“…The registration of outcome data has been described in more detail previously [ 10 ]. We registered all self-harm episodes that required hospitalisation from 1 January 1995 to 31 December 2010, based on a list of all acute admissions for persons eligible for Young-HUNT 1, at the two hospitals serving the catchment area for the study.…”

“…Also, there is evidence to suggest an association between self-harm risk and drug/alcohol misuse, stressful life events, and socioeconomic disadvantages [ 5 , 8 ]. Sleep problems have been associated with self-harm in two Norwegian studies [ 10 , 11 ]. Motivations for self-harm, and associated predictors are overlapping in different sub-populations and the general population, albeit with some differences.…”

BackgroundSelf-harm is associated with increased suicide risk, and constitutes a major challenge in adolescent mental healthcare. In the current study, we examined the association between different aspects of adolescent health and risk of later self-harm requiring hospital admission.MethodsWe linked baseline information from 13 to 19 year old participants (n = 8965) in the Norwegian Young-HUNT 1 study to patient records of self-harm hospitalisation during 15 years of follow-up. We used Cox regression to estimate risk factor hazard ratios (HR).ResultsEighty-nine persons (71% female) were admitted to hospital because of self-harm. Intoxication/self-poisoning was the most frequent method (81%). Both mental (anxiety/depression, loneliness, being bullied) and somatic (epilepsy, migraine) health issues were associated with up to fourfold increased risk of self-harm-related hospital admission.ConclusionsSeveral health issues during adolescence markedly increased the risk of later self-harm hospitalisation. Current findings should be incorporated in the strive to reduce self-harming and attempted suicides among young people.

“…A handful of longitudinal studies partially supported these findings, where sleep difficulties, and particularly insomnia, predicted later engagement in NSSI (Bandel & Brausch, 2020; Junker, Bjørngaard, Gunnell, & Bjerkeset, 2014; Lundh et al., 2013; Wong et al., 2011). However, this link disappeared when controlling for previous psychopathology (Bandel & Brausch, 2018; Junker et al, 2013). Although informative, these studies have limitations.…”

We propose a theoretical model of insomnia symptoms and non‐suicidal self‐injury (NSSI) that posits bidirectional linkages. We hypothesised that heightened depressive symptoms and impulsivity that result from insomnia increase NSSI. We also posit that the shame associated with NSSI triggers repetitive negative thinking, in turn increasing insomnia. Using three longitudinal waves of questionnaire data collected annually from a sample of Swedish adolescents (n = 1,457; Mage = 13.2, SD = 0.43; 52.7% boys), we assessed the mediating role of depressive symptoms, impulsivity, rumination, and worry on the link between insomnia and NSSI. After controlling for depressive symptoms, we found that insomnia was related to increases in NSSI from the second to the third time point (ß23 = 0.09, p = .01). NSSI was consistently related to increased insomnia (ß12 = 0.09, p = .01; ß23 = 0.11, p < .001). In addition, depressive symptoms (ßind = 0.01, p = .02), but not impulsivity (ßind = 0.01, p = .09), mediated the path from insomnia to increased NSSI. Neither worry (ßind = 0.00, p = .59) nor rumination (ßind = 0.00, p = .96) mediated the link between NSSI and increased insomnia. We conclude that NSSI and insomnia maintain each other over time. Thus, screening adolescents for insomnia symptoms may help identify those at risk of NSSI. Although depression seems to explain why insomnia is a risk factor for NSSI, further studies should investigate why NSSI plays a role in the maintenance of insomnia. This understanding will lay the foundation for intervention.

“…Until now, however, few researches have studied the association between sleep duration and NSSI. Previous studies have shown that the close link between sleep problems and self-harm; Di culties initiating sleep, early morning wakening, short sleep duration, severe sleep complaints, daytime sleepiness, and nightmares were associated with increased risk of self-harm in a dose-dependent manner [28,29,54,55]. In this study, we found that, after controlling for potential confounding factors, compared to the weekend catch-up sleeping for 0-1 hours, males who slept < 0 hours or ≥ 3 hours had higher risk of NSSI.…”

Background Previous researches showed a positive association between short sleep duration and non-suicidal self-injury (NSSI) among adolescents, but few studies have described the effects of oversleeping and weekend catch-up sleep duration on NSSI. The present study aims to explore the nonlinear relationship between sleep duration and NSSI among Chinese adolescents. Methods China’s National Adolescent Health Surveillance data from 2014 to 2015 were collected from 15,713 students in four provinces within China. A self-report questionnaire was used to assess sleep duration and 12-month NSSI. Binomial logistic regression models were used to examine the associations of NSSI with sleep duration. The locally estimated scatter plot smoothing (LOESS) method was used to help explore the associations of total NSSI number with sleep duration, and binomial regression analysis was used to help test this relationship. Results About 68.5% of adolescents reported sleeping less than 8 h on weeknights while 37.8% slept more than 10 h per night during weekends. The 12-month prevalence rate of NSSI was 29.4%. Compared to the weekend catch-up sleeping for 0–1 hours, those who slept < 0 hours (adjusted Odd Ratio (aOR) = 1.38, 95% Confidence Interval (95% CI): 1.16–1.64) had higher risk of NSSI. Males who reported ≥ 3 hours of weekend catch-up sleep were significantly increased odds of NSSI (aOR = 1.20, 95%CI: 1.01–1.42). Notably, the positive U-shape association was observed between the entire sleep duration and total NSSI number. Conclusions The findings reveals that the nonlinear relationship between sleep duration and non-suicidal self-injurious behaviour among Chinese adolescents. Therefore, it is necessary to be vigilant and screen for sleep duration among adolescents in NSSI treatment or prevention.
