Abstract
Objectives
The aim of the present study was to verify the associations between dysphagia as screened by the Eating Assessment Tool-10 (EAT-10) and indicators in the 100-mL water swallowing test (WST) or medical history among community-dwelling older people.
Study design
A cross-sectional study.
Setting and Participants
The study participants were 202 community-dwelling older Japanese adults aged ≥65 years.
Measurements
We investigated the participants’ basic attributes, including age, sex, body mass index, medical history (cerebrovascular disease, respiratory disease: chronic obstructive pulmonary disease [COPD], and history of pneumonia within the previous year), and number of prescribed medications. Dysphagia assessment was performed using the EAT-10 and the 100-mL WST as subjective and objective examinations, respectively. The 100-mL WST used four indicators (SC: swallowing capacity, VS: volume per swallow, TS: time per swallow, and choking signs). Patients with and without dysphagia according to the EAT-10 were divided into two groups according to a cutoff score of 3, and the two groups were then compared in terms of their characteristics including medical history and 100-mL WST indicators. A multiple logistic regression model was used to determine whether the indicators of the 100-mL WST or medical history were independently associated with dysphagia in the EAT-10.
Results
The multiple logistic regression analysis revealed that dysphagia in the EAT-10 was independently associated with male sex (odds ratio [OR] = 2.78; 95% confidence interval [CI] = 0.98–7.90), COPD (OR = 14.68; 95% CI = 3.14–68.85), and VS and TS in the 100-mL WST (OR = 0.85; 95% CI = 0.80–0.90 and OR = 3.03; 95% CI = 1.78–5.16, respectively).
Conclusions
Our results revealed that the EAT-10 was independently associated with the 100-mL WST and respiratory disease. We propose that swallowing rehabilitation incorporating respiratory training could be effective for older people screened using the EAT-10.
