摘　　要：目的:营养不良和轻度认知功能障碍的关系仍不清楚。本研究观察老年轻度认知功能障碍住院患者营养不良的患病率。方法:对323名老年住院患者进行详细的评估,包括躯体健康、认知功能、情感和社会功能;并用微型营养评估量表评定营养状况。根据神经心理学评估,认知功能分为三个水平:正常、轻度认知功能障碍和痴呆。结果:根据微型营养评估量表的评估,39.93%的研究对象营养状况为良好,34.98%为可疑营养不良,25.07%为营养不良。与认知功能正常的住院患者相比,轻度认知功能障碍和痴呆患者营养状况良好的比例明显降低,并且营养不良的风险明显升高。结论:在痴呆和轻度认知功能障碍者住院患者中营养不良的患病率明显增高。Objective：To explore the relationship between the nutritional status and the preclinical phase of dementia in the elderly.The aim of this study was to evaluate the prevalence of malnutrition in older patients with mild cognitive impairment.Methods：A total of 323 hospitalized elderly patients underwent the comprehensive geriatric assessment to evaluate medical,cognitive,affective and social aspects.Nutritional status was assessed by using the mini-nutritional assessment.The cognitive function was categorized into three levels-normal cognition,mild cognitive impairment and dementia according to the neuropsychological evaluation.Results： According to the mini-nutritional assessment classification,39.93% of the sample study was assessed as well nourished,34.98% at risk of malnutrition and 25.07% as malnourished.Patients with mild cognitive impairment and dementia had significantly lower frequency of well nourished and higher frequency of at risk of malnutrition or malnourished than patients with normal cognition.Conclusions： Malnutrition is prevalent in hospitalized elderly patients with dementia and in those with mild cognitive impairment.
