Abstract
Background: Older adults have decreased swallowing-related muscle mass, which may lead to decreased swallowing function. One of the causes of this decrease in muscle mass in older adults is a decrease in swallowing frequency.
Objective: The purpose of this study was to evaluate the relationship between swallowing frequency and swallowing-related muscle mass.
Methods: The study included 84 older adults residing in long-term care beds or elderly care facilities. The correlation between swallowing frequency measured by detecting swallowing sounds from laryngeal sounds and the coronal cross-sectional area of the geniohyoid muscle (GM) measured using an ultrasound diagnostic device was examined. Additionally, multiple regression analysis was used to examine the relationship between GM muscle mass and factors that may influence muscle mass, including sex, age, nutrition (body mass index), total body muscle mass (thigh muscle thickness [TMT]) and swallowing frequency.
Results: A significant positive correlation (r = 0.437, p < 0.001) was found between swallowing frequency and GM mass. A multivariate analysis including other factors revealed that sex (β = 0.482, p < 0.001), TMT (β = 0.272, p < 0.005) and swallowing frequency (β = 0.193, p < 0.05) were significantly correlated with GM mass.
Conclusion: The results of this study indicated that GM mass differed by sex and was correlated with whole-body muscle mass; furthermore, the findings suggest that it is also influenced by localised activity, specifically swallowing frequency.
期刊介绍：
Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function.
Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology.
The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
