The incidence of peptic ulceration in some african tribal groups

Abstract
1. 1) The incidence of gastric and duodenal ulcer in three groups of people of diverse origins, living in the neighbourhood of Kampala, Uganda, was assessed by means of a consecutive series of postmortem examinations. 2. 2) For male subjects, the gross incidence of peptic ulcer in the local people was 13.68 per cent., in Nilotic immigrants 5.4 per cent., and in immigrants from the south-west (especially Ruanda) 20.6 per cent. 3. 3) The generally high incidence, 15.3 per cent. in men and 4.65 per cent. in women, is in contradiction of previous reports from tropical Africa, especially autopsy reports. 4. 4) It is suggested that the causes of peptic ulcer are abundantly operative in tropical Africa, but that the conditions in which the disease may be brought to notice are rarely fulfilled.
