【摘要】 目的 了解农村中小学生体虱感染状况，探讨体虱感染与个人和社会因素的关系。方法 选取蚌埠市农村中小学生758名，肉眼观察学生贴身内衣皱缝处，发现体虱成虫、若虫及活卵者均为感染阳性；对学生的卫生习惯、父母文化程度及职业、家庭居住情况和家庭子女数等进行问卷调查。结果 758名受检学生体虱感染率为9.10%，男生为8.97%，女生为9.39%，差异无统计学意义(P>0.05)；初中生感染率为6.56%，小学生感染率为10.96%，差异有统计学意义(P<0.05)。体虱感染与洗澡、更换内衣、拆洗被褥的频度有密切关系；父母文化程度及职业、居住情况和家庭子女数等对中小学生体虱感染率也有很大的影响(P<0.01)。结论 蚌埠市农村中小学生体虱感染率较高，与不良卫生习惯、父母文化程度及职业、居住情况和家庭子女数等密切相关。
