Offspring of teenage mothers: congenital malformations, low birth weights and other findings.

Teenage mothers were found to have congenitally malformed infants with a significantly higher frequency when compared to a published control population. Low birth weight and perinatal death were common among the infants of mothers 17 and younger. No chromosomal anomalies were found among the infants of this population, but this result does not unequivocally rule out an increased frequency of these disorders.
