Associations Between Sleep Duration and Suicidality in Adolescents: A Systematic Review and Dose–Response Meta-Analysis

Sleep duration has received considerable attention as a potential risk factor of suicidality in youths; however, evidence on the dose–response association between sleep duration and suicidality has not been synthesized. This meta-analysis examined linear and nonlinear dose–response relationships between sleep duration and the risk of suicidality in adolescents and explored potential moderators of the associations. Electronic databases, namely EMBASE, PubMed, PsycINFO, Wanfang Data (Chinese database), and the China Knowledge Resource Integrated Database, were searched from their inception to April 18, 2017.
