摘要
目的了解青铜峡市饮水型地方性氟中毒病区改水后儿童氟斑牙及成人氟骨症的患病情况。方法选择已改水的高氟重病区叶盛镇叶盛5队(改水区1)、高氟轻病区大坝镇新桥5队(改水区2)和未改水的高氟轻病区大坝镇滑石沟5队(未改水区)。于2011年3—4月,对全部670名儿童进行氟斑牙诊断并对所有25岁以上成人共1400名进行氟骨症诊断。结果两个改水区水氟浓度分别为(0.24±0.05)、(0.32±0.07)mg/L,均合格;未改水区水氟浓度为(1.03±0.19)mg/L。改水地区儿童氟斑牙患病率和成人氟骨症患病率均低于未改水地区,差异有统计学意义(P<0.05)。结论青铜峡市地方性氟中毒病区经改水降氟后,饮用水符合卫生要求,但氟斑牙及氟骨症尚存在一定程度的流行。
Objective To evaluate the effects of water improvement aimed at eliminating the prevalence of dental fluorosis and skeletal fluorosis in endemic fluorosis areas of Qingtongxia, Ningxia. Methods By applying epidemiological sample survey methods, 670 children were examined in dental fluorosis and 1 400 adults （〉25 years） were examined in skeletal fluorosis in Yesheng of Yesheng township, the water-improvement area where endemic fluorosis was seriously prevailed, Xinqiao of Daba township which was mild endemic fluorosis area, and Huashigou of Daba township which was non-water-improvement area. Results The fluoride content in drinking water of Yesheng,Xinqiao and Huashigou were （0.24±0.05）, （0.32±0.07） and （1.03±0.19） mg/L. The dental fluorosis and skeletal fluorosis in water-improvenment areas increased significantly than that in non-water-improvement area （P〈0.05）. Conclusion After water improvement, drinking water fluoride levels decrease, dental fluorosis is still prevalent in certain degree in the endemic fluorosis areas of Qingtongxia, Ningxia.
