Key Points Question What are the associations and interactions of physical activity and screen time categories with body mass index and overweight and obesity among adolescents? Findings In this cross-sectional study of 5797 US adolescents aged 10 to 14 years, a combination of high screen time (hours per day) and low physical activity (step count per day) was associated with overweight and obesity. Meaning These findings suggest that high step count may not offset overweight and obesity risk for adolescents with high screen time and that low screen time may not offset overweight and obesity risk for adolescents with low step count.
