Linear Association between Frailty as Assessed by the Kihon Checklist and Quality of Life in Community-Dwelling Older Adults: A Cross-Sectional Population-Based Study.

Background: The need for support focused on frailty and quality of life (QoL) in older adults is increasing. The Kihon Checklist (KCL) is a comprehensive and easy-to-use tool to assess frailty in older adults. Previous studies have shown associations between frailty and QoL; however, few studies have investigated the association between frailty using the KCL and QoL.

Association Between Occupational Participation and Quality of Life in Japanese Older Adults.

Positive associations between occupational participation and quality of life (QoL) are known in various populations, but there are few reports in older adults in Japan. To quantify the association between occupational participation in meaningful occupations and QoL among Japanese community-dwelling older adults. A self-administered questionnaire was sent to 626 older adults.

Association Between the Use of Information and Communication Technology Tools and Each Domain of Cognitive Function Among Community-Dwelling Older Adults: A Prospective Cohort Study.

Background: This study aimed to determine the association between the use of information and communication technology (ICT) tools, such as mobile voice calling, e-mail, and video calling, and cognitive function among community-dwelling older adults.

Methods: For the 220 included participants aged ≥65 years, baseline surveys conducted from 2017 to 2018 assessed demographics. Additionally, cognitive function domains were evaluated using the Word List Memory Task, Trail Making Test, and Symbol Digit Substitution Task on a tablet PC.

Association between Productive Roles and Frailty Factors among Community-Dwelling Older Adults: A Cross-Sectional Analysis.

The employment rate of older people in Japan is expected to increase in the future owing to the increase in the retirement age. Preventing frailty is imperative to maintaining productive roles of older adults. Therefore, this study aimed to examine the association between productive roles and frailty factors among community-dwelling older adults.

Associations of fall history and fear of falling with multidimensional cognitive function in independent community-dwelling older adults: findings from ORANGE study.

Background: Falls and fear of falling (FoF) inhibit healthy longevity and have been suggested to be associated with cognitive function. However, the domains of cognitive function that are associated with them remain controversial. It is speculated that clarifying this will help in the assessment of health status and interventions in the community.

Association between Kihon check list score and geriatric depression among older adults from ORANGE registry.

Objective: Older adults in Japan are tackling health-related challenges brought by comprehensive geriatric symptoms, such as physical and cognitive problems and social-psychological issues. In this nationwide study, we mainly focused on the Kihon checklist (KCL) as certificated necessity of long-term care for Japanese older adults and investigated whether the KCL score was associated with geriatric depression. In addition, we aimed to identify critical factors that influence the relationship between the KCL score and geriatric depression.

Perceived declining physical and cognitive fitness during the COVID-19 state of emergency among community-dwelling Japanese old-old adults.

Aim: Perceived health status, including physical and cognitive fitness, will be negatively associated with future health conditions among old-old adults. The coronavirus disease 2019 (COVID-19) pandemic has caused sudden changes in lifestyle. Thus, this study examined the associations of participation in an exercise class before the COVID-19 pandemic and the exercise habits and disruption to the rhythms of daily life during the COVID-19 state of emergency with perceived declining physical and cognitive fitness among community-dwelling old-old adults.
