Worksite Program to Prevent Weight Gain Among Bus Drivers

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 garages.

It is hypothesized that transit employees in the intervention garages will gain less weight compared to the transit employees in the control garages.

About this study

BACKGROUND:

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.

DESIGN NARRATIVE:

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Employed as a bus driver

Exclusion criteria

  • Not employed as a bus operator at one of the four participating garages

Treatment and study plan

Healthful eating and food choices behavior change programs and changes in worksite food availability and prices

Behavioral

Food choices and eating behavior programs and environmental changes will be implemented for 18 months in intervention garages.

Physical activity

Behavioral

Physical activity programs are offered at the intervention garages for an 18 month period.

Environment

Behavioral

Changes in the food and physical activity environment are made for an 18 month period in intervention garages. These include improving the healthfulness of the foods available in vending machines, and improving the fitness rooms at the garages.
