背景：某些移民母亲的新生儿出生时比国内出生的母亲的新生儿小。当代，这些新生儿的人口来源的百分位数曲线是缺乏的，因为他们的风险被误分类为太小或太大，而不是定制的出生体重currents.Methods：我们完成了一项以人口为基础的研究，从2002年至2007年的安大略的766 688单胎活产。生成了男性和女性的平滑出生体重百分位数曲线，按母亲世界出生地区分类：加拿大（63.5%）、欧洲/西方国家（7.6%）、非洲/加勒比海（4.9%）、中东/北非（3.4%）、拉丁美洲（3.4%）、东亚/太平洋（8.1%）和南亚（9.2%）。我们确定了将婴儿错误分类为小于胎龄儿的可能性，（=体重的第90百分位数）与一个特定的产妇世界原产地的曲线。结果：除欧洲/西方国家外，世界各地区母亲在妊娠特定的第10、50和90胎所生的足月婴儿出生体重明显较低，与那些出生在哥伦比亚的母亲的婴儿相比。例如，对于妊娠40周出生的南亚婴儿，男性第10百分位数的绝对差异为198 g（95% CI 183至212），女性为170 g（95% CI 161至179）。控制母亲年龄和产次，南亚男性被误分类为小于胎龄儿的比值比为2.60（95%CI 2.53至2.68），相当于每1000名新生儿中约有116名;南亚女性的OR为2.41（95%CI 2.34至2.48），相当于每1000名新生儿中约有106名。大胎龄将错过约61每1000名男性和57每1000名女性南亚新生儿，如果传统的，而不是种族特异性的出生体重curves were used.Conclusions：出生体重曲线需要修改的新生儿的移民母亲来自非欧洲/西方国家。
Background: Newborns of certain immigrant mothers are smaller at birth than those of domestically born mothers. Contemporary, population-derived percentile curves for these newborns are lacking, as are estimates of their risk of being misclassified as too small or too large using conventional rather than tailored birth weight curves.Methods: We completed a population-based study of 766 688 singleton live births in Ontario from 2002 to 2007. Smoothed birth weight percentile curves were generated for males and females, categorized by maternal world region of birth: Canada (63.5%), Europe/Western nations (7.6%), Africa/Caribbean (4.9%), Middle East/North Africa (3.4%), Latin America (3.4%), East Asia/Pacific (8.1%), and South Asia (9.2%). We determined the likelihood of misclassifying an infant as small for gestational age (= 90th percentile for weight) on a Canadian-born maternal curve versus one specific to maternal world region of origin.Results: Significantly lower birth weights were seen at gestation-specific 10th, 50th, and 90th percentiles among term infants born to mothers from each world region, with the exception of Europe/Western nations, compared with those for infants of Canadian-born mothers. For example, for South Asian babies born at 40 weeks' gestation, the absolute difference at the 10th percentile was 198 g (95% CI 183 to 212) for males and 170 g (95% CI 161 to 179) for females. Controlling for maternal age and parity, South Asian males had an odds ratio of 2.60 (95% CI 2.53 to 2.68) of being misclassified as small for gestational age, equivalent to approximately 116 in 1000 newborns; for South Asian females the OR was 2.41 (95% CI 2.34 to 2.48), equivalent to approximately 106 per 1000 newborns. Large for gestational age would be missed in approximately 61 per 1000 male and 57 per 1000 female South Asian newborns if conventional rather than ethnicity-specific birth weight curves were used.Conclusions: Birth weight curves need to be modified for newborns of immigrant mothers originating from non-European/Western nations.
