Blood flow velocimetry waveforms from both UtAs were obtained and the pulsatility index (PI) measured and recorded. Clinical records were reviewed for pregnancy outcomes. Birth weight was expressed as <jats:italic>z<\/jats:italic>\u2010scores, and the Spearman correlation coefficient (<jats:italic>\u03c1<\/jats:italic>) was used to calculate the relationship between the mean, delta, and lowest UtA PI values and birth weight.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There was no correlation between the mean and delta UtA PI values and birth weight. However, a significant correlation between the lowest UtA PI value and birth weight (<jats:italic>\u03c1<\/jats:italic>\u2009=\u2009\u22120.121; <jats:italic>p<\/jats:italic>\u2009=\u20090.013) was noted.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our study found a clinically significant correlation between the lowest UtA PI value and birth weight in an unselected, low\u2010risk pregnant population. Because fetal growth is a multifactorial process in which placentation is only one of the factors involved, the use of a single parameter such as Doppler velocimetry remote from the delivery to predict birth weight in a low\u2010risk population seems to be less useful than in the high\u2010risk population. \u00a9 2012 John Wiley &amp; Sons, Ltd.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pd.3997","type":"journal-article","created":{"date-parts":[[2012,12,7]],"date-time":"2012-12-07T06:21:22Z","timestamp":1354861282000},"page":"21-24","source":"Crossref","is-referenced-by-count":9,"title":["First\u2010trimester uterine artery Doppler velocimetry in the prediction of birth weight in a low\u2010risk population"],"prefix":"10.1002","volume":"33","author":[{"given":"Andres","family":"Sarmiento","sequence":"first","affiliation":[{"name":"Division of Maternal\u2013Fetal Medicine, Department of Gynecology, Obstetrics, and Human Reproduction Fundaci\u00f3n Santa Fe de Bogota University Hospital, IMAFET Group  Bogota Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandra","family":"Casasbuenas","sequence":"additional","affiliation":[{"name":"Division of Maternal\u2013Fetal Medicine, Department of Gynecology, Obstetrics, and Human Reproduction Fundaci\u00f3n Santa Fe de Bogota University Hospital, IMAFET Group  Bogota Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadiezhda","family":"Rodriguez","sequence":"additional","affiliation":[{"name":"Division of Maternal\u2013Fetal Medicine, Department of Gynecology, Obstetrics, and Human Reproduction Fundaci\u00f3n Santa Fe de Bogota University Hospital, IMAFET Group  Bogota Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana M.","family":"Angarita","sequence":"additional","affiliation":[{"name":"Division of Maternal\u2013Fetal Medicine, Department of Gynecology, Obstetrics, and Human Reproduction Fundaci\u00f3n Santa Fe de Bogota University Hospital, IMAFET Group  Bogota Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piedad","family":"Sarmiento","sequence":"additional","affiliation":[{"name":"Division of Maternal\u2013Fetal Medicine, Department of Gynecology, Obstetrics, and Human Reproduction Fundaci\u00f3n Santa Fe de Bogota University Hospital, IMAFET Group  Bogota Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Waldo","family":"Sepulveda","sequence":"additional","affiliation":[{"name":"Fetal Medicine Center Fetal Medicine Interest Group GIMEF  Santiago Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,12,7]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0143-4004(80)80012-9"},{"key":"e_1_2_6_3_1","volume-title":"Major Problems in Pathology","author":"Fox H","year":"2007"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.0960-7692.2001.00572.x"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.6452"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(83)91970-0"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1993.tb15139.x"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.0960-7692.2001.00594.x"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/pd.2440"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1998.tb10128.x"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.231"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(98)70030-4"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(97)11280-6"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/pd.2637"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/pd.2642"},{"key":"e_1_2_6_16_1","unstructured":"The Fetal Medicine Foundation.
