An investigation of community-dwelling older adults' opinions about their nutritional needs and risk of malnutrition; a scoping review

Socioeconomic status and older adult's experiences of weight loss: a qualitative secondary analysis

OBJECTIVES

Unintentional weight loss in older adults is common, with 15-20% of those aged >65 having clinically significant weight loss, associated with increased mortality and morbidity. People with socioeconomic disadvantage are more likely to be overweight but also to become frailer in older age. We explore if socioeconomic status impacts upon patients' experience of unplanned weight loss.

METHODS

Qualitative secondary analysis of 23 semi-structured interviews with older adults from two prior studies i), those at risk of frailty ii) those with cancer. Reflexive thematic analysis was conducted, using the lens of the Nutrition Equity Framework, on anonymised transcripts with formation of themes and subthemes, with relationships between themes investigated.

RESULTS

Mean age 73 years, range 65-87; 34% male, Index of Multiple Deprivation Quintiles IMD 1 (n=9), IMD 2 (n=4), IMD 3 (n=3), IMD 4 (n=6), IMD 5 (n=1). Three major themes were identified. 1. 'Healthcare Systems'; interactions with either public health or individual healthcare systems influence patient experiences of weight loss. 2. 'Personal Factors'; that influence a patient's view of weight loss and the likelihood of weight loss prompting help-seeking behaviour 3. 'Can I Change?'; patients' perspectives of their ability to implement change. Factors in each of the themes were understood through motivating (reinforcing) and demotivating (balancing) factors.

CONCLUSIONS

This study demonstrates that there is structural and individual inequity in individual views, identification, and clinical management of weight loss. The consequences of this disproportionately affect the most deprived, further confounding the inequalities that already exist.

The Association of Oral Processing Factors and Nutrient Intake in Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis

CONTEXT

Oral health and food oral-processing issues emerge with functional decline in the older adult population, potentially increasing the risk of malnutrition. Impairment of oral health is associated with poorer nutrition status; however, the relationship between oral factors and the intake of each nutrient remains poorly understood.

OBJECTIVE

The associations between different oral factors and nutrient intakes among community-dwelling older adults were investigated.

DATA SOURCES

A literature search from 5 databases (Web of Science, Scopus, Cochrane Library, Ovid [MEDLINE and Embase], and CINAHL) was completed on February 1, 2022. The search was limited to peer-reviewed articles published between the years 2012 and 2022.

DATA EXTRACTION

Six cross-sectional studies were included in the meta-analysis. Two authors independently completed the data extraction and summarized the study characteristics, factors adjusted for in the statistical analysis, the outcome, and summary statistics of the results.

DATA ANALYSIS

Meta-analyses showed evidence of a significant association between compromised oral factors (namely, denture status, chewing ability, and the number of teeth) with lower energy (weighted mean difference [WMD], -107 kcal d-1 (95% CI, -132 to -81), protein (WMD, -5.2 g d-1; 95% CI, -6.6 to -3.8), fat (WMD, -4.6 g d-1; 95% CI, -6.7 to -2.6), carbohydrate (WMD, -8.8 g d-1; 95% CI, -13.9 to -3.7), and vitamin C intakes (WMD, -12.9 mg d-1; 95% CI, -16.6 to -9.2) in older adults.

CONCLUSION

Oral health can be an indicator of compromised daily energy, protein, fat, carbohydrate, and vitamin C intakes in older adults. However, the small sample size of the studies included in this review and the heterogeneity among macronutrient studies should be considered. Because of the lack of studies covering all aspects of food oral processing (eg, salivary flow rate, tongue pressure), the associations between oral processing and nutrient intake were not thoroughly explored.

Malnutrition Prevalence in Australian Residential Aged Care Facilities: A Cross-Sectional Study

Long-term or residential services are designed to support older people who experience challenges to their physical and mental health. These services play an important role in the health and well-being of older adults who are more susceptible to problems such as malnutrition. Estimates of the significance of malnutrition require up-to-date prevalence data to inform government strategies and regulation, but these data are not currently available in Australia. The aim of this study was to collect malnutrition prevalence data on a large sample of people living in residential aged care facilities in Australia. A secondary aim was to examine the relationship between malnutrition and anthropometry (body mass index (BMI) and weight loss). This prevalence study utilised baseline data collected as part of a longitudinal study of malnutrition in 10 Residential Aged Care facilities across three states in Australia (New South Wales, South Australia, and Queensland). The malnutrition status of eligible residents was assessed by dietitians and trained student dietitians using the Subjective Global Assessment (SGA) with residents categorised into SGA-A = well nourished, SGA-B = mildly/moderately malnourished, and SGA-C = severely malnourished. Other data were extracted from the electronic record. Of the 833 listed residents, 711 residents were eligible and had sufficient data to be included in the analysis. Residents were predominantly female (63%) with a mean (SD) age of 84 (8.36) years and a mean (SD) BMI of 26.74 (6.59) kg/m2. A total of 40% of residents were categorised as malnourished with 34% (n = 241) categorised as SGA-B, and 6% (n = 42) SGA-C. Compared to the SGA, BMI and weight loss categorisation of malnutrition demonstrated low sensitivity and high specificity. These findings provide recent, valid data on malnutrition prevalence and highlight the limitations of current Australian practices that rely on anthropometric measures that under-detect malnutrition. There is an urgent need to implement a feasible aged care resident screening program to address the highly prevalent condition of malnutrition in Australia.

Older adults' perceptions about meat consumption: a qualitative study in Gasabo district, Kigali, Rwanda

BACKGROUND

The global population is increasingly aging, imposing a substantial burden on social and healthcare systems as aging is associated with gradual muscle wasting and functional decline. Consumption of protein-rich foods, such as livestock-based meat, providing high-quality proteins can prevent muscle wasting and related functional decline in older adults. However, there is a lack of data on the older adults' perceptions about meat consumption, particularly in Sub-Saharan Africa.

OBJECTIVE

To explore the perceptions about dietary meat consumption among older adults in Gasabo district, Kigali, Rwanda.

METHODS

We conducted a descriptive qualitative study, using focus group discussions. A total of eight FGDs, lasting between 55 and 80 min, were conducted with gender-mixed groups, including 31 men and 33 women aged ≥ 55 years old. Eight older adults participated in each FGD session, and all discussions were conducted in the local language (Kinyarwanda) using a pre-designed interview guide. The discussions were audio-recorded and transcribed verbatim and translated into English. The transcript was inductively analyzed using thematic analytical process.

RESULTS

Three themes were identified from the data, predominantly related to motives and barriers of meat consumption. The motives of meat consumption included improved quality and taste of the diet, improving own health, and having a social function. Barriers of meat consumption were perceived to be related to health risks, sustainability concerns (depletion of resources), and religious beliefs. Lastly, it was widely perceived that meat was unavailable and economically inaccessible, thus meat consumption was perceived to be associated with improved wealth.

CONCLUSION

The findings revealed a low and declining meat consumption among older adults due to poverty. Improving financial capacity or strategic public health work to improve protein consumption in the elderly is necessary to meet nutritional needs and facilitate healthy aging.

"I see it very much as an end-of-life food" - Barriers to oral nutritional supplement adherence, views from healthy older adults

Malnutrition affects approximately one quarter of UK adults aged 65 years and over. As the global demographic shift continues, malnutrition is expected to increase. Oral nutritional supplements (ONS) are used both to prevent and to treat malnutrition. However, their effectiveness is compromised by poor adherence, and it is not well understood what contributes to this. Therefore, the current research was designed to explore ONS adherence from the parallel perspectives of ONS as a prescribed "medication" and as a food supplement/substitute. Eighteen older adults (13F, 5M; mean age = 73.4 yr; range: 70-80 yr) participated in focus groups (three in-person and one online), to investigate experiences of taking prescribed medications, including dietary supplements, and what should be factors to consider in supporting regular intake of ONS for trial development, as well as any potential improvements to products. Focus group sessions were recorded and then transcribed. Thematic Analysis was applied to the transcripts by the first author, and themes were discussed in depth, using exemplar quotes from participants. Five dominant themes were identified from the data: Disgust, Palatability and Acceptance; End-of-Life Care; Resistance to Medicines; Rituals and Reminders; and Real Food Displacement. Nutritional supplements were characterised as "disgusting", "manufactured", and associated with serious, chronic illness, as well as end-of-life care, in contrast to probiotics which were linked with health and wellness. The sweet taste of ONS was identified as a barrier to intake, given that it is generally associated with a signal to stop eating, and low hunger. As a group, participants tried to "avoid taking medicines", and viewed the need to have them negatively, yet most regularly took prescribed medication and/or vitamin supplements. Participants identified several, rituals and reminders to take medicines, including meal-based, or time-of-day-based prompts (e.g., before, with or after meals). To improve adherence, savoury products were suggested, as well as a more person-centred approach to individual nutritional needs and preferences. Overall, the group discussion mainly identified barriers to intake, but that improving taste, adding to "real food" (not replacing meals), and offering variety of flavour and form (e.g., savoury soups as well as sweet drinks) could be included in future trials to improve appeal and therefore intake. Future work should continue to explore how best to formulate, market and/or prescribe ONS, and how this might vary for malnutrition prevention vs treatment strategies.

Perceptions, Experiences, Barriers and Facilitators Regarding Nutritional Intake of Patients with Chronic Limb Threatening Ischemia: A Qualitative Study

BACKGROUND

Patients with chronic limb threatening ischemia (CLTI) are at high risk for amputation and other cardiovascular adverse events. Nutrition-related symptoms and malnutrition are common in the CLTI population, and lead to worse clinical outcomes. Understanding of the factors influencing nutritional intake is required to determine whether optimization of nutritional intake in this population requires interventions. Therefore, this study aimed to describe perceptions and experiences on nutrition of patients with CLTI, and to identify perceived barriers and facilitators influencing their nutritional intake.

METHODS

In this phenomenological qualitative study, individual semi-structured, face-to-face interviews were conducted with patients with CLTI who lived independently. Interviews were transcribed verbatim, and reflexive thematic analysis was performed.

RESULTS

Twelve participants were interviewed. Five themes were generated: (1) lack of nutritional risk perception, (2) role of nutrition for health, functioning, and surviving, (3) multiple factors influencing nutritional intake, (4) limited nutritional advice, and (5) no intention to change current nutritional intake.

CONCLUSIONS

Patients with CLTI perceive nutritional intake as a necessity to survive and function. Patients express limited risk perception regarding adequate nutritional intake and undernutrition. Nutritional intake is mainly based on non-health-related factors, as habits and taste, and multiple barriers hinder nutritional intake. Patients received no or only limited nutritional advice. Together this leads to an expressed lack of intention to change nutritional intake. Findings of this study stress the urgency for patient-centered nutritional support, to increase nutrition-related knowledge and motivation, to prevent or treat undernutrition, and may improve clinical outcomes in patients with CLTI.

The Malnutrition Awareness Scale for community-dwelling older adults: Development and psychometric properties

BACKGROUND & AIMS

Qualitative studies suggest that malnutrition awareness is poor in older adults. The aim of this study was to develop a questionnaire to quantitatively assess malnutrition awareness in community-dwelling older adults aged 60+ years.

METHODS

The Malnutrition Awareness Scale (MAS) was developed based on the awareness phase of the Integrated-Change model, and included four domains: knowledge, perceived cues, risk perceptions, and cognizance. Twenty-six scale items were developed using results from mainly qualitative research and the expertise of the authors. Items were piloted in 10 Dutch older adults using the Thinking Aloud method to optimize wording. In a feasibility study, annoyance, difficulty and time to complete the MAS and its comprehensibility were tested. After final revisions, the MAS was applied to a large sample to test its psychometric properties (i.e., inter-item correlations, Cronbach's alpha, score distribution) and relevance of the items was rated on a 5-point scale by 12 experts to determine content validity.

RESULTS

The feasibility study (n = 42, 55 % women, 19 % 80+ y) showed that the MAS took 12 ± 6 min to complete. Most participants found it not (at all) annoying (81 %) and not (at all) difficult (79 %) to complete the MAS, and found it (very) comprehensible (83 %). Psychometric analyses (n = 216, 63 % women, 28 % 80+ y) showed no redundant items, but two items correlated negatively with other items, and one correlated very low. After removal, the final MAS consists of 23 items with a min-max scoring range from 0 to 22 (with higher scores indicating higher awareness) and an overall Cronbach's alpha of 0.67. The mean MAS score in our sample (n = 216) was 14.8 ± 3.2. The lowest obtained score was 6 (n = 3) and the highest 22 (n = 1), indicating no floor or ceiling effects. Based on the relevance rating, the overall median across all 22 items was 4.0 with IQR 4.0-5.0.

CONCLUSION

The Malnutrition Awareness Scale is a novel, feasible and reliable tool with good content validity to quantitively assess malnutrition awareness in community-dwelling older adults. The scale is now ready to identify groups with poor malnutrition awareness, as a basis to start interventions to increase malnutrition knowledge and awareness.

Fibre4life: Investigating older adults dietary fibre preferences and the role of targeted educational materials on modulating future dietary fibre intake

The UK has an ever-increasing ageing population; hence, promoting balanced nutrition can have fundamental health and cost benefits. In addition, the majority of older adults' dietary fibre intake is below recommendations and this is despite its well-cited benefits; therefore, more emphasis should be placed on identifying viable age-suitable strategies to overcome the associated dietary fibre-related knowledge gap. Accordingly, one hundred and seventy older adults (65-87 years) were recruited to partake in two survey related studies: (1) initial insights (e.g., dietary fibre-related knowledge, awareness, attitudes and behaviour as well as information preferences) were captured to inform the design of educational materials; and (2) the impact of two targeted educational materials on modulating older adults' future dietary fibre intake was tested. Older adults were willing to learn more about dietary fibre and requested additional information relating to its benefits, recommendations and food-based examples in a clear and accessible format. Therefore, two educational materials (factsheet and practical tips) were developed encompassing key themes. Overall, older adults engaged with the educational materials (regardless of topic and format); thus, demonstrating the potential benefits of this approach going forwards. There was strong agreement with all variables: learning something new, change future dietary fibre intake, format liking, content engaging and share with others as well as the overall experience being cited as useful/helpful. Going forwards, importance should be placed on measuring dietary fibre consumption post engaging with educational materials. In addition, utilising a holistic approach incorporating support from different sources (e.g., health professionals, government, food companies, supermarkets and community) could be fundamental in helping older adults to consume more dietary fibre and subsequently contributing to positive health outcomes.

Dietitians' perceptions of identifying and managing malnutrition and frailty in the community: A mixed-methods study

AIM

This study aimed to explore dietitians' perceptions of their current practice for identifying and managing malnutrition/frailty in the community, to fill an evidence gap.

METHODS

This mixed-methods study involved an online survey distributed to dietitians practising in Australia and New Zealand, and semi-structured interviews with a subset of survey participants. The 34-item survey and interviews explored dietitians' practices for identifying/managing malnutrition and frailty, focusing on the community setting. Survey data were analysed descriptively and some simple association tests were conducted using statistical software. Interview data were analysed thematically.

RESULTS

Of the 186 survey respondents, 18 also participated in an interview. Screening and assessment for malnutrition varied in the community and occurred rarely for frailty. Dietitians reported practising person-centred care by involving clients/carers/family in setting goals and selecting nutrition interventions. Key barriers to providing nutrition care to community-dwelling adults included a lack of awareness/understanding of nutrition by clients and other health professionals (leading to them not participating in or valuing nutrition care), lack of time and resources in the community, and client access to foods/supplements. Enablers included engaging family members/carers and coordinating with other health professionals in nutrition care planning.

CONCLUSION

Reported practices for identifying malnutrition and frailty vary in the community, suggesting guidance may be needed for health professionals in this setting. Dietitians reported using person-centred care with malnourished and frail clients but encountered barriers in community settings. Engaging family members/carers and multidisciplinary colleagues may help overcome some of these barriers.

'Good, honest food': older adults' and healthcare professionals' perspectives of dietary influences and food preferences in older age in Ireland

BACKGROUND

This study aimed to explore older adults' and healthcare professionals' (HCPs) perceptions of dietary influences and food preferences in older age.

METHODS

The research design was phenomenological qualitative description. Semistructured one-to-one interviews and focus groups were held separately with community-dwelling older adults and HCPs involved in care of the older person in Ireland. Data were analysed using inductive thematic analysis.

RESULTS

A total of 47 adults aged 55+ years were recruited (50% male; 49% aged 60-69 years; 28% aged above 70 years), and 26 HCPs were involved, comprising dietitians (n = 8); geriatricians (n = 6); clinical therapists (n = 4); and nurses, pharmacists, catering managers and meal delivery service coordinators (n = 2 each). There are strong desires for 'good, honest food' within the diet for an older person; however, gaps in current nutrition priorities, dietary guidance and health promotion were perceived. There were differences in the perspectives held by HCPs and adults aged 55+ years, as some HCPs centred their discussion around nutrition for preventing sarcopenia, frailty or cognitive decline, whereas many adults aged 55+ years desired foods which promote cardiometabolic health and reflect wider personal health and environmental values. Other themes included the impact of health and lifestyle changes accompanying ageing on dietary priorities, the importance of personal and psychosocial values in determining food choice and the impact of the external food environment on accessibility and shopping experiences.

CONCLUSIONS

Influences on dietary choice for the older person are multifactorial, driven by a range of health, psychological, sociocultural and environmental perspectives. Future nutrition priorities for older adults should encourage health-promoting approaches and not just disease-mitigating efforts.

'Between foods and medicines': A qualitative interview study of patient experiences of the meaning and usage of oral nutritional supplements

The aim of this study was to deepen the understanding of what oral nutritional supplements mean to patients and how this meaning connects to supplement usage, by exploring patient experiences of such supplements. Qualitative interviews were conducted in June 2019-March 2020 with ten patients with malnutrition or at nutritional risk, prescribed oral nutritional supplements by dietitians. Data were thematically analysed using systematic text condensation. Two final categories were identified: 'Oral nutritional supplements are a one-dimensional remedy' and 'Everyday oral nutritional supplement usage is regulated autonomously'. The patients described the meaning of oral nutritional supplements as nutrition. While the supplements could compensate for nutrients not eaten or be part of a helpful compensation strategy, they could not lessen the burden of altered eating. Supplement usage was described as dependent on the acceptance of taste and the priority given to nutrition in everyday life. Usage was greater when nutrients were perceived as needed, such as when striving for higher bodyweight or disease recovery. Usage was lower when a patient's own goals were not increased nutrient intake or bodyweight or when other activities were perceived as more important. Patient experiences indicated that oral nutritional supplements could serve as a remedy for malnutrition, but not for a situation of altered eating. Supplement usage was described as being regulated autonomously based on patient views on the importance of nutrition. Those views were diverse, highlighting the importance of supplement prescribers discussing treatment goals with each patient. A deeper understanding of the meaning of oral nutritional supplements and reasons for their usage from a patient perspective is crucial in order for healthcare to provide appropriate, effective nutrition therapy for malnutrition.

Reflections on recruiting healthcare professionals as research participants: Learning from the ONSPres Study

The involvement of healthcare professionals (HCPs) as research participants is essential to generate high quality evidence for enhancing health services and practice.  Research teams face many challenges in recruiting HCPs for research, and barriers and enablers for interdisciplinary research are not well described in the literature.  The Oral Nutritional Supplement Prescribing Malnutrition Research Study (ONSPres Study) examined malnutrition identification, management, and appropriate oral nutritional supplement prescribing in primary care in Ireland.  The ONSPres Study offers a unique view of recruiting HCPs for research because a range of disciplines were sought for participation in a mixed methods study.  The purpose of this open letter is to describe the experiences of recruitment and participation.  Sixteen general practitioners (GPs) were recruited to participate in one-to-one interviews, eighty health and social care professionals working in community care (including nurses, pharmacists, dietitians, physiotherapists, speech and language therapists, and occupational therapists) were recruited to take part in 12 focus groups, and 31 GPs and trainee GPs were recruited to participate in an education programme developed by the study team.   Strategies required to gain access and reach HCPs differed between disciplines.   Professional networks enhanced access to HCPs working in practice and recruitment was slower and more tailored when those networks were less available to the team.  An interest in malnutrition, to assist in research, to advance patient care, and the opportunity for learning were incentives for the participating HCPs.  Limitations in the diversity of the sample arose, with a bias towards female participants and GPs motivated by an interest in the topic.  It is recommended that study teams collaborate early with relevant HCP disciplines so they can contribute to recruitment planning at project concept and design stages.  To enhance and incentivise HCP participation in research, dedicated time and acknowledgement of participation as continuous professional development is proposed.

Advances in knowledge of screening practices and their use in clinical practice to prevent malnutrition

Malnutrition is common among older adults and is associated with a progressive decline in overall health and increased mortality. With a rapidly ageing population, the detection, prevention and management of malnutrition require urgent attention within health service planning and delivery. Routine screening for malnutrition among older adults in community settings, which addresses aetiological as well as phenotypic factors, is considered an important step for prevention and early intervention. The aim of this review is to summarise current malnutrition screening literature and highlight research that seeks to understand and address community-based approaches to malnutrition screening and management. Key healthcare professionals (HCPs) that encounter community-dwelling older adults include general practitioners (GPs), community-based nurses, community pharmacists and a range of other health and social care professionals including dietitians, physiotherapists, speech and language therapists, and occupational therapists. The key barriers to implementing screening in primary care include lack of knowledge about malnutrition among non-dietetic HCPs, lack of resources allocated to managing malnutrition, lack of access to dietetic services, and poor GP knowledge about oral nutritional supplement prescribing. In addition, older adults have poor insight into the clinical condition and the associated negative health implications. Investment in education among HCPs and public awareness is required, as well as accompanying resources to successfully implement malnutrition screening programmes for community-dwelling older adults.

Social Determinants of Health (Social Risk) and Nutritional Status Among Community-Dwelling Older Adults Living in a Rural Setting: The Atahualpa Project

Background:

Several studies have attempted to clarify the role of social determinants of health (SDH) on nutritional status of older adults, but results are inconsistent due to differences in SDH assessments at different levels of population development. In this study, we assessed this association in community-dwelling older adults living in rural Ecuador. Methods: SDH were measured by the Gijon’s Social-Familial Evaluation Scale (SFES) and nutritional status by the Mini Nutritional Assessment (MNA^®). Multivariate logistic regression models were fitted to assess the association between SDH components and nutritional status. Locally weighted scatterplot smoothing (LOWESS) and a generalized linear model were used to evaluate the potential non-linearity of the association between the Gijon’s SFES and MNA^® scores.

Results:

A total of 295 individuals (mean age: 72.1 ± 7.6 years; 58% women) were enrolled. There was an inverse association between the total Gijon’s SFES and nutritional status (OR: 0.75; 95% C.I.: 0.65-0.86; P < .001). Three of five components of the Gijon’s SFES (family situation, social relationships, and support networks) were inversely associated with nutritional status in multivariate logistic regression models. A LOWESS plot, together with a generalized linear model, showed an inverse linear relationship between the continuous Gijon’s SFES and MNA^® scores. One standard deviation of increase in the continuous Gijon’s SFES score (2.39 points) decreased the MNA^® score by 0.78 points.

Conclusion:

Study results show a significant inverse association between high social risk and a good nutritional status. Components of the Gijon’s SFES measuring social isolation are responsible for this association.

Optimising an intervention to support home-living older adults at risk of malnutrition: a qualitative study

Background

In the UK, about 14% of community-dwelling adults aged 65 and over are estimated to be at risk of malnutrition. Screening older adults in primary care and treating those at risk may help to reduce malnutrition risk, reduce the resulting need for healthcare use and improve quality of life. Interventions are needed to raise older adults’ risk awareness, offer relevant and meaningful strategies to address risk and support general practices to deliver treatment and support.

Methods

Using the Person-based Approach and input from Patient and Public Involvement representatives, we developed the ‘Eat well, feel well, stay well’ intervention. The intervention was optimised using qualitative data from think aloud and semi-structured process evaluation interviews with 23 and 18 older adults respectively. Positive and negative comments were extracted to inform rapid iterative modifications to support engagement with the intervention. Data were then analysed thematically and final adjustments made, to optimise the meaningfulness of the intervention for the target population.

Results

Participants’ comments were generally positive. This paper focuses predominantly on participants’ negative reactions, to illustrate the changes needed to ensure that intervention materials were optimally relevant and meaningful to older adults. Key factors that undermined engagement included: resistance to the recommended nutritional intake among those with reduced appetite or eating difficulties, particularly frequent eating and high energy options; reluctance to gain weight; and a perception that advice did not align with participants’ specific personal preferences and eating difficulties. We addressed these issues by adjusting the communication of eating goals to be more closely aligned with older adults’ beliefs about good nutrition, and acceptable and feasible eating patterns. We also adjusted the suggested tips and strategies to fit better with older adults’ everyday activities, values and beliefs.

Conclusions

Using iterative qualitative methods facilitated the identification of key behavioural and contextual elements that supported engagement, and issues that undermined older adults’ engagement with intervention content. This informed crucial revisions to the intervention content that enabled us to maximise the meaningfulness, relevance and feasibility of the key messages and suggested strategies to address malnutrition risk, and therefore optimise engagement with the intervention and the behavioural advice it provided.

Healthcare professionals' experiences with practice for managing disease-related malnutrition in general practice and proposals for improvement: A qualitative study

BACKGROUND & AIM

Disease-related malnutrition is prevalent in all healthcare settings, including general practice, and is associated with negative consequences for the individual and the community. The aim of this study was to investigate general practitioners and general practice nurses' perceptions of how they manage disease-related malnutrition, and their view on introducing an early intervention against disease-related malnutrition.

METHODS

Content analysis was used to analyse individual semi-structured interviews with the general practitioners (n = 9) and five focus group interviews with the general practice nurses (n = 21) from five general practices in Denmark.

RESULTS

General practice has no tradition for detection of disease-related malnutrition and find that they rarely see patients with unintended weight loss. Nutritional guidance is to a low degree and only randomly performed. Furthermore, most of the health professionals do not have access to nutritional guidance material for patients and lack information about patients' nutrition, when patients when patients receive treatment in the hospital. Suggestions for improvement were handouts with pictures and including nutritional status as a standard in the communication from hospital to general practice. An early intervention against unintended weight loss in specific groups was found feasible. Barriers and facilitators were seen as lack of time, lack of educational opportunities and skills. A financial incentive from the health authorities, and interventions adapted to the individual general practice were among suggested facilitators.

CONCLUSION

Disease-related malnutrition was rarely recognised and managed in general practice. The health professionals found they lacked means to perform nutritional guidance to patients with unintended weight loss. However, the health professionals had suggestions for improvement for an early intervention including handouts for patients. Further research on implementation of early intervention against unintended weight loss in general practice is needed.

Polypharmacy is associated with malnutrition and activities of daily living disability among daycare facility users: A cross-sectional study

ABSTRACT

Polypharmacy influences malnutrition and activities of daily living (ADL) in older individuals owing to side effects such as anorexia. This study aimed to examine whether polypharmacy (5 or more drugs) is associated with malnutrition and ADL disability among daycare facility users.This cross-sectional study was performed in a daycare facility specializing in rehabilitation. Malnutrition was defined according to the Global Leadership Initiative on Malnutrition criteria and ADL disability according to the "criteria for determination of the daily life independence level (bedridden level) of elderly with disabilities."In total, 103 of the 134 included individuals were analyzed. Thirty-three (32.0%) participants were malnourished, 46 (44.7%) had ADL disability, 58 (56.3%) qualified as cases of polypharmacy, and 9 (8.7%) experienced loss of appetite. Multivariable logistic regression analysis showed that polypharmacy was independently associated with malnutrition and ADL disability. Separate analyses of each type of drug revealed that proton pump inhibitors (that impair protein absorption and assimilation), anticonstipation drugs, and antihypertensive drugs were associated with malnutrition, whereas proton pump inhibitors, anticonstipation drugs, antidyslipidemia drugs, and antidiabetic drugs were associated with ADL disability. The only factor related to anorexia was the loss of pleasure of eating, which in turn was related to psychological stress.The side effects of polypharmacy among individuals with malnutrition and ADL disability may include impaired protein absorption and assimilation caused by proton pump inhibitors, but not anorexia. Further multicenter prospective studies are required to confirm these findings.

Sarcopenia versus cancer cachexia: the muscle wasting continuum in healthy and diseased aging

Muscle wasting is one of the major health problems in older adults and is traditionally associated to sarcopenia. Nonetheless, muscle loss may also occur in older adults in the presence of cancer, and in this case, it is associated to cancer cachexia. The clinical management of these conditions is a challenge due to, at least in part, the difficulties in their differential diagnosis. Thus, efforts have been made to better comprehend the pathogenesis of sarcopenia and cancer cachexia, envisioning the improvement of their clinical discrimination and treatment. To add insights on this topic, this review discusses the current knowledge on key molecular players underlying sarcopenia and cancer cachexia in a comparative perspective. Data retrieved from this analysis highlight that while sarcopenia is characterized by the atrophy of fast-twitch muscle fibers, in cancer cachexia an increase in the proportion of fast-twitch fibers appears to happen. The molecular drivers for these specificmuscle remodeling patterns are still unknown; however, among the predominant contributors to sarcopenia is the age-induced neuromuscular denervation, and in cancer cachexia, the muscle disuse experienced by cancer patients seems to play an important role. Moreover, inflammation appears to be more severe in cancer cachexia. Impairment of nutrition-related mediators may also contribute to sarcopenia and cancer cachexia, being distinctly modulated in each condition.

Malnutrition: A Misunderstood Diagnosis by Primary Care Health Care Professionals and Community-Dwelling Older Adults in Ireland

BACKGROUND

Language and communication have an impact on how a clinical condition is treated and experienced, from both the health care professional (HCP) and patient perspective. Malnutrition is prevalent among community-dwelling older adults, yet perceptions of patient understanding of the term malnutrition to date remain underexplored.

OBJECTIVE

This qualitative study explored the use and perceptions of the term malnutrition among HCPs and older adults at risk of malnutrition.

DESIGN

Semi-structured interviews and focus groups were conducted with HCPs and older adults with a prescription for oral nutritional supplements (ONS) in the community, to explore perspectives.

PARTICIPANTS AND SETTING

HCPs with experience of working with older adults were recruited in primary care centers, general practitioner practices, community health organizations, and community pharmacies in County Dublin, Ireland, between 2018 and 2019. Older adults, aged ≥60 years, with a current or previous prescription for ONS were recruited from daycare centers. One-to-one interviews were conducted with general practitioners (n = 16) and patients (n = 13), and focus groups were conducted with other HCPs, including dietitians (n = 22), nurses (n = 22), pharmacists (n = 9), physiotherapists (n = 12), occupational therapists (n = 6), and speech and language therapists (n = 4).

DATA ANALYSIS

Data from interviews and focus groups were transcribed verbatim and analyzed using thematic analysis.

RESULTS

There was mutual agreement between HCPs and patients on the main theme, "malnutrition is a term to be avoided." There were three subthemes with varying input from the different HCP groups and patients: "Malnutrition is a term a patient doesn't want to hear"-malnutrition has negative connotations that imply neglect and stigma; "malnutrition is a clinical term which patients don't understand"-with perceptions that it is better to substitute the term with simpler motivating messages; and "lack of confidence identifying malnutrition"-expressed by non-dietetics HCPs who believed they had insufficient expertise on malnutrition to communicate effectively with patients.

CONCLUSIONS

HCPs and patients perceived negative connotations with the term malnutrition, and HCPs used alternatives in practice. Additional consultation with HCPs and patients is recommended to explore appropriate language for conveying health risks associated with malnutrition. Future research should also address how current communication challenges can be addressed as part of strategic management programs or interventions to prevent and treat malnutrition.
