目的 掌握吉林省地方性氟中毒病情现状 ,为今后地方性氟中毒防治提供科学依据。方法 在 3个重点病区县中 ,按非、轻、中、重病区总人口的 10 %抽取调查点 ,调查 8～ 12岁儿童氟斑牙、成人重度氟骨症患病情况 ;检测饮水氟含量、8～ 12岁儿童尿氟含量 ;调查改水情况。结果 8～ 12岁儿童氟斑牙患病率为 45 .2 3 %,未查出重度氟骨症患者 ;水氟含量的中位数为 1.49mg/L ,8～ 12岁儿童尿氟含量的中位数为 1.5 7mg/L ;病区改水率为 3 3 .2 1%,使用率为 67.3 4%。结论 吉林省地方性氟中毒病情有转轻的趋势 ,防氟改水工作需进一步加强
Objective To grasp the status quo of endemic fluorosis in Jilin Province and provide a scientific basis for the prevention and treatment of endemic fluorosis in the future. Methods In 3 key wards and counties, 10% of the total population of non-light, moderate and severe wards were surveyed to investigate the prevalence of dental fluorosis and dental fluorosis in children aged 8 to 12 years. Content, urinary fluoride content of children aged 8 to 12 years; survey of water conditions. Results The prevalence of dental fluorosis in children aged 8 ~ 12 years was 45.23%, and no patients with severe skeletal fluorosis were found. The median of fluoride levels in water was 1.49 mg / L, urinary fluoride content in children aged 8 ~ 12 years Median 1.5 7mg / L; Ward water rate was 33.21%, the utilization rate was 67.3 4%. Conclusions The endemic fluorosis in Jilin Province tends to turn light and the work of anti-fluoride and water diversion should be further strengthened
