目的：考虑兼职工作对学生剩余时间的影响，确定青少年在体育活动上花费的时间与他们在不同的久坐活动上花费的时间之间是否存在关系：看电视、玩电子游戏、使用电脑、做作业和阅读。设计：横断面队列设计。参与者和环境：743名高中生，分别来自市内2所公立学校和1所私立学校。方法：学生们完成了一份自我管理的调查问卷，包括体力活动的时间、久坐的时间、肌肉骨骼疼痛和社会心理问题，并测量了身高和体重。主要结局指标：身体活动水平（低、中、高）。结果：低、中体力活动组女生多于男生，高体力活动组男生多于女生。有序逻辑回归显示，“生产性久坐行为”（阅读或做作业和在电脑上工作）的时间增加与体力活动增加有关（优势比，1.7-1,95%置信区间，1.2-2.4），工作时间也与体力活动增加有关（优势比，13；95%置信区间，1.2-1.4）。看电视和玩电子游戏的时间与体力活动的减少无关。结论：体育活动与看电视或玩电子游戏没有负相关，但与生产性久坐行为和兼职工作呈正相关。有些学生似乎比其他人更善于管理自己的时间。未来的研究应该探索学生管理时间的能力，并确定哪些特征有助于更好地管理时间。
Objective: To determine whether there is a relationship between the time adolescents spend in physical activity and time they spend in different sedentary pursuits: watching television, playing video games, working on computers, doing homework, and reading, taking into account the effect of part-time work on students' residual time.Design: Cross-sectional cohort design.Participants and Setting: Seven hundred forty-three high school students from 2 inner-city public schools and 1 private school.Methods: Students completed a self-administered questionnaire that addressed time spent in physical activity, time spent in sedentary pursuits, musculoskeletal pain, and psychosocial issues and were also measured for height and weight.Main Outcome Measure: Level of physical activity (low, moderate, high).Results: There were more girls than boys in the low and moderate physical activity groups and more boys than girls in the high activity group. Ordinal logistic regression showed that increased time spent in "productive sedentary behavior" (reading or doing homework and working on computers) was associated with increased physical activity (odds ratio, 1.7-1 95% confidence interval, 1.2-2.4), as was time spent working (odds ratio, 13;95%confidence interval, 1.2-1.4). Time spent watching television and playing video games was not associated with decreased physical activity.Conclusions: Physical activity was not inversely associated with watching television or playing video games, but was positively associated with productive sedentary behavior and part-time work. Some students appear capable of managing their time better than others. Future studies should explore the ability of students to manage their time and also determine what characteristics are conducive to better time management.
