Pelvic dimensions by x-ray of 282 pregnant adolescents and 181 adult women were compared to ascertain if the pelvis of the adolescent was smaller and contracted with greater frequency. The majority of 10 pelvic dimensions for black and white adolescents were significantly smaller or contracted with significantly greater frequency. The pattern of signifcant differences suggests that the adolescent pelvis has yet to mature fully by age 16. As a consequence of physiologic events during puberty, described by several authors, the adolescent pelvis grows at an accelerated rate and typically changes from an anthropoid to a gynecoid configuration. Caution must be taken in applying these results since pelvic size is not synonymous with obstetric outcome.
对282名怀孕青少年和181名成年女性进行骨盆X光测量，以确定青少年的骨盆是否更小且收缩频率更高。黑人与白人青少年的10项骨盆测量指标中，大多数显著更小或收缩频率显著更高。这些显著差异表明，16岁时青少年骨盆尚未完全成熟。几位作者描述了青春期的生理变化，青春期时青少年骨盆生长加速，通常从类人猿型转变为女性型。应用这些结果时必须谨慎，因为骨盆大小并不等同于产科结局。
