Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
From the 2008 National Health Interview Survey Asthma Supplement:
For persons under age 18 years:
Has [PERSON] EVER taken a course or class on how to manage [his/her] asthma?*Include adult(s) who took a course for the child's asthma.
For persons aged 18 years and over:
Have you ever taken a course or class on how to manage asthma yourself?
[NUMERATOR AND DENOMINATOR:]
Has a doctor or other health professional EVER told you that [PERSON] had asthma?
Does [PERSON] still have asthma?
Have you EVER been told by a doctor or other health professional that you had asthma?
Do you still have asthma?
Persons are classified as having received formal education on asthma if they reported taking a course or class on self- management. This includes adults who took a course for a child.
To maintain consistency with the Council of State and Territorial Epidemiologists (CSTE), the case definition for asthma is based on ‘current’ asthma (yes to ‘ever asthma’ and yes to ‘still asthma’).
This Indicator uses Age-Adjustment Groups:
Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.
In 2013, the target was revised from 14.4 to 14.5 percent due to a change in the rounding rules for target calculations of Minimal Statistical Significance.
