背景：几项以人群为基础的研究表明，老年人的饮食、生活方式和认知之间的关系。然而，这些研究得出的结论并不一致。方法：对894名50岁及以上的中国老年人进行横断面研究。采用蒙特利尔认知评估(MoCA)测验对受试者的认知功能进行评估。人口统计学特征和生活方式通过问卷收集。结果：轻度认知损害(MCI)患者具有年龄大、文化程度低的特点(P<；0.01)。MCI患者的坚果和食用油摄入量低于正常人(P<；0.05)。水果和蔬菜的摄入有利于老年人的定向、命名和注意力能力(P<；0.05)。饮用果蔬汁有利于提高提取能力(P<；0.01)。经常阅读、有家政习惯的受试者认知能力较好(P<；0.01)。结论：坚果、蔬菜、水果丰富的饮食可降低认知损害的风险。阅读和家政有助于保持老年人的健康认知。(C)2015爱思唯尔爱尔兰有限公司。保留所有权利。
Background: The relationship between diet, lifestyle and cognition of old adults has been indicated in several population-based studies. However, the conclusions derived from these studies are inconsistent.Methods: A cross-sectional study was carried out in 894 old Chinese adults aged 50 and above. Cognitive function of the participants was measured by using Montreal Cognitive Assessment (MoCA) test. Demographic characteristics and lifestyle was collected with a questionnaire. A semi-quantified FFQ method was used for dietary intake survey.Results: Comparing with normal subjects, mild cognition impairment (MCI) patients were characterized as old age and lower education (P < 0.01). The nuts and cooking oil intake of MCI patients was less than the normal subjects (P < 0.05). Fruit and vegetable intake will benefit orientation, name and attention ability in the elderly (P < 0.05). Fruit and vegetable juice drinking will benefit abstraction ability (P < 0.01). Subjects with regular reading and housekeeping habit had better cognition (P < 0.01).Conclusions: Nuts, vegetables and fruit-rich diet might decrease the risk of cognition impairment. Reading and housekeeping help to maintain healthy cognition in the elderly. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
