Early, aggressive glucose control in prediabetes protective: from the Lancet.
In fact, even a transient reversion to normal glucose regulation was associated with a significantly reduced risk of diabetes among participants in the DPP, a major randomized trial comparing weight loss and dietary changes with drug therapy for preventing the onset of type 2 diabetes.
Compared with 1,096 participants in that multicenter trial who consistently had prediabetes, the risk of diabetes was 56% lower (hazard ratio, 0.44) among 894 individuals who had returned to normal glucose regulation during the intervention period, according to findings from the Diabetes Prevention Program Outcomes Study (DPPOS), an ongoing post intervention observational study, Dr. Leigh Perreault of the University of Colorado, Aurora.
"Diabetes risk reduction was strongly associated with the number of times normal glucose regulation was achieved. Specifically, diabetes risk was reduced 47% in DPPOS if normal glucose regulation was attained only once (HR, 0.53); 61% if it was reached twice (HR,0.39); and 67% if it was reached three times (HR, 0.33)," the investigators said (Lancet 2012 June 9 [doi: 10.106/S0140-6736(12)60525-X]).
At baseline, all 3,234 participants were at risk for developing diabetes. They were randomized to receive lifestyle interventions, metformin treatment, or placebo, and were followed for a median of 3.2 years during the intervention.
The current analysis, at a median follow-up of 5.7 years, shows that the reduced risk for diabetes among those subjects who returned to normal glucose regulation during the intervention was not affected by group assignment, they said.
Those who consistently had prediabetes during DPP--despite intensive lifestyle interventions--had an increased risk of developing diabetes compared with those who didn't have prediabetes and who were in the placebo group (HR, 1.31).
The findings suggest that maintenance of prediabetes despite intensive lifestyle modification represents a high-risk state that may warrant additional interventions, they said.
"These data serve as essential clinical information to support early and aggressive measures for long-term prevention of diabetes in people at risk," they concluded.
