OBJECTIVE: To examine the associations of sex, body mass index (BMI), and age
with knee osteoarthritis (OA) symptomatic severity. DESIGN: A cross-sectional
retrospective analysis. SETTING: Patients completed the Western Ontario and
McMaster Universities Osteoarthritis Index (WOMAC) questionnaire and Medical
Outcomes Study 36-Item Short-Form Health Survey (SF-36). Data were acquired from
a stored database of a private therapy center. PARTICIPANTS: Patients (N=1487)
with symptomatic knee OA were evaluated. INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURES: WOMAC questionnaire and SF-36. RESULTS: BMI correlated
significantly with worse knee OA symptoms for all WOMAC and SF-36 subcategories
(all P </=.001). Age correlated significantly with worse symptoms only for WOMAC
function and SF-36 physical functioning (P=.001 and P=.009, respectively). A
significant difference across BMI quintiles was found for all WOMAC and SF-36
subcategories (all P </=.01). Women showed worse knee OA symptoms in all WOMAC
and SF-36 subcategories (all P </=.001). There was a significant interaction of
sex by BMI in WOMAC pain and WOMAC function (P=.01 and P=.02, respectively).
CONCLUSIONS: Based on the results of this analysis, it can be concluded that
women and patients with a higher BMI with knee OA are at a greater risk for worse
symptoms.
