Percentage with uncontrolled asthma: Children
Percentage with uncontrolled asthma: Adults
Asthma control reflects the level of minimizing the frequency and intensity of symptoms and functional limitations. Uncontrolled asthma* has a significant cost to families and society, since it relates to an increase in emergency department visits, hospitalizations, and work and school absenteeism.
On average, 38.4% of children and 50.0% of adults with current asthma† had uncontrolled asthma during the years 2006-2010. The level of asthma control varied by state, but did not follow a specific geographic pattern. Percentages of children with current asthma who had uncontrolled asthma ranged from 26.7% in Pennsylvania to 53.1% in Mississippi. Pecentages of adults with current asthma who had uncontrolled asthma ranged from 34.9% in DC to 63.9% in Alabama.
