Among women who did not have a second\u2010trimester ultrasound examination, labor was induced for presumed post\u2010term pregnancy in 4.0% versus 1.6% of pregnancies in the screening group (p = 0.007). In the group with second\u2010trimester ultrasound scanning other than screening, the frequency was 3.2%. Of women with spontaneous labor or who were induced for presumed post\u2010term pregnancy, 3.8% in a screening group and 8.0% in a group with other second\u2010trimester ultrasound examination were post\u2010term according to BPD measurements (<jats:italic>p<\/jats:italic> = 0.0003).<\/jats:p><jats:p>In the screening group, 6.2% of liveborn singletons were small for gestational age(less than the 10th percentile) compared with 8.5% in the non\u2010screening group (p&lt;0.05).<\/jats:p><jats:p>A subset of 365 screened women with optimal menstrual history had spontaneous labor or were induced for presumed post\u2010term pregnancy. According to menstrual history and ultrasound examination, 7.4% and 3.8% of these were post\u2010term, respectively (p = 0.04).<\/jats:p><jats:p>It is concluded that the main value of screening lies in a more accurate dating of pregnancy, even when menstrual history is optimal, with a lower incidence of induced labor for believed post\u2010term pregnancies. In addition, there may be an improvement in the obstetric management of pregnancy, reflected in our study as a lower incidence of small for gestational age infants.<\/jats:p>","DOI":"10.3109\/00016349009028700","type":"journal-article","created":{"date-parts":[[2007,11,13]],"date-time":"2007-11-13T19:07:41Z","timestamp":1194980861000},"page":"581-588","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["One\u2010Stage Ultrasound Screening in Pregnancy: An evaluation"],"prefix":"10.1111","volume":"69","author":[{"given":"Svein","family":"Rasmussen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Knut","family":"Dalaker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lillian Nordb\u00f8","family":"Berge","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Randi","family":"Lundgren","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kjell","family":"L\u00f8vslett","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,1,7]]},"reference":[{"key":"e_1_2_1_2_1","volume-title":"Diagnostic ultrasound in pregnancyxon\u2010sensus statement","author":"National Institutes of Health consensus development conference","year":"1984"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1017\/S026646230000129X"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1977.tb12550.x"},{"key":"e_1_2_1_5_1","first-page":"1088","article-title":"Percentiles of birth weight and crown\u2010heel length in relation to gestational period for single live births","volume":"100","author":"Bjerkedal T.","year":"1980","journal-title":"Tidsskr Nor Laegeforen"},{"key":"e_1_2_1_6_1","first-page":"747","article-title":"Routine or selective ultrasound examinations in early pregnancy","volume":"69","author":"Belfrage P.","year":"1987","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016347809162696"},{"key":"e_1_2_1_8_1","first-page":"613","article-title":"Routine ultra\u2010sound screening for the prediction of gestational age","volume":"65","author":"Campbell S.","year":"1985","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(84)91834-8"},{"key":"e_1_2_1_10_1","first-page":"575","article-title":"Effects of routine one\u2010stage ultrasound screening in pregnancy: A randomised controlled trial","author":"Waldenstr\u00f6m U.","year":"1988","journal-title":"Lancet"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(84)90492-6"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1982.tb05074.x"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.289.6453.1179"},{"key":"e_1_2_1_14_1","first-page":"136","article-title":"Bestemmelse av f0dselster\u2010min etter seponering av p\u2010pille","volume":"108","author":"Sviggum O.","year":"1988","journal-title":"Tidsskr Nor Liege fore n"},{"key":"e_1_2_1_15_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016349809004289"},{"key":"e_1_2_1_16_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016348509155161"},{"key":"e_1_2_1_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003081-198406000-00008"}],"container-title":["Acta Obstetricia et Gynecologica Scandinavica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.3109%2F00016349009028700","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.3109\/00016349009028700","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,31]],"date-time":"2023-08-31T09:02:21Z","timestamp":1693472541000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.3109\/00016349009028700"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1990,1]]},"references-count":16,"journal-issue":{"issue":"7-8","published-print":{"date-parts":[[1990,1]]}},"alternative-id":["10.3109\/00016349009028700"],"URL":"https:\/\/doi.org\/10.3109\/00016349009028700","archive":["Portico"],"relation":{},"ISSN":["0001-6349","1600-0412"],"issn-type":[{"value":"0001-6349","type":"print"},{"value":"1600-0412","type":"electronic"}],"subject":[],"published":{"date-parts":[[1990,1]]},"assertion":[{"value":"2011-01-07","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
