This study aimed to assess the relationship between leisure time spent watching television (TV) and at a computer and aggressive and violent behaviour in children and adolescents.
In this nationwide study, 14,880 school students, aged 6-18 years, were selected by cluster and stratified multi-stage sampling method from 30 provinces in Iran. The World Health Organization Global School-based Health Survey questionnaire (WHO-GSHS) was used.
Overall, 13,486 children and adolescents (50·8% boys, 75·6% urban residents) completed the study (participation rate 90·6%). The risk of physical fighting and quarrels increased by 29% (OR 1·29, 95% CI 1·19-1·40) with watching TV for >2 hr/day, by 38% (OR 1·38, 95% CI 1·21-1·57) with leisure time computer work of >2 hr/day, and by 42% (OR 1·42, 95% CI 1·28-1·58) with the total screen time of >2 hr/day. Watching TV or leisure time spent on a computer or total screen time of >2 hr/day increased the risk of bullying by 30% (OR 1·30, 95% CI 1·18-1·43), 57% (1·57, 95% CI 1·34-1·85) and 62% (OR 1·62, 95% CI 1·43-1·83). Spending >2 hr/day watching TV and total screen time increased the risk of being bullied by 12% (OR 1·12, 95% CI 1·02-1·22) and 15% (OR 1·15, 95% CI 1·02-1·28), respectively. This relationship was not statistically significant for leisure time spent on a computer (OR 1·10, 95% CI 0·9-1·27).
Prolonged leisure time spent on screen activities is associated with violent and aggressive behaviour in children and adolescents. In addition to the duration of screen time, the association is likely to be explained also by the media content.
本研究旨在评估儿童和青少年在休闲时间看电视和使用电脑与攻击性行为及暴力行为之间的关系。
在这项全国性研究中，采用整群分层多阶段抽样方法，从伊朗30个省份选取了14880名6至18岁的在校学生。使用了世界卫生组织全球学校健康调查问卷调查表（WHO - GSHS）。
总体而言，13486名儿童和青少年（50.8%为男孩，75.6%为城市居民）完成了研究（参与率90.6%）。每天看电视超过2小时，身体打架和争吵的风险增加29%（比值比1.29，95%置信区间1.19 - 1.40）；每天休闲时间使用电脑超过2小时，风险增加38%（比值比1.38，95%置信区间1.21 - 1.57）；每天总屏幕时间超过2小时，风险增加42%（比值比1.42，95%置信区间1.28 - 1.58）。每天看电视、休闲时间使用电脑或总屏幕时间超过2小时，霸凌风险分别增加30%（比值比1.30，95%置信区间1.18 - 1.43）、57%（比值比1.57，95%置信区间1.34 - 1.85）和62%（比值比1.62，95%置信区间1.43 - 1.83）。每天看电视超过2小时和总屏幕时间增加，被霸凌的风险分别增加12%（比值比1.12，95%置信区间1.02 - 1.22）和15%（比值比1.15，95%置信区间1.02 - 1.28）。对于休闲时间使用电脑，这种关系在统计学上不显著（比值比1.10，95%置信区间0.9 - 1.27）。
长时间的休闲屏幕活动与儿童和青少年的暴力及攻击性行为有关。除了屏幕时间的长短外，这种关联可能还与媒体内容有关。
