In 2002 and 2007, BOWELIRINFEV identifies sample adults who were ever told by a doctor or other health professional that they had inflammatory bowel disease, irritable bowel, or constipation severe enough to require medication. Respondents with an affirmative response in BOWELIRINFEV were asked if they had each of the conditions during the past 12 months. In 2007, sample adults who had the condition during the past 12 months were asked whether the specific condition they experienced was inflammatory bowel disease (BOWELINFYR), irritable bowel (IRRBOWELYR), or constipation severe enough to require medication (BOWELCONYR).
