摘　　要：目的验证张路指数(ZLI)在新生儿体格发育评价中的应用。方法对413例新生儿测量体质量、头围、身长,根据ZLI公式计算ZLI值,并通过31例小于胎龄(SGA)儿、65例大于胎龄(LGA)儿、317例适于胎龄(AGA)儿首次测量的原始数据对ZLI与惯用胎龄-体质量法进行验证比较。结果1.ZLI与胎龄-体质量法比较,灵敏度高于全国验证结果,有统计学差异(χ2=6.45 P<0.05),特异度、总符合率与全国验证结果比较,无统计学差异(χ2=2.38,0.22 P均>0.05);2.怀化市新生儿ZLI平均值高于全国参考值,有统计学差异(P<0.01);3.ZLI随胎龄及生后日龄增大而增加,有统计学差异(P<0.01);4.ZLI纵向累积增长率SGA儿最大,LGA儿最小,有统计学差异(P<0.05);5.超重或肥胖发生率LGA儿最大,SGA儿在各时段均为0,有统计学差异(P<0.01)。结论ZLI是一个综合评价胎儿期及新生儿期体格发育水平的指数。Objective To validate the practical value of zhang - lu index（ZLI） in evaluating the physical growth of neonates. Methods Collecting the data of body weight, height and head circumference from 413 neonates, the results of ZLI were calculated according to the ZLI expression, then through the original date coming from 31 small for gestational age（SGA）, 65 large for gestational age（LGA） and 317 appropriate for gestational age（AGA ）, ZLI was compared with the conventional method of body weight for gestational age. Results 1. Compared with the method of body weight for gestational age, the sensitivity was higher than the result validated by the nation. The difference was significantly（ P 〈 0.05）. The specificity was lower than the result validated by the nation. The differences of the total compatible rate between the nation and Huaihua had no significance（ P 〉 0.05）. 2. The results of ZLI of neonates in Huaihua city were larger than the reference given by the national of neonatal scientific research associate;The differences were significantly（ P 〈 0.01 ）. 3. ZLI increases along with the gestational age and the daily age,The differences were significantly（ P 〈 0.01 ）. 4. The largest accumulating increasing rate of ZLI in vertical orientation of the different neonates was SGA, next was AGA, and LGA was the smallest one;The differences among 3 groups were significantly（P 〈 0.01 ）. 5. The incidence of overweight or obesity in LGA was higher than that of AGA, while it rarely occurred in SGA;The differences among 3 groups were significantly（ P 〈 0.01 ）. Conclusion ZLI is a better indicator for evaluating the growth of fetal and neonatal period.
