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.
Analytic Notes
Question DIQ.090: "… ever had an ulcer or sore on (your/his/her) leg or foot that took more than 4 weeks to heal?
In the Spanish language version, the duration period was initially written as "2 weeks," but was corrected to "4 weeks" to match with the English language version. Data users should consider the possibility that the responses to DIQ090 reflect different time periods in the Spanish language version only.
DIQ010: “… ever been told by a doctor or health professional that {you have/{he/she/survey participant} has} diabetes or sugar diabetes?”
The questionnaire skip destination for responses “2,” “3,” “7,” and “9” were corrected from DIQ085 to DIQ050. Because of the correction in the skip patterns, there will be many missing values for DIQ050. All participants 1+ years were asked if they are “… now taking insulin.”
