Objectives: Osteoporosis is the most common metabolic disease of the bone, and one of the most important public health problems around the world. Obesity rate gradually increases as women grow older. The purpose of the study was to investigate the changes between bond mineral density (BMD) and body mass index (BMI) according to sex and age.
Methods: We measured the bone mineral density (BMD) of lumber spine (L2-L4)and femoral neck in 10000 normal adult, using dual energy X-ray absorptiometry (DEXA; DPX-alpha). and also measured the body mass index (BMI)in 9810 normal adult. then we analysed the changes of BMD and BMI according to sex and age.
Results: 1. As getting older, male’s T-score of lumbar spine (L2-L4) was slowly decreased. On the other hand, female’s T-score of lumbar spine was sharply dropped after 46 years old. 2. As getting older, male’s T-score of femoral was slowly decreased. On the other hand, female’s T-score of femoral was sharply dropped after 49 years old. 3. Irrespective of age, male’s BMI keep up the extent within a definite period of numerical value. As getting older, female’s BMI continued its up ward trend.
Conclusions: Much more attention should be needed for female patient suffering from osteoporosis and obesity than male.
