Prevalence and patterns of executive function, adaptive function, and behavioral outcomes in preschool and school age children with congenital diaphragmatic hernia.

BACKGROUND: Executive function, adaptive function, and behavioral outcomes in congenital diaphragmatic hernia (CDH) survivors have not been well studied.

AIM: To evaluate executive and neurobehavioral dysfunction in preschool and early school-aged children with CDH.

STUDY DESIGN: Retrospective cohort study.

SUBJECTS: All eligible CDH survivors ages 3 to 7 years enrolled in our follow-up program between February 2020 and February 2021.

OUTCOME MEASURES: The Behavior Rating Inventory of Executive Function (BRIEF), the Adaptive Behavior Assessment System, 2nd Edition (ABAS-II), and the Child Behavior Checklist (CBCL) were used to assess functional and behavioral outcomes. Summary scores were compared to standard population norms.

RESULTS: A total of 100 patients were enrolled during the study period. Of those, 73 parents completed at least one of the questionnaires, resulting in completion of the BRIEF, ABAS-II, and CBCL for 63, 68, and 63 patients, respectively. Preschool children had normal executive function (BRIEF-P) while global executive composite (P = 0.012) and the emotional regulation index (P = 0.010) for school age patients (BRIEF-2) were worse. CDH survivors had favorable adaptive functioning (ABAS-II). Mean CBCL scores for preschool attention problems (P = 0.018), school age attention problems (P = 0.001), and attention deficits hyperactivity problems (P = 0.027) were significantly worse. Prematurity, surrogate markers of disease severity, non-white race, and public insurance status were associated with worse neurobehavioral dysfunction in bivariable analysis.

CONCLUSIONS: The majority of preschool and school age CDH survivors have age-appropriate executive, adaptive and behavioral functioning. CDH survivors, however, have lower executive function and attention scores compared with the general population.
