Associations between the Dietary Inflammatory Index and depression among pregnant and postpartum women: analysis of NHANES 2005-2018.

ABSTRACT:

Background

Perinatal depression, which occurs during pregnancy or after childbirth, is a common and serious complication of pregnancy. Chronic low-grade inflammation has been implicated in the pathophysiology of depression.
