Abstract
Overweight and obesity are a significant public health concern. Behavioral treatment is considered the first line of intervention for individuals attempting to lose weight. Behavioral weight loss interventions are capable of producing an 8-10% weight loss of initial body weight at six-months. However, not all individuals achieve this magnitude of weight loss. Therefore, the development of alternative approaches to standard behavioral weight loss programs is needed to improve weight loss and weight maintenance efforts. PURPOSE: The purpose of this study was to examine a stand-alone campaign as an alternative strategy for weight management when compared to a standard behavioral weight loss intervention. METHODS: Twenty six sedentary, overweight and obese adult men and women (Age: 43.1 ± 8.9 years; BMI: 33.3 ± 3.7 kg/m²) participated in a behavioral weight loss intervention and were randomized to one of two groups: Standard Behavioral Weight Loss Intervention (SBWL) or Campaign Intervention (CI). Participants in the SBWL attended weekly group meetings, were prescribed 1200-1800 kcal/day, and 200 minutes of moderate intensity physical activity per week. Participants randomized to the CI received the same SBWL components described previously, in addition to an incentive-based point system, a lottery system, and an e-mail based self-monitoring and intervention delivery. Body weight was assessed at week 0 and 12. RESULTS: Both groups achieved significant weight loss from week 0 to week 12 (SBWL group: -5.6 ± 2.9 kg; CI group -3.1 ± 3.4 kg) (p<0.001). There were no significant differences between groups (p=0.603) or a group X time interaction (p=0.052) from baseline. CONCLUSION: The current investigation demonstrated that participants in the CI group achieved modest yet clinically meaningful weight loss at week 12. This is of importance as standard behavioral weight loss interventions can be intensive, costly, and require substantial time commitments from the participants. Therefore, the CI may provide an alternative approach to disseminate an effective behavioral weight loss program to assist a larger proportion of individuals with weight loss and weight maintenance efforts. This may also result in a more positive net impact on the overall health of the population. Future studies should evaluate the effectiveness of the CI long-term to determine whether these findings can be sustained beyond 12 weeks.
