Oral Health (OHQ_G)

Data File: OHQ_G.xpt

First Published: March 2014

Last Revised: NA

Component Description

The oral health questionnaire section (variable name prefix OHQ) provides personal interview data on oral health topics. These topic areas and related target population groups in the OHQ section include:

Last visit to dentist or lack dental care (1+ yr)
Direct conversation with dental professional about your dental health (16+ yr)
Dental health perception (1+ yr)
Oral cancer exam (30+ yr)
Use of dental floss or dental rinse product (30+ yr)
Periodontal disease self-report (30+ yr)

Eligible Sample

All survey participants aged 1 year and older were eligible for the dental health perception and quality of life related questions.

Interview Setting and Mode of Administration

The Oral Health questionnaire was done before the physical examination, in the home, using the Computer-Assisted Personal Interviewing-CAPI (interviewer administered) system.

Quality Assurance & Quality Control

Several types of quality control were implemented to ensure that high quality data were collected during the survey.

Interviewer monitoring was a major responsibility for NCHS and contractor staff. Interviewers were frequently accompanied on interviews and observed to verify that the interview protocol was administered correctly. Interviewers were retrained on survey procedures if necessary.

The interviewers are encouraged to provide comments and other suggestions, based on their field experiences. NCHS has used field staff and interviewer feedback to improve the questionnaires and survey materials. NCHS and contractor staff conduct annual staff debriefing and training sessions jointly. Interviewers are trained on new survey content and protocol changes prior to implementation in the field.

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.

Data Processing and Editing

Frequency counts were checked, "skip" patterns were verified, and the reasonableness of responses to the questions was reviewed.

Analytic Notes

In addition to the oral health questionnaire data, oral health examination data can be found in the oral health section of the NHANES Exam Files (OHX). These data may be linked using the unique survey participant identifier, SEQN. Please refer to the Oral Health Examination support documentation for additional information related to the oral component and oral health questions administered at the time of the oral health examination.

The check items (OHQ605, OHQ616, OHQ847 and OHQ890) are contained in the codebook as a guide to the user on how the skip patterns within the oral health questions work. Because there are no frequencies for these items they aren’t in the data file.

Although these data were collected as part of the household questionnaire, if they are merged with the MEC exam data, exam sample weights should be used for the analyses.

Please refer to the Analytic Guidelines and the on-line NHANES Tutorial on the NHANES website for further details on the use of sample weights and other analytic issues.
