[Prevalence of main risk factors for ischemic heart disease in a cohort of 41,972 participants from Southern Poland Epidemiological Survey].

Southern Poland Epidemiological Survey (SPES) was carried out in 1997 in the former Katowice and Bielsko voivodeships with the aim of cardiovascular disease prevention. One of the objectives of SPES was to establish the prevalence of the risk factors for atherosclerosis. This paper describes a group of 41,927 adults (24,985 women and 16,942 men) with no signs and symptoms of ischaemic heart disease who participated in the study, comprising 83.7% of all the examined cohort. Hypercholesterolemia and hypertension, present in 55.8% and 45.3% of subjects respectively, were found to be the main risk factors in both men and women. Hypercholesterolemia was more prevalent in older age groups. 33.7% of women and 46.3% of men were overweight, 23.9% and 17% respectively were obese. 22.4% of women and 31.9% of men were active smokers. Smoking was more common in younger age groups. 25.3% of women and 21.5% of men had a positive family history for ischaemic heart disease before the age of 60 years. High prevalence of classical risk factors in the examined group indicates that population strategy should be introduced in primary prevention of cardiovascular disease in this area.
