To identify weather factors associated with an increased risk of suicide. In a number of prior studies an influence of meteorological conditions on the incidence of suicide or attempted suicide has been suggested.
Official data on the suicide cases of the state of Tyrol, Austria, assessed over a period of 6 years (n = 702) were correlated with a number of meteorological factors assessed at eight weather stations.
The risk of committing suicide was significantly higher on days with high temperatures, low relative humidity or a thunderstorm and on days following a thunderstorm. The multiple logistic regression analysis left "temperature" and "thunderstorm on the preceding day" as significant factors, even after adjustment for sociodemographic and geographical variables.
Within the interaction of psychological and environmental influences in the development of suicidal ideation and behaviour, specific meteorological conditions may additionally contribute to the risk of suicide in predisposed individuals.
确定与自杀风险增加相关的天气因素。在一些先前的研究中，有人提出气象条件对自杀或自杀未遂发生率有影响。
奥地利蒂罗尔州6年期间评估的702例自杀病例的官方数据，与8个气象站评估的若干气象因素相关联。
在高温、低相对湿度或雷暴天气以及雷暴过后的日子里，自杀风险显著更高。多元逻辑回归分析显示，即使在对社会人口统计学和地理变量进行调整后，“温度”和“前一天有雷暴”仍是显著因素。
在自杀观念和行为发展过程中的心理与环境影响的相互作用中，特定的气象条件可能会额外增加易患个体的自杀风险。
