Objective:

The overall objective of this proposal is to assess the relationship between exposures to ambient levels of certain urban air toxics, as measured by outdoor air monitors, and utilization of urgent care facilities by children enrolled in Medicaid in Dearborn, Michigan. The two principal hypotheses and related aims follow:
 
Hypothesis 1: Levels of selected urban air toxics, including 1,3-butadiene, acetaldehyde, acetonitrile, benzene, carbon tetrachloride, chloroform, formaldehyde, methylene chloride, tetrachloroethene, and trichloroethene, are related to measures of urgent care utilization for asthma among a pediatric Medicaid population in Dearborn, MI.
 
The specific aims are to:
Develop a set of exposure measures based on daily measurement data of the selected UATs available at the Dearborn monitor between April 19, 2001, and April 19, 2002, along with other pollutants known or likely to be associated with asthma (O3, PM, etc.).
1.   Obtain Medicaid files on children from 1 –17 years of age residing in Dearborn between April 19, 2001, and April 19, 2002, on daily utilizations of urgent care facilities, including hospital visits and urgent care visits.
2.   Link the exposure measures and Medicaid files.
3.   Analyze the relationships between daily fluctuations in concentrations of the UATs and daily urgent care utilization for asthma using appropriate statistical models.
 
Hypothesis 2: Urban air toxics concentrations represent contributions from various emission source groupings that in turn are related to urgent care utilization for asthma among the same pediatric Medicaid population.
 
The specific aims for this hypothesis are:
1.     Develop daily source apportionment scores for the selected Dearborn UATs using multivariate models and ambient air quality data.
2.     Analyze the relationship between source category scores and urgent care utilizations for asthma using appropriate statistical models.
3.     Assess the variability in the apportionment scores using alternative method to derive the source scores.
4.     Assess the variability in the apportionment scores using alternative method to derive the source scores.

Summary/Accomplishments (Outputs/Outcomes):

·      The study was funded in response to RFA 2003, “Small Grants Program on Exposures and Health Effects of Urban Air Toxics.”
·      The study is in compliance with Institutional Review Board of the University of Michigan. The study provided and followed appropriate quality control and quality assurance procedures.
·      The study started in December 2004 and was scheduled to be completed in December 2006.
·      A no-cost extension was given to this project through June 2007.
·      A draft final report was submitted to the NUATRC in March 2007.
·      A revised final report was received by the Center in February 2008.
·      The Center Research Report Number 14, “Impact of Exposure to Urban Air Toxics on Asthma for the Pediatric Medicaid Population in Dearborn, Michigan,” was published in 2008.
