[Gastric diseases in foreign workers in the German Federal Republic (author's transl)].

Gastric biopsies from foreign workers were compared with those from German patients of the same age group. With reference to population statistics investigations showed that a far higher percentage of foreign workers are gastric patients than are Germans of the same age. Chronic atrophic antral gastritis occurs in foreigners twice as often as in a comparative group of Germans. 77% of the duodenal ulcers and 88% of the gastric ulcers are found in the group of foreign workers examined aged from 21 to 40 years. The German patients, on the other hand, show normal gastric mucosa with more than chance frequency compared with foreign workers of corresponding age and sex.
