Placental growth is concordant with fetal growth and any impairment would negatively impact fetal development and subsequent birthweight that is vital for newborn survival.
The aim of the study was to determine the relationship between placenta thickness and birth weight.
This prospective cohort study carried out at the University of Nigeria Teaching Hospital Enugu, Nigeria, involved 80 consecutive pregnant women with thick placenta (>4 cm) and another 80 in the control group with normal placenta thickness (2.5-4 cm) and matched for parity and maternal weight between 38 and 40 weeks of gestation. Both groups were followed up until delivery and the neonatal parameters were measured. Data analysis was descriptive and inferential at 95% confidence levels using Statistical Package for the Social Sciences software version 20.
The mean placental thickness at recruitment were 5.3 ± 0.7 cm and 3.7 ± 0.2 cm among the study and control groups, respectively. The study group had significantly higher birthweight, head circumference, and crown-heel length compared to the control group (P < .05). There was a positive linear correlation between placental thickness and birth weight, head circumference, and crown-heel length.
This study demonstrated that sonographic measurement of placental thickness antenatally is a reliable predictor of birth weight and other neonatal anthropometric parameters.
胎盘生长与胎儿生长一致，任何损害都会对胎儿发育以及对新生儿生存至关重要的出生体重产生负面影响。
本研究的目的是确定胎盘厚度与出生体重之间的关系。
这项前瞻性队列研究在尼日利亚埃努古的尼日利亚大学教学医院进行，纳入了80名连续的胎盘增厚（>4厘米）的孕妇，以及另一组80名胎盘厚度正常（2.5 - 4厘米）的对照组孕妇，两组孕妇在妊娠38至40周时的产次和母亲体重相匹配。两组均随访至分娩，并测量新生儿参数。使用社会科学统计软件包20版在95%置信水平下进行描述性和推断性数据分析。
研究组和对照组在入组时的平均胎盘厚度分别为5.3±0.7厘米和3.7±0.2厘米。与对照组相比，研究组的出生体重、头围和顶臀长度显著更高（P<.05）。胎盘厚度与出生体重、头围和顶臀长度之间存在正线性相关。
本研究表明，产前超声测量胎盘厚度是出生体重和其他新生儿人体测量参数的可靠预测指标。
