Combinations of different risk factors for neck pain among male and female computer users, stratified for sex and adjusted for age
| Risk factor | Men and women | ||
|---|---|---|---|
| HR (95% CI) | Events/censored | Excess risk | |
| Note that only respondents with low exposure for both risk factors and high exposure for one or both risk factors were included, all other possible exposure combinations being excluded. | |||
| HR, hazard ratio. | |||
| *Adjusted for physical exposure and age. | |||
| †Adjusted for job strain and age. | |||
| ‡Adjusted for perceived muscular tension and age. | |||
| Perceived muscular tension and job strain* | |||
| Low tension, low strain | 1 | 7/56 | |
| High tension, low strain | 3.3 (1.1 to 9.5) | 8/18 | |
| Low tension, high strain | 2.5 (0.90 to 6.8) | 9/23 | |
| High tension, high strain | 4.0 (1.6 to 10.0) | 19/28 | −0.19 |
| Perceived muscular tension and physical exposure† | |||
| Low tension, low physical | 1 | 20/90 | |
| High tension, low physical | 1.7 (0.92 to 3.3) | 23/52 | |
| Low tension, high physical | 0.83 (0.27 to 2.6) | 4/17 | |
| High tension, high physical | 1.9 (0.86 to 4.2) | 12/18 | 0.17 |
| Job strain and physical exposure‡ | |||
| Low strain, low physical | 1 | 17/89 | |
| High strain, low physical | 1.1 (0.51 to 2.5) | 14/49 | |
| Low strain, high physical | 0.54 (0.12 to 2.4) | 2/15 | |
| High strain, high physical | 2.7 (1.2 to 5.9) | 15/17 | 0.75 |
