To generate contemporary postnatal growth curves for hospitalized very low birth weight infants.
Retrospective survey.
Tertiary intensive care nursery.
All surviving singleton, appropriate-for-gestational age infants with birth weight < or = 1500 g, born January 1, 1987, to May 31, 1991, who did not develop necrotizing enterocolitis (N = 205).
Macronutrient intakes and body weights were recorded daily, with crown-heel length and occipital-frontal head circumference recorded weekly up to 105 days of age or hospital discharge, whichever occurred first. Growth curves were generated for four birth weight ranges: 501 through 750, 751 through 1000, 1001 through 1250, and 1251 through 1500 g. Compared to previously published growth curves, the current infants regained birth weight more quickly and exhibited larger average daily weight gains. These differences were most apparent in infants of lowest birth weight.
The "premature growth grid" constructed by Dancis et al more than 40 years ago may no longer be a useful standard of early postnatal growth for present-day very low birth weight, appropriate-for-gestational-age infants. The new weight curves are a more accurate reflection of current in-hospital growth trends, especially for infants weighing < or = 1000 g at birth.
为住院的极低出生体重儿绘制当代产后生长曲线。
回顾性调查。
三级重症监护病房。
所有存活的单胎、适于胎龄儿，出生体重≤1500g，于1987年1月1日至1991年5月31日出生，且未发生坏死性小肠结肠炎（N = 205）。
每日记录宏量营养素摄入量和体重，每周记录顶跟身长和枕额头围，直至105日龄或出院，以先到者为准。为四个出生体重范围绘制生长曲线：501至750、751至1000、1001至1250以及1251至1500g。与先前发表的生长曲线相比，当前的婴儿恢复出生体重更快，且平均每日体重增加更大。这些差异在出生体重最低的婴儿中最为明显。
40多年前由丹西斯等人构建的“早产生长图表”可能不再是当今极低出生体重、适于胎龄儿产后早期生长的有用标准。新的体重曲线更准确地反映了当前住院期间的生长趋势，尤其是对于出生体重≤1000g的婴儿。
