Metformin Reduces Risk of Diabetes by 22%, Results of Latest Meta-analysis
The addition of metformin to intensive Lifestyle Modifications (LSM) is an effective value addition among patients with pre-diabetes at high risk of progression to T2DM, a recent systematic review and meta-analysis study has concluded.
This study has been published in the June 2024 issue of Clinical Diabetology, Via Medica Journals.
The meta-analysis included 8,869 patients with prediabetes. Patients were grouped into two interventions- 4,328 in the metformin arm and 4,541 in the control arm (lifestyle modification/placebo).
Key highlights from the meta-analysis include:
- The use of metformin resulted in a 22% relative risk reduction in the progression from prediabetes to diabetes compared to lifestyle modification and/or placebo.
This meta-analysis concludes that early intervention with metformin reduces the risk of type 2 diabetes in high-risk individuals with prediabetes1 . The huge global burden of prediabetes with an approximate 25% rate of conversion to diabetes represents the tip of the “sugary” iceberg.
These findings also co-relate with the most recently published analysis of UKPDS with regards to early intervention with metformin in T2D. Over the largest 42-year follow-up, the study showed that intensive glycemic control with metformin, compared to conventional glycemic control, led to a 20% reduction in the risk of death from any cause and a 31% reduction in the risk of myocardial infarction2.
