24-hour movement behaviors include physical activity, sedentary behavior and sleep. Domestic and foreign studies have found that the elderly generally have problems of low physical activity, sedentary behavior and insufficient sleep. Rational allocation of 24-hour movement behaviors has been demonstrated to be an important measure to improve adverse health outcomes in older adults, but the relevant research on 24-hour movement behaviors of the elderly is still in the exploratory stage. This paper reviews the concept, theoretical development and analytical methods of 24-hour movement behaviors and its relationship with adverse health outcomes in the elderly. In the future, relevant studies should be actively carried out to deeply explore and quantify the impact of 24-hour movement behaviors on health, develop a combination of 24-hour movement behaviors that can exert the maximum health benefits of the elderly, and develop accurate assessment tools, so as to promote active and healthy aging.

24 h活动行为包括身体活动、久坐行为及睡眠，国内外研究发现老年人普遍存在身体活动少、久坐、睡眠不足的问题，已有研究证明合理分配24 h活动行为是改善老年人不良健康结局的重要措施，但目前对于老年人24 h活动行为的相关研究仍处于探索阶段。本文结合现有的研究从24 h活动行为的概念、理论发展、分析方法以及其与老年人不良健康结局的关系进行综述。未来需要积极开展相关研究，深入探讨并量化24 h活动行为对老年人健康产生的影响，形成能够发挥老年人最大健康效益的24 h活动行为组合，开发准确的评估工具，以促进积极老龄化和健康老龄化。
