Sedentary behaviors refer to any waking activity characterized by an energy expenditure ≤ 1.5 metabolic equivalent and a sitting or lying posture. Recent epidemiological data reported that in North America and Europe, citizens spend between 8 and 11 hours sitting per day. Sedentary behaviors and physical activity can coexist in the same person. It is possible to spend a lot of time sitting each day while completing recommendations for regular physical activity. Adverse health effects of sedentary behaviors are in part independent of the physical activity level. The physiological implications associated with sedentary behaviors are mainly metabolic. Regulary interrupting the sedentary behavior has favorable effects on health, regardless the total time spent sitting. Many interventional perspectives for reducing sedentary behaviors in France can be envisaged. Some countries have already launched interesting large-scale prevention programs.
久坐行为是指任何以能量消耗≤1.5代谢当量以及坐姿或躺姿为特征的清醒活动。最近的流行病学数据显示，在北美和欧洲，市民每天坐着的时间在8到11小时之间。久坐行为和身体活动可以在同一个人身上并存。一个人有可能在每天花大量时间坐着的同时，还能完成定期身体活动的建议。久坐行为对健康的不良影响部分独立于身体活动水平。与久坐行为相关的生理影响主要是代谢方面的。无论久坐的总时长如何，定期中断久坐行为对健康都有有利影响。在法国，可以设想出许多减少久坐行为的干预措施。一些国家已经启动了有趣的大规模预防项目。
