Purpose This article addresses the gap between research and practice by describing the feasibility and outcomes of an evidence-based diabetes self-management health education program. The Healthy Changes™ program used a peer-led group format to promote physical activity and healthful eating practices, employing culturally relevant materials and measures. Methods Older adults (mean age = 69.2 years; SD = 10.7) with type 2 diabetes (N = 243) were recruited from nine communities to participate in the Healthy Changes™ program. Components included goal setting, problem solving, group support, and interactive lectures from experts. Measures of eating patterns, physical activity, body weight, community resources, self-rated health, and self-efficacy were administered at baseline, and at 4, 8, and 12 months. Results Participants attended on average 13 weekly sessions, and showed improvements in health behaviors, supportive resources, and self-efficacy at 4, 8, and 12 months. Conclusion The Healthy Changes™ program can be successfully translated into community settings and led by trained peer leaders, yielding health improvements similar to those reported in efficacy trials. Trained peer leaders are key to effective program implementation. Peer-led groups enhance goal attainment by giving participants a venue to discuss obstacles and strategize solutions.
