A positive association between time spent on sedentary screen-based activities and physical complaints has been reported, but the cumulative association between different types of screen-based activities and physical complaints has not been examined thoroughly.
The cross-sectional association between screen-based activity and physical complaints (backache and headache) among students was examined in a sample of 31022 adolescents from Denmark, Sweden, Norway, Finland, Iceland and Greenland, as part of the Health behaviour in school-aged children 2005/06 (HBSC) study. Daily hours spent on screen-based activities and levels of physical complaints were assessed using self-reports.
Logistic regression analysis indicated that computer use, computer gaming and TV viewing contributed uniquely to prediction of weekly backache and headache. The magnitude of associations was consistent across types of screen based activities, and across gender.
The observed associations indicate that time spent on screen-based activity is a contributing factor to physical complaints among young people, and that effects accumulate across different types of screen-based activities.
已有研究报告指出，花在久坐的基于屏幕的活动上的时间与身体抱怨之间存在正相关关系，但不同类型的基于屏幕的活动与身体抱怨之间的累积关联尚未得到充分研究。
丹麦、瑞典、挪威、芬兰、冰岛和格陵兰的 31022 名青少年参与了健康行为在学校儿童研究 2005/06 （HBSC）的一项研究，该研究以横断面设计调查了基于屏幕的活动与学生身体抱怨（背痛和头痛）之间的关联。使用自我报告评估基于屏幕的活动的日常时间和身体抱怨的程度。
逻辑回归分析表明，计算机使用、计算机游戏和电视观看对每周背痛和头痛的预测具有独特的贡献。不同类型的基于屏幕的活动和性别之间的关联强度一致。
观察到的关联表明，花在基于屏幕的活动上的时间是年轻人身体抱怨的一个促成因素，并且这种影响会在不同类型的基于屏幕的活动中累积。
