摘要
目的评价不同胎龄晚期早产儿(late preterm infants,LPI)的出生体重(birth weight,BW)和矫正胎龄(correct age,CA)1、3、6月龄时的体格生长情况,为早产儿长期体格生长随访提供监测重点。方法收集2010年5月至2011年9月就诊的287例LPI相关资料,评价LPI的BW和其在CA 1、3、6月龄时的体格生长情况。结果 (1)287例LPI中,胎龄34～34+6周和35～35+6周LPI平均BW低于1986年中国15城市不同胎龄新生儿参考值(P<0.05);胎龄36～36+6周单胎LPI(128例)平均BW高于1986年中国15城市不同胎龄新生儿参考值(P<0.05)。(2)在CA 1、3、6月时,90%以上LPI的各项生长指标达到或超过P3水平。CA 1、3月龄时,年龄别体重和头围明显大于2005年我国九市城区7岁以下正常儿童参考值(P<0.05)。(3)各CA的年龄别身长与参考值差异均无统计学意义。结论与1986年中国15城市不同胎龄新生儿BW值比较,LPI的BW有变化,提示我国不同胎龄新生儿BW标准需间隔一定时间后重新调查制定。LPI在CA 6月龄前存在超重的危险,需要更长期的监测。LPI的身长的生长应作为今后LPI生长随访监测的重点。
Objective To evaluate birth weights （BW） in late preterm infants （LPI） with different gestational ages （GA） and their physical growths at correct ages （CA） 1, 3 and 6 months. Methods A total of 287 LPIs were recruited for a cohort study between May 2010 and September 2011. Birth weights （BW） in infants with different gestational ages and their physical growths at CA 1,3 and 6 months were evaluated. Results Of the 287 LPIs, mean BW in LPIs with gestational ages of 34-34 6and 35-35 ＋6 weeks was significantly lower than the reference value from a physical growth investigation on newborns of 15 cities of China in 1986 （P 〈 0.05）. However, mean BW in singleton LPIs （ n = 128） with gestational ages of 36-36 6weeks was significantly higher than the reference value （P 〈 0.05） . At CA 1,3 and 6 months, more than 90% LPIs reached P3 level in weights for age, length for age and head circumference for age. At CA 1 and 3 months, weight for age and head circumference for age in the LPIs were statistically higher than the reference values of physical growth in children under 7 years from nine cities of china in 2005 （P 〈 0.05）. Mean length for age at CA 1, 3 and 6 months was not significantly different from the reference value. Conclusions There are obvious differences in BW in the LPIs compared with the reference value from a physical growth investigation on newborns of 15 cities of China in 1986, suggesting that the reference value of BW at different gestational ages needs to be updated in a certain interval. Before CA 6 months, there is a risk of overweight in LPIs and long-term monitoring is necessary. Growth of length should be followed-up for a long time.
