Weight Status During and After a 12-Week Weight Loss Program at the Worksite

Recent reports indicate that 65% of the adult population is overweight (BMI ³ 25) and 31% is obese (BMI ³ 30). The potential benefits of weight loss are of great importance to public health. Many studies indicate that individuals who lose weight in short-term weight loss programs regain weight at the end of such interventions. The purpose of this study was to examine weight change both during and after a 12-week incentive-driven weight loss program. This incentive-driven worksite program called “Waist Away” was implemented at a small manufacturing company with 70 employees. The 12 week program involved participants forming two to four person teams. Each participant was required to pay a $5 registration fee. The team that lost the greatest percentage of their combined total body weight at the end of the 12 weeks received $200. This incentive was all of the registration money totaling $140 plus $60 provided by the Human Resources Department. Participants attended four 30 minute seminars that focused on the importance of physical activity, fluid intake, consumption of complex carbohydrates, and fat reduction during the program. Participants were weighed at the start of the program (PRE), at the conclusion of the program (POST) and 12 weeks after the conclusion of the program (POST-POST). Participants were never informed that the POST-POST data collection would take place until the day of reweighing. This was to ensure that this reweighing would not influence motivation for weight loss. A total of 20 employees (19 females, 1 male) out of a workforce of 70 completed the program. A one-way repeated measures ANOVA was calculated comparing the weight of participants: PRE, POST, and POST-POST. A significant effect was found (F(2,38) = 22.36, p < .001). Follow up protected t-tests revealed that weights decreased significantly from PRE (87.06 ± 23.17 kg) to POST (83.98 ± 23.32 kg) and again to POST-POST (82.91 ± 23.76 kg). In a similar manner BMI decreased significantly from PRE (31.53 ± 6.73 kg/m2) to POST (30.41 ± 6.90 kg/m2) and again to POST-POST (30.01 ± 7.08 kg/m2). Mean weight loss was from PRE to POST was 3.08 ± 3.10 kg and 1.07 ± 1.88 kg from POST to POST-POST. These results indicate that the use of monetary incentives may increase motivation and help employees lose weight over a 12 week period. Additionally, unlike many studies, this research shows that participants will not always gain weight following a short-term intervention.
