目的探讨不同胎龄初生儿生长发育与母亲分娩年龄的相关性,新生儿体格与母亲其他情况、喂养方式的关系。方法选择2012年1月~2014年1月深圳市重点医院分娩的初生儿219例作为研究对象,根据胎龄分为观察组早产儿93例和对照组足月儿126例。比较两组新生儿体格情况、母亲情况、前6个月的喂养方式等,并采用多元线性回归分析法进行相关性分析。结果观察组体重、身长、坐高以及头围显著小于对照组,母亲年龄≤25岁阶段的比例高于对照组,〉30岁的比例低于对照组,母亲文化程度在初中以下、前6个月采用人工喂养方式以及出现各种并发症的比例均显著高于对照组,有显著性差异（P〈0.05）。通过相关性分析发现,母亲年龄相对更高、母亲文化程度在初中及以上、前6个月采用母乳方式喂养以及母亲并发症比例越低的新生儿生长发育状况更好。3、6月龄观察组体重、身高小于对照组（P〈0.05）,12月龄两组新生儿无显著性差异（P〉0.05）。结论深圳不同胎龄新生儿生长发育呈现不同趋势,其中足月儿体格明显更好。母亲年龄及文化程度相对高、采用母乳喂养及母亲妊娠并发症比例越低的新生儿生长发育越好。并且在新生儿出生后采用健康的护理方式对其后期生长发育具有促进作用。

英文摘要：

Objective To analyze the different gestational age newborn growth development and maternal age and correlation,and to explore the relationship between neonatal physical and other mothers,feeding patterns.Methods Selected hospital delivery of219 cases of new-born infants as the object of study.According to the gestational age were divided into 93 preterm infants and full-term infants in the observation group,126 cases were recorded as control group.Contrast two groups of growing condition.Results The observation group＇s weight,height,sitting height and head circumference were significantly lower than the control group,less than 25 of the proportion of gestation age was higher than that of control group,age〉 30 was lower than the control group,mother education level below junior middle school,six months before the artificial feeding and the proportion of various complications were significantly higher than that of the control group.The differences were statistically significant（P〈0.05）.The correlation analysis showed that higher maternal age,mother cultural degree in junior high school and above,six month before the breast feeding mother and complication rate,the lower the neonatal growth and development of better.At last,the weight and height of the observation group were less than those of the control group by the same nursing method,in 3,6months of age,the body weight and height data of the observation group were less than the control group,there was no significant differences between the two groups of newborns in 12 months of age.Conclusion The growth and development of Shenzhen in different gestational age showed different trends,which significantly better physique in full-term infants,mother＇s age and culture degree relatively high point,the breastfeeding and maternal complications of pregnancy,the lower the percentage of neonatal growth and development better.And after the birth of the newborn,the use of health care for its late growth and development has a role in promoting,with a high value in
