Efecto del tiempo de exposición a PM10 en las urgencias por bronquitis aguda

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...
