背景自杀是全世界死亡的主要原因；然而，自杀的直接前兆——自杀意念、计划和企图——的流行率和危险因素并不为人所知，特别是在低收入和中等收入国家。目的报告17个国家自杀行为的流行率和危险因素。方法总共对84850名成年人进行了关于自杀行为以及社会人口和精神危险因素的采访。结果 自杀意念、计划和企图的终生患病率分别为 9.2% (s.e.=0.1)、3.1% (s.e.=0.1) 和 2.7% (s.e.=0.1)。在所有国家中，60% 从构思到计划和尝试的转变发生在构思开始后的第一年内。一致的跨国危险因素包括女性、年轻、受教育程度较低、未婚和患有精神障碍。有趣的是，最强的诊断风险因素在高收入国家是情绪障碍，但在低收入和中等收入国家是冲动控制障碍。结论自杀行为的流行率存在跨国差异，但这些行为的特征和风险因素具有很强的一致性。这些发现对于自杀行为的预测和预防具有重要意义。利益声明无。致谢中详细说明了资助情况。
BackgroundSuicide 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.AimsTo report on the prevalence and risk factors for suicidal behaviours across 17 countries.MethodA 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.ConclusionThere 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 interestsNone. Funding detailed in Acknowledgements.
