Objectives: To correlate fetal abdominal subcutaneous and skin thickness with birthweight and delivery indices. Methods: 65 patients were recruited during labor. The fetal abdominal subcutaneous and skin thickness (FASST) was assessed by measuring the distance from outer skin edge to rib margin at the level of the abdominal circumference. FASST was compared to birth weight, maternal preand post-delivery weight, maternal weight change, route of delivery, gender, maternal age, and gestational age. Results: Gestational age at recruitment was 39.61 ± 1.24 weeks (mean ± standard deviation). The interval from FASST measurement to delivery ranged from 1 to 34 hours. FASST measurements correlated strongly with birth weight (r = 0.643, P < .001). There were weak correlations with gestational age (r = 0.287, P = 0.021), maternal weight at delivery (r = 0.270, P = 0.032), and maternal weight gain during pregnancy (r = 0.345, P = 0.007). There was no difference in cesarean section resulting from arrest of labor. Macrosomic fetuses had thicker FASST (55.03 ± 9.05 mm) compared to others (43.45 ± 7.33 mm) (P = 0.01). Females had thicker FASST (45.92 ± 7.49 mm) compared to males (42.12 ± 7.61 mm) (P = 0.047). Conclusions: FASST measurements positively correlate with birthweight, maternal weight & female gender. These preliminary findings demonstrate FASST as a potentially promising tool for assessing intrapartum fetal weight.
