  1. Statistically significant results are bolded
  2. Standardized β are interpreted as the difference in MCS or PCS pts. per 1 SD difference in: SB (short) SD = 88 min per day; 10-year change in SB (short) = 75 min per day; LPA SD = 85 min per day; 10-year change in LPA SD = 111 min per day; MVPA (short) SD = 13 min per day; 10-year change in MVPA (short) SD = 13 min per day; MVPA (long) SD = 18 min per day; 10-year change in MVPA (long) = 19 min per day
  3. *Model 1 includes all activity variables and also adjusts for baseline value of MCS or PCS, follow-up time, accelerometer wear time, age, race, gender, education, smoking, and center
  4. **Model 2 adds adjustment for baseline and 10-year change in BMI
  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
