CDC Many Factors Affect IBD's Population Prevalence Federal survey data yield several surprises

Similar to previous reports, a higher prevalence of IBD was seen among adults ages 45 and older (3.2%), as well as among non-Hispanic whites (1.4%). But Dahlhamer and colleagues also found variations in certain subgroups that had not been previously reported. Adults with less than a high school level of education had a higher prevalence of IBD (1.7%) compared with those who had a bachelor's degree or higher (1.1%). Additionally, 1.6% of unemployed adults, compared with 1.2% of adults who were currently employed, reported ever receiving a diagnosis of IBD. Adults living in poverty (family incomes <100% of the federal poverty level) had a higher prevalence of IBD (1.8%) than adults from families with incomes ≥400% of the federal poverty level (1.1%). Regionally, adults living outside the central city of a metropolitan statistical area (MSA) had a higher prevalence of IBD (1.4%) than did adults living in the central or principal city of an MSA (1.0%). Individuals born in the U.S. were more likely to have been diagnosed with IBD (1.4%) than those who were born elsewhere (0.8%). http://www.medpagetoday.com/Gastroenterology/InflammatoryBowelDisease/61062?xid=nl_mpt_DHE_2016-10-28&eun=g721819d0r&pos=0
