Maintaining 20 teeth is a challenge for this age group. The co\u2010occurrence of health\u2010risk behaviours is common and has been linked to an increased risk of multiple chronic diseases, including tooth loss.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and Methods<\/jats:title><jats:p>A cross\u2010sectional analysis of wave 7 of the English Longitudinal Study of Ageing (ELSA) was conducted. Functional dentition was self\u2010reported as having 20 or more teeth. Four health\u2010related behaviours (smoking, alcohol intake, fruit and vegetable consumption, and physical activity) were analysed to investigate their association with functional dentition. Demographic characteristics (sex, age, ethnicity) and socioeconomic factors (education, wealth) were included as covariates. Latent Class Analysis (LCA) was conducted using four dichotomised behaviour variables to identify clusters of behaviours. Logistic regression modelling was used to examine the association between clusters of health\u2010related behaviours and functional dentition. The model was adjusted for demographic and socioeconomic factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 7783 participants were included. The LCA model identified three clusters: (1) risky, (2) moderate and (3) healthy. In the fully adjusted logistic regression model, the odds of having a functional dentition were 1.42 higher among those in the moderate cluster (95% CI: 1.23, 1.65), and 1.70 higher among those in the healthy cluster (95% CI: 1.39, 2.09) than for participants in the risky cluster.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Risky behaviours tend to cluster among older adults. Engaging in multiple risky behaviours is associated with having fewer than 20 teeth. Initiatives and public health campaigns that focus on these clustering patterns, as well as the underlying factors, could benefit both oral and general health.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ger.12807","type":"journal-article","created":{"date-parts":[[2025,1,8]],"date-time":"2025-01-08T06:09:42Z","timestamp":1736316582000},"page":"396-404","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Health\u2010Related Behaviour Clusters and Functional Dentition in Older People"],"prefix":"10.1111","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-0590-8291","authenticated-orcid":false,"given":"Fatimah","family":"Alobaidi","sequence":"first","affiliation":[{"name":"Faculty of Dentistry, Oral &amp; Craniofacial Sciences King's College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4609-0991","authenticated-orcid":false,"given":"Ellie","family":"Heidari","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Oral &amp; Craniofacial Sciences King's College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6339-9480","authenticated-orcid":false,"given":"Wael","family":"Sabbah","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Oral &amp; Craniofacial Sciences King's College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,1,8]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"1","article-title":"Recent Advances in Oral Health.
