摘　　要：目的对云南省德宏州陇川县拉影镇与芒市遮放镇少数民族儿童肠道寄生虫感染近况及儿童的健康状况进行调查,为该地区儿童肠道寄生虫病的普查防治工作及采用规范药物进行驱虫等防治手段提供参考。方法在拉影镇和遮放镇少数民族聚居地区分别选择一个学校的儿童,收集粪便,一份标本分别采用饱和盐水浮聚法和离心沉淀法两种浓集法检查肠道寄生虫卵。结果共检查粪便199份,肠道寄生虫感染36例,阳性率为18.09%。其中拉影镇感染率为16.16%(16/99);遮放镇感染率为20.00%(20/100),差异无统计学意义(P=0.243)。共检出3种肠道寄生虫卵:钩虫感染率为5.53%(11/199);蛔虫感染率为12.06%(24/199);带绦虫感染率为3.52%(7/199),蛔虫感染率显著高于带绦虫,差异有统计学意义(P=0.031)。调查发现,随着母亲受教育程度的增高,儿童肠道寄生虫感染率呈下降趋势。结论两地区儿童肠道寄生虫感染率无明显差异,其中蛔虫感染率最高。有计划地在这些地区和人群中开展卫生宣教和药物驱虫,是有效降低感染率的重要措施。Objective To survey the intestinal parasitic infection of children living at the minority area of Dehong state, Yunnan province. Methods Local people of Dehong Longchuan and Mangshi county, and minorities areas were involved in the investigation.Questioners and faecal samples were collected from each individual.The samples were stored in potassium dichromate （2% ,w/v） at room temperature. Stools were processed concentrated by centrifugal precipitation and saturated brine flotation methods. Eggs were examined under microscope. Results 199 samples were examined.36 samples （18.09%） were positive. The rate of infection in the Laying town was 16.16%（16/99）. The rate of infection in Zhefang town was 20.00% （20/100）. The rate of infection by hookworm, roundworm and tapeworm was 5.53% （11/ 199）, 12.06% （24/199） and 3.52% （7/199）, respectively. In this survey, it showed that if mother was high educated, their children＇s intestinal parasite infection rate tends to decline. Conclusions Infection rates were not significantly different in the two different areas. Hookworm infection rate of different nationalities reveals significant differences. Improving the health education and promotion of anti-helmintic work are strategies to reduce parasitic infection.
