Abstract

Purpose: To identify the ability of the definitions of fetal growth restriction (FGR) according to the Japan Society of Obstetrics and Gynecology (JSOG) and the Society for Maternal-Fetal Medicine (SMFM) to predict small-for-gestational-age (SGA) neonates.

Methods: A retrospective cohort of Japanese women with singleton pregnancies who delivered at our hospital was analyzed. The primary outcome measure was the incidence of SGA neonates. The odds ratios (ORs) of SGA neonates according to the FGR definitions at 18 weeks (17-20 weeks, period 1) and 28 weeks (27-30 weeks, period 2) were calculated.

Results: During periods 1 and 2, the incidence rates of SGA neonates were 7.6% and 7.7%, respectively. The ORs of the JSOG and SMFM definitions were 8.24 [95% confidence interval (CI) 4.27-14.4] and 5.88 (95% CI 3.90-8.88), respectively, during period 1 and 22.7 (95% CI 12.6-40.8) and 15.5 (95% CI 10.4-23.1), respectively, during period 2. Compared to the JSOG definition, the SMFM definition was more sensitive for predicting SGA neonates. During both periods, the positive likelihood ratio (LR +) of the JSOG definition was higher than that of the SMFM definition for predicting SGA neonates.

Conclusion: The JSOG definition more strongly predicts SGA neonates and is associated with a higher LR + . The SMFM definition is highly sensitive for screening fetuses at risk for SGA status.

日本妇产科学会胎儿生长限制定义预测小胎龄新生儿的检出率

目的：探讨日本妇产科学会（JSOG）和母胎医学会（SMFM）胎儿生长受限（FGR）定义预测小胎龄儿（SGA）的能力。方法：对在我院分娩的日本单胎妊娠妇女进行回顾性队列分析。主要结局指标是SGA新生儿的发生率。计算18周（17-20周，第1期）和28周（27-30周，第2期）根据FGR定义的SGA新生儿的比值比（ORs）。结果：第1期和第2期新生儿SGA发生率分别为7.6%和7.7%。在第一阶段，JSOG和SMFM定义的or分别为8.24[95%可信区间（CI） 4.27-14.4]和5.88 (95% CI 3.90-8.88)，在第二阶段，分别为22.7 （95% CI 12.6-40.8）和15.5 （95% CI 10.4-23.1）。与JSOG定义相比，SMFM定义对SGA新生儿的预测更为敏感。在这两个时期，JSOG定义的阳性似然比（LR +）高于SMFM定义对SGA新生儿的预测。结论：JSOG定义更能预测SGA新生儿，并与较高的LR +相关。SMFM定义对于筛查有SGA状态风险的胎儿是高度敏感的。
