3368例武汉市儿童幽门螺杆菌感染的临床分析

目的了解武汉市有消化道症状的儿童幽门螺杆菌感染状况、分布特征及影响因素。方法选取我院及武汉市医院2010年8月～2011年7月3 368例有消化道症状的儿童,以性别和年龄进行分组,通过14 C-尿素呼气试验检测幽门螺杆菌感染情况,并对其结果进行统计学分析,同时对这些儿童的生活方式进行问卷调查分析。结果 3 368例受检儿童H.pylori总感染率为29.2%,其中男女儿童H.pylori感染阳性率分别为29.2%和29.1%,男女儿童H.pylori感染阳性率差异无统计学意义(P>0.05);学龄前、学龄期及青春期儿童H.pylori感染阳性率分别为27.1%、28.7%和39.1%,学龄前期与学龄期H.pylori感染阳性率差异无统计学意义(P>0.05),学龄前期、学龄期与青春期H.pylori感染阳性率差异有统计学意义(P<0.01);年龄与H.pylori感染阳性率相关(P=0.001);同年龄组男女儿童H.pylori感染阳性率差异无统计学意义(P>0.05);父母幽门螺杆菌阳性患儿幽门螺杆菌阳性率57.5%。结论武汉市有消化道症状的儿童幽门螺杆菌感染率高,随年龄增长感染率递增,但与性别无关,父母幽门螺杆菌阳性患儿幽门螺杆菌阳性率高,年龄、家庭聚集性、父母H.pylori感染与儿童H.pylori感染相关。
