AIM
To produce sex specific percentiles by gestational age for New Zealand infants.
METHODS
Gestational age (completed weeks) and birthweight (10 g multiples) was obtained for all births in New Zealand in 1990 and 1991. Outliers were identified and removed, the data was normalised at each gestational age and percentiles produced.
RESULTS
The percentile charts were produced for gestational ages 24 to 44 weeks by sex of infant. There was an approximate difference of 100 g between male and female birthweight at all gestational ages.
DISCUSSION
These are the first national birthweight percentile charts for New Zealand. As they may vary over time we recommend they be updated every 5 years.
目的
为新西兰婴儿制定按胎龄划分的性别特异性百分位数。
方法
获取了1990年和1991年新西兰所有出生婴儿的胎龄（完整周数）和出生体重（以10克为倍数）。识别并剔除了异常值，对每个胎龄的数据进行了标准化处理并生成了百分位数。
结果
按婴儿性别生成了胎龄24至44周的百分位数图表。在所有胎龄中，男婴和女婴的出生体重大约相差100克。
讨论
这些是新西兰首批全国性的出生体重百分位数图表。由于它们可能随时间变化，我们建议每5年更新一次。
