Physical inactivity determinants of low back pain after one to four years (OR and 95% confidence intervals)
| Low back pain after one to four years* | |||
|---|---|---|---|
| % | One year period prevalence (41.2%) | Chronic low back pain (13.9%) | |
| *Separate logistic regression models for one period prevalence of LBP and chronic LBP and for the separate physical inactivity parameters. All logistic regression models included age, gender, LBP at baseline. The ORs for age, gender, and the LBP parameters came from the model including the first physical activity parameter (that is, <0.5 h per day work and leisure time activities). | |||
| Age (per 10 years) | 0.86 (0.80 to 0.92) | 1.11 (1.00 to 1.23) | |
| Gender (women (n=2066) v men (n=1693)) | 1.76 (1.53 to 2.04) | 2.00 (1.61 to 2.48) | |

| One year period prevalence | 53.7 | 5.74 (4.95 to 6.67) | – |
| Chronic (>3 months) | 19.3 | – | 8.65 (7.04 to 10.6) |
| Physical inactivity | |||
| <0.5 h per day, work and leisure time | 36.1 | 1.05 (0.90 to 1.22) | 0.97 (0.78 to 1.20) |
| <0.5 h per week, work and leisure time | 12.9 | 1.03 (0.83 to 1.28) | 0.85 (0.63 to 1.15) |
| <0.5 hour per day, leisure time | 51.8 | 1.04 (0.90 to 1.21) | 0.99 (0.80 to 1.21) |
| <0.5 hour per week, leisure time | 23.3 | 1.11 (0.94 to 1.32) | 0.91 (0.72 to 1.15) |
