Prevalence and risk factors of sleep disturbances among adolescents with non-suicidal self-injury: a systematic review and meta-analysis.
Synthesis in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo estimate the pooled prevalence of sleep disturbances and identify associated risk factor among adolescent with non-suicidal self-injury (NSSI).
methodsA systematic search of PubMed, Web of Science, Embase, PsycINFO, CNKI, and SinoMed was conducted up to March 2026. Eligible studies included adolescents aged 11–19 years with NSSI that reported the prevalence or risk factors of sleep disturbances. Cross-sectional and longitudinal studies were included. Two reviewers independently conducted study selection, data extraction, and quality assessment. Pooled estimates were calculated using random-effects models.
resultsA total of 23 studies were included in the review. The pooled prevalence of sleep disturbances across 13 studies was 41% (95%CI: 39%–44%; I²= 76.8%). Overall, 11 risk factors were identified across 15 studies, of which four factors were eligible for meta-analysis, including female sex, depression, emotional neglect, and externalizing problems. Significant associations were observed for depression (OR = 1.05, 95%CI: 1.03–1.07; I²= 69.1%) and female sex (OR = 1.74, 95%CI: 1.31–2.18; I²= 78.8%), whereas emotional neglect and externalizing problems were not significantly associated with sleep disturbances.
conclusionsSleep disturbances are highly prevalent among adolescents engaging in NSSI, particularly among females and those with depression. These findings underscore the need for routine sleep assessment within adolescent mental health screening. Nurses can play a key role in early identification, sleep-health education, and timely referral, supporting nurse-led models of early detection and prevention.
