Adolescenceâ€"beginning with the onset of puberty and ending in the mid-20sâ€"is a critical period of development during which key areas of the brain mature and develop. These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€"rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish.

Research on physical maturity has demonstrated conclusively that the assumption of an age-homogenous development does not always hold true. This volume presents a biosocial model focusing on the role of individual differences in biological maturation to be used as a framework for empirical studies exploring adolescent female development. The longitudinal design of the research program offers the possibilities to examine both short- and long-term consequences for individual variations in pubertal development. In the present volume, the data for these analyses consist of a broad range of biological, mental, psychological, behavioral, and social factors extending from the age of 10 to the age of 30. Some of the questions the present volume attempts to answer are: * Are variations in the timing of pubertal development among girls related to their psychological and social life situation in the adolescent years? If so, when is the relation most prominent? In what areas is the relation most prominent? How does the relation come about? * Do interindividual differences in physical maturation have any long-term consequences for adult life? If so, in what areas, for which girls, and through which developmental processes does pubertal development operate? The long-term consequences are a major concern addressed in considerable detail.

More children born today will survive to adulthood than at any time in history. It is now time to emphasize health and development in middle childhood and adolescence--developmental phases that are critical to health in adulthood and the next generation. Child and Adolescent Health and Development explores the benefits that accrue from sustained and targeted interventions across the first two decades of life. The volume outlines the investment case for effective, costed, and scalable interventions for low-resource settings, emphasizing the cross-sectoral role of education. This evidence base can guide policy makers in prioritizing actions to promote survival, health, cognition, and physical growth throughout childhood and adolescence.

Discusses the biocultural and evolutionary factors that direct growth, and intrinsic and extrinsic factors affecting individual development.

This updated edition features three new chapters and current research findings. Topics include prenatal growth and functional development, motor development, thermoregulation, obesity in childhood and adolescence and more.
