Consequently, the number of older adults living alone is sharply increasing, creating an urgent social issue that necessitates comprehensive and systematic care service policies. Frailty is a key indicator of the overall health status of older adults, and because oral health and nutrition are closely linked, continuous monitoring is essential in this population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study aimed to analyze the factors influencing oral frailty and nutritional status among older adults living alone in South Korea by using an oral frailty screening tool, which is one of the recently developed function-specific frailty screening tools. A survey of 606 adults aged 65 years and older examined their sociodemographic characteristics, health status, oral health, and nutritional status. Logistic regression analysis identified key factors affecting oral frailty and nutritional status.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Results revealed a direct association between oral frailty and nutritional status, with loneliness emerging as a common factor influencing both variables.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>These findings highlight the importance of maintaining a balanced diet alongside proper oral hygiene and emphasize the need for integrated interventions including emotional support. Therefore, this study underscores the need for continuous care strategies to promote healthy aging and improve the quality of life of older adults.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnut.2025.1586860","type":"journal-article","created":{"date-parts":[[2025,6,4]],"date-time":"2025-06-04T04:15:14Z","timestamp":1749010514000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Factors affecting oral frailty and nutritional status in older adults living alone"],"prefix":"10.3389","volume":"12","author":[{"given":"Ji-Min","family":"Cha","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong Hoon","family":"Jung","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ha-neul","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hee-Sook","family":"Lim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,6,4]]},"reference":[{"key":"ref1","volume-title":"World population prospects","year":"2024"},{"key":"ref2","year":"2024"},{"key":"ref3","volume-title":"World Population Ageing 2019: Highlights","year":"2019"},{"key":"ref4","volume-title":"World population ageing 2020 highlights","year":"2020"},{"key":"ref5","volume-title":"Korea\u2019s aging speed is the fastest, but elderly poverty rate is already the highest in the OECD","year":"2024"},{"key":"ref6","volume-title":"Future Household Estimate: 2022~2052","year":"2024"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"244","DOI":"10.15709\/HSWR.2020.40.2.244","article-title":"A study on the factors influencing life satisfaction of the elderly living alone in urban areas: focused on gender and employment status","volume":"40","author":"Choi","year":"2020","journal-title":"Health Soc Welfare Rev"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"992","DOI":"10.3390\/su12030992","article-title":"Living standards in one-person households of the elderly population","volume":"12","author":"Piekut","year":"2020","journal-title":"Sustain For"},{"key":"ref9","doi-asserted-by":"publisher","first-page":"227","DOI":"10.1177\/1745691614568352","article-title":"Loneliness and social isolation as risk f9actors for mortality: a meta-analytic review","volume":"10","author":"Holt-Lunstad","year":"2015","journal-title":"Perspect Psychol Sci"},{"key":"ref10","doi-asserted-by":"publisher","first-page":"3","DOI":"10.1016\/j.ejim.2016.03.007","article-title":"Frailty measurement in research and clinical practice: a review","volume":"31","author":"Dent","year":"2016","journal-title":"Eur J Intern Med"},{"key":"ref11","doi-asserted-by":"publisher","first-page":"118","DOI":"10.1016\/j.ejim.2011.09.003","article-title":"The frailty dilemma.
