Table 2.

Association of slow gait speed with depressive symptoms trajectory groups with CES-D < 16 at baseline. Unadjusted and Adjusted^* Odds Ratio (OR) and 95% Confidence Interval (CI). Gait speed was categorized as >1.2 m/s, healthy gait speed; < 1.2 m/s, slow gait speed.

Mild depressive symptoms (n=1172)	22.0	1.6 [1.2, 2.0]	1.3 [1.0, 1.7]
