Single and Multiple Suicide Attempts: Prevalence and Correlates in School-Going Adolescents in Liberia in 2017

Background This investigation aimed to estimate the prevalence and correlates of single and multiple suicide attempts among adolescents in Liberia. Methods Cross-sectional nationally representative data were analysed from 2744 adolescents (18 years of median age) who participated in the “2017 Liberia Global School-Based Student Health Survey (GSHS)”. Results Results indicate that 33.7% of students had made a suicide attempt in the past 12 months (16.5% single and 17.2% multiple suicide attempts). In adjusted multinomial logistic regression analysis, having no close friends, loneliness, having been frequently physically attacked, ever used amphetamine and fast food intake were associated with multiple suicide attempts in the past 12 months. In addition, having been frequently in a physical fight and current tobacco use were associated with single suicide attempt. In sex stratified analyses, in addition, among boys frequent bullying victimization and among girls, parental tobacco use and parents never or rarely check on home work were associated with multiple suicide attempts. Multiple psychosocial distressors, multiple social-environmental factors, and multiple health risk behaviours were associated with single and multiple suicide attempts. Conclusion One in three students had made suicide attempt in the past 12 months (one in six students multiple suicide attempts) and several associated variables were detected which can aid in designing intervention strategies.


Background
Suicide is one of the major causes of death in young people. 1 Attempting suicide is an important factor that can lead to suicide death. 2 Programmes geared towards preventing suicide among adolescents need to be aware of the current trends of suicide attempts and its correlates. 3 In a multicountry school survey including adolescents, the pooled prevalence of past 12 months attempted suicide in 8 countries of the sub-Saharan African region was 19.3%, ranging from 10.2% in Tanzania to 27.9% in Benin. 4 In a national household survey among adults in Liberia in 2008, One in three respondents had participated in fighting forces and one in three of these were women, 44% had PTSD symptoms, 40% met the criteria for major depressive disorder, 11% reported suicidal ideation, 8% social dysfunction, and 6% attempted suicide. 5 "War exposure and post-conflict sexual violence, poverty, infectious disease, and parental death negatively impacted youth mental health in Liberia." 6 Key informants perceived that among adolescents/young adults in Liberia, suicidal ideation was ranked fourth highest emotional and behavioural problem, after alcohol, drug use and delinquent behaviour. 6 Conflict and post-conflict situations can be particularly stressful for children and adolescents facing the traumatising impact of direct exposure to violence as well as stressful living conditions. 7 There is a lack of systematic data about suicidal behaviour among adolescents in Liberia. 7 As previously reviewed in Pengpid and Peltzer, 8  In addition, recent large studies among adolescents showed that fast food consumption, soft drink intake, and sexual behaviour increased the likelihood of suicide attempts. 9-11 Studies on multiple suicide attempts found that lower social support, suicidal ideation, mental disorder, anxiety disorder, hopelessness, and family suicide history predicted multiple suicide attempts. [12][13][14] Moreover, several studies [15][16][17] showed a strong association between multiple adverse experiences and suicide attempts. It was hypothesised that sociodemographic factors, psychosocial distress, social-environmental factors, and health risk behaviours were associated with suicide attempts. The investigation aimed to estimate the prevalence and associated factors of single and multiple suicide attempts among school-going adolescents in Liberia.

Methods
Cross-sectional nationally representative data from the "2017 Liberia GSHS" were analyzed. 18 More details on the survey methodology and the data can be accessed; 18 "the overall response rate was 71%." 18

Measures
Outcome variable: Suicide attempt was assessed with the question, "During the past 12 months, how many times did you actually attempt suicide?" (number of times) Responses were grouped into 1=0 time, 2=1 time, and 3=2 or more times. 18 Covariates included demographic variables (age, sex, and school grade), six psychosocial distress variables, seven social-environmental indicators, and eight health risk behaviours. The selection of covariates was based on previous literature review. [8][9][10][11][12][13][14][15][16][17] Psychosocial distress variables included 1) having no close friends, 2) mostly or always felt lonely in the past 12 months, 3) mostly or always been worried about something that could not sleep in the past 12 months, 4) three or more days being bullied in the past 30 days, 5) two or more times physically attacked in the past 12 months, and 6) two or more times being in a physical fight in the past 12 months. 18 Social-environmental indicators 18 consisted of 1) mostly or always go hungry because of no food at home in the past 30 days, 2) never or rarely most school students were kind and helpful in the past 30 days, 3) parents or guardians never or rarely check on home work, 4) parents or guardians mostly or always go through your things without your approval, 5) parental tobacco use, 6) one or more days missing classes or school without permission in the past 30 days, and 7) emotional neglect was defined as rarely or never parental or guardian understanding of your problems and worries? OR rarely or never parents or guardians really know what you were doing with your free time when you were not at school or work? 19 Health risk behaviours included 1) current tobacco use, 2) one or more times got into trouble as a result of drinking alcohol, 3) current cannabis use, 4) ever used amphetamines, 5) intake of two or more softs drinks a day, 6) having fast food on two or more days in the past seven days, 7) ever had sexual intercourse with two or more people, and 8) had two or more times a serious physical injury in the past 12 months. 18

Data Analysis
Statistical analyses were done with "STATA software version 15.0 (Stata Corporation, College Station, Texas, USA)." Adjusted multinomial logistic regression was used to assess predictors of single and multiple suicide attempts (past 12 months), with no past 12-month suicide attempt as reference category. The missing values were not included in the analysis. P<0.05 was accepted as significant.

Results
The sample comprised 2744 school adolescents (18 years median age, 2 years interquartile range), 48.2% were female and 51.8% male. One in three of the participants (33.7%) had made a suicide attempt in the past year (16.5% single and 17.2% multiple suicide attempts). Further sample details are shown in Table 1.

Associations with Single and Multiple Suicide Attempts by Single Adverse Events
In adjusted multinomial logistic regression analysis, having no close friends, loneliness, having been frequently physically attacked, ever used amphetamine, and fast food intake were associated with multiple suicide attempts in the past 12 months. In addition, having been frequently in a physical fight and current tobacco use were associated with a single suicide attempt (see Table 2

Associations with Single and Multiple Suicide Attempts by Multiple Adverse Events
In the adjusted multinomial logistic regression analysis, compared to students who did not experience any psychosocial distress, students with 1, 2 and 3 or more psychosocial distress had an increased likelihood of single and multiple suicide attempts. Multiple social-environmental factors and multiple health risk behaviours were associated with single and multiple suicide attempts. The associations with multiple suicide attempts were stronger than with a single suicide attempt (see Table 3).

Discussion
The investigation aimed to estimate the prevalence and correlates of single and multiple suicide attempts in school adolescents in Liberia. The prevalence of past 12-month suicide attempts (33.7%) in this study was much higher than in 8 countries of the sub-Saharan Africa region (19.3%). 4 It is possible that the postconflict situation in Liberia contributes to the high rate of suicide attempts among adolescents. [5][6][7] Borba et al 6 note that the most significant mental health needs for children, adolescents, and young adults included both externalizing and internalizing (i.e., lack of motivation, sadness/depression, suicidal thoughts, hopelessness) symptoms and behaviours.

While these symptoms have been consistently documented in youth exposed to childhood adversity and exposure to traumatic experiences, these findings should be viewed in the context of the total breakdown of many protective communal, family, and societal structures. 6 Previous studies found a higher prevalence of suicide attempts (single and multiple) in girls than in boys, 20,21 while no significant sex differences were found in this study. This result seems to show that boys "internalize emotional-behavioural problems (leading more likely to suicidal ideation and suicide attempts)" 22 similarly than girls do. In a multicountry school survey among adolescents study, 20 suicide attempts increased with age, while age differences in the prevalence of single and multiple suicide attempts were not observed in this study. Unlike a previous study, 20 this investigation did not find an association between low economic status (mostly feeling hungry) and suicide attempt.
In agreement with previous studies, 20,21,23,24 this study found an association between loneliness, no close friends, bullying victimization, interpersonal violence and single and/or multiple suicide attempts. Several researchers 13,14 emphasised the importance of mental disorder and/or hopelessness in predicting multiple suicide attempts. These findings suggest the importance of treating psychosocial distress and prevention of bullying victimization and interpersonal violence to prevent suicide.
In agreement with previous investigations, 8,10,20,25 the findings of this research show an association between current tobacco use, drug use, parental tobacco use and  fast food intake with single and/or multiple suicide attempts. Several mechanisms have been proposed 10 for the link between fast food consumption and suicide attempts, for example, fast food consumption may increase risk for suicide attempts by increasing vulnerability to traumatic stress via alterations in brain structure and function, with stress being a well-known predictor of suicide attempts in adolescents. 10,26 Some research 9,11,27 showed an association between sexual behaviour, injury, soft drink intake and suicide attempt, while this study did not discover such links.
Only among girls, this study found an association between social-environmental factors (parental tobacco use and parents never/rarely check home work) and multiple suicide attempts, which concurs with some previous research. 20,25 In agreement with former research, [15][16][17] this study showed a strong association between multiple adverse experiences and single and multiple suicide attempts, and appeared to be stronger in multiple suicide attempts. This seems to confirm a dose-response relationship between the more adverse experiences, the more likely multiple suicide attempts are made.
Study limitations include that this investigation was limited because of its cross-sectional design, and the inclusion of only school adolescents. The questionnaire administered was by self-report, including suicidal behaviour, psychosocial distress, and health risk behaviours, and could have led to bias in reporting. Given that the information has not been validated, future research should validate these data. An additional limitation was that the GSHS in Liberia did not assess help-seeking behaviours for suicidal behaviours.
The manuscript is based on a self-report, and given information has not been validated. Thus, the authors should highlight this limitation and warn clearly about this possible bias. In addition, future research should validate these data.

Conclusion
The study found among school-going nationally representative adolescents in Liberia that one in three students had made a suicide attempt in the past 12 months (one in six students multiple suicide attempts). Several risk factors, including having no close friends, loneliness, having been frequently physically attacked, ever used amphetamine, fast food intake, having been frequently in a physical fight, current tobacco use, frequent bullying victimization, parental tobacco use and parents never or rarely check on home work were identified for both or one of the sexes for multiple and/or single suicide attempt, which can assist in guiding interventions to prevent suicidal behaviour in this adolescent school population.
