We evaluated officially reported adolescent HIB total incidents and estimated…

Background: The US Centers for Disease Control and Prevention (CDC) promotes school-based strategies to increase physical activity (PA). Implementation feasibility and effect of these interventions on cardiovascular fitness (CVF) is unknown. Methods: Forty-nine low-SES schools were randomly assigned to either (1) continue routine PA programs (N =…

Background: Embedded within children's weight trajectories are complex environmental contexts that influence obesity risk. As such, the normative environment of body mass index (BMI) within schools may influence children's weight trajectories as they age from kindergarten to fifth grade. Methods: I use 5 waves of the ECLS-K--Kindergarten Class…

Background: To improve school store food environments, the South Korean government implemented 2 policies restricting unhealthy food sales in school stores. A food-based policy enacted in 2007 restricts specific food sales (soft drinks); and a nutrient-based policy enacted in 2009 restricts energy-dense and nutrient-poor (EDNP) food sales. The…

Background: Authorities recommend that youth undertake at least 60 minutes of daily moderate-to-vigorous physical activity (MVPA), with young people having the opportunity to undertake at least half of this MVPA during school hours. Methods: In this study, we examined the influence of school-level socioeconomic status (SES) on children's PA,…

Background: A supportive school-based physical activity environment (PAE) is integral to children's physical activity behaviors, but less understood is its association with academic achievement.

A student's feeling of connectedness to school helps meet these challenges. Little is known, however, about the school characteristics that promote…

Background: Schools can be an efficient venue for promoting physical activity (PA) among adolescents. Physical education (PE) requires investigation because it is a variable associated with adolescent PA levels and its existence in schools represents a significant opportunity for strategies to combat declining PA levels among this population. This…

Background: To identify whether school health policies and programs vary by demographic characteristics of schools, using data from the School Health Policies and Programs Study (SHPPS) 2006.
