Description
For persons who were in scope and were ever diagnosed with asthma (ASTHMAEV or ASTHMARD) and who reported having a peak flow meter at home (ASTHPEAKHM)and used their peak flow meter (ASTHPEAKUS), ASTHPEAKLS reports if they used it 'Within last 7 days', '7+ days, within last 30 days', or 'More than 30 days'.
Collection frequency and timing for ASTHPEAKLS changes over time. This variable was collected annually in 2003-2006, 2018, 2019, and 2022 forward. In other years, this question was fielded more than once per year and those responses are recorded in the round-level variable ASTHPEAKLSRD.
ASTHPEAKLS is one of several asthma-related questions included in the Priority Conditions Enumeration (PE) section. For a complete list of these variables, please see the variable description for ASTHMAEV.
