BACKGROUND AND PURPOSE: The main purpose of this study was to test whether the impact of job control on stroke mortality is independent of socioeconomic factors. METHODS: This was a register-based cohort study of nearly 3.5 million working people (25 to 64 years of age in the 1990 Swedish Census) with a 5-year follow-up for stroke mortality. Job control was aggregated to the data from a secondary data source (job exposure matrix). Gender-specific Poisson regressions were performed. RESULTS: Compared with high job control occupations, low job control was significantly related to hemorrhagic (relative risk, 1.54; 95% CI, 1.10 to 2.17) and all-stroke mortality (relative risk, 1.50; 95% CI, 1.11 to 2.03) in women but not in men. The significance of job control in women was independent of all confounders included (marital status, education level, and occupational class). Class-specific analyses indicated a consistent effect of job control for most classes (significant for female lower nonmanuals). However, low job control did not increase the risk of stroke mortality in upper nonmanuals. CONCLUSIONS: Job control was significantly related to hemorrhagic and all-stroke mortality in women but not in men.
