The environment and suicide: Why suicidologists should support climate change policies

When suicidologists consider how the environment may impact suicide, they typically focus on the social and economic environment and the interpersonal environment. For the former, Lester and Yang (1997) documented how factors such as the business cycle might impact suicide rates while, many years ago, Platt (1984) showed that unemployment increased suicide rates. As for the interpersonal environment, in[…]

The need for collective awareness of attempted suicide rates in a warming climate

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[…]

Correlating heatwaves and relative humidity with suicide (fatal intentional self-harm)

Empirical evidence suggests that the effects of anthropogenic climate change, and heat in particular, could have a significant impact on mental health. This article investigates the correlation between heatwaves and/or relative humidity and suicide (fatal intentional self-harm) on a global scale. The covariance between heat/humidity and suicide was modelled using a negative binomial Poisson regression[…]

Effectiveness of mental health intervention for suicide prevention

Associations between high and low temperatures and increases in mortality and morbidity have been previously reported, yet no comprehensive assessment of disease burden has been done. Therefore, we aimed to estimate the global and regional burden due to non-optimal temperature exposure.
In part 1 of this study, we linked deaths[…]

Suicide and apparent temperature in the two capitals [sic] cities in the Iberian peninsula

Different authors have identified geographic variations in the rates of suicide. This study aims to discuss the limitations of the officially recorded suicide data and to evaluate the statistical relationship between a biometeorological index, Apparent Temperature (AT), and suicide in Madrid and Lisbon. We performed a time-series study. The association was analyzed using a quasi-Poisson[…]

Global suicide rates and climatic temperature

Global suicide rates vary by country, yet the cause of this variability has not yet been explained satisfactorily. In this study, we analyzed averaged suicide rates and annual[…]

Higher temperatures increase suicide rates in the United States and Mexico.

Linkages between climate and mental health are often theorized but remain poorly quantified. In particular, it is unknown whether the rate of suicide, a leading cause of death globally, is systematically affected by climatic conditions. Using comprehensive data from multiple decades for both the United States and Mexico, we find that suicide rates rise 0.7%[…]

Association between completed suicide and environmental temperature in a Mexican population, using the Knowledge Discovery in Database approach.

Background and objective Suicide is a worldwide health problem and climatological characteristics have been associated with suicide behavior. However, approaches such as the Knowledge Discovery in Database are not frequently used to search for an association between climatological characteristics and suicide. The aim of the present study was to assess the association between weather data[…]

Global Warming Possibly Linked to an Enhanced Risk of Suicide: Data From Italy, 1974-2003

This study explored the impact of global warming on suicide mortality, using data from Italy. Monthly data on suicide mortality & temperature were obtained for 1974-2003 & the relation between them was investigated using the Gaussian low-pass filter, linear correlation analysis, & rank analysis. For males, increasing anomalies in monthly average temperatures associated to a[…]
