Other ongoing projects include research on whether some segments of the population face disproportionate health burdens from air pollution exposure, such as due to differences in biological susceptibility, baseline health status, or exposures. We found higher ozone-mortality effect estimates in communities with a higher proportion of racial minorities or lower income. Exposure patterns may also play a role, as we observed lower effects for communities with high prevalence of central air conditioning, which alters penetration of ambient air. Our studies of air pollution and birth weight also found differential effects by race, with higher impacts on infants of African-American mothers than White mothers. Currently, we are investigating how socio-economic status affects air pollution and weather-related mortality in Latin America and how air pollution effects differ by gender.
