| Physical activity | MET-min/week | Colorectal cancer | |
|---|---|---|---|
| BMI (Kg/m2) | |||
| Low BMI (N=1289) | High BMI (N=1617) | ||

| Low | <600 MET | 1 | 1 |
| Moderate | 600–3000 MET | 0.76 (0.62-0.92) | 0.83(0.71-0.97) |
| High | ≥3000 MET | 0.64 (0.50-0.92) | 0.78(0.64-0.95) |

¥Adjusted Odds Ratio (ORa); Multivariable model: conditional logistic regression using age in years, residence (urban, rural), education level (illiterate, primary, secondary, higher), monthly income (low, medium, high), smoking status (never smoker, Ex-smoker and current smoker), Non-steroidal anti-inflammatory drugs (yes or no), total energy intake (continuous), intakes of red processed meat and dietary fiber (both continuous), calcium (continuous), family history of colorectal cancer(yes or no).
