However, adhesiveness is an equally significant property that can affect swallowing function, even in semi-solid foods with similar levels of viscosity. The purpose of this study was to classify the adhesiveness of food into stages and determine whether these classifications are relevant to swallowing function. Methods: This study included 30 healthy elderly adults aged 65 years. After categorizing adhesiveness into three levels based on the results of the sensory test, 30 participants were asked to swallow representative foods at each level. A videofluoroscopic swallowing study (VFSS) was performed to determine the presence or absence of pharyngeal residues based on the level of adhesiveness. The chi-square test was used to verify whether there was a difference in remnants according to the level of adhesiveness, and significance was judged with a p-value of less than 0.05. Results: Adhesiveness was categorized into three distinct levels: level 1 (0\u20134 mJ), level 2 (4\u201318 mJ), and level 3 (&gt;18 mJ). Upon examining the subjects presenting with residual material, we observed three cases of level 1 adhesiveness, 16 cases of level 2, and 25 cases of level 3. The chi-square test was used to assess the statistical significance between the levels, revealing a significant difference with a p-value &lt; 0.0001. Conclusions: We presented the level of adhesiveness by dividing it into three stages and proved that it is meaningful in relation to the swallowing function. Selecting and recommending foods with an appropriate level of adhesiveness will help enhance swallowing safety in older adults.<\/jats:p>","DOI":"10.3390\/geriatrics9020048","type":"journal-article","created":{"date-parts":[[2024,4,9]],"date-time":"2024-04-09T08:55:12Z","timestamp":1712652912000},"page":"48","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Assessing Adhesiveness Levels in a Dysphagia Diet for Older Adults"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4234-6137","authenticated-orcid":false,"given":"Tae-Heon","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Dongguk University Ilsan Hospital, Goyang-si 10321, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4989-2575","authenticated-orcid":false,"given":"Jin-Woo","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, Dongguk University Ilsan Hospital, Goyang-si 10321, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"212","DOI":"10.1111\/nmo.12467","article-title":"Prevalence and risk factors for dysphagia: A USA community study","volume":"27","author":"Cho","year":"2015","journal-title":"Neurogastroenterol.
