The effects of a health promotion-health protection intervention on behavior change : The wellworks study.
This study assessed the effects of a 2-year integrated health promotion-health protection work-site intervention on changes in dietary habits and cigarette smoking.
A randomized, controlled intervention study used the work site as the unit of intervention and analysis ; it included 24 predominantly manufacturing work sites in Massachusetts (250-2500 workers per site).
Behaviors were assessed in self-administered surveys (n=2386 ; completion rates=61% at baseline, 62% at final).
Three key intervention elements targeted health behavior change : (1) joint worker-management participation in program planning and implementation, (2) consultation with management on work-site environmental changes, and (3) health education programs.
Significant differences between intervention and control work sites included reductions in the percentafes of calories consumed as fat (2.3% vs 1.5% kcal) and increases in servings of fruit and vegetables (10% vs 4% increase).
The intervention had a significant effect on fiber consumption among skilled and unskilled laborers.
No significant effects were observed for smoking cessation.
Although the size of the effects of this intervention are modest, on a populationwide basis effects of this size could have a large impact on cancer-related and coronary heart disease end points.
