“…As an example of using equation (39) to map from age distributions to the prevalence of some condition, consider kin suffering from dementia. Figure 3 shows the age-specific prevalence of dementia in Japanese females in 2015 (Fukawa 2018): a roughly exponential increase starting at age 60. In the absence of information on the prevalence pattern in 1947, I will use this prevalence schedule for both years.…”

BACKGROUND Any individual is surrounded by a network of kin that develops over her lifetime. In a justly famous paper, Goodman, Keyfitz, and Pullum (1974) presented formal calculations of the mean numbers of (female, matrilineal) kin implied by a mortality and fertility schedule. OBJECTIVE The aim of this paper is a new theory of kinship demography that provides age distributions as well as expected numbers, permits calculation of properties (e.g., dependency) of kin, is easily computable, and does not require simulation. METHODS The analysis relies on a novel application of the matrix formulation of cohort component population projection to describe the dynamics of a kinship network. The approach arises from the observation that the kin of a focal individual form a population, and can be modelled as one. RESULTS Kinship dynamics are described by a coupled system of non-autonomous matrix equations. I show how to calculate age distributions, total numbers, prevalence, dependency, and the experience of the death of relatives. As an example, I compare the kinship networks implied by the period vital rates of Japanese women in 1947 and 2014. Over this interval, fertility declined by 70% while life expectancy increased by 60%. The implications of these changes for kinship structure are profound; a lifetime dominated, under 1947 rates, by the experience of the death of kin has changed to one in which the death of kin is a rare event. On the other hand, the burden of dependent aged kin, including those suffering from dementia, is many-fold larger under 2014 rates.

“…The significant gender bias of the participants may also affect our results since there were a few male participants in this study. It is well known that nearly two-thirds of people with dementia are women (Fukawa, 2018). In fact, in the nursing home where we conducted the experiment, male residents only accounted for about 17% of all residents (22 persons).…”

A Minimal Design of a Human Infant Presence: A Case Study Toward Interactive Doll Therapy for Older Adults With Dementia

et al. 2021

We introduce a minimal design approach to manufacture an infant-like robot for interactive doll therapy that provides emotional interactions for older people with dementia. Our approach stimulates their imaginations and then facilitates positive engagement with the robot by just expressing the most basic elements of humanlike features. Based on this approach, we developed HIRO, a baby-sized robot with an abstract body representation and no facial features. The recorded voice of a real human infant emitted by robots enhances the robot’s human-likeness and facilitates positive interaction between older adults and the robot. Although we did not find any significant difference between HIRO and an infant-like robot with a smiling face, a field study showed that HIRO was accepted by older adults with dementia and facilitated positive interaction by stimulating their imagination. We also discuss the importance of a minimal design approach in elderly care during post–COVID-19 world.

“…The major inclusion criteria are those who turn or turned 65 years old during 2017 or 2018, underwent 'Frail Kenshin' check-up and were not LTC certified at the time of the check-up. The primary endpoint is the occurrence of LTC need, and the secondary endpoints include LTC care levels (1)(2)(3)(4)(5). CFI and EQ-5D questionnaires were carried out at the venue of check-up, concomitant with other frailty checks, and the completed questionnaires were collected and checked by the person in charge.…”

“…4 Japan has the highest dementia prevalence (2.3% of the population) among Organisation for Economic Co-operation and Development (OECD) countries in 2017, and is projected to reach 3.8% by 2037. 5 In spite of the urgent need to reduce the social burden, there are currently no therapeutic strategies to halt or slow the disease process. 6 7 Lessons from prior studies recommend a focus on preclinical dementia and targeting of potential high-risk individuals who might benefit the most.…”

IntroductionThis research project addresses the lack of screening tools for the early detection of high-risk individuals for long-term care, through four individual studies.Study 1 investigates the predictive ability of the ‘Kihon Check List’, study 2 the ‘Cognitive Function instrument’ and EuroQol-5 Dimension (EQ-5D) and study 3 the ‘Cognitive Function instrument’ and EQ-5D as well as the ‘Frail Kenshin’ health check-up, for incident long-term care certification over a follow-up period of up to 4 years. This is the first large prospective study to evaluate the predictive ability of these tools for the outcome measure long-term care certification. The last subsection of this project study four aims to explore a mixed methods intervention for delaying the need for long-term care. This section is purely exploratory, looking for clues for further studies.Methods and analysisBaseline data have been collected through local government programs, as well as through postal self-reported questionnaires. The primary outcome variable for all studies is long-term care certification data. Statistical analysis will be carried out using Kaplan-Meier, Multiple Cox regression as well as logistic regression.ConclusionThis project hopes to identify tools effective in predicting long-term care need. This will enable identification of citizens that are of higher risk for long-term care in the near future. This subset of high-risk individuals can in the future be addressed for extra support/intervention.Ethics and disseminationAll studies have been approved by respective institutional ethical committees and the WHO ethical committee ERC.0002899. In addition, all studies conform to the provisions of the Declaration of Helsinki and are conducted in accordance with Japan’s ‘Ethical Guidelines for Medical and Health Research Involving Human Subjects’. All findings will be disseminated at conferences and published in peer-reviewed journals.Trial registration numberUMIN000023283.
