【摘要】 目的探讨称重法和化学分析法评估人群矿物质摄入量的差异和相关性。方法同时使用称重法和化学分析法对89名上海市居民进行膳食调查,并对两种调查方法测得的钙、镁、铁、锌、铜、锰摄入量进行比较分析。结果称重法调查的6种矿物质元素的摄入量高于化学分析法(P<0.05),称重法调查的平均每天钙、镁、铁、锌、铜、锰摄入量比化学分析法分别高20.9%、67.4%、19.5%、84.4%、46.7%和33.3%;称重法与化学分析法测得的钙、镁、铁、锌、铜、锰摄入量均呈显著正相关(P<0.01),相关系数分别为0.571、0.672、0.521、0.524、0.538和0.691。结论称重法测得的人群膳食矿物质摄入量高于化学分析法。更多还原

【Abstract】 Objective To explore the differences and correlation between mineral elements intakes investigated by weighing dietary record and duplicated diet. Methods Eighty-nine Shanghai citizens were performed dietary survey by weighing dietary record and duplicated diet.The intakes of Ca,Mg,Fe,Zn,Cu and Mn investigated by the two methods were compared and analysed. Results Daily dietary Ca,Mg,Fe,Zn,Cu and Mn intakes were significantly higher by weighing dietary record than the result of duplicated diet(P<0.05),and the proportion of over-report by weighing dietary record were 20.9%,67.4%,19.5%,84.4%,46.7% and 33.3%,respectively.There was a significantly positive correlation between the results of weighing dietary record and duplicated diet(P<0.01),and the correlation coefficients were 0.571,0.672,0.521,0.524,0.538,and 0.691,respectively. Conclusion Mineral elements intakes investigated by weighing dietary record were higher than those investigated by duplicated diet更多还原
