Effects of a Digitally-Enabled Healthy Eating and Physical Activity Diabetes Prevention Peer Support Program on...

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.

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.

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.

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.
