The sex-specific role of plasma folate in mediating the association of dietary quality with depressive symptoms.

ABSTRACT: Folate deficiency has been implicated in the etiology of unipolar depression. In this study, we attempted to cross-link plasma folate, depressive symptoms, and dietary quality (or dietary intake of folate) together in a comprehensive framework, while examining effect modification of those associations by sex.
