Linear regression model was used to calculate coefficient: Model 1 was adjusted for age and accelerometer wear time. Model 2 was adjusted for the same covariates used in model 1 plus body mass index, smoking status, alcohol drinking, total energy intake, sodium intake, fat intake, educational background, hypertension, diabetes, and dyslipidemia. Model 3 was adjusted for the same covariates used in model 2 plus moderate-to-vigorous physical activity (when sedentary behaviour and light activity were examined) or sedentary (when moderate-to-vigorous physical activity was examined)
