Due to its complexity and multi\u2010dimensional nature, clarifying the role of oral health in the development of frailty remains challenging; potential mediating factors are being examined to improve its comprehension. This study aims to examine the relationship between frailty and oral deficits, considering biological age as a potential mediator using samples of Mexicans aged over 60.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study is a secondary analysis of the Cohort of Obesity, Sarcopenia and Frailty of Older Mexican Adults (COSFOMA), a cohort of Mexican older adults starting at age 60. We analysed pre\u2010pandemic data from 2019, including questionnaires, anthropometric measures, oral health evaluations and physical performance tests. Frailty was assessed using a standard Frailty Index, constructed from health\u2010related deficits. Oral health was evaluated with the New Oral Health Index and the Geriatric Oral Health Assessment Index (GOHAI). Accelerated aging was estimated using AnthropoAge. Associations between frailty, oral health and biological aging were examined using generalised linear models (GLMs) with bootstrapped standard errors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The analytical sample comprised 1657 participants. We found that women had higher scores in BMI categories, use of prostheses, while men had higher scores of dental biofilm, gingivitis, caries and number of missing teeth. Values were higher among those with oral health deficits. A sex\u2010stratified sub\u2010analysis was performed; among men, no statistically significant average causal mediation effect (ACME) was found. However, among women, the direct effect of oral health deficits on frailty was not statistically significant, indicating associational evidence about mediation by accelerated aging. The proportion was 51.86%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Oral health deficits were associated with frailty, evidence consistent with an indirect pathway through accelerated aging. Among women, this indirect association was primarily observed in aging profiles characterised by disproportionate fat distribution and reduced lean mass. These findings highlight potential pathways linking oral health and frailty that warrant further investigation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/ger.70086","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T05:31:03Z","timestamp":1777527063000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Mediation Analysis of Oral Health, Anthropometric Characteristics and Frailty Among Community\u2010Dwelling Mexican Older Adults"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5802-2494","authenticated-orcid":false,"given":"Julio M.","family":"Fernandez Villa","sequence":"first","affiliation":[{"name":"Unidad de Investigaci\u00f3n Epidemiol\u00f3gica y en Servicios de Salud, Area Envejecimiento, Centro M\u00e9dico Nacional Siglo XXI Instituto Mexicano del Seguro Social  Mexico City Mexico"},{"name":"Programa de Maestr\u00eda y Doctorado en Ciencias M\u00e9dicas, Odontol\u00f3gicas y de la Salud Universidad Nacional Aut\u00f3noma de M\u00e9xico, Ciudad Universitaria  Mexico City Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3093-937X","authenticated-orcid":false,"given":"Omar Yaxmehen","family":"Bello\u2010Chavolla","sequence":"additional","affiliation":[{"name":"Research Department Instituto Nacional de Geriatr\u00eda  Mexico City Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9380-6964","authenticated-orcid":false,"given":"Carmen","family":"Garcia\u2010Pe\u00f1a","sequence":"additional","affiliation":[{"name":"Research Department Instituto Nacional de Geriatr\u00eda  Mexico City Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5648-7223","authenticated-orcid":false,"given":"Sergio","family":"Sanchez\u2010Garcia","sequence":"additional","affiliation":[{"name":"Unidad de Investigaci\u00f3n Epidemiol\u00f3gica y en Servicios de Salud, Area Envejecimiento, Centro M\u00e9dico Nacional Siglo XXI Instituto Mexicano del Seguro Social  Mexico City Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,29]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamda.2015.12.016"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.18235\/0000984"},{"key":"e_1_2_11_4_1","volume-title":"An Aging World: 2015","author":"He W.","year":"2016"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41514\u2010024\u201000148\u20102"},{"issue":"3","key":"e_1_2_11_6_1","first-page":"83","article-title":"Geriatric Syndromes: Medical Misnomer or Progress in Geriatrics?","volume":"61","author":"Olde Rikkert M.
