27 Year 2022 Global Journal of Medical Research Volume XXII Issue II Version I ( D ) L © 2022 Global Journals Comparison of Taste and Smell Test Results Before and After COVID-19 in Yakumo Residents Health Checkup Comparison between 2019 and 2022 Table 16 shows the results of comparing females' salt taste tests by age group. Comparing the results of the salt taste cognition test in 2022 and 2019, other were no statistically significant difference in each age group. Table 17 shows the results of comparing males' salt taste tests by age group. Comparing the results of the salt taste cognition test in 2022 and 2019, other were no statistically significant difference in each age group. 2019 2022 2019 2022 2019 2022 F-test unpaired-t test Mann-Whitney　test 2019 2022 2019 2022 2019 2022 F-test unpaired-t test Mann-Whitney　test P=0.187 P=0.093 P=0.482 P=0.060 P=0.003** p=0.001* 70s 80s Total P=0.087 P=0.501 P=0.985 P=0.305 P=0.001** P=0.144 40s 50s 60s Table 16　Salty taste test results Comparison Results for 2019 and 2022 Participants　Female（169 in 2019, 202 in 2022） 2019 2022 2019 2022 2019 2022 F-test unpaired-t test Mann-Whitney　test 2019 2022 2019 2022 2019 2022 F-test unpaired-t test Mann-Whitney　test P=0.585 P=0.551 P=0.597 P=0.005* P=0.265 P=0.255 70s 80s Total P=0.365 P=0.807 P=0.962 P=0.019* P=0.342 P=0.261 40s 50s 60s Table 17　Salty taste test results Comparison Results for 2019 and 2022 Participants　Male（129 in 2019, 142 in 2022） IV. D iscussion For both male and female participants, age, height, and weight were not statistically significantly differences for comparison between 2019 and 2022. Females had no statistically significant difference in blood pressure between 2019 and 2022. However, there was no significant difference in diastolic blood pressure among males by age group, but when compared overall, the year 2022 was lower than in 2019. There was no statistically significant difference in cognition between 2019 and 2022 for salty taste. Regarding the sense of smell, there will be a statistically significant (P<0.05) decline in cognition in 2022 compared to 2019. Whether this is due to the COVID-19 epidemic cannot be determined based on the results of this test alone. However, the results of this olfactory cognition test showed that the olfactory cognition in 2022 was lower than the olfactory cognition in 2019. Therefore, we believe that it is necessary to continue to investigate the participants' sense of smell. At that time, we think it is needed to investigate COVID- 19 morbidity as well. We believe it is necessary to track individuals individually. Previous studies have reported a positive correlation between salt intake and blood pressure 15-19) . Therefore, in Japan and overseas, guidance to reduce salt intake is being carried out. Future studies will investigate the relationship dietary habits and blood pressure. It is necessary to investigate this in more detail. Relations with aging 20) and Alzheimer’s disease 21,22) have also been reported regarding the decline in olfactory cognition. We could like to continue research on regional differences in Japan and clarify the results. V. C onclusion We compared taste and smelled simple test results before COVID-19 (2019) and after COVID-19 (2022). As a result, no statistically significant difference was observed in preference in all ages between 2019 and 2022. However, 2022 tended to have fewerol factory perceptions in all ages than in 2019.Butthe smell was a statistically significant difference between 2019 and 2019 in the total participants. Compared to 2022, the value tends to be lower in 2022, with a significant difference overall, and 2022 is not recognizable. It was found that the number of certain odors decreased in 2022. However, on this data, it cannot be concluded that the decline in olfactory recognition in 2022 was due to COVID-19.
