Southern Africa presents some fine opportunities to examine the relation of lifestyle to chronic disease. A cross-cultural comparison of disease is the only feasible way to study many of the chronic diseases. Biomedical scientists have an obligation to undertake this. If they do not, there is the dreadful expectation that the rising cultures will soon suffer the same diseases which the members of the highest socio-economic classes must now endure.
南部非洲为研究生活方式与慢性病之间的关系提供了一些很好的机会。对疾病进行跨文化比较是研究许多慢性病的唯一可行方法。生物医学科学家有义务承担这项工作。如果他们不这样做，那么可怕的预期是，新兴文化群体很快就会患上那些目前社会经济地位最高阶层的成员必须忍受的同样疾病。
