Live births (LB), stillbirths (SB), and termination of pregnancy for fetal anomaly (TOPFA) diagnosed with OA were selected from the Congenital Anomalies population-based Registry of VR (RPAC-CV). The prevalence of OA per 10,000 births with 95% confidence interval was calculated, and socio-demographic and clinical variables were analyzed. A total of 146 OA cases were identified. The overall prevalence was 2.4\/10,000 births, and prevalence by type of pregnancy ending was 2.3 in LB and 0.03 in both SB and TOPFA. A mortality rate of 0.03\/1000 LB was observed. A relationship was found between case mortality and birth weight (p-value &lt; 0.05). OA was primarily diagnosed at birth (58.2%) and 71.2% of the cases were associated with another congenital anomaly, mainly congenital heart defects. Significant variations in the prevalence of OA in the VR were detected throughout the study period. In conclusion, a lower prevalence in SB and TOPFA was identified compared to EUROCAT data. As several studies have identified, an association between OA cases and birth weight was found.<\/jats:p>","DOI":"10.3390\/ijerph20054042","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T03:01:01Z","timestamp":1677207661000},"page":"4042","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Oesophageal Atresia: Prevalence in the Valencian Region (Spain) and Associated Anomalies"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1301-5634","authenticated-orcid":false,"given":"Adriana","family":"Agurto-Ram\u00edrez","sequence":"first","affiliation":[{"name":"Service of Preventive Medicine, Valencia General University Hospital Consortium, 46014 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9094-7107","authenticated-orcid":false,"given":"Laura","family":"Garc\u00eda-Villodre","sequence":"additional","affiliation":[{"name":"Rare Diseases Joint Research Unit, Foundation for the Promotion of Health and Biomedical Research in the Valencian Region-Valencia University (FISABIO-UVEG), 46020 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana","family":"Ruiz-Palacio","sequence":"additional","affiliation":[{"name":"Rare Diseases Joint Research Unit, Foundation for the Promotion of Health and Biomedical Research in the Valencian Region-Valencia University (FISABIO-UVEG), 46020 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2414-0510","authenticated-orcid":false,"given":"Berta","family":"Arribas-D\u00edaz","sequence":"additional","affiliation":[{"name":"Rare Diseases Joint Research Unit, Foundation for the Promotion of Health and Biomedical Research in the Valencian Region-Valencia University (FISABIO-UVEG), 46020 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5272-265X","authenticated-orcid":false,"given":"Laia","family":"Barrachina-Bonet","sequence":"additional","affiliation":[{"name":"Rare Diseases Joint Research Unit, Foundation for the Promotion of Health and Biomedical Research in the Valencian Region-Valencia University (FISABIO-UVEG), 46020 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2952-564X","authenticated-orcid":false,"given":"Luc\u00eda","family":"P\u00e1ramo-Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Rare Diseases Joint Research Unit, Foundation for the Promotion of Health and Biomedical Research in the Valencian Region-Valencia University (FISABIO-UVEG), 46020 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7279-432X","authenticated-orcid":false,"given":"\u00d3scar","family":"Zurriaga","sequence":"additional","affiliation":[{"name":"Rare Diseases Joint Research Unit, Foundation for the Promotion of Health and Biomedical Research in the Valencian Region-Valencia University (FISABIO-UVEG), 46020 Valencia, Spain"},{"name":"Public Health Regional Health Administration, Generalitat Valenciana, 46020 Valencia, Spain"},{"name":"Department of Preventive Medicine and Public Health, Food Sciences, Toxicology and Legal Medicine, University of Valencia, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4858-6456","authenticated-orcid":false,"given":"Clara","family":"Cavero-Carbonell","sequence":"additional","affiliation":[{"name":"Rare Diseases Joint Research Unit, Foundation for the Promotion of Health and Biomedical Research in the Valencian Region-Valencia University (FISABIO-UVEG), 46020 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,24]]},"reference":[{"key":"ref_1","unstructured":"Pr Lewis, S.
