• Conditions: Metabolic Syndrome; Prediabetes
• Interventions: Behavioral: GLB Group; Behavioral: GLB DVD

• Registration Number: NCT00480779
• Lead Sponsor: University of Pittsburgh

Brief Summary

The purpose of this study is to examine different methods of delivering the Group Lifestyle Balance (GLB) intervention (1). The GLB is a 12-week lifestyle change program based on the highly successful lifestyle program that was used in the Diabetes Prevention Program (DPP)(2). A DVD of the Group Lifestyle Program has been developed. Conditions called metabolic syndrome and pre-diabetes increase the risk of diabetes and heart disease. Recent research has shown that type 2 diabetes and metabolic syndrome may be prevented or delayed by making lifestyle changes. A primary care practice will enroll participants who will choose either the GLB-DVD intervention or face-to-face group delivery. Approximately 25 patients will be recruited in each group. It is not known if the GLB intervention delivered via DVD is similarly effective to face-to-face group delivery for people with metabolic syndrome or pre-diabetes. It is hoped that this research study will provide information to help answer that question.

Detailed Description

The Group Lifestyle Balance program is a 12-session lifestyle intervention with the same goals for weight loss and physical activity as the successful Diabetes Prevention Program (DPP) lifestyle intervention and has been evaluated in several settings. The DPSC collaborated with the US Air Force Center of Excellence for Medical Multimedia to create a DVD of the GLB. The GLB-DVD is a series of taped sessions of a staged group following a script that was developed to closely follow the program.

Effectiveness was assessed for the intervention delivered via DVD (GLB-DVD) as well as traditionally in a group setting (GLB-GROUP). For each delivery mode, pre- and 3 month post-intervention measures of weight and the achievement of the program goals were assessed. Secondary outcomes measured included assessment of components of the metabolic syndrome (NCEP ATP III) and HbA1c.

The prevention professionals in the practice and the Diabetes Prevention Support Center (DPSC) who provided support for the GLB-DVD and GLB-GROUP participants were health care professionals trained in delivery of the GLB by the DPSC faculty. Group delivery of the GLB was conducted via weekly in person, meetings delivered over 12-15 weeks. For GLB-DVD delivery, an overview of the GLB-DVD and materials was provided at commencement of the intervention. Participants were instructed to view one session/week. At the end of each month the participant was asked to return their DVD via postage-paid mail to the DPSC and the next sequential DVD was mailed to the participant. During GLB-DVD delivery, the DPSC prevention professional contacted the participant weekly via telephone to review weight, physical activity minutes, and questions/concerns regarding the program. Thus, participants in both GLB-GROUP and GLB-DVD were offered a total of 12 health care professional contacts. Participants in both intervention delivery modes received a GLB workbook, fat and calorie counter, pedometer, and self-monitoring books for tracking food intake and physical activity.

Arm && Interventions

Group	Intervention	Description
GLB Group	GLB Group	The Group Lifestyle Balance program is a direct adaptation of the Diabetes Prevention Program lifestyle intervention. Participants in the study choose traditional GLB face-to-face group delivery or delivery via DVD. Group members met weekly and completed the program over a 12-15 week period. The face-to-face group meetings were led by a trained lifestyle coach, and participants were encouraged to self-monitor their eating and physical activity behaviors. Participants in both intervention delivery modes received a GLB workbook, fat and calorie counter, pedometer, and self-monitoring books for tracking food intake and physical activity.
GLB DVD	GLB DVD	The Group Lifestyle Balance program is a direct adaptation of the Diabetes Prevention Program lifestyle intervention. Participants in the study choose traditional GLB face-to-face group delivery or delivery via DVD. Those who took part via DVD received an overview of the GLB program at the first session, as well as the materials needed for the program. They subsequently watched one session of the program each week, and received a telephone call from a trained lifestyle coach each week to review weight, physical activity minutes and questions/concerns regarding the program. Participants in both intervention delivery modes received a GLB workbook, fat and calorie counter, pedometer, and self-monitoring books for tracking food intake and physical activity.
