Which age group is defined as "children" in the pediatric population?

The definition of "children" within the pediatric population generally encompasses the age range from 2 to 11 years. This classification is significant when considering various aspects of clinical research, such as dosage determination for medications, understanding developmental stages, and establishing informed consent processes in clinical trials involving pediatric subjects.

Children in this age group are often more than just toddlers, as they are capable of more complex interactions and decision-making regarding their participation in research. Moreover, this age range reflects a critical period for growth and development, where psychological and physical changes influence their responses to therapies and medical interventions.

The other age groups listed typically fall into different classifications within pediatrics. For instance, the range of 0 to 27 days pertains to newborns or infants, while 28 days to 23 months is usually categorized under infants and toddlers. The range from 12 to 16-18 years defines adolescents, a critical stage that includes different health considerations and developmental assessments distinct from those relevant to younger children. Understanding these distinctions is crucial for clinicians and researchers when designing and interpreting studies involving various pediatric populations.
