Risk of Knee Osteoarthritis With Obesity, Sarcopenic Obesity, and Sarcopenia.
Obesity, defined by anthropometric measures, is a well-known risk factor for knee osteoarthritis (OA), but there is a relative paucity of data regarding the association of body composition (fat and muscle mass) with risk of knee OA. We undertook this study to examine the longitudinal association of body composition categories based on fat and muscle mass with risk of incident knee OA. ⋯ In this large longitudinal cohort, we found body composition-based obesity and sarcopenic obesity, but not sarcopenia, to be associated with risk of knee OA. Weight loss strategies for knee OA should focus on obesity and sarcopenic obesity.
