Note. PCS Physical component summary, MCS Mental component summary, SB sedentary behavior, LPA light-intensity physical activity, MVPA moderate- to vigorous-intensity physical activity
Regression coefficients correspond to a 10-min/day increment of each activity. Bold font denotes significant association
All models adjusted for age (years), gender, marital status (married/widowed, divorced, separated, or never married), highest educational attainment (up to and including high school/university, junior college, vocational school, or higher degree), the number of past illnesses, complications and comorbidity, and BMI (kg/m²). The single-activity and IS models also adjusted for total accelerometer wear time
