Workplace-Sponsored Program to Reduce Obesity

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to design a comprehensive nutrition and physical activity strategy to gain a broad understanding of the social and cultural role of food and physical activity among workers. Perspectives on innovative interventions that are socially feasible and culturally acceptable will also be obtained. Health lifestyle promotion interventions addressing portion control, healthy nutrition, and increasing physical activity will be tested.

Detailed Description
-----------------
BACKGROUND: Broad, population-based approaches are needed to stop or reverse the rise in obesity prevalence. According to the World Health Organization, obesity prevention can be achieved by promoting a healthy diet and a physically active lifestyle. A partnership with the Eastman Kodak Company has been developed to test a worksite intervention for obesity prevention in Rochester, New York. DESIGN NARRATIVE: The overall goal of this study is to design a comprehensive nutrition and physical activity strategy based on participatory research to promote a healthy lifestyle and to stop the shift of the population body mass index (BMI) curve to the right. Six pairs of worksites will be randomized to either an intervention or control group. Two cross-sectional samples of employees within each worksite will be measured at baseline and at the end of the intervention.
