Suicidal ideation among Tunisian adolescents and the association with adverse life experiences

Abstract

Abstract Background Youth suicidality is a significant public health problem. Understanding the factors leading to suicide is essential to implement effective preventive efforts. In this context, this study was conducted to assess the link between suicidal ideation and adverse life experiences among Tunisian school aged youth. Methods A cross-sectional survey was conducted among a sample of 2020 secondary school adolescents in 2016. An anonymous self-administered questionnaire was used to collect data. The adverse life events measured were: domestic violence, parental divorce, physical aggression, sexual abuse and a familial antecedent of suicide. Results Overall, 17.0% (95% CI [15.3%-18.6%]) reported having suicide ideation during the past 12 months with no gender difference (16.3% among girls and 17.3% among boys, p = 0.62). Among the participants, 26.7% experienced at least one adverse life experience. Those who reported domestic violence (Odds Ratio = 8.93; 95% CI = 6.84–11.66), parental divorce (Odds Ratio = 3.02; 95% CI = 1.57–5.79), physical aggression (Odds Ratio = 6.97; 95% CI =5.14–9.46), sexual abuse (Odds Ratio = 8.69; 95% CI =3.94–19.15), familial antecedent of suicide (Odds Ratio = 8.17; 95% CI = 5.75–11.60) were associated with increased odds of suicide ideation. Conclusions The prevalence of suicidal ideation observed in the survey area was relatively high and associated with all the measured life adverse events. These factors should be included in a suicide screening tool to be integrated in a suicide prevention program. Key messages Suicidal ideation among adolescents was associated with all the measured life adverse events. Identifying adolescents at higher risk of suicide and help them to cope with their adverse experiences could be effective to prevent taking action to attempt suicide.
