Swallowing Problems in Seniors Predict Frailty, Study Reveals
A recent study highlights the link between swallowing difficulties and the onset of frailty in older adults, providing crucial insights for proactive health management. The research underscores how seemingly minor physical challenges can significantly impact an individual’s overall well-being.
Swallowing Issues Significantly Raise Frailty Risk
Research involving nearly 800 elderly individuals in Japan has revealed that impaired swallowing function can significantly increase the likelihood of developing frailty. The study, published in BMC Geriatrics, followed participants aged 65 and older for two years. The results show a strong correlation between swallowing difficulties and the progression of frailty, with those experiencing swallowing problems facing a heightened risk.
The study found that deteriorating swallowing function (DSF) was present in almost half of the participants at the outset. DSF was determined through adverse results in tests assessing saliva swallowing frequency, tongue pressure, and self-reported difficulties with liquids. This all-encompassing definition reflects the range of ways these issues can arise in older adults.
Gender Differences and Menopause’s Role
The study also identified noteworthy gender differences in swallowing function. Women exhibited notably lower tongue pressure and fewer saliva swallows compared to men. The researchers suggest that hormonal changes during menopause might contribute to these variances in the muscles and neural control needed for swallowing.

According to the National Council on Aging, frailty affects approximately 10% of adults aged 65 and older. Frailty can lead to falls, hospitalization, and a decline in independence (NCOA, 2024).
Methodology and Key Findings
The research assessed swallowing function via three methods: counting the number of saliva swallows in 30 seconds, measuring tongue pressure strength, and asking about self-reported liquid swallowing difficulties. Participants with adverse criteria on any of these measures were categorized as having deteriorating swallowing function.
During the two-year follow-up, 149 participants (18.7%) experienced worsening frailty. Notably, 22.4% of those with swallowing issues at the start of the study saw their frailty worsen compared to those without swallowing difficulties.
These findings stayed significant even after accounting for factors like age, weight, physical function, and cognitive ability. This supports the idea that swallowing problems represent an independent risk factor for frailty in older adults.
