In Central Europe and in South Africa duodenal ulcer disease has been reported to occur twice as often in migrant workers as in the indigenous population. To investigate the reasons for this phenomenon the joint effect of occupation and nationality on the prevalence of gastric and duodenal ulcer was studied in a survey of 73,000 active members of the German workforce. Non-ulcer dyspepsia and gastric, but not duodenal, ulcer were found more frequently in migrant than in indigenous workers. Manual workers were more prone to develop gastric and duodenal ulcer and non-ulcer dyspepsia than sedentary workers. The seemingly increased prevalence of duodenal ulcer in migrant workers observed by other authors may be due to migrant workers being employed predominantly in manual labour which bears a twofold risk of developing duodenal ulcer.
据报道，在中欧和南非，十二指肠溃疡病在 migrant workers 中的发病率是当地居民的两倍。为了调查这一现象的原因，在一项对73000名德国在职员工的调查中，研究了职业和国籍对胃及十二指肠溃疡患病率的联合影响。发现 migrant workers 比本地工人更易患非溃疡性消化不良和胃溃疡，但十二指肠溃疡并非如此。体力劳动者比久坐不动的工人更容易患胃及十二指肠溃疡和非溃疡性消化不良。其他作者观察到的 migrant workers 中十二指肠溃疡患病率看似增加的情况，可能是由于 migrant workers 主要从事体力劳动，而体力劳动患十二指肠溃疡的风险增加了两倍。
