Component Description

The prostate questions in the Kidney Conditions section (variable name prefix KIQ_P_E) of the Mobile Examination Center (MEC) Interview provide personal interview data on prostate conditions and whether a rectal examination had been done to check for prostate cancer.

Additional questions on other tests for prostate cancer and treatments are released with the MEC Laboratory component: Prostate Specific Antigen (PSA) Exclusion Questions and Lab Results.

Eligible Sample

The target sample for the questions in this section is males 20 years and older.

Males 20-39 years of age were asked only KIQ490 “Have you ever been told by a doctor or other health professional that you have any disease of the prostate? This includes an enlarged prostate.”

Males 40 years and older were asked all questions in the section.

Interview Setting and Mode of Administration

The questions were asked in the MEC Interview, using an interviewer-administered Computer Assisted Personal Interviewing (CAPI) system.

For details on the administration of the Prostate Conditions (KIQ_P_E) section, please refer to the NHANES 2007-08 MEC Interviewer Exam Manual and the Kidney Conditions (KIQ) Computer Assisted Personal Interview (CAPI) Questionnaire on the NHANES website.

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.

For details on the quality assurance/quality control process for this component, please refer to the NHANES 2007-08 MEC Interviewer Manual on the NHANES website.

Data Processing and Editing

Frequency counts were verified during the preparation of the file.

Responses to KIQ161 “How old were you when you were first told that you had benign enlargement of the prostate gland?” were top coded at 80 years for consistency with the top-coded age of the survey participant.

Analytic Notes

Exam sample weights should be used for analyses. Please refer to the Analytic Guidelines for further details on the use of sample weights and other analytic issues. The Analytic Guidelines are available on the NHANES website.
