Active duodenal ulcer disease was diagnosed in 179 of 748 patients presenting with onset of symptoms of the peptic syndrome in the course of 3 years. The diagnosis was made on the basis of either endoscopy or X-ray. The highest average annual incidence was in kibbutzim and the lowest in moshavim (98.9 and 49.2 new cases/year/100,000, respectively). A peak in the diagnosis of new cases of active duodenal ulcer was demonstrated in November, December and January, compared with an equal distribution among other months. There was a diagnostic peak in the winter, and a seasonal decrease in the fall (56 +/- 4 vs 38 +/- 4, M +/- SE, respectively). These findings were statistically significant when proportions of total visits to the Gastroenterology Clinic were compared (Z = 1.976; p less than 0.05).
在3年期间出现消化综合征症状的748例患者中，有179例被诊断为活动性十二指肠溃疡病。诊断基于内镜检查或X射线。平均年发病率最高的是集体农场，最低的是莫沙夫（分别为每年每10万人中有98.9例和49.2例新病例）。与其他月份分布均匀相比，11月、12月和1月出现了活动性十二指肠溃疡新病例诊断的高峰。冬季有诊断高峰，秋季则呈季节性下降（分别为56±4和38±4，均值±标准误）。当比较胃肠病诊所总就诊比例时，这些发现具有统计学意义（Z = 1.976；p < 0.05）。
