Growth patterns of weight, length, and OFC complete through 12 months corrected age were determined for 122 VLBW infants who weighed 1,500 gm. or less and were 35 weeks or less gestational age at birth. Significant differences in growth were apparent when infants were grouped according to sex and appropriateness of intrauterine growth. When the mean values of each group were compared, the female AGA infants demonstrated growth at higher percentiles (NCHS term infant norms) for all three growth parameters (weight, length, and OFC). AGA male, SGA male, and SGA female infants all grew similarly, at lower percentiles for weight and length, when compared with the same norms. Growth in OFC was closest to term infant norms in all subgroups of infants. (formula; see text) Appropriateness of weight for length was determined for each of the infants at one year corrected age. The majority of the babies, regardless of subgroup, achieved weights and lengths greater than the 5th percentile and with normal weights for lengths. At 12 months corrected age, 30% remained below the 5th percentile in weight, 21% below the 5th percentile in length, and 14% below the 5th percentile in OFC. Eighteen infants (15%) demonstrated a disproportionately low weight for length (less than the 5th percentile).
对122名出生体重1500克及以下、胎龄35周及以下的极低出生体重儿，确定其矫正年龄至12个月时的体重、身长和头围生长模式。根据性别和宫内生长适宜性对婴儿进行分组时，生长差异明显。比较每组的平均值时，与相同标准相比，适于胎龄（AGA）的女婴在所有三个生长参数（体重、身长和头围）上的生长百分位数（美国国家卫生统计中心足月儿标准）更高。AGA男婴、小于胎龄（SGA）男婴和SGA女婴的生长情况相似，与相同标准相比，体重和身长的百分位数较低。所有亚组婴儿的头围生长最接近足月儿标准。（公式；见正文）在矫正年龄一岁时，确定每个婴儿的身长体重比是否适宜。大多数婴儿，无论亚组如何，其体重和身长均大于第5百分位数，且身长体重正常。在矫正年龄12个月时，30%的婴儿体重仍低于第5百分位数，21%的婴儿身长低于第5百分位数，14%的婴儿头围低于第5百分位数。18名婴儿（15%）的身长体重比过低（低于第5百分位数）。
