Swallowing Changes in Community-Dwelling Older Adults

Area of Science:

• Gerontology
• Speech-Language Pathology
• Swallowing Physiology

Background:

• Aging can lead to physiological changes affecting swallowing.
• Dysphagia risk assessment is crucial in community-dwelling older adults.
• Understanding age-related swallowing differences is important for maintaining health.

Purpose of the Study:

• Identify dysphagia risk in older adults without prior diagnosis.
• Compare swallowing physiology and safety between older and younger adults.
• Investigate associations between self-ratings, VFSS findings, and swallow screen outcomes.

Main Methods:

• Recruited 32 older adults without dysphagia history.
• Administered Dysphagia Handicap Index (DHI) and a 3 oz swallow screen.
• Utilized videofluoroscopy (VFSS) for swallowing analysis and compared with younger adults' data.

Main Results:

• Older adults' DHI scores were between non-dysphagic and dysphagic norms.
• Higher oral residue scores correlated with higher likelihood of swallow screen failure.
• Older adults showed higher pharyngeal component scores on MBSImP™© than younger adults.
• No significant difference in Penetration-Aspiration Scale scores; no aspiration observed.

Conclusions:

• Swallowing measures in older individuals may reflect age-related sensory and motor changes.
• Functional swallowing and airway protection appear adequate in this non-dysphagic older cohort.
• Findings highlight the need to consider age-related physiological changes in swallowing assessment.
