Component Description

The Blood Pressure/Cholesterol section (variable name prefix BPQ) provides personal interview data on awareness, treatment, and control of high blood pressure and high cholesterol.

Eligible Sample

Participants aged 16 years and older were eligible.

Interview Setting and Mode of Administration

These questions were asked, in the home, by trained interviewers using the Computer-Assisted Personal Interview (CAPI) system.

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 of the data were reviewed by the NHANES field office staff for accuracy and completeness.

Data Processing and Editing

Edits were made to ensure the completeness, consistency, and analytic usefulness of the data.

Analytic Notes

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.

In order to prevent possible disclosure, values of BPD035 less than 12 were recoded to 12 and values greater than 80 were recoded to 80.

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