| Physical activity | Unadjusted OR (95% CI) | Adjusted |
|---|---|---|
| Low (n=38) | 1 (Reference) | 1 (Reference) |
| Moderate (n=38) | 0.53 (0.21−1.31) | 0.86 (0.28−2.65) |
| High (n=35) | 0.18 (0.06−0.51) | 0.25 (0.06−0.99) |
OR: odd ratio, CI: confidence interval.
Physical activity: low, ≤10.0 metabolic equivalents (METs)-hr/wk moderate, 10.1−23.9 METs-hr/wk high, ≥24.0 METs-hr/wk.
