Objective: The study was to determine whether the Mini Nutritional Assessment (MNA) could be used as a tool to effectively identify
malnourished elderly in a non-Caucasian population.Design: The study was a part of a population-based multistage random sample survey.Setting: In-home face-to-face interviews.Participants: Randomly selected 1583 men and 1307 women, 65 years or older, in Taiwan.Measurements: Assessing nutritional risk status of participants with the Mini Nutritional Assessment.Results: The prevalence of malnutrition is 1.7% in elderly men and 2.4% in elderly women, 65 years or older. The proportion at risk
of malnutrition is 13.1%.Conclusion: To the best of our knowledge, this is the first study to apply the MNA to estimate the prevalence of malnutrition in the
elderly in a nationally representative sample. Results suggest that the MNA can identify malnourished elderly in a non-Caucasian
population. However, it appears that the functionality of the instrument can be improved by adapting population-specific anthropometric
cutoff standards.

Population-specific anthropometric cut-points improve the functionality of the Mini Nutritional Assessment (MNA) in elderly Taiwanese 总被引:1,自引:0,他引:1
The objective of this study was to determine the population-specific cut-points of body mass index (BMI), mid-arm circumference (MAC) and calf circumference (CC) for identifying subnormal nutritional status in elderly Taiwanese, and to evaluate the possibility of improving the functionality of the Mini Nutritional Assessment (MNA) by adopting these cut-points. This study analyzed data from 1583 men and 1307 women, 65 years or older, of a national survey. The survey involved in-home, face-to-face, interviews and anthropometric measurements. Results showed that based on the cumulative percentile curves, the fifth percentile values were: BMI, 17 kg/m2 for both men and women; MAC, 22.5 cm for men and 21 cm for women; and CC, 28 cm for men and 25 cm for women. Substitution of these population-specific cut-points for respective values in the MNA screen resulted in lowered proportions of elderly classified malnourished or at risk of malnutrition. The prevalence of malnutrition was reduced from 1.7% to 1.4% in men and from 2.4% to 1.5% in women. The proportions classified at risk of malnutrition were reduced from 10.1% to 8.9% for men and 16.8% to 12.8% for women. In conclusion, results suggest that the MNA is a valuable tool for geriatric nutritional risk assessment. However, in populations where significant differences exist in anthropometric measurements from the Caucasian populations, population-specific cut-points should be used. 相似文献

Malnutrition, a risk factor for osteoporotic fractures, is frequent in elderly people and, is underdiagnosed and undertreated. There are only few studies on the nutritional status of elderly people in Europe. The Mini Nutritional Assessment (MNA) is a non invasive and validated questionnaire to evaluate nutritional status in elderly people, classified in three groups: 1 degree score < 17: malnourished, 2 degrees score >17 and < 24: at risk of malnutrition, 3 degrees score >24: well-nourished, with a maximum of 30 points. Quantitative ultrasound of bone (QUS) is a method for assessing quality of bone which can be easily performed in nursing homes. Therefore, these two tests allowed to study the relationships between nutritional status and ultrasonic parameters of bone in 78 institutionalized women aged 86 +/- 6 years, living in 11 nursing homes around Lausanne (Switzerland). All were assessed by the MNA, had a measurement of the tricipital skin fold and of the grip strength. Functional status was evaluated by the scale "Activity of Daily Living" (ADL), and serum albumin level was measured when permitted. All had QUS of the calcaneus (with an Achilles, GE Lunar). The measured parameters are the Broadband Ultrasound Attenuation (BUA), attenuation of a band of ultrasonic frequencies through the medium, expressed in dB/MHz, and the Speed of Sound (SOS), speed of the ultrasounds through the medium, expressed in m/s. A third parameter, the stiffness index (SI), expressed as a percentage of the values obtained by the manufacturer in a young population and derived from BUA and SOS, was calculated automatically : SI = (0.67xBUA) + (0.28xSOS) - 420, expressed in percent compared to a young adult population (%YA). Fifteen percent of the women were undernourished and 58% were at risk of malnutrition. As expected, compared with the well-nourished minority, undernourished subjects had significant lower body mass index (BMI), tricipital skin fold (TSF), ADL score and albumin level (p < 0,01). The subjects "at risk of malnutrition" had significant lower BMI, ADL score (p < 0.01), tricipital skin fold and serum albumin (p < 0.05). Ultrasound parameters were low independently of the nutritional status. MNA score correlated significantly with tricipital skin fold (r = 0.508, p < 0.01), ADL (r = 0.538, p < 0.01) and albumin serum level (r = 0.409, p = 0.01). There was a trend for a correlation between the MNA and the ultrasound parameter BUA (r = 0.207, p = 0.07), whereas no correlation was found with SOS and SI. A multivariate analysis showed that tricipital skin fold and ADL explained 61% of the variance of the MNA. In conclusion, using simple and non invasive methods, this study showed that malnutrition and osteoporosis are frequent in institutionalized elderly persons in our country, and the ultrasound parameters are influenced by many others factors in addition to nutrition, especially at this age and in elderly residents of nursing homes. 相似文献

Objective of the study is to present an intervention model to evaluate nutritional risk of institutionalised elderly, suitably with the aims and resources of the Hygiene of Nutrition Services, and to individuate predictive variables of nutritional vulnerability. 237 subjects from the residential homes of ASL RMB were involved in the study; to each subject was administered: a) the Mini Nutritional Assessment (MNA); b) a questionnaire for the analysis of the risk factors. Multivariate logistic regression analysis was performed to evaluate the influence of the risk factors on nutritional status. On the basis of BMI the prevalence of malnutrition is 6.5% and the prevalence of overweight and obesity is respectively 41.6% and 22.9%; on the basis of MNA, 5.1% of the subjects is malnourished and 60.3% at risk for malnutrition. The absence of chewing difficulties (OR 2.94; I.C. 1.46-5.91) and the habit to eat all foods served at meals (OR 2.83; I.C. 1.46-5.91) are associated with a good nutritional status. The age > or = 90 years is a risk factor for malnutrition at the limit of statistical significance (OR 0.44; I.C. 0.14-1.00). Carrying out the MNA resulted easy and quick, confirming the hypothesis for feasibility of this protocol in the Hygiene of Nutrition Services. The results highlight an high nutritional risk of the elderly nursing home residents and the importance of planning programs of nutritional surveillance with particular attention on masticatory function impairments, meal intake and on the oldest subjects among the elderly as a group greatly vulnerable. We believe that these areas are very important in defining public health intervention programs. 相似文献

Objective: To assess the nutritional status of institutionalized Taiwanese elderly with the Mini Nutritional Assessment (MNA) without
BMI and to determine whether the application of population-specific MAC and CC cutoff standards would improve the functionality
of the tool.Design: Purposive sampling.Setting: A long-term care facility in central Taiwan.Participants: Two hundred and eight >65 y residents who were free of acute infection/diseases and were able to communicate.Measurements: A questionnaire survey to elicit personal data and administer the MNA and measurements of anthropometric and blood biochemical
indicators.Results: The MNA, without BMI, predicted 22.1% of participants malnourished and 61.1% at risk of malnutrition among residents of a
long-term care facility in Taiwan. Replacing the population-specific cutoff standards of MAC and CC for the original cutoff
standards in the MNA and increasing the weighted score of MAC and CC to replace for the weighted score of BMI preserved and
improved the predicting ability of the MNA. The improvement was evidenced by the increase in the correlationships between
the MNA scores and the anthropometric, biochemical or health status indicators.Conclusion: The MNA predicted nutritional risk status of the institutionalized elderly Taiwanese. The study suggests that whenever possible
population-specific anthropometric cutoff standards should be applied to improve the functionality of the MNA. It also appears
possible to preserve or even improve the functionality of the MNA without BMI. The modifications indicate an improvement in
the application of the MNA in long-term care patients. 相似文献

The evaluation of nutritional status in cancer patients is often neglected in spite of the fact that poor nutritional status may adversely affect prognosis and treatment tolerance. In day-to-day oncology practice, a sensitive but simply applied nutritional assessment tool is needed to identify at-risk patients. Several tools exist; however, none has been universally accepted. The aim of this study was to compare two potential tools, the Mini-Nutritional Assessment (MNA) and the scored Patient Generated Subjective Global Assessment (PGSGA). The MNA is more simply applied and does not require a trained dietitian. The PGSGA has been previously validated in cancer patients. One hundred fifty-seven newly diagnosed cancer patients were assessed using both tools. Of these, 126 were reassessed at 4-6 wk, and 104 were reassessed at Weeks 8-12 after initial assessment. A significant negative correlation was found between the tools at all three time periods (at baseline r = -0.76; P < 0.001). Taking the PGSGA as the most accepted nutritional assessment tool, at baseline the MNA demonstrated a sensitivity of 97% and specificity of 54%. At 4-6 wk MNA sensitivity was 79% and specificity was 69%. At 8-12 wk MNA sensitivity was 93% and specificity was 82%. When comparing the tools in elderly patients alone (>65 yr), similar results were obtained. Both tools were able to correctly classify patients as malnourished, although the MNA lacks specificity. Therefore, the PGSGA should be the tool of choice for nutritional assessment in cancer patients. 相似文献

The study was conducted to determine the effectiveness of a modified Mini Nutritional Assessment (MNA) for assessing the nutritional status and predicting follow-up mortality of institutionalized elderly Taiwanese. The study was conducted in a large long-term care centre in central Taiwan. Trained interviewers assisted by the caregivers elicited sociodemographic data, healthcare and disease history, and answers to the MNA screen from each subject. One researcher performed all subjects' anthropometric measurements. Plasma albumin and cholesterol concentrations were determined. Results showed that the MNA without BMI, modified according to population-specific mid-arm circumference and calf circumference cut-points, effectively predicted the nutritional risk status of the elderly regardless of cognitive status. Substituting caregiver's assessments for self-viewed nutrition and health status (questions O and P of MNA) improved the predicting power of the tool in cognition-normal subjects. Results showed that 21.9% of the elderly were malnourished, 59.2% were at risk of malnutrition and 18.9% were normal according to self-assessment whereas 14.2% were malnourished, 59.2% were at risk of malnutrition, and 26.6% were normal according to caregiver's evaluation. The tool was also effective in predicting 12- and 6-month follow-up mortality in cognition-normal and cognition-impaired elderly, respectively. Results indicate that a population-specific MNA can effectively predict the nutritional status and 6-month follow-up mortality of elderly Taiwanese regardless of cognitive condition. Easier and wider application of the tool will enable early detection of emerging nutritional problems and timely intervention to prevent the development of severe malnutrition in the elderly. 相似文献

ObjectivesThe Mini-Nutritional Assessment (MNA) is recommended to assess malnutrition in older people. However, its implementation is challenging in large elderly population, nursing home, or community or large clinical research programs. The Simplified Nutritional Appetite Questionnaire (SNAQ), a self-assessment nutritional screening tool that predicts weight loss, could be used to screen older people at risk of malnutrition or malnourishment. Our objective was to assess whether the SNAQ is related to the MNA and can screen older people at risk of malnutrition or malnourishment.Design/Setting/ParticipantsCross-sectional study conducted of 175 persons aged 65 or older who were community dwelling, hospitalized, and nursing home residents.MeasurementsThe SNAQ and the MNA score were performed. Correlation between the scores was studied. The most discriminating SNAQ value, which separated the participant at risk of malnutrition or malnourishment from the participant with a normal nutrition status (defined by MNA), was calculated.ResultsThe SNAQ and the MNA score were significantly correlated (Spearman test r = 0.48, P < .001). The distribution of the population using the SNAQ or the MNA was significantly different (MacNemar P < .01). The area under the receiver operator characteristic curve, which assesses the ability of the SNAQ score to predict an abnormal MNA score, was 0.767 (95% confidence interval, 0.69–0.85). An SNAQ score under 14 was the best clinical indicator of older people at risk of malnutrition or malnourishment (sensitivity = 71%, specificity = 74%). Using this cut-off, 26.8% of the population (n = 47) were misclassified. Most of them (n = 33; 18.8%) had an abnormal SNAQ with a normal MNA.ConclusionThe SNAQ is a poor screening tool to predict older people with an abnormal MNA score. However, an abnormal SNAQ might identify those who will lose weight earlier than will the MNA. 相似文献

This study aimed to evaluate the usefulness of the Mini Nutritional Assessment (MNA) to assess nutritional status of Iranian population and to compare its psychometric properties between patients suffering from a chronic disease, healthy elderly and younger adults. As a group of elderly with a chronic disease, 143 Parkinson’s disease (PD) patients and as the control group, 467 healthy persons were enrolled. The Persian-translated version of MNA was filled-up through interviews together with anthropometric measurements. Cronbach’s α coefficient of entire MNA was 0.66 and 0.70 in healthy individuals and PD patients, respectively. The total MNA score could significantly discriminate the ones with BMI ≥ 24kg/m2 in both groups. In general, MNA was a valid and reliable tool for nutritional assessment. We acknowledge study limitations including lack of serum measurements and a selection bias towards mild-to-moderate PD. MNA is a more reliable tool in older healthy individuals and rather younger elderly with PD. 相似文献

Risk factors associated with falls and injuries among elderly institutionalized persons 总被引:6,自引:0,他引:6

A case-control study among 184 matched pairs of patients 65 years of age and older was undertaken to identify risk factors associated with falls and injuries in a long-term care facility in Baltimore, Maryland, in 1984-1985. Patients were matched on length of stay. Variables of interest included sociodemography, functional status, medications, and diagnoses. For all levels of care combined, the following factors were associated (p less than or equal to 0.01) with increased falls: being able to walk (relative odds (RO) = 4.0), age 90 years and older (RO = 3.8), a history of falling (RO = 5.0), and taking a vasodilator (RO = 3.0). Among the 184 fallers, the diagnosis of dementia (RO = 7.5) or taking a diuretic (RO = 7.2) was positively associated with injury (p less than or equal to 0.01). In each of the analyses, medications were associated with falls or injuries, suggesting a feasible intervention. The combination of a history of falling, being able to walk, and being 90 years of age or older increased the relative odds to 51.9 and could alert clinicians to identify and monitor high-risk elderly persons in need of preventive measures. 相似文献

Abstract Objective: To monitor the nutritional status of patients with Parkinson's disease using the Mini Nutritional Assessment (MNA) questionnaire. Patients and methods: This was a 3-year longitudinal study conducted in a national referral centre for Parkinson's disease and other movement disorders. The cohort included 61 Parkinson's disease patients, 37 men and 24 women, mean age of 70.5 ± 5.5 years, mean duration of disease 9 ± 6.3 years; 35 patients were followed-up after 3 years. Results: MNA score diminished from 24.9 ± 1.6 to 24 ± 2.5 (P = 0.02); the proportion of patients at risk of malnutrition increased from 22.9% to 34.3%. A linear correlation was observed between MNA score and the duration of disease (P = 0.0096). The dietary assessment subscore significantly diminished (8.6 versus 8.1; P = 0.0009) as did body mass index (25.9 ± 3.5 kg/m2 versus 27.1 ± 3.1 kg/m2; P = 0.001). Conclusions: The evaluation of nutritional status should be part of the routine work-up of a Parkinson's disease patient. Dietary education should be included amongst the therapeutic measures designed to improve the general conditions in Parkinson's disease. 相似文献

The use of the Mini-Nutritional Assessment (MNA) tool in elderly orthopaedic patients 总被引:4,自引:0,他引:4
OBJECTIVE: To assess the use of the Mini-Nutritional Assessment (MNA) in elderly orthopaedic patients. DESIGN: An observation study assessing the nutritional status of female orthopaedic patients. SETTING: The orthopaedic wards of the Royal Surrey County Hospital. SUBJECTS: Forty-nine female patients aged 60-103 y; dietary records were obtained for 41 subjects and 36 subjects gave a blood sample for biochemical analysis. MAJOR OUTCOME METHODS: MNA questionnaire, anthropometry, plasma albumin, transferrin, C-reactive protein (CRP) levels and dietary analyses. RESULTS: The group as a whole had low mean values for body weight, albumin and transferrin and high CRP levels. In addition, the group had mean energy intakes well below the estimated average requirement (EAR) and mean intakes of vitamin D, magnesium, potassium, selenium and non-starch polysaccharides (NSP) were below the lower reference nutrient intakes (LRNI). The MNA screening section categorized 69% of the patients as requiring a full assessment (scored 11 or below), but for the purposes of the study the MNA was completed on all patients. The MNA assessment categorized 16% of the group as 'malnourished' (scored<17 points), 47% as 'at risk' (scored 17.5-23.5) and 37% as 'well nourished' (scored>23.5). Significant differences were found between the malnourished and well nourished groups for body weight (P<0.001), body mass index (BMI) (P<0.001), demiquet (P<0.001) and mindex (P<0. 001). Mean values for energy and nutrient intakes showed a clear stepwise increase across the three groups for all nutrients except sodium, with significant differences for protein (P<0.05), carbohydrate (P<0.05), riboflavin (P<0.05) niacin (P<0.05), pyridoxine (P<0.05), folate (P<0.05), calcium (P<0.05), selenium (P<0.05), iron (P<0.05) and NSP (P<0.05) intakes. Stepwise multiple regression analysis indicated that anthropometric assessments were the most predictive factors in the total MNA score. The sensitivity and specificity of the MNA was assessed in comparison with albumin levels, energy intake and mindex. The sensitivity of the MNA classification of those scoring less than 17 points in comparison with albumin levels, energy intake and mindex varied from 27 to 57% and the specificity was 66-100%. This was compared with the sensitivity and specificity of using a score of less than 23.5 on the MNA to predict malnourished individuals. Using this cut-off the sensitivity ranged from 75 to 100%, but the specificity declined to between 37 and 50%. CONCLUSIONS: The results suggest that the MNA is a useful diagnostic tool in the identification of elderly patients at risk from malnutrition and those who are malnourished in this hospital setting.

BACKGROUND AND GOAL: Age and malnutrition are each surgical risk factors. Because the Mini Nutritional Assessment (MNA) has been specifically designed for assessing the nutritional status of elderly patients, it can be used for preoperative nutritional evaluation. Therefore, the MNA was included in the preoperative clinical evaluation of patients over 60 years of age to describe their nutritional status. METHODS: Every patient over 60 years of age, scheduled for elective surgery, was seen in anaesthesiology consultation and was submitted to the MNA. The MNA is a clinical score consisting of four additive items: 'Anthropometric assessment' based on BMI, mid-arm and calf circumferences, weight loss; global evaluation; dietetic assessment, and subjective assessment - these last three items being obtained through a specific questionnaire. It requires no biological marker. Awarding to the obtained score, the MNA stratifies patients in the following categories: well-nourished (24 = MNA = 30), at risk of malnutrition (17 = MNA < 23.5), and undernutrition (MNA < 17). Also recorded were: age, gender, type of scheduled operation, and the American Society of Anesthesiologists (ASA) physical status score. Results are given as median (extremes). RESULTS: Four hundred and nineteen patients (50.4% women) were seen between January and October 1996. The mean age was 72 years (range, 60-98 years); BMI: 25.2 (12.8-40.4) kg m(-2). The MNA score was recorded in 408 patients, ranging from 1.5 to 30 (median: 26). According to the score, the patients were stratified in: well-nourished, 276 patients (67.6%), at risk, 104 patients (25. 5%) and suffering from overt malnutrition, 28 patients (6.9%). According to the ASA score, 290 patients were found to be at low or mild risk for anaesthesia and surgery (ASA 1 and 2), and 72 patients (24.8%) were stratified as being at least at risk of malnutrition. One hundred and eighteen other patients were found to be at a higher risk (ASA 3 and 4), and 58 (49.2%) were not well-nourished (MNA < 24). CONCLUSION: The MNA was found to be well-suited for the preoperative assessment during anaesthesia consultation because it required no biological marker. It showed that approximately one-third of all the examined patients, and half of the ASA 3-4 patients, were not well-nourished. The ASA score could not predict poor nutritional status. The results suggested that nutritional assessment should be routinely performed in ASA 3-4 patients over 60 years of age. 相似文献
