Which lifestyle interventions support bone health besides medications?

• A. Weight-bearing and resistance exercise; adequate calcium and vitamin D; smoking cessation; moderation of alcohol; home safety and fall prevention.
• B. Only calcium supplementation.
• C. Complete bed rest.
• D. High-sugar diet.

Answer: (A)

The key idea is that bone health is supported by lifestyle choices that strengthen bones, reduce bone loss, and prevent fractures. Weight-bearing and resistance exercise put mechanical load on bones, which stimulates bone formation and helps maintain or increase bone density. Adequate calcium and vitamin D provide the minerals and hormone signaling needed for proper bone remodeling and mineralization. Quitting smoking reduces harmful effects on bone turnover and improves overall bone strength, while moderating alcohol intake helps prevent further bone loss. Making homes safer and planning fall prevention lowers the chance of fractures if bones are already weakened.

Other options don’t offer this comprehensive approach: relying only on calcium misses the benefits of mechanical loading, safety measures, and lifestyle changes that protect bone health; complete bed rest itself promotes bone loss; and a high-sugar diet isn’t beneficial for bone density or fracture risk.
