  • Association Between Plasma Pentosidine and Skeletal Muscle‐Related Indices in Older Adults Without Diabetes

    Open Access•Takashi Shida, Sho Hatanaka et al.•ARTICLE•Geriatrics and gerontology…•2026

  • Sex-specific factors associated with acceptance of smartwatches among urban older adults

    Open Access•Naoki Deguchi, Yosuke Osuka et al.•ARTICLE•Frontiers in Public Health•2024

    Smartwatches (SW) are wearable devices that support daily life and monitor an individual’s health and activity status. This information is utilized to promote behavior modification, which could help prevent chronic diseases and manage the health of older adults. Despite being interested in SWs, older adults tend to decrease their SW usage as they age. Therefore, understanding the acceptance of SWs among older individuals can facilitate individual…

  • Association between Dementia Severity and Oral Hygiene Management Issues in Older Adults with Alzheimer’s Disease

    Open Access•Maki Shirobe, Ayako Edahiro et al.•ARTICLE•International Journal of…•2023

    Oral hygiene management issues vary across types and clinical stages of dementia. We aimed to clarify the issues related to oral hygiene management in older adults with Alzheimer's disease (AD) according to stages defined by the Functional Assessment Staging of Alzheimer's Disease (FAST). In all, 397 records (45 men and 352 women; average age, 86.8 years; age range, 65-106) from older adults with AD were used for the cross-sectional study. We use…

  • The Relationship Between Cognitive Decline and All-Cause Mortality Is Modified by Living Alone and a Small Social Network

    Open Access•Hikari Murayama, Mika Sugiyama et al.•ARTICLE•The Journals of Gerontology…•2023

    Although living alone and having a small social network represent an isolated status, their modifying effects were the opposite. These findings indicate that the isolation type should be considered when implementing support strategies for older adults with cognitive decline or dementia

  • Standard Values and Concurrent Validity of a Newly Developed Occlusal Force-Measuring Device among Community-Dwelling Older Adults

    Open Access•Masanori Iwasaki, Ichinosuke Maeda et al.•ARTICLE•International Journal of…•2022

    Recently, an occlusal force-measuring device with a capacitive-type pressure-mapping sensor (OFMD-CPS) was developed. We aimed to establish age- and sex-specific standard values for OFMD-CPS-measured occlusal force (OF) and to assess the concurrent validity of the OFMD against another OF measuring system with a pressure-sensitive sheet (Dental Prescale II). Using data from a population-based study, we calculated the OFMD-CPS-measured OF means and…

  • Factors Predicting Tongue Pressure Decline among Community-Dwelling Older Adults

    Open Access•Chika Takahashi, Masanori Iwasaki et al.•ARTICLE•International Journal of…•2022

    A limited number of longitudinal studies have explored factors contributing to decreases in tongue pressure (TP). This longitudinal study aimed to clarify the factors affecting TP decline among community-dwelling older adults. We followed the Takashimadaira Study participants with a baseline TP ≥ 30 kPa for 2 years. A TP of <30 kPa at follow-up was defined as TP decline. We used Poisson regression with robust standard errors to explore the factor…

  • Relationship between Oral Hypofunction and Sarcopenia in Community-Dwelling Older Adults

    Open Access•Yoshihiro Kugimiya, Masanori Iwasaki et al.•ARTICLE•International Journal of…•2021

    Oral hypofunction, resulting from a combined decrease in multiple oral functions, may affect systemic-condition deterioration; however, few studies have examined the association between oral hypofunction and general health among older adults. In this cross-sectional study, we examined the relationship between oral hypofunction and sarcopenia in community-dwelling older adults. We included 878 adults (268 men and 610 women, mean age 76.5 ± 8.3 yea…

  • Relationship between Chewing Ability and Nutritional Status in Japanese Older Adults

    Open Access•Keiko Motokawa, Yurie Mikami et al.•ARTICLE•International Journal of…•2021

    We concluded that chewing ability was closely associated with nutrient and different food groups' intake, as well as undernutrition, among Japanese community-dwelling elders. Thus, to ensure comprehensive nutritional management, nutritionists and dentists should collaborate when treating the same patients

  • Relationship between Mortality and Oral Function of Older People Requiring Long-Term Care in Rural Areas of Japan

    Open Access•Shiho Morishita, Yuki Ohara et al.•ARTICLE•International Journal of…•2021

    Oral ingestion influences the life sustenance, quality of life, and dignity of older adults. Thus, it is an important issue in medical care and the welfare of older adults. The purpose of this four-year prospective cohort study was to investigate the relationship between mortality and oral function among older adults who required long-term care and were living in different settings in a rural area of Japan. This study included 289 participants ag…

  • A Two-Year Longitudinal Study of the Association between Oral Frailty and Deteriorating Nutritional Status among Community-Dwelling Older Adults

    Open Access•Masanori Iwasaki, Keiko Motokawa et al.•ARTICLE•International Journal of…•2020

    Community-dwelling older adults with oral frailty had an increased risk of deteriorating nutritional status
