Exercise Use in a Diverse Ethnic Population with OA

Arthritis Care Res; ePub 2019 Feb 14; Vina, et al

Among patients with knee/hip osteoarthritis (OA), Hispanics were less likely to exercise for OA treatment, according to a recent study. Therefore, increased knowledge about the benefits of exercise for treatment and improved familiarity with exercise as treatment for OA may increase exercise use.After identifying knee/hip OA study participants, researchers administered surveys to collect socio‐demographics, clinical information, and beliefs and attitudes about providers and treatments. They found:

  • Hispanics (n=130), compared to non‐Hispanics (n=232), were less likely to have private medical insurance (9.2% vs 31.0%) or to report having excellent/very good health (40.7% vs 52.6%).
  • They were also less likely to report using exercise for OA treatment the last 6 months (56% vs 73%).
  • When adjusted for age and disease severity, the ethnic difference in exercise use remained significant (OR 0.59).
  • In a multivariable logistic regression model, the following were associated with exercise use in the last 6 months: having knee instead of hip OA (OR 2.83), having family/friends who exercise (OR 3.20), having a good understanding of what happens after exercise (OR 2.19), and higher perceived benefit of exercise (OR 2.24).
