这一科学陈述是关于青少年久坐行为及其与肥胖和其他心脏代谢结果的关系。久坐行为对心脏代谢健康的有害影响最明显的是基于屏幕的行为和肥胖；然而，对于其他心脏代谢结果或使用客观运动计数器或位置监测器测量久坐时间时，这种关系不太明显。屏幕时间的增加趋势令人担忧；屏幕设备的便携性以及对无限节目和在线内容的丰富访问可能会导致新的消费模式，使年轻人暴露于多种有害心脏代谢健康的途径。美国心脏协会的这份科学声明提供了关于现代年轻人特有的久坐行为及其对心脏代谢健康和肥胖的影响的最新观点。当我们反思对实践、研究和政策的影响时，就会发现了解久坐行为发生的背景的重要性。还需要在数量和质量上更准确地捕捉久坐行为的本质，特别是对于基于娱乐屏幕的设备。需要进一步的证据来更好地为公共卫生干预措施提供信息，并针对青少年特定的久坐行为制定详细的定量指南。与此同时，我们建议将电视和其他基于屏幕的娱乐设备从卧室中移走，并且在用餐时间不要使用。应鼓励日常的无设备社交互动和户外游戏。此外，应支持父母/监护人制定和执行适当的屏幕时间规定，并树立健康的屏幕行为榜样。
This scientific statement is about sedentary behavior and its relationship to obesity and other cardiometabolic outcomes in youth. A deleterious effect of sedentary behavior on cardiometabolic health is most notable for screen-based behaviors and adiposity; however, this relation is less apparent for other cardiometabolic outcomes or when sedentary time is measured with objective movement counters or position monitors. Increasing trends of screen time are concerning; the portability of screen-based devices and abundant access to unlimited programming and online content may be leading to new patterns of consumption that are exposing youth to multiple pathways harmful to cardiometabolic health. This American Heart Association scientific statement provides an updated perspective on sedentary behaviors specific to modern youth and their impact on cardiometabolic health and obesity. As we reflect on implications for practice, research, and policy, what emerges is the importance of understanding the context in which sedentary behaviors occur. There is also a need to capture the nature of sedentary behavior more accurately, both quantitatively and qualitatively, especially with respect to recreational screen-based devices. Further evidence is required to better inform public health interventions and to establish detailed quantitative guidelines on specific sedentary behaviors in youth. In the meantime, we suggest that televisions and other recreational screen-based devices be removed from bedrooms and absent during meal times. Daily device-free social interactions and outdoor play should be encouraged. In addition, parents/guardians should be supported to devise and enforce appropriate screen time regulations and to model healthy screen-based behaviors.
