OBJECTIVE
Our aim was to evaluate the effect of emigration on fetal birth weight (BW) in a group of pregnant women coming from the Indian subcontinent.
METHODS
This was a retrospective study in a mixed population of pregnant women from the Indian subcontinent that either moved to Europe or stayed in their original countries. The influence of emigration along with several pregnancy characteristics: GA at delivery, fetal gender, maternal age, height, weight, body mass index (BMI) and parity on BW was evaluated by means of multivariable linear regression analysis.
RESULTS
According to European standards, babies born to Indo-Pakistan emigrants and babies born to women staying in the Indian subcontinent were similarly small (BW centile 30± 29 and 30.1 ± 28, <0.68). Multivariable regression demonstrated that emigration by itself did not exert a direct influence on BW ( = 0.27), being BMI and gestational age at delivery the true determinants of BW (<0.0001).
CONCLUSIONS
Maternal BMI is the most relevant parameter affecting fetal growth regardless of the place of residence.
目的
我们的目的是评估移民对一群来自印度次大陆的孕妇所产胎儿出生体重（BW）的影响。
方法
这是一项针对来自印度次大陆的混合孕妇群体的回顾性研究，这些孕妇要么移居欧洲，要么留在原籍国。通过多变量线性回归分析评估移民以及几个妊娠特征：分娩时的孕周（GA）、胎儿性别、母亲年龄、身高、体重、体重指数（BMI）和产次对出生体重的影响。
结果
根据欧洲标准，印度 - 巴基斯坦移民所生婴儿和留在印度次大陆的妇女所生婴儿同样偏小（出生体重百分位数分别为30±29和30.1±28，<0.68）。多变量回归表明，移民本身对出生体重没有直接影响（β = 0.27），体重指数和分娩时的孕周才是出生体重的真正决定因素（<0.0001）。
结论
无论居住地点如何，母亲的体重指数是影响胎儿生长的最相关参数。
