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 3, 2026
Key finding
A low-cost peer-support lifestyle program improved dietary intake, alcohol use, and physical functioning but did not significantly reduce diabetes incidence at 24 months in high-risk Indians.
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.

Evidence Suggest
- Peer-support lifestyle program improved diet quality and physical functioning at 24 months
- Alcohol use was significantly reduced in the intervention group
- Diabetes incidence was lower but the reduction was not statistically significant
Who this applies to
Adults aged 30-60 years with elevated diabetes risk (IDRS ≥60) in LMIC settings
Keep in Mind
The primary outcome (diabetes incidence) did not reach statistical significance
Between the Lines
- 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
