Which of the following is a common sign of potential malnutrition in older adults?

Unintended weight loss is indeed a common sign of potential malnutrition in older adults. As individuals age, their nutritional needs change, and various factors including physiological changes, medications, and chronic conditions can impact their appetite and food intake. Unintentional weight loss can signify that an older adult is not consuming enough calories or nutrients to maintain their health, leading to weakened immunity, muscle loss, and a decline in overall health status.

Monitoring weight and dietary intake is essential in gerontological nutrition, as noticing signs of malnutrition early can facilitate timely interventions to improve nutritional status and health outcomes. In contrast, the other options, such as increased energy during physical activity, greater social engagement, and enhanced cognitive function, typically reflect positive health trends rather than indicators of nutritional deficits.
