  1. a activPAL measures: daily total sitting time, mean sitting bout duration, number daily sitting bouts > 30 min, number daily sit-to-stand transitions, daily total standing time, daily total steps
  2. b ActiGraph measures: daily total LPA, daily total MVPA
  3. c LPA and MVPA defined using Objective Physical Activity and Cardiovascular Health in older Women (OPACH) cutpoints, which are validated for an older adult population
  4. d The β parameter (with 95% CI) corresponds to the estimated change in the mean of the given sedentary behavior or physical activity measure associated with a 1-unit increase in CCIcurrent; model adjusted for age, sex, race/ethnicity, education, BMI, depressive symptoms, and device wear time
