About the National Data
Data source: National Health Interview Survey (NHIS), CDC/NCHS
Baseline: 41.5 percent of persons with current asthma had an asthma attack in 2019
Target: 35.1 percent
Participants who had ever been told by a doctor or other health professional that they had asthma and reported that they still have asthma were considered to have current asthma. Includes persons with at least one asthma attack in the past year.
In 2021, due to the 2019 NHIS redesign, the baseline was revised from 45.2% in 2017 to 41.5% in 2019. The target was revised from 38.1% to 35.1% using the original target setting method.
Because Healthy People 2030 objectives have a desired direction (e.g., increase or decrease), the confidence level of a one-sided prediction interval can be used as an indication of how likely a target will be to achieve based on the historical data and fitted trend.
