[The Brisighella study. III. Hypertension as a risk factor (author's transl)].

The Brisighella Study was performed in a little Emilia-Romagna town with agricultural background to observe coronary heart disease risk factors in this population. At entry, 1972, 1491 males and 1448 females were controlled from the residents of the inner part of the town. The participation response was very high (93%). In this study the hypertension evaluation as risk factor is reported. Measurement of blood pressure has been made in according to W.H.O. criteria. Blood pressure mean values, hypertension prevalence, borderline blood pressure prevalence and hypertension control level have been recorded. The male subjects with hypertension were 33.53%, while female subjects were 33.77%. Borderline blood pressure was higher in males than in females (32.0% vs. 25.7%). Hypertension control level in the examined sample was quite low, however, it appears higher than other reported in similar studies.
