Mental health and the built environment: Cross – sectional survey of individual and contextual risk factors for depression

Abstract

BackgroundLittle is known about the effects of the physical environment on individual health.AimsThe present study tested the hypothesis that the prevalence of depression is associated with independently rated measures of the built environment, after adjusting for individuals' socio-economic status and the internal characteristics of their dwellings.MethodCross-sectional survey of 1887 individuals aged 16 years and over in two electoral wards in north London. Depression was ascertained using the Center for Epidemiologic Studies Depression scale (CES–D). The built environment was rated independently, using a validated measure.ResultsAfter adjusting for socio-economic status, floor of residence and structural housing problems, statistically significant associations were found between the prevalence of depression and living in housing areas characterised by properties with predominantly deck access (odds ratio=1.28, 95% Cl 1.03–1.58; P=0.02) and of recent (post-1969) construction (odds ratio=l.43, 95% Cl 1.06–1.91; P=0.02).ConclusionsThe prevalence of depression was associated with independently rated features of the built environment, independent of individuals' socio-economic status and internal characteristics of dwellings.
