摘　　要：目的为了解降氟改水后永济市饮水型地方性氟中毒的流行病学概况及消长趋势,为今后的防治工作提供科学依据。方法采用分层整群抽样方法在永济市氟中毒流行区按轻、中、重病区共抽查18个病区村,进行水氟、8～12岁儿童氟斑牙、尿氟及16岁以上成人氟骨症流行病学调查。水氟和尿氟采用氟离子选择电极法测定。结果共抽检饮用水81份,超标5份,超标率6.17%,水氟均值0.70 mg/L,最大值2.41 mg/L。8～12岁儿童281名,氟斑牙患病率为41.64%,缺损率为16.37%,氟斑牙指数1,尿氟均数为2.38 mg/L。共调查16岁以上成人19 662人,氟骨症患病人数663人,患病率为3.37%。结论永济市氟中毒病情已处于稳定状态,但依然属于地方性氟中毒的流行区,以降氟改水为主的综合防治措施仍需进一步加强,监测工作不能放松。Objective To explore the prevalence of endemic fluorosis in the area where the drinking water was improved, to pro- vide evidence for the disease control and prevention. Methods Eighteen villages were selected in yongji according to the distri- bution feature of disease area. The investigational spots were selected by stratified and clustered sampling in that county. Dental fluorosis and urine fluorine content of 8 to 12 years oht children amt the adults who were elder than sixteen were examined in the selected spots. The fluoride levels of in water and urine were determined by fluoride selective ion electrode. Results The sum number of water was 81 aml the overall standard water was 5, accounting for 6.17%. There were 281 children were surveyed and the dental fluorosis rates was 41.64% ,the index was 1. Average urine fluorine of chihlren was 2.38 rag/l,. There were 663 suf- ters nf 19 662 adults, accounting for 3.37%. Conclusions The prevalence of endemic florosJs is in a steady state but it is still a epidemical area in Yuneheng. Theretore,we should strength water- improving projects and our work to raise the effectiveness of prevention.
