【摘要】 目的了解云南那邦口岸中缅双边贾第虫感染危险因素。方法 2008年整群随机抽取中国盈江县那邦镇和缅甸拉咱市边境自然村,对调查点内居住时间>1年的边民进行流行病学问卷调查及新鲜粪便碘液涂片镜检,采用logistic回归方法对数据进行统计分析。结果共调查6个自然村903人,平均年龄为(22.81±18.82)岁;总贾第虫感染率为13.51%,其中调查2个中国自然村286人,感染率为2.10%;调查4个缅甸自然村617人,感染率为18.80%;单因素分析结果表明,国籍、年龄、民族、用手抓饭、喝生水、饮用水源、近1月内腹泻、使用厕所类型和粪便带粘液为可能的危险因素;多因素分析结果表明,国籍、年龄、民族、喝生水和粪便带粘液为主要危险因素。结论直接饮用被粪便污染的水源是缅甸边民贾第虫流行的主要原因。更多还原
