1110例新生儿皮下脂肪厚度分析

ANALISIS ON THE SUBCUTANEOUS FAT THICKNESS OF 1110 NEWBORNS

1110例新生儿皮下脂肪调查结果,腹壁、颊部及大腿的厚度,城区足月初生儿分别为0.41、1.10及0.78;郊区分别为0.38、1.04及0.73。晚期新生儿分别为0.55、1.49及1.02。城区明显厚于郊区,并随着体重身长的增长而增厚。小胎龄时随着胎龄的增大而增厚,约40周达高峰,此后又渐变薄。这些变化与孕妇营养,自然生长发育及胎盘功能有关。新生儿皮下脂肪厚度不及婴幼儿的1/2。基于这一特点,新生儿营养不良应有独自的诊断标准,腹壁皮下脂肪厚度0.28可作为诊断条件之一。

Through investigatng, The author reported that the subcutaneous fat thickness of full term newborns in abdomen, cheek and thigh are 0. 41、1. 10 and 0. 73 Cm respectively in the city proper 0. 38、1.04 and 0. 73 respectively in the suburb; That the subcutaneous fat thickness of later period newborn in abdomen, cheek and thigh are 0. 55、 1. 49 and 1. 02 respectively; That the subcutaneous fat thickness is thicker in the city than in the suburb. With increasing of the age in early period of newborn, the weighter and higher of body, the thicker of the subcutaneous fat thickness, it reachs the top of thickness in about 40 weeks of age. It becomes thiner afterward. These variations of thickness related to pregnant nutrition, nature growth and placenta' s functions. These rusults indicate the newborn subcutaneous fat thickness is 1/2 times less than infant. This characteristc provided a unigue di-agnore standard for newborn malnutrition. That newborn subcutaneous fat thickness in abdomen is 0. 28 cm may be one of diagnostic qualifications of newborn malnutrition.
