Look AHEAD Results Favor Intensive Lifestyle Intervention

At four years, this diabetes intervention beats education for CVD risk factor reduction

TUESDAY, Sept. 28 (HealthDay News) -- Intensive lifestyle intervention (ILI) for patients with type 2 diabetes can result in sustained improvements in cardiovascular risk factors and in fitness, according to a report published in the Sept. 27 issue of the Archives of Internal Medicine.

Rena R. Wing, Ph.D., of Brown Medical School in Providence, R.I., and other members of The Look AHEAD Research Group reported four-year results of the ongoing trial, which was designed to obtain long-term data on the effects of ILI compared to diabetes support and education (DSE; the control group) on changes in weight, fitness, and cardiovascular disease risk factors.

Averaged across the four years, the researchers found that ILI patients had significantly greater improvements in weight, treadmill fitness, hemoglobin A1c level, high-density lipoprotein cholesterol, triglycerides, and blood pressure. Low-density lipoprotein cholesterol was more improved in the DSE group, a finding related to greater use of lipid-lowering medications in the DSE group.

"ILI can produce sustained weight loss and improvements in fitness, glycemic control, and cardiovascular disease risk factors in individuals with type 2 diabetes. Whether these differences in risk factors translate to reduction in cardiovascular disease events will ultimately be addressed by the Look AHEAD trial," the authors write.

One author disclosed serving on a scientific advisory committee for Free & Clear and financial relationships with BodyMedia Inc., UPMCHealth Plan, and Proctor & Gamble.
