Understanding the factors that affect food access and consumption by seniors will lead to improved comprehension and measurement of food security for this subgroup. Semi-structured interviews with low-income, community-living seniors (n = 18) were tape-recorded and transcribed. Interviews were coded and themes were identified using a constant comparison method of analysis. Applying a social ecological framework, three spheres of influence were described: intrapersonal (e.g., health and budget), interpersonal (e.g., informal assistance and socializing) and environmental (e.g., city transportation and grocery stores). Although preliminary, these results demonstrate the importance of interpersonal and environmental factors on food access and security for seniors.
Food insecurity in older adults is influenced by financial constraints, functional disability, and isolation. Twenty-eight social- and community-service providers participated in four focus groups to report (a) perceptions and experiences with food insecurity in their older clients, (b) beliefs about their potential role(s) in promoting food security, and (c) opinions about constraints that influenced these roles. A constant comparison analysis identified key themes. The formal caregivers reported six roles for improving food security: (a) monitoring, (b) coordination, and (c) promoting services, (d) education, (e) advocacy, and (f) providing a social environment. The final theme summarizes these roles as "the need for personalization of service". Social and community service providers are involved in roles that can promote the health of older adults by addressing their food insecurity. Social service providers need to be acknowledged and supported in this health promotion role.
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-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 to 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-high risk of bias, and high heterogeneity across interventions and outcomes. Higher quality research in group-based nutrition education for older adults is needed.

Context: Many older adults fail to meet dietary recommendations for food quality and quantity, which is important to prevent disability and disease. Group and community-based nutrition interventions may help overcome psychosocial, environmental, and behavioural barriers to healthy eating. The EMBOLDEN project uses community co-design, integrating the best available evidence with local knowledge to develop a novel, group-based physical activity, system navigation, and nutrition intervention for older adults. This review synthesizes evidence on nutrition interventions to inform design decisions. Objective: To identify the effectiveness of group-based interventions to promote healthy eating among older adults, to inform the co-design of a targeted, community-based intervention. Study Design: Systematic review. Setting or Dataset: MEDLINE, CINAHL, EMBASE, PsycINFO, and Sociological Abstracts were searched for studies published in English from January 2010 to June 2020. Interventions delivered to groups in community-based settings were eligible; acute and long-term care settings were excluded. Population studied: Healthy, community-dwelling older adults age 55+. Studies were excluded if they targeted specific disease populations. Intervention: Group-based nutrition interventions (alone or in combination), including food access, didactic and/or interactive nutrition education, and education with embedded behaviour change techniques (e.g., goal setting). Weight loss interventions were excluded. Outcome Measures: Primary outcomes were dietary intake, nutritional risk, knowledge, and dietary habits. Results: Thirty-one studies involving 6,723 older adults were included. Studies had generally unclear or high risk of bias. Given heterogeneity across interventions and outcomes, meta-analysis was not possible. Interactive nutrition education may improve dietary intake and knowledge, yet behaviour change strategies likely result in a greater reduction in nutritional risk. Results were shared with EMBOLDEN's Guiding Council of older adults and local health/social service providers to co-design the intervention. Conclusions: Although group-based interventions demonstrate promise in promoting healthier eating among community-dwelling older adults, the available evidence is relatively low quality.Our analysis highlights an opportunity for primary care researchers to advance the science of health promotion and disease prevention nutrition initiatives for older adults.
