许昌市饮水型地方性氟中毒病区控制评价

目的为评价氟中毒病区控制效果并对未控制病区村原因进行分析,为下一步防治提供科学依据。方法调查全部氟中毒病区村改水工程运行状况、水氟含量、8-12岁儿童氟斑牙情况,并收集病区村历年监测数据进行分析。结果许昌市病区村改水工程正常运转且水氟合格率95.14%,8-12岁儿童氟斑牙患病率为14.44%,病区村控制率为84.14%。40.00%的未控制村水氟超标或5年内曾超标,54.29%的未控制村供水氟合格水≤5年,5.71%的未控制村供水氟合格水>5年。结论许昌市氟病区改水工程运行良好,防治效果明显。病区改水时间尚短和工程水氟超标是病区村不能控制的主要原因,整改超标工程和健康教育是下一步防治重点。

Control effect evaluation on disease area of drinking water type endemic fluorosis in Xuchang City
