Natural history of pain and disability among African-Americans and Whites with or at risk for knee osteoarthritis: A longitudinal study.

ABSTRACT:

Objective

Compare knee pain and disability between African Americans (AAs) and Whites (WHs), with or at risk of knee osteoarthritis (KOA), over 9 years, and evaluate racial disparities in KOA-related symptoms across socioeconomic and clinical characteristics.

Design

Osteoarthritis Initiative (OAI) participants were evaluated annually over 9 years for pain and disability, assessed by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and a numerical rating scale (NRS) for knee pain severity. Mean annual WOMAC pain, NRS pain, and WOMAC disability levels were estimated by race using mixed effects models, adjusted for age, sex, education, marital status, body mass index (BMI), depression, and baseline Kellgren-Lawrence grade score. Race-specific mean WOMA
