Impact of a workplace holiday weight gain prevention program.

Background: The average worker gains 2-3 lb (0.9-1.4 kg) a year, about half of which is gained during the fall holiday season (Halloween through New Year's).

Aim: The aim of the study was to conduct a pilot test of a weight gain prevention program that was implemented in a workplace setting during the fall holiday season.

Methods: 239 state government employees participated in a weight gain prevention program offered during the fall holiday season. The program was a 10-week, team-based program that consisted of self-monitoring, regular weigh-ins, a team challenge, and organizational support. Weight was measured at baseline, every two weeks during the program, and post-program.

Results: Participants lost a significant amount of weight (from 196.7 lb/89.2 kg to 192.3 lb/87.2 kg) during the program. Positive changes were observed in physical activity and eating behaviors.

Conclusions: This study demonstrated that a weight gain prevention program during a high risk period (fall holiday season) can be effective.
