OBJECTIVES: To survey oral status in detail and clarify the factors associated with nutritional status as evaluated by the Mini Nutritional Assessment.
BACKGROUND: Malnutrition is common in older adults and increases the risk of frailty, sarcopenia, and mortality. However, few longitudinal studies have been performed to investigate the causal effect of oral status on malnutrition in detail, and the information reported in those longitudinal studies has been limited to dentition status and swallowing ability.
MATERIALS AND METHODS: The participants in this prospective cohort study were patients who visited the Preventive Dentistry Clinic at Okayama University Hospital from November 2017 to January 2021. The number of teeth, periodontal condition, oral function (oral diadochokinesis, masticatory ability, number of bacteria in tongue coating, occlusal force, oral moisture, tongue pressure, swallowing function), nutritional status, the number of comorbidities, and mental health status were examined. These variables were analysed using structural equation modelling (SEM).
RESULTS: The final analysis included 141 participants (40 males and 101 females; mean age, 73.5 ± 6.3 years; follow-up rate: 79.7%). The results of the SEM revealed that oral status (number of teeth present and swallowing function) was positively associated with nutritional status 2 years later. In addition, age was negatively associated with oral status.
CONCLUSION: In community-dwelling older adult dental patients (age ≥60 years), oral function at baseline was associated with nutritional status two years later.
