GROW: Green Organic Vegetable Gardens to Promote Older Adult Wellness: a Feasibility Study

Community-based physical activity and nutrition interventions in low-income and/or rural older adults: A scoping review

The objective of this review was to identify evidence-based, community-based physical activity (PA) and nutrition-based programs aimed at facilitating health behaviour change among low-income older adults and/or those living in rural/remote areas. This review followed the scoping review methodology proposed by Arksey & O'Malley. The Michie behaviour change wheel was used to categorize intervention types. Of the 2954 retrieved citations, 25 articles met the inclusion criteria. All study interventions demonstrated positive outcomes, including improvements in fruit and vegetable consumption, PA levels, physical function and nutrition knowledge. Study findings highlight that PA and nutrition-based interventions can be effective to facilitate behavior change in low-income and/or rural older adults. Limited research exists looking specifically at older adults living in rural communities, with only two of the 25 included articles including rural study populations.

Subsidized Senior Housing in the US: A Scoping Review

Subsidized senior housing (SSH) is important to support healthy aging among vulnerable subgroups of older adults, yet progress in developing and expanding SSH has been limited. This scoping review had two research questions: (1) What are the trends in SSH empirical studies? (2) What are the main topics in the existing literature on SSH in the US? We reviewed a total of 61 articles and found several notable trends, including a focus on racial and ethnic minorities, cognitive impairment among SSH residents, and collaborative partnerships between housing operators and healthcare providers. More than half of the studies were quantitative, while the rest were qualitative or mixed-methods. The lack of longitudinal or causal design research reflects the limited empirical knowledge of SSH. Four themes emerged: health and well-being, healthcare use and health behaviors, social relations, and housing relocation. We discussed implications for future research and program development efforts in SSH.

Characteristics of health care interventions in affordable senior housing: A scoping review

AIMS

Older adults in affordable senior housing often experience chronic illness and unmet health care needs. This review describes studies reporting the characteristics and primary outcomes of health care interventions for older adults living in affordable senior housing.

DESIGN

A scoping review METHODS: After a systematic search in three databases, a team of investigators screened 1,284 titles and abstracts and selected 31 records with reports on 28 studies for review. Narrative synthesis was used to describe studies of interventions in senior housing and primary outcomes.

RESULTS

Studies typically used observational designs and added clinical staff, such as nurses and social workers, to provide health care interventions in groups (n = 15) or with individuals (n = 13). Outcomes were classified in four groups: wellness, symptom management, health care use, and physical function. A subset of 23 studies (82.1%) reported effective interventions.

IMPACT

Findings identify innovative interventions to promote health in affordable senior housing.

Harvest for Health, a Randomized Controlled Trial Testing a Home-Based, Vegetable Gardening Intervention Among Older Cancer Survivors Across Alabama: An Analysis of Accrual and Modifications Made in Intervention Delivery and Assessment During COVID-19

BACKGROUND

Accelerated functional decline is a concern among older cancer survivors that threatens independence and quality of life. Pilot studies suggest that vegetable gardening interventions ameliorate functional decline through improved diet and physical activity.

OBJECTIVE

The aim of this article was to describe the rationale, recruitment challenges, and enrollment for the Harvest for Health randomized controlled trial (RCT), which will test the impact of a home-based, vegetable gardening intervention on vegetable and fruit consumption, physical activity, and physical functioning among older cancer survivors. Modifications made to the intervention and assessments to assure safety and continuity of the RCT throughout the COVID-19 pandemic also are reported.

DESIGN

Harvest for Health is a 2-year, 2-arm, single-blinded, wait-list controlled RCT with cross-over.

PARTICIPANTS/SETTING

Medicare-eligible survivors of cancers with ≥60% 5-year survival were recruited across Alabama from October 1, 2016 to February 8, 2021.

INTERVENTION

Participants were randomly assigned to a wait-list control or a 1-year home-based gardening intervention and individually mentored by extension-certified master gardeners to cultivate spring, summer, and fall vegetable gardens.

MAIN OUTCOME MEASURES

Although the RCT's primary end point was a composite measure of vegetable and fruit consumption, physical activity, and physical functioning, this article focuses on recruitment and modifications made to the intervention and assessments during COVID-19.

STATISTICAL ANALYSES PERFORMED

χ2 and t tests (α < .05) were used to compare enrolled vs unenrolled populations.

RESULTS

Older cancer survivors (n = 9,708) were contacted via mail and telephone; 1,460 indicated interest (15% response rate), 473 were screened eligible and consented, and 381 completed baseline assessments and were randomized. Enrollees did not differ from nonrespondents/refusals by race and ethnicity, or rural-urban status, but comprised significantly higher numbers of comparatively younger survivors, those who were female, and survivors of breast cancer (P < .001). Although COVID-19 delayed trial completion, protocol modifications overcame this barrier and study completion is anticipated by June 2022.

CONCLUSIONS

This RCT will provide evidence on the effects of a mentored vegetable gardening program among older cancer survivors. If efficacious, Harvest for Health represents a novel, multifaceted approach to improve lifestyle behaviors and health outcomes among cancer survivors-one with capacity for sustainability and widespread dissemination.

Group-based nutrition interventions to promote healthy eating and mobility in community-dwelling older adults: a systematic review

OBJECTIVE

To identify the efficacy of group-based nutrition interventions to increase healthy eating, reduce nutrition risk, improve nutritional status and improve physical mobility among community-dwelling older adults.

DESIGN

Systematic review. Electronic databases MEDLINE, CINAHL, EMBASE, PsycINFO and Sociological Abstracts were searched on July 15, 2020 for studies published in English since January 2010. Study selection, critical appraisal (using the Joanna Briggs Institute's tools) and data extraction were performed in duplicate by two independent reviewers.

SETTING

Nutrition interventions delivered to groups in community-based settings were eligible. Studies delivered in acute or long-term care settings were excluded.

PARTICIPANTS

Community-dwelling older adults aged 55+ years. Studies targeting specific disease populations or promoting weight loss were excluded.

RESULTS

Thirty-one experimental and quasi-experimental studies with generally unclear to high risk of bias were included. Interventions included nutrition education with behaviour change techniques (BCT) (e.g. goal setting, interactive cooking demonstrations) (n 21), didactic nutrition education (n 4), interactive nutrition education (n 2), food access (n 2) and nutrition education with BCT and food access (n 2). Group-based nutrition education with BCT demonstrated the most promise in improving food and fluid intake, nutritional status and healthy eating knowledge compared with baseline or control. The impact on mobility outcomes was unclear.

CONCLUSIONS

Group-based nutrition education with BCT demonstrated the most promise for improving healthy eating among community-dwelling older adults. Our findings should be interpreted with caution related to generally low certainty, unclear to high risk of bias and high heterogeneity across interventions and outcomes. Higher quality research in group-based nutrition education for older adults is needed.

Family Orchards and Health-Related Quality of Life in the Elderly. A Protocol for a Study in Las Hurdes (Spain) Based on an Ethnographic Approach

Demographic evolution is resulting on an aged population increment in Spain. This growth has been more relevant in rural areas, where the population has traditionally lived under hard socio-economic conditions and leveraging the natural resources such as food from family orchards to survive. Studies that have investigated the possibilities and uses of these traditional family orchards today in relation to health-related quality of life in the elderly are scarce. Based on a previous ethnography, this mixed research aims to describe a protocol that will evaluate the effects of the use of traditional family orchards as a daily resource on fitness and quality of life of the elderly population in Las Hurdes (Spain). Body composition, fitness, mental health, health-related quality of life, and activity-related behaviors of participants will be assessed. The outcomes of this study might enable us to design further tailored physical exercise-based interventions using family orchards as an adequate resource to improve the health-related quality of life and fitness of the elderly in rural areas. In addition, the study detailed here might also be applied to other similar rural areas in Spain and worldwide.

Health and Nutritional Beliefs and Practices among Rural Elderly Population: An Ethnographic Study in Western Spain

Background: Demographic transition is causing an increasingly aged society, which has a significant impact on public health strategies. Increases in the size of the elderly cohort create a wider stratification and pose specific challenges. Nutrition and diet are one key issue. This study aims to describe food-related practices, beliefs, and representations of non-institutionalized older adults in rural communities in Extremadura (Western Spain). Method: The ethnographic-based fieldwork was conducted from January to July 2019. Empirical material was collected through different research relationships (semi-structured interviews and informal conversations) and direct observation in various locations in Extremadura―involving a variety of agents associated with different aspects of the nutritional process. Results: Data analysis revealed four major themes: (1) Limitations on choice and quality of food available; (2) food preferences and cooking methods; (3) the role of nostalgia in the construction of taste preferences; and (4) perceptions of what “healthy” food is and how respondents relate to the advice provided by health professionals. Conclusions: Nutritional choices among the group studied presented significant differences from medical advice―which was seen as a series of “bans” that did not carry enough authority to alter the symbolic value attached to their traditions.
