目的了解山东省地方性氟中毒病情现状。方法在13个市采用整群分层随机抽样的方法选择调查点,水氟用氟离子电极法测定,儿童氟斑牙调查采用Dean氏法进行诊断。结果共调查31个县337个病村,水氟>1.00mg/L的病村占54.41%,8￣12岁儿童氟斑牙总患病率为41.39%,斑釉指数为0.95,缺损率为9.10%。在未改水的病村中,有69.77%的病村水氟>1.00mg/L(最大值为6.62mg/L),儿童氟斑牙患病率平均为41.84%,斑釉指数为0.97,缺损率为9.06%;在改水降氟工程运转基本正常的病村中,有37.04%的病村水氟>1.00mg/L(最大值为5.57mg/L),儿童氟斑牙患病率平均为33.29%,斑釉指数为0.73,缺损率为5.98%;在改水工程停用报废的病村中,有72.84%的病村水氟>1.00mg/L(最大值为8.32mg/L),儿童氟斑牙患病率平均为57.18%,斑釉指数为1.35,缺损率为15.02%。结论山东省地方性氟中毒病情仍然十分严重,须进一步落实防制措施和加强监测工作。
Objective To understand the status of endemic fluorosis in Shandong Province. Methods The stratified stratified random sampling method was used to select the investigation points in 13 cities. The water fluorine was measured by fluoride ion electrode method. The children dental fluorosis was diagnosed by Dean’s method. Results A total of 337 sick villages in 31 counties were surveyed, with 54.41% of patients in villages with water fluoride> 1.00mg / L and 41.39% of children aged 8-12 years with spot glaze index of 0.95, with a defect rate of 9.10%. 69.77% of the patients in the uninhabited ward villages had fluoride> 1.00mg / L (the maximum was 6.62mg / L), the prevalence of dental fluorosis in children was 41.84% on average, and the spot glaze index was 0.97. The rate of defect was 9.06%. Among the sick villages whose water and fluoride removal works were basically normal, 37.04% of the patients in the village had fluoride> 1.00mg / L (the maximum was 5.57mg / L), and the prevalence of dental fluorosis in children With an average of 33.29%, a spot glaze index of 0.73 and a defect rate of 5.98%. Among the sick villages with disabled scraps in the water diversion project, 72.84% of the sick villages had fluoride> 1.00mg / L (the maximum value was 8.32mg / L ), The prevalence of dental fluorosis in children was 57.18% on average, the spot glaze index was 1.35 and the defect rate was 15.02%. Conclusions The endemic fluorosis in Shandong Province is still very serious and prevention and control measures must be further implemented.
