大多数先前发表的出生体重指数表作为胎龄的函数，都是来自于不精确的胎龄测定的新生儿。为了提高新生儿出生体重表的准确性，我们制定了一个出生体重表的基础上测量一组新生儿谁有准确的妊娠日期的产前孕早期超声检查。通过匹配数据库的产科超声波检查，在我们的机构出生记录超过5年的时间，3718名新生儿与妊娠日期的头三个月超声检查确定。将统计平滑和回归技术应用于出生时胎龄和出生体重数据，以制定第10、50、90周和妊娠25周后其他体重数据表。从我们的人群中开发的体重表在25至35周时比以前的表具有更低的第50和第90百分位数体重，以及更窄的第10至第90百分位数范围。在39至43周时，我们的第10、50和90百分位数权重高于前几张表中的权重。我们的新生儿体重表是根据新生儿的准确测年数据制定的，它可以改进胎龄体重表的分配，并更准确地诊断胎儿和新生儿的生长障碍。
Most previously published tables of birth weight percentiles as a function of gestational age have been derived from neonates with imprecise gestational dating. In order to improve the accuracy of neonatal birth weight percentiles, we developed a birth weight table based on measurements from a group of neonates who had accurate gestational dating by prenatal first trimester ultrasonography. By matching a database of obstetrical ultrasonograms over a 5 year period to birth records at our institution, 3718 newborn infants with gestational dating by first trimester ultrasonography were identified. Statistical smoothing and regression techniques were applied to gestational age at birth and birth weight data to develop a table for the 10th, 50th, 90th, and other weight percentiles for 25 weeks of gestation onward. The weight table developed from our population has lower 50th and 90th percentile weights, and narrower 10th to 90th percentile ranges, at 25 to 35 weeks than in prior tables. At 39 to 43 weeks, our 10th, 50th, and 90th percentile weights are higher than those in previous tables. Our weight table for newborn infants, based on measurements from neonates with accurate dating, permits improved assignment of weight percentiles for gestational age and more accurate diagnosis of growth disorders in fetuses and neonates.
