Abstract

Objective : Due to its high prevalence, osteoporosis is considered as a serious public health concern. Overweight is known to have a beneficial effect on bone mass density (BMD). But, there are not many studies about the independent effect of fat mass and lean mass on BMD. In this study, we investigated the association between the body composition and bone mass density.

Material and Methods : A total of 760 Korean (446 male, 314 female), who had undergone comprehensive routine health examinations at the Daegu Fatima Hospital, were included in this study. The bone mineral density of lumbar spines (L1 to L4) was measured by dual-energy X-ray absorptiometry. Bioelectrical impedance analysis was used to measure the body composition by composition analyzer (Inbody 3.0, Biospace, Seoul, Korea).

Results : The mean age of total subjects was 47.29 ± 11.60. There was significantly positive association between muscle mass and BMD of lumbar spines in both males and females. Fat mass was significantly related with BMD of lumbar spines in male subjects, but this association was not shown in females. After adjustments for age and height, the significant positive correlation between muscle mass and BMD of lumbar spines was retained in both males and females. In males, the positive association between fat mass and BMD of lumbar spines was only shown in L1 and L2. In females, all sites of lumbar spine were related with fat mass. 

Conclusion : In this study, muscle mass was highly related with BMD of lumbar spines in males and females. Association between fat mass and BMD was inconsistent. Muscle mass is more important that fat mass for BMD.
