Prevalence and associated factors of suicide-related behaviors in Iranian students: a large sample cross-sectional study

Abstract Background Admission to the university changes life conditions and thereby increases mental pressure. If the students cannot bear the psychological pressure of being a student, that may lead to suicide among the vulnerable persons. Therefore, in this research, we would like to investigate the prevalence and associated factors of suicide-related behaviors in Iranian students. Methods This online, cross-sectional survey was performed from March 18 to April 15, 2023, in Iran. The questionnaires were completed by 2181 students. In this study, Perceived Stress Scale (PSS-4), Meaning in Life Questionnaire (MLQ), Generalized Anxiety Disorder Scale (GAD-7), and Suicidal Behaviors Questionnaire-Revised (SBQ-R), and Oslo Social Support Scale (OSSS-3) were used. Finally, we identified the factors associated with suicide-related behaviors using univariate and multiple regression. Results The prevalence of suicidal behaviors in students was 57.95%. According to the results, male gender, marriage, having meaning in life, occasional smoking, sleeping after 1 a.m., and having social support were associated with a reduced risk of suicide. In addition, a history of sexual abuse, more anxiety, and higher perceived stress were associated with an increased risk of suicide. Conclusions The prevalence of suicide-related behaviors in Iranian students was higher than expected. Urgent interventions should be considered to prevent students from committing suicide. Helping students find meaning in life, as well as eliminating the causes of students’ anxiety and stress, may be effective in this respect. Additionally, teaching students how to control anxiety and stress may be helpful.
