有人建议将1500kcal(6276kJ)作为每日摄入的最低能量标准来供给老年人充足的微量元素。这个参考值曾用来评价老年人的能量摄入是否充足。本文的目的是以参与欧洲营养和老年一致行为调查(SENECA)研究的老年人为研究对象。以评价怎样的能量标准才能符合大部分老年人微量元素的需要。对象与方法本文资料来自SENECA的随访研究。从参与该研究的9个国家中选择老年男性486名,女性519名,平均年龄77.2(74～79)岁。通过饮食回顾法获得饮食资料,用当地饮食成分表计算营养素的摄入情况,尤其是与能量摄入有关的铁,VitB_1、VitB_(12)和VitB_6。用荷兰最低需要量作为微量元素摄入不足的参考值,并与美国推荐的饮食供给量(RDA)的2/3作比较。
It is suggested that 1500 kcal (6276 kJ) be used as the minimum energy standard for daily intake to provide sufficient amounts of trace elements to the elderly. This reference has been used to assess the adequacy of energy intake in the elderly. The purpose of this article is to examine the elderly who participated in the SENECA study. To assess what kind of energy standards to meet the needs of most elderly trace elements. Subjects and Methods The data in this paper is from the follow-up study of SENECA. 486 elderly men and 519 women were selected from the 9 countries involved in the study, with an average age of 77.2 (74-79) years. Dietary information was obtained through a dietary review and nutrient intakes were calculated using a local diet table, specifically iron, VitB_1, VitB_ (12) and VitB_6 associated with energy intake. Use the minimum Dutch requirement as a reference for inadequate intake of trace elements and compare with 2/3 of the recommended U.S. dietary supply (RDA).
