Abstract

This study aimed to determine the correlation between the placental thickness-to-estimated foetal weight ratio on midterm ultrasonography and small-for-gestational-age (SGA) infants. In this retrospective study, the placental thickness at the umbilical cord insertion site was measured and adjusted for foetal body weight at 18–24 weeks gestation. Investigators compared the data of women who delivered SGA infants (birth weight <10th percentile) with those of women who delivered non-SGA infants. Among the 1281 women in this study, those who delivered SGA infants were younger and less likely to be obese. Women with higher placental thickness-to-estimated foetal weight ratios delivered more SGA infants. In logistic regression analysis, a higher placental thickness-to-estimated foetal weight ratio remained associated with SGA infants. Since the placental thickness-to-estimated foetal weight ratio in midterm pregnancy was associated with infant body weight at delivery, this ratio could be an effective, adjunctive screening marker for predicting SGA status.
