This Kids Count report presents current information on adolescent pregnancy rates in Missouri. Part 1, "Overview of Adolescent Pregnancy in Missouri," discusses the changing pregnancy, abortion, and birth rates for 15- to 19-year-old adolescents, racial differences in pregnancy risk, regional differences suggesting a link between pregnancy and poverty, and the preponderance of adolescent births in urban counties. Part 2, "Risk Factors for Adolescent Pregnancy," discusses increasing teen sexual activity and contraceptive use; describes how the risk factors of poverty, high risk behavior, poor academic skills, media portrayal of sexuality, and sexual abuse can provide a basis for preventive strategies; and points out that positive relationships with family and church can reduce risk. Part 3, "Consequences of Adolescent Childbearing," illustrates the health, economic, and educational risks faced by adolescent mothers; discusses the disadvantages for children of teen parents; and presents the economic costs of teen pregnancy. Part 4, "Principles and Strategies to Reduce Adolescent Pregnancy," advocates programs targeting adolescent sexuality, contraceptive use, and pregnant or parenting teens, in addition to holistic programs addressing the underlying issues of poverty, unemployment, and school success. Part 5, "Selected Missouri Programs That Are Making a Difference," reveals that programs for pregnant or parenting teens were more common than prevention programs and that few programs had conducted outcome evaluations. Part 5 also describes several intervention programs. Appended are Missouri program contact persons, data notes, and acknowledgments. (Contains 26 references.) (KDFB)
