Objective:

To evaluate longitudinal associations between recreational screen time and sleep in early childhood, and attention-deficit/hyperactivity disorder (ADHD) at age 8 to 10 years.

Method:

Questionnaires from 2,768 mother-child pairs from the Dutch KOALA Birth Cohort Study were used. General estimating equation logistic regression analyses examined associations between screen time and sleep at age 2, 4, and 6, and ADHD at age 8 to 10. Linear regression analysis examined associations between television time, sleep and CBCL/2-3 scores at age 2.

Results:

Longitudinally, neither screen time nor sleep were associated with ADHD. Cross-sectionally, CBCL/2-3 externalizing symptom scores increased by 0.03 with every hour television time (95% CI 0.002–0.05) and increased by 0.02 per hour of less sleep (95% CI −0.03–−0.01).

Conclusion:

Despite an association with externalizing symptoms at age 2, screen time and sleep in early childhood were not associated with ADHD. Carefulness is warranted when extrapolating cross-sectional associations at early age to an ADHD diagnosis.

屏幕时间、睡眠与儿童注意力缺陷/多动障碍诊断之间的纵向关系。

客观的：

评估儿童早期娱乐屏幕时间和睡眠之间的纵向关联，以及 8 至 10 岁的注意力缺陷/多动障碍 (ADHD)。

方法：

使用了来自荷兰考拉出生队列研究的 2,768 对母子的问卷调查。一般估计方程逻辑回归分析检查了 2、4 和 6 岁时屏幕时间与睡眠之间的关联，以及 8 至 10 岁时 ADHD 之间的关联。线性回归分析检查了 2 岁时看电视时间、睡眠和 CBCL/2-3 分数之间的关联.

结果：

从纵向来看，屏幕时间和睡眠都与 ADHD 无关。横截面来看，CBCL/2-3 外化症状评分随着电视时间每小时增加 0.03（95% CI 0.002-0.05）而每小时睡眠时间减少增加 0.02（95% CI -0.03--0.01）。

结论：

尽管与 2 岁时的外化症状有关，但儿童早期的屏幕时间和睡眠与 ADHD 无关。在将早期的横断面关联外推到 ADHD 诊断时，需要小心谨慎。
