Description
For sample adults who felt very tired or exhausted some days, most days, every day, or don't know or refused to say how often they felt exhausted (TIREFREQ3MO), TIREDURALAST reports the duration of their exhaustion the last time they felt exhausted.
Beginning in 2020, TIREDURALAST is one of a set of rotating core variables on fatigue, collected every other year. For more information on the fatigue rotating core variables or about fatigue variables available in the NHIS prior to 2020, please see (TIREFREQ3MO).
Comparability
Changes in the survey design (e.g., the subsample for which the questions were administered) may affect raw frequencies. In 2010, this item was collected for sample adults who completed the Quality of Life supplement (administered to approximately a quarter of sample adults). In 2011-2017, this item was collected for sample adults who completed the Adult Functioning and Disability supplement (administered to a subset of sample adults). Beginning in 2018, this item was included on the sample adult questionnaire. Please refer to the Weights section for information about sample-specific weights. As always, users should employ the prescribed IPUMS NHIS weights.
Questionnaire design changes introduced in 2019 limit comparability with earlier years. 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.
