However, few studies have evaluated its importance in ethnicity, particularly the Hispanic population. This study compares pain intensity (VAS), function (WOMAC), and pain catastrophizing (PCS) between Hispanic <jats:bold>(HP)<\/jats:bold> and non-Hispanic White patients <jats:bold>(NHWP)<\/jats:bold> stratified by socio-economic status (SES) and osteoarthritis radiographic K-L grade.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>A cross-sectional study of patients from a tertiary care clinic between July 2021 and December 2022 was performed. Patients with knee pain, radiographs, and doctor-diagnosis of KOA completed questionnaires in English or Spanish. Descriptive statistics characterized demographic differences between <jats:bold>NHWP<\/jats:bold> and <jats:bold>HP<\/jats:bold> in VAS, WOMAC, and PCS. Two one-way analyses of variance evaluated the effect of both ethnicity and sex, with subgroup analyses stratifying by K-L grade. Multivariate general linear models assessed primary outcomes while controlling for confounders.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>A total of 195 subjects (<jats:bold>HP<\/jats:bold>\u2009=\u2009145, <jats:bold>NHWP<\/jats:bold>\u2009=\u200950) were included. <jats:bold>HP<\/jats:bold> exhibited higher VAS, PCS, and WOMAC scores compared to <jats:bold>NHWP<\/jats:bold>. PCS was higher in <jats:bold>HP<\/jats:bold> (p\u2009=\u20090.004, mean\u2009=\u20098.89) than <jats:bold>NHWP<\/jats:bold> (mean\u2009=\u20094.58), as was <jats:bold>VAS<\/jats:bold> (p\u2009&lt;\u20090.001, mean\u2009=\u20094.28 vs. 2.74) and WOMAC (p\u2009=\u20090.029, mean\u2009=\u200927.86 vs. 21.58). These differences remained when controlled for NSES and K-L grade. Stratifying by sex and comparing primary outcomes between <jats:bold>HP<\/jats:bold> and <jats:bold>NHWP<\/jats:bold>, male <jats:bold>HP<\/jats:bold> had greater VAS (p\u2009=\u2009.021, mean\u2009=\u20093.83 vs. 2.42) and PCS (p\u2009=\u2009.008, mean\u2009=\u20098.83 vs. 3.35), while female <jats:bold>HP<\/jats:bold> had greater <jats:bold>VAS<\/jats:bold> (p\u2009=\u2009.019, mean\u2009=\u20094.62 vs. 3.08) and nonsignificantly greater PCS (p\u2009=\u2009.164, mean\u2009=\u20098.94 vs. 5.92).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p><jats:bold>HP<\/jats:bold> with KOA reported greater pain severity, functional limitation, and PCS.<\/jats:p>\n<jats:p>compared with <jats:bold>NHWP<\/jats:bold>, even after adjusting for NSES and K-L grade.
