The Association of Immigrant Status, Preeclampsia, and Gestational Age at Delivery among Black Women with Diabetes in California Público

Abstract

Purpose: Black women are at higher risk for pregestational diabetes (PGDM), gestational diabetes (GDM), and preterm birth (PTB, < 37 completed weeks’ gestation). Foreign-born women have lower risk of PTB. We examined associations between immigrant status, maternal, social, and obstetric characteristics, and risk of PTB among Black women with any diabetes.

Methods: From 3,160,268 California live births, 2007-2012, we assessed 7,024 singleton PTBs or full term births (39-40 weeks) from non-Hispanic Black (NHB) diabetic women. We examined crude (cOR) and adjusted odds ratios (aOR) with stepwise backward logistic regression and 95% confidence intervals (CIs).

Results: Foreign-born status was associated with a lower risk of PTB [OR 0.51 (95% CI 0.43, 0.61)]. U.S.-born women, compared to Foreign-born women, were more likely to have some characteristics associated with PTB (< 25 years of age, < 12 years of education, Medicaid-paid delivery, uterine tract infection (UTI), smoking, preeclampsia, and obesity (BMI >30). The greatest cORs for PTB were for preeclampsia [7.52(6.41, 8.83)], smoking [1.67(1.42, 1.96)], and obesity [1.22(1.05, 1.40)]. After adjustment, aOR for PTB among Foreign-born births was 0.56(0.44, 0.71).

Conclusions: Foreign-born status is protective of PTB among NHB diabetic women. Further research is needed on preeclampsia, smoking, obesity, and structural racism.
