Research Summary
Analyzed using Evidence Intelligence™
Peer-support lifestyle program reduces diabetes risk factors but not diabetes incidence in high-risk Indians
Last updated June 11, 2026
Key finding
greater reduction in IDRS score (mean difference: -1.50 points, p=0.022)
This cluster-randomized trial tested a community-based peer-support lifestyle program in 1,007 high-risk Indian adults. The program improved diet, reduced alcohol use, and enhanced physical functioning, but the 14.9% vs 17.1% reduction in diabetes incidence was not statistically significant.

Plain-language summary
What this paper says
A plain-language read of the study’s main message and where it applies.
Study focus
This cluster-randomized trial tested a community-based peer-support lifestyle program in 1,007 high-risk Indian adults. The program improved diet, reduced alcohol use, and enhanced physical functioning, but the 14.9% vs 17.1% reduction in diabetes incidence was not statistically significant.
Clinical relevance
This study demonstrates that a peer-led, community-based lifestyle program can be delivered at very low cost (US$22.50/participant) in a low- and middle-income country setting. While the diabetes incidence reduction was not statistically significant, the improvements in risk factors suggest potential for diabetes prevention at scale with longer-term follow-up.
Keep in mind
Diabetes incidence reduction was not statistically significant No adjustment for multiple comparisons (increases type I error risk) 24-month follow-up may be insufficient to detect diabetes prevention effects
Main Effects
Diabetes incidence: ↓ non-significant (14.9% vs 17.1%, RR 0.88, p=0.36)
IDRS score: ↓ -1.50 points (p=0.022)
Alcohol use: ↓ RR 0.77 (p=0.018)
