摘　　要：目的 了解内蒙古自治区饮茶型氟中毒病区病情变化趋势,评价防控措施效果.方法 2009、2012年,在内蒙古自治区分别抽取相同的6个监测旗县,每个监测旗县抽取5个病区村,每个监测村抽取10户家庭,检测砖茶氟含量;检查病区村所有8～ 12岁学生氟斑牙患病情况及所有36～45岁成人氟骨症患病情况.2012年,在每个监测村,按东、南、西、北、中5个方位在采集饮用水源水样各l份,检测水氟含量.结果 2009年监测村砖茶氟含量均值为541.48 mg/kg,氟含量≤300 mg/kg的占17.63％（49/278）;2012年砖茶氟含量均值为536.06 mg/kg,氟含量≤300 mg/kg的占11.00％（33/300）.水氟超标村数占总数的40.00％ （12/30）.2009年儿童氟斑牙检出率为52.39％（274/523）,其中极轻、轻、中、重度病例分别占9.56％（50/523）、19.86％（104/523）、21.03％（110/523）、1.91％（10/523）;2012年儿童氟斑牙检出率为35.71％（200/560）,其中极轻、轻、中、重度病例分别占14.11％（79/560）、11.43％ （64/560）、9.64％（54/560）、0.54％（3/560）;2012年与2009年相比,中、重度病例所占比例减少,病情有所下降（W=40 696.0,P＜0.01）.2009年成人氟骨症检出率为23.52％（167/710）,其中轻、中、重度病例分别占17.32％（123/710）、4.51％（32/710）、1.69％ （12/710）;2012年成人氟骨症检出率为20.12％（103/512）,其中轻、中、重度病例分别占17.38％（89/512）、2.54％（13/512）、0.20％（1/512）;2012年与2009年比较,中、重度病例减少,病情有所下降（W=12 797.5,P＜0.01）.结论 内蒙古自治区饮茶型氟中毒病情得到了一定程度的控制,但部分地区高氟砖茶危害仍很严重,防治工作还需要进一步加强.Objective To understand the trend of drinking-tea type fluorosis in the diseased areas in Inner Mongolia Autonomous Region,and to evaluate the effect of prevention and control measures.Methods In 2009 and 2012,6 monitored counties were selected in Inner Mongolia Autonomous Region; 5 diseased villages were selected in each monitored county,and 10 families were selected in each monitored village; fluorine content of brick tea was tested,and dental fluorosis conditions of all 8 to 12-year-old students and skeletal fluorosis conditions of all 36 to 45-year-old adults were examined.In 2012,in each monitored village,1 water sample of the drinking water source was collected respectively from five positions（east,south,west,north and the central of the village）,and fluoride content of drinking water wastested.Results In 2009,the mean of brick tea fluorine content was 541.48 mg/kg in the monitored villages,and the fluoride content ≤ 300 mg/kg accounted for 17.62%.（49/278）.In 2012,the mean of brick tea fluorine content was 536.06 mg/kg,and the fluoride content ≤300 mg/kg accounted for 11.00%（33/300）.Total exceeding standard rate of the water fluoride content was 40.00%（12/30）.In 2009,the detection rate of the children＆#39;s dental fluorosis was 52.39% （274/523）,very mild,mild,moderate and severe cases accounted for 9.56%（50/523）,19.86%（104/523）,21.03%（110/523） and 1.91%（10/523）,respectively.In 2012,the detection rate of the children＆#39;s dental fluorosis was 35.71%（200/560）,very mild,mild,moderate and severe cases accounted for 14.11% （79/560）,11.43% （64/560）,9.64% （54/560）,and 0.54% （3/560）,respectively.Compared with 2009,the proportion of moderate and severe cases reduced in 2012（W =40 696.0,P 〈 0.01）.In 2009,the detection rate of adult skeletal fluorosis was 23.52% （167/710）,mild,moderate and severe cases accounted for 17.32%（123/710）,4.51%（32/710） and 1.69%（12/710）,respectively.In 2012,the detection rate of adult skeletal fluorosis wa
