Nutritional status in chronically-ill elderly patients. Is it related to quality of life?

Objective

The aim of this study is to assess the quality of life in chronically-ill elderly patients and its relationship with parameters concerning the patients’ nutritional status.

Design

A cross-sectional study.

Setting

Primary health-care centres in Jaen, Spain.

Participants

A total of 168 chronically-ill elderly outpatients aged from 65 to 89 years.

Measurements

Quality of life was measured using the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire. A nutritional assessment was undertaken including socio-demographic variables, anthropometric measurements (body-mass index and calf circumference), functional evaluation (Barthel index and Folstein mini-mental status test) and a dietetic questionnaire. The mini-nutritional assessment test was used as an assessment tool to detect nutritional risk.

Results

Quality of life in chronically-ill elderly subjects, as determined by the WHOQOL-BREF questionnaire, which diminishes with age, is independent of anthropometric parameters and a statistically significant difference was found between gender, socio-demographic characteristics, functional capacity, nutritional status and the kind of chronic disease (p<0.05).

Conclusion

The relationship between the quality of life with the patients’ socio-demographic characteristics, functional capacity and nutritional status underlines the importance of taking these factors into account in the management of chronically ill patients, especially women.     

Nutritional status according to the Mini Nutritional Assessment (MNA®) and frailty in community dwelling older persons: A close relationship

Objective

This study investigates the association between MNA results and frailty status in community-dwelling older adults. In addition the relevance of singular MNA items and subscores in this regard was tested.

Design

Cross-sectional study.

Setting

Community-dwelling older adults were recruited in the region of Nürnberg, Germany.

Participants

206 volunteers aged 75 years or older without cognitive impairment (Mini Mental State Examination >24 points), 66.0% female.

Measurements

Frailty was defined according to Fried et al. as presence of three, pre-frailty as presence of one or two of the following criteria: weight loss, exhaustion, low physical activity, low handgrip strength and slow walking speed. Malnutrition (<17 points) and the risk of malnutrition (17–23.5 points) were determined by MNA®.

Results

15.1% of the participants were at risk of malnutrition, no participant was malnourished. 15.5 % were frail, 39.8% pre-frail and 44.7% non-frail. 46.9% of the frail, 12.2% of the pre-frail and 2.2% of the non-frail participants were at risk of malnutrition (p<0.001). Hence, 90% of those at risk of malnutrition were either pre-frail or frail. For the anthropometric, dietary, subjective and functional, but not for the general MNA subscore, frail participants scored significantly lower than pre-frail (p<0.01), and non-frail participants (p<0.01). Twelve of the 18 MNA items were also significantly associated with frailty (p<0.05).

Conclusions

These results underline the close association between frailty syndrome and nutritional status in older persons. A profound understanding of the interdependency of these two geriatric concepts will represent the basis for successful treatment strategies.     

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.

Nutritional status and dietary habits in Parkinson’s disease patients in Ghana

ObjectiveDietary treatment is important for the management of Parkinson’s disease (PD). Our objective was to describe the dietary habits and assess the nutritional status of Ghanaian patients with PD. This study is part of a larger project, for which Ghana has been selected as a pilot country.MethodsFifty-five Ghanaian patients with PD and 12 healthy Ghanaian controls were recruited. We assessed nutritional status, investigated dietary habits, and assessed the prevalence of the nutritional complications of PD (e.g., constipation and dysphagia).ResultsThe mean daily caloric intake was about 1200 kcal/d in patients with PD and in controls. The typical diet was based on semisolid foods, usually vegetable soups accompanied by cereal flour or root starch or sometimes chicken or fish. The intake of milk and its derivatives was low. The prevalences of constipation and dysphagia in patients with PD were 49% and 21%, respectively.ConclusionThis study has yielded information that could be useful for the study of the management of PD and for the assessment of response to therapy.     

Nutritional status of social groups in greater metropolitan São Paulo, Brazil

This paper focuses on prevalence of nutritional status (Body Mass Index, BMI) in social groups in greater metropolitan S?o Paulo, in Southeastern Brazil. The population was stratified in four socioeconomic groups. Prevalence of malnutrition (BMI<18.5kg/m2), low body mass (BMI<20.0kg/m2), and overweight (BMI>25.0kg/m2) and obesity (BMI(30.0kg/m2) were calculated. Prevalence of malnutrition was 3.9% in men and 6.2% in women. Prevalence of overweight ranged from 27.5% to 34.1% in men and from 25.8% to 43.6% in women. Obesity ranged from 2.5% to 11.1% in men and from 7.1% to 20.5 in women. Prevalence of overweight and obesity was greater among women than men (p<0.01). In relation to excess weight (BMI>25.0kgm/2), the study showed that prevalence in men was 43, 51, 35, and 30% for strata I, II, III, and IV, respectively. Among women, prevalence was 12, 61, 55 and 46% for strata I, II, III, and IV, respectively. In women there were an abrupt increase in excess weight just before 40 years of age. A high percentage of overweight and obesity was observed in all population groups.     

Nutritional status of children in rural Lao PDR: who are the most vulnerable?

A cross-sectional study was undertaken to assess the nutritional status of children aged 3-15 y in remote villages of Lao PDR. Study sites were chosen from two provinces: Luang namtha (north) and Sekong province (south). All the sampled 1075 children were measured for anthropometry, following the standard methods. Dietary intake, morbidity and socio-economic data were obtained by interviews with parents. This study confirmed the high prevalence of growth retardation among children, as well as persistent food insecurity in the remote areas of Lao PDR. Prevalence of stunting was 74.1% in Luang namtha and 62.6% in Sekong province, with school-aged children being worse-off than under-five ones. Children's diets were inadequate in quality as well as in quantity, with very limited availability of rice and other food items throughout the year. Our findings also suggest the negative outcomes of government's development programme were often overlooked, and that more attention should be paid on the fragile living conditions in the resettlement villages, especially for the ethnic minority.     

Nutritional and functional status in geriatric day hospital patients–MNA short form versus full MNA

Objectives

The aims of this study were to determine the prevalence of malnutrition in patients of a geriatric day hospital using the Mini Nutritional Assessment short form (MNA-SF) and the full MNA, to compare both tools, and to examine the relationship between nutritional and functional status.

Design

Cross-sectional study.

Setting

Geriatric day hospital.

Participants

190 patients (72.1% female, median 80 years) aged 65 years or older.

Measurements

In consecutively admitted geriatric day hospital patients nutritional status was assessed by MNA-SF and full MNA, and agreement between both tools calculated by Cohen’s kappa. Basic activities of daily living (ADL), instrumental activities of daily living (IADL) and short physical performance battery (SPPB) were determined and related to MNA categories (Chi²-test, Mann-Whitney-U-test).

Results

36.3 % and 44.7% of the patients were at risk of malnutrition, 8.9 % and 5.8 % were malnourished according to MNA-SF and full MNA, respectively. Agreement between both MNA forms was moderate (?=0.531). No significant associations between MNA-SF and ADL, IADL and SPPB, and between full MNA and SPPB were observed. According to full MNA, the proportion of patients with limitations in ADL and IADL significantly increased with declining nutritional status (ADL: 2.1 vs. 8.2 vs. 18.2 %, p=0.044; IADL: 25.5 vs. 47.1 vs. 54.5 %, p=0.005) with a simultaneous decrease of the proportion of patients without limitations. Well-nourished patients reached significantly higher ADL scores than patients at risk of malnutrition (95 (-100) vs. 95 (85- 100), p=0.005) and significantly higher IADL scores than patients at risk or malnourished (8 (6-8) vs. 7 (5-8) vs. 6 (4-8), p=0.004).

Conclusion

The high prevalence of risk of malnutrition and the observed association between functional status and nutritional status according to full MNA call for routine nutritional screening using this tool in geriatric day hospital patients.

     

Nutritional status in Parkinson’s disease patients undergoing deep brain stimulation surgery: A pilot study

Objectives

People with Parkinson’s disease (PD) are at higher risk of malnutrition due to PD symptoms and pharmacotherapy side effects. When pharmacotherapy is no longer effective for symptom control, deep-brain stimulation (DBS) surgery may be considered. The aim of this study was to assess the nutritional status of people with PD who may be at higher risk of malnutrition related to unsatisfactory symptom management with optimised medical therapy.

Design

This was an observational study using a convenience sample.

Setting

Participants were seen during their hospital admission for their deep brain stimulation surgery.

Participants

People with PD scheduled for DBS surgery were recruited from a Brisbane neurological clinic (n=15).

Measurements

The Patient-Generated Subjective Global Assessment (PG-SGA), weight, height and body composition were assessed to determine nutritional status.

Results

Six participants (40%) were classified as moderately malnourished (SGA-B). Eight participants (53%) reported previous unintentional weight loss (average loss of 13%). On average, participants classified as well-nourished (SGA-A) were younger, had shorter disease durations, lower PG-SGA scores, higher body mass (BMI) and fat free mass indices (FFMI) when compared to malnourished participants (SGA-B). Five participants had previously received dietetic advice but only one in relation to unintentional weight loss.

Conclusion

Malnutrition remains unrecognised and untreated in this group despite unintentional weight loss and presence of nutrition impact symptoms. Improving nutritional status prior to surgery may improve surgical outcomes.     

Nutritional status and associated factors among the elderly in Viçosa, Minas Gerais State, Brazil

This cross-sectional study in 2009 focused on the prevalence of underweight and overweight and associated factors in a sample of 621 elderly individuals in Vi?osa, Minas Gerais State, Brazil. Data were obtained through home interviews on nutritional status and socio-demographic and health conditions. Of the total sample, 53.3% were females. Median BMI was 26.40 kg/m2 (range = 15.20-46.82) and was lower for men than for women. Prevalence of overweight was high (45%; 95%CI: 40%-49%), decreased with age, was positively associated with female gender and history of arthritis/arthrosis, and was negatively associated with age 80 years or older and smoking. Prevalence of underweight was high in men (18.2%), increased with age, and was positively associated with worse self-rated health. The findings highlight the importance of health strategies that favor lifestyle changes and healthy eating habits.

Nutritional–pharmacological combinations

Summary Background Recent studies have suggested that n–9 fatty acids in olive oil prevent colon carcinogenesis while n–6 PUFA seems to activate this process. Aims To evaluate the effects of nutritional–pharmacological combinations made up of olive or soy oilbased diets and the drug sulindac, on colon cancer incidence in a chemically induced (1,2–dimethylhydrazine, DMH) rat cancer model. Methods Male rats were assigned to two different dietary regimes based on a standard murine defined diet (AIN–76A) containing either a low (4%) or high (15 %) concentration of olive or soy oil. Some groups also received sulindac in their food (80 mg/kg food) starting from the ninth week following the first DMH or vehicle administration. Results Oleic and linoleic acid reached higher levels in plasma and liver lipids when rats were fed high concentrations of olive or soy oil, respectively. Rats fed a low or high soy oil–based diet showed no significant difference in the number of aberrant crypt foci (ACF) in proximal or distal colon specimens. In contrast, rats fed a higher olive oil–based diet developed a significantly lower number of ACF than rats fed a low concentration of olive oil. Addition of sulindac reduced the number of ACF in rats fed the 4%, but not the 15%, soy oil diet. In contrast, the effect of sulindac was significant when combined with both the low and high concentrations of olive oil. High soy oilbased diet or DMH treatment upregulated colon expression of Bcl–2, but not that of cyclooxygenase–2 (COX–2). In contrast, olive oil dose–dependently downregulated the expression of both Bcl–2 and COX–2 in colonic mucosa and also abrogated the upregulation of Bcl–2 by DMH. Olive oil/sulindac combinations were effective in downregulating colonic mucosa Bcl–2 expression (with the 4% oil diet) and COX–2 expression (with the 15% oil diet). These effects were not observed in rats fed the soy oil/sulindac combinations. Caspase–3 activity in colonic mucosa was unaffected by soy oil or soy oil/sulindac combinations. The addition of olive oil, on the other hand, significantly enhanced colonic caspase–3 activity. Conclusions Diets containing high levels of olive oil exert a significant protective effect from tumor development that is additive with the inhibitory effect of sulindac. These inhibitory effects are mediated by regulating the expression and activity of key proteins involved in prostaglandin–biosynthesis and apoptosis–induction pathways. It may be concluded that appropriate dietary–pharmacological combination can improve anti–tumor efficacy over either dietary or pharmacological intervention alone.     

Aging: a barrier to renutrition? Nutritional and immunologic evidence in rats

BACKGROUND: Previous reports suggest that correcting the malnourished state is more difficult in elderly people than in younger ones and that protein requirements may be higher in elderly than in younger adults. OBJECTIVE: The aim of this study was to establish whether malnourished old rats respond to protein-supplemented nutritional repletion as do young adult rats. DESIGN: Adult (3 mo old) and old (22 mo old) rats were submitted to dietary restriction programs that induced similar metabolic and nutritional alterations. Malnourished adult and old rats were then killed (R groups) or refed for 1 wk with a high-protein diet (HPD; 23% protein) or a very-high-protein diet (VHPD; 27% protein). Control groups at both ages were fed ad libitum throughout the experiment. Effects of food repletion were evaluated in terms of protein metabolism, intestinal histomorphometry, and nonspecific immune status. RESULTS: In adult rats, HPD sufficed to increase body weight and restore basal values of liver weight and protein content (P: < 0.01 compared with the R adult group), nitrogen balance (P: < 0.01 compared with the R adult group), and hydrogen peroxide production by polymorphonuclear neutrophils and monocytes (P: < 0.01 compared with the R group); VHPD had no supplementary effect except on nitrogen balance. In old rats, HPD was less effective and greater benefit was observed with VHPD in terms of body weight gain (10%; P: < 0.01 compared with the old group fed HPD), albuminemia, muscle weight and protein content, plasma arginine concentration, and hydrogen peroxide production by stimulated polymorphonuclear neutrophils and monocytes compared with the old R group (P: < 0.01). CONCLUSION: Aging is a significant variable affecting the response to nutritional support.     

Nutritional support in patients with advanced cancer: permission to fall out?

Data from the European Society for Parenteral and Enteral Nutrition Home Artificial Nutrition Survey suggest that the use of home parenteral nutrition (HPN) in patients with cancer as the primary diagnosis varies markedly between different countries in Europe, being highest in The Netherlands and low in the UK. This finding is difficult to explain on the basis of cancer incidence. The main indication for HPN remains malignant gastrointestinal tract obstruction, which occurs most frequently in gynaecological and colon cancers. The use of HPN should be planned in the light of the proposed cancer treatment and should be discussed beforehand with the patient. Before HPN is considered, a patient should typically require intravenous fluids to maintain hydration, be capable of self care, be able to control the treatment, have an expected survival of > or = 3 months and have no other available route of feeding. The effect of HPN on quality of life remains controversial, but nutrition is only one of the factors that influence the quality of life in cancer patients. The differing rates of HPN in Europe are probably related to cultural attitudes to incurable cancer as much as to meeting the nutritional needs of the patient.
