    Cross-national prevalence and risk factors for suicidal ideation, plans and attempts
    (ROYAL COLLEGE OF PSYCHIATRISTS, BRITISH JOURNAL OF PSYCHIATRY 17 BELGRAVE SQUARE, LONDON SW1X 8PG, ENGLAND, 2008) Nock, Matthew K.; Borges, Guilherme; Bromet, Evelyn J.; Alonso, Jordi; Angermeyer, Matthias; Beautrais, Annette; Bruffaerts, Ronny; Chiu, Wai Tat; De Girolamo, Giovanni; Gluzman, Semyon; De Graaf, Ron; Gureje, Oye; Haro, Josep Maria; Huang, Yueqin; Karam, Elie; Kessler, Ronald C.; Lepine, Jean Pierre; Levinson, Daphna; Medina-Mora, María Elena; Ono, Yutaka; Posada-Villa, José; Williams, David; Harvard Univ, Dept Psychol, Cambridge, MA 02138 USA; nock@wjh.harvard.edu
    Background: Suicide is a leading cause of death worldwide; however, the prevalence and risk factors for the immediate precursors to suicide - suicidal ideation, plans and attempts - are not well-known, especially in low- and middle-income countries. Aims: To report on the prevalence and risk factors for suicidal behaviours across 17 countries. Method: A total of 84850 adults were interviewed regarding suicidal behaviours and socio-demographic and psychiatric risk factors. Results: The cross-national lifetime prevalence of suicidal ideation, plans, and attempts is 9.2% (s.e.=0.1), 3.1% (s.e.=0.1), and 2.7% (s.e.=0.1). Across all countries, 60% of transitions from ideation to plan and attempt occur within the first year after ideation onset. Consistent cross-national risk factors included being female, younger, less educated, unmarried and having a mental disorder. interestingly, the strongest diagnostic risk factors were mood disorders in high-income countries but impulse control disorders in low- and middle-income countries. Conclusion: There is cross-national variability in the prevalence of suicidal behaviours, but strong consistency in the characteristics and risk factors for these behaviours. These findings have significant implications for the prediction and prevention of suicidal behaviours. Declaration of interests: None. Funding detailed in Acknowledgements.

    Lifetime prevalence and age-of-onset distributions of mental disorders in the World Health Organization's World Mental Health Survey Initiative

    Data are presented on the lifetime prevalence, projected lifetime risk, and age-of-onset distributions of mental disorders in the World Health Organization (WHO)'s World Mental Health (WMH) Surveys. Face-to-face community surveys were conducted in seventeen countries in Africa, Asia, the Americas, Europe, and the Middle East. The combined numbers of respondents were 85,052. Lifetime prevalence, projected lifetime risk and age of onset of DSM-IV disorders were assessed with the WHO Composite International Diagnostic Interview (CIDI), a fully-structured lay administered diagnostic interview. Survival analysis was used to estimate lifetime risk. Median and inter-quartile range (IQR) of age of onset is very early for some anxiety disorders (7-14, IQR: 8-11) and impulse control disorders (7-15, IQR: 11-12). The age-of-onset distribution is later for mood disorders (29-43, IQR: 35-40), other anxiety disorders (24-50, IQR: 31-41), and substance use disorders (18-29, IQR: 21-26). Median and IQR lifetime prevalence estimates are: anxiety disorders 4.8-31.0% (IQR: 9.9-16.7%), mood disorders 3.3-21.4% (IQR: 9.8-15.8%), impulse control disorders 0.3-25.0% (IQR: 3.1-5.7%), substance use disorders 1.3-15.0% (IQR: 4.8-9.6%), and any disorder 12.0-47.4% (IQR: 18.1-36.1%). Projected lifetime risk is proportionally between 17% and 69% higher than estimated lifetime prevalence (IQR: 28-44%), with the highest ratios in countries exposed to sectarian violence (Israel, Nigeria, and South Africa), and a general tendency for projected risk to be highest in recent cohorts in all countries. These results document clearly that mental disorders are commonly occurring. As many mental disorders begin in childhood or adolescents, interventions aimed at early detection and treatment might help reduce the persistence or severity of primary disorders and prevent the subsequent onset of secondary disorders.
