||Shift work, confounding and death from ischaemic heart disease
||Mar. 2008, Vol.65, No.3, p.158-163. 19 ref.
||The objective of this study was to investigate the relation between shift work and death from ischaemic heart disease (IHD) and evidence for confounding by social class and healthy shift worker effects. The cases were 635 members of a cohort of industrial workers who died of ischaemic heart disease during 1950-98. Referents were matched on age and year of starting work at the site and were alive at time of case's death. Shift work status was determined from historical personnel records and pre-employment weight, height, blood pressure and smoking from medical records. Social class at first employment was inferred from job titles. Conditional logistic regression analysis was used to estimate ORs. 55% of subjects had worked as shift workers. Shift workers were more likely than day workers to belong to social class IV or V. No excess risk of death from IHD for shift workers was found. The potential for confounding by social class in this relatively homogeneous cohort underlines the need to consider such confounding in more heterogeneous populations.
