The Effects of Race and Socioeconomics on the Relationship Between Gestational Diabetes Mellitus and Birth Outcomes: An Analysis of Southern US PRAMS data

Abstract

Gestational diabetes mellitus (GDM) is one of the most common pregnancy complications. Uncontrolled GDM increases the risk of negative pregnancy outcomes for both the pregnant individual and the infant. African Americans (AAs) have higher maternal morbidity and infant mortality rates than non-Hispanic whites (NHWs). The goal of the current study was to examine racial differences in the effect of GDM on birth outcomes. The data from the Pregnancy Risk Assessment Monitoring System (PRAMS) was analyzed with a focus on four states in the southern U.S. (Alabama, Georgia, Louisiana, and Mississippi). The results presented suggest that AAs are at lower risk of GDM than NHW individuals. Even with the lower risk of GDM, AAs are at higher risk of pre-term births. In addition, socioeconomic factors and access to prenatal care play a role in birth outcomes including moderating the effect of GDM on outcomes. A discussion of potential policy interventions that may improve pregnancy outcomes is discussed including increased use of doulas to support pregnant people.
