Skeletal maturity and growth of adolescent mothers: relationship to pregnancy outcome.
The purpose of this study was to evaluate the relationship between postpartum maternal bone age and the incidence of obstetric and neonatal complications in adolescent pregnancies. Bone age determinations were obtained on 93 poor, black 12- through 18-year-old adolescents during the puerperium. Results showed maternal bone ages ranging from 15 to 18 years; bone age was less than 18 years in 64 (68.8%) of the 93 adolescent mothers we studied. Maternal bone age correlated significantly with maternal chronologic age (r = 0.70) and prepregnant body size (r = 0.25) but did not correlate with total maternal weight gain and growth during pregnancy, the incidence of obstetric and neonatal complications, or infant birth weight and gestational age. Our findings suggest that many young, pregnant adolescents have the potential to grow during and after pregnancy, but do not support the hypothesis that ongoing maternal growth is an obstetric risk factor during adolescence.
