【摘要】：目的了解1岁内晚期早产儿（Late preterm infants, LPI）体格生长状况，为正确评价LPI体格生长提供参考依据。方法2010年5月至2011年11月，在重庆医科大学附属儿童医院儿保科收集婴儿体格生长资料。以同期足月儿（Full term infants, FTI）作为对照组，比较LPI和FTI年龄的体重Z值（Weight-for-age Z-score, WAZ）、年龄的身长Z值(Length-for-age Z-score, LAZ)、年龄的头围Z值（Headcircumference-for-age Z-score, HCZ）、身长的体重Z值（Weight-for-length Z-score, WLZ）及生长速度（ΔWAZ、ΔLAZ、ΔHCZ）。以出生体重（Birth weight, BW）为观察指标,比较LPI的BW与1986年中国15城市不同胎龄新生儿BW的差异。结果（1）共收集LPI309人，FTI418人。LPI的BW均值（2518.05±463.80）g明显小于FTI（3225.91±404.91）g（p0.01）。34-35周LPI的BW均值低于1986年中国15城市不同胎龄新生儿BW值，36周LPI的BW均值高于参考值；（2）与FTI比较，WAZ和HCZ的生长水平在6～月龄前LPI的水平较低，8～月龄时达到FTI水平，而LAZ在1岁内仍未达到FTI水平（p0.0001）；WLZ水平与FTI相同；（3）矫正月龄1月龄时，，LPI的各项体格指标已超过FTI水平，有统计学差异;（4）1岁内LPI组体格生长速度均值明显大于FTI(p0.0001)，ΔWAZ_(1-4)、ΔLAZ_(1-4)、ΔLAZ_(4-8)和ΔHCZ_(1-4)分别为1.74±0.89、1.24±0.79、0.79±0.71和0.98±0.83;（5）矫正月龄后，4～、5～、6～月龄LPI低体重的发生率仍明显高于FTI；5～和6～月龄消瘦的发生率较FTI高，有统计学差异；在8～月龄段LPI超重发生率高于FTI（p=0.0475）；矮小的发生率与FTI无明显差异。结论（1）与1986年中国15城市不同胎龄新生儿BW值比较，LPI的BW有明显变化，提示我国不同胎龄BW标准也应像儿童体格生长标准一样，间隔一定时间后重新调查制定；（2）评价LPI体格生长指标时，矫正其胎龄的时间值得进一步研究；（3）LPI体格生长速度较FTI快，且有追赶性生长;（4）LPI出现体格偏离的可能比FTI大。
[Abstract]:Objective to investigate the physical growth status of late preterm infants (LPI) in late preterm infants within one year old and to provide a reference for the correct evaluation of LPI growth. Methods from May 2010 to November 2011, The data of physical growth of infants were collected from the Department of Infant Care, affiliated Children's Hospital of Chongqing Medical University. Full term infants (FTI) were used as control group. The body weight Z value of LPI and FTI was compared with that of Weight-for-age Z-score, WAZZ, length Z of age, Z value of Length-for-age Z-scoreer, Z value of head circumference of age and head circumference Z-scoreage, LPI, weight Z value of body length Weight-for-length Z-score, WLZ) and growth rate (螖 WAZ, 螖 laz, 螖 HCZ). The birth weight weight (BW) was used as the index of observation. The difference between BW of LPI and 15 cities in China in 1986 was compared. Results 1) the BW mean value of LPI309 was 2518.05 卤463.80 g lower than that of FTI(3225.91 卤404.91 g 路34-35 weeks LPI was lower than that of 15 cities with different gestational age in 1986. The BW value of different gestational age neonates in 15 cities in China was lower than that of LPI in 15 cities in China in 1986.The mean BW value of LPI was significantly lower than that of FTI(3225.91 卤404.91g. 34-35 weeks. The mean BW of LPI at 36 weeks was higher than that of reference. Compared with FTI, the growth level of LPI and HCZ reached FTI level at the age of 8 months. However, LAZ did not reach the level of FTI within 1 year old and the same level as FTI (P 0.0001). The physical indexes of LAZ were higher than that of FTI at the age of 1 month. The average physical growth rate of LPI group within 1 year old was significantly higher than that of FTIIp 0.0001, 螖 WAZS 1-4, 螖 LAZS 1-4, 螖 LAZAZHAN 4-8) and 螖 HCZS 1-4) were 1.74 卤0.891.24 卤0.790.79 卤0.71 and 0.98 卤0.83f5) respectively. The incidence of low body weight in LPI was still significantly higher than that in FTI5- and 6- month old compared with FTI (P < 0.05). The incidence of overweight of LPI was higher than that of FTI at the age of 8 months. There was no significant difference between the incidence of dwarf and that of FTI. Conclusion the BW of newborn infants of different gestational ages in 15 cities in China was significantly different from that in 15 cities of China in 1986. It is suggested that different gestational age BW standards in China should be similar to those of children's physical growth standard, and should be re-investigated and established after a certain interval.) when evaluating the LPI physical growth index, the time of correcting the gestational age is worth further studying. The physical growth rate of LPI is faster than that of FTI. The physical deviation of LPI with catch-up growth was more likely than that of FTI.
