Relação entre poluição do ar e internações de adultos por doenças cardiovasculares totais em São Paulo entre 2000 e 2013

Abstract

This observational, ecological time series study aims to verify the relationship between adult hospitalizations for total cardiovascular diseases (CVDD) and air pollution stratified by sex in residents of the city of São Paulo from 2000 to 2013, observing their Structure of lag. Analyzes were stratified by age group and sex and included hospitalizations for Total Cardiovascular Diseases (ICD10: Chapter IX - I00-I99). The pollutant and meteorological data were provided by the Environmental Sanitation Technology Company of the State of São Paulo. The relationship between air pollutants and climatic factors in hospitalizations for Total Cardiovascular Diseases was analyzed by means of a polynomial distribution lag model for both temperature and air pollutants with a lag structure of up to 6 days after exhibition. Generalized linear models of Poisson regression were used, controlling for long-term seasonality, days of the week, and holidays. The following was calculated the increase in the number of hospitalizations for the interquartile difference of the pollutants significant in the regression model, as well as for the meteorological factors. For all hospital admissions for Total Cardiovascular Diseases, acute short-term effects were observed. The O3 was the only pollutant that did not have any relation to any of the analyzed results and NO2 had the greater effect, for an increase of interquartile 50.22 ¿g / m 3 of NO2, an increase of 13.09% (IC95 %: 4.74% - 21.45%), among the total admissions from 30 to 44 years. Stratifying the analysis by age group, a greater effect was found for hospitalizations from 45 to 60 years. Regarding gender, between the age group 30 and 44, the men stood out, and for the 45-60 age group, the women were more affected than the men.
