目的：介绍澳大利亚按胎龄出生的男女单胎婴儿的最新全国出生体重百分位数。设计和背景：对澳大利亚1998年至2007年间的253万单胎活产婴儿进行的横断面人口研究。主要结局指标：按胎龄和性别划分的出生体重百分位数。结果：1998年至2007年间，澳大利亚妇女共生下2539237名活产单胎婴儿。其中，2 537 627名孕妇的胎龄在20至44周之间，并有性别和出生体重数据。在排除了8986名出生体重异常的婴儿后，按性别和胎龄列出了2 528 641名新生儿的出生体重百分位数。自1999年澳大利亚公布之前的出生体重百分位数以来，足月婴儿的出生体重中位数在男孩0到25克之间增加，女孩在5到45克之间增加。结论：自1991-1994年以来，无论男女和大多数胎龄婴儿的出生体重百分位数仅略有增加。这些国家百分位数为临床医生和研究人员评估出生体重提供了当前澳大利亚的参考。
Objective: To present updated national birthweight percentiles by gestational age for male and female singleton infants born in Australia.Design and setting: Cross-sectional population-based study of 2.53 million singleton live births in Australia between 1998 and 2007.Main outcome measures: Birthweight percentiles by gestational age and sex.Results: Between 1998 and 2007, women in Australia gave birth to 2 539 237 live singleton infants. Of these, 2 537 627 had a gestational age between 20 and 44 weeks, and sex and birthweight data were available. Birthweight percentiles are presented by sex and gestational age for a total of 2 528 641 births, after excluding 8986 infants with outlying birthweights. Since the publication of the previous Australian birthweight percentiles in 1999, median birthweight for term babies has increased between 0 and 25 g for boys and between 5 g and 45 g for girls.Conclusions: There has been only a small increase in birthweight percentiles for babies of both sexes and most gestational ages since 1991-1994. These national percentiles provide a current Australian reference for clinicians and researchers assessing weight at birth.
