Health determinants of nutritional status in community-dwelling older population: the VERISAÚDE study

Identifying Malnutrition Risk in the Elderly: A Single- and Multi-Parameter Approach

Malnutrition is a significant concern affecting the elderly, necessitating a complex assessment. This study aims to deepen the understanding of factors associated with the assessment of malnutrition in the elderly by comparing single- and multi-parameter approaches. In this cross-sectional study, 154 individuals underwent a comprehensive geriatric assessment (CGA). Malnutrition risk was determined using the mini nutritional assessment (MNA). Additional factors assessed included sarcopenia, polypharmacy, depression, appetite, handgrip strength, and gait speed. Phase angle (PA) and body composition were measured using bioelectrical impedance analysis (BIA). The MNA identified a malnutrition risk in 36.8% of individuals. The geriatric depression scale (GDS) and PA demonstrated moderate effectiveness in assessing malnutrition risk, with AUC values of 0.69 (95% CI: 0.60-0.78) and 0.62 (95% CI: 0.54-0.72), respectively. A logistic regression model incorporating handgrip strength, skeletal muscle mass, sarcopenia, osteoporosis, depression, specific antidepressant use, mobility, appetite, and smoking achieved superior performance in predicting malnutrition risk, with an AUC of 0.84 (95% CI: 0.77-0.91). In conclusion, this study demonstrates that integrating multiple parameters into a composite model provides a more accurate and comprehensive assessment of malnutrition risk in elderly adults.

Association between malnutrition and cognitive frailty in older adults: A systematic review and meta-analysis

BACKGROUND

To systematically assess the association between cognitive frailty (CF) and malnutrition in older adults.

METHODS

8 databases were retrieved up until April 2023 by two reviewers in dependently, and meta-analysis was performed by Stata 16.0 software.

RESULTS

A total of 19 studies were meta-analyzed to assess the relationship between CF and malnutrition in older adults. The pooled prevalence of CF from 17 studies was 23 %, and the pooled prevalence of malnutrition among patients with CF from 12 studies was 57 %. Data from 13 studies on the association between CF and malnutrition unveiled a high risk of CF in older adults with malnutrition (OR = 3.77, 95 % CI: 2.49-5.69).

CONCLUSION

The prevalence of malnutrition is high in older adults with CF, and there is a significant delve into targeted treatment and preventive measures to ameliorate the quality of life of older adults.

Nutritional risk and adverse health outcomes in Chinese community-dwelling older adults: A study based on the Elderly Nutritional Indicators for Geriatric Malnutrition Assessment (ENIGMA)

OBJECTIVES

Malnutrition and nutritional risk are risk factors for many adverse health outcomes in older adults, but they have rarely been assessed in China. The aim of this study was to evaluate the availability of Elderly Nutritional Indicators for Geriatric Malnutrition Assessment (ENIGMA), a nutritional scale originally developed to predict mortality, in assessing nutritional risks and predicting adverse health outcomes in Chinese community-dwelling older adults.

METHODS

This was a population-based longitudinal cohort study (Chinese Longitudinal Healthy Longevity Survey), with a 4-y follow-up of 2063 community-dwelling adults aged 65 y or older. Nutritional risks were assessed via the use of ENIGMA and Geriatric Nutritional Risk Index (GNRI) at baseline (the 2014 wave). Cognitive impairment, functional limitation, and frailty were evaluated using the Chinese version of the Mini-Mental State Examination, Instrumental Activities of Daily Living/Instrumental Activities of Daily Living scale, and Frailty Index, respectively, at baseline and 4-y follow-up (the 2018 wave). Mortality was measured by survival status and duration of exposure to death from baseline to follow-up. The associations of nutritional risks with prevalent/incident cognitive impairment, functional limitation and frailty, and 4-y mortality were estimated using logistic regression and Cox proportional hazards regression models, adjusting for confounders. The discriminatory accuracy of ENIGMA and GNRI for these adverse health outcomes were compared by receiver operating characteristic analyses.

RESULTS

According to ENIGMA, 48.6% of the Chinese community-dwelling older adults (age: 86.5±11.3 y) showed moderate and high nutritional risk. Nutritional risks defined by the ENIGMA were significantly associated with increased prevalence and incidence of cognitive impairment, functional limitation, and frailty (odds ratio ranging from 1.79 to 89.6, values ranging from P < 0.001 to 0.048) but were mostly insignificant for that defined by GNRI. With respect to 4-y mortality, nutritional risks as defined by GNRI showed better prediction effects than those defined by ENIGMA. Receiver operating characteristic analyses indicated that nutritional risks defined by ENIGMA had better discriminatory accuracy than those defined by GNRI for prevalent and incident cognitive impairment (C = 0.73 vs 0.64, P < 0.001; C = 0.65 vs 0.59, P = 0.015, respectively), functional limitation (C = 0.74 vs 0.63, P < 0.001 at baseline; C = 0.61 vs 0.56, P = 0.016 at follow-up), frailty (C = 0.85 vs 0.67, P < 0.001 at baseline; C = 0.64 vs 0.55, P < 0.001 at follow-up), and even 4-y mortality (C = 0.68 vs 0.64, P = 0.020).

CONCLUSIONS

ENIGMA could serve as a nutritional risk screening tool that has a robust role in predicting cognitive impairment, functional limitation, and frailty in Chinese community-dwelling older adults. It may be recommended for early nutritional risk screening and has the potential to guide early nutritional intervention in communities and primary care settings in China.

Malnutrition and Polypharmacy in Older Adult Patients Receiving Home Care Nursing Services: A Cross-sectional Study

OBJECTIVE

We studied the nutritional status of older adult adults receiving home nursing care using demographic data, household category, polypharmacy, and potentially inappropriate medications (PIMs).

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

Two Norwegian municipalities during 2017-2019; home nursing service clients aged ≥70 years.

METHODS

Inclusion of patients and data collection were done by nurses working in the home services. Recorded data were participants' age, sex, living alone or with others, nutritional status (Mini Nutritional Assessment-Short Form and body mass index), regular prescription drugs, and potentially inappropriate medications (PIMs) according to the Norwegian General Practice Nursing home (NORGEP-NH) criteria. Descriptive statistics and logistic regression were used.

RESULTS

Of the 270 patients (mean age 84.2 years; 64.8% females; 188 living alone), 25 (9.3%) were malnourished and 154 (57%) at risk of malnutrition; in addition, 14.8% had a BMI <21 and 27.8% had lost weight in the previous 3 months. The odds for being at malnutrition risk was higher if living with others vs living alone: adjusted odds ratio (OR) 2.23 (1.20-4.13). Female sex, older age, and better mobility was associated with living alone. The mean number of regular drugs was 7.3. Overall, 43.3% of the participants used at least 1 PIM. Using 0 to 5 drugs vs ≥6 drugs (polypharmacy) was associated with higher odds for malnutrition risk: adjusted OR 1.97 (1.04-3.75). Compared with well-nourished patients, those at risk for or who were malnourished used fewer cardiovascular and musculoskeletal drugs. Exposure to PIMs was not associated with nutritional status.

CONCLUSIONS AND IMPLICATIONS

Two-thirds of home nurse clients were either malnourished or at risk for malnutrition. Living with others or using fewer daily drugs implied increased risk for malnourishment, probably reflecting differences in morbidity and possible inappropriateness of medication use. Future research on nutritional status and medication use should aim for including more clinical data than simple drug counts.

Prevalence of Co-Occurrence of Physical Frailty and Malnutrition and Its Associated Factors Among Community-Dwelling Older Adults in a Rural District, Malaysia

Frailty and malnutrition commonly co-occur but remains undetected and untreated in community settings. This study aimed to determine the prevalence of co-occurring frailty and malnutrition, and its associated factors among community-dwelling older adults in a rural setting in Malaysia. A cross-sectional study was conducted among adults aged ≥ 60 residing in Kuala Pilah district, Negeri Sembilan, Malaysia. Physical frailty and nutritional status were assessed using the Fried phenotype and the Mini Nutritional Assessment (MNA), respectively. Among 1855 participants, 6.4% had co-occurring frailty and at-risk/malnutrition and 11.3% had co-occurring prefrailty and at-risk/malnutrition. Older age, fair-to-poor self-rated health, long-term disease, polypharmacy, activities of daily living (ADLs) and instrumental ADLs' disabilities, cognitive impairment, and poor social support were associated with higher odds of co-occurring frailty and malnutrition. Therefore, beside early identification, targeted intervention is crucial to prevent or delay the progression of frailty and malnutrition in this population.

Quality of life and socio-demographic factors associated with nutritional risk in Brazilian community-dwelling individuals aged 80 and over: cluster analysis and ensemble methods

Introduction

The aim of the present study was to use cluster analysis and ensemble methods to evaluate the association between quality of life, socio-demographic factors to predict nutritional risk in community-dwelling Brazilians aged 80 and over.

Methods

This cross-sectional study included 104 individuals, both sexes, from different community locations. Firstly, the participants answered the sociodemographic questionnaire, and were sampled for anthropometric data. Subsequently, the Mini-Mental State Examination (MMSE) was applied, and Mini Nutritional Assessment Questionnaire (MAN) was used to evaluate their nutritional status. Finally, quality of life (QoL) was assessed by a brief version of World Health Organizations' Quality of Life (WHOQOL-BREF) questionnaire and its older adults' version (WHOQOL-OLD).

Results

The K-means algorithm was used to identify clusters of individuals regarding quality-of-life characteristics. In addition, Random Forest (RF) and eXtreme Gradient Boosting (XGBoost) algorithms were used to predict nutritional risk. Four major clusters were derived. Although there was a higher proportion of individuals aged 80 and over with nutritional risk in cluster 2 and a lower proportion in cluster 3, there was no statistically significant association. Cluster 1 showed the highest scores for psychological, social, and environmental domains, while cluster 4 exhibited the worst scores for the social and environmental domains of WHOQOL-BREF and for autonomy, past, present, and future activities, and intimacy of WHOQOL-OLD.

Conclusion

Handgrip, household income, and MMSE were the most important predictors of nutritional. On the other hand, sex, self-reported health, and number of teeth showed the lowest levels of influence in the construction of models to evaluate nutritional risk. Taken together, there was no association between clusters based on quality-of-life domains and nutritional risk, however, predictive models can be used as a complementary tool to evaluate nutritional risk in individuals aged 80 and over.

The risk of malnutrition and its clinical implications in older patients with cancer

AIM

Malnutrition is a common geriatric syndrome with multiple negative outcomes including mortality. However, there is a scarcity of literature that focuses on the relationship between malnutrition risk and its clinical implications on geriatric syndromes and mortality among cancer patients. The aim of this study is to determine the clinical importance of malnutrition risk in geriatric oncology practice.

METHOD

180 patients with cancer who were ≥ 65 years were included in the study. All patients were questioned in terms of geriatric syndromes, including polypharmacy, frailty, probable sarcopenia, fall risk, dynapenia, depression, cognitive impairment, insomnia, and excessive daytime sleepiness. Mini Nutritional Assessment scores > 23.5 and 17-23.5 were categorized as well-nourished and malnutrition risk, respectively.

RESULTS

Of the 180 patients (mean age 73.0 ± 5.6 years, female: 50%), the prevalence of malnutrition risk was 28.9%. There was no statistically significant difference between the groups in terms of age, gender, education, marital status, body mass index, and comorbidities except for chronic obstructive pulmonary disease (p > 0.05). After adjustment for age, sex, and body mass index; polypharmacy (odds ratio [OR]: 3.17; 95% confidence interval [CI], 1.48-6.81), reduced calf circumference (OR: 3.72; 95% CI, 1.22-11.38), fall risk (OR: 2.72; 95% CI, 1.03-7.23), depression (OR: 6.24; 95% CI, 2.75-14.18), insomnia (OR: 4.89; 95% CI, 2.16-11.05), and frailty (OR: 2.44; 95% CI, 1.75-3.40) were associated with malnutrition risk compared to well-nourished patients (p < 0.05). Median survival in patients with malnutrition risk was 21.3 months (range 14.1-28.4 95% CI) and median survival in patients who were defined as well nourished was not reached (p < 0.001).

CONCLUSION

The risk of malnutrition was associated with a higher risk for all-cause mortality in older patients with cancer, and was associated with many geriatric syndromes, including polypharmacy, fall risk, frailty, insomnia, and depression.

Attention, Praxis, and Reasoning Are Associated with Risk of Undernutrition in Older People with Cognitive Impairment

BACKGROUND

Dementia is a risk factor for undernutrition. However, it is not clear if specific cognitive deficits have a higher risk of undernutrition and how much appetite/nutritional problems and caregiver stress mediate this association.

OBJECTIVE

To evaluate the relationship between nutritional status and severity of global and function-specific scores of cognitive dysfunctions, and to which extent this association is mediated by appetite/nutritional problems and caregiver stress.

METHODS

Cross-sectional analysis of the ReGAl study data, including 761 older adults attending a Memory Clinic. Nutritional status was evaluated with Mini Nutritional Assessment (MNA). The relationship between scores at neuro-cognitive tests and risk of undernutrition was evaluated using logistic regression models adjusted for potential confounders. To allow comparison between different tests, all scores were standardized. Mediation analysis was used to evaluate how much appetite/nutritional problems and caregiver stress mediate this association.

RESULTS

Mean age was 77 years (SD: 9), 37.3% were women. Exploring different cognitive domains, a stronger association was documented for attentive matrices (OR:0.49, 95% CI: 0.34-0.72), the figure copy test (OR:0.63, 95% CI: 0.45-0.88), and the verbal judgement test (OR:0.61, 95% CI: 0.42-0.91). The proportion of the effect of cognition (MMSE) on nutritional status mediated by caregiver distress was 9.5% (95% CI: 0.002-0.27), the proportion mediated by appetite/nutritional problems was 11% (95% CI: -4.8-3.18).

CONCLUSION

Risk of undernutrition is associated to cognitive decline; a stronger association was observed for attention, praxis, and reasoning. Caregiver distress is a mediator of this association. This information should be considered in the management plans of this population.

Undernutrition and associated factors among elderly people served in Public Servants Social Security Agency in Harar, Eastern Ethiopia

Objective:

Undernutrition in the elderly has adverse effects on physiological functions and various clinical outcomes. In Ethiopia, similar to many developing countries, there is a dearth of epidemiological data on the nutritional status of the elderly. This study aimed to assess the magnitude of undernutrition and associated factors among the elderly population enrolled in the Public Servants Social Security Agency in Harar, eastern Ethiopia.

Method:

A cross-sectional study was carried out among 337 elderly adults from June to August 2020. The Mini Nutritional Assessment Tool Short Form assessed the nutritional status of the elderly. Data were entered in Epi Data software version 3.1 and transferred to SPSS version 20 for analysis. Ordinal logistic regression assessed factors associated with undernutrition, using variables with a p value less than 0.05 as statistically significant.

Result:

The magnitude of undernutrition was 16.6% and 45.1% were at risk of undernutrition. Being unable to read and write (odds ratio (OR) = 3.64; 95% confidence interval (CI), 1.98–6.72), elderly with morbidities (OR = 2.05; 95% CI, 1.15–3.64), low dietary diversity score (OR = 3.52; 95% CI, 1.63–7.60), and elderly who were food insecure (OR = 0.59; 95% CI, 0.37–0.95) were significantly associated with undernutrition.

Conclusion:

The magnitude of undernutrition among the elderly is a public health issue. Independent predictors include educational status, morbidity, dietary diversity, and food insecurity. Intervention programs need to focus on the elderly’s nutrition, access to healthy foods, and other health issues.

Differentiation of the Nutritional Risk of Polish Elderly People According to Selected Demographic Characteristics and Declared Socioeconomic Status

Nutritional risk screening in older people can help to not only identify health risks but also to treat them effectively. The aim of this work was to assess the relationship between the demographic characteristics (age, gender and place of residence) and socioeconomic status of older people in the community and nutritional risk. The Seniors in the Community: Risk Evaluation for Eating and Nutrition (SCREEN-14) questionnaire was used to evaluate the nutritional risk. The study was conducted in 417 people (312 women and 105 men) between 60 and 95 years old (70.8 ± 6.73 years). Multivariate correspondence analysis (MCA) was used to determine the relationships between the categories of variables describing the level of nutritional risk, demographic characteristics and the value of the socioeconomic status (SES) index. To assess the relationship between identified nutritional risks, demographics and SES index variables, we used logistic regression analysis. Based on these studies, nutritional risk factors for older people in Poland were identified. It has been shown that larger cities and low socioeconomic status are closely linked to higher nutritional risk. At the same time, age and gender were not significant factors influencing nutritional risk. Identifying the factors that increase the nutritional risk of older people can help to improve their quality of life.

Ageing rate of older adults affects the factors associated with, and the determinants of malnutrition in the community: a systematic review and narrative synthesis

BACKGROUND

Malnutrition negatively impacts on health, quality of life and disease outcomes in older adults. The reported factors associated with, and determinants of malnutrition, are inconsistent between studies. These factors may vary according to differences in rate of ageing. This review critically examines the evidence for the most frequently reported sociodemographic factors and determinants of malnutrition and identifies differences according to rates of ageing.

METHODS

A systematic search of the PubMed Central and Embase databases was conducted in April 2019 to identify papers on ageing and poor nutritional status. Numerous factors were identified, including factors from demographic, food intake, lifestyle, social, physical functioning, psychological and disease-related domains. Where possible, community-dwelling populations assessed within the included studies (N = 68) were categorised according to their ageing rate: 'successful', 'usual' or 'accelerated'.

RESULTS

Low education level and unmarried status appear to be more frequently associated with malnutrition within the successful ageing category. Indicators of declining mobility and function are associated with malnutrition and increase in severity across the ageing categories. Falls and hospitalisation are associated with malnutrition irrespective of rate of ageing. Factors associated with malnutrition from the food intake, social and disease-related domains increase in severity in the accelerated ageing category. Having a cognitive impairment appears to be a determinant of malnutrition in successfully ageing populations whilst dementia is reported to be associated with malnutrition within usual and accelerated ageing populations.

CONCLUSIONS

This review summarises the factors associated with malnutrition and malnutrition risk reported in community-dwelling older adults focusing on differences identified according to rate of ageing. As the rate of ageing speeds up, an increasing number of factors are reported within the food intake, social and disease-related domains; these factors increase in severity in the accelerated ageing category. Knowledge of the specific factors and determinants associated with malnutrition according to older adults' ageing rate could contribute to the identification and prevention of malnutrition. As most studies included in this review were cross-sectional, longitudinal studies and meta-analyses comprehensively assessing potential contributory factors are required to establish the true determinants of malnutrition.

Quality of Life and Nutritional Status of the Geriatric Population of the South-Central Part of Nepal

Background

The main objective of the study was to assess the nutritional status and quality of life in the geriatric population of Lahan municipality of Siraha district.

Methods

A cross-sectional analytical study was conducted in Lahan municipality of Siraha district from June to December 2017. The Mini-Nutritional Assessment tool was used to investigate the nutritional status, and World Health Organization Quality of Life-OLD questionnaires were used to assess the quality of life among geriatric population.

Result

Out of the total participants, one-third (45.7%) of the participants were at risk of malnutrition and 19.8% were malnourished while 34.5% had normal nutritional status. It was seen that 48.2% of participants had good quality of life whereas 51.8% of them had poor quality of life. There was a significant association between nutritional status and quality of life in the elderly population.

Conclusion

The findings showed the need for active ageing interventions to improve the nutritional status and quality of life of elders at the community settings. Proper attention should be focused on elders' nutrition to reduce the observed prevalence of malnutrition, and focus should be given on the nutrition status that leads to improve the quality of life of elders.

[Risk factors associated with malnutrition of community-dwelling older adults: A rapid review]

The aim of this review was to determine the most important risk factors (RF) in the development of malnutrition in people over 65 years living in the community. A rapid review has been conducted by applying the PRISMA methodology (Preferred Reporting Items of Systematic Reviews and Meta-Analyses) and using the Medline database (PubMed). A search strategy was drawn up, up to 13 January 2020. A total of 24 articles published in the last 5years were included in this review. Assuming the methodological limitations of the present review, it is possible to conclude that undernutrition is a multifactorial problem whose most significant RF are: age, economic status, alterations in the digestive system, comorbidity, polymedication, dependence on the performance of daily life activities, physical inactivity, food insecurity, depression, social isolation, and the field of self-perceptions. Early identification of geriatric patients exposed to these RF can allow a preventive approach in the development of malnutrition from primary care.

Malnutrition among community dwelling older adults in a rural block area of South India

Background:

Kerala state has highest proportion of older adults in India. There is paucity of information on burden of malnutrition (under-nutrition) among them in the state. This study aimed to measure prevalence and associated factors of malnutrition among older adults in a rural community of Kerala.

Methods:

A community based cross-sectional study was conducted in 2018, among randomly selected 245 older persons (age ≥ 60 years) across rural area of Nemom block panchayath in Thiruvananthapuram district of Kerala. Nutritional status was determined by Mini Nutritional Assessment tool. Other components of the interviewer-administered questionnaire were Barthel Index, Geriatric Depression Scale-15, socio-demography, morbidity and substance abuse details. Chi Square test and binary logistic regression were done appropriately.

Results:

Prevalence of malnutrition was 14.3% (95% CI – 9.9% to 18.7%) and 44.1% (95% CI – 37.9% to 50.3%) were at risk of malnutrition. Older-old (70-79 years), oldest-old (≥80 years), unmarried or widowed, those with chewing and swallowing difficulties, those who screened positive for depression and those who had higher grade of dependency in any activities of daily living were more likely to be malnourished (p < 0.05). Older-old age (aOR – 3.358), depression (aOR – 4.859) and higher grade of dependency in activities of daily living (aOR – 2.940) were the attributes independently associated with malnutrition after adjusting for other factors.

Conclusions:

The older persons in the rural area of Kerala had high burden of malnutrition. Older-old, dependent and depressed individuals are more likely to be affected.

[Impact on the risk of malnutrition and depression of a clinical trial with nutritional educational intervention in non-institutionalized elderly subjects receiving a telecare service in Terrassa (Spain)]

Introduction

Introduction: the elderly are a growing and vulnerable population. Depression and malnutrition are frequent, and there seems to be associated. Objectives: to assess the impact of a nutritional educational intervention on the risk of malnutrition and depression in elderly subjects. Methods: Analytical, experimental, randomized longitudinal study in 38 autonomous, non-institutionalized elderly subjects. Nutritional and depression risk were measured using the Mini Nutritional Assessment (MNA) and the Yesavage Geriatric Depression Scale (GDS-SF), respectively. The impact of the intervention was measured with nutrition and food security questionnaires. Statistics were performed with Spearman's correlation coefficient, and comparisons between means with the Student's t-test. A p-value  0.05 was considered significant. Results: 63.2 % of the sample had a good nutritional status, 28,9 % were at risk of malnutrition, and 7.9 % had malnutrition. Of the total of participants, 28.9 % had depression. A statistically significant, moderate and negative linear relationship was found between depression and nutritional risk (rho = -0.489; p  0.01). The nutritional educational intervention produced a significant increase in knowledge of food security (2.95 ± 2.53 compared to 0.37 ± 1.46; p  0.0005). Conclusions: the risks of malnutrition and depression are significantly associated in older adults. Furthermore, the nutritional educational intervention improved knowledge of food safety, but did not improve nutritional status or in the degree of depression.

Predictors of Incident Malnutrition in Older Irish Adults from the Irish Longitudinal Study on Ageing Cohort-A MaNuEL study

Older adults are at increased risk of malnutrition, which is associated with poorer health, quality of life, and worse disease outcomes. This study identifies predictors of incident malnutrition using data from a subsample (n = 1,841) of The Irish Longitudinal Study on Ageing. Participants were excluded if they were less than 65 years, missing body mass index data at baseline or follow-up, missing baseline weight loss data or malnourished at baseline (body mass index <20 kg/m2 or unplanned weight loss ≥4.5 kg in the previous year). Logistic regression analysis was performed with incident malnutrition (body mass index <20 kg/m2 and/or calculated weight loss >10% over follow-up) as the dependent variable. Factors showing significant (p < .05) univariate associations with incident malnutrition were entered into a multivariate model. The analysis was then repeated, stratified by sex. The 2-year incidence of malnutrition was 10.7%. Unmarried/separated/divorced status (vs married but not widowed), hospitalization in the previous year, difficulties walking 100 m, or climbing stairs independently predicted incident malnutrition at follow-up. When examined by sex, hospitalization in the previous year, falls during follow-up, and self-reported difficulties climbing stairs predicted malnutrition in males. Receiving social support and cognitive impairment predicted malnutrition in females. The development of malnutrition has a range of predictors. These can be assessed using simple questions to identify vulnerable persons.

Prevalence of Malnutrition and Depression in Older Adults Living in Nursing Homes in Mexico City

This study evaluated the association between nutritional status, depressive symptoms, and the number of prescription drugs taken by older adults living in nursing homes in Mexico City. In a cross-sectional study, 262 participants were subjected to anthropometric and nutritional (Mini Nutritional Assessment (MNA)) evaluations; additionally, their depression (Geriatric Depression Scale (GDS)) and functional status were assessed. Multiple logistic regression was used for identifying factors associated with the risk of malnutrition/malnourishment. The mean age of participants was 83.1 ± 8.6 years. A total of 59.9% and 21.1% were at risk of malnutrition and malnourished, respectively. With respect to depression, 27.9% of the participants had mild depression, while 11.4% showed severe depression. An inverse correlation between MNA evaluations and depression scores was found (Spearman's ρ = -0.4624, p < 0.001); residents with a better nutritional status had lower depression scores. Individuals with depressive symptoms were approximately five times more likely to be at risk of malnutrition or malnourished (OR = 5.82, 95% CI = 2.27-14.89) than individuals without depression. Residents taking three or more prescription drugs daily (OR = 1.83, 95% CI = 1.27-2.63, p < 0.001) were more likely to be at risk of malnutrition or malnourished. In summary, poor nutritional status was associated with depression, while the intake of numerous prescription drugs was associated with being at risk of malnutrition or malnourished.

Nutrition assessment and geriatric associated conditions among community dwelling Iranian elderly people

Background

Although malnutrition risk is well documented in elderly care institutions, few studies have been conducted to address concerns regarding community-dwelling elderly people. This study has been aimed to describe the nutritional status and its related socioeconomic and geriatric factors in community-dwelling elders with malnutrition.

Method

For this study, a randomized sampling among people aged 60 has been done (n = 326). Information on nutrition status (full MNA) and health information, like cognitive status (MMSE), daily functional status (ADL and IADL scales) and frailty was obtained. Multiple logistic regression analyses have been carried out, in order to identify the association of demographical and clinical factors with malnutrition.

Results

28.1% of the participants suffered from poor nutrition. In the binary analysis, low MNA scores were associated with increasing age, female gender, lower education level, financial dependence, solitary life, poor self-rated health, multiple physical disabilities and chronic disease, polypharmacy, smoking, functional and cognitive decrease and frailty. In the final model of the multivariate analysis, living alone (OR:1.249,CI:1.105–2.620), multiple physical disabilities (OR:2.183,CI:1.246 ± 3..250) and chronic disease (OR: 2.148,CI:1.167–2.879) were independently associated with malnutrition. Also financial independency (OR:0.625,CI:0.233–0.938), functional ability on ADL (OR:0.536,CI:0.327–0.976) and IADL (OR:0.319,CI:0.194–0.856), normal cognitive (OR:0.456,CI:0.293–0.934) and no frailty (OR:0.253,CI:0.117–0.729) independently were inversely associated with malnutrition. The model was adjusted for all socio- demographic and health variables that were significantly related in the previous models.

Conclusions

Our results indicated a strong correlation between malnutrition and health status. Identifying predictive factors can potentially improve prevention and management strategies used for malnutrition in elderly.

Association between living setting and malnutrition among older adults: The PEN-3S study

OBJECTIVES

Malnutrition is frequent among older adults, especially those living in nursing homes, but the association between residential setting and nutritional status is controversial. The aim of this study was to examine the association between living setting (nursing home versus community) and malnutrition while adjusting for demographic, socioeconomic, health-related, and psychosocial factors.

METHODS

This cross-sectional study included a randomly selected representative sample of Portuguese adults ≥65 y of age. Interviewers collected data regarding demographic and socioeconomic characteristics, nutritional status, physical activity, energy intake, cognitive function, self-reported general health, functional status, symptoms of depression, and loneliness. Logistic regression models were used to estimate the association between residential setting and malnutrition.

RESULTS

Participants were 1186 nursing home residents (72.8% women, 49.2% ≥85 y of age) and 1120 community dwellers (49% women, 21.3% ≥85 y of age). Following Mini Nutritional Assessment (MNA®) criteria, 29.6% of nursing home residents and 14.1% of community dwellers were at risk of malnutrition, whereas 2.3% and 0.3%, respectively, were malnourished. The living setting was not significantly associated with malnutrition after adjusting for functional status, symptoms of depression, and feelings of loneliness (odds ratio, 1.03; 95% confidence interval, 0.67-1.58).

CONCLUSIONS

Risk of malnutrition and malnutrition are more prevalent among nursing home residents than community dwellers. Physical (functional status) and mental health (symptoms of depression and loneliness) seems more relevant to nutritional status than residential setting by itself. These findings should be taken into account when designing public health policies to tackle malnutrition among older adults.

Serum cortisol but not oxidative stress biomarkers are related to frailty: results of a cross-sectional study in Spanish older adults

Frailty is a multidimensional geriatric syndrome of loss of reserves and increased vulnerability to negative health outcomes. Cortisol, the major hormone of the hypothalamic pituitary adrenal (HPA) axis, and oxidative stress may be influenced by multiple endogenous and environmental factors throughout the lifespan, triggering changes in organism functioning. Association of elevated levels of cortisol and oxidative stress biomarkers with aging and several age-related diseases is well documented. However, the possible role of these factors on frailty status in older adults has not been extensively studied. Hence, the aim of this study was to conduct a cross-sectional study in 252 older adults (≥65 years old) classified according to their frailty status. Plasma cortisol and biomarkers related to oxidative stress including reactive oxygen/nitrogen species, oxidative DNA damage, and total antioxidant capacity were determined in non-frail, pre-frail, and frail subjects. Results showed significantly increasing cortisol concentrations with frailty burden, but no marked association between any oxidative stress biomarker and frailty status. In addition, dependence on activities of daily living and 10-year mortality risk were also correlated with elevated cortisol levels. Current results support the hypothesis that age-related HPA axis dysregulation is associated with frailty status, although further research is necessary to establish the role of cortisol in the pathophysiology of frailty.

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.

Malnutrition in older adults: screening and determinants

Older adults are at risk of protein-energy malnutrition (PEM). PEM detrimentally impacts on health, cognitive and physical functioning and quality of life. Given these negative health outcomes in the context of an ageing global population, the Healthy Diet for a Healthy Life Joint Programming Initiative Malnutrition in the Elderly (MaNuEL) sought to create a knowledge hub on malnutrition in older adults. This review summarises the findings related to the screening and determinants of malnutrition. Based on a scoring system that incorporated validity, parameters used and practicability, recommendations on setting-specific screening tools for use with older adults were made. These are: DETERMINE your health checklist for the community, Nutritional Form for the Elderly for rehabilitation, Short Nutritional Assessment Questionnaire-Residential Care for residential care and Malnutrition Screening Tool or Mini Nutritional Assessment-Short Form for hospitals. A meta-analysis was conducted on six longitudinal studies from MaNuEL partner countries to identify the determinants of malnutrition. Increasing age, unmarried/separated/divorced status (vs. married but not widowed), difficulties walking 100 m or climbing stairs and hospitalisation in the year prior to baseline or during follow-up predicted malnutrition. The sex-specific predictors of malnutrition were explored within The Irish Longitudinal Study of Ageing dataset. For females, cognitive impairment or receiving social support predicted malnutrition. The predictors for males were falling in the previous 2 years, hospitalisation in the past year and self-reported difficulties in climbing stairs. Incorporation of these findings into public health policy and clinical practice would support the early identification and management of malnutrition.

Frailty in Older Adults Is Associated With Plasma Concentrations of Inflammatory Mediators but Not With Lymphocyte Subpopulations

Frailty denotes a multidimensional syndrome that gives rise to vulnerability to stressors and leads to an increase of the age-related decline of different physiological systems and cognitive abilities. Aging-related alterations of the immune system may compromise its competence culminating in a chronic low-grade inflammation state. Thus, it has been proposed that frailty is associated with alterations in the concentration of pro-inflammatory molecules and in different lymphocyte subpopulations. To provide further support to the validity of that hypothesis, we conducted a cross-sectional study in a population of Spanish older adults (N = 259, aged 65 and over) classified according to their frailty status. Biomarkers analyzed included percentages of several lymphocyte subsets and several inflammation mediators, namely concentrations of interleukin 6 (IL6), C-reactive protein (CRP), tumor necrosis factor α (TNFα), and 75 kDa soluble TNFα receptor II (sTNF-RII). Reference ranges for the inflammation mediators were established for the first time in robust older adults. A significant increase in the CD4+/CD8+ ratio and a significant decrease in the % CD19+ cells were observed in the frail group. Progressive increases with frailty severity were obtained in all inflammatory mediator concentrations, especially notable for IL6 and sTNF-RII. Area under the receiver-operating characteristic curve obtained for sTNF-RII (0.90, 95% CI 0.85-0.94, P < 0.001) indicates a high accuracy in the predictive value of this biomarker for frailty. Although results from the current study revealed limited strength associations between frailty and the lymphocyte subsets assessed, data obtained for the inflammatory mediators provide further support to involvement of inflammaging in frailty status in older adults.

Updates in nutrition and polypharmacy

PURPOSE OF REVIEW

Medications have the potential to affect nutritional status in negative ways, especially as the number of medications increase. The inter-relation between polypharmacy and malnutrition is complex and not fully delineated in previous studies. More research has been done and compiled in the last year, which helps to clarify this relationship. This review brings together the most recent literature with the previous research to help healthcare providers to better assess and manage medication therapy in older adults.

RECENT FINDINGS

Recent evidence confirms a synergistic negative effect of polypharmacy and malnutrition on outcomes of older adults. In addition, several drug classes, including common antihypertensive agents, acetylcholinesterase inhibitors, multivitamins, proton pump inhibitors, HMG-CoA reductase inhibitors (statins), antiplatelet agents and metformin, have been implicated in important drug-nutrient interactions. These are reviewed in detail here. Ongoing research endeavors are described.

SUMMARY

Healthcare practitioners can use this review to identify potentially inappropriate medications and patients at highest risk of experiencing a medication-related adverse reaction in order to systematically deprescribe these high-risk medications.

High Prevalence of Physical Frailty Among Community-Dwelling Malnourished Older Adults-A Systematic Review and Meta-Analysis

BACKGROUND

Malnutrition and frailty are two geriatric syndromes that significantly affect independent living and health in community-dwelling older adults. Although the pathophysiology of malnutrition and physical frailty share common pathways, it is unknown to what extent these syndromes overlap and how they relate to each other.

METHODS

A systematic review was performed resulting in a selection of 28 studies that assessed both malnutrition and frailty in community-dwelling older adults. Furthermore, a meta-analysis was performed on 10 studies that used Mini- Nutritional Assessment and the Fried frailty phenotype to estimate the prevalence of malnutrition within physical frailty and vice versa.

RESULTS

In the systematic review, 25 of the 28 studies used the Mini-Nutritional Assessment (long or short form) for malnutrition screening. For frailty assessment, 23 of the 28 studies focused on the physical frailty phenotype, of which 19 followed the original Fried phenotype. Fifteen studies analyzed the association between malnutrition and frailty, which was significant in 12 of these. The meta-analysis included 10 studies with a total of 5447 older adults. In this pooled population of community-dwelling older adults [mean (standard deviation) age: 77.2 (6.7) years], 2.3% was characterized as malnourished and 19.1% as physically frail. The prevalence of malnutrition was significantly associated with the prevalence of physical frailty (P < .0001). However, the syndromes were not interchangeable: 68% of the malnourished older adults was physically frail, whereas only 8.4% of the physical frail population was malnourished.

CONCLUSIONS

The systematic review and meta-analysis revealed that malnutrition and physical frailty in community-dwelling older adults are related, but not interchangeable geriatric syndromes. Two out of 3 malnourished older adults were physically frail, whereas close to 10% of the physically frail older adults was identified as malnourished.

Nutritional Strategies Facing an Older Demographic: The Nutrition UP 65 Study Protocol

Background

The population of Portugal is aging. The lack of data on older adults’ nutritional status and the lack of nutrition knowledge amongst health professionals, caregivers, and older adults themselves, remains a challenge.

Objective

The Nutrition UP 65 study aims to reduce nutritional inequalities in the older Portuguese adult population and improve knowledge regarding older Portuguese adults’ nutritional status, specifically relating to undernutrition, obesity, sarcopenia, frailty, hydration, sodium, and vitamin D statuses.

Methods

A representative sample of older Portuguese adults was selected. Sociodemographic, lifestyle, anthropometric, functional, and clinical data were collected. Sodium excretion, hydration, and vitamin D statuses were assessed.

Results

Data collection (n=1500) took place between December, 2015 and June, 2016. Results will be disseminated in national and international scientific journals, and via Portuguese media.

Conclusions

Nutrition UP 65 results will provide evidence for the design and implementation of effective preventive public health strategies regarding the elderly. These insights may represent relevant health gains and costs savings.
