Abstract

Seventeen to 20 percent of children with recent onset arthritis have juvenile idiopathic arthritis (JIA). The annual incidence of JIA in Norway ranges from 14-23/100000 children according to population based prospective studies. In other Scandinavian countries an incidence of 11 to 19/100000 has been found in epidemiological studies. A point prevalence of JIA of 86-148/100000 has been found. The varying results may have been influenced by differences in the classification or exclusion criteria used, varying referral bias and limited population samples studied. They may also represent time trends or geographic variations. Female gender, knee or small joint involvement, a positive antinuclear antibody, high platelet counts and genetic factors have been associated with the development of JIA in children with undifferentiated early
arthritis. Further studies of large populations over time are necessary to reveal true geographic variations in the frequency of JIA, based on genetic or environmental factors.
