We followed 386 children who met the criteria for juvenile rheumatoid arthritis (JRA) an average of 89 months. Hip involvement in JRA results in poor functional capacity. The prognosis for the pauciarticular group is good, but patients with onset at age greater than 6 years appear to do worse than those aged less than 6 years. In the polyarticular group, age of onset did not change the prognosis, whereas the systemic-onset group aged less than 6 years had a worse prognosis and more frequent radiographic changes than the older group.
我们对386名符合青少年类风湿性关节炎（JRA）标准的儿童进行了平均89个月的随访。JRA累及髋关节会导致功能能力较差。少关节型组的预后良好，但发病年龄大于6岁的患者似乎比年龄小于6岁的患者预后更差。在多关节型组中，发病年龄并未改变预后，而年龄小于6岁的全身型组比年龄较大的组预后更差，影像学改变也更频繁。
