Behavior Modification Comparison Study: Comparison Between the 12-week Group Lifestyle Balance (GLB) Program and the 6-Month Sensible Weigh Program

Abstract

Abstract : Purpose: The objective of this was to determine if participants that completed the Sensible Weigh program would demonstrate larger weight loss due to the longer length of the program and individualized follow-up as compared to shorter Group Life Style Balance (GLB) Program. Other factors that were compared in both programs include: weight loss, activity, and nutrition knowledge improvements. Methods: This was a two-group comparison study, consisting of an anonymous survey that was completed by military beneficiaries participating in the 12-week GLB program or 6-month Sensible Weigh program at the Nutrition Clinic at DGMC. Participants were scheduled into one of the two behavior modification programs based on current clinical protocols, either referred by their primary care provider, or self-referred to the nutritional medicine clinic. Surveys were completed at the first session, and then at the final session of the course. Results: A total of 125 initial surveys were completed, with 66 (52.8%) final surveys returned. Twenty-two of the 50 (44%) Sensible Weigh participants and 44 of the 75 (58.7%) of the GLB participants completed a final survey. Sensible Weigh participants were more likely to be younger, but other demographic measures were similar between groups. Overall, there was no statistically significant difference between programs in self-reported weight loss, exercise, eating habits and knowledge level compared to baseline. However, there was a significant difference in the overall change to the self-reported stage of change (p=0.012), with participants in the Group Lifestyle Balance program more likely to stay the same or increase their change behaviors. Discussion: The results of this study were unable to determine a clear advantage with either lifestyle modification program, although this is likely due to the inherent limitations to the study.
