Which nutrition-related factor can contribute to pressure ulcers?

• A. Protein deficiency
• B. Vitamin D sufficiency
• C. Adequate Hydration
• D. Regular Exercise

Answer: (A)

Protein intake provides the building blocks for tissue repair and skin integrity. When protein is deficient, the body’s ability to synthesize collagen, create new tissue, and support immune function is impaired, delaying wound healing and weakening the skin’s resilience under pressure. This makes older adults especially susceptible to developing pressure ulcers and to slower healing once ulcers form.

While hydration, mobility, and overall energy status influence ulcer risk, the nutrition-related factor most directly tied to both the development and healing of pressure ulcers is insufficient protein. Ensuring adequate high-quality protein intake supports wound repair processes and helps maintain skin integrity, reducing ulcer risk and promoting recovery.
