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.
引言
胎儿生长异常与软组织质量的变化相关，生长受限胎儿的软组织质量减少，巨大儿的软组织质量增加。
目的
将足月时超声测量的胎儿腹部皮下组织厚度（FASTT）与出生体重进行关联，并获得FASTT的截断值，以预测我们人群中适于胎龄儿的大小。
方法
36周后通过超声测量腹围前1/3处的FASTT，并在出生后测量婴儿体重。
结果
FASTT与出生体重呈正相关。6.25mm的FASTT对预测大于胎龄（LGA）儿敏感，具有较高的阴性预测值；FASTT测量对预测出生体重<2500g的小样儿不敏感。
结论
FASTT可作为一种额外指标，与其他已知的出生体重指标一起用于预测大于胎龄儿。
