| 摘 要： | 目的了解四川省农村≥65岁老年人膳食微量元素摄入情况和食物来源。方法采集当地粮食、蔬菜等食物样品,测定其中8种微量元素的含量,结合膳食问卷调查结果计算个体日常膳食微量元素摄入情况。结果114份样品中各种微量元素的检出率均80%;人群膳食Se、Ca、Cu、Fe、Zn每天平均摄入量分别为(14.325±8.914)μg,(333.407±269.785),(3.109±4.890),(18.179±27.515),(6.902±3.493)mg,其中Se、Ca、Cu、Fe和Zn的摄入量均有50%的老年人低于日推荐摄入量或日适宜摄入量;对人体有毒性作用的Cd和Pb周摄入量超过WHO推荐的周允许摄入量的老年人分别有439和154人;除男性膳食Cu日摄入量明显高于女性(P0.001)外,其他膳食微量元素摄入情况性别差异无统计学意义。结论四川省农村老年人膳食必需微量元素摄入量普遍不足,对人体有毒性作用的Cd和Pb摄入量严重超标。
