摘　　要：目的了解GB 26878—2011《食品安全国家标准食用盐碘含量》(以下简称新标准)正式实施1年后淮安市不同水碘含量地区儿童的碘营养状况。方法于2016年5—9月,选择不同水碘含量(6.1~38.1μg/L)的金湖、盱眙、洪泽3个县,每个县按东西南北中5个方向各随机抽取1个镇,在每个镇的中心小学各随机抽取40名8~10岁学龄儿童(男女各半)作为调查对象。检测儿童家庭食用盐碘含量、儿童尿碘浓度、甲状腺肿大(以下简称甲肿)及甲状腺囊肿等情况。结果共监测食盐600份(均为碘盐),水碘<10μg/L、10~30μg/L和>30μg/L的3类地区的盐碘合格率、合格碘盐食用率均超过98%。儿童尿碘的范围为19.3~815.4μg/L,中位数为176.6μg/L;<100μg/L样品所占百分比均小于50%,尿碘<50μg/L样品所占百分比均小于20%。水碘<10μg/L、10~30μg/L和>30μg/L的3类地区儿童尿碘的中位数分别为126.4、179.5、204.3μg/L。水碘>10μg/L的两组儿童的尿碘中位数及尿碘值>300μg/L所占百分比均高于水碘<10μg/L组,差异有统计学意义(P<0.01);而水碘>10μg/L两组儿童间尿碘的中位数及尿碘值>300μg/L所占百分率比较,差异均无统计学意义(P>0.05)。儿童的甲肿率、囊肿率和结节率分别为3.33%,0.17%,5.67%。甲肿率和囊肿率均随着水碘浓度的升高而增加,差异均有统计学意义(P<0.05)。不同水碘地区儿童的结节率间比较,差异无统计学意义(P>0.05)。结论供应新标准碘盐后,水碘含量<10μg/L地区儿童碘营养适宜。Objective To understand the iodine nutritional status of children in areas with different levels of water iodine in Huai＇an one year after the formal implementation of GB 26878-2011 Iodine Concentration in Edible Salt. Methods During May and September in 2016,Jinhu county,Xuyi county and Hongze county with different levels of water iodine（6.1-38.1 μg/L） were selected,and five towns were randomly selected according to the five directions of east,south ,west,north and center in each county.A total of 40 children aged 8-10 years were randomly selected as monitoring objects from each Town Central Primary School. Urine samples were collected and detected from these children and their household salt samples were detected at the same time. Thyroid enlargement and thyroglossal cyst were both examined. Results A total of 600 salt samples were monitored which were all iodized salt. The qualified rates of iodized salt and household usage rates of adequately iodized salt were all more than 98% of three type areas with different levels of water iodine （〈10 μg/L, 10-30 μg/L and〉30 μg/L）. The range of urinary iodine of children was 19.3-815.4 μg/L and the median was 176.6μg/L. The percentage of samples with urine iodine 〈100 μg/L was less than 50% and it was less than 20% in samples with urine iodine 〈50 p,g/L. The urinary iodine median of children were 126.4 μg/L, 179.5 μg/L and 204.3 μg/L in three types areas with different levels of water iodine（〈10 μg/L, 10-30 μg/L and 〉30μg/L）. The urinary iodine medians and the percentage of samples with urine iodine 〉300 μg/L for children in areas with water iodine content of 10-30 μg/L and〉30 μg/L were both significantly higher than those in area with water iodine content of 〈10 μg/L （P〈0.01）, there were no difference between those two groups with water iodine content 〉10 μg/L （P〉0.05）. The prevalence rates of goiter , thyroid cyst and thyroid nodule in children were 3.33% ,0.17% and 5.67% respectively. Both the detection r
