Background: Hypertension is a major cardiovascular risk factor. The aim of this study was to establish the prevalence of high blood pressure in a European region in Northern Spain (Cantabria), and also levels of detection, treatment, and control.
Methods: On a random multi-stage sample of 1197 individuals aged 18 or over, stratified by sex and age, blood pressure measurements were taken and other general data were collected from 2002 to 2004.
Results: A prevalence of hypertension of 29% was found. The prevalence among males and females was similar, being 29% and 28%, respectively. Sixty five per cent of the hypertensive subjects were aware of their condition, 53% were undergoing treatment, and 22% presented readings below 140/90 mm Hg.
Conclusions: Hypertension constitutes a public health problem in Cantabria, since it affects 1 in 3 of the adult population. Although levels of detection, treatment, and control are superior to those previously described in this region in 1989, the situation could clearly be improved.
