目的调查济南市8~10岁儿童、孕妇和哺乳期妇女碘营养状况,为重点人群科学补碘提供依据。方法在济南市9个县(市区)中,每县(市区)按照东、西、南、北、中5个方位各取一个乡镇,每个乡镇抽一个小学,每个小学随机抽取100名8~10岁学生,每个乡镇5个村,每个村随机抽取10~20名孕妇和哺乳期妇女,采集尿样检测碘含量。共计儿童1 837名,孕妇749名,哺乳期妇女458名。结果 8~10岁儿童、孕妇和哺乳期妇女尿碘中位数分别为187.9μg/L、177.3μg/L、220.8μg/L,为碘适宜水平;11.10%儿童、40.32%孕妇和28.17%哺乳期妇女处于碘营养不足水平,17.20%儿童、10.20%孕妇和11.14%哺乳期妇女处于碘营养过量水平;不同县(市区)8~10岁儿童、孕妇和哺乳期妇女尿碘水平差异均有统计学意义(P<0.05)。结论三种重点人群的碘营养状况处于适宜水平,仍存在一定比例的碘缺乏和碘过量状况,应针对不同地区的不同人群制定补碘政策。
Objective To investigate the iodine nutrition status of children aged 8-10 years, pregnant women and lactating women in Ji’nan City, and provide the scientific basis for iodine supplementation in key populations. Methods Nine counties (urban districts) in Jinan City were selected. Each county (urban area) took one township in each of the five orientations of East, West, South, North and Central, and each township took a primary school. Each primary school randomly selected 100 Name 8 to 10-year-old students, each village 5 villages, each village randomly selected 10 to 20 pregnant and lactating women, urine samples were collected to detect iodine content. A total of 1 837 children, 749 pregnant women and 458 lactating women were enrolled. Results The median urinary iodine of children aged 8-10 years, pregnant women and lactating women were 187.9μg / L, 177.3μg / L and 220.8μg / L, respectively, which were suitable for iodine; 11.10% of children, 40.32% of pregnant women and 28.17% of lactating women Women with iodine deficiency were in under-nutrition status, 17.20% of children, 10.20% of pregnant women and 11.14% of lactating women were over-iodized. Urinary iodine levels in children aged 8-10 years, pregnant women and lactating women in different counties (urban areas) Statistical significance (P <0.05). Conclusion The iodine nutrition status of the three kinds of key population is at an appropriate level, and there is still a certain proportion of iodine deficiency and iodine excess status. The policy of iodine supplementation should be formulated for different populations in different regions.
