Análise do padrão de associação entre internações por doenças cardiovasculares e temperatura do ar. Estudo de casos: região Centro-Oeste do Brasil

Abstract

This research was motivated by a journalistic article that linked extreme temperatures to heart diseases. The main objective was to investigate the influence of temperatures in the cities of Brasília, Cuiabá, and Goiânia on the number of hospital admissions due to cardiovascular diseases. Data from maximum and minimum average temperatures were obtained from the Meteorological Database (BDMEP), while data on hospital admissions for heart diseases were obtained from the Hospital Information System of the Unified Health System (DATASUS). The analyzed period was from January 2010 to December 2022. The methodology involved an exploratory data analysis, correlation tests, data categorization, and chi-square test. The statistical analysis did not provide evidence of a direct association between air temperature and the incidence of cardiovascular diseases in the studied cities. The exploratory analysis, data categorization, and correlation test did not reveal a consistent pattern between the variables. Based on the results, it can be concluded that there is no statistically significant relationship between temperatures and the number of hospital admissions for heart diseases in the cities.
