The purpose of the study was to examine the association of suicide rates, firearm ownership, political conservatism, religious integration at the state level, and individual suicide risk. Social structural and social learning and social integration theories were theoretical frameworks employed. It was hypothesized that higher suicide rates, higher state firearm availability, and state conservatism elevate individual suicide risk.
Data were pooled from the Multiple Cause of Death Files. Multilevel logistic regression models were fitted to all deaths occurring in 2000 through 2004 by suicide.
The state suicide rate significantly elevated individual suicide risk (AOR = 1.042, CI = 1.037, 1.046). Firearm availability at the state level was associated with significantly higher odds of individual suicide (AOR = 1.004, CI = 1.003, 1.006). State political conservatism elevated the odds of individual suicides (AOR = 1.005, CI = 1.003, 1.007), while church membership at the state level reduced individual odds of suicide (AOR = 0.995, CI = 0.993, 0.996). The results held even after controlling for socioeconomic and demographic variables at the individual level.
It was concluded that the observed association between individual suicide odds and national suicide rates, and firearm ownership cannot be discounted. Future research ought to focus on integrating individual level data and contextual variables when testing for the impact of firearm ownership. Support was found for social learning and social integration theories.
本研究旨在探讨自杀率、枪支拥有量、政治保守主义、州级宗教融合与个体自杀风险之间的关系。采用社会结构理论、社会学习理论和社会整合理论作为理论框架。研究假设更高的自杀率、更高的州级枪支可获得性和州级保守主义会增加个体自杀风险。
数据来自多原因死亡档案。通过多水平逻辑回归模型,对 2000 年至 2004 年所有自杀死亡者进行拟合。
州自杀率显著增加了个体自杀风险(AOR=1.042,CI=1.037,1.046)。州级枪支可获得性与个体自杀的高几率显著相关(AOR=1.004,CI=1.003,1.006)。州级政治保守主义增加了个体自杀的几率(AOR=1.005,CI=1.003,1.007),而州级教会成员身份降低了个体自杀的几率(AOR=0.995,CI=0.993,0.996)。即使在控制了个体层面的社会经济和人口变量后,结果仍然成立。
可以得出结论,观察到的个体自杀几率与国家自杀率和枪支拥有量之间的关系不容忽视。未来的研究应该集中在整合个体层面的数据和背景变量,以检验枪支拥有量的影响。社会学习和社会整合理论得到了支持。
