The indoor environment and childhood allergic diseases : the importance of allergens and microbial components
Appears in the following Collection
AbstractIndoor environmental agents are believed to contribute to allergic disease development. Based upon the prospective cohort "The Environment and Childhood Asthma Study", this thesis explores associations between allergens and microbial substances in the homes and the development of allergic disease in children. Increased levels of cat allergen at 2 years were found to be associated with increased risk of asthma, but not allergic sensitization, at 10 years. On the other hand, the levels of dog allergen, endotoxin (bacteria), and ß(1,3)-glucans (moulds) showed no association with allergic disease. At the age of 10 years, girls had higher levels of cat and dog allergens in mattress dust compared to boys, which could not be explained by more pet keeping. House dust mite allergens were only detected in 12% of the samples, and were associated with symptoms of rhinitis in girls only. Families of children with rhinitis more often avoided pets whereas asthma did not reduce the likelihood of having a pet at home. Factors like parental smoking, single parenthood and having daughters were also found to be important for the families’ choice in regard to pet keeping.
