Impact/Purpose:
Asthma is the most common chronic disease of children in the US. Mold and particulate exposures have been linked to asthma development and/or exacerbation. In this study in the under-resourced Sun Valley neighborhood in Denver CO, we quantified the mold and particulate exposures in the current homes. A retrospective analysis (2015-2019) of use of Medicaid and Medicare Insurance for health conditions, like asthma, was performed to compare Sun Valley residents to all Denver residents. We found that the mold and particulate levels in Sun Valley homes was much higher than for the the average US home. Also, the use of Medicaid and Medicare for health conditions like asthma was significantly greater for the residents of Sun Valley than for Denver residents. Our goal is to repeat this analysis once the Sun Valley residents have moved into their new homes. This kind of information should provide support for policy makers and housing advocates to promote safe housing.
Description:
The Sun Valley Homes public housing in Denver, Colorado (CO) will be replaced because of its deteriorated condition. Our goal was to document the mold contamination and particulate matter (PM2.5) concentrations in Sun Valley homes and the circulatory and respiratory health of Sun Valley compared to all Denver residents (total 2761 and 1,049,046, respectively) based on insurance claims data for 2015 to 2019. Mold contamination in Sun Valley homes (n = 49) was quantified using the Environmental Relative Moldiness Index (ERMI) scale. Indoor PM2.5 concentrations were measured in Sun Valley homes (n = 11) using time-integrated, filter-based samples and quantified using gravimetric analysis. Outdoor PM2.5 concentrations data were obtained from a near-by United States Environmental Protection Agency monitoring station. In Sun Valley homes, the average ERMI value was 5.25 compared to −1.25 for other Denver homes. The PM2.5 median concentration inside Sun Valley homes was 7.6 μg/m3 (interquartile range - 6.4 μg/m3). The ratio of indoor to outdoor concentrations of PM2.5 was 2.3 (interquartile range - 1.5). In the last five years, ischemic heart disease was significantly more likely for Denver compared to Sun Valley residents. However, acute upper respiratory infections, chronic lower respiratory diseases and asthma were all significantly more likely for Sun Valley than Denver residents. Since the process of replacing and occupying the new housing will take several years, the next phase of the study will not occur until that process is complete.
