Brief Summary:
This study surveys the parentsguardians about symptoms and diagnosis of asthma in kindergarten and first-grade students in 13 schools around the city of Anchorage Alaska Traffic information is also measured and entered in geographical information mapping system with students home and school locations The study will assess whether students living in high traffic areas have greater risk of diagnosis of asthma
Detailed Description:
Survey was distributed through the schools Parentsguardians were asked about indoor exposures such as environmental tobacco smoke insects mold woodstoves as well as demographic information about the child and housing type incomealso biologic information about parental asthma Questions included symptoms of respiratory illness as well as wheezing and medication use Civil engineering department measured traffic on local roadways and gathered traffic information from state and municipal sources regarding traffic on arterioles and major traffic arteries All information was entered into geographical information system GIS including the closest cross-streets to the childs home and the school location Traffic exposure variables are being developed for each child and will be added to the database on indoor exposures A regression model will be used to determine the significance of traffic exposure in receiving a diagnosis of asthma for children five to seven years of age
