 During the 2005-2006 school year, primary caregivers of all students aged 4-17 years attending public school in Eudora and Marvell Arkansas were asked to complete an asthma screening survey regarding their child. The schools are located in two non-contiguous counties in the Delta region of Arkansas and are in rural low-income areas of the state where more than one-third of families with children 5-17 years old meet the 2000 poverty line Census bureau.
