Note. * p < .05, **p < .01, ***p < .001. SB = sedentary behavior, LIPA = light-intensity physical activity, MVPA = moderate- to vigorous-intensity physical activity. Regression coefficients correspond to a 10-min increment of each activity
Adjusted for age (years), sex, BMI (kg/m2), the number of past illnesses, complications and comorbidity, smoking status (current smoker/never smoked, past smoker), drinking status (current drinker/non-drinker, past drinker), residence status (living alone/living with someone), and highest educational attainment (up to and including high school / university, junior college, vocational school, or higher degree)
