Development of a predictive model for long-term care and support eligibility certification associated with dementia-related functional impairments
The Long-Term Care Insurance (LTCI) system in Japan provides a framework for assessing dementia-related functional decline, enabling the development of predictive models based on daily functional independence. This study aimed to develop and validate risk prediction models for dementia-related functional impairments using data from the Integrated Research Initiative for Living Well with Dementia Cohort Study (IRIDE-CS), integrating multiple cohor…
Age- and sex-specific associations between sarcopenia severity and poor cognitive function among community-dwelling older adults in Japan
Introduction This study examined whether the association between sarcopenia severity and cognitive function differed according to sex and age in community-dwelling older adults in Japan. Methods This is a cross-sectional study of older adults (age ≥ 65 years) consisting of five regional cohorts integrated as the Integrated Research Initiative for Living Well with Dementia (IRIDE) Cohort Study. Sarcopenia severity was determined based on the Asian…
Early- to late-life environmental factors and late-life global cognition in septuagenarian and octogenarians
This study aimed to evaluate cognitively stimulating environments throughout life and to examine direct and indirect associations between these environments and late-life cognition. Early-life education, three domains of work complexity (data, people, and things) based on the longest-held occupation, and engagement in late-life leisure activities (LAs) were assessed. A structural equation model was developed using cross-sectional data of 1721 Jap…
Factors Affecting Care-Level Deterioration among Older Adults with Mild and Moderate Disabilities in Japan
This study aims to investigate the factors of care-level deterioration in older adults with mild and moderate disabilities using nationally standardized survey data for care-needs certification. We enrolled people aged 68 years or older, certified as support levels 1-2 (mild disability) or care levels 1-2 (moderate disability) with no cancer. The outcome was care-level deterioration after two years. The possible factors were physical and mental f…
Construct Validity of a New Health Assessment Questionnaire for the National Screening Program of Older Adults in Japan
The Japanese government has implemented a new screening program to promote measures to avoid worsening lifestyle-related diseases and frailty among the older population. In this effort, the government formulated a new health assessment questionnaire for the screening program of old-old adults aged ≥75 years. The questionnaire comprises 15 items, of which 12 address frailty, two address general health status, and one addresses smoking habits. This…
Prevalence of type 2 diabetes by age, sex and geographical area among two million public assistance recipients in Japan
BACKGROUND: Recognising the importance of the social determinants of health, the Japanese government introduced a health management support programme targeted at type 2 diabetes (T2D) for public assistance recipients (PAR) in 2018. However, evidence of the T2D prevalence among PAR is lacking. We aimed to estimate T2D prevalence by age and sex among PAR, compared with the prevalence among health insurance enrollees (HIE). Additionally, regional di…
Oral Functions Are Associated with Muscle Strength and Physical Performance in Old-Old Japanese
Grip strength and walking speed are considered to be important indicators of physical frailty. However, no study has contemporaneously examined any association of multiple oral functions with grip strength and walking speed. The purpose of this study was to examine which oral functions are associated with muscle strength (grip strength), physical performance (walking speed) or both. The study participants were 511 community-dwelling people (254 m…
Relative validity of brief-type self-administered diet history questionnaire among very old Japanese aged 80 years or older
Objective Dietary questionnaires for assessing dietary intakes among populations of individuals aged 80 years or older (the very old) are very limited. We examined the relative validity of forty-three nutrients and twenty-seven food groups estimated by a brief-type self-administered diet history questionnaire (BDHQ) targeting very old Japanese, using semi-weighed dietary records (DR) as a reference. Design Between June and August 2012 and between…
Impact of a national medical fee schedule revision on the cessation of physician home visits among older patients in Tokyo
As Japan's population continues to age rapidly, the national government has implemented several measures to improve the efficiency of healthcare services and to control rising medical expenses for older patients. One such measure was the revision of the medical fee schedule for physician home visits in April 2014, in which eligibility for these visits was restricted to patients who are unable to visit outpatient clinics without assistance. Throug…
TEACCH-based group social skills training for children with high-functioning autism
BACKGROUND: Although social skills training programs for people with high-functioning autism (HFA) are widely practiced, the standardization of curricula, the examination of clinical effectiveness, and the evaluation of the feasibility of future trials have yet to be done in Asian countries. To compensate for this problem, a Japanese pilot randomized controlled trial (RCT) of the Treatment and Education of Autistic and Related Communication Handi…
P2-308 The characteristics of people who had been screened to be hyperglycaemic but did not visit clinics
Introduction Diabetes poses a significant threat to quality of life due to serious complications including cardiovascular diseases, and as such, many discussions have focused on screening for diabetes. In Japan, the special health examination (“Tokutei Kenshin”) launched in 2008 for all people aged 40–74 includes screening for diabetes. However, some individuals do not make follow-up visits to see a doctor even if they are deemed to be hyperglyca…
