Abstract
Individuals who participate in weight loss programs often fail to make permanent lifestyle changes and therefore experience weight regain when the program is over. PURPOSE: We compared the effects of two home-based behavioral interventions designed to foster more permanent changes in diet and exercise. METHODS: 105 men and women (age = 51.1 + 8.1) participated in a 6 month clinic-based weight management program consisting of moderate intensity exercise, nutrition education and a behavior change intervention based on the Transtheoretical Model (TTM). Following the clinical program, subjects were randomized into two groups: the individualized group received two tailored expert-system reports (stage of change, TTM process use) and the comparison group received non-tailored action-oriented materials on diet and exercise at the same time points. RESULTS:Table: No Caption Available*denotes significant differences from baseline (p < 0.05) There were no differences between groups for any measured variable. CONCLUSION: Both interventions were effective in maintaining a significant weight loss and changes in diet and exercise behaviors at one year. Because most weight loss programs last for less than 6 months and end abruptly, the addition of home-based maintenance programs may help promote more permanent lifestyle changes.
