Overweight: advancing our understanding of its impact on the knee and the hip.

摘要

In their study, Reijman et aV (see page 158) report findings that show an association between an increased body mass index (BMI) and greater risk of both incident knee osteoarthritis and knee osteoarthritis progression, but no association between an increased BMI and risk of either incident or progressive hip osteoarthritis. These results confirm what previous studies-that is, studies that were not specifically designed to look at the effect of BMI on the knee and the hip-had hinted at, that BMI has no effect or a smaller effect at the hip than at the knee. As the first study in which BMI effects on the knee and hip were examined in the same population, the study by Reijman et al is a landmark study.
