This cohort study aimed to assess weight loss associated with new long-term care insurance (LTCI) certifications over a 9-year period, accounting for the competing risk of death.

Sarcopenia, which is among the most important geriatric syndromes, is also a public health challenge. This study evaluated the performance of the SARC-F, its modified versions and the Quality of Life in Sarcopenia (SarQoL) in screening for sarcopenia.

To estimate the prevalence of nocturia in middle-aged and elderly men and evaluate its associated factors and changes over time.

Recent studies supported the presence of a relationship between pain and frailty, but more research is needed to highlight the pain-frailty association. The study aimed to investigate the prevalence and the influence of different pain indicators on frailty while controlling for age, sex and country.

As aging populations shift health care from hospitals to communities, Japan has implemented policies to promote home health care. This study explored regional differences in home health care recipients among older adults and related factors.

Aphasia is frequently observed in Alzheimer's disease, with its prevalence increasing as the disease progresses. This study highlights the importance of recognizing early language impairments in Alzheimer's disease, and suggests that comprehensive language assessments are crucial for early diagnosis and effective communication interventions.

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.

The number of working older adults has been increasing in the past decade. Past studies have shown that working has a beneficiary effect on the health of older adults. One of the functions that older adults want to maintain is cognitive function, as this function is essential for an independent and high quality of life. Meanwhile, the association between employment >60 years and cognitive function has not yet been organized. In this study, a systematic review was conducted to clarify the longitudinal association between working older adults and cognitive function. A computerized search was performed using PubMed, CINHAL, and PsycINFO for prospective studies published until July 2023. Of the 76 174 studies identified, six were included in the systematic review based on the inclusion and exclusion criteria. Four studies were from Asian countries (one from Taiwan and three from Japan), and two from the USA. Of the six studies, five reported an association between employment later in life and a lower risk of cognitive decline. Three studies examined the association by performing gender-specific analyses, reporting varied results. Overall, the results of this review suggest that the employment of older adults was positively associated with cognitive function over time. Geriatr Gerontol Int 2024; ••: ••-••.

High variations in serially measured blood pressures (BPs) portend a variety of adverse clinical events including dementia, cardiovascular sequelae and frailty. In this study, systolic blood pressure variability (BPV) was examined for its association with fall frequency and time to next fall among older adults living in nursing homes.

The rise in the elderly population all over the world has led to an increase in the health care needs of elderly individuals. Thus, health care professionals need programs to help them develop positive attitudes toward the elderly during their education process. This study aims to explore the effect of interventions that encourage health care students to develop positive attitudes toward the elderly.

In older adults, pressure injuries (PIs) are common and, despite advancements in PI care, are associated with increased complications in patients with dementia for whom standardized treatments are unavailable. Herein, we aimed to examine the influence of dementia status on the care practice pattern and healing outcomes for PI on discharge.

Research on sleep duration and obesity is extensive in children and young individuals but limited and inconsistent for older adults. Our study aims to clarify the current status of this association in the elderly population.

Preventing functional disability benefits the quality of life of older adults and mitigates the economic burden of an aging society. However, the most effective physical performance tests and optimal cut points for identifying older adults at risk of functional disability remain unclear, and Japan lacks physical function-based assessment tools. We aimed to identify the physical performance tests related to functional disability and to develop a predictive test battery for it.

Frailty in older adults is influenced by various factors, such as poor nutritional status. Mid-upper arm circumference (MUAC) is a validated, simple, and non-invasive tool for assessing nutritional status. Despite its potential, no study has explored the association between MUAC and physical frailty in older adults. This study aims to investigate this association and assess whether MUAC can be used as a screening tool in community and primary clinical practice.
