Juvenile arthritis, including juvenile-onset spondyloarthritis (JSpA), is a group of chronic inflammatory conditions that affect children and adolescents under the age of 16. At the Canadian Spondyloarthritis Association, we understand the unique challenges faced by young people living with these conditions, as well as the concerns of their families and caregivers. This resource page is designed to provide clear, reliable information about juvenile arthritis—including symptoms, diagnosis, treatment options, and daily living support—to help young patients and their families navigate their journey with confidence and hope.
