Therefore, we first examined BPR of appropriate\u2010for\u2010dates (AFD) infants in each gestational week in preterm deliveries. We then compared it with that in a group of light\u2010for\u2010dates (LFD) infants born from mothers with and without pregnancy\u2010induced hypertension (PIH).<\/jats:p><jats:p><jats:bold>Material and Methods:\u2002<\/jats:bold> Placentas of a singleton pregnancy with 373 AFD and 110 LFD infants delivered from 22 to 36\u2003weeks of gestation in our hospital during the period between September 2000 and December 2008 were included. We examined the placental weight and BPR of each gestational week in AFD and LFD groups. And the mean BPR and placental weight in the three groups (AFD: LFD with PIH: LFD without PIH) were compared according to gestational periods.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> The placental weight and BPR were significantly correlated to the gestational week both in AFD and LFD groups. We found that although the mean BPR in LFD\u2010PIH(\u2212) group was significantly lower than those both in AFD group and in LFD\u2010PIH(+) group in 22\u201329\u2003weeks, the mean BPR in 30\u201336\u2003weeks was not statistically different among these three groups.<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> Our result in the AFD group may be useful as one of the standards of BPR changes throughout gestation in a Japanese population for future studies. We believe that BPR may be a clinically useful indicator which reflects pathophysiology of FGR.<\/jats:p>","DOI":"10.1111\/j.1447-0756.2011.01641.x","type":"journal-article","created":{"date-parts":[[2011,9,15]],"date-time":"2011-09-15T14:14:51Z","timestamp":1316096091000},"page":"122-129","source":"Crossref","is-referenced-by-count":4,"title":["Birthweight placental weight ratio of appropriate\u2010for\u2010dates and light\u2010for\u2010dates infants in preterm delivery"],"prefix":"10.1111","volume":"38","author":[{"given":"Shinya","family":"Imada","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kimiyo","family":"Takagi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiko","family":"Kikuchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaori","family":"Ishikawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shunsuke","family":"Tamaru","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsuguhiro","family":"Horikoshi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshifumi","family":"Ogiso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,9,15]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.2007.01327.x"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-3782(02)00118-4"},{"key":"e_1_2_5_4_2","first-page":"353","article-title":"Birthweight and placental weight, Thailand 1982\u20131983","volume":"69","author":"Nondasuta A","year":"1986","journal-title":"J Med Assoc Thai"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2009.06.003"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(86)91340-1"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1152\/ajpregu.00340.2004"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/71.5.1344s"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1053\/plac.1999.0432"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwp182"},{"key":"e_1_2_5_11_2","first-page":"103","volume-title":"Pathology of the Placenta (in Japanese)","author":"Nakayama M","year":"2002"},{"key":"e_1_2_5_12_2","first-page":"624","article-title":"Birth size standards by gestational age for Japanese neonates","volume":"34","author":"Ogawa Y","year":"1998","journal-title":"Acta Neonatologica Japonica"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1053\/plac.2001.0757"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1159\/000129671"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.placenta.2009.09.008"},{"key":"e_1_2_5_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2005.10.813"},{"key":"e_1_2_5_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0895-7061(01)02086-6"},{"key":"e_1_2_5_18_2","doi-asserted-by":"publisher","DOI":"10.1080\/00016340802056178"}],"container-title":["Journal of Obstetrics and Gynaecology Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1447-0756.2011.01641.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1447-0756.2011.01641.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,9,23]],"date-time":"2024-09-23T00:43:48Z","timestamp":1727052228000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.1111\/j.1447-0756.2011.01641.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,9,15]]},"references-count":17,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2012,1]]}},"alternative-id":["10.1111\/j.1447-0756.2011.01641.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1447-0756.2011.01641.x","archive":["Portico"],"relation":{},"ISSN":["1341-8076","1447-0756"],"issn-type":[{"type":"print","value":"1341-8076"},{"type":"electronic","value":"1447-0756"}],"subject":[],"published":{"date-parts":[[2011,9,15]]}}}
