Description

For sample persons age 18 and older who currently smoke some days or every day (SMOKFREQNOW), CSQSTOP12M indicates if, during the past 12 months, the person ever stopped smoking for one day or longer because they were trying to quit smoking. Before 2020, CSQSTOP12M indicates if, during the past 12 months, the person ever stopped smoking for one day or longer, but does not include the additional stipulation that it was because they were trying to quit smoking.

Beginning in 2020, CSQSTOP12M was collected as part of the NHIS rotating core content on smoking history and cessation. For more information on the smoking history and cessation rotating core or other smoking history and cessation variables, please see SMOKAGEREG.

Comparability

In addition to minor changes in the universe, the comparability of CSQSTOP12M over time is affected by major changes to NHIS data collection introduced in 2019. Changes in survey design (e.g., quarters in which the supplement was collected) may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IPUMS NHIS weights.

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.
