The incidence of gastroschisis is increasing worldwide, but the causes and risk factors of this increase are not well elucidated.1 This study examines the incidence of gastroschisis in California over time and by county.

This was a population analysis using data from the Linked Birth Database from the California Office of Statewide Health Planning and Development from 1995 to 2012, which includes information on all births in California. Patients with gastroschisis were identified by an International Classification of Diseases-Ninth Edition (ICD-9) procedure code for gastroschisis repair (54.71), ICD-9 diagnosis code for gastroschisis (756.73, available since 2009), or birth certificate designation for gastroschisis (available since 2006). We performed the study from July to December 2017. This study was approved by the UC Davis Institutional Review Board and the California Committee for the Protection of Human Subjects, which waived informed patient consent for deidentified data.
