Background: Climate factors may offer a stronger explanation of the variations in suicide rates compared with economic variables, even in the case of patients admitted involuntarily. Aims: We assessed the role of temperature as a determinant of the increased prevalence of suicide attempts (SA). Method: The sample comprised all cases of hospitalization for SA at the Psychiatric Clinic of the IRCCS Ospedale Policlinico San Martino between August 2013 and July 2018. For ambient temperature, data were provided by the Meteorological Observatory of the University of Genoa. Results: We noted a peak in suicides that was typically found in late spring and early summer due to global warming. Limitations: Other environmental/psychological factors contributing to the onset of an acute clinical event were not considered. The cross-sectional design of the study is another limitation. Conclusion: Further studies are needed to clarify the impact of climatic factors on suicide behavior and implement early intervention and preventive strategies for mental health.

在变暖的气候中需要对自杀率的集体意识。

背景：即使是非自愿入院的患者，气候因素也可能提供比经济变量更能说明自杀率变化的解释。目的：我们评估了温度作为决定自杀未遂（SA）患病率上升的因素。方法：样本包括2013年8月至2018年7月在IRCCS Ospedale Policlinico San Martino精神病学诊所住院的所有SA病例。对于环境温度，数据由热那亚大学气象台提供。结果：我们注意到，由于全球变暖，自杀高峰通常发生在春季末和初夏。局限性：未考虑导致急性临床事件发作的其他环境/心理因素。研究的横截面设计是另一个限制。结论：需要进一步研究以阐明气候因素对自杀行为的影响，并为精神健康实施早期干预和预防策略。
