Most adolescents spend excessive screen time (with television viewing, computer/console gaming, discussion forums/chatting online, internet surfing, doing homework, and electronic mails) which may impact the occurring of various types of school and out-of-school injuries. We assessed their associations and potential confounding factors among 1559 middle-school students from north-eastern France (mean age=13.5 ± 1.3). Participants completed a questionnaire including socioeconomic features, daily screen time for various screen-based activities (coded 1=<2, 2 = 2-4, 3=≥5 h; daily-total-screen time level (TDST) was defined as their sum, categorized into <7/7-11/≥12), various injury types during the school-year, behavior and health difficulties (BHDs; alcohol/tobacco/cannabis/other illicit drugs use, suffered physical/verbal violence, sexual abuse, poor family-peer support, sleep difficulty, depressive symptoms, suicide attempt, and time at onset). Most subjects had TDST≥7 (82.3 %). There were dose-effect associations of TDST with school-physical/sports training, school-free-time, out-of-school-sports, and single/repeated injuries (sex-age-adjusted odds ratio reaching 4.45). BHDs explained up to 39 % of these associations. The frequency of subjects without various BHDs decreased with age since age 10 more quickly among the participants with both TDST≥7 and injury than among the others. Our findings may inform health care providers, parents, schools, and public policy that reducing elevated screen time is efficient to prevent injuries and BHDs among adolescents.
大多数青少年花过多的屏幕时间（包括看电视、玩电脑/游戏机、使用讨论论坛/在线聊天、上网、做作业和发电子邮件），这可能会影响各种校内和校外伤害的发生。我们评估了这些关联及其在法国东北部 1559 名中学生中的潜在混杂因素（平均年龄=13.5±1.3）。参与者完成了一份问卷，包括社会经济特征、各种基于屏幕的活动的日常屏幕时间（编码 1=<2，2=2-4，3=≥5 小时；每日总屏幕时间水平（TDST）定义为他们的总和，分为<7/7-11/>12），学年期间的各种伤害类型，行为和健康困难（BHD；酒精/烟草/大麻/其他非法药物使用，遭受身体/言语暴力，性虐待，家庭-同伴支持差，睡眠困难，抑郁症状，自杀企图和发病时间）。大多数受试者的 TDST≥7（82.3%）。TDST 与学校体育训练、学校闲暇时间、校外体育和单次/重复伤害之间存在剂量效应关联（性别年龄调整的优势比达到 4.45）。BHDs 解释了这些关联的高达 39%。从 10 岁开始，没有各种 BHDs 的受试者的频率随着年龄的增长而迅速下降，而在 TDST≥7 和受伤的参与者中比在其他参与者中下降得更快。我们的研究结果可能为卫生保健提供者、家长、学校和公共政策提供信息，即减少过度的屏幕时间可以有效地预防青少年的伤害和 BHDs。
