An epidemiologic study was carried out in June 1986 among 1702 industrial workers from the machine-building and metal-manufacturing industry--956 men and 746 women. 57.9% of the workers were in the 30-39 and 40-49 age groups. Arterial hypertension was found in 16.6% of the examined and borderline hypertension was found in 12.9%. With advancing age the hypertension frequency increases. Men suffer more frequently (18.4%) than women (14.2%). In younger age this difference is statistically significant. A relation was established between hypertension and obesity in both sexes. The characteristics of the hypertension structure and the relation of borderline hypertension with age, sex and body mass are discussed.
