Examine prospective associations between parent-reported early childhood self-regulation problems and media exposure (television and video viewing) at 2 years. We hypothesized that children with poor self-regulation would consume more media, possibly as a parent coping strategy.
We used data from 7450 children in the Early Childhood Longitudinal Study-Birth Cohort. When children were 9 months and 2 years old, parents completed the Infant Toddler Symptom Checklist (ITSC), a validated scale of self-regulation. With daily media use at 2 years as our outcome, we conducted weighted multivariable regression analyses, controlling for child, maternal, and household characteristics.
Children watched an average of 2.3 hours per day (SD 1.9) of media at age 2 years. Infants with poor self-regulation (9-month ITSC score ≥3) viewed 0.23 hour per day (95% confidence interval [CI] 0.12-0.35) more media at 2 years compared with those with 9-month ITSC score of 0 to 2; this remained significant in adjusted models (0.15 hour per day [95% CI 0.02-0.28]). Children rated as having persistent self-regulation problems (ITSC ≥3 at both 9 months and 2 years) were even more likely to consume media at age 2 (adjusted β 0.21 hour per day [95% CI 0.03-0.39]; adjusted odds ratio for >2 hours per day 1.40 [95% CI 1.14-1.71]). These associations were slightly stronger in low socioeconomic status and English-speaking households.
Early childhood self-regulation problems are associated with mildly increased media exposure, even after controlling for important confounding variables. Understanding this relationship may provide insight into helping parents reduce their children's screen time.
研究父母报告的幼儿期自我调节问题与2岁时媒体接触（看电视和观看视频）之间的前瞻性关联。我们假设自我调节能力差的儿童会更多地接触媒体，这可能是一种父母的应对策略。
我们使用了来自幼儿纵向研究——出生队列中7450名儿童的数据。当儿童9个月和2岁时，父母完成了婴幼儿症状检查表（ITSC），这是一种经过验证的自我调节量表。以2岁时的每日媒体使用情况作为我们的结果，我们进行了加权多变量回归分析，并控制了儿童、母亲和家庭特征。
2岁儿童平均每天观看媒体2.3小时（标准差1.9）。自我调节能力差的婴儿（9个月时ITSC得分≥3）在2岁时每天观看媒体的时间比9个月时ITSC得分为0至2的婴儿多0.23小时（95%置信区间[CI]0.12 - 0.35）；在调整模型中这一差异仍然显著（每天0.15小时[95%CI 0.02 - 0.28]）。被评定为存在持续性自我调节问题（9个月和2岁时ITSC均≥3）的儿童在2岁时接触媒体的可能性更高（调整后的β值为每天0.21小时[95%CI 0.03 - 0.39]；每天观看超过2小时的调整后优势比为1.40[95%CI 1.14 - 1.71]）。在社会经济地位较低和说英语的家庭中，这些关联略强。
即使在控制了重要的混杂变量之后，幼儿期自我调节问题仍与媒体接触略有增加有关。了解这种关系可能有助于深入了解如何帮助父母减少孩子的屏幕时间。
