Hypertension screening in a Hungarian town.

In conjunction with a radiological tuberculosis project, a hypertension screening programme was carried out in 1984 on 13,772 people (74% of the eligible adult population) in the Hungarian town of Csongrád. In the younger age groups the blood pressure was found to be higher amongst men, whilst in older groups the women had higher blood pressures. By the WHO criteria, systolic hypertension was detected in one-third of the population and diastolic hypertension in one-sixth. Of the hypertensive patients detected, 34% were previously unaware of their diagnosis. The prevalence of hypertension was elevated particularly amongst obese persons and in the sub-group of physical (blue collar) workers aged over 60 years. There was a significant correlation between alcohol consumption and both systolic and diastolic blood pressures. Hypertension was found in 29.9% of heavy drinkers but in only 20.5% of moderate drinkers or total abstainers.
