Demographic data from a hospital case series of endoscopically-diagnosed benign peptic ulcer in southern Israel, 1989-1990.
BACKGROUND
A knowledge of the clinical and epidemiological features of duodenal and gastric ulcer is of importance to clinicians and other health care providers. These aspects of ulcer disease have not been studied previously in the Negev region of southern Israel, which is home to 300,000 Jews and 60,000 Bedouin Arabs.


METHODS
Clinical, demographic and risk factors were analyzed in a case series of benign duodenal and gastric ulcers (first or recurrent attack) diagnosed at endoscopy at the Soroka Medical Center in the years 1989-1990.


RESULTS
There were 336 cases of duodenal ulcer (321 cases in Jews, 15 in Bedouins) and 79 cases of gastric ulcer (all in Jews). The annual rate of endoscopically-detected duodenal ulcer was 54/10(5) in Jews and 13/10(5) in Bedouins. The annual ratio of endoscopically-detected gastric ulcer in Jews was 13/10(5). The ratio of male to female patients was 2.7 for duodenal ulcer in Jews and Bedouins, and 1.9 for gastric ulcer in Jews. The mean age +/- standard deviation at diagnosis was 48 +/- 17 years for duodenal ulcer and 63 +/- 15 years for gastric ulcer (p < 0.001). Duodenal ulcer was significantly commoner than gastric ulcer at all ages, but the ratio DU:GU decreased with increasing age, so that by age 48 years, 20% of all endoscopically-diagnosed ulcers were GU. Of several risk factors examined, smoking was associated with duodenal ulcer (p < 0.05) but not gastric ulcer. Occupation was not a risk factor. Duodenal ulcer was 1.3 times more frequent in winter than summer.


CONCLUSIONS
Endoscopically-diagnosed duodenal and gastric ulcer is commoner in Jews than Bedouins and in men than women. Duodenal ulcer is commoner than gastric ulcer and presents at a younger age. Smoking is a risk factor for duodenal ulcer, and European and American ethnic origin is a risk factor for duodenal and gastric ulcers. Bleeding is associated with one-third of endoscopically-diagnosed ulcers in this institution.
