What is a primary risk factor for developing pressure ulcers among older adults?

Low hydration levels are a primary risk factor for developing pressure ulcers among older adults because adequate hydration is crucial for maintaining skin integrity and overall health. Dehydration can lead to dry, fragile skin that is more susceptible to injury and breakdown, increasing the likelihood of pressure ulcers. When skin loses moisture, it becomes less elastic and can break down more easily when subjected to pressure, such as from prolonged sitting or lying in one position.

In contrast, high dietary fat intake does not directly correlate with the risk of pressure ulcers; the issue is more related to hydration and skin condition than dietary fat. High physical activity, while beneficial for overall health, does not typically contribute to the formation of pressure ulcers; in fact, it can help improve circulation, which is protective against ulcer formation. Frequent skin moisture, if properly managed, can actually be protective, as keeping the skin well-moisturized helps maintain its barrier function and resilience. Therefore, low hydration levels are a critical focus for preventing pressure ulcers in older adults.
