我国不同地区城市居民膳食碘摄入量调查分析

目的：调查并计算出我国不同地区城市居民人均每日单纯从食物中摄入的碘含量是否达到适宜水平,为我国不同城市地区居民碘营养合理摄取提供建议。方法：2009年4月-2010年4月采用典型调查方法在我国南方城市福建省龙岩市、中部城市山东省淄博市、北方城市甘肃省武威市3类地区各选择1~2个街道的居民,分别用食物频率问卷法收集食物碘摄入量数据和七日称量法收集从调味品中摄入的碘含量数据,推算出3类城市居民人均日碘摄入量。结果：我国3类城市中,福建省、山东省及甘肃省城市居民人均每日从膳食中摄入碘量分别为98.30、74.00及68.03 μg/d,均小于碘摄入量的最佳值150 μg/d。福建省、山东省及甘肃省城市居民摄食碘盐中碘含量占4种调味品(碘盐、鸡精、味精及酱油)摄碘总量的贡献率分别为99.48%、99.62%和98.46%,均远远高于其他调味品碘贡献率。结论：我国3类城市居民每人每日单纯从食物中摄入的碘含量没有达到WHO推荐的标准,应继续食用加碘盐以满足机体日常需要。

Survey analysis on dietary iodine intake of urban residents in different regions of China

Objective To investigate and calculate the iodine intake of urban residents in different regions in China and assess the results with the criterion in order to offer advice to reasonable iodine intake for people in daily life.Methods Food frequency questionnaire and the 7th weighing methods were used to collect the data of iodine intake of urban residents of three different regions,which were Longyan city of Fujian province,Zibo city of Shandong province and Wuwei city of Gansu province,in China from April 2009 to April 2010.Results The iodine intakes of the urban residents of Fujian Province,Shandong Province,and Gansu Province were 68.03,74.00,and 98.30 μg·d-1,respectively.The iodine contribution rates of iodized salt among four condiments were 99.48%,99.62%,and 98.46%,respectively.Conclusion The iodine intakes of urban residents in three different regions in China are lower than 150 μg·d-1,so the inhabitants still need iodine supplementation from iodized salt.
