定义
幼年特发性关节炎（JIA）是用来描述一组原因不明的炎症性关节病的术语，这些疾病在16岁以前开始，持续6周以上。已经定义了六种疾病：系统性发病的青少年特发性关节炎（以前称为Still病）、少关节炎、类风湿因子阳性多关节炎、类风湿因子阴性多关节炎、附着点炎相关性关节炎（脊柱关节病）和青少年型银屑病性关节炎（见这些术语）。第七类包括未分类的关节炎类型（不符合任何已定义的疾病或符合一个以上疾病定义的类型）。
Juvenile idiopathic arthritis (JIA) is the term used to describe a group of inflammatory articular disorders of unknown cause that begin before the age of 16 and last over 6 weeks. Six disorders have been defined: systemic-onset juvenile idiopathic arthritis (formerly referred to as Still's disease), oligoarticular arthritis, rheumatoid factor-positive polyarthritis, rheumatoid factor-negative polyarthritis, enthesitis-related arthritis (spondyloarthropathies), and the juvenile form of psoriatic arthritis (see these terms). A seventh category has been defined comprising unclassified types of arthritis (types that do not correspond to any of the defined disease or that correspond to more than one of the disease definitions).
