Abstract

Abstract: The aim of the present study is to analyse the age effect on the lag patterns of relative risk of hospitalization for acute myocardial infarction and NO2, PM10 and O3 . Daily hospitalizations for AMI during the period 2008–2011 were extracted from administrative data. Analyses were performed using the quasi-Poisson regression model adjusted for seasonality, long-term trend, day of the week and temperature. We observed very different patterns depending on age. For NO2 and PM10, the younger group (25–54 years) shows a more delayed effect in comparison with the two older age groups (55–64 and ≥ 65 years). Overall, the associations between NO2 and AMI are higher compared to PM10 . There are no associations between O3 and AMI. This study indicates that age plays a major role in the lag pattern. Younger people have delayed effects, but they are nevertheless sensitive to air pollution.
