目的了解厦门市沿海产盐区和非产盐区儿童碘营养状况与甲状腺功能水平,为科学补碘提供依据。方法选择产盐区翔安区和非产盐区集美区为调查点,随机抽取600名8～10岁儿童进行甲状腺检查,随机抽取部分儿童采集尿样、家中盐样和血样,检测含碘量和血清FT3、FT4、TSH、Tg、TPOAb、TT3和TT4水平。结果产盐区与非产盐区合格碘盐食用率为81.5%和98.6%;儿童甲状腺肿大率为3.0%和0.7%,尿碘中位数为202.8和238.4μg/L;两区儿童的甲状腺功能指标均在正常范围,未发现甲亢、亚甲亢及甲减患者,亚甲减患病率为普通人群水平。结论产盐区与非产盐区8～10岁儿童的碘营养水平是适宜的,应坚持食盐加碘措施,加强儿童的科学补碘工作。
Objective To understand iodine nutrition status and thyroid function of children in salt-producing areas and non-salt-producing areas along the coast of Xiamen City, and to provide scientific basis for iodine supplementation. Methods Sixty-eight children aged 8 to 10 years were selected for the thyroid gland examination in Xiang’an District and Jimei District of non-salt producing areas. Thirty children were randomly selected to collect urine samples, salt samples and blood samples at home, And serum FT3, FT4, TSH, Tg, TPOAb, TT3 and TT4 levels. Results The iodized salt rates of 81.5% and 98.6% in salt-producing areas and non-salt-producing areas, 3.0% and 0.7% in children, and 202.8 and 238.4 μg / L in urinary iodine respectively. Thyroid function indicators were in the normal range, no hyperthyroidism, hyperthyroidism and hypothyroidism, hypothyroidism prevalence rate for the general population. Conclusion The iodine nutrition of children aged 8-10 years in salt-producing areas and non-salt-producing areas is suitable. We should insist on salt iodization measures to strengthen children’s scientific iodization.
