Does More Dairy Improve Knee OA Risk?

— Dutch study finds inverse association for some dairy products

MedicalToday

A recent from the Netherlands explored the potential association between dairy consumption and knee osteoarthritis (OA), and found that higher intake of full-fat dairy and Dutch cheese -- but not milk -- was significantly associated with the lower risk of knee OA.

The authors studied the risk of knee OA in 3,010 individuals, ages 40-75 years, comparing those without knee OA to the 427 (14%) participants classified as having knee OA. Knee OA classification was based on a modified version of the American College of Rheumatology clinical classification criteria (minus knee crepitus measure). Data on dairy consumption were evaluated using a 253-item survey covering 47 dairy products.

By comparing the highest and lowest tertiles of dairy intake, the researchers found significant inverse association between knee OA and intake of full-fat dairy:

  • Full-fat dairy: OR 0.68 (95% CI 0.50-0.92)
  • Dutch cheese (semi-hard cheeses such as Gouda, Edam, or Maasdam): OR 0.75 (95% CI 0.56-0.99)
  • Other dairy product categories, including milk: No significant associations

Further research is needed to assess the relationship between dairy consumption, and in particular semi-hard cheeses, with incident knee OA.
