Background: Depression in old age is associated with the incidence of dementia. However, whether a combination of somatic and psychological symptoms influences the risk of dementia has not been fully investigated.
Objective: We aimed to determine the association between the combination of psychological and somatic symptoms of depression and the incidence of dementia.
Aim: Sarcopenia's high prevalence in older adults with cardiovascular disease (CVD) suggests that the risk of comorbidity in sarcopenia might also be increased during the at-risk phase of CVD. However, the relationship between CVD risk and sarcopenia has not been elucidated. Therefore, the purpose of this cross-sectional study was to investigate the association between CVD risk and sarcopenia in community-dwelling Japanese older adults.

Method: Participants included 4648 Japanese older adults (mean age 73.8 ± 5.
Purpose: The purpose of the present study was to comprehensively examine the association between inadequate physical activity (PA), cognitive activity (CA), and social activity (SA) and the development of sarcopenia.
Methods: We conducted a two-wave survey. In the first-wave survey, we asked participants five questions for each of the three categories-PA, CA, and SA.
Objective: The present study examined whether dietary diversity is associated with chronic kidney disease (CKD) in community-dwelling older Japanese adults.
Methods: Participants comprised 8,195 older adults (mean age was 74.0 ± 5.
Aims: Vulnerable older adults tend to decrease physical activity (PA) and increase sedentary time (ST). Previous research on the associations between ST and brain volume have yielded inconsistent findings, without considering the impact of cognitive engagement (CE) on cognitive function. We aimed to examine the association between ST with CE and brain volume.

Methods: This cross-sectional study was carried out in a general community setting. MCI and global cognitive impairment (GCI) were assessed using the Mini-Mental State Examination and National Center for Geriatrics and Gerontology-Functional Assessment Tool, which are multicomponent neurocognitive tests that include memory attention, executive function and processing speed.
Background: Sarcopenia is a clinical issue in older adults that leads to serious adverse health outcomes, including disability. The present study investigated whether dietary diversity affects the incidence of disability in older adults with sarcopenia.
Method: Participants were 759 Japanese older adults with sarcopenia (mean age 77.
Objectives: To examine the associations of a combination of urinary incontinence (UI) and life-space activity/mobility with the risk of incident disability among community-dwelling older adults.
Study Design: The participants were 12,808 older adults for the cross-sectional study and 12,516 older adults who completed the follow-up assessment.
Main Outcome Measures: UI was assessed using a questionnaire.
Background: Although overlapping frailty and fear of falling (FoF) are likely to increase with population aging, the combined effect of frailty and FoF on incident disability is not yet well understood.
Aims: The purpose of this study is to examine whether frailty combined with FoF increased the risk of incident disability in older adults. Our secondary purpose was to clarify the synergistic effect of frailty and FoF on incident disability.
Objectives: Self-monitoring of physical, cognitive, and social activities may be a means of helping older adults to adopt or maintain an active lifestyle, but its effect on disability onset is unknown. This study aimed to examine the association between self-monitoring of the activities and disability onset in older adults.
Design: Longitudinal, observational study.
Objectives: The aim of this study was to examine whether dietary diversity is associated with sarcopenia in community-dwelling older Japanese adults.
Methods: We used a cross-sectional large cohort data set from the National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes. Data from 9080 older adults (mean age 74 ± 5.
Background: The motoric cognitive risk syndrome (MCR) was characterized by slow gait and subjective cognitive complaints. MCR was associated with brain structural changes. However, the association between white matter hyperintensities (WMH) and MCR was unclear and the aim of this study was to examine this association.
View Article and Find Full Text PDFBackground: Active mobility index (AMI) is a questionnaire to assess going-out behavior with physical and social activity. The association between AMI scores and objectively measured physical activity (PA) in older adults is unknown.
Methods: Community-dwelling older adults aged ≥ 70 years participated in an examination and wore a triaxial accelerometer for seven or more days.
Objectives: Diabetes mellitus (DM) is associated with risk of sarcopenia. However, whether glycated hemoglobin (HbA1c) levels are associated with sarcopenia has not reached a consensus. The purpose of this study was to examine the association between diabetes status based on HbA1c levels and sarcopenia indices in community-dwelling older adults stratified by body mass index (BMI) status.
View Article and Find Full Text PDFBackground: A physically active lifestyle, including physical and social activities, is needed to maintain muscle mass, strength, and physical performance. A large life space characterizes an active lifestyle, but the association between life space with physical and social activities and sarcopenia is unclear. This study aimed to examine the association between life space with physical and social activities, assessed using the Active Mobility Index (AMI), and sarcopenia in community-dwelling Japanese older adults.

Methods: This is a prospective study in a community setting. Participants were surveyed baseline conditions of social frailty and driving status (n = 4642, mean age: 71.
