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

Objectives

Health-related quality of life (HRQoL) is a multidimensional health measurement and a key to optimal aging. The aim of this study was to examine the association of nutritional status with HRQoL in the elderly.

Design

Cross-sectional study.

Setting

Villanueva Older Health Study, a community-based study in Villanueva de la Cañada (Madrid, Spain).

Participants

83 (53 women) non-institutionalized inhabitants aged 80 years and above.

Measurement

HRQoL was assessed by EuroQoL-5D (EQ-5D) questionnaire, nutritional risk by Mini Nutritional Assessment (MNA) questionnaire and dietary intake by 24-hour dietary recall. Statistical significance was evaluated at 95% confidence level (P< 0.05).

Results

EQ-5D pointed out differences between men and women (0.782±0.235 and 0.633±0.247; p=0.02). Problems in mobility (total sample) and pain/discomfort (women) dimensions were most frequently reported. MNA (26.5±3.2 men and 24.3±3.2 women; p=0.03) revealed malnutrition in 3.3% of men and 1.9% of women, and risk of malnutrition in 6.7% and 37.7%, respectively. Total sample was at risk of folic acid, zinc, magnesium, vitamin D and vitamin E deficiency. EQ-5D was associated with MNA (p<0.001). EQ-5Dindex was associated with energy intake (p=0.04) and EQ-5Dvas was negatively correlated with body mass index (p=0.02). EQ-5D pain/discomfort dimension was associated with energy (p=0.006), protein (p=0.005), lipid (p=0.03), magnesium (p=0.032), phosphorus (p=0.012), selenium (p=0.043) and niacin (p=0.004) intake.

Conclusions

Women showed poorer HRQoL and higher malnutrition risk. A relationship between HRQoL and risk of malnutrition was observed. Results suggest that when energy and protein, lipid, phosphorus, magnesium, selenium and niacin intake increase, HRQoL is promoted, although the increase does not seem to have a strong direct effect on it. The limited influence of energy and nutrient intake on HRQoL observed requires further research.     

Nutritional status according to Mini Nutritional Assessment is related to functional status in geriatric patients — independent of health status

Objectives

The aim of this study was to investigate the relationship between nutritional and functional status in acute geriatric patients including mobility and considering health status.

Design

Cross-sectional study.

Setting

Hospital.

Participants

205 geriatric patients (median age 82.0 (IQR: 80–86) years, 69.3% women).

Measurements

Nutritional status was determined by Mini Nutritional Assessment (MNA) and patients were categorized as well-nourished (≥ 24 points), at risk of malnutrition (17–23.5 points) or as malnourished (< 17 points). Functional status was determined by Barthel Index (BI) and Timed ‘Up and Go’ Test (TUG) and related to MNA categories. Using binary multiple logistic regression the impact of nutritional status on functional status was examined, adjusted for health status.

Results

60.3 % of the patients were at risk of malnutrition and 29.8 % were malnourished. Ability to perform basic activities of daily living (ADL) decreased with declining nutritional status. The proportion of patients unable to perform the TUG increased with worsening of nutritional status (45.0 % vs. 50.4 % vs. 77.0 %, p<0.01). After adjusting for age, gender, number of diagnoses, disease severity and cognitive function, a higher MNA score significantly lowered the risk of being dependent in ADL (OR 0.85, 95 % CI 0.77–0.94) and inability to perform the TUG (OR 0.90, 95 % CI 0.82–0.99).

Conclusion

Nutritional status according to MNA was related to ADL as well as to mobility in acute geriatric patients. This association remained after adjusting for health status.     

An empirical comparison of the measurement properties of the EQ-5D-5L,DEMQOL-U and DEMQOL-Proxy-U for older people in residential care

Purpose

This study aimed to empirically compare the measurement properties of self-reported and proxy-reported (in cases of severe cognitive impairment) generic (EQ-5D-5L) and condition-specific (DEMQOL-U and DEMQOL-Proxy-U) preference-based HRQoL instruments in residential care, where the population is characterised by older people with high rates of cognitive impairment, dementia and disability.

Methods

Participants were recruited from seventeen residential care facilities across four Australian states. One hundred and forty-three participants self-completed the EQ-5D-5L and the DEMQOL-U while three hundred and eight-seven proxy completed (due to the presence of severe dementia) the EQ-5D-5L and DEMQOL-Proxy-U. The convergent validity of the outcome measures and known group validity relative to a series of clinical outcome measures were assessed.

Results

Results satisfy convergent validity among the outcome measures. EQ-5D-5L and DEMQOL-U utilities were found to be significantly correlated with each other (p?<?0.01) as were EQ-5D-5L and DEMQOL-Proxy-U utilities (p?<?0.01). Both self-reported and proxy-reported EQ-5D-5L utilities demonstrated strong known group validity in relation to clinically recognised thresholds of cognition and physical functioning, while in contrast neither DEMQOL-U nor DEMQOL-Proxy-U demonstrated this association.

Conclusions

The findings suggest that the EQ-5D-5L, DEMQOL-U and DEMQOL-Proxy-U capture distinct aspects of HRQoL for this population. The measurement and valuation of HRQoL form an essential component of economic evaluation in residential care. However, high levels of cognitive impairment may preclude self-completion for a majority. Further research is needed to determine cognition thresholds beyond which an individual is unable to reliably self-report their own health-related quality of life.

     

Assessment of health-related quality of life among hypertensive patients: a cross-sectional study from Palestine

Aim

The ability to identify indicators of poor health-related quality of life (HRQoL) is crucial for both improving clinical care and determining targets of intervention for the prevention and treatment of disease. The main objectives of this study were to assess the HRQoL profile of the hypertensive population from Palestine, and to determine the socio-demographic and clinical characteristics associated with poor HRQoL.

Subject and methods

A cross sectional study was conducted, adopting the EuroQoL-5 Dimensions scale (EQ-5D-5 L) for the assessment of HRQoL. Hypertensive patients attending outpatients’ clinics at Al-Makhfyah primary health care clinic and from Alwatani Hospital, Nablus, Palestine were approached for study.

Results

Four hundred and ten hypertensive patients were enrolled in the study. Of these, 213 patients (52 %) were female. The average age of the study population was 58.38?±?10.65 years. HRQoL was good, with a mean EQ-5D-5 L index value and EQ visual analogue scale (EQ-VAS) score of 0.80?±?0.16 and 74.1?±?15.6 respectively. There was a significant positive correlation (r?=?0.56; p?<?0.001) between the EQ-5D-5 L index values and the reported EQ-VAS scores. A significant difference in EQ-5D-5 L index values was found among participants when grouped according to age, occupation, marital status, income, educational level, duration of disease, total number of chronic diseases, and total number of medications (Kruskal–Wallis test; p-value?<?0.05), as well as gender and therapy type (Mann–Whitney test, p-value?<?0.05).

Conclusions

This study highlighted that specific socio-demographic and disease-related characteristics of hypertensive patients as well as treatment factors were strongly associated with HRQoL. The study findings could be helpful in clinical practice, mainly in the early treatment of hypertensive patients, at a point where improving HRQoL is still possible.     

Validation and comparison of 15-D and EQ-5D-5L instruments in a Spanish Parkinson’s disease population sample

Purpose

To contribute to the ongoing discussion on the choice of a preference-based health-related quality of life (HRQoL) instrument to be used in cost-effectiveness analysis by studying and comparing the validity, sensitivity and relative efficiency of 15-D and EuroQol 5D 5L (EQ-5D-5L) in a Spanish Parkinson’s disease (PD) population sample.

Methods

One hundred and thirty-three volunteers were asked to complete an interview using 15-D and EQ-5D-5L. Spearman’s rank correlation coefficient (r) was used to test the convergent validity of these instruments with specific PD measures. Sensitivity and efficiency were compared using receiver operating characteristic (ROC) curves and relative efficiency statistic, respectively.

Results

A strong correlation (r > 0.65; p < 0.001) was found between both 15-D and EQ-5D-5L utilities with the summary score of the PDQ-8, and a strong correlation (r > 0.50; p < 0.001) was found between 15-D and EQ-5D-5L utilities with the EQ-VAS. The areas under the ROC of both instruments all exceeded 0.5 (p < 0.001). The 15-D instrument was 4.1–29.8 % less efficient at detecting differences between patients with optimal HRQoL, while this instrument was 11 % more efficient at detecting differences between patients at mild and moderate to strong severity of the PD symptoms.

Conclusions

15-D and EQ-5D-5L are showed to be valid and sensitivity generic HRQoL measures in Spanish PD patients with both instruments showing similar HRQoL dimension coverage and ceiling/floor effects. The 15-D has better efficiency and greater sensitivity to detect clinical changes in PD severity of the symptoms meanwhile the EQ-5D-5L is better to detect clinical HRQoL changes. Additionally, the EQ-5D-5L questionnaire requires less time than 15-D to be administered, and it might be more appropriate for studies conducted in Spain, since a country-specific “value set” is available for this instrument and not for the 15-D.     

The mediating effects of depressive symptoms on nutritional status of older adults in long-term care facilities

Objective

To test whether depressive symptoms mediate the effects of activities of daily living (ADLs) on nutritional status of older adults living in long-term care (LTC) facilities in Taiwan.

Design

A cross-sectional study.

Setting

Seventy-three community-based LTC facilities in northern Taiwan.

Participants

This study sampled 306 adults ranging in age from 65 to 97 years who were free of acute infection or disease and who were able to communicate.

Measurements

Nutritional status was assessed by the Mini-Nutritional Assessment (MNA) scale and depressive symptoms were assessed by the short form of the Geriatric Depressive Scale (GDSSF).

Results

MNA scores revealed that 65% of the subjects were at risk for malnutrition (17 to 23.5 points). In addition, depressive symptoms partially mediated the relationship between ADLs and nutritional status, with 10.7% of the effect of depressive symptoms on nutritional status going through the mediator.

Conclusion

Interventions to reduce depressive symptoms among institutionalized older adults should focus on improving nutritional status rather than promoting ADLs, which are believed to be difficult to change.     

Comparing the psychometric properties of the EQ-5D-3L and EQ-5D-5L in cancer patients in Korea

Purpose

This study was conducted to assess the redistribution properties of the EQ-5D-3L when using the EQ-5D-5L and to compare the validity, informativity, and reliability of both EQ-5D-3L and EQ-5D-5L in Korean cancer patients.

Methods

Patients visiting one ambulatory cancer center self-administered the two versions of the EQ-5D and the EORTC QLQ-C30 questionnaire. Redistribution properties in each dimension of EQ-5D were analyzed between EQ-5D-3L and EQ-5D-5L. Informativity was evaluated using the Shannon entropy and ceiling effect. Convergent validity was evaluated by comparing the EQ-VAS, ECOG performance status, and EORTC QLQ-C30 subscales. Reliability was also evaluated in terms of test?Cretest reliability.

Results

All levels of the EQ-5D-3L substantially partitioned into associated levels of the EQ-5D-5L. The average inconsistency rate of the two versions was 3.5%. Absolute informativity was higher for the EQ-5D-5L than for the EQ-5D-3L, but their informative efficiency tended to be similar. The proportion of ??perfect health?? (11111) decreased from 16.8% in the EQ-5D-3L to 9.7% in the EQ-5D-5L. EQ-5D-5L demonstrated similar or higher correlations with the EQ-VAS, ECOG performance status, and EORTC QLQ-C30, than the EQ-5D-3L. The intraclass correlation coefficient of the EQ-5D-5L index was 0.77.

Conclusions

The EQ-5D-5L had greater informativity and lower rate in the ceiling effect than those values of the EQ-5D-3L. The EQ-5D-5L showed good construct validity and reasonable reliability. Therefore, considering these findings, the EQ-5D-5L may be preferable to the EQ-5D-3L.     

Psychometric properties of the EuroQol Five Dimensional Questionnaire (EQ-5D-3L) in caregivers of autistic children

Purpose

This study aimed to ascertain the psychometric properties of EuroQol Five Dimensional Questionnaire (EQ-5D-3L) in primary caregivers of children with autism. The convergent validity, discriminant validity, known-groups validity, internal consistency reliability, and floor and ceiling effects of EQ-5D-3L were analyzed.

Methods

A cross-sectional design was used for study purposes. Through an online survey, relevant study information was collected from 316 primary caregivers of children with autism. Study participants were from families of children with autism living in the United States who were registered with the Interactive Autism Network. Convergent validity of the EQ-5D-3L was assessed through its correlation with other measures of similar constructs. Discriminant validity was assessed by observing the correlation of EQ-5D-3L domains with theoretically unrelated constructs. Known-groups validity was tested by comparing EQ-5D-3L index and visual analog scale (VAS) scores across levels of autism severity among the care recipients. Internal consistency reliability of EQ-5D-3L was tested. Lastly, floor and ceiling effects of EQ-5D-3L were assessed.

Results

More than 60 % of participants reported problems of ‘anxiety/depression.’ Convergent and discriminant validity of the EQ-5D-3L was good. Significant correlation (convergent validity) was observed among EQ-5D-3L index and VAS and (SF-12v2) physical component summary and mental component summary scores. Caregivers’ EQ-5D-3L index and VAS scores varied by levels of autism severity among care recipients, providing evidence of known-groups validity. Reliability assessed through Cronbach’s alpha was less than satisfactory; however, corrected item-total correlations were adequate.

Conclusions

The EQ-5D-3L is a psychometrically sound tool to elicit health state preferences among caregivers of children with autism.     

Effects of individual dietary counseling as part of a Comprehensive Geriatric Assessment (CGA) on nutritional status: A population-based intervention study

Background

Nutritional risk is relatively common in community-dwelling older people.

Objective

To objective of this study was to evaluate the effects of individual dietary counseling as part of a Comprehensive Geriatric Assessment on nutritional status among community-dwelling people aged 75 years or older.

Methods

Data were obtained from a subpopulation of participants in the population-based Geriatric Multidisciplinary Strategy for the Good Care of the Elderly (GeMS) intervention study in 2004 to 2007. In the present study, the population consist 173 persons at risk of malnutrition in the year 2005 in an intervention (n=84) and control group (n=89). Nutritional status, body weight, body mass index, serum albumin were performed at the beginning of the study and at a two-year follow-up. The nutritional screening was performed using the Mini Nutritional Assessment (MNA) test.

Results

A increase in MNA scores (1.8 95% confidence interval [CI]: 0.7 to 2.0) and in serum albumin (0.8 g/L, 95% CI: 0.2 to 0.9 g/L) were a significant difference between the groups.

Conclusions

Nutritional intervention, even dietary counseling without nutritional supplements, may improve nutritional status.     

Comparison of the measurement properties between a short and generic instrument, the 5-level EuroQoL Group’s 5-dimension (EQ-5D-5L) questionnaire, and a longer and disease-specific instrument, the Functional Assessment of Cancer Therapy—Breast (FACT-B), in Asian breast cancer patients

Purpose

To compare the measurement precision and related properties between the 5-level EuroQoL Group’s 5-dimension (EQ-5D-5L) questionnaire and the Functional Assessment of Cancer Therapy—Breast (FACT-B) questionnaire in assessing breast cancer patients.

Methods

An observational study of 269 Singaporean breast cancer patients. To compare discriminative ability and responsiveness, the effect sizes (in standard deviation) of the EQ-5D-5L and the FACT-B in relation to health indicators and the change in performance status or quality of life were estimated. Test–retest reliability was examined using the intraclass correlation (ICC).

Results

Using performance status, evidence of disease, and treatment status as the criteria, the differences (FACT-B minus EQ-5D-5L) in the effect size for discriminative ability were negative or closed to zero, and the 90 % confidence intervals totally fell within the zone that indicated the non-inferiority of the EQ-5D-5L. For responsiveness and test–retest reliability, the confidence intervals of the differences in effect size and ICC overlapped the non-inferiority margin; thus, non-inferiority in these two aspects could neither be confirmed nor rejected.

Conclusions

The EQ-5D-5L was non-inferior to the FACT-B in discriminating breast cancer patients with different health conditions cross-sectionally. The EQ-5D-5L serves as a reasonable alternative or supplementary instrument to the FACT-B in assessing breast cancer patients’ health outcomes.     

Health-related quality of life of children and adolescents with functional disabilities in a northern Swedish county

Purpose

Health-related quality of life (HRQoL) studies in children and adolescents with disabilities tend to report lower self-reported health than in the typical population. However, reports are not always consistent and HRQoL appears to vary depending on diagnosis, cultural setting and clinical context. The aim of this study was to explore HRQoL in children and adolescents with various disabilities in Västerbotten County, Sweden.

Methods

A total of 175 children and adolescents [57 girls, 118 boys; mean age 11.7 years (range 7–17 years)] divided into four different diagnostic groups (intellectual disabilities, autism spectrum disorders, movement disorders and hearing disabilities) participated in the study. The EuroQol Five Dimensions Health Questionnaire, Youth version (EQ-5D-Y) was used as HRQoL measure.

Results

Significant differences in various EQ-5D-Y dimensions between the different diagnostic groups were found, but no differences in overall health status. HRQoL in children and adolescents with hearing disabilities was found similar to the typical child population in Sweden whereas children and adolescents with other diagnoses reported evidently more problems.

Conclusions

Findings suggest that there is an increased risk for children with functional disabilities other than hearing disabilities in northern Sweden to experience difficulties in various health domains and lowered general health.     

Health-related quality of life among breast,prostate, and colorectal cancer patients with end-stage disease

Purpose

To explore end-stage breast, prostate, and colorectal cancer patients’ health-related quality of life (HRQoL); to compare results obtained by different HRQoL instruments; and to explore factors related to impaired HRQoL.

Methods

A cross-sectional observational study utilized two generic HRQoL instruments, the 15D and the EQ-5D, and a cancer-specific instrument, the EORTC QLQ-C30. Patients were recruited from the Helsinki University Hospital’s Department of Oncology and from a local hospice.

Results

Of the 114 palliative care patients included in the analysis, 27 had breast cancer, 30 had prostate cancer, and 57 had colorectal cancer. Of these, 28 % died within 3 months after their response, while 32 % died within three to 6 months, and 39 % died more than 6 months after. Utility values varied widely by instrument: the 15D gave the highest utility values and VAS the lowest (15D: 0.74, EQ-5D: 0.59 and VAS: 55). Patients close to death had lower HRQoL scores independently from the instrument used. The EQ-5D showed a pronounced ceiling effect, with 13 % of patients reporting full health, whereas the corresponding figures for the 15D and VAS were 1 and 0 %, respectively. Fatigue was the most common symptom and also predicted impaired HRQoL most significantly.

Conclusions

All instruments were applicable for the evaluation of HRQoL among end-stage cancer patients. Fatigue seemed to be the most significant deteriorating factor, whereas clinical and demographic factors had less of an effect on HRQoL.     

Nutritional status of geriatric outpatients with systolic heart failure and its prognostic value regarding death or hospitalization, biomarkers and quality of life

Introduction

The prevalence of malnutrition in ambulatory patients with heart failure is difficult to determine, depending on the timing and methodology.

Objective

To determine the nutritional status of outpatients with systolic heart failure with the Mini Nutritional Assessment (MNA) full and short-form versions, and evaluate its relationship with the short-term prognosis, biomarkers and quality of life.

Methods

Fifty consecutive (70% male), geriatric (74.3+ 6.2years old) stable outpatient with heart failure (NYHA class II 68%, III 32%) and left ventricular ejection fraction of 26.7 +11.5% were included and followed during 12 months. At a routine visit to the heart failure clinic, the MNA, the Minnesota Living with Heart Failure questionnaire (MLHFQ) were applied. According to the MNA screening score the nutritional status was classified using the MNA full (MNA-F) and the short-form (MNA-F) versions of the questionnaire. The recorded events were death and hospitalization. Statistics: The-survival and hospitalizations curves were evaluated with the Log-Rank test and Cox Regression analysis. The association between parameters was analyzed with the Pearson and Spearmann correlation coefficient.

Results

(1) The mortality and hospitalization rates were 12% and 42%, respectively. (2) With the MNA-SF 7.6% of the patients had malnutrition and 20% were at risk of malnutrition. There was a good agreement (90%) between the MNA-SF and the MNA-F classifications. (3) There was a significant relationship between the MNA screening score and the MLHFQ (rs= ?0.592 p<0.00l), Nt-ProBNP (rs= ?0.49 p<0.001) and total plasma protein (r= 0.672 p=0.006); (3) The-MNA-SF nutritional classification was associated with the 12 months survival (Log-Rank p=0.044) and hospitalization (Log-Rank p=0.005) curves. (4) Those patients with malnutrition by the MNA-SF were at greater risk of death (HR= 8.0 p=0.059) and hospitalization (HR 8.1 p=0.008).

Conclusion

The MNA is useful for the evaluation of the nutritional status of elderly outpatients with systolic heart failure. It is a good predictor of the short-term outcome and is also associated with the quality of life and Nt-ProBNP.     

Health-related quality of life as measured by the EQ-5D in the prevention,screening and management of cervical disease: A systematic review

Purpose

Cost-effectiveness analyses (CEAs) of screening can be highly sensitive to the health-related quality of life (HRQoL) effects of screen tests and subsequent treatment. Accordingly, accurate assessment of HRQoL is essential. We reviewed the literature regarding HRQoL in cervical prevention and management in order to appraise the current evidence regarding this important input to CEA.

Methods

We searched the MEDLINE, Scopus and EconLit databases for studies that estimated HRQoL in cervical cancer prevention and management published January 1995–December 2015. The primary inclusion criterion was for studies that assess HRQoL using the EQ-5D. Data were abstracted from eligible studies on setting, elicitation group, sample size, elicitation instruments, health state valuations, study design and follow-up. We assessed the quality and comparability of the studies with a particular focus on the HRQoL reported across states and groups.

Results

Fifteen papers met the inclusion criteria. Most used patient elicitation groups (n = 11), 2 used the general public and 2 used a mix of both. Eight studies were cross-sectional and seven were longitudinal. Six studies used both the EQ-5D-3L and the EQ-VAS together with other measures of overall HRQoL or condition-specific instruments. Extensive heterogeneity was observed across study characteristics.

Conclusions

Our results reveal the challenges of sourcing reliable estimates of HRQoL for use in CEAs of cervical cancer prevention and treatment. The EQ-5D appears insufficiently sensitive for some health states. A more general problem is the paucity of HRQoL estimates for many health states and their change over time.

     

The quality of life in Chinese population with chronic non-communicable diseases according to EQ-5D-3L: a systematic review

Purpose

Over the past decade, a changing spectrum of disease has turned chronic non-communicable diseases (CNCDs) into the leading cause of death worldwide. During the 2015 in China, there were more than 6.6 million deaths from NCDs, which was the highest rate around the world. In the present study, we performed a systematic review to analyze the health-related quality of life (HRQoL) according to EQ-5D-3L instrument in patients with different kinds of CNCDs in China.

Methods

We searched PubMed, Embase, Web of Science, Cochrane Library, VIP, WanFang Data, and CNKI databases up to April 12, 2018, to identify all relevant studies that reported on HRQoL assessed by EQ-5D-3L instrument in Chinese patients with CNCDs. Expert consultation and hand-searching of reference lists from retrieved studies were employed to identify additional references. The variation of mean utility values, EQ-VAS score ranges, and responses for each EQ-5D dimension described in relevant studies were extracted.

Results

A total of 5027 English-language articles and 618 Chinese-language articles were identified, among which 38 articles met full inclusion criteria. These 38 studies involved 18 kinds of CNCDs. In this review, the health utility for diabetes mellitus ranged from 0.79 to 0.94 (EQ-5D VAS scores from 61.5 to 78.6), hypertension from 0.78 to 0.93 (70.1–77.4), coronary heart disease from 0.75 to 0.90 (71.0–77.0), chronic obstructive pulmonary disease from 0.64 to 0.80 (55.0–67.0), epilepsy from 0.83 to 0.87 (78.3–79.6), cerebral infarction from 0.51 to 0.75 (49.7–79.0), while children cerebral palsy was 0.44 (27.3).

Conclusions

EQ-5D-3L is widely used in studies of HRQoL associated with CNCDs in China. Our results suggest that many factors may influence the measurement results of health utilities, including age, gender, sample source, comorbidities, rural/urban, and EQ-5D-3L value sets.

     

Nutritional status of community-dwelling elderly with newly diagnosed Alzheimer’s disease: Prevalence of malnutrition and the relation of various factors to nutritional status

Objetives

To determine the prevalence of malnutrition and its relation to various factors in community-dwelling elderly with newly diagnosed Alzheimer’s disease (AD).

Design

Retrospective crosssectional study.

Setting

Memory clinic in a rural part of the Netherlands.

Participants

312 Community-dwelling AD patients, aged 65 years or older, were included.

Measurements

At the time the diagnosis AD was made, socio-demographic characteristics and data on nutritional status (Mini Nutritional Assessment (MNA)), cognitive function (Mini Mental State Examination (MMSE), Cambridge Cognitive Examination (Camcog)), functional status (Interview for Deterioration in Daily Living Activities in Dementia (IDDD), Barthel Index (BI)) and behaviour (Revised Memory and Behaviour Problems Checklist (RMBPC)) were assessed. Characteristics of well-nourished patients (MNA score >23.5) were compared to characteristics of patients at risk of malnutrition (MNA score 17–23.5). Linear regression analysis was performed to assess the effect of various factors on nutritional status.

Results

The prevalence of malnutrition was 0% and 14.1% was at risk of malnutrition. AD patients at risk of malnutrition were more impaired in basic and complex daily functioning than well-nourished AD patients (median IDDD score 41.5 [25th–75th percentile 38.8–48.0] versus median IDDD score 40.0 [25th–75th percentile 37.0–43.0], p = 0.028). The degree of impairment in basic and complex daily functioning (IDDD) was independently related to nutritional status (MNA) (p = 0.001, B = ?0.062).

Conclusion

One in seven community-dwelling elderly with newly diagnosed AD is at risk of malnutrition. The degree of impairment in daily functioning is independently related to nutritional status. Therefore, assessment of the nutritional status should be included in the comprehensive assessment of AD patients. The relation between daily functioning, nutritional status and AD warrants further investigation.     

Different components of nutritional status in older inpatients with cognitive impairment

Objectives

To evaluate different components of nutritional status in older patients with cognitive deficit, particularly in those with mild cognitive impairment (MCI).

Design

Cross-sectional study.

Setting and participants

560 elderly subjects aged ?? 65 years consecutively admitted to an acute Geriatric Unit of Apulia region of southern Italy.

Measurements

A standardized comprehensive geriatric assessment was used to evaluate medical, cognitive, affective and social aspects. Nutritional status was assessed using the mini nutritional assessment (MNA). The cognitive function was categorized into three levels ?? MCI, dementia or normal cognition (NoCI) ?? according to the neuropsychological test score.

Results

Subjects with cognitive decline had significantly lower frequency of well-nourished (MCI=10%, dementia=8%, NoCI=22%, p<0.05) and higher frequency of malnourished (MCI=47%, dementia=62%, NoCI=19%, p<0.001) than patients with normal cognition. Similarly, MNA total score, MNA-3 and MNA-4 subscores were significantly lower in patients with MCI and dementia than patients with normal cognition (p<0.001).

Conclusions

These results suggest that cognitive decline may be associated with malnutrition in this sample of hospitalized older patients. Dietary habits (MNA-3) and subjective assessment of self-perceived quality of health and nutrition (MNA-4) are particularly poor also in patients with MCI and could be. very important variables to be considered in the multidimensional evaluation of subjects with cognitive impairment.
