24-hour Movement Behaviors: a New Direction for the Study of Factors Affecting Health of the Elderly

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.
