Purpose of Review <p>The rates of diabetes in pregnancy (type 1, type 2, and gestational diabetes) are increasing. Diabetes in pregnancy is associated with increased risk for maternal and neonatal complications. Certain groups are disproportionately affected by these complications and this paper reviews the data about disparities in diabetes in pregnancy and explores the social determinants of health (SDoH) underlying these disparities.</p> Recent Findings <p>Rates of diagnosis of gestational diabetes and pregestational diabetes are higher in racial and ethnic minority groups and people with socioeconomic disadvantage. There is higher all cause maternal mortality for Black people compared to White people. Emerging data suggests higher risk for adverse pregnancy outcomes for Black, American Indian, and Hispanic/Latina subjects with diabetes compared to White subjects. Individuals living in neighborhoods with higher poverty and less educational attainment also have higher rates of pregnancy and neonatal complications with diabetes.</p> Summary <p>Diabetes in pregnancy is a complex condition which requires specialty care that can be time-consuming and costly. Individuals with disadvantages in income and employment, food security, social protection and support, and access to affordable and quality health services may be particularly susceptible to adverse outcomes of diabetes in pregnancy. Providers can reduce disparities by recognizing individuals with vulnerabilities in SDoH and tailoring treatment to social context. Equitable access to diabetes technology and postpartum care can also reduce disparities in outcomes.</p>
