目的评估无锡市成年居民膳食碘摄入量状况。方法利用该市2005和2010年居民膳食调查资料,中国食物成分表及盐碘和水碘监测数据,计算成年居民膳食碘摄入量,并与我国推荐的膳食碘摄入量标准进行比较。结果无锡市成年居民膳食碘平均摄入量为353.6μg/d,为推荐摄入量(RNI)和可耐受最高摄入量(UL)的235.7%和35.4%。其中食盐碘摄入量270.2μg/d,其贡献率为76.4%。总人群中膳食碘摄入量在RNI～UL之间的个体占97.4%,≥UL的个体仅占0.5%。剔除碘盐,膳食碘主要来源于食物和水,总人群膳食碘摄入量中位数为45.4μg/d,仅为RNI的30.3%。结论无锡市居民膳食碘摄入水平总体是适宜和安全的。
Objective To evaluate the dietary iodine intake of adult residents in Wuxi City. Methods The dietary survey data, Chinese food composition table and salt iodine and water iodine monitoring data of residents in 2005 and 2010 in the city were used to calculate the dietary iodine intake of adults. The iodine intake was compared with the recommended dietary iodine intake of our country. Results The average dietary iodine intake of adult residents in Wuxi was 353.6μg / d, which was 235.7% and 35.4% of the recommended intake (RNI) and tolerable maximum intake (UL) respectively. Among them, salt iodine intake was 270.2μg / d, its contribution rate was 76.4%. The total population of dietary iodine intake among RNI ~ UL individuals accounted for 97.4%, ≥ UL individuals accounted for only 0.5%. Excluding iodized salt, dietary iodine mainly came from food and water. The median dietary iodine intake of the general population was 45.4μg / d, only 30.3% of RNI. Conclusion The dietary iodine intake of Wuxi residents is generally appropriate and safe.
