Study: Fine Particulate Air Pollution and Hospital Admission for Cardiovascular and Respiratory Diseases

This study, which can be found in the March 8, 2006 issue of the Journal of the American Medical Association, compared air pollution levels to the number and types of hospitalizations occurring at the same time. The study’s author, Francesca Dominici, an associate professor of biostatistics at Johns Hopkins University’s Bloomberg School of Public Health, used information from an air particulate matter monitoring system and compared it to daily rates of hospitalizations for a number of different conditions, including injuries, cardiovascular diseases and respiratory diseases. The hospitalization information came from records of more than 11.5 million Medicare enrollees, who were 65 years and older. The results demonstrate that a 10 micron per cubed meter increment increase in the air pollution level results in about 11,000 extra hospitalizations for cardiovascular and respiratory disease.
