Project Title:School Inner-City Asthma Intervention Study
Project Summary:SICAS 1: Allergic asthma is the most common chronic disease of childhood in the United States. Asthma is also the number one cause of school absences in America. The role of indoor allergen exposure in homes and asthma development and morbidity has been extensively studied. Because children spend a significant amount of time in school, the school classroom environment may be as significant a source of allergen exposure and consequent asthma morbidity as allergen exposure in the home. However, little is known about the role of allergen exposure in schools and asthma morbidity. We hypothesize that exposure to common indoor allergens in the classroom will increase the risk of asthma morbidity in inner-city children with asthma, even after controlling for home allergen exposures. In a longitudinal study of 300 elementary school-aged children with asthma from multiple classrooms in close to 40 inner-city schools, we will examine the following specific aims: 1) to test whether elevated levels of allergens in the classroom increase the risk of asthma morbidity, even after controlling for allergen exposure in the home; and 2) to test whether the risk of increased asthma morbidity in relation to elevated classroom levels of a specific allergen will be highest for those specifically sensitized to that allergen. An understanding of exposure risk factors specific to the school classroom is critical, because the school classroom environment could potentially be considered as an effective target for prevention of inner-city asthma morbidity by reducing exposures to many symptomatic children through school- based interventions. While the potential importance of the classroom environment to the health of asthmatic children has been recognized nationally, study of this area has lacking. This unique application will build on significant collaborations between the Channing Laboratory at the Brigham and Women's Hospital, Children's Hospital Boston, the Harvard School of Public Health, the University of Massachusetts Amherst, and the Boston Public School System. Our multidisciplinary research group has significant expertise in asthma epidemiology and environmental epidemiology (Drs. Phipatanakul and Gold), environmental assessment (Drs. Phipatanakul, Gold, Muilenberg, and Rogers), and statistics (Drs. Ryan, Hoffman, and Subramanian). In addition to its public health relevance, this proposal will recruit a unique school pediatric cohort that will facilitate future hypothesis testing. PUBLIC HEALTH RELEVANCE: Asthma is a disease that affects more than 12% of Americans under the age of 18 for over 14 million missed school days per year, and is the number one cause of school absences in America. Elementary school children spend 6 to 10 hours a day in school, and most of that time is spent in one classroom. The goals of this project are to provide an understanding of exposure risk factors specific to the classroom. This is critical, because the classroom environment could potentially be considered as an effective target for prevention of inner-city asthma morbidity by reducing exposures to many symptomatic children through an intervention in the school classrooms.; SICAS 2: Asthma is the most common chronic disease of childhood in the United States, causes significant morbidity, particularly in the inner-city, and accounts for billions of dollars in health care utilization, despite aggressive measures to identify remediable causes. Home environments are established sources of exposure that exacerbate symptoms and home-based interventions are proven effective. Prior to the inception of the School Inner-City Asthma Study (SICAS-1), no American study had comprehensively evaluated the relationship between urban exposures in school, classroom, and home environments and asthma morbidity. Nearly all elementary school children spend 6 to 10 hours a day in school, and most of that time is spent in one classroom. From SICAS-1, we learned that student classroom-specific mouse allergen, mold, and particulate pollutant exposure is associated with worsening symptoms. We also demonstrated our ability to reduce these exposures in a busy, school setting. Our proposal builds upon our established, successful school-based infrastructure to determine whether a school/classroom intervention will efficiently and effectively improve asthma morbidity by reducing these exposures. Our goal is to determine the efficacy of school/classroom based environmental intervention in reducing asthma morbidity in urban schoolchildren. Our central hypothesis is that reducing classroom/school exposure to mouse allergen, mold, and particulate pollutants will decrease asthma morbidity in students with asthma. We plan to test this hypothesis in an intervention study of 300 elementary students with asthma from multiple classrooms in 40 Boston inner-city elementary schools. Our clinical trial aims are to determine the effectiveness of a school/classroom based environmental intervention (school integrated pest management and classroom air purifying filter units within these schools) to reduce asthma morbidity.This study is an unprecedented, high impact opportunity to test whether we can efficiently benefit a community of children in the school environment as opposed to individuals in single homes. It also adds a novel mechanistic application on health outcomes. It efficiently tackles a critical public health problem that affects a growing proportion of disadvantaged, urban U.S. children.
