Associations between adverse childhood experiences and insomnia: The moderating role of social capital in a three-year longitudinal study from the Japan Gerontological Evaluation Study
View abstract on PubMed
Summary
This summary is machine-generated.Adverse childhood experiences (ACEs) increase insomnia risk in older adults. Social capital, particularly social cohesion, offers some protection, but its role in modifying the ACE-insomnia link is limited.
Area Of Science
- Gerontology
- Sleep Medicine
- Public Health
Background
- Adverse childhood experiences (ACEs) are linked to long-term sleep disturbances.
- Social capital may improve sleep in older adults, but its moderating effect on ACEs and insomnia is not well understood.
Purpose Of The Study
- To investigate whether social capital modifies the association between ACEs and insomnia in older adults.
Main Methods
- Longitudinal study of 8890 Japanese adults aged 65+ (2013-2016).
- Assessed insomnia using the Athens Insomnia Scale.
- Measured ACEs retrospectively and social capital (civic participation, social cohesion, reciprocity) prospectively.
Main Results
- Each additional ACE increased insomnia probability (RR=1.19).
- Higher social capital components were inversely associated with insomnia (RRs=0.87-0.94).
- Limited effect modification observed; civic participation slightly amplified the ACE-insomnia association, while social cohesion did not.
Conclusions
- Social capital demonstrated limited modification of the ACE-insomnia association in older adults.
- Social cohesion showed independent protective effects on sleep.
- Community-building initiatives may support sleep health, especially for individuals with a history of ACEs.
