Christiansen MB, Thoma LM, Master H, et al. - The present study was conducted to explore an 8-year variation in waist circumference (WC) with the risk of incident low physical function over 1 year in adults with, or at risk of, knee osteoarthritis. Researchers applied data from the Osteoarthritis Initiative. They assessed variation in WC from study enrollment (0 month) to the 96-month visit and classified as Increase (≥ 5cm gain) or Maintain (< 5cm gain). The risk of incident low physical function was increased by increasing WC in the following year. The results considered that maintaining WC may mitigate developing low physical function.
