Excessive screen time behaviors performed by children and parents at home is a major public health concern. Identifying whether child and parent screen time behaviors cluster and understanding correlates of these familial clusters can help inform interventions for the whole family. This study characterized familial typologies of screen time behaviors and identified key modifiable correlates of these typologies.
Parents participating in the cross-sectional Sitting in the Home (SIT) study reported the duration (mins/day) they and their child (aged 11.2 ± 2.62 years) spent in six screen time behaviors at home (computer/laptop for home/work, computer/laptop for leisure, TV/videos/DVDs, tablet/smart phone for home/work, tablet/smart phone for leisure, and electronic games) and completed items related to 21 potential correlates framed by an adapted Social Cognitive Theory, Family Perspective. Latent Class Analysis was used to identify typologies based on parent and child data for the six behaviors. Multinomial logistic regression analysis assessed the relative risk of typology membership for each potential correlate, adjusting for child and parent age and sex.
The sample comprised 542 parent-child dyads (parents: 40.7 ± 6.3 yrs., 94% female; children: 11.2 ± 2.6 yrs., 46% female). Three typologies were identified: 1) high computer/moderate TV (n = 197); 2) high TV/tablet/smartphone, low computer (n = 135); and 3) low-screen users (n = 210). 'Low-screen users' spent the least amount of time in all screen time behaviors (assigned as reference category). Greater child preference for screen time behaviors, parental support for screen time behaviors and frequency of homework requiring a tablet/laptop were associated with higher odds of being in the 'high computer/moderate TV' typology. The odds of being in the 'high TV/tablet/smartphone, low computer' typology were greater amongst children with a higher preference for screen time behaviors, and lower among more active parents.
Three familial typologies of screen time behaviors were identified. The findings highlight that screen time in the home can be influenced by the home environment, parental behaviours and role modelling, child preferences as well as school policies. Findings can inform the development of family screen time interventions, however more research exploring the influence of factors outside of the home is warranted.
儿童和家长在家过度使用屏幕的行为是一个主要的公共卫生问题。确定儿童和家长的屏幕时间行为是否聚集,并了解这些家庭群体的相关因素,可以为整个家庭的干预措施提供信息。本研究描述了家庭中屏幕时间行为的类型,并确定了这些类型的关键可改变的相关因素。
参与横断面家庭久坐研究(SIT)的家长报告了他们自己(年龄 40.7±6.3 岁,94%为女性)和他们的孩子(年龄 11.2±2.6 岁,46%为女性)在家中进行六种屏幕时间行为的时间(分钟/天):(用于家庭/工作的)电脑/笔记本电脑、(用于休闲的)电脑/笔记本电脑、电视/视频/DVD、(用于家庭/工作的)平板电脑/智能手机、(用于休闲的)平板电脑/智能手机和电子游戏),并完成了与适应社会认知理论和家庭视角的 21 个潜在相关因素有关的项目。潜在类别分析用于根据父母和孩子的数据识别六种行为的类型。使用多项逻辑回归分析评估每个潜在相关因素的类型成员资格的相对风险,同时调整孩子和父母的年龄和性别。
样本包括 542 对父母-孩子对(家长:40.7±6.3 岁,94%为女性;孩子:11.2±2.6 岁,46%为女性)。确定了三种类型:1)高电脑/中等电视(n=197);2)高电视/平板电脑/智能手机,低电脑(n=135);3)低屏幕使用者(n=210)。“低屏幕使用者”在所有屏幕时间行为中花费的时间最少(被指定为参考类别)。孩子对屏幕时间行为的偏好程度较高、父母对屏幕时间行为的支持程度较高以及需要平板电脑/笔记本电脑完成家庭作业的频率较高,与较高的“高电脑/中等电视”类型有关。“高电视/平板电脑/智能手机,低电脑”类型的可能性更大,儿童对屏幕时间行为的偏好程度较高,而活动较多的父母则较低。
确定了三种家庭屏幕时间行为类型。研究结果表明,家庭环境、父母行为和榜样作用、孩子的偏好以及学校政策都会影响家庭中的屏幕时间。研究结果可以为家庭屏幕时间干预措施的制定提供信息,但是需要更多的研究来探索家庭之外因素的影响。
