Asthma Severity among Children with Current Asthma
Asthma severity determines type and duration of treatment
Percentage with Persistent Severity
Asthma severity* is the inherent intensity of the disease process. Disease progression and symptoms vary among individuals and within an individual’s experience over time. The population-based asthma severity prevalence estimate depends on whether the individual is treated or not and how well the individual responds to the treatment. Intermittent severity includes people who are well-controlled without long-term control medication. Persistent severity includes people who are on long-term control medications and people with uncontrolled asthma (not well-controlled or very poorly controlled) who are not on long-term control medication. Nearly 60% of children with current asthma† have persistent asthma; 40% have intermittent asthma.
Intermittent and persistent asthma prevalence among children varied by state during the years 2006-2010, but did not follow a specific geographic pattern. Intermittent asthma prevalence ranged from 25.6% in Mississippi to 55.0% in Oregon (See table). Persistent asthma prevalence ranged from 45.0% in Oregon to 74.4% in Mississippi (See map for details).
