摘要
目的通过对广东省高氟病区的改水工程完成情况、水质氟含量达标情况、儿童氟斑牙患病情况的调查,综合评价高氟病区的改水降氟工作施行15年的阶段效果,为进一步做好改水降氟工作提供依据。方法病区情况调查用横断面调查方法,水氟含量测定采用氟离子电极法,儿童氟斑牙检查采用我国氟斑牙临床诊断标准。结果全省高氟病区总的改水率已达92.28%,实施改水的地区饮用水氟含量已降至0.22mg/L,儿童氟斑牙患病率由改水前的60.40%降至41.58%,差异有高度统计学意义(P<0.0001)。结论全省阶段性改水工作的成绩是显著的,具有十分重要的社会效益,加强改水工程的管理和增加资金的投入,是改水降氟工作持续发展的保证。
OBJECTIVE To evaluate the effect of lowering fluoride level in drinking water by altering water resources in endemic fluorosis areas in the past 15 years and provide evidence for further work of altering water resources ,we investigated the quality of lowering fluoride engineering drinking water in endemic fluorosis areasm,the fluoride content in drinking water,and the prevalence rate of dental fluorosis in 8～15 years children.METHODS Cross sectional investigation was adopted in fluorosis areas.The fluoride contents in drinking water were measured by fluoride selective ion electrode.Dental fluorosis of children were examined according to thd clinical diagnosis standard.RESULTS The rate of complete water improving was 92.28%.The average fluoride content was 0.22mg/L.The prevalence rate of dental fluorosis of children decreased from 60.40%to 41.58%with a high statistical significance (P<0.000 1).CONCLUSIONS The achievement of phasic water altering project was remarkable and the social benefit was very noted.The enhancement of management and increase of funds are necessary for ensuring the continual development of defluodidatiion task.
