Abnormal fetal development such as macrosomia can cause some complications on both fetus and mother.The measurement of fetal anterior abdominal wall thickness (FAWT) is an easy examination that it can be obtained during an examination of a pregnant woman by ultrasound. Macrosomia for fetus can lead to some morbidities. It can affect perinatal outcome and increase childbirth complications and operative birth. There are some studies scrutinizing the relationship between FAWT and diabetes in the literature. However there are few studies which scrutinize effect of FAWT on both abnormal fetal development and adverse perinatal outcomes in non-diabetic pregnancies and non high risk pregnancies. Hence the investigators wonder if FAWT can anticipate birth-weight or macrosomic infant or perinatal outcome regarding with macrosomia in the second trimester.
