The relationship between neighborhood environments and suicide has not been well studied. In the present study, relations between suicidal ideation and social and physical environments were investigated in Korean adults.
This nationwide cross-sectional study was conducted using data from the 2013 Korea Community Health Survey. The final analysis included 221,038 individuals aged ≥ 19 years. A multivariate regression model was used to examine the independent effects of environments on suicidal ideation.
Approximately 9.4% of participants had experienced suicidal ideation. Stepwise multivariate regression analysis showed that trusting neighbors and all five physical environments were independently associated with suicidal ideation. As regards physical environments, relations with suicidal ideation varied across subgroups: satisfaction with overall safety was to be strongly and consistently related to less suicidal ideation.
Causality and the impact of unmeasured confounders were not addressed.
Neighborhood environments may reduce suicidal ideation.
邻里环境与自杀之间的关系尚未得到充分研究。在本研究中，我们调查了韩国成年人自杀意念与社会和物理环境之间的关系。
本全国性横断面研究使用了 2013 年韩国社区健康调查的数据。最终分析包括 221038 名年龄≥19 岁的个体。采用多变量回归模型来检验环境对自杀意念的独立影响。
约有 9.4%的参与者曾有过自杀意念。逐步多变量回归分析显示，信任邻居和所有五个物理环境都与自杀意念独立相关。就物理环境而言，与自杀意念的关系因亚组而异：对整体安全性的满意度与较低的自杀意念密切相关。
未解决因果关系和未测量混杂因素的影响。
邻里环境可能会降低自杀意念。
