“…In spite of the limitations, to the best of our knowledge only one other study has reported on the relationship between climate and suicides in Mexico, and that was limited to one state in the country [ 78 ]. Considering the nature of the phenomenon, a strength of this work is the presentation of the wavelet analysis as a suitable option because of its usefulness in analyzing long time series, especially when mathematical properties change over time.…”

IntroductionSuicide is a complex and multifactorial phenomenon with growing importance to public health. An increase in its occurrence has been observed in Mexico over the past 10 years. The present article analyzes the secular trend in suicide at the national level between the years 2000 and 2013.Materials and MethodsAll suicides during the study period (n = 64,298, of which 82.11% were men) were characterized using a spectral decomposition of the time series and a wavelet analysis to evaluate the effect of seasonal changes, type of area (urban versus rural) and sex.ResultsA seasonal pattern was observed with statistically significant cycles every 12 months, where peaks were identified in May but only for men in urban zones as of the year 2007. In addition, specific days of the year were found to have a higher frequency of suicides, which coincided with holidays (New Year, Mother’s Day, Mexican Independence Day and Christmas).ConclusionA wavelet analysis can be used to decompose complex time series. To the best of our knowledge, this is the first application of this technique to the study of suicides in developing countries. This analysis enabled identifying a seasonal pattern among urban men in Mexico. The identification of seasonal patterns can help to create primary prevention strategies, increase the dissemination of crisis intervention strategies and promote mental health. These strategies could be emphasized during specific periods of the year and directed towards profiles with a higher risk.

“…These results are consistent with the findings of Fernández-Niño et al (2016), who found that May was the month with the highest frequency of suicides in Mexico from 2000 to 2013. A recent study analyzed the behavior of suicide in the state of Baja California Sur from 1985 to 2008, observing a sharp increase in suicide rates during the hot season (months with an average temperature of over 30°C), together with an association between temperature and suicide rates (Gaxiola-Robles, Celis de la Rosa, Labrada-Martagón, Díaz-Castro, & Zenteno-Savín, 2013).…”

Introduction. Suicide has shown an international and national trend to increase, mainly in young people, together with seasonal behavior associated with high temperatures. Although Chihuahua saw the highest number of suicides and suicide attempts in 2016, there are no studies documenting their seasonal and trend behavior. Objective. This study sought to analyze the trend and seasonality of completed suicides in the state of Chihuahua from 2008 to 2018. Method. The number of deaths from intentionally self-inflicted injuries was obtained from INEGI. The absolute suicide rate was estimated, and a time series model applied to identify its trend and seasonality. In addition, environmental temperature was used as a predictor variable for the number of suicides through a Poisson model. Results. A trend was found in the completed suicide rate from 2008 to 2018 in men and women, both separately and together (stationary R2 .73, .66 and .69, respectively), together with seasonality in both sexes (p < .002), with the highest figures being recorded in June and July. An increase of 1,028 suicides was found for every 1°C rise in temperature. In the 10-24 and 25-34 age groups, a linear increase in the suicide rate was observed during the period studied (R² > .7, p = .001). Discussion and conclusion. Between 2008 and 2018, the suicide rate increased in the state of Chihuahua, mainly among those aged between 10 and 34. Moreover, suicide rates tend to increase during the months of June and July because of temperature.

“…(15,16,5,7). También, se ha documentado que el incremento de la temperatura ambiental puede ser causal de suicidio (17). Los resultados mostraron que hay una asociación entre las temperaturas ambientales y las afectaciones a la salud, y aunque no se puede demostrar una causalidad con la regresión de Poisson, la literatura indica que hay un efecto de las temperaturas ambientales sobre diversos aspectos de la salud (15,17,14).…”

La alteración de la temperatura ambiental es una de las principales consecuencias del cambio climático, la cual influye en la salud de la población humana, incluso conduciendo a la muerte. El objetivo del presente estudio es analizar los cambios, a lo largo de 14 años, de la temperatura ambiental, máxima, promedio y mínima, en el estado de Hidalgo (México), así como las afectaciones (deshidratación, agotamiento por calor, golpes de calor, quemaduras, intoxicación, e hipotermia) derivadas de ello. Además, se aborda el caso del municipio de Tlahuelilpan. Se consultaron, limpiaron y trataron bases de datos abiertos gubernamentales del estado de Hidalgo, para posteriormente graficarlos y analizar las tendencias. La temperatura ambiental del estado de Hidalgo (máxima, promedio y mínima) mostró un incremento de aproximadamente 2 °C entre 2007 y 2021, registrando temperaturas más altas en los meses marzo – julio, y más bajas en diciembre a enero. Asimismo, conforme avanza el tiempo, se registran los primeros casos de deshidratación, agotamiento por calor y golpes de calor a partir de 2019. Sin embargo, previo a ello, se registraron casos de hipotermia, intoxicación y quemaduras (al encender fogatas en casa) más frecuentemente. Con respecto a las temperaturas ambientales, la hipotermia fue la mayor causa de decesos. En el caso del municipio de Tlahuelilpan, la tendencia de la temperatura ambiental (máxima, promedio y mínima) de 2007 a 2021 fue contraria, con una reducción de aproximadamente 3 °C, lo que sugiere que las afectaciones relacionadas a bajas temperaturas serán la mayor problemática para este municipio.
