What is the definition of significant weight loss?

The definition of significant weight loss in older adults is often quantified by specific percentages over defined periods. The correct answer outlines a criterion that is consistent with clinical guidelines typically used to assess weight loss in geriatric populations.

Specifically, the standard for significant weight loss generally includes a threshold of 5% of body weight lost within one month, which highlights the need for immediate attention. Additionally, weight loss of 7.5% over three months and 10% over six months are also widely accepted benchmarks that indicate a more gradual, yet potentially concerning, trend. These thresholds serve to inform healthcare professionals about changes in nutritional status and the risk of malnutrition or other health complications.

The choice that reflects these percentages accurately—10% over six months, 7.5% over three months, 5% over one month, and 2% over one week—aligns with evidential guidelines and provides a holistic view of significant weight changes that could impact the health of older adults. Understanding these parameters is essential for effective intervention and ongoing health monitoring in geriatric nutrition.
