Drs. Karen Glanz and Kevin Volpp, along with the team at the UPenn PRC, found that participants in all groups lost weight. Incidentally, the financial incentives group lost slightly more weight, but none of the strategies netted significantly greater weight losses than the others. The results from their Healthy Weigh Study are currently published in the September 2021 edition of JAMA Network Open.
In 2015, the University of Pennsylvania Prevention Research Center (UPenn PRC) conducted a study to test strategies to achieve weight loss and maintain weight loss in urban worksites in Philadelphia.
First, researchers collected data on participants who earned daily financial rewards, in addition to those guided on positive changes to their environment.
Second, they compared each strategy, separately and together, to see which one helped the participants achieve weight-loss.
Third, the team compared that data to those who tried to lose weight on their own.
Ultimately, the goal of the study was to manage obesity by improving nutrition and physical activity, in order to reduce the risk of cardiovascular disease and other chronic health conditions.
