adolescents. The study included 52 obese adolescents (mean age 14.16+/-2.64 years) and 52 healthy adolescents who served as a control group (mean age 12+/-2.3 years), who were attended the outpatient clinic at Suez Canal University Hospital, Ismailia, Egypt. The study population was submitted for medical history, clinical examination, laboratory investigations (fasting blood sugar and lipid profile), and echocardiographic examination of LV mass and dimensions. Assessment of carotid intima-media thickness was carried out by using carotid duplex. All children had normal LV function. Obese adolescents had a significant increase in total cholesterol, triglyceride, LDL-C, and low HDL-C compared to the control group. Also, there was a significant increase in blood pressure, carotid intima media thickness, LV mass, and LV mass index. There was a significant correlation between BMI and dyslipidemia, blood pressure, carotid intima/media thickness, LV mass, and posterior wall thickness. Carotid intima-media thickness had a significant correlation with increased LDL-C and low HDL-C, blood pressure, LV mass, and posterior wall thickness. Obesity in childhood and adolescents is associated with subclinical atherosclerosis. Although obese children had no LV dysfunction, yet there are LV structure changes.

    The potential for peers to influence obesity risk behavior increases in adolescence, yet there are knowledge gaps of how behaviors are modified in response to peers over time. This study examined how personal friendship network characteristics were associated with obesity-related behaviors from late childhood to early adolescence. Two waves of friendship, physical activity, screen time, and dietary recall data were collected from 11- to 13-year-old students (99% retention) in Australia (n = 308) over a five- to eight-month period. Regression models identified friendship network characteristics that predicted later health behaviors which varied by gender and behavior type, such as the number of friends positively associated with physical activity intensity (males) and screen time (females). The need for considering context to influence behavior change is discussed. © 2018 Society for Research on Adolescence.

    Full Text Available Abstract Background The purpose of this study was to determine the prevalence of overweight and obesity and to examine the effects of actual weight status, perceived weight status and body satisfaction on self-esteem and depression in a high school population in Turkey. Methods A cross-sectional survey of 2101 tenth-grade Turkish adolescents aged 15–18 was conducted. Body mass index (BMI was calculated using weight and height measures. The overweight and obesity were based on the age- and gender-spesific BMI cut-off points of the International Obesity Task Force values. Self-esteem was measured using the Rosenberg Self-Esteem Scale, and depression was measured using Children's Depression Inventory. Logistic regression analysis was used to examine relationships among the variables. Results Based on BMI cut-off points, 9.0% of the students were overweight and 1.1% were obese. Logistic regression analysis indicated that (1 being male and being from a higher socio-economical level were important in the prediction of overweight based on BMI; (2 being female and being from a higher socio-economical level were important in the prediction of perceived overweight; (3 being female was important in the prediction of body dissatisfaction; (4 body dissatisfaction was related to low self-esteem and depression, perceived overweight was related only to low self-esteem but actual overweight was not related to low self-esteem and depression in adolescents. Conclusion The results of this study suggest that school-based adolescents in urban Turkey have a lower risk of overweight and obesity than adolescents in developed countries. The findings of this study suggest that psychological well-being of adolescents is more related to body satisfaction than actual and perceived weight status is.

    Inflammation, oxidative stress and dysregulation of adipokines are thought to be pathophysiological mechanisms linking obesity to the development of insulin resistance and atherosclerosis. In adults, bariatric surgery reduces inflammation and oxidative stress, and beneficially changes the levels of several adipokines, but little is known about the postsurgical changes among adolescents. In two separate longitudinal cohorts we evaluated change from baseline of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), monocyte chemo-attractant protein-1 (MCP-1), oxidized low-density lipoprotein cholesterol (oxLDL), adiponectin, leptin and resistin up to 12 months following elective laparoscopic Roux-en-Y gastric bypass (RYGB) or vertical sleeve gastrectomy (VSG) surgery in adolescents with severe obesity. In cohort 1, which consisted of 39 adolescents (mean age 16.5±1.6 years; 29 females) undergoing either RYGB or VSG, IL-6 (baseline: 2.3±3.4 pg ml(-1) vs 12 months: 0.8±0.6 pg ml(-1), Padolescents (mean age 16.5±1.6 years; 10 females) undergoing RYGB, results were similar: IL-6 (baseline: 1.7±0.9 pg ml(-1) vs 12 months: 0.4±0.9 pg ml(-1), PBariatric surgery produced robust improvements in markers of inflammation, oxidative stress and several adipokines among adolescents with severe obesity, suggesting potential reductions in risk for type 2 diabetes and cardiovascular disease.

    This meta-analysis aimed to evaluate the association between childhood and adolescent obesity and depression. We systematically searched PubMed, PsycInfo, EMBASE and Science Direct for studies that compared prevalence of depression and depressive symptoms in normal weight and obese children and adolescents. Observational studies were included if they reported body mass index and assessed depression by validated instruments or diagnostic interviews. Quality assessment was performed using the Newcastle-Ottawa scale. We used the random-effect model to calculate the pooled odds ratios, standard mean differences (SMDs) and subgroup analysis. Findings for a total of 51,272 participants were pooled across 18 studies and examined. Our analyses demonstrated a positive association between childhood and adolescent obesity and depression (pooled odds ratio = 1.34, 95% confidence interval [CI]: 1.1-1.64, p = 0.005) and more severe depressive symptoms (SMD = 0.23, 95% CI: 0.025-0.44, p = 0.028) in the obese groups. Overweight subjects were not more likely to have either depression (pooled odds ratio = 1.16, 95% CI: 0.93-1.44, p = 0.19) or depressive symptoms (SMD = 0, 95% CI: -0.101 to 0.102, p = 0.997).

    2013-01-01

    Background: The recommended anthropometric methods to assess the weight status include body mass index (BMI), skinfold thickness, and waist circumference. However, these methods have advantages and disadvantages regarding the classification of overweight and obesity in adolescents. Aims: The study was to analyze the correlation between the measurements of BMI, skinfold thickness and waist circumference to assess overweight and obesity in Portuguese adolescents. Materials and Methods: A sample of 966 students of Portugal was used. Of them, 437 (45.2%) were males and 529 (54.8%) were females aged between 10 and 16 years. The evaluations included BMI calculation, skinfold thickness, and waist circumference measurements. Results: This study revealed a high prevalence of overweight and obesity with values ranging from 31.6%, 61.4%, and 41.1% according to the measurement of BMI, skinfold thickness, and waist circumference, respectively. The results found a high level of correlation between BMI and skinfold thickness (P < 0.001, r = 0.712), between BMI and waist circumference (P < 0.001, r = 0.884), and waist circumference and skinfold thickness (P < 0.001, r = 0.701). Conclusions: This study revealed a high prevalence of overweight and obesity in Portuguese adolescents using three different anthropometric methods, where the BMI showed the lowest values of prevalence of overweight and obesity and the skinfold thickness showed the highest values. The three anthropometric methods were highly correlated. PMID:24404544

    Overweight and obesity continue to be health concerns facing today's adolescent population. Along with metabolic and physical problems associated with obesity, today's obese adolescents also face many psychological issues such as high rates of depression, anxiety, and social discrimination. Obesity is commonly recognized as having many causes, such as genetic, lifestyle and environmental. There are four major modalities for management of overweight and obesity in adolescents: dietary management, increasing physical activity, pharmacological therapy, and bariatric surgery. The purpose of this study was to conduct a review of novel and emerging approaches for preventing and managing adolescent obesity. It was found that while not always the case, theory driven approaches are being better utilized in newer interventions especially by those directed toward prevention. New theories that are being used are the theories of reasoned action, planned behavior, intervention mapping, and social marketing. Schools are found to be the most common place for such interventions, which is appropriate since virtually all children attend some form of private or public school. Limitations found in many studies include the underuse of process evaluations, the low number of studies attempted, environmental or policy changes, and that not all studies used a similar control group for comparison.

    The study was done to assess the magnitude of problems of metabolic syndrome among obese adolescents. It was a cross-sectional study done from January 2013 to June 2014 in paediatric endocrine outpatient department in BIRDEM General Hospital, Dhaka, Bangladesh. Total 172 adolescents having exogenous obesity aged 10-18 years were included. Impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and type 2 diabetes mellitus (DM) were defined as per WHO criteria.The adolescents having Body Mass Index (BMI) ≥95th centile were classified as obese.Waist circumference was measured at the level midway between the lower rib margin & the iliac crest, at the level of umbilicus with the person breathing out gently in centimeter. Hip circumference was measured at the maximum width over the buttocks at the level of the greater trochanters in centimeter. Among 172 obese adolescents, metabolic syndrome was found in 66 patients (38.4%). The commonest metabolic abnormality among those having metabolic syndrome was low HDL level (77.3%) followed by high triglyceride level(71.2%). Glucose intolerance (IFG and/or IGT) was found in 16.7%, Type 2 DM in 10.6%, systolic hypertension in 10.7% and diastolic hypertension in 12.1%. Triglyceride (p = 0.042) and Cholesterol level (p = 0.016) were significantly higher and HDL-cholesterol level (p = 0.000) was significantly lower among obese adolescents having metabolic syndrome. Less physical activity (p = 0.04) was significantly related to the development of metabolic syndrome. On logistic regression analysis male sex, family history of obesity and low HDL-cholesterol correlated to metabolic syndrome. The High rate of metabolic syndrome among obese adolescents is alarming.

    Adolescent obesity and hypertension are global public health issues. The burden of adolescent obesity and hypertension in Peru is unclear. The aim of this study was to determine the prevalence of obesity and hypertension and their relationship among school-attending adolescents and to assess the need for health-promoting school programs in the study area. A cross-sectional school-based survey was conducted in a randomly selected sample of 952 secondary school adolescents from 11 schools in Lima or Callao, Peru, in 2014. Weight, height, and blood pressure (BP) were measured and categorized. Obesity was defined as ≥ 95(th) percentile in body mass index (BMI) for age and sex. Hypertension was defined as average systolic blood pressure and/or diastolic blood pressure ≥95(th) percentile in BP for sex, age, and height. Chi-square test and univariate logistic regressions were used at a 5% significance level to determine the relationship between BMI and BP category. The mean age of subjects was 14.6 years; 46.4% were boys and 53.6% were girls. The prevalence of overweight and obesity was 20.2% and 9.5% overall, 17.4% and 11.1% for boys, and 22.5% and 8.0% for girls, respectively. The prevalence of hypertension was 26.7% overall, 34.8% for boys, and 19.6% for girls. In both sexes, BMI was strongly associated with BP (p Overweight and obesity are strongly associated with BP status among adolescents. Health-promoting school programs may reduce the burdens of obesity and hypertension among school-going adolescents.

    Wasserman, Halley; Inge, Thomas H

    2014-09-01

    Extreme obesity is defined by the Centers for Disease Control and Prevention as a body mass index (BMI) higher than 120% of the 95th percentile for age. Four to six percent of American youths fall into this subcategory and are at increased risk for developing comorbidities, including hypertension, dyslipidemia, nonalcoholic fatty liver disease, insulin resistance, sleep apnea, and bone and joint problems. Many studies have shown that nonsurgical treatment programs do not provide significant long-term improvements in BMI in adolescents with severe obesity. In adults, bariatric (weight loss) surgery has been shown to dramatically reduce BMI and to reverse or prevent many complications of obesity; thus, bariatric surgery is being used in an attempt to reverse clinically severe obesity in adolescents. This review highlights the indications for bariatric surgery in adolescents and outlines practice guidelines for adolescent surgical weight loss programs. The authors summarize available data on the effects of adolescent weight loss surgery on metabolic comorbidities and highlight the important acute and long-term complications that must be monitored by their general pediatricians. After reading this article, the general pediatrician should be able to identify adolescents who may be candidates for weight loss surgery and have the knowledge to assist in their postoperative medical management.

    Full Text Available The aim of this paper is to draw attention to obesity in adolescence and its potential risks and put forward its consequences in terms of public health as well as offer solutions. Today, obesity has become one of the most frequent chronic diseases of childhood. The tendency to obesity is at an alarming level and the annual increase in this age group is gradually rising. In the 2003 report of the International Obesity Commission, it was stated that one out of ten children aged between 5-17 worldwide was overweight or obese. In addition to social and psychological problems resulting from obesity, it is known to be closely related with very serious diseases such as hypertension, cardiovascular diseases, type 2 diabetes and metabolic syndrome. It is also known that obesity shortens life expectancy and that the process starts in the childhood period of many obese adults. Struggling with obesity actually means struggling with many other diseases. It is also of major significance for the future of our country to struggle with especially childhood obesity. In terms of public health, it is of primary importance to detect, avoid and cure obesity in this period. [TAF Prev Med Bull 2011; 10(2.000: 223-230

To support young obese patients adequately, it is necessary to assess their individual physical and motor abilities, taking the degree of obesity into account. A total of 5 924 children and adolescents (mean age: 12.7±2.5 years, range 6.0-18.0 years, 3 195 girls) were examined in a standardised multicentre evaluation survey (APV). Fitness parameters were correlated with age- and gender-specific BMI-SDS (Standard Deviation Score) Methods: Anthropometric data were collected and patients performed the modified Munich fitness test (mMFT: maximal power, coordination, trunk flexibility) and a 6-min walk-test (aerobic endurance capacity). 33% of patients were extremely obese (BMI>99.5th percentile). Mean BMI-SDS was + 2.32±0.53 (♀-Δ=+ 0.06; pmotor performance, especially maximal power (r=- 0,134), and particularly aerobic endurance capacity (r=- 0,214; all pMotor performance was significantly below average (n=27 473, 6-18 years), especially among extremely obese patients. Performance in all motor tasks was lower in girls compared to boys, except for trunk flexibility (pmotor performance. Extremely obese patients and obese girls showed the most pronounced motor deficits. These results emphasize the importance of standardized evaluation of individual motor performance in children and adolescents with obesity. © Georg Thieme Verlag KG Stuttgart · New York.

Treatment of morbidly obese adolescents should include a multidisciplinary team to address medical comorbidities, diet, physical activity, mental health, and behavior modification. Anti-obesity pharmacologic agents have a limited role in the treatment of adolescents because of concerns with side effects, safety, and efficacy. Orlistat (GlaxoSmithKline, Moon Township, PA is the only approved medication for weight-loss in adolescents. However, it is associated with gastrointestinal side effects and its long-term efficacy is unknown. Bariatric surgery is the most effective therapy to treat morbid obesity. However, adolescents must meet rigorous criteria and have appropriate cognitive, psychological, and social clearance before being considered for surgical intervention. Gastric bypass remains the gold standard bariatric operation. The adjustable gastric band is not FDA-approved for use in patients under 18 years of age. Sleeve gastrectomy is a promising procedure for adolescents because it avoids an intestinal bypass and the implantation of a foreign body. Prospective longitudinal assessment of bariatric surgery procedures is required to determine long-term outcomes. In this manuscript, we review the treatment options, efficacy, and impact on quality of life for morbidly obese adolescents.Keywords: bariatric surgery, morbid obesity, weight loss, adolescent

    Obesity results from a complex combination of factors that act at many stages throughout a person's life. Therefore, examining childhood nutrition and obesity from a developmental perspective is warranted. A developmental perspective recognizes the cumulative effects of factors that contribute to eating behavior and obesity, including biological and socioenvironmental factors that are relevant at different stages of development. A developmental perspective considers family, school, and community context. During gestation, risk factors for obesity include maternal diet, overweight, and smoking. In early childhood, feeding practices, taste acquisition, and eating in the absence of hunger must be considered. As children become more independent during middle childhood and adolescence, school nutrition, food marketing, and social networks become focal points for obesity prevention or intervention. Combining a multilevel approach with a developmental perspective can inform more effective and sustainable strategies for obesity prevention.

    Full Text Available Background. The State of Kuwait has a growing obesity epidemic in both genders and all age groups; however, obesity rates in the young seem to be rising. Methods. We conducted a cross-sectional survey in 169 Kuwaiti female adolescents attending both private and public schools spanning the six governorates in the State of Kuwait in order to explore female adolescents’ self-image, body dissatisfaction, type of school (private versus public, TV viewing, and computer games and their relationship to body mass index. Results. Approximately half the students classified as obese perceived their body image to lie in the normal range. Females in the obese category were the most dissatisfied with their body image, followed by those in the overweight category. Eating behavior, level of physical activity, school type, television viewing, computer/video usage, and desired BMI were not significantly associated with level of obesity. Conclusion. This study was one of the few studies to assess adolescent females’ body image dissatisfaction in relation to obesity in the State of Kuwait. The results suggest that including body image dissatisfaction awareness into obesity prevention programs would be of value.

    African American adolescents experience higher rates of obesity and have an increased risk of obesity-related diseases than do White American adolescents. Despite culturally sensitive obesity preventive interventions, obesity rates are increasing within the African American adolescent population. Current obesity interventions do not usually address the heterogeneity (e.g., socioeconomic status [SES], gender, and residential status differences) within the African American adolescent community that can affect the efficacy of these interventions. To examine the gender, SES, and residential status differences related to obesity and weight behaviors in African American adolescents. A descriptive correlational study was conducted with 15- to 17-year-old African American adolescents (n = 145) from community clinics, youth organizations, churches, and social networks in metropolitan and inner-city Detroit. Data were collected through use of survey methods and analyzed with use of descriptive statistics, independent sample t tests, and multiple regression equations. Female adolescents consumed foods higher in fat and calories (t = -2.36, p = .019) and had more body fat (t = -9.37, p = .000) than did males. Adolescents of lower SES consumed food higher in fat and calories (t = -2.23, p = .027) and had higher body mass (t = -2.57, p = .011) than did adolescents of higher SES. Inner-city African American adolescents had higher levels of physical activity (t = -2.39, p = .018) and higher body mass (t = 2.24, p = .027) than did suburban African American adolescent counterparts. Gender, SES, and residential status were statistically significant predictors of eating behaviors, physical activity, body mass index, and body fat. The initial findings from the study will assist in better understanding the obesity epidemic that affects African American adolescents in disparate proportions. Further examination of the study variables is essential to serve as a basis for

    To estimate overweight and obesity prevalence trends in Slovenian adolescents entering secondary schools in the years 2004, 2009 and 2014 and differences in the prevalence between different types of secondary schools. Data from 17,538 adolescents entering secondary schools (mean age ± standard deviation 15.4 ± 0.5 years) collected during obligatory medical examination in years 2004, 2009 and 2014 was analyzed. Overweight and obesity were defined using International Obesity Task Force criteria. In 2004-2009 overweight and obesity prevalence increased, especially in males and stabilized thereafter (2009-2014) in both genders. It was significantly higher (p schools (2009; 28.7 vs. 16.8% overweight females and 31.6 vs. 22.3% overweight males; 2014: 29.7 vs. 17.9% overweight females and 33.6 vs. 20.4% overweight males). Overweight and obesity prevalence in Slovenian adolescents entering secondary schools stabilized recently. Adolescents attending secondary vocational and technical/professional schools are at an increased risk of overweight and obesity. © 2016 The Author(s) Published by S. Karger GmbH, Freiburg.

    Obesity is the most frequent nutritional disorder in childhood and adolescence. The rise in its prevalence and severity has underlined the numerous and significant obesity-related metabolic disorders. Altered glucose metabolism, manifested as impaired glucose tolerance, appears early in severely obese children and adolescents. Obese young people with glucose intolerance are characterized by marked peripheral insulin resistance and relative beta-cell failure. Lipid deposition in muscle and the visceral compartment, and not only obesity per se, is related to increased peripheral insulin resistance, the triggering factor of the metabolic syndrome. Other elements of the metabolic syndrome, such as dyslipidaemia, and hypertension, are already present in obese youngsters and worsen with the degree of obesity. The long-term impact of obesity-related insulin resistance on cardiovascular morbidity in these patients is expected to emerge as these youngsters become young adults.

    2013-01-01

    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.

    2014-08-01

    This study examined longitudinal associations of prenatal exposures as well as childhood familial experiences with obesity status from ages 10 to 18. Hierarchical generalized linear modeling (HGLM) was applied to examine 5,156 adolescents from the child sample of the 1979 National Longitudinal Survey of Youth (NLSY79). Higher maternal weight, maternal smoking during pregnancy, lower maternal education, and lack of infant breastfeeding were contributors to elevated adolescent obesity risk in early adolescence. However, maternal age, high birth weight of child, and maternal annual income exhibited long-lasting impact on obesity risk over time throughout adolescence. Additionally, childhood familial experiences were significantly related to risk of adolescent obesity. Appropriate use of family rules in the home and parental engagement in children's daily activities lowered adolescent obesity risk, but excessive television viewing heightened adolescent obesity risk. Implementation of consistent family rules and parental engagement may benefit adolescents at risk for obesity.

  8. Harsh Parenting and Food Insecurity in Adolescence: The Association With Emerging Adult Obesity.

    As the first study of its kind, the overall purpose of this article was to examine the relationships and interactions between harsh parenting (HP) and food insecurity (FI) in adolescence on the development of overweight/obesity (OW/OB) in emerging adulthood. Data came from the Iowa Youth and Families Project, a longitudinal study of 451 adolescent youth and their families that began in 1989 in the rural Midwest. Adolescents were aged 13 years at the initial assessment, and weight status in emerging adulthood was measured 10 years later at age 23. Experiencing HP in adolescence predicted greater odds of OW/OB at 23 years old. Higher body mass indexes of the adolescent and his or her father in adolescence also increased the odds of being OW/OB at 23 years. Having parents with higher levels of education lowered the odds of being OW/OB in emerging adulthood. Finally, females who experienced high levels of FI and HP in adolescence had higher odds of OW/OB at 23 years in comparison to males. HP, in combination with FI in adolescence, predicted OW/OB for females in emerging adulthood but not for males. This study contributes to an understanding of the interplay between multiple influences in adolescence: namely, parenting and economic influences. Assessing antecedents to OW/OB in emerging adulthood via multiple pathways provides a more complex understanding of how and why adolescents turn into OW/OB adults.

    2015-08-01

    This update explores the current management options for adolescent obesity with a specific focus on bariatric surgery. Research has highlighted the serious health complications associated with adolescent obesity and thus emphasized the need for effective interventions. With the increasing severity of obesity seen in younger populations, coupled with the modest effects of most behavioral and even pharmacologic interventions, there has been increased interest in, and attention on, bariatric surgery in younger populations. Recent adult-focused guidelines regarding the perioperative nutritional, metabolic, and nonsurgical support of the bariatric surgery patient outline the importance of careful patient selection, in addition to close monitoring, with a particular focus on preventing nutritional deficiencies. Several recent publications have focused on issues specific to bariatric surgery in the adolescent patient including the relationship between a patient's physical and emotional maturity and timing of surgery. Adolescent obesity is prevalent with increasing severity and long-term health implications. To date nonsurgical interventions have had modest effects. Bariatric surgery is becoming more common and has been shown to be well tolerated and effective in adolescents, but requires careful preoperative screening and postoperative monitoring.

    Full Text Available Background and objectives: Obesity and overweight is a growing pandemic affecting millions of adolescents in developed as well as developing countries. Obesity is associated with the onset of major chronic diseases leading to complications and also psychosocial problems in adolescents. The greater concern is that the risks of obesity during childhood will persist into adolescence and adulthood. The objectives of the study were to assess the prevalence of being overweight and obesity and to study the associated risk factors. Materials and Methods: 1900 adolescents in the age group of 10-19 years were included in the study. A predesigned and pretested questionnaire which included the variables such as going to school by bus or cycle, eating habits, playing video/computer games or outdoor games and sibling count were recorded. Body weight and height were recorded in subjects for calculating body mass index (BMI. International Obesity Task Force (IOTF classification was used for the estimation of being overweight and obese. Results: The mean age of the study subjects was 14.84 years (SD = 2.81. Mean weight increased from 34.7 to 55.09 kg from the age group 10-13 to 17-19 years. Mean height also increased from 1.34 to 1.57 m from the age group 10-13 to 17-19 years. Similarly, the mean body mass index was 19.23 at 10-13 years, followed by 21.11 at 14-16 years and 22.46 at 17-19 years. On binary logistic regression analysis, female gender, bus as a mode of transport, not playing games, and single sibling were found to have independent association with prevalence of being overweight.

    In a cross-sectional study design we test the hypothesis of whether obesity in adolescence is associated with periodontal risk indicators or disease. Obese adolescents (n=52) and normal weight subjects (n=52) with a mean age of 14.5 years were clinically examined with respect to dental plaque, gingival inflammation, periodontal pockets and incipient alveolar bone loss. The subjects answered a questionnaire concerning medical conditions, oral hygiene habits, smoking habits and sociodemographic background. Body mass index (BMI) was calculated and adjusted for age and gender (BMI-SDS). Samples of gingival crevicular fluid (GCF) were analyzed for the levels of adiponectin, plasminogen activator inhibitor-1 (PAI-1), interleukin-1β (IL-β), interleukin-8 (IL-8) and tumor necrosis factor α (TNF-α). Obese subjects exhibited more gingival inflammation (Pperiodontal pockets (>4 mm) (Pperiodontal pockets. The study demonstrates an association between obesity and periodontal risk indicators in adolescents that in the long term may lead to oral morbidity. This result further strengthens obesity's negative effect on teenagers' periodontal health and highlights the importance of a close collaboration between dentists and pediatricians in the prevention and treatment of obesity.

    To study bone density as a concomitant factor for obesity in post-pubertal adolescents, controlling for other variables that may interfere in such a relation. Study comprising 83 overweight and obese adolescents (BMI > or = P85) and 89 non obese ones (P5 obesity followed by multivariate analysis (logistic regression) according to a hierarchical conceptual model. The prevalence of bone density above the median was twice more frequent among cases (69.3%) than among controls (32.1%). In the bivariate analysis such prevalence resulted in an odds ratio (OR) of 4.78. The logistic regression model showed that the association between obesity and mineral density is yet more intense with an OR of 6.65 after the control of variables related to sedentary lifestyle and intake of milk and dairy products. Obese and overweight adolescents in the final stages of sexual maturity presented higher bone mineral density in relation to their normal-weight counterparts; however, cohort studies will be necessary to evaluate the influence of such characteristic on bone resistance in adulthood and, consequently, on the incidence of osteopenia and osteoporosis at older ages.

    To evaluate the association between adverse family experiences (AFEs) during childhood and adolescent obesity and to determine populations at highest risk for AFEs. A cross-sectional analysis was performed of the 2011-2012 National Survey of Children's Health, including children aged 10-17 years. Weighted estimates of 31,258,575 children were based on interviews with 42,239 caregivers. Caregiver reports of nine psychosocial risk factors measured AFEs during childhood. Adolescent overweight and obesity were derived by caregiver-reported child height and weight. Nearly one-third (30.5%) of children had experienced ≥2 AFEs, with geographic variation by state. The prevalence of obesity among children experiencing ≥2 AFEs was 20.4%, when compared with 12.5% among children with 0 AFEs. Adjusted survey regression models were controlled for child, parent, household, and neighborhood characteristics. Children with ≥2 AFEs in childhood were more likely to have obesity (AOR = 1.8; 95% CI = 1.47-2.17; P Adolescents in this national sample who were exposed to greater numbers of AFEs in childhood also had higher rates of overweight and obesity. Geographic variation and differential associations based on race/ethnicity identified children at greatest risk. © 2016 The Obesity Society.

    Baur, Louise A; Hazelton, Briony; Shrewsbury, Vanessa A

    2011-10-04

    The increased prevalence of obesity in childhood and adolescence highlights the need for effective treatment approaches. Initial assessments of these patients should include taking a careful history (investigating comorbidities, family history and potentially modifiable behaviors) and physical examination with BMI plotted on a BMI-for-age chart. The degree of investigation is dependent on the patient's age and severity of obesity, the findings on history and physical examination, and associated familial risk factors. There are several broad principles of conventional management: management of comorbidities; family involvement; taking a developmentally appropriate approach; the use of a range of behavior change techniques; long-term dietary change; increased physical activity; and decreased sedentary behaviors. Orlistat can be useful as an adjunct to lifestyle changes in severely obese adolescents and metformin can be used in older children and adolescents with clinical insulin resistance. Bariatric surgery should be considered in those who are severely obese, with recognition of the need for management in centers with multidisciplinary weight management teams and for surgery to be performed in tertiary institutions experienced in bariatric surgery. Finally, given the high prevalence and chronic nature of obesity, coordinated models of care for health-service delivery for the management of pediatric obesity are needed.

    Sema Sal ALTAN

    Full Text Available ABSTRACT Objective To examine the effect of parental feeding styles and children’s self-efficacy and social anxiety on adolescent obesity. Methods The samples of this descriptive and cross-sectional study were collected by using a simple sampling method. The study group was composed of 649 Turkish secondary schools students and their parents. Three secondary schools were selected from both rural and urban areas of the province. Data of the study were collected with the child-parent socio-demographic data collection form, the parenting feeding style questionnaire, the middle school self-efficacy scale and the social anxiety scale for the adolescent. To analyze the data of the study, we used percentages, mean, correlation, and regression analysis. Results The average age of the students was 11.58+1.21 years and percentages of female students 55.0%. The factors that significantly affect male adolescent obesity were fear of social situations in general, interpersonal relations, preventive healthcare self-efficacy, and strict dietary control, respectively. The factors affect male adolescent obesity at the rate of 35.0%. The factors that significantly affect female adolescent obesity were fear of social situations in general, preventive healthcare self-efficacy, emotional feeding, social evasion and distress in new situations, and tolerant dietary control, respectively. These factors affect female adolescent obesity at the rate of 32.8%. Conclusion It is indicated that the obesity of children is affected by self-efficacy levels, social anxiety, and the parental feeding style.

    Full Text Available This study aims to examine the associations between BMI, disordered eating attitude, body dissatisfaction in female adolescents, and descriptive attributes assigned to silhouettes of varying sizes in male and female adolescents, aged 11 to 15, in rural South Africa. Height and weight were measured to determine BMI. Age and sex-specific cut-offs for underweight and overweight/obesity were determined using the International Obesity Task Force cut-offs. Body image satisfaction using Feel-Ideal Discrepancy (FID scores, Eating Attitudes Test-26 (EAT-26, and perceptual female silhouettes were collected through self-administered questionnaires in 385 adolescents from the Agincourt Health and Socio-Demographic Surveillance System (HSDSS. Participants self-reported their Tanner pubertal stage and were classified as early pubertal ( 2. Mid to post pubertal boys and girls were significantly heavier, taller, and had higher BMI values than their early pubertal counterparts (all p<0.001. The prevalence of overweight and obesity was higher in the girls than the boys in both pubertal stages. The majority (83.5% of the girls demonstrated body dissatisfaction (a desire to be thinner or fatter. The girls who wanted to be fatter had a significantly higher BMI than the girls who wanted to be thinner (p<0.001. There were no differences in EAT-26 scores between pubertal groups, within the same sex, and between boys and girls within the two pubertal groups. The majority of the boys and the girls in both pubertal groups perceived the underweight silhouettes to be "unhappy" and "weak" and the majority of girls in both pubertal groups perceived the normal silhouettes to be the "best". These findings suggest a need for policy intervention that will address a healthy body size among South African adolescents.

    The excess of weight, mainly obesity, during childhood and adolescence increases morbimortality risk in adulthood. The aim of this article is to estimate both the overall prevalence, as well as according to age and gender, of underweight, overweight, obesity and abdominal obesity among schoolchildren aged between 6-15-years-old in the school year 2013-2014. Data were taken from a cross-sectional community-based study carried out on a representative sample, by gender and age, of the Galician population aged between 6 and 15 years-old. The prevalence of underweight, overweight, and obese children (Cole's cut-off criteria) and abdominal obesity (Taylor's cut-off criteria) were estimated after performing objective measurements of height, weight and waist circumference at school. A total of 7,438 students were weighed and measured in 137 schools. The prevalence of overweight and obese individuals was 24.9% and 8.2%, respectively. The prevalence of abdominal obesity was 25.8%, with 4% of children with normal weight having abdominal obesity. These data highlight the need to promote primary prevention measures at early ages in order to decrease the occurrence of the premature onset of disease in the future. The prevalence of excess weight is underestimated if abdominal obesity is not taken into consideration. Copyright © 2017. Publicado por Elsevier España, S.L.U.

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

    Obesity is widely assumed to be associated with economic affluence; it has therefore been assumed to become more common with economic development. However, obesity has also been associated with poverty. These contrary findings highlight the need for an examination of the contribution of social and economic factors to the global distribution of obesity. Males and females may be differently exposed to social and economic inequality, however few studies have considered possible gender differences in the association between socio-economic indices and obesity prevalence. We analysed between-country associations between obesity prevalence and three social or economic indices: per capita gross domestic product (GDP), the Gini index of national wealth inequality, and the gender inequality index (GII). We considered the genders separately, the gender average, and also the gender difference (female excess) in obesity prevalence. Across 68 countries listing sample size, there were 3 obese women for every 2 obese men. Within populations, obesity prevalence in males and females was strongly correlated (r = 0.74), however, only 17% of the female excess prevalence was accounted for by the gender-average prevalence. In both genders, there was a positive association between obesity prevalence and GDP that attenuated at higher GDP levels, with this association weaker in females than males. Adjusting for GDP, both the Gini index and GII were associated with excess female obesity. These analyses highlight significant gender differences in the global distribution of obesity, and a gender difference in the association of obesity prevalence with socio-economic factors. The magnitude of female excess obesity is not constant across populations, and is greater in countries characterised by gender inequality and lower GDP. These findings indicate that improving women's status may be a key area for addressing the global obesity epidemic over the long term, with potential benefits for the

    The aim of this study was to examine ventilatory responses to training in obese adolescents. We assessed body composition, pulmonary function and ventilatory responses (among which expiratory flow limitation and operational lung volumes) during progressive cycling exercise in 16 obese adolescents (OB) before and after 12 weeks of exercise training and in 16 normal-weight volunteers. As expected, obese adolescents' resting expiratory reserve volume was lower and inversely correlated with thoraco-abdominal fat mass (r = -0.74, p<0.0001). OB presented lower end expiratory (EELV) and end inspiratory lung volumes (EILV) at rest and during submaximal exercise, and modest expiratory flow limitation. After training, OB increased maximal aerobic performance (+19%) and maximal inspiratory pressure (93.7±31.4 vs. 81.9±28.2 cm H2O, +14%) despite lack of decrease in trunk fat and body weight. Furthermore, EELV and EILV were greater during submaximal exercise (+11% and +9% in EELV and EILV, respectively), expiratory flow limitation delayed but was not accompanied by increased V(T). However, submaximal exertional symptoms (dyspnea and leg discomfort) were significantly decreased (-71.3% and -70.7%, respectively). Our results suggest that exercise training can improve pulmonary function at rest (static inspiratory muscle strength) and exercise (greater operating lung volumes and delayed expiratory flow limitation) but these modifications did not entirely account for improved dyspnea and exercise performance in obese adolescents.

    Full Text Available Introduction Childhood obesity is one of the most serious public health challenges of the 21st century. The problem is global and is steadily affecting many low‐income and middle‐income countries. Childhood obesity is associated with higher chances of premature deaths and disabilities in adulthood. It is also evident that nearly 75% of the obese adolescents remain obese as adults thus increasing the risk of Non Communicable Diseases (NCDs. Aim and Objectives To study the prevalence and associated socio‐demographic factors of overweight and obesity among rural school going adolescents. Material and Methods The present study was conducted in Lakhanmajra block of Rohtak district over a period of one year from July 2016 to June 2017. 750 students from six co‐ educational government senior secondary schools were included in the study. Data were collected using pre‐designed, pre‐tested, semi structured interview schedule. Collected data were analyzed using SPSS version 20.0. Results Prevalence of overweight and obesity was 6.7% and 1.1% respectively. Maximum prevalence of obesity/overweight was found in the age group 13‐14 years (11.2%. Obesity/overweight was more prevalent in males (9.4% in comparison to females (3.4%. 14.3% of the study subjects belonging to three generation family, 11.7% belonging to joint and 4.5% belonging to the nuclear families were found to obese/ overweight. 11% and 5.1% of the study subjects with 6‐10 family members and 5 and less than five family members were obese/ overweight. Conclusion Childhood obesity continues in adult life and thus gives rise to diabetes and cardiovascular diseases. Thus it is the need of the hour to address this problem and to devise programs and strategies to prevent overweight/obesity among children and adolescents because today’s children are future of the nation.

    Current guidelines for the prevention of obesity in childhood and adolescence are presented. A literature search was performed in Medline via PubMed, and appropriate studies were analysed. Programs to prevent childhood obesity were to date mainly school-based. Effects were limited to date. Analyses tailored to different age groups show that prevention programs have the best effects in younger children (adolescence, school-based interventions were most effective when adolescents were directly addressed. To date, obesity prevention programs have mainly focused on behavior oriented prevention. Recommendations for condition oriented prevention have been suggested by the German Alliance of Non-communicable Diseases and include one hour of physical activity at school, promotion of healthy food choices by taxing unhealthy foods, mandatory quality standards for meals at kindergarten and schools as well as a ban on unhealthy food advertisement addressing children. Behavior oriented prevention programs showed hardly any or only limited effects in the long term. Certain risk groups for the development of obesity are not reached effectively by available programs. Due to the heterogeneity of available studies, universally valid conclusions cannot be drawn. The combination with condition oriented prevention, which has to counteract on an obesogenic environment, is crucial for sustainable success of future obesity prevention programs. © Georg Thieme Verlag KG Stuttgart · New York.

    Given the increasing prevalence of obesity among Iranian adolescents and the role of consumption of unhealthy snacks in this issue, interventions that focus on factors influencing food choice are needed. This study was designed to delineate factors associated with unhealthy snack use among female Iranian adolescents. The theory of Planned Behavior served as the framework of the study. Qualitative data were collected via nine focus group discussions in two middle schools (6(th) to 8(th) grades) in a socio-economically diverse district in the city of Tehran in spring 2008. The study sample included 90 female adolescents aged 12-15 years. The sampling strategy was purposive method. Data analyzed using the "framework" method. Major factors identified by the respondents were taste, peer pressure, parental influence, easy access to unhealthy snacks, limited availability of healthy snacks, appeal of snacks, habit, high price of healthy snacks, and media advertisements. Nutritional value and healthiness was not one of the first priorities when buying snacks, as adolescents thought it was too early for them to worry about illness and adverse consequences of eating junk foods. For developing culturally sensitive evidence-based interventions that can motivate adolescents to choose healthy snacks, a broad range of factors should be taken into account.

    Loneliness is one of the psychological characteristics in adolescence, during which sex hormones are elevated. The elevation of sex steroid hormones is known to sculpture and remodel neuronal circuits, which cause behavioral characteristics in adolescence. The aim of the present study is to investigate the relationship between loneliness and sex steroid hormones, testosterone (T) and 17β-estradiol (E2). Fifty-eight adolescents (28 boys and 30 girls) participated in this study. The salivary levels of T and E2 were measured by Enzyme-Linked Immunosorbent Assay (ELISA). Loneliness was assessed by the UCLA loneliness scale, which is widely used as a self-administered questionnaire. The results showed that Salivary E2 levels had positive relevance to loneliness in females, whereas there was no relationship in males. Salivary T level was not shown to be relevant with loneliness in either sex group. These findings suggest that E2 has gender specific effects on loneliness in adolescent females.

    There are specific relation properties of mother to the obese child. The mother representation in child is understand as a experience manner of herself. Representation (mental image) include perceptions, knowledge about characteristics and behaviors of a person and evaluation and experiences that provoke in others. The aim of this article is a trial of an answer what is a mental representation of mother experienced by obese girls and boys in adolescence. 21 obese persons (12 girls and 9 boys) and 23 persons of normal body mass (15 girls and 8 boys) have been investigated. The mean age of the investigated obese persons were 14.53, and for a person of normal body mass was 15.31. All persons were investigated by a clinical interview with 6 questions concerning mental mother representation. The obtained results were analyzed in relation to mental mother representation contents: cognitive, emotional, social, sexual, certificate, behavioral and somatic. Obese persons more often than the person of the normal body mass identify to mental mother representation somatic contents, more rarely social, sexual and behavioral contents. Obese girls more rarely than girls of the normal body mass identify to social contents, more often to somatic. Obese girls more rarely than obese boys identify to mental mother representation emotional contents, more often to somatic contents. The specific relation properties of mother to obese person in adolescence could be manifested in difficulties in turn on contents of mental mother representation, in external, somatic point of concern for mental mother representation, difficulties in contact with mental contents of mother representation.

    This study examined adherence to a personalized, community-based exercise intervention by sedentary adolescents with type 1 or type 2 diabetes or those with obesity. We conducted a pretest-posttest investigation to explore the application of an individualized exercise prescription based upon current fitness level for 39 adolescents (20 with type 1 diabetes, 9 with type 2 diabetes, and 10 obese) over 16 weeks in community settings. Subjects were recruited from a university-based pediatric endocrinology clinic in the southwestern United States. Adherence to the exercise prescription was monitored using accelerometers over the entire intervention period. Moderate-to-vigorous physical activity (MVPA) levels significantly increased over sedentary baseline values (p exercise is challenging. Personalized approaches that include adolescent choices with family support and ongoing motivation can improve individual exercise adherence and a sense of personal health.

    Although controversial, bariatric surgery is increasingly being performed in adolescents. We developed a model to simulate the effect of timing of gastric bypass in obese adolescents on quantity and quality of life. A Markov state-transition model was constructed comparing two treatment strategies: gastric bypass surgery at age 16 versus delayed surgery in adulthood. The model simulated a hypothetical cohort of adolescents with body mass index of 45kg/m(2). Model inputs were derived from current literature. The main outcome measure was quality and quantity of life, measured using quality-adjusted life-years (QALYs). For females, early gastric bypass surgery was favored by 2.02 QALYs compared to delaying surgery until age 35 (48.91 vs. 46.89 QALYs). The benefit was even greater for males, where early surgery was favored by 2.9 QALYs (48.30 vs. 45.40 QALYs). The absolute benefit of surgery at age 16 increased; the later surgery was delayed into adulthood. Sensitivity analyses demonstrated that adult surgery was favored only when the values for adverse events were unrealistically high. In our model, early gastric bypass in obese adolescents improved both quality and quantity of life. These findings are useful for surgeons and pediatricians when counseling adolescents considering weight loss surgery. Copyright © 2016 Elsevier Inc. All rights reserved.

    Obesity is one of the best-documented outcomes of screen media exposure. Many observational studies find relationships between screen media exposure and increased risks of obesity. Randomized controlled trials of reducing screen time in community settings have reduced weight gain in children, demonstrating a cause and effect relationship. Current evidence suggests that screen media exposure leads to obesity in children and adolescents through increased eating while viewing; exposure to high-calorie, low-nutrient food and beverage marketing that influences children's preferences, purchase requests, consumption habits; and reduced sleep duration. Some evidence also suggests promise for using interactive media to improve eating and physical activity behaviors to prevent or reduce obesity. Future interdisciplinary research is needed to examine the effects of newer mobile and other digital media exposures on obesity; to examine the effectiveness of additional interventions to mitigate the adverse effects of media exposures on obesity and possible moderators and mediators of intervention effects; to effectively use digital media interventions to prevent and reduce obesity; and to uncover the mechanisms underlying the causal relationships and interactions between obesity-related outcomes and media content, characteristics, and context.

    Limited data are available on the characteristics of adolescents with obesity who seek bariatric surgery. Existing data suggest that adolescent surgery candidates have a higher body mass index (BMI) than comparison adolescents with obesity, but the limited findings regarding psychosocial functioning are mixed. This study aimed to compare BMI and psychosocial functioning among adolescent bariatric surgery candidates, outpatient medical-treatment-seeking adolescents with obesity (receiving lifestyle modification), and adolescents in the normal-weight range. All adolescents completed self-report measures of impulsivity, delay discounting, depression, anxiety, stress, eating pathology, family functioning and quality of life, and had their height and weight measured. Adolescent surgical candidates had higher BMIs than both comparison groups. Surgical candidates did not differ from medical-treatment-seeking adolescents with obesity on any measure of psychosocial functioning, but both groups of adolescents with obesity reported greater anxiety and eating pathology and poorer quality of life than normal-weight adolescents. Quality of life no longer differed across groups after controlling for BMI, suggesting that it is highly related to weight status. Adolescents with obesity may experience greater anxiety, eating pathology, and quality of life impairments than their peers in the normal-weight range regardless of whether they are seeking surgery or outpatient medical treatment. Clinical implications and directions for future research are discussed. © 2017 World Obesity Federation.

    Breast cancer is the most common cancer among women in Malaysia, about one in 19 women being at risk. This study aimed to investigate knowledge and practice of breast self-examination (BSE), as well as knowledge of risk factors for breast cancer amongst female adolescents in Malaysia. Subsequently, relationships between demographic characteristics and knowledge level of BSE, risk factors for breast cancer and BSE practice were assessed. A descriptive, cross sectional survey was conducted using a sample of 500 Malaysian adolescents from the age of 15 to 19 years. A self-administered questionnaire was used to gather socio- demographic characteristics, knowledge of BSE, knowledge of risk factors for breast cancer and BSE practices. The findings of this study indicated that female adolescents in Malaysia demonstrated an inadequate knowledge level of BSE and risk factors for breast cancer. Only 27.8% of female adolescents performed BSE regularly. BSE practice, knowledge of BSE and knowledge of risk factors for breast cancer showed significant positive relationships. The study highlighted the importance of planning and implementing breast health education programs for female students in secondary schools in Malaysia. It will also provide the health care providers an avenue to stress on the importance of imparting breast health education to adolescents.

    Despite alarming prevalence rates, surprisingly little is known about neural mechanisms underlying eating behavior in juveniles with obesity. To simulate reactivity to modern food environments, event-related potentials (ERP) to appetizing food images (relative to control images) were recorded in adolescents with obesity and healthy adolescents. Thirty-four adolescents with obesity (patients) and 24 matched healthy control adolescents watched and rated standardized food and object images during ERP recording. Personality (impulsivity) and eating styles (trait craving and dietary restraint) were assessed as potential moderators. Food relative to object images triggered larger early (P100) and late (P300) ERPs. More impulsive individuals had considerably larger food-specific P100 amplitudes in both groups. Controls with higher restraint scores showed reduced food-specific P300 amplitudes and subjective palatability ratings whereas patients with higher restraint scores showed increased P300 and palatability ratings. This first ERP study in adolescents with obesity and controls revealed impulsivity as a general risk factor in the current obesogenic environment by increasing food-cue salience. Dietary restraint showed paradoxical effects in patients, making them more vulnerable to visual food-cues. Salutogenic therapeutic approaches that deemphasize strict dietary restraint and foster healthy food choice might reduce such paradoxical effects. © 2015 The Obesity Society.

    Self-esteem is a major "predictor" of satisfaction with life. This longitudinal study examined mean and individual changes in self-esteem, and how self-esteem is affected by race and body mass. Girls were recruited at ages 9 and 10 years, and followed to age 22 years. The Harter Self-Perception Profile was administered every other year, analyzing scores from the Global Self-Worth Scale, by age or developmental phase: ages 9-12 (I), 13-16 (II), and 17-22 (III). Regression modeling included main effects and interactions between age/phase, race, and body mass index (BMI). Self-worth was greater in black than white women, and greater with lower BMI in both races. In the model with age ("traditional model") (with race and BMI), significant variables included BMI (inverse relationship) and the interactions between age and race, race and BMI, and the triple interaction between age, race, and BMI. In the model with phase ("transitional model") (with race and BMI), BMI, and the interactions between BMI and race, and race and phase, were significant. For example, self-worth was generally lower in Phase II (middle adolescence) for white women. Self-esteem tracked significantly (correlation 0.22, p self-esteem in adolescent girls, race and BMI are important predictors of self-esteem. Self-esteem is consistent across the phases of adolescence, and comparable with other personality traits. As noted by others, lower levels of self-esteem may increase the vulnerability of adolescents to risky behaviors.

    Full Text Available Abstract Sexual behavior of HIV-positive youths, whether infected perinatally, through risky behavior or other ways, is not substantially different from that of HIV-uninfected peers. Because of highly active antiretroviral therapy, increasing number of children, infected perinatally, are surviving into adolescence and are becoming sexually active and need reproductive health services. The objective of this article is to review the methods of contraception appropriate for HIV-positive adolescents with a special focus on hormonal contraceptives. Delaying the start of sexual life and the use of two methods thereafter, one of which is the male condom and the other a highly effective contraceptive method such as hormonal contraception or an intrauterine device, is currently the most effective option for those who desire simultaneous protection from both pregnancy and sexually transmitted diseases. Health care providers should be aware of the possible pharmacokinetic interactions between hormonal contraception and antiretrovirals. There is an urgent need for more information regarding metabolic outcomes of hormonal contraceptives, especially the effect of injectable progestins on bone metabolism, in HIV-positive adolescent girls.

    Full Text Available Background : This study aimed to investigate the association of overweight and obesity with red and white meat intake among children and adolescents using secondary survey data (n=16,261 from in-school Student Health Examination conducted in 2006 and 2007. Methods : Descriptive statistics was conducted to investigate the frequency of meat intake per week. The body mass index (BMI grades for obesity in boys and girls were classified using the standards from the 2007 Korean National Growth Charts. The association of meat intake with overweight and obesity was analyzed using Chi-square test and multiple logistic regression. Results : The proportion of subjects with no intake/week vs. daily meat intake/week was 5.9% and 5.5%, respectively. No intake of meat was more frequent in those who were female and in middle school, whereas daily meat intake was more frequent in those who were male and in high school. The proportions of overweight and obesity in the no meat intake/week group and daily meat intake/week group were 12.3% and 11.1% vs. 8.1% and 9.9%, respectively. After adjusting for confounding variables, including age; consumption of instant noodles, soft drinks and fast foods, dairy products, and fruits and vegetables; and skipping breakfast, the odds ratios of overweight and obesity in the no meat intake/week group were 1.41 times higher (95% confidence interval, 1.04–1.85 than those in the daily meat intake/week group. Conclusion : It is important to consider correcting the perception about meat intake and obesity and avoid restricting meat intake to prevent overweight and obesity among children and adolescents.

    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 (pP90). 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.

    Full Text Available Abstract Background 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. Methods 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. Results 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 (pP90. Conclusion 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.

    The increased frequency of extreme forms of obesity in adolescents and the disappointing results of conventional treatments are now leading pediatricians to consider bariatric or cosmetic surgery as the only real long-term effective therapeutic alternative. The two main techniques currently used for bariatric surgery in adolescents are gastric bypass and adjustable gastric banding. Whatever the technique, weight loss is significant with improvement of comorbidities and quality of life. In addition, the complications are identical to those in adults and equally frequent. However, because of the particularities of this age, caution is still required. Adolescence is indeed characterized by specific nutritional needs, but also changes in body image in which surgery could have a negative effect. Currently, all obese teenagers making a request for bariatric surgery should have a comprehensive assessment with global care for at least 6 months. The indication is then discussed on a case-by-case basis by multidisciplinary teams and experts. To date, the type of surgery (gastric banding, gastric sleeve, or bypass) is still widely discussed. Based on experience with adults, we believe that gastric sleeve and bypass should be preferred. In addition, obesity in adolescents almost always involves psychosocial consequences, while somatic complications are rare. Thus, the care of adipo- or gynecomastia, abdominal fat excess, and concealed penis is essential and therefore justifies cosmetic surgery. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    To investigate the detection rates of overweight and obesity among Han,Uygur and Kazakh Children and adolescents in Xinjiang. Random samples were used to analyze the detection rates on overweight and obesity based on data from Han,Uygur and Kazakh Children and adolescents aged 7-14 years from 3 regions-Hetian, Kashi and Fuhai prefectures in Xinjiang Uygur Autonomous Region. Anthropometric data including weight and height was collected. Overweight and obesity were defined according to body mass index [BMI, weight (kg)/height (m²)] cutoffs recommended by the Chinese Working Group on Obesity for Children (WGOC)aged 7-14 years. The present study was performed in 11 894 Han, Uygur and Kazakh Children and adolescents aged 7-14 years. The overall prevalence rates of overweight and obesity were 5.6% and 2.9% respectively, which the difference between male and female was significant (χ² = 39.765, P overweight and obesity rate showed differences, with detection rate of overweight among Kazakh students was 12.0% , higher than the other ethnic groups. The obesity detection rate was 7.2% among Han students, which was the highest of the three ethnic groups, with differences statistically significant(χ² = 363.885, P overweight and obesity decreased with increasing age in various ethnic groups, showing a clear downward trend, with the peak at 7-9 year-olds and the difference was statistically significant(χ² = 101.479, P overweight and obesity among children and adolescents were significantly lower in Xinjiang Uygur Autonomous Region than the national average level, with differences also seen in different ethnic, gender and age groups.

    Full Text Available IntroductionAs with most emerging nations, Brazil lacks up-to-date data on the prevalence of obesity and overweight among its children. Of particular concern is the lack of data on children in early adolescence, considered by many to be the crucial stage for weight-related healthcare.ObjectiveTo assess regional, socioeconomic, and gender differences in the prevalence of obesity and overweight among Brazilian early adolescents.MethodsA cross-sectional study was conducted on a racially diverse sample of students aged 10–13 years, from schools in three geographic regions (north, northeast, south (N = 1,738. Data on gender, age, race, socioeconomic status (SES, weight, and height were obtained. Weight class was calculated from age- and gender-adjusted body mass index, based on children’s weight and height. Bivariate and multivariable analyses, with post hoc tests, were conducted to estimate differences between groups and were corrected for multiple comparisons. Procedures were approved by institutional review boards at study sites.ResultsAnalyses revealed a higher prevalence of obesity and/or overweight among: (1 children of higher SES; (2 children in southern Brazil; (3 males; and (4 Black females.ConclusionThe most salient predictor of weight risk among Brazilian early adolescents is higher SES. This finding is consistent with previous findings of an inverse social gradient, in weight risk, among emerging-nation population groups.

    Full Text Available 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.

    Obesity in childhood and adolescence has important health consequences, but its relation to risk of adult depression remains uncertain. To examine the effect of perceived and actual obesity during childhood and adolescence on prevalence and incidence of adult depression risk. Cohort study of 91,798 female registered nurses followed longitudinally for 12 years. As compared with lean women of the same age, women in the two highest categories of body shape at age 10 had both higher prevalence (OR=2.59, 95% CI 1.46 to 4.61) and incidence (OR=2.01, 95% CI 1.08 to 3.71) of depression. Similar results were obtained for body shape at age 20 (OR=3.43 for prevalence and OR=2.03 for incidence) and for body mass index (BMI) at age 18 (OR=2.92 for BMI ≥ 40 kg/m(2)). These associations remained significant after adjustment for multiple confounders. These results indicate that childhood-adolescence obesity is a strong and independent risk factor for adult depression.

    Full Text Available Our aim was to assess cardiovascular risk factors that may predict increased carotid intima media thickness (cIMT in obese children and adolescents. Children and adolescents were included in the cross-sectional study if they were aged 9-19 years and had primary obesity. Besides anthropometric and biochemical measurements, ambulatory blood pressure monitoring, measurement of carotid intima media thickness and exercise stress test were performed. We included 103 obese patients and divided them according to the ambulatory blood pressure findings in two groups: obese patients with and without ambulatory hypertension. There were 49 obese patients with and 54 without ambulatory hypertension Univariate analysis showed that there was a significant positive correlation of cIMT with age (r = 0.334, p= 0.001, body mass index (r = 0.288, p = 0.004, waist circumference (r = 0.352, p = 0.000, hip circumference (r = 0.288, p = 0.004, night-time systolic blood pressure (r = 0.226, p = 0.027, and peak diastolic blood pressure on exercise test (r = 0.241, p = 0.018. In a stepwise model, age, waist circumference and peak diastolic blood pressure on exercise test were independent predictors of cIMT.

    The highest rates of sexually transmitted infections in the U.S. occur among adolescent females. One prevention strategy promoted for sexually active adolescents is condom use: therefore, influences on correct and consistent condom use are worth examining. Because interventions and observational research into predicting and increasing condom use have yielded mixed results, we hypothesized that a theoretically driven model incorporating female adolescents' perceptions about partner sentiments along with their own perceptions, intentions, and behaviours would improve condom use predictions. We also measured condom use errors and consistency for a more precise estimate of effective use than is common in the literature. In three structural equation models tested on a sample of 519 female adolescents, we found that intentions were associated with both correct and consistent condom use; that females' expectancy beliefs about condom use were associated with intentions; and that females' expectancy beliefs about partners' sentiments reduced the impact of their expectancy beliefs about condom use. The implications of these relations upon condom use correctness and consistency are discussed with respect to informing interventions, among other future research.

    The association between obesity during adolescence and the increased risk of cardiometabolic diseases indicates the need to identify reproducible and cost effective methods for identifying individuals who are at increased risk of developing diseases. The present cross-sectional study investigated the occurrence of metabolic consequences of obesity in adolescents and the use of adiposity indicators as predictors of cardiometabolic risk. A fasting blood sample was taken in 93 pubertal obese adolescents aged 13-18 years old (39 males, 54 females) for the assessment of cardiometabolic risk markers (glucose, lipid profiles, insulin resistence, and inflammatory and endothelial dysfunction markers). Together with anthropometry, total fat mass and lean mass were determined by dual-energy X-ray absorptiometry (DXA). The prevalence of dyslipidaemia and disorders in glucose metabolism are noticeably higher in the present study. There was no correlation between the percentage of body fat according to DXA and most indicators of adiposity. For boys, the arm circumference values predicted the increase in fasting insulin (r² = 0.200), homeostasis model assessment of insulin resistance (r² = 0.267) and cardiometabolic risk score (r² = 0.338). The percentage of body fat according to DXA predicted the inflammation score (r² = 0.172). For girls, body mass index was the parameter that best described the variability of fasting insulin (r² = 0.079) and inflammation score (r² = 0.263). The waist-to-stature ratio was able to predict the triglyceride values (r² = 0.090). Anthropometric measures of adiposity, such a body mass index, waist-to-stature ratio, arm circumference and waist circumference,should be considered in the clinical evaluation of obese adolescents. © 2016 The British Dietetic Association Ltd.

    Full Text Available Introduction: Obesity is strongly associated with coronary heart disease and it is known as an independent risk factor. So, the aim of this study was to investigate the effects of phase II comprehensive cardiac rehabilitation program on obesity indexes, functional capacity, lipid profiles, and fasting blood sugar in obese and non-obese female patients with coronary heart disease and to compare changes in these groups. Materials and Methods: Two hundred and five women with coronary heart disease participated in our study. At the beginning of study, body mass index, functional capacity, and lipid profiles and fasting blood sugar were evaluated; then, these patients were divided into two groups, patients who had BMI≥30 were known as obese and who had BMI<30 were known as non-obese patients. All of them completed the period of cardiac rehabilitation program, and 2 months later, all risk factors were examined for the second time in each group. Data were analyzed with SPSS software version 15. For comparing the mean of outcomes, independent t-tests and paired t-tests were used. Results: Data revealed that unless in weight (P=0.00 and functional capacity (P=0.001, there were no significant differences in obese and non-obese female patients, at baseline. As a result of the cardiac rehabilitation program, both groups had significant improvement in functional capacity (P=0.00, weight reduction (P=0.00, triglyceride (P=0.01 and P=0.02, respectively, low-density lipoprotein cholesterol (P=0.01, and low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (P=0.00 and P=0.003, respectively. As well, significant improvement was observed in high-density lipoprotein (P=0.01 only in obese female, and non-obese female had significant differences in total cholesterol (P=0.003. However, there were not significant changes in total cholesterol (P=0.05 and fasting blood sugar (P=0.09 in obese female. Also, non-obese females didn′t have

    The aim of this study was to investigate the prevalence of obesity, dietary habits, and sedentary patterns among Sudanese adolescents. A multistage stratified sampling method was used to select 945 adolescents (507 males and 438 females) aged 14 to 18 years, from Khartoum State, Sudan. A self-reported pretested questionnaire was used to collect the data. Overweight and obesity were determined using the International Obesity Task Force standard, which is based on body mass index for sex and age. Overweight and obesity were growing problems among urban Sudanese adolescents (10.7%). Breakfast was commonly consumed on a daily basis by the majority of adolescents (74.2%), followed by lunch (63.9%) and supper (33.5%). Snacking was not a common practice among these individuals. Vegetables (63.9%) were more frequently consumed (more than 3 days per week) than fruit (30.1%). There were significant differences between genders regarding intake of vegetables (P Sedentary behaviors (long duration of television viewing and Internet use) were highly prevalent, and physical activity was rarely practiced (6.8%). The findings indicated that risk factors for diet-related chronic diseases such as unhealthy dietary habits and sedentary behaviors are starting to rise among urban adolescents in Sudan. This creates the need for immediate action to prevent and control these risk factors before these diseases become major public health problems. © The Author(s) 2016.

    Having an excess of body fat has been identified as a predictor for participatory frequency in physical activity, a behavior that influences the development and persistence of obesity. However, the psychological factors that contribute to this pathway have not been as easily identified. This is particularly significant for population subgroups that are not only uniquely impacted by obesity-related morbidities but who are underrepresented in research as well. This study sample consisted of African-American adolescent females (N = 310), from 14 to 18 years of age, who were recruited from the urban South. Data obtained from self-reported and demographic questionnaires, as well as from anthropometric measurements, were analyzed to explore the mediating effect of global self-worth between BMI and physical activity. Mediation analysis revealed that 2% of the influence that BMI exerts on how frequently African-American adolescent females engaged in physical activity can be attributed to global self-worth.

    Obesity, elevated blood pressure (BP) and arterial stiffness are risk factors for cardiovascular disease. A strong relationship exists between obesity and elevated BP in both children and adults. Obesity and elevated BP in childhood track into adult life increasing the risk of cardiovascular disease in adulthood. Ambulatory BP is the most precise measure to evaluate the BP burden, whereas carotid-femoral pulse wave velocity (cfPWV) is regarded as the gold standard for evaluating arterial (i.e. aortic) stiffness. These measures might contribute to a better understanding of obesity's adverse impact on the cardiovascular system, and ultimately a better prevention and treatment of childhood obesity. The overall aim of the present PhD thesis is to investigate arterial stiffness and 24-hour BP in obese children and adolescents, and evaluate whether these measures are influenced by weight reduction. The present PhD thesis is based on four scientific papers.  In a cross-sectional design, 104 severe obese children and adolescents with an age of 10-18 years were recruited when newly referred to the Children's Obesity Clinic, Holbæk University Hospital, and compared to 50 normal weighted age and gender matched control individuals. Ambulatory BP was measured, and cfPWV was investigated in two ways in respect to the distance measure of aorta; the previously recommended length - the so called subtracted distance, and the currently recommended length - the direct distance. In a longitudinal design, the obese patients were re-investigated after one-year of lifestyle intervention at the Children's Obesity Clinic in purpose of reducing the degree of obesity. In the cross-sectional design, the obese group had higher measures of obesity, while matched for age, gender and height, when compared to the control group. In the longitudinal design, 74% of the 72 followed up obese patients experienced a significant weight reduction. CfPWV was dependent on the method used to measure the

    Objective: Obesity and insulin resistance (IR) predispose to type 2 diabetes mellitus. Yet only half of obese adolescents have IR and far fewer progress to type 2 diabetes mellitus. We hypothesized that amino acid and fatty acid metabolites may serve as biomarkers or determinants of IR in obese teens. Research Design and Methods: Fasting blood samples were analyzed by tandem mass spectrometry in 82 obese adolescents. A principal components analysis and multiple linear regression models were used to correlate metabolic components with surrogate measures of IR: homeostasis model assessment index of insulin resistance (HOMA-IR), adiponectin, and triglyceride (TG) to high-density lipoprotein (HDL) ratio. Results: Branched-chain amino acid (BCAA) levels and products of BCAA catabolism were higher (P BCAA, uric acid, and long-chain acylcarnitines and negatively with byproducts of complete fatty acid oxidation (R2 = 0.659, P < .0001). In contrast, only BMI z-score correlated with HOMA-IR in females. Adiponectin correlated inversely with BCAA and uric acid (R2 = 0.268, P = .0212) in males but not females. TG to HDL ratio correlated with BMI z-score and the BCAA signature in females but not males. Conclusions: BCAA levels and byproducts of BCAA catabolism are higher in obese teenage boys than girls of comparable BMI z-score. A metabolic signature comprising BCAA and uric acid correlates positively with HOMA-IR in males and TG to HDL ratio in females and inversely with adiponectin in males but not females. Likewise, byproducts of fatty acid oxidation associate inversely with HOMA-IR in males but not females. Our findings underscore the roles of sex differences in metabolic function and outcomes in pediatric obesity. PMID:25202817

    Objective: In this study, our aim was to determine cardiovascular risk and cardiac function in prediabetic obese children and adolescents. Methods: The study was conducted on 198 obese children and adolescents 6-18 years of age. Anthropometric measurements, blood pressure measurements, oral glucose tolerance test, lipid profile, and HbA1c levels of patients were assessed. Prediabetes was defined according to American Diabetes Association criteria. Left ventricular mass index (LVMi), carotid intima-media thickness (c-IMT), and tissue Doppler measurements records were used. Results: LVMi was found to be significantly higher in the prediabetes group (p=0.03). There were no statistically significant differences in right ventricular tissue Doppler measurements between the prediabetic and non-prediabetic groups. Left ventricular tissue Doppler measurements were significantly higher in the prediabetes group: LVEEM (left ventricular E/e ratio) (p=0.04); LVEM (left ventricular myocardial velocity cm/s) (p=0.035). LVMi was found to positively correlate with triglyceride level, diastolic blood pressure, waist circumference, body weight standard deviation score and to negatively correlate with high-density lipoprotein cholesterol (p=0.043, r=0.15; p=0.039, r=0.15; p=0.025, r=0.17; p=0.009, r=0.19; p=0.038, r=-0.15, respectively). LVEM was correlated with glucose (p=0.046, r=0.15) and LVEEM was correlated with systolic blood pressure (p=0.035, r=0.15). In linear regression analysis for clinical cardiovascular risk factors, fasting glucose level was the best predictor of LVEM. Conclusion: In this study, deterioration of cardiac function in prediabetic obese children and adolescents was shown. We recommend determining cardiovascular risk and cardiac dysfunction at early stages in prediabetic obese children and adolescents. PMID:26759114

    Hyperuricaemia has been suggested as an additional metabolic factor in adult obese patients, but it has not been sufficiently studied in paediatric. To assess the relationship between serum uric acid levels (SUAL) with the level of general and visceral obesity, and other biochemical parameters in children and adolescents of Santiago, Chile. A cross sectional study was conducted on 770 children and adolescents (ages: 6-15 y.) from a public school in Santiago, Chile, of whom 227 (29%) were obese (BMI>2 SD, WHO growth standards). Ninety subjects were randomly selected and 77 with no other chronic disease (41 males) accepted to participate. Data was collected on weight, stature, abdominal circumference (AC), visceral adiposity using ultrasound, and other biochemical measurements including fasting glucose, insulin, serum lipids, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and SUAL. The mean SUAL was 0.200±0.065 mmol/L, and was increased in children with hyperinsulinism (adjusted by age: 0.221±0.075 vs. 0.183±0.054 mmol/L; Por<26 U/mL: 0.238±0.070 vs. 0.178±0.054 mmol/L, P<.001. The logistic regression showed the increased SUAL was only associated with increased ALT. No significant differences were found in general or visceral adiposity measurements or fatty liver. Children and adolescents from Santiago, Chile have higher uric acid serum uric acid levels as well as an association with increased ALT and insulin. It is demonstrated in this study that uric acid should be measured in obese children and adolescents, and in their follow up. Copyright © 2015 Sociedad Chilena de Pediatría.

    The current literature on determinants of behavior change in weight management lacks sufficient studies on type of motivation among children/adolescents, on perceived competence, and in relation to healthy eating. This study aimed to investigate type of motivation and levels of perceived competence for healthy diet and exercise, as well as general self efficacy among adolescents. We hypothesized that overweight/obese adolescents would demonstrate lower autonomous motivation and perceived competence regarding diet and exercise, and lower self-efficacy in general, and that the scores would be influenced by socioeconomic factors. Normal weight ( n  = 40, body mass index Competence Scale (PCS) for healthy eating and exercise, and the General Self-Efficacy Scale (GSES). Composite scores for the three scales were compared between the two groups using the using the two-sample t-test (for normal data) or the Mann-Whitney U test (for non-parametric data). Relationships between the composite scores and patient characteristics were determined using Pearson or Spearman's correlations. The average age of the total cohort was 15.9 ± 1.9 years. 54% were female, and 82% identified as Latino/Hispanic. In comparison to normal weight subjects, overweight/obese adolescents exhibited higher scores for controlled motivation (mean ± standard deviation 28.3 ± 9.3 vs 18.1 ± 8.1) and higher perceived competence [median and 25-75% interquartile range 22.5 (19.0-26.0) vs 20.0 (15.5-25.0)] in relation to eating a healthy diet. These differences persisted after adjustment for age, sex, paternal education, and family income. Overweight/obese adolescents did not lack autonomous motivation but demonstrated higher controlled motivation and perceived competence for healthy eating in comparison to normal weight adolescents, independent of socioeconomic factors. In the clinical practice of weight management, providers should carefully assess adolescents for type of

    To investigate the performance of a simple and developmentally appropriate 10-item questionnaire (Adolescent Binge Eating Scale) for the prediction of binge eating disorder (BED) diagnosis in adolescents seen for obesity. We evaluated the performance of the questionnaire in comparison with a clinical interview, in a population of adolescents being seen for obesity. The ? 2 or Fisher exact tests were used. There were 94 adolescents aged 12-18 years (59.6% girls) who completed the study. The questionnaire demonstrated a good association with the clinical interview and distinguished different levels of risk for having a BED: participants who responded positively to questions 1 or 2 and had more than 6 positive answers to the 8 additional questions had a high risk of subclinical and clinical BED (83.3%); participants with 3 or fewer positive answers had a low risk of clinical BED (4%). The Adolescent Binge Eating Scale questionnaire is a potential screening tool to identify adolescents with obesity at high risk of BED and guide referral to a specialist to clarify the diagnosis and provide adequate care.

    To evaluate the effect of sibutramine on weight loss in obese adolescents. A double-blind controlled study lasting 13 months. The study included 73 obese adolescents of both sexes aged between 10 and 18 years. Laboratory tests and imaging studies were performed before, during wash-out, and at the end of 13 months. The percentage of patients who lost 10% of their initial weight in the placebo group was 46%, and in the sibutramine group was 75%. When placebo was used, average weight rose by 1.61 kg, and BMI decreased by 0.24 kg/m(2) whereas with the use of sibutramine, weight decreased by 4.47 kg, and average BMI decreased, 2.38 kg/m(2), with p Sibutramine induced significantly more weight loss in obese adolescents compared with placebo, without significant side effects. The weight loss curve was different depending on the moment sibutramine was introduced. This finding indicates that the best time to start sibutramine is when adhesion begins to fail.

    Full Text Available Background and Aim: Recent studies on various populations indicate that lack of sleep is one of the potential risk factors predisposing the youth to obesity. Since there is a significant rise in obesity among Indian youth and because research indicating the role of sleep in development of obesity among Indian population is scant, the current study was undertaken to assess the effect of sleep duration on adiposity among Gujarati Indian adolescents. Materials and Methods: A randomized cross-sectional study was done on 489 voluntarily participating Indian adolescents in the age group of 16-19 years. Participants were grouped into two categories 1. Adequate Sleep Duration at Night (more than seven hours, ASDN and 2 Inadequate Sleep Duration at Night (less than seven hours, IASDN as reported by the participants. The participants were later assessed for adiposity in terms of BMI, BF % , FM, FMI and waist circumference, meal frequency per day and physical activity status. Results: In both boys as well as girls, the BMI, BF%, FM and FMI were significantly lower in the ASDN group than the IASDN group. However, there was an insignificant difference in the meal frequency and physical activity status between the ASDN and IASDN group. Conclusion : Inadequate sleep duration increases adiposity among Gujarati Indian adolescents but further studies are required to find out the mechanisms through which sleep affects adiposity in this population.

    The importance of psychological problems for children obesity and the role of the family context in favouring both pathology appearance and maintenance and eventually the failure of a correct dietetic therapy are presented. Particularly, maternal attitudes are underlined: obese children's mothers tend to make the family their exclusive centre of interest. They also tend to dedicate themselves to their children with possessiveness and hyper-protection. They seem to have an insistent requirement of idealisation of their own role as parents and reward expectations that confirm the efficiency of the care they provide their children. Moreover the psychological features of obese adolescents with anxious and depressive personality traits related to impulsivity and emotional immaturity are analysed.

  20. Breastfeeding reduces the risk of obesity in childhood and adolescence

    Full Text Available Childhood obesity has increased dramatically over the last decades, representing one of the most serious public health hazards of the 21st century. Efforts must be made by healthcare professionals to prevent it, as it is associated with short- and long-term risks for physical and mental health and because of the increased possibility to persist during adulthood. From antiquity human breast milk was considered the ideal nourishment for the newborn. Breastfeeding is beneficial for the mother-child dyad. Among others, existing data suggest that it reduces the risk for childhood and adolescence obesity. The mechanisms for this are numerous and include the feeding behavior breastfeeding infants acquire, their growth rate, the ‘early protein hypothesis’, the role of leptin that is found in increased levels in human milk, the dietary choices the breastfed infants make during childhood and adolescence and finally the differences in their bowel flora. Meta-analyses provide sufficient evidence for this protective effect, with a dose-response effect as to the duration of breastfeeding. Healthcare professionals involved in the care of the mother-infant dyad must encourage and support mothers to breastfeed their infants for a long period of time, if obesity were to be prevented. Aim of this review is to provide an account of existing data on the association of breastfeeding and the reduced risk of obesity in childhood and adulthood.

  1. Prevalence and correlates of contraceptive use among female adolescents in Ghana.

    Adolescence is a critical stage in the life course and evidence suggests that even though contraceptive use has been steadily increasing among women in Ghana over the past years, contraceptive prevalence and determinants among female adolescents is quite lacking. This paper examines the prevalence and correlates of contraceptive use among female adolescents in Ghana. The paper used data from the 2008 Ghana Demographic and Health survey. Bivariate analysis was carried out to determine the contraceptive prevalence among female adolescents while logistic regression analysis was applied to examine the correlates of female adolescent contraceptive use. The study founded that female adolescent contraceptive use was significantly determined by age of adolescent, education, work status, knowledge of ovulatory cycle, visit of health facility and marital status. This has implications for adolescent sexual and reproductive health programmes in Ghana. It is therefore essential to intensify girl child education and strengthen the provision of family planning information and services for female adolescents in the country.

    This meta-analysis provides an updated and comprehensive estimate of the effects of obesity on metabolic disorders in adolescent polycystic ovary syndrome (PCOS). Relevant articles consistent with the search terms published up to 31 January 2014 were retrieved from PubMed, EMBASE, PsycINFO and CENTRAL. Thirteen articles (16 independent studies) conformed to the inclusion criteria. The evaluated outcomes were the metabolic parameters of obese adolescents with PCOS (case group) relative to normal-weight adolescents with PCOS, or obese adolescents without PCOS. Compared with normal-weight adolescents with PCOS, the case group had significantly lower sex hormone-binding globulin and high-density lipoprotein cholesterol, and significantly higher triglycerides, leptin, fasting insulin, low-density lipoprotein cholesterol and free testosterone levels. Relative to obese adolescents without PCOS, the case group had significantly higher fasting insulin, low-density lipoprotein cholesterol, free testosterone levels and 2-h glucose during the oral glucose tolerance test. These results indicate that metabolic disorders in adolescent PCOS are worsened by concomitant obesity. This study highlights the importance of preventing obesity during the management of adolescent PCOS. Impact statement What is already known about this subject: Obesity and PCOS share many of the same metabolic disorders, for example, hyperandrogenism and hyperinsulinemia with subsequent insulin resistance. Knowledge regarding metabolic features in obese adolescents with PCOS is limited, and there is concern whether obesity and PCOS are related. What do the results of this study add: Relative to PCOS adolescents of normal weight, obese adolescents with PCOS (the case group) had significantly lower SHBG and HDL-C, and significantly higher triglycerides, leptin, fasting insulin, LDL-C and free testosterone levels. The results indicate that metabolic disorders in adolescent PCOS are worsened by concomitant

    To help identify and advance the understanding of the potential mechanisms underlying the association between parents' and adolescents' psychological maladjustment in obesity, we evaluated bulimic behaviours and psychopathology in a clinical sample of obese adolescents and in their parents. This is a cross-sectional cohort study including 115 severely obese, treatment-seeking adolescents aged 12-17 years (mean age: 14.2; mean body mass index z-score: 4.32), and their parents (115 mothers and 96 fathers). Adolescents filled out the Bulimic Investigatory Test, Edinburgh (BITE), the Beck Depression Inventory (BDI), and the State-Trait Anxiety Inventory for Children (STAIC). Their parents completed the General Health Questionnaire (GHQ) and the BITE. A child psychiatrist filled out the Montgomery and Asberg Depression Rating Scale (MADRS) and the Brief Scale for Anxiety (BSA) for the adolescents. Obese adolescents demonstrated significant correlations between the severity of bulimic symptoms and the degree of emotional symptomatology, such as depression and anxiety, but not with the severity of obesity. Psychopathological maladjustment and bulimic symptoms in obese adolescents were significantly associated with the maternal psychopathological disturbances, especially anxiety and somatisation in mother. In fact, maternal psychopathology, not maternal bulimic symptoms, was the factor most strongly associated with bulimic behaviours in obese adolescents. These results highlight the importance of including an adolescent and parental psychiatric assessment (bulimic, depressive and anxiety symptoms), particularly maternal psychopathology in the treatment of severely obese adolescents.

    To explore the relationship between severity of obesity at age 7 and age 15, age at onset of obesity, and parental body mass index (BMI) in obese children and adolescents. Longitudinal cohort study. Obese children (n = 231) and their parents (n = 462) from the Swedish National Childhood Obesity Centre. Multivariate regression analyses were applied with severity of obesity (BMI standard deviation score (BMI SDS)) and onset of obesity as dependent variables. The effect of parental BMI was evaluated and in the final models adjusted for gender, parental education, age at onset of obesity, severity of obesity at age 7 and obesity treatment. For severity of obesity at age 7, a positive correlation with maternal BMI was indicated (P = 0.05). Severity of obesity at this age also showed a strong negative correlation with the age at onset of obesity. Severity of obesity at age 15 was significantly correlated with both maternal and paternal BMI (P obesity at age 7 and negatively correlated with treatment. Also, a negative correlation was indicated at this age for parental education. No correlation with age at onset was found at age 15. For age at onset of obesity there was no relevant correlation with parental BMI. Children within the highest tertile of the BMI SDS range were more likely to have two obese parents. The impact of parental BMI on the severity of obesity in children is strengthened as the child grows into adolescence, whereas the age at onset is probably of less importance than previously thought. The influence of parental relative weight primarily affects the severity of childhood obesity and not the timing.

  5. Hyperferritinemia and hyperuricemia may be associated with liver function abnormality in obese adolescents.

    Full Text Available The iron status in human body and its association with liver function in adolescents was rarely studied. The objective was to investigate the association among the levels of serum ferritin, uric acid and alanine aminotransferase (ALT in adolescents.A total of 2090 adolescents negative for hepatitis B surface antigen from one junior high school (786, 12-13 years, three senior high schools (973, 15-16 years and one college (331, 18-19 years participated in this survey. Anthropometric and biochemical measurements, including complete blood count, ALT, serum ferritin and uric acid were performed. An ALT>42 U/L was defined as elevated, a ferritin level >200 µg/L was defined as hyperferritinemia. A uric acid level >460 µmol/L in males and >340 µmol/L in females was defined as hyperuricemia. The chi-squared test, linear regression and multivariate logistic regression were used for the data analysis. Elevated ALT levels were detected in 76 (3.6% students and were more prevalent in males than females (6.4% vs. 2.0%, p100 µg/L. The logistic regression analysis found that body mass index, hyperferritinemia and hyperuricemia were significant factors associated with the ALT elevation, but gender, age, and white blood cell count were not.Hyperferritinemia and hyperuricemia are two independently significant factors associated with ALT elevation among obese adolescents. More studies are needed to corroborate any hypothesis related to these phenomena.

    The impact of the age and sex adjusted body mass index (ISO-BMI) in the obese vs. non-obese children and adolescents with cholecystectomy for cholelithias is rarely reported. The national database was searched for cholecystectomies performed in paediatric patients between 1997 and 2011, and the 59 paediatric and adolescent patients having cholecystectomy in the Kuopio University Hospital district were divided in two groups by age and sex adjusted BMI (ISO-BMI) using the cut-off point of overweight (ISO-BMI 25 kg/m(2)) based on the Finnish growth standards. Nationwide a total of 840 cholecystectomies were performed during the 15 years study period in Finland, most of which included females (77%), resulting in a mean of annual frequency of 4.8 (range: 3.9-6.1) procedures/100,000 population. In the study sample, most of the patients with the cholelithiasis were female (50/59, 85%). The gender distribution was equal among the younger patients, but among adolescents 6/52 (12%) of the patients with cholelithiasis were boys and 46/52 (88%) of the patients with cholelithiasis were girls. Obesity did not affect on operative parameters. The median operative time was 70 min (range, 30-155) and 66 min (44-130) in the high ISO-BMI-group. The recovery was similar in the two groups: the median length of hospital stay was 4 days in both groups. The patients in the low ISO-BMI-group vs. high ISO-BMI-group had a trend of higher serum bilirubin (p=0.16) and serum AFOS values (p=0.19). In the histological examination of the gallbladders 19/28 (68%) patients in the low ISO-BMI-group had inflammation vs. 26/31 (84%) patients in the high ISO-BMI-group (p=0.15). Our results between obese and non-obese children and adolescents with cholelithiasis are not statistically significant. The obese adolescents with female gender are in greater risk for cholelithiasis. Copyright © 2014 International Institute of Anticancer Research (Dr. John G. Delinassios), All rights reserved.

    Full Text Available The influence of obesity on cardiometabolic health in the general population has been widely studied, but few studies are dealing with the problem of obesity in children and adolescents with type 1 diabetes. Aim: The aim of this study was to determine the presence of overweight, and obese persons with metabolic syndrome in children and adolescents with type 1 diabetes and to determine the conection of nutritional status with other risk factors for cardiovascular disease, such as dyslipidemia, glycoregulation, high blood pressure , insulin dose, age, illness, length of illness. Methods: The study included 197 children and adolescents with type 1 diabetes mellitus (103 females, 94 males. The average age of respondents was 12,71 years. Data on body weight, height, BMI was calculated according to the formula kg/m2. Standard laboratory procedures were determined, total cholesterol, LDL and HDL cholesterol, AST, GHbA1c, data on a daily dose of insulin, and type of insulin therapy, age at which the disease began, duration of disease, the possible existence of microvascular complications (microalbuminuria, retinopathy, neuropathy and hypertension were obtained. Results: There were 77,2% patients had normal weight, 14,2% were overweight, 3,4% were obese and 5,2% nutritional had metabolic syndrome. We found statistically significant conection between nutritional impairment and total cholesterol, tryglycerides, hypertension, length of disease and daily insuline dose. Conclusion: Due to the fact that people with type 1 diabetes are at high risk for the development of vascular complications, prevention, early detection and treatment of nutritional impairment as well as other cardiometabolic risk factors are imperative.

    Research into lifetime costs of obesity in childhood is growing. This review synthesizes that knowledge. A computerized search of the international literature since 2000 was conducted. Mean total lifetime healthcare and productivity costs were estimated and inflated to 2014 Irish euros. This resulted in 13 published articles. The methodology used in these studies varied widely, and only one study estimated both healthcare and productivity costs. Cognizant of this heterogeneity, the mean total lifetime cost of a child or adolescent with obesity was €149,206 (range, €129,410 to €178,933) for a boy and €148,196 (range, €136,576 to €173,842) for a girl. This was divided into an average of €16,229 (range, €6,580 to €35,810) in healthcare costs and €132,977 (range, €122,830 to €143,123) in productivity losses for boys and €19,636 (range, €8,016 to €45,283) and €128,560, respectively, for girls. Income penalty accounted for the greater part of productivity costs, amounting to €97,118 (range, €86,971 to €107,264) per male adolescent with obesity and €126,108 per female adolescent. Healthcare costs and income penalty appear greater in girls while costs because of workdays lost seem greater in boys. There is proportionality between body mass index and costs. Productivity costs are greater than healthcare costs. © 2017 World Obesity Federation.

    2018-04-01

    Breast development in the female is a process that becomes noticeable during puberty, and defines a girl's transition into adulthood. Various conditions can disrupt or alter the normal development, which may lead to abnormal breast changes and features. Further, the finding of a breast mass in adolescence can be unsettling to the patient and her family. While the majority of these breast changes and/or masses tend to be benign and self-limited, the appropriate evaluation is always warranted. This chapter will focus on the normal and abnormal development of breasts. We will also discuss the evaluation and management of breast masses that can be found in the adolescent female.

    Pervanidou, Panagiota; Chrousos, George P

    2011-09-01

    Chronic distress contributes to the development of obesity and comorbid states. Stress is the disturbance of the complex dynamic equilibrium that all organisms must maintain, and is associated with activation of the Stress system comprising of the hypothalamic-pituitary-adrenal axis and the arousal/sympathetic nervous systems. The stress system functions in a baseline circadian fashion and interacts with other systems of the organism to regulate a variety of behavioral, endocrine, metabolic, immune and cardiovascular functions. The experience of perceived or real uncontrollable intense and/or chronic stress (distress) may lead to several psychopathologic conditions, including anxiety, depressive and psychosomatic disorders, substance abuse, obesity and the metabolic syndrome, and osteoporosis, as well as impaired reproductive and immune functions. Developing children and adolescents are particularly vulnerable to the effects of chronic stress. Both behavioral and biological pathways are involved in the connection between chronic stress and obesity in adults and children. Emotional "comfort" eating, lack of sleep, impulsive behaviours and selection of specific foods often characterize stressed individuals. In addition to specific behaviours, dysregulation of the stress system through increased secretion of cortisol and catecholamines, especially in the evening hours, and in concert with concurrently elevated insulin concentrations, leads to development of central obesity, insulin resistance and the metabolic syndrome. In children, chronic alterations in cortisol secretion may have additional effects on cognitive and emotional development, timing of puberty and final stature. Obese children and adolescents are frequently entangled in a vicious cycle between distress, impairing self-image and distorted self-image, maintaining and worsening distress.

    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.

    To assess links between comorbid health status, severe excess weight, and weight-related quality of life (WRQOL) in adolescents with severe obesity and undergoing weight-loss surgery (WLS) to inform clinical care. Baseline (preoperative) data from Teen Longitudinal Assessment of Bariatric Surgery, a prospective multicenter observational study of 242 adolescents with severe obesity (MedianBMI = 50.5 kg/m(2); Meanage = 17.1; 75.6% female; 71.9% white) undergoing WLS, were used to examine the impact of demographics, body mass index (BMI), presence/absence of 16 comorbid conditions, and a cumulative comorbidity load (CLoad) index on WRQOL scores (Impact of Weight on Quality of Life-Kids). WRQOL was significantly lower than reference samples of healthy weight, overweight, and obese samples. Of 16 comorbid conditions, the most prevalent were dyslipidemia (74.4%), chronic pain (58.3%), and obstructive sleep apnea (56.6%). Male subjects had a greater CLoad (P = .01) and BMI (P = .01), yet less impairment in total WRQOL (P conditions (eg, stress urinary incontinence) also emerged as contributors to lower WRQOL. WRQOL impairment is substantial for adolescents with severe obesity undergoing WLS, with predictors varying by sex. These patient-data highlight targets for education, support, and adjunctive care referrals before WLS. Furthermore, they provide a comprehensive empirical base for understanding heterogeneity in adolescent WRQOL outcomes after WLS, as weight and comorbidity profiles change over time.

    Obesity has been related to deficient mental rotation performance. We assessed object-based and egocentric MR tasks in 19 obese and 19 normal-weight participants. Results showed slower response times of obese adolescents only for high angular disparities. This finding might emerge because of impairments in working memory, motor skills or perspective taking processes in obese youth. Copyright © 2016 Asia Oceania Association for the Study of Obesity.

    Objectives Obesity is considered as one of the most important public health problems of our times. The last few decades the prevalence of obesity, especially among children and adolescents, has increased dramatically worldwide. The aim of our study was to determine whether the composition of the gut microbiota is related to obesity in childhood. Methods A cross-sectional study was set-up to examine the gut microbiota using faecal samples from 22 obese children and 33 non-obese chil...

    To investigate the association between obesity and multiple sclerosis (MS) while accounting for established genetic and environmental risk factors. Participants included members of Kaiser Permanente Medical Care Plan, Northern California Region (KPNC) (1235 MS cases and 697 controls). Logistic regression models were used to estimate odds ratios (ORs) with 95% confidence intervals (95% CI). Body mass index (BMI) or body size was the primary predictor of each model. Both incident and prevalent MS cases were studied. In analyses stratified by gender, being overweight at ages 10 and 20 were associated with MS in females (pchildhood and adolescence obesity confer increased risk of MS in females beyond established heritable and environmental risk factors. Strong evidence for a dose-effect of BMI in 20s and MS was observed. The magnitude of BMI association with MS is as large as other known MS risk factors.

    Full Text Available Inactivity combined with obesity during adolescence increases the risk of future cardiovascular disease. The study purpose was to compare the influence of differing intensities of exercise on endothelial function in sedentary adolescents with obesity. Participants were randomized to one of two groups in a 6-week exercise intervention: moderate intensity (MOD or high intensity interval exercise (HIIE. Endothelial function was assessed pre- and post-intervention via fasted serum levels of endothelin-1 (ET-1. Pre-measures of ET-1 concentrations were elevated at baseline. No significant differences in ET-1 were found between or within exercise groups. However, in the HIIE group, ET-1 was inversely associated with percentages of age predicted maximal heart rate achieved during the intervention (p=0.035, r=-0.567. The exercise interventions did not positively change ET-1 levels, yet participants who exercised at higher intensities in the HIIE group experienced greater decreases in ET-1.

    Infertility affects approximately one in six couples during their lifetime. Obesity affects approximately half of the general population and is thus a common problem among the fertile population. Obese women have a higher prevalence of infertility compared with their lean counterparts. The majority of women with an ovulatory disorder contributing to their infertility have polycystic ovary syndrome (PCOS) and a significant proportion of women with PCOS are obese. Ovulation disorders and obesity-associated infertility represent a group of infertile couples that are relatively simple to treat. Maternal morbidity, mortality and fetal anomalies are increased with obesity and the success of assisted reproductive technology (ART) treatments is significantly reduced for obese women. Body mass index (BMI) treatment limits for ART throughout the UK vary. The mainstay for treatment is weight loss, which improves both natural fertility and conception rates with ART. The most cost-effective treatment strategy for obese infertile women is weight reduction with a hypo-caloric diet. Assisted reproduction is preferable in women with a BMI of 30 kg/m(2) or less and weight loss strategies should be employed within primary care to achieve that goal prior to referral.

    Objective. To understand the relationships between participation in different types of leisure time sport activity and adolescent obesity, and how those relationships might differ based on race, gender, and household income. Methods. Data consisted of 6667 students that took part in the 1999 to 2006 National Health and Nutrition Examination Survey. The authors used adjusted Wald tests to examine differences in the prevalence of obesity (body mass index >95th percentile for age and sex) by sport for boys and girls separately. Results. Among adolescent youth age 12 to 19 years, 16.6% of male leisure time sport participants and 15.3% of female sport participants were obese, compared with 23.6% for male nonathlete participant-in-other-activities and 17.0% obesity rate for female nonathlete/participant-in-other-activities. For both males and females, reported participation in leisure time sports decreased between middle school and high school, and this reduction was associated with higher body mass index.

    Cultural differences in ideal body weight are well established, but less research has examined attraction toward potential mates of heavier body weights. We examined whether exposure to obesity increases physical attraction toward overweight men. In Studies 1 and 2, we examined the effect that exposure to obese vs healthy weight men had on female attraction toward an overweight man. Study 3 examined whether females who are regularly exposed to males of heavier body weights reported a greater attraction toward overweight men. Study 4 tested whether females in an online dating study were more likely to choose to date an overweight man, after having been exposed to obesity. Exposure to obesity altered visual perceptions of what normal and therefore healthy body weights were and this resulted in greater attraction toward an overweight man (Studies 1 and 2). Females regularly exposed to men of heavier body weight reported a greater attraction toward overweight men (Study 3). After exposure to obesity, females in an online dating study were more likely to choose to date an overweight man ahead of a healthy weight man (Study 4). Exposure to male obesity increases female attraction toward overweight men and may affect mate choice.

    To evaluate the impact of contamination, or the presence of child maltreatment in a comparison condition, when estimating the broad, longitudinal effects of child maltreatment on female health at the transition to adulthood. The Female Adolescent Development Study (N = 514; age range: 14-19 years) used a prospective cohort design to examine the effects of substantiated child maltreatment on teenage births, obesity, major depression, and past-month cigarette use. Contamination was controlled via a multimethod strategy that used both adolescent self-report and Child Protective Services records to remove cases of child maltreatment from the comparison condition. Substantiated child maltreatment significantly predicted each outcome, relative risks = 1.47-2.95, 95% confidence intervals: 1.03-7.06, with increases in corresponding effect size magnitudes, only when contamination was controlled using the multimethod strategy. Contamination truncates risk estimates of child maltreatment and controlling it can strengthen overall conclusions about the effects of child maltreatment on female health. © The Author 2015.

    The objective of the study was to provide current estimates of the prevalence and trends of overweight and obesity (OW+OB) in Mexican children and adolescents. Body mass index objectively measured was analyzed for 37 147 children and adolescents aged 0-19 years obtained in 2012 as part of the National Health and Nutrition Survey (ENSANUT-2012), a nationally representative sample of the Mexican population. In addition, data from previous National Nutrition Surveys obtained in 1988, 1999 and 2006 were compared with analyze trends over a 24-year period (1988-2012) for children children. World Health Organization Child Growth Standard was used to define OW+OB. In 2012, 33.5% of children overweight or were overweight (OW); 32% and 36.9% of girls and boys 5-11 years of age were OW+OB, respectively, and 35.8% and 34.1% of female and male adolescents were OW+OB, respectively. Statistically significant trends were documented for all age groups during the study period. Overall change in the combined prevalence in preschool children was 6.3±1.0 percentage points (pp; Pchildren and adolescents in the lowest quintile of the household living condition index. Prevalence of OW+OB among children and adolescents increased significantly during the last 13-24 years. The rate of increase has declined in the last 6 years in all age groups. Changes in prevalence of OW+OB presented here suggest that, in Mexico, the burden of obesity is shifting toward the groups with lower socioeconomic level.

    Identification of children at risk for adolescent overweight can assist in targeting interventions. Uncertainty remains regarding the validity of current body mass index (BMI) reference values in predicting future risk on a population basis. This study aimed to assess the validity of current childhood adiposity classifications in predicting adolescent overweight and obesity among Israeli youth. Historical cohort study. School-based childhood health studies and adolescent physical examinations. A total of 3 163 subjects surveyed first at age 8-15 and again at age 17-19. Age, sex, height, weight and BMI. Sensitivity, specificity, positive and negative predictive values, and relative risk of childhood adiposity classification. Childhood overweight and obesity showed low sensitivity and high specificity for predicting adolescent overweight and obesity. Positive predictive values were low and varied by age and sex, but negative predictive values were consistently high in both sexes and all ages (range 0.85-0.99). After adjusting for age and sex, both childhood overweight and obesity substantially increased the risk of adolescent overweight (relative risk [RR] 7.03 and 7.20, respectively) and adolescent obesity (RR 24.34 and 28.41, respectively). Childhood overweight and obesity are strong risk factors for adolescent overweight and obesity among Israeli youth. Normal weight children were at very low risk for adolescent overweight. These findings suggest that population-based health promotion aimed at maintaining normal weight among children should be given preference over risk-guided approaches targeting weight reduction among obese children.

    Sexual minority girls (lesbian/bisexual) and girls with overweight/obesity experience high rates of discrimination and mental distress. This study explored whether BMI or perceived weight status might compound sexual minority girls' risk for harassment and mental distress. Data on female students from the national 2015 Youth Risk Behavior Survey (n = 7,006) were analyzed. Logistic regression was used to examine differences in bullying, harassment, and mental distress across sexual identity/BMI groups: heterosexual/normal-weight, heterosexual/overweight, sexual minority/normal-weight, and sexual minority/overweight. Procedures were repeated with four analogous groups created from sexual identity and perceived weight. Across sexual identity/BMI groups, being overweight increased heterosexual females' odds of being bullied or experiencing suicidal thoughts and behaviors. Regardless of weight status, sexual minority females had greater odds for each outcome than heterosexual females. Sexual minority females who perceived themselves as overweight had greater odds of suicidality than all other sexual minority/perceived weight groups. Double jeopardy may exist for sexual minority female students who perceive themselves as overweight. Professional development with school staff on how to create a positive climate for sexual minorities and those with overweight/obesity and addressing positive identity and body image within school-based suicide prevention efforts may be important to the well-being of adolescent girls. © 2017 The Obesity Society.

    Breast FA is the most common breast tumor diagnosed in young women. Female renal transplant recipients on CsA have an increased risk of developing FA. However, reports of FA after LDLT have not been described. Our objectives were to determine the incidence of FA, analyze risk factors for FA, and evaluate treatment strategies in adolescent females after LDLT. A total of 18 female patients aged 10-19 years who underwent LDLT and survived at least one year after transplantation were enrolled in our study. The incidence of FA was 11.1%. To determine pre- or post-transplant conditions that are associated with FA after transplantation, the patients were divided into two groups according to the presence or absence of FA: FA group (n=2) and non-FA group (n=16). There were no differences in mean age at LDLT, mean age at breast evaluation, and mean duration between transplantation and breast evaluation between the two groups. However, there was a difference in the immunosuppressive regimen between the two groups. The FA group was maintained on CsA, whereas the non-FA group was maintained on tacrolimus. CsA might be implicated in FA development in adolescent females after LDLT. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Obesity is a world problem that requires a better understanding of its physiological and genetic basis, as well as the mechanisms by which the hypothalamus controls feeding behavior. The volcano mouse Neotomodon alstoni develops obesity in captivity when fed with regular chow diet, providing a novel model for the study of obesity. Females develop obesity more often than males; therefore, in this study, we analysed in females, in proestrous lean and obese, the differences in hypothalamus expression of receptors for leptin, ghrelin (growth hormone secretagogue receptor GHS-R), and VPAC, and correlates for plasma levels of total ghrelin. The main comparisons are between mice fed ad libitum and mice after 24 hours of fasting. Mice above 65 g body weight were considered obese, based on behavioral and physiological parameters such as food intake, plasma free fatty acids, and glucose tolerance. Hypothalamic tissue from obese and lean mice was analysed by western blot. Our results indicate that after ad libitum food access, obese mice show no significant differences in hypothalamic leptin receptors, but a significant increase of 60% in the GHS-R, and a nearly 62% decrease in VPAC2 was noted. After a 24-hour fast, plasma ghrelin increased nearly two fold in both lean and obese mice; increases of hypothalamic leptin receptors and GHS-R were also noted, while VPAC2 did not change significantly; levels of plasma free fatty acids were 50% less after fasting in obese than in lean animals. Our results indicate that in obese N. alstoni mice, the levels of orexigenic receptors in the hypothalamus correlate with overfeeding, and the fact that lean and obese females respond in different ways to a metabolic demand such as a 24-hour fast.

    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.

    Our aim was to evaluate bidirectional associations of obesity and depression in cross-sectional and longitudinal studies with initial assessments in childhood or adolescence. The clarification of these relationships may support the development of innovative interventions, e.g. based on nutrition and mental health. A systematic literature search was conducted in MEDLINE. Main inclusion criteria were (i) assessment of subjects obesity and depression. Three out of eight longitudinal studies reported associations between obesity and subsequent depression in female children and adolescents only, and three out of nine studies obtained evidence in favour of the other direction with two studies revealing significant results only for female and one only for male children and adolescents. Evidence is mixed, and secure conclusions are hampered by the methodological variance of the included studies. Relationships are seemingly more readily detectable in female children adolescents and in the cross-sectional compared with the longitudinal analyses. Possibly, the joint development of obesity and depression in predisposed subjects accounts for the latter discrepancy. © 2015 World Obesity.

    Early adolescence is a time when a transition away from sport and physical activity participation is at its highest level among female youth (Hedstrom & Gould, 2004). This has led to the identification of barriers and facilitators of physical activity participation for adolescent females. Consequently there have been calls to overcome barriers and augment facilitators via the creation of gender-relevant programming. Despite these calls and efforts, a gender disparity remains, and a detailed understanding of how girls experience and interpret physical activity within the context of their lives is still lacking. The current project aimed to gain further insight into the foregoing using tenets of Interpretive Phenomenology to further understand the lived physical activity experiences of females during early adolescence, delineating their barriers to participation and the factors enabling participation. Five themes were identified and made into vignettes to facilitate understanding from adolescent females' perspectives: friends or don't know anyone, good or not good enough, fun or not fun; good feeling or gross; and peer support or peer pressure. The physical activity promotion implications for female youth are discussed within the context of these themes.

    Rates of venous thromboembolism have increased in the adolescent population over the last two decades, likely due to advanced diagnostics, increased use of central venous catheters, chronic medical conditions, obesity, and oral contraceptive use. Of these factors, a modifiable risk factor for adolescents is obesity. Sedentary lifestyle and prolonged immobilization are additional prothrombotic risk factors that are often associated with obesity. With ever-increasing screen time, sedentary behavior has risen accordingly, especially among gamers. We present four cases of adolescents who developed life-threatening venous thromboembolic events in the setting of obesity, sedentary lifestyle and/or immobilization, and prolonged video game use. © 2018 Wiley Periodicals, Inc.

    To examine the prevalence of overweight and obesity in Polish adolescents in 2005 using both the International Obesity Task Force (IOTF) cut-offs and a national reference; to compare this to data collected in 1995; and to assess whether there were differences in overweight or obesity by gender and place of residence in 1995-2005. BMI was calculated from measured height and weight, collected in a cross-sectional study in five regions of Poland in 2005. Adolescents were categorised as normal, overweight or obese based on IOTF cut-off values, and by national weight for stature tables, where the 90th and 97th percentiles were used as cut-off values for overweight and obesity. Population-based study set in Poland. A two-stage sampling method was used to recruit 8065 pupils (3980 boys and 4085 girls) aged 13-15 years. The prevalence of overweight and obesity was 12·5 % and 1·9 %, respectively. No significant gender differences were found, either in overweight or obesity. The prevalence of overweight and obesity in 2005 had increased 2 % compared to 1995. Overweight and obesity among adolescents were not related to urban-rural residence, but there were significant regional differences. Monitoring trends in overweight and obesity among adolescents in all regions of Poland using the same reference criteria is important. Since regional differences in overweight and obesity rates among adolescents were observed both in 1995 and 2005, future research should investigate the potential causes of these differences.

  18. Adolescent female sex workers: invisibility, violence and HIV.

    A large number of female sex workers are children. Multiple studies demonstrate that up to 40% of women in prostitution started this work prior to age 18. In studies across India, Nepal, Thailand and Canada, young age at entry to sex work has been found to heighten vulnerability to physical and sexual violence victimisation in the context of prostitution, and relates to a two to fourfold increase in HIV infection. Although HIV risk reduction among adult female sex workers has been a major focus of HIV prevention efforts across the globe, no public health interventions, to date, have addressed the increased hazards and HIV risk faced by adolescent female sex workers. Beyond the structural barriers that limit access to this vulnerable group, historical tensions between HIV prevention and child protection agencies must be overcome in order to develop effective strategies to address this large scale yet little recognised human rights and HIV-related crisis.

    Full Text Available Overweight and obesity in children and adolescents are on the increase worldwide.Overweight and obesity increase the risk for the development of non-communicable diseases during childhood and adolescence, and predispose the individual to the development of overweight, obesity,ardiovascular disease, and metabolic and other disorders in adulthood.In Africa the number of overweight or obese children has doubled since 1990. In South Africa,overweight and obesity in children and adolescents are on the increase, but the prevalencevaries with age, gender and population group. These differences are important when intervention programmes and policies are considered. South Africa faces a double burden of disease where undernutrition and overweight or obesity are found in the same populations, in the same households and even in the same children. Malnutrition is a major contributor to the double burden of disease in South African children and adolescents.

    Exercise stimulates the production of fibronectin type III domain-containing protein 5 (FNDC5), which is cleaved to release a protein called irisin. This protein induces browning of white adipose tissue resulting in increased thermogenesis. Different studies have measured circulating irisin at baseline and in response to exercise among a wide variety of individuals; yet, regarding the effect of different exercise intensities in obese adolescent girls, limited insight is available. This study compares the effect of acute aerobic exercise of moderate intensity and high-intensity interval training (HIIT) on irisin levels in skeletal muscle and plasma of sedentary overweight or obese female adolescents. The aerobic group (n = 15) and HIIT group (n = 15) underwent anthropometric and metabolic measurements, electrocardiogram, peak oxygen uptake (VO 2peak ), and two vastus lateralis muscle biopsies before and after session of workout. The session of aerobic exercise included cycling at 65% of their peak heart rate (HRpeak) for 40 min. In the HIIT group, exercise included six bouts of 1 min at 85-95% HRpeak separated by 1 min of recovery. Irisin levels were evaluated in samples of skeletal muscle (western blot) and plasma (ELISA). The levels of expression of irisin in skeletal muscle increased significantly after a session of HIIT (p HIIT session. No increases in plasma irisin concentration were observed.

    The increasing prevalence of childhood obesity is - amongst other factors - due to changed leisure time habits with decreased physical activity and increased media consumption. However, electronic media such as tablets and smartphones might also provide a novel intervention approach to prevent obesity in childhood and adolescence. A summary of interventions applying electronic media to prevent childhood obesity is provided to investigate short term effects as well as long term results of these interventions. A systematic literature search was performed in PubMed/Web of Science to identify randomized and/or controlled studies that have investigated the efficacy of electronic media for obesity prevention below the age of 18. A total of 909 studies were identified, and 88 studies were included in the analysis. Active video games did increase physical activity compared to inactive games when applied within a peer group. Interventions via telephone had positive effects on certain lifestyle-relevant behaviours. Interventions via mobile were shown to decrease dropout rates by sending regular SMS messages. To date, interventions via smartphones are scarce for adolescents; however, they might improve cardiorespiratory fitness. The results from internet-based interventions showed a trend towards positive effects on lifestyle-relevant behaviors. The combination of different electronic media did not show superior results compared to interventions with only one medium. Interventions via TV, DVD or video-based interventions may increase physical activity when offered as an incentive, however, effects on weight status were not observed. Children and adolescents currently grow up in a technology- and media-rich society with computers, tablets, smartphones, etc. used daily. Thus, interventions applying electronic media to prevent childhood obesity are contemporary. Available studies applying electronic media are however heterogeneous in terms of applied medium and duration

    Obesity impacts the physical and psychological health of children and adolescents, and is a risk factor for development of episodic and chronic illness. Rural Mexican-American adolescents are at risk for obesity and associated chronic illnesses.The study used a retrospective chart review of data collected routinely in a rural health clinic setting from 1 January 2005 to 31 December 2010 to assess incidence of overweight/obesity status and episodic or chronic illness among Mexican-American adolescents aged 12-18 years. Analyses included body mass index, age, gender, and episodic or chronic illness diagnoses. Two hundred twelve charts were audited; women (n = 114, 53.8%), men (n = 98 46.2%); normal (n = 105, 49.5%), overweight/obese (n = 107, 50.5%). There were more female normal (n = 61, 53.5%) vs. overweight/obese (n = 53, 46.5%). More male overweight/obese (n = 54, 55.1%) than normal weight (n = 44, 44.9%). Age at first documented overweight/obesity status occurred in early adolescence (median = 13 years, mode = 12 years). Chronic illness incidence was higher among men than women, and overweight/obese vs. normal weight adolescents and in sub-categorizations by weight and specific illness. Incidence of episodic illness was higher among women than men, with variation by weight and specific illness. Disproportionately high incidence of episodic or chronic illness and overweight/obesity identified among rural Mexican-American adolescents compels intervention modification to improve effectiveness. © 2014 Wiley Publishing Asia Pty Ltd.

    This study determined whether female adolescents who were attempting weight loss (dieters) differ from those who were not (nondieters) with respect to a set of psychosocial factors. The sample consisted of 2,536 normal-weight and underweight female adolescents who participated in the National Longitudinal Adolescent Health Survey. Psychosocial factors examined included depression (four measures), self-esteem, trouble in school, school connectedness, family connectedness, sense of community (two measures), grades, autonomy, and protective factors. MANCOVA revealed significant differences between dieters and nondieters. Self-esteem was the strongest contributing factor differentiating dieters and nondieters. These results have implications for health education and health promotion with regard to both primary and secondary prevention. Self-esteem building should be incorporated within the parameters of a comprehensive school health program and certainly should be a component in any nutrition education program aimed at preventing unhealthy dieting behaviors. By understanding the factors associated with these behaviors, it may be easier to identify individuals attempting weight loss despite being of normal or low body weight.

    This study aims to investigate whether experiences of offline sexual coercion are associated with adolescent females' involvement in different types of sexting behaviors. It draws on data from 450 ethnically diverse female adolescents with an average age of 19.02 years (SD = 0.74) who were originally recruited in southeast Texas. The participants were asked about their experiences with sexual coercion, and their engagement in sexting behavior (i.e., sending, requesting, and being asked for a sext, and receiving a sext without giving permission). Logistic regressions were used to analyze these relationships, while controlling for age, ethnicity, education level, living situation, and sexting behaviors in the year prior of the study. Offline sexual coercion was significantly associated with sending and being asked for a naked image, as well as receiving a naked image without giving permission. The results suggest that sexting could function as an online extension of offline forms of sexual coercion. Copyright © 2016 The Foundation for Professionals in Services for Adolescents.

    Full Text Available Objective: To evaluate the inappropriate eating behaviors (IEB of female adolescents over a one-year period. Methods: 290 adolescents aged between 11 and 14 years old participated in the three research stages (T1: first four months, T2: second four months and T3: third four months. The Eating Attitudes Test (EAT-26 was applied to assess the IEB. Weight and height were measured to calculate body mass index (BMI in the three study periods. Analysis of variance for repeated measures was used to analyze the data, adjusted for the scores of the Body Shape Questionnaire and the Brazil Economic Classification Criteria. Results: Girls at T1 showed a higher frequency of IEB compared to T2 (p=0.001 and T3 (p=0.001. The findings also indicated higher values for BMI in T3 in relation to T1 (p=0.04. The other comparisons did not show statistically significant differences. Conclusions: IEB scores of female adolescents declined over one year.

    To determine the prevalence of substance use in adolescents with eating disorders, compare the results with a data set of Ontario high school students, and explore why adolescents with eating disorders do, or do not, use various substances. From January 1999 to March 2000, 101 female adolescents who met the DSM-IV criteria for an eating disorder were followed up in a tertiary care pediatric treatment center. They were asked to participate in a cross-sectional study using a self-administered questionnaire assessing substance use and investigating reasons for use and nonuse; 95 agreed to participate and 77 completed the questionnaire (mean age, 15.2 years). The patients were divided into two groups: 63 with restrictive symptoms only, 17 with purging symptoms. The rates of drug use between subjects and their comparison groups were compared by z-scores, with the level of significance set at.05. During the preceding year, restrictors used significantly less tobacco, alcohol, and cannabis than grade- and sex-matched comparison populations, and purgers used these substances at rates similar to those of comparison subjects. Other drugs seen frequently in the purgers included hallucinogens, tranquilizers, stimulants, LSD, PCP, cocaine, and "ecstasy." Both groups used caffeine and laxatives, but few used diet pills. Restrictors said they did not use substances because they were bad for their health, tasted unpleasant, were contrary to their beliefs, and were too expensive. Purgers generally used substances to relax, relieve anger, avoid eating, and "get away" from problems. Female adolescents with eating disorders who have restrictive symptoms use substances less frequently than the general adolescent population but do not abstain from their use. Those with purging symptoms use substances with a similar frequency to that found in the general adolescent population. Because the sample size for the purging group was small, firm conclusions cannot be drawn from our analysis

    We conducted a cross-sectional study among 1,717 children and adolescents of Mexican origin ages 5-19 years living in Mexico and Texas to explore the influence of country of birth and country of longest residence on their overweight and obesity status. Descriptive statistics were used to compare demographic and anthropometric characteristics of participants born and raised in Mexico (Mexicans), born in Mexico and raised in the United States (Mexican immigrants), and born and raised in the United States (Mexican-Americans). Univariate and multivariate nominal logistic regression was used to determine the demographic predictors of obesity adjusted by country of birth, country of residence, age, and gender. Almost half (48.8%) of the Mexican-Americans and 43.2% of the Mexican immigrants had body mass index at the 85th percentile or above, compared to only 29.3% of the Mexicans (P obese than their Mexican peers [Mexican-Americans: odds ratio (OR) = 2.5 (95% confidence interval [CI] 1.8-3.4); Mexican immigrants: OR = 2.2 (95% CI 1.6-3.0)]. In addition, males were more likely than females to be obese [OR = 1.6 (95% CI 1.2-2.1)], and adolescents 15-19 years of age were less likely than their younger counterparts [OR = 0.5 (95% CI 0.4-0.7)] to be obese. The high prevalence of obesity among children of Mexican origin in the United States is of great concern and underscores the urgent need to develop and implement obesity preventive interventions targeting younger children of Mexican origin, especially newly arrived immigrant children. In addition, future obesity research should take into consideration the country of origin of the study population to develop more culturally specific obesity interventions.

    Full Text Available Besides other explanatory variables, parenting styles and parental violence might also be responsible for setting a path towards overweight/obesity in childhood. While this association has consistently been observed for adults, findings for adolescents still remain scarce and inconsistent. Therefore, the goal of this study is to add evidence on this topic for children and adolescents. Analyses are based on a sample of 1729 German, ninth-grade students. To analyze associations between parenting dimensions and weight status, non-parametric conditional inference trees were applied. Three gender-specific pathways for a heightened risk of overweight/obesity were observed: (1 female adolescents who report having experienced severe parental physical abuse and medium/high parental warmth in childhood; (2 male adolescents who report having experienced low or medium parental monitoring in childhood; and (3 this second pathway for male adolescents is more pronounced if the families receive welfare. The importance of promoting parenting styles characterized by warmth and a lack of physical abuse is also discussed. This is one of only a few studies examining the association of parenting dimensions/parental physical abuse and weight status in adolescence. Future studies should include even more parenting dimensions, as well as parental physical abuse levels, in order to detect and untangle gender-specific effects on weight status.

    HDL regulates endothelial function via stimulation of nitric oxide production. It is documented that endothelial function is impaired in obese adolescents, and improved by lifestyle interventions (LI). HDL function in obese adolescents and the impact of LI or Roux-en-Y gastric bypass surgery (RYGB) was assessed. HDL was isolated from 14 adolescents with normal body mass index (HDLcontrol ), 10 obese (HDLobese ) before and after 6 month LI, and five severe obese adolescents before and one year after RYGB. HDL-mediated phosphorylation of endothelial nitric oxide synthase (eNOS)-Ser(1177) , eNOS-Thr(495) , and PKC-ßII was evaluated. In addition the HDL proteome was analyzed. HDLobese -mediated eNOS-Ser(1177) phosphorylation was reduced, whereas eNOS-Thr(495) phosphorylation increased significantly when compared to HDLcontrol . No impact of obesity was observed on PKC-ßII phosphorylation. LI and RYGB had no impact on HDL-mediated phosphorylation of eNOS and PKC-ßII. A principle component plot analysis of the HDL particle separated controls and severe obese, whereas the interventions did not trigger sufficient differences to the HDL proteome to permit distinction. These results demonstrated that HDL-function is impaired in obese adolescents, and that LI or RYGB did not correct this dysfunction. This might be an argument for developing earlier prevention strategies in obese adolescents to avoid HDL dysfunction. Copyright © 2013 The Obesity Society.

    We aimed to determine the risk factors associated with abdominal obesity (AO) in suburban adolescents. This cross-sectional study included adolescents aged 15-17 years from five randomly selected secondary schools in the Hulu Langat district of Selangor state, Malaysia. Waist circumference (WC) was measured at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest. Information on sociodemographic data, dietary habits, physical activity levels and duration of sleep was obtained via interviewer-administered questionnaires. Participants' habitual food intake was determined using a 73-item Food Frequency Questionnaire. Among 832 participants, 56.0% were girls; 48.4% were Malay, 40.5% Chinese, 10.2% Indian and 0.8% of other ethnic groups. Median age and WC were 16 (interquartile range [IQR] 15-16) years and 67.9 (IQR 63.0-74.6) cm, respectively. Overall prevalence of AO (> 90th percentile on the WC chart) was 11.3%. A higher proportion (22.4%) of Indian adolescents were found to have AO compared with Malay and Chinese adolescents. Logistic regression analysis showed that female gender (adjusted odds ratio [OR] 7.064, 95% confidence interval [CI] 2.087-23.913; p = 0.002), Indian ethnicity (adjusted OR 10.164, 95% CI 2.182-47.346; p = 0.003), irregular meals (adjusted OR 3.193, 95% CI 1.043-9.774; p = 0.042) and increasing body mass index (BMI) (adjusted OR 2.867, 95% CI 2.216-3.710; p < 0.001) were significantly associated with AO. AO was common among Malaysian adolescents. Female gender, Indian ethnicity, irregular meals and increasing BMI were significant risk factors. Copyright: © Singapore Medical Association.

Longitudinal analysis of participants from the US National Longitudinal Study of Adolescent Health (n = 10,774) wave II (1996; aged 12-22 years) followed through wave IV (2008-2009; aged 24-34 years). New cases of adult-onset severe obesity (body mass index [BMI] ≥ 40 kg/m2 using measured height and weight) in individuals followed over 13 years who were not severely obese during adolescence (BMI childhood was associated with an increased risk of incident severe obesity in adulthood in non-minority females (hazard ratio [HR; 95% Confidence Interval] = 2.5; 1.3, 4.8) and males (HR = 3.6; 1.5, 8.5) compared with individuals with no history of abuse. In addition to other social and emotional risks, exposure to sexual and physical abuse during childhood may increase risk of severe obesity later in life. Consideration of the confluence of childhood abuse might be considered as part of preventive and therapeutic approaches to address severe obesity. © 2013 The Authors.

    Full Text Available Objective: Altered gastrointestinal function has frequently been observed in obese patients. The aim of this study was to investigate the frequency of gastro-esophageal reflux (GER and to determine the alterations of gastric emptying and esophageal transit by scintigraphic methods in obese patients. Methods: Scintigraphic studies of 50 obese female non-diabetic patients who had not received any treatment for weight control were retrospectively reviewed. Mean Body Mass Index (BMI was 34.96±3.04 kg/m² (range:32-39 kg/m². All subjects were submitted to scintigraphic evaluation of esophageal transit, gastro-esophageal reflux, gastric emptying and presence of Helicobacter pylori infection. The data of obese patients were compared with those of sex-age matched 30 non-obese cases who were selected from our clinical archive. Results: In obese group, seventeen (34% patients were found to be GER positive scintigraphically; mean gastric emptying time (t½ was 59.18±30.8 min and the mean esophageal transit time was 8.9±7.2 s. Frequency of positive GER scintigraphy and the mean value of esophageal transit time were significantly higher in obese patients than non-obese control subjects. Gastric emptying time and esophageal transit time values were significantly longer in GER positive obese patients than GER negative ones. There was no statistically significant difference in the frequency of positive C14 urea breath test between obese and non-obese subjects and there were also no statistically significant correlations between BMI, GER, esophageal transit time and gastric emptying time. Conclusion: In our study, 42 of the 50 obese patients had esophago-gastric motility alterations. The significance of these alterations in obesity is not fully understood, but it is believed that these changes could be because of potential contributing factors in the development or maintenance of obesity or changes in eating habits

    Rates of adult women receiving contraceptive provision when simultaneously prescribed a known teratogen are alarmingly low. The prevalence of this behavior among pediatric providers and their adolescent patients is unknown. The objective of this study was to describe pediatric provider behaviors for prescribing teratogens concurrently with counseling, referral, and/or prescribing of contraception (collectively called contraceptive provision) in the adolescent population. A retrospective review was conducted examining visits in 2008-2012 by adolescents aged 14 to 25 years in which a known teratogen (US Food and Drug Administration pregnancy risk category D or X) was prescribed. The electronic medical records were queried for demographic information, evidence of contraceptive provision, and menstrual and sexual histories. The data were analyzed using standard statistical methods. Within 4172 clinic visits, 1694 females received 4506 prescriptions for teratogenic medications. The most commonly prescribed teratogens were topiramate, methotrexate, diazepam, isotretinoin, and enalapril. The subspecialties prescribing teratogens most frequently were neurology, hematology-oncology, and dermatology. Overall, contraceptive provision was documented in 28.6% of the visits. Whites versus nonwhites and older versus younger girls were more likely to receive contraceptive provision. The presence of a federal risk mitigation system for the teratogen also increased the likelihood of contraceptive provision. Our data demonstrate female adolescents prescribed teratogens receive inadequate contraception provision, which could increase their risk for negative pregnancy outcomes. Although the presence of a federal risk mitigation system appears to improve contraceptive provision, these systems are costly and, in some instances, difficult to implement. Efforts to improve provider practices are needed. Copyright © 2016 by the American Academy of Pediatrics.

    Full Text Available Background: Currently, there is a well-publicised worldwide increase in obese patients. The origins of adult obesity, in the majority of cases, are in children. Objective: Our aim was to study the prevalence and gender features of excess weight and obesity in adolescents in Perm. Methods: The study included adolescents aged 13–14, living in the city of Perm. Medical examinations were compared in statistics from 2005 and 2013. Weight, height and waist circumference were measured on all children. Body mass index was calculated, as was a standard deviation coefficient. Sexual development was evaluated according to the criteria of Tanner. Results: 828 adolescents were viewed (444 in 2005 and 384 in 2013. The prevalence of overweight adolescents in 2005 was 12.5%, including 3.1% who were obese. In 2013, 20.3% of adolescents were diagnosed as overweight, with 5.5% being diagnosed as obese. Abdominal obesity to type was diagnosed in 52.4% of obese children. Over the past 8 years, the number of adolescents who are overweight and obese has increased by more than half. A statistically significant increase has beenrecorded for overweight adolescents (ᵪ2 = 5,16; p = 0,023. In adolescents with excess body weight, growth rates were higher than in those children with either normal body weight or obesity; these differences were statistically significant in boys (p = 0.016. The total score of puberty in boys who were overweight was statistically significantly higher than adolescents with normal body weight orobesity (p = 0.0116. Conclusion: The percentage of children who are overweight and obese hasincreased by 74% and 67%, respectively over an 8-year period, resulting ina statistically significant increase in relation to overweight children. There was a significant increase in the number of teenage girls who are overweight.

    Physical activity and sport can influence the extent of the presence of the postural disturbances in children. The aim of this study was to investigate the occurrence of differences in the postural disturbances in female adolescents in relation to team handball training. This investigation involved 150 female adolescents with the average age of 13.4 ± 1.5 years divided into two groups (50 adolescents trained handball and 100 did non train it). The study determined a statistically significant difference in the total number of postural disturbances between the two groups of adolescents (p 0.05). Handball adolescents players have less postural disturbances than untrained adolescents. Flat foot is significantly less frequent in female adolescents handball players than in untrained ones. Findings obtained in this investigation can help us in planning continuous prevention, observation and care for untrained and trained team handball female adolescents with postural disturbances.

    Placement into foster care is driven by a number of factors, many of which are associated with adolescent childbirth. Yet, there are few studies that identify the experiences and characteristics that predict adolescent childbirth among girls who spend time in foster care. A longitudinal, population-based data set was constructed by probabilistically matching California child protective service records for female foster youth to maternal information available on vital birth records for children born between 2001 and 2010. Rates of childbirth among girls in foster care after their 10th birthday were generated. Chi-square tests assessed differences and survival models were specified to determine the rate of childbearing across key characteristics. Among the 30,339 girls who spent time in foster care as adolescents, 18.3% (5,567) gave birth for the first time before their 20th birthday. At a bivariate level, significant differences (p foster care placement experiences. In the fully adjusted survival model, the highest birth rates were observed among girls who entered care between ages 13 and 16 years; had been in care for relatively short periods of time; lived in congregate care at the estimated date of conception; had a history of running away; and were Latina, black, or Native American. The results suggest that there are identifiable risk factors associated with early childbirth among girls in foster care, which can help determine the timing and location of reproductive health services to minimize unintended pregnancy and maximize adolescent health and well-being.

    To examine the effect of childhood trauma and family history of psychiatric illness on weight loss trajectories of obese, female adolescents with polycystic ovary syndrome (PCOS). Prospective study. PCOS and adolescent medicine outpatient clinics. Participants were, on average, 15.8 years of age, 80% Caucasian (39/49 participants), and had a body mass index of 36.8 ± 8.8. Healthy Bodies, Healthy Minds is an evidence-based one-on-one intervention consisting of 4 weekly sessions, 4 biweekly sessions, and 3 monthly booster sessions. Each session was 45-60 minutes long with 15-30 minutes of physical activity with a lifestyle coach. Paired sample t tests were used to assess group differences in pre- and post-treatment weight between participants reporting childhood trauma and body mass index-matched controls not endorsing trauma. One-way analysis of variance was performed to assess the influence of childhood trauma on weight loss between the 2 groups. Adolescents without a family history of psychiatric illness lost more weight (mean, -1.28 kg; SD, 6.89) than those who had a family history of psychiatric illness (mean, -0.64 kg; SD, 4.7) from baseline to booster session completion (6 months). However, results of independent t tests did not reveal statistically significant group differences in weight loss from baseline to booster session completion (t 21  = 0.51; P = .6). Obese adolescents with PCOS who have experienced childhood trauma can lose weight and acquire its health benefits when enrolled in an intervention addressing weight, mood, and sleep. Family history of psychiatric illness emerged as a potential predictor of lesser weight loss. Copyright © 2018. Published by Elsevier Inc.

    Studies exploring the effect of television viewing on obesity throughout childhood are conflicting. Most studies have been confined to single high-income countries. Our aim was to examine the association between television viewing habits and Body Mass Index (BMI) in adolescents and children in a multicentre worldwide sample. In the International Study of Asthma and Allergies in Children Phase Three, adolescents aged between 12 and 15 years completed questionnaires which included questions on television viewing habits, height and weight. Parents/guardians of children aged between 5 and 8 years completed the same questionnaire on behalf of their children. The questionnaire asked "During a normal week, how many hours a day (24 hours) do you (does your child) watch television?" Responses were categorised as; "short" (5 hours). 207,672 adolescents from 37 countries and 77,003 children from 18 countries provided data. Daily television viewing in excess of one hour was reported in 89% of adolescents and 79% of children. Compared with adolescents in the short viewing group, those in the moderate, long and prolonged groups had BMIs that were 0.14 kg/m(2), 0.21 kg/m(2), 0.30 kg/m(2) and 0.08 kg/m(2), 0.16 kg/m(2) and 0.17 kg/m(2) larger for females and males respectively (both Ptelevision viewing hours were positively associated with BMI in both adolescents and children with an apparent dose response effect. These findings extend the evidence that television viewing contributes to increased BMI in childhood.

    Full Text Available Aim: There has been an explosive growth of internet usage worldwide and this is expected to continue with its use becoming an integral part of everyday life. The internet provides tremendous educational benefits; however, excessive internet use can lead to negative outcomes such as psychopathological symptoms and obesity. The aim of the study was to study association with the prevalence of internet addiction and psychopathological symptoms and obesity in adolescent age group. Methods: A total of 1175 high school students from three high schools in Giresun City were surveyed using Internet Addiction Test, Dukes Health Profile. The Data was collected using a structured questionnaire including sociodemographic characteristics. Results: Of the 1,175 adolescents who took part in the study, 588 (50.0% were female and 587 (50.0% were males. The mean age of adolescents was 15.72 +/- 1.14 years. The prevalence rate of problematic internet use was 7.1% among adolescent internet users. Those with excessive use internet had high scores on anxiety, depression, and anxiety depression. A relationship between problematic internet use and obesity was not found. Conclusions: Problematic internet use is becoming a significant public health issue that requires urgent attention. Effective measures are needed to prevent the spread of this problem and interventions to prevent the effects of problematic internet use on psychosomatic symptoms and life satisfaction should be conducted as early as possible.

    Anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), and obesity are stigmatized conditions known to affect both men and women. However, little research has examined differences in stigmatization of individuals with these diagnoses or the impact of gender on stigmatization. Such perceptions may play an important role in understanding and reducing the stigma associated with weight and dysfunctional eating behaviors. This study investigated stigmatizing attitudes toward eating disorders and obesity in men and women. Participants were university undergraduates (N = 318; 73.6% female; mean age = 21.58 years, SD=3.97) who were randomly assigned to read one vignette describing a male or female target diagnosed with AN, BN, BED, or obesity. Participants then completed measures of stigma and perceived psychopathology. Measures were analyzed using a 4 (target diagnosis) x 2 (target gender) MANOVA and subsequent ANOVAs. Measures of stigma and perceived psychopathology revealed significant main effects for diagnosis (p obesity. Additionally, individuals with AN, BN, and BED were perceived as having significantly more psychological problems and impairment than individuals with obesity. Although individuals with eating disorders and obesity both face stigmatizing attitudes, bias against individuals with AN, BN, and BED may exceed stigma toward obesity in the absence of binge eating. Future research is necessary to address stigmatizing beliefs to reduce and prevent discrimination against both men and women with eating disorders and obesity. Copyright © 2016 Elsevier Ltd.

    Obesity remains a significant threat to the current and long-term health of U.S. adolescents. The authors developed county-level estimates of adolescent obesity for the contiguous U.S., and then explored the association between 23 conceptually derived area-based correlates of adolescent obesity and ecologic obesity prevalence. Multilevel small area regression methods applied to the 2007 and 2011-2012 National Survey of Children's Health produced county-level obesity prevalence estimates for children aged 10-17 years. Exploratory multivariable Bayesian regression estimated the cross-sectional association between nutrition, activity, and macrosocial characteristics of counties and states, and county-level obesity prevalence. All analyses were conducted in 2015. Adolescent obesity varies geographically with clusters of high prevalence in the Deep South and Southern Appalachian regions. Geographic disparities and clustering in observed data are largely explained by hypothesized area-based variables. In adjusted models, activity environment, but not nutrition environment variables were associated with county-level obesity prevalence. County violent crime was associated with higher obesity, whereas recreational facility density was associated with lower obesity. Measures of the macrosocial and relational domain, including community SES, community health, and social marginalization, were the strongest correlates of county-level obesity. County-level estimates of adolescent obesity demonstrate notable geographic disparities, which are largely explained by conceptually derived area-based contextual measures. This ecologic exploratory study highlights the importance of taking a multidimensional approach to understanding the social and community context in which adolescents make obesity-relevant behavioral choices.

    Objective: To study the changes of serum leptin, insulin and adiponectin levels and their relationship with BMI in females with simple obesity. Methods: Serum leptin, adiponectin and insulin levels were measured with RIA in 48 pre-obese females (BMI=23-24.9 kg/m 2 ), 40 females with simple obesity, (BMI≥25 kg/m 2 ) and 42 female controls (BMI 18-22.9 kg/m 2 ). Correlations among these variables were studied. Results: Serum leptin, insulin levels were significantly higher and serum adiponectin levels were significantly lower in both the pre-obese and obese females than those in controls. Serum leptin, insulin levels were positively correlated to BMI; Serum adiponectin levels were negatively correlated to BMI. Conclusion: Within normal range of BMI, the leptin-insulin feedback mechanism provided satisfactory self-regulation. However, with excessive BMI, this dynamic equilibrium would be disrupted. The defective equilibrium, together with the abnormal low adiponectin level, would predispose to the development of diabetes mellitus. (authors)

    Full Text Available Background: For better perception of adolescent overweight and obesity as a global public health problem, systematic collection of baseline data is urgently needed in India. Objective: A community-based study was undertaken for better perception of the prevalence and correlates of obesity in an adolescent urban community in Katihar, Bihar. Materials and Methods: A cross-sectional study was conducted among urban adolescents in the eastern part of India to find out prevalence of overweight and obesity and sociodemographic correlates by interview technique followed by clinical examination with ethical consideration. Results: Out of 400 adolescent study participants, 21% were overweight or obese. The study showed that there was a significant association between less consumption of vegetable foods, fruits, meals cooked outside the home, alcohol consumption, yoga practice, socioeconomic status, and the occurrence of overweight/obesity in the adolescents. Conclusions: We attempted to find out the prevalence and risk correlates of overweight and obesity among adolescents and found it quite alarming compared to developed countries. The urban underserved population in India has difficulty to access quality healthcare and not conscious enough to seek healthcare until critically ill. Community-based studies are required to highlight the problem of obesity among urban adolescents by a comprehensive approach.

    Eating slowly increases the postprandial responses of some anorexigenic gut hormones in healthy lean subjects. As the rate of food intake is positively associated with obesity, the aim of the study was to determine whether eating the same meal at different rates evokes different postprandial anorexigenic responses in obese adolescent and adult subjects. Eighteen obese adolescents and adults were enrolled. A test meal was consumed on two different sessions by each subject, meal duration taking either 5  min (fast feeding) or 30  min (slow feeding). Circulating levels of glucagon-like peptide 1 (GLP1), peptide YY (PYY), glucose, insulin, and triglycerides were measured over 210  min. Visual analog scales were used to evaluate the subjective feelings of hunger and satiety. fast feeding did not stimulate GLP1 release in obese adolescent and adults, whereas slow feeding increased circulating levels of GLP1 only in obese adolescents. Plasma PYY concentrations increased both in obese adolescents and in adults, irrespective of the eating rate, but slow feeding was more effective in stimulating PYY release in obese adolescents than in adults. simultaneously, slow feeding evoked a higher satiety only in obese adolescents compared with fast feeding but not in obese adults. in obese adolescents, slow feeding decreased hunger (only at 210 min). irrespective of the eating rate, postprandial responses of insulin and triglycerides were higher in obese adults than in obese adolescents. Slow feeding leads to higher concentrations of anorexigenic gut peptides and favors satiety in obese adolescents, but this physiological control of food intake is lost in obese adults.

    Obesity exacerbates the reproductive and metabolic manifestations of polycystic ovary syndrome (PCOS). The symptoms of PCOS often begin in adolescence, and the rising prevalence of peripubertal obesity has prompted concern that the prevalence and severity of adolescent PCOS is increasing in parallel. Recent data have disclosed a high prevalence of hyperandrogenemia among peripubertal adolescents with obesity, suggesting that such girls are indeed at risk for developing PCOS. Obesity may impact the risk of PCOS via insulin resistance and compensatory hyperinsulinemia, which augments ovarian/adrenal androgen production and suppresses sex hormone–binding globulin (SHBG), thereby increasing androgen bioavailability. Altered luteinizing hormone (LH) secretion plays an important role in the pathophysiology of PCOS, and although obesity is generally associated with relative reductions of LH, higher LH appears to be the best predictor of increased free testosterone among peripubertal girls with obesity. Other potential mechanisms of obesity-associated hyperandrogenemia include enhanced androgen production in an expanded fat mass and potential effects of abnormal adipokine/cytokine levels. Adolescents with PCOS are at risk for comorbidities such as metabolic syndrome and impaired glucose tolerance, and concomitant obesity compounds these risks. For all of these reasons, weight loss represents an important therapeutic target in obese adolescents with PCOS. PMID:24715515

    Because ofpoverty, the high prevalence of obesity, and the lack of adequate supports, Central Harlem's children, adolescents, and teenagers are at risk for major physiological, psychological, and social issues. This article discusses the public health concerns related to this population, especially the prevalence of obesity. This article identifies the prevalence of illness and obesity in the inner city and stipulates the causes and consequences of obesity among children, adolescents, and teenagers. In addition, it reports on the appropriate community intervention, using a coalition and a community collaborative organization that serve as models to build support for Central Harlem. A proposal is offered for reducing obesity among youths in the community. The intervention outlines a logic model that identifies a multisystemic approach at the micro and macro level for community intervention and policy initiatives to advocate for fundamental change. Further research recommendations are described to reduce the prevalence of childhood, adolescent, and teenage obesity in urban communities.

    Within the past one and half decades many efforts have been made to improve the availability and access to adolescent sexual and reproductive health services. Despite these efforts, adolescents still face a number of sexual and reproductive health problems. This paper uses data from the 2003 and 2008 Ghana Demographic and Health Surveys to examine changes in contraceptive use among sexually active female adolescents (15-19 years old). The results show that between 2003 and 2008 there was a significant increase in the current use of any contraceptive method (from 23.7% to 35.1%, p = 0.03). It also indicates a shift from modern to traditional contraceptive methods. Traditional methods recorded about 60% (7.8 percentage points) increase as compared to 5.5% (2.6 percentage points) for modern methods. Also ever use of any traditional method recorded a higher increase as compared to any modem method. There was a slight decline 7% (4.4 parentage points) in the number of non-users who intended to use contraceptives in the future. On the whole the findings indicate increasing unmet need for modern contraception due to barriers such as limited access, cost and misconceptions about the effects of contraceptives.

    Adolescents with chronic pain often report inattention and poor memory. There has been little research on cognitive function in this population. The goal of this preliminary pilot study was to examine differences in cognitive function between adolescents with chronic pain to pain-free adolescents. All participants completed baseline assessments of pain, school absences, depression, anxiety, and sleep habits. Standardized neurocognitive tests were used to examine cognitive function with a focus on working memory and attention. Recruitment from the chronic pain clinic resulted in a female sample of 13 individuals (largely reflective of the clinical population). Pain-free age-matched and sex-matched individuals (n=12) were therefore also recruited as controls. Individuals with chronic pain had significantly lower working memory scores than controls. Differences were found between groups on the most difficult selective attention task and not on tests of sustained attention, divided attention, or attentional switching. In a stepwise regression with baseline characteristics entered in the first step, pain accounted for approximately 15% of the variance in working memory and medication score counted for 49% of the variance. This pilot study is the first study to examine differences in working memory and attention between participants with chronic pain and pain-free adolescents. Our findings suggest that chronic pain may negatively affect adolescents' working memory function and highlights the risk for cognitive difficulties and problems with educational progression in addition to negative health and social effects associated with chronic pain. The study provides a starting point for more research and has the potential to direct better identification and treatment of these cognitive deficits.

    Binge-eating disorder (BED) in adults is associated with alterations in executive functions (EF) and obesity. Much less is known about these relationships in adolescents, including whether poor EF are associated with eating disorder psychopathology and/or elevated body mass index. This study examined EF in response to neutral stimuli in youth with BED. Adolescents with BED and obesity (n = 22), individually matched adolescents with obesity (n = 22), and normal weight (n = 22) completed neuropsychological tests targeting inhibition (Color-Word Interference Test), sustained attention (D2 Concentration Endurance Test), cognitive flexibility (Comprehensive Trail Making Test), and decision-making (Iowa Gambling Task). Adolescents with BED and obesity displayed significantly poorer inhibitory control compared to normal-weight adolescents. This effect persisted after controlling for the level of secondary education. However, initial differences between adolescents with obesity and normal-weight controls regarding inhibitory control and sustained attention vanished after controlling for education. The three groups did not differ regarding cognitive flexibility and decision-making. Moreover, adolescents with BED and obesity did not perform worse than adolescents with obesity on any of the neuropsychological tests. Overall, our results indicate that adolescent BED is associated with only a few alterations in general EF, specifically inhibitory control, and underline BED and educational level as confounding factors in neuropsychological research on obesity. To further delineate EF profiles of adolescents with BED, future research should focus on EF in response to disorder-related stimuli and experimental settings with high ecological validity. © 2017 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Within the Self-Determination Theory (SDT framework, the first major study aim was to investigate the SDT tenets in an obese adolescent population by examining the factor structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2 and by investigating associations between physical activity (PA and motivation in obese adolescents. The second aim was to study differences in motivation according to adolescents' educational level, since lower educated obese adolescent are a sub-risk group for lower PA levels among the obese adolescents. The third aim was to investigate whether attending a residential obesity treatment program could lead to an increase in autonomous motivation towards PA and to see if the treatment effect on motivation was different in low versus high educated youth. Methods For the first study aim, the sample comprised 177 obese adolescents at the start of a 10-month multidisciplinary residential obesity treatment program (BMI = 35.9 ± 6.0 kg/m2, 15.1 ± 1.5 years, 62% girls. A subsample of 65 adolescents (stratified by educational level were divided into low (n = 34 versus high educated (n = 31 as part of the second and third study aim. Motivation was assessed using the BREQ-2 and PA using the Flemish Physical Activity Questionnaire. Results Exploratory factor analysis showed sufficient validations with the original factor for 17 out of 19 BREQ-2 items. Significant positive correlations were found between PA and the composite score of relative autonomy (r = 0.31, p Conclusions The BREQ-2 can be used in an obese adolescent population. Higher levels of autonomous motivation towards PA were related to higher PA levels. Adolescents had increases in both autonomous and controlled forms of motivation during treatment. Special attention for lower educated adolescents during treatment is needed, as they have a lower autonomous motivation at the start of treatment and an increase in introjected

    To investigate the association between dental caries and obesity, evaluated by air displacement plethysmography, among 18-year-old adolescents from a birth cohort in the city of Pelotas, Brazil. A cross-sectional study nested in a birth cohort study was conducted in Pelotas, Brazil. A random sample of 986 18-year-old adolescents was selected. The outcome variable was the occurrence of dental caries (DMFT ≥ 1) according to clinical examination by a trained and calibrated dentist. For the exposure variable (obesity), body fat percentage was measured using air displacement plethysmography and classified as normal weight (P95). Sociodemographic and behavior variables were collected using a questionnaire. We performed multivariable Poisson regression analyses with robust variance to examine the association between dental caries and obesity. DMFT ranged from 0 to 19; mean (SD) was 2 (2.3), and median (P25-P75) was 1 (0-3). Body fat percentage ranged from 0.9 to 57.6%; mean (SD) percentage was 24.4% (11.6%), and median (P25-P75) was 25.1% (14.0-32.9%). The prevalence of dental caries was 66.5% (95% CI 63.6-69.5%), being significantly higher in female adolescents with lower maternal education, lower education, and sugar intake more than once a day. There were no differences in the probability of dental caries among individuals with normal weight, overweight, or obesity in the unadjusted model (P = 0.846) or after adjustment for sociodemographic (P = 0.864) variables. Overweight and obesity were not associated with the occurrence of dental caries in 18-year-old adolescents. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    A common T/A polymorphism (rs9939609) in the fat mass and obesity associated (FTO) gene was found associated with early-onset and severe obesity in both adults and children. However, recent observations failed to find associations of FTO with obesity. To investigate the genetic background of early obesity, we analysed the single nucleotide polymorphism (SNP) rs9939609 of FTO in 371 styrian adolescents towards degree of obesity, subcutaneous adipose tissue (SAT)-distribution determined by lipometry, early metabolic and preatherosclerotic symptoms. The percentage of AA homozygotes for the rs9939609 SNP of FTO was significantly increased in the obese adolescents.

    Full Text Available A common T/A polymorphism (rs9939609 in the fat mass and obesity associated (FTO gene was found associated with early-onset and severe obesity in both adults and children. However, recent observations failed to find associations of FTO with obesity. To investigate the genetic background of early obesity, we analysed the single nucleotide polymorphism (SNP rs9939609 of FTO in 371 styrian adolescents towards degree of obesity, subcutaneous adipose tissue (SAT-distribution determined by lipometry, early metabolic and preatherosclerotic symptoms. The percentage of AA homozygotes for the rs9939609 SNP of FTO was significantly increased in the obese adolescents. Compared to the TT wildtype, AA homozygotes showed significantly elevated values of SAT thickness at the trunk-located lipometer measure points neck and frontal chest, body weight, body mass index, waist, and hip circumference. No associations were found with carotis communis intima media thickness, systolic, diastolic blood pressure, ultrasensitive C-reactive protein (US-CRP, homocystein, total cholesterol, triglycerides, HDL cholesterol, oxidized LDL, fasted glucose, insulin, HOMA-index, liver transaminases, uric acid, and adipokines like resistin, leptin, and adiponectin.

    The prevalence of morbid obesity is increasing rapidly. Weight reduction is very difficult using diet restriction and physical activity alone. Sibutramine has been shown to be effective and safe as an adjuvant therapy to diet restrictions. To describe our experience using sibutramine in weight reduction treatment of adolescents suffering from morbid obesity. The study group comprised 20 young persons (13 females, mean age 15 years 4 months, range 13-18 years) with morbid obesity (body mass index above the 95th percentile for age and/or > or =30 kg/m2) who were treated with sibutramine 10 mg once a day for 1 year. Mean BMI was 40 +/- 5.6 kg/m2 (range 30.1 - 49.5 kg/m2) at the beginning of treatment. Most patients showed an early weight reduction to mean BMI 39.3 +/- 4.9 and 35.9 +/- 5.7 at 3 and 6 months respectively, but stopped losing weight over the next 6 months. During the follow-up period 17 patients discontinued the treatment. The main reason for dropout was the slow rate of weight reduction after 6 months. Patients suffering from concomitant disorders (severe asthma, hypertension, sleep obstructive apnea) showed improvement after weight reduction. Adverse reactions from the treatment were transient, mild and well tolerated. Sibutramine may help in achieving weight reduction for a short period and in improving concomitant health problems, however its long-term effect is limited.

    Animal data suggest sexually dimorphic programming of obesity in response to altered intrauterine environment, but the longitudinal impact of gestational diabetes mellitus (GDM) on sex-specific risk of offspring obesity in humans is unclear. We conducted a prospective analysis of 15 009 US individuals (7946 female and 7063 male) from the Growing-Up Today Study, who were followed from 1996 (ages 9-14 years) through 2010. Height and weight from validated questionnaires were used to derive body mass index (BMI) at different ages. Obesity during childhood (Obesity Task Force and the World Health Organization criteria. GDM exposure was identified through self-reported questionnaires from mothers. Relative risks were estimated using multivariable log-binomial regression models with generalized estimating equations accounting for clustering within the same family. Male offspring born from pregnancies complicated by GDM had higher BMI compared with non-GDM offspring and had increased risk of obesity; the adjusted relative risk [RR, 95% confidence interval (CI)] was 1.47 (1.11-1.95) for all age groups, 1.59 (1.05-2.41) for late childhood, 1.48 (1.06-2.06) for adolescence and 1.39 (1.00-1.94) for early adulthood. No significant association between obesity and maternal GDM was observed among female participants (RR = 0.97, 95% CI: 0.71-1.33). The association of GDM with offspring obesity from late childhood through early adulthood may differ by sex; a significant association was observed among male but not female offspring.

    Full Text Available Obesity and osteoporosis are two chronic conditions that have been increasing in prevalence. Despite prior data supporting the positive relationship between body weight and bone mineral density (BMD, recent findings show excess body weight to be detrimental to bone mass, strength, and quality. To evaluate whether obesity would further exacerbate the effects of ovariectomy on bone, we examined the tibiae and fourth lumbar (L4 vertebrae from leptin receptor-deficient female (Leprfa/fa Zucker rats and their heterozygous lean controls (Leprfa/+ that were either sham-operated or ovariectomized (Ovx. BMD of L4 vertebra was measured using dual-energy X-ray absorptiometry, and microcomputed tomography was used to assess the microstructural properties of the tibiae. Ovariectomy significantly (P<0.001 decreased the BMD of L4 vertebrae in lean and obese Zucker rats. Lower trabecular number and greater trabecular separation (P<0.001 were also observed in the tibiae of lean- and obese-Ovx rats when compared to sham rats. However, only the obese-Ovx rats had lower trabecular thickness (Tb.Th (P<0.005 than the other groups. These findings demonstrated that ovarian hormone deficiency adversely affected bone mass and quality in lean and obese rats while obesity only affected Tb.Th in Ovx-female Zucker rats.

  10. The impact of hyperandrogenism in female obesity and cardiometabolic diseases associated with polycystic ovary syndrome.

    2013-09-01

    Polycystic ovary syndrome (PCOS) is a common condition characterized by reproductive and hyperandrogenic features and is often associated with obesity and metabolic dysfunction. Overall, women with PCOS have a substantially greater prevalence of metabolic syndrome than women from the general population. Furthermore, PCOS per se (independent of its frequent association with obesity) often confers cardiometabolic risk (including insulin resistance), and its concurrence with obesity often represents a metabolic "double-whammy" from the adverse effects of PCOS and obesity. The introduction of the Rotterdam diagnostic criteria for PCOS in 2003 has broadened the scope of this condition. The Rotterdam diagnostic criteria have also introduced two new phenotypic subgroups (including normoandrogenemic women with PCOS) that have provided novel insights into a potential role for hyperandrogenism in the development of adverse cardiometabolic risk in women with PCOS. Based on evidence from cross-sectional and interventional studies, hyperandrogenism, obesity, and cardiometabolic risk in women appear to be linked through complex and multidirectional pathways. Furthermore, data from obese women without a formal diagnosis of PCOS also suggest that these interrelationships often exist in female obesity per se (in milder forms than occurs in PCOS). Data from female-to-male transsexuals are particularly informative because these show direct effects of hyperandrogenism (induced through exogenous use of androgenic therapies) on fat distribution and cardiometabolic risk in women. A challenge for the future will be to disentangle and improve our understanding of this complex pathogenic web, thereby facilitating novel and targeted therapies for the hyperandrogenic and adverse cardiometabolic manifestations of PCOS.

    The remarkable economic growth in Saudi Arabia has affected the population life style negatively. The increasing problem of obesity has been reported from different regions in the kingdom. The rate of overweight and obesity reached 65.4% in the eastern region among females aged 18-74 years old. Although there is considerable amount of data on prevalence of obesity, yet, data on dietary habits and food consumption pattern are limited. The present study is a cross- sectional descriptive study aimed at exploring the BMI distribution among university female students. Food consumption pattern and health related behaviors were also assessed. 799 students participated in the study; data were collected using self administered questionnaire. Body weight and height were measured to calculate the BMI. Among the study participants, overweight and obesity reached 47.9%. Marriage, presence of obesity among family members, frequency of drinking aerated beverages increased the risk of obesity significantly. Misperception of body image was reported by 17.4% and 54.2% of obese and overweight students respectively. Analysis of dietary habits and life styles indicated the predominance of unhealthy behaviors. The study results mandate the need for a national strategy to adopt healthy dietary habits and life styles.

    Increased sugar-sweetened beverage consumption has been linked to higher rates of obesity. Using functional MRI, we assessed brain perfusion responses to drinking two commonly consumed monosaccharides, glucose and fructose, in obese and lean adolescents. Marked differences were observed. In response to drinking glucose, obese adolescents exhibited decreased brain perfusion in brain regions involved in executive function (prefrontal cortex [PFC]) and increased perfusion in homeostatic appetite regions of the brain (hypothalamus). Conversely, in response to drinking glucose, lean adolescents demonstrated increased PFC brain perfusion and no change in perfusion in the hypothalamus. In addition, obese adolescents demonstrated attenuated suppression of serum acyl-ghrelin and increased circulating insulin level after glucose ingestion; furthermore, the change in acyl-ghrelin and insulin levels after both glucose and fructose ingestion was associated with increased hypothalamic, thalamic, and hippocampal blood flow in obese relative to lean adolescents. Additionally, in all subjects there was greater perfusion in the ventral striatum with fructose relative to glucose ingestion. Finally, reduced connectivity between executive, homeostatic, and hedonic brain regions was observed in obese adolescents. These data demonstrate that obese adolescents have impaired prefrontal executive control responses to drinking glucose and fructose, while their homeostatic and hedonic responses appear to be heightened. Thus, obesity-related brain adaptations to glucose and fructose consumption in obese adolescents may contribute to excessive consumption of glucose and fructose, thereby promoting further weight gain. © 2016 by the American Diabetes Association.

    Lifestyle variables have a key role in the development of abdominal obesity (AO). The objective of this study was to identify lifestyle factors and socioeconomic variables associated with AO in adolescents. This study carried out a school-based survey in the Brazilian city of Maringá in Paraná. The representative sample was of 991 adolescents (54.5% girls) from both public and private high schools selected through multi-stage random sampling. AO was classified according to waist circumference value. The independent variables studied were: gender, age, socioeconomic level, parental and household characteristics, smoking, alcohol use, physical inactivity, sedentary behaviour and nutrition-related habits. Poisson regression was used with robust variance adjustment to analyse the associations. The analysis was stratified by sexes. The prevalence of AO was 32.7% (girls = 36.3%, boys = 28.4%). In girls, excessive intake of fried foods was inversely associated with AO and excessive consumption of soda was positively associated. In boys, the results demonstrated a negative association with excessive consumption of sweets and soda. It is concluded that the prevalence of AO among adolescents was higher in both sexes. AO is associated with different eating habits in females and males and these relationships are mediated by familial contexts.

    Based on year 2000 Centers for Disease Control and Prevention growth charts, approximately 17% of children and adolescents aged 2 to 19 years in the United States have obesity, and almost 32% of children and adolescents are overweight or have obesity. Obesity in children and adolescents is associated with morbidity such as mental health and psychological issues, asthma, obstructive sleep apnea, orthopedic problems, and adverse cardiovascular and metabolic outcomes (eg, high blood pressure, abnormal lipid levels, and insulin resistance). Children and adolescents may also experience teasing and bullying behaviors based on their weight. Obesity in childhood and adolescence may continue into adulthood and lead to adverse cardiovascular outcomes or other obesity-related morbidity, such as type 2 diabetes. Although the overall rate of child and adolescent obesity has stabilized over the last decade after increasing steadily for 3 decades, obesity rates continue to increase in certain populations, such as African American girls and Hispanic boys. These racial/ethnic differences in obesity prevalence are likely a result of both genetic and nongenetic factors (eg, socioeconomic status, intake of sugar-sweetened beverages and fast food, and having a television in the bedroom). To update the 2010 US Preventive Services Task Force (USPSTF) recommendation on screening for obesity in children 6 years and older. The USPSTF reviewed the evidence on screening for obesity in children and adolescents and the benefits and harms of weight management interventions. Comprehensive, intensive behavioral interventions (≥26 contact hours) in children and adolescents 6 years and older who have obesity can result in improvements in weight status for up to 12 months; there is inadequate evidence regarding the effectiveness of less intensive interventions. The harms of behavioral interventions can be bounded as small to none, and the harms of screening are minimal. Therefore, the USPSTF

    Whether adolescent overweight/obesity is linked to socioeconomic status (SES) and fruit and vegetable (F/V) intakes has not been confirmed. We aimed to determine whether there is an association between SES and adolescent overweight/obesity and to test the mediating effect of F/V intakes. This cross-sectional study included the data of 63,111 adolescents extracted from the 2013 Korea Youth Risk Behavior Web-based Survey. Overweight/obesity was defined as a body mass index ≥ 85th percentile, while F/V intakes were categorized as high (recommended levels: ≥1 fruit serving and ≥3 vegetable servings per day) versus low. Among girls, low SES (beta = 0.50, p overweight/obesity; the former association was significantly mediated by F/V intakes (Sobel test: z = 2.00, p = 0.046). Among boys, neither SES nor F/V intakes was significantly associated with overweight/obesity. Adolescent overweight/obesity was significantly linked to low SES and F/V intakes among girls only; low SES indirectly increased the risk of overweight/obesity via low F/V intakes. Therefore, promoting F/V intakes for socially disadvantaged girls should be prioritized as a population-based strategy for preventing adolescent overweight/obesity in South Korea. PMID:27005654

    Full Text Available Background : Adolescence is one of the most critical growth periods in the human's life. Eating disorder is one of the most common nutritional-psychological disorders in this period, which can lead to acute and chronic physical and mental problems. Therefore, regarding the importance of the topic, the present study was designed to determine the prevalence of weight – controlling attitude and eating disorders, and their association with anthropometric indices in female adolescent school students. Materials and Methods: The present study was a cross-sectional descriptive analytical study. 594 high school adolescent girls were selected using multi-stage random sampling method. Nutritional attitude was assessed by use of a nutritional attitude questionnaire. Another specific questionnaire was used to gather demographic and anthropometric information. Data analysis was done using SPSS software, independent t- test and Chi-square (P˂0.05. Results: The information shows that 80% of the studied population are at risk of eating disorders. The number of the obese , over weight and underweight students were significantly more in the group with nutritional attitude disorders. Conclusion: Due to the high prevalence of eating disorders in adolescent girls, and the concomitant obesity and underweight with these disorders, the correction of these attitude could be mentioned as a health priority in this city

  19. Microstructural abnormalities in white and gray matter in obese adolescents with and without type 2 diabetes

    Arie Nouwen

    Full Text Available Aims/hypotheses: In adults, type 2 diabetes and obesity have been associated with structural brain changes, even in the absence of dementia. Some evidence suggested similar changes in adolescents with type 2 diabetes but comparisons with a non-obese control group have been lacking. The aim of the current study was to examine differences in microstructure of gray and white matter between adolescents with type 2 diabetes, obese adolescents and healthy weight adolescents. Methods: Magnetic resonance imaging data were collected from 15 adolescents with type 2 diabetes, 21 obese adolescents and 22 healthy weight controls. Volumetric differences in the gray matter between the three groups were examined using voxel based morphology, while tract based spatial statistics was used to examine differences in the microstructure of the white matter. Results: Adolescents with type 2 diabetes and obese adolescents had reduced gray matter volume in the right hippocampus, left putamen and caudate, bilateral amygdala and left thalamus compared to healthy weight controls. Type 2 diabetes was also associated with significant regional changes in fractional anisotropy within the corpus callosum, fornix, left inferior fronto-occipital fasciculus, left uncinate, left internal and external capsule. Fractional anisotropy reductions within these tracts were explained by increased radial diffusivity, which may suggest demyelination of white matter tracts. Mean diffusivity and axial diffusivity did not differ between the groups. Conclusion/interpretation: Our data shows that adolescent obesity alone results in reduced gray matter volume and that adolescent type 2 diabetes is associated with both white and gray matter abnormalities.

    The objective of the present study was to test if outcome expectancy mediated the relationship between fitness and self-efficacy, perceived stress, and depressive symptoms.Adolescents with obesity ( n = 228) completed measures of perceived stress and depressive symptoms at baseline, self-efficacy and outcome expectancy at baseline and 3 months, and fitness at baseline and 6 months. Structural equation modeling was used to analyze the data. Results showed that self-efficacy was positively associated with fitness via outcome expectancies. For females, fewer depressive symptoms were linked to fitness via self-efficacy and outcome expectancies. Exercise interventions that enhance exercise self-efficacy, outcome expectancy, and reduce depressive symptoms may increase fitness.

    Obesity in children and adolescents has reached alarming levels--20%-25% of children and adolescents are overweight or obese, and 4.9% of boys and 5.4% of girls are obese. Rates of obesity have increased significantly in Australia from 1985 to 1995, with the prevalence of overweight doubling and obesity trebling. Body mass index (related to reference standards for age and sex) is recommended as a practical measure of overweight and obesity in children, and is used in monitoring individual progress in clinical practice. Obesity in childhood and adolescence may be associated with a range of medical and psychological complications, and can predispose individuals to serious health problems in adult life, including type 2 diabetes, hypertension, dyslipidaemia and non-alcoholic steatohepatitis. Obesity interventions for which there is some evidence include family support, a developmentally appropriate approach, long-term behaviour modification, dietary change, and increased physical activity and decreased sedentary behaviour. Prevention of obesity in children and adolescents requires a range of strategies involving changes in both the microenvironment (eg, housing, neighbourhoods, recreational opportunities) and the macroenvironment (eg, food marketing, transport systems, urban planning).

    mother's education level. RESULTS: Most (64.7% of the teenagers were female. The mean age was 12.4 years (SD=1.80, aged 8 to 17 years. The prevalence of obesity and overweight was higher in boys. No statistical difference was found between nutritional status and gender. After the adjustments, the data show that children of obese mothers were 4 times more likely to be at risk of obesity than children of normal weight mothers. CONCLUSION: Maternal obesity is a great risk factor for adolescent obesity.

    Full Text Available Objective: To verify the prevalence of metabolic syndrome and insulin resistance in obese adolescents and its relationship with different body composition indicators. Methods: A cross-sectional study comprising 79 adolescents aged ten to 18 years old. The assessed body composition indicators were: body mass index (BMI, body fat percentage, abdominal circumference, and subcutaneous fat. The metabolic syndrome was diagnosed according to the criteria proposed by Cook et al. The insulin resistance was determined by the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR index for values above 3.16. The analysis of ROC curves was used to assess the BMI and the abdominal circumference, aiming to identify the subjects with metabolic syndrome and insulin resistance. The cutoff point corresponded to the percentage above the reference value used to diagnose obesity. Results: The metabolic syndrome was diagnosed in 45.5% of the patients and insulin resistance, in 29.1%. Insulin resistance showed association with HDL-cholesterol (p=0.032 and with metabolic syndrome (p=0.006. All body composition indicators were correlated with insulin resistance (p<0.01. In relation to the cutoff point evaluation, the values of 23.5 and 36.3% above the BMI reference point allowed the identification of insulin resistance and metabolic syndrome. The best cutoff point for abdominal circumference to identify insulin resistance was 40%. Conclusions: All body composition indicators, HDL-cholesterol and metabolic syndrome showed correlation with insulin resistance. The BMI was the most effective anthropometric indicator to identify insulin resistance.

    Physiological and behavioral aspects of masticatory function may have an impact on nutritional status, which has been little studied. The aim was to perform a comprehensive evaluation of objective, subjective and behavioral aspects of masticatory function in 231 adolescents, aged 14-17 years and compare these parameters between normal-weight (n = 115) and adolescents with overweight/obesity (n = 116). Objective aspects were examined by the Oro-facial Myofunctional Evaluation-expanded protocol (OMES-e), determining the masticatory type, chewing time/frequency, abnormal movements, and other; masticatory performance (color changeable chewing gum) and bite force were also explored. The subjective and behavioral evaluations were assessed using the Quality of Mastication Function Questionnaire, which explores the masticatory behavior and frequency/intensity of difficulty in chewing different types of foods. Results were submitted to normality tests, Chi-square, unpaired t-test and Mann-Whitney. A multiple linear regression model was used to evaluate which of the variables under study contributed to the variation in Percent Body Fat (α = 0.05). The results showed that OMES-e total score differed significantly between groups, that is, individuals with overweight showed more changes in oro-facial myofunctional aspects than normal-weight ones. Unilateral mastication was more frequent among females with overweight/obesity. They also showed greater difficulty on Habits and Fruit domains, reporting the need of adding sauce to the meal to facilitate swallowing and peeling and cutting fruit (apples) in small pieces in order to better chew them. OMES-e total score also showed a significant relationship with Percent Body Fat. Masticatory performance evaluated by chewing gum and bite force did not differ between groups. This study showed that adolescents with excess weight presented changes in masticatory behavior and greater difficulty in performing the masticatory function

    Pharmacological approaches to reduce obesity have not resulted in dramatic reductions in the risk of coronary heart disease (CHD). Exercise, in contrast, reduces CHD risk even in the setting of obesity. Cholesteryl Ester Transfer Protein (CETP) is a lipid transfer protein that shuttles lipids between serum lipoproteins and tissues. There are sexual-dimorphisms in the effects of CETP in humans. Mice naturally lack CETP, but we previously reported that transgenic expression of CETP increases muscle glycolysis in fasting and protects against insulin resistance with high-fat diet (HFD) feeding in female but not male mice. Since glycolysis provides an important energy source for working muscle, we aimed to define if CETP expression protects against the decline in exercise capacity associated with obesity. We measured exercise capacity in female mice that were fed a chow diet and then switched to a HFD. There was no difference in exercise capacity between lean, chow-fed CETP female mice and their non-transgenic littermates. Female CETP transgenic mice were relatively protected against the decline in exercise capacity caused by obesity compared to WT. Despite gaining similar fat mass after 6 weeks of HFD-feeding, female CETP mice showed a nearly two-fold increase in run distance compared to WT. After an additional 6 weeks of HFD-feeding, mice were subjected to a final exercise bout and muscle mitochondria were isolated. We found that improved exercise capacity in CETP mice corresponded with increased muscle mitochondrial oxidative capacity, and increased expression of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α). These results suggest that CETP can protect against the obesity-induced impairment in exercise capacity and may be a target to improve exercise capacity in the context of obesity.

We found that improved exercise capacity in CETP mice corresponded with increased muscle mitochondrial oxidative capacity, and increased expression of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α. These results suggest that CETP can protect against the obesity-induced impairment in exercise capacity and may be a target to improve exercise capacity in the context of obesity.

    Full Text Available Resveratrol has antioxidant, anti-inflammatory, lipolytic, and antifibrotic properties, which may be useful in supplementation of obese patients and with liver problems. This study evaluated the effects of 6-week resveratrol supplementation on the lipid profile and liver function of female Wistar rats fed a high-fat diet to induce obesity. Sixty-four Wistar rats were divided into 4 groups (n = 16: the control group (C; the control obese group (CO; the resveratrol group (R; and the resveratrol obese group (RO. At the end of the experiment, the animals were anesthetized for blood collection and subsequent euthanasia for collection of liver biopsy. The parameters for body weight, liver weight, retroperitoneal fat weight, serum lipid and liver profiles and histopathological analysis were evaluated. The 6-week resveratrol administration did not induce weight loss nor did it reduce the lipid profile; however, it decreased the liver enzymes aspartate aminotransferase (AST and alkaline phosphatase (ALP and reduced the incidence of steatosis (75.0% in group RO compared with group CO (81.2%. Thus, we concluded that resveratrol supplementation for the short period of six weeks had a beneficial effect on liver function by reducing hepatic steatosis and the liver enzymes AST and ALP in obese female rats. Keywords: liver function; obesity; rats; resveratrol.

    The global obesity epidemic is having a profound impact on the health of populations. From a reproductive standpoint, obesity has been associated with infertility and hypogonadism. We present the case of a 29-year-old male-to-female transsexual with super obesity (body mass index >50) who was found to have profound hypogonadism with total and free testosterone levels in the normal female reference range. There is virtually no literature on the hormonal sequelae of obesity in transsexual people. The patient was prescribed an aromatase inhibitor, letrozole 2.5 mg twice daily for 2 weeks, to determine the role of oestrogen in the hypogonadism. The aromatase inhibitor reduced the serum oestradiol concentration from 125 to 6.9 pm. There were dramatic corresponding rises in total testosterone (2.8 to 10.7 nm), luteinising hormone (4.1 to 20.5 mIU ml(-1) ) and follicle stimulating hormone (1.8 to 15.3 mIU ml(-1) ). This diagnostic test demonstrated the important role of oestrogen in mediating the hypogonadism. After the testing, the patient was started on oestrogen therapy after a careful discussion of the benefits versus risks of oestrogen therapy. We anticipate that similar cases of hypogonadism in male-to-female transsexuals will likely become more common in an era of increased obesity rates. © 2012 Blackwell Verlag GmbH.

  9. Low Serum Paraoxonase-1 Lactonase and Arylesterase Activities in Obese Children and Adolescents

    2015-12-01

    Full Text Available Serum paraoxonase-1 (PON1 binds mainly to high density lipoproteins (HDLs and protects low density lipoproteins (LDLs against oxidation. While paraoxonase and arylesterase activities are traditionally assayed, lactonase activity, accounting for protection against LDL oxidation, was less investigated in obese children and adolescents. Therefore, we aimed to measure lactonase, paraoxonase and arylesterase activities, oxidized LDL (ox-LDL and malondialdehyde (MDA levels in obese children and adolescents.

    Background Severe obesity has increased yet childhood antecedents of adult severe obesity are not well understood. Objective Estimate adult-onset severe obesity risk in individuals with history of childhood physical and/or sexual abuse compared to those who did not report abuse. Methods Longitudinal analysis of participants from the U.S. National Longitudinal Study of Adolescent Health (N=10,774) Wave II (1996; aged 12–22 years) followed through Wave IV (2008–09; aged 24–34 years). New cases of adult-onset severe obesity (BMI≥40 kg/m2 using measured height and weight) in individuals followed over 13 years who were not severely obese during adolescence (BMI childhood was associated with an increased risk of incident severe obesity in adulthood in non-minority females (Hazard Ratio=2.5; 1.3, 4.8) and males (Hazard Ratio=3.6; 1.5, 8.5) compared to individuals with no history of abuse. Conclusion In addition to other social and emotional risks, exposure to sexual and physical abuse during childhood may increase risk of severe obesity later in life. Consideration of the confluence of childhood abuse might be considered as part of preventive and therapeutic approaches to address severe obesity. PMID:24115589

    Purpose: This study evaluated the arsenic methylation profile of adolescents and explored the influence of body mass index (BMI) on the arsenic methylation profile of adolescents in an area of Taiwan with no-obvious arsenic exposure. Methods: This study evaluated 202 normal weight students and 101 obese students from eight elementary schools, recruited from September 2009 to December 2009. Concentrations of urinary arsenic species, including inorganic arsenic, monomethylarsonic acid (MMA 5+ ) and dimethylarsinic acid (DMA 5+ ) were determined by a high-performance liquid chromatography-linked hydride generator and atomic absorption spectrometry. Results: Urinary total arsenic was significantly decreased with increasing BMI, indicating that obese children may retain higher levels of arsenic in the body, as compared to normal weight children. Participants with obesity accompanied by high insulin levels had higher inorganic arsenic, significantly higher MMA percentage and significantly lower DMA percentage than those with obesity and low insulin levels. It seems children with obesity and high insulin levels had lower arsenic methylation capacity than those with obesity and low insulin. Conclusions: This is the first study to demonstrate that total urinary arsenic is negatively associated with the BMI in adolescents in Taiwan, adjusted for age and sex. Obese adolescents with high insulin levels had significantly higher MMA% and significantly lower DMA% than obese adolescents with low insulin. - Highlights: ► This is the first to find that urinary total arsenic is related inversely to the BMI. ► Arsenic methylation capability may be associated with obesity and insulin. ► Obese adolescents with high insulin had low arsenic methylation capacity.

    Initial antidepressant treatment can paradoxically worsen symptoms in depressed adolescents by undetermined mechanisms. Interestingly, antidepressants modulate GABAA receptors, which mediate paradoxical effects of other therapeutic drugs, particularly in females. Although the neuroanatomic site of action for this paradox is unknown, elevated GABAA receptor signaling in the nucleus accumbens can disrupt motivation. We assessed fluoxetine's effects on motivated behaviors in pubescent female hamsters - anhedonia in the reward investigational preference (RIP) test as well as anxiety in the anxiety-related feeding/exploration conflict (AFEC) test. We also assessed accumbal signaling by RT-PCR and electrophysiology. Fluoxetine initially worsened motivated behaviors at puberty, relative to adulthood. It also failed to improve these behaviors as pubescent hamsters transitioned into adulthood. Low accumbal mRNA levels of multiple GABAA receptor subunits and GABA-synthesizing enzyme, GAD67, assessed by RT-PCR, suggested low GABAergic tone at puberty. Nonetheless, rapid fluoxetine-induced reductions of α5GABAA receptor and BDNF mRNA levels at puberty were consistent with age-related differences in GABAergic responses to fluoxetine and disruption of the motivational state. Whole-cell patch clamping of accumbal slices also suggested low GABAergic tone by the low amplitude of miniature inhibitory postsynaptic currents (mIPSCs) at puberty. It also confirmed age-related differences in GABAergic responses to fluoxetine. Specifically, fluoxetine potentiated mIPSC amplitude and frequency at puberty, but attenuated the amplitude during adulthood. These results implicate GABAergic tone and GABAA receptor plasticity in adverse motivational responses and resistance to fluoxetine during adolescence. Copyright © 2016 Elsevier Inc.

    To assess the impact of acanthosis nigricans (AN) on depression symptoms, related quality of life and self-esteem scores in obese adolescent girls. Fifty-nine obese adolescent girls (mean age: 13.19±1.3 years, age range: 12-17 years, mean body mass index: 29.89±3.30) were enrolled in this study. The obese adolescent girls were divided into two groups based on presence or absence of AN. Non-obese healthy adolescents constituted the control group (30 girls, mean age: 13.5±1.4 years). All subjects were evaluated using the Children's Depression Inventory (CDI), the State-Trait Anxiety Inventory for Children (STAI-C), and the modified Rosenberg Self-Esteem Scale (SES). Higher scores indicated more severe depression and anxiety, as well as low self-esteem status. The AN and non-AN obese groups showed significantly higher CDI, STAI-C and SES scores than the control group, and the two obese groups demonstrated no significant differences for these scores. The AN obese group with higher total testosterone levels (>50 ng/dL) had higher scores for SES (2.55±1.8 vs. 1.42±1.2; p=0.03) than the AN obese group with low total testosterone levels. SES scores significantly correlated with total testosterone levels (r=0.362; p=0.03) and fasting insulin (r=0.462; p=0.03) in the AN obese group. Higher SES scores (low self-esteem status) were determined in obese adolescents with acanthosis and were related to hyperandrogenism. This study also showed that a high testosterone level may be one of the important indicators of low self-esteem status in obese girls with AN.

    Obesity is a chronic disease which causes medical and psychiatric complications. Family climate is also a critical factor in the presence and treatment of obesity and comorbid psychiatric disorders. In our study, perceived expressed emotion (EE), psychopathology, self-esteem and emotional and behavioural problems among obese adolescents will be investigated by comparison with their non-obese peers. This study was carried out with 49 obese adolescents and 47 non-obese adolescents as a control group. All participants were requested to fill out the Socio-demographic Data Form, Shortened Level of Expressed Emotion Scale, Rosenberg Self-Esteem Scale, Strength and Difficulties Questionnaire-Adolescent Form. In our study, obese adolescents showed a significant difference in perceived EE (pself-esteem (pself esteem. A higher rate of perceived EE, psychopathology and low self-esteem among obese adolescents showed that obesity prevention and treatment are also crucial for mental health in adolescents. With the help of our study results, we aimed to emphasize the role of the family in obese adolescent's mental health and their treatment. By the help of our results we try to identifying risk factors in childhood that promote obesity in order to help develop targeted intervention and prevention programs.

    The global epidemic of obesity and physical inactivity may have detrimental implications for young people's cognitive function and academic achievement. This prospective study investigated whether childhood motor function predicts later academic achievement via physical activity, fitness, and obesity. The study sample included 8,061 children from the Northern Finland Birth Cohort 1986, which contains data about parent-reported motor function at age 8 y and self-reported physical activity, predicted cardiorespiratory fitness (cycle ergometer test), obesity (body weight and height), and academic achievement (grades) at age 16 y. Structural equation models with unstandardized (B) and standardized (β) coefficients were used to test whether, and to what extent, physical activity, cardiorespiratory fitness, and obesity at age 16 mediated the association between childhood motor function and adolescents' academic achievement. Physical activity was associated with a higher grade-point average, and obesity was associated with a lower grade-point average in adolescence. Furthermore, compromised motor function in childhood had a negative indirect effect on adolescents' academic achievement via physical inactivity (B = -0.023, 95% confidence interval = -0.031, -0.015) and obesity (B = -0.025, 95% confidence interval = -0.039, -0.011), but not via cardiorespiratory fitness. These results suggest that physical activity and obesity may mediate the association between childhood motor function and adolescents' academic achievement. Compromised motor function in childhood may represent an important factor driving the effects of obesity and physical inactivity on academic underachievement.

    The global prevalence of obesity has reached alarming proportions. In Cuba, the rise in numbers of children who are overweight or obese, especially preschoolers and adolescents, is similar to that observed in developed countries. Beyond the physical risk factors, there is evidence that obesity has negative psychological, social, academic and economic effects. Describe the psychological, behavioral and familial factors present in a group of obese children and adolescents in Cuba. This is a qualitative cross-sectional study of 202 obese children and adolescents aged 3-18 years, with an average age of 9.9 years, seen at the Medical-Surgical Research Center (Havana) psychology service from January 2009 through December 2012. Techniques included interviews of patients and parents, projective drawings and the Rotter Incomplete Sentence Blank. Unhealthy eating habits were reported in 96% of obese children and adolescents, and sedentary lifestyles in 88.1%. Emotional state was affected in 80.2%, and in 72.3% there were family attitudes with potential to produce psychological disturbances in children. Psychological, behavioral, and familial factors known to foster development and perpetuation of obesity were observed in the majority of cases. This is a first diagnostic stage that will aid in design and implementation of a psychological intervention program for obese and overweight children and their families.

    Full Text Available PurposePrevious reports show an association between high serum ferritin levels and metabolic syndrome (MS in adults. In adolescents, little information is available with obesity and serum ferritin levels.MethodsThis is a cross-sectional study. Data were obtained from the 5th Korean National Health and Nutrition Examination Survey (K-NHANES conducted during 2010 by the Korean Ministry of Health and Welfare. A total of 849 subjects aged 10-18 years participated in the 2010 survey. A body mass index (BMI ≥95th percentile for age and sex or a BMI ≥25 was used to diagnose as obesity.ResultsThe weighted prevalence of obesity was 13.4% (62/462 in male and 8.5% (33/387 in female. We observed significantly higher serum ferritin in male than in female (mean±standard error [SE], 50.5±2.3 µU/L vs. 30.6±1.3 µU/L; P<0.0001. In male, serum ferritin is positively correlated with age (P<0.0001. White blood cell (WBC count, serum fasting blood sugar, triglyceride (TG, total cholesterol, low-density lipoprotein, insulin, homeostasis model assessment-insulin resistance (HOMA-IR, systolic and diastolic blood pressure, and ferritin levels were higher and high-density lipoprotein (HDL were lower in the obesity than in the normal group. In female adolescents, WBC count, TG, insulin, and HOMA-IR were higher and HDL were lower in the obesity than in the normal group. In male, serum ferritin levels showed positive association with obesity (β=21.196, P=0.016.ConclusionSerum ferritin levels appear to be associated with obesity in Korean male adolescents.

Along with a brief demographic questionnaire, global self-esteem was measured by Rosenberg's Self-Esteem Scale, decision making was measured by the Flinders Adolescent Decision Making Questionnaire, and sexual activity and contraception use was measured by a nonnormed Sexual History and Contraceptive Use Questionnaire developed for this study. Descriptive statistics, logistic regression, and correlations were used to analyze associations and correlations between age, global self-esteem, decision self-esteem, decision coping (vigilant and maladaptive), and contraceptive use for sexually active female adolescents. No significant associations or correlations were found between age, global self-esteem, decision self-esteem, decision coping (vigilance), and the decision to use contraception in sexually active adolescent females. There was, however, significant negative correlation (p skills and stimulating thinking around not only sexual issues but also on relationship and communication in adolescent issues may facilitate more competent decision making. Understanding the relationship between female adolescent self-esteem, decision making, and contraceptive behavior has contributed to the knowledge base about female contraceptive behavior. Gaining further insight into these relationships will help healthcare professionals provide counseling and health care to female adolescents.

    Leptin (LEP) G-2548A (rs7799039), leptin receptor (LEPR) Q223R (rs1137101) and tumor necrosis factor (TNF)-α G-308A (rs1800629) gene variants have been reported to be associated with obesity, although results for subjects from different countries have been controversial. The aim of this study was to determine the prevalence of overweight and obesity in Malaysian adolescents and the association of these polymorphisms with overweight and obese or over-fat adolescents. A total of 613 adolescents (241 Malay, 219 Chinese, 153 Indian) were enrolled. Anthropometric measurements of body mass index (BMI) and body fat percentage were used to classify subjects as controls (non-overweight/obese or normal fat) or as cases (overweight/obese or over-fat). Genomic DNA was extracted from oral buccal mucosa cells for genotyping using polymerase chain reaction-restriction fragment length polymorphism and data obtained were statistically analyzed. A total of 23.3% of subjects were overweight/obese whereas 11.4% were over-fat; there were significantly more overweight/obese and over-fat Indian and Malay adolescents compared to Chinese (P obesity (P = 0.025; odds ratio, 3.64; 95% confidence interval: 1.15-11.54). Despite the lack of association observed for LEPR Q223R and TNF-α G-308A, Indian and Chinese subjects with AA risk genotype for LEPR Q223R/LEP G-2548A and TNF-α G-308A/LEP G-2548A, respectively, had increased mean BMI (P = 0.049, P = 0.016). Genotype distribution and association of these polymorphisms with overweight/obesity vary between ethnic groups and genders. Nevertheless, the LEP G-2548A risk allele may be associated with overweight/obese Indian male adolescents in Malaysia. © 2014 Japan Pediatric Society.

    According to recent research studies, the built and socioeconomic contexts of neighborhoods are associated with African American adolescents' participation in physical activity and obesity status. However, few research efforts have been devoted to understand how African American adolescents' perceptions of their neighborhood environments may affect physical activity behaviors and obesity status. The objective of the current study was to use a perceived neighborhood disorder conceptual framework to examine whether physical activity mediated the relationship between perceived neighborhood disorder and obesity status among African American adolescents. The data were obtained from a cross-sectional study that examined social and cultural barriers and facilitators of physical activity among African American adolescents. The study included a sample of 101 African American adolescents age 12 to 16 years and their parents who were recruited from the Birmingham, Alabama metropolitan area. The primary outcome measure was obesity status which was classified using the International Obesity Task Force cut off points. Moderate-to-vigorous physical activity was assessed via accelerometry. Perceived neighborhood disorder was assessed using the Perceived Neighborhood Disorder Scale. Mediation models were used to examine whether the relationship between neighborhood disorder and obesity status was mediated by physical activity. Perceived neighborhood disorder was significantly and positively related to obesity status and moderate-to-vigorous physical activity was inversely associated with obesity status. However, there was no evidence to support a significant mediating effect of moderate-to-vigorous physical activity on the relationship between neighborhood disorder and obesity status. Future studies should longitudinally assess perceived neighborhood disorder characteristics and childhood adiposity to examine the timing, extent, and the mechanisms by which perceived neighborhood

    This review examines the impact of mobile app technology on obesity-related anthropometric, psychosocial, and behavioral outcomes in children and adolescents. Nine research articles retrieved from a systematic review of the literature met criteria. Evidence is limited and mixed, but argues for an impact of mobile app use on motivation and goal-setting behavior, and supports further study of the impact on childhood obesity-related outcomes such as attitudes, perceptions, physical activity, and dietary habits. Nurses can use this evidence to discuss potential benefits of health promotion mobile apps with parents, children, and adolescents to combat childhood obesity. © 2015, Wiley Periodicals, Inc.

    To compare prevalence of overweight/obesity among adolescent school children of government and private schools. A school-based cross-sectional study was conducted in 1800 children aged 10-16 years. Body mass index (BMI), Waist circumference (WC), Hip circumference (HC), and Neck circumference (NC) were measured using standard guidelines. The prevalence of overweight obesity was 27.8% (private schools 45.2%, government schools 10.5%). BMI, WC, NC, and Waist-hip ratio were significantly higher among private school students. A differential strategic plan may be needed to prevent and control obesity among adolescent school children.

    Full Text Available AIM: To evaluate body composition changes after use of three different types of obesity management protocols: dietary measures and physical activity; acupuncture or laser acupuncture with healthy diet; aiming at achieving stable weight loss among obese Egyptian females. METHODS:  A randomized longitudinal prospective study included 76 obese adult females; aged 26 up to 55 years. Anthropometric, body composition, ultrasonographic and biochemical assessments were done. RESULTS: The three types of obesity management protocols showed significant improvement in body composition (decrease in fat% and increases in FFM and TBW and visceral fat by US. However, nutritional intervention showed highly significant improvement in the skin fold thickness at triceps and biceps sites and peripheral adiposity index.  Acupuncture intervention showed highly significant improvement in fasting blood glucose (decreased and lipid profile (decreased triglycerides, total cholesterol and LDL, and increased HDL. Laser intervention showed highly significant improvement in all the skin fold thickness and some parameters of lipid profile (decreased total cholesterol and LDL. CONCLUSIONS: The three obesity management protocols have significant effect on body composition, but acupuncture has the best effect in improving the lipid profile and fasting blood sugar. In addition, Laser intervention was recommended to improve skin fold thickness and subcutaneous fat.

    The aim of this study was to find out the association of media and obesity status with body weight concern among female university students in Kuwait. 228 female students, aged 19-25 years, were selected at convenience from the Women's College in Kuwait. A previously validated questionnaire was used to collect information on the role of media in body concern and how parents, peers and the girls themselves perceived girls' body shapes. Weight and height were gathered by self-reporting. Use of internet and reading women's magazines had a significant impact on dieting by the girls to lose weight (Pobese girls than non-obese girls. Only watching television had a significant impact on girls' body shape concern (Pobese and 81% of obese girls were dissatisfied with their current weight. There were significant differences between obese and non-obese girls regarding the girls' views and the views of their peers and parents about the body weight of the girls (P<0.000 for all). The pressure from peers and parents, in addition to the mass media, may lead to disturbed attitudes towards eating among Kuwaiti girls. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Morbid obesity is a highly prevalent condition that is associated with a high risk of various diseases and high health care costs. Understanding determinants of eating behaviours that are characteristic of many morbidly obese persons is important for the development of new interventions aimed at changing eating behaviour after bariatric surgery. Dispositional mindfulness seems promising as one such potential determinant. Therefore, the association between mindfulness and eating behaviour was examined in females and males with morbid obesity. Outpatients with morbid obesity who were candidates for bariatric surgery (N = 335; 78.8% female) completed the Dutch Eating Behaviour Questionnaire (DEBQ), the Freiburg Mindfulness Inventory (FMI) and the Hospital Anxiety and Depression Scale (HADS), in addition to the collection of relevant demographic and medical data. Three separate multiple regression analyses with three eating behaviour styles (restrained, emotional, external) as dependent variables showed that mindfulness was positively associated with restrained eating behaviour (Beta = .28, p ≤ .001), and negatively associated with emotional (Beta = -.22, p ≤ .001) and external (Beta = -.32, p ≤ .001) eating behaviours, independent of sex, age, educational level, Body Mass Index and affective symptoms. Dispositional mindfulness was associated with more restrained, and less emotional and external eating behaviour in morbidly obese outpatients, above and beyond affective symptoms. Future studies, establishing the causal direction of the associations, are needed. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available The aim of this study was to evaluate the association between the family history (FH of type 2 diabetes and metabolic syndrome (MetS in a group of non-diabetic obese female subjects. A cross-sectional study was conducted in 239 female patients with obesity, regularly attending the Internal Medicine Division’s outpatient clinic (Hospital de Clínicas de Porto Alegre, Brazil. The inclusion criteria were patients with body mass index ?30 kg/m2 and absence of type 2 diabetes. The FH was considered positive if a first degree relative had a diagnosis of diabetes. Seventy-four of 239 patients evaluated (30% had a positive FH for type 2 diabetes. Patients with positive FH had higher waist/hip ratio and MetS more often than patients with negative FH. FH of type 2 diabetes was associated with MetS in this sample of non-diabetic obese female patients. Waist/hip ratio and fasting plasma glucose, markers of insulin resistance, were also associated with FH of type 2 diabetes. The simple question: “Do you have a FH of type 2 diabetes?” may help to identify the obese patients that should be better evaluated and intensively treated with the objective of preventing type 2 diabetes.

    Full Text Available The GLUT4 transporter plays a key role in insulin-induced glucose uptake, which is impaired in insulin resistance. The objective of the present study was to investigate the tissue content and the subcellular distribution of GLUT4 protein in 4- to 12-year-old control, obese and insulin-treated diabetic mongrel female dogs (4 animals per group. The parametrial white adipose tissue was sampled and processed to obtain both plasma membrane and microsome subcellular fractions for GLUT4 analysis by Western blotting. There was no significant difference in glycemia and insulinemia between control and obese animals. Diabetic dogs showed hyperglycemia (369.9 ± 89.9 mg/dl. Compared to control, the plasma membrane GLUT4, reported per g tissue, was reduced by 55% (P < 0.01 in obese dogs, and increased by 30% (P < 0.05 in diabetic dogs, and the microsomal GLUT4 was increased by ~45% (P < 0.001 in both obese and diabetic animals. Considering the sum of GLUT4 measured in plasma membrane and microsome as total cellular GLUT4, percent GLUT4 present in plasma membrane was reduced by ~65% (P < 0.001 in obese compared to control and diabetic animals. Since insulin stimulates GLUT4 translocation to the plasma membrane, percent GLUT4 in plasma membrane was divided by the insulinemia at the time of tissue removal and was found to be reduced by 75% (P < 0.01 in obese compared to control dogs. We conclude that the insulin-stimulated translocation of GLUT4 to the cell surface is reduced in obese female dogs. This probably contributes to insulin resistance, which plays an important role in glucose homeostasis in dogs.

This study was carried out to compare neostigmine induced reversal of vecuronium in normal weight, overweight and obese female patients, objectively using neuromuscular (NM monitoring. Methods: Twenty female patients each belonging to normal weight, overweight and obese, based on body mass index, requiring general anaesthesia were recruited for this prospective cross sectional study. NMB was induced with vecuronium (0.1 mg/kg dose based on patient′s real body weight (RBW and monitored using acceleromyographic train of four (TOF.

Statistical analysis was done using analysis of variance test. Results: Recovery of TOF ratio to 0.5 was comparable in all three groups. Recovery of TOF ratio to 0.7 was delayed in obese (9.82 ± 3.21 min compared with normal weight group (7.50 ± 2.52 min. Recovery of TOF to 0.9 was significantly delayed in both overweight (12.18 ± 4.29 min and obese patients (13.78 ± 4.30 min. DUR 25% was significantly longer in overweight (mean, standard deviation [range]; 30.10 [19-40 min] and obese (28.8 [12-45 min] compared with normal weight patients (22.75 [16-30 min]. Conclusion: In overweight and obese patients, when vecuronium induction dose is based on RBW, neostigmine induced recovery of NMB is delayed in late phases (TOF 0.7-0.9, which may result in vulnerability for associated complications of incomplete recovery. Ensuring safe recovery thus requires objective NM monitoring.

    The objective of this study is to examine the association between physical and sexual violence exposure and somatic symptoms among female adolescents. We studied a nationally representative sample of 8,531 females, aged 11-21 years, who participated in the 1994-1995 Wave I of the National Longitudinal Study of Adolescent Health (Add Health). Female adolescents were asked how often they had experienced 16 specific somatic symptoms during the past 12 months. Two summary categorical measures were constructed based on tertiles of the distributions for the entire female sample: (a) total number of different types of symptoms experienced, and (b) number of frequent (once a week or more often) different symptoms experienced. Groups were mutually exclusive. We examined associations between adolescents' violence exposure and somatic symptoms using multinomial logistic regression analyses. About 5 % of adolescent females reported both sexual and non-sexual violence, 3 % reported sexual violence only, 36 % reported non-sexual violence only, and 57 % reported no violence. Adolescents who experienced both sexual and non-sexual violence were the most likely to report many different symptoms and to experience very frequent or chronic symptoms. Likelihood of high symptomatology was next highest among adolescents who experienced sexual violence only, followed by females who experienced non-sexual violence only. Findings support an exposure-response association between violence exposure and somatic symptoms, suggesting that symptoms can be markers of victimization. Treating symptoms alone, without addressing the potential violence experienced, may not adequately improve adolescents' somatic complaints and well-being.

    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.

    To assess the relationship between the degree of waist circumference (WC) and nonalcoholic fatty liver disease (NAFLD) in obese adolescents of both genders, analyzed according to quartiles of WC. Cross-sectional study that involved 247 obese adolescents aged 12-19 years. Mean values of the nutritional parameters and serum analyses were compared with the groups using the independent t-test. Pearson correlation coefficient was used to determine the relationship of the parameters studied. Chi-square test for trend was used to determine the relationship between the prevalence of the NAFLD and WC quartile by gender. NAFLD were presented in 60% of the study participants. Obese adolescents in the 3rd and 4th quartiles of WC presented higher prevalence of NAFLD when compared with that in the 1st quartile in both genders. The NAFLD patients had significantly higher values for body weight, BMI (body mass index), BAZ-score (BMI-for-age z-scores), total fat (% and kg), WC, visceral fat, insulin, insulin resistance index (HOMA-IR), aspartate aminotransferase and alanine aminotransferase, when compared with non-NAFLD obese adolescents. The results presented here suggest that an increase in WC can reliably predict the risk of NAFLD in obese adolescents. This is a low cost and easy-to-use tool that can help in screening in adolescents. Copyright © 2015 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda. All rights reserved.

    Child abuse is associated with obesity in adulthood through multiple mechanisms. However, little is known about the relationship between abuse and obesity during adolescence. The aim of this study was to investigate, using a birth cohort, whether there is an association between child abuse and overweight or obesity in adolescence. This study utilizes data from the Avon Longitudinal Study of Parents and Children, a prospective cohort study based in South West England. Using data from the 4205 children with complete data at 13 and 16 years, we analyzed body mass index (BMI) and anonymous parental report of abuse. Abuse was categorized as emotional, physical, or sexual. A sub-sample of 3429 had BMI recorded at 18 years, enabling a longitudinal analysis of BMI trajectories. Using linear and logistic regression analysis, adjusting for sex and family adversity, no association was found between child abuse and BMI, BMI Z-scores, overweight, or obesity, at 13 or 16 years, with all confidence intervals straddling the null. There was weak evidence of a negative association between physical and emotional abuse and BMI trajectories between 13 and 18 years. No relationship was found between child abuse and adolescent obesity in this cohort. This challenges the assumption that adolescent obesity is linked to previous child abuse, as demonstrated for obesity in adult life. A further longitudinal study utilizing both parental and child reports with data record linkage, to improve reporting of abuse, and including neglect as an abuse category, would be desirable.

    Full Text Available Objective: To evaluate the presence of family breakdown factors among eutrophic and overweight/obese adolescents. Methods: Cross-sectional study of 242 students aged between 14 and 19 years old, from a public school. Each student was weighed, measured and answered a questionnaire with closed questions addressing the presence of family breakdown factors. The adolescents were divided in two groups: euthophic and overweight/obese. The answers of both groups were compared by Fisher's exact and Mann-Whitney tests. Results: There was no statistically significant difference in the prevalence of the studied factors between the two groups. Comparing the number of positive answers (presence of family breakdown factors and negative ones (absence of family breakdown factors, no difference was observed between the groups. Conclusions: The inclusion of a control group showed that factors of family breakdown, usually identified as associated with obesity in adolescents, may also be present in eutrophic adolescents.

    In the U.S., an astonishing 12.5 million children and adolescents are now obese, predisposing 17% of our nation's youth to metabolic complications of obesity, such as type 2 diabetes (T2D). Adolescent obesity has tripled over the last three decades in the setting of food advertising directed at children. Obese adults exhibit increased brain responses to food images in motivation-reward pathways. These neural alterations may be attributed to obesity-related metabolic changes, which promote food craving and high-calorie food (HCF) consumption. It is not known whether these metabolic changes affect neural responses in the adolescent brain during a crucial period for establishing healthy eating behaviors. Twenty-five obese (BMI 34.4 kg/m2, age 15.7 years) and fifteen lean (BMI 20.96 kg/m2, age 15.5 years) adolescents underwent functional MRI during exposure to HCF, low-calorie food (LCF), and nonfood (NF) visual stimuli 2 h after isocaloric meal consumption. Brain responses to HCF relative to NF cues increased in obese versus lean adolescents in striatal-limbic regions (i.e., putamen/caudate, insula, amygdala) (P < 0.05, family-wise error [FWE]), involved in motivation-reward and emotion processing. Higher endogenous leptin levels correlated with increased neural activation to HCF images in all subjects (P < 0.05, FWE). This significant association between higher circulating leptin and hyperresponsiveness of brain motivation-reward regions to HCF images suggests that dysfunctional leptin signaling may contribute to the risk of overconsumption of these foods, thus further predisposing adolescents to the development of obesity and T2D. © 2014 by the American Diabetes Association.

The aim of this research is to assess the body composition and the level of physical activity by euthophic and obese adolescents classified by the growth curve of the World Health Organization, 2006 in Brazil (WHO, 2006). Methods: 29 adolescents were selected aged between 11 and 15 years from state schools of Ribeirão Preto- SP- Brazil. Nineteen are euthophic and 10 are obese. Weight, height, waist and hip circumference and electric bioimpedance were measured it. To assess physical activity it was used accelerometer (activPAL®, Glasgow, UK) for 7 days and IPAQ questionnaire. It was also evaluated eating habits by the food behavior questionnaire. Results: BMI mean for obese was 29.40 kg/m² and 21.27 kg/m² for the eutrophic. The obese adolescents classified by BMI showed higher mean fat mass by electric bioimpedance when compared to euthophic adolescents, 38.6% versus 26%, respectively. The relation waist/hip circumference was higher in the obese group than in the euthophic (0.85 for obese and 0.71 for euthophic). Reading to high cardio vascular risk above 0.8. The level of physical inactivity by IPAQ was 89.5% for the euthophic and 80% for the obese. The inactivity classification was determined by those individuals who did less than 300 minutes of physical activity per week. The results of the accelerometer did not show statistical difference in the activities performed by the obese and eutrophic. These activities are the time spend sitting, walking and standing. 63% of the euthophic and 60% of the obese have the habit of watching television while eating. Conclusion: Adolescents have the same profile

    Obesity is now common and this may have altered visual perceptions of what constitutes a 'normal' and therefore healthy weight. The present study examined cross-cultural differences in male and female participants' ability to visually identify the weight status of photographed Caucasian males. Five hundred and fifty three male and female young adults from the US (high obesity prevalence), UK and Sweden (lower obesity prevalence) participated in an online study. Participants judged the weight status of a series of photographed healthy weight, overweight and obese (class I) Caucasian males and rated the extent to which they believed each male should consider losing weight. There was a strong tendency for both male and female participants to underestimate the weight status of the photographed overweight and obese males. Photographed males were frequently perceived as being of healthier weight than they actually were. Some modest cross-cultural differences were also observed; US participants were worse at recognising obesity than UK participants (p cross-cultural differences were observed for perceptions or attitudes towards the photographed healthy weight or overweight males. The weight status of overweight and obese (class I) Caucasian males is underestimated when judged by males and females using visual information alone. This study provides initial evidence of modest cross-cultural differences in attitudes toward, and the ability to recognise, obesity in Caucasian males.

    Obesity is a major global burden. Low levels of physical activity, TV watching, and dietary pattern are modifiable risk factors for overweight and obesity in adolescent. The objective of this study was to determine risk factors for overweight and obesity among affluent adolescent, in Surat city in south Gujarat. Cross sectional from July 2009 to April 2010. Two private schools with tuition fees more than Rs. 2000 per month, were selected randomly using a random table. The participants were adolescents, 12 to 15 years of age. Pre-designed and pre-tested questionnaire was used to elicit the information about dietary history and physical activity. Height and weight was measured and BMI was calculated. Overweight and obesity were assessed by BMI for age. Student who had BMI for age <85(th) and <95(th) percentile of reference population were classified as overweight and BMI for age <95(th) percentile of reference population were classified as obese (IAP Growth Monitoring Guidelines for Children from Birth to 18 Year). The overall prevalence of obesity and overweight was 6.55% and 13.9% (boys: 6.7% and 15.1%; girls 6.4% and 13.35%). Final model of multiple logistic regression analysis showed that important determinants of overweight and obesity were low levels of physical activity, watching television or playing computer games, and consuming junk foods, snacks and carbonated drinks. The magnitude of obesity and overweight among affluent adolescent of Surat city was found to be 6.55% and 13.9%, respectively. Low level of physical activity, watching TV or playing computer games, and dietary pattern predisposed the adolescent to overweight/obesity.

    To generate prevalence estimates of weight status and cardiometabolic disease risk factors among adolescents with and without disabilities. Analysis of the 1999-2010 National Health and Nutrition Examination Survey data was conducted among 12-18 years old with (n = 256) and without disabilities (n = 5020). Mean values of waist circumference, fasting glucose, high-density-lipoprotein cholesterol, triglycerides, systolic and diastolic blood pressure and metabolic syndrome (MetS, ≥ 3 risk factors present) were examined by the following standardized body mass index (BMI) categories for those with and without disabilities; overweight (BMI ≥ 85(th) - obesity (BMI ≥ 95(th) percentile) and severe obesity (BMI ≥35 kg/m(2)). Linear regression models were fit with each cardiometabolic disease risk factor independently as continuous outcomes to show relationships with disability status. Adolescents with disabilities were significantly more likely to be overweight (49.3%), obese (27.6%) and severely obese (12%) vs their peers without disabilities (33.1%, 17.5% and 3.6%, respectively, P ≤ 0.01 for all). A higher proportion of overweight, obese and severely obese children with disabilities had abnormal SBP, fasting lipids and glucose as well as MetS (18.9% of overweight, 32.3% of obese, 55% of severely obese) vs their peers without disabilities (9.7%, 16.8%, 36.3%, respectively). US adolescents with disabilities are over three times as likely to have MetS (OR = 3.45, 95%CI: 1.08-10.99, P = 0.03) vs their peers with no disabilities. Results show that adolescents with disabilities are disproportionately affected by obesity and poor cardiometabolic health vs their peers with no disabilities. Health care professionals should monitor the cardiometabolic health of adolescents with disabilities.

    Objectives Prevention of obesity should start as early as possible after birth. We aimed to build clinically useful equations estimating the risk of later obesity in newborns, as a first step towards focused early prevention against the global obesity epidemic. Methods We analyzed the lifetime Northern Finland Birth Cohort 1986 (NFBC1986) (N = 4,032) to draw predictive equations for childhood and adolescent obesity from traditional risk factors (parental BMI, birth weight, maternal gestational weight gain, behaviour and social indicators), and a genetic score built from 39 BMI/obesity-associated polymorphisms. We performed validation analyses in a retrospective cohort of 1,503 Italian children and in a prospective cohort of 1,032 U.S. children. Results In the NFBC1986, the cumulative accuracy of traditional risk factors predicting childhood obesity, adolescent obesity, and childhood obesity persistent into adolescence was good: AUROC = 0·78[0·74–0.82], 0·75[0·71–0·79] and 0·85[0·80–0·90] respectively (all pchildhood obesity remained acceptably accurate when applied to the Italian and the U.S. cohort (AUROC = 0·70[0·63–0·77] and 0·73[0·67–0·80] respectively) and the two additional equations for childhood obesity newly drawn from the Italian and the U.S. datasets showed good accuracy in respective cohorts (AUROC = 0·74[0·69–0·79] and 0·79[0·73–0·84]) (all pchildhood obesity were converted into simple Excel risk calculators for potential clinical use. Conclusion This study provides the first example of handy tools for predicting childhood obesity in newborns by means of easily recorded information, while it shows that currently known genetic variants have very little usefulness for such prediction.

    BACKGROUND: The high injury incidence during match-play in female adolescent football is a major concern. In football, males and females play matches with the same football size. No studies have investigated the effect of football size on injury incidence in female adolescent football. Thus......, the aim of the present study was to investigate the effects of introducing a lighter, smaller football on the injury pattern in female adolescent football. METHODS We conducted a pilot cluster randomized controlled trial including 26 football teams representing 346 adolescent female football players (age...... 15-18 years). The teams were randomized to a new lighter, smaller football (INT, N.=12 teams) or a traditional FIFA size 5 football (CON, N.=14 teams) during a full match-season. Acute time-loss injuries and football-exposure during match-play were reported weekly by text-message questions...

    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.

    Full Text Available The discrete effects of obesity on infertility in females remain undefined to date. To investigate obesity-induced ovarian dysfunction, we characterized metabolic parameters, steroidogenesis, and folliculogenesis in obese and lean female Ossabaw mini-pigs. Nineteen nulliparous, sexually mature female Ossabaw pigs were fed a high fat/cholesterol/fructose diet (n=10 or a control diet (n=9 for eight months. After a three-month diet-induction period, pigs remained on their respective diets and had ovarian ultrasound and blood collection conducted during a five-month study period after which ovaries were collected for histology, cell culture, and gene transcript level analysis. Blood was assayed for steroid and protein hormones. Obese pigs developed abdominal obesity and metabolic syndrome, including hyperglycemia, hypertension, insulin resistance and dyslipidemia. Obese pigs had elongated estrous cycles and hyperandrogenemia with decreased LH, increased FSH and luteal phase progesterone, and increased numbers of medium, ovulatory, and cystic follicles. Theca cells of obese, compared to control, pigs displayed androstenedione hypersecretion in response to in vitro treatment with LH, and up-regulated 3-beta-hydroxysteroid dehydrogenase 1 and 17-beta-hydroxysteroid dehydrogenase 4 transcript levels in response to in vitro treatment with LH or LH + insulin. Granulosa cells of obese pigs had increased 3-beta-hydroxysteroid dehydrogenase 1 transcript levels. In summary, obese Ossabaw pigs have increased transcript levels and function of ovarian enzymes in the delta 4 steroidogenic pathway. Alterations in LH, FSH, and progesterone, coupled with theca cell dysfunction, contribute to the hyperandrogenemia and disrupted folliculogenesis patterns observed in obese pigs. The obese Ossabaw mini-pig is a useful animal model in which to study the effects of obesity and metabolic syndrome on ovarian function and steroidogenesis. Ultimately, this animal model may be

    To determine if urinary symptoms or urinary tract infections (UTI) were associated with sexually transmitted infections (STI) and which history, clinical, and laboratory findings could distinguish these infections in symptomatic women. A cross-sectional sample of 296 sexually active females aged 14-22 years attending a hospital-based teen health center or emergency department were recruited. Genitourinary symptoms, medical and sexual history, and urinalysis results were recorded. STI was defined as a vaginal swab positive for Trichomonas vaginalis or urine nucleic acid amplification test positive for Neisseria gonorrheae or Chlamydia trachomatis. A urine culture with >10,000 colonies of a single pathogen was considered a positive UTI. In the full sample, prevalence of UTI and STI were 17% and 33%, respectively. Neither urinary symptoms nor UTI was significantly associated with STI. Further analyses are reported for the 154 (51%) with urinary symptoms: Positive urine leukocytes, more than one partner in the last three months and history of STI predicted STI. Urinalysis results identified four groups: (1) Normal urinalysis-67% had no infection; (2) Positive nitrites or protein-55% had UTI; (3) Positive leukocytes or blood-62% had STI; and (4) Both nitrites/protein and leukocytes/blood positive-28% had STI and 65% had UTI. Those without a documented UTI were more likely to have trichomoniasis than those with a UTI, and 65% of those with sterile pyuria had STI, mainly trichomoniasis or gonorrhea. Adolescent females with urinary symptoms should be tested for both UTI and STIs. Urinalysis results may be helpful to direct initial therapy.

    The purpose of this study was to explore the prevalence and correlates of eating disorders among a community-based sample of female Chilean adolescents. Data were collected through structured interviews with 420 female adolescents residing in Santiago, Chile. Approximately 4% of the sample reported ever being diagnosed with an eating disorder. Multivariate logistic regression analyses revealed that those with higher symptoms of anxiety and who had tried cigarettes were significantly more likely to have been diagnosed with an eating disorder. Findings indicate that Chilean female adolescents are at risk of eating disorders and that eating disorders, albeit maladaptive, may be a means to cope with negative affect, specifically anxiety.

    Within the Self-Determination Theory (SDT) framework, the first major study aim was to investigate the SDT tenets in an obese adolescent population by examining the factor structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) and by investigating associations between physical activity (PA) and motivation in obese adolescents. The second aim was to study differences in motivation according to adolescents' educational level, since lower educated obese adolescent are a sub-risk group for lower PA levels among the obese adolescents. The third aim was to investigate whether attending a residential obesity treatment program could lead to an increase in autonomous motivation towards PA and to see if the treatment effect on motivation was different in low versus high educated youth. For the first study aim, the sample comprised 177 obese adolescents at the start of a 10-month multidisciplinary residential obesity treatment program (BMI = 35.9 ± 6.0 kg/m², 15.1 ± 1.5 years, 62% girls). A subsample of 65 adolescents (stratified by educational level) were divided into low (n = 34) versus high educated (n = 31) as part of the second and third study aim. Motivation was assessed using the BREQ-2 and PA using the Flemish Physical Activity Questionnaire. Exploratory factor analysis showed sufficient validations with the original factor for 17 out of 19 BREQ-2 items. Significant positive correlations were found between PA and the composite score of relative autonomy (r = 0.31, p intrinsic regulation (r = 0.38, p educated adolescents scored higher on the composite score of relative autonomy, introjected, identified and intrinsic regulation at the start of treatment (F = 3.68, p intrinsic regulation significantly increased during treatment for all adolescents (F = 6.65, p educated adolescents (F = 25.57, p motivation towards PA were related to higher PA levels. Adolescents had increases in both autonomous and controlled forms of motivation during treatment

The present study investigates whether weight reduction influences aortic stiffness in obese children and adolescents. Carotid-femoral pulse wave velocity (cfPWV) and augmentation index at heart...... was found in AIx@HR75 (Delta AIx@HR75: 2.10 +/- 9.73%, P = 0.072), but changes in AIx@HR75 were related to changes in abdominal fat (Delta waist/height ratio: beta = 50.3, 95% CI 6.7-94.0, P = 0.02) and changes in total body fat percent by dual energy X-ray absorptiometry scan (Delta total body fat...... (%): beta = 0.7, 95% CI 0.1-1.3, P = 0.02) when adjusted for gender and relevant baseline confounders. In conclusion, no clear effect of weight reduction was found on aortic stiffness, although changes in AIx@HR75 were associated with changes in both abdominal fat and total body fat percent.

    Full Text Available Abstract Background Obesity is a chronic disease associated to an inflammatory process resulting in oxidative stress that leads to morpho-functional microvascular damage that could be improved by some dietary interventions. In this study, the intake of Brazil nuts (Bertholletia excelsa, composed of bioactive substances like selenium, α- e γ- tocopherol, folate and polyunsaturated fatty acids, have been investigated on antioxidant capacity, lipid and metabolic profiles and nutritive skin microcirculation in obese adolescents. Methods Obese female adolescents (n = 17, 15.4 ± 2.0 years and BMI of 35.6 ± 3.3 kg/m2, were randomized 1:1 in two groups with the diet supplemented either with Brazil nuts [BNG, n = 08, 15-25 g/day (equivalent to 3 to 5 units/day] or placebo [PG (lactose, n = 09, one capsule/day] and followed for 16 weeks.

    Malaysians have become increasingly obese over recent years. The transition from adolescence to early adulthood is recognized as critical for the development of eating and activity habits. However, little obesity-related research focuses on this life stage. Drawing on data from a health and demographic surveillance site in Malaysia, this article describes obesity and overweight amongst adolescents and young adults in a multi-ethnic population. Data were collected at the South East Asia Community Observatory (SEACO) in Segamat District, Johor. In this dynamic cohort of approximately 40,000 people, 5,475 were aged 16-35 in 2013-2014. The population consists of Malay, Chinese, Indian and Indigenous (Orang Asli) families in proportions that reflect the national ethnic diversity. Data were collected through health profiles (Body Mass Index [BMI] measurements in homes) and self-report questionnaires. Age and ethnicity were associated with overweight (BMI 25.0-29.9Kg/m 2 ) and obesity (BMI ≥ 30Kg/m 2 ). The prevalence of overweight was 12.8 % at ages 16-20 and 28.4 % at ages 31-35; obesity was 7.9 % and 20.9 % at the same age groups. The main ethnic groups also showed varied patterns of obesity and overweight at the different age groups with Chinese at lowest and Orang Asli at highest risk. Level of education, employment status, physical activity and frequency of eating out were poorly predictive of overweight and obesity. The pattern of overweight and obesity in the 16-35 age group further highlights this as a significant period for changes in health-related behaviours. Further longitudinal research is however needed to confirm the observed pattern and investigate causal factors.

    Full Text Available Obesity is one of the greatest health challenges facing today’s adolescents. Dietary interventions are the foundation of obesity prevention and management. As adolescents are digital frontrunners and early adopters of technology, digital health interventions appear the most practical modality for dietary behavior change interventions. Despite the rapid growth in digital health interventions, effective engagement with adolescents remains a pertinent issue. Key strategies for effective engagement include co-designing interventions with adolescents, personalization of interventions, and just-in-time adaptation using data from wearable devices. The aim of this paper is to appraise these strategies, which may be used to improve effective engagement and thereby improve the dietary behaviors of adolescents now and in the future.

    To develop and crossvalidate new equations for predicting basal metabolic rate (BMR) in obese children and adolescents in relation to pubertal stages, anthropometric characteristics or body composition. A total of 1696 obese Caucasian children and adolescents (mean body mass index z-score: 3.5±0.8) participated in this study. BMR was determined by indirect calorimetry and fat-free mass (FFM) and fat mass (FM) by bioelectrical impedance analysis. Equations were derived by stepwise multiple regression analysis using a calibration cohort of 848 subjects, and the equations were crossvalidated with a Bland and Altman method in the remaining 848 subjects. Two new specific equations based on gender (1: males; 0: females), pubertal stages (from 1 to 5, assessed according Marshall & Tanner methods) and body weight (BW, kg), stature (m) or body composition (kg) were generated as follows: (1) BMR=(BW × 0.044)+(stature × 2.836)-(pubertal stage × 0.148)+(gender × 0.781)-0.551 (adjusted coefficient of determination (R(2)adj)= 0.69 and root mean squared error (RMSE)=0.954 MJ); (2) BMR=(FFM × 0.082)+(FM × 0.037)-(pubertal stage × 0.125)+(gender × 0.706)+2.528 (R(2)adj= 0.70 and RMSE=0.943 MJ). In the crossvalidation group, mean-predicted BMR was not significantly different from the mean-measured BMR (MBMR) for all children and adolescents, as well as for boys and girls (differenceBMR was predicted accurately (90-110% of MBMR) in 67% of subjects. The new prediction equations considering the pubertal stages allow an accurate and more appropriate (vs equations using chronological age) estimation of BMR in obese children and adolescents.

    This study was aimed to examine if adolescent obesity is associated with alterations of insula function as indexed by differential correlations between insula activation and perception of interoceptive feedback versus external food cues. We hypothesized that, in healthy weight adolescents, insula activation will positively correlate with interoceptive sensitivity, whereas in excess weight adolescents, insula activation will positively correlate with sensitivity towards external cues. Fifty-four adolescents (age range 12-18), classified in two groups as a function of BMI, excess weight (n = 22) and healthy weight (n = 32), performed the Risky-Gains task (sensitive to insula function) inside an fMRI scanner, and completed the heartbeat perception task (measuring interoceptive sensitivity) and the Dutch Eating Behaviour Questionnaire (measuring external eating as well as emotional eating and restraint) outside the scanner. We found that insula activation during the Risky-Gains task positively correlated with interoceptive sensitivity and negatively correlated with external eating in healthy weight adolescents. Conversely, in excess weight adolescents, insula activation positively correlated with external eating and negatively correlated with interoceptive sensitivity, arguably reflecting obesity related neurocognitive adaptations. In excess weight adolescents, external eating was also positively associated with caudate nucleus activation, and restrained eating was negatively associated with insula activation. Our findings suggest that adolescent obesity is associated with disrupted tuning of the insula system towards interoceptive input. Copyright © 2015 Elsevier Ltd. All rights reserved.

    This study aimed to explore the socio-demographic and dietary factors that may be associated with obesity among female university students in Jordan. A cross-sectional survey was carried out among 406 female students recruited from two universities in Jordan. Data were collected through self-reporting, using a previously validated questionnaire. Weight and height were measured and body mass index was calculated to determine the weight status of the participants. High educational level of mothers [odds ratio (OR)=1.25] and monthly pocket money of more than 200 Jordanian Dinars (OR=1.67) were found to be risk factors for obesity, whereas a sibling ranking of more than six was a protective factor (OR=0.31). Those who were eating from the university cafeteria had double the risk for obesity (OR=2.41) than those who did not. Regular eating of meals and snacking between meals were found to be protective factors (OR ranged from 0.42 to 0.79). Regular consumption of milk products, fruit, canned fruit juices, bakery products and legumes were found to be protective factors. In contrast, the regular consumption of potato chips (OR=1.35), chicken (OR=1.51), and fish (OR=1.45) were found to be risk factors for obesity. Using a chi-square test, none of the factors studied showed significant association with obesity. A program to promote healthy eating among university students in Jordan should consider the local socio-demographic and food behavior factors that could be related to obesity to ensure the effectiveness of such a program.

    Background and Purpose Irisin is an exercise-responsive myokine that has been proposed to exert anti-obesity benefits; yet its response during exercise in obese women is not described. This study characterized plasma irisin levels during a single bout of afternoon isocaloric-exercise of different intensities (moderate- vs high-intensity) in obese females. Methods Eleven obese females participated in 3 randomized study days beginning at 1600h: 1) no exercise (NoEx), 2) moderate exercise (ModEx; 55%VO2max) and 3) high intensity interval exercise (IntEx; 4 min (80%VO2max)/3 min (50% VO2max). Frequent blood samples were analyzed for glucose and lactate (whole-blood), and insulin, c-peptide, glucagon, and irisin (plasma) throughout 190 min of testing. Results Plasma irisin increased above baseline during ModEx and IntEx (P0.05). Peak irisin levels during ModEx and IntEx exercise were 11.9± 3.4% and 12.3 ± 4.1% relative to baseline (Pexercise intensities (P>0.05). Irisin levels remained elevated above resting for 125 minutes post-exercise during ModEx, whereas levels returned to baseline within 15 minutes post-exercise during IntEx. Similarly, no associations were found between plasma irisin levels and circulating lactate, glucose, insulin, c-peptide, or glucagon among study days (P>0.05). However, there was an inverse association between basal irisin and lean mass (r = -0.70, P = 0.01). Conclusion A single bout of moderate and high intensity afternoon exercise induces modest increases in circulating irisin concentrations during exercise; however the regulation post-exercise appears to be dimorphic between exercise intensity in obese females. Future studies are needed to compare morning and afternoon exercise on irisin secretion. PMID:28125733

    To evaluate the effect of Go4it, a multidisciplinary group education programme for adolescents with overweight or obesity. Uncontrolled intervention study. At the obesity outpatient clinic of the Transmural Research and Treatment Centre for Overweight and Obese Children of the VU University Medical Center, Amsterdam, The Netherlands, a group education programme was developed for adolescents (age 12-18 year) who are overweight or obese. Obese adolescents who were referred to the obesity outpatient clinic were asked to participate. During 7 sessions (one session every two weeks) the adolescents were educated on the health consequences of obesity, diet, physical activity, energy balance, improving self-esteem and how to handle bullying and other difficult situations. All sessions were held in groups of 8-10 adolescents. In addition, two sessions were organised for the parents concerning the health consequences of obesity, diet, and physical activity. Body weight and height, glucose tolerance (by an oral glucose tolerance test; OGTT), and insulin resistance were measured at enrolment into the Go4it programme and 6 months later. In total, 93 adolescents (39 boys, 54 girls) were included with a mean age of 3.9 (SD: 1.7) years. Of those, 69 adolescents (74%) attended at least 6 out of 7 sessions of the education programme. Stabilisation or reduction in obesity levels following completion of Go4it was achieved in 51 (74%) of these participants. 50 adolescents had a second OGTT. The BMI standard deviation score (BMI-sds) decreased by 4.3% for boys (p = 0.020) and 3.3% for girls (p = 0.017). Among girls, fasting blood glucose levels decreased by an average of 0.37 mmol/l (95% CI: 0.14-0.60) and insulin concentrations decreased by an average of 299 pmol/l (95% CI: 71-528). Participation in the Go4it education programme is accompanied by a stabilisation or reduction in the level of obesity and has favourable effects on glucose and insulin metabolism.

    Full Text Available Abstract Background Environment, health behavior, and genetic background are important in the development of obesity. Adolescents spend substantial part of daily leisure time on cultural and social activities, but knowledge about the effects of participation in such activities on weight is limited. Methods A number of 1450 adolescents from the Norwegian HUNT study (1995–97 were followed-up in 2006–08 as young adults. Phenotypic data on lifestyle and anthropometric measures were assessed using questionnaires and standardized clinical examinations. Genotypic information on 12 established obesity-susceptibility loci were available for analyses. Generalized estimating equations were used to examine the associations between cultural and social activities in adolescence and adiposity measures in young adulthood. In addition, interaction effects of a genetic predisposition score by leisure time activities were tested. Results In girls, participation in cultural activities was negatively associated with waist circumference (WC (B = −0.04, 95%CI: -0.08 to −0.00 and with waist-hip ratio (WHR (B = −0.058, 95%CI: -0.11 to −0.01. However, participation in social activities was positively associated with WC (B = 0.040, CI: 0.00 to 0.08 in girls and with BMI (B = 0.027, CI: 0.00 to 0.05 in boys. The effect of the obesity-susceptibility genetic variants on anthropometric measures was lower in adolescents with high participation in cultural activities compared to adolescents with low participation. Conclusion This study suggests that the effects of cultural activities on body fat are different from the effects of participation in social activities. The protective influence of cultural activities in female adolescents against overweight in adulthood and their moderating effect on obesity-susceptibility genes suggest that even cultural activities may be useful in public health strategies against obesity.

    The Working Group of Obesity in Childhood and Adolescence (AGA) comprises scientists, clinicians, and therapists dealing with obesity in children and adolescents. More than 250 pediatricians, psychiatrics, dieticians, psychologists and sports therapists are integrated. On an international level, the AGA cooperates with the European Childhood Obesity Group and the International Obesity Taskforce (IOTF) for Childhood Obesity. The aims of the AGA are to initiate clinical and scientific studies, to join diagnostic, therapeutic and scientific centers, to improve the education, to support self-help groups, and to standardize diagnostic and therapeutic procedures in the field of obesity in childhood and adolescence. The milestones in the history of the AGA are the consensus process to define overweight and obesity in Germany, the development of guidelines for diagnostic procedures and treatment of obesity in childhood and adolescence, the determination of all therapy centers for obese children and adolescents in Germany, the development of a PC software (APV) to document longitudinally diagnostic and therapeutic procedures as well as outcomes by a quality management program, the certification of therapeutic institutions, and the implementation of prevention and treatment studies. As effect of these initiatives, the quality of care in overweight children has been improved in the last years. For example, the APV quality program demonstrated an increase of diagnostic procedures such as blood pressure measurement in the last 4 years. Copyright 2008 S. Karger AG, Basel.

    Accurate estimation of resting energy expenditure (REE) in childrenand adolescents is important to establish estimated energy requirements. The aim of the present study was to measure REE in obese children and adolescents by indirect calorimetry method, compare these values with REE values estimated by equations, and develop the most appropriate equation for this group. One hundred and three obese children and adolescents (57 males, 46 females) between 7 and 17 years (10.6 ± 2.19 years) were recruited for the study. REE measurements of subjects were made with indirect calorimetry (COSMED, FitMatePro, Rome, Italy) and body compositions were analyzed. In females, the percentage of accurate prediction varied from 32.6 (World Health Organization [WHO]) to 43.5 (Molnar and Lazzer). The bias for equations was -0.2% (Kim), 3.7% (Molnar), and 22.6% (Derumeaux-Burel). Kim's (266 kcal/d), Schmelzle's (267 kcal/d), and Henry's equations (268 kcal/d) had the lowest root mean square error (RMSE; respectively 266, 267, 268 kcal/d). The equation that has the highest RMSE values among female subjects was the Derumeaux-Burel equation (394 kcal/d). In males, when the Institute of Medicine (IOM) had the lowest accurate prediction value (12.3%), the highest values were found using Schmelzle's (42.1%), Henry's (43.9%), and Müller's equations (fat-free mass, FFM; 45.6%). When Kim and Müller had the smallest bias (-0.6%, 9.9%), Schmelzle's equation had the smallest RMSE (331 kcal/d). The new specific equation based on FFM was generated as follows: REE = 451.722 + (23.202 * FFM). According to Bland-Altman plots, it has been found out that the new equations are distributed randomly in both males and females. Previously developed predictive equations mostly provided unaccurate and biased estimates of REE. However, the new predictive equations allow clinicians to estimate REE in an obese children and adolescents with sufficient and acceptable accuracy.

    Full Text Available This study aimed to investigate the association of overweight and obesity with hypertension in adolescents from public schools in Curitiba, southern Brazil.The sample comprised 1,549 randomly selected adolescents aged 12 to 18 years (744 males. Body mass index (BMI was calculated and classified according to Conde and Monteiro (2006. Blood pressure was measured by the auscultation method on two occasions (different days and was classified according to the fourth report of the National High Blood Pressure Education Program (NHBPEP. Prevalence ratio was used as a measure of association. Overweight and obesity were observed in 23% and 5.8% of boys, respectively. Among girls, 18.8% were overweight and 5.6% were obese. After two measurements, 7% of boys had prehypertension and 10.5% had hypertension. Pre hypertension and hypertension were observed in 5.2% and 9.9% of girls, respectively. Obesity was significantly associated with high blood pressure among boys (PR = 1.19, 95% CI= 1.07-1.32. Overweight (PR = 1.11, 95% CI = 1.04-1.17 and obese (PR = 1.26,95% CI = 1.13-1.40 girls were more likely to have high blood pressure levelsin comparison to normal weight adolescents. These results showed alarming estimates of hypertension among young people and that the reduction of obesity during adolescence should be focused on public policies for hypertensionprevention in the population.

    To assess subclinical kidney injury in adolescents with severe obesity by measuring biomarkers of early kidney disease and to assess changes in the levels of these biomarkers following bariatric procedures. Twenty-two adolescents undergoing bariatric surgery with no microalbuminuria and normal kidney function were selected. Urinary NGAL, IL-18, and KIM-1 were measured at baseline, 6 and 12 months postoperatively. Biomarker levels were compared to 44 age-gender-matched lean controls. Subjects with obesity had a mean baseline BMI of 48 kg/m(2) that decreased by 34% at 1-year follow-up. Urine NGAL, IL-18, and KIM-1 were significantly elevated in subjects with obesity compared to lean controls at baseline. The obese cohort had a further significant increase in NGAL and KIM-1 at 6 months, followed by decline at 1 year. The overall change in levels of all three biomarkers through 1 year after surgery, however, was not significant compared to baseline. Adolescent severe obesity is associated with increased urinary excretion of novel biomarkers of kidney injury, despite no microalbuminuria or decreased kidney function. This subclinical kidney injury persists 1 year after significant weight loss induced by bariatric surgery, suggesting that close, long-term follow-up of kidney status is warranted in these adolescents. © 2015 The Obesity Society.

    Overweight and obesity are afflictions that lead to an increased risk of health problems including joint problems. The aim of the study was to assess the condition of articular cartilage in obese adolescent patients suffering from knee pain. MRI of 24 knees of 20 morbidly obese patients, mean age 14.2 years, was performed in an open 1.0 Tesla MR system, where the cartilage, the quality and structure of the menisci, and the presence or absence of surrounding changes was examined. In all patients a cartilage lesion in at least one region of the knee could be detected. Retropatellar cartilage lesions have been found in 19 knees. Ten cartilage lesions grade I, and four lesions grade II have been described in the lateral compartment of the knee, whereas the medial compartment showed in eight cases a grade I, in 13 cases a grade II and in two cases a grade III cartilage lesion. Meniscal changes were assessed in most patients. Morbidly obese children and adolescents show major abnormalities in the articular cartilage of the knee. Whether obesity alone is the causal factor for the development of the pattern of these changes, remains to be seen. (orig.)

    Objective To investigate the association between obesity and multiple sclerosis (MS) while accounting for established genetic and environmental risk factors. Methods Participants included members of Kaiser Permanente Medical Care Plan, Northern California Region (KPNC) (1,235 MS cases and 697 controls). Logistic regression models were used to estimate odds ratios (ORs) with 95% confidence intervals (95% CI). Body mass index (BMI) or body size was the primary predictor of each model. Both incident and prevalent MS cases were studied. Results In analyses stratified by gender, being overweight at age 10 and 20 were associated with MS in females (prisk of MS for females with a BMI ≥ 30 kg/m2 was observed (OR = 2.15, 95% CI 1.18, 3.92). Significant associations between BMI in 20’s and MS in males were not observed. Multivariate modeling demonstrated that significant associations between BMI or body size with MS in females persisted after adjusting for history of infectious mononucleosis and genetic risk factors, including HLA-DRB1*15:01 and established non-HLA risk alleles. Interpretation Results show that childhood and adolescence obesity confer increased risk of MS in females beyond established heritable and environmental risk factors. Strong evidence for a dose-effect of BMI in 20’s and MS was observed. The magnitude of BMI association with MS is as large as other known MS risk factors. PMID:25263833

    There is mounting evidence that family functioning is linked to childhood overweight and obesity, and that both of these are associated with health-related behaviours and adverse health outcomes in children and adolescents. This paper systematically examines the peer-reviewed evidence regarding the relationship between child and adolescent overweight and obesity and family functioning. Peer-reviewed literature published between 1990 and 2011 hosted in Scopus, Pub Med or Psyc INFO were searched, in addition to the reference lists of included papers. Twenty-one studies met the selection criteria. Of the 17 identified cross-sectional and longitudinal studies, 12 reported significant associations between family functioning and childhood overweight and obesity. The instruments used to measure family functioning in the identified studies were heterogeneous. Poor family functioning was associated with increased risk of obesity and overweight in children and adolescents, and obese children and adolescents were more likely to come from families with poor family functioning. Aspects of family functioning which were associated with increased risk of child and adolescent obesity included poor communication, poor behaviour control, high levels of family conflict and low family hierarchy values. Half (2/4) of the identified intervention studies showed a significant relationship between family functioning and changes in child weight. The results demonstrate that family functioning is linked to obesity; however, higher level evidence and greater understanding of the mechanisms behind this relationship are required. The results indicate a need for a standardised family functioning measure applicable across populations. The results provide evidence of the value of considering family functioning in childhood obesity research and intervention.

    The ever increasing epidemics of overweight and obesity in school children may be one of the reasons of the growing numbers of children with incorrect body posture. The purpose of the study was the assessment of the prevalence of incorrect body posture in children and adolescents with overweight and obesity in Poznań, Poland. The population subject to study consisted of 2732 boys and girls aged 3-18 with obesity, overweight, and standard body mass. The assessment of body mass was performed based on BMI, adopting Cole's cutoff values. The evaluation of body posture was performed according to the postural error chart based on criteria complied by professor Dega. The prevalence rates of postural errors were significantly higher among children and adolescents with overweight and obesity than among the group with standard body mass. In the overweight group, it amounted to 69.2% and in the obese group to 78.6%.  The most common postural deviations in obese children and adolescents were valgus knees and flat feet. Overweight and obesity in children and adolescents, predisposing to higher incidence of some types of postural errors, call for prevention programs addressing both health problems. What is Known: • The increase in the prevalence of overweight and obesity among children and adolescents has drawn attention to additional health complications which may occur in this population such as occurrence of incorrect body posture. What is New: • The modified chart of postural errors proved to be an effective tool in the assessment of incorrect body posture. • This chart may be used in the assessment of posture during screening tests and prevention actions at school.

    The purpose of the present paper was to assess dietary energy reporting as a function of sex and weight status among Ontario and Alberta adolescents, using the ratio of energy intake (EI) to estimated BMR (BMRest). Data were collected using the FBQ, a validated web-based dietary assessment tool (including a 24 h dietary recall, FFQ, and food and physical activity behavioural questions). BMI was calculated from self-reported height and weight and participants were classified as normal weight, overweight or obese. BMR was calculated using the WHO equations (based on weight). Reporting status was identified using the ratio EI:BMRest. Data were collected in public, Catholic and private schools in Ontario and Alberta, Canada. A total of 1917 (n 876 male and n 1041 female) students (n 934 grade 9 and n 984 grade 10) participated. The mean EI:BMRest ratio across all participants was 1.4 (sd 0.6), providing evidence of under-reporting for the total sample. Females under-reported more than males (t = 6.27, P < 0.001), and under-reporting increased with increasing weight status for both males (F = 33.21, P < 0.001) and females (F = 14.28, P < 0.001). After removing those who reported eating less to lose weight, the EI:BMRest was 1.56 (sd 0.6) for males and 1.4 (sd 0.6) for females. The present study highlights methodological challenges associated with self-reported dietary data. Systematic differences in under-reporting of dietary intake by gender and weight status were observed using a web-based survey, similar to observations made using paper-based 24 h recalls and dietitian interviews.

    Approximately 5–10% of subjects with prediabetes become diabetic every year. Inflammation is involved in the development of obesity-related type 2 diabetes (T2D). However, to date, the relationship between inflammation and prediabetes, defined by hemoglobin A1c (HbA1c) ≥ 5.7 and prediabetes. A total of 21 otherwise healthy, overweight/obese, young adult African American females with prediabetes, together with 20 matched overweight/obese controls, were selected for this study. Plasma cytokines were assessed by multiplex cytokine profiling. Plasma concentrations of interleukin (IL)-5, IL-6, IL-7, tumor necrosis factor-α (TNF-α), and granulocyte-monocyte colony-stimulating factor (GM-CSF) were significantly higher in the prediabetic group, as compared to the control group (all p prediabetic group, but failed to reach statistical significances. Upon merging both groups, HbA1c was found to be positively correlated with IFN- γ, IL-1β, IL-2, IL-5, IL-7, IL-8, TNF-α and GM-CSF. This study demonstrates elevated levels of various pro-inflammatory cytokines in overweight/obese young subjects with prediabetes, which place them at higher risk of developing T2D and cardiovascular diseases. Our data also call for further investigations in animal models and population cohorts to establish the roles of a variety of pro-inflammatory cytokines in the early development of obesity-related T2D.

    The two-way relationship between obesity and socioeconomic disadvantage is well established but previous studies on social and economic consequences of obesity have primarily focused on relatively young study populations. We examined whether obesity is associated with socioeconomic disadvantage through the 10-12-year follow-up, and how obesity-related socioeconomic inequalities develop during midlife among women. Baseline data were derived from the female population of the Helsinki Health Study cohort, comprising 40-60 -year-old employees of the City of Helsinki, Finland in 2000-2002 (n = 6913, response rate 69%). The follow-up surveys were carried out in 2007 (n = 5810) and 2012 (n = 5400). Socioeconomic disadvantage was measured by five dichotomous measures. Repeated logistic regression analyses utilising generalized estimating equations (GEE) were used to test the association between baseline self-reported obesity and the likelihood of socioeconomic disadvantage through all phases. The effect of time on the development of inequalities was examined by time interaction terms in random effect logistic regression models. After adjustment for educational level, baseline obesity was associated with repeated poverty (OR = 1.23; 95% CI; 1.05-1.44), frequent economic difficulties (OR = 1.74; 95% CI; 1.52-1.99), low household net income (OR = 1.23; 95% CI; 1.07-1.41), low household wealth (OR = 1.90; 95% CI; 1.59-2.26) and low personal income (OR = 1.22; 95% CI; 1.03-1.44). The differences in poverty rate and low personal income between the participants with obesity and participants with normal weight widened during the follow-up. Living without a partner and early exit from paid employment explained the widening of inequalities. Weight status inequalities in socioeconomic disadvantage persisted or widened during the late adulthood.

    Skeletal muscle is a large and insulin-sensitive tissue that is an important contributor to metabolic homeostasis and energy expenditure. Many metabolic processes are altered with obesity, but the contribution of muscle tissue in this regard is unclear. A limited number of studies have compared skeletal muscle gene expression of lean and obese dogs. Using microarray technology, our objective was to identify genes and functional classes differentially expressed in skeletal muscle of obese (14.6 kg; 8.2 body condition score; 44.5% body fat) vs. lean (8.6 kg; 4.1 body condition score; 22.9% body fat) female beagle adult dogs. Alterations in 77 transcripts was observed in genes pertaining to the functional classes of signaling, transport, protein catabolism and proteolysis, protein modification, development, transcription and apoptosis, cell cycle and differentiation. Genes differentially expressed in obese vs. lean dog skeletal muscle indicate oxidative stress and altered skeletal muscle cell differentiation. Many genes traditionally associated with lipid, protein and carbohydrate metabolism were not altered in obese vs. lean dogs, but genes pertaining to endocannabinoid metabolism, insulin signaling, type II diabetes mellitus and carnitine transport were differentially expressed. The relatively small response of skeletal muscle could indicate that changes are occurring at a post-transcriptional level, that other tissues (e.g., adipose tissue) were buffering skeletal muscle from metabolic dysfunction or that obesity-induced changes in skeletal muscle require a longer period of time and that the length of our study was not sufficient to detect them. Although only a limited number of differentially expressed genes were detected, these results highlight genes and functional classes that may be important in determining the etiology of obesity-induced derangement of skeletal muscle function. © 2013 The Authors, Animal Genetics © 2013 Stichting International Foundation

Body composition was estimated via dual energy X-ray absorptiometry, fitness was assessed with maximal oxygen uptake (VO2max during treadmill test, dietary intake through 24-hour recall, questionnaires explained health behavior and fasting blood samples were taken. NWO was defined as normal BMI and body fat >17.6% in males and >31.6% in females.Among normal weight adolescents, 42% (n = 76 were defined as NWO, thereof 61% (n = 46 male participants. Fewer participants with NWO were physically active, ate breakfast on a regular basis, and consumed vegetables frequently compared with NWL. No difference was detected between the two groups in energy- and nutrient intake. The mean difference in aerobic fitness was 5.1 ml/kg/min between the groups in favor of the NWL group (p<0.001. NWO was positively associated with having one or more risk factors for metabolic syndrome (Odds Ratio OR = 2.2; 95% confidence interval CI: 1.2, 3.9 when adjusted for sex. High waist circumference was more prevalent among NWO than NWL, but only among girls (13% vs 4%, p = 0.019.High prevalence of NWO was observed in the study group. Promoting healthy lifestyle with regard to nutrition and physical activity in early life should be emphasized regardless of BMI.

    Full Text Available Xinguang Chen, Kathryn BroganPediatric Prevention Research Center, Wayne State University School of Medicine, Detroit, MI, USAObjective: To detect subgroups with different risks at different ages to develop overweight and obese during the adolescence–young adulthood period.Design: Accelerated longitudinal design and developmental trajectory analysis were used. The likelihoods to become overweight (body mass index [BMI] .25 kg/m2 and obese (BMI .30 kg/m2 were assessed across the life course from the ages of 12 to 28 years.Subjects: Adolescent participants aged 12–17 years (n = 4119 identified in the National Longitudinal Survey of Youth 1997 at baseline were followed up to 2008.Results: Seven overweight risk groups (WG were detected for male and female samples respectively, of which five were closely related to each of the following five periods: (a middle-school ages (19.7% and 12.6% for male and female, respectively, (b high-school ages (11.4% and 13.6%, respectively, (c college ages (12.6% and 9.1%, respectively, (d post-college ages (11.8% and 10.0%, respectively, and (e work–family-formation ages (11.0% and 12.9%, respectively; two were nonperiod-specific groups: a permanent low-risk group for both sexes (27.3% for male, 36.4% for female, a growing-risk group for males (6.2%, and a self-limiting risk group for females (5.4%, with the likelihood increasing with age, which peaked at the age of 21 years, and then declined. Likewise, six obesity risk groups (OG were detected, of which four corresponded to the first four high-risk WG groups. The risk groups were relatively independent of race and educational attainment.Conclusions: Findings of this study imply that five risk groups for weight gain like five consecutive "tests" exist from middle-school period to work-and-family formation. Failure to pass any of these tests in the life course could lead to overweight or obese status. Further research needs to study life

    These data demonstrate the magnitude of adolescent hookah use, particularly among adolescents who use electronic or traditional cigarettes. Most strikingly, rates of female adolescent use have increased much more rapidly than has male use, and adolescent females are for the first time more likely to smoke hookahs than adolescent males in the US nationwide. These findings urgently call for better understanding of the changing correlates of hookah use, including polytobacco use.

    To investigate the association between serum uric acid levels and insulin resistance in children and adolescents with obesity. Cross-sectional study with 245 children and adolescents (134 obese and 111 controls), aged 8 to 18 years. The anthropometric variables (weight, height and waist circumference), blood pressure and biochemical parameters were collected. The clinical characteristics of the groups were analyzed by t-test or chi-square test. To evaluate the association between uric acid levels and insulin resistance the Pearson's test and logistic regression were applied. The prevalence of insulin resistance was 26.9%. The anthropometric variables, systolic and diastolic blood pressure and biochemical variables were significantly higher in the obese group (p<0.001), except for the high-density-lipoprotein cholesterol. There was a positive and significant correlation between anthropometric variables and uric acid with HOMA-IR in the obese and in the control groups, which was higher in the obese group and in the total sample. The logistic regression model that included age, gender and obesity, showed an odds ratio of uric acid as a variable associated with insulin resistance of 1.91 (95%CI 1.40 to 2.62; p<-0.001). The increase in serum uric acid showed a positive statistical correlation with insulin resistance and it is associated with and increased risk of insulin resistance in obese children and adolescents.
