Approximately 30% of suicides in New York City are the result of jumping from a height. After describing jumping suicides and jumping sites, we used polychotomous logistic regression to compare the characteristics of suicides by jumping to those of individuals committing suicide by hanging, ingestion, or shooting. Method used was significantly associated with sociodemographics, occupation, and mental health status, even after adjustment for individual access to the means of committing suicide. Our finding of an independent association between personal characteristics and method used provides strong evidence for the hypothesis that controlling access to an agent of suicide can influence overall suicide rates, at least in the short term. Study results support the introduction of preventive programs to control access to commonly employed agents of suicide.
在纽约市，约30%的自杀事件是由高处跳下导致的。在描述了跳楼自杀事件及跳楼地点后，我们使用多分类逻辑回归来比较跳楼自杀者与通过上吊、吞服药物或枪击自杀者的特征。即便在对个人获取自杀手段的情况进行调整之后，所使用的自杀方法仍与社会人口统计学、职业及心理健康状况显著相关。我们发现个人特征与所使用的自杀方法之间存在独立关联，这为以下假设提供了有力证据：控制自杀手段的获取至少在短期内能够影响总体自杀率。研究结果支持引入预防项目以控制对常用自杀手段的获取。
