Female adiposity and time-to-pregnancy: a multiethnic prospective cohort.

Hum Reprod 2018 Nov;33(11):2141-2149

Department of Reproductive Medicine, KK Women's and Children's Hospital, Singapore, Singapore.

Study Question: Are higher overall and central adiposity associated with reduced fecundability, measured by time-to-pregnancy (TTP), in Asian women?

Summary Answer: Higher overall adiposity, but not central adiposity, was associated with longer TTP in Asian women.

What Is Known Already: High body mass index (BMI) has been associated with a longer TTP, although the associations of body composition and distribution with TTP are less clear. There are no previous studies of TTP in Asian women, who have a relatively higher percentage of body fat and abdominal fat at relatively lower BMI. Read More

Advances in assessing body composition during pregnancy.

Eur J Clin Nutr 2018 05 2;72(5):645-656. Epub 2018 May 2.

Reproductive Endocrinology and Women's Health, Pennington Biomedical Research Center, 6400 Perkins Road, Baton Rouge, LA, 70808, USA.

The prevalence of excess gestational weight gain is increasing worldwide and is associated with pregnancy complications, including gestational diabetes mellitus, pre-eclampsia, preterm birth, macrosomia, and development of obesity in offspring. Whereas gestational weight gain positively correlates with the gain in fat mass (FM), fat-free mass (FFM) gain is relatively consistent across pregnancies. Commonly used methods to assess body composition include anthropometry, densitometry (air displacement plethysmography, underwater weighing), and hydrometry (isotope dilution, bioimpedance analysis).

The accuracy of ultrasound estimation of fetal weight in comparison to birth weight: A systematic review.

Ultrasound 2018 Feb 7;26(1):32-41. Epub 2018 Feb 7.

2University of Leeds, Leeds, UK.

Ultrasound estimation of fetal weight is a highly influential factor in antenatal management, guiding both the timing and mode of delivery of a pregnancy. Although substantial research has investigated the most accurate ultrasound formula for calculating estimated fetal weight, current evidence indicates significant error levels. The aim of this systematic review was to identify the most accurate method, whilst identifying sources of inaccuracy in order to facilitate recommendations for future practice. Read More

Fetal growth velocity and body proportion in the assessment of growth.

Am J Obstet Gynecol 2018 Feb;218(2S):S700-S711.e1

Division of Maternal-Fetal Medicine, Department of Obstetrics and Gynecology, Sunnybrook Health Sciences Center, University of Toronto, Toronto, Ontario, Canada. Electronic address:

Fetal growth restriction implies failure of a fetus to meet its growth potential and is associated with increased perinatal mortality and morbidity. Therefore, antenatal detection of fetal growth restriction is of major importance in an attempt to deliver improved clinical outcomes. The most commonly used approach towards screening for fetal growth restriction is by means of sonographic fetal weight estimation, to detect fetuses small for gestational age, defined by an estimated fetal weight <10th percentile for gestational age.

Gestational impaired glucose tolerance (GIGT)-induced suppression of fetal thyroid secretion: effect on fetal outcome.

J Matern Fetal Neonatal Med 2018 Jan 31:1-5. Epub 2018 Jan 31.

c Department of Obstetrics & Gynaecology , JIPMER , Puducherry , India.

Introduction: Gestational impaired glucose tolerance (GIGT) is a milder form of gestational diabetes mellitus (GDM), which is often poorly managed. Although, GDM is known to be associated with increased incidence of thyroid dysfunction, no study has been done to study the effect of GIGT on thyroid status and its effect on fetal outcome. Here, we carried out a study to assess thyroid function and glycemic status in both maternal and cord blood of the subjects with GIGT, and to find their association with the fetal outcome. Read More

Monitoring the Postnatal Growth of Preterm Infants: A Paradigm Change.

Pediatrics 2018 02 4;141(2). Epub 2018 Jan 4.

Nuffield Department of Obstetrics & Gynaecology and Oxford Maternal & Perinatal Health Institute, Green Templeton College and.

There is no consensus regarding how the growth of preterm infants should be monitored or what constitutes their ideal pattern of growth, especially after term-corrected age. The concept that the growth of preterm infants should match that of healthy fetuses is not substantiated by data and, in practice, is seldom attained, particularly for very preterm infants. Hence, by hospital discharge, many preterm infants are classified as postnatal growth-restricted. Read More

Comparison of conventional 2D ultrasound to magnetic resonance imaging for prenatal estimation of birthweight in twin pregnancy.

Am J Obstet Gynecol 2018 01 16;218(1):128.e1-128.e11. Epub 2017 Oct 16.

Department of Obstetrics and Gynecology, University Hospital Brugmann, Université Libre de Bruxelles, Brussels, Belgium. Electronic address:

Background: During prenatal follow-up of twin pregnancies, accurate identification of birthweight and birthweight discordance is important to identify the high-risk group and plan perinatal care. Unfortunately, prenatal evaluation of birthweight discordance by 2-dimensional ultrasound has been far from optimal.

Objective: The objective of the study was to prospectively compare estimates of fetal weight based on 2-dimensional ultrasound (ultrasound-estimated fetal weight) and magnetic resonance imaging (magnetic resonance-estimated fetal weight) with actual birthweight in women carrying twin pregnancies.

New Option in the Lives Saved Tool (LiST) Allows for the Conversion of Prevalence of Small-for-Gestational-Age and Preterm Births to Prevalence of Low Birth Weight.

J Nutr 2017 11 13;147(11):2141S-2146S. Epub 2017 Sep 13.

Department of International Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD.

The Lives Saved Tool (LiST) is a software model that estimates the health impact of scaling up interventions on maternal and child health. One of the outputs of the model is an estimation of births by fetal size [appropriate-for-gestational-age (AGA) or small-for-gestational-age (SGA)] and by length of gestation (term or preterm), both of which influence birth weight. LiST uses prevalence estimates of births in these categories rather than of birth weight categories, because the causes and health consequences differ between SGA and preterm birth. Read More

Fractional fetal thigh volume in the prediction of normal and abnormal fetal growth during the third trimester of pregnancy.

Am J Obstet Gynecol 2017 10 23;217(4):453.e1-453.e12. Epub 2017 Jun 23.

Maternal and Fetal Health Research Center, Institute of Human Development, University of Manchester, Manchester, United Kingdom; St Mary's Hospital, Central Manchester University Hospitals National Health Service Foundation Trust, Manchester Academic Health Science Center, Manchester, United Kingdom.

Background: Currently, 2-dimensional ultrasound estimation of fetal size rather than fetal growth is used to define fetal growth restriction, but single estimates in late pregnancy lack sensitivity and may identify small for gestational age rather than growth restriction. Single or longitudinal measures of 3-dimensional fractional thigh volume may address this problem.

Objective: We sought to derive normal values for 3-dimensional fractional thigh volume in the third trimester, determine if fractional thigh volume is superior to 2-dimensional ultrasound biometry alone for detecting fetal growth restriction, and determine whether individualized growth assessment parameters have the potential to identify fetal growth restriction remote from term delivery.
