The prevalence of hypertension in blacks is higher than that of whites by all demographic variables. This might lead to the conclusion that there is a genetic basis for the disease. Prevalence differences among black populations in different geographic areas, however, point to environmental factors. An ecological hypothesis to explain the intake and retention of salt and the response to environmental stress as possible reasons for the interracial and intraracial prevalence differences are presented. Physicians may find this ecological approach of use in improving treatment of black hypertensive patients.
在所有人口统计学变量方面，黑人高血压的患病率均高于白人。这可能会得出该疾病存在遗传基础的结论。然而，不同地理区域黑人人群之间的患病率差异表明存在环境因素。本文提出了一种生态学假说，将盐的摄入与潴留以及对环境应激的反应作为种族间和种族内患病率差异的可能原因。医生们可能会发现这种生态学方法有助于改善对黑人高血压患者的治疗。
