Quality-Adjusted Life-Years Lost Due to Physical Inactivity in a US Population With Osteoarthritis.

ABSTRACT:

Objective

One-half of the 14 million persons in the US with knee osteoarthritis (OA) are not physically active, despite evidence that physical activity (PA) is associated with improved health. We undertook this study to estimate both the quality-adjusted life-year (QALY) losses in a US population with knee OA due to physical inactivity and the health benefits associated with higher PA levels.

Methods

We used data from the Osteoarthritis Initiative and the Centers for Disease Control and Prevention to estimate the proportions of a US population with knee OA ages ≥45 years that are inactive, insufficiently active, and active, and the likelihood of a shift in their PA level. We used the OA Policy Model, a computer simulation of knee OA, to determine QALYs lost due to inactivity
