在西方年轻人中，屏幕时间与健康指标呈负相关，但对中国年轻人的这种关系知之甚少。武汉市初中生和高中生中国于2016年春夏完成问卷调查，调查对象包括人口统计学、健康行为和自我知觉。线性和逻辑回归分析被用来确定，在调整协变量后，屏幕时间是否与身体质量指数(BMI)、饮食行为、平均每晚睡眠时间、体力活动(PA)、学习成绩和心理状态有关。在上学的日子里看电视与学业成绩、PA、焦虑和生活满意度呈负相关。非上学时间看电视与睡眠时间呈正相关。玩电子游戏与晚上吃零食和较少吃早餐呈正相关，与睡眠时间和自尊呈负相关。在非在校期间接收电子新闻和学习材料与PA负相关，但在在校期间与焦虑正相关。使用社交网站与学习成绩呈负相关，但与BMI z-Score、PA和焦虑呈正相关。青少年的屏幕时间与不健康的行为和不良的心理状态有关，这可能会导致生活质量下降。
Screen time is negatively associated with markers of health in western youth, but very little is known about these relationships in Chinese youth. Middle-school and high-school students (n = 2625) in Wuhan, China, completed questionnaires assessing demographics, health behaviors, and self-perceptions in spring/summer 2016. Linear and logistic regression analyses were conducted to determine whether, after adjustment for covariates, screen time was associated with body mass index (BMI), eating behaviors, average nightly hours of sleep, physical activity (PA), academic performance, and psychological states. Watching television on school days was negatively associated with academic performance, PA, anxiety, and life satisfaction. Television viewing on non-school days was positively associated with sleep duration. Playing electronic games was positively associated with snacking at night and less frequently eating breakfast, and negatively associated with sleep duration and self-esteem. Receiving electronic news and study materials on non-school days was negatively associated with PA, but on school days, was positively associated with anxiety. Using social networking sites was negatively associated with academic performance, but positively associated with BMI z-score, PA and anxiety. Screen time in adolescents is associated with unhealthy behaviors and undesirable psychological states that can contribute to poor quality of life.
