Title: Adverse childhood experiences and hearing loss: the mediating role of sleep disorders in a Chinese cohort
Source: BMC Psychiatry, Volume 25, Article 1098 (2025)
Introduction
- Background: Adverse childhood experiences (ACE) are strongly linked to chronic diseases, but their connection to hearing loss (HL) and underlying mediators like sleep disorders is not well understood.
- Objective: To investigate whether sleep disorders mediate the relationship between ACE and HL in middle-aged and older Chinese adults.
Methods
- Participants: 7,534 individuals aged ≥45 years from the China Health and Retirement Longitudinal Study (CHARLS).
- Measures:
- ACE assessed retrospectively by 12 items, score ranges 0–12, analyzed continuously and by quartiles.
- Hearing loss (HL) defined by self-reported fair/poor hearing or hearing-aid use.
- Sleep disorders indicated by restless sleep occurring ≥1 day per week.
- Analysis: Logistic regression and causal mediation models were adjusted for socio-demographic, behavioral, and clinical factors.
Results
- Mean ACE score was 3.6 ± 1.8.
- 47.2% reported sleep disorders.
- Participants with ≥5 ACEs had a 1.63-fold higher odds of HL compared to those with 0 ACEs (95% CI: 1.22–2.18; p = ???) — Unfortunately, the significance value and further results are cut off.
