The aim of this study was to analyze the relationship between TV and computer use, study time, and physical activity, with regard to gender, school, and weekday/weekend. Adolescents (N = 1,609; M age = 14.5 yr., SD = 1.3) reported on physical activity, sedentary behavior, their parents' employment, and environmental factors. The relationship between PA and screen media behaviors was negative on weekdays, while no relationship was found at weekends. Only 30.7% of adolescents met the screen media guidelines on weekdays and 14.6% at weekends. Girls spent more time on study, only showing a positive relationship with physical activity on weekdays. Each type of sedentary behavior has different correlates for weekdays and weekends.
本研究的目的是分析在性别、学校以及工作日/周末方面，看电视和使用电脑的情况、学习时间与身体活动之间的关系。青少年（N = 1609；平均年龄 = 14.5岁，标准差 = 1.3）报告了他们的身体活动、久坐行为、父母的职业以及环境因素。在工作日，身体活动与屏幕媒体行为之间呈负相关，而在周末未发现相关性。只有30.7%的青少年在工作日符合屏幕媒体使用指南，在周末这一比例为14.6%。女孩花在学习上的时间更多，仅在工作日与身体活动呈正相关。每种久坐行为在工作日和周末都有不同的关联因素。
