Seasonal changes and climatic factors like ambient temperature, sunlight duration and rainfall can influence suicidal behavior.
This study analyses the relationship between seasonal changes and climatic variations and suicide attempts in 2131 young patients in Istanbul, Turkey.
In our study sample, there was an association between suicide attempts in youths and seasonal changes, as suicide attempts occurred most frequently during summer in females as well as in males. Furthermore, there was a positive correlation between the mean temperature over the past 10 days and temperature at the index day and suicide attempts in females. After seasonality effects were mathematically removed, the mean temperature 10 days before a suicide attempt remained significant in males only, indicating a possible short-term influence of temperature on suicide attempts.
This study shows an association between suicide attempts of young people and climatic changes, in particular temperature changes as well as seasonal changes. Therefore, the influence of seasonal changes and climatic factors on young suicide attempters should get more attention in research to understand the biopsychosocial mechanisms playing a role in suicide attempts of young people. As suicide attempts most frequently occur in young people, further research is of considerable clinical importance.
季节性变化和环境温度、日照时间和降雨量等气候因素会影响自杀行为。
本研究分析了 2131 名土耳其伊斯坦布尔年轻患者中季节性变化和气候变异与自杀企图之间的关系。
在我们的研究样本中，青少年自杀企图与季节性变化有关，女性和男性自杀企图最常发生在夏季。此外，过去 10 天的平均温度与指数日的温度与女性自杀企图呈正相关。在数学去除季节性影响后，仅在男性中，自杀企图前 10 天的平均温度仍具有显著意义，表明温度对自杀企图可能存在短期影响。
本研究表明，年轻人的自杀企图与气候变化有关，特别是温度变化以及季节性变化。因此，季节性变化和气候因素对年轻自杀未遂者的影响应在研究中得到更多关注，以了解在年轻人自杀企图中起作用的生物心理社会机制。由于自杀企图最常发生在年轻人中，因此进一步的研究具有相当大的临床意义。
