The study was conducted using a cross sectional design to determine the prevalence of Juvenile chronic arthritis (JCA) among 10 to 15 years old school children in Alexandria, and to develop (if possible) a tool for screening children for arthritis. The study included 1500 children selected by using a multistage stratified random sample of students enrolled in the primary and preparatory schools in Alexandria Governorate. The results of this study indicated that the prevalence of JCA was 3.3 per 1000. Also a simple tool, composed of some questions, could effectively identify children with JCA. However, clinical examination supported by a history from the child provides the best reliable means of diagnosis. The present study recommended the use of community rather than hospital based surveys for estimating the true prevalence of the disease.
该研究采用横断面设计，以确定亚历山大港10至15岁学童中青少年慢性关节炎（JCA）的患病率，并（如有可能）开发一种用于筛查儿童关节炎的工具。该研究纳入了1500名儿童，这些儿童是通过对亚历山大省中小学注册学生进行多阶段分层随机抽样选取的。这项研究的结果表明，JCA的患病率为每1000人中有3.3人。此外，一个由一些问题组成的简单工具可以有效识别患有JCA的儿童。然而，结合儿童病史的临床检查是最可靠的诊断方法。本研究建议采用基于社区而非医院的调查来估计该疾病的真实患病率。
