适于胎龄新生儿身体指数纵向监测的意义探讨

建立适于胎龄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１７５７例ＡＧＡ新生儿的５项身体指数，即ＱｕｅｔｅｌｅｔＩｎｄｅｘ（ＱＩ）、ＲｏｈｒｅｒＩｎｄｅｘ（ＲＩ）、身长顶臂长指数、身长／头围、中臂围／头围比值。

Signficance of the Longitudinal Study of AGA Neonate Body Indices.

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.
