Engagement in Sedentary and Physically Active After-School Programs Among African American Children with ADHD and Disruptive Behavior Disorders.

Context: Sport and physical activity (PA) programs are an important developmental resource for youth with Attention Deficit Hyperactivity Disorder (ADHD) and Disruptive Behavior Disorders. The purpose of this study is to assess sport participation rates, PA participation, and after-school supervision rates among African American children with ADHD and/or Disruptive Behavior Disorders.

Design: In this cross-sectional study, parents of African American children with elevated symptoms of ADHD, oppositional defiant disorder, and/or conduct disorder (N = 175, 6- to 12-y-old, 31% female) reported after-school program participation over the past year.

Sociodemographic disparities in sedentary time among US youth vary by period of the day.

Introduction: Studies have reported sex and race/ethnicity disparities in sedentary time (ST), but none have evaluated ST by well-defined periods of the weekday (before school, during school, afterschool, and evening) and weekend day (morning, afternoon, and evening). Comparing sex and race/ethnicity disparities in ST at different periods of a weekday and weekend day can deepen our understanding of disparities and inform intervention efforts. This study tests sex and race/ethnicity disparities in ST by period of day in a representative sample of US youth.

The convergent effects of primary school physical activity, sleep, and recreational screen time on cognition and academic performance in grade 9.

Lab-based experiments and randomized controlled trials consistently demonstrate improvements in youth cognition following physical activity (PA), while cross-sectional studies suggest that sedentary behavior (especially recreational screen time [RST]) and poor sleep are inversely related to cognition. However, little is known about how these 24-h movement behaviors-sleep, PA, and sedentary behavior-converge to affect youth cognition. Therefore, the purpose of this study is to test the associations between childhood 24-h movement behaviors and adolescent cognition using a longitudinal design and examine moderating effects of each behavior.

Developmental disparities in sedentary time by period of the day among US youth: a cross-sectional study.

Background: Definitive evidence shows sedentary time (ST) is an independent risk factor for chronic disease, irrespective of physical activity. Despite calls to limit youth ST, studies demonstrate a spike in ST at the transition from childhood to adolescence. Identifying periods of the day (e.

Protocol for a multicenter-cluster randomized clinical trial of a motor skills intervention to promote physical activity and health in children: the CHAMP afterschool program study.

Background: Promoting health-enhancing and sustainable physical activity levels across childhood and adolescence contribute to positive health outcomes as an adult. This study will aim to: a) examine the immediate (pre- to post-intervention) and sustained (1-year post-intervention follow-up) effects of the Children's Health Activity Motor Program-Afterschool Program (CHAMP-ASP) on physical activity, motor competence, and perceived motor competence relative to the comparison ASP, b) examine the immediate and sustained effects of CHAMP-ASP on secondary health outcomes, specifically health-related physical fitness (i.e.

Device-Based Movement Behaviors, Executive Function, and Academic Skills among African American Children with ADHD and Disruptive Behavior Disorders.

Background: Physical activity (PA) has been identified as a promising intervention to improve executive function (EF) and reduce ADHD symptoms in children. Few African American children with ADHD and Disruptive Behavior Disorders (DBDs) from families with low incomes are represented in this literature. The purpose of this study is to test the relationships between PA and sedentary time (ST), and EF and academic skills among African American children with ADHD and DBD from low-income families.

The S.P.A.C.E Hypothesis: Physical Activity as Medium - Not Medicine - for Public Health Impact.

Most scientifically tested physical activity interventions end when research funding ends; interventions that last struggle to sustain benefits. We hypothesize that long-term public health impact will benefit from a shift in how interventionists conceptualize physical activity - from a form of medicine, of value for its innate health benefits, to a malleable medium, of value for the dynamic contexts it creates.
