: New evidence suggests that reductions in sedentary behavior may increase physical activity and improve health. These findings point to new behavioral targets for intervention and new ways to think about intervening to increase overall physical activity in the population. This report provides a knowledge update reflecting the rapid accumulation of new evidence related to sedentary behavior and health among adults. Recent observational studies suggest that leveraging the time-inverse relationship between sedentary and active behaviors by replacing sitting with standing, light- or moderate-intensity activity can have important health benefits, particularly among less active adults. Clinical studies are providing evidence of the probable physiologic mechanisms underlying these associations, as well as insights into the cardiometabolic impact of breaking up and reducing sedentary behavior. In contrast to the well-established behavioral theories that guide the development and dissemination of evidence-based interventions to increase moderate- to vigorous-intensity physical activity, much less is known about how to reduce sedentary time to increase daily activities. It has become clear that the environmental, social, and individual level determinants for sedentary time are distinct from those linked to the adoption and maintenance of moderate- to vigorous-intensity physical activity. As a result, novel intervention strategies that focus on sitting and lower-intensity activities by leveraging the surrounding environment (e.g., workplace, school, and home) as well as individual-level cues and habits of sedentary behavior are being tested to increase the potency of interventions designed to increase overall physical activity. Herein we summarize the solutions-oriented research across the behavioral research framework, with a focus on highlighting areas of synergy across disciplines and identifying gaps for future research.
新证据表明，减少久坐行为可能会增加身体活动并改善健康状况。这些研究结果指出了新的行为干预目标，以及思考如何进行干预以增加人群总体身体活动的新方法。本报告提供了一份知识更新内容，反映了与成年人久坐行为和健康相关的新证据的迅速积累。最近的观察性研究表明，通过用站立、轻度或中度强度活动替代久坐来利用久坐行为和活跃行为之间的时间反相关关系，可能会带来重要的健康益处，尤其是在活动较少的成年人中。临床研究正在为这些关联背后可能的生理机制提供证据，同时也深入了解打破和减少久坐行为对心脏代谢的影响。与指导增加中度至剧烈强度身体活动的循证干预措施的制定和推广的成熟行为理论不同，对于如何减少久坐时间以增加日常活动的了解要少得多。很明显，久坐时间的环境、社会和个人层面的决定因素与那些与采用和维持中度至剧烈强度身体活动相关的因素不同。因此，正在测试通过利用周围环境（如工作场所、学校和家庭）以及久坐行为的个人层面线索和习惯来专注于坐姿和低强度活动的新型干预策略，以提高旨在增加总体身体活动的干预措施的效力。在此，我们总结了行为研究框架内以解决方案为导向的研究，重点是突出各学科之间的协同领域，并确定未来研究的差距。
