目的 研究不同胎龄新生儿身长胸围相关指数,为胎儿生长发育评价提供参考数据。方法 采用横断面时间段整群抽样实况调查方法,2005-2006年在深圳本院完成了8 357例不同胎龄新生儿体重、身长、坐高、头围、胸围五项生长发育现场测量,制定身长胸围相关指数。结果 1)制定了2005年深圳不同胎龄(孕28~44周)新生儿(男+女、男、女)身长胸围指数(body length-chest circumference index,BCI)、维尔维克指数(Ververck index,VI)、艾里斯曼指数(Elisma index,EI)孕周均数±标准差。三项身长胸围指数都随胎龄增加而增大,显示了胎龄增加人体丰满度和胸廓充实度不断提高。 2)BCI、VI值显示了男低女高的性别差异,揭示了男性丰满度比女性低。EI值孕34周前男性小于女性,孕35周后男性大于女性。3)2005年深圳与1986年中国15城市比较,孕35~43周新生儿BCI值孕周均数有显著提高,存在明显时间段增长变化趋势,差异有统计学意义(P＜0.001)。结论 不同胎龄新生儿 BCI、VI、 EI 孕周均数都随胎龄增加而增大,人体丰满度和胸廓的发育也不断提高;男性丰满度和胸廓的发育低于女性。BCI 指数存在明显的时间段增长变化趋势。

Objective To create body length-chest circumference index of newborns in different gestational age,and to provide a reference data for fetal growth evaluation. Methods By cross-sectional time cluster sampling fact-finding investigation method,the data of 8 357 newborns of Shenzhen Bao'an Maternal and and Child Health Care Hospital (2005-2006) were carried out the site measurements for birth weight,length,sitting height,head and chest circumference,create body length-chest circumference index. Results 1)The gender-specific body length-chest circumference index (BCI),Ververck index (VI) and Elisma index (EI)(x-±s) of newborns in different gestational age (28~44 weeks) were created on Shenzhen City (2005).The BCI,VI and EI were increased with gestational age,indicating that the gestational age increased the body density and enrichment degree.2)BCI and VI of male were lower than those of female.The male fullness and thorax developments were lower than female.EI was higher for female before 34 weeks at birth,but higher for male after 35 weeks.There was an obvious gender-specific difference.3)The plata of Shenzhen (2005 ) compared with Chinese 15 city (1986),the BCI mean of 35~43 weeks newborn had great increased.There was an obvious time period growth trends (P＜0.001). Conclusions The BCI,VI and EI of newborns in different gestational age are increased with gestational age.BCI and VI show differences of male lower than female.There is an obvious gender-specific difference.There is an obvious time period growth trends on BCI of different gestational age newborn of our country.
