We expect country\u2010specific differences in the physical activity levels between persons with knee OA compared to persons without knee OA. A varying degree of physical activity levels across countries would express a facilitating or impeding influence of the social, environmental, and other contextual factors on a physically active lifestyle.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Baseline cross\u2010sectional data from the European Project on Osteoarthritis were analyzed.

The magnitude of this difference varied across countries.

This national variation implies that low levels of physical activity among persons with knee OA cannot be explained exclusively by individual or disease\u2010specific factors, but that social, environmental, and other contextual factors should also be taken into
