Codes and Frequencies
For sample adults and sample children who were ever told by a doctor or other health professional that they had asthma (ASTHMAEV), ASTHATAKYR identifies those who had an asthma attack/episode during the past 12 months.
Those who responded affirmatively to ASTHATAKYR were asked a follow-up question about whether they "had to visit an emergency room or urgent care center because of asthma" during the past 12 months (ASTHERYR).
Other asthma-related questions were periodically included in the survey; see ASTHMAEV for a summary of these variables currently in the IPUMS NHIS.
This variable is completely before 2019.
The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
