Does depression increase the risk of gestational diabetes mellitus? A systematic review and meta-analysis

Abstract

Objective: Data on the relationship between depression and gestational diabetes mellitus (GDM) is scarce and conflicting. We, hereby, aimed to review evidence if prior depression increases the risk of GDM.

Methods: PubMed, Embase, CENTRAL, and Google Scholar databases were searched from inception to 11th September 2021 for English language studies reporting the relationship between depression and subsequent risk of GDM.

Results: Ten studies were included. Meta-analysis of data from nine studies including 127,195 patients indicated that prior depression was associated with a significantly increased risk of GDM (OR: 1.29 95% CI: 1.10, 1.52). There was no change in the significance of the results on sensitivity analysis. On subgroup analysis based on study location, we noted that the association between depression and GDM was seen only in USA-based studies with the pooled analysis of non-USA studies indicating no such relationship. Similar conflicting results were noted on subgroup analysis based on diagnostic criteria for GDM and depression.

Conclusion: Our study indicates that prior depression can lead to a 29% increased risk of GDM in pregnant females. Current evidence is derived from a limited number of studies with significant heterogeneity in the timing and diagnostic criteria for depression.
