This study examined lip seal strength and tongue pressure among Japanese male workers by age. A self-administered questionnaire survey including alcohol consumption and smoking was conducted on 454 male workers. Height, weight, lip seal strength, and tongue pressure were also measured and then stratified by age (20s, 30s, 40s, 50s, and 60s and over). The mean (25th, 75th percentiles) lip seal strength and tongue pressure for all workers were 13.7 N (11.6, 16.4) and 41.7 kPa (35.2, 48.2), respectively. Both lip seal strength and tongue pressure were lowest in the 20s, at 12.1 N (9.6, 14.0) and 40.6 kPa (33.4, 47.6), respectively. The multiple regression analysis adjusted for smoking showed a significant positive association between lip seal strength and BMI for the 20s, 50s, and 60s and over, and a significant positive association between tongue pressure and BMI for the 30s, 40s, 50s, and 60s and over. To maintain oral health in older adults, it may be useful to measure workers\u2019 lip seal strength and tongue pressure and intervene at an earlier stage.<\/jats:p>","DOI":"10.3390\/ijerph20042862","type":"journal-article","created":{"date-parts":[[2023,2,7]],"date-time":"2023-02-07T01:56:48Z","timestamp":1675735008000},"page":"2862","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Lip Seal Strength and Tongue Pressure among Japanese Male Workers: Comparison of Different Age Groups"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9805-508X","authenticated-orcid":false,"given":"Akira","family":"Minoura","sequence":"first","affiliation":[{"name":"Department of Hygiene, Public Health and Preventive Medicine, School of Medicine, Showa University, Tokyo 142-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiaki","family":"Ihara","sequence":"additional","affiliation":[{"name":"Division of Oral Functional Rehabilitation Medicine, Department of Special Needs Dentistry, School of Dentistry, Showa University, Tokyo 145-8515, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirotaka","family":"Kato","sequence":"additional","affiliation":[{"name":"Division of Oral Functional Rehabilitation Medicine, Department of Special Needs Dentistry, School of Dentistry, Showa University, Tokyo 145-8515, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kouzou","family":"Murakami","sequence":"additional","affiliation":[{"name":"Department of Radiology, Division of Radiation Oncology, School of Medicine, Showa University, Tokyo 142-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5091-8210","authenticated-orcid":false,"given":"Yoshio","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine and Allergology, Department of Medicine, School of Medicine, Showa University, Tokyo 142-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4466-7953","authenticated-orcid":false,"given":"Kojiro","family":"Hirano","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Head and Neck Surgery, School of Medicine, Showa University, Tokyo 142-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshinori","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Radiology, Division of Radiation Oncology, School of Medicine, Showa University, Tokyo 142-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2252-3542","authenticated-orcid":false,"given":"Akatsuki","family":"Kokaze","sequence":"additional","affiliation":[{"name":"Department of Hygiene, Public Health and Preventive Medicine, School of Medicine, Showa University, Tokyo 142-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"313","DOI":"10.1111\/joor.12486","article-title":"Oro-facial impairment in stroke patients","volume":"44","author":"Schimmel","year":"2017","journal-title":"J.
