五秒鐘得知自己是否為骨質疏鬆症的高風險群。
停經後女性
- 骨鬆自評指數 OSTAi index = 0.2*(體重-年齡)
- 閾值為"-1"
- 若是 OSTAi index < -1,為骨質疏鬆症的中高風險群 (約七成有骨質疏鬆症),建議進一步接受 DXA 骨質密度檢測。
50 歲以上男性
- 骨鬆自評指數 MOSTAi index = (0.3*體重)-(0.1*年齡)
- 閾值為"11"
- 若是 MOSTAi index < 11,為骨質疏鬆症的中高風險群 (約五成有骨質疏鬆症),建議進一步接受 DXA 骨質密度檢測。
舉例說明:
60 歲女性,體重 50 kg,OSTAi index = 0.2*(50-60) = -2,小於閾值"-1",故為骨質疏鬆症的中高風險群。
65 歲男性,體重 60 kg,MOSTAi index = (0.3*60)-(0.1*65) = 11.5,大於閾值"11",並非骨質疏鬆症的中高風險群。

MOSTAi = Modified Male Osteoporosis Self-Assessment Tool for Taiwan
DXA = Dual-energy X-ray Absorptiometry (雙能量X光吸收儀)
