Objective : To Find out the percentage of osteoporosis and the factors related to Bone Mineral Density (BMD) in clients who sent to investigate BMD. And To Find the magnitude of difference in the diagnosis of osteoporosis by using the value of T-Score reported by the bone densitometer compared with Thai women standard of Bone Mineral Density.

Method : This study collected data from the record of the clients who were sent for investigation of BMD in Health promotion Hospital from 1998 to 2007. 2,623 Female clients were investigated BMD by using Dual Energy X Ray Absorptionometer (DEXA) technique with Hologic QDR-4500. The variables in this study included ; age, sex, weight, height, the value of BMD and T score, the compared diagnosis of osteoporosis by using 2 methods the first method using the repon of T Score from bone densltometer and the second method using Thai women standard of bone mineral density.

Result : BMD and Osteoporosis were related to age. When the Age increased the average of BMD deceased and the percentage of osteoporosis increased. The Body Mass Index (BMl) was related to BMD. When BMI decreased the average of BMD decreased too. Using Thai women standard for diagnosis of osteoporosis instead of using T score < -2.5 reduced the diagnosis of osteoporosis to 61.3-69.6% and reduced the money spent for treatment of osteoporosis to 24.9%

Conclusion : It was suitable to use Thai women standard for diagnosis of osteoporosis, by using the value of BMD lower than 0.682 gm/cm² for diagnosis of osteoporosis of L1 -L4 spine and 0.569 gm/cm² for diagnosis of osteoporosis of femoral neck because the default values of Mean and SD in bone densitometer were higher than the Mean and SD of Thai women standard and this increased the number of cases of osteoporosis and later increased unnecessary drug usage for treatment of osteoporosis. Finally the risk factors of osteoporosis such as the increasing age, the low BMI, high calcium diet, physical inactivity, quit smoking and alcohol consumption should be considered together with BMD investigation and drug treatment of osteoporosis.
