In search of risk factors for chronic pain in adolescents: a case-control study of childhood and parental associations.

Objectives: This study was designed to investigate whether an individual and parental history of functional pain syndromes (FPS) is found more often in adolescents suffering from chronic pain than in their pain-free peers.

Methods: Our case-control study involved 101 adolescents aged 10-18 years. Cases were 45 patients of the Chronic Pain Clinic at Sydney Children's Hospital with diverse chronic pain disorders.
