In a house-to-house study of 994 urban Zulus the prevalence of hypertension according to WHO criteria was 25% (23% men, 27% women). In a rural Zulu study of 987 the prevalence age corrected to the urban distribution was 9.4% (8.7% men, 10% women). Thus there was a pronounced difference between the prevalence of hypertension in the urban and rural Zulu (p less than 0.0005). There was an earlier onset of hypertension in the urban compared with the rural Zulu. Contrasting biosocial factors in the urban and rural Zulu could explain the differences in prevalence. Our study suggests that hypertension is not a major health problem in rural Zulus. Large-scale case finding and intervention programmes should be confined to the urban black population of South Africa.
在一项对994名城市祖鲁人的逐户研究中,根据世界卫生组织标准,高血压患病率为25%(男性为23%,女性为27%)。在一项对987名农村祖鲁人的研究中,按照城市人口分布校正年龄后的患病率为9.4%(男性为8.7%,女性为10%)。因此,城市和农村祖鲁人高血压患病率存在显著差异(p小于0.0005)。与农村祖鲁人相比,城市祖鲁人高血压发病更早。城市和农村祖鲁人不同的生物社会因素可以解释患病率的差异。我们的研究表明,高血压在农村祖鲁人中并非主要健康问题。大规模病例发现和干预项目应局限于南非城市黑人人口。
