很少有研究试图描述儿童久坐不动的行为模式，并研究这些行为模式与身体活动模式的关系。来自美国和英国的2,494名11-15岁的青少年完成了一份身体活动清单。久坐行为之间的低相关性表明，青少年久坐是多方面的，不能用任何一种行为（如看电视）来准确表示。聚类分析确定了三组年轻人，按久坐行为和体育活动的水平和类型进行区分。身体活动和久坐不动的行为不是同一枚硬币的两面。进一步的研究应该检查与久坐行为相关的健康相关结果，以及年轻人这些行为的可改变的决定因素。
Few studies have attempted to describe patterns of sedentary behavior among children and examine how these relate to patterns of physical activity. A group of 2,494 youth aged 11-15 years from the USA and UK completed a physical activity checklist. Low intercorrelations between sedentary behaviors suggest youth sedentariness is multifaceted and cannot be represented accurately by any one behavior such as TV viewing. Cluster analysis identified three groups of young people, differentiated by the level and type of sedentary behavior and physical activity. Physical activity and sedentary behavior are not two sides of the same coin. Further study should examine the health-related outcomes associated with sedentary behavior and the modifiable determinants of these behaviors among young people.
