Neighborhood Environments and Socioeconomic Inequalities in Mental Well-Being.

Abstract

It has been suggested that socioeconomic inequalities in health might be reduced among populations with good access to green space. However, the potential for other neighborhood characteristics to reduce socioeconomic health inequalities, or to confound the effects of green space, has not been well explored. Therefore, this study investigates which, if any, neighborhood characteristics are associated with narrower socioeconomic inequalities in mental well-being in a large, international sample of urban residents. The 2012 European Quality of Life Survey provided data on 21,294 urban residents from 34 European nations. Associations between mental well-being (captured by the WHO-5 scale) and level of financial strain were assessed for interaction with five different neighborhood characteristics, including reported access to recreational/green areas, financial services, transport, and cultural facilities. Multilevel regression models allowed for clustering of individuals within region and country in this cross-sectional, observational study. Data were analyzed in 2014. Socioeconomic inequality in mental well-being was 40% (8.1 WHO-5 points) narrower among respondents reporting good access to green/recreational areas, compared with those with poorer access. None of the other neighborhood characteristics or services were associated with narrower inequality. If societies cannot, or will not, narrow socioeconomic inequality, research should explore the so-called equigenic environments-those that can disrupt the usual conversion of socioeconomic inequality to health inequality. This large, international, observational study suggests that access to recreational/green areas may offer such a disruption.
