Methodology Notes

Persons are classified as having an activity limitation if they responded that lung/breathing problems caused limitations.

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’).
