Abstract

INTRODUCTION:

Fetal growth abnormality is associated with changes in the soft tissue mass, which is decreased in growth restricted fetuses and increased in macrosomia.

OBJECTIVE:

To correlate fetal abdominal subcutaneous tissue thickness (FASTT) measured by ultrasound at term and birth weight and to obtain a cut-off value of FASTT to predict large and small for gestational age babies in our population.

METHODS:

FASTT was measured at the anterior 1/3(rd) of abdominal circumference by ultrasound after 36 weeks and weight of the baby measured after birth.

RESULTS:

There was positive correlation between FASTT and birth weight. FASTT of 6.25 mm was sensitive to predict large for gestational age (LGA) babies and had a high negative predictive value; FASTT measurement for prediction of small babies with birth weight < 2500 g was not sensitive.

CONCLUSION:

FASTT can be used as an additional indicator to predict large for gestational age babies along with other known birth weight indicators.
