An older adult is defined as which of the following?

• A. Older than 65.
• B. Older than 60.
• C. 65 to 74 years old.
• D. 75 and older.

Answer: (A)

The commonly used definition for an older adult in geriatric nutrition is 65 years and older. This threshold aligns with traditional retirement ages and many guideline frameworks, including Medicare eligibility in the U.S., providing a consistent cutoff for risk assessment, screening, and care planning. The other options are not as inclusive: defining someone as older than 60 broadens the group beyond the typical threshold; 65 to 74 only covers the younger subset of older adults and excludes those 75 and older; and 75 and older focuses on the oldest subset rather than the whole older-adult population.
