kn-abstract=Background/Objectives: In this longitudinal study, the relationship between chewing status and steatotic liver disease (SLD) was examined in 3775 people aged ≥50 years who underwent medical checkups at Junpukai Health Maintenance Center in Okayama, Japan. Methods: Participants without SLD at the time of a baseline survey in 2018 were followed until 2022. Chewing status was assessed by a self-administered questionnaire. The presence or absence of SLD was ascertained from the medical records of Junpukai Health Maintenance Center. Results: A total of 541 participants (14%) were diagnosed as having a poor chewing status at baseline. Furthermore, 318 (8%) participants were newly diagnosed with SLD at follow-up. In multivariate logistic regression analyses, the presence or absence of SLD was found to be associated with the following characteristics at baseline: sex (male: odds ratio [ORs] = 1.806; 95% confidence interval [CIs]: 1.399–2.351), age (ORs = 0.969; 95% CIs: 0.948–0.991), body mass index (≥25.0 kg/m2; ORs = 1.934; 95% CIs: 1.467–2.549), diastolic blood pressure (ORs = 1.017; 95% CIs: 1.002–1.032), and chewing status (poor: ORs = 1.472; 95% CIs: 1.087–1.994). Conclusions: The results indicate that a poor chewing status was associated with SLD development after 4 years. Aggressively recommending dental visits to participants with poor chewing status may not only improve their ability to chew well but may also reduce the incidence of SLD.
