The epidemiology of hip fracture in Asia: an update.

Abstract

1. The incidence of hip fracture is increasing in urbanized parts of Asia. 2. The incidence of hip fracture in Asian populations is still only 60% of that in Caucasians. 3. The lower incidence of hip fracture in Asian populations is not due to a higher bone mineral density, but may be due to a shorter hip axis length. 4. A low dietary calcium intake, lack of physical activity and falls are important risk factors for hip fracture in Chinese.
