The disease Paget's disease is associated with which risk factors?

• A. Cat ownership and male sex
• B. Vitamin D deficiency
• C. Regular exercise
• D. Low calcium diet

Answer: (A)

Paget disease of bone tends to affect older adults and is more common in men, with family history and certain ancestries increasing risk. Among the options, male sex aligns with this established association, making it a true risk factor. The other items—vitamin D deficiency, regular exercise, and a low calcium diet—do not have recognized links to Paget disease. Cat ownership is not a known risk factor. So the concept being tested is recognizing which factors actually relate to Paget disease, with male sex being the real risk factor in this set.
