As shown in 79,000 girls and women participating in four different surveys, low body weight (less than or equal to 47.2 kg) does not prevent the attainment of menarche, conception, or even repeated conceptions. Indeed, low body weight is especially common in early maturing girls and in Puerto Ricans and Mexican-Americans. From these data, the concept of a "critical weight" for menarche is difficult to substantiate, although low body weight does have nutritional implications and is the second most important factor in regulating fetal growth.
在参与四项不同调查的79000名女孩和妇女中,低体重(小于或等于47.2千克)并不会妨碍月经初潮、受孕,甚至多次受孕。事实上,低体重在早熟女孩以及波多黎各人和墨西哥裔美国人中尤为常见。从这些数据来看,月经初潮“临界体重”的概念难以得到证实,尽管低体重确实存在营养方面的影响,并且是调节胎儿生长的第二重要因素。
