What is the typical age range for adolescents as defined in health studies?

The age range of 12-18 years is widely accepted in health studies as encompassing adolescence, a period characterized by significant physical, emotional, and social development. This stage generally begins with the onset of puberty around age 12 and continues into late adolescence at about age 18. During this time, individuals undergo various changes and face unique challenges, making it vital for health studies to define this age group accurately to address their specific health needs and developmental milestones. This range helps health professionals understand and cater to the specific issues adolescents may encounter, such as mental health considerations, risk-taking behaviors, and the impact of social environments on health outcomes. Such a definition allows for targeted interventions and research that can effectively support this population.
