Factors Related to High-School Students' Odds of Having Overweight or Obesity.

This study used data the Youth Risk Behavior Surveillance System ( = 7,088) to examine factors associated with the odds of overweight/obesity. Overweight/obese was defined as a body mass index ≥85th percentile, based on age- and sex-specific growth charts. Participants were categorized into meeting/not meeting guidelines for: sleep, moderate-to-vigorous PA (MVPA), muscle strengthening PA, screen time, breakfast eating, fruit and vegetable consumption, and soda and milk consumption. Logistic regression analyses determined whether meeting guidelines for each health behavior was associated with the odds of students having overweight/obesity in the total group and stratified by sex. Meeting MVPA guidelines was the only behavior associated with having a lower odds of overweight/obesity in both sexes. For females, meeting recommendations for breakfast eating and strength training were also associated with lower odds of having overweight/obesity, whereas for boys, getting the recommended amount of sleep was associated with having lower odds of overweight/obesity. Interventions to reduce the prevalence of overweight/obesity in youth should be implemented inside and outside of the school environment and should include components addressing physical activity, diet, and sleep. Such interventions should address barriers to healthy behaviors that are unique to adolescents already affected by overweight/obesity.
