Continuous Engagement in a Weight-Loss Program Promotes Sustained Significant Weight Loss.
BACKGROUND: Significant weight loss improves health but regain is common. OBJECTIVE: The objective of the study was to determine if 2,346 members of Take Off Pounds Sensibly-a national, low-cost, peer-led weight-loss program-achieved and maintained significant weight loss with 7 consecutive annual renewals. METHODS: This study was a retrospective cohort design. For each renewal, the cumulative change from baseline weight was calculated. Weight change was placed into 1 of 3 categories: significant weight loss, loss ≥ 5%; weight stable, loss of 0 to < 5%; or weight gain, any amount above baseline weight. RESULTS: The cohort included 2,346 individuals. Fifty-one percent (n=740) of participants were in the significant weight-loss category all 7 years; 256 (18%) were in the significant weight-loss category at year 1 but moved into at least 1 other category during years 2 through 6; 359 (25%) were in the weight stable category at year 1; and 98 (7%) were in the weight gain category at year 1. CONCLUSIONS: Over 60% of the population achieved significant weight loss by year 7. Since continuous, long-term engagement in a weight-loss program can lead to significant weight loss, even if significant weight loss is not initially achieved, participation should be encouraged.
