Long-term effects of rice-farming care on cognitive function and mental health of elderly people with cognitive impairment: a follow-up study

How are nature-based interventions defined in mild cognitive impairment and dementia studies? A conceptual systematic review and novel taxonomy

OBJECTIVES

To systematically review research testing nature-based interventions for people living with mild cognitive impairment or dementia, and to report how authors have defined their interventions by presenting a taxonomy of the nature-based interventions.

METHODS

A conceptual systematic review of research published between 2008 and 2024 investigating nature-based interventions for people living with mild cognitive impairment or dementia was conducted. Three reviewers contributed independently. Exclusion criteria: not specifying if participants had mild cognitive impairment or dementia, only recruiting caregivers, no primary data, study protocols, abstracts, reviews, not peer-reviewed journal articles and any other grey literature. Intervention descriptions within the papers were thematically analysed.

RESULTS

Fifty-two articles reporting fifty-one studies were included. The most common interventions were nature virtual reality (VR technology) and gardening. From the definition data, we produced a taxonomy with overarching domains of: (a) Other terms used; (b) Characteristics; (c) Activities. Subdomains included: development or approach, modes of action, location, physical features, and activities. Some interventions could be grouped. Structure and standardisation of the interventions varied, with a lack of clear reporting.

CONCLUSION

This taxonomy provides conceptualisations of nature-based interventions that can be used by future researchers to guide the development, evaluation and reporting of robust interventions in this area.

Rice farming care as a novel method of green care farm in East Asian context: an implementation research

Background

Green care farms, which offer care for people with dementia in a farm setting, have been emerging in the Netherlands. The aim of this study was to 1) implement green care farms which use rice farming in Japan, 2) explore the positive experiences of rice farming care, and 3) compare the effect of rice farming care to that of usual care on well-being and cognitive ability.

Methods

We developed a new method of green care farm in Japan which uses rice farming, a farming that is practiced all over East Asia. The participants were 15 people with dementia (mean age = 75.6 ± 9.8 years) who participated in a one-hour rice farming care program once a week for 25 weeks. We also collected qualitative data on the positive experiences of study participants after the program. As a reference data, we also collected the corresponding data of the usual care group which included 14 people with dementia (mean age = 79.9 ± 5.8 years) who were attending the near-by day-care.

Results

The mean participation rate on the rice farming care group was 72.1%. After the intervention, participants reported experiencing enjoyment and connection during the program. It also changed the staff’s view on dementia. The green care farm group showed a significant improvement in well-being but no significant difference in cognitive function compared to the usual care group.

Conclusions

Green care farms by using rice farming is promising care method which is evidence-based, empowerment-oriented, strengths-based, community-based dementia service, which also delivers meaningful experience for the people with dementia in East Asia.

Care Farming for People with Dementia; What Can Healthcare Leaders Learn from This Innovative Care Concept?

There is growing recognition that traditional dementia care models fall short for people with dementia and their family caregivers. This has led to a call for new dementia care approaches. In response to this call, innovations in long-term dementia care are taking place both in the community and in residential care. One of these innovations is the care concept called “care farming.” Care farms are farms that combine agricultural activities with care and support services for a variety of client groups, including people with dementia. Although the concept is being implemented in an increasing number of countries, the Netherlands and Norway are still front-runners in providing and researching this innovative dementia care approach. Over the last couple of years, several research projects have been carried out in these countries addressing a wide range of issues related to dementia care provision at care farms and using a wide range of research methods. This paper synthesizes the knowledge that has been generated in these research projects. By sharing the knowledge obtained in the Netherlands and Norway, we hope to inspire leaders in healthcare undertaking similar efforts to innovate care for the increasing number of people with dementia. By providing starting-points for future research, we additionally hope to contribute to a research agenda to further advance the field.
