Component Description

The prostate questions in the Kidney Conditions section (variable name prefix KIQ_P_D) 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 years and older 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_D) section, please refer to the NHANES 2005-06 Interview Procedure Manuals 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 QA/QC process for this component, please refer to the NHANES 2005-06 Interviewer Procedure Manuals on the NHANES website.

Analytic Notes

2005-06 changes

The Prostate Conditions questions were previously administered through an audio computer-assisted self interview (ACASCI) in the MEC. These questions are now asked in the Kidney Conditions section of the MEC Interview together with the urinary incontinence and nocturia questions.

Question KIQ490 is comparable to KIQ106 asked previously. The question name was changed for administrative purposes only.

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.
