Objectives: This systematic review sought to examine existing studies addressing the relationship between Adverse Childhood Experiences (ACEs) and children’s sleep quality. Methods: An exhaustive literature search was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Records were identified through PubMed, CINAHL, Scopus, and Ovid.
Results: Fourteen studies were reviewed showing moderate evidence supporting the relationship between ACEs and sleep problems. Child sexual abuse was the most frequently reported form of maltreatment and was significantly linked to sleep problems. Common sleep problems included difficulty falling asleep, nocturnal awakening, nightmares, daytime sleepiness, and poor quality of sleep.
Discussion: Occupational therapy practitioners are encouraged to include evaluation and interventions for sleep disturbances in children who have known or suspected traumatic experiences. More specific studies are needed to further understand differences between ages and sexes and whether type of abuse makes a difference in this relationship.
