Study Description

The Action for Health in Diabetes (Look AHEAD) is a randomized trial comparing the effects of Intensive Lifestyle Intervention (ILI) focused on weight loss achieved through healthy eating and increased physical activity versus a control condition of Diabetes Support and Education (DSE) in overweight and obese individuals with type 2 diabetes. The Look AHEAD Extension (LA-E) will examine whether ILI, provided for 10 years during mid-life, has enduring benefits that persist beyond the period of the intervention for older individuals with diabetes.

The primary aims of LA-E are to test whether ILI relative to DSE has long term legacy effects on
1) increased lifespan and 2) reduced health care costs.

Secondary aims test whether ILI relative to DSE has long-term effects on key dimensions of healthy aging: less frailty, reduced diabetic microvascular complications, and improved quality of life. LA-E will also compare long-term trajectories of weight, physical activity, fat and lean mass, and bone density and examine how these are related to outcomes.

LA-E focuses on the clinical outcomes most relevant to healthy aging and resilience and will provide the long-term data needed to frame guidelines related to lifestyle intervention in the care of older overweight or obese individuals with type 2 diabetes.
