Which of the following is a risk factor for osteoporosis in women?

• A. White or Asian females under 127 lb with a history of fracture
• B. Regular weight-bearing exercise
• C. Adequate estrogen levels
• D. Calcium supplementation

Answer: (A)

Osteoporosis risk rises when factors lower bone mass or indicate fragility. White or Asian women have a higher risk compared with other groups, and a small, light body frame means less bone to begin with. A history of fracture—especially from low trauma—signals weakened bones and strongly predicts future fractures. These elements together identify a high-risk profile for osteoporosis.

The other factors described are protective. Regular weight-bearing exercise helps build and maintain bone, adequate estrogen preserves bone density, and calcium supplementation supports bone mineralization—none of these increase risk.
