The geographic variation in asthma prevalence and mortality has not been explained adequately. The marked increase in prevalence in communities adopting a more Western lifestyle suggested that some of this variation could be due to changes in sodium intake. The theory was tested using regional data from England and Wales and a strong correlation was found between table salt purchases and asthma mortality in both men and children. Asthma mortality in women was more closely related to prevalence of cigarette smoking. The association was not explained by differences in age, sex or prosperity.
哮喘患病率和死亡率的地区差异尚未得到充分解释。在采用更西方化生活方式的社区中，患病率显著上升，这表明部分差异可能归因于钠摄入量的变化。该理论通过使用来自英格兰和威尔士的区域数据进行了检验，结果发现食盐购买量与男性和儿童的哮喘死亡率之间存在很强的相关性。女性的哮喘死亡率与吸烟率的关系更为密切。这种关联无法用年龄、性别或富裕程度的差异来解释。
