Abstract: Engaging in regular exercise is essential for managing knee osteoarthritis (KOA) symptoms. Despite the established findings, sustained exercise adoption remains a challenge for KOA patients, with notable disparities among Hispanic patients, warranting a need to identify determinants that explain the racial discrepancy in exercise participation. The purpose of this study was to employ a biopsychosocial model to identify determinants of exercise participation and highlight racial disparities. Patients (n = 163) from a university hospital clinic were medically examined to be considered eligible for the study based on radiographs. Eligible participants completed validated survey measures that assessed exercise participation over the past two weeks, along with measures from biological, psychological and social domains to predict future intention exercise. Structural equation modelling tested hypothesized the paths. Past exercise behavior predicted attitudes, self-efficacy, and future exercise intentions. Pain catastrophizing correlated with exercise participation, but the competing effects of physician and (personal) social support on exercise nullified the significance of pain catastrophizing to exercise participation. Significant ethnicity comparisons found non-Hispanic white patients to have higher education, income, lower BMI, stronger scores on attitudes and self-efficacy, and greater exercise participation time. Non-significant effects between the two ethnicities include intention, physician support, and social support. Designing an intervention that helps foster support from the patient's physician and proximal friends/family members can play a vital role in exercise participation for both ethnicities. Additional focus on developing attitudes and self-efficacy among Hispanics can address some disparities. Further notes on promoting exercise equity using a biopsychosocial approach are provided.
