What Did the Study Do?
Using the 2011 national Youth Risk Behavior Surveillance System (YRBSS) dataset (n = 15,503 highschool students), the authors examined how three behaviours—days of moderatetovigorous physical activity (PA), television viewing, and videogame/computer use—along with gender and Latina/o ethnicity, relate to Body Mass Index (BMI) categories. Logistic regression tested both main effects and whether the PA–weight link differed by ethnicity.
