Component Description

The Diabetes section (prefix DIQ) provides personal interview data on diabetes, use of medications, and symptoms associated with diabetes such as vision problems, foot ulcers and sensations in the extremities.

Eligible Sample

All participants 1 year of age and older are eligible for the lead-in question
pertaining to history of diabetes.

Follow-up questions:

Interview Setting and Mode of Administration

The DIQ section is administered in the home by a trained household interviewer. This information may be linked to data obtained during the health examination component. An assessment of lower extremity disease (LED) and peripheral neuropathy is performed in adults 40+ years of age. Please refer to the notes for the LED component.

Quality Assurance & Quality Control

Questionnaire data is systematically reviewed for logical, processing, and data input errors on a periodic basis during the process of data collection.

The computer CAPI system had built-in consistency checks, online information screens that provided the interviewers with information about the terms used in the questionnaires, and hard and soft edit checks to reduce the number of keying entry errors. All of the interviews were reviewed by the NHANES field office staff for accuracy and completeness.

Analytic Notes

For the following derived variables, when “don’t know” was entered as the response to a quantity question, the data were back coded to reflect “don’t know” in the gate question (enter number, less than 1, refused, don’t know) and the “don’t know” response was changed to missing in the quantity variable.

DID040G / DID040Q

DID060G / DID060Q

Only records for eligible participants are included in this file.

Please refer to the Analytic Guidelines for further details on the use of sample weights and other analytic issues at http://www.cdc.gov/nchs/data/nhanes/nhanes_general_guidelines.pdf.
