Disparities in diabetes are experienced on the basis of: race/ethnicity, gender, socioeconomic status, age-related vulnerabilities across the lifespan, presence of co-morbidities, and geography. Disparities occur, at least in part, due to inadequate capacity building for translating successful diagnostic, preventive, and therapeutic modalities for individuals and communities at greatest risk. The Atlanta metropolitan area has a rich and diverse population of Black, Hispanic, and South Asian minorities, low socioeconomic status, and low-access communities who have the highest burdens of diabetes in the country. Therefore, the overall goal of the GCDTR's Dispartities core is to facilitate more combined diabetes-disparities translation research that can identify ways to improve engagement in evidence-based diabetes prevention and management interventions among vulnerable populations, and reduce the disproportionately higher risks of morbidity and mortality from diabetes in these groups. Core D provides methodological expertise, sociocultural competencies, access to populations in community, and clinical settings, and relevant databases, tools, and technologies that help investigators explore the drivers of disparities and avenues to address them.
