目的　对枣阳市改水降氟工程防治地氟病效果进行评价，科学地指导防制工作。方法　对监测点改水后的水氟、8～12岁儿童氟斑牙及尿氟进行监测。结果　改水后的水质好，水氟含量稳定。改水前后水氟含量下降1.79 mg/L，十几年来一直控制在国家标准1.0 mg/L以内，无较大波动。8～12岁儿童尿氟几何均值由改水前6.28 mg/L降至0.82 mg/L，氟斑牙患病率由改水前85.9 ％降至1997年的13.0％，氟斑牙指数由1.74降到0.29，流行强度由中等降至阴性，达到非病区标准。结论　改水降氟工程成效显著。病区人民只有通过改水降氟这一经济有效措施，饮用合乎国家卫生标准的低氟卫生水才能预防氟中毒。
