Insights into asthma prevalence in Oregon

Abstract

Asthma is one of the most common chronic diseases. The prevalence of asthma appears to be increasing. National data have suggested that Oregon's asthma mortality rate has been twice as high as the national average. The prevalence and impact of asthma are not systematically assessed or tracked within Oregon. We estimated the current asthma prevalence and mortality using data from statewide hospital discharge data, the 1995 Behavioral Risk Factor Surveillance Survey, and school registration data from the Portland area. A conservative estimate of Oregon's current asthma prevalence is 6-7% and lifetime asthma prevalence is estimated at 6-11% for both adults and children. It appears that current asthma prevalence increases during adolescence. The Willamette Valley, an area known for high pollen counts, does not have a higher rate of hospital discharges per capita than other areas within the state. Oregon's apparent higher asthma mortality may be the result of the Oregon State Health Division's aggressive policies toward accurate reporting on death certificates. Oregon's age distribution may also contribute to the apparent higher asthma mortality rate.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
