Influence of nutritional status on health-related quality of life of non-institutionalized older people

Plasma Acylcarnitines as Metabolic Signatures of Declining Health-Related Quality of Life Measure in Community-Dwelling Older Adults: A Combined Cross-sectional and Longitudinal Pilot Study

BACKGROUND

Health-related quality of life (HRQoL) measures are predictors of adverse health outcomes in older adults. Studies have demonstrated cross-sectional associations between HRQoL measures and blood-based biochemical markers. Acylcarnitines (ACs) are a class of metabolites generated in the mitochondria and are predictive of multiple geriatric syndromes. Changes in ACs reflect alterations in central carbon metabolic pathways. However, the prospective relationship between plasma ACs and declining HRQoL has not been examined. This study aimed to investigate both cross-sectional and longitudinal associations of baseline ACs with baseline and declining EuroQol-5 Dimension/EuroQol Visual Analogue Scale (EQ-5D/EQ-VAS) in community-dwelling older adults.

METHODS

One hundred and twenty community-dwelling older adults with EQ-5D/EQ-VAS measurements at baseline and follow-up were included. We quantified ACs at baseline using targeted plasma metabolomics profiling. Multivariate regressions were performed to examine cross-sectional and longitudinal associations between the measures.

RESULTS

Cross-sectionally, ACs showed no significant associations with either EQ-5D index or EQ-VAS scores. Longitudinally, multiple baseline short-chain ACs were significantly and inversely associated with declining EQ-5D index score, explaining up to 8.5% of variance in the decline.

CONCLUSIONS

Within a cohort of community-dwelling older adults who had high HRQoL at baseline, we showed that higher levels of short-chain ACs are longitudinally associated with declining HRQoL. These findings reveal a novel association between central carbon metabolic pathways and declining HRQoL. Notably, dysregulation in mitochondrial central carbon metabolism could be detected prior to clinically important decline in HRQoL, providing the first evidence of objective biomarkers as novel predictors to monitor HRQoL in nonpharmacological interventions and epidemiology.

Multicomponent Training Improves the Quality of Life of Older Adults at Risk of Frailty

Achieving a high quality of life in older adults can be difficult if they have limited physical function. The aims of this study were to evaluate the relationship between baseline values and variations in body composition, fitness, and nutritional status on health-related quality of life (HRQoL) and to describe the effects of a 6-month multicomponent training (MCT) programme and a 4-month detraining period on HRQoL. A total of 106 participants with limited physical function were included in this study (age: 80.8 ± 5.9 years; 74 females) and were divided into two groups: control (CON) and intervention (TRAIN). HRQoL was measured using the EQ-5D-3L questionnaire and a visual analogue scale (EQ-VAS). Information on body composition, physical fitness, Mediterranean diet adherence, and nutritional status were obtained. Healthier baseline values for body composition, fitness and nutritional status were associated with better HRQoL (explaining 23.7-55.4%). The TRAIN group showed increased HRQoL during this 6-month MCT, showing group-by-time interaction (p < 0.05) and a deleterious effect of detraining. Changes in weight, arm strength, and aerobic capacity contributed to explaining 36% of the HRQoL changes obtained with MCT (all p < 0.05). This MCT improved HRQoL in older adults with limited physical function. However, HRQoL returned to baseline values after detraining. This study highlights the importance of performing ongoing programs in this population.

Health-related quality of life and its association with socioeconomic status and diet diversity in Chinese older adults

Objectives

The study aimed at examining the combined association of socioeconomic status (SES) and diet diversity (DD) with health-related quality of life (HRQoL) and exploring whether DD played a mediating role in the relationship between varied SES and HRQoL among Chinese older persons.

Method

A multi-stage random sampling method was conducted in Shanxi Province of China, with 3,250 older adults participating in this cross-sectional survey. SES was divided into groups by quartiles and DD by means, and these variable groups were combined in pairs to generate a total of eight combinations. The PROCESS macro developed by Hayes was employed for the simple mediation analysis.

Results

Compared with the reference group (those with both high SES and high DD), older adults who were classified to have lower SES or DD had elevated odds of having worse HRQoL: low SES/ low DD (OR = 1.65, 95% CI 1.41-2.92); low SES/ high DD (OR = 1.45, 95% CI 1.17-1.80); middle low SES/ low DD (OR = 1.43, 95% CI 1.24-1.65); middle low SES/ high DD (OR = 1.23, 95% CI 1.03-1.47); upper high SES/ low DD (OR = 1.41, 95% CI 1.21-1.65); and high SES/ low DD (OR = 1.30, 95%CI 1.10-1.53). The mediation analysis revealed that DD mediated the relationship between SES and HRQoL (B=0.011, 95% CI 0.008-0.013), with its indirect effects accounting for 39.29% of the total effects.

Conclusions

These findings highlighted the role of DD as a mediator of the relationship between SES and HRQoL. As DD could be protective, modifiable, and easy for older adults to understand and implement, village clinics and community health stations should work collaboratively to design proper DD intervention measures for better HRQoL.

Mitochondrial Aging and Senolytic Natural Products with Protective Potential

Living organisms do not disregard the laws of thermodynamics and must therefore consume energy for their survival. In this way, cellular energy exchanges, which aim above all at the production of ATP, a fundamental molecule used by the cell for its metabolisms, favor the formation of waste products that, if not properly disposed of, can contribute to cellular aging and damage. Numerous genes have been linked to aging, with some favoring it (gerontogenes) and others blocking it (longevity pathways). Animal model studies have shown that calorie restriction (CR) may promote longevity pathways, but given the difficult application of CR in humans, research is investigating the use of CR-mimetic substances capable of producing the same effect. These include some phytonutrients such as oleuropein, hydroxytyrosol, epigallo-catechin-gallate, fisetin, quercetin, and curcumin and minerals such as magnesium and selenium. Some of them also have senolytic effects, which promote the apoptosis of defective cells that accumulate over the years (senescent cells) and disrupt normal metabolism. In this article, we review the properties of these natural elements that can promote a longer and healthier life.

Interactions between nutrient intake and comorbidities for quality of life in premenopausal and postmenopausal women

OBJECTIVE

This study aimed to identify the associations between nutrient intake and health-related quality of life (HRQOL) in premenopausal and postmenopausal women.

METHODS

Using data from Korean National Health and Nutrition Examination Surveys (2019-2020), EQ-5D-3L, and multivariate logistic and linear regression models, we analyzed the association and interaction between nutrient intake, comorbidities, and HRQOL among 4,027 Korean women.

RESULTS

Nutrient intake levels were lower in postmenopausal women than in premenopausal women. Interactions were observed between numerous nutrient intakes and comorbidities for HRQOL among premenopausal and postmenopausal women. Higher intakes of various nutrients (particularly, folic acid and vitamin A) were related to higher HRQOL scores in premenopausal women with comorbidities (log of inverse HRQOL scores, β = -0.31 [95% confidence interval [CI], -0.58 to -0.05] and β = -0.19 [95% CI, -0.37 to -0.001]) and postmenopausal women with comorbidities (log of inverse HRQOL scores, β = -0.34 [95% CI, -0.61 to -0.07] and β = -0.19 [95% CI, -0.38 to -0.01]), respectively. Regular exercise was associated with a lower risk of mobility problems (odds ratio [OR], 0.59; 95% CI, 0.44-0.81), self-care problems (OR, 0.53; 95% CI, 0.28-0.99), usual activity problems (OR, 0.42; 95% CI, 0.26-0.67), and any problem (OR, 0.71; 95% CI, 0.56-0.90), as well as an increase in HRQOL score (log of inverse HRQOL scores, β = -0.42; 95% CI, -0.68 to -0.16) in postmenopausal women. Smoking was related to a higher prevalence of depression and anxiety problems (OR, 2.51; 95% CI, 1.53-4.13) and any problem (OR, 1.67; 95% CI, 1.11-2.52), as well as a decrease in HRQOL scores (log of inverse HRQOL scores, β = 0.51; 95% CI, 0.14-0.88) in premenopausal women.

CONCLUSIONS

Given the lower nutrient intake levels in postmenopausal women, it is critical to establish HRQOL-improving approaches for this population, including regular exercise, nutrient intake, and smoking cessation.

The potential role of beef and nutrients found in beef on outcomes of wellbeing in healthy adults 50 years of age and older: A systematic review of randomized controlled trials

Shifts in wellbeing and health occur as we age. As life expectancy increases, maintenance of wellbeing and health becomes increasingly important. Nutrients found in beef are associated with outcomes of wellbeing such as physical and cognitive function, lean body mass, and mood in older adults and individuals with chronic disease. However, it is unclear how beef and nutrients found in beef impact wellbeing in healthy adults ≥50 years of age. This study systematically reviewed evidence linking the intake of beef and nutrients found in beef to markers of wellbeing in healthy adults. PubMed, CINAHL, and Web of Science were searched up to August 31, 2021 for eligible randomized controlled trials (RCTs). Nutrients included in the analysis were beef, red meat, dietary protein, essential amino acids, branched chain amino acids, tryptophan, arginine, cysteine, glycine, glutamate, vitamin B6, vitamin B12, choline, zinc, and iron. We identified nine RCTs with results from 55 measurements of markers of wellbeing. An overall positive effect was found of beef and beef's nutrients on wellbeing. There was an overall positive effect of amino acids and protein on wellbeing, with no effect of arginine, vitamin B-12, leucine, and zinc. Physical function was also influenced by beef and nutrients found in beef. Eight of the studies found focused on specific nutrients found in beef, and not beef itself in older adults with one or more chronic diseases. This study identified a need for further research regarding the effect of beef and nutrients found in beef on defined functional outcomes of wellbeing in healthy adults ≥50 years of age.

Association between dietary protein intake and changes in health-related quality of life in older adults: findings from the AusDiab 12-year prospective study

Background

Adequate dietary protein intake is recommended for older adults to optimise muscle health and function, and support recovery from illness, however, its effect on health-related quality of life (HRQoL) is unclear. The aim of this study was to examine the association between total protein intake and different sources of dietary protein and HRQoL in Australians aged 60 years and older over a 12-year period.

Methods

This study used data from the Australian Diabetes, Obesity and Lifestyle study (AusDiab), a 12-year population-based prospective study. The sample included 752 (386 females) adults aged 60 years and older. Protein intake was estimated at baseline (1999/2000) from a 74-item Food Frequency Questionnaire, and HRQoL using the 36-item Short-form Health Survey assessed at baseline (1999/2000) and after 12 years (2011/12). The association between protein intake and change in HRQoL was evaluated using multivariate regression analysis adjusted for relevant confounders. The difference in change in HRQoL between participants with total protein intakes of < 1.0 g/kg/day, intakes of between 1.0–1.2 g/kg/day and intakes of > 1.2 g/kg/day were assessed using one-way ANCOVA.

Results

Total protein intake at baseline was not associated with 12-year changes in physical component summary (PCS) or mental component summary (MCS) scores of HRQoL. Higher animal, red meat and processed animal protein intakes were associated with deteriorations in PCS scores after adjusting for relevant confounders (β = − 0.04; 95% CI: − 0.07, −0.01 ; p = 0.009; β = − 0.05; 95% CI: − 0.08, − 0.01; p = 0.018; β = − 0.17; 95% CI: − 0.31, − 0.02; p = 0.027 respectively). Higher red meat protein intake was associated with deteriorations in MCS scores after adjusting for relevant confounders (β = − 0.04; 95% CI: − 0.08, − 0.01; p = 0.011). There was no difference in 12-year changes in PCS or MCS between participants consuming total protein of < 1.0 g/kg/day, 1.0–1.2 g/kg/day and intakes of > 1.2 g/kg/day.

Conclusion

There was no relationship between total dietary protein intake and HRQoL, but higher protein intakes from animal, red meat and processed animal sources were associated with a deterioration in HRQoL scores over 12 years. Due to the number of associations examined and high drop out of older less healthy participants, further research is required to confirm the associations detected in healthy and less healthy participants, with a view to making protein intake recommendations for older adults.

Nutritional Influences on Locomotive Syndrome

Healthy dietary habits are important to prevent locomotive syndrome (LS). We investigated the relationship between LS and nutritional intake using community health checkup data. We included 368 participants who underwent LS staging, blood sampling, and nutritional intake assessments. Participants (163 adults < 65: 205 older adults ≥ 65) were divided into normal (N; LS stage 0) and LS (L; LS stage 1–2) groups, and blood sample data and nutritional intake were compared between groups. Among adults (N group, 71; L group, 92), low-density lipoprotein cholesterol (LDL-C) was significantly lower, and Vitamin B₁ intake was significantly higher in the L than in the N group; LDL-C, p = 0.033; Vitamin B1, 0.029. Among older adults (N group, 85; L group, 120), hemoglobin (Hb), albumin, and calcium levels were significantly lower, and sodium, monounsaturated fatty acids (MUFA), and n-6 polyunsaturated fatty acids (n-6 PUFA) were significantly higher in the L than the N group; Hb, p = 0.036; albumin, 0.030; calcium, 0.025; sodium; 0.029; MUFA; 0.047, n-6 PUFA; 0.0233). Logistic regression analysis indicated that sodium was the risk factor for the L group (exp (B) 1.001, 95% CI: 1–1.001, p = 0.032). In conclusion, salt intake was associated with LS.

Nutritional Status According to the Short-Form Mini Nutritional Assessment (MNA-SF) and Clinical Characteristics as Predictors of Length of Stay, Mortality, and Readmissions Among Older Inpatients in China: A National Study

Background

Studies are scarce in China that explore the association of nutritional status, measured using the Short-Form Mini Nutritional Assessment (MNA-SF) and biochemical data, on adverse clinical outcomes among older inpatients. In this study, we aimed to determine the prevalence of malnutrition in tertiary hospitals of China and the associations between malnutrition and adverse clinical outcomes.

Methods

This prospective study involved 5,516 older inpatients (mean age 72.47 ± 5.77 years) hospitalized in tertiary hospitals between October 2018 and February 2019. The tertiary hospitals refer to the hospital with more than 500 beds and can provide complex medical care services. The MNA-SF was used to assess nutritional status. Multiple logistic regression and negative binomial regression were used to analyze the relationship between nutritional parameters and risk of hospital length of stay (LoS), mortality, and rehospitalization.

Results

We found that 46.19% of hospitalized patients had malnutrition or malnutrition risk, according to the MNA-SF. Death occurred in 3.45% of patients. MNA-SF scores 0–7 (odds ratio [OR] 5.738, 95% confidence interval [CI] 3.473 to 9.48) were associated with a six-fold higher likelihood of death, and scores 8–11 (OR 3.283, 95% CI 2.126–5.069) with a three-fold higher likelihood of death, compared with MNA-SF scores 12–14 in the logistic regression model, after adjusting for potential confounders. A low MNA-SF score of 0–7 (regression coefficient 0.2807, 95% CI 0.0294–0.5320; P < 0.05) and a score of 8–11 (0.2574, 95% CI 0.0863–0.4285; P < 0.01) was associated with a significantly higher (28.07 and 25.74%, respectively) likelihood of increased LoS, compared with MNA-SF score 12–14. MNA-SF scores 0–7 (OR 1.393, 95% CI 1.052–1.843) and 8–11 (OR 1.356, 95% CI 1.124–1.636) were associated with a nearly 1.5-fold higher likelihood of 90-day readmission compared with MNA-SF scores 12–14 in the logistic regression model. Moreover, hemoglobin level, female sex, education level, former smoking, BMI 24–27.9 kg/m², age 75 years and above, and current alcohol consumption were the main factors influencing clinical outcomes in this population.

Conclusions

Malnutrition increases the risk of hospital LoS, mortality, and 90-day readmission. The use of nutritional assessment tools in all hospitalized patients in China is needed. The MNA-SF combined with hemoglobin level may be used to identify older inpatients with a high risk of adverse clinical outcomes. These findings may have important implications for the planning of hospital services.

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.

Dysphagia Identification and Assessment in Adults in Primary Care Settings-A Canadian Study of Dietitians

Dysphagia affects up to 35% of older adults living in the community and is considered a significant risk factor for malnutrition and aspiration. Early intervention is important, yet dietitian referrals for dysphagia management in primary care are disproportionately low considering the prevalence of dysphagia and its risk factors. As little is known about dietitian's current dysphagia identification and assessment practices in Canada, an online survey was developed. Registered dietitians practicing in primary care were invited to participate. Of the 70 surveys completed, nearly 75% do not have a dysphagia screening process where they practice, and only 8% reported performing noninstrumental, clinical swallowing assessment (CSA). Lack of competency or skills required to complete dysphagia screening and assessment was the most reported barrier. Many respondents were unsure or did not believe CSA fell within their scope of practice, and over 70% reported needing hands-on dysphagia screening and assessment training. Current practices in primary care could be placing individuals with dysphagia, and those at risk, in jeopardy of being overlooked. Initiatives to increase dysphagia awareness, create screening processes, and increase awareness of dietitian's scope of practice are needed to enable primary care dietitians to develop competency in dysphagia screening and assessment.

Metabolomics Signatures of Aging: Recent Advances

Metabolomics is the latest state-of-the-art omics technology that provides a comprehensive quantitative profile of metabolites. The metabolites are the cellular end products of metabolic reactions that explain the ultimate response to genomic, transcriptomic, proteomic, or environmental changes. Aging is a natural inevitable process characterized by a time-dependent decline of various physiological and metabolic functions and are dominated collectively by genetics, proteomics, metabolomics, environmental factors, diet, and lifestyle. The precise mechanism of the aging process is unclear, but the metabolomics has the potential to add significant insight by providing a detailed metabolite profile and altered metabolomic functions with age. Although the application of metabolomics to aging research is still relatively new, extensive attempts have been made to understand the biology of aging through a quantitative metabolite profile. This review summarises recent developments and up-to-date information on metabolomics studies in aging research with a major emphasis on aging biomarkers in less invasive biofluids. The importance of an integrative approach that combines multi-omics data to understand the complex aging process is discussed. Despite various innovations in metabolomics and metabolite associated with redox homeostasis, central energy pathways, lipid metabolism, and amino acid, a major challenge remains to provide conclusive aging biomarkers.

Association of low back pain with muscle weakness, decreased mobility function, and malnutrition in older women: A cross-sectional study

Background

Low back pain (LBP) and decreased mobility function are common problem among older people. Muscle weakness has been reported as a risk factor for these conditions, and exercise therapy can improve them. We created a novel exercise device that also measures abdominal trunk muscle strength. Malnutrition has also emerged as a major problem among older people. Muscle is a direct key linking decreased mobility function and malnutrition. This study aimed to examine the associations of LBP with not only decreased physical function and muscle weakness but also nutritional status of older people.

Methods

We examined the associations of LBP with muscle weakness, decreased mobility function (locomotive syndrome [LS]), and malnutrition among older women. The study included 101 female patients aged 60 years or older scheduled to undergo surgery for degenerative lower extremity diseases. Preoperatively, physical tests including abdominal trunk muscle strength assessment using the device and laboratory tests were conducted. Subjects with LBP (numerical rating scale ≥2; range, 0–4) during the preceding month were allocated to the LBP group (n = 36). Other subjects were allocated to the non-LBP group (n = 65).

Results

The LBP group had lower abdominal trunk and knee extensor muscle strength, lower serum albumin, and hemoglobin levels as blood biomarkers associated with malnutrition risk, and higher LS test scores than the non-LBP group. A multivariate analysis showed that abdominal trunk muscle weakness and advanced LS were associated with LBP. LBP intensity was negatively correlated with abdominal trunk and knee extensor muscle strength and positively correlated with the LS test score. The serum hemoglobin level was negatively correlated with the LS test score.

Conclusion

Abdominal trunk muscle weakness and decreased mobility function were associated with LBP among older women.

Relationship between Anticholinergic Burden and Health-Related Quality of Life among Residents in Long-Term Care

OBJECTIVES

Anticholinergic burden defined by the Anticholinergic Risk Scale (ARS) has been associated with cognitive and functional decline. Associations with health-related quality of life (HRQoL) have been scarcely studied. The aim of this study was to examine the association between anticholinergic burden and HRQoL among older people living in long-term care. Further, we investigated whether there is an interaction between ARS score and HRQoL in certain underlying conditions.

DESIGN AND PARTICIPANTS

Cross-sectional study in 2017. Participants were older people residing in long-term care facilities (N=2474) in Helsinki.

MEASUREMENTS

Data on anticholinergic burden was assessed by ARS score, nutritional status by Mini Nutritional Assessment, and HRQoL by the 15D instrument.

RESULTS

Of the participants, 54% regularly used ARS-defined drugs, and 22% had ARS scores ≥2. Higher ARS scores were associated with better cognition, functioning, nutritional status and higher HRQoL. When viewing participants separately according to a diagnosis of dementia, nutritional status or level of dependency, HRQoL was lower among those having dementia, worse nutritional status, or being dependent on another person's help (adjusted for age, sex, comorbidities). Significant differences within the groups according to ARS score were no longer observed. However, interactions between ARS score and dementia and dependency emerged.

CONCLUSION

In primary analysis there was an association between ARS score and HRQoL. However, this relationship disappeared after stratification by dementia, nutritional status and dependency. The reasons behind the interaction concerning dementia or dependency remain unclear and warrant further studies.

Associations Between Nutritional Status, Sociodemographic Characteristics, and Health-Related Variables and Health-Related Quality of Life Among Chinese Elderly Patients: A Multicenter Prospective Study

Background: Studies that explore the nutritional status, sociodemographic factors, mental health variables, and physical health variables that affect the health-related quality of life (HRQoL) of elderly patients are scarce in China. Objective: This study aimed to examine the association between health-related quality of life (HRQoL) and nutritional status, sociodemographic characteristics, and health-related variables among Chinese elderly patients. Materials and Methods: Participants were recruited from six tertiary-level hospitals in six provinces or municipalities/cities throughout China from October 2018 to February 2019: a total of 9,996 participants aged 65 years and older were enrolled. The nutritional status and HRQoL were measured using the Mini Nutritional Assessment-Short Form (MNA-SF) and the EuroQoL Five-Dimension Visual Analog Scale, respectively. BMI was taken using standard measurement protocols. Sociodemographic characteristics included age, sex, education, marital status, ethnicity, smoking, alcohol drinking, and current residence. Mental and physical health variables such as frailty and depression were assessed using validated tested instruments. Multiple linear regression analysis was used to analyze whether the nutritional status, sociodemographic characteristics, and health-related variables were associated with HRQoL. Results: According to the MNA-SF scores at the 30- and 90-day follow-up, 9.7% and 9.1% of participants were malnourished, respectively. Higher MNA-SF scores were related to higher HRQoL scores in older patients (regression coefficient; 95% confidence interval) both at the 30-day (0.660; 0.499-0.821) and 90-day (0.622; 0.434-0.809) follow-up. However, there were no significant associations between the body mass index values and HRQoL. Sociodemographic characteristics (such as age, smoking, and current residence), physical health variables (frailty, urinary function, defecation function, sleeping condition, and falling accidents in the past 12 months), and mental health variables (depression) were the main factors influencing HRQoL in this group. Conclusion: There are several factors associated with HRQoL among the population derived from this investigation of a representative sample of the Chinese hospitalized elderly population in tertiary hospitals. These findings could have major importance for the planning of "active aging" policies and programs. Trial Registration: Chinese Clinical Trial Registry, ChiCTR1800017682, registered August 9, 2018.

Beliefs about inevitable decline among home-living older adults at risk of malnutrition: a qualitative study

BACKGROUND

Approximately 14% of free-living adults aged ≥65 years are at risk of malnutrition. Malnutrition screen and treat interventions in primary care are few, show mixed results, and the advice given is not always accepted and followed. We need to better understand the experiences and contexts of older adults when aiming to develop interventions that are engaging, optimally persuasive and relevant.

METHODS

Using the Person-based Approach, we carried out 23 semi-structured interviews with purposively selected adults ≥65 years with chronic health or social conditions associated with malnutrition risk. Thematic analysis informed the development of key principles to guide planned intervention development.

RESULTS

We found that individuals' beliefs about an inevitable decline in appetite and eating in older age compound the many and varied physical and physiological barriers that they experience. Also, we found that expectations of decline in appetite and physical ability may encourage resignation, reduce self-efficacy to overcome barriers, and reduce motivation to address weight loss and/or recognise it as an issue that needs to be addressed. Fear of loss of independence may also reduce the likelihood of asking general practitioners for advice.

CONCLUSIONS

The key findings identified include a sense of resignation, multiple different barriers to eating and a need for independence, each underpinned by the expectation of a decline in older adulthood. Interventions need to address misperceptions about the inevitability of decline, highlight how and why diet recommendations are somewhat different from recommendations for the general population, and suggest easy ways to increase food intake that address common barriers.

Malnutrition Prevalence and Burden on Healthcare Resource Use Among Spanish Community-Living Older Adults: Results of a Longitudinal Analysis

PURPOSE

Little is known about the economic burden that malnutrition or its risk imposes on community-dwelling older adults. Using cross-sectional and longitudinal analyses, we assessed the impact of malnutrition risk on healthcare utilization and costs in a cohort of older adults living in Spanish community.

PATIENTS AND METHODS

Data from 1660 older (range 66-98 years), community-living adults participating in the Toledo Study on Healthy Ageing, waves 2 (year 2011-2013) and 3 (year 2015), were analyzed. Nutritional status categories were defined according to the Global Leadership Initiative on Malnutrition (GLIM) criteria, using a two-step approach. First, screening for malnutrition risk. Once positive, individuals were classified as malnourished according to some phenotypic (body mass index, grip strength, and unintentional weight loss) and etiologic (disease burden/inflammation and reduced food intake or assimilation) criteria. Outcomes assessed included healthcare resources (hospital admissions, number of hospitalizations, length of hospital stay per hospitalization, and number of medications).

RESULTS

Fifteen percent of the population was found to be at risk of malnutrition, while 12.6% was malnourished. Overall, patients from both groups were older, had lower functional status, and had more comorbidities compared to well-nourished counterparts (p<0.05). Results of our cross-sectional analysis showed that being at-risk/malnourished was associated with greater medication utilization, higher rates of hospital admission and longer stays, and higher hospitalization costs. However, when adjusting for covariates, malnutrition/risk was associated only with higher hospitalization costs (range: 11-13%). Longitudinal analysis results indicated that malnutrition/risk was significantly associated with more frequent hospitalizations, longer lengths of stay, higher hospitalization costs, and polypharmacy at follow-up.

CONCLUSION

Malnutrition or its risk, found in over one of four older adults in the Toledo community, was associated with higher healthcare resource use and increased costs. Such findings suggest that malnutrition risk-screening for older adults, and provision of nutrition counseling and care when needed, hold potential to improve their health and to lower costs of care in the Spanish healthcare system.

Trace Mineral Intake and Deficiencies in Older Adults Living in the Community and Institutions: A Systematic Review

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.

Risk Factors and Number of Falls as Determinants of Quality of Life of Community-Dwelling Older Adults

BACKGROUND AND PURPOSE

In older adults, the psychological impact and effects related to the loss of functional capacity are directly related to perceived quality of life (QOL). The predictors of better QOL are increased physical activity, lower prevalence of overweight, lower cases of depression, and lower rate of reported alcohol abuse. On the contrary, the predictors of decreased QOL are female gender, comorbidity, deficient nutritional condition, polypharmacy, loss of mobility, depression and dependency, poor economic conditions, and social isolation and loneliness. Furthermore, QOL in older adults is more dependent on the number of falls than comorbidity. The objective was to investigate the determinants of perceived QOL among independent community-dwelling older adults and to quantify the influence of number of falls and number of risk factors on QOL.

METHODS

This is a cross-sectional study of 572 older adults (>70 years of age) seen in 10 primary care centers in La Ribera, Valencia, Spain. Comprehensive geriatric assessment was done by 4 nurses in primary care centers. Functional status and sociodemographic and clinical variables were collected. Quality of life was assessed with the EQ-5D scale.

RESULTS

Females predominated (63.3%). Mean age (standard deviation) was 76.1 (3.9) years. The male gender (β = .09; 95% confidence interval [CI]: 0.05-0.13) was found to be predictive of better QOL, together with physical activity (β = .04; 95% CI: 0.02-0.06), while the use of drugs affecting the central nervous system (β = -.08; 95% CI: -0.12 to -0.03), overweight (β = -.06; 95% CI: 0.1 to - 0.02), comorbidity (β = -.09; 95% CI: -0.13 to -0.05), the presence of fall risk factors (β = -.02; 95% CI: -0.03 to 0.01), and the number of previous falls (β = -.03; 95% CI: -0.06 to 0.01) had a negative impact upon the EQ-5D Index score.

CONCLUSIONS

If perceived QOL is used as an indicator of the success of intervention programs, certain factors accompanying the adoption of measures for the prevention of falls may mask the results (failure or success) of the intervention. Because most determinants of QOL are modifiable and physical activity has the potential to improve QOL, this research suggests that physical activity programs should be a component of health care for older adults.

Associations between Nutritional Status, Frailty and Health-Related Quality of Life among Older Long-Term Care Residents in Helsinki

OBJECTIVES

The aim of this study was to examine how nutritional status modifies the association between frailty and health-related quality of life (HRQoL) among older nursing home residents. We also investigated how residents' energy intake is linked to frailty score.

DESIGN AND PARTICIPANTS

A total of 486 older (> 65 years of age) nursing home residents living in Helsinki, Finland were included to this cross-sectional study.

METHODS

We collected data on the residents' background information, HRQoL by 15D, nutritional status by Mini Nutritional Assessment (MNA), frailty status (Fried's phenotype criteria; pre-frail: 1-2 criteria and frail: 3-5) and energy intake (one- or two-day food records).

RESULTS

The frail residents were more often malnourished and had lower HRQoL than those in the prefrail group. Energy and protein intakes were significantly lower among frail women than prefrail women. Energy intake was linearly associated with frailty points. When residents in the frail and prefrail groups were divided according to their nutritional status, both nutritional status and frailty were associated with HRQoL, but there was no interaction.

CONCLUSIONS

Both nutritional status and frailty were associated with HRQoL, and lower energy intake indicated a higher frailty score. An adequate energy intake may promote residents' HRQoL and prevent frailty in long-term care.

A Review of the Development and Application of Generic Preference-Based Instruments with the Older Population

Older people (aged 65 years and over) are the fastest growing age cohort in the majority of developed countries, and the proportion of individuals defined as the oldest old (aged 80 years and over) living with physical frailty and cognitive impairment is rising. These population changes put increasing pressure on health and aged care services, thus it is important to assess the cost effectiveness of interventions targeted for older people across health and aged care sectors to identify interventions with the strongest capacity to enhance older peoples' quality of life and provide value for money. Cost-utility analysis (CUA) is a form of economic evaluation that typically uses preference-based instruments to measure and value health-related quality of life for the calculation of quality-adjusted life-years (QALYS) to enable comparisons of the cost effectiveness of different interventions. A variety of generic preference-based instruments have been used to measure older people's quality of life, including the Adult Social Care Outcomes Toolkit (ASCOT); Health Utility Index Mark 2 (HUI2); Health Utility Index Mark 3 (HUI3); Short-Form-6 Dimensions (SF-6D); Assessment of Quality of Life-6 dimensions (AQoL-6D); Assessment of Quality of Life-8 dimensions (AQoL-8D); Quality of Wellbeing Scale-Self-Administered (QWB-SA); 15 Dimensions (15D); EuroQol-5 dimensions (EQ-5D); and an older person specific preference-based instrument-the Investigating Choice Experiments Capability Measure for older people (ICECAP-O). This article reviews the development and application of these instruments within the older population and discusses the issues surrounding their use with this population. Areas for further research relating to the development and application of generic preference-based instruments with populations of older people are also highlighted.

Energy Intake and Severity of Dementia Are Both Associated with Health-Related Quality of Life among Older Long-Term Care Residents

Our aim was to investigate how energy intake modifies the association of the stage of dementia with health related quality of life (HRQoL) among institutionalized older people. A cross-sectional sample of 538 older long-term care residents with dementia in Helsinki, Finland were assessed with HRQoL (15D), energy intake (from one to two days), and the stage of dementia by the clinical dementia rating (CDR) scale. The energy intakes were standardized by z-scores to include both men and women in the same analyses. Severity of dementia was associated with HRQoL (15D index in CDR 0.5–1: 0.65 (0.11), CDR 2: 0.60 (0.10), CDR 3: 0.52 (0.10)). When the three groups of dementia severity were divided according to their energy intake quartiles, there was an association between the HRQoL and the stage of dementia (p < 0.001) and energy intake (p = 0.013); however, no interaction was observed (p = 0.30). While partial correlation analysis showed that energy intake correlated with HRQoL among residents with very mild/mild or moderate dementia, this was not observed among those with severe dementia. In moderate dementia, the dimensions of mobility and usual activities correlated significantly with higher energy intake. Both energy intake and severity of dementia are associated with HRQoL.

Selenium, aging and aging-related diseases

Selenium is an essential trace element in the human body and plays an important role in the body via selenoprotein, which contains selenium. Selenoproteins (glutathione peroxidase, thioredoxin reductase, methionine sulfoxide reductase1 and endoplasmic reticulum-selenoproteins, etc.) have antioxidant effects and are involved in regulating antioxidant activities. Aging is an inevitable process and is always accompanied by aging-related diseases. Reactive oxygen species are important initial factors in aging and aging-related diseases. Selenium contributes to the alleviation of reduced reactive oxygen species-mediated inflammation, reduced DNA damage and prolonged telomere length and thereby plays roles in fighting aging and preventing aging-related diseases. In the elderly, aging-related diseases include neuropsychiatric diseases, tumors, cardiovascular diseases, and skin aging, among others. Selenium supplementation is an important strategy for anti-aging and the prevention of aging-related diseases and is of great significance for the elderly. However, with the accumulation of related research, selenium supplementation does not necessarily contribute to the prevention of aging and aging-related diseases. It is believed that a low level of selenium is beneficial to the human body. Thus, the effect of selenium on human aging and aging-related diseases is still controversial. This paper reviews the research progress and objective role of selenium in aging and aging-related diseases.

Nutrition-related parameters predict the health-related quality of life in home care patients

INTRODUCTION

There is evidence that nutritional status is one of the major factors affecting quality of life. Low quality of life is an important reason that reflects the risk of malnutrition as well as dependency and frailty.

OBJECTIVE

The present study aimed to examine nutritional risk factors and sociodemographic features affecting health-related quality of life in home care patients.

MATERIALS AND METHODS

The data of 209 adult or elderly eligible subjects were evaluated in the study. A general questionnaire including sociodemographic and nutritional characteristics, 'Mini Nutritional Assessment (MNA)', 'Short Form-36 (SF-36) health related life quality scale' and '24-hour dietary recall' were applied with face-to-face interview. Anthropometric measurements were performed using standard measurement protocols and, height and weight measurements of bedridden patients were calculated by equality formulas.

RESULTS

While 52.6% of patients were malnourished according to the MNA, only 7.7% were underweight according to the body mass index (BMI). The SF-36 summary component scores (physical and mental component summary scale scores) of malnourished patients were significantly lower than patients at risk of malnutrition or normal (p < 0.05). There were significant positive correlations between SF-36 physical component summary scale scores were significantly correlated with MNA scores (r = 0.517), BMI (r = 0.140) and daily dietary macronutrient intake (energy (r = 0.328), protein (r = 0.165), carbohydrate (r = 0.305), fat (r = 0.275) and fiber (r = 0.268)) (p < 0.05). Besides there were significant positive correlation between SF-36 mental component summary scale scores and MNA scores (r = 0.719), BMI (r = 0.318), daily dietary macronutrient intake (energy (r = 0.388), protein (r = 0.204), carbohydrate (r = 0.335), fat (r = 0.365) and fiber (r = 0.349)) (p < 0.05). It was also determined that MNA had the greatest positive effect and 'having a caregiver' had the greatest negative effect on the physical and mental component summary scale scores.

CONCLUSION

Periodic nutritional screening of home care patients is important and necessary for early nutritional intervention and thus prevention of morbidity and mortality.

The relationship between malnutrition and quality of life in haemodialysis and peritoneal dialysis patients

BACKGROUND

One of the most important factors affecting the quality of life of chronic kidney disease (CKD) patients is nutrition. Prevention of malnutrition increases patients' quality and length of life. In this study, we aimed to determine the frequency of malnutrition, quality of life, and the relationship between them in patients with end-stage renal disease (ESRD).

METHOD

The study was conducted with a total of 60 CKD patients including 50 haemodialysis patients and 10 peritoneal dialysis patients. Patients' data associated with socio-demographics, body mass index (BMI), waist circumference, triceps skin-fold thickness (TSFT), pre-dialysis systolic and diastolic blood pressure, Kt/V and urea reduction ratio (URR) values, laboratory parameters, Mini-Nutritional Assessment-Short Form (MNA-SF) and European Quality of Life 5-Dimensions (EQ5D) scale were recorded.

FINDINGS

Of the total 60 patients; 27 were male (45%), 33 were female (55%), 83.3% were receiving haemodialysis treatment (HD), and 16.7% were receiving peritoneal dialysis treatment (PD). The mean MNA-SF score was 10.4 ± 2.8 in the HD group and 10.5 ± 2.9 in the PD group; there was no difference between the scores of the HD and PD groups. The mean EQ5D score was 0.60 ± 0.29 in the HD group and 0.68 ± 0.33 in the PD group, no significant difference was found between the HD group and the PD group. The quality of life was found lower in malnourished group (p=0.001).

CONCLUSION

The quality of life needs to be increased by early diagnosis and treatment of malnutrition in patients at risk.

Associations between Nutritional Status and Health-Related Quality of Life among Long-Term Care Residents in Helsinki

OBJECTIVES

We evaluated the associations between nutritional status and health-related quality-of-life (HRQoL) among older long-term care residents in Helsinki.

DESIGN AND PARTICIPANTS

All 3767 older (≥65 years) long-term care residents in Helsinki in 2017 were invited to participate in this cross-sectional study. After refusals and exclusions of residents without sufficient information, 2160 residents remained.

MEASUREMENTS

Data on characteristics, nutritional status (Mini Nutritional Assessment, MNA) and HRQoL (15D) were collected by trained nurses.

RESULTS

Of the participants, 64% were at-risk of malnutrition and 18% suffered from malnutrition. Residents in the "malnourished" group were more dependent in activities of daily living (ADL) functioning, suffered more often from dementia, had lower cognitive level, used less medications, and were eating more often inadequately. HRQoL was statistically significantly associated with MNA total score in both female and male residents. There was a curvilinear correlation between MNA and 15D score in females: 0.50 (95% CI 0.46 to 0.53) and males: 0.56 (95% CI 0.50 to 0.61). In partial correlation analysis, all dimensions of 15D, except for sleeping and breathing, were positively associated with MNA score. In these analyses no significant differences emerged between males and females when the results were adjusted for age and dementia.

CONCLUSIONS

Nutrition plays an important role in HRQoL among older long-term care residents.

Effect of exercise and nutritional supplementation on health-related quality of life and mood in older adults: the VIVE2 randomized controlled trial

Background

Health-related quality of life (HRQoL) and absence of depressive symptoms are of great importance for older people, which may be achieved through lifestyle interventions, e.g., exercise and nutrition interventions. The aim of this investigation was to analyze the effects of a physical activity program in combination with protein supplementation on HRQoL and depressive symptoms in community-dwelling, mobility-limited older adults.

Methods

In the Vitality, Independence, and Vigor 2 Study (VIVE2), community-dwelling men and women with an average age of 77.5 ± 5.4 years, some mobility limitations and low serum vitamin D levels (25(OH)Vit D 22.5–60 nmol/l) from two study sites (Stockholm, Sweden and Boston, USA) were randomized to receive a nutritional supplement or a placebo for 6 months. All took part in a physical activity program 2–3 times/ week. The primary outcome examined in VIVE2 was 400 M walk capacity. HRQoL was measured using the Medical Outcomes Study 36-item Short Form Health Survey (SF36), consisting of the Physical Component Summary (PCS) and Mental Component Summary (MCS), and depressive symptoms were measured using The Centre for Epidemiologic Studies Depression Scale (CES-D). In the sensitivity analyses, the sample was divided into sub-groups based on body measures and function (body mass index (BMI), appendicular lean mass index (ALMI), handgrip strength and gait speed).

Results

For the whole sample, there was a significant improvement in both MCS, mean (95% CI) 2.68 (0.5, 4.9) (p 0.02), and CES-D -2.7 (− 4.5, − 0.9) (p 0.003) during the intervention, but no difference was detected between those who received the nutritional supplement and those who received the placebo. The results revealed no significant change in PCS or variation in effects across the sub-categories.

Conclusions

This study demonstrates that a six-month intervention using a physical activity program had positive effects on mental status. No additional effects from nutritional supplementation were detected.

AdNut study: effectiveness of a high calorie and protein oral nutritional supplement with β-hydroxy-β-methylbutyrate in an older malnourished population in usual clinical practice

OBJECTIVE

To evaluate the effectiveness of a high calorie and protein, β-hydroxy-β-methylbutyrate containing oral nutritional supplement (HP-HMB-ONS), on nutritional status, activities of daily living and quality of life (QoL) in old malnourished subjects.

METHODS

We conducted an observational, prospective, open label, multicenter study. Participants were > 65 years, undernourished or at nutritional risk [Nutrition Risk Score (NRS) ≥ 3] and had been included on an ONS (HP-HMB-ONS twice daily for 12 weeks) per standard of care. Visits at baseline (V1), 6 weeks (V2) and 12 weeks (V3) were performed. The primary endpoints were gain of body weight, change in body mass index (BMI) and NRS 2002 index. Data from QoL (EQ-5D-3L) and activities of daily living (Katz index) were also collected.

RESULTS

A total of 235 participants were included in the study. Of these 148 took at least a 75% of the HP-HMB-ONS and were included in the analysis (per protocol); median age was 80.0 (SD:8.3) years, 65.5% (n = 97) were female, 67.6% (n = 100) had 2 or more diseases. At V3, a statistically significant increase in weight (2.1 kg; SD: 3.8) (p < 0.001) and BMI (0.8 kg/m2; SD: 1.45) were found compared to V1, whereas NRS 2002 values decreased by 0.9 (SD: 1.2). A significant (p < 0.001) improvement in Katz index (mean change = 0.3; SD:1.4) and EQ-5D scoring (mean change = 0.5; SD:1.9) compared to V1, were also reported.

CONCLUSIONS

The results suggest that administration of a HP-HMB-ONS improve the nutritional status and may led to a significant improvement in patients' activities of daily living and QoL, independent of baseline BMI.

Nutritional Assessment and Intervention to Prevent and Treat Malnutrition for Fall Risk Reduction in Elderly Populations

The aging US population is increasing, and it is estimated that adults older than 65 years will make up 20% of the population by 2029 and the proportion of individuals in the United States older than 65 years will outnumber individuals younger than 18 years. In older adults, accidental falls are the leading cause of fatal and nonfatal injuries. Prevalence of chronic conditions such as sarcopenia and frailty contribute to the increased risk for fall observed in this population. Nutritional status in elderly individuals is a key predictor of both frailty and sarcopenia, thus ensuring adequacy in these populations has the potential for preventing falls. Poor nutritional status is associated with the onset of frailty. Nutrition screening, assessment and interventions can be targeted at this age group to overcome treat and prevent malnutrition to minimize fall risk.

Protein Intake and Distribution in Relation to Physical Functioning and Quality of Life in Community-Dwelling Elderly People: Acknowledging the Role of Physical Activity

Increasing total protein intake and a spread protein intake distribution are potential strategies to attenuate sarcopenia related loss of physical function and quality of life. The aim of this cross-sectional study was to investigate whether protein intake and protein intake distribution are associated with muscle strength, physical function and quality of life in community-dwelling elderly people with a wide range of physical activity. Dietary and physical activity data were obtained from two studies (N = 140, age 81 ± 6, 64% male), with the following outcome measures: physical functioning (Short Physical Performance Battery (SPPB), comprising balance, gait speed and chair rise tests), handgrip strength and quality of life (EQ-5D-5L). Protein intake distribution was calculated for each participant as a coefficient of variance (CV = SD of grams of protein intake per main meal divided by the average total amount of proteins (grams) of the main meals). Based on the CV, participants were divided into tertiles and classified as spread, intermediate or pulse. The average total protein intake was 1.08 ± 0.29 g/kg/day. Total protein intake was not associated with outcome measures using multivariate regression analyses. Individuals with a spread protein diet during the main meals (CV < 0.43) had higher gait speed compared to those with an intermediate diet (CV 0.43⁻0.62) (β = -0.42, p = 0.035), whereas a spread and pulse protein diet were not associated with SPPB total score, chair rise, grip strength and Quality-Adjusted Life Year (QALY). The interaction of higher physical activity and higher total protein intake was significantly associated with higher quality of life (β = 0.71, p = 0.049). While this interaction was not associated with SPPB or grip strength, the association with quality of life emphasizes the need for a higher total protein intake together with an active lifestyle in the elderly.

Severity of pain is associated with insufficient energy coverage in hospitalised patients: A cross-sectional study

BACKGROUND & AIMS

The severity of pain is routinely assessed in hospitalised patients but the impact of pain and pain control on energy coverage has been poorly studied. This One-day cross-sectional observational study assessed the association between severity of pain and coverage of energy needs in hospitalised patients.

METHODS

Foods provided and consumed were assessed on one day by dedicated dieticians for unselected hospitalised patients receiving three meals per day. Severity of pain was evaluated by a visual analogue scale at the mealtimes, averaged over the study day, and categorized as no pain, slight, moderate or severe pain. The coverage of energy needs was expressed in percentage of predicted needs.

RESULTS

Among the 755 included patients, 63% reported having pain. Severe pain was associated with a lower energy coverage than no pain (p = 0.001) or slight pain (p = 0.001). Insufficient energy coverage, defined as ≤70% of predicted needs, occurred in 13% of the patients. In univariate logistic regressions, predictors of insufficient energy coverage were severe pain as compared to no pain (OR 2.38; 95% CI 1.21, 4.64) and treatment with opioid drugs as compared to no pain killer (OR 1.73; 95% CI 1.07, 2.79). When including sex, age, body mass index, treatment with analgesics and severity of pain in a multivariate logistic regression, severe pain more than doubled the risk of insufficient energy coverage (OR 2.32; CI 1.15, 4.66).

CONCLUSIONS

Patients experiencing severe pain have a high risk of insufficient energy coverage. Optimal pain control is probably critical to prevent underfeeding in the hospital.

Health related quality of life and its associated factors among community-dwelling older people in Sri Lanka: A cross-sectional study

BACKGROUND

Population ageing has become a public health issue as it is associated with increased morbidity, institutionalization and death. These may directly affect health-related quality of life (HRQOL) of older people.

PURPOSE

The aim of the study was to investigate HRQOL and its associated factors among community-dwelling older people in Kandy district, Sri Lanka.

METHOD

This cross-sectional survey involved 1300 older people. The Euro 5D-3L, International Physical Activity Questionnaire, body mass index, handgrip strength were used to measure HRQOL, physical activity and nutritional status of older people respectively. Factors associated with health-related quality of life were identified through complex sample logistic regression analysis.

RESULTS

Majority of older people (81.9%) reported poor health-related quality of life. Middle old (aOR: 12.06, 95% CI: 5.76, 25.23), very old (aOR: 174.74, 95% CI: 39.74, 768.38), vegetarian diets (aOR: 2.13, 95% CI: 1.14, 3.96), under-nutrition (aOR: 3.41, 95% CI: 1.65, 7.04) and over-nutrition (aOR: 1.85, 95% CI: 1.04, 3.28) were significantly associated with poor HRQOL. Using dentures (aOR: 0.05, 95% CI: 0.28, 0.90) was found as a protective factor for poor HRQOL.

CONCLUSIONS

HRQOL was poor among community-dwelling older people in Kandy district. Nutrition-related factors need to be further investigated to improve HRQOL among older people.

Selected B vitamins and their possible link to the aetiology of age-related sarcopenia: relevance of UK dietary recommendations

The possible roles of selected B vitamins in the development and progression of sarcopenia are reviewed. Age-related declines in muscle mass and function are associated with huge and increasing costs to healthcare providers. Falls and loss of mobility and independence due to declining muscle mass/function are associated with poor clinical outcomes and their prevention and management are attractive research targets. Nutritional status appears a key modifiable and affordable intervention. There is emerging evidence of sarcopenia being the result not only of diminished anabolic activity but also of declining neurological integrity in older age, which is emerging as an important aspect of the development of age-related decline in muscle mass/function. In this connection, several B vitamins can be viewed as not only cofactors in muscle synthetic processes, but also as neurotrophic agents with involvements in both bioenergetic and trophic pathways. The B vitamins thus selected are examined with respect to their relevance to multiple aspects of neuromuscular function and evidence is considered that requirements, intakes or absorption may be altered in the elderly. In addition, the evidence base for recommended intakes (UK recommended daily allowance) is examined with particular reference to original datasets and their relevance to older individuals. It is possible that inconsistencies in the literature with respect to the nutritional management of sarcopenia may, in part at least, be the result of compromised micronutrient status in some study participants. It is suggested that in order, for example, for intervention with amino acids to be successful, underlying micronutrient deficiencies must first be addressed/eliminated.

Determinants of Health Related Quality of Life in Home Dwelling Elderly Population: Appetite and Nutritional Status

OBJECTIVE

The present study aimed to examine nutritional risk factors such as poor appetite, malnutrition or obesity affecting health related quality of life in elderly.

DESIGN AND PARTICIPANTS

This is a cross-sectional population-based study consisted of 407 elderly (142 men and 265 women) mean aged 71.7±6.54 years.

MEASUREMENTS

Questionnaire including the demographic and general characteristics, health information, nutritional habits was performed by face-to-face interviews. Daily food consumption was assessed using 24-hour dietary recall. Mini Nutrition Assessment (MNA) and Mini Nutrition Assessment-Short Form (MNA-SF) were used for assessment of nutrition status. Appetite was evaluated using the Simplified Nutritional Appetite Questionnaire (SNAQ). Health related life quality scale (Short Form Health Survey -SF36) was used for evalution health related quality of life.

RESULTS

According to MNA and MNA-SF 6.1%; 4.2% of elderly people were malnutrition and 40.3%; 21.9% of them were at risk of malnutrition respectively. Accordingly, SNAQ 28.7% of elderly were risk at loss of weight. Health related quality of life scores of women were significantly lower than men. Good nutritional (MNA-SF) and good appetite (SNAQ) status, increased 1.69, 1.48 fold in the mental component summary scale scores respectively. SNAQ was the best determinant of physical component summary scale score had the greatest positive effect, good appetite status increased approximately 2.2 fold in physical scores. Polypharmacy and high BMI decreased health related quality of life in elderly.

CONCLUSION

Determinants of quality of life are preventable and treatable with early and appropriate interventions in elderly.

Selenium Concentrations and Mortality among Community-Dwelling Older Adults: Results from IlSIRENTE Study

BACKGROUND

Selenium has a wide range of pleiotropic effects, influencing redox homeostasis, thyroid hormone metabolism, and protecting from oxidative stress and inflammation. Serum selenium levels are reduced in the older population.

OBJECTIVES

to investigate the association of serum selenium levels with all-cause mortality in a sample of community-dwelling older adults.

DESIGN AND SETTING

Data are from the 'Invecchiamento e Longevità nel Sirente' (Aging and Longevity in the Sirente geographic area, ilSIRENTE) study, a prospective cohort study that collected information on individuals aged 80 years and older living in an Italian mountain community (n=347). The main outcome was risk of death after ten years of follow-up.

PARTICIPANTS AND MEASUREMENTS

Participants were classified according to the median value of selenium (105.3 μg/L) in two groups: high selenium and low selenium.

RESULTS

A total of 248 deaths occurred during a 10-year follow-up. In the unadjusted model, low levels of selenium was associated with increased mortality (HR, 0.66; 95% CI 0.51-0.85). After adjusting for potential confounders the relationship remained significant (HR, 0.71; 95% CI 0.54-0.92).

CONCLUSIONS

Low serum levels of selenium are associated with reduced survival in elderly, independently of age and other clinical and functional variables.

Socioeconomic Position and Malnutrition among Older Adults: Results from the FRADEA Study

OBJECTIVES

Low socioeconomic position (SEP) is related to many health-related conditions in older adults. However, there is a lack of knowledge on the association between SEP and malnutrition, a condition with serious consequences for older people in terms of quality of life and adverse health events. In the current study, we investigated socioeconomic inequalities in malnutrition and sub-domains of malnutrition in a sample of Spanish older adults.

DESIGN

Cross-sectional population-based study.

SETTING

Urban area of Albacete, Spain.

PARTICIPANTS

836 participants over age 70 from the first measurement wave (2007-2009) of the Frailty and Dependence in Albacete (FRADEA) study, a population-based cohort study.

MEASUREMENTS

Educational level and occupational level were the indicators of SEP. Nutritional risk was measured with the Mini Nutrition Assessment® Short Form (MNA®-SF). Logistic regression analyses were performed.

RESULTS

For both socioeconomic indicators there was a statistically significant association with nutritional risk (OR low education=1.99, 95% CI=1.18-3.35; OR low occupational level=1.71, 95% CI=1.08-2.72). However, these associations disappeared after adjusting for age and sex (OR low education=1.51, 95% CI=0.88-2.60 ; OR low occupational level=1.32, 95% CI=0.80-2.17). In adjusted models, statistically significant associations between SEP and sub-domains of the MNA®-SF were observed, but these associations were not consistent across socioeconomic indicators.

CONCLUSIONS

This study found that malnutrition is a condition that can appear in any older adult, regardless of their socioeconomic group. These findings suggest that interventions to prevent malnutrition in older adults can be targeted at a general older population, and do not have to be SEP specific.

Quality of life and risk of malnutrition in a home-dwelling population over 75 years old

OBJECTIVES

To evaluate the quality of life of a noninstitutionalized population aged older than 75 y by determining nutritional and health status, and to investigate the relationship between nutritional risk and quality of life.

METHODS

A cross-sectional study of elderly people was conducted in Garrucha (Almería) in southern Spain. A total of 102 participants (61 women and 41 men) aged older than 75 y. The Mini Nutritional Assessment test was used to detect nutritional risk. Quality of life was assessed using the EuroQol-5D test. Body mass index, education level, physical activity, history of illness, use of medication, and smoking and alcoholic habits were also determined.

RESULTS

Most of the population presented an acceptable nutritional status, were functionally independent and presented a best health state evaluated by the EuroQol-5D index. However, almost 20.6% were at risk of malnutrition, especially women and participants over the age of 90 y. A significant negative association (P < 0.05) between the risk of malnutrition and index of quality of life was found.

CONCLUSIONS

Risk of malnutrition was common among community-dwelling older people. Participants who were malnourished or at high risk of malnutrition also had a lower rate of quality of life and greater loss of personal autonomy.

The impact of health literacy and life style risk factors on health-related quality of life of Australian patients

BACKGROUND

Limited evidence exists regarding the relationship between health literacy and health-related quality of life (HRQoL) in Australian patients from primary care. The objective of this study was to investigate the impact of health literacy on HRQoL in a large sample of patients without known vascular disease or diabetes and to examine whether the difference in HRQoL between low and high health literacy groups was clinically significant.

METHODS

This was a cross-sectional study of baseline data from a cluster randomised trial. The study included 739 patients from 30 general practices across four Australian states conducted in 2012 and 2013 using the standard Short Form Health Survey (SF-12) version 2. SF-12 physical component score (PCS-12) and mental component score (MCS-12) are derived using the standard US algorithm. Health literacy was measured using the Health Literacy Management Scale (HeLMS). Multilevel regression analysis (patients at level 1 and general practices at level 2) was applied to relate PCS-12 and MCS-12 to patient reported life style risk behaviours including health literacy and demographic factors.

RESULTS

Low health literacy patients were more likely to be smokers (12 % vs 6 %, P = 0.005), do insufficient physical activity (63 % vs 47 %, P < 0.001), be overweight (68 % vs 52 %, P < 0.001), and have lower physical health and lower mental health with large clinically significant effect sizes of 0.56 (B (regression coefficient) = -5.4, P < 0.001) and 0.78(B = -6.4, P < 0.001) respectively after adjustment for confounding factors. Patients with insufficient physical activity were likely to have a lower physical health score (effect size = 0.42, B = -3.1, P < 0.001) and lower mental health (effect size = 0.37, B = -2.6, P < 0.001). Being overweight tended to be related to a lower PCS-12 (effect size = 0.41, B = -1.8, P < 0.05). Less well-educated, unemployed and smoking patients with low health literacy reported worse physical health. Health literacy accounted for 45 and 70 % of the total between patient variance explained in PCS-12 and MCS-12 respectively.

CONCLUSIONS

Addressing health literacy related barriers to preventive care may help reduce some of the disparities in HRQoL. Recognising and tailoring health related communication to those with low health literacy may improve health outcomes including HRQoL in general practice.

Are plasma mineral levels related to antibody response to influenza vaccination in older adults?

INTRODUCTION

An effective immune response to vaccination may be related to nutritional status. This study examined the association of plasma mineral levels with hemagglutination inhibition (HI) titers produced in response to influenza vaccine in older adults.

METHODS

Prior to (Day 0) and 21 (range = 19-28) days after receiving the 2013-14 influenza vaccine, 109 adults ages 51-81 years, provided blood samples. Serum samples were tested for HI activity against the A/H1N1 and A/H3N2 2013-2014 vaccine virus strains. Plasma minerals were collected in zinc-free tubes and assayed by inductively coupled plasma mass spectrometry. HI titers were reported as seroprotection (≥1:40) and seroconversion (≥ 4-fold rise from Day 0 (minimum HI = 1:10) to Day 21). Both HI titers and mineral values were skewed and thus log2 transformed. Magnesium (Mg), phosphorus (P), zinc (Zn), copper (Cu), iron (Fe), potassium (K) and the Cu to Zn ratio were tested. Logistic regression analyses were used to determine the associations between mineral levels and seroconversion and seroprotection of HI titers for each influenza A strain.

RESULTS

Participants were 61% white, 28% male, 39% diabetic, and 81% overweight/obese with a mean age of 62.6 y. In logistic regression, Day 21 A/H1N1 seroprotection was associated with P and Zn at Day 21(P < 0.05). Seroconversion of A/H1N1 was associated with Day 21 Cu, P, and Mg (P < 0.03). Day 21 A/H3N2 seroprotection and seroconversion were associated with Day 21 P (P < 0.05).

CONCLUSIONS

Phosphorus was associated with seroprotection and seroconversion to influenza A after vaccination; these associations warrant additional studies with larger, more diverse population groups.

Prevalence and Association of Undernutrition with Quality of Life among Swedish People Aged 60 Years and Above: Results of the SNAC-B Study

OBJECTIVES

This study aimed to assess the prevalence of undernutrition among elderly and to investigate the association of risk of undernutrition with health-related quality of life and life satisfaction controlling for age, gender, marital status, economic status, housing arrangement, education level, functional ability, and diseases.

DESIGN

A cross-sectional study design was used for this study. The baseline data (2001-2003) of "The Swedish National Study of Aging and Care-Blekinge (SNAC-B)" was used.

SETTING

This population-based study focused on both home-living and special-housing residents.

PARTICIPANTS

The participants (n=1402) were randomly selected and included both males and females 60-96 years of age residing in a municipality of south-east Sweden.

MEASUREMENTS

The risk of undernutrition was estimated by the occurrence of at least one anthropometric measure (body mass index, mid-arm circumference, and calf circumference) below cut-off, in addition to the presence of at least one subjective measure (declined food intake, weight loss, and eating difficulty). The dependent variables, health-related quality of life and life satisfaction, were measured by the validated short form health survey (SF-12) and Liang's life satisfactions index A (LSIA), respectively.

RESULTS

According to the criterion, 8.5% of the participants were at risk of undernutrition, and subjects at nutritional risk were significantly older, female, unmarried/widowed/divorced, residing in special housing, and functionally impaired. The risk of undernutrition was significantly associated with poor health-related quality of life, both in the physical (OR 2.31, 95% CI 1.18-4.52) and mental (OR 2.34, 95% CI 1.22-4.47) dimensions. However, no significant association was observed between nutritional status and life satisfaction (OR 1.30, 95% CI 0.70-2.40).

CONCLUSION

The risk of undernutrition significantly increases the risk of poor physical and mental health-related quality of life but has negligible impact on life satisfaction. This study also highlights the importance of functional ability both for the prevention of undernutrition and promotion of quality of life. However, more studies are needed to validate the tool used here for undernutrition risk assessment before it can be used in clinical or population settings.

Nutritional Guidance Improves Nutrient Intake and Quality of Life, and May Prevent Falls in Aged Persons with Alzheimer Disease Living with a Spouse (NuAD Trial)

OBJECTIVE

The aim was to examine the effect of tailored nutritional guidance on nutrition, health-related quality of life (HRQoL) and falls in persons with Alzheimer disease (AD).

DESIGN

Randomised controlled trial.

SETTING AND PARTICIPANTS

Persons with AD living with a spouse.

INTERVENTION

Tailored nutritional guidance with home visits during one year. The control group received a written guide about nutrition in older adults and all community-provided normal care.

MEASUREMENTS

The primary outcome measure was weight change, and secondary outcomes included changes in protein and micronutrient intakes from three-day food records, HRQoL (15D) and rate of falls.

RESULTS

Of the participants (n = 78) with AD (mean age 77.4, 69% males), 40% were at risk for malnutrition, 77% received < 1.2 g/bodyweight (kg) of protein at baseline. We found no difference in weight change between the groups. At 12 months, the mean change in protein intake was 0.05 g/bodyweight (kg) (95% CI -0.06 to 0.15) in the intervention group (IG), and -0.06 g/kg (95% CI -0.12 to 0.02) in the control group (CG) (p = 0.031, adjusted for baseline value, age, sex, MMSE and BMI). Participants' HRQoL improved by 0.006 (95% CI -0.016 to 0.028) in the IG, but declined by -0.036 (95% CI -0.059 to 0.013) in the CG (p = 0.007, adjusted for baseline value, age, sex, MMSE and BMI). Dimensions that differed included mental functioning, breathing, usual activities and depression. The fall rate was 0.55 falls/person per year (95% CI 0.34 to 0.83) in the IG, and 1.39 falls/person per year (95% CI 1.04 to 1.82) in the CG (IRR 0.55; 95% CI 2.16 to 6.46; p < 0.001 adjusted for age, sex and MMSE).

CONCLUSIONS

Tailored nutritional guidance improves nutrition and HRQoL, and may prevent falls among AD people living with a spouse.

Improved Health-Related Quality of Life, and More Days out of Hospital with Supplementation with Selenium and Coenzyme Q10 Combined. Results from a Double Blind, Placebo-Controlled Prospective Study

BACKGROUND

The impact of supplementation with selenium and coenzyme Q10 (CoQ10) on health-care usage and health-related quality of life (Hr-QoL) in community-dwelling elderly people has, to our knowledge, not previously been investigated.

AIM

To investigate the effect of 48 months supplementation with CoQ10 and selenium on community-dwelling elderly as regards: (I) the number of days out of hospital, and (II) the effect on Hr-QoL.

METHODS

A 48-month double-blind randomized placebo-controlled trial was carried out. A total of 443 participants were given CoQ10 and organic selenium yeast combined, or a placebo. All admissions to the Department of Internal Medicine or Cardiology were evaluated. Hr-QoL were measured with the Short Form-36 (SF-36), the Cardiac Health Profile (CHP) and one item overall-quality of life (overall-QoL).

RESULTS

A total of 206 participants were evaluated after 48 months. No changes were found in the number of days out of hospital or Hr-QoL. A sub-analysis of participants matched for age, gender and baseline cardiac wall tension as measured by NT-proBNP was performed. The mean number of days out of hospital was 1779 for those taking the active substance compared to 1533 for those taking the placebo (p=0.03). Those with active substance declined significantly less in the HR-QoL domains of physical role performance (p=0.001), vitality (p=0.001), physical component score (p=0.001), overall QoL (p=0.001), somatic dimension (p=0.001), conative dimension (p=0.001) and global function (p=0.001).

CONCLUSION

In a match-group analysis selenium and CoQ10 increased the number of days out of hospital and slowed the deterioration in Hr-QoL.

Association between serum vitamin D status and health-related quality of life (HRQOL) in an older Korean population with radiographic knee osteoarthritis: data from the Korean national health and nutrition examination survey (2010-2011)

Background

Vitamin D is important in bone health and its relationship with osteoarthritis has recently been reported. Both vitamin D deficiency and knee osteoarthritis are age dependent and are known to affect quality of life (QOL) in older populations. In this study, we aimed to determine the association between vitamin D status and health-related quality of life (HRQOL) in an older Korean population with knee osteoarthritis.

Methods

A total of 2,165 participants aged ≥50 years with radiographic knee osteoarthritis defined as Kellgren-Lawrence (KL) grade ≥2 were selected from data from the 5th Korean National Health and Nutrition Examination Survey (KNHANES V), a representative cross-sectional nationwide survey conducted in 2010–2011. They stratified into two levels by vitamin D status (deficiency <10 ng/dL and normal ≥10 ng/dL). HRQOL was measured using the EuroQOL visual analogue scale (EQ-VAS) and the five dimensions and summary index of the EuroQOL-5 dimension (EQ-5D).

Results

The vitamin D deficiency group was more likely to report problems with mobility, self-care, and usual activities. Vitamin D deficiency was significantly associated with poor HRQOL indicated by the lowest quartile of EQ-VAS (unadjusted odds ratio [OR] =1.832, p = 0.006) and the lowest quartile of the EQ-5D index (unadjusted OR = 1.992, p = 0.003). Theses associations of vitamin D status with EQ-VAS and EQ-5D index were maintained after adjustment for age and sex (Model 1: OR = 1.677, p = 0.022 and OR = 1.701, p = 0.021, respectively). The significant associations of vitamin D status with EQ-VAS were maintained after adjustment for other possible covariates (Model 3: OR = 1.562, p = 0.044). Also, a trend of associations between vitamin D status and EQ-5D index were shown after adjustment for other covariates (Model3: OR = 1.681, p = 0.056).

Conclusion

This is the first study to reveal that vitamin D status is independently associated with HRQOL in an older Korean population with knee osteoarthritis. Our results suggest that the maintenance of sufficient vitamin D status may be important to prevent QOL decline in older populations with knee osteoarthritis.

Dietary management of IBD--insights and advice

The current general interest in the use of food choice or diet in maintaining good health and in preventing and treating disease also applies to patients with IBD, who often follow poor or nutritionally challenging dietary plans. Unfortunately, dietary advice plays only a minor part in published guidelines for management of IBD, which sends a message that diet is not of great importance. However, a considerable evidence base supports a focused and serious attention to nutrition and diet in patients with IBD. In this Review, a step-wise approach in the evaluation and management of these patients is proposed. First, dietary intake and eating habits as well as current nutritional state should be documented, and corrective measures instituted. Secondly, dietary strategies as primary or adjunctive therapy for the reduction of inflammation and/or prevention of relapse of IBD should be seriously contemplated. Thirdly, use of diet to improve symptoms or lessen the effects of complications should be considered. Finally, dietary advice regarding disease prevention should be discussed when relevant. An increasing need exists for applying improved methodologies into establishing the value of current and new ways of using food choice as a therapeutic and preventive tool in IBD.

A review of dietary selenium intake and selenium status in Europe and the Middle East

This is a systematic review of existing data on dietary selenium (Se) intake and status for various population groups in Europe (including the United Kingdom (UK)) and the Middle East. It includes English language systematic reviews, meta-analyses, randomised controlled trials, cohort studies, cross-sectional and case-control studies obtained through PUBMED searches from January, 2002, to November, 2014, for European data and from 1990 to November 2014, for Middle Eastern data. Reports were selected if they included data on Se intake and status. The search identified 19 European/UK studies and 15 investigations in the Middle East that reported Se intake and Se concentration in water and/or food and 48 European/UK studies and 44 investigations in the Middle East reporting Se status. Suboptimal Se status was reported to be widespread throughout Europe, the UK and the Middle East, and these results agreed with previous reports highlighting the problem. Eastern European countries had lower Se intake than Western European countries. Middle Eastern studies provided varying results, possibly due to varying food habits and imports in different regions and within differing socioeconomic groups. In conclusion, Se intake and status is suboptimal in European and Middle Eastern countries, with less consistency in the Middle East.
