Abstract

Abstract: Objective To describe the distribution of screen time in adolescents,and to examine the influence of screen time in the study days or weekends on physical and psychological sub-health. Methods A total of 3 477 students in an ordinary high school in Anhui province were surveyed from October to November 2015.General demographic data and screen time were collected,and the Multidimensional Sub-health Assessment Questionnaire of Adolescents(MSQA) was used to assess physical and psychological health.The difference on the rate of physical and psychological sub-health between various screen time groups was analyzed by chi-square test.Logistic regression model was used to analyze the effect of screen time and physical and psychological sub-health. Results Totally 605(17.4%) adolescents had screen time on study days and 2 126(61.1%) on weekends over 2 hours per day.And 958 adolescents(27.6%) suffered from physical sub-health and 794 adolescents(22.8%) with psychological sub-health in this survey.Multivariate Logistic regression analysis showed that screen time over 2 h/d on study days(physical sub-health OR=1.25,95%CI:1.02-1.53; psychological sub-health OR=1.48,95%CI:1.19-1.82),screen time over 2 h/d on weekends(physical sub-health OR=1.44,95%CI:1.22-1.69; psychological sub-health OR=1.72,95%CI:1.44-2.05),and screen time over 2 h/d both on study days and weekends(physical sub-health OR=1.63,95%CI:1.29-2.70; psychological sub-health OR=2.13,95%CI:1.65-2.74) will increase the risk of the physical and psychological sub-health in adolescents. Conclusions Longer screen time will increase the risk of physical and psychological sub-health in adolescents.And it may be helpful to improve physical and psychological health by limiting the screen time.

摘要： 目的了解中学生视屏时间分布情况,分析中学生学习日或周末视屏时间对身心亚健康的影响。方法 2015年10—11月抽取安徽省某市普通初高中3 477名在校学生进行问卷调查,收集一般人口统计学信息和视屏时间,并利用《青少年亚健康多维评定问卷》评价身心亚健康状况。采用χ²检验比较不同视屏时间组间身心亚健康状态检出率的差异,建立Logistic 回归模型分析中学生视屏时间对身心亚健康的影响。结果学习日和周末视屏时间＞2 h/d者分别为605人(17.4%)和2 126人(61.1%),躯体亚健康状态者958人(27.6%),心理亚健康状态者794人(22.8%)。多因素Logistic回归分析显示,学习日视屏时间＞2 h/d(OR=1.25,95%CI:1.02~1.53;OR=1.48,95%CI:1.19~1.82),周末视屏时间＞2 h/d(OR=1.44,95%CI:1.22~1.69;OR=1.72,95%CI:1.44~2.05),学习日和周末视屏时间均＞2 h/d(OR=1.63,95%CI:1.29~2.70;OR=2.13,95%CI:1.65~2.74)会显著增加中学生躯体和心理亚健康的风险。结论较长视屏时间会增加中学生身心亚健康风险,控制视屏时间有助于中学生身心健康的促进。
