NHANES 2017-March 2020 Pre-pandemic
The NHANES program suspended field operations in March 2020 due to the coronavirus disease 2019 (COVID-19) pandemic. As a result, data collection for the NHANES 2019-2020 cycle was not completed and the collected data are not nationally representative. Therefore, data collected from 2019 to March 2020 were combined with data from the NHANES 2017-2018 cycle to form a nationally representative sample of NHANES 2017-March 2020 pre-pandemic data. Please see the links below for a brief overview and analytic guidance as well as a National Health Statistics Report on selected estimates for obesity, diabetes, hypertension, and oral health for additional information on the use of the data.
