[目的]分析静态行为与屏前行为、轻度体力活动、中重度体力活动，以及与学生营养状况的关系。[方法]2011年采用多阶段抽样法抽取上海市3个区3所中学共10个班级的学生自行填写的调查表，对学生上学日和周末的整日各个活动进行分类汇总和分析。对数据进行描述性分析、相关性分析和Kruskal-Wallis检验。[结果]周末调查对象的静态行为是每天389．19 min，屏前行为的时间是每天122．93 min，均超过上学日的3倍。青少年的静态行为时间与中重度体力活动无关，与轻度体力活动有关。肥胖组、超重组、体重正常组、较低体重组和营养不良组周末的屏前时间均值的差异有统计学意义。[结论]青少年课余时间的体力活动不足，屏前行为可能与青少年不良的营养状况有关。

[Objective] To investigate and analyse the related factors of static behavior among ado-lescents , such as screen time , mild physical activity , moderate and vigorous physical activity , and nutri-tional status. [ Methods] In 2011, multistage sampling was done from 10 classes of three middle schools in three districts in Shanghai;the students filled the questionnaire on their own which recorded all of the activities of one school day and one weekend day .The data was analyzed by general describing analysis , correlation analysis, and Kruskal-Wallis test. [Results] The static time in weekend was 389.19 mi-nutes per day , the screen time was 122 .93 minutes per day , and both were over three times those on one school day .The static time was not related to moderate and vigorous physical activity , but was related to mild physical activity .The difference in mean time before the screen at weekend was statistically significant between obesity group , overweight group , normal group , low weight group and malnutrition group . [ Con-clusion] Adolescents lacked adequate physical activities in their spare time , and behavior before the screen might be related to their poor nutrition status .
