Epidemiologic studies demonstrated an excess risk of ischemic heart disease (IHD) among individuals who simultaneously exhibit hypertension and elevated atherogenic lipids (coronary high risk (CHR)-status). Yet, relatively little is known about factors which contribute to the development of CHR-status during early and middle adulthood. The present study explores the role of selected biobehavioral and psychosocial factors in explaining CHR-status using data from a prospective 6.5 years investigation of a cohort of 416 middle-aged (40.8 +/- 9.6 years) male blue-collar workers. Multivariate logistic regression analysis shows that overweight (odds ratio (o.r.) 4.14), smoking (o.r. 2.19), low promotion prospects at work (o.r. 2.71), competitiveness at work (o.r. 2.79) and feelings of sustained anger (o.r. 5.41) independently contribute to the explanation of CHR-status. Furthermore, the operational definition of CHR-status is validated by estimating its power in predicting IHD incidence in the study cohort. In conclusion, co-manifestation of hypertension and elevated lipids is more likely to exist among those blue-collar men who exhibit distinct work-related characteristics in addition to established biobehavioral risks such as overweight and smoking. In view of the high prevalence of CHR-status and of IHD among men in the lower socio-economic strata this finding is also of interest for health policy.
