目的掌握新乡市地方性氟中毒病情现状,为制定预防控制策略提供科学依据。方法将新乡市所有地方性氟中毒病村按改水前的水氟含量分为轻、中、重3类,采用流行病学抽样调查方法,2008～2009年对调查村饮水含氟量与有关病情指标进行检查。结果轻、中、重病区水氟含量均值分别为1.03、2.17、3.24 mg/L,范围0.25~7.70 mg/L;8~12岁儿童群体尿氟几何均值为2.10 mg/L,个体最大值12.20 mg/L;成人群体尿氟几何均值为1.55 mg/L,个体最大值10.50mg/L;8~12岁童氟斑牙总检出率、氟斑牙指数分别为64.01%和1.4;16岁以上成人临床与X线氟骨症总检出率分别为5.80%、9.90%。结论目前新乡市地方性氟中毒流行较严重,应进一步加大控制力度。
Objective To grasp the status quo of endemic fluorosis in Xinxiang City and provide a scientific basis for making prevention and control strategies. Methods All the endemic fluorosis villages in Xinxiang City were divided into three categories: light, medium and heavy according to the fluoride content of water before the water diversion, using epidemiological sampling method. From 2008 to 2009, Disease indicators to be checked. Results The mean fluoride levels in the mild, moderate and severe cases were 1.03, 2.17 and 3.24 mg / L, respectively, ranging from 0.25 to 7.70 mg / L. The geometric mean urinary fluoride level was 2.10 mg / L for the children aged 8-12 and the maximum was 12.20 mg / L; the geometric mean of urinary fluoride in adult population was 1.55 mg / L and the maximum was 10.50 mg / L; the total detection rate of dental fluorosis and dental fluorosis index were 64.01% and 1.4 years The above adult clinical and X-ray skeletal total detection rates were 5.80%, 9.90%. Conclusion At present, endemic fluorosis in Xinxiang City is more serious and should be further strengthened.
