Self-Reported Osteoarthritis, Ethnicity, Body Mass Index, and Other Associated Risk Factors in Postmenopausal Women-Results from the Women's Health Initiative

The objective of this analysis was to assess risk factors for self‐reported osteoarthritis (OA) in an ethnically diverse cohort of women. The participants were postmenopausal women aged 50 to 79 (n=146,494) participating in the clinical trial and observational study of the Women's Health Initia...

Description
Summary:The objective of this analysis was to assess risk factors for self‐reported osteoarthritis (OA) in an ethnically diverse cohort of women. The participants were postmenopausal women aged 50 to 79 (n=146,494) participating in the clinical trial and observational study of the Women's Health Initiative (WHI). Baseline OA and risk factors were collected from WHI questionnaires. Logistic regression was used to find the association between the risk factors and OA. Risk factor distribution and ethnicity interaction terms were used to assess ethnic differences in OA risk. Forty‐four percent of the participants reported OA. Older age (odds ratio (OR)70–79 vs 50–59=2.69, 95% confidence interval (CI)=2.60–2.78) and higher body mass index (BMI) (ORBMI≥40.0 vs
