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.
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.
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).
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.
评估儿童早期娱乐性屏幕时间与睡眠的纵向关联，以及 8 至 10 岁时注意力缺陷/多动障碍（ADHD）的关联。
使用来自荷兰 KOALA 出生队列研究的 2768 对母子问卷调查。一般估计方程逻辑回归分析检查了 2 岁、4 岁和 6 岁时屏幕时间和睡眠与 8 至 10 岁时 ADHD 之间的关联。线性回归分析检查了 2 岁时电视时间、睡眠和 CBCL/2-3 评分之间的关联。
纵向来看，屏幕时间和睡眠均与 ADHD 无关。横向来看，CBCL/2-3 外化症状评分每增加一小时电视时间增加 0.03（95%CI 0.002-0.05），睡眠每减少一小时增加 0.02（95%CI -0.03--0.01）。
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推断为 ADHD 诊断时，应谨慎行事。
