Involving community-dwelling older adults in activities related to meals as part of a rehabilitation program: a single-blinded cluster-controlled study

Research is still limited on nutrition and quality of life among older adults

Introduction

Globally, the number of older adults is growing exponentially. Yet, while living longer, people are not necessarily healthier. Nutrition can positively impact healthy aging and quality of life (QoL). Two decades ago, nutrition and diet were rarely viewed as key QoL domains, were not part of QoL screening, and QoL studies frequently used unvalidated tools. It is unclear how the nutrition and QoL research area may have since evolved.

Methods

A scoping review was conducted in Pubmed of research with community-living older adults (aged ≥65) from developed economies that included 1 of 29 common, valid QoL instruments, nutrition indices, and was published between 1/2000-12/2022. The review followed published methodology guidance and used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) flow diagram to document identified studies and record number of included/excluded studies (based on scoping review's pre-specified criteria).

Results

Of 258 studies identified initially, 37 fully met scoping review inclusion criteria; only 2 were QoL studies, 30 focused on nutrition, 3 on measurement tool validation/testing, and 2 were other study types. Most studies (n = 32) were among populations outside of North America; majority were conducted in Europe (n = 22) where the EuroQol 5 Dimension (Eq5D) was used in >1/2 the studies. Of 5 North American studies, the 36-Item Short Form Survey (SF-36) was most frequently used (n = 4). Myriad nutrition indices described various aspects of eating, dietary intake, and nutrition status, making comparability between studies difficult. Studies included several different nutrition questionnaires; Mini Nutritional Assessment (MNA) (n = 8) or Mini Nutritional Assessment Short Form (MNA-SF) (n = 5) were used most frequently. The most frequent anthropometric measure reported was Body Mass Index (BMI) (n = 28). Nutrition-related biochemical indices were reported infrequently (n = 8).

Discussion

The paucity of studies over the last two decades suggests research on nutrition and QoL among community-living older adults remains underdeveloped. Valid QoL instruments and nutrition indices are now available. To ensure greater comparability among studies it is important to develop consensus on core indices of QoL and particularly nutrition. Greater agreement on these indices will advance further research to support healthy aging and improve QoL for community-dwelling older adults.

Innovative rehabilitating meal service programs for old people living at home: A randomized controlled pilot study

OBJECTIVE

To test the feasibility of a pilot study for a future definitive trial investigating the effect of different meal service programs for old people living at home.

DESIGN

An 8-week randomized controlled trial was performed.

SETTING

Three municipalities in the Nordic country, Denmark.

SUBJECTS

Danish participants (≥65y) with reduced functionality.

INTERVENTION

Three different meal service programs 1) 24-h meals service, 2) Protein-rich meal service, and 3) Rehabilitation meal service, were developed and compared to standard care.

MAIN MEASURES

The main outcome was study feasibility. Dietary intake, anthropometry, physical function, quality of life, readmissions and adverse events were also evaluated. Comparisons between participants receiving a meal service program and standard care were done by one-way ANOVA, chi-square test and Fishers exact test.

RESULTS

A total of 592 subjects were assessed for eligibility and 13% (76/592) were recruited. Final analysis included 75% (57/76) of participants. The outcome measures seemed acceptable and feasible though eligibility, inclusion, and completion of the intervention were lower than expected. The 24-h meal service program managed to significantly increase the intake of protein (p = 0.049) and energy (p = 0.038) compared to the control group where reductions were seen. No other significant differences were found.

CONCLUSIONS

The pilot study was feasible and several benefits for completers were seen. However, in a future definitive trial, inclusion criteria should be wider, more effort should be put on the time, training and focus of the personal in close contact to the older subjects and the intervention should be less comprehensive and more flexible.

Eating Alone or Together among Community-Living Older People-A Scoping Review

Research on healthy aging commonly concerns problems related to loneliness and food intake. These are not independent aspects of health since eating, beyond its biological necessity, is a central part of social life. This scoping review aimed to map scientific articles on eating alone or together among community-living older people, and to identify relevant research gaps. Four databases were searched, 989 articles were identified and 98 fulfilled the inclusion criteria. In the first theme, eating alone or together are treated as central topics of interest, isolated from adjoining, broader concepts such as social participation. In the second, eating alone or together are one aspect of the findings, e.g., one of several risk factors for malnutrition. Findings confirm the significance of commensality in older peoples' life. We recommend future research designs allowing identification of causal relationships, using refined ways of measuring meals alone or together, and qualitative methods adding complexity.
