[Prevalence of arterial hypertension, ischemic heart disease and their risk factors in geologists in various regions of the USSR].

The authors presented the results of an epidemiological survey conducted simultaneously for the first time among persons of geological professions in order to reveal the prevalence of arterial hypertension (AH) and coronary heart disease (CHD) with account of labor intensity, climatic and geographic factors. Altogether 1041 men were examined in 4 regions: in Vorkuta (a trans-polar region), Ukhta (a northern region), Chita and the Central region. The highest AH prevalence was detected in Vorkuta (27.4%), the lowest--in the Central region; the highest CHD prevalence was noted in Ukhta, the lowest--in Vorkuta. As for labor intensity, persons whose work was characterized by psychologic stress, suffered from AH and CHD more frequently. Significant differences in the prevalence of these diseases were revealed among managers and employees.
