为了解幽门螺杆菌(Hp) 感染的相关因素，对723 例患者进行Hp 检测。结果显示， Hp 总感染率为 43.2% ，其中男性感染率50.1 %，女性感染率34.9% ，男女之间有显著性差异(P< 0. 05); 各年龄段人群Hp 感染率不同， <20 岁Hp 阳性率最高，≥70 岁Hp 阳性率最低。本研究证实， Hp 感染相关因素包括文化程度、工作压力、饮食习惯、体育锻炼、饮水习惯、卫生习惯和消化系统疾病史。加强Hp 的临床检测与健康教育对Hp 感染的预防与临床诊治均具有重要意义。

In order to investigate the current Helicobacter pylori (Hp) infection and the related factors , a self-designed questionnaire was distributed and collected from 723 patients who received Hp detection. The factors related to Hp infection were analyzed. The total Hp infection rate was 43.2%. A significant difference between male (50. 1 %) and female (34.9 %) ( P< 0.05 ) was observed. The results indicate that the factors related to Hp infection include education, stress, diet, physical exercise, water-drinking habits, health habits and digestive system disease , and consistent with published reports. Therefore , clinical detection of Hp and health education should be strengthened to prevent Hp infection.
