In a population based epidemiological survey of juvenile chronic arthritis (JCA), performed in Western Sweden in 1983, an incidence of 12/100,000 was found. The estimated prevalence was 56/100,000. Subgroup distribution showed a preponderance of mono- and pauciarticular forms. The peak age of onset was between 0 and 4 years of age. Girls predominated over boys in a ratio of 3:2. Overall, 30% were antinuclear antibody (ANA) positive, 9% rheumatoid factor (RF) positive, and eye involvement occurred in 10% of the children. The results suggest differences in population based studies of JCA compared with previously reported hospital based series.
1983年在瑞典西部进行的一项基于人群的青少年慢性关节炎(JCA)流行病学调查发现,其发病率为12/10万。估计患病率为56/10万。亚组分布显示单关节和少关节形式占优势。发病高峰年龄在0至4岁之间。女孩与男孩的比例为3:2。总体而言,30%的患儿抗核抗体(ANA)呈阳性,9%类风湿因子(RF)呈阳性,10%的儿童有眼部受累。结果表明,与之前报道的基于医院的系列研究相比,基于人群的JCA研究存在差异。
