[The characteristics of arterial hypertension in the population of a preventive medicine service]. / Características de la hipertensión arterial en la población de un servicio de medicina preventiva.

ABSTRACT

Of 2,115 persons who were submitted to a voluntary check-up, we found 10.6% suffering from hypertension and 16.2% with borderline hypertension, the latter group having been followed and the condition subsequently confirmed in 45.9% of the case. The prevalence increases with age. There were no prevailing differences found between rural and city populations. The prevalence is greater in self-employed persons that in salary workers and we would bring to the fore the higher prevalence in housewives (p less than 0.0005). 74.8% of the hypertensive patients knew of their situation but only 15.6% of them showed normal blood pressure at the following-up. Rarely 0.85% had severe hypertension and 3% had moderate hypertension.
