Description
INSULIN reports responses to the question, "Are you now taking insulin?" The U.S. Food and Drug Administration website on diabetes information notes that insulin is taken by diabetics to control blood sugar levels and that insulin cannot be taken by mouth because it would be destroyed by digestion. Instead, insulin is injected through shots or other devices such as insulin pens, jet injectors, or pumps.
Respondents who received the question associated with INSULIN were also asked if they were currently taking diabetic pills, also called oral agents or oral hypoglycemic agents, to lower their blood sugar (DIAPILLS).
Comparability
Apart from universe changes, the INSULIN variable is completely comparable over time.
Universe Changes
In 1997-2005, the question for INSULIN was asked of sample adults who were ever told by a doctor or other health professional that they had diabetes (other than during pregnancy) (DIABETICEV). In 2006, the question was asked of all sample adults. The 2006 Field Representative's Manual provides the following explanation for the universe change put in place that year:
In 2007, the universe for INSULIN was redefined to cover sample adults who had ever been told they had diabetes (other than during pregnancy) or that they had a prediabetic condition, including prediabetes, impaired fasting glucose tolerance, borderline diabetes, or high blood sugar (DIAPRECOND).
