BACKGROUND: Zonulin is acknowledged as the only physiological mediator established to reversibly regulate intestinal permeability through modulation of intercellular tight junctions. We aimed to determine whether there are differences in zonulin levels between 74 subjects with overweight or obesity and 76 with normal-weight and to assess correlations of circulating zonulin levels with anthropometric measures and obesity-related biomarkers. METHODS: We assessed anthropometric and laboratory measures, including body mass indes (BMI) z-score, blood pressure, liver enzymes, lipid profiles, and insulin resistance...

BACKGROUND: Obesity is associated with increased lifelong morbidity and reduced life span and is increasingly prevalent in the congenital heart disease population. Habitual exercise is an important aspect of a healthy lifestyle and primary prevention of obesity in the general population. The association between habitual activity and body mass index (BMI) has not been studied in children with congenital heart disease. METHODS: A cross-sectional analysis of two previously collected cohorts was performed, including participants 8 to 18 years old with tetralogy of Fallot, transposition of the great arteries, and single ventricle heart disease after a Fontan operation...

BACKGROUND: The prevalence of childhood obesity has significantly increased in Korea. This study aimed to use data from the 2010 Korea National Health and Nutrition Examination Survey (KNHANES) to investigate the association between sodium (Na) intake and insulin resistance in children and adolescents with obesity. METHODS: The study population consisted of 578 adolescents aged 12-18 years who were enrolled in the 2010 KNHANES. Subjects were classified into the following four groups based on their body mass index (BMI) and homeostatic model assessment-insulin resistance (HOMA-IR) values: normal BMI and HOMA-IR (Group 1), normal BMI and ≥75% HOMA-IR (Group 2), ≥85% BMI and normal HOMA-IR (Group 3) and ≥85% BMI and ≥75% HOMA-IR (Group 4)...

BACKGROUND: Oral glucose tolerance test (OGTT) is a traditional diagnostic tool for diabetes. Hemoglobin A1c (HbA1c) is an alternative method used in adults; however, its application in youths has been controversial. We evaluated the diagnostic performance of HbA1c and determined optimal cutoff points for detecting prediabetes and diabetes in youth. METHODS: This retrospective study included 389 obese children (217 boys, 55.8%) who had undergone simultaneous OGTT and HbA1c testing at six hospitals, Korea, between 2010 and 2016...

OBJECTIVE: Fat talk, negative communication about weight, is common in the media, peer groups, and families. Little is known about parental fat talk directed at oneself or others. This study examined associations between different forms of parental fat talk and child disordered eating behaviors and weight, and differences by child sex and age. METHOD: Parents of preadolescents or adolescents (n = 581) reported fat talk about themselves (self-fat talk), others (obesity-fat talk), and their child (child-fat talk)...

PURPOSE: Peer crowds are macro-level subcultures that share similarities across geographic areas. Over the past decade, dozens of studies have explored the association between adolescent peer crowds and risk behaviors, and how they can inform public health efforts. However, despite the interest, researchers have not yet reported on crowd size and risk levels from a representative sample, making it difficult for practitioners to apply peer crowd science to interventions. The current study reports findings from the first statewide representative sample of adolescent peer crowd identification and health behaviors...

The study aims to describe body phenotypes estimated by multivariate technique for the assessment of nutritional status in adolescence during the process of sexual maturation. The sample consisted of 833 schoolchildren 10 to 15 years of age, selected by complex sampling in Piracicaba, São Paulo State, Brazil. Body phenotypes were defined by principal components analysis (PCA) based on anthropometric data (body mass, height, skinfolds, and waist circumference), body composition (phase angle measurement by bioelectric impedance), biochemical parameters (triglycerides, glucose, total/LDL cholesterol ratio, hemoglobin), and sexual maturation (self-classification of stages of pubic hair and breasts or genitals)...

In adults, greater social integration is associated with reduced risk of cardiovascular disease, including hypertension. Social integration earlier in life may be similarly associated with cardiovascular risk. Using a longitudinal sample of 267 Black and White men, we examined whether greater social integration with peers during childhood and adolescence, assessed by parent report, prospectively predicts lower blood pressure and body mass index two decades later in adulthood and whether these effects differ by race, given well-documented racial disparities in hypertension...

Importance: Because of the substantial increase in the occurrence of type 2 diabetes in the pediatric population and the medical complications of this condition, therapies are urgently needed that will achieve better glycemic control than standard medical management. Objective: To compare glycemic control in cohorts of severely obese adolescents with type 2 diabetes undergoing medical and surgical interventions. Design, Setting, and Participants: A secondary analysis of data collected by the Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) and Treatment Options of Type 2 Diabetes in Adolescents and Youth (TODAY) consortia was performed...

Although bi-directional relationships between high body mass index (BMI) and affective symptoms have been found, no study has investigated the relationships across the life course. There has also been little exploration of whether the fat mass and obesity-associated (FTO) rs9939609 single-nucleotide polymorphism (SNP) is associated with affective symptoms and/or modifies the relationship between BMI and affective symptoms. In the MRC National Survey of Health and Development (NSHD), 4556 participants had at least one measure of BMI and affective symptoms between ages 11 and 60-64 years...

Although capsaicin has been reported to reduce energy intake and increase energy expenditure in an adult (normal weight or overweight) population, thus resulting in a net negative energy balance and weight loss, these beneficial effects have not been investigated in young obese subjects. We hypothesize that capsaicin acutely administered in young obese subjects exerts the same effects on energy balance and that these effects are mediated by changes in gastrointestinal peptides regulating appetite. Thus, the aim of the present study was to evaluate the acute effects of capsaicin (2 mg) or placebo on energy intake, hunger, and satiety in obese adolescents and young adults (female-male ratio: 4:6, age: 21...

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...

PURPOSE: Weight loss treatments targeting adolescents often occur in mixed-sex contexts and produce variable outcomes. Sex considerations may be of particular importance, especially given differences in social relating. This study aggregated data from two randomized controlled trials of a peer-enhanced intervention compared with a standard cognitive-behavioral weight loss intervention to test the hypothesis that adolescent girls may demonstrate greater benefit than boys from a peer-enhanced weight loss intervention...

OBJECTIVES: Despite evidence that American Indian adolescents are at a heightened risk of obesity/overweightness and experiencing depression, relative to other groups, there exists a dearth of studies that have examined the association between objective and perceptual measures of obesity and overweightness and depression with this understudied group. Our study represents one of the first studies to examine this association among American Indian youth. METHODS: Using a subsample of American Indian youth from waves I and II of the National Longitudinal Study of Adolescent Health (a survey of schools and students in the USA, with wave I collected in 1994 and wave II collected in 1995), we explore this association...

BACKGROUND: Existing evidence on the role of sociodemographic variables as risk factors for overweight and obesity in school-aged children is inconsistent. Furthermore, findings seem to be influenced by the obesity definition applied. Therefore, this study aimed to investigate if school sociodemographic indicators were associated with weight status in Irish primary schoolchildren and whether this association was sensitive to different obesity classification systems. METHODS: A nationally representative cross-sectional sample of 7542 Irish children (53...

BACKGROUND: Obesity has been hypothesized to be associated with reduced moderate-to-vigorous physical activity (MVPA) and increased sedentary time (ST). It is important to assess whether, and the extent to which, levels of MVPA and ST are suboptimal among children and adolescents with obesity. The primary objective of this study was to examine accelerometer-measured time spent in MVPA and ST of children and adolescents with obesity, compared with MVPA recommendations, and with non-obese peers...
