A case-base study of residential IEQ related risk factors and parental reports of asthma and allergy among 500 Danish children - IECH

Five-hundred Danish families with children aged 3 to 5 years were included in a study of the indoor environments in their dwellings and their children's kindergartens, the aim being to assess the influence of the exposures that occur in both these environments on the children's health. Exposures were evaluated based on parents' reports of dwelling characteristics and inspectors' reports derived from visits to the dwellings. Parents' reports of moisture problems seemed to be associated with cases (asthma, rhinitis, and eczema) more than bases, whereas there was no statistically significant association between inspector observations of moisture, odor, or mould and three health symptoms (wheezing, rhinitis, and eczema).
