The health-promoting lifestyles of blue-collar, skilled trade, and whi
te-collar workers wee examined. Specific purposes included determining
differences in health-promoting behaviors, especially according to wo
rker category, as well as ethnic identification, age, gender, educatio
n, and marital status. A convenience sample of 638 workers in a midwes
tern automotive components plant completed the Health-Promoting Lifest
yle Profile (HPLP) and demographics questionnaire. In a multivariate a
nalysis of variance (MANOVA) including all demographic variables, sign
ificant differences were found in the mean scores on subscales of the
HPLP by job category (2 subscales), age (3), gender (2), and education
(4). Prior to including education in the MANOVA, significant differen
ces were found by job category on 5 subscales of the HPLP. The effects
of education eliminated the majority of the effects of job category.
