摘要
目的了解海岛居民碘营养现状,为有效落实科学补碘防控策略提供依据。方法采用分层随机抽样法选择不同碘盐覆盖率地区人群,调查居民户饮用水水碘含量、碘盐覆盖率、合格碘盐食用率,以及0～2岁婴幼儿、8～10岁儿童、成人、孕妇、哺乳期妇女的尿碘水平。结果碘盐高覆盖率组儿童、成人、哺乳期妇女、0～2岁婴幼儿尿碘水平均在适宜范围;碘盐低覆盖率组成人、哺乳期妇女的尿碘水平则低于WHO推荐值,儿童也处于WHO推荐值的下限边缘;不同碘盐覆盖率地区孕妇尿碘水平均低于WHO推荐值。结论现有的碘盐浓度下海岛居民碘营养水平是适宜的,不存在碘过量的问题,海岛同样需供应碘盐;应高度关注孕妇的碘营养状况,并将这部分人群监测纳入常规监测范围。
Objective To understand iodine nutrition status of residents living in island,and provide evidence for the effective implementation of preventive strategy of scientific iodine supplement.Methods Using stratified cluster sampling,several groups of residents from different coverage rate of iodized salt areas were investigated on iodine content in household drinking water,coverage rate of iodized salt,proportion of households using adequately iodized salt and urine iodine（UI） level in children aged 0 to 2,8 to 10 years old children,adults,pregnant and lactating women,respectively.Results The median UI level of children,adults,lactating women and children aged 0 to 2 in high coverage rate of iodized salt group were all in the adequate ranges.The median UI level of adults,lactating women in low coverage of iodized salt group were lower than WHO recommendation and children just reached the lower limit of WHO recommendation.In this survey,we found that the UI levels of pregnant women in different coverage rate of iodized salt areas were relatively lower than limit of WHO recommendation.Conclusion The iodine nutrition level of residents living in island is adequate in the consumption of iodized salt with current concentration,and the iodine excess doesn＇t exist.The supply of iodized salt is still needed in island.We should highly concern about the iodine nutrition status of pregnant women,and the monitoring for this part of population should be in the priority and taken into our routine monitoring.
