Nature-based social interventions to address loneliness among vulnerable populations: a common study protocol for three related randomized controlled trials in Barcelona, Helsinki, and Prague within the RECETAS European project
2024
Background
The negative effects of loneliness on population health and wellbeing requires interventions that transcend the medical system and leverage social, cultural, and public health system resources. Group-based social interventions are a potential method to alleviate loneliness. Moreover, nature, as part of our social and health infrastructure, may be an important part of the solutions that are needed to address loneliness. The RECETAS European project H2020 (Re-imagining Environments for Connection and Engagement: Testing Actions for Social Prescribing in Natural Spaces) is an international research project aiming to develop and test the effectiveness of nature-based social interventions to reduce loneliness and increase health-related quality of life.
Methods
This article describes the three related randomized controlled trials (RCTs) that will be implemented: the RECETAS-BCN Trial in Barcelona (Spain) is targeting people 18+ from low socio-economic urban areas; the RECETAS-PRG Trial in Prague (Czech Republic) is addressing community-dwelling older adults over 60 years of age, and the RECETAS-HLSNK trial is reaching older people in assisted living facilities. Each trial will recruit 316 adults suffering from loneliness at least sometimes and randomize them to nature-based social interventions called “Friends in Nature” or to the control group. “Friends in Nature” uses modifications of the “Circle of Friends” methodology based on group processes of peer support and empowerment but including activities in nature. Participants will be assessed at baseline, at post-intervention (3 months), and at 6- and 12-month follow-up after baseline. Primary outcomes are the health-related quality-of-life according to 15D measure and The De Jong Gierveld 11-item loneliness scale. Secondary outcomes are health and psychosocial variables tailored to the specific target population. Nature exposure will be collected throughout the intervention period. Process evaluation will explore context, implementation, and mechanism of impact. Additionally, health economic evaluations will be performed.
Discussion
The three RECETAS trials will explore the effectiveness of nature-based social interventions among lonely people from various ages, social, economic, and cultural backgrounds. RECETAS meets the growing need of solid evidence for programs addressing loneliness by harnessing the beneficial impact of nature on enhancing wellbeing and social connections.

Loneliness may predict impaired cognition among older people. The aim of this study was to determine the effects of socially stimulating group intervention on cognition among older individuals suffering from loneliness.
A randomized controlled trial.
Two hundred thirty-five participants (≥75 years) in seven day care centers in Finland.
Group intervention was based on the effects of closed-group dynamics and peer support. The three-month intervention was aimed to enhance interaction and friendships between participants and to socially stimulate them. Each group was facilitated by two specifically trained professionals. In addition to active discussions, the groups included three types of activities depending on the participants' interests: 1) therapeutic writing; 2) group exercise; and 3) art experiences.
Cognition was measured by the Alzheimer's Disease Assessment Scale (ADAS–Cog), and mental function was measured by the 15D measure.
The intervention and control groups were similar at baseline with respect to their demographics, disease burden, depression, and cognition. The ADAS–Cog scale improved more in the intervention group than in the control group within the three-month period, with mean changes being −2.6 points (95% confidence interval [CI]: −3.4 to −1.8) and −1.6 points (95% CI: −2.2 to −1.0), respectively. The dimension of mental function in the 15D showed significant improvement at 12 months in the intervention group (+0.048, 95% CI: +0.013 to +0.085) compared with the control group (−0.027, 95% CI: −0.063 to +0.010).
Psychosocial group intervention improved lonely older people's cognition.

Objective: We explored the effectiveness of preventive home visits on the health-related quality-of-life (HRQoL) and mortality among independently community-dwelling older adults.
Design: A randomised controlled trial.
Subjects: Independently home-dwelling older adults 75 years and older, consisting of 211 in the intervention and 211 in the control group.
Setting: Hyvinkää town municipality, Finland.
Main outcome measures: We used the change in HRQoL measured by the 15D scale as our primary outcome. Mortality at two years was retrieved from central registers.
Results: At the one-year time point, the HRQoL according to the 15D scores deteriorated in the control group, whereas we found no change in the intervention group. The difference between the 15D score changes between the groups was −0.015 (95% CI −0.029 to −0.0016; p = 0.028, adjusted for age, sex, and baseline value). At the two-year time point as the visits ended, that difference diminished. There was no difference in mortality between the groups during the 24-month follow-up.
Conclusion: Preventive home visits implemented by a multidisciplinary team with CGA appear to help slow down the decline in HRQoL among older adults, although the effect diminishes when the visits end.
Key points
We are exploring preventive home visits as means to support the health-related quality-of-life (HRQoL) of home-dwelling older adults
Multiprofessional preventive home visits in this intervention study helped to maintain the HRQoL when measured using 15D
The effects on HRQoL diminished when the intervention ended, so could further benefits be attained with a longer intervention?The clinical trial registration number: ACTRN12616001411437

Background
Loneliness is common among older adults in institutional settings. It leads to adverse effects on health and wellbeing, for which nature contact with peers in turn may have positive impact. However, the effects of nature engagement among older adults have not been studied in randomised controlled trials (RCT). The “Friends in Nature” (FIN) group intervention RCT for lonely older adults in Helsinki assisted living facilities (ALFs) aims to explore the effects of peer-related nature experiences on loneliness and health-related quality of life (HRQoL). In this study we aim describe the participants’ baseline characteristics of the RCT, feasibility of FIN intervention and intervention participants’ feedback on the FIN.
Methods
Lonely participants were recruited from 22 ALFs in Helsinki area, Finland, and randomised into two groups: 1) nature-based social intervention once a week for nine weeks (
n
= 162) and 2) usual care (
n
= 157). Demographics, diagnoses and medication use were retrieved from medical records, and baseline cognition, functioning, HRQoL, loneliness and psychological wellbeing were assessed. Primary trial outcomes will be participants’ loneliness (De Jong Giervald Loneliness Scale) and HRQoL (15D).
Results
The mean age of participants was 83 years, 73% were female and mean Minimental State Examination of 21 points. The participants were living with multiple co-morbidities and/or disabilities. The intervention and control groups were comparable at baseline. The adherence with intervention was moderate, with a mean attendance of 6.8 out of the nine sessions. Of the participants, 14% refused, fell ill or were deceased, and therefore, participated three sessions or less. General subjective alleviation of loneliness was achieved in 57% of the intervention participants. Of the respondents, 96% would have recommended a respective group intervention to other older adults. Intervention participants appreciated their nature excursions and experiences.
Conclusions
We have successfully randomised 319 lonely residents in assisted living facilities into a trial about the effects of nature experiences in a group-format. The feedback from participants was favourable. The trial will provide important information about possibilities of alleviating loneliness with peer-related nature-based experiences in frail residents.

BackgroundBioimpedance skeletal muscle indices (SMI) are used as a surrogate for skeletal muscle mass, but their associations with physical functioning and obesity need further evaluation.AimsTo compare the associations of body mass index (BMI), bioimpedance spectroscopy-based calf intracellular resistance (Cri-SMI), and single-frequency bioimpedance analysis (SF-SMI) indices with physical performance and the functioning of community-dwelling older people at risk of or already suffering from sarcopenia.MethodsPre-intervention measurements of the screened subjects and the participants of the Porvoo sarcopenia trial (N = 428) were taken. Cri-SMI, whole-body SF-SMI, and BMI were related to hand-grip strength, walking speed, short physical performance battery (SPPB), and the physical component of the RAND-36.ResultsAmong the older people (aged 75–96), Cri-SMI correlated inversely with age (men r = - 0.113, p < 0.001; women r = - 0.287, p < 0.001), but positively with SPPB (r = 0.241, p < 0.001) and the physical component of the RAND-36 (r = 0.114, p = 0.024), whereas BMI was inversely associated with SPPB (r = - 0.133, p < 0.001) and RAND-36 (r = - 0.286, p < 0.001). After controlling for age, gender, and comorbidity, one unit of Cri-SMI (cm2/Ω) was associated with a 3.3-fold probability of good physical performance (SPPB ≥ 9 points, OR = 3.28, p < 0.001) and one unit of BMI (kg/m2) decreased the respective probability 4% (OR= 0.96, p = 0.065). Physical inactivity partly explained the negative association of BMI. When Cri-SMI and BMI were controlled for, a 1% difference in Cri-SMI was associated with a 0.7% (p < 0.001) higher probability of good performance, the respective figure being - 2.2% (p = 0.004) for BMI. The associations of SF-SMI with physical functioning indices were insignificant.ConclusionsIndependent of each other, Cri-SMI was positively and BMI was inversely associated with the physical performance and functioning of community-dwelling older people who were at risk of or already suffering from sarcopenia. We found no association between SF-SMI and physical functioning.

Evaluating the feasibility of “Friends in Nature,” a complex nature-based social intervention to address loneliness and quality of life in six cities worldwide
2024
Background
Loneliness, a major public health concern, could be alleviated through social interventions with nature contact as a primary component. “Friends in Nature” is a complex nature-based social intervention designed to be implemented as part of “Reimagining Environments for Connection and Engagement: Testing Actions for Social Prescribing in Natural Spaces\" (RECETAS). This project aims to alleviate loneliness and promote health-related quality of life in six different geographic areas worldwide. Feasibility studies are crucial to assess the viability of complex interventions and study procedures before conducting definitive studies. This paper aims to describe the design, implementation, and evaluation of the six-related feasibility studies on the “Friends in Nature” intervention. These studies specifically evaluate feasibility of recruitment and study procedures, intervention implementation, and data collection and distribution.
Methods
We defined a comprehensive set of indicators to assess the feasibility of “Friends in Nature.” For the first domain, recruitment procedures were assessed to determine their adequacy, while attrition rates were examined to assess participant retention. For the second domain, the implementation of interventions was evaluated, along with the study design’s ability to adapt to unexpected situations and participant adherence to the intervention. Finally, for the third domain, completion rates and the acceptability of the study activities were also analyzed. The feasibility of using specific scales to assess loneliness and well-being was also explored.
Results
The feasibility indicators defined for this study were useful to assess the feasibility of “Friends in Nature.” Recruitment procedures were generally found to be adequate, and the number of dropouts was low. Interventions were implemented with minor adjustments, and facilitators played a vital role in the well-functioning of the interventions. Although some unexpected situations occurred during the study, adaptations were made, and participants were generally satisfied with the activities proposed. Scales used to assess loneliness and quality of life showed potential for measuring the effects of nature-based social prescribing in the full trial.
Conclusion
This paper offers valuable insights into the design and execution of feasibility studies for complex interventions like “Friends in Nature.” Findings from these assessments explore the feasibility of “Friends in Nature” and will inform the main RECETAS studies, which are designed to strengthen the evidence base to support the use of nature-based social prescribing to reduce loneliness and promote quality of life.

Loneliness has proved to be common in long-term care facilities (LTCF) and is associated with adverse health outcomes. Although older residents have expressed their experiences of loneliness in previous studies in various ways, researchers have rarely distinguished or explored the three dimensions of loneliness: social, emotional and existential. Furthermore, descriptions of existential loneliness in LTCF is still a neglected area of research. The aim of this study was to explore how the experiences of loneliness of older people in LTCF are manifested and divided into these dimensions. We used an ethnographic multi-method approach. The analysis leaned on abductive reasoning. In terms of social loneliness, the respondents missed company and lacked peer support, but also felt lonely in a crowd. Emotional loneliness felt miserable and could not be shared with anyone. It was related to a feeling of meaninglessness of life and a lack of meaningful others. Existential loneliness was characterised by waiting and a feeling of emptiness. It reflected the fundamental issues of humanity. The present study is one of the first to explore the dimensions of the experiences of loneliness among frail and cognitively impaired older people in LTCF. According to the voices of the lonely respondents, loneliness has many social, emotional and existential aspects. These features of loneliness should be recognised in studies, care practices and interventions.

Effect of Physical Exercise on Cognitive Performance in Older Adults with Mild Cognitive Impairment or Dementia: A Systematic Review
2014
Numerous studies have shown that physical exercise has positive effects on cognition in healthy adults. Less is known about the effectiveness of exercise interventions in older individuals already suffering from mild cognitive impairment (MCI) or dementia. The aim of this study was to systematically review the evidence from randomized controlled trials (RCTs) of the effects of physical exercise on cognition in older subjects with MCI or dementia. PubMed, Cochrane and DARE databases were systematically searched for RCTs using terms related to cognition and physical exercise. Altogether, 22 trials were found. The studies on older subjects with MCI reported some positive effects of physical exercise on cognition, mainly on global cognition, executive function, attention and delayed recall. However, most studies performed on older subjects with dementia showed no effect of exercise on cognition. The studies had methodological problems in defining dementia/MCI diagnosis, blinding, inadequate sample sizes and not reporting dropouts, compliance or complications. More studies of good quality on older adults with dementia are needed.

Background
Polypharmacy and inappropriate drug use is associated with negative health outcomes among older people. Various interventions for improving drug treatment have been evaluated, but the majority of studies are limited by the use of surrogate outcomes or suboptimal design. Thus, the potential for clinically significant improvements from different interventions is still unclear. The main objective of this study is therefore to evaluate the effect upon patient-relevant endpoints of a cooperation between geriatricians and general practitioners on complex drug regimens in home-dwelling elderly people.
Methods
This is a cluster randomised, single-blind, controlled trial where general practitioners are invited to participate with patients from their lists. The patients must be 70 years or older, use at least seven different medications and have their medications administered by the home nursing service. We plan to recruit 200 patients, with randomisation at physician level. The intervention consists of three main parts: (1) clinical geriatric assessment of the patient, combined with a thorough review of their medications; (2) a meeting between the geriatrician and general practitioner, where the two physicians combine their competence and knowledge and discuss the drug list systematically; (3) clinical follow-up, depending on the medication changes that have been done. The study period is 24 weeks, and the patients are assessed at baseline, 16 and 24 weeks. The primary outcome measure is health-related quality of life according to the 15D instrument. Secondary outcome measures include physical and cognitive functioning, medication appropriateness, falls, carer burden, use of health services (hospital or nursing home admissions, use of home nursing services) and mortality.
Discussion
Our choice of patient-relevant outcome measures will hopefully provide new knowledge on the potential for clinical improvements after performing comprehensive medication reviews in home-dwelling elderly people receiving polypharmacy.

Background: People with dementia are at high risk for falls. However, little is known of the features causing falls in Alzheimer disease (AD). Our aim was to investigate how participants with AD fall. Methods: In the FINALEX (Finnish Alzheimer Disease Exercise Trial) study, participants’ (n = 194) falls were followed up for 1 year by diaries kept by their spouses. Results: The most common reason for falls (n = 355) was stumbling (n = 61). Of the falls, 123 led to injuries, 50 to emergency department visits, and 13 to fractures. The participants without falls (n = 103) were younger and had milder dementia than those with 1 (n = 34) or ≥2 falls (n = 57). Participants with a Mini Mental State Examination score of around 10 points were most prone to fall. In adjusted regression models, good nutritional status, good physical functioning, and use of antihypertensive medication (incident rate ratio [IRR] 0.68, 95% confidence interval [CI] 0.54–0.85) protected against falls, whereas fall history (IRR 2.71, 95% CI 2.13–3.44), osteoarthritis, diabetes mellitus, chronic obstructive pulmonary disease, higher number of drugs, drugs with anticholinergic properties, psychotropics, and opioids (IRR 4.27, 95% CI 2.92–6.24) were risk factors for falls. Conclusions: Our study provides a detailed account on how and why people with AD fall, suggesting several risk and protective factors.
