Note: Af Am = African American; HRQOL = health-related quality of life (higher indicates more impairment); min = minute; total PA = light-, moderate-, and vigorous-intensity physical activity. Due to skewed distribution, a square root transformation was used for depressive symptoms, HRQOL, and total PA. *indicates .
