The dissemination of the standard risk factors for the cardiovascular system--smoking, family history of hypertension and abnormal weight in telephone operators is evaluated by including one, two or three of these factors (p = 260). A high relative part is taken by persons in the presence of the evaluated factors--75.8%, as the most highly spread is the factor "smoking" (58.8%) and smoking and family predisposition (15.4"). In persons with high blood pressure the dissemination of one or two of the examined risk factors is nearly the same, with heightened presence of "smoking and abnormal weight". In spite of the lack correlation between the studied risk factors and the arterial blood pressure, their dissemination on a large scale as well as the specific character of the telephone operators work certify a heightened risk of diseases of the cardiovascular system and the necessity of special attention to these endangered people.
