Death rates from ischaemic heart disease (IHD) in English and Welsh counties are correlated, in both men and women, with the infant mortality rates of those counties when the individuals whose deaths are considered were young, thus confirming previous findings in Norway. In England and Wales, however, there is an equally good correlation between deaths from IHD and infant mortality patterns up to and including that for the same time period as the IHD deaths. The British data provide no grounds for concluding from these relationships that living conditions during early life per se bear a causal relationship to deaths from IHD.
在英格兰和威尔士各郡县，无论男性还是女性，当所考虑的死亡个体尚年轻时，缺血性心脏病（IHD）死亡率与这些郡县的婴儿死亡率相关，这证实了挪威之前的研究结果。然而，在英格兰和威尔士，IHD死亡与婴儿死亡率模式之间也存在同样良好的相关性，且这种相关性一直持续到与IHD死亡相同的时间段。英国的数据无法基于这些关系得出早年生活条件本身与IHD死亡存在因果关系的结论。
