对563例双胎妊娠的胎儿生长情况进行了分析。双胞胎的出生体重受怀孕时间和合子的影响。在孕周32周之前，胎儿的宫内生长和体重与单胎妊娠相同。在这一阶段之后，胎儿的生长明显减缓。双胞胎的生长曲线相似，在妊娠39周后，双胞胎2的生长迟缓趋势增加。用第10百分位线表示的宫内生长迟缓，双胞胎1在妊娠31周时为1094 g， 36周时为1836 g， 40周时为2428 g。双胞胎2的相应数字分别为1131 g、1875 g和2337 g。
Analysis was made of fetal growth in 563 twin pregnancies. The birth weight of a twin is affected by the duration of pregnancy and zygosity. Intrauterine growth and weight is the same as a singleton pregnancy up to a gestational age of 32 wk. After this stage fetal growth slows markedly. The growth curves of both twins are similar with an increasing tendency towards growth retardation in twin 2 after 39 wk gestation. Intrauterine growth retardation, as represented by the 10th percentile line, for twin 1 joins 1094 g at 31 wk, 1836 g at 36 wk and 2428 g at 40 wk gestation. The corresponding figures for twin 2 are 1131 g, 1875 and 2337 g, respectively.
