The second sample consisted of middle\u2010aged workers aged \u2265\u200940\u2009years employed at municipal offices in Fukuoka. Survey items included tongue coating index, mucosal wetness, occlusal force, oral diadochokinesis, tongue pressure, masticatory function, swallowing function and the prevalence of oral hypofunction. Trend tests and binary logistic regression analysis were conducted. The dependent variable was the presence of oral hypofunction, and the independent variable was the age group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Our analysis included 645 participants (275 men and 370 women, aged 40\u201389\u2009years).

The prevalence of oral hypofunction was higher in the 80s (adjusted odds ratio: 3.4, 95% confidence interval: 1.4\u20138.3) than in the reference category (60s).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Expanding middle\u2010aged participant data and conducting longitudinal studies are essential for understanding age\u2010related changes in oral function.
