Logistic regression was used to evaluate the association between antenatal variables and fetal growth retardation and to test for interaction.<\/jats:p><jats:p><jats:bold>Results.\u2002<\/jats:bold> In logistic models, increasing maternal age [odds ratio (OR)\u20031.06, 95% confidence interval\u2003(CI) 1.01\u20131.11], nulliparity (OR\u20032.2, 95%\u2003CI 1.37\u20133.5), smoking during pregnancy (OR\u20032.56, 95%\u2003CI 1.56\u20134.22), preeclampsia (OR\u200327.5, 95%\u2003CI 15.1\u201349.9), first\u2010trimester hemorrhage (OR\u20032.25, 95%\u2003CI 1.32\u20133.82) and low (&lt;\u20030.2\u2003kg\/week) weight gain in pregnancy (OR\u20033.48, 95%\u2003CI 1.71\u20133.05) were significantly associated with an increased risk of fetal growth restriction complicated by abnormal Doppler studies. These risk factors were also significantly correlated with the occurrence of absent\/reversed end\u2010diastolic blood flow in the umbilical artery. Maternal smoking during pregnancy interacted negatively with preeclampsia but positively with a low weight gain in pregnancy.<\/jats:p><jats:p><jats:bold>Conclusions.\u2002<\/jats:bold> The results of this study have shown that antenatal risk factors for intrauterine growth retardation (IUGR) complicated by abnormal Doppler studies are similar to those associated with the birth of a small\u2010for\u2010gestational\u2010age infant. Preeclampsia, maternal smoking and low weight gain in pregnancy play a significant causal role in the origin of fetal growth restriction associated with abnormal uteroplacental blood flow.<\/jats:p>","DOI":"10.1111\/j.0001-6349.2004.00295.x","type":"journal-article","created":{"date-parts":[[2004,4,1]],"date-time":"2004-04-01T14:32:02Z","timestamp":1080829922000},"page":"431-435","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Interaction between risk factors for fetal growth retardation associated with abnormal umbilical artery Doppler studies"],"prefix":"10.1111","volume":"83","author":[{"given":"Arsenio","family":"Spinillo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carola","family":"Bergante","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Gardella","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberta","family":"Mainini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Montanari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,4]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1097\/00003081-199203000-00015","article-title":"Intrauterine growth retardation.
