目的监测湖北省饮水型氟中毒病区改水工程的运行情况,了解病情变化趋势,评价防控措施效果,为制订防治措施提供依据。方法在全省抽取10个监测县,对每个县(市、区)3个固定监测村的改水工程运行情况、水氟含量、8~12岁儿童氟斑牙、25岁以上成人氟骨症、尿氟等情况开展调查。结果共监测改水工程30个,27个正常运转,水氟含量均值为0.33 mg/L,水氟含量>1.0 mg/L的有2个。儿童氟斑牙患病率8.70%,以极轻度为主,成人氟骨症患病率为2.95%,尿氟均值0.69 mg/L。结论湖北省饮水型氟中毒病情已基本控制,但仍应加强改水工程和病情监测,加强改水工程后期管理和维护。 Objective To monitor the operation of water diversion project in drinking water fluorosis area of ​​Hubei Province, understand the trend of disease condition, evaluate the effect of prevention and control measures, and provide the basis for making prevention and control measures. Methods Ten monitoring counties were selected in our province. The water quality of three fixed monitoring villages in each county (city and district), water fluoride content, dental fluorosis of children aged 8 to 12, fluorosis of adults over 25 years of age Disease, urinary fluoride and other conditions to carry out investigations. Results A total of 30 water improvement projects were monitored and 27 were in normal operation. The average water fluorine content was 0.33 mg / L, and two water fluoride contents> 1.0 mg / L. The prevalence of dental fluorosis in children was 8.70%, with a very mild degree. The prevalence of skeletal fluorosis in adults was 2.95%, and urinary fluoride mean was 0.69 mg / L. Conclusion The drinking water fluorosis in Hubei Province has been basically controlled, but the water diversion project and disease monitoring should be strengthened, and the management and maintenance of the water diversion project should be strengthened.
