摘　　要：目的观察不同胎龄早产儿出院后体格生长的差异。探讨影响早产儿早期体格生长的可能因素。方法在出院后随访的早产儿中,选择资料完整的114例,按出生时胎龄进行分组,比较其校正胎龄约40周、校正月龄1个月、3个月、6个月的体质量、身长、头围差异。收集可能的影响变量,采用单因素分析,筛选出影响早期体格生长的可能因素,再行多重线性回归分析。结果两两比较,校正胎龄40周时,28~30周、30^(+1)~32周组身长与32^(+1)~34周比较,28~30周组头围与32^(+1)~34周比较,差异有统计学意义(P<0.05);校正1个月龄时,28~30周组体质量与其他组比较差异均有统计学意义(P<0.05);此组身长与32^(+1)~34周比较,差异有统计学意义(P<0.05);校正6个月龄时,32^(+1)~34周身长与34^(+1)~36^(+6)周组比较差异有统计学意义(P<0.05)。结论早期营养是早产儿体格生长的重要影响因素,父母文化程度高低可影响早产儿体格生长。Objective To investigate the physical growth of premature infants born at different gestational ages,and to explore the possible influencing factors for early-life physical growth in premature infants. Methods A total of 114 premature infants, presenting with complete medical data as identified in follow-up after hospital discharge, were allocated to groups according to their gestational age at birth. Body weight, length, and head circumference at correct-ed gestational age of 40 weeks, corrected ages of 1, 3 and 6 months were compared among groups. Possible influenc-ing variables were subjected to univariate analysis to select factors related to early-life physical growth. The latter were subjected to multiple linear regression analysis. Results By pair-wised comparison, there were significant differences in length at corrected gestational age of 40 weeks between infants born at gestational weeks 28-30 or 30^（＋1）-32 and those born at weeks 32^（＋1）-34, and in head circumference between infants born at gestational weeks 28-30 and those at weeks 32^（＋1）-32（all P〈0.05）. At the corrected age of 1 month, the body weight of infants born at gestational weeks 28-30 was statistically different from that in the other groups（P〈0.05）. In addition, the length of these infants was significantly different compared with infants born at weeks 32^（＋1）-34 weeks（P〈0.05）. At the corrected age of 6 months, there was a significant difference in length between infants born at gestational weeks 32^（＋1）-34 and those born at weeks 34^（＋1）-36（P〈0.05）. Conclusion Early nutrition is an important influencing factor for physical growth in premature infants.The education level of parents may affect the physical growth of premature infants.
