Abstract Background Offspring of women with type 1 diabetes are at increased risk of accelerated fetal growth which is associated with perinatal morbidity. Growth standards are used to identify large- or small- for gestational age (LGA, SGA) infants. Our aim was to examine which growth standards identify infants at risk of perinatal complications during the Continuous Glucose Monitoring in Type 1 Diabetes Pregnancy Trial (CONCEPTT). Methods This was a pre-specified analysis of CONCEPTT involving 225 pregnant women from 31 international centres. Infants were weighed immediately at birth and GROW, INTERGROWTH and WHO centiles calculated. Unadjusted logistic regression identified the associations between different growth standards and perinatal outcomes including preterm delivery, Caesarean delivery, neonatal hypoglycaemia, hyperbilirubinaemia, respiratory distress, neonatal intensive care unit (NICU) admission and a composite neonatal outcome. Results Accelerated fetal growth was common, with mean birthweight percentiles of 82.1, 85.7 and 63.9 and LGA rates of 62%, 67% and 30% using GROW, INTERGROWTH and WHO standards respectively. Corresponding rates of SGA were 2.2%, 1.3% and 8.9% respectively. All standards were associated with some but not all perinatal outcomes studied. Infants born >97.7 th centile were at highest risk of complications. Conclusions WHO standards underestimated birthweight centile. GROW and INTERGROWTH standards identified similar numbers of infants as LGA and SGA with GROW showing stronger associations with neonatal hypoglycaemia, hyperbilirubinaemia and NICU admission. Infants with suspected birthweight >97.7th centile according to any standard may require extra surveillance. Definitions of LGA and SGA should be re-evaluated in diabetic pregnancy.

Abstract Background Offspring of women with type 1 diabetes are at increased risk of fetal growth patterns which are associated with perinatal morbidity. Our aim was to compare rates of large- and small-for-gestational age (LGA; SGA) defined according to different criteria, using data from the Continuous Glucose Monitoring in Type 1 Diabetes Pregnancy Trial (CONCEPTT).Methods This was a pre-specified analysis of CONCEPTT involving 225 pregnant women and liveborn infants from 31 international centres. Infants were weighed immediately at birth and GROW, INTERGROWTH and WHO centiles were calculated. Relative risk ratios, sensitivity and specificity were used to assess the different growth standards with respect to perinatal outcomes, including neonatal hypoglycaemia, hyperbilirubinaemia, respiratory distress, neonatal intensive care unit (NICU) admission and a composite neonatal outcome. Results Accelerated fetal growth was common, with mean birthweight percentiles of 82.1, 85.7 and 63.9 and LGA rates of 62%, 67% and 30% using GROW, INTERGROWTH and WHO standards respectively. Corresponding rates of SGA were 2.2%, 1.3% and 8.9% respectively. LGA defined according to GROW centiles showed stronger associations with preterm delivery, neonatal hypoglycaemia, hyperbilirubinaemia and NICU admission. Infants born >97.7th centile were at highest risk of complications. SGA defined according to INTERGROWTH centiles showed slightly stronger associations with perinatal outcomes. Conclusions GROW and INTERGROWTH standards performed similarly and identified similar numbers of neonates with LGA and SGA. GROW-defined LGA and INTERGROWTH-defined SGA had slightly stronger associations with neonatal complications. WHO standards underestimated size in preterm infants and are less applicable for use in type 1 diabetes.Trial registration: This trial is registered with ClinicalTrials.gov. number NCT01788527.

Increased Risk

Small-for-gestational-age (SGA) infants have been associated with increased risk of adverse perinatal outcomes (APOs). In this work, we assess the predictive ability of the ultrasound-estimated percentile weight (EPW) at 35 weeks of gestational age to predict late-onset SGA and APOs, according to six growth standards, and whether the ultrasound–delivery interval influences the detection rate. To this purpose, we analyze a retrospective cohort study of 9585 singleton pregnancies. EPWs at 35 weeks were calculated to the customized Miguel Servet University Hospital (MSUH) and Figueras standards and the non-customized MSUH, Fetal Medicine Foundation (FMF), INTERGROWTH-21st, and WHO standards. As results of our analysis, for a 10% false positive rate, the detection rates for SGA ranged between 48.9% with the customized Figueras standard (AUC 0.82) and 60.8% with the non-customized FMF standard (AUC 0.87). Detection rates to predict SGA by ultrasound–delivery interval (1–6 weeks) show higher detection rates as intervals decrease. APOs detection rates ranged from 27.0% with FMF to 7.9% with the Figueras standard. In conclusion, the ability of EPW to predict SGA at 35 weeks is good for all standards, and slightly better for non-customized standards. The APO detection rate is significantly greater for non-customized standards.

No Gold Standard

Small for gestational age (SGA) and fetal growth restriction (FGR) is difficult to define exactly. In this pregnancy condition, the fetus does not reach its biological growth potential as a consequence of impaired placental function, which may be because of a variety of factors. Fetuses with FGR are at risk for perinatal morbidity and mortality, and poor long-term health outcomes, such as impaired neurological and cognitive development, and cardiovascular and endocrine diseases in adulthood. At present no gold standard for the diagnosis of SGA/FGR exists. The first aim of this review is to: summarize areas of consensus and controversy between recently published national guidelines on small for gestational age or fetal growth restriction; highlight any recent evidence that should be incorporated into existing guidelines. Another aim to summary a number of interventions which are being developed or coming through to clinical trial in an attempt to improve fetal growth in placental insufficiency. Key words: fetal growth restriction (FGR), Small for gestational age (SGA)
