Overweight and Obesity Control at Worksites
Project Period: 9/30/2004 - 6/30/2012
Contact: Dr. Charlotte Pratt
This program supported seven randomized controlled trials at worksites to test
whether worksite environmental and policy interventions in combination with
individual-lifestyle behavior modifications can prevent or control overweight or
obesity in adults. A total of 23,250 employees in seven worksites across the
United States [hospitals, schools (teachers), garages (bus drivers), hotels (hotel
employees), and companies (manufacturing, transportation and personnel
services)] participated in the interventions.
The interventions emphasized combinations of worksite environmental and policy
changes (e.g., fitness equipment, flex time for physical activity, changes in
cafeteria and vending machine food offerings, and employee wellness
counselors), and individual or family approaches (e.g., on-site diet and physical
activity counseling) to obesity prevention. The primary outcome measures were
BMI and change in body weight. Secondary outcome measures included energy
and nutrient intakes, physical activity and fitness, worker productivity, changes in
worksite policies, cost effectiveness, and health care utilization.
