N2  - INTRODUCTION: To examine data from the Johnston County Osteoarthritis (OA) Project for independent associations of educational attainment, occupation and community poverty with tibiofemoral knee OA. METHODS: A cross-sectional analysis was conducted on 3591 individuals (66% Caucasian and 34% African American). Educational attainment (<12 years or [greater than or equal to] 12 years), occupation (non-managerial or not), and Census block group household poverty rate (<12%, 12 to 25%, >25%) were examined separately and together in logistic models adjusting for covariates of age, gender, race, body mass index (BMI), smoking, knee injury and occupational activity score. Outcomes were presence of radiographic knee OA (rOA), symptomatic knee OA (sxOA), bilateral rOA and bilateral sxOA. RESULTS: When all three socioeconomic status (SES) variables were analyzed simultaneously, low educational attainment was significantly associated with rOA (OR=1.44 95% CI [1.20, 1.73]), bilateral rOA (OR=1.43 [1.13, 1.81]), and sxOA (OR=1.66 [1.34, 2.06]), after adjusting for covariates. Independently, living in a community of high household poverty rate was associated with rOA (OR=1.83 [1.43, 2.36]), bilateral rOA (OR=1.56 [1.12, 2.16]), and sxOA (OR=1.36 [1.00, 1.83]). Occupation had no significant, independent associations beyond educational attainment and community poverty. CONCLUSIONS: Both educational attainment and community SES were independently associated with knee OA after adjusting for primary risk factors for knee OA.<p />  <p>Language: en</p>
