CI, confidence interval; OR, odds ratio; PA, physical activity; SB, sedentary behavior.
aHigh PA/Low SB was used as a reference group.
All estimates are from the conditional LGA model with covariate adjustment and distal outcome, and are weighted by a three cluster sampling design of 2013 national YRBS.
