Increasing Prevalence of Gastroschisis--14 States, 1995-2012

Gastroschisis is a serious congenital defect in which the intestines protrude through an opening in the abdominal wall. Gastroschisis requires surgical repair soon after birth and is associated with an increased risk for medical complications and mortality during infancy. Reports from multiple surveillance systems worldwide have documented increasing prevalence of gastroschisis since the 1980s, particularly among younger mothers; however, since publication of a multistate U.S. report that included data through 2005, it is not known whether prevalence has continued to increase. Data on gastroschisis from 14 population-based state surveillance programs were pooled and analyzed to assess the average annual percent change (AAPC) in prevalence and to compare the prevalence during 2006-2012 with that during 1995-2005, stratified by maternal age and race/ethnicity. The pooled data included approximately 29% of U.S. births for the period 1995-2012. During 1995-2012, gastroschisis prevalence increased in every category of maternal age and race/ethnicity, and the AAPC ranged from 3.1% in non-Hispanic white (white) mothers aged
