To correlate fetal growth acceleration with factors that might influence fetal growth.<\/jats:p>\n               <jats:p>RESEARCH DESIGN AND METHODS\u2014This retrospective study involved all pregestational diabetic pregnancies delivered at a tertiary obstetric hospital in Australia between 1 January 1994 and 31 December 1999. Pregnancies with major congenital fetal anomalies, multiple pregnancies, small-for-gestational-age pregnancies (&amp;lt;10th centile), and those that were terminated before 20 weeks were excluded. In this cohort, pregnancies delivered at term had at least four ultrasound scans performed. The first scans were performed before 14 weeks of gestation and were regarded as dating scans. Abdominal circumference measurements were retrieved from the ultrasound reports. The z-scores for abdominal circumferences, according to the gestational age, were calculated. The gestations when the ultrasound scans were performed were stratified at four weekly intervals beginning at 18 weeks and continuing through the rest of the study. Majority of these diabetic pregnancies had ultrasound scans performed at 18, 28, 32, and 36 weeks. The abdominal circumference z-scores for pregnancies with large-for-gestational-age (LGA) babies (&amp;gt;90th centile for gestation) were compared with babies with normal birth weights.<\/jats:p>\n               <jats:p>RESULTS\u2014A total of 101 diabetic pregnancies were included. Diabetic mothers, who had LGA babies, had significantly higher prepregnancy body weight and BMI (P &amp;lt; 0.05). There were no differences in maternal age or parity among the two groups. There were also no differences in the first-, second-, and third-trimester HbA1c levels between the two groups. The abdominal circumference z-scores were significantly higher for LGA babies from 18 weeks and thereafter. The differences increased progressively as the gestation advanced. Maximum difference was noted in the third trimester (30\u201338 weeks).<\/jats:p>\n               <jats:p>CONCLUSIONS\u2014Fetal growth acceleration in LGA fetuses of diabetic mothers starts in the second trimester, from as early as 18 weeks. In this study, glucose control did not appear to have a direct effect on the incidence of LGA babies, and such observation might result from the effects of other confounding factors.<\/jats:p>","DOI":"10.2337\/diacare.25.10.1681","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T22:51:27Z","timestamp":1173135087000},"page":"1681-1684","update-policy":"https:\/\/doi.org\/10.2337\/ada-journal-policies","source":"Crossref","is-referenced-by-count":49,"title":["Fetal Growth Spurt and Pregestational Diabetic Pregnancy"],"prefix":"10.2337","volume":"25","author":[{"given":"Shell Fean","family":"Wong","sequence":"first","affiliation":[{"name":"Department of Maternal Fetal Medicine, Mater Mothers\u2019 Hospital, South Brisbane, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fung Yee","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Maternal Fetal Medicine, Mater Mothers\u2019 Hospital, South Brisbane, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeremy J.N.","family":"Oats","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Mater Mothers\u2019 Hospital, South Brisbane, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David H.","family":"McIntyre","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Mater Mothers\u2019 Hospital, South Brisbane, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1167","reference":[{"key":"2022031217111249300_R1","doi-asserted-by":"crossref","unstructured":"Fraser R: Diabetic control in pregnancy and intrauterine growth of the fetus.
