Abstract:
OBJECTIVE: The purpose of this study was to evaluate the performance of OSTA (Osteoporosis Self assessment Tool for Asian) in Korean peri- and postmenopausal women. DESIGN AND METHODS: Total 1488 peri- and postmenopausal women over 45 years were included from Menopause Clinic in Chung-Ang University Hospital. Femoral neck BMD was measured by using DEXA (Lunar DPXIQ #7055). Three categories of bone status were defined by BMD based on the WHO definition. OSTA index values were calculated by using only 2 components such as age and weight. Three risk categories (high, medium, low) were classified according to index values. RESULTS: Seven hundred thirty women tested comprising 49.1% of all subject had low BMD (10.6% osteoporosis, 38.5% osteopenia respectively). The combined medium and high risk groups had a high prevalence (447/557=80.3%) of low bone mass. The medium and high risk groups had 85.5% of a high specificity, and 61.2% of a good sensitivity for identifying low bone mass. The medium and high risk groups also had 87.9% of a high sensitivity, and 68.5% of a good specificity for identifying osteoporosis. CONCLUSION: OSTA is a simple tool and easy to use, because it requires only age and weight. The OSTA risk tool performed well for identifying low bone mass, especially osteoporosis in Korean peri- and postmenopausal women.
