摘　　要：目的了解山西省饮水型地方性氟中毒流行现状,为防治工作提供依据。方法按照《2010年度国家饮水型地方性氟中毒防治项目技术方案》要求,随机选取6个病区县作为监测点,每个监测点随机抽取10个改水工程,监测改水工程运行情况;在每个监测点抽取3个村,对未改水村进行水源水氟检测;对已改水村进行降氟改水工程运行情况调查和水氟测定;在每个村检查全部8～12岁儿童氟斑牙患病情况。儿童氟斑牙调查采用Dean氏法。结果共调查降氟改水工程60个,水氟含量合格工程46个,合格率为76.67%;共监测已改水村17个,水氟含量合格工程11个,合格率为64.71%;监测未改水村1个,水氟浓度均值为2.28 mg/L。已改水村检查8～12岁学生1 409人,氟斑牙检出率为31%,缺损型氟斑牙检出率为5%,氟斑牙指数为0.7;未改水村检查8～12岁学生77人,氟斑牙检出率为29%,氟斑牙指数为0.5。结论山西省儿童氟斑牙病情稳定,部分改水工程水氟超标,今后应加大改水力度,保证工程质量,进一步提高防治效果。Objective To explore the current prevalence of drinking water endemic fluorosis in Shanxi Province,to provide scientific evidence for prevention and control.Methods According to ＂The National Technical Scheme for Drinking Water Endemic Fluorosis Control in 2010＂,6 counties of endemic area were randomly selected as monitoring sites.10 water-improvement projects from each monitoring sites were taken at random to monitor operation of the water-improvement project.Out of the collected 3 villages from each monitoring sites,the village without water-improvement was detected for fluoride content in drinking water,while at the villages with water-improvement,operation of defluoridation projects was investigated and water fluoride was determined.All children at age from 8 to 12 at each village were checked for dental fluorosis with Dean method.Reslts Totally 60 water-improvment projects were investigated.There were 46 projects of qualified water fluorine with qualified rate of 76.67%.And 17 villages with improved water were surveyed,11 were qualified with the qualified rate of 64.71%;1 village was without improved water project with mean water fluorine concentration of 2.28 mg/L.1 409 children at age from 8 to 12 at the water-improvement villages were detected for dental fluorosis with the detection rate of 31% and detection rate of defected dental fluorosis of 5%,and the dental fluorosis index of 0.7.At the village without water-improvement,77 children at age from 8 to 12 were checked for dental fluorosis with the detection rate of 29%,and the dental fluorosis index of 0.5.Conclusions Prevalence of children＇s dental fluorosis is stable in Shanxi Province.Water fluorine content in part of the water-improvement projects is over the standard.Therefore,water-improvement projects should be strengthened to ensure the effectiveness of the control and prevention.
