老年人61例微量元素与认知功能分析

61 cases analysis of trace elements and cognitive function in the elderly

目的:以61例老年人为研究对象,初步研究微量元素与认知功能之间的关系。方法:在西安某社区随机抽取61例老年人,检测其微量元素,并利用简明精神状况量表(MMSE)和蒙特利尔认知评估量表(MoCA)评估认知功能。结果:老年人群中钙缺乏比例为21.3%,锌和铁缺乏的比例分别为4.9%和8.2%;以MMSE作为认知功能评估标准时,老年人认知功能损害发生率为32.95%;以MoCA作为认知功能判断标准时,该社区老年人认知功能损害发生率为44.26%;没有发现老年人血中微量元素水平与认知功能之间的相关性。结论:本次研究发现老年人微量元素以缺乏钙、锌、铁为主;老年人群中有较高的认知功能损害率。

Objective：A preliminary study of the relationship between trace elements and cognitive function.Methods：A randomly selected 61cases of the elderly community in xi＇an,blood testing its trace elements,and use the concise mental health scale（MMSE）and Montreal cognitive assessment scale（MoCA）to assess the cognitive function.Results：Lack of calcium in the elderly population was 21.3%,the proportion of zinc and iron deficiency were 4.9%and 8.2respectively;MMSE as cognitive function assessment standards,the incidence of cognitive impairment in the elderly was 32.95%;MoCA as cognitive judgment standard,the incidence of cognitive impairment in the elderly community was 44.26%;Did not find the correlation between trace elements and cognitive function.Conclusion：The study found that older people trace elements is given priority to with lack of calcium zinc iron;In the older population have a higher rate of cognitive impairment.
