Loneliness is prevalent in adults aged ≥65 years in the United States and is associated with functional decline. The purpose of the current review was to synthesize evidence on the relationship between loneliness and functional decline using Roy's Adaptation Model as a theoretical framework. A comprehensive review of PubMed, Medline, and Embase databases was performed. Inclusion criteria were samples including adults primarily aged >60 years, peer-reviewed, published in the English language, and included a measure for loneliness and function. A total of 47 studies were analyzed. Most studies examined correlates, risk factors, and predictors of loneliness, rather than the relationship between loneliness and function. Evidence suggests there is bidirectionality in the relationship between loneliness and functional decline. Loneliness is associated with functional decline in aging via multiple possible pathways. Further studies are needed to determine causality and biological mechanisms underlying the relationship. [(4), 202-212.].
孤独在美国≥ 65 岁的成年人中很普遍，并且与功能下降有关。本综述的目的是综合使用罗伊适应模式作为理论框架来证明孤独感与功能下降之间的关系。对 PubMed、Medline 和 Embase 数据库进行了全面的回顾。纳入标准为主要年龄大于 60 岁的成年人样本、同行评审、以英文发表、并包含孤独感和功能的测量。共分析了 47 项研究。大多数研究都探讨了孤独感的相关性、危险因素和预测因素，而不是孤独感和功能之间的关系。有证据表明，孤独感和功能下降之间存在双向关系。孤独感通过多种可能的途径与老年人的功能下降有关。需要进一步的研究来确定这种关系的因果关系和生物学机制。[(4), 202-212.]。
