Component Description

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. Data collected in 2019-March 2020 can be accessed as convenience samples through the NCHS Research Data Center (RDC). Any analyses based solely on the 2019-March 2020 data would not be generalizable to the U.S. civilian non-institutionalized population. Please refer to the Analytic Notes section for more details on the use of the data.

The standing balance section (variable name prefix BAQ) provides personal interview data on self-reported prevalence of balance, dizziness, and falls. The questionnaire was developed with expert consultants from the National Institute on Deafness and Other Communications Disorders (NIDCD). Data collection for the NHANES 2019-2020 cycle also included a balance examination component and these data will be available in a separate file.

Eligible Sample

All survey participants aged 40 years and older in the NHANES 2019-March 2020 convenience sample were eligible.

Interview Setting and Mode of Administration

This questionnaire section was conducted, in the home, by trained interviewers using the Computer-Assisted Personal Interview (CAPI) system. Hand cards showing response categories were used for some questions. A proxy provided information for survey participants who could not answer the questions themselves.

Quality Assurance & Quality Control

The CAPI system is programmed with built-in consistency checks to reduce data entry errors. CAPI also uses online help screens to assist interviewers in defining key terms used in the questionnaire. All data was reviewed by the NHANES field office staff for accuracy and completeness.

Data Processing and Editing

Frequency counts were checked, “skip” patterns were verified, and the reasonableness of question responses was reviewed. Edits were made to some variables to ensure the completeness of the data. Edits were also made, when necessary, to address data disclosure concerns. Specifically, for BAQ350 (age when this first experienced the symptom), any reported values of 17 years and younger were coded as 17 years and younger. All responses of age 80 years and older for BA350 are coded as 80, to be consistent with the coding for the participant age variable in the demographics file.

Self-reported data collected asking similar questions but with different recall periods may result in apparent discrepancies. No edits were made to resolve any of these possible discrepancies. For example, BAQ311(ever problem with dizziness/balance) was not edited based on responses to BAQ320a, BAQ320b, BAQ320c, BAQ320d, BAQ320e, BAQ320f, or BAQ320g (symptoms of dizziness, light-headedness, or balance problems in the last 12 months). As another example, BAQ530 (number of falls in the past 5 years) was not edited based on responses to BAQ550 (number of falls in the past 12 months). However, analysts may consider recoding variables for their analyses.

Analytic Notes

The COVID-19 pandemic required suspension of NHANES 2019-2020 field operations in March 2020 after data were collected in 18 of the 30 survey locations in the 2019-2020 sample. Data collection was cancelled for the remaining 12 locations. Calculation of survey weights for this partial cycle is not possible due to incomplete data collection. Therefore, data from survey components that were only collected in 2019-March 2020 are made available as convenience samples through NCHS's Research Data Center (RDC) because unbiased estimates for the NHANES target population cannot be produced with these samples.

For survey components conducted in both 2017-2018 and 2019-2020 cycles, data collected from 2019 to March 2020 were combined with data from 2017 to 2018 to form a nationally representative sample of NHANES 2017-March 2020 pre-pandemic data. Please see the NHANES 2017-March 2020 pre-pandemic data page for detailed information on this combined sample. However, BAQ was not inlcuded in 2017-2018 so a combined NHANES 2017-March 2020 pre-pandemic file was not created.
