In order to study the epidemiology of hypertension in the elderly and its relationship to other disease situations, a study was performed on 815 institutionalized elderly people indicating a statistically significant decrease of both systolic and diastolic blood pressure with age. There is a difference between the population originating in Europe and America and those from Asia and Africa; in the latter group the blood pressure values were significantly higher, specially in females. The prevalence of hypertension as a disease does not differ between younger and older age groups. The lower prevalence in the population studied (28.1%) when compared to data in the literature which indicates prevalence of about 40%, might be due to the fact that the institution population live under sheltered conditions and close medical follow up. In conclusion hypertension in the elderly serves as a major risk factor for several disease situations thus leading to a better survival for those with lower values of blood pressure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
