【摘要】 近年来我国不断推进全人群的健康管理工作，对老年人衰弱的研究从单一维度的生理衰弱逐渐转向社会衰弱，拓宽了医学领域的研究视角。社会衰弱指老年人在生命周期中逐渐失去或已经失去满足一种或多种基本社会需求的重要社会资源、行为、活动及自我管理能力，限制了老年人的日常活动和社会参与，可能导致孤独感、无助感和焦虑等负面情绪的产生，严重影响其生存质量，给家庭和社会带来巨大的压力与挑战，现已成为老年保健医学的重要研究方向。但目前对社会衰弱的研究尚处于探索阶段，相关研究间存在争议。因此本研究整理国内外有关老年人社会衰弱的相关内容，详细概述了社会衰弱的概念，介绍了蒂尔堡衰弱指数、HALFT量表、社会脆弱性指数3个主要评估工具，归纳了社会人口学因素、躯体健康因素、社会心理因素以及生活方式4个方面的影响因素，并整理了有效的干预策略。研究发现相较于单独运动和营养干预，社会支持以及运动联合营养对老年人社会衰弱的干预效果较为显著，为临床重视社会衰弱的早期管理及降低老年人社会衰弱的发生提供参考，对提高老年人生活质量意义重大。更多还原
