Codes and Frequencies
DIABETICAGE reports age at first diagnosis by a doctor of "diabetes or sugar diabetes," for sample adults who were ever told by a doctor or other health professional that they had diabetes (other than during pregnancy alone) (DIABETICEV). Persons who reported their diagnosis as "borderline" diabetes were not asked this follow-up question. The Field Representative's Manual for 1997-2000 directed interviewers to probe for a specific age but to "record a best estimate if that is what the sample adult gives you."
The 2006 Codebook for the NHIS public use data files contains the following warning about inaccuracies in this variable:
