“…Esta adaptabilidad por parte del vector, pone en suspenso la salud pública, esperándose que para el 2050 afecten a grandes poblaciones mundialmente (Dietz, 2020). Por otra parte, el control de roedores como reservorios, también será crítico para la transmisión de enfermedades como la leishmaniasis cutánea, porque con el cambio climático, aumenta el riesgo (Zerbini et al, 2018).…”

El deterioro del medio ambiente ha acelerado el cambio climático (CC) afectando mútiples escenarios, el aumento de la temperatura ha conllevado a la proliferación de diversas enfermedades trasmitidas por vectores de importancia a nivel de salud pública. Como objetivo, se propuso determinar la cultura ecosaludable ante el cambio climático en estudiantes del Área Ciencias de la Educación, Universidad Nacional Experimental Rómulo Gallegos (UNERG), Calabozo, Venezuela 2022. El estudio fue cuantitativo exploratorio no experimental de corte transversal con una muestra de 180 estudiantes. Para la recolección de datos se aplicó el Cuestionario de Dimensiones Ambientales (CDA) compuesto de 75 ítems distribuidos en tres dimensiones; conocimientos, actitudes, emociones y comportamientos. El análisis de los datos fue por estadística descriptiva con porcentajes a través del programa Epidat 3.0. Como resultado, 63% indicó la importancia atribuida de los elementos de ecosalud afectados sobre el agua y 55% al calentamiento global. No obstante, solo 12% indicó la educación como un elemento de ecosalud afectado por el cambio climático, así mismo, en la dimensión de conocimientos se encontró 54,50% a CSN, 6,50% a CPR y 39,50% a CEA, en la dimensión de actitudes y emociones se encontró 55,50% a la subcategoria TD, 44,00% a CVA y 36,50% a E, finalmente, en la dimensión de comportamiento, se evidenció 36,50% a la subategoria de PC, 29,00% a IC y 20,00% a PI. Se debe evitar el daño ambiental a través del cambio de comportamiento individual que debe ser enseñado desde los recintos universitarios.

“…For example, although a handful of studies have used UV exposure as a measure of sunlight exposure, 25,59,60 a more appropriate measure may be sunlight duration. 26,31,61,62 Additionally, the association between UV exposure and suicide may be confounded by meteorological factors, such as seasonality, 62,63 temperature, 24,64,65 or humidity, 61,66 which were not included in our analyses. Furthermore, there is some evidence to suggest that short-term (ie, days) UV exposure is more strongly associ-ated with completed suicide as compared to long-term (ie, months or years) exposure.…”

Purpose To examine the association between contextual factors, represented by geographic and community health variables, and suicide among rural and urban Department of Veterans Affairs health care users (VA users). Methods We performed a retrospective cohort study of 12,700,847 VA users between 2003 and 2017. We assigned contextual factors based on individuals’ home address at the ZIP Code (area deprivation), county (sunlight exposure, altitude, and community health), and state level (firearm ownership), using publicly available data sources. We grouped contextual factors by quintiles or prespecified thresholds, depending on the nature of each variable. We obtained mortality data from the National Death Index. We measured the effect of living in a place with the highest versus lowest level of each contextual factor on odds of suicide using logistic regression, adjusting for individual compositional factors abstracted from VA electronic medical records data. We used random forest modeling to build prediction models for suicide based on contextual factors among rural and urban veterans. Findings Almost all contextual factors we examined were significantly associated with suicide among rural and urban VA users, even after adjusting for individual compositional factors. However, no contextual variables were strong protective or risk factors (0.52.0), and prediction models leveraging these contextual factors had poor accuracy among both rural (0.51, 95% CI: 0.48‐0.54) and urban (0.53, 95% CI: 0.51‐0.55) VA users. Conclusions A wide variety of contextual factors is significantly associated with suicide among rural and urban VA users. However, the factors we measured contributed very little to individual‐level suicide risk.

Findings of the association between hot weather and suicide in a subtropical city such as Hong Kong are inconsistent. This study aimed to revisit the association by identifying meteorological risk factors for older-adult suicides in Hong Kong using a time-series approach. A retrospective study was conducted on older-adult (aged ≥65) suicide deaths in Hong Kong from 1976 to 2014. Suicides were classified into those involving violent methods and those involving nonviolent methods. Meteorological data, including ambient temperature, were retrieved. Transfer function time-series models were fitted. In total, 7314 older-adult suicide deaths involving violent methods and 630 involving nonviolent methods were recorded. For violent-method suicides, a monthly average daily minimum ambient temperature was determined to best predict the monthly rate, and a daily maximum ambient temperature of 30.3 °C was considered the threshold. For suicide deaths involving nonviolent methods, the number of days in a month for which the daily maximum ambient temperature exceeded 32.7 °C could best predict the monthly rate. Higher ambient temperature was associated with more older-adult suicide deaths, both from violent and nonviolent methods. Weather-focused preventive measures for older-adult suicides are necessary, such as the provision of more public air-conditioned areas where older adults can shelter from extreme hot weather.
