We examined which factors of oral function are associated with a risk for underweight among community\u2010dwelling older adults and whether regular self\u2010weighing can mitigate that risk.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a cohort study. Self\u2010administered questionnaires were mailed to 7665 older adults in March 2019 (response rate 74.3%) and 7591 in March 2020 (response rate 74.7%). Among those who responded to both surveys, 3594 older adults who were not underweight in March 2019 were included (follow\u2010up rate: 59.2%). We examined the association between dysphagia, poor masticatory function, and dry mouth and the development of underweight, and whether regular self\u2010weighing reduced the risk for underweight.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The average age\u00a0\u00b1\u00a0standard deviation of participants was 71.1\u00a0\u00b1\u00a03.4 years.
