Description
For sample children and sample adults who have been told by a doctor or other health professional that they had or likely had coronavirus (CVDDIAG) or tested positive for COVID-19 (CVDTESTRSLT), CVDSYMP describes their coronavirus symptoms when they were at their worst.
NCHS added nearly 30 questions related to COVID starting in quarter 3 of the 2020 NHIS questionnaire, eight of which are asked of both sample adults and sample children. For the full list of variables, as well as information about COVID-related changes to the NHIS, please see the user note.
Analysts will need to adjust the sampling weights to account for the limited collection period and sample changes in 2020. For an example of how to do this, including sample code, please see the sampling weight adjustment section of the Variance Estimation User Note.
