摘要
目的寻找聊城市乙脑暴露、发病的主要危险因素,了解疫苗接种等对人群发病的影响情况,提出我市改进乙脑防制工作的建议。方法采用1:2配比病例对照研究方法。利用描述流行病学方法对资料进行描述性分析,Coxregression模型进行条件Logistic回归分析分析。结果共调查病例31例,对照62例。单因素条件Logistic回归分析差异有统计学意义的因素有:家中是否安装纱门纱窗、家中有无盛放脏水容器、家中或周围有无猪或家禽、是否采取室内灭蚊措施、卫生状况、对预防接种的认识、其他疫苗的接种、居住位置7个因素。多因素条件Logistic回归分析显示,家中或周围有猪或家禽、卫生状况、室内灭蚊3个因素进入模型,差异有统计学意义。结论流行季节注意保持室内外环境卫生、消除蚊虫孳生地、加强个人防护,可有效防止乙脑病例的发生。另外仍应加强乙脑疫苗的免疫接种及查漏补种工作。
