Data on the prevalence of arterial hypertension (AH) among female workers of a large Vladivostok ship-repair plant, between 20 and 54 years of age, are presented. AH was detected in 17.5% of the screened women. The results of follow-up screening tests, performed 3 years later, are reviewed. Marginal arterial hypertension is shown to be the principal source of AH. Aggravated cardiovascular heredity also contributes to AH. Women showed great interest in participating in preventive and therapeutic programs at the medical division of an industrial enterprise.
