Asthma prevalence increased from 2001 to 2010: An estimated 25.7 million persons had asthma in 2010. Certain demographic groups had higher asthma prevalence: children aged 0–17 years, females, black persons, persons of multiple race, Puerto Rican persons, and persons with a family income below the poverty level. This report examines rates for asthma outcomes (health care encounters and death) for persons with asthma rather than for the general population. Rates for the general population represent the burden of asthma in the United States. Rates for the population with asthma take into account changes in asthma prevalence over time and differences in asthma prevalence among demographic groups. From 2001 to 2009, rates for ED visits and hospitalizations per 100 persons with asthma remained stable, while rates for asthma visits in primary care settings (physician offices or hospital outpatient departments) and asthma deaths declined. For the period 2007–2009, asthma visit rates (per 100 persons with asthma) in primary care settings for black persons were similar to those for white persons, but rates for asthma ED visits, hospitalizations, and death (per 1,000) were higher. Compared with adults, children aged 0–17 years had a higher rate for asthma visits in primary care settings and EDs, but had a similar hospitalization rate and a lower asthma death rate.
