A survey of the place of birth of 200 patients with duodenal ulcer diagnosed by barium meal examination at the Darwin Hospital showed that duodenal ulcer was six times more common in patients born in the United Kingdom and seventeen times more common in patients born in other European countries than in patients born in Australia. However, this much higher incidence in migrants appears to be related to factors other than migration. The survey also shows that relatively acute ulcers are more common in patients born in Australia and relatively chronic ulcers are more common in migrants from the United Kingdom and other Eurpean countries.
