Notes: aCrude model, no covariate was adjusted. bModel 1, age, sex, race were adjusted. cModel 2, age, sex, race, marital status, education, poverty status, body mass index, smokers, alcohol drinkers, hypertension, diabetes mellitus, and cardiovascular diseases were adjusted. CI, confidence interval; LPA, light-intensity physical activity; MVPA, moderate-to-vigorous physical activity.
