    摘 要:目的 分析门诊未有明确诊断的顽固性下腰痛患者骨密度(bone mineral density，BMD)及骨质疏松(osteoporo-sis，OP)患病率变化规律，为骨质疏松预防提供科学依据. 方法 分别对患有未能明确诊断的顽固性下腰痛的体力劳动者与非体力劳动者进行整群随机抽样，抽取样本共429人，准确记录性别和年龄，采用DEXA(双能X线骨密度仪)测受试者L2-4 BMD，进行比较和统计分析. 结果 随增龄下腰痛患者骨密度逐渐下降，同龄男性BMD大于女性BMD，非体力劳动者大于体力劳动者.骨质疏松患病率随增龄而上升，体力劳动者患病率大于非体力劳动者，尤其是50岁时变化最明显. 结论 50岁以后女性下腰痛患者，特别是体力劳动者，OP的发生率较高.
