The purpose of this study is to implement and evaluate a two-year multi-component
environmental intervention to prevent weight gain among city bus drivers at four bus
It is hypothesized that transit employees in the intervention garages will gain less weight
compared to the transit employees in the control garages.
Environmental influences that support less healthful food choices and sedentary behaviors
have contributed to the epidemic increase in overweight and obesity among U.S. adults.
Worksite settings are an effective channel through which to reach adults with interventions
designed to prevent excess weight gain and obesity.
This study will implement and evaluate a multi-component environmental intervention to
prevent excess weight gain among 1200 bus drivers working in four garages in a major
metropolitan area. Four garages will be randomized to the intervention or control group for
a two-year period. The environmental interventions are based on a social ecological
framework and target four worksite environmental areas: 1) food availability and incentives;
2) physical activity opportunities and incentives; 3) the social environment; and 4)
media/promotion related to health food choices, physical activity, and body weight.
- Employed as a bus driver
- Not employed as a bus operator at one of the four participating garages
