Resumo: | To study the health effect of air pollution, measured as particulate matter greater than 10mm in diameter (PM10), we analyzed the effect of daily hours of exposure on the number of urgency admissions for acute bronchitis, adjusting for temperature and humidity on the same day. The study was conducted in six regions of Santiago, Chile, during the winter of years 2002 to 2004, for infants and elders. The delay between pollution time series and disease was modeled using a polynomial distributed lag (PDL) function included in a generalized linear model. The linearity assumption was evaluated using a smooth-spline model approach. The highest effect for exposure to PM10 was detected with 4 days of delay. For both groups, the effect of temperature was linear, but that of humidity was not. Air pollution effect varied according to level of exposure and geographic region, increasing by 3% the total number of infant emergency consultations for each hour of exposure to levels greater than 150µg/m³. The study thus showed a significant impact of air pollution on population health. |

El estudio fue realizado en seis sectores de la ciudad de Santiago, Chile, durante el período de invierno de los años 2002 al 2004, para lactantes (< 1 año) y adultos mayores (> 65 años). Analizamos el retraso de la respuesta mediante una función polinomial distributiva (pdl), incluida en un modelo lineal generalizado (GLM-pdl), y la estructura del efecto de la exposición, mediante modelos aditivos generalizados (GAM), utilizando regresión spline como técnica de estimación. Los resultados mostraron que al cuarto día de retardo, el efecto de la exposición fue mayor, especialmente en lactantes, y varió en la medida que incrementó la concentración atmosférica de PM10. El efecto de las horas de exposición a PM10 mostró una variación significativa, según el sector geográfico. Al estimar linealmente este efecto en el sector Oeste, notamos que el incremento de consultas diarias en lactantes fue de 3% por cada hora de exposición sobre os 150µg/m³.Reports in Public HealthCadernos de Saúde Pública2009-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/4120Reports in Public Health; Vol. 25 No. 3 (2009): MarchCadernos de Saúde Pública; v. 25 n. 3 (2009): Março1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZspahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/4120/8377https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/4120/8378Muñoz, FranzCarvalho, Marilia Sáinfo:eu-repo/semantics/openAccess2024-03-06T15:28:00Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/4120Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:04:45.757794Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
