Association between skin conditions and depressive disorders in community-dwelling older adults

Depression is frequently observed in dermatologic patients. However, the association between depressive disorders and skin conditions has rarely been explored through population-based studies, especially within older-adult populations.

To test this association in a representative sample of an older-adult population.

Data came from the Survey on the Health of the Elderly (Enquête sur la Santé des Aìnés [ESA]), a longitudinal survey conducted in Quebec among 2,811 older adults. Cross-lagged panel models were used to simultaneously examine cross-sectional and longitudinal relationships between the presence of skin conditions and depressive disorders.

The prevalence of skin conditions was 13%, and the prevalence of depressive disorders among participants presenting with skin conditions was 11%. Our results indicated significant cross-sectional correlation (ζ  =  0.20) between skin conditions and depressive disorders, but no longitudinal association was observed.

Our results reinforce the hypothesis that skin conditions and depressive disorders are concurrently associated in older adults. However, no evidence of the predictive effect of skin problems on depression (and vice versa) was found in our community sample. Despite the deleterious effect of the coexistence of these problems in older adults, studies are lacking. This article highlights the importance of this issue and emphasizes the need for further research on this topic.
