  1. Sedentary behavior %: proportion of daily time (out of 100%) spent in sedentary behavior from accelerometer counts less than 100 per minute. LPA %: proportion of daily time (out of 100%) spent in light physical activity from accelerometer counts 100–1952 per minute. MPA %: determined by accelerometer counts greater than 1952 per minute, dichotomized into those achieving less than or greater than 3 min per day
  2. ERA Expectations regarding aging, LPA Light physical activity, MPA Moderate physical activity, ASMM Appendicular skeletal muscle mass, SPPB Short physical performance battery
