Ten macro elements and trace elements were directly determined in the 1992 total diet study conducted in four districts of China from north to south. The intake of these elements was evaluated. The levels of intake for seasonal variation and for different age groups were reported. The results showed that the intakes of Ca, P, K, Mg, Zn, Se and Cu were low in children. The intake of Ca, P and Zn was insufficient for adults. The intakes of other seven elements reached or approached their RDA levels, but there were big differences among the 4 districts. The relationships between intakes of Ca/P and Na/K as well as Fe and Cu and iron difficiency anemia were discussed.
在1992年对中国从北到南四个地区进行的总膳食研究中，直接测定了10种常量元素和微量元素。对这些元素的摄入量进行了评估。报告了季节变化和不同年龄组的摄入量水平。结果表明，儿童的钙、磷、钾、镁、锌、硒和铜摄入量较低。成年人的钙、磷和锌摄入量不足。其他七种元素的摄入量达到或接近其推荐膳食供给量（RDA）水平，但四个地区之间存在很大差异。讨论了钙/磷和钠/钾摄入量以及铁和铜与缺铁性贫血之间的关系。
