【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(P0.01);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(P0.05)。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(P0.05)。不同水碘地区儿童的结节率间比较,差异无统计学意义(P0.05)。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。
[Abstract]:Objective to understand the iodine nutrition status of children in different water iodine content areas of Huaian City after the implementation of GB 26878-2011 National Standard for Food Safety iodine (hereinafter referred to as the new standard). Methods from May to September 2016, Jinhu, Xuyi and Hongze counties with different water iodine contents of 6.1g / L and 38.1 渭 g / L, were randomly selected from each county according to the five directions of east-west, north-south and north-south. A total of 40 10-year-old school children (half male and half male) were randomly selected from each central primary school in each town. The contents of iodine in salt, urine iodine concentration, goiter and thyroid cyst were measured. Results A total of 600 salt samples (all iodized salt, 10 渭 g / L ~ 1030 渭 g 路L ~ (-1) of water iodine) and 30 渭 g / L ~ (-1) L ~ (-1) of water iodized salt were monitored. The qualified iodized salt consumption rate exceeded 98%. The range of urinary iodine in children was 19.3 渭 g / L 815.4 渭 g / L, the median value was 176.6 渭 g / L and the percentage of 100 渭 g / L sample was less than 50g / L, and the percentage of urine iodine 50 渭 g / L sample was less than 20%. The median of urinary iodine in children in water iodine 10 渭 g / L 1030 渭 g / L and 30 渭 g / L was 126.4179.5 渭 g / L and 204.3 渭 g / L, respectively. The percentage of urinary iodine median and urinary iodine value 300 渭 g / L in water iodine 10 渭 g / L group was higher than that in water iodine 10 渭 g / L group, the difference was statistically significant (P 0.01), while the percentage of urinary iodine median and urinary iodine value 300 渭 g / L in water iodine 10 渭 g / L group was higher than that in water iodine 10 渭 g / L group. The difference was not statistically significant (P 0.05). The goiter rate, cyst rate and nodule rate of children were 3.330.17 and 5.67, respectively. The rate of goiter and cyst increased with the increase of iodine concentration in water, and the difference was statistically significant (P 0.05). There was no significant difference in nodule rate among children in different water iodine areas (P 0.05). Conclusion after supplying the new standard iodized salt, iodine content in water is suitable for iodine nutrition in children in 10 渭 g / L area.
