Adolescent health

Many recent shifts are propelling adolescence into the forefront of global public health. There is a youth bulge with 1.8 billion, 10–24-year-olds comprising over a quarter of the global population. Nearly 90% live in low- and middle-income countries (LMIC). Dramatic declines in mortality and disease burden in infancy and early childhood in many countries have resulted in a focus on growing adolescent health problems including mental disorders, the consequences of unsafe sexuality, the growing rates of non-communicable disease risks, and the impact of injuries and violence on this age group. Youth-friendly health services have the potential to promote equity, effectiveness, accessibility, acceptability, and appropriateness of care, including early interventions for major health risks. Prevention frameworks have integrated life-course epidemiology with strategies developed in the social and behavioural sciences. There is some evidence that involving young people in the conceptualization and implementation of some of these interventions improves the outcomes.
