Stigmatization of overweight and obese individuals is common in interpersonal relationships. This study investigated longitudinal weight change patterns among Taiwanese adolescents and the relationship of weight change patterns with delayed romantic experience from late adolescence to young adulthood by using a representative panel survey.…

Sport Education is a curriculum model designed to provide all students with authentic sport experiences, regardless of their individual characteristics. Research showing the effectiveness of the model in promoting physical activity (PA) levels is still scant. In addition, interventions have mostly included invasion games as the main content, thus…

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…

Purpose: Physical education (PE) is an important context for promoting health-related cardiorespiratory fitness (CRF) in youth. Within PE, the lesson context and teacher behavior may be relevant for the promotion CRF; however, evidence is scarce. Therefore, the purpose of this study was to assess whether students' CRF improvement in a school year…

Although there is a growing consensus about the positive relationship between prevention of overweight/obesity and academic performance in children, relevant studies targeting the relationship between underweight and academic performance are scarce. This study aimed to examine the longitudinal relationship of favorable weight change to academic…

This research was conducted to determine whether there are differences between the norm values used in the evaluation of children who train in different sports and physical education lessons according to the chronological age and biological age of the children. The research group consists of a total of 239 male students of 13 (n=116) and 14…

Obesity rates among children and young adults are considered one of the most consequential global public health challenges of the 21st century (Hurt et al., 2010; WHO, 2016). Obesity comorbidities include propensity of low self-esteem (Franklin et al, 2006). Using the Theory of Planned Behavior (TPB), a triangulation mixed-methods,…

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…

The current study was designed to examine one possible weight stigma-reduction mechanism: school-level weight diversity. It was hypothesized that greater weight diversity among same-sex peers at school would attenuate the negative association between weight and academic achievement. Across 26 urban public middle schools, 5,991 sixth-grade students…

This study evaluated feasibility, acceptability, and preliminary efficacy of a 12-week "Guys/Girls Opt for Activities for Life" (GOAL) intervention on 10- to 13-year-old adolescents' body mass index (BMI), percent body fat, physical activity (PA), diet quality, and psychosocial perceptions related to PA and healthy eating.…

The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined…

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…

This study was planned in order to analyze adolescent body image by age and gender, evaluate the relationship between adolescent body image and socio-cultural factors, and determine the extent to which variables such as age, gender, and Body Mass Index (BMI) can serve as predictors of the influential habits and strategies needed to achieve a…

Background: It is known that suburban youth are more fit than urban youth in Croatia. Method: Differences (p < 0.05) in fitness levels and motor abilities of 9,164 (F = 4,671, M = 4,493) Croatian children (age range: 11-14 years) from urban (F = 1,380, M = 1,268), mixed rural-urban (F = 274, M = 289), and rural (F = 3017, M = 2936) areas were…
