The prevalence of hypertension in the Indian population of Durban

Abstract

In a random house-to-house study of 1 000 Indians the prevalence of essential hypertension according to the World Health Organization (WHO) criteria was 19% (females 22%; males 15%). The study revealed that the prevalence of hypertension was higher than in published data from India. Ethnicity in our study caused a significant variation in prevalence. Prevalence was lower than in our urban Zulu study. Blood pressure rose with age, but there was a greater rise in systolic than in diastolic blood pressure. Prevalence in males and females under 40 years were equal. There was an association between hypertension and diabetes mellitus. More effective screening and therapeutic programmes should be initiated in the Indian population because of the high prevalence of hypertension which may lead to complications if untreated, and because 58% of the hypertensive subjects were untreated or had discontinued therapy.
