This is an overview of two related reports that describe, respectively, recent research findings regarding adolescent sexual and fertility behavior and intervention programs aimed at reducing adolescent pregnancy and parenthood in the United States. The reports were commissioned by the Assistant Secretary for Planning and Evaluation, U.S. Department of Health and Human Services. The reports emphasize original studies conducted in the late 1980s and 1990s that have high research standards with respect to study design, sampling, and measurement, and that employ multivariate analyses. Detailed explanations and elaborations which can not be included here because of space limitations are provided in the individual reports: "Adolescent Sex, Contraception and Childbearing: A Review of Recent Research" and "Adolescent Pregnancy Programs: Interventions and Evaluations." Copies of the reports are available from Child Trends, Inc.
