Suicide is a serious public health problem around the world. Since the nineteenth century, the impact of socio-environmental factors on suicide has attracted much public attention, especially in the context of global climate change. We have performed a retrospective correlation study that analyzes the demographic pattern of suicide in Cantabria, a northern coastland region of Spain. Moreover, we have created a multivariable binomial regression model to study the relationship between suicide and environmental factors (atmospheric pollutants and meteorological variables) among January 1, 2000, and December 31, 2013 in the province. During the 14-year study period, there was a suicide annual incidence of 4.9 cases per 100,000 population in Cantabria. The incidence was highest in adults aged 70-74 years old (11.8 per 100,000 population). The most common method group of suicide was hanging, strangulation and suffocation, accounting for 49.3% of all suicide deaths. When correlating suicide and meteorological variables, a statistically significant association was found with the level of cloudiness (p = 0.007). According to our results, an increase of one eighth of sky cloud-cover correlated to a 7% increase in total deaths by suicide and the association was especially strong during spring.
自杀是全球范围内一个严重的公共卫生问题。自19世纪以来，社会环境因素对自杀的影响就备受公众关注，尤其是在全球气候变化的背景下。我们进行了一项回顾性相关性研究，分析了西班牙北部沿海地区坎塔布里亚的自杀人口统计学模式。此外，我们创建了一个多变量二项回归模型，以研究2000年1月1日至2013年12月31日该省自杀与环境因素（大气污染物和气象变量）之间的关系。在为期14年的研究期间，坎塔布里亚的自杀年发病率为每10万人中有4.9例。发病率在70 - 74岁的成年人中最高（每10万人中有11.8例）。最常见的自杀方式是上吊、勒死和窒息，占所有自杀死亡人数的49.3%。在将自杀与气象变量进行相关性分析时，发现与云量水平存在统计学上的显著关联（p = 0.007）。根据我们的研究结果，天空云量增加八分之一与自杀总死亡人数增加7%相关，且这种关联在春季尤为明显。
