Background: Fetal growth restriction is defined as the failure of the fetus to achieve its full growth potential. The present study aimed to investigate the application of first trimester screening in the prediction of small for gestational age (SGA).
Methods: This cohort study was conducted on the consecutive and unselected women with singleton pregnancies undergoing routine first-trimester examinations in a health center affiliated to Neyshabur University of Medical Sciences in Razavi Khorasan Iran during February 2014-March 2016. Subjects received a first-trimester visit by a physician, which included the entry of basic maternal characteristics, medical history, measurement of maternal weight and height, ultrasound examination for fetal anatomy, and measurement of crown-rump length to assess gestational age.
Results: SGA was significantly correlated with maternal age, parity, and body mass index. Furthermore, a significant association was observed between SGA and smoking habits in the mothers.
Conclusion: According to the results, first trimester screening was a useful method for the prediction of SGA.
