“…High population density regions have more human activity such as vehicle and air-conditioning use that contributes to the local heat island (Luber and McGeehin 2008;Smith et al 2009). (2) Elderly people have lower adaptation ability and higher mortality rates (Poumadère et al 2005;Vescovi et al 2005;CDC 2002;Pan et al 1995). Older people have decreasing regulatory abilities for intrinsic homeostasis, making them insensitive to temperature changes and unaware of becoming ill (Koppe et al 2004).…”

Motivated by growing heat-related morbidity and mortality in a warming climate, this paper assesses global heat health risk in order to understand the challenges to sustainability in the 21st century, using four Representative Concentration Pathways (RCPs) of the HadGEM2-ES climate model and five Shared Socio-Economic Pathways (SSPs). Factors influencing global heat health risk were reviewed and risks were estimated based on heat hazard and socio-economic vulnerability. Hazard, vulnerability, risk and in particular, populations at different risk levels, were analyzed quantitatively at both global and regional scales. The results show that under an RCP8.5-SSP3 scenario, the world will be subject to the highest heat health risk, with rapidly increasing hazard levels and vulnerability over the century. Less developed or developing regions, such as Africa and Southeast Asia, are at the highest risk. The heat risk under an RCP2.6-SSP1 scenario will first increase and then fall, resulting in the lowest heat-health-risk pattern. We found that heat health risk will increase during the century under all RCP-SSP scenarios, with a higher frequency, higher intensity, longer duration and Climatic Change (2015) expanding spatial reach. Significant differences were observed across regions. The results make clear that the increasing risk poses significant challenges to sustainable human health. To meet these challenges, more attention and effective actions are urgently needed from both policy makers and individuals.

“…Essa relação tempo-morbidade é evidente, devido à falha do mecanismo de defesa homeostático com o avanço da idade, que por sua vez provocaria dificuldades respiratórias ou outras doenças (20) . A DAR está entre as principais causas de consulta médica, sendo responsável por mais de um terço delas e por um grande número de hospitalizações em crianças e adultos, na maioria dos países (21) . A faixa etária com maior incidência de DAR ocorre entre seis meses e quatros anos e maiores que 60 anos de idade, tanto em países desenvolvidos quanto naqueles em desenvolvimento.…”

“…A diferença da morbidade da DAR entre os países mais ricos e os em desenvolvimento é que nestes são mais frequentes os casos mais graves, particularmente as pneumonias, as quais muitas vezes vêm com complicações fatais. É fato descrito que a taxa de mortalidade da DAR é maior nos países com menor qualidade de vida dos seus habitantes (21) . Outro indicador de gravidade da DAR é a taxa de hospitalização em determinado serviço.…”

RESUMOObjetivo: Avaliar a relação entre variáveis meteorológicas e doenças respiratórias por faixa etária. Métodos: Trata-se de um estudo ecológico de séries temporais para o período compreendido entre 2008 e 2011. Primeiramente, as internações foram analisadas por grupo de faixa etária e, em seguida, relacionadas com informações climáticas, temperatura, precipitação, umidade relativa do ar e velocidade dos ventos, através da climatologia dinâmica e de parâmetros estatísticos, utilizando análise de regressão múltipla, teste qui-quadrado e distribuição normal. Resultados: Os resultados mostraram 12.067 registros de internações por doenças respiratórias e por faixa etária. As maiores médias de internação ocorreram na faixa etária de 1 a 4 anos, com média de 42,09%, (5.079) e acima de 60 anos, com média de 27,14% (3.274) para o período de estudo, sendo as pneumonias predominantes, com 81,0% (9.774) das internações. Verificou-se menor número de internações em janeiro e maior, em junho e julho. Conclusão: Com base nas investigações realizadas, observou-se correlação significativa entre os parâmetros climáticos e as internações por doenças respiratórias. Descritores

“…Thermal stress, due to very low as well as very high temperatures, can trigger alterations in physiological processes, and maybe physiopathological ones, determining a seasonal variation in cardiovascular events [12][13][14][15] . Some observational studies have shown that the correlation between temperature and cardiovascular events, including ventricular arrhythmias, can be expressed by a U-shaped curve, with an increase of events at the highest as well as the lowest temperature extremes [16][17][18] . In the city of Sao Paulo, Sharovsky et al…”

“…The possible reason for this finding is that the study included more females than males, as previous studies did not demonstrate the influence of gender on the seasonal variation of cardiovascular events 20,21 . Age, however, has an effect on the seasonal variation of sudden death and myocardial infarction 3,17 . In this study, no effect of age on the seasonal variation of VT was observed.…”

objective: To evaluate the seasonal variation of ventricular arrhythmias and its correlation with ambient temperature in patients submitted to 24-hour Holter monitoring in the city of Porto Alegre, southern Brazil. Methods:Holter monitoring reports of 3,034 patients from 1996 to 2002 were analyzed. Ventricular tachycardia (VT) was defined as the presence of 3 or more consecutive ventricular beats, at a rate equal to or higher than 100 beats per minute.Percentage distribution of patients presenting VT by seasons and its correlation with ambient temperature were analyzed. results: Mean age was 59.2 ± 17.4 years, with a predominance of the female sex (61.9%). Patient distribution by season of the year was: 561 (18.5%) in summer, 756 (24.9%) in fall, 843 (27.8%) in winter and 874 (28.8%) in spring. Fifty-two patients (9.3%) presented VT episodes in summer, 39 (5.2%) in autumn, 56 (6.6%) in winter and 60 (6.9%) in spring (p = 0.035). There was a 40% relative increase in the proportion of patients presenting VT during summer in comparison to winter. There was a trend of increase in the proportion of patients presenting VT with rising temperatures (r = 0.57; p = 0.052). conclusion:The occurrence of VT presents seasonal variations in southern Brazil, with a higher proportion of episodes occurring in summer. There is an association trend between VT and temperature increase. In the last years, several studies have demonstrated a seasonal variation in the incidence of cardiovascular events, such as myocardial infarction, sudden death, ventricular arrhythmias and stroke [1][2][3][4]
