  1. Statistically significant results are bolded
  2. Model 1 is adjusted for baseline value of the activity variable, follow-up time, average accelerometer wear time, age, race, gender, education, smoking, and center
  3. Model 2 adds adjustment for baseline and 10-year change in BMI
  4. MCS SD = 8.83 points; MCS 10-year change SD = 9.07 points; PCS SD = 7.00 points; PCS 10-year change SD = 7.30 point
  5. Abbreviations: BMI body mass index, cpm counts per minute, LPA light-intensity physical activity, MCS mental component score, MVPA moderate-to-vigorous intensity physical activity, PCS physical component score, pts. points, ref. reference category, SB stationary behavior
