Canadian Healthy Infant Longitudinal Development (CHILD) Study: Indoor markers of moisture in a prospective birth cohort

摘要

Excessive indoor moisture has been linked to adverse respiratory outcomes, and is known to promote the growth of harmful microorganisms. Using the Canadian Healthy Infant Longitudinal Development (CHILD) Study's home environment dataset (Takaro et al, 2015), we explored the relationship between the presence of window condensation and mould, leaks, and plants. Mould and leaks were associated with increased window condensation (OR=3.39, OR=1.25), whereas plants had no effect when we controlled for season, study centre, humidification, and frequency of window openings. Subsequent analyses of the CHILD dataset will explore time-activity behaviours in relation to moisture, and the presence of plant-related fungal species in dust samples.
