Abstract
Adolescent suicide is a serious global health concern. Although familial transmission of suicidal behaviors has been identified in previous research, the effects of parental gender remain unknown. This study identified the influence of parental suicidal behaviors on suicide attempts among adolescent girls. We collected data through a cross-sectional, nationwide, population-based survey in South Korea and evaluated data from 890 adolescent girls (aged 12–18 years) who had attempted suicide and their parents. Hierarchical logistic regression was used to analyze the risk factors related to suicide attempts among adolescent girls. The final model indicated that mothers’ suicidal plans and attempts (OR = 6.39, OR = 12.38, respectively) were important risk factors for suicide attempts in adolescent girls. Future studies should identify specific methods for effective prevention and treatment through path analysis of the related factors affecting suicidal behavior of adolescents according to their parents’ gender.
Highlights
Considering the increasing suicide rates among adolescent girls in South Korea and the effect of parents’ suicidal behavior on their offspring, we investigated the risk factors related to suicidal attempts, and the influence of parental suicidal behaviors on suicidal attempts of adolescent girls
Our results reveal that the average sleep duration of adolescent girls who attempted suicide was 6.62 h, which is insufficient, based on the National Sleep Foundation (NSF)
We found that suicidal plans and attempts in adolescent girls’ mothers were important risk factors for suicide attempts among adolescent girls
Summary
This study was conducted using data gathered from the Korean National Health and Nutrition Examination Survey (KNHANES) by the Division of Chronic Disease Surveillance of the Korean Centers for Disease Control and Prevention. We analyzed data from 2015 to 2018 [25,26] using a cross-sectional design. Since the KNHANES launched a questionnaire on suicidal behaviors of adults and adolescents in 2015, this study analyzed data from 2015 to 2018 to confirm the relationship between suicidal behaviors of adolescent girls and their parents. The participants comprised 890 adolescent girls aged 12–18 years and their 1500 parents (645 fathers, 855 mothers); they were representative of a nationwide non-institutionalized population in South Korea [26]. The Institutional Review Board/Ethics Committee of Soonchunhyang University, Seoul Hospital of Korea approved the study protocol (IRB No 2021-01-002)
