Background: School environments are important to consider for children's health. This study aims to determine if childhood peer bullying and school connectedness are associated with adolescent adiposity. Methods: A total of 3377 children from the age 9 child interview of the Fragile Families and Child Wellbeing Study had self-reported bullying and…

Background: Evidence for the effectiveness of state-mandated body mass index (BMI) screening programs in the United States has been inconclusive, and potential unintended consequences of the programs have been debated. The present review aims to understand parents' perceptions of and responses to school-based BMI screening, and to highlight…

Background: Childhood malnutrition is commonplace among poor rural communities in China. In 2012, China launched its first nationwide school-feeding program (SFP) to address this problem. This study examines the prevalence of malnutrition before and after the SFP and identifies possible reasons for the trends observed. Methods: Ordinary least…

Background: Moderate-to-vigorous physical activity (MVPA) declines during adolescence, particularly among girls. In this randomized control trial, we examined MVPA in a physical activity intervention compared to physical education (PE) class as usual (TAU), stratified by sex and weight classification. Standardized BMI (zBMI) overtime was also…

Background: This study aims to quantify associations between one's weight management goal and eating behaviors and physical activity among teenagers. Methods: Weighted logistic regressions were performed predicting healthy behaviors from weight goal separately for boys and girls while controlling for age, body mass index, socioeconomic indicators,…

BACKGROUND: Low-functional health literacy (HL) of parents influences poor child health outcomes. This study aimed to assess the relationship between comprehensive HL of parents and body mass index (BMI) of their children. METHODS: We enrolled 3- to 6-year-old preschool-aged children and their parents in this multicenter cross-sectional cohort…

Background: Physical activity at schools is an important component in combatting childhood obesity. Studies have shown that physical activity at school is positively associated with academic outcomes. The purpose of this study is to examine associations between opportunity of physical activity time at school and academic outcomes. Methods: This…

Background: Physical activity (PA) is one of the most important health behaviors that may be modified by each individual. To foster PA in adolescents, a school-based intervention was evaluated. Methods: A cluster-randomized controlled trial with preassessment in 2014 and follow-up assessment in 2015 included 29 schools with 1020 students (47.6%…

Background: The accuracy of students' heights and weights measured by school staff for body mass index (BMI) screening/reporting has not been established. This study examined school staffs' measurement accuracy, comparing accuracy by staff- and student-level characteristics. Methods: School staff and researchers measured the height and weight of…

Background: The school environment has the potential to influence student body mass index (BMI) through programs and policies. Our objective was to examine the effect of modifying obesity-related school policies and programs on youths' BMI trajectories. Methods: Obesity-related school policies and programs related to physical activity and healthy…

Background: Our objective was to examine the association between school wellness committees and implementation of nutrition wellness policies and children's weight status and obesity-related dietary outcomes. Methods: A cross-sectional study was conducted of 4790 children aged 4-15 years recruited from 130 communities in the Healthy Communities…

Background: Most pediatric elevated blood pressure (BP) remains undiagnosed. The American Academy of Pediatrics states "there is limited evidence to support school-based measurement of children's BP." We explored the utility school-based BP screening. Methods: A cross-sectional sample of 4096 students ages 6 to 17 from Title 1 Miami-Dade…

Background: Many studies document associations between low health literacy (HL) and poor health behaviors and outcomes. Yet, HL is understudied among adolescents, particularly from underserved, rural communities. We targeted rural adolescents in this cross-sectional study and explored relationships between HL and (1) energy-balance-related health…

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…

Background: Food-insecure (FIS) adolescents struggle in school and with health and mental health more often than food-secure (FS) adolescents. Rural communities experience important disparities in health, but little is known about rural FIS adolescents. This study aims to describe select characteristics of rural adolescents by food-security…
