Combo Diet-Exercise Programs Trim Diabetes Risk

A combination of diet and physical activity programs offered in the community reduce the risk of type 2 diabetes in patients who are at increased risk, according to new federal data.

Programs Help Patients Revert to Normal Glycemic Levels

• Strong evidence suggests that a combination of diet and physical activity programs can reduce new-onset diabetes for persons at increased risk for type 2 diabetes.

• These programs also increase the likelihood of reversion to normal glycemic levels and improve diabetes and cardiovascular disease risk factors, including weight, blood glucose levels, blood pressure, and lipid levels.

• The US Community Preventive Services Task Force recommends the use of combined diet and physical activity promotion programs to reduce progression to type 2 diabetes in those at increased risk.

Combined Program’s Critical Components

• Critical components of a combined diet and physical activity program include trained providers in clinical or community settings who work directly with program participants for at least 3 months; some combination of counseling, coaching, and extended support; and multiple sessions related to diet and physical activity, delivered in person or by other methods.

• Programs also may use 1 or more of the following: diet counselors in various specialties (eg, nutritionists, dietitians, and diabetes educators); exercise counselors in various specialties (eg, physical educators, physiotherapists, and trainers); physicians, nurses, and trained laypersons; a range of intensity of counseling, with many or few sessions, longer- or shorter-duration sessions, and individual or group sessions; and individually tailored or generic diet or physical activity programs.

• Programs should include specific weight-loss or exercise goals and a period of maintenance sessions after the primary core period of the program.

US Task Force Conducts Systematic Review

• The task force recommendation is based on evidence from a systematic review of 53 studies that described 66 programs.

• Most programs used a combination of in-person individual and group sessions.

• Almost all programs led to weight loss, reduced risk of diabetes, or both.

• More intensive programs led to more weight loss and less development of diabetes.

Group Programs More Cost-effective

• These diet-exercise programs were cost-effective; group-based programs were the most cost-effective.

• Health care providers usually are the primary resource for patients at increased risk for type 2 diabetes.

• The task force suggests that health care providers keep informed about local prevention programs offered by community centers or run by insurers or nonprofit or other private contractors.

Take-home Message:

• A federal task force’s systematic review found combined diet and physical activity programs can help prevent or delay the development of diabetes.
