Which patient group is primarily affected by juvenile idiopathic arthritis?

Juvenile idiopathic arthritis (JIA) is a form of arthritis that specifically affects children, typically those who are 16 years of age or younger. It is characterized by inflammation of the joints and can lead to pain, swelling, and potential long-term joint damage if not treated properly. The term "juvenile" explicitly indicates that this condition is diagnosed in young individuals, particularly in early childhood.

The condition can have various subtypes, but its prevalence among young children highlights its classification as one of the most common forms of arthritis in this age group. Understanding that JIA is primarily seen in children underscores the importance of early diagnosis and intervention to manage symptoms and minimize complications that may arise as these children grow.
