Road Traffic Noise and Incident Myocardial Infarction: A Prospective Cohort Study

Both road traffic noise and ambient air pollution have been associated with risk for ischemic heart disease, but only few inconsistent studies include both exposures.) and other potential confounders: age, sex, education, lifestyle confounders, railway and airport noise.) was significantly associated with MI, with an incidence rate ratio IRR of 1.12 per 10 dB for both of the two exposure windows: yearly exposure at the time of diagnosis (95% confidence interval (CI): 1.02–1.22) and 5-years time-weighted mean (95% CI: 1.02–1.23) preceding the diagnosis. Visualizing of the results using restricted cubic splines showed a linear dose-response relationship.Exposure to long-term residential road traffic noise was associated with a higher risk for MI, in a dose-dependent manner
