Sleep characteristics and non-suicidal self-injury: unveiling the association in depressed adolescents

Year: 2025

Type: article

Abstract: OBJECTIVE: To investigate subjective and objective sleep characteristics between adolescents with and without non-suicidal self-injury (NSSI) during depressive episodes. DESIGN: Case-control study. PARTICIPANTS: The study comprised 125 adolescents aged 12-19 years hospitalized between December 2022 and June 2024, stratified into NSSI (n = 70) and non-NSSI (n = 55) groups based on the presence or absence of non-suicidal self-injury behaviors. MEASUREMENTS: Subjective sleep characteristics were measured by Pittsburgh Sleep Quality Index (PSQI), and objective sleep characteristics were obtained through polysomnography. RESULTS: Significant between-group differences emerged in gender distribution, depression severity, anxiety levels, and psychological symptoms profiles (P < 0.05). Multiple logistic regression analyses revealed that NSSI was independently positively associated with subjective sleep insufficiency (OR = 3.71, 95%CI:1.38-9.98, P = 0.009) and objectively measured prolonged sleep latency (OR = 1.03, 95%CI:1.00-1.06, P = 0.024). CONCLUSIONS: NSSI was significantly associated with reduced sleep duration and elevated sleep latency, which may serve as potential non-invasive biomarkers for NSSI risk in adolescents during depressive episodes.
