Adolescent health, or youth health, is the range of approaches to preventing, detecting or treating young people’s health and well-being. The term adolescent and young people are often used interchangeably, as are the terms Adolescent Health and Youth Health. Young people's health is often complex and requires a comprehensive, biopsychosocial approach.
Some young people engage in risky behaviours that affect their health and therefore the majority of health problems are psychosocial. Many young people experience multiple problems. These behaviours are established as a young person and go on to become the lifestyles of adults leading to chronic health problems. Social, cultural and environmental factors are all important. Young people have specific health problems and developmental needs that differ from those of children or adults: The causes of ill-health in adolescents are mostly psychosocial rather than biological. Young people often engage in health risk behaviours that reflect the processes of adolescent development: experimentation and exploration, including using drugs and alcohol, sexual behaviour, and other risk taking that affect their physical and mental health. Adolescent health also encompasses children's and young people's sexual and reproductive health (SRH).
