2015年上海市重点人群碘营养状况监测

Surveillance on iodine nutritional status in target population in Shanghai

摘要

摘要:
目的掌握2011年《食用盐碘含量》标准实施后上海地区孕妇和学龄儿童的碘营养状况。
方法按人口比例概率抽样法抽取30个街道(镇)，每个街道(镇)中随机抽取1所小学，每所小学中随机抽取50名8~10岁学生，测量其甲状腺容积和尿碘含量，并检测其家中食用盐碘含量。在每个抽取的街道(镇)，抽样检测20名孕妇的尿碘含量。
结果8~10岁学龄儿童甲状腺肿大率为0.9%。8~10岁学龄儿童、孕妇的尿碘中位数分别为171.40、126.53 μg/L。8~10岁学龄儿童家中合格碘盐食用率为72.52%，碘含量中位数为24.8 mg/kg。
结论上海市儿童甲状腺肿大率低于国家标准，儿童碘营养水平适宜，孕妇碘营养不足。食盐中碘的含量需提高至最优水平。要加强孕妇碘营养健康教育。

Abstract:
ObjectiveTo ascertain iodine nutritional status of pregnant women and children in Shanghai since the implementation of "Salt Iodine Content Standard" in 2011.
MethodsBy population proportion probability sampling, 30 sub-districts(towns) were chosen, with one primary school was randomly sampled in each sub-districts(towns). And 50 students aged 8-10 in every school were randomly selected to test their urinary iodine and thyroid volume, and their household iodized salt concentration determined. And 20 pregnant women were selected to test their urinary iodine in each sub-districts(towns).
ResultsThe goiter rate of 8-10 years old children was 0.9%. The medians of urinary iodine concentration of 8-10 years old children and pregnant women were 171.40 μg/L and 126.53 μg/L, respectively. The consumption rates of qualified iodized salt were 72.52%. The median of iodine content concentration in salt was 24.8 mg/kg.
ConclusionIn Shanghai, the goiter rate of children was lower than that of the national standard. Iodine nutritional status of children is proper, but the pregnant women were deficient in iodine nutrition. Therefore, iodized salt concentration should be improved to the optimal level. Health education for pregnant women should be strengthened.
