We examined the associations of sociodemographic variables, health behaviors, health status and psychological well being with radiographic knee osteoarthritis (OA) and self-reported knee pain for 4056 US adults aged 45-74 years. Among persons with or without knee OA known correlates of radiographic knee OA (age, sex, race, obesity) were generally not associated with knee pain. Radiographic severity, psychological well being and health status were associated with knee pain, both among persons with and without radiographic knee OA, suggesting that nonradiographic correlates of self-reported knee pain are independent of whether a person has radiographic knee OA.
我们研究了4056名年龄在45 - 74岁的美国成年人的社会人口统计学变量、健康行为、健康状况和心理健康与膝关节影像学骨关节炎（OA）以及自我报告的膝关节疼痛之间的关联。在患有或未患膝关节OA的人群中，膝关节影像学OA的已知相关因素（年龄、性别、种族、肥胖）通常与膝关节疼痛无关。影像学严重程度、心理健康和健康状况与膝关节疼痛相关，无论是否患有膝关节影像学OA，这表明自我报告的膝关节疼痛的非影像学相关因素独立于一个人是否患有膝关节影像学OA。
