Table 4. Associations of alcohol intake at baseline and job strain at follow-up, stratified by baseline job strain (n = 48 646)1.
| Population by baseline exposure | N participants | N (%) developing job strain | OR (95% CI)2 for job strain at follow-up |
| No job strain at baseline (N = 41 010) | |||
| Non-drinker | 5 503 | 713 (13.0) | 1.14 (1.04, 1.25) |
| Moderate drinker | 31 186 | 3 109 (10.0) | 1 (reference category) |
| Intermediate drinker | 1 731 | 143 (8.3) | 0.94 (0.79, 1.12) |
| Heavy drinker | 2 590 | 227 (8.8) | 0.97 (0.84, 1.12) |
| N (%) no job strain at follow-up | IRR (95% CI) 3 for no job strain at follow-up | ||
| Job strain at baseline (N = 7 636) | |||
| Non-drinker | 1 275 | 715 (56.1) | 0.97 (0.91 1.03) |

1
Studies and follow-up times: Belstress (4–8 years), FPS (2–4 years), HeSSup (5 years) and Whitehall II (3–9 years).
2
Odds ratios (ORs) from a mixed effects logistic model, adjusted for baseline age, sex and baseline socioeconomic position, with study as the random effect.
3
Incidence rate ratios (IRRs) from a modified Poisson model, adjusted for baseline age, sex and baseline socioeconomic position, with robust standard errors and study as the cluster variable.
