目标.本研究旨在描述血压分布、高血压患病率。和相关的危险因素：在西非起源的七个人群中。在高度标准化的合作协议的基础上，对西非（尼日利亚和喀麦隆）、加勒比海地区（牙买加、圣卢西亚、巴巴多斯）和美国（大都会芝加哥、伊利诺伊州）的高血压发病率进行了比较。在研究人员接受了调查方法的集中培训后，在7个地点对800至2500名25岁以上的成年人进行了调查。得到总共10014个样本。观察到高血压患病率的一致梯度，从西非的16%上升到加勒比的26%和美国的33%。25至34岁人群的平均血压相似，而美国高血压患病率随年龄增长的幅度是非洲的两倍。环境因素，最明显的是肥胖和钠钾摄入量，在不同地区的患病率有一致的变化。研究结果表明，在这些人群中，社会条件在高血压风险演变中起决定性作用。
Objectives. This study was undertaken to describe the distribution of blood pressures, hypertension prevalence. and associated risk factors: among seven populations of West African origin.Methods. The rates of hypertension in West Africa (Nigeria and Cameroon), the Caribbean (Jamaica, St. Lucia, Barbados), and the United States (metropolitan Chicago, Illinois) were compared on the basis of a highly standardized collaborative protocol. After researchers were given central training in survey methods, population-based samples of 800 to 2500 adults over the age of 25 were examined in seven sites. yielding a total sample of 10 014.Results. A consistent gradient of hypertension prevalence was observed, rising from 16% in West Africa to 26% in the Caribbean and 33% in the United States. Mean blood pressures were similar among persons aged 25 to 34, while the increase in hypertension prevalence with age was twice as steep in the United States as in Africa. Environmental factors, most notably obesity and the intake of sodium and potassium, varied consistently with disease prevalence across regions.Conclusion. The findings demonstrate the determining role of social conditions in the evolution of hypertension risk in these populations.
