目的 调查北京首都钢铁公司（以下简称首钢）腰背痛、脊柱关节炎（SpA）、强直性脊柱炎（AS）的患病率及就诊情况.方法 根据Rudwaleit等制定的腰背痛和SpA问卷调查表,以分工厂为单位对所有在职及退休职工以非抽样普查方式进行调查.共对12 125人进行4级调查,对筛出的疑似者进行骶髂关节X线及HLA-B27检查.SpA的分类标准采用2009年国际强直性脊柱炎协会（ASAS）制定的标准.结果 腰背痛是常见症状,首钢职工的腰背痛发生率为42.7%,其中SpA患病率为0.58%,AS患病率为0.36%.由于认识不够,AS患者中已诊断并接受治疗者仅占28.9%.结论 首钢职工AS患病率与我国其他地区流行病学调查结果相近普通人群对SpA和AS的认知尚需进一步普及.
