膝关节骨关节炎（OA）对少数种族和民族的影响尤为严重。非西班牙裔黑人（NHB）报告的膝关节OA症状的患病率和严重程度高于非西班牙裔白人（NHW）。贫困在解释这种差异方面所起的作用尚不清楚。目的本横断面研究的总体目的是确定种族/种族在膝关节疼痛和身体功能方面的差异是否因贫困状况而异。设计患有或有膝关节炎风险的nhb和NHW成年人自我报告社会人口统计信息，并完成西安大略和麦克马斯特大学骨关节炎指数（WOMAC）和短物理性能电池（SPPB）。根据住户人数调整了年收入，以确定贫困状况（即生活在贫困线以上或以下）。结果120人生活在贫困线以上（49% NHB, 77% NHW）， 71人生活在贫困线以下（51% NHB, 23% NHW）。调整后的多变量模型显示，贫困状况对膝痛（p= 0.036）和WOMAC的身体功能（p= 0.032）以及SPPB的身体功能（p= 0.042）有显著的民族/种族相互作用。事后对比普遍显示，生活在贫困线以上的NHW成年人膝盖疼痛最轻，身体功能最好，而生活在贫困线以下的NHB成年人膝盖疼痛最严重，身体功能最差。本研究的结果通过强调在研究疼痛和身体功能的种族/种族差异时考虑贫困和/或其他社会经济地位指标的重要性，为文献提供了补充。
BackgroundKnee osteoarthritis (OA) disproportionately affects racial and ethnic minorities. Non-Hispanic Blacks (NHB) report a higher prevalence and severity of knee OA symptoms than their non-Hispanic White (NHW) counterparts. The role of poverty in explaining this disparity remains unclear.ObjectiveThe overall aim of this cross-sectional study was to determine whether ethnic/racial differences in knee pain and physical function varied according to poverty status.DesignNHB and NHW adults with or at risk of knee OA self-reported sociodemographic information, and completed the Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) and the Short Physical Performance Battery (SPPB). Annual income was adjusted for number of household occupants to determine poverty status (i.e., living above versus below poverty line).ResultsFindings revealed 120 individuals living above the poverty line (49% NHB, 77% NHW) and 71 individuals living below the poverty line (51% NHB, 23% NHW). Adjusted multivariable models revealed significant ethnic/race by poverty status interactions for knee pain (p= 0.036) and physical function (p= 0.032) on the WOMAC, as well as physical function on the SPPB (p= 0.042). Post hoc contrasts generally revealed that NHW adults living above the poverty line experienced the least severe knee pain and best physical function, while NHB adults living below the poverty line experienced the most severe knee pain and poorest physical function.ConclusionsResults of the present study add to the literature by emphasizing the importance of considering poverty and/or other indicators of socioeconomic status in studies examining ethnic/racial disparities in pain and physical function.
