Environmental and individual characteristics associated with depressive disorders and mental health care use

Abstract

PurposeFew studies examined the relationship between neighborhood characteristics and both depressive disorders and the corresponding mental health care use. The aim of our study was to investigate neighborhood effects on depressive symptomatology, antidepressant consumption, and the consultation of psychiatrists. MethodsData from the French Residential Environment and Coronary heart Disease Study (n = 7290, 2007–2008, 30–79 years of age) were analyzed. Depressive symptomatology was cross-sectionally assessed. Health care reimbursement data allowed us to assess antidepressant consumption and psychiatric consultation prospectively more than 18 months. Multilevel logistic regression models were estimated. ResultsThe risk of depressive symptoms increased with decreasing personal educational level and unemployment and slightly with decreasing neighborhood income. In a sample comprising participants with and without depressive symptoms, high individual and parental educational levels were both associated with the consultation of psychiatrists. In this sample, a low personal educational level increased the odds of consumption of antidepressants. No heterogeneity between neighborhoods was found for antidepressant consumption. However, the odds of consulting psychiatrists increased with median neighborhood income and with the density of psychiatrists, after adjustment for individual characteristics. Among depressive participants only, a particularly strong gradient in the consultation of psychiatrists was documented according to individual socioeconomic status. ConclusionsFuture research on the relationships between the environments and depression should take into account health care use related to depression and consider the spatial accessibility to mental health services among other environmental factors.
