Nutritional Challenges in Nursing Homes: Pilot Study on Macronutrient Intake and Status of Vitamins D and B12. Nutrients 2024; 16:1495. [PMID: 38794733 PMCID: PMC11124101 DOI: 10.3390/nu16101495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 05/07/2024] [Accepted: 05/13/2024] [Indexed: 05/26/2024] Open
Abstract
Older adults living in nursing homes (NH) are considered a population group that could be at risk in terms of nutrition, even more so than their community-dwelling peers. Evidence on the nutritional status of NH residents is scarce, as they are commonly excluded from population-based dietary studies. This is also the case in Slovenia. In the presented pilot study, we assessed the intake of macronutrients as well as the intake and status of vitamin D and vitamin B12 on a sample of NH and NH daycare center users to explore the need for a larger representative study. The pilot study included 37 participants from three Slovenian NH (20 participants) and their daycare centers (17 participants). Daycare centers offer daytime care services for older adults, where users are also provided with major meals during their stay. Intakes of energy and nutrients were estimated by three 24 h dietary records. Fasting blood samples were collected for the assessment of vitamin D and vitamin B12 status. Over 90% of the participants had daily energy and protein intakes below recommendations (reference values: energy intake: males 2100 kcal and females 1700 kcal; protein intake > 1 g/kg body mass). The males' median daily intakes of vitamin D were 1.7 µg (1.5 µg females), and 2.3 µg for vitamin B12 (2.0 µg females). None of the participants had adequate vitamin D intake (>20 µg), and 92.3% males and 87.5% females had inadequate vitamin B12 intake (<4 µg). The prevalence of vitamin D deficiency (serum 25-OH-D conc. < 30 nmol/L) was 100% among NH residents and 53% among NH daycare center users. The prevalence of vitamin B12 deficiency was found in 20% of NH residents. The study results highlighted that certain nutrients might be critical in this population, especially among NH residents; however, a more thorough investigation with the inclusion of other important markers of nutritional status should be performed on a larger, representative sample to support the development and implementation of appropriate public health interventions.

Food provision in Australian aged care homes does not meet protein needs of residents: A call for reform. Nutr Diet 2023. [PMID: 37903654 DOI: 10.1111/1747-0080.12851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 09/26/2023] [Accepted: 10/03/2023] [Indexed: 11/01/2023]
Abstract
AIM Malnutrition is common in older adults in aged care homes, partly due to inadequate protein intake. Menu planning guidelines are available however, adherence to guidelines is unknown. This study aimed to determine; (i) what are the average serving sizes of menu items provided and do they meet recommended portion sizes? (ii) does consumption from a 'typical' menu provide sufficient protein? and (iii) can substituting a 'typical' menu with high-protein options enable residents to achieve protein adequacy? METHODS This study involved 572 residents (73% female; aged 86.4 ± 7.3 years) from 60 aged-care homes in Australia involved in a 2-year cluster-randomised trial. During the trial, food intake was recorded quarterly using visual estimation of plate-waste and 42 061 foods analysed. As part of a secondary analysis of these data, portion sizes of foods were compared to guidelines by calculating the mean (95% confidence interval). Items were deemed inadequate if the upper 95% confidence interval remained below recommended portion sizes. RESULTS On average 47% of breakfast and 80% of lunch/dinner items were below recommended portion sizes. Relative protein intakes, from a typical menu (most consumed foods), was 0.9 g and 0.8 g/kg body weight/day for females and males; both below recommendations. Substituting regular items with higher protein equivalents increased protein intake to 1.3 g and 1.2 g/kg body weight/day, for females and males, respectively. CONCLUSION Aged care homes in Australia are not meeting menu planning guidelines resulting in insufficient protein being provided. Reform to menu guidelines including provision of high-protein foods, will ensure protein adequacy in older adults in aged-care homes.

Guidance for Healthy and More Climate-Friendly Diets in Nursing Homes-Scenario Analysis Based on a Municipality's Food Procurement. Nutrients 2021; 13:4525. [PMID: 34960075 PMCID: PMC8704465 DOI: 10.3390/nu13124525] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2021] [Revised: 12/12/2021] [Accepted: 12/15/2021] [Indexed: 12/27/2022] Open
Abstract
Reducing the climate impact of food provided for residents in nursing homes is challenging, as the diets for older, frail adults must be high in protein content and energy density while at the same time ensuring that the meals are palatable and recognizable. This study aimed at providing guidance on healthy and more climate-friendly diets for nursing homes in the City of Copenhagen. The goal was to decrease greenhouse gas emissions (GHGE) by at least 25% while at the same time providing nutritionally adequate and recognizable menus. First, food purchase data were compiled with datasets matching each food item to a proxy food item and then to databases containing GHGE and nutrient information. Secondly, two diet scenarios were modelled based on current procurement practices, i.e., an energy- and protein-dense diet and a standard protein-dense diet, and converted into guidelines for menu planning. The diets contained less total meat, especially beef, and significantly more pulses, nuts and seeds in order to increase protein content according to recommendations for older adults. Finally, a combined scenario was calculated to reflect the joint climate impact reduction. This kind of innovation in food procurement is required in order to achieve the necessary transition to a sustainable food system.

Can fortified, nutrient-dense and enriched foods and drink-based nutrition interventions increase energy and protein intake in residential aged care residents? A systematic review with meta-analyses. Int J Nurs Stud 2021; 124:104088. [PMID: 34717275 DOI: 10.1016/j.ijnurstu.2021.104088] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 05/26/2021] [Accepted: 09/01/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Food fortification as part of the food-first approach in nursing homes is a strategy that may increase energy and protein intake. OBJECTIVES This review aimed to determine the effect of nutrition interventions using fortification, nutrient-dense or enriched food and/or drinks on energy and protein intake in residents living in nursing homes, compared to the standard menu with or without oral nutritional support products. The secondary aim was to identify and synthesise outcomes of these interventions on weight change, nutritional status, acceptability, cost-effectiveness, and cost-benefit. METHODS A systematic search of seven databases was undertaken. After reviewing all titles/abstracts then full-text papers, key data were extracted and synthesised narratively and through meta-analysis. The quality of included studies was assessed using the Quality Criteria Checklist for Primary Research. RESULTS Of 3,098 articles retrieved, 16 were included, 13 in the meta-analysis. There were 891 participants, with the study duration ranging from four to 26 weeks. The groups receiving the fortified diet had a significantly higher energy intake (Hedges' g = 0.69 (CI 0.36-1.03), p < 0.0001) and protein intake (Hedges' g = 0.46 (CI 0.17-0.74), p = 0.003) compared with the groups receiving the standard menu +/- ONS. The meta-analysis revealed I2 values of 77% for energy (p < 0.0001) and 60% for protein (p = 0.003), indicating considerable statistical heterogeneity across included studies. Benefits to weight and nutritional status of residents were recorded in some studies. Where reported, cost-effectiveness and cost-benefit of menu fortification/supplementation were variable. CONCLUSIONS This systematic review with meta-analyses has shown that fortified menus may significantly increase energy and protein intakes compared with standard menus in nursing homes. As such, the findings of this review support further use of fortified diets in this setting. Further research is warranted comparing food fortification to standard menus, with a particular focus on evaluating the effect on weight, nutritional status and cost-effectiveness of the intervention.

Food and Nutrition Champions in Residential Aged Care Homes Are Key for Sustainable Systems Change within Foodservices; Results from a Qualitative Study of Stakeholders. Nutrients 2021; 13:nu13103566. [PMID: 34684566 PMCID: PMC8541169 DOI: 10.3390/nu13103566] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 10/04/2021] [Accepted: 10/08/2021] [Indexed: 11/30/2022] Open
Abstract
The role of foodservices in aged care is difficult to understand, and strategies to improve the nutritional care of residents are often unsustainable. In particular, food-first strategies such as food fortification are poorly executed in everyday practice and its execution relies upon the foodservice system in aged care homes. The aim of this study was to explore the perspective of staff on the role of foodservices in aged care and gauge the level of skills, education, access, time, and ability to deliver food fortification. Semi-structured interviews were conducted with foodservice managers, foodservice workers, dietitians, carers, and other managers who work in aged care homes across Australia. Participants were recruited purposively through email and through snowballing. Interviews (n = 21) were recorded, transcribed verbatim, and analyzed using inductive thematic analysis. Three themes and six sub-themes were identified. The three themes include the role of foodservices being more than just serving food, teamwork between all staff to champion nutrition, and workplace culture that values continuous improvement. These themes identify how staff perceive the role of foodservices in aged care and provide an important perspective on the long-term sustainability of food fortification strategies and how to improve current practice.

Abstract
The complexity of COVID-19 is also related to the multiple molecular pathways triggered by SARS-CoV-2, which is able to cause type I pneumocyte death, trigger intravascular coagulation, interfere with the renin-angiotensin system, dysregulate iron metabolism, ending with the insurgence of a cytokine storm which may lead to death. Old adults with obesity, hypertension, and diabetes are among the high-risk category groups more prone to SARS-CoV-2 infection. Magnesium has been reported to play a major role both in physiology and in pathology, particularly in elderly people, regulating cytotoxic functions of natural killer (NK) cells and CD8+ T lymphocytes. In spite of the absence of controlled trials, the possibility of magnesium supplementation for supportive treatment in patients with COVID-19 should be encouraged. This could be useful in all phases of the COVID-19 disease.

Meal choice for residential aged care is not yet defined: A scoping review of policies, standards, reports and guidelines. Nutr Diet 2021; 79:169-180. [PMID: 34448340 DOI: 10.1111/1747-0080.12700] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 07/08/2021] [Accepted: 07/26/2021] [Indexed: 11/29/2022]
Abstract
AIM For residents in residential aged care, making choices in relation to food and mealtimes are opportunities to maintain a sense of self and autonomy. It is unknown, however, whether the concept of choice is adequately addressed in texts relating to residential aged care. The purpose of this review is to examine whether residents' right to make choices regarding the meals they eat, is discussed in grey literature including, policies, standards, reports and guidelines, which all impact practice in residential aged care. METHODS Grey literature was located utilising; Google, Google Scholar and hand searching. Texts had to be in reference to residential aged care and were assessed using the Appraisal of Guidelines for Research and Evaluation II and Joanna Briggs Institute tools. RESULTS Twenty-nine texts were included in the final review, consisting of, 12 policies and standards, 12 guidelines and 5 reports. Choice was discussed broadly in the majority of texts, with no definition included for the level of choice that should be provided by residential aged care. The use of alternative meals to provide choice was discussed; however, texts varied in their requirements and recommendations as to what constituted an adequate alternative. CONCLUSIONS The ambiguity surrounding choice affects the practices within residential aged care and ultimately the service provided to residents. With most recommendations being only general in nature, residential aged care homes are not provided with sufficient guidance for meal planning. To ensure residents' right to make choices in their meals is guaranteed, more definitive requirements and recommendations are needed.

Protein-energy malnutrition in older Australians: A narrative review of the prevalence, causes and consequences of malnutrition, and strategies for prevention. Health Promot J Austr 2021; 33:187-193. [PMID: 33783903 DOI: 10.1002/hpja.489] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Accepted: 03/24/2021] [Indexed: 01/13/2023] Open
Abstract
ISSUE ADDRESSED Protein-energy malnutrition (PEM) is a condition of involuntary weight and muscle loss caused by inadequate nutritional intake. In Australia, it is predominantly associated with chronic diseases, as are common in the older population. Given the ageing population of Australia, and the poor outcomes associated with PEM, there is a need to identify the contributing factors, and to explore strategies to prevent PEM. METHODS Two databases were searched for pertinent keywords, including malnutrition, Australia and elderly, with relevant articles selected for inclusion. The citations and references of these articles were also searched for further articles. RESULTS PEM is associated with increasing age and institutionalisation. The contributing factors are multifactorial, and include physiological, pathophysiological and structural causes. PEM is a significant public health issue for Australia, in terms of its consequences on both quality of life for older adults, and the burden on the healthcare system. However, there are strategies that can be implemented at the community, organisation and policy level to prevent PEM. CONCLUSION PEM is a common problem for older Australians, and this has important physiological and public health consequences, especially in the context of the ageing Australian population. However, there is significant scope for preventing PEM. SO WHAT?: Readers can be advised that PEM is a significant public health issue that will increase in importance as the population continues to age. It is important that communities, organisations and governments develop strategies to prevent PEM.

Trace Mineral Intake and Deficiencies in Older Adults Living in the Community and Institutions: A Systematic Review. Nutrients 2020; 12:nu12041072. [PMID: 32294896 PMCID: PMC7230219 DOI: 10.3390/nu12041072] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 04/05/2020] [Accepted: 04/08/2020] [Indexed: 12/31/2022] Open
Abstract
The global population is ageing with many older adults suffering from age-related malnutrition, including micronutrient deficiencies. Adequate nutrient intake is vital to enable older adults to continue living independently and delay their institutionalisation, as well as to prevent deterioration of health status in those living in institutions. This systematic review investigated the insufficiency of trace minerals in older adults living independently and in institutions. We examined 28 studies following a cross-sectional or cohort design, including 7203 older adults (≥60) living independently in 13 Western countries and 2036 living in institutions in seven Western countries. The estimated average requirement (EAR) cut-off point method was used to calculate percentage insufficiency for eight trace minerals using extracted mean and standard deviation values. Zinc deficiency was observed in 31% of community-based women and 49% of men. This was higher for those in institutional care (50% and 66%, respectively). Selenium intakes were similarly compromised with deficiency in 49% women and 37% men in the community and 44% women and 27% men in institutions. We additionally found significant proportions of both populations showing insufficiency for iron, iodine and copper. This paper identifies consistent nutritional insufficiency for selenium, zinc, iodine and copper in older adults.

Abstract
Malnutrition and unintentional weight loss are known to occur in residential aged care facilities (RACFs). The use of oral nutritional supplements (ONS) and high-energy high-protein (HEHP) diets are two foodservice strategies that may be implemented in efforts to reduce unintentional weight loss in RACFs. This observational study aimed to determine whether incorporation of a structured high-energy high-protein diet (sHEHP) into the standard menu could reduce unintentional weight loss in RACF residents. RACFs in this study were facilities that provide long-term care to older adult residents. Weight change, body mass index and subjective global assessment scores of participants were measured at baseline and at six months across five RACFs receiving usual care with ONS or a sHEHP diet. Groups were different at baseline, with a high prevalence of severe malnutrition observed in the ONS group. Over the six-month period, there was a small but statistically significant difference in weight change within the groups: -1.64 ± 3.62 kg, ONS group; 0.56 ± 2.76 kg, sHEHP group, P = 0.0004. Both approaches investigated are feasible, however, future research using high-quality methods is needed to determine the most effective approach to deliver best practice nutrition care for residents into the future.

Abstract
BACKGROUND Nutrient deficiency such as antioxidants is a common problem in the elderly; it can result in different diseases such as cancer. Accordingly, assessment of the dietary intake of antioxidants is necessary to design a specific plan for solving this problem. METHODS This case-control study was conducted on 152 old people (≥60 years) with and without nursing care in nursing care centers in Isfahan, Iran, in 2017. Nutritional assessment was performed by an expert nutritionist using semi-quantitative validated Food Frequency Questionnaire. Nutrition IV software was used as food analyzer. Analysis of covariance and independent t-test were used for data analysis. RESULTS The mean age of the participants was 68.6 ± 4.9 and 68.9 ± 6.1 years in case and control groups, respectively, and the percentage of male/females in these groups was 46.3%/53.7% and 51.4%/48.6%, respectively. Dietary intake of energy, vitamin E, and selenium was significantly higher (P = 0.041; 0.007; 0.017) while beta-carotene intake was significantly lower in the elderly under nursing care than in the control (P = 0.002). CONCLUSIONS The findings indicated that nursing care leads to improved intake of energy, vitamin E, and selenium, while diminished beta-carotene intake in the elderly. Intake of vitamin E, A, C, zinc, and selenium was high among elderly people with and without care, compared with the dietary reference intake. It seems that further studies are required to confirm these findings.

Abstract
Food fortification is used as a nutrition support strategy in aged care homes, for residents who are malnourished or at risk of malnutrition. The aim of this review was to determine the scope and strength of published works exploring relationships between food fortification strategies, mode of delivery and sustainability in aged care homes. Literature from four databases and grey literature was searched. A total of 3152 articles were screened. Seventeen studies were included. Results showed that the majority of studies used pre-made food fortification, rather than fortifying foods on-site. There was heterogeneity across studies, including the mode of delivery and ingredients used for food fortification. Only two studies measured any aspect of costs. No clear sustainable strategies for implementing food fortification in this setting could be identified. Research is required to provide further insight into the acceptability and sustainability of food fortification interventions.

Fat from dairy foods and 'meat' consumed within recommended levels is associated with favourable serum cholesterol levels in institutionalised older adults. J Nutr Sci 2019; 8:e10.

Abstract
CVD is common in older adults. Consumption of ‘meat’ (beef, pork, lamb, game, poultry, seafood, eggs) and dairy foods (milk, cheese, yoghurt) is encouraged in older adults as these foods provide protein and nutrients such as essential fatty acids, Ca, Fe, Zn and vitamins A, D and B12 required for healthy ageing. However, these foods also contain saturated fats considered detrimental to cardiovascular health. To determine the effect of their consumption on CVD risk we assessed associations between fat intake from ‘meat’ and dairy foods and serum cholesterol levels in 226 aged-care residents (mean age 85·5 years, 70 % female). Dietary intake was determined over 2 d using visual estimation of plate waste. Fat content of foods was determined using nutrition analysis software (Xyris, Australia). Fasting serum total cholesterol (TC), LDL-cholesterol and HDL-cholesterol were measured, and the TC:HDL-cholesterol ratio calculated. Associations were determined using random-effect models adjusted for CVD risk factors using STATA/IC 13.0. Total fat and saturated fat from ‘meat’ and dairy foods were associated with higher serum HDL-cholesterol levels, and dairy fat intake and number of servings were associated with a lower TC:HDL-cholesterol ratio. Every 10 g higher intake of fat and saturated fat from dairy products, and each additional serving was associated with a −0·375 (95 % CI −0·574, −0·175; P = 0·0002), a −0·525 (95 % CI −0·834, −0·213; P = 0·001) and a −0·245 (95 % CI −0·458, −0·033; P = 0·024) lower TC:HDL-cholesterol ratio, respectively. Provision of dairy foods and ‘meat’ in recommended amounts to institutionalised older adults potentially improves intakes of key nutrients with limited detriment to cardiovascular health.

Abstract
The consumption of high-Ca, high-protein dairy foods (i.e. milk, cheese, yogurt) is advocated for bone health across the lifespan to reduce the risk of low-trauma fractures. However, to date, the anti-fracture efficacy of dairy food consumption has not been demonstrated in randomised controlled trials but inferred from cross-sectional and prospective studies. The anti-fracture efficacy of dairy food consumption is plausible, but testing this requires a robust study design to ensure outcomes are suitably answering this important public health question. The evidence of skeletal benefits of dairy food consumption is equivocal, not because it may not be efficacious but because the study design and execution are often inadequate. The key issues are compliance with dietary intervention, dropouts, sample sizes and most importantly lack of deficiency before intervention. Without careful appraisal of the design and execution of available studies, precarious interpretations of outcomes may be made from these poorly designed or executed studies, without consideration of how study design may be improved. Dairy food interventions in children are further hampered by heterogeneity in growth: in particular sex and maturity-related differences in the magnitude, timing, location and surface-specific site of bone accrual. Outcomes of studies combining children of different sexes and maturity status may be masked or exaggerated by these differences in growth, so inaccurate conclusions are drawn from results. Until these critical issues in study design are considered in future dairy food interventions, the anti-fracture efficacy of dairy food consumption may remain unknown and continue to be based on conjecture.

Abstract
Residents living in long term care (LTC) who consume a pureed diet tend to have inadequate intake; understanding factors associated with poor intake in this group of residents is not well established. This study examined the adequacy of nutrient intake among LTC residents consuming a pureed diet and the factors associated with this intake (n = 67). Data was collected as part of a cross-sectional study conducted in 32 LTC homes. Weighed food intake was measured on three non-consecutive days and analyzed using Food Processor software. Intake of nutrients were adjusted for intra-individual variability and compared to the Estimated Average Requirement or Adequate Intake for women only. Consumers of a pureed diet had low micronutrient intakes. Multivariate analysis found that the average number of staff assisting with a meal was associated with energy and protein intake. Overcoming eating challenges, careful menu planning and nutrient-dense options for pureed diets in LTC are recommended.

Abstract
OBJECTIVE Modified texture food (MTF), especially pureed is associated with a high prevalence of under-nutrition and weight loss among older adults in long term care (LTC); however, this may be confounded by other factors such as dependence in eating. This study examined if the prescription of MTF as compared to regular texture food is associated with malnutrition risk in residents of LTC homes when diverse relevant resident and home-level covariates are considered. DESIGN Making the Most of Mealtimes (M3) is a cross-sectional multi-site study. SETTING 32 LTC homes in four Canadian provinces. PARTICIPANTS Regular (n= 337) and modified texture food consumers (minced n= 139; pureed n= 68). MEASUREMENTS Malnutrition risk was determined using the Mini Nutritional Assessment short-form (MNA-SF) score. The use of MTFs, and resident and site characteristics were identified from health records, observations, and standardized assessments. Hierarchical linear regression analyses, accounting for clustering, were performed to determine if the prescription of MTFs is associated with malnutrition risk while controlling for important covariates, such as eating assistance. RESULTS Prescription of minced food [F(1, 382)=5.01, p=0.03], as well as pureed food [F(1, 279)=4.95, p=0.03], were both significantly associated with malnutrition risk among residents. After adjusting for age and sex, other significant covariates were: use of oral nutritional supplements, eating challenges (e.g., spitting food out of mouth), poor oral health, and cognitive impairment. CONCLUSIONS Prescription of minced or pureed foods was significantly associated with the risk of malnutrition among residents living in LTC facilities while adjusting for other covariates. Further work needs to consider improving the nutrient density and sensory appeal of MTFs and target modifiable covariates.

Nutritional quality of regular and pureed menus in Canadian long term care homes: an analysis of the Making the Most of Mealtimes (M3) project. BMC Nutr 2017; 3:80. [PMID: 32153857 PMCID: PMC7050785 DOI: 10.1186/s40795-017-0198-3] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2017] [Accepted: 10/03/2017] [Indexed: 12/03/2022] Open
Abstract
Background Long term care (LTC) menus need to contain sufficient nutrients for health and pureed menus may have lower nutritional quality than regular texture menus due to processes (e.g., recipe alterations) required to modify textures. The aims of this study were to: determine adequacy of planned menus when compared to the Dietary Reference Intake (DRI); compare the energy, macronutrients, micronutrients and fibre of pureed texture and regular texture menus across LTC homes to determine any texture, home or regional level differences; and identify home characteristics associated with energy and protein differences in pureed and regular menus. Methods Making the Most of Mealtimes (M3) is a cross-sectional multi-site study that collected data from 32 LTC homes in four Canadian provinces. This secondary analysis focused on nutrient analysis of pureed and regular texture menus for the first week of the menu cycle. A site survey captured characteristics and services of each facility, and key aspects of menu planning and food production. Bivariate analyses were used to compare menus, within a home and among and within provinces, as well as to determine if home characteristics were associated with energy and protein provision for both menus. Each menu was qualitatively compared to the DRI standards for individuals 70+ years to determine nutritional quality. Results There were significant provincial and menu texture interactions for energy, protein, carbohydrates, fibre, and 11 of 22 micronutrients analyzed (p < 0.01). Alberta and New Brunswick had lower nutrient contents for both menu textures as compared to Manitoba and Ontario. Within each province some homes had significantly lower nutrient content for pureed menus (p < 0.01), while others did not. Fibre and nine micronutrients were below DRI recommendations for both menu textures within all four provinces; variation in nutritional quality existed among homes within each province. Several home characteristics (e.g., for-profit status) were significantly associated with higher energy and protein content of menus (p < 0.01). Conclusions There was variability in nutritional quality of menus from LTC homes in the M3 sample. Pureed menus tended to contain lower amounts of nutrients than regular texture menus and both menus did not meet DRI recommendations for select nutrients. This study demonstrates the need for improved menu planning protocols to ensure planned diets meet nutrient requirements regardless of texture.

Mitigating Nutrition and Health Deficiencies in Older Adults: A Role for Food Innovation? J Food Sci 2017; 82:848-855. [PMID: 28267864 DOI: 10.1111/1750-3841.13674] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2016] [Revised: 01/23/2017] [Accepted: 01/31/2017] [Indexed: 12/20/2022]
Abstract
The aim of this review is to describe the factors contributing to diminished food intake, resulting in nutritional deficiencies and associated health conditions in older adults and proposes food innovation strategies to mitigate these. Research has provided convincing evidence of a link between healthy eating patterns and healthy aging. There is a need to target new food product development (NPD) with functional health benefits specifically designed to address the particular food-related needs of older consumers. When developing foods for older adults, consideration should be given to the increased requirements for specific macro- and micronutrients, especially protein, calcium, vitamin D, and vitamin B. Changes in chemosensory acuity, chewing difficulties, and reduced or poor swallowing ability should also be considered. To compensate for the diminished appetite and reduced intake, foods should be energy dense, nutritionally adequate, and, most importantly, palatable, when targeting this cohort. This paper describes the potential of new food product development to facilitate dietary modification and address health deficiencies in older adults.

Abstract
Malnutrition in institutionalised elderly increases morbidity and care costs. Meat and dairy foods are high-quality protein sources so adequate intakes may reduce malnutrition risk. We aimed to determine whether inadequate intakes of meat and dairy foods contribute to malnutrition in institutionalised elderly. This cross-sectional study involved 215 elderly residents (70·2 % females, mean age 85·8 years) from twenty-one aged-care facilities in Melbourne, Australia. Dietary intake was assessed using observed plate waste. Food groups and serving sizes were based on the Australian Guide to Healthy Eating. Nutrient content was analysed using a computerised nutrient analysis software (Xyris). Malnutrition risk was assessed using the Mini Nutrition Assessment (MNA) tool; a score between 24 and 30 indicates normal nutritional status. Data were analysed using robust regression. Mean MNA score was 21·6 (sd 2·7). In total, 68 % of residents were malnourished or at risk of malnutrition (MNA score≤23·5). Protein intake was 87 (sd 28) % of the Australian recommended dietary intake (RDI). Consumption averaged 1 serving each of dairy foods and meat daily. Number of dairy and meat servings related to proportion of protein RDI (both P<0·001), with the former contributing 13 % and the latter 12 % to protein RDI. Number of dairy servings (P<0·001), but not meat servings increased MNA score; each dairy serving was associated with a 1 point increase in MNA score so based on current intakes, on average if residents consumed the recommend four dairy servings (addition of 3 points to MNA score) they would achieve normal nutrition status (>24 points). Provision of meat and dairy foods did not meet recommended levels. On the basis of current dietary intakes in aged-care residents, increasing consumption of dairy foods to the recommended four servings daily ensures protein adequacy and may reduce malnutrition risk in institutionalised elderly, and so reduce risk of comorbidities and costs associated with malnutrition.

Quality Indicators of Nutritional Care Practice in Elderly Care. J Nutr Health Aging 2017; 21:1057-1064. [PMID: 29083448 PMCID: PMC5662708 DOI: 10.1007/s12603-017-0970-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2017] [Accepted: 07/05/2017] [Indexed: 12/15/2022]
Abstract
OBJECTIVES The aim is to explore the effects of antecedent, structural and process quality indicators of nutritional care practice on meal satisfaction and screened nutritional status among older adults in residential care homes. DESIGN Data for this Swedish cross-sectional study regarding older adults living in residential care homes were collected by i) a national questionnaire, ii) records from the quality registry Senior Alert, iii) data from an Open Comparison survey of elderly care in 2013/2014. The data represented 1154 individuals in 117 of 290 Swedish municipalities. MEASUREMENTS Meal satisfaction (%) and adequate nutritional status, screened by the Mini Nutritional Assessment Short Form (MNA-SF), were the two outcome variables assessed through their association with population density of municipalities and residents' age, together with 12 quality indicators pertaining to structure and process domains in the Donabedian model of care. RESULTS Meal satisfaction was associated with rural and urban municipalities, with the structure quality indicators: local food policies, private meal providers, on-site cooking, availability of clinical/community dietitians, food service dietitians, and with the process quality indicators: meal choice, satisfaction surveys, and 'meal councils'. Adequate nutritional status was positively associated with availability of clinical/community dietitians, and energy and nutrient calculated menus, and negatively associated with chilled food production systems. CONCLUSION Municipality characteristics and structure quality indicators had the strongest associations with meal satisfaction, and quality indicators with local characteristics emerge as important for meal satisfaction. Nutritional competence appears vital for residents to be well-nourished.

Abstract
OBJECTIVE The provision of prescribed vitamin D to all aged-care residents has been implemented in New Zealand as part of a government-led falls prevention programme. To our knowledge, there has been no evaluation of this universal programme on vitamin D status and functional and health outcomes. Thus, we aimed to determine 25-hydroxyvitamin D (25(OH)D) concentrations and their predictors in aged-care residents across the country and to investigate whether the government-funded programme was associated with adequate vitamin D status. DESIGN Cross-sectional survey of sociodemographic, biochemical, anthropometric, dietary and health characteristics. Blood samples were analysed for serum 25(OH)D and other biochemical measures. Multiple regression was used to examine predictors of vitamin D status. SETTING Sixteen residential aged-care facilities throughout New Zealand. SUBJECTS Residents aged ≥60 years with residency duration >12 weeks (n 309). RESULTS Mean serum 25(OH)D was 89·9 (95 % CI 85·2, 94·5) nmol/l and monthly supplements (1250 µg (50 000 IU)) were taken by 75 % of all residents. Of those not taking a funded supplement, 65·3 % had serum 25(OH)D 125 nmol/l. CONCLUSIONS Residents taking supplemental vitamin D had adequate vitamin D status; however monitoring of long-term supplementation should be considered, due to the high proportion of participants with high serum 25(OH)D levels.

Abstract
In response to the re-emergence of iodine deficiency in New Zealand, in 2009 the government mandated that all commercially made breads be fortified with iodized salt. There has been no evaluation of the impact of the program on iodine status of the elderly, despite this population group being vulnerable to iodine deficiency or excess. The aim of this study was to describe the iodine status of elderly New Zealanders in residential aged-care homes following the implementation of the bread fortification program. A cross-sectional survey was conducted, involving 309 residents (median age 85 years) from 16 aged-care homes throughout NZ. Information on socio-demographic, anthropometric, dietary and health characteristics were collected. Casual spot urine samples were analysed for urinary iodine concentration (UIC). Blood samples were analysed for serum thyroglobulin, thyroglobulin antibodies, and other biochemical indices. The median UIC (MUIC) of the residents was 72 μg/L, indicating mild iodine deficiency, and 29% had a UIC < 50 μg/L. Median thyroglobulin concentration was 18 ng/mL and 26% had elevated thyroglobulin concentration (>40 ng/mL), suggesting iodine insufficiency. Diuretic use was associated with lower MUIC (p = 0.043). Synthetic thyroxine use was associated with lower odds of having a UIC < 50 μg/L (OR 0.32, p = 0.030)) and lower median thyroglobulin (−15.2 ng/mL, p = 0.001), compared with untreated participants. Frailty was associated with elevated thyroglobulin (p = 0.029), whereas anemia was associated with lower thyroglobulin (p = 0.016). Iodine insufficiency persists in New Zealanders residing in residential aged-care homes despite increasing iodine intake from fortified bread. Research is required to establish optimal iodine intake and status in the elderly.

Abstract
Anemia in elderly population have a great incidence and is related to increased mortality risk. The incidence of nutrition in anemia is about one third of the total. Caloric and protein restriction, iron, vitamin B12, folic deficiency are the causes of nutritional anemia. Protein and energy malnutrition stimulate an increased cytokines production with induction of inflammation, immunodeficiency and anemia. Anorexia and obesity can be associated with anemia due to increased cytokines and hepdicin serum level. Macrophages activity is inhibited and a decrease in red blood cells (RBC), hemoglobin (Hb) concentration due to ineffective erythropoiesis is observed. An adequate energy and protein diet is necessary to reduce inflammation and increase iron absorption. A minimum of 1700 kcal/day and 1.7 gr/kg/day of protein intake are necessary to maintain anabolism in chronic patients to prevent and treat anemia. Iron supplementation by intravenous injection is safe and effective to correct severe iron deficiency. The supplementation of vitamins and oligomineral are useful to reduce oxidative stress and improve RBC longevity. Anemia in elderly could be prevented by an adequate nutrition, a simple and not expensive intervention, and associated to physical exercise reduce the incidence of mortality rate.

Abstract
A systematic review of the literature was conducted to review and evaluate the evidence supporting a liberalized diet for the management of diabetes mellitus in aged care homes and examine the effect of this on glycaemia, nutritional status and diabetes comorbidity risk factors. A 3 step search of eight databases followed by independent data extraction and quality assessment by two authors was undertaken. Studies which compared therapeutic diets to a liberalized diet or observation studies reviewing the effects of therapeutic diets on glycaemia and nutritional status were included. Of the 546 studies identified, six met the inclusion criteria. Methodological quality of the studies was rated poor and the majority concluded no statistically significant change in diabetes management outcomes with a liberalized diet, but modest increases in glycaemia were observed. Inadequate data was available to determine effects of diet change on nutritional status or diabetes risk factors. Overall studies were in support of a liberalized diet but due to the low quality of the evidence and a lack of significant findings it may not be appropriate to extrapolate these conclusions to inform dietetic practice.

Effectiveness of mealtime interventions on nutritional outcomes for the elderly living in residential care: a systematic review and meta-analysis. Ageing Res Rev 2013; 12:967-81.

Abstract
The need to improve the nutrition of the elderly living in long term care has long been recognised, but how this can best be achieved, and whether (and which) intervention is successful in reducing morbidity is less well understood. The aim of this systematic review was to determine the effectiveness of mealtime interventions for the elderly living in residential care. Mealtime interventions were considered as those that aimed to change/improve the mealtime routine, practice, experience or environment. Following comprehensive searches, review and appraisal, 37 articles were included. Inadequate reporting in over half of the articles limited data quality appraisal. Mealtime interventions were categorised into five types: changes to food service, food improvement, dining environment alteration, staff training and feeding assistance. Meta-analysis found inconsistent evidence of effects on body weight of changes to food service (0.5 kg; 95% CI: -1.1 to 2.2; p=0.51), food improvement interventions (0.4 kg; 95% CI: -0.8 to 1.7; p=0.50) or alterations to dining environment (1.5 kg; 95% CI: -0.7 to 2.8; p=0.23). Findings from observational studies within these intervention types were mixed, but generally positive. Observational studies also found positive effects on food/caloric intake across all intervention types, though meta-analyses of randomised studies showed little evidence of any effects on food/caloric intake in food improvement studies (-5 kcal; 95% CI: -36 to 26; p=0.74). There was some evidence of an effect on daily energy intakes within dining environment studies (181 kcal/day, 95% CI: -5 to 367, p=0.06). The need to improve the nutrition of the elderly living in residential long term care is well recognised. This review found some evidence that simple intervention around various aspects of mealtime practices and the mealtime environment can result in favourable nutritional outcomes. Further large scale pragmatic trials, however, are still required to establish full efficacy of such interventions.

Abstract
Background This study examines associations between markers of nutritional status and lymphocyte subsets and seeks to determine if lymphocyte profile is predictive of survival in elderly Australians residing in aged care facilities. Aged yet still ambulatory subjects (n = 88, 73% female) living in low-level care and requiring minimal assistance were studied for 143 weeks. At baseline when participants were aged (mean ± SD) 86.0 ± 5.9 years, dietary intake was determined by 3-day weighed food record, body composition was assessed by dual energy X-ray absorptiometry (DXA) and a venous blood sample was taken. Results At baseline assessment, study participants were consuming nutrient-poor diets and most had symptoms of chronic disease. Although overweight, 40% exhibited sarcopenia. Markers of nutritional status did not relate closely to immune cell numbers (absolute or relative), which on average were within the normal range. Men had lower numbers of CD3+CD4+ cells (CD4+ T cells), a higher proportion of CD3− CD16± CD56± (natural killer (NK) cells) and a higher ratio of NK: CD4+ T cells than women (all P < 0.05). The main age-related changes evident were decreased T cells, particularly low CD4+ T cell counts, and increased numbers of CD19+ (B-cell) and NK cells. During the 143 week duration of follow-up, about one quarter of the study participants died, with death more likely in men than women (P < 0.01). Poor survival was predicted by the presence of decreased numbers of CD4+ T cells (hazard ratio (HR) 0.919, P < 0.01) and expanded numbers of NK cells (HR 1.085, P < 0.05) in the blood, and therefore the presence of a high NK: CD4+ T cell ratio (HR 30.521, P < 0.01). Conclusions The NK: CD4+ T cell ratio may potentially have clinical utility for predicting longevity in elderly populations. Further studies are needed in other elderly populations to confirm this finding.

Abstract
OBJECTIVES [corrected] Low-level aged-care residents are at risk of malnutrition. Oral supplements and fortified foods used to treat malnutrition in the elderly require special preparation and administration by staff. Therefore we aimed to determine if increasing dairy food intake in residents by two serves per day would improve energy and nutrient intakes and prevent malnutrition in residents. DESIGN Prospective intervention study. SETTING 2 intervention and 2 control low-level aged-care facilities in Melbourne, Australia. PARTICIPANTS 130 residents (n = 68 intervention, 78% female, mean age 86.5 years). INTERVENTION This feasibility study was a 4-week intervention where menus were modified to include at least two additional serves of dairy food/day. Control facilities consumed from their regular menus. MEASUREMENTS Mean macro- and micro-nutrient intakes before and after intervention and over the same time period in controls were recorded using observed intake (food served minus waste) and changes over time determined using paired t-tests. Comparison in proportion of residents meeting nutritional requirements was determined using Chi-square distribution test. RESULTS Following intervention, daily increases in mean energy intake (900kJ, P<0.001), protein intake (+25g, P<0.0001), proportion of energy from protein (+4%, P<0.0001) and proportion of estimated energy requirements (EER) (+18%, P<0.0001) were observed, while proportion of energy from fat decreased (-3%, P<0.0001). In controls mean energy intake remained below the EER, and protein intake remained unchanged. Increases in mean daily micronutrient intakes were observed for numerous nutrients including calcium (+679mg, P<0.0001), vitamin D (+1.4μg, P<0.0001), phosphorus (+550mg, P<0.0001), and zinc (+2.8mg, P<0.0001), which remained unchanged in control residents. Calcium and zinc intakes achieved recommended intake levels on the higher dairy diet, but were below recommended levels in controls. Mean sodium intakes remained unchanged. During intervention a greater proportion of residents achieved the EER for energy and the RDI for protein and calcium compared to controls. CONCLUSION Two additional serves of dairy food can significantly improve nutrient intake in aged-care residents and its ease of provision makes it a viable option to potentially prevent malnutrition.

Abstract
OBJECTIVES [corrected] Institutionalized elderly are at high risk of malnutrition, including those residing in low-level aged-care and able to self-feed. We used comprehensive dietary intake assessments to determine the nutritional adequacy of food served to residents and if food waste contributed to insufficient nutrient intakes. DESIGN Cross sectional. SETTING 18 low-level aged care facilities. PARTICIPANTS 199 residents (mean age 86.7 yrs, 76% females). MEASUREMENTS Dietary data using 3-6 day weighed food records. Foods were categorized into main food groups (grains, fruit, vegetables, meats, dairy and 'extra') and quantified based on recommended serving sizes. Chi squared test was used to determine sex differences in proportion of residents below recommended intake levels. RESULTS Residents were provided with sufficient serves of fruit (>2) and meats (>1), but not dairy (<3), vegetables (<5) and grain foods (women only, <4), and excess serves of 'extra' foods (>2). Mean dietary intakes did not meet recommendations for calcium, zinc, magnesium, potassium, folate and dietary fibre with many residents not meeting energy and protein requirements. Sodium intake was up to 3 times higher than recommended, and sugars consumed in excess. Food waste was 0-15% and resulted in men not consuming recommended serves of grain foods. 'Extra' foods contributed substantially to energy intake but provided few of the required nutrients. CONCLUSION Substituting some 'extra' foods for serves of dairy, vegetables and wholegrain foods would improve the nutritional quality of foods, without altering food volume, so is feasible to improve nutritional status in elderly aged-care residents.

Implementing nutrition guidelines for older people in residential care homes: a qualitative study using Normalization Process Theory. Implement Sci 2012; 7:106.

Abstract
Background Optimizing the dietary intake of older people can prevent nutritional deficiencies and diet-related diseases, thereby improving quality of life. However, there is evidence that the nutritional intake of older people living in care homes is suboptimal, with high levels of saturated fat, salt, and added sugars. The UK Food Standards Agency therefore developed nutrient- and food-based guidance for residential care homes. The acceptability of these guidelines and their feasibility in practice is unknown. This study used the Normalization Process Theory (NPT) to understand the barriers and facilitators to implementing the guidelines and inform future implementation. Methods We conducted a process evaluation in five care homes in the north of England using qualitative methods (observation and interviews) to explore the views of managers, care staff, catering staff, and domestic staff. Data were analyzed thematically and discussed in data workshops; emerging themes were then mapped to the constructs of NPT. Results Many staff perceived the guidelines as unnecessarily restrictive and irrelevant to older people. In terms of NPT, the guidelines simply did not make sense (coherence), and as a result, relatively few staff invested in the guidelines (cognitive participation). Even where staff supported the guidelines, implementation was hampered by a lack of nutritional knowledge and institutional support (collective action). Finally, the absence of observable benefits to clients confirmed the negative preconceptions of many staff, with limited evidence of reappraisal following implementation (reflexive monitoring). Conclusions The successful implementation of the nutrition guidelines requires that the fundamental issues relating to their perceived value and fit with other priorities and goals be addressed. Specialist support is needed to equip staff with the technical knowledge and skills required for menu analysis and development and to devise ways of evaluating the outcomes of modified menus. NPT proved useful in conceptualizing barriers to implementation; robust links with behavior-change theories would further increase the practical utility of NPT.

Abstract
PURPOSE OF REVIEW Increasing use of drugs among elderly people has raised concerns about possible negative health outcomes, including malnutrition, associated with polypharmacy. Evidence about the association of polypharmacy with nutritional status is scarce. This review summarizes the relevant evidence regarding polypharmacy and nutritional status in elderly people. RECENT FINDINGS The probability of nutritional problems as a consequence of drugs is highest in elderly people suffering from several diseases. Drug treatment may contribute to poor nutritional status by causing loss of appetite, gastrointestinal problems, and other alterations in body function. Some recently published studies add evidence on possible association between increasing number of drugs and malnutrition. Studies indicate also an association between polypharmacy and weight changes. In addition, there are available studies that have shown deficits in the intake of specific macronutrients and micronutrients (e.g. fiber, glucose, and specific vitamins) for those with a high number of drugs in use. SUMMARY On the basis of available evidence, the role of polypharmacy on nutritional status among elderly people is unclear. Some diseases promote malnutrition; thus, the independent role of drugs for nutritional status is challenging to determine. Longitudinal studies with careful adjustment for underlying diseases are needed to explore association between polypharmacy and malnutrition. Nutritional evaluation should be a routine part of comprehensive geriatric assessment that is conducted ideally in multiprofessional teams, including physician, pharmacist, and dietitian.

Weight loss in elderly women in low-level care and its association with transfer to high-level care and mortality. Clin Interv Aging 2011; 6:311-7.

Abstract
Background The purpose of this study was to determine whether unintentional weight loss in older women predicts an imminent transition out of low-level care (either to higher-level care or by mortality). Methods Fifty-three Australian women, ambulatory while living in low-level care and requiring minimal assistance, were studied. At baseline, when the women were aged (mean ± standard deviation) 86.2 ± 5.3 years, body composition was assessed by dual energy X-ray absorptiometry, dietary intake was determined by a three-day weighed food record, a venous blood sample was taken, and both muscle strength and physical functioning were measured. The women were then followed up for 143 weeks to record the composite outcome of transfer to high-level care or mortality. Results During follow-up, unintended loss of body weight occurred in 60% of the women, with a mean weight loss of −4.6 ± 3.6 kg. Seven women (13.2%) died, and seven needed transfer to high-level care. At baseline, those who subsequently lost weight had a higher body mass index (P < 0.01) because they were shorter (P < 0.05) but not heavier than the other women. Analysis of their dietary pattern revealed a lower dietary energy (P < 0.05) and protein intake (P < 0.01). The women who lost weight also had lower hip abductor strength (P < 0.01), took longer to stand and walk (P < 0.05), and showed a slower walking speed (P < 0.01). Their plasma C-reactive protein was higher (P < 0.05) and their serum albumin was lower (P < 0.01) than women who did not lose weight. Nonintentional weight loss was a significant predictor of death or transfer to high care (hazards ratio 0.095, P = 0.02). Conclusion Weight loss in older women predicts adverse outcomes, so should be closely monitored.

Poor physical function in elderly women in low-level aged care is related to muscle strength rather than to measures of sarcopenia. Clin Interv Aging 2011; 6:67-76. [PMID: 21472094 PMCID: PMC3066255 DOI: 10.2147/cia.s16979] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2011] [Indexed: 12/25/2022] Open
Abstract
Purpose: To determine the prevalence of sarcopenia and investigate relationships among body composition, muscle strength, and physical function in elderly women in low-level aged care. Subjects and methods: Sixty-three ambulatory women (mean age 86 years) participated in this cross-sectional study where body composition was determined by dual energy X-ray absorptiometry (DXA); ankle, knee, and hip strength by the Nicholas Manual Muscle Tester; and physical function by ‘timed up and go’ (TUG) and walking speed (WS) over 6 meters. Body composition data from a female reference group (n = 62, mean age 29 years) provided cut-off values for defining sarcopenia. Results: Elderly women had higher body mass index (P < 0.001), lower lean mass (P < 0.001), and higher fat mass (P < 0.01) than the young reference group. Only a small proportion (3.2%) had absolute sarcopenia (defined by appendicular skeletal muscle mass/height squared) whereas 37% had relative sarcopenia class II (defined by percentage skeletal muscle mass). Scores for TUG and WS indicated relatively poor physical function, yet these measures were not associated with muscle mass or indices of sarcopenia. In multivariate analysis, only hip abductor strength predicted both TUG and WS (both P = 0.01). Conclusion: Hip strength is a more important indicator of physical functioning than lean mass. Measurement of hip strength may therefore be a useful screening tool to detect those at risk of functional decline and requirement for additional care. Further longitudinal studies with a range of other strength measures are warranted.
