Children with asthma experienced fewer asthma attacks between 2001 and 2016, according to a recent Vital Signs report from the CDC.

The percentage of children with asthma who experienced one or more asthma attacks in the preceding 12 months fell from 61.7% in 2001 to 53.7% in 2016, according to the report. The decline was seen in both boys and girls and all races and ethnicities, Anne Schuchat, MD, RADM, USPHS, acting director of the CDC, reported at a press conference.

However, “not all news is good,” Schuchat said, noting that approximately half of children with asthma had one or more asthma attacks in 2016. Asthma attack prevalence increased significantly between 2001 and 2010, then decreased significantly between 2010 and 2016, she added.
