摘要
目的了解山东省东营市地方性氟中毒流行现状,为制定防控策略提供科学依据。方法采用流行病学抽样方法,调查丁五等6个病村的居民饮用水氟含量,检测8~12岁儿童尿氟含量,调查8-12岁儿童氟斑牙检出率,16岁及以上成人临床与X线氟骨症检出情况。结果6个病村饮用水平均水氟浓度为3.04 mg/L,22份水样水氟浓度均超过国家标准（≤1.0 mg/L）,最高者达4.15 mg/L;8-12岁儿童氟斑牙平均检出率59.7%,缺损率11.8%,斑釉指数1.20,最高的码头村氟斑牙检出率达69.4%,缺损率21.5%,斑釉指数1.51;8-12岁儿童尿氟几何均值2.40 mg/L,6个病村均未达到≤1.5 mg/L的控制标准;成人临床氟骨症检出率和X线阳性检出率均为14.8%,病情以码头村最重,并出现2例X线Ⅱ期氟骨症患者。结论东营市地方性氟中毒病情尚未得到控制,需加大改水力度,控制氟源,尽快落实防制措施,以期早日摆脱高氟危害。
Objective To investigate the epidemic status of endemic fluorosis in Dongying city. Methods The fluoride concentration of drinking water was tested in samples collected from 6 villages in 2008.Urinary fluoride levels and proportion of dental fluorosis were also evaluated for children aged 8-12 years old.The prevalence of skeletal fluorosis was diagnosed by X-ray in individuals over 16 years old.Results The average fluoride concentration of drinking water was 3.04 mg/L,which was higher than the national standard（≤1.0 mg/L）.The maximum concentration of fluoride was as high as 4.15 mg/L.The prevalence rate of dental fluorosis was 59.7% in children aged 8-12 years old with average index of which as 1.2 and rate of dental damage as 11.8%.The worst situation was found in Matou Village,which had average index of dental fluorosis,prevalence rate of dental fluorosis and of dental damage as 1.51,69.4% and 21.5% respectively.The geometric mean concentration of urinary fluoride was 2.40 mg/L in children aged 8-12 years old.The prevalence rate of skeletal fluorosis was 14.8% in adults diagnosed by either X-ray or clinical symptom.Two cases of phase II skeletal fluorosis were found in Matou village.Conclusion The epidemic of endemic fluorosis was still serious in Dongying city.The measures of improvement of water quality and water defluoridation should be carried out as promptly as possible to prevent the endemic fluorosis in the city.
