To evaluate the prevalence of Helicobacter pylori (H. pylori) among Saudi medical students.
Volunteer medical students were randomly selected in the College of Medicine, King Saud University, Riyadh, Saudi Arabia from January 2005 to May 2005. A urea breath test (UBT) was performed for each medical student. Important demographic data was recorded. Each student had to answer a questionnaire on upper gastrointestinal (UGI) symptoms before the UBT.
A total of 120 students were recruited (73 males [61%] and 47 females [39%]) with a mean age of 22.2 years (age varied from 18 to 28 years). The prevalence of H. pylori was surprisingly low at 35%, compared to a previously reported high prevalence among the Saudi population (80%). Thirty-one percent of medical students reported >or= 1 UGI symptom with no significant differences between the positive and negative UBT results. Although there was a trend, there was no significant prevalence difference between the preclinical and the clinical group of students.
We found a low prevalence of H. pylori in our young university medical student's population. The low prevalence of H. pylori in this young population may have important clinical and economic implications.
评估沙特医学生中幽门螺杆菌（H. pylori）的感染率。
2005年1月至2005年5月期间，在沙特阿拉伯利雅得国王沙特大学医学院随机挑选了志愿医学生。对每位医学生进行了尿素呼气试验（UBT）。记录了重要的人口统计学数据。每位学生在进行UBT之前必须回答一份关于上消化道（UGI）症状的问卷。
共招募了120名学生（73名男性[61%]和47名女性[39%]），平均年龄为22.2岁（年龄范围为18至28岁）。与之前报道的沙特人群高感染率（80%）相比，H. pylori的感染率低得出奇，为35%。31%的医学生报告有≥1种UGI症状，UBT阳性和阴性结果之间无显著差异。尽管存在一种趋势，但临床前和临床学生组之间的感染率无显著差异。
我们发现年轻的大学医学生群体中H. pylori感染率较低。这一年轻人群中H. pylori的低感染率可能具有重要的临床和经济意义。
