Abstract

OBJECTIVE

To identify the risk of hip fracture in patients with rheumatoid arthritis and those taking corticosteroids.

METHODS

In a population based case-control study, we compared 300 consecutive patients with hip fracture aged 50 years and over from a defined district and 600 age and sex matched community controls.

RESULTS

The risk of hip fracture was increased in patients with rheumatoid arthritis (odds ratio (OR) 2.1; 95% confidence interval (CI) 1.0 to 4.7) and those receiving corticosteroids (OR 2.7; 95% CI 1.2 to 5.8). The risk attributable to rheumatoid arthritis was markedly reduced by adjusting for functional impairment, while that for steroid use remained after adjusting for body mass index, smoking, alcohol, and functional status.

CONCLUSIONS

Hip fracture risk is approximately doubled amongst patients with rheumatoid arthritis and among those taking steroids. These risk increases are, to some extent, independent of each other. In rheumatoid arthritis, the risk was most closely associated with functional impairment, whereas steroid use did not appear to be confounded by this variable.

摘要

目的

确定类风湿关节炎患者及服用皮质类固醇药物患者发生髋部骨折的风险。

方法

在一项基于人群的病例对照研究中,我们比较了来自特定地区的300例年龄在50岁及以上的连续髋部骨折患者和600例年龄及性别匹配的社区对照者。

结果

类风湿关节炎患者(比值比(OR)2.1;95%置信区间(CI)1.0至4.7)及接受皮质类固醇药物治疗的患者(OR 2.7;95% CI 1.2至5.8)发生髋部骨折的风险增加。通过调整功能障碍因素,类风湿关节炎所致的风险显著降低,而在调整体重指数、吸烟、饮酒及功能状态后,使用类固醇药物所致的风险依然存在。

结论

类风湿关节炎患者及服用类固醇药物的患者发生髋部骨折的风险大约增加一倍。这些风险增加在一定程度上相互独立。在类风湿关节炎中,风险与功能障碍最为密切相关,而使用类固醇药物似乎不受该变量的影响。
