Age adjusted odds ratios (95% confidence intervals) of joint pain, morning stiffness, obesity, and radiological osteoarthritis (ROA) for locomotor disability
| Men | Women | |||
|---|---|---|---|---|
| Pain | ||||
| Hip | 3.6 (2.3, 5.7) | 5.3 (4.0, 7.0) | ||
| Knee | 3.4 (2.3, 5.0) | 3.0 (2.3, 3.9) | ||
| Morning stiffness | 6.5 (3.6, 11.8) | 6.5 (4.4, 9.6) | ||
| Obesity* | 1.7 (1.1, 2.6) | 1.7 (1.3, 2.3) | ||
| Grade ⩾2 | Grade ⩾3 | Grade ⩾2 | Grade ⩾3 | |
| ROA | ||||
| Hip | 1.7 (1.2, 2.6) | 3.1 (1.4, 6.9) | 2.9 (2.2, 3.9) | 7.4 (4.4, 12.5) |
| Knee | 1.4 (0.9, 2.0) | 4.5 (2.1, 9.7) | 1.7 (1.4, 2.2) | 3.5 (2.1, 5.8) |
| ROA + pain | ||||
| Hip | 3.1 (1.4, 7.2) | 4.0 (1.0, 15.8) | 7.4 (4.4, 12.3) | 15.5 (6.4, 37.5) |
| Knee | 3.3 (1.8, 6.1) | 11.5 (3.7, 36.0) | 3.1 (2.2, 4.4) | 6.6 (3.1, 14.3) |
ROA = radiological osteoarthritis. *Obesity, body mass index fourth quartile versus second quartile (men: >27.8 versus 23.9–25.7, women: >29.2 versus 23.9–26.3).
