Study on height-weight indices in newborns of different gestational ages
摘要
Abstract
ObjectiveTo establish height-weight indices in newborns of different gestational ages and to provide reference data for evaluation of intrauterine fetal growth.MethodsThe weight, height, crown-rump length, head circumference, and chest circumference of 8357 newborns were measured in Maternal and Child Health Care Hospital of Bao'an District of shenzhen between 2005 and 2006, with the method of fact-ifnding investigation with cross-sectional cluster sampling, to establish the height-weight indices in newborns of different gestational ages.ResultsFive gender-speciifc height-weight indices (Quetelet Index, QI; Kaup Index, KI; Rohrer Index, RI; Livi Index, LI; Polock Index, PI) in newborns of different gestational ages (28-44 weeks of gestation) in three different groups (boys+girls, boys, and girls) were established in Shenzhen, China, and were expressed as mean gestational weeks±SD. The ifve indices above all increased with increasing gestational age, and the highest values appeared at 41-43 gestational weeks, suggesting that body density and enrichment degree increased constantly with increasing gestational age. Three indices (QI, KI and PI) were higher in boys than in girls (P<0.05).ConclusionsWith the increasing gestational age, the body density and enrichment degree of newborns increase, and the enrichment degree in boys is better than that in girls.关键词
