Abstract

BACKGROUND: Osteoporosis is an important health concern among the postmenopausal women. Therefore, it is necessary to find out acceptable screening tools for osteoporotic patients. The purpose of this study was to evaluate the Risk Index by OSTA as a screening test for osteoporosis.
METHODS
The study population was 322 naturally caused menopausal women in Korea. Their was of femoral neck and lumbar spine BMD measured by DEXA. Risk Index by OSTA, based on weight and age, was calculated and the sensitivity and specificity for osteoporosis and osteopenia were evaluated. To find out the proper cut-off point for osteoporosis and osteopenia among the postmenopausal women in Korea, we also compared the sensitivity and specificity of each Risk Index value.
RESULTS
The mean age and ages at menopause were 59.1(+/-6.2) and 50.7 (+/-2.7) years, respectively. The prevalence of osteoporosis was 9.6% with femoral neck BMD. For oeteoporosis, using a cut-off point of -1 yielded a sensitivity of 74.3% and a specificity of 52.2% with femoral neck BMD. Using a cut-off of -2 yielded a sensitivity of 87.3% and a specificity of 70.9%. The ROC curve showed an AUROC 0.88 for Risk Index in identifying osteoporosis.
CONCLUSION
The Risk Index is an acceptable, simple and useful method in the diagnosis of osteoporosis with a Risk Index of -2 in Korean postmenopausal women.
