A 4‐week community‐implemented diabetes prevention program is associated with improved metabolic outcomes at 12 months after participation
Authors' conclusion
SSBC participation was associated with improvements in key diabetes risk factors at 12-month post-program.
Study context
- Population
- Adults at risk of T2D (HbA1c 39–46 mmol/mol[5.7–6.4%]); mean age 58.8(8.7) years, 61% White, 68% women117 with HbA1c at baseline and 12 months
- Participants
- 389 adults
- Comparison
- Small Steps for Big Changes (SSBC) program, 12 months post-program vs baseline
