One Thousand singleton neonates, between 28 and 44 weeks of estimated gestational age (EGA) were measured within 48 hours of their birth for upper mid-arm circumference (MAC), head circumference (HC) and birth weight (BW). Regression analysis was used to draw standard curves for MAC versus EGA and mid-arm circumference/head circumference ratio (MAC/HC) versus EGA. Correlation coefficients were 0.961 for MAC versus EGA and 0.889 for MAC/HC versus EGA (p less than 0.001). MAC, MAC/HC and HC were also highly correlated with birth weight (p less than 0.001). These standard curves make available a discriminating method for evaluation of intra-uterine growth and a non-invasive technique for following somatic protein status in growing preterm infants.
对1000名单胎新生儿在出生后48小时内进行测量，这些新生儿的估计孕周（EGA）在28至44周之间，测量指标包括上臂中部周长（MAC）、头围（HC）和出生体重（BW）。采用回归分析绘制MAC与EGA以及上臂中部周长/头围比（MAC/HC）与EGA的标准曲线。MAC与EGA的相关系数为0.961，MAC/HC与EGA的相关系数为0.889（p<0.001）。MAC、MAC/HC和HC与出生体重也高度相关（p<0.001）。这些标准曲线为评估宫内生长提供了一种鉴别方法，以及一种用于跟踪早产婴儿体蛋白状态的非侵入性技术。
