Balance (BAQ_B)

Data File: BAQ_B.xpt

First Published: May 2004

Last Revised: NA

Component Description

The Balance Questionnaire (variable name prefix BAQ) provides sample person interview data on the self-reported prevalence of balance, dizziness, and falls. This is of importance because of the increasing morbidity and mortality associated with balance disorders among older persons in the U.S.

Topics Included in the Section:

1 month period prevalence of dizziness, balance problems and falls
Duration of the balance problems listed above
Self-reported reason for balance or dizziness problem
History of medical treatment for balance/dizziness, type and outcome
Family history of balance, dizziness or falling problem

Questionnaire Source(s):

All the questions in the current NHANES balance questionnaire were newly developed for this survey in consultation with expert consultants from the National Institute on Deafness and Other Communications Disorders (NIDCD).

Links to examination and laboratory data:

Balance Physical Examination data are found in the Balance Section of the NHANES 2001-2002 Examination Files.

Eligible Sample

All sample persons 40 years of age and older were asked these questions. There were no exclusions for this questionnaire segment.

Interview Setting and Mode of Administration

Home Interview; In-person.

Quality Assurance & Quality Control

Balance questionnaire data was systematically reviewed for logical, processing and data input errors on a periodic basis during the process of data collection.

Data Processing and Editing

The 2001-2002 Balance Questionnaire data was verified prior to public release.

Analytic Notes

Balance data analysis is a complex, and requires knowledge of the specialty content area for valid results to be obtained. If an analyst does not have professional experience in this area, it is recommended that specialty consultation be obtained to help formulate and review the results of the analysis.

Data Access:

The BAQ data are publicly available at www.cdc.gov/nchs/nhanes.htm except for detailed data for BAQ080B and BAQ080C. Requests for this data should be made to the NHCS Research Data Center.
