Gestational LD has been associated with adverse pregnancy outcomes; however, the results have been contradictory. The study objective was to examine the effects of gestational LD on obstetrical and neonatal outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Using the Healthcare Cost &amp; Utilization Project National (Nationwide) Inpatient Sample from the United States, we conducted a retrospective cohort study of pregnant patients admitted to the hospital between 2016 and 2019. The exposed group consisted of pregnant patients with gestational LD infection (<jats:italic>International Classification of Diseases, Tenth Revision<\/jats:italic> [<jats:italic>ICD\u201010<\/jats:italic>] code A692x), while the comparison group consisted of pregnant patients without gestational LD. Descriptive statistics and multivariate logistic regression models, adjusted for baseline maternal characteristics, were used to determine the associations between gestational LD and obstetrical and neonatal outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The cohort included 2\u2009943\u2009575 women, 226 of whom were diagnosed with LD during pregnancy. The incidence of LD was 7.67 per 100\u2009000 pregnancy admissions. The incidence of gestational LD was stable over the study period. Pregnant patients with LD were more likely white, older, to have private health insurance, and to belong to a higher income quartile. Gestational LD was associated with an increased risk of placental abruption (adjusted odds ratio [aOR], 3.45 [95% confidence interval (CI), 1.53\u20137.80]) and preterm birth (aOR, 1.58 [95% CI, 1.03\u20132.42]).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Gestational LD is associated with a higher risk of placental abruption and preterm birth. Pregnancies complicated by LD, while associated with a higher risk of certain adverse outcomes, can be followed in most healthcare settings.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ijgo.15380","type":"journal-article","created":{"date-parts":[[2024,1,22]],"date-time":"2024-01-22T06:00:11Z","timestamp":1705903211000},"page":"451-457","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Obstetrical and neonatal outcomes in women with gestational Lyme disease"],"prefix":"10.1002","volume":"166","author":[{"given":"Julien M.","family":"Courville","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Jewish General Hospital McGill University  Montreal Quebec Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicholas","family":"Czuzoj\u2010Shulman","sequence":"additional","affiliation":[{"name":"Center for Clinical Epidemiology and Community Studies Jewish General Hospital  Montreal Quebec Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8962-9555","authenticated-orcid":false,"given":"Andrea R.","family":"Spence","sequence":"additional","affiliation":[{"name":"Center for Clinical Epidemiology and Community Studies Jewish General Hospital  Montreal Quebec Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7001-7153","authenticated-orcid":false,"given":"Haim A.","family":"Abenhaim","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Jewish General Hospital McGill University  Montreal Quebec Canada"},{"name":"Center for Clinical Epidemiology and Community Studies Jewish General Hospital  Montreal Quebec Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,1,21]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0207067"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jogc.2020.01.001"},{"key":"e_1_2_10_4_1","first-page":"333","article-title":"Lyme disease in humans","volume":"42","author":"Radolf JD","year":"2021","journal-title":"Curr Issues Mol Biol"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10096-018-3417-1"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-103-1-67"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1986.03370240064038"},{"key":"e_1_2_10_8_1","first-page":"615","article-title":"Stillbirth following maternal Lyme disease","volume":"87","author":"MacDonald AB","year":"1987","journal-title":"N Y State J Med"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016348709022058"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(93)90088-Z"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm9082364"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-3016.1995.tb00148.x"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.ogx.0000251024.43400.9a"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(99)70277-2"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijid.2009.07.019"},{"key":"e_1_2_10_16_1","unstructured":"Healthcare Cost & Utilization Project.Overview of the National (Nationwide) Inpatient Sample (NIS).
