Abstract

Diabetes mellitus (pregestational (PDM) and gestational (GDM)) is associated with adverse pregnancy outcomes (APOs). However, studies exploring the association of APOs with maternal glycemia among women without PDM/GDM are limited. We utilized data from 4119 women (307—PDM; 582—GDM; 3230—non‐PDM/GDM) in the Boston Birth Cohort (1998–2016). Women in the non‐PDM/GDM group were subdivided by tertiles of 1 h, 50 g oral glucose load test at 24–32 weeks: T1: 50–95 mg/dL (n = 1166), T2: 96–116 mg/dL (n = 1151), T3: 117–201 mg/dL (n = 913). Using multivariable logistic regression, we examined the association of maternal glycemia with APOs— preterm birth (PTB) and hypertensive disorders of pregnancy (HDP)—and adverse perinatal out-comes—high birth weight (HBW), cesarean section (CS), and sub‐analyses by race‐ethnicity. Compared to women in T1, women in T2 and T3 had a higher prevalence of pre‐existing hypertension (T1: 2.8% vs. T2: 5.2% vs. T3: 6.3%) and obesity (T1: 13.3% vs. T2: 18.1% vs. T3: 22.9%). Women in T2 and T3 had higher odds of HBW (adjusted odds ratio aOR T2: 1.47 [1.01–2.19] T3: 1.68[1.13–2.50]) compared to women in T1. Additionally, women in T2, compared to T1, had higher odds of HDP (aOR 1.44 [1.10–1.88]). Among non‐Hispanic Black (NHB) women, those in T2 and T3 had higher odds of HDP compared to T1 (aOR T2 1.67[1.13–2.51]; T3: 1.68[1.07–2.62]). GDM and PDM were associated with higher odds of HBW, CS, PTB, and HDP, compared to women in T1. In this pre-dominantly NHB and Hispanic cohort, moderate maternal glycemia without PDM/GDM was associated with higher odds of HBW and HDP, even more strongly among NHB women. If confirmed, a review of current guidelines of glucose screening and risk stratification in pregnancy may be war-ranted.
