Styrene and ischemic heart disease mortality among synthetic rubber industry workers

Academic Article


  • Objective: We examined the relation between styrene and ischemic heart disease (IHD) mortality among 16,579 men in the synthetic rubber industry. Methods: Associations were measured using stratified and multivariable analysis. Results: Compared with workers with no exposure to styrene, men in the highest quintile of average intensity of exposure (5.50+ parts per million [ppm]) and in the highest quintile of cumulative exposure (60.67+ ppm-years) had, IHD rate ratios of 1.14 (95% confidence internal [CI] = 0.96-1.35) and 1.07 (95% CI = 0.90-1.27), respectively. Acute IHD was not associated with average intensity of exposure within the most recent 2 years or with other indices of exposure. Chronic IHD rates were elevated in subjects with the highest exposure; these associations were weak and imprecise, and evidence of a positive exposure-response relation was limited. Conclusion: This study does not indicate that exposure to styrene causes fatal IHD. Copyright © by American College of Occupational and Environmental Medicine.
