One of the causes of this decrease in muscle mass in older adults is a decrease in swallowing frequency.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n The purpose of this study was to evaluate the relationship between swallowing frequency and swallowing\u2010related muscle mass.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n The study included 84 older adults residing in long\u2010term care beds or elderly care facilities. The correlation between swallowing frequency measured by detecting swallowing sounds from laryngeal sounds and the coronal cross\u2010sectional 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.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A significant positive correlation (\n r<\/jats:italic>\n \u2009=\u20090.437,\n p<\/jats:italic>\n \u2009<\u20090.001) was found between swallowing frequency and GM mass. A multivariate analysis including other factors revealed that sex (\n \u03b2<\/jats:italic>\n \u2009=\u20090.482,\n p<\/jats:italic>\n \u2009<\u20090.001), TMT (\n \u03b2<\/jats:italic>\n \u2009=\u20090.272,\n p<\/jats:italic>\n \u2009<\u20090.005) and swallowing frequency (\n \u03b2<\/jats:italic>\n \u2009=\u20090.193,\n p<\/jats:italic>\n \u2009<\u20090.05) were significantly correlated with GM mass.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The results of this study indicated that GM mass differed by sex and was correlated with whole\u2010body muscle mass; furthermore, the findings suggest that it is also influenced by localised activity, specifically swallowing frequency.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/joor.70056","type":"journal-article","created":{"date-parts":[[2025,9,9]],"date-time":"2025-09-09T12:24:57Z","timestamp":1757420697000},"page":"42-49","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Relationship Between Swallowing Frequency and Swallowing\u2010Related Muscle Mass in Older Adults"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2616-6394","authenticated-orcid":false,"given":"Haruna","family":"Kawamichi","sequence":"first","affiliation":[{"name":"Division of Oral and Facial Disorders The University of Osaka Dental Hospital Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aya","family":"Obana","sequence":"additional","affiliation":[{"name":"Division of Oral and Facial Disorders The University of Osaka Dental Hospital Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kanji","family":"Nohara","sequence":"additional","affiliation":[{"name":"Division of Functional Oral Neuro Science, Graduate School of Dentistry The University of Osaka Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobukazu","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Division of Oral and Facial Disorders The University of Osaka Dental Hospital Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takayoshi","family":"Sakai","sequence":"additional","affiliation":[{"name":"Division of Functional Oral Neuro Science, Graduate School of Dentistry The University of Osaka Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,9]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afp100"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1001\/archoto.2010.129"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/0884533609332005"},{"key":"e_1_2_10_5_1","first-page":"18","article-title":"Age\u2010Related Changes in Geniohyoid Muscle Morphology Predict Reduced Swallowing Function","volume":"30","author":"Baba T.","year":"2017","journal-title":"Journal of Oral Health and Biosciences"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/joor.13439"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/gls225"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40520-021-01859-2"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00455-020-10095-1"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/joor.12936"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.2147\/CIA.S132940"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.3945\/ajcn.2010.28608A"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2013-1502"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/0003-9969(65)90060-9"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/joor.12085"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12887-022-03547-0"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2842.2012.02293.x"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00455-012-9416-y"},{"key":"e_1_2_10_19_1","unstructured":"Audacity \u201cAudacity: The Free Cross\u2010Platform Sound Editor \u201daccessed December 3 2023 http:\/\/audacity.sourceforge.net."},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.00467.2013"},{"issue":"7","key":"e_1_2_10_21_1","first-page":"36","article-title":"Image Processing With ImageJ","volume":"11","author":"Abramoff M.
