About the Study
Twenty-eight automobile industry worksites were randomized to receive the Next Step program or a company-sponsored screening program. Participants in the Next Step program received an enhanced screening program and a diet-change program. To promote screening, employees received a personalized educational booklet. A follow-up companion telephone call was made to review the booklet and screening schedule, and highlight cancer risks and facts. To promote healthier eating, five nutrition education classes were offered during work time and employees were also mailed self-help materials. In the second year, employees received personalized feedback to encourage maintenance of first-year gains. The feedback consisted of a graphic comparison of the employee's diet to the USDA Food Guide Pyramid and motivational messages based on the employee's responses to a food frequency questionnaire. In addition, worksite cafeterias displayed posters and brochures relaying simple messages about low fat, high-fiber eating, and a quarterly newsletter was also mailed to employees' homes to promote and reinforce intervention strategies. Surveys to measure changes in dietary outcome and screening behavior were mailed at the end of the first and second year of the study.
- At Year 1 of the program, Next Step participants decreased their energy from fat, and increased their servings of fruits and vegetables.
- At Years 1 and 2, Next Step participants increased their fiber consumption compared to control participants.
- At Year 2, Next Step participants had modest, but higher screening compliance (receiving all recommended examinations) and coverage (receiving at least one recommended examination) compared to participants in the control group.
