Investigators want to learn the role of indoor environmental exposures on respiratory symptoms, and, separately, on lung function deficits in school-aged children with bronchopulmonary dysplasia (BPD).
Bronchopulmonary Dysplasia, Chronic Lung Disease of Newborn, Environmental Exposure
Bronchopulmonary dysplasia (BPD) is the most common respiratory disease affecting children born prematurely and leads to long-term respiratory symptoms and lung function impairment throughout childhood. This study will, evaluate the contribution of indoor sources of respiratory irritants to respiratory health impairment in school-aged children with BPD. State-of-the-art measures of indoor air quality constituents will assess the relationship of nitrogen dioxide (NO2), particulate matter (PM2.5), as well as, concentrations of allergens (mold, mouse, cockroach, pet), endotoxin, air temperature and humidity with concurrently measured respiratory symptoms and lung function in a well-characterized cohort of children with BPD. This research will identify specific harmful components of the indoor environment associated with respiratory morbidity and poor lung function in children with BPD. Investigators will ask the participants to come in for a one time clinic visit for undergoing procedures as well as answering questions regarding health and home environment. During the 1 year of participation there will also be 2 home assessment visits where investigators will take a sample of the home environment as well record home characteristics.
