Background: Globally, suicidal behaviour amongst adolescents is a growing public health issue, which may result in early death and lifelong stigma. This study aimed to estimate the lifetime and 12-month prevalence of suicidal behaviours and identify patterns and predictors among in-school adolescents in Yenagoa, Bayelsa state.

Method: A total of 336 adolescents aged 10-19 years who were attending school were randomly selected for a cross-sectional study. Data was collected through a self-administered questionnaire that had been adapted from the 'suicide section' of the Nigerian version of the Global School-based Health Survey questionnaire. SPSS version 25 was used for analysis, which included univariate, bivariate and multivariate analysis.

Result: Lifetime prevalence of suicidal ideation, plan, and attempt were 33.6%, 18.8%, and 11.6% respectively. The 12-month prevalence for suicide plans and attempts was 12.2% and 7.7% of participants respectively. Risk factors identified for suicide behaviour were being female, attending a school exclusively for girls, coming from a polygamous household, feeling alone, hopeless, and sense of being a burden, having been bullied and assaulted in the past; growing up in a troubled environment; having a family history of suicide attempts and having access to means of suicide. Drug abuse (p = 0.027) were associated with increased likelihood of suicidal attempt only.

Conclusion: Suicidal behaviour is common among adolescents due to various factors. Early identification is crucial to prevent recurrent tendencies. Collaboration between schools, parents, public health institutions, relevant stakeholders, and Non-Governmental Organisations is necessary to develop comprehensive approaches for timely intervention.
