The purpose of this study was to obtain demographic, contraceptive, pregnancy, and pregnancy-resolution information on 725 teenage girls aged 18 years or younger who were enrolled in the postnatal follow-up component of the Johns Hopkins Adolescent Pregnancy Program during the years 1976 to 1982. Since in many cases pregnancy data were obtained retrospectively, the actual years during which deliveries are recorded span the period of 1970 to 1982. Demographic information on the father of the baby was also obtained.
