Efecto a corto plazo de contaminantes atmosféricos sobre la mortalidad en la localidad de Usaquén, Bogota, Colombia entre los años 2009 a 2014

Abstract

Objective: Assess the short-term effect of different air pollutants (PM₁₀, PM₂₅, O₃ and CO) on mortality in age groups of the town of Usaquén among 2009 to 2014 in the city of Bogotá, Colombia. Methodology: The study consisted of time series through statistical adjustments and changes of the type of variable, allowed for Poisson models established relationship between pollutants, the age groups of interest (in all ages, under 14 years old and older 65) and meteorological variables measuring station located in the town (precipitation and temperature). Results: For cardiopulmonary diseases there were three statistically significant cases, the most significant O3 average contaminant appeared in eight hours combined with PM2.5 an increase in mortality of 10.4% (95% CI: 1.7%; 19.7%). In cardiovascular diseases, there were six statistically significant results and the one with the greatest increase in mortality was the maximum hourly CO combined with PM2.5 with 22.6% (95% CI: 1.7%, 47.7%). passing cerebrovascular diseases with four statistically significant results and the most representative of these is when the maximum hourly CO interacts with O3 maximum time with an increase in mortality of 29.5% (95% CI: 2.4%; 63.8 %).

conclusions: It was found that contaminants have greater statistical significance in mortality are ozone in combination with the particulate material affecting all ages and a greater proportion of adults over 65 years, increasing the risk of mortality in cardiovascular disease; other contaminant that has a major impact on health is carbon monoxide interacting with ozone which affect all ages increasing mortality from cerebrovascular disease. Keywords: Mortality, interaction, ozone, carbon monoxide.
