Lund, Agnethe; Ebbing, Cathrine; Rasmussen, Svein; Kiserud, Torvid; Hanson, Mark; Kessler, Jørg (Peer reviewed; Journal article, 2019-03-13)Background: Pregestational diabetes is associated with fetal macrosomia, and umbilical perfusion of the fetal liver has a role in regulating fetal growth. We therefore hypothesized that pregestational diabetes alters fetal ... -

Fetuses determined by ultrasound biometry to be small in early pregnancy, have an increased risk of premature birth. We speculate that the ... -

Paternal and maternal birthweight and offspring risk of macrosomia at term gestations: A nationwide population study
Rasmussen, Svein; Carlsen, Ellen Øen; Linde, Lorentz; Morken, Nils-Halvdan; Håberg, Siri Eldevik; Ebbing, Cathrine (Journal article; Peer reviewed, 2023)Background There is a paucity of data on whether parents' macrosomia (birthweight ≥4500 g) status influences the risk of macrosomia in the offspring. The role of maternal overweight in the generational effect of macrosomia ... -
Pre-gestational diabetes: Maternal body mass index and gestational weight gain are associated with augmented umbilical venous flow, fetal liver perfusion, and thus birthweight
Lund, Agnethe; Ebbing, Cathrine; Rasmussen, Svein; Qvigstad, Elisabeth; Kiserud, Torvid; Kessler, Jørg (Journal article; Peer reviewed, 2021)Objectives To assess how maternal body mass index and gestational weight gain are related to on fetal venous liver flow and birthweight in pregnancies with pre-gestational diabetes mellitus. Methods In a longitudinal ... -
Predicting preeclampsia from a history of preterm birth
Rasmussen, Svein; Ebbing, Cathrine; Irgens, Lorentz M. (Peer reviewed; Journal article, 2017-07-24)Objective: To assess whether women with a history of preterm birth, independent on the presence of prelabour rupture of the membranes (PROM) and growth deviation of the newborn, are more likely to develop preeclampsia with ... -

L.; Rasmussen, Svein; Kiserud, Torvid (Peer reviewed; Journal article, 2016-08)Objective: To test whether adding conditional growth centiles to size centiles of estimated fetal weight (EFW) improves prediction of adverse perinatal outcome in pregnancies with or at risk of having a small-for-gestational-age ... -
