  1. Indoor airborne fungal spores, house dampness and associations with environmental factors and respiratory health in children.

    Article - En anglais

    Background Children living in a damp house are more likely to suffer from respiratory symptoms and it has been suggested that exposure to fungi is an important contributing factor.

    However, more knowledge about underlying mechanisms for the association are needed.

    Objective To identify associations between measures of house dampness, levels of airborne fungal spores, housing factors and health outcomes in children.

    Methods Eighty households with 148 children between 7 and 14years of age were recruited in the Latrobe Valley, Victoria, Australia.

    Some 36% of participating children were asthmatic.

    Six sampling visits were made to each house between March 1994 and February 1995 on a 2-monthly cycle.

    Samples for airborne total and viable fungal spores were collected from bedrooms, living rooms, kitchens and outdoors.

    A detailed dwelling characterization, using a questionnaire and inspection surveys, was carried out.

    Skin-prick tests were performed with extracts of common aeroallergens and a respiratory questionnaire was completed for each child.

    Results Large airborne fungal spore concentrations were recorded in association with : musty odour, water intrusion, high indoor humidity, limited ventilation through open windows, few extractor fans and failure to remove indoor mould growth.

    Visible mould growth or condensation evidence was associated with large concentrations of Cladosporium spores, but not with large total spore concentrations. (...)
