Model 1, year adjusted; Model 2, adjusting year, demographics and selected risk behaviors; Model 3, adjusting year, demographics, selected risk behaviors and weight management

Reference group for each model: BMI Level 3 (18.5–24.9 kg/m²); Demographics covariates include age, sex, and race/ethnicity; selected risk behaviors included driving after alcohol consumption, suicide attempts, smoking status, current alcohol use, and sexual intercourse
