Workplace health promotion initiatives have proliferated, but there are difficulties in recruiting employees of lower socioeconomic status and at higher risk of disease. A survey of health behaviors and attitudes was administered in 20 worksites and the opportunity to attend a health risk assessment promoted. Those more likely to attend were women. those of higher occupational prestige, and those from a non-English-speaking background. After adjustment for these variables, the only health behavior associated with attendance was smoking status. Perceived risk of lung cancer was significant, even after adjustment for smoking status. Stage of readiness to change health behaviors was associated with attendance, with those in the preparation stage being more likely to attend than those in the precontcmplation stage. However. this association was statistically significant only for fruit and vegetable consumption. There was no relation between attendance and support for health promotion, perceived general health, or other perceived risk of disease. These findings suggest that additional risk communication strategies and environmental supports are required to involve those with less prestigious occupations.
