Older adults with sarcopenia face more oral health and swallowing challenges
Sarcopenia affects oral health and swallowing in older patients: understand the clinical links for comprehensive care.
Older adults with sarcopenia (age-related muscle loss and weakness) experience greater limitations in oral health, nutrition, and swallowing function compared to peers without sarcopenia, according to a clinical study by Yücel et al. (2025). When sarcopenia affects muscles in the orofacial system, it increases the risk of dysphagia and aspiration, particularly in combination with illness and medication use. Poor oral health and swallowing difficulty can worsen nutritional status in older adults.
What the study found about oral health and swallowing
Researchers recruited 65 older adults (28 with sarcopenia, 37 without) between May 2021 and May 2022. The sarcopenia group had a mean age of 82 years; the non-sarcopenia group averaged 80 years. Participants with sarcopenia reported significantly worse oral health-related quality of life on the OHIP-14 scale, particularly in pain and psychosocial domains. On the Eating Assessment Tool-10 (EAT-10), the sarcopenia group had a median score of 5 compared to 2 in the non-sarcopenia group, with 79% of the sarcopenia group scoring 3 or above (the threshold for abnormal swallowing) versus 40% of the non-sarcopenia group.
Nutritional status differences between groups
Nutritional assessment using the Mini Nutritional Assessment (MNA) revealed stark differences. In the sarcopenia group, 68% faced malnutrition risk and 11% were actually malnourished. Among those without sarcopenia, 54% had malnutrition risk and 0% were malnourished. The researchers confirmed their hypothesis that older adults with sarcopenia experience more constraints across oral health, nutrition, and swallowing than those without sarcopenia. However, they noted study limitations including small sample size, subjective measurement tools, lack of long-term follow-up, and exclusion of older adults with certain physical impairments that are actually characteristic of sarcopenia.
Frequently asked questions
What is sarcopenia and how does it affect the mouth and swallowing?
Sarcopenia is age-related loss of muscle mass and strength that can also affect muscles in the orofacial system and those involved in swallowing. When these muscles are affected by sarcopenia, it increases the risk of dysphagia (swallowing difficulty) and aspiration, especially when combined with illness or medication use.
How much worse is swallowing function in older adults with sarcopenia?
In the Yücel study, 79% of older adults with sarcopenia had abnormal swallowing scores on the EAT-10 scale compared to 40% without sarcopenia. The sarcopenia group had a median EAT-10 score of 5 versus 2 in the non-sarcopenia group.
What percentage of older adults with sarcopenia are malnourished?
In the study, 68% of older adults with sarcopenia faced malnutrition risk and 11% were actually malnourished, compared to 54% at risk and 0% malnourished in the non-sarcopenia group.
Does sarcopenia worsen oral health-related quality of life?
Yes. Older adults with sarcopenia reported significantly worse oral health-related quality of life on the OHIP-14 scale, with particular problems in pain and psychosocial domains compared to those without sarcopenia.
What tools did researchers use to assess swallowing and nutrition in this study?
Researchers used the Eating Assessment Tool-10 (EAT-10) to assess swallowing function, the Mini Nutritional Assessment (MNA) to evaluate nutritional status, and the OHIP-14 scale to measure oral health-related quality of life.
