We quantify the short-term effects of noise levels on daily mortality due to respiratory diseases.Methods: A time-stratified case-crossover design was used. Daily mortality counts in Madrid city due to all respiratory diseases (ICD10: J00-J99), respiratory failure (ICD10: J12-18), chronic diseases (ICD-10: J40-J44), asthma (ICD-10: J45-J46) and pneumonia (ICD10: J96) from 2003 to 2005 were collected. Noise levels were collected as 24h-average daily equivalent noise (Leq24h). Over-dispersed Poisson regression models were adjusted to control for time trend and seasonality, weather variables and primary chemical air pollutants (PM2.5 and NO2).Results: For an increase of 0.5 db(A) of Leq24h the percentage risk of mortality rise, at 1 day lag, 3.5% for all respiratory diseases and 8% for pneumonia, while for chronic diseases the risk rise 6% at 4-days lag. No effects were found for asthma. Estimates did not change after adjusting for PM2.5 and NO2.Conclusions: The association found between noise exposure levels and respiratory mortality suggests independent effects of noise exposure levels and air pollutants. This puts forward the need to seriously consider the high noise exposure levels reported as an important public health issue. ER -
