Road traffic noise, noise sensitivity, noise annoyance, psychological and physical health and mortality

Abstract Background Both physical and psychological health outcomes have been associated with exposure to environmental noise. Noise sensitivity could the same moderating effect on related noise as annoyance but this has little tested. Methods A cohort of 2398 men between 45 59 years, longitudinal Caerphilly Collaborative Heart Disease study, was established in 1984/88 followed into mid-1990s. Road traffic maps were assessed at baseline. Psychological ill-health measured phase 2 1984/88, 3 (1989/93) 4 (1993/7). Ischaemic heart disease clinic baseline through hospital records deaths during follow up. We examined associations road ischaemic morbidity mortality using Cox Proportional Hazard Models Logistic Regression; we also whether might moderate these associations. tested if predictors ill-health. Results not or mortality. Neither nor moderated effects High lower risk (HR = 0.74, 95%CI 0.57, 0.97).
