Why is vitamin D deficiency a concern for older adults in relation to falls?

• A. Vitamin D deficiency is associated with poorer bone health and higher fall risk.
• B. It has no impact on fall risk.
• C. It only affects vision.
• D. Vitamin D deficiency improves bone density.

Answer: (A)

Vitamin D status influences both bone strength and muscle function, which are key for preventing falls in older adults. When vitamin D is lacking, calcium absorption drops, bones can become weaker, and muscles may lose strength, all of which raise the likelihood of losing balance and falling. That’s why vitamin D deficiency is linked to poorer bone health and a higher fall risk. The other statements aren’t accurate—deficiency does impact fall risk beyond vision, it doesn’t improve bone density, and it isn’t without effect. Ensuring adequate vitamin D through sunlight, diet, and supplementation as advised can help support bone integrity and balance in aging populations.
