Current parameters to measure fetal size may not accurately identify those fetuses at nutritional risk. Ultrasound-generated estimates of fetal fat may be useful in the evaluation of fetal growth abnormalities. Ojectives: To determine the correlation of fetal abdominal subcutaneous tissue thickness at term with other biometric measurements and neonatal outcome. Methodology: Included were women with term singleton pregnancies within one week of delivery at the Department of Obstetrics and Gynecology. Excluded were women whose fetuses had congenital anomalies. Maternal age, gravidity, menstrual age at time of scan and presence of maternal complications were documented. Thickness of the subcutaneous fat tissue at the anterior abdominal wall was measured sonographically by board certified obstetrician sonologists and correlated with BPD, HC, AC, SEFW and actual birthweight using Pearson's correlation coefficient and linear regression. T-test and ROC analysis were also done. For all tests, a 95% confidence level was considered significant. Results: FASTT was significantly correlated with AC, SEFW and actual birthweight. LGAs had significantly thicker FASTT than AGAs. Accuracy of FASTT in predicting a CS mode of delivery, with a cutoff of
