Evaluation of Group Lifestyle Balance Maintenance Strategies

Summary

Heart disease is a leading cause of death in people in the United States. It is a major problem for those with diabetes. Conditions called the metabolic syndrome and pre-diabetes increase risk for diabetes and heart disease. The metabolic syndrome is a group of disorders that occur at the same time. Overall, one in four American adults has the metabolic syndrome. It is more common in people over the age of 40. The metabolic syndrome includes: 1) large waist size, 2) high triglycerides, 3) low HDL cholesterol, 4) high blood pressure and 5) high fasting blood sugar. People with the metabolic syndrome have at least three of these five risk factors. Pre-diabetes is considered to be present in those with high fasting blood sugar levels below the diabetes range.

Research has shown that type 2 diabetes and the metabolic syndrome may be prevented or delayed by making lifestyle changes. It is not known what will most help people continue these healthy changes over time. The purpose of this study is to look at ways to help people continue the healthy lifestyle changes they have made while taking part in a diabetes prevention program called Group Lifestyle Balance (GLB).

Interventions

BEHAVIORAL

GLB Traditional Maintenance (TM)

After completion of the GLB 12 core sessions, participants will be randomly assigned to either Group Lifestyle Balance (GLB) program traditional maintenance or GLB Carb-focused maintenance. Participants will attend monthly maintenance sessions to assist them in maintaining the healthy lifestyle they have adopted during the 12 Core sessions. In addition, they will receive information on healthy carbohydrate intake and hunger management.

BEHAVIORAL

GLB-Carb-focused Maintenance (CF)

After completion of the GLB 12 core sessions, participants will be randomly assigned to either Group Lifestyle Balance (GLB) program traditional maintenance or GLB Carb-focused maintenance. GLB-CF participants will attend monthly maintenance sessions to assist them in maintaining the healthy lifestyle they have adopted during the 12 Core sessions. In addition, they will receive information on healthy carbohydrate intake and hunger management.
