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 examined the sustainability of New Moves, a school-based program aimed at decreasing weight-related problems in adolescent girls. The National Cancer Institute recognizes New Moves as a research-tested intervention program that produced positive behavioral and psychosocial outcomes. Methods: Ten schools participated in the…

Background: This study aimed to assess whether a school-based physical education intervention was effective in improving physical abilities and influencing daily physical activity habits in primary school children. The possible effect on body mass index (BMI) was also considered. Methods: Twenty-six 3rd-grade classes were randomly selected…

Background: Children spend most of their awake time at school, and it is important to identify individual and school-level correlates of their physical activity (PA) levels. This study aimed to identify the between-school variability in Portuguese children PA and to investigate student and school PA correlates using multilevel modeling. Methods:…

Background: In 2009, the Pennsylvania Department of Health developed the Active Schools Program (ASP) which required 30?minutes of daily physical education (PE) in middle schools to reduce childhood obesity. This investigation evaluated the ASP effects on physical fitness and weight status in middle school adolescents throughout 1 academic year.…

Background: This study examined the association between fitness change and subsequent academic performance in Taiwanese schoolchildren from 7th grade to 9th grade. Methods: The 7th graders from 1 junior high school district participated in this study (N=669). Academic performance was extracted from school records at the end of each grade.…

Background: Detailed knowledge about physical activity energy expenditure (PAEE) can guide the development of school interventions aimed at reducing overweight in adolescents. However, relevant components of PAEE have never been objectively quantified in this population. This study investigated the contribution of active transport to and from…

Background: Relatively little is known about how perceived weight controllability influences important psychological health factors among adolescents. Thus, the purpose of this study is to explore adolescents' weight controllability beliefs and how those beliefs influence weight-related attitudes and behaviors. Methods: Adolescents (N = 369, mean…

Background: The purpose of the study was to assess adolescents' perceptions of controllability and its relation to weight stereotypes as a function of gender. Methods: Two hundred and thirty-one seventh and eighth graders from physical education classes completed a perception of controllability questionnaire and weight stereotype explicit scale…

Background: While the importance of individual and school factors as correlates of overall youth physical activity has been demonstrated by previous research, less is known about the relationship of these factors with specific patterns of physical activity during adolescence. Thus, the purpose of this study was to examine the association of…

Background: This study examined physical activity (PA) levels of overweight and nonoverweight African American and Caucasian students (n = 198) during game play in physical education classes. Methods: Body fat percentages (%BFs) were determined using the skinfold technique and Slaughter et al prediction equations. Girls were classified as…

Objectives: To determine relationships between physical fitness and academic achievement in diverse, urban public school children. Methods: This cross-sectional study used public school data from 2004 to 2005. Academic achievement was assessed as a passing score on Massachusetts Comprehensive Assessment System (MCAS) achievement tests in…

Background: The purpose of this study was to determine the relation between weight status and participation in physical activity (PA) among Hispanic and non-Hispanic white (NHW) adolescent boys and girls. Methods: In this cross-sectional study, height and weight were measured and a modified 2001 Youth Risk Behavior Survey was administered to 1302…

Investigated overweight adolescents' attitudes toward the development of school-based weight control programs, examining their level of interest in participating and noting outcomes they desired. Interviews with 61 adolescents indicated they were interested provided the programs were enjoyable, informative, caring, and supportive; did not conflict…

Data from the 1990 North Carolina Youth Risk Behavior Survey were used to examine adolescents' perceptions of relative weight and the relationship of these perceptions to physical activity levels, weight loss efforts, and television viewing time. About 25 percent (860) considered themselves too fat and reported little physical activity. (SM)
