Growth of arm muscle, fat and water areas were evaluated longitudinally in a prospective study in 81 infants from birth to the age of 12 months. The percentage of arm fat area v the cross sectional upper arm area increased at the age of 15 days with a peak peak at the age of 6 months while arm muscle area increased progressively throughout the year. As arm water area represented only 1% of cross sectional upper arm area, calculations of arm fat and muscle areas can be carried out from measurements of mid arm circumference and tricipital skinfold at 15 seconds. Percentiles are presented for the upper arm fat and muscle areas, which can be used as index for the infants' nutritional state.
在一项前瞻性研究中,对81名婴儿从出生到12个月大时的手臂肌肉、脂肪和水分区域的生长情况进行了纵向评估。手臂脂肪面积与上臂横截面积的百分比在15天时增加,在6个月时达到峰值,而手臂肌肉面积则在全年逐渐增加。由于手臂水分面积仅占上臂横截面积的1%,因此可以在15秒时通过测量上臂中部周长和三头肌皮褶厚度来计算手臂脂肪和肌肉面积。文中给出了上臂脂肪和肌肉面积的百分位数,可作为婴儿营养状况的指标。
