Despite a decline in mortality rates since about 1931 stomach cancer remains a major cause of death in England and Wales. National death rates from 1916 to 1979 are presented by sex, age and 2 broad social-class groups covering manual and non-manual occupations. In both sexes the decline in rates has been most rapid in the young and has slowed progressively with advancing age. The ratio of male/female rates is currently 1.3 at ages 25-34, increases to a peak of 2.7 at ages 55-64 and then declines again but the pattern was different before 1931. Among both men and married women, rates are consistently higher in manual than in non-manual classes, but the difference is greater among men. Rates for men in non-manual occupations, and for both classes of married women, declined markedly between 1931 and 1951, but for male manual workers the decline was relatively slight until after 1951.
尽管自1931年左右以来胃癌死亡率有所下降，但在英格兰和威尔士，胃癌仍是主要死因之一。本文列出了1916年至1979年按性别、年龄以及涵盖体力劳动者和非体力劳动者的两个宽泛社会阶层划分的全国死亡率。在两性中，死亡率下降在年轻人中最为迅速，并随着年龄增长逐渐放缓。男女死亡率之比目前在25 - 34岁时为1.3，在55 - 64岁时升至峰值2.7，然后再次下降，但1931年之前的模式有所不同。在男性和已婚女性中，体力劳动者阶层的死亡率始终高于非体力劳动者阶层，但男性之间的差异更大。非体力职业男性以及两类已婚女性的死亡率在1931年至1951年间显著下降，但男性体力劳动者的死亡率直到1951年之后下降幅度相对较小。
