ABSTRACT Rates of gestational diabetes (GDM) are rising nationwide, particularly affecting people of color. Despite similar rates among non-Hispanic White and Black women, Black women have more than double the risk of developing type 2 diabetes (T2DM) after GDM as compared to White women. This contributes to disproportionately high maternal morbidity and mortality rates in the US, especially among Black birthing individuals. Digital health interventions show promise in improving health, healthcare, and patient satisfaction, but tailored interventions for the Black community are lacking, highlighting the need for inclusivity. This research project expands upon the foundation laid by the parent award by building the evidence base for digital health interventions, particularly for Black birthing people with GDM who face markedly elevated risk for T2DM. This Diversity Supplement proposal for the candidate, Ijeoma Uche, MPH, focuses on patient-centered digital interventions in diverse populations at high risk for T2DM with the following Specific Aims. Aim 1. Conduct a comprehensive narrative review of randomized clinical trials that have tested digital/mHealth interventions for postpartum populations at risk for T2DM, with a focus on diverse individuals with prior GDM. Aim 2. Conduct a process evaluation of the parent trial, including participants' engagement in and acceptability of the digital health intervention and trial procedures. Aim 3. Convene a Research Advisory Group of Black postpartum participants from the parent trial and clinical and health system stakeholders to assess perspectives on the digital intervention and trial procedures, with the goal of informing future research in this area. These activities are integral to the parent grant goals and will provide the necessary research training, mentoring, and experience to build the candidate’s research career as a physician-scientist focused on digital interventions for maternal health equity.
