OBJECTIVES: Attention-deficit/hyperactivity disorder (ADHD) has been linked to sleep disturbances. There is little evidence of this association among a nationally representative sample of school-aged children. This study explored the association between current ADHD diagnosis and short sleep duration among U.S. school-aged children. Parent-reported severity of ADHD and short sleep duration among those with a current ADHD diagnosis was also assessed. METHODS: A secondary analysis of 2020-2021 National Survey of Children’s Health (NSCH) data including 26,148 U.S. children ages 6-11 years was performed. Sleep duration was categorized using the National Sleep Foundation’s age-specific recommendations defining <9 hours as short sleep duration. Weighted unadjusted and adjusted logistic regression models were performed. The adjusted models included child age, sex, race/ethnicity, health status, overweight status, screen time, physical activity, parent education, family structure, and federal poverty level. RESULTS: Nearly 10% of children currently had an ADHD diagnosis, with 62% having moderate or severe ADHD. Over one-third (35%) had reports of short sleep duration. Unadjusted (odds ratio [OR] = 1.58, 95% confidence interval [CI] = 1.35-1.84) and adjusted (adjusted OR [AOR] = 1.25, 95%CI = 1.06-1.47) results indicated that children with ADHD were at increased odds of having short sleep duration compared to children without ADHD. Among children with ADHD only, unadjusted (OR = 1.70, 95%CI = 1.26-2.31) and adjusted (AOR = 1.61, 95%CI = 1.19-2.19) results indicated that children with a moderate or severe diagnosis were at increased odds of having short sleep duration than children with a mild diagnosis. CONCLUSION: ADHD may influence short sleep duration among U.S. school-aged children. Behavioral sleep treatments should aim toward improving sleep duration among this population.

Thyroid hormones (THs) are endocrine factors that play an important role in brain development by modulating several neurodevelopmental processes, including neuronal migration, synaptogenesis, and myelination. Therefore, adequate regulation of these hormones is important for the structure and function of the brain. Recently, a close association between THs deficiency or dysfunction has been found with several neurodevelopmental disorders, including autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD). These results imply that thyroid hormones play an important role in the occurrence of neurodevelopmental disorders. In this review, we thoroughly investigate the biosynthetic pathways and regulatory mechanisms involved in thyroid hormones production. We also assess the importance of thyroid hormones during different periods of brain development, as well as the underlying molecular processes. Finally, we extend our discussion to explore the relationship between thyroid hormones and neurodevelopmental disorders. The objective is to provide mechanistic and clinical insights and to identify promising research avenues that could facilitate earlier diagnosis and intervention for these conditions.
