ObjectiveThis study was carried out to determine the prevalence of suspected dysphagia and its features in both independent and dependent older people living at home.Materials and methodsThe 10-Item Eating Assessment Tool (EAT-10) questionnaire was sent to 1,000 independent older people and 2,000 dependent older people living at home in a municipal district of Tokyo, Japan. The participants were selected by stratified randomization according to age and care level. We set the cut-off value of EAT-10 at a score of ≥3. The percentage of participants with an EAT-10 score ≥3 was defined as the prevalence of suspected dysphagia. The chi-square test was used for analyzing prevalence in each group. Analysis of the distribution of EAT-10 scores, and comparisons among items, age groups, and care levels to identify symptom features were performed using the Kruskal-Wallis test and Mann-Whitney U test.ResultsValid responses were received from 510 independent older people aged 65 years or older (mean age 75.0 ± 7.2) and 886 dependent older people (mean age 82.3 ± 6.7). The prevalences of suspected dysphagia were 25.1% and 53.8%, respectively, and showed significant increases with advancing age and care level. In both groups, many older people assigned high scores to the item about coughing, whereas individuals requiring high-level care assigned higher scores to the items about not only coughing but also swallowing of solids and quality of life.ConclusionIn independent people, approximately one in four individuals showed suspected dysphagia and coughing was the most perceivable symptom. In dependent people, approximately one in two individuals showed suspected dysphagia and their specifically perceivable symptoms were coughing, difficulties in swallowing solids and psychological burden.

Objectives:The aim of the present study was (a) to determine the relationship of videofluoroscopic swallowing study (VFSS) findings of the swallowing musculature with the diagnostic criteria for sarcopenic dysphagia and (b) to examine the usefulness of VFSS for diagnosing sarcopenic dysphagia. Methods:The participants were 132 patients (mean age, 80.4 ± 8.8 years). Their skeletal muscle mass, nutritional status and swallowing functions as assessed by VFSS findings were measured. Also, the relationship between the VFSS findings and sarcopenia was examined.Results: Of all the participants, 20 men (mean age, 83.2 ± 6.9 years) and 27 women (mean age, 85.3 ± 6.9 years) were diagnosed with sarcopenia. In men, the amount of laryngeal upward movement (ALUM) was significantly lower and the pharyngeal area was significantly wider in the sarcopenia group than in the non-sarcopenia group.In women, the pharyngeal area was significantly wider in the sarcopenia group than in the non-sarcopenia group. In a logistic regression model, ALUM (odds ratio [OR] 1.135, 95% confidence interval [CI] 1.037-1.241, P = .006) and pharyngeal area (OR 0.028, 95% CI 0.001-0.670, P = .027) was a significant independent factor for the presence or absence of sarcopenia. Conclusions: The decline in swallowing function of sarcopenia patients was characterised by lower laryngeal movement and enlargement of the pharyngeal cavity due to decreased skeletal muscle mass and decreased muscle strength. The present study suggested the usefulness of measuring ALUM during swallowing and measuring the pharyngeal area with VFSS as indicators of decreased swallowing muscle function in sarcopenia.

Objective We considered the effect of dysphagia rehabilitation and investigated parameters associated with the resumption of oral intake in the elderly patients receiving home nursing care who were not eating by mouth. Methods The participants were 116 patients aged ≥65 years (66 men and 50 women, mean age 79.7 ± 8.9 years) who were receiving home nursing care and not eating by mouth because of dysphagia. All patients underwent dysphagia rehabilitation for 6 months with the objective of resuming oral intake. After 6 months of dysphagia rehabilitation, the patients’ eating status was assessed using the Functional Oral Intake Scale (FOIS) and the associations of the post‐intervention FOIS score with age, history of pneumonia, duration of enteral nutrition, body mass index (BMI), alertness, physical function (ability to walk) and swallowing function at the initial examination. Results Functional Oral Intake Scale scores increased significantly after 6 months rather than those at the initial evaluation ( P < .001). Eighty patients (69.0%) resumed oral intake (FOIS score ≥2), thirty patients (25.9%) of whom became capable of daily oral intake (FOIS score ≥3). Swallowing function was associated with the resumption of oral intake. In addition, physical function before dysphagia rehabilitation was an important factor to resume daily oral intake. Conclusions The results of the present study suggest that the resumption of oral intake by patients receiving enteral nutrition requires improvement in swallowing function. In addition, anyone who cannot walk may not recover daily oral intake.

ObjectiveThis study aimed to clarify the relationship between the oral intake function and functional status, as well as to determine the aspects of functional status potentially predicting the effects of dysphagia rehabilitation in the maintenance stage, in elder outpatients.MethodsThis study was conducted in a clinic, specialised in rehabilitation of patients with dysphagia. The participants were 93 non–tube‐fed patients 65 years of age or older. The participants were scheduled to undergo the initial examination for oral intake function and functional status, and then to receive dysphagia rehabilitation for 1 year. After rehabilitation period, oral intake function was re‐evaluated, and the elements of functional status potentially related to the effects of dysphagia rehabilitation were determined.ResultsIt was found that the lower the participants’ oral intake function levels, the higher the prevalence of reduced parameters of functional status. After 1‐year dysphagia rehabilitation, the oral intake function was maintained or improved in 70 (75.3%) participants, but had diminished in 23 (24.7%). Our analysis revealed that participants with higher Vitality Index scores and MMSE at the time of initial examination were significantly more likely to show maintained or improved oral intake function at 1 year (odds ratio[OR], 1.76; 95% confidence interval [CI], 1.14‐2.71; OR, 1.17; 95% CI, 1.06‐1.28, respectively).ConclusionsIt became apparent that the lower the oral intake function level at the initial examination, the higher the prevalence of reduced multidimensional functional status. Mental function was found to predict the effects of dysphagia rehabilitation in the maintenance stage.
