[目的]了解周口市降氟改水措施落实情况,动态观察降氟改水措施后的预防效果,为指导以后地方性氟中毒防治工作提供科学依据。[方法]按照国家《地方病防治项目技术方案》进行,水氟测定用离子选择电极法(GB/T8538-1995),氟斑牙诊断用Dean法,成人氟骨症检查执行国家标准。已改水自然村,对降氟改水工程使用、管理和报废情况进行调查登记。[结果]经过3年共调查13905个自然村,水氟含量超标6125个自然村(占44.05%),病区人口数为3650773人,氟斑牙患病人数达915516人,患病率为25.07%,氟骨症患病人数达23806人,患病率为0.65%。[结论]周口市地方性氟中毒防治形势不容乐观,病区范围进一步扩大,危害仍十分严重。降氟改水是控制地方性氟中毒的主要方法,降氟改水设施能否正常使用,关键是落实建、管、用三环节责任制。
[Objective] To understand the implementation of the fluorine-reducing water-reforming measures in Zhoukou City and to observe the preventive effect after the water-reducing and water-reforming measures to provide scientific basis for the prevention and control of endemic fluorosis. [Method] According to the national program of endemic disease prevention and control project, the national standard was checked by ion selective electrode method (GB / T8538-1995) for determination of fluoride in water, Dean method for diagnosis of dental fluorosis and adult fluorosis. Has been diverted to natural villages, the project to reduce fluoride use, management and retirement registration investigation. [Results] After 3 years of investigation, a total of 13,905 natural villages were surveyed. The water fluoride content exceeded the standard of 6,125 villages (accounting for 44.05%), the ward population was 3650773, the number of dental fluorosis was 915516, the prevalence was 25.07% Skeletal disorders amount to 23806 people, the prevalence was 0.65%. [Conclusion] The situation of prevention and treatment of endemic fluorosis in Zhoukou City is not optimistic, the scope of the ward is further expanded, and the harm is still very serious. Fluoride to reduce water is to control the main method of endemic fluorosis, fluoride water purification facilities can be used normally, the key is to implement the construction, management, responsibility system with the three links.
