Abstract:

BACKGROUND: Bone mineral density is used for the diagnosis of osteoporosis, and bone mineral density is related to genetic, environment and fat distribution factors. Dual energy X-ray absorptiometry and quantitative CT are main methods of measuring bone mineral density.

OBJECTIVE: To investigate the relationship between lumbar spine bone mineral density and fat distribution in young adults by quantitative CT.

 

METHODS: Totally 262young adults aged 20-40 years in Beijing urban and suburb areas were screened based on inclusion and exclusion criteria, and all volunteers provided written informed consents. Quantitative CT was used to measure the intra-abdominal fat area, subcutaneous fat area and total abdominal fat area of L2-L4 bone mineral density and L4 vertebrae. The relationship between bone mineral density and fat distribution was analyzed by Pearson correlation analysis and multivariate linear regression.
RESULTS AND CONCLUSION: (1) The area of intra-abdominal fat was negatively correlated with bone mineral density in young adults in Beijing (P < 0.05). (2) The area of subcutaneous fat and total abdominal fat were not correlated with bone mineral density. (3) Therefore, it is suggested to measure the bone mineral density of lumbar spondylous bone in young people and control obesity, so as to prevent osteoporosis and make early diagnosis.
