The condition of low birth weight is compared in twins and in singletons in terms of birth weight distributions and with respect to factors such as the incidence of stillbirths, length of gestation, maternal age, parity, and legitimacy. In the light of demographic, biological, and developmental considerations, it is concluded that low birth weight in twins is a different condition from low birth weight in singletons and should be dealt with independently, especially in view of the different implications for child growth and survival.
就出生体重分布以及死产发生率、妊娠期长度、母亲年龄、产次和子女合法性等因素而言，对双胞胎和单胎的低出生体重情况进行了比较。根据人口统计学、生物学和发育方面的考虑，得出的结论是，双胞胎中的低出生体重与单胎中的低出生体重是不同的情况，应该独立处理，特别是考虑到对儿童生长和生存的不同影响。
