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.

The Program conducts national asthma surveillance and provides funds to states to help improve asthma surveillance and focus efforts and resources where they are needed.
