Behavioral weight-loss intervention at the worksite: Feasibility and maintenance

Investigated the feasibility of conducting a behavioral weight-loss program at the worksite and evaluated the effectiveness of a structured-maintenance training protocol. A total of 133 20-60 yr olds in 3 groups completed a 10-wk behavioral treatment program. The treatment program included organizational behavior modification techniques in addition to traditional small-group behavior-therapy procedures for weight control. After treatment, 2 groups received a 4-session structured-maintenance program, and 1 group served as a nonspecific (contact time) control. Follow-ups were conducted at 3 and 6 mo. Although attrition rates were high, the results indicate that the 3 groups lost a significant amount of weight during the 18 wks of treatment plus maintenance training. There were no differential effects of either weight loss or attrition among the 3 groups over the course of treatment or maintenance. Comparison of the structured- vs nonspecific-maintenance training groups at 3- and 6-mo follow-up indicates that the structured training group maintained their weight loss significantly better than the nonspecific control group. Results are interpreted to be consistent with the hypothesis that the skills required to lose weight are different from skills necessary to maintain weight loss over time. Although behavioral weight-loss programs at the worksite appear feasible, high attrition remains a significant problem. Results are discussed in terms of cost-effectiveness of worksite weight-loss intervention and directions for future research. (17 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
