Denture wearing associated with malnutrition among elderly and requires long-term care
Denture use, lip-closure ability, and activities of daily living were significantly associated with malnutrition in older adults according to a recent study published in the Journal of Dental Sciences
In recent years, Japan and other developed countries have faced a super-ageing society; therefore, extending healthy life expectancy has become an important social issue. Previous reports have revealed oral health status plays an important role in maintaining nutritional status. Dentures are important for the reconstruction of occlusal support and masticatory performance for older adults with poor dentition. We aimed to elucidate the oral health factors associated with malnutrition in older adults requiring long-term care, including denture use.
This cross-sectional study included 322 older adults (63 men, 259 women; mean age, 86.6 ± 6.9 years) who required long-term care in rural Japan. The participant's nutritional status was assessed using the Mini Nutritional Assessment-Short Form (MNA®-SF). Oral health was assessed using the participant's dentition and oral function. Barthel Index (BI) and medical history were measured for assessing general health status. Multiple logistic regression analyses were performed to determine the oral health factors associated with malnutrition.
Results of the study are:
The proportion of participants with malnutrition was 17.2%. The BI score having <20 teeth and dentures and poor lip-closure ability were significantly associated with malnutrition.
Thus, denture use, lip-closure ability, and activities of daily living were significantly associated with malnutrition in older adults requiring long-term care, suggesting that wearing dentures for tooth loss and maintaining oral function contributes to nutritional status.
