Role of sleep problem on suicidal behaviour and non-suicidal self-injury among adolescents in Pokhara, Nepal.

INTRODUCTION

Sleep is a fundamental human requirement, considered one of the major contributing factors to physical and mental health, especially among adolescents. Poor quality sleep has many potential consequences including non-suicidal self-injury (NSSI), suicidal thoughts or behaviour and complete suicide. The NSSI and suicidal behaviour are increasing in Nepal. Thus, this study aimed to assess the role of sleep problem on suicidal behaviour and non-suicidal self-injury among adolescents in Pokhara metropolitan, Nepal.

METHODS

A cross-sectional analytical study was conducted among 673 adolescents using a multistage cluster sampling technique from private and public schools in Pokhara Metropolitan. Self-administered questionnaire was used for data collection. Collected data was entered and managed in EpiData (version 3.1) and analysed in IBM SPSS (version 23). Binary logistic regression was used to identify the association of sleep problem with NSSI and suicidal behaviour.

RESULTS

The study found that sleep problem (65.2%, 439), suicidal behaviour (18.6%, 125) and NSSI (57.9%, 390) were prevalent among adolescents in study setting. The presence of sleep problem significantly influenced the suicidal behavior (AOR = 3.88, 95% CI = 2.27-6.63) alongside the sex of student (AOR = 1.96, 95% CI = 1.28-3.00), adolescents from family having monthly income less than NPR 40,000 (AOR = 1.97 95% CI = 1.16-3.35) and private schools students (AOR = 2.99, 95% CI = 1.84-4.86). Likewise, sleep problem was also associated with non-suicidal self-injury (AOR = 3.24, 95% CI = 2.26-4.65), in addition to attending private school (AOR = 2.52, 95% CI = 1.71-3.72).

CONCLUSION

This study concludes that sleep problem is prevalent among the adolescents and increase the risk of NSSI and suicidal behaviour. Therefore, parents and teachers need to assess their conditions and help them maintain sound sleep. Additionally, suicide prevention strategies need to be adopted to mitigate further risk.
