早产低出生体重儿喂养指数及影响因素分析

Feeding index and its influencing factors of preterm and low birth weight infants

目的探讨早产低出生体重儿喂养指数及影响因素,为改善其喂养与营养状况提供参考依据。方法选取2023年6月—2024年3月在北京大学第一医院宁夏妇女儿童医院儿童保健中心健康检查的100例矫正6~24月龄早产低出生体重儿为病例组,同期正常健康检查的108例婴幼儿为对照组,对喂养指数进行比较分析。结果早产低出生体重儿喂养指数总评分为10.56±4.77。6~8月龄组、9~11月龄组及总评分均低于对照组,且6~8月龄组差异有统计学意义(P<0.05)。非条件Logistic回归分析显示,喂养指数的主要促进因素为母乳喂养(OR=2.864,95%CI:1.023~8.015,P=0.045)、配方奶时间(OR=2.185,95%CI:1.138~4.195,P=0.019)、月龄(OR=2.426,95%CI:1.276~4.612,P=0.007)。结论早产低出生体重儿喂养指数较低,需采取相关干预措施。

Objective To explore the feeding index and influencing factors in preterm low birth weight infants,in order to provide reference for improving their feeding and nutritional status.Methods A total of 100preterm low birth weight infants at the corrected age of 6to 24 months,who underwent health check-ups at the PKUFH-Ningxia Women and Children′s Hospital between June 2023and March 2024,were selected as the case group.Meanwhile,108healthy infants and toddlers undergoing routine check-ups during the same period were selected as the control group.The feeding indices were compared and analyzed between the two groups.Results The overall feeding index score for preterm low birth weight infants was 10.56±4.77.Scores for the 6-8month age group,the 9-11month age group,and the overall score in the preterm low birth weight infants were lower than those in the control group,but only the difference in the 6-8month age group was statistically significant(P<0.05).Unconditional Logistic regression analysis showed that the main facilitators of the feeding index were breastfeeding(OR=2.864,95%CI:1.023-8.015,P=0.045),formula feeding duration(OR=2.185,95%CI:1.138-4.195,P=0.019),and age in months(OR=2.426,95%CI:1.276-4.612,P=0.007).Conclusion The feeding index in preterm low birth weight infants is relatively low,indicating the need for relevant intervention measures.
