Abstract

Abstract: Objectives: The 'Mon habitat: plus qu'un simple toit' (MHPQST) survey was designed to identify public health risks and priorities for local decision makers in relation to housing. The aims of the present study were to describe the exposure of households to indoor air contaminants and to verify the relationship between these contaminants and respiratory symptoms/diseases. Study design: This is a cross-sectional study. Methods: MHPQST was conducted in Baie-Saint-Paul, a French Canadian municipality (7000 inhabitants) using a protocol adapted from the 'Large Analysis and Review of European Housing and Health Status' study performed in Europe in 2002–2003. Households were selected from two sectors (less favorable and more favorable). Data collection was achieved using three tools (two questionnaires and one inspection grid). Indoor air variables were analyzed in relation to respiratory symptoms/diseases using logistic regression models adjusted for age, gender, income, smoking status, and proximity. Results: A total of 161 dwellings (294 inhabitants) participated in the survey. Presence of mold on walls, ceilings, or floors was detected by the investigators in 21% of the dwellings. Nearly half of the households were in contact with a pet at home and 12% with environmental tobacco smoke. Exposure to these three determinants was significantly associated with certain respiratory symptoms/diseases. Conclusion: Molds, pets at home, and environmental tobacco smoke are environmental determinants that were associated with respiratory health in the present survey. These results enabled sensitizing local stakeholders regarding the importance of indoor air quality for the respiratory health of their population. Highlights: Molds, pets, and environmental tobacco smoke were associated with respiratory health. Indoor air quality is an important determinant of respiratory health. Local survey is an interesting tool to sensitize authorities to health priorities.
