Suicidal ideations (SI), also known as suicidal thoughts, refer to impulses, desires, and obsessions related to death. Prevalence of suicidal ideation was 14 percent. The current study assumed that identifying the true predictors of SI would allow for a greater understanding of suicide risk.
In this cross-sectional population-based study, 17,644 residents aged from 15 to 90 years were selected through a multi-stage sampling method from 22 districts of Tehran. Using hypothesized causal models, the pathways through which various variables influenced the components of SI were identified. Also, the applicability of the compensatory and risk-protective models of resiliency for the prediction of SI was tested by using the interaction multiple regression analyses.
SI was experienced by 13.44% of the study population. SI was more prevalent with individuals between the ages of 15 to 24. There are no differences between men and women when covariate analysis is used. The significant predictions by anxiety and physical activity (moderate) indicate support for the compensatory model for male and female, while the significant prediction by those indicates support for the risk-protective model for females.
PA would both lessen the detrimental impact of anxiety on suicidal thoughts and potentially reduce the probability of SI. It's important to develop and evaluate PA-enhancing treatments, especially for woman who are experiencing anxiety.
自杀意念（SI），又称自杀念头，是指与死亡相关的冲动、欲望和困扰。自杀意念的患病率为 14%。本研究假设，确定 SI 的真正预测因素将有助于更好地了解自杀风险。
在这项横断面、基于人群的研究中，通过多阶段抽样方法从德黑兰的 22 个区选择了 17644 名年龄在 15 至 90 岁的居民。使用假设的因果模型，确定了各种变量通过哪些途径影响 SI 的组成部分。此外，还通过交互多重回归分析测试了弹性的补偿和风险保护模型对 SI 预测的适用性。
研究人群中有 13.44%的人经历过 SI。15 至 24 岁的个体中 SI 更为普遍。在进行协变量分析时，男性和女性之间没有差异。焦虑和身体活动（中度）的显著预测表明，补偿模型对男性和女性均有支持，而这些因素的显著预测表明，风险保护模型对女性有支持。
PA 既可以减轻焦虑对自杀念头的不利影响，又可以降低 SI 的可能性。开发和评估增强 PA 的治疗方法非常重要，特别是对正在经历焦虑的女性。
