For this study, we included women with cephalic singletons and planned vaginal delivery from 24 to 34 weeks\u2019 gestation between 2006 and 2016. The main exposure was the mode of delivery (spontaneous vaginal delivery (SVD), OVD, and cesarean delivery (CS) during labor). The primary outcome was non-optimal neurodevelopmental outcome at the corrected age of 2 years assessed by a physical examination, a neuropsychological test, and\/or a parental questionnaire. Secondary outcomes were survival at discharge and survival at discharge without morbidity. We used the multivariate logistic regression and propensity score methods to compare outcomes associated with OVD. The study included 1934 infants born preterm: 1384 (71.6%) with SVD, 87 (4.5%) with OVD, and 463 (23.9%) with CS. Neonates with SVD, OVD, and CS did not differ in survival (97.0%, 97.7%, and 97.8%, respectively; p = 0.79) or in survival without morbidity (82.8%, 86.2%, and 82.7%, respectively; p = 0.71). In survived infants, 1578 (81.6%) were evaluated at age two: 279 (17.7%) were considered to have a non-optimal neurodevelopmental outcome (18.3% after SVD, 18.0% after OVD, and 15.9% after CS; p = 0.57). Propensity score analysis showed that OVD was not associated with non-optimal neurocognitive development at age two, with an adjusted odds ratio (aOR) of 0.86 and a 95% confidence interval (95% CI) of 0.47\u20131.69, compared with SVD; and an aOR of 0.76 and a 95% CI of 0.31\u20131.8, compared with CS. Operative vaginal delivery was not associated with non-optimal neurocognitive development at 2 years of corrected age for preterm singletons.<\/jats:p>","DOI":"10.3390\/jcm12154970","type":"journal-article","created":{"date-parts":[[2023,7,28]],"date-time":"2023-07-28T07:58:52Z","timestamp":1690531132000},"page":"4970","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Neurodevelopmental Outcome at Corrected Age of 2 Years among Children Born Preterm with Operative Vaginal Delivery: A Population-Based Study (LIFT Cohort)"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2549-353X","authenticated-orcid":false,"given":"Guillaume","family":"Ducarme","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Centre Hospitalier Departemental, 85000 La Roche-sur-Yon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-4034-5908","authenticated-orcid":false,"given":"Victoria","family":"Fosse","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Centre Hospitalier Departemental, 85000 La Roche-sur-Yon, France"},{"name":"Department of Obstetrics and Gynecology, Centre Hospitalier Universitaire de Nantes, 44000 Nantes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9rie","family":"Rouger","sequence":"additional","affiliation":[{"name":"Loire Infant Follow-Up Team (LIFT) Network, 44000 Nantes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norbert","family":"Winer","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Centre Hospitalier Universitaire de Nantes, 44000 Nantes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cyril","family":"Flamant","sequence":"additional","affiliation":[{"name":"Department of Neonatalogy, Centre Hospitalier Universitaire de Nantes, 44000 Nantes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marion","family":"Olivier","sequence":"additional","affiliation":[{"name":"Loire Infant Follow-Up Team (LIFT) Network, 44000 Nantes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e37","DOI":"10.1016\/S2214-109X(18)30451-0","article-title":"Global, regional, and national estimates of levels of preterm birth in 2014: A systematic review and modelling analysis","volume":"7","author":"Chawanpaiboon","year":"2019","journal-title":"Lancet Glob.
