In a retrospective study of 150 twins born between 1970-1977, birth weight, length, and head circumference was plotted against gestational age. In comparison to singletons, all 3 parameters were low normal. While length and head circumference values follow the growth pattern of singletons, prenatal birth weight shows a progressive decline toward maturity. The intrauterine growth pattern of twins resembles that of intrauterine growth retardation of singletons.
在一项对1970年至1977年出生的150对双胞胎的回顾性研究中，将出生体重、身长和头围与胎龄进行了绘图分析。与单胎相比，所有这三个参数均处于低正常水平。虽然身长和头围值遵循单胎的生长模式，但产前出生体重在接近足月时呈逐渐下降趋势。双胞胎的宫内生长模式类似于单胎的宫内生长迟缓模式。
