Asthma severity
Brief Description:
The STAR study examined the role of exposures to indoor allergens and indoor and outdoor nitrogen dioxide (NO2) on the severity of asthma. The study enrolled approximately 1,400 asthmatic children ages 5-11 years old from urban and suburban Connecticut and Massachusetts between 2006 and 2009. This study led to an intervention trial to test the efficacy of indoor air cleaners in reducing NO2 exposure and improving health in asthmatic children.
