Abstract

With the epidemiological transition in Brazil, chronic diseases are now responsible for more deaths among men and women. Among the components that define the state of human health, some geographical context, as local climate and socioeconomic factors appear to influence the mortality from circulatory diseases, such as in stroke and pulmonary embolism (PE). The main objective of this study was to investigate the influence of the geographical context (meteorological variables, climate index and socioeconomic factors) in mortality from cardiovascular diseases (stroke and PE) in São Paulo, between 2002 to 2011. In order to analyze the association of mortality with the meteorological variables we used a generalized linear model using the Poisson distribution and distributed lag non linear models. Spatially the association of mortality with socioeconomic variables were tested using the spatial regression models OLS and GWR. As a result we found that both the cold and the heat are risk factors for all types of stroke and PE with a higher risk depending on the type of men and women. Spatially the highest values of relative risk (RR) for stroke mortality were concentrated in the outskirts of the city of São Paulo, which coincided with areas of lower per capita income and vegetation and higher percentage of black population. In relation to spatial distribution of high values of RR PE by these were present mainly in the inner area. In conclusion, our research has generated a lot of results that show that both environmental and socioeconomic variables influence on mortality from some diseases of the circulatory system. In view of the urgent care for stroke and PE cases can avoid serious sequelae and deaths, a better understanding of the importance of geographic context may allow the development of warning systems at the urgent care services and targeting campaigns for the prevention of avoidable risk factors.
