We sought to compare rates of PTB during the pre- and post vaccination COVID periods with pre-pandemic PTB rates, stratified by race and ethnicity.<\/jats:p><jats:p>\n            Study Design\u2003Retrospective cohort comparing all deliveries over 20 weeks at a single tertiary center during \u201cearly\u201d (March 2020\u2013June 2020) versus \u201clate\u201d COVID (March 2021\u2013June 2021), and \u201clate\u201d COVID versus pre-COVID (March to June 2014\u20132019). PTBs &lt;37, &lt;34, and &lt;28 weeks were compared and stratified by race\/ethnicity.<\/jats:p><jats:p>\n            Results\u2003A total of 16,483 deliveries occurred including 2,068 \u201cearly\u201d COVID, 2,115 \u201clate\u201d COVID, and 12,300 pre-COVID. The PTB rate during \u201clate\u201d COVID was lower compared to \u201cearly\u201d COVID (12.1 vs. 14.6%, p\u2009=\u20090.02). Rate of PTB &lt;34 was also lower during \u201clate\u201d COVID (4.4 vs. 5.7%, p\u2009=\u20090.05). PTB &lt;28 did not differ. When controlling for prior PTB, \u201clate\u201d COVID remained associated with a decreased risk of PTB compared to \u201cearly\u201d COVID, adjusted odds ratio (aOR) of 0.82 (95% confidence interval [CI]: 0.68, 0.98). Although there was no difference in PTB among Hispanic individuals when comparing \u201clate\u201d COVID versus pre-COVID, when further subdivided, a small number of Hispanic Puerto Rican individuals had higher odds of PTB\u2009&lt;\u200937 during \u201clate\u201d COVID versus pre-COVID (aOR\u2009=\u20094.29 [95% CI: 1.12, 16.4]). Additionally, White individuals had reduced odds of PTB &lt;37 (aOR\u2009=\u20090.80 [95% CI: 0.65, 0.98]) during \u201clate\u201d COVID versus pre-COVID while the PTB rate was unchanged when comparing \u201clate\u201d COVID versus pre-COVID in all other racial and ethnic groups.<\/jats:p><jats:p>\n            Conclusion\u2003During 2021, PTB rates decreased from rates observed in 2020 at the height of COVID restrictions. Among White birthing individuals, PTB decreased in 2021 compared to pre-COVID rates. This decrease was not observed in Black and Hispanic birthing individuals. These data highlight the continued racially disparate impact of the COVID-19 pandemic on PTB rates.<\/jats:p><jats:p>\n            Key Points\n          <\/jats:p>","DOI":"10.1055\/a-2008-8229","type":"journal-article","created":{"date-parts":[[2023,1,6]],"date-time":"2023-01-06T23:49:56Z","timestamp":1673048996000},"page":"e1288-e1290","source":"Crossref","is-referenced-by-count":2,"special_numbering":"S","title":["Preterm Birth Rates and Racial Disparities during the COVID-19 Pandemic at a Single Institution in the Southeastern United States"],"prefix":"10.1055","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7349-6460","authenticated-orcid":false,"given":"Jennifer J.
