Findings are subject to incomplete reporting and heterogeneity of studies included , and confounding because most included studies used pre-post study design s. CONCLUSIONS DPP lifestyle modification programs achieved clinical ly meaningful weight and cardiometabolic health improvements .
Together , these data suggest that additional value is gained from these programs , reinforcing that they are likely very cost-effective
BACKGROUND The Diabetes Prevention Program ( DPP ) study showed that weight loss in high-risk adults lowered diabetes incidence and cardiovascular disease risk .
No prior analyses have aggregated weight and cardiometabolic risk factor changes observed in studies implementing DPP interventions in non research setting s in the United States .
Prevention of type 2 diabetes mellitus by changes in lifestyle among subjects with impaired glucose tolerance.
BACKGROUND Type 2 diabetes mellitus is increasingly common , primarily because of increases in the prevalence of a sedentary lifestyle and obesity . Whether type 2 diabetes can be prevented by interventions that affect the lifestyles of subjects at high risk for the disease is not known . METHODS We r and omly assigned 522 middle-aged , overweight subjects ( 172 men and 350 women ; mean age , 55 years ; mean body-mass index [ weight in kilograms divided by the square of the height in meters ] , 31 ) with impaired glucose tolerance to either the intervention group or the control group . Each subject in the intervention group received individualized counseling aim ed at reducing weight , total intake of fat , and intake of saturated fat and increasing intake of fiber and physical activity . An oral glucose-tolerance test was performed annually ; the diagnosis of diabetes was confirmed by a second test . The mean duration of follow-up was 3.2 years . RESULTS The mean ( + /-SD ) amount of weight lost between base line and the end of year 1 was 4.2+/-5.1 kg in the intervention group and 0.8+/-3.7 kg in the control group ; the net loss by the end of year 2 was 3.5+/-5.5 kg in the intervention group and 0.8+/-4.4 kg in the control group ( P<0.001 for both comparisons between the groups ) . The cumulative incidence of diabetes after four years was 11 percent ( 95 percent confidence interval , 6 to 15 percent ) in the intervention group and 23 percent ( 95 percent confidence interval , 17 to 29 percent ) in the control group . During the trial , the risk of diabetes was reduced by 58 percent ( P<0.001 ) in the intervention group . The reduction in the incidence of diabetes was directly associated with changes in lifestyle . CONCLUSIONS Type 2 diabetes can be prevented by changes in the lifestyles of high-risk subjects
