Crown-Rump Length Measured in the Early First Trimester as a Predictor of Low Birth Weight
نویسندگان
چکیده
The aim of this study is to assess the association between crown-rump length (CRL) measured before the 10th gestational week and birth weight. Results from 316 transvaginal ultrasonography scans at the 46th, 53rd, 60th, 67th, and 74th days of pregnancy were compared in low birth weight (LBW) versus normal birth weight groups. A positive correlation between CRL and birth weight was observed when CRL was measured at days 60, 67, and 74. CRL measured on the 67th day of pregnancy was significantly smaller in the LBW group than in the normal birth weight group. A cut-off value of CRL=26.5 mm measured at day 67 has the highest power to predict LBW.

Background: Recent studies have suggested that impaired fetal growth are indicators that may be present in the first trimester. The aim of this study was to investigate the relationship between crown-rump length (CRL) and pregnancy associated plasma protein-A (PAPP-A) measurements in first trimester for low birth weight (LBW).Methods: This prospective cohort study were on 120 pregnant women in ...
متن کاملFirst-trimester growth and the risk of low birth weight.
BACKGROUND Previous studies have demonstrated a correlation between first-trimester size and birth weight. It is not known, however, whether low birth weight is related to first-trimester growth. We sought to determine whether the risk of low birth weight and birth weight that was low for gestational age is related to the size of the embryo or the fetus in the first trimester. METHODS From a ...

متن کاملCrown-rump length discordance in twins in the first trimester and its correlation with perinatal complications*
BACKGROUND A difference more than 15-40% in birth weight of twins can predict perinatal complications. As significant difference in twins growth has a very important effect on pregnancy and perinatal complications, this study aimed to evaluate crown-rump length discordance (ΔCRL) in the first trimester of pregnancy and its correlation with perinatal complications. METHODS A total number of 11...
