Spatial Analysis of Traffic-Related Exposures and Respiratory Outcomes in Children

Read about Dr. Beamer

Dr. Beamer is another colleague in the College of Public Health that the SWEHSC has been able to recruit via a Pilot Project. Dr. Beamer is actually an engineer who does environmental exposure studies with various populations. This project partnered with the Tucson Children’s Respiratory Study (CRS) to study the importance of air pollution and diesel exposures early in life on development of asthma and wheezing disorders. The CRS is a longitudinal birth cohort study that enrolled 1246 infants from 1980 to 1984 to examine relationships between potential risk factors, lower respiratory infections (LRIs) and development of respiratory disorders. Utilizing data from the CRS, Dr. Beamer analyzed the relation of traffic-related exposure at birth with occurrence of LRIs during the first three years of life and persistence of wheeze through adolescence. She used GIS software to develop an integrated traffic exposure variable for each child based on traffic density within a circular buffer of the child’s birth address. To assess any geographic predictors associated with other environmental exposures, she completed spatial analyses of the occurrence of LRIs. Dr. Beamer received an outstanding impact/priority score of 19 on a pending NHLBI K25 Grant “Role of Traffic Related Exposures in Development of Asthma Precursors in Children”, which was a direct result of this pilot project.  The nature of the environmental exposure and use of the CRS study had particular interest for the IHS. Dr. Beamer is a current member of RFG 2.
