Ammons, SamanthaBackground: The concentration of privilege in a geographic area can determine how vital resources are distributed among certain groups in that area, thus influencing a community’s health. High air pollutant exposure is often concentrated in deprived neighborhoods with lack of vital resources. Objective: Determine whether states with a high concentration of air pollution exposure have higher infant mortality rates (IMR) than states with lower concentrations of air pollution exposure. Methods: The Index of Concentration of the Extreme was utilized to measure the concentration of air pollution exposure for each state. Incidence Rate Ratios and 95% Confidence Intervals for state infant mortality rate were computed using Poisson regression in Statistical Analysis Software. Results: States with high concentrations of air pollution exposure had 19% lower IMR than states with low air pollution exposure (95%CI:0.70 – 0.94). Conclusions: These findings can enable researchers to conduct census-tract research on adverse health outcomes and societal distributions.enUsing the Index of Concentration at the Extremes to Examine the Impact of Air Pollution Exposure on Infant Mortality in the United StatesThesisEpidemiologyPublic healthEnvironmental justiceAir Pollution ExposureAir Quality IndexEnvironmental JusticeEpidemiologyInfant MortalityPrivilege
