RESUMO
The aim of this study was to identify the correlation between the number of deaths of elderly people and climate change in the district of São Carlos (SP) over a period of 10 years (1997-2006). Records of deaths were obtained from DATASUS for people aged over 60 who died between 1997 and 2006 in São Carlos. The average monthly maximum and minimum temperature data and relative air humidity in São Carlos were provided by the National Institute of Meteorology. The mortality coefficient of the district was calculated by gender and age and the resulting data were analyzed using t test, one-way ANOVA, the Bonferroni test and the Pearson correlation coefficient test. There were 8,304 deaths which predominantly occurred among males aged over 80, and diseases of the circulatory system were the main cause of death. There was a positive correlation between mortality by infectious disease and minimum humidity, and a negative correlation between mortality by infectious diseases and minimum temperatures, between mortality caused by respiratory disease and minimum humidity, between mortality caused by endocrine disease and minimum and maximum temperature. Thereby, it was possible to conclude that there was a correlation between climate change and mortality among elderly individuals in São Carlos.

O objetivo desse estudo foi identificar as correlações existentes entre o número de óbitos de indivíduos idosos e as alterações climáticas no município de São Carlos (SP) em um período de 10 anos (1997-2006). Foram colhidas informações do registro de óbitos por meio do DATASUS, de pessoas com 60 anos ou mais, falecidas entre 1997 e 2006 no município. Os dados mensais da média das Temperaturas Máxima, Média e Mínima e da Umidade Relativa do Ar no município de São Carlos foram fornecidos pelo Instituto Nacional de Meteorologia. Calcularam-se os coeficientes de mortalidade do município, por sexo e faixa etária e os dados foram analisados com teste t, ANOVA de fator único, teste de Bonferroni e teste de Pearson. Ocorreram 8.304 óbitos, com predominância de indivíduos na faixa dos 80 anos ou mais, do sexo masculino. As doenças do aparelho circulatório foram as principais causas de óbito. Houve correlação positiva entre mortalidade por doenças infecciosas e Umidade Mínima e correlação negativa entre mortalidade por doenças infecciosas e Temperatura Mínima Mínima, entre mortalidade por doenças respiratórias e Umidade Mínima, entre mortalidade por doenças endócrinas e Temperatura Mínima Mínima e Temperatura Máxima Máxima. Dessa forma, foi possível concluir que houve relação entre o clima e a mortalidade de idosos em São Carlos.
