Dietary patterns may be related to quality of life (QoL) of older adults, although evidence from literature is conflicting. The demographic shifts toward ageing populations in many countries increases the importance of understanding the relationship between diet and QoL in older adults. This review was designed to investigate associations between dietary patterns and QoL in older adults. The systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eight electronic databases were searched to identify articles published in English from January 1975 to March 2018 that investigated associations between dietary patterns and QoL in older adults. Relevant studies were identified based on set inclusion and exclusion criteria, data were extracted and analysed to examine the relationships and possible implications for public health recommendations. The systematic review included 15 articles (One randomized control trial, six prospective cohorts and eight cross sectional). The studies looked at correlations between different dietary patterns and/or adherence to particular dietary patterns and self-reported QoL or self-rated health status. Excluding two studies which showed no significant association, healthy dietary patterns were associated with better self-rated health and QoL in one or more domains, and adherence to healthy dietary patterns like the Mediterranean diet were significantly associated with improvement in at least one of the QoL domains.
饮食模式可能与老年人的生活质量（QoL）有关，但文献中的证据存在矛盾。许多国家的人口向老龄化转变，这使得理解老年人饮食与 QoL 之间的关系变得尤为重要。本综述旨在调查饮食模式与老年人生活质量之间的关系。该系统评价遵循系统评价和荟萃分析的首选报告项目（PRISMA）指南。共检索了 8 个电子数据库，以确定自 1975 年 1 月至 2018 年 3 月发表的、调查老年人饮食模式与 QoL 之间关系的英文文章。根据设定的纳入和排除标准确定相关研究，提取和分析数据，以检验相关性以及对公共卫生建议的可能影响。系统评价纳入了 15 篇文章（1 项随机对照试验、6 项前瞻性队列研究和 8 项横断面研究）。这些研究观察了不同饮食模式之间的相关性和/或对特定饮食模式的依从性与自我报告的 QoL 或自我评定的健康状况之间的关系。排除了两项没有显著相关性的研究，一项或多项领域的健康饮食模式与更好的自我评定健康和 QoL 相关，而坚持健康的饮食模式，如地中海饮食，与至少一个 QoL 领域的改善显著相关。
