RESUMEN
Resumen Objetivo:
Estimar el riesgo de mortalidad asociado con la exposición a partículas finas (PM2.5) y gruesas (PM2.5-10) en la Zona Metropolitana de Monterrey (ZMM). Material ymétodos:
Estudio ecológico con análisis retrospectivo de series de tiempo (2004-2014) de mortalidad total y específica diaria, y promedio de PM2.5y PM2.5-10. Modelos aditivos generalizados Poisson con rezagos distribuidos ajustados por tendencia, estacionalidad, día de la semana, condiciones meteorológicas y contaminantes gaseosos.Resultados:
El promedio (DE) de PM2.5y PM2.5-10fue 26.59 (11.06) y 48.83 (21.15) μg/m3. Cada 10 μg/m3de aumento de PM2.5(lag 0) incrementó el riesgo de mortalidad respiratoria en menores de cinco años 11.16٪ (IC95% 1.03-21.39) y de neumonía e influenza en mayores de cinco años 11.16٪ (IC95% 3.91-9.37). El riesgo de mortalidad asociado con las PM2.5-10fue menor.Conclusiones:
Se observaron asociaciones positivas y significativas entre exposición a material particulado y la mortalidad diaria en población de la ZMM.ABSTRACT
Abstract Objective:
To estimate the mortality risk of fine (PM2.5) and coarse (PM2.5-10) particles in the Metropolitan Area of Monterrey (MAM). Materials andmethods:
A retrospective ecological time-series analysis (2000-2014) was conducted using total and specific causes of mortality, and daily mean PM2.5and PM2.5-10. Generalized additive distributed lag models controlling for trend, seasonality, day of the week, meteorological conditions and gaseous pollutants.Results:
Mean (SD) PM2.5and PM2.5-10concentrations were 26.59 μg/m3 (11.06 μg/m3) and 48.83 μg/m3(21.15 μg/m3). An increase of 10 μg/m3 of PM2.5 (lag 0) was associated with 11.16% (95%CI1.03-21.39) increased risk of respiratory mortality in children <=5 years old and 6.6% (95%CI 3.31-9.37) increased risk of pneumonia-influenza in adults >=65 years old. The risk of mortality associated with the concentration of coarse particles was lower.Conclusions:
Positive and significant associations were observed between exposure to particulate matter and daily mortality in the MAM´s population.Key words
