Sedentary behavior is not a new topic, but trying to examine the direct links between sedentary behavior and health outcomes, independent of time spent in moderate- and vigorous-intensity physical activity, is a relatively new addition to the relationships between physical activity and health. Defining sedentary behavior as a risk factor and target for intervention opens up novel avenues for disease prevention and health promotion. The relationship between sedentary behavior and obesity is complex and not well understood, but the increased risk of disease due to sedentary behavior may be even greater in obese patients. Objective measurement of sedentary behavior is an important link in being able to understand the real effects of being sedentary, and a few measurement devices are described. Interventions targeting sedentary behavior should reduce total sedentary time, break long bouts of sitting with intermittent activity and encourage light-intensity activity throughout the day. New technologies can both measure and deliver an intervention aimed at reducing sitting time, the most common category of sedentary behavior. An optimal activity profile will include minimal amounts of sedentary behavior, in addition to regular physical activity and healthy sleep patterns.

久坐行为并不是一个新话题，但试图检查久坐行为与健康结果之间的直接联系，独立于中等和剧烈强度的身体活动所花费的时间，是对身体活动与健康之间关系的一个相对较新的补充。将久坐行为定义为风险因素和干预目标为疾病预防和健康促进开辟了新途径。久坐行为与肥胖之间的关系是复杂的，并且尚未得到很好的理解，但肥胖患者因久坐行为而增加的疾病风险可能更大。久坐行为的客观测量是能够了解久坐的真实影响的重要环节，本文介绍了一些测量设备。针对久坐行为的干预措施应减少总久坐时间，通过间歇性活动打破长时间的坐姿，并鼓励全天进行轻度强度的活动。新技术可以衡量和提供旨在减少久坐时间的干预措施，这是最常见的久坐行为类别。除了规律的身体活动和健康的睡眠模式外，最佳的活动模式还包括最少量的久坐行为。
