Brief Summary:
Obesity is the second leading cause of preventable deaths in the United States and is associated with a wide range of diseases. In people who are obese, weight loss improves blood pressure, dyslipidemia, glycemia, and arthritis symptoms; reduces medication use for several disease processes; increases physical functioning; and enhances health-related quality of life. The current study evaluated a theoretically informed maintenance intervention. If effective, this intervention could reduce the need for future clinic visits to treat obesity and its many associated illnesses.
Detailed Description:
Obesity is the second leading cause of preventable deaths in the United States and is associated with a wide range of diseases. In people who are obese, weight loss improves blood pressure, dyslipidemia, glycemia, and arthritis symptoms; reduces medication use for several disease processes; increases physical functioning; and enhances health-related quality of life. Despite these benefits, most patients who achieve weight loss regain much of this weight within a year, and few effective behavioral weight maintenance interventions have been identified. Thus, there is a dire need for effective interventions that can promote weight loss maintenance. Theoretical and empirical studies indicate that behavior maintenance is a distinct state that involves different psychological processes and behavioral skills than initial behavior change. The few trials that have tested weight loss maintenance interventions have not taken this distinction into account, which may partially explain their modest findings. The current study evaluated the efficacy of a theoretically informed maintenance intervention compared to usual care. If efficacious, this intervention could reduce the need for future clinic visits to treat obesity and its many associated illnesses and could serve as a model for redesigning the MOVE! program. This 3.5-year study involved a two-arm, randomized, controlled trial. During the run-in phase, Veterans with BMI 30 kg/m2 participated in a 4-month, intensive, group-based weight loss program. Participants who lost at least 4 kg by the end of 4 months (n=222) were randomized to receive (a) usual care (n=112) for 56 weeks or (b) a theoretically-informed maintenance intervention (n=110) for 42 weeks months, followed by 14 weeks of no intervention contact to examine sustainability. The maintenance intervention involved in-person group visits that transition to individualized telephone calls, and the frequency of contact with the interventionist gradually tapered over time. Outcomes were assessed at randomization and at weeks 14, 26, 42, and 56 post-randomization. The hypotheses are that the maintenance intervention will result in at least 3.5 kg greater weight loss and greater improvements in caloric intake and physical activity over the study period, and that it will be cost-effective, compared to usual care.
