Component Description

The diabetes section (variable name prefix DIQ) provides personal interview data on diabetes, prediabetes, and the use of insulin or oral hypoglycemic medications.

Eligible Sample

All survey participants aged 3 to 15 years were eligible. Please refer to check items in the diabetes questionnaire and corresponding codebook for question-specific details about the eligible target group.

Interview Setting and Mode of Administration

These questions were asked, in the home, by trained interviewers using the Computer-Assisted Personal Interviewing (CAPI) system. Hand cards showing response categories were also used for some questions. When necessary, household interviewers read the hand cards to respondents. A proxy provided information for survey participants.

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.

Data Processing and Editing

Frequency counts were checked, “skip” patterns were verified, and the reasonableness of question responses was reviewed. Edits were made to some variables to ensure the completeness, consistency, and analytic usefulness of the data. Edits were also made, when necessary, to address data disclosure concerns.

Analytic Notes

The analysis of NNYFS diabetes questionnaire data must be conducted using the appropriate survey design variables, sample weights, and the basic demographic variables. Although this data was collected as the part of the household questionnaire, if it is merged with the exam data, exam sample weights should be used for the analyses.

Please refer to the NNYFS Analytic Guidelines for further details on the use of sample weights and other analytic issues.
