Adverse childhood experience (ACE) is a powerful risk factor for long-term sleep health. However, the degree to which ACE and its subtypes contribute to adulthood sleep problems remains unknown. For this systematic review and meta-analysis, PubMed, Embase, Web of Sciences, Cochrane library, and CNKI (Chinese) were searched from inception to 1 December 2021. Cohort studies that examined the association between ACEs (aged <18 y) and adulthood sleep outcomes (aged ≥18 y) were included. The most fully adjusted odds ratios (ORs) were extracted and pooled using the random-effects model. A total of nine articles involving 108 330 participants from five high-income countries were identified. Individuals with at least one ACE subtype were more likely to report adulthood sleep problems (OR = 1.14, 1.09-1.20, I2 = 77.5%, n = 9 studies) compared with those without ACE. The pooled ORs were approximately 1.20 for sexual, physical, and emotional abuse with high heterogeneity (I2 > 80%), 1.09 (95% CI: 0.99-1.19, I2 = 0%, n = 2) for neglect, and 1.21 (95% CI: 1.14-1.30, I2 = 73.6%, n = 3) for family dysfunction. Individuals with multiple ACEs were associated with a higher magnitude of the risk for sleep problems (OR = 1.33, 95% CI: 1.18-1.49, I2 = 87.3%, n = 3). In conclusion, the magnitude of the risk for sleep problems was similar across ACE subtypes except for childhood neglect. ACE may have cumulative detrime ntal effects on sleep health. More longitudinal evidence regarding ACE-sleep relationships, particularly in low- and middle-income countries, is needed. Furthermore, more policy efforts and evidence-based preventions are warranted to address ACEs among children.
