Noise nuisance and health inequalities in Belgium: a population study

Abstract Context Lower socioeconomic groups are more likely to live in contaminated environments. This may partly explain socioeconomic health inequalities. Aims Does noise nuisance contribute to socio-economic inequalities in subjective health? Method This research is based on the last Belgian census data carried out in 2001. We work on a 10% sample of the Belgian population. The data are processed through bivariate and multivariate analyses. We model poor subjective health in relation to exposure to noise nuisance and several socio-economic variables. Results The risk of poor subjective health increases with noise nuisance and is higher in lower socioeconomic groups. Noise nuisance does contribute to health inequalities, particularly regarding type of housing and activity. These relations are stronger in urban areas. Conclusions Noise nuisance affects the subjective health status and contributes to health inequalities, particularly in urban areas. This suggests that public policies, particularly those related to environmental planning, should be driven also by environmental equity considerations.
