摘　　要：目的了解内蒙古自治区饮茶型氟中毒流行现状,为制定防控措施提供数据基础。方法2020年,在内蒙古自治区的10个盟(市)、53个旗(县)所有行政村开展饮茶型氟中毒调查。采集每个行政村的基本信息和人口学信息,在每个行政村抽取10户居民入户调查家庭成员基本情况及砖茶饮用情况,并采集家庭砖茶样品测定氟含量。检查行政村内所有8~12岁儿童氟斑牙以及16岁以上成人氟骨症患病情况。结果内蒙古自治区内有39个旗(县)居民有饮用砖茶习惯,其中有大量饮用砖茶习惯人口占总覆盖人口的70.22%(427.85万/609.28万);饮用砖茶人群人均年砖茶消耗量为1.00 kg,人均日砖茶氟摄入量为0.68 mg。共采集砖茶样品24282份,氟含量超标样品占74.77%(18155/24282);除红砖茶氟含量低于国家卫生标准(300 mg/kg)外,其他各品种砖茶均超标。共检查8~12岁儿童97295人,检出氟斑牙6558例,氟斑牙检出率为6.74%;其中,极轻度3623例、轻度2440例、中度489例、重度6例;不同地区、年龄儿童氟斑牙检出率比较,差异均有统计学意义(χ^(2)=6803.76、30.82,P均<0.05)。共检查16岁以上成人115251人,检出氟骨症1691例,成人氟骨症检出率为1.47%;其中,轻度1043例、中度481例、重度167例;不同地区、年龄成人氟骨症检出率比较,差异均有统计学意义(χ^(2)=3584.26、562.67,P均<0.05)。结论内蒙古自治区居民所饮用的砖茶氟含量严重超标,8~12岁儿童氟斑牙及16岁以上成人氟骨症均检出中、重度患者,应持续加强内蒙古自治区饮茶型氟中毒的防治工作。Objective To understand the prevalence of tea-drinking-borne fluorosis in Inner Mongolia Autonomous Region,and to provide a data basis for formulation of prevention and control measures.Methods All administrative villages of 53 banners(counties)in 10 leagues(cities)of Inner Mongolia Autonomous Region were investigated for tea-drinking-borne fluorosis.The basic information and demographic information of each administrative village were collected,and 10 households were selected from each administrative village to investigate the basic information of family members and the drinking situation of brick tea,and collect household brick tea samples to determine the fluorine content.The prevalence of dental fluorosis in children aged 8 to 12 and skeletal fluorosis in adults over 16 years in the administrative villages were investigated.Results There were 39 banners(counties)in Inner Mongolia Autonomous Region that had the habit of drinking brick tea,people who habitually drink brick tea a lot accounted for 70.22%of the total population(4.2785 million/6.0928 million).The per capita annual consumption of brick tea was 1.00 kg and the per capita daily intake of brick tea fluoride was 0.68 mg.A total of 24282 brick tea samples were collected,and the samples with fluorine content exceeding the standard accounted for 74.77%(18155/24282).Except that the fluorine content of black brick tea was lower than the national health standard(300 mg/kg),other varieties of brick tea exceeded the standard.A total of 97295 children aged 8 to 12 years were examined,and 6558 cases of dental fluorosis were detected.The detection rate of dental fluorosis was 6.74%.Among them,3623 cases were very mild,2440 cases were mild,489 cases were moderate and 6 cases were severe.There were significant differences in the detection rates of dental fluorosis in children of different regions and ages(χ^(2)=6803.76,30.82,P<0.05).A total of 115251 adults over 16 years old were examined,and 1691 cases of skeletal fluorosis were detected.The detection rate of adul
