Environmental Influences on Childhood Asthma Prevalence in Philadelphia

BackgroundIn 2019, the American Lung Association found that, for the second year in a row, the Philadelphia metro has worsened the surrounding areas air quality, due to worsening ozone smog. This spike in unhealthy air quality in Philadelphia has affected the health of the citys population. Unhealthy air quality can be exacerbated by asbestos, which has been found in many Philadelphia elementary schools. Although asbestos usage is now highly regulated, it can still be found in consumer products and construction material today. Among the many factors contributing to asthma onset and other lung diseases, air pollution and dangerous air particles such as asbestos are important contributors. Children in these asbestos infected schools became exposed and ultimately sick which led to their schools eventual closure. Due to childrens immature and more vulnerable airways, this exposure may have led to increasing cases of respiratory distress. MethodsThis research study analyzed publicly available asbestos data from Asbestos Hazard Emergency Response Act (AHERA) reports from four Philadelphia elementary schools (Laura H. Carnell, James J. Sullivan, Clara Barton, and Thomas M. Peirce) from 2016-2018 to further understand the influence of asbestos particles on asthma in children. Secondary data analysis determined the levels of asbestos contamination in each elementary school and the severity of the condition for each school. This was compared to childrens asthma prevalence during the selected time period. ResultsAsbestos was mainly found in the 2-6 inch pipe insulation and tiles within each school. Between 0.06 and 1.18% asbestos damage was found in 2-6inch pipe insulation in schools closed for asbestos abatement. An r2 of 0.9997 was found when comparing the 206inch pipe damage percentage and the newly friable material found in each school. Thomas M. Pierce Elementary was determined to be the highest concern according to the analysis of the AHERA reports. ConclusionChildren exposed to asbestos in elementary schools, and with a predisposition to asthma, were more likely to suffer from respiratory distress, due to the multiple contributing environmental factors.
