目的了解三亚市小学生肠道寄生虫感染情况,为今后更好地开展防治工作提供依据。方法分层整群随机抽取三亚市10所市区小学和4所乡镇小学的2 790名小学生,采用改良加藤法检验粪便中的蛔虫卵、鞭虫卵、钩虫卵。结果三亚市小学生肠道寄生虫总感染率为6.99%,其中蛔虫感染占53.79%,鞭虫感染占42.06%,钩虫感染占4.15%。乡镇小学生感染率明显高于城市小学生(χ2=114.20,P<0.01),城市及乡镇小学生感染率均随年龄的增长而下降(χ2值分别为11.62,36.47,P值均<0.05),乡镇小学男生感染率明显高于女生(χ2=4.23,P<0.05)。结论三亚市乡镇小学生肠道寄生虫感染率仍较高。应加强健康教育,改善卫生条件,整治环境卫生,将防治重点放在农村。
Objective To understand the prevalence of intestinal parasites in Pupils in Sanya and to provide a basis for better prevention and control work in the future. Methods A total of 2 790 primary school students from 10 urban elementary schools and 4 township primary schools in Sanya City were stratified and clustered.

The prevalence of primary schoolchildren in townships was significantly higher than that of urban primary schoolchildren (χ2 = 114.20, P <0.01). The prevalence of primary and secondary school students in cities and townships decreased with age (χ2 = 11.62 and 36.47, P < The infection rate of boys was significantly higher than that of girls (χ2 = 4.23, P <0.05).
