The Association between Body Mass Index and Osteoporosis in Patients Referred for a Bone Mineral Density Examination

Abstract

Women with low BMI are at increased risk of osteoporosis. The change in risk associated with a 1 unit change in BMI ( approximately 5-8 lb) is of greater magnitude than most other modifiable risk factors. To help reduce the risk of osteoporosis, patients should be advised to maintain a normal weight.
