We evaluated a community-based physical activity intervention in Georgia senior centers. Participants were a convenience sample that completed the pre-test only (n = 592), or the pre-test, the intervention, and a post-test (n = 418, 98% aged 60 and older, mean age = 75, 83% female, 56% black). The 4-month physical activity intervention, based on the Health Belief Model, included 16 sessions that focused on educator-led chair exercises, promotion of walking, using a pedometer, and recording daily steps. Pre- and post-tests assessed physical activity and physical function, categorized as poor, moderate, or good (Short Physical Performance Battery). Following the intervention, participants improved their physical function (good physical function at pre-test vs. post-test: 16.5% vs. 25.3%, P < or = 0.001), increased minutes of physical activity by 26% (P < or = 0.001) and step counts by 29% (P < or = 0.0001, sub-sample, n = 95), and decreased reports of "it's not safe" as a barrier to physical activity (P < or = 0.05). Increased physical activity (P < or = 0.01) was associated with improved physical function following the intervention. The results of this evaluation provide an evidence base for the effectiveness of this community intervention for improving physical activity and physical function in older adults.

Our purpose was to evaluate a community-based fruit and vegetable intervention conducted in rural and urban areas of Georgia. Participants were a convenience sample from Georgia senior centers that completed a pre-test, the intervention, and a post-test (N = 558, mean age = 75, 83% female, 47% white, 53% black). The 4-month intervention had eight sessions focused on practical ways to increase intake of fruits and vegetables at meals and snacks and included physical activity. Pre- and post-tests examined self-reported intakes of fruits and vegetables at breakfast, lunch, the evening meal, and snacks, knowledge of recommended intakes, and barriers to intake. Following the intervention, the number of participants reporting consumption of at least 7 servings of fruits and vegetables daily increased by 21-percentage points (P < or = 0.001), knowledge that 7 to 10 servings of fruits and vegetables are recommended daily (for 1,600 to 2,200 calories) increased from 7% to 57% (P < or = 0.001), and three barriers to fruit and vegetable intake decreased (P < or = 0.05): "difficulties with digestion," "too many are recommended," and "too much trouble." Regression analyses indicated that increased intake following the intervention was independently associated with living in more urban rather than rural areas, improved knowledge of intake recommendations, decrease in perception of cost as a barrier, and increase in digestive problems as a barrier (P < or = 0.05). These results provide an evidence base for the effectiveness of this community intervention for improving knowledge and intake and decreasing barriers to fruit and vegetable intake in older adults.

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.
