“…More recently, studies showed that the more sunshine there is, the fewer suicides there are (Thorson and Kasworm 1984;Linkowski et al 1992), while Maes et al (1994) and Salib and Gray (1997) found the opposite to be true. In general, for every study that has correlated some element of the weather with some response indicative of emotional state, another has found opposite or contradictory results.…”

Weather and emotional state: a search for associations between weather and calls to telephone counseling services

Previous research has revealed that an emotional response to weather might be indicated by calls to telephone counseling services. We analyzed call frequency from such "hotlines", each serving communities in a major metropolitan area of the United States (Detroit, Washington DC, Dallas and Seattle). The periods examined were all, or parts of, the years 1997 and 1998. Associations with subjectively derived synoptic weather types for all cities except Seattle, as well as with individual weather elements [cloudiness (sky cover), precipitation, windspeed, and interdiurnal temperature change] for all four cities, were investigated. Analysis of variance and t-tests (significance of means) were applied to test the statistical significance of differences. Although statistically significant results were obtained in scattered instances, the total number was within that expected by chance, and there was little in the way of consistency to these associations. One clear exception was the increased call frequency during destructive (severe) weather, when there is obvious concern about the damage done by it.

“…29 Muchas otras explicaciones se han propuesto, ya que el patrón en cuanto al suicidio en el hombre durante los meses cálidos ha sido ampliamente reportado. 6,[30][31][32][33] Dentro de estas posibles explicaciones, la más plausible para BCS es la acción del calor sobre las vías que integran la percepción ambiental, información que es controlada en los circuitos de la memoria emocional, para de ahí pasar a la toma de decisiones. Las alteraciones funcionales de este circuito, aunadas a factores ambientales adversos, como el calor, parecen promover el acto suicida.…”

Introducción. Durante las últimas décadas se ha podido apreciar un cambio en las variables climáticas, en especial en la temperatura ambiental. Hay evidencias que asocian el aumento de la temperatura ambiental con el incremento en las tasas de mortalidad por suicidio. Objetivo. Evaluar la relación entre la tasa de suicidio y la temperatura ambiental en Baja California Sur (BCS) durante los años 1985-2008. Método. Los datos de suicidio fueron obtenidos de las bases de Mortalidad del INEGI de 1985-2008. Se tabularon los registros con códigos: E950-E959 CIE-9 y X60-X84, Y87.0 CIE-10 para BCS. En el análisis climático se usaron las temperaturas máximas de 1985 al 2008 para BCS del Extractor Rápido de Información Climatológica (ERIC III). Para evaluar la tendencia, se utilizaron modelos de regresión lineal y cuadráticos. Los modelos lineales generalizados (GLM) se utilizaron para evaluar el efecto de las variables ambientales sobre la tasa de suicidios, con una significancia de p=0.05. Resultados. Un total de 582 suicidios ocurrieron en BCS de 1985 a 2008. Las mujeres representaron el 9% (53), con tasa anual promedio de 1.6/100 000. Los hombres 91% (529), con tasa promedio anual de 16.3/100 000. La tendencia de incremento anual se explico con modelos lineales simples y cuadráticos en ambas temporadas. En los meses cálidos el modelo cuadrático explico mejor dicho incremento (R2=0.64 p<0.01). La temperatura se correlaciono positivamente con la tasa en ambas temporadas (p<0.01). Se generaron dos modelos GLM predictivos por temporada. Discusión. En este trabajo se observo una posible relación entre el incremento de la temperatura ambiental y el número de suicidios registrados durante 24 años en BCS. Esta relación se encuentra bien definida en los meses cálidos, pero con una tendencia en aumento para los meses fríos.

“…This means that beside some anthropological and biological theoretical perspectives, a wide range of competitive hypothesis could be put on the local empirical background. Thus, in addition to classical Durkheim and Morselli's theoretical positions which try to explain suicide regional variations in XIX century Europe, the Belarusian example is fit to the number of modern hypothesis operating with climatic (29,30), sociocultural and behavioral factors (31)(32)(33). Simultaneously, the question is raised about the projection of the same factors effect in genesis of alcohol psychosis regional differences.…”

Objective. Epidemiological evidence suggests that rates of suicide mortality vary noticeably between the regions in Belarus with the regular spatial pattern in suicide distribution. The present study considers the effect of regional alcohol consumption as a factor responsible for regional variations in suicide rates.Methods. The cross-sectional time series analysis of suicide and alcohol psychoses (as a proxy for alcohol consumption) rates by the regions of Belarus between 1990 and 2010 was made.Results. In general, the regional variations of suicide and alcohol psychoses incidence rates have a similar spatial regularity, meaning that the regions with a high suicide rate also have a high alcohol psychoses incidence rate.Conclusions. The findings on spatial relationship between suicide and alcohol psychoses incidence rates seem to support the hypothesis that considers the regional pattern of alcohol consumption as a factor responsible for suicide rate regional variations.

Weather conditions and fatal self-harm in North Cheshire 1989–1993

Abstract: Weather may influence the occurrence of FSH, probably interacting with biological and social variables. The rate of FSH death appears to be positively related to fine weather conditions, during early summer, and not to extreme weather conditions as previously reported.
