Pathways to Employee Outcomes in a Workplace Health Promotion Program.

PURPOSE

This study examined the relationship between employee outcomes and employer implementation of evidence-based interventions (EBIs) for chronic disease prevention.

DESIGN

Cross-sectional samples collected at 3 time points in a cluster-randomized, controlled trial of a workplace health promotion program to promote 12 EBIs.

SETTING

King County, WA.

SAMPLE

Employees of 63 small, low-wage workplaces.

MEASURES

Employer EBI implementation; 3 types of employee outcomes: perceived implementation of EBIs; perceived employer support for health; and health-related behaviors, perceived stress, depression risk, and presenteeism.

ANALYSIS

Intent-to-treat and correlation analyses using generalized estimating equations. We tested bivariate associations along potential paths from EBI implementation, through perceived EBI implementation and perceived support for health, to several employee health-related outcomes.

RESULTS

The intent-to-treat analysis found similar employee health-related behaviors in intervention and control workplaces at 15 and 24 months. Workplaces implemented varying combinations of EBIs, however, and bivariate associations were significant for 4 of the 6 indicators of physical activity and healthy eating, as well as perceived stress, depression risk, and presenteeism. We did not find significant positive associations for cancer screening and tobacco cessation.

CONCLUSION

Our findings support broader dissemination of EBIs for physical activity and healthy eating, as well as more focus on improving employer support for employee health. They also suggest we need better interventions for cancer screening and tobacco cessation.
