直到最近，人们普遍认为，在年轻孕妇中观察到的少量身材生长不太可能具有临床意义，不会改变母亲的营养状况或威胁胎儿的生长。我们表明，这种信念反映了有关生长的不完整信息以及研究人员使用不适当的测量技术。我们使用的插图主要来自卡姆登研究，这是一项针对青少年怀孕期间营养和生长的对照前瞻性研究。怀孕期间母亲的生长很普遍，并且与妊娠期体重增加有关。在产后期，它与三头肌皮褶、手臂脂肪面积和体重保留的增加有关，所有这些都发生在与怀孕、未生长的青少年和成熟女性相当的热量摄入量下。与仍在继续研究的妊娠不同，哺乳期母亲生长的后遗症实际上尚未得到研究。
Until recently, it was widely accepted that the small amount of statural growth observed in young gravidas was unlikely to be clinically significant, to alter maternal nutritional status, or to threaten fetal growth. We show that this belief reflects incomplete information about growth and the use of inappropriate measuring techniques by investigators. We have done this using illustrations drawn primarily from the Camden Study, a controlled, prospective study of nutrition and growth during adolescent pregnancy. Maternal growth during pregnancy is prevalent and associated with increased gestational weight gain. In the postpartum period it is associated with increased triceps skinfolds, arm fat area and weight retention, all of which occur at caloric intakes comparable with those of pregnant, non-growing adolescents and mature women. Unlike pregnancy where research is continuing, the sequelae of maternal growth during lactation are virtually unstudied.
