Evaluación de los efectos a corto plazo de los contaminantes criterio del aire sobre la mortalidad cardiopulmonar en el periodo 2001-2007 en la ciudad de Bucaramanga (Santander).

Abstract

An ecological study of time series was carried out with the objective of assessing whether there are short-term effects of air pollutants on cardiopulmonary mortality in the city of Bucaramanga (Santander), the mixed poisson regression was applied through the STATA software 11.0, using as base information the data collected from the 5 monitoring stations belonging to the City's Air Quality Monitoring System, this in the case of criteria pollutants and meteorological variables; Mortality data were provided by the Secretary of Health of Bucaramanga, the period studied was 2001-2007, descriptive statistics were applied for the two bases, obtaining data such as mean, standard deviation, máximum, mínimum, percentiles (25 and 75). The Relative Risk was found from the software for each of the pollutants and their different mixtures relating them to the different diseases and their age groups, in addition to the immediate effects and their deferred days (1-5). From the above, it was obtained that none of the diseases had a statistical relationship with the mixtures of the contaminants, but if there is an individual relationship, to a greater extent with carbon monoxide (CO), it was also observed that for cardiopulmonary mortality with a day of delay (Lag 1) a change in the risk of 4,34% was observed and by a 5 ppb increase in the average 24 hours of NO2 in the group of those over 65 years of age a risk of 2,55% was evidenced. The study from the results allows us to conclude that if there is an association of air pollutants individually as determinants of cardiopulmonary health of Bucaramanga
