Objective To explore the relationship between bone mineral density(BMD) and body tat disrribution in the aged in Ningbo area of China. Methods The BMD of lumbar vertebra and total body bones as well as body composition were measured by dual-energy X-ray absorptiometry (DXA) in 61 aged males, and also in 63 aged females as control group. Results In the aged males, a negative correlation was found between BMD and age, while BMI, muscle, trunk fat were positively correlated with BMD. As for the aged female, age, BMI, muscle and fat were all positively correlated with BMD. Conclusions The correlation between body fat and BMD is closer in females than in males in the aged. There is a positive correlation between trunk fat and lumbar spine BMD, and it indicates that central obesity may have a protective effect on lumbar spine BMD.
