Lifetime Prevalence Of Suicidal Behaviors Research Articles

Global Lifetime and 12-Month Prevalence of Suicidal Behavior, Deliberate Self-Harm and Non-Suicidal Self-Injury in Children and Adolescents between 1989 and 2018: A Meta-Analysis.

Objective: This meta-analysis aimed to estimate the global lifetime and 12-month prevalence of suicidal behavior, deliberate self-harm and non-suicidal self-injury in children and adolescents. Methods: A systematic search for relevant articles published between 1989 to 2018 was performed in multiple electronic databases. The aggregate 12-month and lifetime prevalence of suicidal behavior, deliberate self-harm, and non-suicidal self-injury were calculated based on the random-effects model. Subgroup analyses were performed to compare the prevalence according to school attendance and geographical regions. Results: A total of 686,672 children and adolescents were included. The aggregate lifetime and 12-month prevalence of suicide attempts was 6% (95% CI: 4.7–7.7%) and 4.5% (95% CI: 3.4–5.9%) respectively. The aggregate lifetime and 12-month prevalence of suicidal plan was 9.9% (95% CI: 5.5–17%) and 7.5% (95% CI: 4.5–12.1%) respectively. The aggregate lifetime and 12-month prevalence of suicidal ideation was 18% (95% CI: 14.2–22.7%) and 14.2% (95% CI: 11.6–17.3%) respectively. The aggregate lifetime and 12-month prevalence of non-suicidal self-injury was 22.1% (95% CI: 16.9–28.4%) and 19.5% (95% CI: 13.3–27.6%) respectively. The aggregate lifetime and 12-month prevalence of deliberate self-harm was 13.7% (95% CI: 11.0–17.0%) and 14.2% (95% CI: 10.1–19.5%) respectively. Subgroup analyses showed that full-time school attendance, non-Western countries, low and middle-income countries, and geographical locations might contribute to the higher aggregate prevalence of suicidal behaviors, deliberate self-harm, and non-suicidal self-injury. Conclusions: This meta-analysis found that non-suicidal self-injury, suicidal ideation, and deliberate self-harm were the three most common suicidal and self-harm behaviors in children and adolescents.

Childhood Abuse and Suicidal Behaviors Among Chinese Migrant Workers: The Mediating Role of Alexithymia and Social Support

This study aims to investigate the lifetime prevalence of suicidal behaviors in a sample of Chinese migrant workers. It also examined the mediating role of alexithymia and social support in the link between childhood abuse and suicidal behaviors. A total of 1,563 migrant workers were surveyed by using cluster sampling. Results showed that the estimated lifetime prevalence of suicide ideation, plan, and attempt among Chinese migrant workers was 12.8%, 8.1%, and 4.6%, respectively. Structural equation modeling analyses revealed a significant positive association between childhood abuse and suicidal behaviors; this association was partially mediated by social support. A significant path from childhood abuse through alexithymia and social support to suicidal behaviors was also established. Findings of this study emphasize the importance of social support and alexithymia in understanding the possible mechanisms underlying the relationship between childhood abuse and suicidal behaviors and suggest possible avenues for suicide interventions.

Genetic risk of suicidal behavior in bipolar spectrum disorder: analysis of 737 pedigrees

Suicide is a significant cause of mortality in patients with major affective disorders (MAD), and suicidal behavior and MAD co-aggregate in families. However, the transmission of suicidal behavior is partially independent from that of MAD. We analyzed the lifetime prevalence of completed and attempted suicides in a large sample of families with bipolar disorder (BD), its relation to family history of MAD and BD, and the contribution of clinical and treatment factors to the risk of suicidal behavior. We studied 737 families of probands with MAD with 4919 first-degree relatives (818 affected, 3948 unaffected, and 153 subjects with no information available). Lifetime psychiatric diagnoses and suicidal behavior in first-degree relatives were assessed using semi-structured interviews, family history methods, and reviews of clinical records. Cox proportional hazard and logistic regression models were used to investigate the role of clinical covariates in the risk of suicidal behavior, and in the prevalence of MAD and BD. The estimated lifetime prevalence of suicidal behavior (attempted and completed suicides) in 737 probands was 38.4 ± 3.0%. Lithium treatment decreased suicide risk in probands (p = 0.007). In first-degree relatives, a family history of suicidal behavior contributed significantly to the joint risk of MAD and suicidal behavior (p = 0.0006). The liability to suicidal behavior is influenced by genetic factors (particularly family history of suicidal behavior and MAD). Even in the presence of high genetic risk for suicidal behavior, lithium treatment decreases suicide rates significantly.

Prevalence, Correlates, and Treatment of Lifetime Suicidal Behavior Among Adolescents

Although suicide is the third leading cause of death among US adolescents, little is known about the prevalence, correlates, or treatment of its immediate precursors, adolescent suicidal behaviors (ie, suicide ideation, plans, and attempts). To estimate the lifetime prevalence of suicidal behaviors among US adolescents and the associations of retrospectively reported, temporally primary DSM-IV disorders with the subsequent onset of suicidal behaviors. Dual-frame national sample of adolescents from the National Comorbidity Survey Replication Adolescent Supplement. Face-to-face household interviews with adolescents and questionnaires for parents. A total of 6483 adolescents 13 to 18 years of age and their parents. Lifetime suicide ideation, plans, and attempts. The estimated lifetime prevalences of suicide ideation, plans, and attempts among the respondents are 12.1%, 4.0%, and 4.1%, respectively. The vast majority of adolescents with these behaviors meet lifetime criteria for at least one DSM-IV mental disorder assessed in the survey. Most temporally primary (based on retrospective age-of-onset reports) fear/anger, distress, disruptive behavior, and substance disorders significantly predict elevated odds of subsequent suicidal behaviors in bivariate models. The most consistently significant associations of these disorders are with suicide ideation, although a number of disorders are also predictors of plans and both planned and unplanned attempts among ideators. Most suicidal adolescents (>80%) receive some form of mental health treatment. In most cases (>55%), treatment starts prior to onset of suicidal behaviors but fails to prevent these behaviors from occurring. Suicidal behaviors are common among US adolescents, with rates that approach those of adults. The vast majority of youth with suicidal behaviors have preexisting mental disorders. The disorders most powerfully predicting ideation, though, are different from those most powerfully predicting conditional transitions from ideation to plans and attempts. These differences suggest that distinct prediction and prevention strategies are needed for ideation, plans among ideators, planned attempts, and unplanned attempts.

Correlates of Suicidal Behaviors Among Asian Americans

This study examines the correlates of suicidal ideation, suicide plan and suicide attempt among Asian Americans focusing on nativity and gender. Analyses are performed on data from the National Latino and Asian American Study (N = 2095), the first ever study conducted on the mental health of a national sample of Asian Americans. The sample is comprised of adults with 998 men (47%) and 1,097 (53%) women. Analysis of weighted lifetime prevalence of suicidal behaviors revealed that U.S.-born Asian American women had higher prevelance of suicidal ideation and suicide plan than U.S.-born Asian American men and immigrant Asian American men and women. In multivariate analyses controlling for socio-demographic differences such as ethnicity, marital status and income, differences in suicidal behaviors are found only between U.S.-born women and U.S.-born men. The findings demonstrate the need to disaggregate data by immigrant status as well as socio-demographic correlates.

Lifetime prevalence of suicidal and self-injurious behaviors in a representative cohort of Slovenian adolescents with type 1 diabetes

To determine lifetime prevalence of suicidal and self-injurious behaviors in Slovenian adolescents with type 1 diabetes compared with healthy controls. Adolescents (14-19 yr) with type 1 diabetes were compared with a normative control group of healthy secondary school students by means of a self-reported questionnaire (according to Kienhorst) containing questions on demographic and family characteristics, suicidal ideation, intended suicide, attempted suicide, possible future suicide, and self-injurious behavior. Patients received the questionnaires at regular outpatient visits to the pediatric diabetes clinic, completed them in private, and returned them by mail. Questionnaires for control subjects were administered in classrooms. The responses of 126 eligible patients and 499 controls were analyzed. The control group trended toward higher lifetime prevalence of all suicidal behaviors and self-injurious behavior. The lowest prevalence of all suicidal behaviors and self-injurious behavior was reported by males with diabetes. Compared with male controls, the differences were statistically significant for suicidal ideation (p < 0.05) and intended suicide (p < 0.05). Compared with females with diabetes, the differences were statistically significant for suicidal ideation (p < 0.001), intended suicide (p < 0.01), attempted suicide (p < 0.05), and self-injurious behavior (p < 0.05). Females with diabetes reported highest prevalence of all suicidal but not self-injurious behaviors. More patients than controls reported receiving counseling the year preceding the study (p < 0.001). In the study, type 1 diabetes showed a protective effect for suicidal behavior in adolescent males but not in adolescent females. Professionals working with adolescents with type 1 diabetes should be alert to possible suicidality, especially among females.

Early trauma and lifetime suicidal behavior in a nationwide sample of Korean medical students

BackgroundNo previous study has investigated the association between early trauma and suicidal behavior in medical students. We evaluated the types of early trauma which are the most strongly associated with a lifetime history of suicidal behavior in medical students. MethodA total of 6986 medical students completed a self-administered questionnaire (response rates: 49.6% of the entire medical student body in Korea) which included lifetime suicidal behavior, stressors, and the Early Trauma Inventory Self Report-Short Form (ETISR-SF). This was used to evaluate the most serious forms of trauma experienced before the age of 18, including general trauma, physical, emotional and sexual abuse. ResultsAmong medical students, lifetime prevalence of suicidal behavior was 34.0% for those who experienced early trauma and 18.1% in those without a history of trauma (χ2=215.7, p<0.0001). Emotional abuse exhibited a higher odds ratio for lifetime suicidal behavior (OR=3.6, 95%CI=2.9–4.4) than other traumas including general trauma (OR=2.1, 95%CI=1.8–2.4), sexual (OR=2.0, 95%CI=1.5–2.8) or physical (OR=1.8, 95%CI=1.5–2.1) abuse, and current stressors including heavy stress (OR=1.5, 95%CI=1.4–1.8), poor physical health (OR=1.3, 95%CI=1.2–1.5), and poor economic status (OR=1.2, 95%CI=1.0–1.3). Emotional abuse also showed a higher odds ratio for lifetime suicidal ideation (OR=3.5, 95%CI=2.8–4.4), plan (OR=3.9, 95%CI=2.4–6.2), and attempt (OR=4.1, 95%CI=2.4–6.8) than other early traumas or stressors. In emotional abuse, a continuously cold or uncaring parental attitude exhibited a stronger association with lifetime suicidal behavior (OR=4.5, 95%CI=2.7–7.7) than other emotional abuse. ConclusionEmotional abuse, especially continuous parental emotional abuse in childhood, is significantly associated with lifetime suicidal behavior in Korean medical students.

Childhood, adolescent, and young adult predictors of suicidal behaviors: a prospective study of African Americans.

This study examined the lifetime prevalence of suicidal behaviors and their relation to social integration, depression, and aggression/substance use in a cohort of African Americans followed prospectively from first grade to age 32. Lifetime depressive moods in adulthood, lifetime use of cocaine, and frequent mobility were associated with suicidal behaviors for both males and females. For males, having been in a mother-alone or mother-absent family at age 6, childhood psychopathology, and not being married were related to suicidal behaviors. Females who reported high assault behavior in adolescence were more likely to report suicide attempts. The results suggest that social integration, depression, and aggression/drug use are important risk factors for suicidal behaviors in this African American population.
