The goals, grantmaking strategies, and interests of the Mott Foundation with regard to identifying problems and developing programs for adolescent women are reviewed in a brief introduction. Four articles address various aspects of the problem of teenage pregnancy. The title article provides a review of recent statistics on a decline in the teen birthrate, pointing out that there is still an enormous problem of teen pregnancies. Of special concern is the continuing increase in the number of babies born outside marriage to teen mothers. No single approach will reduce pregnancy rates among all groups of teenagers. The influence of several distinct and complex issues is summarized. Two articles, "The Carrera Model: A Program for Youth 'At Promise,' Not 'At Risk'" and "Training and Evaluating Keys to Future for Carrera Model," highlight a holistic, adolescent pregnancy prevention initiative of the New York City-based Children's Aid Society, a long-term comprehensive program for adolescents with many deficits in their lives. Replications of the program are reported. The final article, "Innovative Programs Address Sociocultural Barriers," examines Mott-supported projects that deal with other aspects of the teen pregnancy issue. (EMK)
