Abstract

This study aimed to examine the association between sleep disturbance and attempted suicide in rural China. The study group included 409 suicide attempters from six rural counties in Shandong Province, China and an equal number of controls matched on age, sex, and residency. Sleep disturbance was assessed by the item "sleep restless" in the Center for Epidemiologic Studies Depression Scale. Sleep disturbance was reported more frequently in suicide attempters than in controls (1-2 days/week, 9.0% vs. 4.4%; 3-4 days/week, 11.5% vs. 2.4%; ≥5 days/week, 30.3% vs. 7.5%, χ = 128.72, p < 0.001). Suicide risk was significantly associated with increased frequency of sleep disturbance (OR = 3.98, 95% CI = 1.62-9.74 for 1-2 days/week; OR = 3.28, 95% CI = 1.21-8.84 for 3-4 days/week; OR = 2.41, 95% CI = 1.26-4.60 for ≥5 days/week) even after adjusting for potential psychosocial confounding factors and mental disorders. This finding may have important implications for early intervention and prevention of suicide.
