Zhang- Lu Index for Comprehensive Evaluation of the Physical Growth of Newborns

【Objective】 To establish a new index for comprehensive evaluation of physical growth of neonates. 【Methods】 Zhang-LuIndex(ZLI)： was computerized with data of body height, body weight and head circumference collected from 1 341 full-term AGA neonates. This index as well as other 10 boby indices were compared to theconventional body weight for gestational age based on data coming from 144 SGA, 160 LGA and 75 AGA neonates. 【Results】Differences among ～31, ～32, ～33 gestational weeks and between ～34 and ～35 gestational weeks were silnificant respectively( P< 0.05). After birth,ZLI increases along with the daily age. The differences among the daily age in ～3days, ～7days, ～14days, ～28days,and ～60days were also significant (P<0.01). Compared to the method of body weight for gestational age, and other 10body indices the sensitivity, specificity, loss diagnositic rate, false diagnositic rate as well as the total compatible rate for ZLI were70 %,75 %, 30%, 25 % and 73 % respectively. The normal values were fluctuated in small range (x + s, 1.00 + 0.06) which in-eluded more parmeters (height, weight and head circumference) were easy remembered. 【Conclusions】 ZLI is a better indicatorfor comprehensively evaluating the growth of intrauterine and in posnatal 2 months of life.
