A multicentre study (Pollution Effects on Asthmatic Children in Europe (PEACE)) project investigated the relationship between the air pollution and daily variation of respiratory health in children with chronic respiratory symptoms. Data were collected on 66 children in Prague and 68 children in Benesov, Czech Republic. The panels were followed from January 17 to April 12, 1994. Respiratory symptoms and peak expiratory flow were recorded on a daily basis in a diary. Ambient air pollutants as well as meteorological parameters were measured at local monitoring stations on a daily basis. Mean particles with a 50% cut-off aerodynamic diameter of 10 μm (PM10) (SO2) levels were 53 (114) μg.m-3 and 50 (31) μg.m-3 in Prague and Benesov, respectively. The association between air pollution and health outcomes was analysed using time series regression models. Between air pollution and symptom prevalence a small association was found, also between air pollution and prevalence of medication use. No association of air pollution and peak flow or between air pollution and respiratory symptom incidence indicating an adverse effect could be detected. In conclusion, a small effect of air pollution on the prevalence of respiratory symptoms and medication use was detected.
