男孩的出生体重比女孩的出生体重大约重100克，这似乎在所有人群中都是一致的。目前还没有研究证实这种差异是因为怀男胎的孕妇比怀女胎的孕妇摄入更多的能量或者更有效地利用能量。我们报告的数据支持第一个假设——怀男孩的孕妇能量摄入更高。
The birth weight of boys is about 100 g heavier than the birth weight of girls, and this seems to be consistent across populations. No study, has examined whether the difference is because the pregnant woman has a higher energy intake or more efficient energy utilisation if she is carrying a male embryo than if she is carrying a female embryo. We report data to support the first hypothesis—that the pregnant woman carrying a boy has a higher energy intake.
