BACKGROUND/OBJECTIVES Improving glycemic control in older African Americans with diabetes and mild cognitive impairment (MCI) is important as the population ages and becomes more racially diverse. DESIGN Randomized controlled trial. SETTING Recruitment from primary care practices of an urban academic medical center. Community‐based treatment delivery. PARTICIPANTS Older African Americans with MCI, low medication adherence, and poor glycemic control (N = 101). INTERVENTIONS Occupational therapy (OT) behavioral intervention and diabetes self‐management education. MEASUREMENTS The primary outcome was a reduction in hemoglobin A1c level of at least 0.5% at 6 months, with maintenance effects assessed at 12 months. RESULTS At 6 months, 25 of 41 (61.0%) OT participants and 22 of 46 (48.2%) diabetes self‐management education participants had a reduction in hemoglobin A1c level of at least 0.5%. The model‐estimated rates were 58% (95% confidence interval [CI] = 45%‐75%) and 48% (95% CI = 36%‐64%), respectively (relative risk [RR] = 1.21; 95% CI = 0.84‐1.75; P = .31). At 12 months, the respective rates were 21 of 39 (53.8%) OT participants and 24 of 49 (49.0%) diabetes self‐management education participants. The model‐estimated rates were 50% (95% CI = 37%‐68%) and 48% (95% CI = 36%‐64%), respectively (RR = 1.05; 95% CI = 0.70‐1.57; P = .81). CONCLUSION Both interventions improved glycemic control in older African Americans with MCI and poor glycemic control. This result reinforces the American Diabetes Associationʼs recommendation to assess cognition in older persons with diabetes and demonstrates the potential to improve glycemic control in this high‐risk population.
