目的掌握新疆生产建设兵团农三师地方性氟中毒的病情现况,为今后地方性氟中毒的防治提供科学依据。方法在14个较大的农牧团场中心小学,采用分层整群抽样方法,调查8～12岁学生氟斑牙患病情况;检测饮水氟含量,8～12岁学生尿氟含量;调查改水情况。结果8～12岁学生氟斑牙总患病率为20.62%,维族患病率明显低于汉族,地方性氟中毒的流行主要集中在1个较小的区域(42团场)并达到轻病区水平;饮水氟浓度为1.11±1.06mg/L;8～12岁学生尿氟含量为1.45±1.02mg/L;改水率达到75%。结论生产建设兵团农三师地方性氟中毒病情在大部分地区基本得到控制,在一个较小局部区域存在轻病区水平的流行,应作为重点加大投入进行改水工作。
Objective To investigate the status of endemic fluorosis in Nansan-hsien Division of Xinjiang Production and Construction Corps and provide a scientific basis for the prevention and treatment of endemic fluorosis in the future. Methods Fourteen large farmer primary school primary schools, stratified cluster sampling method was used to investigate the prevalence of dental fluorosis in children aged 8 ~ 12 years. The fluoride content in drinking water and the urine fluoride content in students aged 8 ~ 12 years were investigated. Change the water situation. Results The total prevalence of dental fluorosis was 20.62% in 8-12-year-old students, and the prevalence of Uighurs was significantly lower than that in Han people. The prevalence of endemic fluorosis was mainly concentrated in a small area (42 groups) The level of fluoride in drinking water was 1.11 ± 1.06 mg / L, while the urinary fluoride in students aged 8-12 years was 1.45 ± 1.02 mg / L. The water-reducing rate reached 75%. Conclusion The incidence of endemic fluorosis in Nansan-Shi-Shi Division of Production and Construction Corps is basically controlled in most areas. In a small area, there is a prevalence of light-ward endemic areas, and more emphasis should be put on water diversion work.
