估计每个调查国家的自杀意念和自杀意念的患病率，并检查相关风险因素的跨国差异。我们分析了32个国家参加2003-2012年全球校本健康调查的13-17岁学生的数据，其中29个是低收入和中等收入国家。我们使用随机效应荟萃分析来生成区域和总体汇总估计值。多变量逻辑回归用于估计相关危险因素的风险比。根据调整后的风险比和每个暴露水平内决定因素的流行率估计人群归因分数。在所有国家中，合并的12个月自杀意念患病率为16.2%（95%置信区间，CI：15.6至16.7），（95% CI：11.7至12.7），女性中有计划的想法为8.3%（95% CI：7.9至8.7），男性中为5.8%（95% CI：5.5至6.1）。在世卫组织美洲区域，女性的自杀意念高于男性，估计患病率为1.70（95% CI：1.60至1.81），而在世卫组织非洲区域，这一比率为1.04（95% CI：0.98至1.10）。在大多数国家，与自杀意念相关的因素包括欺凌和身体暴力的经历、孤独、父母支持有限以及饮酒和吸烟。青少年自杀行为的流行率因国家而异，但在所有区域和大多数国家都出现了一套一致的自杀行为风险因素。
To estimate prevalence of suicidal ideation and suicidal ideation with a plan in each surveyed country and to examine cross-national differences in associated risk factors. We analysed data of students aged 13–17 years who participated in the 2003–2012 Global School-based Health Surveys in 32 countries, of which 29 are low- and middle-income. We used random effects meta-analysis to generate regional and overall pooled estimates. Multivariable logistic regression was used to estimate risk ratios for the associated risk factors. Population attributable fractions were estimated based on adjusted risk ratios and the prevalence of the determinants within each exposure level. Across all countries, the pooled 12-month prevalence of suicide ideation were 16.2% (95% confidence interval, CI: 15.6 to 16.7) among females and 12.2% (95% CI: 11.7 to 12.7) among males and ideation with a plan were 8.3% (95% CI: 7.9 to 8.7) among females and 5.8% (95% CI: 5.5 to 6.1) among males. Suicide ideation in the WHO Region of the Americas was higher in females than males, with an estimated prevalence ratio of 1.70 (95% CI: 1.60 to 1.81), while this ratio was 1.04 (95% CI: 0.98 to 1.10) in the WHO African Region. Factors associated with suicidal ideation in most countries included experiences of bullying and physical violence, loneliness, limited parental support and alcohol and tobacco use. The prevalence of adolescent suicidal behaviours varies across countries, yet a consistent set of risk factors of suicidal behaviours emerged across all regions and most countries.
