Blood Pressure in Spain

Abstract

Abstract —Distribution of blood pressure (as per US Joint National Committee VI classification and staging criteria) plus awareness, treatment, and control of hypertension were studied in a representative Spanish population sample of 2021 persons (age range, 35 to 64 years). Pressure was determined in accordance with World Health Organization guidelines. A total of 45.1% of subjects were hypertensive (≥140/≥90 mm Hg or undergoing drug therapy); 12% had isolated systolic hypertension, and 8.7% had isolated diastolic hypertension. Pulse pressure was 48.7 mm Hg. Heart rate was 81.4 bpm in untreated hypertensives and 78.9 bpm in normotensives ( P <0.05). A substantial proportion of the community burden of blood pressure was attributable to stage 1 (28.3% of subjects), the most frequent category of hypertension, and to the high-normal blood pressure group (17% of subjects). A percentage breakdown showed that among hypertensives, 44.5% were aware of their condition; of these, 71.9% were undergoing drug therapy, and of those being treated, only 15.5% were controlled (5% of hypertensives). Not only are these figures consistent with the fact that Spain has a higher cerebrovascular mortality than other countries such as the United States, but they represent a great potential for improvement, particularly among those groups registering relatively worse data (younger men, rural residents, and unskilled professionals). A decrease of only 1 to 4 mm Hg in average blood pressure could reduce the prevalence of hypertension in Spain by 12.4% to 15.4%.
