摘　　要：目的分析早产低出生体重儿与足月儿身体成分差异。方法选取2021年8月-2022年2月柳州市妇幼保健院出生的早产低出生体重儿51例及足月出生儿51例,分为早产低体重儿组及足月儿组。采用生物电阻抗法分别测量相位角、脂肪、人体总水量、细胞外液、细胞内液、干瘦肉、身体瘦肉、体重指数、营养指数、预测指数、骨骼肌肉群等,比较不同时间两组婴儿人体成分差异。结果出生后第1天,足月儿组体重指数、总水分、干瘦肉、基础代谢率、体细胞质量及相位角检测值均高于早产低体重儿组(P<0.05),脂肪、骨骼肌肉群含量低于早产低体重新生儿(P<0.05);出生后第2、3天,足月儿组体重指数、总水分、干瘦肉、基础代谢率、体细胞质量及相位角检测值均高于早产低体重儿组(P<0.05);两组脂肪含量、骨骼肌肉群比较,差异无统计学意义(P>0.05)。结论早产低体重新生儿体重指数、总水分、干瘦肉、基础代谢率、体细胞质量及相位角与足月新生儿差异明显,脂肪及骨骼肌肉群含量在早产低体重儿与足月儿中是否存在差异仍需大样本研究进一步验证。Objective To analyze the body composition difference between preterm low birth weight infant and term infant.Methods A total of 51 premature low birth weight infants and 51 term infants born in Liuzhou Maternal and Child Healthcare Hospital from August 2021 to February 2022 were selected and divided into premature low birth weight infants group and term infants group.The phase angle,fat,total body water,extracellular fluid,intracellular fluid,dry lean meat,body lean meat,body mass index,nutritional index,predictive index and skeletal muscle group were measured by bioelectrical impedance method,and the differences of body composition between the two groups at different times were compared.Results On the first day after birth,the body mass index,total body water,dry lean meat,basal metabolic rate,somatic cell mass and phase angle of term infants group were higher than those of premature low birth weight infants group(P<0.05),and the contents of fat and skeletal muscle group were lower than those of premature low birth weight infants group(P<0.05).On the 2nd and 3rd day after birth,the body mass index,total body water,dry lean meat,basal metabolic rate,somatic cell mass and phase angle detection values of the term infants group were higher than those of the premature low birth weight infants group(P<0.05),while there was no significant difference in fat content and skeletal muscle group between the two groups(P>0.05).Conclusion The body mass index,total moisture,dry lean meat,basal metabolic rate,somatic cell mass and phase angle of preterm low birth weight infants are significantly different from those of term infants.Whether there are differences in fat and skeletal muscle group content between preterm low birth weight infants and term infants still needs to be further verified by large sample studies.
