| Outline of Final Research Achievements |
Forty-three elderly individuals residing in nursing homes in Japan were enrolled (n = 43, 82.3 ± 8.5 years), and were compared with an independently living elderly group (n = 949, years), aiming to compare taste detection ability. Information regarding comorbidity and medication were obtained as general health status, and oral status including number of present teeth, denture usage, maximal occlusal force were also noted. In the dependently living group, 69.4%, 14.3%, 16.3% and 8.2% of participants could detect sweet, sour, salty and bitter tastes, respectively, which was significantly lower than the independently living group for each taste (97.9%, 70.8%, 89.6% and 43.8%, respectively). The multivariate logistic regression analysis revealed that residing in nursing homes was associated with reduced sensitivity for four different tastes. It is concluded that the diseases and the situation of dependent elders were more likely the cause of the decreased taste sensitivity.
