Abstract
Background and objectives

Certain air pollutants are associated with mental health conditions, like cognitive decline, depression and suicide. The aim of the study was to assess the relationship between long-term exposure to airborne concentrations of particulate matter (PM), sulphur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), benzo[a]pyrene (BaP) and suicide rates, suicide attempts and suicide attempts among people with mental disorder.

Methods

The data used covered the years 2013–2016 of 27 regions in Poland, came from the Chief Inspectorate for Environmental Protection, the Provincial Police Headquarters and the Central Statistical Office. Univariate and multivariate linear regression analyses had been performed.

Results

Results of the study indicate that ozone is correlated with the rate of suicide attempts, the rate of total suicides and attempts at suicide attempts among people with mental disorder (r = 0.548, p < 0.001; r = 0.371, p < 0.01; r = 0.422, p < 0.01, respectively). Independent predictors of suicide attempts were high ozone concentration (β = 0.00216, p < 0.001), high feminisation and a small number of beneficiaries of environmental social welfare per 10,000 population. Completed suicide rate was associated with increased air concentrations of PM10 particulate matter (b = 0.0003, p = 0.001; β = 0.003, p < 0.001), a high number of employees and a high level of total pollutant emissions (β = 0.00027, p = 0.031). Finally, suicide attempts among people with psychiatric disorder were linked to high ozone concentration (b = 0.0005; p < 0.001; β = 0.0003; p = 0.004) and low SO2 concentration (b = − 0.0011; p < 0.001; β = − 0.0008; p = 0.002).

Conclusions

Air pollutions' impact on suicidality is comparable to some adverse demographic factors and it should be considered as a strong predictor for suicidal behaviour.

Resumen
Antecedentes y objetivos

Algunos contaminantes del aire están asociados a ciertos estados de salud mental, tales como deterioro cognitivo, depresión y suicidio. El objetivo del estudio fue evaluar la relación entre la exposición a largo plazo a las concentraciones aerotransportadas de materia particulada (PM), dióxido de sulfuro (SO2), dióxido de nitrógeno (NO2), ozono (O3), benzo[a]pireno (BaP) y tasas de suicidio, intentos de suicidio y tentativas de suicidio entre las personas con trastornos mentales.

Métodos

Los datos utilizados abarcaron los años 2013 a 2016 en 27 regiones de Polonia, y procedieron del Cuerpo de Inspectores de Protección Medioambiental, el Cuartel General de la Policía Provincial y la Oficina Estadística Central. Se realizaron análisis de regresión lineal univariante y multivante.

Resultados

Los resultados del estudio indican que el ozono está correlacionado con la tasa de intentos de suicidio, la tasa de suicidios totales y las tentativas de suicidio entre las personas con trastornos mentales (r = 0,548, p < 0,001; r = 0,371, p < 0,01; r = 0,422 y p < 0,01, respectivamente). Los factores predictivos independientes de los intentos de suicidio fueron la alta concentración de ozono (β = 0,00216, p < 0,001), la alta feminización y el pequeño número de beneficiarios del bienestar social medioambiental por cada 10.000 habitantes. La tasa de suicidios completados se asoció al incremento de las concentraciones en aire de materia particulada PM10 (b = 0,0003, p = 0,001; β = 0,003, p < 0,001), el elevado número de empleados y el alto nivel de emisiones de contaminantes totales (β = 0,00027, p = 0,031). Por último, las tentativas de suicidio entre las personas con trastornos psiquiátricos estuvieron vinculadas a la alta concentración de ozono (b = 0,0005; p < 0,001; β = 0,0003; p = 0,004) y la baja concentración de SO2 (b = − 0,0011; p < 0,001; β = −0,0008; p = 0,002).

Conclusiones

El impacto de los contaminantes del aire en la tendencia suicida es comparable a algunos factores demográficos adversos, debiendo considerarse un fuerte factor predictivo del comportamiento suicida
