Do behavioral treatments of obesity last? A five-year follow-up investigation.
Although the long-term maintenance of therapy induced behavior changes and the resulting weight loss represent critical issues in the treatment of obesity, there is a paucity of available data. The present study assessed the durability of treatment induced weight losses 5 years after treatment and the long-term adherence to treatment strategies. Thirty-six of the original 44 subjects who participated in a 10-week behavioral weight control program were interviewed in person (28), by mail (5) or reported their weights by phone (3). Results indicated that most subjects gained back a major portion of the weight they lost during treatment. The average subject had gained 11.94 lb. since treatment termination and was now 1.49 lb. heavier than when he/she entered treatment. Despite the fact that program adherence following the termination of treatment was typically low, both the number of program techniques conscientiously used and the months of conscientious technique use showed significant negative correlations with posttreatment weight gains. Subjects reported that numerous situational, social and emotional factors impacted upon their weight control efforts.
