Age-Specific Association Between Sleep Health and Suicidal Thoughts: A Large Scale Cross Sectional Study
Summary
Poor multidimensional sleep health, especially insomnia and sleep variability, is linked to increased suicidal thoughts. This association is stronger in younger individuals, emphasizing the need for age-tailored sleep interventions.
Area of Science:
- Sleep Science
- Mental Health Research
- Public Health
Background:
- Sleep health is crucial for overall well-being.
- Previous studies focused on single sleep issues and suicidal ideation.
- A comprehensive understanding of multidimensional sleep health across the life course is lacking.
Purpose of the Study:
- To investigate the association between multidimensional sleep health and suicidal thoughts in a large Chinese adult sample.
- To examine the moderating effect of age on the relationship between sleep health and suicidal thoughts.
Main Methods:
- Utilized self-reported data from 35,502 Chinese adults.
- Assessed multiple dimensions of sleep health and suicidal thoughts.
- Employed linear regression, Canonical Correlation Analysis (CCA), and moderation tests.
Main Results:
- Poorer overall sleep health correlated with higher future suicide likelihood.
- Insomnia and sleep variability significantly drove the association between sleep patterns and suicidal behavior.
- Age moderated the sleep variability-suicidal thoughts link, with a stronger association in younger adults.
Conclusions:
- Multidimensional sleep health, particularly insomnia and sleep variability, is a significant correlate of suicidal thoughts.
- The relationship between sleep health and suicidal thoughts is age-specific.
- Developmentally tailored, sleep-focused interventions are necessary.
