“…Additionally, the present study results were in accordance with the results recorded by Bhat et al [10], who found that the difference in mean FASTT between SGA and AGA babies was statistically significant (p value 0.032). Similarly, the difference in mean FASTT between LGA and AGA babies was also statistically significant (p value 0.000).…”

“…The current study concluded that FASTT showed a high statistically significant correlation with EFW by Hadlock formula and BW (birth weight); also, a high statistically significant difference between each of the birth weight categories regarding the value of EFW by Hadlock formula as well as by FASTT was noted. Both EFW and FASTT showed higher values in LGA category than AGA and SGA categories and also showed higher values in AGA category than SGA category Bhat et al [10] also agreed with our results; they plotted birth weight against FASTT (scatter plot graph), and it showed a positive significant correlation between FASTT and birth weight obtained by Pearson's [13] demonstrated that FASTT may be useful in the assessment of fetal nutritional risk as they showed a significant correlation between subcutaneous tissue thickness, estimated fetal weight, and actual BW. Regarding the statistically significant difference of FASTT in different birth weight categories, Odthon et al [14] showed similar results; they studied the correlation between FASTT and birth weight.…”

“…Despite that, Bhat et al [10] also showed that FASTT was sensitive to predict large for gestational age (LGA) and not sensitive for SGA; a quite different cutoff value of FASTT for large babies was obtained (6.25 mm). Sensitivity for FASTT > 6.25 mm for large for gestational age babies was 79% and specificity is 70%.…”

Background: Commonly used ultrasound fetal weight estimation formulas show variable degrees of error which is more evident in fetuses with nutritional and metabolic issues; better accuracy of fetal weight estimation can be obtained by incorporation of fetal soft tissue parameters like the fetal subcutaneous tissue in the weight estimation process. The aim of this study was to assess the accuracy of fetal abdominal subcutaneous tissue thickness (FASTT) as an indicator of fetal birth weight. Results: FASTT showed a high significant statistical correlation with fetal birth weight (r = 0.94, P value = 0.00); it showed higher sensitivity for large for gestational age (LGA) than small for gestational age (SGA) (90.9% and 86.9%, respectively). The best cutoff value for the detection of LGA was ≥ 9.2 mm and ≤ 4.5 for SGA. FASTT showed lower accuracy than abdominal circumference (AC) as an indicator of LGA (92% versus 96%, respectively). Used alone, FASTT is less sensitive than Hadlock formula in both LGA and SGA (90.9% versus 94.5% in LGA and 86.9% versus 88.9% for SGA, respectively). There was no statistical correlation between FASTT and mode of delivery (r = 0.09, P value = 0.23) nor fetal gender (r = 0.15, P value = 0.11) Conclusion: FASTT is a good indicator of fetal birth weight especially LGA, yet it is less sensitive than AC in the prediction of LGA. It cannot be used as a predictor of mode of delivery and not affected by fetal gender.

“…German guidelines recommend to involve fetal growth-parameters into the treatment of GDM patients, focusing on fetal abdominal circumference (AC) and estimated fetal weight (EFW) [ 7 ]. Recently, several studies on fetal abdominal subcutaneous tissue (FAST) claiming this US parameter to be another noninvasive marker sensitive for the nutritional state of the fetus [ 8 , 9 , 10 ]. Most of these studies focused on the value of FAST in predicting fetal birth weight and especially LGA newborns.…”

Guidelines on the management of gestational diabetes (GDM) instruct physicians to involve ultrasound-based monitoring of fetal growth in addition to blood glucose. So far, glucose control besides clinical parameters like maternal body mass index (BMI) and gestational weight gain have been shown to predict neonatal outcome. We aimed to evaluate the discriminative ability of fetal abdominal subcutaneous tissue (FAST) in addition to standard ultrasound parameters like abdominal circumference (AC) and estimated fetal weight (EFW) for perinatal complications like large for gestational age (LGA), hypoglycemia, hyperbilirubinemia, mode of delivery and admission to neonatal intensive care unit (NICU). Ultrasound data and neonatal outcome was collected of 805 GDM cases from 2012 to 2016: 3205 FAST, 3195 AC-measurements and 3190 EFW calculations were included. AC, EFW and FAST increased linear with gestational age. Combining ultrasound and clinical parameters improved predictive power for LGA. In the subgroup where fetuses grow with an AC > 75th additional adding of FAST to standard ultrasound parameters increased predictive power for hypoglycemia. Our results confirm inclusion of ultrasound parameters to be beneficial in monitoring GDM pregnancies. Additional FAST determination revealed to be of potential clinical relevance in the subgroup AC > 75th percentile.

Objective: Infants born LGA are at an increased risk of short and longer term adverse outcomes. Understanding fetal growth and adiposity, and their trajectories may help inform interventions to prevent birth of LGA infants. We aimed to compare fetal growth and adiposity measures of infants born LGA with those born not LGA, to determine whether the discrepancy at birth was primarily due to larger size throughout gestation, or instead to different trajectories of fetal growth. Study Design: This was a secondary analysis of secondary outcomes of fetal growth and adiposity from three harmonized randomized trials – the LIMIT, GRoW, and Optimise randomized trials. These trials recruited women in early pregnancy, and a singleton gestation, from three major public metropolitan Adelaide maternity hospitals. Maternal BMI ranged from 18.5-≥40.0 kg/m2. Data were obtained from enrolled women who underwent research ultrasounds at 28 and 36 weeks’ gestation. Outcome measures were ultrasound measures of fetal biometry and adiposity. Results: Infants born LGA had larger fetal biometry measures, and higher growth trajectories, from 20 weeks’ gestation. Fetal adiposity measures were consistently larger among infants born LGA and these differences increased over time. We did not find evidence that the differences in biometry and adiposity measurements varied according to maternal BMI. Conclusions: Infants born LGA had larger fetal biometry measures at all time points from 20 weeks’ gestation, compared to infants born not LGA suggesting any interventions to prevent LGA likely need to commence earlier in pregnancy, or prior to conception.
