Care preferences of healthy, middle-aged adults in Japan and the USA if they acquired dementia: A cross-sectional observational study

Aim: Japan introduced dementia-friendly initiatives into its national policies to help people with dementia remain involved in society for as long as possible. However, some people might choose to live in a nursing home to avoid care burden on family members. Understanding middle-aged adults’ preferences for place of care and identifying factors that influence their preferences would help policy decision-makers promote dementia-friendly initiatives. The present study aimed to investigate the care preferences of middle-aged adults if they acquired dementia in Japan and the USA. Methods: We carried out a cross-sectional observational study using an internet-based questionnaire survey of Japanese residents with Japanese ethnicity, Japanese Americans, and non-Asian Americans aged 40–70 years. A total of 301 participants, including 104 Japanese residents, 93 Japanese Americans and 104 non-Asian Americans, completed the survey. Participants were asked to answer the items based on a hypothetical situation in which they had acquired dementia requiring regular care and supervision. Results: Participants preferred nursing home care (29.9%), followed by professional home care (19.6%), family home care (17.6%) and hospital care (11.3%). Japanese residents had a significantly lower preference for professional home care than did Japanese or non-Asian Americans (adjusted odds ratio 0.28, 95% confidence interval 0.10–0.75). Between-ethnicity difference in care preferences was not observed. Conclusions: A low preference for professional home care among the middle-aged adults might be influenced by country-specific long-term and dementia care systems. Policy decision-makers should develop professional home care services that are more available for families of people living with dementia. Geriatr Gerontol Int 2019; 19: 829–833.
