p-value is based on the cohort from GEE models adjusted for age (at baseline), education (at baseline, high school or less/some college, college graduate or more), race/ethnicity (non-Hispanic White, Other), site (Durham, Greensboro), marital status (time varying: married, not married), general health (time varying: excellent/very good, good, fair/poor), work status (time varying: employed full-time, employed part-time, not employed), and body mass index (time varying: continuous)
among those who worked at either baseline or follow-up.
among those who reported any sports or exercises at either baseline or follow-up.
GEE=generalized estimating equation; IQR=interquartile range; KPAS=Kaiser Physical Activity Survey; MET=metabolic equivalent
Note: The household/caregiving, occupational, sports, and active living indices ranged from 1 to 5, with the higher number indicating more physical activity from those modes.
