ABSTRACT
OBJECTIVE: To evaluate the implementation of a multicomponent lifestyle intervention at two different worksites. METHODS: Data on eight process components were collected by means of questionnaires and interviews. Data on the effectiveness were collected using questionnaires. RESULTS: The program was implemented partly as planned, and 84.0% (max 25) and 85.7% (max 14) of all planned interventions were delivered at the university and hospital, respectively. Employees showed high reach (96.6%) and overall participation (75.1%) but moderate overall satisfaction rates (6.8 ± 1.1). Significant intervention effects were found for days of fruit consumption (ß = 0.44 days/week, 95% CI: 0.02 to 0.85) in favor of the intervention group. CONCLUSIONS: The study showed successful reach, dose, and maintenance but moderate fidelity and satisfaction. Mainly relatively simple and easily implemented interventions were chosen, which were effective only in improving employees' days of fruit consumption.
