Suicide is one of the leading causes of death among children and adolescents. Most studies about the burden and risk factors for suicide have been conducted in high-income countries. However, there ...is a dearth in the literature about the burden and risk factors for suicide among children and adolescents in low- and middle-income countries including within Sub-Saharan Africa (SSA). There is need to summarise the available literature about the burden and risk factors for suicide among children and adolescents in SSA. In this review, we will (a) determine the overall prevalence of suicidal ideation, suicidal attempt and completed suicide among children and adolescents in SSA; (b) describe the methods (such as hanging, firearms, overdose, poisoning, drowning and burning) used for suicidal attempt, and completed suicide among children and adolescents in SSA; and (c) document the risk factors for suicidal ideation, suicidal attempt and completed suicide among children and adolescents in SSA.
The review will be conducted and reported in accordance to the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement. We will include journal articles that have documented the prevalence and risk factors for suicidal ideation, suicidal attempt and completed suicide among children and adolescents aged 5-19 years in SSA. We will also include accessible grey literature about the topic. Qualitative studies will be excluded from the study since they are limited in estimating prevalence. We will search different search engines including PUBMED, EMBASE, Psych-INFO, Cochrane Library, Africa wide-information and global health using suicide, adolescents and children, SSA as the keywords. We will use a meta-analysis, should we find that there is no heterogeneity between included studies.
This protocol describes a systematic review of observational studies reporting completed suicide, suicidal ideation and suicidal attempt among children and adolescents in sub-Saharan Africa. We anticipate that once this review is complete and published, our findings will be of interest to adolescents with suicidal behaviour, their families and caregivers, clinicians and other healthcare professionals, scientists and policy makers.

Abstract Background Family studies, including twin and adoption designs, have shown familial transmission of suicidal behaviors. Early environmental risk factors have an important role in the ...etiology of suicidal behavior. The aim of the present study was to assess the impact of family history of suicide and childhood trauma on suicide risk and on severity of suicide attempt in suicide attempters. Methods A total of 181 suicide attempters were included. Family history of suicide was assessed with the Karolinska Suicide History Interview or through patient records. Childhood trauma was assessed with the Karolinska Interpersonal Violence Scale (KIVS) measuring exposure to violence and expressed violent behavior in childhood (between 6 and 14 years of age) and during adult life (15 years or older). Suicide intent was measured with the Freeman scale. Results Male suicide attempters with a positive family history of suicide made more serious and well planned suicide attempts and had a significantly higher suicide risk. In logistic regression, family history of suicide and exposure to interpersonal violence as a child were independent predictors of suicide in male suicide attempters. Limitations The information about family history of suicide and exposure to interpersonal violence as a child derives from the patients only. In the first part of the inclusion period the information was collected from patient records. Conclusions The results of this study imply that suicides among those at biological risk might be prevented with the early recognition of environmental risks.
Abstract Based on a sample of 9085 16- to 19-year-old students attending all high schools in Iceland in 2004, the current study examines depressed mood and anger as potential mediators between family ...conflict/violence and sexual abuse, on the one hand, and suicidal ideations and suicide attempts on the other. Agnew's general strain theory provides the theoretical framework for the study. Structural equation modelling (SEM) was conducted allowing explicit modelling of both direct and mediating effects using observed and latent variables. The findings showed that both depressed mood and anger mediated the relationship between family conflict/violence and sexual abuse and suicidal attempts. However, when testing the mediating pathways between sexual abuse and family conflict/violence and suicidal ideations, only depressed mood but not anger turned out to be a significant mediator. The authors discuss how these finding may inform and facilitate the design and development of interventions to reduce the likelihood of suicide attempts among young people.
Abstract Background The study aimed to examine the clinical correlates of polysubstance dependence. Subjects and methods Seven hundred and fifty two substance-dependent subjects were interviewed with ...the Mini-International Neuropsychiatric Interview, the Brown–Goodwin Assessment for Lifetime History of Aggression (BGLHA), and the Hamilton Depression Rating Scale (HDRS). Subjects completed the Childhood Trauma Questionnaire (CTQ), Eysenck Personality Questionnaire (EPQ), and Barratt Impulsivity Scale (BIS). Subjects found to have polysubstance dependence were compared with subjects with monosubstance dependence. Results Polysubstance dependence was found in 48.3% of the subjects. Subjects with polysubstance dependence were significantly younger, more were separated/divorced and unemployed, and they had significantly higher CTQ scores for childhood emotional and physical neglect, higher EPQ psychoticism scores, higher BGLHA aggression scores, and higher BIS impulsivity scores. Significantly more of the polysubstance dependent subjects had attempted suicide, self-mutilated, and exhibited aggressive behavior. Significantly more monosubstance dependent subjects had an Axis I psychiatric disorder and they had higher HDRS depression scores. Conclusions Polysubstance dependence is common among the groups studied and may be associated with certain socio-demographic, developmental, and personality factors.
Objective: We aimed to describe patterns of substance use among patients admitted to an emergency psychiatric unit for non-fatal suicidal behaviour (NFSB) or another psychiatric reason and establish ...whether there were significant differences in patterns of substance use between the two groups.
Methods: We employed a case-control design (N = 50) and collected data about participants' substance use in Cape Town, South Africa. Data were analysed using Chi-square and Mann-Whitney tests, factor analysis, and logistic regressions.
Results: Prevalence of lifetime Alcohol Use Disorder (AUD) was 60% in the NFSB group and 28% in the control group. 12% of the NFSB group and 20% of the control group had a lifetime Tobacco Use Disorder. Prevalence of lifetime illicit Substance Use Disorder was 44% in the NFSB group and 60% in the control group. Hospital admission for NFSB was associated with: any past 24-hour alcohol use; quantity of past 24-hour alcohol use; quantity of past-month alcohol use; lifetime AUD; past 12-month AUD; and current AUD; and was not associated with the use of any other substances (p<.05). Past 12-month AUD was the best predictor of hospital admission for NFSB, controlling for, respectively, any past 24-hour alcohol use (aOR = 13.33, p = .023) and quantity of past 24-hour alcohol use (aOR = 9.01, p = .022)
Conclusions: Patients admitted to emergency psychiatric units for NFSB have increased needs for the treatment of AUDs compared to patients admitted for another psychiatric emergency. Findings support calls for interventions to prevent NFSB among psychiatric patients with a history of AUD.
Key points
Rates of substance use among patients admitted to emergency psychiatric units in South Africa were high compared to the general population.
Hazardous alcohol use was uniquely associated with hospital admission for non-fatal suicidal behaviour compared to another psychiatric emergency.
Tobacco use and illicit substance use were not associated with hospital admission for non-fatal suicidal behaviour compared to another psychiatric emergency.
The association between hazardous alcohol use and hospital admission for non-fatal suicidal behaviour did not appear to be affected by demographic variables.
Patients admitted to hospital for non-fatal suicidal behaviour have increased needs for the treatment of alcohol use disorders compared to other psychiatric patients.
Registered nurses within public mental health services play crucial roles in helping people recover from suicidal crisis. However, there is a lack of understanding of how care is experienced in this ...context, and available evidence suggests that nurses and consumers are often dissatisfied with the quality of care. There is thus an imperative to generate understanding of needs and experiences of both groups with a view to informing practice development. This article summarizes qualitative findings from a multimethod study undertaken in Australia, which surveyed and interviewed mental health nurses who had recent experience of caring for consumers in suicidal crisis in a hospital setting, and interviewed consumers who had recovered from a recent suicidal crisis. A framework was developed to guide the study and support ethical imperatives; in particular, the promotion of consumer well‐being. The findings highlight that therapeutic interpersonal engagement between nurses and consumers was central to quality care. This was particularly noted, as engagement could help reduce consumer isolation, loss of control, distress, and objectification of the delivery of potentially‐objectifying common interventions. Of concern, the results indicate a lack of therapeutic engagement from the perspective of both consumers and nurses. Recommendations to promote fuller therapeutic engagement are presented.
Abstract Background Stressful life events (SLEs) play a key role in suicidal behavior among adults with alcohol use disorders (AUD), yet there are meager data on the severity of SLEs preceding ...suicidal behavior or the timing of such events. Method Patients in residential substance use treatment who made a recent suicide attempt (cases, n = 101) and non-suicidal controls matched for site ( n = 101) were recruited. SLEs that occurred within 30 days of the attempt and on the day of the attempt in cases were compared to SLEs that occurred in the corresponding periods in controls. SLEs were categorized by type (interpersonal, non-interpersonal) and severity (major, minor) and were dated to assess timing. Degree of planning of suicide attempts was also assessed. Results Major interpersonal SLEs conferred risk for a suicide attempt, odds ratio (95% CI) = 5.50 (1.73, 17.53), p = 0.005. Cases were also more likely to experience an SLE on the day of the attempt than on the corresponding day in controls, OR (95% CI) = 6.05 (1.31, 28.02), p = 0.021. However, cases that made an attempt on the day of a SLE did not make lower planned suicide attempts compared to other cases, suggesting that suicide attempts that are immediately preceded by SLEs cannot be assumed to be unplanned. Conclusions Results suggest the central importance of major interpersonal SLEs in risk among adults with AUD, a novel finding, and documents that SLEs may lead to suicide attempts within a short window of time (i.e., same day), a daunting challenge to prevention efforts.
Cardiovascular fitness influences many aspects of brain function. However, the relationship between cardiovascular fitness and suicidal behaviour is unknown. Therefore, we aimed to determine whether ...cardiovascular fitness at age 18 years is associated with future risk of suicide attempt/death.
We performed a population-based Swedish longitudinal cohort study of male conscripts with no previous or ongoing mental illness (n = 1,136,527). The conscription examination, which took place during 1968-2005, included the cycle ergonometric test and tests of cognitive performance. Future risk of suicide attempt/death over a 5- to 42-year follow-up period was calculated with Cox proportional hazards models controlling for several confounders including familial factors.
At least one suicide attempt was recorded for 12,563 men. Death by suicide without a prior attempt was recorded in 4814 additional individuals. In fully adjusted models low cardiovascular fitness was associated with increased risk for future attempt/death by suicide hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.64-1.94. The HR changed only marginally after exclusion of persons who received in-patient care for depression (HR 1.76, 95% CI 1.61-1.94). Poor performance on both the cardiovascular fitness and cognitive tests was associated with a fivefold increased risk of suicide attempt or suicide death (HR 5.46, 95% CI 4.78-6.24).
Lower cardiovascular fitness at age 18 years was, after adjustment for a number of potential confounders, associated with an increased risk of attempt/death by suicide in adulthood. It remains to be clarified whether interventions designed to improve fitness in teens can influence the risk of suicidal behaviour later in life.
The aim of this study was to examine the linkages between suicidal ideation and attempt in adolescence and subsequent suicidal behaviours and mental health in young adulthood.
Data were gathered ...during the course of a 25-year longitudinal study of a birth cohort of 1265 New Zealand children. The information collected included: (a) measures of suicidal thoughts and attempts in adolescence (< 18 years); (b) measures of suicidal ideation, suicide attempt, major depression, anxiety disorders, and substance use disorders in young adulthood (18-25 years); and (c) measures of childhood and family background, individual characteristics, and mental disorders in adolescence.
After statistical adjustment for confounding factors, suicide attempt in adolescence was associated with increased risks of subsequent suicidal ideation (OR 5.7) suicide attempt (OR 17.8) and major depression (OR 1.5). Those reporting suicidal ideation without suicide attempt showed moderate increases in risks of later suicidal ideation (OR 2.5), suicide attempt (OR 2.0) and major depression (OR 1.6). In addition, there was evidence of an interactive relationship in which suicidal behaviour in adolescence was associated with increased risks of later substance use disorders in females but not males.
Young people reporting suicidal ideation or making a suicide attempt are an at-risk population for subsequent suicidal behaviour and depression. Further research is needed into the reasons for suicidal adolescent females being at greater risk of later substance use disorder.
Abstract Background Suicide represents a substantial problem, with significant societal and personal impact. The identification of factors influencing suicide risk is an important step in preventing ...self-harming behaviour. In this article the authors explore whether emotional instability increases risk of suicide, beyond that of mood intensity. Method This article provides a summary of existing theory and indirect evidence in support of an association between emotional instability and suicidality. A systematic literature search (Embase, Medline, PsychInfo) was carried out on literature conducted up to October, 2011. Meta-analysis was used to assess the strength of the proposed association. Results The systematic search identified 20 journal articles meeting the inclusion criteria, including retrospective questionnaire design studies and research conducted across several time-points. Meta-analysis revealed a moderate association, which remained statistically significant even when only including studies conducted over multiple time-points. This effect was attenuated, but remained significant, when controlling for study selection bias. Limitations Retrospective questionnaire studies failed to adequately control for mood level. Little is still currently understood about the types of emotional instability (e.g., dysoria, anxiety) most associated with suicidality. Conclusions Future avenues of investigation include micro- to macro-longitudinal research and the differentiation of emotion subtypes and instability metrics. Momentary assessment techniques may help to detect subtle fluctuations in mood leading to more effective and immediate intervention. Psychosocial intervention strategies for treating unstable emotions are discussed.
