Young Adult Medicine Overview

Principles

Definition

Young adult medicine is a specialized medical field dedicated to the comprehensive physical, emotional, and social health needs of individuals transitioning from adolescence through early adulthood (typically aged 10 to 25 years). This discipline provides developmentally appropriate care for this distinct age group, investigating the unique health challenges and complexities of this transitional period, and is significant for facilitating a healthy transition to adult healthcare systems and optimizing long-term well-being.

Longitudinal Developmental Surveillance era

J. M. Tanner [1] was active across Karolinska Institutet [3] and University College London [4] during this era. Tanner [1] articulated the Clinical longitudinal standards for height, weight, height velocity, weight velocity, and stages of puberty [7], establishing a framework that enabled longitudinal surveillance and cross-site comparability—key for informing prevention and early intervention in adolescent health. Denise B. Kandel [2] was associated with University of California, Santa Barbara [5] and Columbia University [6] during this era. Her 1975 paper Stages in adolescent involvement in drug use [8] outlined developmental stages of drug involvement, providing a lens for surveillance and prevention that guided teen-focused interventions in this era.

Trajectory Measurement and Prevention era

During 1986–2008, leading figures in young-age medicine integrated trajectory-based outcome measurement with developmental psychopathology and prevention science to inform clinical practice. Dante Cicchetti advanced the developmental psychopathology framework, articulating how early risk and resilience unfold along longitudinal trajectories and how measurement should capture functional impairment and adaptive development. Terrie E. Moffitt's developmental taxonomy of antisocial behavior—distinguishing life-course-persistent and adolescent-limited trajectories—provided a rigorous basis for tailoring prevention interventions and validating longitudinal risk models. Alan E. Kazdin advanced prevention science and outcome assessment, while James W. Varni contributed standardized quality-of-life metrics like the PedsQL to anchor surveillance and guide translational application to guidelines.

Structured Transition Integration era

Samuel S. Gidding [1] stands as a pivotal figure in young adult medicine during the Structured Transition Integration era, with affiliations at Harvard University [4] and the American College of Preventive Medicine [3]. A defining contribution in this era is the Clinical Practice Guideline for Screening and Management of High Blood Pressure in Children and Adolescents [6], which established standardized pediatric hypertension criteria and created a framework for risk surveillance across age boundaries to support structured transitions. Flynn [2] has been affiliated with Harvard University [4] and the University of California, San Francisco [5] during this era. Flynn [2] contributed to the 2017 Clinical Practice Guideline for Screening and Management of High Blood Pressure in Children and Adolescents [6], illustrating how cross-institutional collaboration advanced unified risk surveillance and transfer planning across pediatric and young adult care.
