The aim of this study was to compare the impact of two worksite weight management (WM [education] and WM+ [education plus counseling]) programs, on health care utilization and costs. Secondarily, compare the intervention groups to an observational control group of obese workers. Finally, evaluate the impact of actual weight loss on these outcomes.Methods:
Estimate the change in the WM and WM+ intervention groups. Using propensity score adjustment compare the two intervention groups with the observational control group; and compare those who lost weight with those who did not.Results:
No significant differences between the two intervention groups, or between these intervention groups and the observational control group. Those who lost weight reduced their overall health care costs.Conclusions:
To achieve weight loss and associated morbidity reductions, more extensive and intensive interventions, with more attention to motivation and compliance, are required.
