Time Series Study of Air Pollution Health Effects in COPSAC Children

30-06-2005

The aim of the study was to examine the association between daily ambient air levels of air pollution in the Copenhagen area and daily airway symptoms among small children. 411 children all of which were inheritable predisposed for development of asthma or other allergic diseases were followed from birth to the age of 18 months. In the study it was found that high pollution levels measured at measurement stations along busy roads (H.C Andersens Boulevard and Jagtvej) were associated with an increase in wheezing symptoms the following days among children living in the central Copenhagen. Among children living outside the centre in the suburbs and further away a much weaker association was found between air pollution levels and airway symptoms. The increase in symptoms was especially associated to carbon monoxide and nitrogen oxides, which predominantly are traffic-derived pollutants. Associations to particle levels were also found.
