Abstract: 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.
