Influence of exercise and dietary habits on the association of alpha-actinin-3 gene polymorphisms with physical function and body composition in community-dwelling individuals aged 60 years and older.

Aim: Alpha-actinin 3 (ACTN3) is associated with diminished physical function and muscle mass in older individuals. However, the effects of lifestyle on this relationship remain unclear. This study explored whether the association between ACTN3 polymorphisms and physical function and body composition varied based on exercise and dietary habits.

[The difference in effect between individual exercise and collective exercise in older adults with frailty-A randomized controlled trial].

Aim: To examine the influence of exercises, including individual and collective exercises, on older adults with frail and prefrail.

Methods: We enrolled 21 older adults with pre-frail and frail (77.1±3.

A Three-Year Longitudinal Follow-Up Study: Does Mild Cognitive Impairment Accelerate Age-Related Changes in Physical Function and Body Composition?

Age-related declines in physical function, body composition, and cognitive function are interrelated. This prospective study aimed to examine the impact of mild cognitive impairment (MCI) on age-related changes in physical function and body composition among community-dwelling older adults. We analyzed data from 180 older adults (aged ≥70 years) who completed a longitudinal assessment of physical function and body composition in the community.

Importance of Lifestyle Activities for Older Adults' Psychosomatic Functions After Driving Cessation: Interpretation by a Mixed-Methods Study.

Older adults who cease driving are more likely to experience psychosomatic decline than those who continue driving. This mixed-methods study was intended to examine differences in psychosomatic functions depending on driving status and lifestyle activities, and factors affecting engagement in additional lifestyle activities after driving cessation. The quantitative analysis included individuals aged 60 and above.

Averting older adults' memory function decline via meaningful activities: a follow-up longitudinal study.

Purpose: The purpose of the study was to investigate the effects of satisfaction with meaningful activities and their performance on the memory function among community-dwelling older adults 3 years later.

Methods: A longitudinal analysis was conducted on 288 community-dwelling older adults aged 65 years and more who had completed the survey in 2019 and 2022 as participants in the Tarumizu Study. Meaningful activities were assessed in 2019 using the Aid for Decision-Making in Occupation Choice for activities.

Association of combined low physical activity and low dietary diversity with mild cognitive impairment among community-dwelling Japanese older adults.

Objective: This study aimed to investigate the potential association between the combination of low physical activity and low dietary diversity with mild cognitive impairment (MCI) in older Japanese adults.

Methods: Data from 600 older adults (mean age 74.1 ± 6.

Associations between driving status, frequency of transport use after driving cessation, and social frailty among middle-aged and older people aged 60 years and older.

Background: The use of transport other than cars is a modifiable factor in the association between driving cessation and social frailty. Clarifying this relationship may serve as a new preventive measure against social frailty among current non-drivers. This study examined the potential association of driving status and transport use with social frailty, as well as between the frequency of transport use and social frailty, among current non-drivers.

Are Middle-Aged and Older Adult Users of Physical Activity Monitoring Systems More Physically Active and at a Lower Risk of Locomotive Syndrome? A Cross-Sectional Web-Based Online Survey.

Background: Physical inactivity is a risk factor for locomotive syndromes and functional limitations in middle-aged and older adults. Therefore, strategies to promote physical activity should be considered. This study investigated whether users of physical activity monitors were more physically active and exhibited a lower risk of locomotive syndrome, compared with non-users.

Associations between information and communication technology use and frailty in community-dwelling old-old adults: results from the ILSA-J.

Objectives: Frailty is a significant cause of adverse health events including long-term care and hospitalization. Although information and communication technology (ICT) has become an integral part of modern life, it remains unclear whether ICT use is associated with frailty.

Design: A cross-sectional study (Integrated Longitudinal Studies on Aging in Japan, ILSA-J).

Associations of Eating Out and Dietary Diversity with Mild Cognitive Impairment among Community-Dwelling Older Adults.

Background: Dementia is a critical late-life health issue that occurs among members of aging societies. This study examined the relationships between eating out, dietary diversity, and mild cognitive impairment (MCI) among community-dwelling older adults.

Methods: We analyzed data from 597 older adults (median age 73.

Independent Association between Cognitive Frailty and Cardio-Ankle Vascular Index in Community-Dwelling Older Adults.

Introduction: Although arterial stiffness has been suggested to be associated with poor physical function and mild cognitive impairment (MCI), its association with cognitive frailty (CF), a comorbidity of both, is unclear. This study aims to examine the association between CF and arterial stiffness in community-dwelling older adults.

Methods: A cross-sectional analysis of 511 community-dwelling older adults aged 65 years or older (mean age 73.

Associations of the Alpha-Actinin Three Genotype with Bone and Muscle Mass Loss among Middle-Aged and Older Adults.

Bone and muscle mass loss are known to occur simultaneously. The alpha-actinin three (ACTN3) genotype has been shown to potentially affect bone and muscle mass. In this study, we investigated the association between the ACTN3 genotype and bone and muscle mass loss in community-dwelling adults aged ≥ 60 years.

Association of self-rated health with type and frequency of social interaction during the declaration of COVID-19 state of emergency among Japanese community-dwelling oldest-old adults.

Aim: To investigate whether the type and frequency of social interaction during the state of emergency due to coronavirus disease were associated with self-rated health (SRH) after the state of emergency.

Methods: Data from a cross-sectional study were collected for 889 oldest-old adults in Bibai City, Hokkaido, Japan. In total, 612 participants (mean age: 83.

Association of Sleep Quality Status With Worsening Low Back or Knee Pain During The COVID-19 State of Emergency Among Old-Old Adults.

Background: Poor sleep quality has a negative effect on pain among older adults. During the coronavirus disease 2019 (COVID-19) state of emergency, lifestyle changes can cause psychologic stressors and lead to poor sleep quality.

Aim: This study examined whether sleep quality status was associated with low back or knee pain changes during the COVID-19 state of emergency among community-dwelling Japanese old-old adults.
