目的探索早产儿生后半年体重增长速率的影响因素,为提高早产儿生命质量提供理论依据。方法追踪随访安徽省妇幼保健院高危儿随访中心自2012-2014年随访的174例早产儿至生后6个月,随访周期为每月随访一次,主要监测指标为体重、身长和头围;同时,收集胎龄、出生体重、合并症、高危因素、家庭情况等基线资料。采用多元回归分析方法分析影响早产儿体重增长速率的影响因素。结果单因素方差分析显示,喂养方式、性别、小于胎龄儿、早产分类存在组间差异,且有统计学意义(P<0.05),出生体重、分娩年龄、早产合并症、妊娠合并症不同组间并未发现差异(P>0.05)。多元回归分析表明,胎龄、小于胎龄儿、性别和喂养方式是影响早产儿体重增长速率的主要因素。结论积极个性化的营养方案对于提高早产儿体重增长速率意义深远。
Objective To explore the influencing factors of the rate of weight gain in the first half of premature infants and to provide theoretical basis for improving the quality of life of premature infants. Methods Follow-up Follow-up 174 high-risk children follow-up centers in Anhui MCH center from 174 preterm infants to 6 months after follow-up were followed up every month. The main monitoring indicators were body weight, length and head circumference. , Collecting baseline data such as gestational age, birth weight, comorbidity, risk factors, family status. Multiple regression analysis was used to analyze the influencing factors on the rate of weight gain in preterm infants. Results One-way analysis of variance showed that there was a significant difference in terms of feeding patterns, sex, gestational age, and preterm birth among the groups, with statistical significance (P <0.05), birth weight, age of childbirth, preterm birth complications, No difference was found between the two groups (P> 0.05). Multivariate regression analysis showed that gestational age, gestational age, gender and feeding patterns were the main factors affecting the rate of weight gain in preterm infants. Conclusion The positive and personalized nutrition plan has far-reaching significance for increasing the rate of weight gain in preterm infants.
