Component Description

The Kidney section (prefix KIQ) provides personal interview data on kidney disease, prostate disease, urologic symptoms, and rectal examinations.

Eligible Sample

 All participants 20 years of age and older are asked a question about kidney disease and bladder control (KIQ020).

All participants 60 years of age and older are asked about bladder control problems (KIQ040 – KIQ060).

Men 60 and older are asked about other urologic symptoms (KIQ080 – KIQ100).

Men 30 and older are asked several questions about prostate disease (KIQ120 – KIQ320).

All participants 30 years of age and older are asked about rectal examinations (KIQ340 – KIQ380).

Analytic Notes

Similar questions were asked of some age groups during the Mobile Examination Center private interview. The questions were repeated for some age groups to determine if participants provided the same answers to sensitive questions in different interview settings.
