早产儿体格发育迟缓及相关因素分析

Analysis of physical growth retardation and related factors in premature infants

目的分析早产儿体格发育迟缓及相关因素。方法选取我院2015年3月~2016年10月收治的158例早产儿患儿为研究对象,按其出生时是否发生宫内生长发育迟缓(IUCR)分为两组,106例患儿无宫内生长发育迟缓(对照组),52例患儿发生宫内生长发育迟缓(观察组)。对比两组早产儿体格发育迟缓情况,并进一步应用Logistic回归分析导致早产儿体格发育迟缓的危险因素。结果在早产儿出院时、纠正胎龄40周时、纠正3个月、6个月龄时,观察组患儿宫外发育迟缓发生率较对照组明显升高;观察组的宫内发育迟缓、达宫内生长水平胎龄、住院天数与对照组比较明显升高,宫外发育迟缓组的出生体重与非宫外发育迟缓组比较明显降低;采用Logistic回归分析对上述指标进行统计学处理,发现影响早产儿体格发育迟缓的危险因素为宫内发育迟缓、出生体重、达宫内生长水平胎龄、住院天数,差异有统计学意义(P<0.05)。结论在早产儿体格发育迟缓中,导致其发生的因素有很多,如宫内发育迟缓、出生体重、达宫内生长水平胎龄、住院天数。

Objective To analyze the physical growth retardation and related factors of premature infants.Methods From March 2015 to October 2016,158 cases of premature infants who treated in our hospital were selected as research objects,and divided into two groups according to their birth whether intrauterine growth retardation(IUCR).No intrauterine growth retardation occurred in 106 children(control group),and intrauterine growth retardation occurred in 52 cases(observation group).Premature infants physical development of two groups were compared,and Logistic regression analysis was further applied to analyze the risk factors for premature infants'physical growth retardation.Results The incidences of extrauterine growth retardation in the observation group were significantly higher than those of the control group when the premature infants were discharged from hospital,corrected 40 weeks of gestational age,corrected 3 months of age,and corrected 6 months of age.In the observation group,the intrauterine growth retardation,the age of the intrauterine growth level and days of hospitalization were significantly higher than those of the control group.The birth weight in the group of extrauterine development retardation group was significantly lower than that of the non ectopic development retardation group.The Logistic regression analysis was used to analyze the above indexes,and found that the risk factors affecting the growth retardation of premature infants were intrauterine growth retardation,birth weight,age of intrauterine growth and days of hospitalization,and the difference was statistically significant(P<0.05).Conclusion There are many factors such as intrauterine growth retardation,birth weight,age of intrauterine growth,and days of hospitalization.
