Correlation between sleep disorder screening and executive dysfunction in children with attention deficit-hyperactivity disorder

Objective To compare frequency of sleep disorders (SD) and executive dysfunction (ED) in children with attention deficit-hyperactivity disorder (ADHD) and a control group. Method We studied 156 children with ADHD with a mean age of 8.5 years, and a control group with 111 children with a mean age of 8.3 years. We utilized the Pediatric Sleep Questionnaire (PSQ) to screen SD and the working memory measurement from the Wechsler intelligence scale for children (WISC-IV) to screen ED. Results We did not observe an increased frequency of SD in children with ADHD compared with the controls. However, we did identify ED in children with ADHD; additionally a significant correlation was observed between the type of ADHD and SD and among ED, WISC-IV measurements, and type of SD in children with ADHD. Conclusion An increase of SD frequency in children with ADHD was not observed, but we did identify ED in children with ADHD. Additionally, a correlation among ADHD types, SD, ED, and WISC-IV measurements was observed in children with ADHD.

研究目的：比较注意缺陷多动障碍（attention deficit-hyperactivity disorder, ADHD）儿童与对照组儿童的睡眠障碍（sleep disorders, SD）及执行功能障碍（executive dysfunction, ED）的发生频率。
研究方法：本研究纳入156名平均年龄为8.5岁的ADHD儿童，以及111名平均年龄为8.3岁的对照儿童。采用儿童睡眠问卷（Pediatric Sleep Questionnaire, PSQ）筛查睡眠障碍，使用韦克斯勒儿童智力量表第四版（WISC-IV）的工作记忆分量表筛查执行功能障碍。
研究结果：与对照组相比，本研究未观察到ADHD儿童的睡眠障碍发生频率升高。但本研究确认ADHD儿童存在执行功能障碍；此外，在ADHD儿童中，ADHD亚型与睡眠障碍之间、执行功能障碍与WISC-IV测评结果及睡眠障碍类型之间均存在显著相关性。
研究结论：本研究未观察到ADHD儿童的睡眠障碍发生频率升高，但确证ADHD儿童存在执行功能障碍。此外，ADHD儿童的ADHD亚型、睡眠障碍、执行功能障碍与WISC-IV测评结果之间存在相关性。
