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。
The subcutaneous fat of 1110 newborns, abdominal wall, cheek and thigh thickness, urban full-term newborns were 0.41, 1.10 and 0.78; the suburbs were 0.38,1.04 and 0.73 respectively. Late neonates were 0.55, 1.49 and 1.02 respectively. The city is significantly thicker than the suburbs and thickens as the body weight grows. Small gestational age increases with age and thickening, reached a peak of about 40 weeks, and then gradually thinning. These changes and pregnant women nutrition, natural growth and placental function. Subcutaneous fat in newborns less than half the thickness of infants. Based on this feature, neonatal malnutrition should have a separate diagnostic criteria, the subcutaneous fat thickness of 0.28 can be used as one of the diagnostic criteria.
