  1. High CRS refers to the highest quartile of CRS. Model 1: adjusted for age, gender, race, SES, smoking, total fat, saturated fat, cholesterol, and sodium. Model 2: Adjusted for covariates in Model 1 and MVPA. For the breaks in sedentary behavior variable, Model 1 and 2 were also adjusted for the volume of sedentary behavior. *P ≤ 0.05.
