Likelihood of Having High Depressive Symptom Burden in Late Life According to Midlife PA Levels
| Midlife PA Group (n = 4,140) |
|||
|---|---|---|---|
| Inactive | Active | ||
| (n = 2,848) 174 with HDEPS |
(n = 1,292) 42 with HDEPS |
||
| Odds Ratio (95% CI: low, high) | |||
| Six or higher late-life depressive symptoms | Model 1 | Reference | 0.57 (0.41, 0.81) |
| Model 2 | Reference | 0.58 (0.41, 0.83) | |
| Model 3 | Reference | 0.57 (0.40, 0.82) | |
| Model 3 + MMSE | Reference | 0.58 (0.41, 0.83) | |
| Model 3 + SP | Reference | 0.61 (0.42, 0.86) | |
| Model 3 + MEM | Reference | 0.59 (0.41, 0.84) | |
| Model 3 + EF | Reference | 0.59 (0.41, 0.84) | |
| Model 3 + SP, MEM, and EF | Reference | 0.61 (0.43, 0.86) | |
Notes: CI = confidence interval, HDEPS = high depressive symptoms; PA = physical activity.
Model 1 = adjusted for age, sex, and education. Model 2 = Model 1 + Midlife risk factors: body mass index (BMI), systolic blood pressure, current smoking, cholesterol, coronary event, never smoked, and self-reported stroke. Model 3 = Model 2 + antidepressant medication use. Model 3 + MMSE = Model 3 adjusted for MMSE. Model 3 + SP = Model 3 adjusted for speed of processing (SP). Model 3 + MEM = Model 3 adjusted for memory (MEM). Model 3 + EF = Model 3 adjusted for executive function (EF). Model 3 + SP, MEM & EF = Model 3 adjusted for all cognitive function (SP, MEM, and EF).
