== Scope ==



Exposure-response function for short-term (acute) exposure to ambient air particulate matter (PM) with an aerodynamic diameter < 10 µm and medication (bronchodilator) usage by people with asthma. 

'''Dimensions and boundaries relevant for the variable

*RR of 1.005 (95% Cl 0.981, 1.029) for bronchodilator usage by children with asthma (meeting PEACE study criteria) per 10 µg/m<sup>3</sup> PM<sub>10</sub>
*RR of 1.010 (95% Cl 0.990, 1.031) for bronchodilator usage by adults with asthma (well-established) per 10 µg/m<sup>3</sup> PM<sub>10</sub>

Note! the associations are not statistically significant at the usual 5% level.

*Annual change of 180 (95% Cl -690, 1060) days in brochodilator usage per 10 µg/m<sup>3</sup> PM<sub>10</sub> per 1000 children aged 5-14 years with asthma (meeting PEACE study criteria)
**Based on the RR by WHO task group (2004) and 10% background prevalence of daily bronchodilator use
*Annual change of 912 (95% Cl -912, 2774) days in brochodilator usage per 10 µg/m<sup>3</sup> PM<sub>10</sub> per 1000 adults aged 20+ with well-established asthma with asthma (well-established)
**Based on the RR by WHO task group (2004) and 50% background prevalence of daily bronchodilator use
**4.5% of European adult population was estimated to have well-established asthma

=== Causality ===


=== Unit ===



Annual change in no. of days of bronchodilator usage per 10 µg/m3 increase in exposure per 1000 persons

=== Formula ===
