Which of the following is part of universal osteoporosis prevention besides Calcium and Vitamin D supplementation?

• A. Weight-bearing exercises
• B. Calcitonin injections
• C. Teriparatide
• D. Risedronate

Answer: (A)

Weight-bearing exercises are a cornerstone of universal osteoporosis prevention because mechanical loading stimulates bone formation and helps maintain bone density. When bones are regularly challenged by bearing weight or resisting forces, osteoblast activity increases and bone mass is preserved, which lowers fracture risk. These activities also improve muscle strength and balance, reducing the chances of falls—the other major cause of fractures in older adults. While calcium and vitamin D are important for bone health, they work best when paired with activity that provides a stimulus to bone. The other options are pharmacologic treatments reserved for people with established osteoporosis or high fracture risk, not universal preventive measures for everyone. Calcitonin injections, teriparatide, and risedronate have specific indications, dosing, and safety considerations and are not used as general prevention for the entire population.
