Incorporating placental thickness and fetal biometrics in estimating GA may improve the accuracy of fetal age estimation. The aim of this study was to examine the relationship between placental thickness and GA in pregnant women referred to Al\u2010Zahra Hospital's prenatal and emergency clinic in Rasht, Iran.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This cross\u2010sectional study was conducted on pregnant women referred to Al\u2010Zahra Clinic for prenatal care over a 6\u2010month period. After obtaining informed consent, data were collected on the date of the first day of the last safe menstruation, average body mass index, and medical and surgical history. Placental thickness was estimated using ultrasound and various clinical information was recorded. The data were then analyzed using Pearson correlation analysis in SPSS software version 21.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The results showed a significant correlation between GA and placental thickness (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.0001,\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u20090.729). Placental thickness increased with increasing GA. There was also a significant relationship between placental thickness and placental location (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.009,\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u20090.14). In the posterior position, placental thickness increased by 14% or 0.14. The placental thickness in the posterior position (29.49\u2009\u00b1\u20090.75) was greater than the anterior position (26.94\u2009\u00b1\u200910.72).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The findings of this study suggest that there is a significant increase in placental thickness with increasing GA during the first and second trimesters. Additionally, placental thickness significantly increased in the posterior placental position, as well as in women with high BMI. Therefore, it is recommended that measuring placental thickness should be routine during obstetric ultrasounds.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/hsr2.1228","type":"journal-article","created":{"date-parts":[[2023,4,28]],"date-time":"2023-04-28T02:19:04Z","timestamp":1682648344000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The relationship between placental thickness and gestational age in pregnant women: A cross\u2010sectional study"],"prefix":"10.1002","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7815-3769","authenticated-orcid":false,"given":"Seyedeh H.","family":"Sharami","sequence":"first","affiliation":[{"name":"Department of Obstetrics &amp; Gynecology, Reproductive Health Research Center, Al\u2010zahra Hospital, School of Medicine Guilan University of Medical Sciences Rasht Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0430-6993","authenticated-orcid":false,"given":"Forozan","family":"Milani","sequence":"additional","affiliation":[{"name":"Department of Obstetrics &amp; Gynecology, Reproductive Health Research Center, Al\u2010zahra Hospital, School of Medicine Guilan University of Medical Sciences Rasht Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2470-0434","authenticated-orcid":false,"given":"Sima","family":"Fallah Arzpeyma","sequence":"additional","affiliation":[{"name":"Department of Radiology, Poursina Hospital, School of Medicine Guilan University of Medical Sciences Rasht Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2177-0832","authenticated-orcid":false,"given":"Seyedeh F.","family":"Dalil Heirati","sequence":"additional","affiliation":[{"name":"Reproductive Health Research Center, Al\u2010zahra Hospital Guilan University of Medical Sciences Rasht Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6339-8771","authenticated-orcid":false,"given":"Zahra","family":"Pourhabibi","sequence":"additional","affiliation":[{"name":"Vice\u2010Chancellorship of Research and Technology Guilan University of Medical Science Rasht Zahra Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,4,27]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.contraception.2014.07.004"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12884-016-1192-5"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.20272"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.1870110705"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.2981\/wlb.00771"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.4103\/amhsr.amhsr_457_15"},{"issue":"1","key":"e_1_2_11_8_1","doi-asserted-by":"crossref","first-page":"17","DOI":"10.4103\/JMU.JMU_127_18","article-title":"Fetal gestational age determination using ultrasound placental thickness","volume":"28","author":"Azagidi AS","year":"2020","journal-title":"J Med Ultrasound"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2022.48685"},{"key":"e_1_2_11_10_1","unstructured":"Nnithya Priya DarshiniK.
