Juvenile Idiopathic Arthritis (JIA) is the most common rheumatic disease of childhood. It may cause joint pain and disability if not treated. Social factors, such as the circumstances in which people live and grow, may affect a child’s course with JIA. However, the relationships between these factors and JIA are not understood. To make sure that all children, no matter their circumstance, have the best outcome, we need to better understand this problem. We will study the relationships between social factors on arthritis outcomes. We will also study if there are factors in a person’s community that may help them do well despite challenges. We will speak with families and patients directly about these experiences. Our findings will help create interventions to improve the unfair differences between patients based on social differences. This will help reach our goal of fair care for all.
