[Association between Gestational Diabetes Mellitus and Postpartum Depressive Episode].

Objective To explore the association between gestational diabetes mellitus (GDM) and postpartum depressive (PPD) episode and the influencing factors of PPD episode. Methods The clinical data of pregnant women who filed in the Department of Obstetrics,Peking Union Medical College Hospital from March 1,2020 to February 28,2021 were collected.Oral glucose tolerance test (OGTT,75 g) and determination of glycosylated hemoglobin (HbA1c) were carried out in the second trimester,and fasting blood glucose and glycosylated albumin (GA) were determined in the third trimester.Mini-International Neuropsychiatric Interview (MINI,5.0 Chinese version) was used to diagnose depressive episode and anxiety disorder within (42±7) days after delivery.We analyzed the influencing factors of PPD episode by multiple Logistic regression to explore the relationship between GDM and PPD episode.Fasting glucose and GA in the third trimester,as well as the incidence of PPD episode,between women with and without GDM were compared. Results The GDM,75 g OGTT,and HbA1c in the second trimester,as well as fasting blood glucose and GA in the third trimester,showed no significant differences between the PPD group and the non-PPD group (all P>0.05).Postpartum generalized anxiety disorder (OR=4.656,95%CI=1.130-19.184, P=0.033),obsessive-compulsive disorder (OR=11.989,95%CI=1.004-143.113, P=0.049),and the history of mental disorder before pregnancy (OR=13.567,95%CI=2.191-83.991, P=0.005) were the risk factors of PPD episode.The fasting blood glucose and GA in the third trimester,the incidence of PPD episode,and the PPD episode comorbidities of generalized anxiety disorder and obsessive-compulsive disorder had no significant differences between pregnant women with and without GDM (all P>0.05).Conclusions There is no association between GDM and PPD episode under routine blood glucose management. Special attention should be paid to pregnant women with a history of mental disorder before pregnancy.
