海口市幽门螺杆菌感染现状与相关危险因素调查

Survey on the current status of Helicobacter pylori infection and related risk factors in Haikou city

目的调查海口市人群幽门螺杆菌(H.pylori)的感染现状,探索其相关危险因素,为本地区H.pylori防治提供参考,进一步为防治胃癌提供理论基础。方法采用整体分层随机抽样的方法,对海口市四个区共1200名居民进行问卷调查和尿素^(14)C呼气试验,计算人群感染率并分析感染相关危险因素。结果海口地区人群总感染率为32.5%,较全国H.pylori感染率低。无进食瓜果蔬菜、无餐前洗手习惯、有消化道症状是H.pylori感染的独立危险因素,而无食用腌制品对预防H.pylori感染具有重要意义。结论海口地区人群H.pylori感染率低于全国平均水平,H.pylori感染与居民的不良生活习惯密切相关。
