The influence of sex, race and dialect on peptic ulcer and non-ulcer dyspepsia in Singapore.
A consecutive series of 2,277 patients presenting for upper gastrointestinal endoscopy was analysed. The following groups of patients were studied with reference to sex, race and dialect groups: those presenting with dyspepsia but no haemorrhage, those presenting with upper gastrointestinal haemorrhage, those with non-ulcer dyspepsia, gastric ulcer and duodenal ulcer. Males out-numbered females in all diagnostic groups. Male and female Malays were under-represented in all diagnostic groups when compared to the Singapore population. Amongst female Chinese, there was an excess of Cantonese patients and an under-representation of Teochew patients in most diagnostic groups. These dialect differences were not remarkable amongst male Chinese. The possible reasons for these differences and their significance are discussed.
