Abstract:

Background: Diabetes and hypertension are chronic conditions that are common in pregnancy. However, there are limited data examining pregnancy outcomes in individuals with coexisting hypertensive disorders and diabetes in pregnancy.

Methods: We conducted a retrospective cohort study to assess maternal and neonatal outcomes in singleton pregnancies complicated by diabetes comparing individuals with and without hypertension in our center from 2011 to 2020.

Results: A total of 3170 individuals were included (2.1%, 16.3%, and 81.6% with type 1, type 2, and gestational diabetes, respectively). Fifteen percent of pregnant individuals with diabetes had comorbid hypertension. Pre-existing hypertension was most common with type 2 diabetes while pre-eclampsia was most common with type 1 diabetes. Hypertensive disorders of pregnancy were associated with a longer maternal hospital stay in type 1, 2, and gestational diabetes (5.8+/-4.3 vs. 4.0+/-2.8 days [p=0.046]; 4.8+/-4.0 vs. 3.7+/-2.8 [p=0.0005]; 3.3+/-2.4 vs. 2.6+/-3.5 days [p=0.0002], respectively) but not neonatal length of stay. Hypertension was associated with increased NICU admissions in the type 1 and gestational diabetes groups but not in the type 2 diabetes group. Additionally, hypertension was associated with small for gestational age neonates in the type 2 and gestational diabetes groups (10.4% vs. 4.4%, p=0.01; 12.3% vs. 7.5%, p=0.001; respectively) but not in the type 1 diabetes group.

Conclusions: Comorbid hypertension is associated with longer maternal hospital stay, NICU admission, and small for gestational age neonates in individuals with diabetes in pregnancy.
