It has been proposed that early-life screen use can impact the development of attention deficit hyperactivity disorder (ADHD) symptoms. Some studies have supported a weak association between higher levels of screen time and ADHD symptoms; however, this association is vulnerable to confounding and a causal explanation remains controversial.
To help address confounding in this association, we conducted inverse probability of treatment weighting (IPTW) analyses in a large UK-representative longitudinal sample to examine the impact of TV/video viewing at age 3 on ADHD symptoms at age 5.
Adjusting for confounding, we found that both no TV/video viewing and viewing more than 3 h of TV/video compared to between 1 and 3 h were associated with increased ADHD symptoms. However, the effect of no TV/video viewing was mirrored in a negative outcome control analysis, suggesting potential residual confounding.
Results are consistent with claims that high levels of TV/video viewing in preschool years may impact the development of ADHD symptoms. Trial-based research which examines the impact of reducing high levels of TV/video viewing in this age group would be merited to further illuminate this association and assess whether it is likely to reflect a causal effect.

有人提出，早年使用屏幕会影响注意力缺陷多动障碍（ADHD）症状的发展。一些研究支持较高的屏幕使用时间与ADHD症状之间存在微弱关联；然而，这种关联容易受到混杂因素的影响，因果关系的解释仍存在争议。
为了帮助解决这种关联中的混杂问题，我们在一个具有英国代表性的大型纵向样本中进行了治疗权重逆概率（IPTW）分析，以研究3岁时看电视/视频对5岁时ADHD症状的影响。
在对混杂因素进行调整后，我们发现，与1至3小时相比，不看电视/视频以及看电视/视频超过3小时都与ADHD症状增加有关。然而，在阴性结果对照分析中，不看电视/视频的影响也得到了体现，这表明可能存在潜在的残余混杂因素。
研究结果与以下观点一致，即学龄前大量看电视/视频可能会影响ADHD症状的发展。有必要开展基于试验的研究，以考察减少该年龄组大量看电视/视频的影响，从而进一步阐明这种关联，并评估其是否可能反映因果效应。
不适用。
