The objectives of this thesis were: (i) assess the role of indoor air pollutants and allergens with respect to their individual contribution to EIB and reported asthma in elementary schoolchildren in Montreal and Port Alberni; and (ii) to determine how the effect of these indoor environmental pollutants and allergens are modified by host factors, such as gender. The hypothesis was that increased levels of indoor allergens and pollutants are associated with a higher prevalence of asthma and/or EIB; this association being modified by gender. / Initially a cross-sectional study was carried out of 989 Montreal elementary schoolchildren, and 1,785 Port Alberni elementary schoolchildren. A questionnaire was completed by the parents and exercise test was carried out in which the children performed spirometry before and after a free running exercise test. / For the purpose of this thesis a sub-sample of 332 children from Montreal and 305 children from Port Alberni were combined and a more detailed case-control study pertaining to home environment carried out.
