自杀是一个严重的全球公共卫生问题，自2003年以来，韩国的自杀率一直是经济合作与发展组织（OECD）成员国中最高的。然而，大多数以前的韩国自杀研究在调查各种社会环境因素使用长期的全国性数据的局限性。因此，本研究使用11年的全国纵向数据，考察了各种社会环境特征与地区自杀率的关系。我们使用了韩国229个行政区的区级年龄标准化自杀率和总共12个年度社会环境特征，这些特征代表了社会经济、人口、城市化、一般健康行为和其他环境特征。贝叶斯层次模型与集成拉普拉斯近似（INLA）被用来检查自杀率和社会环境指标之间的时空关联。在总人口中，“65岁及以上人口中有资格领取基本养老金的百分比”、“该地区空置房屋的百分比”、“离婚的百分比”、“单身老人家庭的百分比”、“独立房屋的百分比”、“目前吸烟的百分比”和“肥胖人口的百分比”等指标与自杀率呈正相关。相比之下，“经常参加宗教活动的人的百分比”与自杀率呈负相关。这些社会环境特征和自杀率之间的关联在男性和城市化程度较高的地区，一般比在女性和城市化程度较低的地区更具有统计学意义;然而，根据所研究的社会环境特征变量，不同年龄组之间的关联不同。这项研究调查了韩国社会环境对自杀率的复杂作用，并揭示了较高的自杀率与较低的社会经济地位，体育锻炼和宗教活动，以及较高的社会隔离和吸烟行为有关。我们的研究结果可以用于制定有针对性的自杀预防政策。在线版本包含补充材料，可通过10.1186/s12889-022-12843-4获得。
Suicide is a serious worldwide public health concern, and South Korea has shown the highest suicide rate among Organisation for Economic Co-operation and Development (OECD) countries since 2003. Nevertheless, most previous Korean studies on suicide had limitations in investigating various social environment factors using long-term nationwide data. Thus, this study examined how various social environment characteristics are related to the suicide rate at the district-level, using nationwide longitudinal data over 11 years. We used the district-level age-standardized suicide rate and a total of 12 annual social environment characteristics that represented socioeconomic, demographic, urbanicity, general health behaviors, and other environmental characteristics from 229 administrative districts in South Korea. A Bayesian hierarchical model with integrated Laplace approximations (INLA) was used to examine the spatiotemporal association between the rate of suicide and the social environment indicators selected for the study. In the total population, the indicators “% of population aged 65 and older eligible for the basic pension”, “% vacant houses in the area”, “% divorce”, “% single elderly households”, “% detached houses”, “% current smokers”, and “% of population with obesity” showed positive associations with the suicide rate. In contrast, “% of people who regularly participated in religious activities” showed negative associations with suicide rate. The associations between these social environment characteristics and suicide rate were generally more statistically significant in males and more urbanized areas, than in females and less urbanized areas; however, associations differed amongst age groups, depending on the social environment characteristic variable under study. This study investigated the complex role of social environments on suicide rate in South Korea and revealed that higher suicide rates were associated with lower values of socioeconomic status, physical exercise, and religious activities, and with higher social isolation and smoking practice. Our results can be used in the development of targeted suicide prevention policies. The online version contains supplementary material available at 10.1186/s12889-022-12843-4.
