摘　　要：通过测定混合膳食中１０种常量和微量元素含量，评价中国南、北四大地区人群每日膳食中常量和微量元素的摄入状况，并报道了膳食中各元素摄入量以及不同年龄组和春秋两季膳食中各元素摄入量的变化情况。结果表明：儿童膳食中不同程度地存在钙、磷、钾、镁、锌、硒和铜的偏低；成人膳食中钙、钾和锌摄入明显不足，其余７种元素均接近或达到推荐供给量水平，但地区差异较大。本文对钙磷比，钾钠比以及铁和铜与缺铁性贫血之间的关系进行了讨论。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 disucssed.
