title: Low 'gynecologic': an obstetric risk factor.
abstract: The records of patients who were 17 years of age and younger at delivery were reviewed in order to ascertain whether or not a patient's gynecologic age (GA, defined as chronologic age minus age at menarche) independently relates to pregnancy risk. Low GA in a pregnant adolescent increases the chance of delivery of a low--birth weight infant. However, pre-eclampsia and other pregnancy complications studied were not related GA.
