摘要
本文对中国15城市24150例胎龄从28～44周活产新生儿有关身长体重的五项指数的各自变化规律及相互之间的内在联系进行了研究，其值均随胎龄增加而增大，足月新生儿存在男女性别差异，其中劳雷尔指数（RI）和利比指数（LI）女＞男（P＜0．01）。该五项指数均可综合评价新生儿全身营养状况，体型及体格发育的匀称度，从而弥补了单项指标之不足，本研究建立了我国不同胎龄新生儿身体指数的正常参考值。
We analysed five body Length-Weight indexes in 24, 150 live singleton who were born at gestaional ages 28 to 44 weeks in 15 cities in China. We studied the variation of each index and the connection among them too. The results showed that the values of all the indexes increased with gestational age and that there were marked differences between male and female in neonates of full-term, including RI and LI whose values in female were larger than those in male (P<0.01). The five indexes may be uged to comprehensively assess the physical development,nutritional status and body form of infants at birth. The research established the references for body indexes of newborns in our country
