Using the 2017-2018 National Health and Nutrition Examination Survey (weighted population size = 35,460,209; 8-18 years old; 52.1% males), we compared the obesity prevalence in children and adolescents between body mass index-based (BMI-based) and total percent body fat-based (BF%-based, measured by the dual-energy x-ray absorptiometry) cutoffs.…

Objective: To identify the lifetime prevalence and correlates of appearance- and performance-enhancing drugs and substances (APEDS) use among a national sample of US college and university students. Participants: Student participants from the 2020-2021 Healthy Minds Study (N = 7,401; ages 18-30 years). Methods: Lifetime prevalence of five forms of…

Youth with Autism Spectrum Disorder (ASD) are at an increased risk for developing obesity when compared to their typically developing peers. Given higher prevalence of obesity in youth with ASD, understanding factors relating to success in obesity treatment provides insight into implementing efficacious treatments for youth. The current study…

Children and adolescents with disabilities benefit from physical activity. However, this population has lower fitness levels and higher rates of obesity than their peers, suggesting that they are not meeting physical activity guidelines and are experiencing barriers to participation. The purpose of this study was to quantify physical activity…

The aims of the current study were to provide the first Australian prevalence estimates of sexual harassment in adolescents, explore gender differences in form and frequency of harassment, and investigate demographic and weight status correlates. A total of 4098 adolescents (47.3% boys), aged 11 to 19 years from government and non-government…

The purpose of this study was to examine current overweight and obesity prevalence rates among US youth (aged 10-17 years) with and without autism spectrum disorder, based on the 2016 National Survey of Children's Health. Analyses of weight status, derived from parent-reported height and weight measures, were conducted for a weighted sample of…

This dissertation addresses several contemporary health challenges affecting the US population, drawing on methods and perspectives from health services research, social demography, and medical sociology. Paper 1 examines the pathways from educational attainment to difficulty with activities of daily living (ADLs) and instrumental activities of…

Guided by the biopsychosocial model, we examined (a) the prevalence of weight control behaviors (WCBs; i.e., trying to stay the same weight, lose weight, gain weight, or do nothing about weight) among early adolescent boys by race/ethnicity and grade level, and (b) how the boys' perceptions of sociocultural pressures (from parents, peers, and…

Background: We examined the body mass index (BMI) of students attending Seventh-day Adventist (Adventist) schools in Australia in 2001 and 2012. Methods: A total of 3069 students attending Adventist schools in Australia responded to a health and lifestyle survey in 2001 (N = 1335) and 2012 (N = 1734). The survey captured self-reported height and…

Energy balance-related behavior on schooldays and beliefs about school-based interventions may differ between students in different educational levels, sexes, and BMI (body mass index) categories. In Zwolle (the Netherlands), 1,084 adolescents (13-15 years) at 9 secondary schools completed a questionnaire. Overweight prevalence (boys 18.1%, girls…

Objective: We examine weight control behavior used to (a) compensate for caloric content of heavy alcohol use; and (b) enhance the psychoactive effects of alcohol among college students. We evaluate the role of gender orientation and sex. Participants: Participants completed an online survey (N = 651; 59.9% women; 40.1% men). Method: Weight…

This study examines the prevalence of overweight and obesity and a panel of potential determinants among French youths and adults with an intellectual disability (ID). The sample used consisted of 1120 youths and adults with an ID, from 5 to 28 years old, attending a French special education school. The results indicated that 19.8% of the…

Objective: Obesity and its comorbidities have emerged as a leading public health concern. The aim of this study was to explore the relationship between body mass index (BMI) and sleep patterns, including duration and disturbances. Methods: A convenience sample of 515 college students completed an online survey consisting of the Pittsburgh Sleep…

Background: The high rates of childhood overweight and obesity in the United States have generated interest in schools as sites for monitoring body mass index (BMI) information. This study established baseline values for a 5-year longitudinal assessment of BMI of elementary school children and examined variation across the schools, because little…

The purpose of this study was to describe the BMI status of children and youth with intellectual disabilities by world region, gender and age. A total of 9678 children and youth records were available from the Special Olympics International Health Promotion database after data cleaning (6084 boys and 3594 girls). Children were defined as 8-11 year…
