University of Maryland (UMD) School of Public Health doctoral student Ms. Jessica Montresor-Lopez received an associate member travel award from the American College of Epidemiology (ACE) conference in recognition of her research, “Short-term effects of ambient ozone on stroke risk in South Carolina”. Ms. Montresor-Lopez’s abstract, which describes the research conducted for her MPH thesis, ranked second out of all abstracts submitted by associate members.
Although recent reports have suggested that exposure to ozone air pollution is associated with stroke events, findings have been inconsistent, according to her research. Ms. Montresor-Lopez used a case-crossover study design to explore the association between acute ozone exposure and risk of stroke hospitalization among South Carolina residents, taking race and gender into consideration.
Her research shows that for total stroke (ischemic and hemorrhagic combined), a 10 ppb increase in ozone exposure on the day of hospitalization was associated with an increased risk of stroke hospitalization. She observed subtle differences among women, who have a slightly lower risk than males. For hemorrhagic stroke, the magnitude of the association differed by race for all time periods of ozone exposure considered.
Ms. Montresor-Lopez completed her MPH in environmental health in 2013, and is now in the PhD program in Toxicology and Environmental Health. She is advised by Dr. Robin Puett, assistant professor in the Maryland Institute of Applied Environmental Health.
