目的 :了解湖北省蕲春县饮水型地方性氟中毒病情变化和防治效果,为调整防治策略提供科学依据。方法 :采用随机抽样法,对抽取的病区村进行地方性氟中毒有关指标调查,8-12岁儿童采用氟斑牙诊断标准(WS/T208-2011);成人X线氟骨症诊断采用地方性氟骨症诊断标准(WS192-2008);水氟测定采用生活饮用水标准检验方法(GB/T5750.6)。结果 :连续五年监测点水样水氟含量符合国家饮用水标准(≤1.0mg/L);8-12岁儿童氟斑牙检出率平均为2.31%,氟斑牙指数0.04;临床氟骨症检出率0%,成人尿氟均值0.45mg/L。结论 :蕲春县以改水为主的综合性防治措施取得了良好的防治成效,改换水源是预防饮水型地氟病最有效的方法。
Objective: To understand the changes of endemic fluorosis in Guijun County, Hubei Province and its control effect, so as to provide a scientific basis for adjusting control strategies. Methods: A random sampling method was used to investigate the indexes of endemic fluorosis in ward villages. The diagnostic criteria of dental fluorosis (WS / T208-2011) was adopted for children aged 8-12 years. Sexual skeletal fluorosis diagnostic criteria (WS192-2008); Determination of water fluoride drinking water standard test method (GB / T5750.6). Results: The fluoride content of water samples in monitoring sites for five consecutive years met the national drinking water standards (≤1.0mg / L); the detection rate of dental fluorosis in children aged 8-12 years was 2.31% on average, the dental fluorosis index was 0.04; Disease detection rate of 0%, adult urinary fluoride average 0.45mg / L. Conclusion: The comprehensive prevention and cure measures of water quality improvement in Qichun County have achieved good results. The replacement of water sources is the most effective way to prevent drinking water-borne fluoride disease.
