目的分析食盐加碘浓度调整前后淄博市8~10岁儿童碘营养状况,为合理补碘提供科学依据。方法对2011年和2015年淄博市7个碘缺乏县(区)的居民户食用盐及8~10岁儿童尿样和甲状腺容积进行监测,并对2年监测结果进行对比。结果 2011年和2015年居民户食用盐碘中位数分别为30.15和22.70 mg/kg,差异有统计学意义(U=5.62,P<0.01);2011年和2015年儿童尿碘中位数分别为194.90和187.00 g/L,差异有统计学意义(U=5.38,P<0.01);2011年和2015年8~10岁儿童甲状腺肿大率分别为6.70%和7.39%,差异无统计学意义(χ~2=0.23,P>0.05)。结论淄博市实施食用碘盐含量新标准后,盐碘中位数有所降低,儿童尿碘中位数处在适宜范围。在合理调整食盐碘含量的同时,应加强碘摄入量对8~10岁儿童甲状腺容积影响的研究。
Objective To analyze the iodine nutrition status of children aged 8 ~ 10 years in Zibo City before and after the adjustment of salt iodine concentration to provide a scientific basis for iodine supplementation. Methods The urinary and thyroid volumes of the residents in 7 iodine deficiency counties (districts) and the children aged 8 ~ 10 years in 2011 and 2015 were monitored, and the results of two years monitoring were compared. Results In 2011 and 2015, the median of salt intake and iodine intake of residents was 30.15 and 22.70 mg / kg, respectively, with statistical significance (U = 5.62, P <0.01). The median urinary iodine of children in 2011 and 2015 were respectively The difference was statistically significant (U = 5.38, P <0.01). The goiter rates of children aged 8-10 years in 2011 and 2015 were 6.70% and 7.39%, respectively, with no significant difference (χ ~ 2 = 0.23, P> 0.05). Conclusion After the implementation of the new standard of iodized salt content in Zibo City, the median of salt and iodine decreased, and the median of urinary iodine in children was within the appropriate range. In a reasonable adjustment of salt iodine content at the same time, we should strengthen the iodine intake of children aged 8 to 10 thyroid volume impact study.
