摘　　要：目的了解初中生屏前行为与特质焦虑的关系,为开展学生行为干预提供依据。方法采取二阶段随机整群抽样的方法,抽取上海市9所中学六~九年级的4 196名学生为研究对象,并采用二分类Logistic回归分析,分析过长屏前行为与中学生特质性焦虑的关系。结果学生在1周内平均每天的屏前时间是2.68 h,男生（2.92 h）高于女生（2.47 h）（t=6.508,P=0.000）,不同年龄组间差异有统计学意义（F=4.634,P=0.001）。51.5%的调查对象平均每天屏前时间≥2 h。在屏前时间≥3 h的情况下,学习压力、不良环境影响、自卑倾向和人际困扰与过长屏前行为有关（OR值分别为1.014,1.030,0.979,1.040）。结论过长的屏前行为在青少年中普遍存在,与青少年的焦虑有关,应在行为干预中考虑心理因素的影响。Objective To understand the association between screen time and trait anxiety among middle school students in Shanghai, and to provide evidence for intervention. Methods A Total of 4 196 middle schools students aged 9 to 16 years and their parents in Shanghai were recruited by a two-stage sampling method in 2011. A structured questionnaire was used to collect in- formation on screen time and related risk factors. Average screen time per week was calculated. Logistic regression models were de- veloped to determine the contribution of screen time to trait anxiety. Results The average screen time per week was 2.68 h, boys （2.92 h ） was higher than the girls （ 2.47 h ）.About 51.5% students had excessive screen time. Academic pressure, adverse envi- ronment, inferiority complex and interpersonal problems were related to excessive screen time. Conclusion The excessive screen time was common among adolescents in Shanghai. Mental health promotion should be considered in the specific intervention.
