The present study examined the relationship between olfactory function and taste function for ten years. A personal function test was calculated from the Yakumo study database, and the odour stick identification test and salt taste identification test were administered to healthy elderly people. The participants were community dwellers who voluntarily participated in the Yakumo Study and had managed everyday life by themselves. We combined data of ten years (2009-2018) and checked a taste test result and the olfactometry result. This data were made from a consultation result list which was handed to a testee by hand. The testee was in his/her 80s from 40s. The data were compared according to the generation. They were classified into three categories: the normal range, observation required, consultation required. The gustatory test was performed using test paper SALSAVE (ADVANTEC Co. Ltd.), which included 7 different densities of NaCl on a test paper, as follows: 0.0, 0.6, 0.8, 1.0, 1.2, 1.4 and 1.6 mg/cm2. The participant placed a test paper on the tongue and closed the mouth to feel the taste. The Odour Stick Identification Test (OSIT-J) was used to assess odour perception. This test possesses high reliability and validity. The OSIT-J includes 12 different odorants to be identified. We compared the answer of generation and found that recognition of odour identification test was that the participant of the normal range decreases with age, on the contrary, participants of the consultation required increase with age. It was revealed that Male participant had worsen olfactometry result by the generation that was earlier than Female participant. Also, it was found that there was difference between age with regard to taste examination results. Based on the taste examination results, there were not huge difference between males and females. It will be necessary to obtain the result of the aging through olfactory and taste examination by performing more detailed data analysis in the future.

Key words: Healthy elderly people, olfactory function, taste function, Yakumo study.
