To evaluate the bone mineral density (BMD) and biochemical markers. We evaluated the BMD of femoral neck and lumbar spines of 998(male 568, female 430) persons who took a regular health screening in Woosuk University Hospital from September 2007 to March 2008 by dual energy bone mineral densitometry. Results of BMD are different in terms of biochemical markers. Especially aged people showed osteoporotic change progressively. Degree of osteoporosis increases with age. A steep decrease of BMD can be found in postmenopausal women who have low level of female hormone. More persistent effort is needed to find out the factors that can reduce BMD values for prevention of problems by osteoporosis. In essence, research on factors related to other biochemical markers must be studied continuously.
