| Outline of Final Research Achievements |
The purpose of this study is to investigate the association of blood pressure (BP) level with physical frailty status and cognitive function among 70, 80 and 90 years old community dwelling Japanese. Community-dwelling older people aged 70±1 (n=1000), 80±1 (n=978) and 90±1 (n=272) years participated in the invitation survey, SONIC study. BP, grip strength, 8-feet gait speed and cognitive function (MOCA-J) were examined on site. The physical frailty was assessed by the CHS criteria. Trend-analysis showed that subjects with higher SBP had lower MOCA-J score in age 70 years and subjects with lower SBP had lower MOCA-J score in age 90 years. These significant trends were seen only in the participants with antihypertensive treatment. Frailty status modified these trends. According to these results, BP target values should be set up by considering age differences. The causal relationship should be clarified whether the cognitive decline is caused by excessive reduction of BP.
