- W2263305711 abstract "Background: It has been suggested an effect of air pollution in the exacerbation of respiratory symptoms during acute airway infections in children. Our objective was to explore this association. Methods: We included patients under 16 years old with lower respiratory tract infection in the Emergency Room of the Hospital Espanol. We evaluated their respiratory impairment. Air pollution measures were obtained, the Air Quality Metropolitan Index (IMECA) and ozone highest concentrations and means; in the zone were the child had been for the last 48 hours. Results: 38 patients were evaluated. 84% (33/38) of them were exposed at high ozone concentration, 73.7% of children were exposed to IMECA between 50-100 points. Fifty five percent (21/38) were classified as high risk. We found a tendency between ozone and IMECA concentrations and respiratory severity [Odd Ratio = 1.2 (CI95% 0.14 to 10.1) for ozone concentration of 0.04-0.08, and 7.6 (CI95% 0.74 to 86.5) for > 0.08, c2tend p = 0.05; and for IMECA OR = 4.05 (CI95% 0.71 to 22.9) for 50-100 points, and 14.6 (CI95% 0.5 to 387) for > 100 pts, c2tend p = 0.07]. Conclusions: Even though we found that ozone concentration affects respiratory failure, we did not demonstrate a statistical significance association, because of the high prevalence of air pollution in Mexico City." @default.
