目标：为了制定一个目前的国家胎儿生长曲线，可以作为一个共同的参考点，由研究人员，以促进调查的预测因素和后果的小和大的胎龄交付。方法：1991年美国居民母亲的单胎活产（n = 3，134，879）用于绘制该曲线，并与先前发表的4条胎儿生长曲线进行比较。技术的开发，以解决与难以置信的出生体重胎龄组合的情况下，平滑胎儿生长曲线跨胎龄categoris.Results：在一般情况下，以前公布的胎儿生长曲线低估了1991年美国的参考曲线。这种低估是最明显的，在妊娠后期的几周，大约33-38 weeks.Conclusion：我们的研究结果表明，胎儿生长受限（FGR）的患病率将显着变化，这取决于胎儿生长曲线。此外，许多以前发表的胎儿生长曲线不再提供最新的参考，用于描述出生体重按胎龄的分布，并确定与整个美国最新的活产数据一致的FGR。
Objective: To develop a current national fetal growth curve that can be used as a common reference point by researchers to facilitate investigations of the predictors and consequences of small and large for gestational age delivery.Methods: Single live births to United States resident mothers in 1991 (n = 3,134,879) were used for the development of this curve, which was compared with four previously published fetal growth curves. Techniques were developed to address cases with implausible birth weight-gestational age combinations and to smooth fetal growth curves across gestational age categories.Results: In general, the previously published fetal growth curves underestimated the 1991 United States reference curve. This underestimation is most apparent during the latter weeks of gestation, approximately 33-38 weeks.Conclusion: Our findings indicate that the prevalence of fetal growth restriction (FGR) will vary markedly, depending on the fetal growth curve used. Furthermore, many previously published fetal growth curves no longer provide an up-to-date reference for describing the distribution of birth weight by gestational age and for determining FGR that is consistent with the most recent live birth data for the entire United States.
