Roughly 88 million adults have prediabetes and over 84% are unaware that they even have prediabetes. African-Americans have an increased risk of being diagnosed with prediabetes. Faith-based organizations have a history of serving as a primary source of social support for African-Americans. Parishioners with prediabetes from four African-American churches participated in free, evidence-based group coaching to learn how to manage and control risk factors associated with type 2 diabetes. The weekly group coaching sessions took place at a local church and they were co-facilitated by two trained professionals: a lifestyle coach and a nurse practitioner. At the conclusion of the 16-week group coaching sessions, participants had a decrease in hemoglobin A1C levels, an increase in minutes of physical activity per week, and an improvement in knowledge and behavior.
