Foot Osteoarthritis Frequency and Associated Factors in a Community‐Based Cross‐Sectional Study of White and African American Adults

Objective Few studies have explored foot osteoarthritis (OA) in the general population. The purpose of this study was to determine the frequency of foot OA and identify associated factors in a cross‐sectional analysis of a large community‐based cohort. Methods Data were from the 2013–2015 study visi...

Description
Summary:Objective Few studies have explored foot osteoarthritis (OA) in the general population. The purpose of this study was to determine the frequency of foot OA and identify associated factors in a cross‐sectional analysis of a large community‐based cohort. Methods Data were from the 2013–2015 study visit of the Johnston County OA Project. Radiographic OA of the foot was defined using the La Trobe radiographic atlas (≥2 osteophytes or joint space narrowing in at least 1 of 5 joints). Symptomatic OA of the foot was defined as foot radiographic OA with pain, aching, or stiffness in the same foot. At the foot‐level, separate logistic regression models with generalized estimating equations to account for intraperson correlations were performed to examine associations of foot radiographic OA or symptomatic OA with age, body mass index (BMI), sex, race, educational attainment, and previous foot injury. Results Of 864 participants with available data (mean age 71 years, mean BMI 30 kg/m2, 68% women, 33% African American, 13% 2 times the odds of radiographic OA and >5 times the odds of symptomatic OA in adjusted models. Conclusion Foot radiographic OA and foot symptoms were common in the sample, but both conditions simultaneously (i.e., symptomatic OA) occurred infrequently. Notably, obesity was linked with foot symptomatic OA, perhaps implicating metabolic or mechanical influences.
