    Abstract:
    A community-based intervention to improve diabetes self-management (DSM) and decrease A1c in older adults with diabetes from Georgia senior centers was evaluated. Participants were a convenience sample that completed the pre-test questionnaire only (N = 351) and a subset that completed the pre-test, intervention, and post-test questionnaires and A1c measurements (n = 144, mean age = 74 years, 84% female, 42% white, 57% black). Incorporating principles of the Health Belief Model and National Standards for DSM, the 4-month intervention consisted of eight sessions focused on improving daily adherence to DSM behaviors and included physical activity. At the post-test, several DSM behaviors increased by > or = 1 day/week: following a healthy eating plan, following an eating plan prescribed by their doctor, eating five or more servings of fruits and vegetables daily, spacing carbohydrates, and inspecting the insides of shoes (P < or = 0.0001). The mean decrease in A1c for the entire sample was 0.25% (SD = 0.82, P < or = 0.001, n = 144) and those with an initial A1c > 8% had a clinically significant mean decrease of 1.15% (SD = 1.09, pre-test: 9.48% vs. 8.33%, P < or = 0.001, n = 24). Increased physical activity was the DSM behavior consistently associated with decreased A1c in regression analyses (P < or = 0.05). The results of this evaluation provide an evidence base for the effectiveness of this community intervention in decreasing A1c and improving DSM behaviors in older adults.
