Nine worksites were designated treatment sites and three control. At treatment sites, employees were provided enhanced access to healthy foods in vending machines and cafeterias, greater access to physical activity through walking trails and pedometer programs, dissemination of multiple health education materials, leadership training, physical activity and weight management programs, health assessments and individual consultations, and online behavior change programs. Researchers found that after one year, employees who participated in the environmental weight management interventions significantly reduced their blood pressure risk and maintained a steady weight when compared to employees at control sites.
