Long-term effects of a lifestyle intervention on weight and cardiovascular risk factors in individuals with type 2 diabetes mellitus: four-year results of the Look AHEAD trial.
BACKGROUND Lifestyle interventions produce short-term improvements in glycemia and cardiovascular disease ( CVD ) risk factors in individuals with type 2 diabetes mellitus , but no long-term data are available . We examined the effects of lifestyle intervention on changes in weight , fitness , and CVD risk factors during a 4-year study . METHODS The Look AHEAD ( Action for Health in Diabetes ) trial is a multicenter r and omized clinical trial comparing the effects of an intensive lifestyle intervention ( ILI ) and diabetes support and education ( DSE ; the control group ) on the incidence of major CVD events in 5145 overweight or obese individuals ( 59.5 % female ; mean age , 58.7 years ) with type 2 diabetes mellitus . More than 93 % of participants provided outcomes data at each annual assessment . RESULTS Averaged across 4 years , ILI participants had a greater percentage of weight loss than DSE participants ( -6.15 % vs -0.88 % ; P < .001 ) and greater improvements in treadmill fitness ( 12.74 % vs 1.96 % ; P < .001 ) , hemoglobin A(1c ) level ( -0.36 % vs -0.09 % ; P < .001 ) , systolic ( -5.33 vs -2.97 mm Hg ; P < .001 ) and diastolic ( -2.92 vs -2.48 mm Hg ; P = .01 ) blood pressure , and levels of high-density lipoprotein cholesterol ( 3.67 vs 1.97 mg/dL ; P < .001 ) and triglycerides ( -25.56 vs -19.75 mg/dL ; P < .001 ) . Reductions in low-density lipoprotein cholesterol levels were greater in DSE than ILI participants ( -11.27 vs -12.84 mg/dL ; P = .009 ) owing to greater use of medications to lower lipid levels in the DSE group . At 4 years , ILI participants maintained greater improvements than DSE participants in weight , fitness , hemoglobin A(1c ) levels , systolic blood pressure , and high-density lipoprotein cholesterol levels . CONCLUSIONS Intensive lifestyle intervention can produce sustained weight loss and improvements in fitness , glycemic control , and CVD risk factors in individuals with type 2 diabetes . Whether these differences in risk factors translate to reduction in CVD events will ultimately be addressed by the Look AHEAD trial . TRIAL REGISTRATION clinical trials.gov Identifier : NCT00017953
