Suicide has a large public health impact. Although effective interventions exist, the many people at risk for suicide cannot access these interventions. Exercise interventions hold promise in terms of reducing suicide because of their ease of implementation. While exercise reduces depression, and reductions in depressive symptoms are linked to reduced suicidal ideation, no studies have directly linked exercise and suicide risk. The current study examined this association, including potential mediators (i.e., sleep disturbance, posttraumatic stress symptoms, and depression), in a sample of Veterans. SEM analyses revealed that exercise was directly and indirectly associated with suicide risk. Additionally, exercise was associated with fewer depressive symptoms and better sleep patterns, each of which was, in turn, related to lower suicide risk.
自杀对公众健康有重大影响。尽管存在有效的干预措施，但许多有自杀风险的人无法获得这些干预措施。运动干预在降低自杀风险方面有很大的希望，因为它们易于实施。虽然运动可以减轻抑郁，而抑郁症状的减轻与自杀意念的减少有关，但没有研究直接将运动与自杀风险联系起来。本研究在退伍军人样本中检验了这种关联，包括潜在的中介因素（即睡眠障碍、创伤后应激症状和抑郁）。结构方程模型分析显示，运动与自杀风险直接和间接相关。此外，运动与较少的抑郁症状和更好的睡眠模式相关，而这些又与较低的自杀风险相关。
