Appropriate interpretation of monitored fetal growth throughout pregnancy in individual patients and populations is dependent upon the availability of adequate standards. Previously published standards either were based on small samples, data decades old or were characteristic of foreign subpopulations. We have reviewed the data on a series of 46,575 singleton live births at Chang Gung Memorial Hospital from 1979 to 1989. The ratio of males to females was 1.08. The fetal growth pattern in the third trimester of pregnancy approximates a sigmoid curve. Fetal growth was most rapid from the 32nd to the 37th week of gestation with an average increase of 240 g per week. The birth weight declined beyond 42 weeks' gestation. There were significantly greater weight gains amongst male fetuses as compared to female fetuses from the 34th to the 42nd week of gestation. The mean birth weight recorded at 40 weeks' gestation in male and female newborns was 3,381 g and 3,262 g, respectively. Comparing the birth weight of term pregnancies using our data, with those of a previous, two-decade old report (1945-1967) by Chen, we found that birth weight were slightly higher in this study. The derived fetal growth curves are useful for clinical, public health, and investigational purposes.
在个体患者和人群中对整个孕期监测的胎儿生长情况进行恰当解读，取决于是否有足够的标准。先前公布的标准要么基于小样本、数十年前的数据，要么是外国亚人群的特征。我们回顾了1979年至1989年长庚纪念医院46575例单胎活产的数据。男女比例为1.08。妊娠晚期的胎儿生长模式近似于S形曲线。胎儿生长在妊娠第32周至37周最为迅速，平均每周增加240克。妊娠超过42周后出生体重下降。在妊娠第34周至42周期间，男性胎儿的体重增加明显高于女性胎儿。男性和女性新生儿在妊娠40周时的平均出生体重分别为3381克和3262克。将我们的数据中足月妊娠的出生体重与Chen之前一份20年前（1945 - 1967年）的报告中的数据进行比较，我们发现本研究中的出生体重略高。得出的胎儿生长曲线可用于临床、公共卫生和研究目的。
