Move and Moderate in Balance

Our overall objective is to develop and evaluate an intervention that will maintain or decrease body mass index; specifically, we will recruit and randomize 30 worksites to a two year intervention in which we will:

• Influence the worksite environment, including policies and procedures, by increasing worksite access to healthy foods and physical activity opportunities
• Promote individual behavior change, through increasing awareness of energy balance; building a physical activity intervention that will promote increased levels of energy expenditure through the combination of increased daily physical activity and regular, structured exercise; and building a dietary intervention that will promote decreased calorie intake.

Our primary aim is to:

• Evaluate the effectiveness of the intervention in reducing or maintaining body mass index in a randomized controlled trial of worksites.

Our secondary aims are to:

• Assess changes in worksite environment in access to healthy foods and physical activity opportunities attributable to the intervention
• Assess changes in individual level physical activity and energy intake attributable to the intervention
• Assess the changes in sequalae of weight loss including biomarkers of metabolic effects, and weight loss quality of life and symptom measures; and
• Estimate the cost-effectiveness of the intervention in controlling weight.

Inclusion criteria

• Employees of the enrolled worksite who are 18 years or older and work at the company at least 50% FTE (20 hrs per week)

Exclusion criteria

• Any employees of the enrolled worksite who are interns or seasonal workers or employees who work less than 50% FTE (20 hrs per week)
