Influência e correlação de variáveis meteorológicas com infarto agudo do miocárdio e diabetes mellitus.

Abstract

The changes in the cities urbanization process and the changes that occur with meteorological variables over a region contribute to higher incidence of morbidity. This work aimed to study the influence of meteorological elements and its correlation in cases of acute myocardial infarction and diabetes mellitus in Campina Grande-PB in the years 2000 to 2009, in order to understand the normal behavior and improve control of these diseases, by the monthly averages of atmospheric pressure, mean temperature, maximum and minimum temperatures of air, temperature range, relative humidity, rainfall, wind speed, solar radiation and evaporation. Using weather data collected at the main meteorological station of the National Institute of Meteorology located at the Brazilian Enterprise for Agricultural Research in Campina Grande (07 º 13 'South, 35 ° 53' W). Altitude 543 m and information about morbidity provided by the Municipal Health Department of Campina Grande-PB city, this study presents correlations involving these variables. Possible relationships between the dependent and independent variables, showing the influence of climate on the morbidities studied were demonstrated in this study using Principal Component Analysis. It was found that the weather elements directly influence the incidence of acute myocardial infarction and diabetes mellitus and the factors that contributed most to the increase in the number of cases of acute myocardial infarction are the maximum air temperature and wind speed. The cases of diabetes mellitus had better correlation with rainfall and sunshine, however, the maximum and minimum temperatures of air were also largely responsible for these incidents. It was also noticed that sunlight was the main weather element in the incidence of morbidities studied.
