屏幕行为在年轻人中非常普遍,过度使用屏幕可能会对身心健康构成风险。了解年轻人积累屏幕时间的时间和社交环境可能有助于告知干预措施的设计以限制屏幕使用。这项研究旨在描述青少年基于屏幕的行为的昼夜模式,并在工作日和周末检查社交环境与这些行为的关联。
时间使用日记数据来自千年队列研究的第六波(2015/2016),参与者在14岁时进行。结果变量是电子游戏/应用程序,看电视,电话和电子邮件/短信,访问社交网站和互联网浏览。社会环境被归类为只有一个人,只有父母,只有朋友,只有兄弟姐妹,只有父母和兄弟姐妹。使用多水平多变量逻辑回归来检查社交环境与屏幕活动之间的关联。
在工作日/周末,男女在每小时20:00至22:00之间,花在看电视上的时间最多,高峰为20分钟。在工作日的下午/晚上和周末的下午/傍晚,为男孩使用电子游戏/应用程序和为女孩使用社交网站的时间最大。屏幕活动主要是单独进行的,除了看电视。与孤独相比,与家庭成员在一起与(赔率比(95%信心间隔))在整个星期中男孩和女孩看电视的时间更长(工作日:男孩,2.84(2.59,3.11);女孩,2.25(2.09,2.43);周末:男孩,4.40(4.16,4.67);女孩,5.02(4.77,5.27))。与朋友在一起与更多的时间在周末使用电子游戏有关男女(男孩,3.31(3.12,3.51);女孩,3.13(2.67,3.67))。
屏幕行为的减少可能是一整天的目标,但应该对不同的背景敏感。家庭成员,朋友,青少年本身可能是行为改变干预的重要目标群体。未来的研究,以解决社会环境之间复杂的相互作用,屏幕行为的内容和质量将有助于行为改变干预措施的设计。
Screen behaviours are highly prevalent in young people and excessive screen use may pose a risk to physical and mental health. Understanding the timing and social settings in which young people accumulate screen time may help to inform the design of interventions to limit screen use. This
study aimed to describe diurnal patterns in adolescents\' screen-based behaviours and examine the association of social context with these behaviours on weekdays and weekend days.
Time use diary data are from the sixth wave (2015/2016) of the Millennium Cohort
Study, conducted when participants were aged 14 years. Outcome variables were electronic games/Apps, TV-viewing, phone calls and emails/texts, visiting social networking sites and internet browsing. Social context was categorised as alone only, parents only, friends only, siblings only, parents and siblings only. Multilevel multivariable logistic regression was used to examine the association between social contexts and screen activities.
Time spent in TV-viewing was greatest in the evening with a peak of 20 min in every hour between 20:00 and 22:00 in both sexes on weekdays/weekend days. Time spent using electronic games/Apps for boys and social network sites for girls was greatest in the afternoon/evening on weekdays and early afternoon/late evening on weekend days. Screen activities were mainly undertaken alone, except for TV-viewing. Compared to being alone, being with family members was associated with (Odds Ratio (95% Confidence Interval)) more time in TV-viewing in both boys and girls throughout the week (Weekdays: Boys, 2.84 (2.59, 3.11); Girls, 2.25 (2.09, 2.43); Weekend days: Boys, 4.40 (4.16, 4.67); Girls, 5.02 (4.77, 5.27)). Being with friends was associated with more time using electronic games on weekend days in both sexes (Boys, 3.31 (3.12, 3.51); Girls, 3.13 (2.67, 3.67)).
Reductions in screen behaviours may be targeted throughout the day but should be sensitive to differing context. Family members, friends, and adolescent themselves may be important target groups in behaviour change interventions. Future research to address the complex interplay between social context, content and quality of screen behaviours will aid the design of behaviour change interventions.
