Effect of Weather and Ozone Concentrations on the Occurrence of Stroke Death

People all over the world are experiencing strokes and sometimes die from them. The aim of this study was to clarify whether air pollution, weather, and the incidence of stroke mortality can be correlated as some recent studies have shown. Scientists are puzzled by the occurrence of stroke daily among hundreds of people in the U.S. More research is needed to find the possible risk factors for stroke. To begin, monthly averages of meteorological factors were obtained for the years 2001 and 2002. Furthermore, unhealthy exceedances of ozone concentrations were acquired along with stroke deaths. This data regarded six counties in New Jersey: Essex, Sussex, Morris, Bergen, Camden, and Cape May. This data was then tabulated into Excel and correlated using the Pearson Correlation. Results indicate an inverse relationship between temperature and stroke deaths. However, results also determined that a relationship between ozone concentrations and stroke deaths does not exist. Therefore, the second hypothesis is corroborated, that the fluctuation of weather will result in the fluctuation of stroke death. The study reveals that weather may be risk factors for stroke. In order to gain a better understanding of grasping such a correlation, further research should be undertaken, inclusive of studying stroke subtypes, other meteorological factors, socioeconomic factors, and a larger sample size.
