摘　　要：目的　建立适于胎龄（ＡＧＡ） 新生儿体格发育指数的纵向监测参考值，并探讨其使用价值。　方法　用计算机演算１ ７５７ 例ＡＧＡ 新生儿的５ 项身体指数，即ＱｕｅｔｅｌｅｔＩｎｄｅｘ（ＱＩ） 、Ｒｏｈｒｅｒ Ｉｎｄｅｘ（ＲＩ） 、身长顶臀长指数（ＢＲＩ） 、身长／ 头围（ＢＬ／ＨＣ） 、中臂围／ 头围（ ＭＡＣ／ＨＣ） 比值。　结果　新生儿期内ＱＩ、ＲＩ、ＭＡＣ／ＨＣ 随日龄增大而增大，反映了新生儿营养状态的变化，ＢＬ／ＨＣ 显示新生儿期身长与头围为同步增长，ＢＲＬ 则显示早产儿在新生儿期内的追赶生长以上身增长为主。　结论　身体指数作为新生儿体格发育综合评价指标，利用其纵向监测值可动态观察新生儿在各时段的营养状态、体格发育的匀称度，为优生提供参考指标。为此我们提供了５ 项指数的正常均值、标准差及百分位数，便于临床应用及流行病学调查时直接查对。Objective To study the longitudinal survey of body indices of chinese newborns appropriate for gestational age (AGA),several pertinent parameters and its useful value. Methods Five body indices of a total of 1 757 AGA neonates converged from 12 cities in China were caculated with computer,which were the gestational maturation,the Quetelet Index(QI),Rohrer Index (RI),Recumbent length Croun Rump length Index(BRI),Recumbent length/Head circumference(BL/HC),Mid-Arm circumference/Head circumference(MAC/HC) ration;and the relative longitudinal regularity,variation,percentile of each index. Results The increase of QI,RI,and MAC/HC ratio along with the infants growth within the lst month reflect the change of nutritional state of newborns.On the other hand,BL/HC ratio shows the synchronous rise of boody length and head circumference,BRI reflects that the premature AGA neonates in the first month are catching up with the term infants' growth mainly the upper part of boody. Coonclusion As the indicator for the comprehensive evaluation of neonates' physical growth,the data of boody indices in the present study can be utilized to observe dynamicelly nutritional status,proportion of body parts and somatotype of newborns,thus,providing several references for the eugenics.Both mean value and standerd deviation,as well as percentile of five indices were demonstrated in order to check the list we provided for the clinical application and epidemiologcal investigation.
