背景资料：与使用辅助生殖技术有关的低出生体重风险增加，主要原因是与这种技术有关的多胎妊娠率较高。然而，目前还不确定是否使用辅助生殖技术受孕的单胎婴儿也可能比自然受孕的婴儿有更高的低出生体重风险。方法：我们使用基于人群的数据比较低出生体重（小于/等于2500 g）和极低出生体重（
Background: The increased risk of low birth weight associated with the use of assisted reproductive technology has been attributed largely to the higher rate of multiple gestations associated with such technology. It is uncertain, however, whether singleton infants conceived with the use of assisted reproductive technology may also have a higher risk of low birth weight than those who are conceived spontaneously.Methods: We used population-based data to compare the rates of low birth weight (lessthan/equal 2500 g) and very low birth weight (
