^aModel 1 adjusted for field center, accelerometer wear time, age, and sex.

^bModel 2 additionally adjusted for income, education, employment status, body mass index, and comorbid conditions.

^cModel 3 additionally adjusted for objectively measured physical activity.

^dParticipants with missing values for any covariates were excluded from all models.

^eDependent variable: objectively measured time spent in sedentary behavior (< 100 counts/min), expressed in minutes per day.
