AsthmaStats provides national and state level estimates among children and adults on asthma-related specific topics using data from National Center for Health Statistics (NCHS) surveys, the Vital Statistics System, and the BRFSS Asthma Call-back Survey (ACBS).
Nearly half the people with current asthma had one or more asthma attacks in the past 12 months
In an asthma attack, the airways become inflamed, making breathing difficult. On average, 50.2% of children and 44.7% of adults with current asthma had one or more asthma attacks during 2014–2017. The percentage of asthma attacks varied by state. Among children, the median percentage was 51.0%, but it ranged from 23.1% in Nebraska to 81.7% in Wyoming. Among adults, the median percentage was 44.8%, but it ranged from 32.7% in North Dakota to 66.6% in Alaska.
