Note: 3MSE = Modified Mini-Mental State Examination; BMI = body mass index; CES-D = Center for Epidemiologic Studies-Depression; CVD = cardiovascular disease; DSST = digit symbol substitution test; TIA = transient ischemic attack.
*Spearman correlation coefficient for continuous variable and group mean difference (SD) from t-test for categorical variable.
†Knee pain (in the past month) was evaluated during the visit at Year 10.
‡For usual-paced walking speed, n = 269 participants.
