Component Description

The NHANES 2005-2006 Kidney Conditions – Urology File provides personal interview data on kidney disease, urinary incontinence, and nocturia. Personal interview data on prostate conditions can be found in the Prostate Conditions File, KIQ_P_D.

Questions KIQ.005 “How often do you have urinary leakage? Would you say …” and KIQ.010 “How much urine do you lose each time? Would you say…” comprise the Incontinence Severity Index (Sandvik, 2000). This index, based on information about frequency in four levels and amount of leakage in three levels, can be multiplied to obtain an index value (1-12). The four-level severity index is based on the following index values: 1-2, slight; 3-6, moderate; 8-9, severe; 10-12, very severe.

Eligible Sample

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

Interview Setting and Mode of Administration

Questions on kidney disease and dialysis (KIQ022, KIQ025) were asked during the in-person household interview.

Questions on urinary incontinence and nocturia (KIQ042–KIQ052) were asked in the mobile examination center (MEC) Interview Room using a Computer-Assisted Personal Interview (CAPI) system.

For details on the administration of the Kidney Conditions – Urology (KIQ_U_D) section, please refer to the NHANES 2005-06 Interviewer Procedure Manuals and the Kidney Conditions Sample Person and Computer Assisted Personal Interview (CAPI) Questionnaires on the NHANES website.

Quality Assurance & Quality Control

For details on the QA/QC process for this component, please refer to the NHANES 2005-06 Interviewer Procedure Manuals on the NHANES website.

Data Processing and Editing

Frequency counts were verified during the preparation of the file.

Analytic Notes

2005-06 Changes

Questions KIQ043, KIQ045, KIQ047, and KIQ048 were dropped. New urinary incontinence questions and a nocturia question were added: KIQ005, KIQ010, KIQ430, KIQ450, KIQ470, KIQ480. The urinary incontinence questions were asked of all participants 20 years and older in the MEC. Previously, participants 60 years and older were asked these questions in the household interview.

Missing data

Although KIQ042 – KIQ052 were targeted to all participants 20 years and older, data for these questions are missing for 12.7% of individuals who completed the household interview, but did not complete the MEC CAPI.

Appropriate sample weights

Interview weights:
KIQ022, KIQ025
Examination weights:
KIQ042 – KIQ052

The interview weight should be used when an analysis uses only data from the household interview. If an analysis uses data from the MEC (MEC interview, examination, or laboratory data on the full MEC sample) exclusively, or in conjunction with the household interview data, the examination weight should be used.

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.
