Lifestyle and Metformin Interventions and Risk of Multimorbidity in Adults With Prediabetes
Authors' conclusion
Among adults with prediabetes at baseline, lifestyle intervention, but not metformin, was associated with a lower burden of multimorbidity.
Study context
- Population
- Adults with prediabetes at high risk of diabetes enrolled in Diabetes Prevention Program (DPP)/DPP Outcomes Study (DPPOS), 27 US sites, with CMS morbidity data through 2021; median age 74 years, 68% femalewith CMS data
- Participants
- 1,173 adults
- Comparison
- Intensive lifestyle intervention or metformin vs placebo
- Lifestylen = 385
- Metforminn = 385
- Placebon = 403reference
- Primary endpoint
- Multimorbidity (≥2 of 15 prevalent conditions defined in CMS' Chronic Condition Data Warehouse)
- Follow-up
- Through 2021
