摘要
目的了解浙江省居民的碘营养状况，评估浙江省不同地区不同人群碘营养水平。方法采用分层整群抽样方法，抽取浙江省22个县区的居民作为研究对象进行问卷调查，同时检测饮用水水碘浓度、食用盐盐碘浓度以及尿碘浓度等，计算浙江省不同地区不同人群碘营养水平。结果浙江省居民饮用水水碘中位数为2．42μg／L；居民家庭食用盐盐碘中位数为28．8mg／kg，全省碘盐覆盖率为79．54％，合格碘盐食用率为76．65％；居民尿碘中位数为161μg／L，〈100μg／L者占25．92％，≥300μg，L者占15．30％，其中妊娠期妇女尿碘中位数为138μg／L；浙江省居民碘摄入来源中水、盐、其他食物的构成比分别为1．70％、76．41％和21．89％。结论浙江省居民碘营养水平总体上适宜，但妊娠期妇女碘营养水平处于不足状态。
Objective To understand the current status of iodine nutrition among the community residents to compare the level of iodine nutrition in different areas and groups of populations in Zhejiang province. Methods Stratified cluster sampling method was adopted and residents from twenty-two communities in Zhejiang province were selected. A cross-sectional survey was conducted, using questionnaires, laboratory tests, on urinary iodine, water iodine and the concentration of the iodine in salt, which had played positive roles in the calculation of the level of iodine nutrition. Results Results of the iodine nutrition in this cross-sectional survey were as follows： the median water iodine and salt iodine of Zhejiang were 2.42 ktg/L and 28.8 mg/kg, respectively. The coverage of iodized salts was 79.54%, with the ingesting rate of qualified iodizedsalt as 76.65% and the median content of urinary iodine in the population of Zhejiang was 161 μg/L. The average iodine content among pregnant women was 138 μg/L, with the percentage of samples less than 100 μg/L as 25.92%, more than 300 μg/L as 15.30%. The proportions of iodine intake through water, salt and other foods were 1.70%, 76.41% and 21.89%, respectively. Conclusion The status of iodine nutrition in Zhejiang province in general seemed to be appropriate, but the level of iodine nutrition in pregnant women was less than the requirement, which should call for attention.
