摘要
目的了解盐碘浓度调整后浙江省儿童和孕妇碘营养状况及儿童甲状腺肿现况。方法采用人口比例概率抽样方法抽取浙江省30个监测点,以盐碘、水碘、儿童和孕妇尿碘以及8~10岁儿童甲状腺肿大率等指标评价浙江省儿童和孕妇碘营养状况。结果共测定盐样1 565份,盐碘浓度为23.30（4.80）mg/kg,碘盐覆盖率为88.43%,碘盐合格率为95.88%,居民合格碘盐食用率为84.79%;测定8~10岁儿童尿样1 565份,尿碘浓度为171.99（130.89）μg/L;孕妇尿样617份,尿碘浓度为134.14（120.88）μg/L,尿碘浓度〈150μg/L占58.02%;测定管网水66份,水碘浓度为2.42（5.11）μg/L,〈10μg/L的样品占87.88%;B超检查1 565名8~10岁儿童,儿童甲状腺肿大率为4.98%。结论浙江省盐碘浓度调整后儿童碘营养水平处于适宜水平,孕妇碘营养水平低于适宜水平。
Objective To learn the status of iodine nutrition and the goiter of children and pregnant woman in Zhejiang Province after the iodine salt concentration adjustment. Methods The proportionate to population size sampling was applied to select 30 surveillance areas in Zhejiang Province,and iodine nutritional status were evaluated by 4 indicators that include goiter rate in 8- 10 years old children,urine iodine,iodized salt and water iodine. Results The iodine content of1 565 edible salt samples collected from the above children was measured,and the iodine median（ P25- P75） was 23. 30（ 21. 00- 25. 80） mg/kg. The coverage of iodized salt rate was 88. 43%,and 95. 88% iodized salts was qualified. The qualified iodized- salt ingesting rate was 84. 79%. The iodine content of children aged 8- 10 years old and pregnant woman was tested,and iodine median（ P25- P75） was 171. 99（ 113. 00- 243. 89）,134. 14（ 82. 10- 202. 98） g/L respectively. The iodine content of 66 water samples were randomly collected from the surveillance areas to be tested,and iodine median（ P25- P75） was 2. 42（ 1. 17- 6. 28） μg/L. The proportion less than 10 g/L was 87. 9%. The goiter status of 1 565 children were examined by B- type of ultrasonic,and the prevalence of goiter was 4. 98%. Conclusion After the iodine salt concentration adjustment,the status of iodine nutrition in children was in optimum level,but the level of iodine nutrition in pregnant women was less than the state,which should be paid more attention.
