This study found that frequent nightmares and restless legs syndrome symptoms were independently associated with subsequent suicidal ideation or attempts among college students.
Background: Sleep disturbance can be an important predictor associated with suicide behaviors. However, to date, few studies have examined the prospective relationships between different types of sleep disturbance and suicidal behaviors. The current study examined which sleep disturbance types were independent risk factors for subsequent suicidal behaviors in a large sample of Chinese college students. Methods: Data came from a large-scale health-related cohort study in Guangdong, China. Participants were 11,740 college students initially assessed in March and April in 2019 and reassessed six month later. Selfadministered structured questionnaires were used to assess suicidal behaviors, insomnia, nightmares, sleep disordered breathing (SDB) symptoms, restless legs syndrome (RLS) symptoms, depression, substance abuse and demographic characteristics. A series of logistic regression analyses were conducted to examine the associations between different types of sleep disturbance and suicidal behaviors. Results: Overall, 12.2% and 1.2% of college students reported suicidal ideation and attempts at baseline, and 8.6% and 2.4% reported similar behavior at follow-up. After adjustment for key covariates and prior suicidal behaviors, frequent nightmares (AORs = 1.35-1.69) and RLS symptoms (AOR = 1.37) at baseline predicted subsequent suicidal ideation, and only frequent nightmares (AOR = 2.40) at baseline predicted subsequent suicidal attempts. Limitations: All measures were based on self-report instead of objective assessments or clinical diagnostic evaluations. Conclusions: Frequent nightmares and RLS symptoms were independently associated subsequent suicidal ideation or attempts. Screening and managing sleep disturbance may be helpful for reducing the risk of suicidal behaviors among college students.
