[BDSP. Notice produite par INIST-CNRS 8R0xA8BH. Diffusion soumise à autorisation]. Objectives. We examined whether the distinctive components of job control-decision authority, skill discretion, and predictability-were related to subsequent acute myocardial infarction (Ml) events in a large population of initially heart disease-free industrial employees. Methods. We prospectively examined the relation between the components of job control and acute Ml among private-sector industrial employees. During an 18-year follow-up, 56 fatal and 316 nonfatal events of acute Ml were documented among 7663 employees with no recorded history of cardiovascular disease at baseline (i.e., 1986). Results. After adjustment for demographics, psychological distress, prevalent medical conditions, lifestyle risk factors, and socioeconomic characteristics, low decision autonomy (P<. 53) and skill discretion (P<. 10) were not significantly related to subsequent acute Ml. By contrast, low predictability at work was associated with elevated risk of acute Ml (P=02). This association was driven by the strong effect of predictability on acute Ml among employees aged 45 to 54 years. Conclusions. Prospective evidence suggests that low predictability at work is an important component of job control, increasing long-term risk of acute Ml among middle-aged employees.
