Objective: To determine whether inter-pregnancy weight loss is associated with improved perinatal outcomes among pregnancies complicated by recurrent diabetes.
Methods: We performed a retrospective cohort study of all women with at least 2 singleton pregnancies complicated by gestational (GDM) or type 2 (T2DM) and cared for by the Resident Diabetes in Pregnancy Clinic at a large tertiary referral center from 2007-2017. Women whose initial pregnancy weight decreased between pregnancies were compared to those whose weight stayed the same or increased. Demographic characteristics were compared between groups and logistic regression was used to control for potential confounding variables including maternal age, race, and depression.
Results: There were 62 pregnancies complicated by recurrent diabetes during the study period. Weight loss between pregnancies occurred in 24 women. Women with pregnancies with inter-pregnancy weight loss were older (31.6 vs. 27.6, p=0.01) and had higher early pregnancy Edinburgh Postnatal Depression Scale scores (median 7; IQR 5,8 vs. median 2; IQR 1, 3, =0.01). Adjusted analyses using logistic regression demonstrated no significant association between inter-pregnancy weight loss and adverse maternal/neonatal outcomes including large for gestational age, small for gestational age, cesarean section, shoulder dystocia, birth injury, NICU admission>24 hours, and preterm birth.
Conclusions: Inter-pregnancy weight loss was not associated with improved maternal or neonatal outcomes among pregnancies complicated by GDM or T2DM. Future studies are needed to identify the impact of depression on gestational weight gain/loss and subsequent pregnancy outcomes.
