Subgroup analyses and tests for interaction were employed to investigate potential effect modification and assess the robustness of the observed associations. Sensitivity analysis was conducted to compute E\u2010values for quantifying unmeasured confounding effects and assessing association robustness. Additionally, mediation analysis was conducted to assess the indirect pathways.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      After adjustment for all covariates, higher FTUs were inversely associated with osteoporosis prevalence (OR\u2009=\u20090.93, 95% CI: 0.89\u20130.98,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.004). Furthermore, a significant dose\u2013response relationship was observed: participants in the highest FTU tertile (6\u20138) had a 46% lower risk of osteoporosis compared to those in the lowest tertile (0\u20131) (OR\u2009=\u20090.54, 95% CI: 0.39\u20130.76,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001). Both subgroup and sensitivity analyses confirmed the robustness of these findings. Mediation analysis further revealed that Food Variety Score (FVS) and Geriatric Nutritional Risk Index (GNRI) mediated 7.96% and 6.27% of the association between FTUs and osteoporosis, respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study confirms that better masticatory function, measured by FTUs, is significantly associated with a lower risk of osteoporosis, a link partially explained by improved food variety (FVS) and nutritional status (GNRI). Maintaining adequate masticatory function may therefore be related to a reduced incidence of osteoporosis, possibly through its supportive role in nutritional health. This study highlights the potential of oral health preservation in preventing osteoporosis. Further prospective studies are needed to confirm the causal relationship and optimize clinical intervention.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/joor.70193","type":"journal-article","created":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T12:37:32Z","timestamp":1774960652000},"page":"1381-1393","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Food Variety Score and Geriatric Nutritional Risk Index Mediate the Relationship Between Masticatory Function and Osteoporosis"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-3943-477X","authenticated-orcid":false,"given":"Ruliu","family":"Xiong","sequence":"first","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingmao","family":"Zhou","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"},{"name":"Zhongshan Hospital of Traditional Chinese Medicine  Guangdong China"},{"name":"The Eighth Clinical Medical College of Guangzhou University of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengji","family":"Liu","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Li","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xing","family":"Chen","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhixiong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zixuan","family":"Hong","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lili","family":"Sang","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"},{"name":"Zhongshan Hospital of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhijie","family":"Zeng","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"},{"name":"Zhongshan Hospital of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nan","family":"Yang","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"},{"name":"Zhongshan Hospital of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoling","family":"Sun","sequence":"additional","affiliation":[{"name":"Zhongshan Hospital of Traditional Chinese Medicine Affiliated to Guangzhou University of Traditional Chinese Medicine  Guangdong China"},{"name":"Zhongshan Hospital of Traditional Chinese Medicine  Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,31]]},"reference":[{"key":"e_1_2_12_2_1","volume-title":"Ageing and Health:The Politics of Better Policies","author":"Sl G.","year":"2022"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm14165785"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/jbmr.5650090802"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00198\u2010006\u20100172\u20104"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mcna.2020.06.004"},{"issue":"1","key":"e_1_2_12_7_1","first-page":"105","article-title":"The Epidemiology of Osteoporosis","volume":"133","author":"Clynes M.
