  1. 自杀

一项针对加拿大青少年的最新研究支持学界“自杀传染”的假设,也就是说,青少年知道自杀事件后,不论是否了解自杀者,本人的自杀冲动也会增加。 这一成果发表在《加拿大医学协会杂志》上。在研究了2.2万多名年龄介于12岁至17岁的青少年的数据后,来自渥太华大学等机构的研究者们发现,12岁至13岁的少年在得悉自杀事件后,本人产生自杀想法或行动的风险增加了4倍多。

研究人员表示,通过研究还发现,“自杀传染”的效果会随着青少年年龄的增加而递减。在14岁至15岁的人群中,“自杀传染”风险为3倍,而在16岁至17岁的人群中,该风险为两倍多。另外,本人是否认识自杀者并不会对这种相关性产生显着影响。

研究人员表示,当自杀事件发生后,死者家属、媒体可能会对自杀行为美化或浪漫化,这些做法会产生危险后果,因为相对脆弱的青少年群体可能产生错误想法,认为自杀可以解决某些问题。

研究者说,当校园中出现自杀事件,应该优先针对年龄小的群体进行危机干预,避免让青少年“暴露”在自杀新闻中。(生物谷Bioon.com)

Association between exposure to suicide and suicidality outcomes in youth

Sonja A. Swanson, Ian Colman

Background: Ecological studies support the hypothesis that suicide may be "contagious" (i.e., exposure to suicide may increase the risk of suicide and related outcomes). However, this association has not been adequately assessed in prospective studies. We sought to determine the association between exposure to suicide and suicidality outcomes in Canadian youth.

Methods: We used baseline information from the Canadian National Longitudinal Survey of Children and Youth between 1998/99 and 2006/07 with follow-up assessments 2 years later. We included all respondents aged 12–17 years in cycles 3–7 with reported measures of exposure to suicide.

Results: We included 8766 youth aged 12–13 years, 7802 aged 14–15 years and 5496 aged 16–17 years. Exposure to a schoolmate's suicide was associated with ideation at baseline among respondents aged 12–13 years (odds ratio [OR] 5.06, 95% confidence interval [CI] 3.04–8.40), 14–15 years (OR 2.93, 95% CI 2.02–4.24) and 16–17 years (OR 2.23, 95% CI 1.43–3.48). Such exposure was associated with attempts among respondents aged 12–13 years (OR 4.57, 95% CI 2.39–8.71), 14–15 years (OR 3.99, 95% CI 2.46–6.45) and 16–17 years (OR 3.22, 95% CI 1.62–6.41). Personally knowing someone who died by suicide was associated with suicidality outcomes for all age groups. We also assessed 2-year outcomes among respondents aged 12–15 years: a schoolmate's suicide predicted suicide attempts among participants aged 12–13 years (OR 3.07, 95% CI 1.05–8.96) and 14–15 years (OR 2.72, 95% CI 1.47–5.04). Among those who reported a schoolmate's suicide, personally knowing the decedent did not alter the risk of suicidality.

Interpretation: We found that exposure to suicide predicts suicide ideation and attempts. Our results support school-wide interventions over current targeted interventions, particularly over strategies that target interventions toward children closest to the decedent.
