DefinitionGastroschisis is a birth defect of the abdominal (belly) wall. The baby's intestines stick outside of the baby's body, through a hole beside the belly button. The hole can be small or large and sometimes other organs, such as the stomach and liver, can also stick outside of the baby's body. Prevalence of gastroschisis is the number of live-born infants with gasthroschisis per 10,000 live-born infants. (Live-born infants are the infants born with any evidence of life).
NumeratorNumber of live-born infants with gastroschisis.
DenominatorNumber of live-born infants.
Data Interpretation IssuesIn January 2000, birth defects became a reportable condition in New Mexico; however, birth defects were collected prior to this date. The first year of consistent data is 1998. For gastroschisis data, the most recent year of analyzed data is 2011.
Data are collected on live births occurring in-state to NM residents. Therefore, live births that occur in NM among out-of-state residents are excluded.
Case finding/identification occurs through review of birth and death certificates, hospital discharge diagnoses, records from pediatric specialists and prenatal diagnostic providers.
Birth defect cases are ascertained up to age 4; however, the majority of diagnoses are made by age 1.
Why Is This Important?Birth defects pose a significant public health problem. One in 33 babies is born with a structural birth defect in the United States. Birth defects cause one in five deaths among infants less than a year old and lead to $2.6 billion per year in hospital costs alone in the U.S.
Infants with gastroschisis must undergo surgical repair following birth to return the intestines to the abdomen and close the defect. After the repair, infants with gastroschisis can have problems with feeding, digestion of food, and absorption of nutrients.

How Do We Compare With the U.S.?The national prevalence of gastroschisis among births from 2004-2006 is 4.49 per 10,000 births. These data data come from 14 birth defects surveillance programs: Arkansas, Arizona, California [8-county Central Valley], Colorado, Georgia [5-county metropolitan Atlanta], Illinois, Iowa, Kentucky, Massachusetts, North Carolina, Oklahoma, Puerto Rico, Texas, and Utah.

Due to variability in the methods used by state birth defects surveillance systems and differences in populations and risk factors, state prevalence estimates may not be directly comparable with national estimates or those of other states.
