Unadjusted regression model.

Adjusted by age, sex, race, region of residence, and education.

Adjusted by age, sex, race, region of residence, education, proportion of time spent in sedentary behavior, body mass index, hypertension, smoking and diabetes.

Denotes the proportion of total time spent in moderate to vigorous physical activity.

Denotes the quartiles of the proportions of total time spent in moderate to vigorous physical activity. Q1 refers the lowest quartile, and Q4 refers the highest quartile.

The U.S. Physical Activity Guidelines recommended older adults perform ≥150 minutes of moderate to vigorous physical activity per week.²⁴
