目的了解福建省地方性氟中毒病区现状。方法用分层整群抽样法从全省36个地氟病区县抽取11个病区县,每县抽3个村为调查点,每个调查点测定饮用水氟含量、检查8~12岁儿童氟斑牙患病率,对16岁及以上成人进行氟骨症普查,并对临床疑似氟骨症患者进行X线拍片。结果 33个病区村饮水氟含量均值均<1.0 mg/L,共检出8~12岁儿童氟斑牙病例37例,氟斑牙检出率为5.1%,除改水工程报废的长泰县儿童氟斑牙流行强度为流行边缘外,其它监测县儿童氟斑牙流行强度为阴性,X线氟骨症检出率19.0%(24/126)。结论饮水型地方性氟中毒病区实施改水降氟措施效果显著。
Objective To understand the status of endemic fluorosis in Fujian Province. Methods Stratified cluster sampling method was used to select 11 ward counties from 36 endemic fluorosis districts and counties, and 3 villages in each county were selected as the investigation points. The fluorine content in drinking water was determined at each survey point and examined between 8 and 12 years old Prevalence of dental fluorosis in children, 16-year-old and above adult fluorosis screening, and clinical skeletal fluorosis patients X-ray film. Results The average fluoride content of drinking water in 33 ward villages was less than 1.0 mg / L. A total of 37 cases of dental fluorosis were detected in children aged 8-12 years. The detection rate of dental fluorosis was 5.1%. Except for Changtai The prevalence of dental fluorosis among children in the county was the epidemic edge. The prevalence of dental fluorosis in other monitoring counties was negative. The detection rate of skeletal fluorosis was 19.0% (24/126). Conclusion Drinking water-type endemic fluorosis area to implement the water fluoride effect is significant.
