The relationship between low birth weight, intrauterine growth retardation, and preterm delivery in infants born at a perinatal center is described. Between 20% and 30% of infants born weighing 500 to 2000 gm and nearly 50% of infants born weighing 2001 to 2750 gm had intrauterine growth retardation. For infants within the same low-birth weight group, infants with intrauterine growth retardation had one half to one sixth of the neonatal mortality rate of non-growth-retarded infants. However, only in the 501 to 1000 gm group did the difference in mortality between infants with and without intrauterine growth retardation substantially influence the composition of the group of survivors.
本文描述了某围产期中心出生的婴儿中低出生体重、宫内生长迟缓与早产之间的关系。出生体重在500至2000克之间的婴儿中，20%至30%存在宫内生长迟缓；出生体重在2001至2750克之间的婴儿中，近50%存在宫内生长迟缓。在同一低出生体重组的婴儿中，患有宫内生长迟缓的婴儿的新生儿死亡率是未患生长迟缓婴儿的二分之一至六分之一。然而，只有在501至1000克这一组中，有和没有宫内生长迟缓的婴儿之间的死亡率差异才对存活者群体的构成产生了实质性影响。
