[BDSP. Notice produite par INIST 0HJO2R0x. Diffusion soumise à autorisation]. Objective. Large social inequalities exist in risk of ischaemic heart disease (IHD) in Western populations ; inequalities which are only little accounted for by established risk factors. We wished to find out if some newly identified cardiovascular risk factors in concert with established factors might contribute further to the explanation. Design and Setting. A 6-year follow-up in the Copenhagen Male Study. Subjects. Some 2974 males aged 53-75 years (mean 63) without overt cardiovascular disease were included in the study. Potential confounders included were : alcohol, physical activity, smoking, serum lipids, serum cotinine, serum selenium, lifetime occupational exposure to soldering fumes and organic solvents, body mass index, blood pressure, hypertension, use of sugar in hot beverages, use of diuretics, and Lewis phenotypes. Main Outcome Measures. During the 6-year follow-up period (1985/1986-1991), 184 men (6.2%) had a first IHD event. Compared to higher social classes (classes I, II and III), lower classes (classes IV and V) had a significantly (P<0.05) increased risk of IHD ; age-adjusted relative risk (RR) with 95% confidence limits was 1.44 (1.1-1.9), P=0.02. After multivariate adjustment for age, blood pressure, serum lipids, physical activity, and smoking, the RR dropped to 1.38 (1.0-1.9), P=0.05. (...)
