An in-depth discussion of national and local statistics regarding teenage and adolescent pregnancy and the developmental issues involved opens this analysis. Problems and adverse consequences of adolescent pregnancy in an urban setting are explored using a city-wide random sample of adolescent births.

Johnson); (2) "The Johns Hopkins Adolescent Pregnancy Program (HAC)" (Services and Evaluation); (3) "Medical Management of Pregnant Adolescents" (John T. Repke); (4) "Nutrition and the Pregnant Adolescent" (John T.
