SUMMARY OBJECTIVE: This study aimed to explore the correlation between different body components and bone mineral density in healthy adults. METHODS: A total of 306 non-manual subjects, 161 males and 145 females, were selected from the physical examination center of our hospital from June to September 2019. They were divided into control group, overweight group, and obese group according to body mass index. The muscle mass and fat mass, body fat content, trunk fat mass, upper limb and thigh fat mass, bone density of femoral neck and lumbar vertebra, and bone mineral salt content of the whole body were measured by dual-energy X-ray absorptiometry. RESULTS: Body mass index, systolic blood pressure, diastolic blood pressure, femoral neck bone mineral density, bone mineral salt content, fat mass, muscle mass, upper limb fat mass, thigh fat mass, and trunk fat mass in the overweight group and obese group were all higher than those in the control group (P<0.05). The fat mass, muscle mass, upper limb fat mass, and trunk fat mass were positively correlated with the femoral neck bone mineral density, total lumbar vertebra bone mineral density, and bone mineral salt content (P<0.05). In addition, thigh fat mass was positively correlated with femoral neck bone mineral density and total lumbar spine bone mineral density, whereas body fat content was negatively correlated with bone mineral salt content. CONCLUSION: Body composition was related to bone mineral density and bone mineral salt content, and the correlation between different body composition indexes, and bone mineral density, and bone mineral salt content was different.
