Research Points to Location of Mold and Heightened Asthma Risk

A February, 2015, study published in Pediatrics notes that while “excess moisture and visible mold are associated with increased risk of asthma [few] studies have performed detailed home visits to characterize the extent and location of moisture damage and mold growth. Structured home inspections were performed in a birth cohort study when the children were 5 months old (on average). Three hundred and ninety eight children “were followed up to the age of 6 years.”

The authors report that “moisture damage and mold at an early age in the child’s main living areas (but not in bathrooms or other interior spaces) were associated with the risk of developing physician-diagnosed asthma ever, persistent asthma, and respiratory symptoms during the first 6 years. Associations with asthma ever were strongest for moisture damage with visible mold in the child’s bedroom and in the living room. Associations with asthma ever were stronger in the earlier part of the follow-up and among atopic [allergy-related] children. No consistent associations were found between moisture damage with or without visible mold and atopic sensitization.”

The researchers conclude that “moisture damage and mold in early infancy in the child’s main living areas were associated with asthma development. Atopic children may be more susceptible to the effects of moisture damage and mold.”
