目的了解河北省2008年度低碘盐覆盖地区碘缺乏病防治状况。方法在每个监测县抽取3个乡,在每个乡随机抽取2个村小学,在每所小学抽取40名8～10岁学生,用B超检测其甲状腺容积,采集尿样并测定尿碘含量,在每个乡抽取2个行政村,在每个村对20户18～40岁育龄妇女家中的食盐供应状况进行调查,随机抽检其中10名育龄妇女的尿碘浓度。结果 9个县的8～10岁儿童尿碘中位数在130.1μg/L～277.6μg/L之间,尿碘含量<50μg/L的尿样比例在0～8.9%之间;2个县的8～10岁儿童尿碘中位数>300μg/L。11个县的8～10岁儿童的甲状腺肿大率在0～5.0%之间。育龄妇女家中食盐均为购买,以食用精制盐为主,占总数的91.7%;碘盐和非碘盐分别占76.5%和23.5%。9个县的18～40岁育龄妇女尿碘中位数在131.0μg/L～273.2μg/L之间,尿碘含量<50μg/L的尿样比例在0～14.0%之间。2个县的18～40岁育龄妇女尿碘中位数>300μg/L。结论河北省2008年度大部分低碘盐覆盖地区8～10岁儿童的碘营养处于较适宜的水平,其甲状腺肿大率<5%,18～40岁育龄妇女的碘营养状况良好;个别地区受水源性高碘的影响,8～10岁儿童和18～40岁育龄妇女的碘营养过剩。
Objective To understand the prevention and treatment of iodine deficiency disorders in areas covered by low iodine salt in Hebei Province in 2008. Methods Three townships were selected in each monitoring county. Two village primary schools were randomly selected in each county. 40 students aged 8-10 years were collected in each primary school. The thyroid volume was measured by B ultrasound. Urine samples were collected and urine iodine In each village, 2 administrative villages were sampled. The salt supply status of 20 women of childbearing age from 18 to 40 was surveyed in each village. Urinary iodine concentration of 10 women of childbearing age was randomly selected. Results The median urinary iodine of children aged 8-10 years in 9 counties ranged from 130.1μg / L to 277.6μg / L, and the proportion of urine samples with urinary iodine <50μg / L ranged from 0 to 8.9%. Two counties Of children aged 8 to 10 urinary iodine median> 300μg / L. Goiter in children aged 8-10 in 11 counties ranged from 0 to 5.0%. Salt in the homes of women of childbearing age are purchased, mainly to eat refined salt, accounting for 91.7% of the total; iodized salt and non-iodized salt accounted for 76.5% and 23.5%. The median urinary iodine was between 131.0μg / L and 273.2μg / L for women of childbearing age from 18 to 40 in 9 counties, and the proportion of urine samples with urinary iodine <50μg / L was between 0 and 14.0%. The median urinary iodine of women of childbearing age 18 ~ 40 in two counties was> 300μg / L. Conclusion The iodine nutrition of children aged 8 to 10 years in most areas with low iodine salt coverage in Hebei Province in 2008 was at a suitable level with goiter rate <5%. The iodine nutrition status of women of childbearing age from 18 to 40 was good. In some areas, The high iodine content of water causes iodine excess in children aged 8 to 10 and women of childbearing age from 18 to 40 years old.
