Health conception and health promotion behaviors were measured in 160 blue collar workers ages 18 to 65, focusing on factors influencing blue collar workers' participation in health promotion programs. Results of Laffrey's Health Conception Scale (LHCS) and Pender's Health Promoting Lifestyle Profile (HPLP) indicated: Health responsibility and interpersonal support were significantly greater for women than for men. Exercise was significantly greater for younger workers than for older workers. Nutrition was significantly greater for older workers than for younger workers. Health conception was significantly greater for younger women and for older men. A significant relationship exists between health conception and health promoting lifestyle. Role and self actualization were significantly greater for older workers than for younger workers. Results suggest gender, age, and concept of health are important when planning health promotion programs at an industrial site.
