“…A previous study, however, only showed preliminary results in this regard because it was focused on the assessment of swallowing biomechanical variables; it did not examine underlying factors such as comorbidities, activities of daily living (ADL), and physical and oral functions, which are frequently associated with the physiology of swallowing [9]. Another study reported a relationship between JOF and dysphagia [10]. However, the study collected data only from participants with cerebrovascular diseases, and factors of muscle strength such as tongue pressure (TP) and hand grip strength (HGS) were not considered.…”

Introduction: Jaw-opening force (JOF) can be a potential screening tool for dysphagia. However, confounding variables such as comorbidities or physical and oral functions that are associated with the physiology of swallowing have not previously been examined. Adjusting for these variables could reveal the relationship between JOF and dysphagia and indicate whether JOF is an independent factor associated with dysphagia. We therefore aimed to assess the efficacy of using JOF for dysphagia screening in this multi-institutional study. Methods: Community-dwelling older adults over the age of 65 years (N = 403) who visited the university dental hospitals and participated in health surveys (mean age ± standard deviation, 77.1 ± 7.0 years; range, 65–96 years) between November 2018 and January 2020 were included in this study. The JOFs of all participants were measured. The measured JOF was compared with the presence of dysphagia, which was defined using the Functional Oral Intake Scale and the Eating Assessment Tool-10. Results: Multiple logistic regression analysis revealed that the presence of dysphagia was independently associated with JOF, calf circumference, and dependence after adjusting for age and sex. Discussion/Conclusion: Decreased JOF can be a risk factor for dysphagia in older adults.
