More than 1 million teenage girls in the United States become pregnant each year; nearly half give birth. Why do these young people, who are hardly more than children themselves, become parents? This volume reviews in detail the trends in and consequences of teenage sexual behavior and offers thoughtful insights on the issues of sexual initiation, contraception, pregnancy, abortion, adoption, and the well-being of adolescent families. It provides a systematic assessment of the impact of various programmatic approaches, both preventive and ameliorative, in light of the growing scientific understanding of the topic.

By all indicators, the reproductive health of Americans has been deteriorating since 1980. Our nation is troubled by rates of teen pregnancies and newborn deaths that are worse than almost all others in the Western world. Science and Babies is a straightforward presentation of the major reproductive issues we face that suggests answers for the public. The book discusses how the clash of opinions on sex and family planning prevents us from making a national commitment to reproductive health; why people in the United States have fewer contraceptive choices than those in many other countries; what we need to do to improve social and medical services for teens and people living in poverty; how couples should "shop" for a fertility service and make consumer-wise decisions; and what we can expect in the futureâ€"featuring interesting accounts of potential scientific advances.

This examination of changes in adolescent fertility emphasizes the changing social context within which adolescent childbearing takes place.

Adolescence is a developmental period of accelerating physical, psychological, social! cultural, and cognitive development, often characterized by confronting and surmounting a myriad of challenges and establishing a sense of self-identity and autonomy. It is also, unfortunately, a period fraught with many threats to the health and well-being of adoles cents and with substantial consequent impairment and disability. Many of the adverse health consequences experienced by adolescents are, to a large extent, the result of their risk behaviors. Many adolescents today, and perhaps an increasing number in the future, are at risk for death, disease, and other adverse health outcomes that are not primarily biomedical in origin. In general, there has been a marked change in the causes of morbidity and mortality among adolescents. Previously, infectious diseases accounted for a dispro portionate share of adolescent morbidity and mortality. At present, however, the over whelming toll of adolescent morbidity and mortality is the result of lifestyle practices.
