卡姆登（新泽西州）对少女怀孕期间母亲生长的研究表明，即使少女怀孕时体重增加比成年妇女多，她们所生的婴儿也会相同或更小。此外，研究发现，成长中的青少年所生的婴儿出生时平均体重比已经成年的青少年所生的婴儿轻127克。还记录了生长中的青少年在妊娠晚期血清中铁蛋白和叶酸的浓度显著降低。根据膝高测量仪显示，青春期胎儿出现高收缩期/舒张期（S/D）比的风险增加了两倍以上，这表明母体的生长从胎儿侧影响了胎盘的血管阻力。高S/D比与血流受损和胎儿生长减少有关。卡姆登研究的总体证据表明，即使青少年的饮食与怀孕的成年人相当，体重增加足够，母亲的能量储存如脂肪丰富，仍在生长的母亲和胎儿之间存在竞争。在这种竞争中，母亲的代谢需要优先于胎儿的需要。与与产妇社会阶层相关的风险因素不同，产妇成长有可能在较富裕的青少年中更频繁地发生。
The Camden (New Jersey) Study of maternal growth during adolescent pregnancy has demonstrated that even when adolescents have larger pregnancy weight gains than mature women they bear infants of the same or smaller size. Moreover growing adolescents were found to produce infants who weighed an average of 127 g less at birth than infants of already grown adolescents. Also recorded in growing adolescents were significantly lower third-trimester serum concentrations of the nutrients ferritin and folate. Adolescent gravidas growing as indicated by the Knee Height Measurement Device had more than a two-fold increased risk of a high systolic/diastolic (S/D) ratio suggesting that maternal growth influences the vascular resistance of the placenta from the fetal side. A high S/D ratio is associated with impaired blood flow and diminished fetal growth. Overall evidence from the Camden Study suggests a competition between the still-growing mother and her fetus that is present even when the adolescents diet is comparable to that of a pregnant adult the weight gain is sufficient and maternal energy stores as fat are abundant. In this competition the metabolic needs of the mother take precedence over the needs of the fetus. Unlike risk factors associated with maternal social class maternal growth has the potential to occur more frequently among more affluent adolescents.
