目的 评估浙江省居民膳食碘摄入水平及食物贡献率.方法 2010年4月采用多阶段分层整群随机抽样方法将浙江省9798名居民纳入调查,采用24 h膳食回顾法结合查询《食物成分表》的方法获得居民食物碘摄入量,并采集饮用水、食用盐检测碘含量.结果 9798名调查对象中居民膳食碘摄入量为(395.13±78.16) μg/d,介于推荐摄入量(RNI)的150μg/d与可耐受最高摄入量(UL) 1000 μg/d之间;其中有18.40%(1803/9798)的居民碘摄入量低于平均需要量(EAR),4.68%(459/9798)的居民每日碘摄入量高于UL.各地区居民平均摄入量结果显示,内陆地区、次沿海地区、沿海地区依次为(498.85±96.77)、(384.50±88.76)、(326.33±78.32)μg/d(F=27.17,P<0.05);居民膳食碘摄入量不足EAR值的比例沿海地区、次沿海地区、内陆地区依次为34.89%(1239/3551)、10.48%(370/3530)、7.14% (194/2717) (x2 =62.87,P<0.01),高于UL值的比例次沿海地区、内陆地区、沿海地区依次为5.10% (180/3530)、4.86%(132/2717)、4.14%(147/3551).在未考虑烹调损失的情况下,食盐、各类食物、饮用水的碘的平均贡献率依次为74.92%(296.03/395.13)、23.85%(94.24/395.13)、1.23%(4.86/395.13);分析各地区食盐的贡献率,内陆地区、次沿海地区、沿海地区依次为83.72%(417.64/498.85)、73.05%(280.88/384.50)、66.83%(280.09/326.33);饮用水的贡献率依次为次沿海地区(1.61%,6.19/384.50)、沿海地区(1.44%,4.70/326.33)、内陆地区(0.65%,3.24/498.85)(x2=7.24,P=0.032);紫菜的贡献率依次为沿海地区(22.57%,73.65/326.33)、次沿海地区(17.11%,65.79/384.50)、内陆地区(8.09%,40.36/498.85)(x2=82.17,p<0.01);海鱼的贡献率依次为沿海地区(2.38%,7.77/326.33)、次沿海地区(0.72%,2.77/384.50)、内陆地区(0.68%,3.39/498.85)(x2=19.47,P=0.0
Objective To assess the level of dietary iodine intake and its contribution in Zhejiang.Methods A total of 9798 subjects were recruited in this survey with multi-stage stratified cluster random sampling method in April,2010,the 24-hours dietary recall method and the "food composition table" were used to obtain the dietary iodine intake,and edible salt and drinking water samples were collected to detect the content of iodine.Results A total of 9798 subjects were included in this survey.The mean intake of dietary iodine in Zhejiang residents per standard man-days was (395.13 ± 78.16) μg/d,which in between of Recommended Nutrient Intake (RNI) 150 μg/d and Tolerable Upper Intake Level (UL) 1000 μ g/d; the iodine intake of 18.40% (1803/9798) subjects was lower than estimated average requirement of iodine (EAR),4.68% (459/9798) subjects was higher than the UL.The means of dietary iodine intake in various areas were (498.85 ± 96.77) μg/d,(384.50 ± 88.76) μg/d and (326.33 ±78.32) μg/d in inland areas,sub-coastal areas and coastal areas,successively (F =27.17,P < 0.05) ; the proportions of dietary iodine intake lower than EAR were 34.89% (1239/3551),10.48% (370/3530) and 7.14% (197/2717) in coastal areas,suh-coastal area and inland areas,successively (x2 =62.87,P <0.01),while those higher than UL were 5.10% (180/3530),4.86% (132/2717) and 4.14% (147/3551) in sub-coastal area,inland areas and coastal areas.In the condition of ignoring cooking loss,the mean contribution of dietary iodine intake in edible salt,all kinds of food and drinking water were 74.92%(296.03/395.13),23.85% (94.24/395.13) and 1.23% (4.86/395.13),successively; the contributions of edible salt in inland areas,sub-coastal areas and coastal areas were 83.72% (417.64/498.85),73.05% (280.88/384.50) and 66.83% (280.09/326.33),successively; the contributions of drinking water in sub-coastal areas,coastal areas and inland are
