abstract = {Approximately 4–11% of children suffer from sleep-disordered breathing (SDB), and children with obesity are at increased
risk. Both obesity and SDB have been separately associated with poorer brain health, yet whether SDB severity affects
brain health in children with obesity remains unanswered. This study aimed to examine associations of SDB severity with
academic performance and brain structure (i.e., total brain and gray and white matter volumes and gray matter volume in the
hippocampus) in children with overweight/obesity. One hundred nine children aged 8–12 years with overweight/obesity were
included. SDB severity and its subscales (i.e., snoring, daytime sleepiness, and inattention/hyperactivity) were evaluated via
the Pediatric Sleep Questionnaire (PSQ), and academic performance was evaluated with the Woodcock-Muñoz standardized
test and school grades. Brain structure was assessed by magnetic resonance imaging. SDB severity was not associated with
academic performance measured by the standardized test (all |β|> 0.160, P > 0.076), yet it was associated with the school
grade point average (β = -0.226, P = 0.007) and natural and social science grades (β = -0.269, P = 0.024). Intention/hyperactivity
seemed to drive these associations. No associations were found between SDB severity and the remaining school grades
(all β < -0.188, P > 0.065) or brain volumes (all P > 0.05).
Conclusion: Our study shows that SDB severity was associated with lower school grades, yet it was not associated with
the standardized measurement of academic performance or with brain volumes in children with overweight/obesity. SDB
severity may add to academic problems in children beyond the effects contributed by overweight/obesity status alone.},
