概要	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. Participants without SLD at the time of a baseline survey in 2018 were followed until 2022. 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: chewing status (poor: ORs = 1.472; 95% CIs: 1.087-1.994). The results indicate that a poor chewing status was associated with SLD development after 4 years.
