Guideline-recommended postpartum screening is a critical step toward diabetes prevention after a diagnosis of gestational diabetes mellitus (GDM). However, patient uptake of postpartum screening remains suboptimal and uneven across racial/ethnic groups. This creates a missed opportunity for diabetes prevention or early treatment, particularly among minority women at highest risk. The goals of this project are to identify, refine, and assess the acceptability of individual components of a theory-driven outreach intervention that is feasible to implement in health system settings and designed to motivate racially/ethnically diverse women with GDM to complete postpartum screening. The results will inform future research aimed at equitably increasing screening uptake among diverse women at high risk for diabetes.
