The aim of this study is to determine the effect of interpregnancy interval (IPI) on the incidence of placenta previa and placenta accreta spectrum disorders in women with a previous cesarean section. Methods. A prospective cohort three-center study involving parturients who had previous cesarean section was conducted. Participants were included if pregnancy has lasted up to 34\u2009weeks. Parturients with co-existing uterine fibroids, multiple gestations, premature rupture of membranes, and those with prior postcesarean delivery wound infection were excluded. The eligible women recruited were distributed into two groups, namely, short (&lt;18\u2009months) and normal (18\u201336\u2009months) IPI. The outcome measures were incidences of placenta previa and placenta accreta spectrum disorder and factors associated with the occurrence of placenta previa. A univariate analysis was performed using the chi-square test or Mann\u2013Whitney U test, wherever appropriate, to examine the significance of the differences in clinical variables. Results. A total of 248 women met the inclusion criteria. The incidence of placenta previa by ultrasound was 8.9% and 4.0% for short and normal IPI (odds ratios\u2009=\u20092.32; 95% confidence intervals\u2009=\u20090.78\u20136.88; <jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>p<\/a:mi>\n                        <a:mo>=<\/a:mo>\n                        <a:mn>0.13<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>), respectively. The incidence of placenta accreta spectrum disorder was 1.6% and 0.8% for short and normal IPI (odds ratios\u2009=\u20092.02; 95% confidence intervals\u2009=\u20090.18\u201322.13; <jats:inline-formula>\n                     <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>p<\/c:mi>\n                        <c:mo>=<\/c:mo>\n                        <c:mn>0.57<\/c:mn>\n                     <\/c:math>\n                  <\/jats:inline-formula>), respectively. The only observed significant difference between the clinical variables and placenta previa is the number of cesarean sections (<jats:inline-formula>\n                     <e:math xmlns:e=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\">\n                        <e:mi>p<\/e:mi>\n                        <e:mo>=<\/e:mo>\n                        <e:mn>0.02<\/e:mn>\n                     <\/e:math>\n                  <\/jats:inline-formula>) in women with short IPI. Conclusion. A short interpregnancy interval does not significantly affect the incidence of placenta previa and placenta accreta spectrum disorder following a cesarean section. There is a need for further study with large numbers to corroborate these findings in low- and middle-income settings.<\/jats:p>","DOI":"10.1155\/2022\/8028639","type":"journal-article","created":{"date-parts":[[2022,8,3]],"date-time":"2022-08-03T23:35:17Z","timestamp":1659569717000},"page":"1-9","source":"Crossref","is-referenced-by-count":2,"title":["Comparison of Placenta Previa and Placenta Accreta Spectrum Disorder Following Previous Cesarean Section between Women with a Short and Normal Interpregnancy Interval"],"prefix":"10.1155","volume":"2022","author":[{"given":"Uchenna Anthony","family":"Umeh","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, College of Medicine, University of Nigeria, Enugu Campus, Enugu, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0390-2152","authenticated-orcid":true,"given":"George Uchenna","family":"Eleje","sequence":"additional","affiliation":[{"name":"Effective Care Research Unit, Department of Obstetrics and Gynecology, Faculty of Medicine, Nnamdi Azikiwe University, Awka, Nigeria"},{"name":"Department of Obstetrics and Gynecology, Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justus Uchenna","family":"Onuh","sequence":"additional","affiliation":[{"name":"Department of Psychology Medicine, Nnamdi Azikiwe University, Awka, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ogochukwu Theophilus","family":"Nwankwo","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, College of Medicine, University of Nigeria, Enugu Campus, Enugu, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ijeoma Victoria","family":"Ezeome","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, College of Medicine, University of Nigeria, Enugu Campus, Enugu, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leonard Ogbonna","family":"Ajah","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, College of Medicine, University of Nigeria, Enugu Campus, Enugu, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ngozi Regina","family":"Dim","sequence":"additional","affiliation":[{"name":"Department of Radiation Medicine, College of Medicine, University of Nigeria, Enugu Campus, Enugu, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samuel Nnamdi","family":"Obi","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, College of Medicine, University of Nigeria, Enugu Campus, Enugu, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3730-621X","authenticated-orcid":true,"given":"Chidebe Christian","family":"Anikwe","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2515-8464","authenticated-orcid":true,"given":"Joseph Ifeanyichukwu","family":"Ikechebelu","sequence":"additional","affiliation":[{"name":"Effective Care Research Unit, Department of Obstetrics and Gynecology, Faculty of Medicine, Nnamdi Azikiwe University, Awka, Nigeria"},{"name":"Department of Obstetrics and Gynecology, Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"doi-asserted-by":"publisher","key":"1","DOI":"10.1097\/01.aog.0000171118.79529.a3"},{"doi-asserted-by":"publisher","key":"2","DOI":"10.1016\/s0301-2115(02)00077-5"},{"doi-asserted-by":"publisher","key":"3","DOI":"10.1097\/aog.0b013e3182955e58"},{"doi-asserted-by":"publisher","key":"4","DOI":"10.1136\/bmj.g4333"},{"doi-asserted-by":"publisher","key":"5","DOI":"10.1016\/s0029-7844(99)00583-9"},{"doi-asserted-by":"publisher","key":"6","DOI":"10.1056\/nejm199902253400801"},{"doi-asserted-by":"publisher","key":"7","DOI":"10.1001\/jamainternmed.2018.4696"},{"doi-asserted-by":"publisher","key":"8","DOI":"10.1186\/s12884-016-0929-5"},{"doi-asserted-by":"publisher","key":"9","DOI":"10.1097\/ogx.0b013e31826b2c3e"},{"volume-title":"Report of a WHO Technical Consultation on Birth Spacing","year":"2005","author":"World Health Organization","key":"10"},{"doi-asserted-by":"publisher","key":"11","DOI":"10.1016\/j.ajog.2006.05.055"},{"issue":"1","key":"12","first-page":"36","article-title":"Inter-pregnancy interval (IPI): what is the ideal?","volume":"2","author":"G.
