Component Description

The Immunization section (prefix IMQ; questions IMQ.010 to IMQ.030) provides sample person interview data on immunization with the hepatitis A and hepatitis B vaccine for participants age 2 and above. The number of doses received is also obtained since both vaccines are multi-dose. For minors, the questions were answered via a proxy respondent, generally a parent or guardian. Individuals age 20 or more years are asked if they ever had the pneumococcal vaccine.

Eligible Sample

All survey participants 2 years of age and older are asked about hepatitis A and B vaccination. All survey participants 20 years of age and older are asked about pneumococcal vaccination.

Interview Setting and Mode of Administration

Household questionnaire -- In-person.

The Interviewer Procedure Manuals and Survey Questionnaires and Exam Manuals can be found on the NHANES website.

Quality Assurance & Quality Control

No component specific quality control.

Data Processing and Editing

A subject’s questionnaire interview responses were entered into a laptop computer and then uploaded to the NHANES computerized database in the same manner as other sections of the Sample Person Questionnaire. The data were edited for completeness, consistency, and illogical values.

Analytic Notes

IMQ questionnaire data was collected on a full sample of respondents and can be analyzed in conjunction with results from MEC laboratory data, which has measures of hepatitis A antibody (on those age 6 or more years, LBXHA) and hepatitis B surface antibody (on those age 2 or more years, LBXHBS). Antibody to Pneumococcal pneumonia was not measured during the survey. Analysts should review all NHANES laboratory 2 (Hepatitis Laboratory) data release documentation and statistical and analytic guidelines prior to beginning data analysis.

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

Please refer to the Analytic Guidelines for further details on the use of sample weights and other analytic issues at http://www.cdc.gov/nchs/nhanes/survey_methods.htm.
