Evaluating the Relationships between Body Mass Index, Weight, and Bone Mineral Density in Men Using Dual-Energy X-Ray Absorptiometry

Body mass index (BMI) is used for the prediction and assessment of bone mineral density (BMD). BMD measurements are useful in the evaluation of the risk of osteoporotic fractures, diagnosis of osteoporosis, and efficient treatment.

In this study, 230 men (age: 50-70 years old) who referred to Isfahan Osteoporosis Center and had BMD scans of hip and lumbar spine were evaluated using a dual-energy X-ray absorptiometry (DXA) system.

Using Pearson's Correlation, we found significant direct relations between BMD of lumbar spine and weight (r = 0.301) and BMI (r = 0.314) and also between BMD of the hip and weight (r = 0.325) and BMI (r = 0.279).

BMI and weight had significant direct correlations with BMD of the hip and the spine.
