摘　　要：目的 了解广西壮族自治区北海市8~ 10岁儿童碘缺乏病现状,为采取针对性的防治措施提供依据.方法 按照《全国碘缺乏病监测方案(2016年版)》和《2016-2018年北海市碘缺乏病监测方案》要求,2016-2018年,采用分层多阶段抽样方法,将北海市按照行政区域划分,每个区县分别按照东、西、南、北、中5个方位,各抽取1所小学,每所小学抽取40名8~ 10岁非寄宿学生,采集儿童食用盐盐样和尿样,对盐碘、尿碘含量进行检测,B超法检测儿童甲状腺容积并计算甲状腺肿大率.结果 共调查8~ 10岁儿童800名,其中2016、2017年各调查200名,2018年调查400名;男女比例为1.08∶1.00(415/385);8~ 10岁儿童食用盐碘含量中位数为19.7 mg/kg;合格碘盐食用率为54.4%(435/800).北海市8~ 10岁儿童尿碘中位数为154.3μg/L,8、9、10岁儿童尿碘中位数分别为182.0、141.9、163.3 μg/L;男童尿碘中位数(164.3 μg/L)高于女童(140.0μg/L,Z=-3.765,P< 0.05);不同地区8~10岁儿童尿碘中位数比较差异有统计学意义(H=33.621,P<0.05),铁山港区最低(117.6 μg/L);尿碘中位数在适宜范围(100~<200 μg/L)的占39.3%(314/800).8~ 10岁儿童总的甲状腺肿大率为1.1%(9/800);不同地区儿童甲状腺肿大率比较差异有统计学意义(P<0.05),海城区甲状腺肿大率(3.5%,7/200)高于其他地区.结论 北海市8~10岁儿童碘营养状况为碘适宜,应继续坚持食盐加碘防治碘缺乏病,对不同区县8~ 10岁儿童应采取因地制宜、精准补碘的措施.Objective To understand the current status of iodine deficiency disorders in children aged 8-10 years in Beihai,Guangxi,and to provide evidence for prevention and treatment of the disease.Methods According to the"National Iodine Deficiency Disorders Surveillance Program"(2016 edition)and the"2016-2018 Beihai Iodine Deficiency Disorders Surveillance Program",Beihai was divided into administrative regions by stratified multi-stage sampling method in 2016-2018.Each district and county was divided into five parts according to directions:east,west,south,north and middle.One primary school was selected in each direction and 40 non-boarding students aged 8-10 years were selected from each primary school.Urine samples and edible salt samples were collected from children to detect urinary iodine and salt iodine contents.Thyroid volume of children was determined by B-ultrasound method,and the rate of goiter was calculated.Results A total of 800 children aged 8-10 years were investigated,including 200 in 2016,200 in 2017,and 400 in 2018.The ratio of male to female was 1.08:1.00(415/385);the median salt iodine of children aged 8-10 years was 19.7 mg/kg;the edible rate of qualified iodized salt was 54.4%(435/800).The median urinary iodine of children aged 8-10 years in Beihai was 154.3μg/L.The median urinary iodine of children aged 8,9 and 10 years were 182.0,141.9,163.3μg/L,respectively.The median urinary iodine of boys(164.3μg/L)was higher than that of girls(140.0μg/L,Z=-3.765,P<0.05);there was a difference in the median urinary iodine between children aged 8-10 years in different regions(H=33.621,P<0.05),and Tieshangang District had the lowest(117.6μg/L);the median urinary iodine of 314 people was in the appropriate range(100-<200μg/L),accounting for 39.3%(314/800).The total thyroid goiter rate was 1.1%(9/800)in children aged 8-10 years;the thyroid goiter rate was different in children from different regions(P<0.05),and the thyroid goiter rate(3.5%,7/200)in children aged 8-10 years in Haicheng District was higher tha
