To determine the factors associated with self-reported pain and physical function in patients with hip osteoarthritis (OA).
Cross-sectional study.
Rehabilitation clinic in a Finnish hospital.
Participants with hip OA (N=118; 35 men, 83 women; age, 66.7+/-6.5y; range, 55-80y).
Not applicable.
Self-reported pain and self-reported disease-specific physical function were recorded by using the Western Ontario McMaster Universities Osteoarthritis Index. Self-reported generic physical function was analyzed by using the Finnish version of the RAND 36-Item Short-Form Health Survey. As listed in the International Classification of Functioning, Disability and Health model, the effects of personal factors (age, sex, education, depression, life satisfaction, smoking, years of sporting activities), pathophysiologic factors (radiologic score of hip OA, body mass index [BMI], comorbidities, duration of knee pain) and body functions and structures (measurement of leg extensor power, passive internal rotation and flexion of the hip joint, the six-minute walk test [6MWT], Timed Up & Go [TUG] test, ten-meter walk test, sock test) were analyzed.
The educational level (r=-.264, P<.001), comorbidities (r=.313, P<.001), and BMI (r=.252, P<.001) were identified as significant factors for self-reported disease-specific physical function as well as the educational level (r=.291, P<.001), life-satisfaction (r=-.319, P<.001), BMI (r=-.290, P<.001), and comorbidities (r=-.220, P<.005) for the self-reported generic physical function. No direct relationship with the pain and psychologic factors was detected. The number of comorbidities and duration of knee pain and life satisfaction explained 22% of self-reported pain. The number of comorbidities, passive hip flexion, and the TUG test explained 20% of self-reported disease-specific physical function whereas the passive hip flexion, 6MWT, and educational level explained 25% of self-reported generic physical function.
Educational level, life satisfaction, and number of comorbidities were identified as significant factors for both self-reported pain and physical functioning in hip OA. Performance measures are better predictors of physical function than pain in hip OA. Factors explaining disability and pain in hip OA are multidimensional and no single predicting factor was found to be superior to any other.
确定与髋骨关节炎（OA）患者自我报告的疼痛和身体功能相关的因素。
横断面研究。
芬兰一家医院的康复诊所。
髋OA患者（N = 118；35名男性，83名女性；年龄，66.7±6.5岁；范围，55 - 80岁）。
不适用。
使用西安大略和麦克马斯特大学骨关节炎指数记录自我报告的疼痛和疾病特异性身体功能。使用芬兰版的兰德36项简短健康调查分析自我报告的一般身体功能。按照国际功能、残疾和健康分类模型列出的内容，分析个人因素（年龄、性别、教育程度、抑郁、生活满意度、吸烟、体育活动年限）、病理生理因素（髋OA的放射学评分、体重指数[BMI]、合并症、膝关节疼痛持续时间）以及身体功能和结构（腿部伸肌力量测量、髋关节被动内旋和屈曲、六分钟步行试验[6MWT]、计时起立行走试验[TUG]、十米步行试验、穿袜试验）的影响。
教育程度（r = -0.264，P <.001）、合并症（r = 0.313，P <.001）和BMI（r = 0.252，P <.001）被确定为自我报告的疾病特异性身体功能的重要因素，教育程度（r = 0.291，P <.001）、生活满意度（r = -0.319，P <.001）、BMI（r = -0.290，P <.001）和合并症（r = -0.220，P <.005）为自我报告的一般身体功能的重要因素。未检测到与疼痛和心理因素的直接关系。合并症数量、膝关节疼痛持续时间和生活满意度解释了自我报告疼痛的22%。合并症数量、髋关节被动屈曲和TUG试验解释了自我报告的疾病特异性身体功能的20%，而髋关节被动屈曲、6MWT和教育程度解释了自我报告的一般身体功能的25%。
教育程度、生活满意度和合并症数量被确定为髋OA患者自我报告的疼痛和身体功能的重要因素。在髋OA中，功能表现指标比疼痛更能预测身体功能。解释髋OA残疾和疼痛的因素是多维度的，未发现单一预测因素优于其他因素。
