Effects of a digitally-enabled healthy eating and physical activity diabetes prevention peer support program on weight over 6-months

Background/Objectives: Type 2 diabetes (T2D) is a growing health epidemic. Innovative approaches such as digital technologies incorporating peer-supported coaching have shown promise in diabetes prevention. This study aimed to examine the feasibility and effect on weight of a digitally-enabled peer support program in inner-regional Sydney. Methods: A pre-post study of a digitally-enabled peer support initiative promoted weight management and lifestyle changes in participants at risk of T2D in inner-regional Sydney. Participants were recruited primarily from general practices and community groups. Participants received initial guidance, educational videos, goal-setting tools, and self-assessment weights, while volunteer peer support facilitators provided ongoing support through action planning and monthly calls. Baseline and follow-up weights at 6 months were collected to determine program effectiveness, while feasibility was evaluated through short exit interviews and analytic website data. Results: Most eligible participants (92.4%) were recruited through general practice. Program completers (n = 35, 43.8%) reported an average weight reduction of 3.7 kg (SD = 3.9, p < 0.001). Those who used the platform to log at least one achievement saw a greater reduction in weight than those who did not log achievements (mean difference = −2.9 kg, 95% CI −5.6 to −0.1, p = 0.049). Exploratory qualitative analysis of exit interviews revealed challenges surrounding technology, website interaction, scheduling conflicts, data collection, and attrition. Conclusions: Preliminary results indicate that this digital program was associated with significant weight reduction among individuals at risk of diabetes in an inner-regional area of Sydney. Recruitment was most effective via general practices, highlighting the potential for such a program to be promoted through this setting.
