- Lifestyle intervention in people with impaired glucose tolerance (IGT) effectively reduces cardiovascular disease (CVD) incidence.
- A 6+-year delay in type 2 diabetes (T2D) onset offers CVD and microvascular benefits, say researchers.
Why this matters
- People with IGT are at greatly increased risk for T2D, along with increased CVD and microvascular complications risk.
- Using lifestyle changes to ward off T2D can also reduce the CVD and vascular risks.
- 30-year cumulative CVD incidence (all 95% CIs):
- Intervention: 51.8% (47.1-56.5).
- Control: 65.7% (57.8-73.6).
- CVD incidence per 1000 person-years:
- Intervention: 21.8 (18.8-25.1).
- Control: 29.0 (23.0-36.2).
- Adjusted for clinic, risk for first CVD event with intervention was reduced by 27% (HR 0.73; 95% CI, 0.55-0.96; P=.024).
- Reverting to normal glucose tolerance (174/576) not surprisingly also reduced risk.
- Data analyzed for 576 participants in randomized 6-year Da Qing Diabetes Prevention Study (1986-1992), followed for up to 30 years after participating in diet, exercise, diet+exercise, or neither (control).
