ACEs are associated with shorter sleep duration and poorer sleep quality in middle-aged and older adults, with each additional ACE increasing the risk of incident inadequate sleep and sleep disturbance, and the associations varied across ACEs exposure patterns.
Key Findings
Results
Each additional adverse childhood experience was associated with a higher risk of incident inadequate sleep over a 9-year follow-up.
Hazard ratio for incident inadequate sleep per additional ACE: HR = 1.08 (95% CI: 1.06–1.10)
Study followed 12,363 participants aged ≥45 years across five waves from 2011 to 2020
Cox regression models were used to estimate this association
ACEs occurring before age 18 were retrospectively assessed
Results
Each additional adverse childhood experience was associated with a higher risk of incident sleep disturbance over a 9-year follow-up.
Hazard ratio for incident sleep disturbance per additional ACE: HR = 1.10 (95% CI: 1.08–1.12)
Cox regression models were used with multivariable adjustment
Follow-up period spanned 9 years across five waves of CHARLS data
Sleep disturbance was measured repeatedly across all five waves
Results
ACEs were associated with poorer sleep quality in middle-aged and older adults.
Odds ratio for poorer sleep quality per additional ACE: OR = 1.18 (95% CI: 1.16–1.20)
Ordinal logistic regression was used to estimate this association
Sleep quality was measured across five waves over the 9-year follow-up
Mean participant age at baseline was 58.0 ± 8.96 years; 47.43% male
Results
ACEs were associated with shorter sleep duration in middle-aged and older adults.
Linear mixed-effects regression coefficient: β = -0.11 (95% CI: -0.13 to -0.09)
This represents shorter sleep duration per additional ACE exposure
Sleep duration was measured repeatedly across five survey waves
Linear mixed-effects models accounted for the repeated-measures study design
Results
Exposure to 4 or more ACEs was associated with substantially higher odds of belonging to the 'Severely Restless Short Sleep' trajectory.
OR = 2.23 (95% CI: 1.69–2.96) for ≥4 ACEs versus the reference group
One of the five trajectories was labeled 'Severely Restless Short Sleep'
Latent Class Analysis (LCA) was used to identify clustering patterns of ACEs exposure
Results
Restricted cubic spline regression supported a linear dose-response relationship between ACEs and adverse sleep outcomes.
No nonlinear threshold effect was detected; risk increased linearly with each additional ACE
RCS regression was used to assess potential nonlinear associations across the ACE count distribution
This linear relationship applied across multiple adverse sleep outcomes examined in the study
Results
Certain ACE clusters showed stronger associations with adverse sleep outcomes than others.
Latent Class Analysis identified distinct clustering patterns of ACEs among participants
The associations between ACEs and sleep outcomes varied across different ACE exposure patterns
The paper notes that 'certain ACEs clusters showed stronger links with adverse sleep'
This finding suggests the type and co-occurrence of ACEs, not just count, may matter for sleep health
Methods
The study sample comprised 12,363 Chinese middle-aged and older adults drawn from five waves of the China Health and Retirement Longitudinal Study (CHARLS).
Participants were aged ≥45 years at baseline; mean age 58.0 ± 8.96 years
47.43% of participants were male
Data spanned 2011–2020 across five survey waves
ACEs were retrospectively assessed as those occurring before age 18
What This Means
This research suggests that difficult or traumatic experiences during childhood — such as abuse, neglect, or household dysfunction — are linked to worse sleep health decades later in middle age and older adulthood. Using data from over 12,000 Chinese adults followed for nine years, the study found that each additional adverse childhood experience (ACE) meaningfully increased the chances of developing problems like insufficient sleep duration and sleep disturbances. People who experienced four or more ACEs were more than twice as likely to fall into a 'severely restless short sleep' pattern compared to those with fewer ACEs, and this relationship followed a straight-line dose-response pattern — meaning more ACEs consistently meant worse sleep, with no apparent cutoff below which ACEs had no effect.
The study also found that not all ACEs are equal in their impact on sleep. Certain combinations or clusters of childhood adversities were more strongly linked to poor sleep than others, suggesting the nature and co-occurrence of early-life stressors matter, not just how many occurred. These associations held up across multiple ways of measuring sleep — including sleep quality scores, sleep duration, and trajectory patterns tracked over nearly a decade — and were observed even after accounting for other factors that could influence sleep.
This research suggests that a person's childhood history may be a relevant factor when healthcare providers are evaluating or treating sleep problems in middle-aged and older adults. Early prevention of adverse childhood experiences could have long-term protective effects on sleep health, and screening for ACE history might help identify adults who are at higher risk for chronic sleep difficulties.
