生长迟缓儿童幽门螺杆菌感染情况调查

目的：调查生长迟缓儿童幽门螺杆菌感染情况。方法对30例生长迟缓儿童和32例健康对照组儿童分别进行14 C呼气试验，了解幽门螺杆菌感染情况，并对其饮食情况进行调查问卷分析。结果30例生长迟缓儿童中幽门螺杆菌感染率为46．67％（14/30），健康对照组儿童幽门螺杆菌感染率为18．75％（6/32），两组幽门螺杆菌感染率差异有统计学意义（P＜0．05）。生长迟缓组儿童在膳食结构上谷类、瘦肉类和蛋类摄入较健康对照组少，在饮食行为方面，吃饭时间超过30 min和吃饭时看电视两组差异有统计学意义（P＜0．05）。结论幽门螺杆菌感染可能是影响儿童生长的环境因素之一。
