Significant increases in asthma have been seen over a large portion of the United States from 2001 to 2008 according to a study preformed by researchers at the Centers for Disease Control and Prevention (CDC) and presented at the 2010 Annual Meeting of the American Academy of Allergy, Asthma & Immunology (AAAAI).
According to the study 19 states had significant increases in the 3-year average prevalence of asthma with the highest increases in Oklahoma and Alabama (both about 2%). The only state that demonstrated a decline over the 3 year period was Nevada.
In the press release lead study author Teresa A. Morrison, MD, MPH stated "This state-by-state analysis of annual trends in asthma prevalence is important for public health planning and for generating hypotheses to determine risk factors for this common condition."
