Abstract:
Objective To investigate if improving or slowing the progression of glucose intolerance might be linked with the reduction of cardiovascular disease(CVD)events and mortality in a Da Qing population with prediabetes.Methods In 1986,577 subjects with impaired glucose tolerance in 33 clinics in Daqing city were randomly assigned to either the control group or one of three lifestyle intervention groups(diet,exercise,or diet plus exercise)to receive a 6 year lifestyle intervention.All the participants were followed for 14 years(1993-2006)after completion of the 6 year active interventions to assess the long-term effect of the interventions.In this post-hoc analysis,the participants were stratified into four subgroups(quartiles)based on their 2 h plasma glucose(2hPG)level after glucose loading at the end of the active intervention,in order to analyze the impact of plasma glucose level on CVD events and mortality.Results During the 20-year follow-up,there were a total of 142 deaths(68 of which were attributed to CVD)and 211 first CVD events(145 strokes and 66 myocardial infarctions).From the highest to the lowest levels of 2hPG in the 4 quartiles,the all-cause mortality(17.8,12.7,10.9,and 9.7/1 000 personyears),CVD mortality(9.1,5.9,6.1,and 4.9/1 1300 person-years)and the incidence of first CVD events(30.4.24.0,18.8,and 19.7/1 000 person-years)showed a clear trend of decline.In multivariate analyses,controlled for age,sex,body mass index,smoking habit,blood pressure,and intervention methods at baseline,the results showed that the 5 mmol/L elevation of 2hPG level after glucose loading in 1992 significantly increased the all-cause mortality(HR 1.335.P=0.005),the incidences offirst CVD events(HR 1.227,P=0.012)and stroke(HR 1.213,P=0.026).Conclusion In pre-diabetes population.if the lifestyle intenrentions are substantially efficacious in improving glucose intolerance,the CVD risk and mortality will be reduced.
