NCT00017953

Brief Summary

The Look AHEAD study is a multi-center, randomized clinical trial to examine the long-term effects of a lifestyle intervention designed to achieve and maintain weight loss. The study will investigate the effects of the intervention on heart attacks, stroke and cardiovascular-related death in individuals with type 2 diabetes who are also overweight or obese.

Outcome Measures

Primary Outcomes (1)

  • First Occurrence of a Severe Cardiovascular Event

    Number of participants with first on-study occurrence of one of the following major cardiovascular events: fatal and non-fatal myocardial infarctions and strokes, hospitalizations for angina, and cardiovascular deaths

    up to 11 years

Secondary Outcomes (3)

  • First Occurrence of Cardiovascular Death, Myocardial Infarction, or Stroke

    up to 11 years

  • First Occurrence of Death, Myocardial Infarction, or Hospitalized Angina

    up to 11 years

  • First Occurrence of Major Clinical Events

    up to 11 years

Study Arms (2)

Lifestyle Intervention

EXPERIMENTAL

Participants in the lifestyle intervention arm are offered individual and group sessions designed to help achieve and maintain weight loss.

Behavioral: Lifestyle Intervention

Diabetes Support and Education

ACTIVE COMPARATOR

The diabetes support and education arm provides group sessions on diabetes management and social support.

Behavioral: Diabetes Support and Education

Interventions

The lifestyle intervention is implemented with individual supervision and group sessions and is aimed at achieving and maintaining at least a 7% decrease in weight from baseline and 175 minutes per week in physical activity. It is implemented during a four-year period with the most intensive application during the first year, less frequent attention during the next three years, and a minimum of twice yearly contacts during an extended follow-up period. To help participants achieve and maintain weight loss, a variety of diet strategies (e.g. prepared meals and liquid formula), exercise strategies, and optional weight loss medications are utilized based on a preset algorithm and participant progress.

Lifestyle Intervention

Participants assigned to diabetes support and education are offered three sessions each year in diabetes management and social support.
