Component Description

The NHANES 2009-20010 Kidney Conditions – Urology File provides personal interview data on kidney disease, kidney stones, urinary incontinence, and nocturia. Personal interview data on prostate conditions can be found in the Prostate Conditions File, KIQ_P_F.

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, dialysis, kidney stones, and passing a kidney stone (KIQ022, KIQ025, KIQ026, KID028) were asked in the home by trained interviewers using a Computer-Assisted Personal Interviewing (CAPI) system.

Questions on urinary incontinence (KIQ005, KIQ010, KIQ042, KIQ430, KIQ044, KIQ450, KIQ046, KIQ470, KIQ050, KIQ052) and nocturia (KIQ480) were administered in the Mobile Examination Center (MEC) during the MEC Interview by trained interviewers using a CAPI system.

For details on the administration of the Kidney Conditions – Urology (KIQ_U_E) section, please refer to the NHANES 2009-2010 Interviewer Procedure Manuals, MEC Interviewer Exam Manual, and the Kidney Conditions Sample Person and CAPI Questionnaires 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 control/quality assurance process for this component, please refer to the NHANES 2009-2010 Interviewer Procedure Manuals on the NHANES website.

Data Processing and Editing

Frequency counts were verified during the preparation of the file.

Analytic Notes

Missing data

Although KIQ005 – KIQ480 were targeted to all participants 20 years and older, data for these questions are missing for 9.6% of individuals who completed the household interview, but did not complete the MEC CAPI.

Appropriate sample weights

Interview weight:  KIQ022- KID028

Examination weight:  KIQ005-KIQ480

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

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.
