*Multivariate analyses are adjusted for age, sex, education, ethnicity, smoking, light physical activity, alcohol consumption, history of diabetes, history of cardiovascular disease (coronary heart disease, congestive heart failure, stroke), history of cancer, and mobility limitations.
MVPA = moderate to vigorous physical activity; BMI = body mass index; sedentary time and moderate to vigorous physical activity were mutually adjusted.
