Multivariable logistic regression identified correlates of physical therapy utilization, with models adjusted for body mass index and age.

Factors independently associated with increased odds of physical therapy utilization were female sex (odds ratio [OR] = 3.06, 95% CI = 1.58\u20135.93), bachelor degree or higher degree (OR = 2.44, 95% CI = 1.15\u20135.16), prior knee injury (OR = 1.86, 95% CI = 1.08\u20133.19), and duration of knee OA symptoms (OR = 2.16, 95% CI = 1.09\u20134.29 for &amp;gt;5\u201310 years; OR = 2.11, 95% CI = 1.10\u20134.04 for &amp;gt;10 years).

Women and those with a bachelor degree or higher degree, prior knee injury, and longer duration of knee OA symptoms were more likely to have used therapy previously. Differences by race in the link between joint injection and physical therapy utilization may reflect a reduced likelihood of referral and decreased use of health interventions for symptomatic knee OA among non-whites, or both.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ptj\/pzy052","type":"journal-article","created":{"date-parts":[[2018,4,25]],"date-time":"2018-04-25T06:44:09Z","timestamp":1524638649000},"page":"670-678","source":"Crossref","is-referenced-by-count":28,"title":["Sociodemographic and Clinical Correlates of Physical Therapy Utilization in Adults With Symptomatic Knee Osteoarthritis"],"prefix":"10.1093","volume":"98","author":[{"given":"Maura D","family":"Iversen","sequence":"first","affiliation":[{"name":"Department of Medicine, Section of Clinical Sciences, Brigham & Women's Hospital, Harvard Medical School, Boston, Massachusetts; Department of Women's and Children's Health, Karolinska Institutet, Stockholm, Sweden; Thurston Arthritis Research Center, Univer-sity of North Carolina, Chapel Hill, North Carolina; and Department of Physical Therapy, Movement & Rehabilitation Sciences, Northeastern University, 360 Huntington Avenue, 301C Robinson Hall, Boston, MA 02115 (USA)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Todd A","family":"Schwartz","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, Gillings School of Global Public Health, University of North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johan","family":"von Heideken","sequence":"additional","affiliation":[{"name":"Department of Women's and Children's Health, Karolinska Institutet"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leigh F","family":"Callahan","sequence":"additional","affiliation":[{"name":"Thurston Arthritis Research Center and Department of Medicine, University of North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yvonne M","family":"Golightly","sequence":"additional","affiliation":[{"name":"Thurston Arthritis Research Center, Department of Medicine, and Department of Epidemiology, University of North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Goode","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Division of Physical Therapy, Duke University Medical Center, Durham, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Hill","sequence":"additional","affiliation":[{"name":"Department of Allied Health Sciences, Division of Physical Therapy, University of North Carolina.
