This study shows that road traffic noise >60 dB (compared to <45 dB) was associated with poor self-rated health in men, but not in women. This association was stronger among men with high trait anxiety scores. Noise levels were not associated with psychotropic medication use.

Associations of traffic noise with self-rated health and psychotropic medication use. Scand J Work Environ Health. 2014;40(3):235-243. doi:10.5271/sjweh.3408 Objectives Road traffic noise is a common environmental nuisance, which has been thought to increase the risk of many types of health problems. However, population-level evidence often remains scarce. This study examined whether road traffic noise is associated with self-rated health and use of psychotropic medication in a cohort of public sector employees.Methods Data are from the Finnish Public Sector Study cohort. Geographical information system (GIS) was used to link modeled outdoor road traffic noise levels (L den ) to residential addresses of 15 611 men and women with cross-sectional survey responses on self-rated health and register-based information on the use of antidepressants, anxiolytics, and hypnotics. High trait anxiety scores were used to identify potentially vulnerable individuals. The analyses were run with logistic regression models adjusting for individual and area-level variables. All participants were blind to the aim of the study.
ResultsMean level of road traffic noise at participants' home addresses was 52 decibels (dB) (standard deviation 8.1). Noise level >60 dB versus ≤45 dB was associated with poor self-rated health in men [odds ratio (OR) 1.58, 95% confidence interval (95% CI) 1.14-2.21]. Further stratification revealed that the association was evident only among men with high trait anxiety scores (OR 2.23, 95% CI 1.28-3.89). No association was found with psychotropic medication use or among women.
ConclusionExposure to road traffic noise was not associated with increased use of psychotropic medication, although it was associated with weakened self-rated health among men.Key terms antidepressant; anxiety; cohort study; environmental noise; road traffic; trait anxiety; vulnerable. With ever increasing traffic volumes and urbanization, road traffic noise is already one of the most common environmental nuisances globally. The World Health Organization (WHO) recommends noise levels of <50 decibels (dB) and <40 dB at day-and night-time, respectively, to limit public disturbance (1, 2). More recently, to identify populations exposed to high noise levels, the European Commission required environmental noise maps for urban areas with populations of >100...
