Description

HEPATEV identifies sample adults (and, in 1989, sample children) who ever had hepatitis. The question wording, "Have you ever had hepatitis?," did not specify that the condition had to be diagnosed by a doctor or other health professional. In 2020, HEPATEV is only asked of sample adults interviewed in quarter 3 or 4.

Hepatitis, which was not defined in the survey documentation, is an inflammation of the liver caused by a viral infection.

Comparability

While the basic meaning of this variable is completely comparable over time, major questionnaire changes introduced in 2019 may affect 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.
