摘要
目的了解陕西省大荔县地方性氟中毒流行现状。方法2008年采用分层随机抽样方法,对大荔县的8个乡镇20个行政村的8～12岁儿童氟斑牙、16岁以上成年人临床与X线氟骨症患病情况、居民饮用水氟含量及儿童尿氟含量进行调查。结果在调查的20个行政村中,儿童氟斑牙患病率为41.74%,缺损率为1.3%,氟斑牙指数为0.92;16岁以上成年人氟骨症阳性率为20.67%;X线阳性率为61.68%;100份水样氟含量均超过国家标准(≤1.0mg/L),水氟最低1.36mg/L,最高6.99mg/L;儿童尿氟几何平均值为3.95mg/L,92.12%的儿童尿氟超过正常值上限(1.50mg/L)。结论大荔县饮水型地方性氟中毒流行仍较为严重,应加大以改水为主的综合性防治力度。
Objective To determine the prevalence of endemic fluorosis in Dali county,Shaanxi province.MethodsStratified random sampling was performed in 20 administrative villages of eight towns to assess such conditions as dental fluorosis among 8 to 12-year-old children,clinical and X-ray skeletal fluorosis among adults over the age of 16,fluoride content in drinking water and fluoride content in urine of children in Dali in 2008.Results In the twenty administrative villages investigated,the prevalence of children dental fluorosis was 41.74% with the defect rate of 1.3%.The dental fluorosis index reached 0.92.The positive rate of skeletal fluorosis among adults over the age of sixteen was 20.67%;and X-ray positive rate 61.68%.A total of 100 water samples resulted in a fluoride content exceeding the national standard（≤ 1.0 mg/L）,the lowest water fluoride 1.36 mg/L with a maximum of 6.99 mg/L.The geometric mean urinary fluoride among children reached 3.95 mg/L,92.12% of children having urinary fluoride above the normal upper limit（1.50 mg/L）.Conclusion The prevalence of endemic fluorosis associated with drinking water was severe in Dali county.Therefore,water-improvement-based comprehensive prevention and treatment efforts shall be made.
