Maternal Obesity and Perinatal Depression: An Updated Literature Review.

The objective of this review was to determine if there is an association between maternal obesity and increased risk of perinatal depression. Original research articles were found by conducting an electronic database search of PubMed, ClinicalKey, PsycINFO, and Cochrane Library. Seven articles, published in the last five years, were reviewed. Of the seven articles, five demonstrated an association between some level of maternal obesity and increased risk of perinatal depressive symptoms. The two remaining articles did initially find an association, but it was no longer significant after adjusting for or mediating the analysis with covariates. There appears to be an association between peripartum depressive symptoms and some level of maternal obesity and its comorbidities. More research is needed to determine the mechanism and degree of the association and its clinical significance.
