Background:Non‐suicidal self‐injury(NSSI),suicidal ideation(SI),and suicide attempts(SA)are major concerns among college students.Sleep may be a modifiable factor,but its associations with NSSI,SI,and SA remain unclear.Methods:A cross‐sectional survey of 10,498 college students using a selfreport questionnaire.Sleep health indicators include insomnia symptoms,duration,chronotype,snoring,and daytime sleepiness.Multivariable logistic regression models and restricted cubic spline analyses were used to examine associations between sleep patterns and self‐injurious behaviors.Results:The prevalence of NSSI,SI,and SA was 4.8%,29.7%,and 3.7%,respectively.Participants with higher healthy sleep scores exhibited significantly reduced risks of NSSI,SI,and SA,with dose‐response relationships observed.Each one‐point increase in the sleep score was associated with a 43%lower risk of NSSI(odds ratios(OR)=0.57,95%CI:0.52–0.62),a 37%lower risk of SI(OR=0.63,95%CI:0.61–0.66),and a 48%lower risk of SA(OR=0.52,95%CI:0.48–0.58).Conclusion:Healthy sleep patterns were significantly associated with reduced risks of NSSI,SI,and SA among Chinese college students.These findings underscore the importance of promoting comprehensive sleep health as a public health strategy to mitigate self‐injurious behaviors in young populations.
